SPECIFIQATION forming part of Letters Patent No. 691 ,746, dated January 28, 1902.

Application filed September 25, 1900. Serial No. 31,034. (No model.)

To aZZ whom it may concern.-

Beit known that LJosErn H. CHAMP, acitizen of the United States, and 'a resident of Cleveland, county of Cuyahoga, and State of Ohio, have invented a new and useful Improvement inCoin-Controlled Apparatus, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

The object of my invention is to provide an improved coin-controlled apparatus. It is especially adapted for use in the refilling of bicycle-tires with fluid undep pressure.

It consists of the means hereinafter described, and particularly pointed .out in the claims. t The annexed drawings and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting but one of various mechanical forms in which the principle of the invention may be used.

Figure I is a vertical transverse section through the casing ofthe machine, but showing in side elevation all parts of the machine inclosed by such casing excepting the ex-- pansion-cyclinder, which would be nearer to the observer. Fig. II is a rear elevation of the mechanism inclosed by the casing and showing the latter in vertical section at right angles to the section of the preceding figure. Fig. III is a detail top plan of the handle mechanism connected with the fluid supply and exhaust valve mechanisms and with the upper portion of the coin-controlling mechanism, such figure also showing the magnet that operates below the coin-chute. Fig. IV is a ftbnt elevation of said members of the immediately-preceding figure, but having that portion of the front casing which carries the handle removed. Fig. V is a detail,

. partly in vertical'section and partly in vertical side elevation, of one of the twin valve mechanisms shown in the immediately-preceding figure. Fig. VI isadetail inside elevation ofthe lower portion of the coin-controlling mechanism. Fig. VII is a top plan viewroftthe members of the immediately-preceding view. Fig. VIII is a detail of the backpressure-val ve ll'l ecl1anism,sl1owin g the valvechamber in section and the valve in side ele= vation. Fig. IX is a detail, partly in side elevation and partly in vertical section, of the members of the immediately-preceding figure in a plane at right angles to such lat:

' public from access to the inclosed mechanism and also protect the latter from the weather. It is preferably provided at its rear with a door a, whereby privileged access may be had to its interior. Two upright cylinders B B are providedthe one, B, being a storage-cylinder of compressed carbonic-acid gas and the other, B, being an expansion-cylinder to permit the cool and condensed gas to warm and rarefy before beingsubject to draft for tires, respectively communicating by tubes 1) b with the pressure-regulator 0, having a gagedial 0, under conditions adapted to automatically cause gas from the storage-cylinder to pass under a predeterminedpressure into the expansion-cylinder. A tube d, provided with a strainer 01*, carries the fluid from the expansion-cylinder B to the bottom of the valve-cylinder e,whe1'ein communication with tu-be f, connected with the central portion of said cylinder, is controlled by a valve having a tendency to be -maintained in raised position by a spring, such raised position of the valve shutting ofi communication within the valve-chamber between said tubes cl and This fluid-supply-valve mechanism is a duplicate of the exhaust-valve mechanism here inafter referred to, and the interiorconstruction of each is shown by the single view of Fig. V. Said tube f depends in the lower loop 2' below the horizontal line of the tire-feed n0zzle j, which latter passes through thelower portion of the front wall of the casing A. The

rear upper portion of such lower loopii consage of the fluid in outflow, is valve m, loosely fitted and allowing sufficient space between itself and the inner wall of its chamber to permit passage of the fluid between the two. This valve is circular in horizontal section, which section is of such less diameter than the similar section of said chamber Z as to permit a limited quantity of fluid to pass freely between the vertical circular walls of said valve and chamber as the fluid passes from the lower to the upper portion of said valve-chamber.

valve rises, so as to insure the valve properly fitting against the valve-seat, so as to seal-the latter. of said back-pressure-valve chamber connects with tube 19, the upper end of suchtube con necting with the lower portion of valve-cylinder q, such cylinder q being of construction and having an inclosed upwardly springpressed valve, such as shown in Fig V, the

side port 0' of such cylinder qbeing open to the interior of the casing and acting as an e haust.

Each of the twin valve-cylinders e and (1 has a pivotal angular lever whoseilowerportion engages with the top of a valve-stern,

each such pivotal lever being adapted to be depressed by a cam carried on the lower slide of horizontal slide G, such lever, stem and: cam of thesupply mechanism being respec tively lettered as s t 4:, while the corresponding members of the exhaust mechanism are respectively lettered as s t c, said slide being thrown in either direction by arm D, fastened on rock-shaft E and working loosely between two lugs a, depending from the slide between said two cams i) o. The shaft projects through the upper front wallof the casing and is provided with exterior handleiF. An arm G is fastened to said shaft Eata point thereof between said slide-barO and the front casing-wall, such arm being pivoted to the upper end of rod H, which latter has its lower end connected to angle-iron 19 which latter is also connected to depending ratchetbar J. This latter bar has vertical sliding movement in guideways c projecting horizontally from vertical web K of bracket L, fastened to the lower portion of the frontwall of the casin g. An arm M projects rearwardly from said web K and has pivoted to its outer extremity the bell-crank N, the free end of thehorizontal arm of such bell-crank carrying the coin plate O, the free end of the vertical depending arm of the bell-crank carry- The side port at inthe lower portion ing the hook (1, upon which detachably rests the horizontal lug e, projectinglaterally from the free end of the long arm of trip P. Pawl R is pivoted to said web K so as to swing in a vertical plane in and out of engagement with said ratchet-bar K, its horizontal arm being provided with a depending cam f, adapted to be engaged by upwardly-projecting lug g on the free end of the short arm of said trip P. A dog Q is also pivoted to said web K and has its front arm h adapted to be engaged by horizontal lug i, carried on ratchet-bar J, the reararm j of the dog being adapted to bear down upon lug Z, projecting laterally from the short arm of said trip as the ratchet-bar completes its upward movement.

A coin-slot s is formed in the front wall of the casing and connects with a coin-chute S, the latter adapted to conduct the coin so as to dischargeitself on coin-plate O. The magnet T is suitably mounted by sleeve E on rock-shaft E and is adapted to have rocking movement as actuated by said rock-shaft transversely beneath the opening w, formed in the floor of the coin-chute, the construction and adaptation of said members being such as to permit the desired coin to pass freely down through the chute without hindrance from the magnet, but to arrestslugs and pieces of matter which might be Wrongfully introduced into the coin-slot and to cause all undesirable material possible to be attracted by the magnet to be lodged on the latter,and thus to prevent such undesirable material from passing down through the coinch ute to the point where the desired coin should fulfil its function in the operation of the machine. \Vhen the rock-shaft is turned by the handle F, all such base material which has been attracted to the working face of the magnet will be'thrown from'off the latter and fall do'wn withinthe casing.

The operation of the machine is as follows: The bicyclist removes the cap from the nipple of his tire and places his wheel on the tire feed nozzle j, with the opened nipplefitting in the open end of such nozzle, the month of the latter being of size and shape adapted to effect, substantially, an air-tight joint with such open nipple of a wheel-tire. clist then slips a suitable coin into the slot, whence the coin passes through the coinchute and is discharged onto the coin-plate. The latter thereupon swings downwardly and tilts the vertical armof the bell-crank N toward ratchet-bar J, so as to cause hook d to pass from under lug e'of trip P. The long arm of the trip thereupon falls of its own weight and causes lug g onits short arm to engagewith cam f of pawl R, thereby causing suchpawl to disengage itself from the ratchet bar. The bicyclist then turns the handle F to the right and there maintains it. As the handle F is thus turned toward the right its arms D throws slide 0 toward the right, thereby causing the cam o to be disengaged from lover s, so as to permit the up- The bicyward springpressed valve in cylinder to rise and close communication between tube 19 and waste-port r, and simultaneously therewith cam 12 depresses lever s, which latter depresses the upwardly-spring-pressed valve in cylinder 6, thereby establishing communication between tubes (1 and f. At the same time with'such movement of slide 0 toward the right arm G of rock-shaft E raises rod H, which latter raises ratchet-bar J, so that lug t of the latter engages with arm h of dog Q, thereby causing the remaining arm j of said dog to bear down upon lug Z of the short arm of trip P, so as to raise the long arm of the latter and permit hook d to automatically swing beneath lug 6, so that when ratchet bar J again descends and releases dog Q from pressure upon the short arm of trip P the long arm of the latter will in turn descend, and its lug e will again seat itself on hook 01. Communication of gas from expansion-cylinder B being bad with tube f by reason of said movement of slide 0 toward the right, such gas under pressure passes through lower loop 41 upwardly into valve-chamber l and thence upwardly through upper loop 0 and then downwardly into and out through the tirefeed nozzle into the nipple of the tire. The backpressure of the fluid-is; so long as the wheel is in place on said nozzle, sufficient toprevent the valve m from rising upwardly, so as to seat itself against outward passage of the fluid. The said back pressure is due to the presence of the wheel-tire on nozzle j, which pressure is sufficient to so afiect the conditions of the gas in the upper portion of Valve-chamber I as to result in sufficient back pressure against the top of valve m to cause the latter to remain in its down position, it being understood that when gas first enters said valve-chamber its pressure'in the latter is slight and insufficient, to raise valve m, so that it passes upwardly around the latter and thence to the tire. When the bicyclist is sat-isfied as to refilling of his tire; he lets go of the handle F and lifts off the wheel from nozzle j, whereupon and whereby the previous condition will be so changed as to relieve valve m from the said back pressure of the fluid. Such valve will thereupon be immediately forced upwardly againstits seat m by the fluid under pressure from below and further discharge of fluid from out nozzle j will be stopped. The

removal of the tire from nozzle j causes the gas in the upper portion of valve-chamber Z I to be suddenly relieved of its said back pressure, so that valve m is thereby subjected to great pressure of the fluid against'its bottom, while its top is relieved from fluid-pressure to such extent as to cause it to be at once forced upwardly against its valve-seat mby reason of the then excess of gas pressure against its bottom relatively tothe gas-pres sure agaiustits top. As soon as the bicyclist lets go of the handle F the weight of rod H and its ratchet-bar will be sufficient toovercome the inertia of slide 0 and'rock-shaft E will be automatically turned to the left, thereby releasing lever s from cam u, so that the upwardly-springpressed valve in cylinder e will cut offcommunication between tubes at and f and cam Q) will depress lever s, which latter will depress valve-stem 25, thereby causing the upwardly-spring-pressed valve in cylinder q to be de'pressed,so as to open communication between tube 19 and waste-port r. This latter communication will then permit the fluid under pressure beneath valve on to pass out through portn into tube and thence through cylinder q out through waste-port r. Valve 102 thus being relieved from fluid pressure below, automatically drops of its own such trip to release bearin g upwardly against cam f of pawl R. Such pawl will thereby have automatically rejoined engagement with the ratchet-bar, so as to positively lock'the latter against upward movement until the drop of a coin shall again operate the coin-.

controlling mechanism. The different mem 1 bers of the machine are thereby restored to their respective positions, such as they were" assumed to be in at the beginning of the described operation.

ICO

The back-pressure valve m and its coworking members fulfil the office of automatically and absolutely rendering it impossible for a plurality of tires to be charged with fluid by the introduction into the machine of but a single coin. The construction is thereby such that the machine must receive a coin for every tire that is supplied with fluid fromit, and communication between the expansioncylinder and the back-pressure-valve chamber is cut off before such back-pressure-valve chamber'is placed into communication with the exhaust, and when this latter communication takes place the back-pressure valve and its chamber become idle until the operation of the bicyclist hereinbefore described is repeated. The construction and relative proportions of the intermediate members between the exterior operating-handle of the machine and thefiuid supply and exhaust valve mechanisms are such as to work .to-

gether toward the accomplishment of'the' above-described resultthat a coin must be slipped in the slot for each tire supplied with fluid from the machine. To such end the arm of the handle-shaft and its two engaging lugs on the slide whose cams depress the spring-pressed valves respectively of the fluid supply and exhaust mechanisms are so I relatively proportioned that there is a decided 1 when and as desired in the normal operation of the machine.
