w-awam- COIN-CONTROL SERVICE APPARATUS.

Application filed June 15, 1923. Serial No. 645,655.

To all whom 2'22 may concern:

Be it known that LFnANK J. Rowsn, a citizen of the United States, residing at Pawtucket, in the county of Providence, and State of Rhode Island, have invented certain new and useful Improvements in Coin-Control Service Apparatus, of which the following is a specification.

My invention relates to coin controlled service apparatus and particularly to such devices, commonly known as coin locks, as are described in Letters Patent of the United States No. 1,048,033, dated October 29, 1912, and in my application for Letters Patent of the United States, Serial No. 471,17 2, filed May 20 1921. These locks are used principally in connection with pay toilets, so called.

The purpose of my invention is to provide an automatic mechanicalcheck upon the coins received as compared with the number of times the authorized attendant has entered the compartment. If the attendant is lazy or regardless of his duty, he may omit to clean the compartment and renew its supplies, thus defrauding the patron who has paid for service. On the other hand he may be dishonest and for pay permit others to use his key, thus defrauding the proprietor of the lock. The manner of automatically restricting these frauds by means incorporated in the lock, as well as other improvements are hereinafter described.

The accompanying drawings forming a part of this specification show respectively:

Hereinafter, the following terms have the significance here defined. Coin control is that mechanism through which retraction of the bolt is secured by the interposition of a coin. Coin is the thing prescribed for effecting the retraction of the bolt, whether actual currency or a special token devised for the purpose; except where the term coin may be ex )ressly qualified to indicate something di erent. \Vasher is anything that may be deposited in lieu of a coin with fraudulent purpose. Key control is that device whereby the attendant, inspector or other authorized person gains access to whatever is controlled by the look, without use of a coin: Exit handle is that instrumentality whereby one who has entered a compartment which is accessible through a coin controlled lock, leaves said compartment. Coin carrier is the device which receives and retains the coin, carries it through its functioning period and until it is released and deposited in the coin receptacle at the bottom of the case.

Fig. 1 shows the exterior of my improved coin controlled lock with its case 2, provided with the coin slot 3 leading to the coin control, and keyhole 4 of the key control. The bottom of the interior is the coin receptacle for the deposited coins to which access is gained by removal of the cover 5 which is secured by a key lock indicated by 6.

The bolt 7 is mounted on the back plate to the back plate, pressing against the rear end of the bolt 7, normally projects the latter to engage the keeper 12.

The exit handle 13, shown in broken lines in Fig. 2, is mounted on a hollow shaft or spindle 14 which, on the interior face of the back plate 8, (that face which when the lock is in position constitutes one interior wall) carries a cam 15 which, with other functions, serves to retract the bolt 7. This is accomplished by the lobe 16 which when the cam is turned in the direction. of the arrow K encounters the shoulder 17 of the bolt, propelling and retracting 1t. The bolt spring 11 is anchored midway of its extremities, andthelower portion is so formed as to engagethe lobe 18 of the cam 15, to return said cam and the exit handle connected-with it to normal position.

The coin-carrier is a unitary mechanism mounted, as will be described, upon the shaft 19 which has a bearing 20 at the front .of the case 2 (Fig. 7) and at the rear of the case, in the hollow shaft 14 above described. At the outer end of the shaft 19 is the access or coin operating handle-21.. .lhe.opposite or inner end of the shaft 19 is fitted to bear in the hollow shaft 14 as aforesaid. On the shaft 19 is a cam plate 22 which moves with the shaft 19 only when a coin is deposited in the coin slot. This cam plate controls a projection-23 which, when the cam plateturns with .the shaft, engages the vertical flange 24 of the bolt 7 (Fig. 2). As the cam late 22 turns with the shaft 19 this proection 23 propels and retracts the bolt 7. The cam plate 22 is of a U .or channel formation, each wall having a bearing for the shaft 19, (Fig. 7). The cam plate 22 is mounted on the shaft 19 between the two

side plates

25 and 26 .of the coin carrier, which side plates are maintained at the proper distance apart by

spacing posts

27 and 28 of suitable construction, (Fig. 3 and Fig. 6).

