COIN-CONTROLLED LOCK.

Application filed February 19, 1923. Serial No. 619,960.

T 0 all whom it may concern:

Be it known that I, FRANK MoDnNrnL, a citizen of the United States,-residing at Detroit, in the county of Wayne and State of Michi an, have invented certain newand useful finprovements in Coin-Controlled Locks; and I do declare the following'to be a full,.clear, and exact description of the invention,csuch as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to improvements in coin-controlled locks of the type used for instance upon lockers one object being to provided novel means for holding the bolt of the lock against operation in case an actuator which is associated with said bolt, is. moved Without inserting a coin to establish a connection between the actuator and bolt to permit operation of the latter, 1

' A further object is to provide a novel form of bolt and actuator of such construction as to permit the edgewise insertion of atom to form. an operating connection between them- I lVith'v the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, the de scription being supplemented by the accompanying. drawings.

Figure 1 is an inner side elevation of .a lock constructed in accordance with my invention, showing the normally unlocked condition thereof. 1

Figure 2 is a duplicate of a portion of Fig 1 with the exception that it illustrates the locking bolt projected.

Figure 3' is a view similar to Fig. lflbut illustrating the relation of parts when an attempt is made to project the bolt without inserting a coin.

Figure 4 is a horizontal sectional view as indicated by line 4.-4 of Fig. 1. Figure 5 is a vertical section on line. 5-5 of Fig. 4:.

F'gure 6 is a vertical transverse sectional view on line 6-6 of Fig. 5.

Figure 7 is a perspective view of the bolt and the tumbler which normally prevents projection of said bolt.

Figure 8 is a perspective view of the bolt actuator. c

In the drawings above briefly described, I have shown a vertically positioned channel-shapedplate 1 which may either be a flange 20f the plate 1 has" been shown as f r ed with an pe ng 3 ug Which the bolt 4 which is horizontally guided in any suitable manner may be projected. In. the preferred form of construction, this bolt is of the formation shown most clearly in Fig. 7. In this view, the bolt is shown of channel-shape, being provided with a bottom 5, a comparatively long side wall 6 adjacent the plate 1, and a relatively short side wall 7. A lug 8 extends laterally from the sidewall 7 and alsogextends downward 1y from the bottom 5, the two side walls and said bottom beingslotted as indicated at 9 to receive a coin 10. This slot opens through the lower side of the lug 8 and while it opens through the upper edges of the, two side walls 6 and 7 and through the wall .6, it does not open through outer. side of the laterally extending part tance into said lug.

.Slidably received in the channel of the bolt 4 is a horizontally elongated bolt, actuator ll having a slot, 12 which normally registerswith theslot 9 to receive the coin 10, when the latter is inserted edgewise through a slot 13in the plate 1. i For-operating the actuator 11, I have shown a commonform of cylinder lock 14 having a projecting finger 15 received in a recess 16 in theupper edge of said actuator. a The construction. (well known) is such that when the key is inserted into the lock 14 and turned to cause I'Qt-laClLlO'fl of the bolt 4 and its actuator 11, the key is locked in place and cannot be removed. When a coin 10 is inserted however in the registering'slots 9 and 12 and the lock 14 a is actuated by means of the key to project the bolt, thenthe key canbe removed, leaving the door locked in closed position. When it is desired to again unlock the door, the key'is inserted into the lock and the latter is turned to move the actuator 11 in the proper direction for withdrawing the bolts. iWhile any suitable connection may be employed between the actuator and bolt for this purpose, I have shown said actuator provided with a depending stud 17 reof the lug 8, althoughit extends some disceived slidably in a slot 18 in the bottom 5 of the bolt 4. While this connection operates to retract the bolt, the stud will merely slide within the slot if an attempt is made to project said bolt Without first inserting a coin to establish an operating connection between the actuator and bolt.

In the preferred form of construction, the bolt 4 rests slidably upon a suitable plate 19 secured by screws or the like 20 to the plate 1, this plate being here shown as provided with an annular flange whosehorizontal portion 21 constitutes a ledge normally underlying the registering slots in the bolt and actuator Thus, when a coin is inserted in said slots as shown in Figs. 1, 5 and 6, this coin will be supported by the ledge 21. When the lock 1A is operated to bodily project the actuator 11 of the bolt 4 hswever, the coin is moved from the ledge and drops into a suitable receptacle (not shown) as will be clear by reference to Fig. 2.

