DAVID WILSON WOID, 0F ZEIMLZUL, INDIANA..

G01N-communi) Loonspecification f Leiters' Patent.

To all whom` 'it fmay concern:

Be it known that I, DAviD citizen of the United States, and a resident otBLi-azil, inthe county ofClay and State of Indiana, have invented a new and 1inproved Coin-Contrelledf Lock, of 'which the .following a itull, clear, and exact description.4

My invention relates to a coin-controlled lock, andmore particularly .relates to. locks .on doorsto rooms,to enter which rooms a charge is made.. j

'An object of my invention is to provide a lock-.of the above indicated character, in

which the coin will remain in view ater4 the door is unlocked and will remain in this Vposit-ion until the door is opened from the inside.

A further object of my invent-ion is to:

providea lock of the above-identified chafre act-er in which it will b e possible to openthe door from the -ins'ide but once'after each coin inserted. l

A further object ot;` my invention is to provide a mechanical means for registering the number of times the unlocking device is actuated.

A further object of my invention is ,to provide a lock of the above indicated character'in which it is not possible to insert a second coin'until the door is in position to admit a second occupant.

A further object of my invention is to provide means whereby the door may be closed by gravity 'without slamming or without retracting the bolt of the lock( I attain the above outlined objects by positioning within the lock casing, a bolt normally in projected position, which is locked in such position by an actuating locking lever, said locking lever actuated by a coin which permits the outer knob to actuate the y bolt, which bolt is also actuated by an innerknob, the actuation by said inner knob causinga punch to perforate a roll of paper, and, at the same time, to'disengege said lever from its locked engagement with the bolt and to withdraw the bolt, to permit the door to be opened from the inside. I

further provide a catch--holding means on the frame ofthe door, which permits the bolt while in projected position, to engage the means on the frame of the door without actuating the bolt.

With the above and other objects inl view as will more `Fully hereinafter appear, the

W. Woof),

'Application filed December 2, 1911. Serial No. 663,599..

present inventionconsists in certain novel details vof construction and arrangement of parts hereinafter fully describe-d, illustrated in the accompanying drawings, and more .particularly pointed out in the appended claims.

Reference is to be had to the accompanying drawings, forming a partent this specitication, in which similar characters of reference indicate corresponding parte in all the figures, and in whichl Figure 1 is a side elevation of the lock and holding means with'the back of the nism and with the bolt in locked position; .-Figx 2 is a View similar to Fig. 1 but shoning the bolt in retracted position; Fig. 3 is a transverse sectional view taken on the line 3-3 of Fig. 1; Fig. 4 is an enlarged perspective viev7 of the locking lever; Fig. t3 is a similar View of the bolt'. Fig. 6 a trans verse sectional view showing the punching device, and Fig. 7 is a fragmentary side elevation of the locking lever and bolt, viewed from the side opposite that shown in 1 and 2.

As shown in the drawings, there is mounted upon a door A, a lock B more par .invent-ion, the bolt of which is adapted to engage a ratchet catch C mounted upon the frame of the door. The lock B comprises a ing from opposite sides of 'which casing is an actuating inside knob 8 passing through the door A, and extending in the opposite direction from the casing is a separate out side knob 9. Within the top of the casing T whichl coin slot is a substantially L-shaped lever 11 pivo ed intermediate its length at 12, to one side of the casing and so disposed relative to the slot 10, that a coin 13 inof the lever 11,- swinging the opposite slotclosing end 15 into position, as shown in dotted lines-in Fig. 1, closing the slot 10. The coin in the position shown in 'dotted side of the'casing B, and a partition 1G spaced from said wall a distance substantially equal to the thickness of the coin in sorted. The coin rests uponthe end 17 oi a the aperture 19, and has extending trom casing removed to show 'the internal mocha ticularly forming the subject-matter of this f casing 7 of any suitableconstruction extend is a coin slot 10 disposed in the path of i serted in said slot will fall on the portieri lat,

lines in Fig. 1, is contined between the inner locking lever 18, which is fulcrumed by supf porting the same on a pin extending through l lateral sides and. on. the end adjacent the end receiving the coin, a latch 20, which latch normally rests in a pocket 21 on the top of and to the rear of the locking bolt 22, which locking bolt. is disposed to one side of and parallel with the locking lever 18 and eX- tends through a recess on the front edge of the casing 7, to engage with the locking member on the fra me hereinafter described. As shown more particularly in Fig. 2, this coin-raising member 18 'disengages the latch 20 from the pocket 21,V so that by rotating the spindle 24- by turning the knob 9, a stud 25 rigidly mounted'on the knob shaft permanently engages a recess 26 in the side of the bolt 22, said bolt beingactuated, throws the same into the retracted position shown in Fig. 2, permitting the door to be opened. The movement of the lever 18 is limited by means of a pin 2T mountedon a bracket 28, the head 2.() of which pin is disposed beneath the end 17 and is maintained in this position by means of a coil spring 3U having one end bea ring underl the head 29 and the opposite end resting on the bracket 28.