The

side plates

25 and 26 are secured to the shaft 19 by the pin 29 which projects from the shaft between two projections 30-30 on the side plate 26 of the coin carrier (see Fig. 3). The side plate 25, being that adjacent the front of the lock, is formed with an arcuateslot (Fig. 4) con centric with the shaft, through which slot extendsthe projection31 from the cam late which protrudes beyond the face of the side ,plate 25. The latter bears against the hub of the bearing 20 which rises above the inner wall of .the case. Within the space thus provided between the wall of the case and the side plate 25 is a shutter 32 to close the .coin slot 3. The shutter 32 is swung on a ,pin secured :to the ,inner wall of e ca 2.1 m the b a ng 2 .A e ondary coin slot .34 in the shutter 32 nor- ,and .52 (Fig. .1).

mally registers with the coin slot 3 of the case. It is held to such registration by the spring 35 which presses the shutter 32 against the stop 36 on the inner wall -of the case. The spring 35 is held by a member 37 which, besides affording anchorage for the spring 35, also supplies a guide for the coin. It is formed with an inwardly turned and slotted portion, so disposed as to insure the coin being properly directed into the coin carrier. The spring 35 does not engage the shutter 32 directly, but engages a small catch lever 38 that is mounted on the shutter by its short, and substantially vertical arm 39. The long, or substantially horizontal arm 40 of the catch lever has its extremity bent at right angles to the body, toward the inner wall of the case. On the inner wall of the case is an 'arcuate projection 41 concentric with the cylinder lock 42 which is of the key control. )Vhen the shutter 32 is moved in the direction of the arrow'L, propelled by the projection 31 of the cam plate 22, the latter being moved through the interposition of a deposited coin, the reaction of the spring 35 tends to raise the long arm 40 of the catch lever so that when the shutter has been moved to the extent of its travel, the extremity of said arm 40 moves behind the arcuate projection 41 and holdsthe shutter in its displaced position. A stop 43 on the inner wall of the case and below the cylinder lock prevents excessive movement of the shutter in the direction of the arrow L. Depending from the cylinder of the lock 42 is a projection 44 in such position that when the cylinder of the lock is turned to retract the bolt, this depending projection 44 engages the long arm 40, releasing it from the arcuate projection 41 and permitting the shutter to return to its normal position, its secondary coin slot 34 registering with the coin slot The cylinder lock 42 works upon the bolt 7 through the bell crank lever 45 attached to the cylinder of the lock.

The arm 46 of the bell crank is so disposed as to engage theprojection 4-7 on the bolt 7 when the cylinder is turned in the direction of the arrow M.

Mounted on the cross girt 48, below the coin carrier are two

counting devices

49 and 50, of known construction, their faces registering with the two sight openings 51 These counting devices are directly secured to a plate 53 which is secured to the said girt but slightly separated from it by suitable spacing devices. Within the space so created works a link 54 which engages the lever 55 of the counting device 49, and a forked arm lever 56 which engages the lever 57 of the other counting device 50. The link 54 has an opening through which the lever 55 of the counting device 49 extends, and its upper end is formed as a hook :58 to engage an inwardly projected lug 59 of the cam plate 22, (Fig. 10 and Fig. The lever 56, fulcrumed on the girt 4-8 at 60, (Fig. 3) is connected by a link 61 with the horizontal arm 62 of the bell crank lever 45 on the cylinder look, so that, when the coin control is used, its operation is registered on one counter and when the key control is used registration is made by a supplemental counter, thus checking against each other, the op erations of the key control and of the coin control. Between the faces of the counters and the case is a manually operated shutter 97 to close the sight openings 51 and 52, and accessible only to whoever opens the coin receptacle, (Fig. 10).

The two

side plates

25 and 26 of the coin carrier are so spaced that coin 87 will slide freely between them. Such a coin, inserted through the coin slot 3 of the case, passes the auxiliary coin slot 34 of the shutter and is guided upon and held to the upper end 96xof the coin lever 76. The said upper end 96 of this lever is turned at substantially right angles with its body toward the coin slots, and its upper corner is bevelled or otherwise formed to receive the coin with -certainty. The coin travels along the top edge of the lever 7 6 and of the lever G l and also the edge 63 of the side plate 25, over the

