2 Claims.

This invention vrelates to latches especially adapted for swinging doors and has for the primary object the provision of a device .of the above stated character which is simple and prac 5 tical in construction and may be easily and their mode of operation being located 4on theY pull or push for operating the ultaneously act to swing the door so that the handles will si door open.

With these and other objects in View this invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawing, in which Figure 1 is an end elevational view showing parts of the latch in dotted lines.

Figure 2 is a plan view illustrating the latch.

Figure 3 is an end View partly in section illustrating the device.

Figure 4 is a perspective View illustrating the latch bolt.

Referring in detail to the drawing, the numeral l indicates a fragmentary portion of a swinging door and the character 2 indicates a fragmentary portion of a door frame having a keeper 3 being engaged by a latch bolt 3 constituting a part of my invention. The door l is recessed or slotted for the reception of a casing 4, thevlatter being secured to the door by screws or like fasteners 5. The casing i preferably comprises side plates 6, an end plate l and a reinforcing plate 8. The casing 4 when applied to the door l has the side plates 6 thereof arranged at opposite sidesV of the door with the end plate l opposite the keeper E. The end plate is provided with an opening 9 to align with the keeper 3 when the door is in a closed position so that the latch bolt slidable in the casing may readily enter the keeper.

The latch bolt 3 is slidably supported in the casing by one of the side walls 6 and the reinforcing wall 8, theflatter having a slot therein to permitv free movement of the latch bolt therethrough. The latch bolt embodies a body l Ihaving laterally extending oifset portions II and l2 carries spaced pins i4 operating through ap- 5 v ertures in the reinforcing plate 8 and surrounding the pins lil are coil springs l bearing against the offset portion i?. and the reinforcing plate 8 to normally position the latch bolt s0 that the head i3 protrudes outwardly of the casing to 10 enter the keeper tl. The lateral offset Il is arranged at right angles to the body ill. The latch bolt is further supported by a member I6 carried by the end wall 'I of the casing, the member it having slidable engagement with the offset portion l2.

Handles il and i8 are provided kfor the operation of the latch bolt, that is, retracting the latch bolt against the spring l5 and away from the keeper 3. tially U-shape providing bight and arm portions. The arm portions extend through openings in the side walls 6 and one arm portion or" each handle is pivoted to the casing, as shown at I9, while the other arm portion carries a pin 2i) limiting the outward movement of said last-named d arm portion from the casing. The arm portion of the handle i8 which is pivoted to the casing enters the substantially U-shaped offset portion i2 of the latch` bolt and has an angularly related end. The pivoted a'rm portion of the handle I1 is provided with an angularly related end engageable with the offset portion Il. A push on k the handle il towards the casing for the purpose of swinging the door open causes a retraction of the latch bolt due to-.the pivotal movement of said lever Il and one of its arm portions in engagement with the offset il of the latchj bolt. A pull o-n the lever i8 toV open the door` causes a retraction of the latch bolt from the keeper by 40 the pivoted arm portion of said lever engaging with the'oiset portion l2 of the latch bolt. It

will be seen that the operation of either of the handles to retract the latch bolt does not affect the movement of the other handle. As soon as either of the handles is manually released, the springs i5 immediately reposition the latch bolt to engage with the keeper on the closingV of the door. The handle il can be employed for closing the door by a pull thereon and the handle I8 may close the door by a push thereon. Either of these operations will no-t impart a pivotal movement to the handles. The construction of this latch is such that its application to a door which swings right or left can be easily made or The handles 'i7 are of substan- 20' l other-words this latch is adaptable to doors Lvnging left or right.

Having described the invention, I claim: y 1'." A latch comprising a casing, a spring pressed Y latch boit sndame in said casing, said casing hav. ing pairsrof openings .in opposite walls thereof, substantially Irl-shaped handles extending through the' openings,` means pivoting the handles to the casing adjacent one endof said handle, pins carried by the other ends of thek handles for limiting the sliding vmoveu'nent ofthe handles rel- Y ative to the casing in one direction, offset portions on the latch bolt, said `pivotedend of the handles engaging the offset portions whereby a bolt i push on one handle will retract the latchV or a pull on the other handle will retract the latch bolt'.

by a push on one of said handles or a. pull on the other handle, and means carried by said handles to abut the casing to limit the movement of the free ends of the handles outwardly of the casing.
