WILLIAM E. BUDD, OF GHATHAM, NEW JERSEY, AND FRANK SICKELS, OF CHICAGO, ILLINOIS.

COMBINED LATCH AND LOCK.

SPECIFICATION forming part of Letters Patent No. 372,961, dated November 8, 1887.

Application filed May 20, 1887. Serial No. 238.914. (Modoh) To all whom it may concern:

Be it known that we, WILLIAM E. BUDD, of Ohatham, in the county of Morris and. State of New Jersey, and FRANK SIcKELs, of Chicago, in'the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in aOombined Latch and Look; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

Our invention relates to an improvement in a combined latch and lock; and it consists in, first, the combination of the key-postfwhieh is weighted upon one side, so as to return au .tomatically to position after having been moved, and which has notches in the edges of the weighted portion, a pivoted sliding plate, which is placed in a recess formed in the edge of the weighted portion and which has its inner edge to extend down far enough to be operatedby the key when 'it is inserted into the key-hole, and a pivoted lever provided with projections to catch in the notches in the keypost,and thus prevent the post from automatically returning to position, after having been moved by the key,and rclocking the door; second, the combination of the latch-bolt having a notch formed in its lower edge with the recessed locking-lever, which is operated by the pivoted arms or levers connected to the escutcheon-plates, and which have their inner ends to extend under the locking-bolt, and thus raise it upward, so as to cause it to engage with the latch-bolt; third, the combination of the spindle-post provided with notches in its edge, the latch-bolt provided with a recess in its edge, a locking-lever provided with a projection to engage with the notches on the spindlepost, and the pivoted levers connected to the escutcheon-plates, whereby when the lockinglever is raised it looks back both the latch-bolt and the spindle-post at, the same time; fourth, the combination of the hollow castings or frames, which are applied to the outer opposite sides of the look at thekey-hole, the automatically-moving slide, which is placed in each frame, and which has its inner end to project slightly down over the key-hole and into the notch in the revolving casting through which the key-hole is made, so as to be raised whenever the key is inserted,-and the plates and washers, which are placed inside of the castings, as will be more fully described hereinafter;

The objects of our invention are to provide an automatic lock for the slotted revolving casting through which the key-hole is made, so that when it is attempted to insert a skeleton key or flat object to pick the look its entrance will either be prevented or it will be found impossible to turn it around, because the casting through which the key-hole is made is locked in position, to use a locking-lever in connection with the weighted automaticallyacting key-post, so that when the key-post has been turned around to unlock the door thelever will engage with the key-post and prevent it from automatically re-engaging with the latch-bolt and also prevent the look from being picked, and to provide a means for locking the latch-bolt back, so that it will not engage with the striking-plate when the door is closed.

Figure 1 is an edge view of the lock complete, showing the escutcheon-plates in position. Fig. 2 is a side elevation of the lock with one of the side plates removed, showing the parts in one position. Fig. 3 is a similar view, showing the parts in another position. Fig. 4 is an edge view of the key-post and its attachment-s. Fig. 5 is a vertical section taken through the key-post.

Fig. 7 is a horizontal section taken through the escutcheon-plate, showing the device which holds the knob in position. Fig. 8 is a side elevation taken from the inner side of the hollow casting, which is applied to the outer side of the key-hole. Fig. 9 is a vertical section taken through the same. Figs. 10 and 11 are detached views of the hollow castings and the different-shaped washers used in connection therewith. Fig. 12 is a perspective of the slide used in connection with the frame 0. Fig. 13 is a horizontal section taken through the striking-plate. Fig. 14 is a side elevation of the striking-plate.

