Original application April 18, 1935, Serial No. 17,096. Divided and this application October 31, 1935, Serial No. 47,676

7 Claims.

My invention relates broadly to sanitary basins and more particularly to a coin actuated mechanism for controlling the supply of sanitary inserts to basins.

This application is a division of my application Serial No. 17,096, led April 18, 1935, for Automatic sanitary insert basin, which has matured into Patent 2,043,264.

One of the objects of my invention is to provide a construction of coin control mechanism for governing the successive feeding of sanitary liners or inserts to basins.

Another object of my invention is to provide means for effectively blocking the feed operation of sanitary liners to basins until a coin of proper denomination is deposited in a coin actuating mechanism.

Still another object of my invention is to provide a construction of coin operating mechanism for controlling the feeding of sanitary liners to basins in which a coin of proper denomination must be deposited in the coin operating mechanism as a precedent to the operation of the sanitary liner feeding mechanism.

A further object of my invention is to provide a construction of coin control mechanism for governing the successive feeding of sanitary liners to basins in which a deposited coin serves as a thrust transmission member in cooperation with the movement of a displaceable actuating member.

A still further object of my invention is to provide a linkage system operatively connected with a thrust bar adapted to be shifted to either of two limiting positions under control of a displaceable actuating member when a coin is inserted in a position engaging the displaceable actuating member.

Other and further objects of my invention reside in the construction and arrangement of parts in a coin control mechanism for feeding sanitary liners to basins as set forth in the following specication and referred to in the accompanying drawings in which:

Figure l is a front elevation of the housing enclosing the coin control mechanism of my invention as applied to the mechanism for supplying sanitary liners to basins; Fig. 2 is a side elevation partially in section showing more particularly the coin control mechanism for controlling the supply of sanitary liners to the basin; Fig. 3 is a transverse, vertical section taken `on line 3-3 of Fig. 2; Fig. 4 is a similar view to Fig. 2, but showing parts as they appear when a coin has been deposited and the thrust bar actuated; Fig. 5 is a transverse, vertical section taken on line 5-5 of Fig. 4; Fig. 6 is a horizontal section taken on line '.--E of Fig. 2; Fig. 7 is a central vertical transverse, sectional view on an enlarged scale taken on line T-'I of Fig. l and showing the sanitary liner supply magazine and the association of the coin control mechanism therewith in a position prior toactuation; and Fig. 8 shows the sanitary liner in position in the basin after an operation of the coin control mechanism of my invention.

My invention is directed to a coin control mechanism for operating a sanitary liner feed mechanism for basins.

Where it is desired to employ the sanitary liners for wash basins in public places, such as hotels, comfort stations, railroad trains, etc., I arrange a coin control mechanism whereby, upon the insertion of a coin and the actuation of a lever, a liner may be moved into position within the basin.

Referring more particularly to the accompanying drawings, I have illustrated a wash basin having a rear wall I and a front wall 2 angularly inclined toward each other at substantially acute angles. A drain opening fil is provided intermediate the lower edges of the rear wall I and front wall 2 of the basin. The walls I and 2 forming the basin are connected at their opposite ends by closures 48 and 49. The basin is supported beneath the top section 50 which is provided with an upwardly extending rear section 5| adapted to be secured to a suitable supporting surface 52. The plumbing fixtures constituted by valves 53 and faucet member 58 are mounted with respect to the top section 5U in conventional manner. Hot and cold water connections are made through the valves 53 with the faucet 58 through conventional plumbing taps. The basin formed as illustrated is shaped to receive a sanitary liner 3. The sanitary liners 3 are stored in manifolded relation as indicated at I3 in a magazine carrier 54 located directly beneath the front of the top section 50 of the xture constituting the basin as illustrated. The magazine carrier 54 supports the liners in manifolded relation as indicated at I3 in a position in which the liners 3 may be successively fed to the basin by a vertically upward movement. The liners 3 are fed to the basin in a vertical direction intermediate the end plate 55 and the edge 56 of the top section 5U and through the slot 51 formed in the upper portion of the magazine carrier 54. The sanitary liners 3'are continuously urged in the direction of plate 55 by means of springs 21 acting between the inside face of the magazine carrier 54 and the follower plate 59. The feed mechanism for the sanitary liners 3 includes the liner pickup ngers I4 carried by a laterally extending bar member I 'I. The pickup bar member I1 is mounted to move with a slight amount of lost motion in the ends of the pickup bar arms i6 so that the liner pickup iingers may follow each sanitary liner successively for insuring the delivery of each sanitary liner in a vertical path. 'Ihe pickup bar arms I6 are denomination in the coin chute 35.

