DEVICE FOR FASTENING DOORS, WIHDOWS, AND THE l'illKlil;

Application filed October 5, 1927. Serial No. 22%,212.

This invention relates to devices for fastening doors, windows and the like an d has particular reference to devices for holding doors or windows ajar in different positionsrfor ventilation.

One of the objects of the invention is to provide an apparatus of the kind mentioned which is rugged and noiseless for ships and trains, although it is at the same time suitable for use in houses and other buildings where anything of the kind may be needed.

Another object of the invention is to provide a device of the kind mentioned which cannot be detached or disconnected from the outside even though the door or window is open as far as the device will permit it to go.

With the foregoing and incidental objects in View the invention consists in a novel construction and arrangement of parts, the novel features of which are pointed out in the claims appended hereto, and an illustrative embodiment of which is shown in the drawings accompanying and forming a part of this specification.

In said drawings:

Fig. 1 shows in elevation the various parts of the apparatus in the positions they occupy when the device is not in use.

2 is a top plan view partly in section 90 showing the parts in the positions they occupy when the device has been operated to hold a door ajar.

Fig. 3 is a side view of the apparatus with the parts in the same positions as they occupy in Fig. 2.

Fig. 4c is a section on the line ie-4 in Fig. 1.

Fig. 5 is a section on the line 55 in Fig. 1.

Described in general terms the apparatus shown in the drawings comprises two plates, one of which is secured by screws or the like to the door jam and the other is similarly fastened to the door. Each of these plates has a dove-tail member adapted to be engaged by a dove-tail groove in the base of a co-operating part of the apparatus so as to permit a sliding engagement of the parts. Tn each instance the base of the member carrying the dove-tail groove is large enough to cover the screws used for attaching the plates to the door and door jamb, thereby making it impossible to get at the attaching member until the parts have been disconnected by disengaging the dove-tail and dovetail groove.

In order to prevent an accidental disconneetion. of the dove-tailed parts on both the door and the door jamb small locking screws used to .hold the two parts in engagement. These locking screws are preferably below the adjacent surfaces of the connected parts and cannot readily be located and removed while the door is locked ajar. Even if they could be removed the organization is such that the dove-tailed parts cannot be disengaged from the outside. In order to contribute further to the security of the appa ratus, each of the locking screws may be pro vided with a drop of solder on its head to cover and conceal the screw slot. If the solder is used as suggested, a new slot. can be cut in the solder across the head of the screw when it is desired to remove the locking screw preparatory to disconnecting the 'dovetailed parts.

The device in the drawings also comprises an arm or link which has a ball-socket connection with the parts attached to the door frame, with the adjacent walls of the socket so shaped as to limit movement of the arm or link to horizontal and vertical planes. The movement in the horizontal plane is to permit engagement of the arm or link with a lock bolt and movement of the door to different positions, while the movement in the vertical plane is to permit swinging the arm or link down out of the road when the apparatus is not in use. A spring co-operting with the ball in the ball and socket joint serves to insure frictional engagement of the ball and" socket and cooperates with a'leaf spring latch engaging the arm or link when the latter is depressed in a vertical plane to hold the arm or link from rattling when the apparatus is not in use.

Describing the apparatus more in detail and with particular reference to the drawings, the door jamb 10 and door 11 are respectively equipped with plates 12 and13, fastened in position by means of screws 14. The plates are counter-sunk to accommodate the heads of the screws so thatthe heads are flush or below the adjacent surfaces of the plates.

The plate 12 is provided with a dove-tail 16 which tapers slightly relative to the edge of the door jamb. Associated with the plate 12 is a member 17 carrying in its base a dovetail groove 18 cooperating with the dove-tail 16. The base of the member 17 is of sufficient .eXtent to cover and conceal the screws 14 ized disconnection of the member 17 and plate 12, both the member and plate are pro ided with holes for a small screw 21. The member 17 is counter-sunk so that the head of the screw 21 isbelow the adjacent surface and, as before stated generally, the head o1 the screw 21 may be given a drop oi solder so as to-cover and conceal the slot in its head.

The member 17 is shaped to form a socket 22 in which ismounted a ball 23 on the end of an arm or link 24. (lo-operating with the ball 23 is a spring 25 which tends at all times to hold the ball in good t'rictional contactwith the interior of the socket 22.

The portion of the element 17 which con tains the socket 22 is cut away as shewn at 27 and 28 to clear a reduced portion 29 on the arm 2a. In fact, the lower part oi the socket is cut out deeply enough (as shown at 31) to permit swinging the arm 2t down in a vertical plane to a vertical position (as shown in Figs. 3 and 5) when the device is not in use.

Fastened between the plate 12 and the member 17 is an element 32, the other end of which is secured to the door amb by a screw Integral with the member are two leaf-springs 3a suitably shaped to engage with a slot 35 extending substantially the full length of the arm 24. The parts of the springs 34 which engage the arm 2st are so shaped as to hold the arm in vertical position with a portion 36 thereof in firm engagement with the bottom of a slot 37 in the member 17 thereby assisting in the prevention of rattling or vibrating.

The plate 13 attached to the door 11 carries the grooved part of the dove-tailed conneetion 38 (Fig. 4-) between the plate and a bracket 39, the base of the bracket 39, being large enough to cover and conceal the screws let for attaching the plate 13 to the door 11. After the members of the dove-tail are engaged a screw a0 is put in position to prevent disconnecting the bracket from the plate. The screw 4-0 may, as previously mentionet in connection with the screw 21, haveits head beaded with solder after it is in position so as to increase the dil'l'iculty oi removing the screw.

The bracket 39 carries at its outer end a cylindrical member :41 in which is slidably mounted'a bolt 42, The cylindrical portion is'provided with two cam slots a3 and n to accommodate theshai't of an operating handle or knob a5 riveted in the bolt l2. T he construction of the cam slot 4C3 is such that it the handle 45 is operated to and fro in the slot the bolt will be given a reciprocating vell as a rotary motion. The slot 4% will act in the same way, but is only provided so that the same bracket 39 can be used in connection with a door opening at the right-hand side or in cases where, for some reason, it might be desirable to mount the bolt on the door jamb instead of upon the door.

The bolt L2 has a reduced portion 47 of sutliei'ent diameter to en age rather closely wit the slot 35 in the arm or link 24;. The slot 35 has a widened portion 51 which is preferably circular in shape and of a diameterwhich is only a little greater than a head 52 oi the bolt In order to engage the bolt with the slot 35, it is necessary first to close the door and then swing the arm 24 to pass the circular opening 51 over the head52 of the bolt, after which movement of the door will cause engagement of the reduced portion 4.7 of the bolt with the slot 35. After the door has been moved to the desired position the handle 45 is operated, therebycausing the bolt 42 to be moved enawise to clamp thev material, although it is of course advantageous to use materials which cannot easily be cut or bent by someone who is attempting to burglarize a room.
