TIRE-INFLATER.

SPECIFICATION forming part of Letters Patent No. 691,745, dated January 28, 1902.

` Application inea July 1e, 1900.-

T0 @ZZ whom it may concern:

Be it known that I, JOSEPH H. CHAMP, a citizen of the United States, and a resident of Cleveland, county of Cuyahoga, and State of Ohio, have invented a new and useful Improvement in Tire-Inliaters, ofwhich the following is a specification, the principle of the invention bein g herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish itfrom The object of the invention is to provide an improved tire-iniiater, especial attention having been given to same in its fitness for use as connectedwith coin-controlled apparatus.

The nature of the invention consists ofthe means hereinafter described, and particularly pointed out in the claims.

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.

FigureI, is a vertical transverse section through the casing of the machine, but without section through the inclosed mechanism.

inclosed by the casingand showing the latter in vertical section at right angles to the section of the preceding figure. Fig. III is a View, taken like the immediately-preceding one, of a modiied form of the casing-inclosed mechanism. Fig. IV is a detail top plan of the handle mechanism connected with the duplicate valve mechanisms and of the coincontrolling mechanism. Fig. ,V is a front ele- Vation of .said members of the immediatelypreceding ligure, but having that portion of the front casing which carries the handle removed. Fig. VI 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 gure. Fig. VII is a detail of a portion of the coin-controlling mechanism. Fig. ...VIII is a detail at right angles to the plane in which the immediately-preceding4 gurey is taken. Fig. IX is a detail view, mainly in' vertical section, of

struction, its purpose being to exclude the with a door a, whereby privileged access may. l

be had to its interior. Two upright cylinders B B are provided, the larger one, B, being a storage-cylinder of compressed carbonic-acid gas andthe smaller one, B, being a measure-cylinder to permit a given limited volume of gas to be subject to draft upon insertion of a certain coin into the coin-slot. Cylinder B communicates by tube b witlgthe pressure-regulator c, having a gage-dial c', subject to conditions adapted to automatic-x ally cause gas from such storage-cylinder to pass under a predetermined pressure into the tube d. This tube d carries the iiuid to the bottom of the valve-cylinder e, wherein communication with the tube f, connected with the upper side 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 0E communication Within the valve-chamber be-v tween said tubes d and f. This valve mechanism controls the induction of the iiuid relatively to the measure-cylinder and is a duplicate of the valve mechanism, hereinafter referred to, which controls the eduction of the iiuid relatively to the measure-cylinder, and the interior construction of each such Valve mechanism is shown by the single view of Fig.VI. Said tube f discharges into the lower portion ofthe measure-cylinder B', the upper portion of such measure-.cylinder connecting with one extremity of a tube g, the opposite extremity of said tube g connecting with the bottom of valve-cylinder h, such cylinder h being of construction and having an inclosed upwardly spring-pressed valve such' as shown in Fig. VI, the upper side portion of such cylinder h connecting with tube t,

Awhich latter connects with the vtire-feed noz--v .imi

zle j, projecting vout through the lower por--fV i tion of the front wall of the casing A.

Each of the twin valve-cylinders cand h has IOO of the latter having free sliding movement in bearing-boxes 7a. Said lever, stem, and cam ot the induction mechanism are respectively lettered, as l m 0, While the corresponding members of the eduction mechanism are respectively lettered, as Z m o'.

Rock-shaftD has a sleeve E threaded thereon and ad justably clamped thereto by a setscrew 19, such sleeve having rigidly secured thereto a weighted arm q. The rock-shaft is further provided with a rigid arm r, adapted to work freelym within a slot s, formed longitudinally in a horizontal plate F, located beneath the horizontal slide C. The rock-shaft is adapted to be Operated bya handle G, which is suitably fitted in and projects outwardly from the central portion of the front Wall of the casing.

A coin-slot H is in the front wall of the cas ing and connects with a coin-chute L, terminating above receptacle t. An additional chute N is located below the discharge end of plate F, and a cash-box P is located 'below the discharge end of such chute.

The slide C has its approximately middle portion provided with a transverse receptacle i, of size adapted to receive a desired coin in a vertical plane above said plate F. Said coin-receptacle t has its lower central portion formed with an opening -v of size suitable to permit arm r to work freely therein when there is no coin in receptacle t.

The construction of the foregoing members is such that when a coin has entered vreceptacle t it drops onto plate' F and there remains as a barrier against the passage of arm fr through opening o, so that when handle Gr is turned to the right arm r engages against the face of the coin, and the latter then serves as a mechanical member to cause slide C to be correspondingly moved to the right until the coin has reached a vertical plane to the rightrof plate F. The coin then being freed from support falls ofA its own gravity into chute N and is therefrom dropped into cashboX P.

In Fig. III is shown a modification wherein an upright cylinder B2 is introduced in fluid connection between the pressure-regulator c andthe induction-valve cylinder e. The purpose of such cylinder B2 is to permit any cool and condensed carbonio-acid gas to warm and rarefy before being subjected to draft for tires. Such expansion-cylinder has its top provided with fluid connections, such as shown in Fig. IX. Tubesfand g in this instance are shown as each communicating with the top of the measure-cylinder B'.

The operation of the machine is as follows, assuming certain members in position such as is shown in Fig. V: The bicyclist removes the cap from the nipple of his tire and places his wheel on the tire-feed nozzle j, with the opened nipple fitting in the open end of such nozzle,the mouth of the latter being of size and shape adapted to eeet substantially an airtight joint with such open nipple of a wheeltire. The bicyclist then slips a suitable coin into slot H, whence the coin passes down chute L into coin-receptacle t. The bicyclist then turns handle G toward the right, causing arm r to throw slide C toward the right, thereby causing cam o to be disengaged from lever l, so as to permit stem m of the upwardly spring-pressed valve in cylinder e to rise, resulting in said valve rising and closing communication between tubes cl and f, and simultaneously therewith cam o depresses lever Z', which latter depresses stem m of the upwardly spring-pressed valve in cylinder h, resulting in said valve lowering and opening communication between tubes g and t, and inasmuch as the measure-tank B was under the assumed condition existing pre viously to the movement of slide C to the right filled with gas under pressure such gas in said measure-cylinder passes therefrom, through-said'open communication in cylinder h, out to the tire-feed nozzlej. By reason of the measure-cylinder B having been cut off by said movement ot' slide C toward therght from communication with tube d it becomes impossible for the bicyclist during the present condition of the mechanism to obtain any more gas than had been previously passed from tube d through the induction-cylinder e. The bicyclist continues hold of the handle Gr, so as to maintain slide C in its said thrown position toward the right until he has satis- Iied himself as to the delivery of gas from the tire-feed nozzle. When he is so satisfied, he may let go of handle G, whereupon the weight of arm q will be sufiioient to overcome the inertia of slide C, and rock-shaft D will thereupon be automatically thrown back to the left into the position shown in Fig. V. Lever Z' will thereupon be released from cam 0', and stem m' of the upwardly spring-pressed valve in cylinder h will rise, so that said valve in its corresponding rising movement may cut 0H communication between tubes g and t', and simultaneously therewith cam o will depress lever-Z, which latter will depress stem fm, thereby causing the upwardly spring-pressed valve in cylinder c to be depressed, so as to open communication between tubes d and f. The eduction means of the measure-cylinder will thereby be cnt off, while the induction means of said cylinder will thereby be established in open communication, so that gas under pressure may `pass freely into the measure-cylinder and be there retained ready for a repetition of the previously-described operation.