A represents the frame of a mortise-lock,

and 13 its face-plate. This faceplate B is provided with a flange or projection, O, on its nner edge, which extends a suitable distance in between the two sides of the frame, and through which flange or projection is formed a suitable opening to engage the screw-post, and thus secure the face-plate in position. Near each end of the face-plate is formed a flange, D, which catches over one of the corners of the frame and assists in holding the face-plate in position, by preventing any endwise movement of the plate which would interfere with the movement of the latch-bolt E. The latchbolt E is pivoted in the upper front corner of the lock-frame, and a spring is here shown for the purpose of returning the bolt to position after having been moved; but this spring is not absolutely necessary. Formed as here shown, the latch-bolt will instantly act from gravity alone, so that the use of a spring 15 entirely optional. The latch-tumbler F, by which the latch-bolt is operated in the usual manner, has a series of projections or ratchetteeth formed in its edges, for the purpose of engaging with the projection upon the lockingbolt G, which is pivoted in the lower rear corner of the lock-frame. This locking-bolt G is provided with a recess in the top of its free end, so as to engage with a projection. H,whieh is formed upon the latch-bolt E. \Vhen it is desired to hold the latch-bolt back in thelockframe, so that it will not engage with the striking-plate, the'latch-bolt is forced back, and then the locking-bolt G is raised upward by one of the pivoted levers I, connected to the escuteheon-plates J, and while the lockingbolt G holds the latch-bolt E back in position the projection on thelever G engages with one of the notches in the latch-tumbler F and looks it in position at thesame time, so that the knob cannot be turned. This construction prevents any rattling of the knobs when the lock is used upon a fly-door. A pivoted lever, I, may be attached to each one of the escutcheon-pla-tes, so that the latch-bolt may be locked from either side of the door, and thus prevent it from operating. By means of the construction here shown the levers I are made entirely separate and independent of each other, and thus the door may be locked and bolted from both sides of the door at once, or from one side only.

The upper inner corner of the latch-bolt E is recessed, as shown, and the edges of this reeessed portion are notched, so that the pawls K,pivotcd to the key-postL,will automatically engage therewith, and thus prevent the keypost from being turned unless the proper key is used. These pawls and the key post weighted upon one side are fully shown and deseribedin the former application filed by us, and hence need not be more fully described in this application. The weighted side of the key-post L is recessed, as shown, and in this recess is placed the movable plate M, which has a projection on its inner edge, so as to project down across the upper end of the keyhole. When the key is inserted, one of its edges strikes against this projection, and thus lifts the movable plate M upward until its outer edge becomes flush with the edge of the weighted portion of the post L, which is provided with two notches, as shown. \Vhen this plate M is in its normal position, its outer edge comes below the edge of the weighted portion of the post L; but as soon as the key is inserted its outer edge is forced upward, so as to be flush with the recessed edge of the post L.

Iivotcd in the inner upper corner of the lock-frame is the lever N, which is provided with two projections on its lower edge corresponding to the recesses made in the edge of the key-post. This key-post, being weighted upon one side, would automatically return to place as soon as the key was removed, unless the post was turned entirely around, and thus lock the door again,when perhaps it was not desired that the door should he relocked. In order to prevent this reloeking of the door, as well as assist in preventing the lock from being picked, the lever N is used. When the key is inserted in the post L, one of its edges forces the plate M upward, so as to be just flush with the weighted portion of the post, and in this position it prevents either one of the projections on the locking-lever N from engaging with the recesses in the post. As soon as the key is withdrawn the plate M sinks downward from its own gravity, and then one of the projections on the lower edge of the leverN can engage with one of the notches in the key-post. \Vhen the key-post is turned only partially around by either the proper or a false key, the two projections upon the lever N enter both of the recesses in the post L, in which position the post is locked in place in such a manner that thelatch-bolt E cannot be operated. If, however, the turning movement of the post is continued until its rear edge strikes against the stop provided for it, only one of the projections 011 the lever N will engage one of the notches in the key-post, and in this position the key-post is prevented from automatically turning and again locking the door.

Should some sharp instrument be inserted into the look so as to operate only the pawl K upon that edge of the key-post, the pawl upon the other side would still not be operated, and by engaging with the latch-bolt E would prevent the key-post from being turned farther around and thelateh-bolt from beingoperated. \Vhen the proper key isinserted into the post L, its first operation is to force the plate M upward, and thereby raise the projection or projections on the lever N out of the recess or recesses in the key-po st, and thus leave the post free to be turned. As the insertion of the key also operates the pawls K, the post is free to be turned in either direction.

Applied to opposite sides of the lock-frame and to opposite ends of the key-post L are the recessed frames 0, in which the revolving of the knobs.

slotted casting P, having the key-hole made. therein, and the plates Q and the washers a, are placed. The casting Pis provided with a flange around its edges,which catches against the inner side of the frame 0, and the opposite edges'of this flange are notched or recessed, so as to engage with the slide S. There may be any desired number of the plates Q and the washers a placed in the frame, and these will be arranged so as to correspond to the re cesses made in the opposite edges of the key. Each plate Q represents one of the pair of notches in the key, and the washers a,of which there may be any desired number placed between the plates Q, represent the distance between the notches in the edges of the key. Placed in a suitable recess, 1), formed in the frame 0, is a slide, S, which has its inner end to project inwardly into the frame Oand catch in one of the notches formed in the flanges formed in the casting P. This slide sinks inward from its own gravity, and has its inner end to project downward partly across the key-hole, so that if the proper key is inserted the key must first raise the slide S, so as to detach it from the casting P, and thus leave the casting free to revolve. Should it be attempted to insert a skeleton key or a sharp tool into the key-hole, it must first operate the slide S, so as to free the casting P, or else the tool or key cannot be turned around, for the reason that the casting P, in which the key-hole is made, is locked in position. After the key or tool has been inserted into the frame 0 the notches in its edges must correspond to the plates Q,or it cannot be turned. As shown, two of these frames 0 are applied to each look. If so desired, these frames may be the same upon both sides, or different, as may be preferred. When'made different, a separate key will be required for each side of the door, thus making it impossible for a party upon one side of the door to operate the look without consent of the party upon the opposite s1 e.

The great advantage of the use of the frames 0 consists in makingthe combination entirely independent of the lock. These frames 0 may be removed by simply taking off the escutcheon-plates, and the combination changed without in any wise removing or interfering with any other part of the lock. The outer portion or end of theframe being made to extend into the socket formed in the plate J, the plate can be adjusted back and forth in relation to this end of the frame, and hence the same lock may be applied to doors which vary very materially in thickness.

The escutcheon-plates J are applied to opposite sides of the door, and are provided with openings for the passage of the outer ends of the frames 0, for the knob, and for the screws which hold the escutcheon-plates in position.

The knobs are recessed, so as to receive the ends of the spindle,which is placed loosely in the lock and entirely disconnected from both In order to hold the knob in position, each one of them has a groove, T, formed in the inner end of the shank, just at that point where it passes through the plate J, and in this groove T is made to catch the inner end of the plate U, which has its inner end so shaped as to catch in the groove T, and thus hold the knob in place, while the outer end of the plate catches'against the flange formed on the edge of the escutcheon-plate J. The knobs are thus swiveled in position upon the eseutcheon-plates, instead of having to be fastened to the ends of the spindle, in the usual manner. The knobs, being thus swiveled in position, cannot be taken by removing any part,-as is the case with the ordinary lock, and are held more securely in position in every I n order to prevent either one of the escutcheon-plates from being taken from the door, there is formed upon its inner side a screw socket, Z, to receive the end of the screw which is passed through the escutcheonplate upon the opposite side of the door. This screw passes through one escutcheonplate upon one sideof the door, through both door and lock, and then its end catches in the screw socket in the other plate. The escutcheon-plate cannot be removed from the door without removing the screw from the escutcheon-plate upon the opposite side also. By this construction the escutcheon -plates, the knobs, and the frames 0 are prevented from being taken from the door, at the same time that it helps to prevent the burglars getting access to the working parts of the look. In order to prevent that part of thelatch-bolt which extends beyond the face plate B from being sawed off, one or more holes are to be drilled in it, and in this hole or holes are to be placed plugs d, of highly tempered metal, which will resist the action of any saw or file which the burglars may attempt to use. These plugs will prevent this portion of the latch-bolt from being sawed off, so that the door cannot be opened and the lock cannot be picked.

The, striking-plate is shaped as shown in Figs. 13 and 14;and it consists of a single casting, W, having a recess, X, at its inner end, and a suitable guiding-plate, Y, projecting from the center of one side, as shown. The latch-bolt moves along the plate Y until it reaches the recess X,when it snaps outward into it. The screws which hold this plate in position are passed through holes made in the bottom of the recess X, instead of in the outer ends of the plates in the usual manner.

We claim- 1. The combination of the latch-bolt provided with a projection, H, and a recessin its lower edge,the locking-lever G, provided with a recess in its end to receive the projection H onthe latch -bolt, and the pivoted levers I, connected to the escutcheon-plate J and having their ends to project through an opening in the lock-case, so as to engage with the lever G, and thus enable the lock to be deadbolted from either side of the door, substantially as shown.