edges

65 and 66 of the cam plate 22 to its seat. Here it rests upon the levers 6 1- and 7 6'and on the edge 75 of a projection 67 of the side plate 26 (Fig. 9). It also has a shoulder 91 which arrests the coin in its travel through the carrier. \Vhen in its seat, the coin is beneath a shoulder 89 of the side plate-2'" and under an inclined face 95 of the side plate 26, which incline normally prevents ejectment of the coin. Directly across the carrier from the projection 67 the side plate 25 is formed with a groove or coin clearance 68. If this groove is filled, the coin cannot escape from between the side plates. If the'groove is clear, under pressure from below, the coin will be pushed upward, sliding over into the groove 68 through thewedging reaction of the inclined face 95, thus permitting it to escape by the inclined face 95. Obstruction to the coin entering the groove is provided in the lever 69 mounted on the outside of the side plate 25 and having an arm 70 extending through an arcuate slot 71 in the side plate 25 to fill the groove 68 (Fig. 3 and Fig. 8). To clear the groove the arm 7 0 moves into a depression 72 ofthesanie depth as the slot 68.

When the coin carrier is in normal position the arm 73 of the lever 69 encounters the hub of the shutter 32, holding the arm 70 in the groove 68. lVhen the coin carrier with coin is turned in the direction of the arrow X, the arm 73 encounters the stop 74 which encounter effects the withdrawal of the arm 70 from the groove 68. The cam plate reacting to its return spring, bears by its tie portion 83 against the coin control lever 76 pressing it against the coin which, when re leased by the arm 70 moving out of the groove 68, is discharged from the coin carrier. The coin control lever '76 bears against the coin by the projection 77. Should a washer be substituted, this projection would penetrate the washer, the extent of penetration being suliicient to throw the mechanism out of time so the bolt is not worked, yet to discharge the washer so -it cannot remain and interfere with the subsequent use of a good coin. The function of the auxiliary lever 6-1 is to shroud or guard the projection 77 so the coin can ride over it without catching on it. The extremity of this auxiliary lever rests on the spacing post 28, its bottom at 94' is cut away so that it cannot press upon the tie portion 83 of the cam plate 22 or encounter the shaft 19. The coin control lever has a downward projection 84 which does encounter said tie portion 83 of the cam plate 22, and causes the latter to turn under reaction of a coin. The under side of the coin control lever 76 is cut away to clear the shaft 1.9 which likewise is formed with clearance for the

levers

64 and 76.

On the side plate 26, and adjacent the spacing post 27 is a lever 78 fulcrumed at 79 (Fig. 3 and Fig. 6). It is this lever which is formed with the projection 23 that is controlled by the cam plate The projection 23 normally bears upon the cam plate at 80', and it also is forked or slotted to straddle the edge of the side plate 26. \Vhen the cam plate 22 is turned with the coin carrier, through interposition of a coin, the projection 23 of the lever 78 remains at in which the position it encounters the bolt 7. If however there is no coin in the coin carrier, the projection 28 rides down the edge 81 of the cam plate, which remains stationary. The projection 23 is thus de pressed below the plane of engagement with the bolt 7. One spring 82 mounted. on the spacing post 27 between the lever 64 and the lever 78 serves to maintain the coin control lever 76 with the auxiliary lever Gel, and the lever 78 in appropriate position. The lever '78 extends a canopy over the levers 64K and 76, which guides and holds the de posited coin to its course of travel.

In the case of inserting a wrong coin, which in the nature of things would be of smaller diameter, such wrong coin passes through the coin carrier freely. It passes by the link (3] connecting the forked arm lever 56, which link acts as a back to the pocket. The pocket 95) is formed with an upturned lip 100 which projects from its bottom beyond the front of the case so that the returned coin canbe readily removed, (Fig. 8).

The operation of my apparatus is as follows zlhe patron inserts a coin or token at the coin slot 3 (Fig. 1) and it passes thru the slot 34 of the shutter 32. (Fig. l.) The canopy of the lever 78 directs the coin to the coin control lever 76 and to the ways on the