Mounted in the rear of the casing and in rear of the bolt 22, is the recording device, comprising a pair .of drums, the lower drum 3l being mounted on standards projecting from the bottom of the casing 7 and the Lipper drumI 33 havingrigidly aflixed to one side thereof, a ratchet wheel mounted on a pin 35 projecting from the rear face of the casing. Pivotally mounted to the rear side of the bolt 22 and positioned below the inner end of the locking lever 18, is a pawl 36 adapted to engage the teeth on the ratchet 34. The under side of the pawl is adapted to' be engaged by a transversely-disposed pin 3T projecting from one side of an. olfset projection 38 mounted on the side of the lever opposite the bolt 22.

lith the bolt in the above position, a person may pass into the room closing the door behind him, thus throwing the bolt outwardly and causing the same to engage Within laterally disposed recesses in the sides of a cylinder 4() pivotally mounted Within a casing 41 on a stud 42, Which casing is suitably mounted on the frame of the door. The to'p of the cylinder 40 has formed thereon radially-disposed one-way ratchet teeth 43 engaged by a paivl 44, which pawl is mounted on a suitable boss within the casing 41.

lt will beseen by this construction. that the bolt when in its projected position, swings in the direction of free movement of the cylinder 40 and engages the recess 39 in its path, rotating the cylinder 4() until the recess is in line with the bolt. rl`he door, -of course, cannot be opened Without withdrawing the bolt, as the pawl 4-1- prevents the cylinder from operating in the direction to open said door. The bolt maintained in its pro- 7, is a bracket 48, the bearing 49 of Which cam bears upon the under side ofthe locking lever 18, raising said locking lever a distancesutiicient to permit the coin to drop into the lower portion of the casing 7, and, at the same time, disengages the latch 20 from the pocket 21 and permits a linger 50 positioned Within a recess 51 on the side of the bolt 22 and rigidly maintained on the shaft 52 carrying the knob 8, to bear against the rear Wall of said recess to Withdraw the bolt.

Mounted inthe rear of the shaft 52 and positioned from the rear side of the casing mounted Within which is a sleeve 54 having a pocket 55 in the rear thereof, the rear open end of which pocket is closed by a seresT cap 56 bearing on one end of a spring 57 Within said recess, the opposite end of which spring bears upon a punch 58. The point :fof this punch is adapted to perforate a roll of paper 60 mounted upon the drums 31 and Adapted to bear upon the head 56 is a finger lrigidly mounted lupon the shaft 52. It will be seen that by this construction, the retraction of ,the bolt in opening the door, will cause the linger 6l to press the point 59 into the paper, causing the same to be perforated, and thereby registering the number o't actuations of the'bolt. The pawl 3G moves the ratchet 34, bringing the roll of paper into position, to receive the perforation. Opening the door by means of the inside knob, perfor-atea the paper, and opening the door by means of the outside knob, causes the pawl 36 to more the ratchet wheel 34, bringing the roll of paper into position to be again perforated by the punch 38.

rl`he cam 48 has a quadrant-sliaped slot 62 within which is positioned a pin G3 rigidly mountedl in the side of'tbe easing, which permits the limited movement of the cam, and a spring 134 haring one end attached t'o the cam and the opposite end attached to the bottom of the easing, positions the cam in its initial position when pressure is Withdrawn from the knob 8; a projection 65 eX- tending from the periphery of the cam 48, engages the curved recess 6G j Within the. under side of the locking lever 18, preventing` the actuation of the,bolt until'a coin is inserted to raise the lever 18. When there is no coin on the lever 18, the end of the cam 48 engages in the curved recess 66 andstnps the actuation of the bolt 22. When a coin is dropped into vthe box, it raises the lever 18, so that the end 17 will drop on the hrad raising therecess to. clear the end of the cam 48, and the projection 65 engages the under side of the lever 18, raising it so that the end 17 will drop low enough to permit the escape of the c'in, and, at the same time, disengages the pawl 36, permitting the ratchet 34 to remain stationary. y

Should it be desired to unlock the door without the necessity of i-nserting a coin, there is provided a keyhole 6 7, permitting the insert-ion. of a key to engage a stop 68 on the topl of the locking bar 18 and to one side of t e keyhole, so that the key will press on this stop to raise the locln'ng bar, as shown in Fig. 2.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:
