REVERSIBLE LOCK-CASING AND KEEPER FOR COIN-CONT-ROLLED LOCKS.

Original application No. 83,820, filed March 13, 1916. Divided and this application Serial No. 109,126.

To all whom it may concern:

Be it known that I, GEORGE G. F. BOSWELL,-

and exact description thereof, reference being had to the accompanying drawings, in which like letters refer to like parts.

The invention set forth in this application for Letters Patent relates to reversible lock cases and keepers and covers subject matter divided out of the former application of the applicants, Serial #831,820, filed March 13th, 1916.

The object of this invention is to construct a lock case and keeper in such a way that they will be reversible, and arrange the parts so as to prevent the bolts of coin controlled looks from being picked. This object is ac complished by having a flange extending from the lock case so as to project over or overlap the keeper into which the lock bolt enters when thedoor is closed. This prevents the picking of the look by inserting an instrument between the keeper and the 1loorik case into the lock to move and open the The full nature of the invention will be understood from the accompanying drawings and the following descriptlon and claims.

In the drawings, Figure 1 is an elevation of a portion of a door and door frame with a coin controlled lock thereon and the door closed, the lock being at the left-hand edge of the door. Fig. 2 is the same with the lock reversed and placed at the right hand edge of the door. Fig. 3 is a central vertical section through the lock. Fig. 4 is a cross section through the lock and bolt showing the case overlapping the keeper so that the door may open outward. Fig. 5 is the same as Fig. 4 only reversed so that the door may open inward instead of outward and the keeper overlap the case. Fig. 6 is a detail perspective view of a portion of the lock frame. Fig. 7 is a sectional View thereof on line 77, Fig. 6.

There is shown in the drawings in Fig. 1 a door 10 with a lock on the left-hand edge thereof engaging a keeper 11 on a part of the door frame 12. v In Fig. 2 the lock is at Specification. of Letters Patent.

the right-hand edge of the door instead of the left. The lock casing 13' consists of a single case forming the front, sides and top and with the back open and adapted to be secured to the door so that the door closes the back of the casing. None o'f the mechanism is mounted on the door, but instead it is all mounted in the casing so that when the casing is removed, all of the lock mechanism is mounted in-connection with that one part of the casing instead of being mounted 011 a plurality of parts of the casing, as heretofore. This enables the lock mechanism to be rigidly mounted and be accessible for repalrs or manipulation.

The casing has an operative flange 14 on both sides thereof which surrounds, envelops and overlaps the inner end of the keeper so that when the door is closed and looked, a person cannot insert any instrument between the keeper and the case and thus get into the lock and move the bolt to open the same. The flanges on both sides enable the casing to cooperate with the keeper and to accomplish this end whenever the lock is reversed regardless of the position in which it may be mounted. A modified form is shown in Fig. 5 where there is a flange 15 on the outer portion of the keeper 11 instead of a flange being located on the outer part of the casing. The purpose of this construction is to adapt the lock to the door if it swings inwardly. The construction previously described and shown in Fig. 1 is adapted for a door which swings outwardly. It is immaterial whether the flange .14 for protecting the look from picking projects beyond the main surface of the case or not so long as there is a surface of the case which overlaps the keeper.

The case has a counter slot 16 in its upper end, a coin inlet slot 17 below it, a porter key hole 18, an outside knob 19, a removable door 20 and the coin chamber, as shown in Fig. 1.

There is shown in Fig. 4: a bolt 25 which has a vertical and longitudinal slotted portion 26 extending almost to each end thereof and wide enough to receive any of the small coins. The bolt is slidable transversely of the casing between the two guide ribs 27 and 28 which extend entirely'across the inner surface of the front wall of the casing. On each side of said bolt there are two flanges 30 and131 and said flanges on the.

two sides of thebolt are opposite each other respectively, as shown in Fig. 4. The rear flanges 30 have each a hole through which a guide rod 32 loosely projects. The rod 32 is connected with a plate 33, said plate being adapted to close the bolt opening 34 of the lock casing 13 not occupied by the bolt. The plate 33 is prevented from assing outwardly through the opening 34 by inserting a plate 35 over the opening 34, said plate 35 having beveled ends which engage dovetailed recesses 14 formed in the end walls of the flange 14. After the plate 33 carrying the rod 32 hasbeen properly positioned in one or the'other of the bolt openings 34, the plate 35 is entered in the dovetailed grooves of the member 14 and when the casing has been attached to the door it will be impossible to remove said plate 35 until the casing is disengaged from the door. From this construction it will be seen that the flange 14 not only serves to prevent the lock from being picked by introducing an instrument between the keeper and the casing, but serves as a retainer for'the cover plate for the bolt opening not in use, and that said cover plate can be used at either side of the lock casing. A spiral spring 36 surrounds the rod 32 and bears against the flange 30 for throwing the bolt and holding it in looking position. Said spring is compressed when the bolt is retracted. Both flanges 30 have a hole in them to receive'said rod 32 so that the bolt can be reversed, as shown in Fig. 5, depending upon whether the. door is to move outward, as shown in Fig. 4, or to move inward, as shown in Fig. 5.

On the front face of the lock case surrounding the slot 17 is a coin measuring frame having on one side thereof an openthe lock is removed whereby a coin of a oer-- taln denomination only, may be inserted through the slot 17.

The invention claimed is: I

1. The combination with a door frame, and a. door, of a keeper'on the doorframe,

a lock on the door having a bolt adapted to enter said keeper, acase with a bolt opening on the opposite sides thereof, and a flange.

surrounding each of said bolt openings so 4 as to overlap the keeper on its top and bottom faces and its outer face, substantially as setforth.

2. The combination with a door, of a lock casing, consisting of a single member open at the back and secured to the door, said door acting as a back plate for the casing, said casing having a bolt opening on opposite sides thereof, a flange extending around three sides of said opening, and means 00- operating with said flanges to close either bolt opening.

3. The combination with a door frame and a door, of a lock casing having a bolt opening on opposite sides thereof, a flange extending around three sides of said opening, each flange having dovetailed grooves and a plate having beveled ends for cooperation with said dovetailed grooves adapted to cover either of said bolt openings.

In witness whereof, I have hereunto affixed my signature. I

GEORGE G. F.'BOSW'ELL.