side plates

25 and 26 of the coin carrier, along which it travels to the coin seat. (Fig. 3 and Fig. 6.) On reaching its station in the coin seat it is located therein by the shoulder 91 (Fig. 3 and Fig. 8), to which shoulder it is held by the arm 70 of the lever 69. The coin is further held in its seat by the shoulder 89 (Fig. 9) which is parallel with the face of the coin and the face which is inclined to the face of the coin. hen the patron turns the operating handle 21 clockwise, as viewed in F 1, the coin is brought to bear upon the projection 77 of the coin control lever 7 6 (Figs. 5-7 and 9). The coin control lever 7 6, by its projection 84, presses against the tie portion 83 of 0am plate 22 causing the cam plate to turn with the coin carrier to which the operating handle is attached by the shaft 19 (Fig. 0 and Fig. 9.) Inasmuch as the cam plate 22 turns with the coin carrier as tho a port thereof, it maintains the lever 78 (mounted on the coin carrier) in fixed position relative to the coin carrier because the projection 23 of the lever 78 rests upon the cam plate. The projection 23 is thus constrained to move in a circular path. In this path liesthe vertical flange 24 of the bolt 7 when the latter is in its shot position. (Fig. 2.) Continued turning of operating handle 21. causes the projection 23 to encounter the flange 24 and retract the bolt. Substantially coincident with the retraction of the bolt 7 is the encounter by the projection 73 of the lever 69 by the projection 74 of the case (Fig. 3), which causes a clockwise movements of the lever 69, as viewed in Fig. 3 and Fig. at removing the-extremity 70 of the lever 69 from the coin channel (see also Fig. This extremity is in fact the key which looks the summarized combination in operative relation thru the coin. The projection 77 of the coin control lever 7 6 bears against the coin impelled by the return spring of the cam plate 22. (Fig. 3.) The coin, pressed thus against the inclined face 95, is forced against the extremity 70 of the lever 69. \Vhen the extremity 70 is removed as described, the coin is forced to the left as viewed in Fig. 9, the right hand edge rising under the pressure of the coin control lever 76 and following the incline 95 until the coin is forced free and thus ejected from the coin carrier. Each time a coin passes thru the coin carrier as described the counter. 4:9 is caused to register thru the link 54 which connects the counter arm 55 with the cam plate 22. (Fig. 3 and Fig. 10.)

In turning with the coin carrier sufficiently to withdraw the bolt 7, the cam plate 22 also causes the shutter :32 to close the coin slot 3 thru the instrumentality of the projection 31. of the cam plate, which projection encounters and moves the shutter. (Fig. 4 and Fig. 7.) \Vhen the shutter 32 has been moved sufficiently to close the coin slot 3, the spring controlled catch lever 38 engages, by its arm 40 the projection 41 4). It is thus impossible for another patron to insert a coin and have access to the compartment until the shutter shall have been released.

The patron leaves the compartment by turning the exit handle 13 (Fig. 2) which withdraws the bolt 7 thru encounter by the lobe 16 of the cam 15 (attached to the exit handle) with the shoulder 17 of the bolt. This operation, while it permits egress, leaves the coin slot 3 still closed and service inaccessible to another patron.

The attendant whose duty it is to maintain the service by keeping the compartment clean and its supplies renewed, gains access by means of his porters key inserted in the key hole 4 and turned to rotate the cylinder lock l2 in the direction of the arrow M (Fig. 3). Such movement of the lock cylinder swings the arm 46 of the attached lever 45 into engagement with the projection 47 of the bolt 7 and withdraws the latter. (Fig. 2.) Another projection 44 on lock encounters the arm 40 of the catch lever, disengaging it from the projection 41 and permitting the shutter to reopen the coin slot 3. The other arm 62 of the lever 45 is connected by the link 61 and the lever 56 with a second counter 50 so that each time the key control is operated, such op eration is recorded by the second counter 50.

The rendering of service by my apparatus calls for a definite cycle of events 1. The unlocking of the apparatus thru deposit of a coin and accompanying registration of the coin deposit; and occupation of the compartment:

2. Exit of the patron; by use of the exit handle:

Opening of the compartment by use of the key control thru instrumentality of the porters key; registration of such opening; and refurbishing of the compartment.

There is therefore a double check on the use of the compartment and reliability of the attendant. Theoretically both counters should register the same-there should be recorded as many nonpaid admittances as paid admittances. Should the registered operations of key control exceed the registered operations of the coin control the presumption would be that some one is improperly admitting patrons by use of the key control either as a matter of accommodation of or profit, and in either case defrauding the proprietor. There is no good excuse for failure to care for the compartment because in any case, the attendant must go to the door and use his key to release the shutter in order to make service available for a new patron. 'ihe proprietor is thus reasonably assi'ired that he not being defrauded thru misuse of the porters key and that his patrons are not being defrauded thru default in rendering the service for which they pay.
