' To all whom it may concern:

Be it known that 1, CHARLES F. K0111. BERGER, a citizen of the United States, residing in New York city, in the county of Bronx and State of New York, have invented certain new and useful Improve is to provide a construction particularly adapted for a latch in which the bolt of the latch may be extended in looking position, which bolt is resiliently extended and equipped with the usual bevel end which, when it engages thestrike of the latch, will recede and after having passed such strike will immediately spring out again, which construction has a means for protecting such bolt from being tampered with when the door to which it is attached is locked, with the intent to retract the same.

A particular use for this latch is that it may be used on a small swinging door that may behung on a larger sliding door, or it may be attached to the end of a series of collapsible doors, and in either case it would act as a lock to the entire outfit as well as a latch to the end door. o

A further object of the invention is to provide a means for preventing the members with which a bolt is operatively connected from being xpried apart, or far enough apart to obtain access to such bolt.

Still another object of the invention is to provide a protecting means for a latch as above set forth, which protecting means is particularly simple in construction, easy to manufacture and can be produced at comparatively low cost.

integral with a part of the housing of such .latch and thus does not contemplate the making of any extra parts.

A particular feature of the invention is that the extending portion of the protecting and securing means is attached entirely to the lock casing rather than to the strike and Specification of Letters Patent.

Fig. 13 is a fragmental perspective showing the recess of the latch of the modification shown in Figs. 11 and 12.

In the embodiment shown, the strike comprises a housing member 11 having a flange 1 to accommodate the securing means for securing the strike to the door frame F. The

w members

18, 18 unite with the

narrow wall members

20, 20 which extend at right angles to the wall members 18 and have an intermediate wall member 21 disposed between said

wall members

20, 20 which wall members and 21 are disposed parallel to the side 13 of the frame F and form another wall portion of the housing 11. The upper and lower wall portions and the wall portion parallel and opposite to the wall gomembers l8 and 19-are continuous and closed members while the side 13 of the door frame F preferably, as illustrated, forms the remaining wall portion for the housing 11.

The part of the latch which is attached to the door D to cooperate with the strike preferabl comprises a trough-shaped portion 22 having a flange 23 by means of which it is secured to the door D, the flange 23 having screw openings 23 therein to receive secur- 3 ing means for securing the portion 22 to the door D and the exposed or open side of the trough-shaped portion 22-being closed by the side 21 of the door D when so attached to such door. The side 25 of the troughshaped portion 22 is preferably disposed in a plane with the side 26 of the door in which side 25 an opening 27 is provided through which protrudes the bolt 28 and the bolt protecting member 29 which latter are both connected inside of the trough- "haped portion 22.

For securing the trough-shaped portion 22 to the door D, the flange 7' as illustrated in dotted lines in Fig. 2.;may be provided extending at right angles to the flange 23 and adapted to be disposed in a recess specially formed for it in the door D.

The protecting member 29 preferably comprises a flat bar 30 to be secured to the door D inside of the trongh-shaped portion 22 and forming a wall portion for the channel formed in said trough-shaped portion 22. The protecting member 29 extends out of the channel of said trough-shaped portion 22 and beyond the side 25 of such portion. The portion of the protectlng member 29 extending from the trough-shaped portion 22 15 provided \"llll two wall members 31 "which extend the full length of the pro- 80 tecting' lm'ember 29 which protrudes from the portion and extends at right angles from said fiat bar 30 to the side 32 of the opening 27 which side 32 is parallel with the side 24 of the door D. The side 33 of the protecting member 29 is provided with a recess 34 extending from one side to the other side of the protecting member 29 and in length, preferably commencing at the face 25 of the trough-shaped portion 22 and extending to within a short distance of the outer free end of the protecting member 29, the side of the recess 33 nearest the free end of the protecting member 29 being convex as shown at 35 (Figs. 4 and 5) to allow for sagging of the door.

The bolt 28 is disposed in the channel of the trough-shaped portion 22 and extends out of the opening 27 having a portion of it disposed between the wall members 31 of the protecting member 29, which bolt 28 is provided with a beveled end 36, the inclined face of which faces the side 13 of the door frame F. lVhen the bolt is extended in its locking position, the beveled end 36 of this plate will extend out beyond the edge 37 of the intermediate wall 21 of the housing 11 when the door D is in closed position as shown in Fig. 8 This bolt 28 as usual is resiliently extended in such outward locklng position by means disposed in the trough-shaped portion 22 and which are controlled and operated by the pin 38 and the thumb screw 39 in the Well known manner. The protecting member 29 is also provided with an opening 40 in which the extension 41 (Fig. 4) is disposed, the door D being provided with a suitable opening 42 to permit a key to be inserted into such extension 41. The walls 31 may further be provided with a Wall member either in: tegral or separate which will extend from one free edge to the other free edge of such walls 31 and will completely inclose the bolt 28 from access thereto when the door D is disposed in closed position. This wall member may also be integral with the side 25 of the portion 22. In the present instance, a wall member 43 (Fig. 3) is provided which is secured to the edges of the wall members 31 having one edge of it disposed snugly against the face 25 of the portion 22, and its opposite edge slightly beveled which opposite edge will be disposed ad ace1it to the edge of the intermediate wall 21 when the door is in closed position.

When the door is closed as shown in Fig. 8, the intermediate wall 19 will be disposed in the recess 34 so that the portion 14 of the protecting member 29 will extend toward the side 13 of the frame F, the beveled face of; the beveled end 36 of the bolt. 28 will face the side 13 of the frame F and its end will be disposed inside of the edge of the intermediate wall 21, such wall 21 forming the obstruction which cooperates with the end 36 of the bolt 29 to lock the door.

The protecting member 2 will prevent access to, or a tool that has been inserted between the door D and frame F from the outside of the door, from coming into contact with, the bolt member 28 to retract the same. Furthermore, the portion 44: of the protecting member 29 will act as a stop which, coacting with the intermediate wall member 19, will prevent the door D from being pried from the frame F by a tool such .as a jimmy in order to jam the door so that the bolt 28 would clear the portion 21 of the strike 11 without being retracted, or to even reach the bolt member 28.

In the modification shown in Figs. 10 and v 12, the strike is substantially identical with that illustrated in Fig. l, with the addition that the intermediate low wall member 19 is provided with an elongated lug 45. The

. latch of the modification shown in Figs. 11

and 12 is substantially identical to that illustrated in Fig. 2, with the exception however that the bar is provided with a recess 46, instead of the recess 31, which recess 46 does not extend completely across the protecting member 29, but terminates a short distance from each side of said protecting member 29.. By means of the modification illustrated in Figs. 10 to 13 inclusive, an

arrangement is provided whereby no hook portions such as the hook portion 44 (Fig. 9) are exposed, on to which portion, the loose flowing garments of a by-passer might catch.

It is obvious that various changes and modifications may be made to the details of construction without departing from the general spirit of the invention.
