Specification of Letters Pate'nt.

Patented Feb. 27, 1912.

Application filed January 8,.1912. Serial No. 670,043.

-1'0 a] Z whom it may concern:

and more particularly to fastening means for doors of barns, sheds and similar out side buildings. However the device may be applied to any door, gate, window or like structure.

The invention has for one of its objects, to make a bolt which cannot.- be pulled straight out of the keeper and which can not be readily opened by any one not familiar withthe combination of the device.

Another objectis to produce a simple and inex ensive device having few parts, which are .urable and not aptto get out of order.

Other objects and novel features of the invention will be apparent from the following description taken in connection with the drawings, in which,

Figure 1 is a perspective view ot'the device applied to a door showing the same unlocked; Fig. 2 is a horizontal plan view showing the bolt in its extreme and locked position in the keeper; Fig. is a sectional View along the line 3-3 of Fig. 4, with the top member of the keeper remqved and turned-up; Fig. 1 is a sect-ional vi w along the line 4-4: oflFig. 1 looking in t e direction of the arrows showing the bolt in position; Fig. 5 is a sectional view along the line 55 of Fig. 4looking in the direction of the arrows, the bolt being removed. 1

Referring to the drawings I provide two members, one of which may lie-secured o the door -8 and one to the door casing 9 or they may be applied to two hinged doors.

-On'e of the said members constitutes a gui ling device for the bolt and the other constitutes the keeper. sists of a base 10 adapted to be secured to either the-door 8' or the casing 9 by means of provided with two upstanding parallel cars 12, each of which has a slot 13 adapted to receive the bolt l-L-"lhe bolt 14, consists of a single circular bar of metal and is bent at right angles at the end andsquared ofl'lo form a projection or tongue 15 which engages in the keeper to lock the two. members together. The bolt 14 is also provided with The guiding device con- The base 10 is a knob or'lhumb piece 16 which is preferably provided with a screwthreaded extremity \vherhby it may be removed so that the bolt may be taken out of the guides or ears '12. T he knob 16 is secured to the bolt 14- at a sufficient distance from the projection 15 to permit the latter tomove to its extreme position in the keeper. The knob 16 also constitutes a stop for the bolt 14 when sliding backwardly and forwardly in the.

ears .12. It is to be understood that the bolt 11 is of sufficient.length to be at all times held by the guide members 12.

The keeper consists preferably of two independent members 17 and 18 inclosed within a casing which latter is provided with a keyway 20 adapted to receive the tongue 15 and bolt 14. Thecasing is preferably of a single piece of metal or a singlecasting, as isclearly shown in Fig. 4, and consists of a base portion 20 and an outwardly overhanging portion 21. The'base portion 20, a

part of which constitutes one side wall of the casing, is provided with bolt holes 22, whereby the casing may be secured to a building or other structure by any suitable fastening means, as the screws 23. The overhanging portion 21 constitutes the top and other side wall of the casing and is provided to exclude moisture from the interior of the ame.

In assembling the keeper the member 17 I is first positioned in the casing with its smooth side abutting against the inner top wall thereof and the member 18 which constitutes the bottom wall of the casing is then secured against the member 17 by means of the screws 19, rivets or any similar fastening means. It will be noticed that the members are designed to be assembled before securing the casing to the building and the heads of the screws 19 being on the inside, will be inaccessible to any person s 100 unauthorized to take the keeper to pieces.

While the casing and member 17 are 'shown as two separate elements, it is to be understood that-the two may be, cast in a single piece but I prefer to use the construction as shown because'it is then possible to utilize difierent combinations with the another. To acopmmodate he body of the pite unlike' one the combination may be varied and that bolt 14: a central passageway 24 is provided in the member 18 and leading therefrom are other recesses which, cooperating with the recesses in themember 17, constitute an inde pendent tortuous or irregular passageway surrounding the passageway 24. This irregular passageway is of suflicient width and depth to receive the projection or tongue 15 therein and the latter is adapted to engage any one of the shoulders -formed by the walls of the recesses leading from'the passageway 24 and is thereby locked at various points in its projected or partly retracted position.

The operation of the device Will be clear from the foregoing description. The bolt may be opened. b one who is familiar with the combination y simply turning the bolt 14 by means of the knob or thumb piece 16 and at the same time retracting or projecting the same, whereby the tongue 15 will move through the tortuous passageway past the projections forming the same said passageway.

It will be understood that the details of therefore I do not wish to be limited to the precise details as shown.

What I claim as new and desire to secure by Letters-Patent is,

1. In a device of the class described, the combination of a bolt having a projection thereon, akeeper having a longitudinal passageway in which the body crow bolt may be moved, and an irregular passageway surrounding the longitudinal passageway adapted to receive the projection of the bolt, means for concealing said projection and passage-ways from view when in 0perative relation, and means cooperating with the projection to lock the bolt in the keeper.

In a device of the class described, the combination of a keeper comprising cooperating members, one of said members having a longitudinal passageway provided with recesses in the walls thereof, another member fitting against the first named member and provided with recesses to co operate with the recesses in the first mentionedmember to form a tortuous passage waysurrounding said longitudinal passage Way, a bolt provided with a tongue and adapted to be projected into the keeper, said tongue adapted to engage the walls'of the recesses to lock the bolt in the keeper.

3. In a device of the class described, a 'door casing and a door, a bolt provided with a tongue adapted to slide laterally on the door, a keeper on the casing to receive the bolt, said keeper having a longitudinal passageway and a tortuous passageway, the passageways communicating one with the other, means for concealing said passage ways from View, the body of the bolt adapted to reciprocate in the longitudinal passageway and the'tongue on said bolt movable in said tortuous passageway and means cooperating with the tongue to lock the bolt in. the keeper. v

In testimony whereof I allix my signature in presence of two witnesses.