carried by a pivoted bar I 9 which is journaled in bracket members 69 mounted on the rear surface of the magazine carrier 54. An operating lever 20 is connected with the pivoted bar I9 and to the pickup arms I6 and has an end grip 6I thereon which may project beyond the front of the top section 5I) in a convenient position and manually gripped for angularly shifting the liner pickup ngers I4 and effecting the ejection of each successive sanitary liner 3. The pickup bar I1 is adapted to slide vertically within limits dened by the pickup bar guide slot 26 formed in the vertically extended portions of the end closures of the basin indicated at 49 in the cross-sectional view7 Fig. '7. I provide a box-like enclosure I2 for housing the end of the pickup bar I1, pickup bar arms I6, and the end of the pivoted bar I9 for the pickup bar I1. A similar box-like enclosure I2 is provided over the opposite end of the pickup bar I1 and pivoted bar I9 and pickup arm I6 as illustrated in Fig. 1.

The lever 20 is normally maintained in an extreme upper position illustrated in Figs. 5 and '7 by means of a suitable coil spring 1.9 connected between a point 11 on lever I6 and housing 63. With each successive actuation of lever 20, the coil spring 16 returns lever 29 to its extreme up permost position yready for its successive operation.

In order to replenish the supply of sanitary liners in the magazine carrier, I provide a refill door I'5 hingedly mounted at 3I to allow 'sanitary liners in manifold relation to be inserted into the compartment as the liners are used rfrom time to time. A suitable lock 62 is provided lfor preventing unauthorized access to the magazine carrier. In order to open the rell door I5, the lock 62 is unlocked, the Vsanitary liners in manifold relation inserted in the compartment and the .successive feeding of the .sanitary `liners thus continued.

The coin mechanism is enclosed within the housing 63 in the front of which there is arranged a coin slot 21 for Vintroducing coins of suitable The coin chute v serves to guide Vcoins shown generally at 36 vsuccessively into the position by which the coin Vis employed .as a thrust member in coaction with a coin thrust bar 31 under control of a coin thrust bar spring 38. The coin thrust bar 31 is mountedfor reciprocal movement in a coin thrust bar guide 49 secured by a suitable bracket mounting 39 to the interior wall'of the housing 63. The coin thrust bar guide `III) has a projection 40a thereon adapted to arrest the gravitation of a coin, such as 36, in its downward path of movement in coaction with lthe receiving 'thrust bar 4I. The receiving thrust bar 4I has its end face shaped to conform with the contour of a coin for imparting angular movement to the lever 45, as

illustrated in Figs. 2 and 3. The lever 45 is pivoted with respect to housing 63 at the fulcrum 65 land forms a vconnecting linkage between the receiving thrust bar -III andthe `lever locking bar 33. The lever locking bar 33 is shiftable horizon-y tally within the lever locking bar guides 34 in a path which normally obstructs the movement of operating lever 29.

Operating lever 29 projects through slot 66 in housing 63 and through 'a 'keeper 32 which prevents tampering with lever locking bar 33. Keeper 32 is vertically shiftable in slot 66. The lever locking vbar 33 is normally maintained in a position which obstructs the movement of operating lever 2U by means-of a spring 46 which tends to maintain lever in the position illustrated in Fig. 2. Lever locking bar pawl 43 is pivoted at 68 on lever 45 and is normally tensioned by means of spring 69 secured at 10 to the lever locking bar pawl 43 and at 1I to the housing 63. The lever locking bar pawl 43 operates to engage in notch 12 in level` locking bar 33 in the position shown in Fig. 4 for removing any obstruction to the operation of lever 29. The receiving thrust bar guides 42 control the path of movement of the receiving thrust bar 4I. It will be observed that there is a lost motion connection 45a between lever 45 and receiving thrust bar 4I, and a lost motion connection 45h between lever 45-and lever locking bar 33.