It will be seen from the foregoing that the actuator 11 may be idly moved within the channel of the bolt 4 when no coin is inserted into the device, but to positively prevent'projection of the bolt A by such idle movement, I provide normally idle boltholding means which is moved to an operative position by projection of the actuator within the bolt, to a predetermined extent. In the present showing, this means is in the form of an annular gravity-released tumbler 25 loosely pivoted at 26 to the side wall 6 of the bolt, beyond the lug 8, so that the depending arm 27 of this tumbler, is in the outward path of the actuator 11. The horizontal arm of the tumbler 25 is so disposed that when said tumbler is tilted by outward-' movement of the actuator, said arm will engage the flange 2 as shown in Fig. 3, thus holding the bolt against projection, unless a coin is inserted. Upon the insertion of this coin however, relative movement of the bolt and actuator is prevented and they are caused to move bodily as a unit and consequently the tumbler 25 will not come into lay.

Preferably used in connection with the features above described, is a suitable counter 30 which registers the number of times the bolt is projected. I also prefer to provide this bolt with a depending V-shaped lug 31 engageable with a spring arm 32 when the bolt is projected, preventing accidental release of the latter.

From the foregoing, taken in connection with the accompanying drawings, it will be seen that I have provided a simple and inexpensive, yet a'highly elficient and reliable lock which may only be operated by the insertion of a coin. Particular attention is directed to the fact that the construction is such as to permit edgewise insertion of the coin as experience has proven that the coin is much easier to insert in this manner than when it must be moved bodily into a circular opening. Attention is also directed particularly to the novel means employed to prevent accidental projection of the bolt by idle movement of the actuator.

As excellent results have been obtained from the details disclosed, they may be fol lowed if desired. However, within the scope of the invention as claimed, numerous minor changes may be made.

I claim:

l.'A coin-controlled lock comprising a bolt, an actuator for said bolt movable with respect thereto, said bolt and actuator having spaced shoulders between which a coin may be inserted to operatively connect said bolt and actuator, and normally idle means brought into play by movement of the actuator with respect to the bolt for holding the latter against projection.

2. A coin-controlled lock comprising. a bolt, an actuator for said bolt movable with respectthereto, said bolt and actuator having spaced shoulders between which a coin may be inserted to operatively connect said bolt and actuator, and a normally idle boltholding tumbler carried by said bolt and having a portion in the path of said actuator formoving said tumbler to operative position upon'movement of said actuator with respect to said bolt.

3. A coin-controlled lock comprising a bolt, an actuator for said bolt movable with respect thereto, said bolt and actuator having spaced shoulders between which'a coin maybe inserted to operatively connect said bolt and actuator, and a gravity-released normally idle tumbler pivoted to said bolt and having a portion in the path of said actuator, whereby idle movement of said actuator with respect to the bolt will move said tumbler to an operative position at which it prevents movement of said bolt.-

l. A coin-controlled lock comprising a channel-shaped horizontal bolt and guiding means therefor, a lug extending laterally from one side and downwardly from the bottom of said bolt, the side walls of said bolt and its bottom having a coin-receiving slot which opens through thelower side of said lug and extends into the laterally extending part of said lug, a bolt actuator slidable freely in said channel-shaped bolt and having a slot which opens through its vertical sides and its lower edge, the slotsv of the bolt and actuator being normally in register to receive a coin, and a fixed ledge under said lug upon which the coin rests when inserted, movement of the actuator and bolt upon the insertion of a coin serving to move the latter from saidledge.

5. A coin controlled lock comprising a channel-shaped horizontal bolt and guiding means therefor, a lug extending laterally from one side and downwardly from the bottom of said bolt, the side walls of said bolt and bottom having a coin receiving slot 5 which opens through the lower side of said lug and extends into the laterally extending part of said lug, means for supporting a coin inserted into said slot until the bolt is projected and a bolt actuator slidable in said channel-shaped bolt and adapted to en- 10 gage a coin in said slot to project said bolt.

In testimony whereof I have hereunto aflixed my signature.