The kcoin thrust bar 31 has an operating member 28 terminating in a release knob projecting through a slot 13 in housing 63 which allows manual control of coin thrust bar 31 independently of the thrust member 14. Thrust member 14 is normally maintained in an extreme projected position by means of spring 38, as illustrated in Figs. 2 and 6, subject to inward thrust by which vcoin thrust bar 31 imparts horizontal movement to receiving thrust bar 4I if a coin 36 is located in the path of the lcoin thrust bar 31 and receiving thrust bar 4I. As sho-wn in Fig. 2, the coin 36 when deposited in coin slot 21 will be normally arrested in its downward movement and lodged between projection 49a and receiving thrust bar 4I, whereby pressure imparted to thrust member 14 is transferred through receiving thrust bar 4I for angularly rocking lever 45. In the event that no coin is inserted in the slot 21, repeated thrusts on member 14 will have no iniiuence at all on receiving thrust bar 4I or lever 45, as under this condition, there is no medium by which to transfer the applied thrust.

I provide a coin receiving receptacle 15 within the housing 63 to which access maybe had from time to time kthrough the locked door 29 in the housing 63.

The basin is constructed with a perforate side wall I and perforate end walls 48 and 49. Side wall I is provided with a laterally extending slot 23 through which used liners may be ejected by operation of the liner ejector bar 4. The ejector bar 4 is carried by ejector bar arms 5 which conneet with the laterally extending pivoted bar 6 which is journaled at opposite ends in brackets 18 and 19 carried by projecting portions of end plates 48 and 49 of the basin. The laterally extending pivoted bar 6 has an arm 89 connected intermediate the length thereof which arm connects to one end of spring V8I, the other end of which is secured in position 82 to a central portion of the-drain housing indicated generally at I Il. The ejector bar arms 5 are wholly enclosed at opposite ends of the basin by housings 83 as shown more particularly in Fig. 1. An ejector bar 4 is connected with the extremities of the arms 5. An ejector bar treadle connecting rod 8 connects with the end of ejector bar operating crank 1 and provides a connection to a foot treadle 84. The foot treadle 84 is pivoted in bracket member 85 mounted on vthe floor or other support indicated at 99. By depressing the foot treadle 84, connecting rod 8 is drawn downwardly which operates ejector bar crank 1 turning ejector bar shaft 6 and angularly moving ejector arms 5 to shift the liner ejector bar 4 in an annular path. Ejector bar 4 is free to move in an annular path by reason of the ejector bar guide slots 24 which are formed in the end closure plates 48 and 49.

In order to avoid overflowing of the basin, the

v rear wall I and the front wall 2 of the basin are each provided with laterally extending apertures represented at la and 2a, respectively through which iluid may pass into the drain housing I to prevent seepage into the magazine carrier or overflowing.

The upper edge of the side wall 2 and the laterally extending plate 55 which connects therewith are provided with vertically extending slots which allow the liner pickup fingers I4 to shift vertically for the purpose of feeding a sanitary liner to the basin.

The locking mechanism is provided to prevent tampering with the sanitary insert feed mechanism unless the proper coin is deposited. Inasmuch as the basin has perforated walls, the basin in itself will not hold iluid. Inasmuch as the ejecting mechanism is operative independent of the coin control mechanism, a sanitary liner after having been used in the basin may be readily disposed of, leaving the basin with its perforate walls incapable of holding uid. It, therefore, becomes essential to condition the coin control mechanism by the insertion of a coin for permitting a fresh sanitary insert to be supplied to the basin. The lever locking bar 33 cannot be removed from its position obstructing the path of the lever 28 until a coin is positioned between the coin thrust bar 3l and the receiving thrust bar 4|. The sanitary insert which is supplied und-er control of the coin actuating mechanism may be applied to basins of various descriptions for medicinal, dental, chemical, and other purposes.
