JOSEPH H. CHAMP, OF CLEVELAND, OHIO.

TIRE-INFLATER.

SPECIFICATION forming part of Letters Patent No. 691,747, dated January 28, 1902.

Application tiled December 7, 1900. Serial No. 39,053. (No model.) V

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-Inflaters, of which the fol-- lowing is a speciiication, 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 thel invention is to provide an improved .tire-intlater, especial attention having been given to same in its iitness for use as connected-with coin-controlled apparatus.

The nature of the invention consists of the 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 yprinciple of the invention may be used.

Figure I is a vertical transverse section through the casing of the machine, but without section through the mechanism. Fig. lII is a front elevation'of the mechanism and showing the casing in vertical section at right angles to the section ot' the preceding figure. Fig. III is a detail top plan of the twin valve mechanism and certain connecting mechanism. Fig. IV is a front elevation showing certain members of the immediately preceding figure and having the front casing broken away. Fig. V is a detail, partly in vertical 'section and partly in side elevation, of one of the twin valve mechanisms shown in the immediately preceding gure. Fig. VI is a sectional detail of a portion of the coin-controlling mechanism. Fig. VII'is a sectional detail at right angles to the plane in which the immediately preceding ligure is taken. Fig. VIII shows the check-valve mechanism in different views. Fig. IX is a detail'top plan of iiuid^ connections of the expansioncylindenj Fig. X is a detail, mainly in vertical section, of fluid connections ot' the eX- pansion-cylinder. Fig. XI is a detail view, partlyinvertical section and partly in side elevation, ot' the automatic cut-o between the expansion-cylinder and the tire-feed nozzle. Fig. XII is a detail View, in side elevation, showing the bbearing of the tire-feed nozzle in the casing. Fig. XIII is a detail view in perspective of the tire-feed nozzle and its connections.

The casing A may be of any suitable construction, its purpose beingto exclude the public from access to the inclosed mechanism and also to 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 C are provided, the one, B, being a' storage-cylinder of compressed carbonio-acid gas, the other, C, being an expansion-cylinder. These two cylinders respectively communicate by tubes l) c with the -pressureregulator D, having a gage-dial d subject to conditions adapted to automatically cause gas from the storage-cylinder to pass under a predetermined pressure into the expansion-cylinder.

A tube ecarries the gas from the top of expansion-cylinder C to the lower portion of valve-cylinder E, wherein communication with tubef, connected with the upper portion of said cylinder, iscontrolled by a valve having a tendency to 4be maintained in raised position by a spring, such raised position of the valve shuttingoif communication within the 'valve-chamber between said tubes e and f.

The mechanism -of this valve-cylinder E is a duplicate of the mechanism of valve-cylinder G, hereinafter referred to, and the interior construction of each is shown by the single view of Fig. V. Said tube f is also connected with the upper portion of an initial powerreservoir F at one side thereof, the upper portion'ot the opposite side of such reservoir connecting with one extremity of a tube g,` thev opposite extremity of said tube g connecting with the lower portion of valve-cylinder G, such cylinder G being of construction and having an inclosed upwardly springpressed valve, such as shown in Fig. V, the

upper portion of such cylinder G connecting by tube h with the casing-inclosed end portion of rock-tube H, which latter has its opposite end portion projecting out through the lower portion of the front wall ofcasing A.

Each ofthe twin valve-cylinders E and G has a pivoted angular lever whoselower side engages with the top of a valve-stem, each such pivotal lever being adapted to be depressed by a cam carried on the lower side of horizontal slide J, the opposite end portions of the latter havingr free sliding movement in bearing-boxesj. Said lever, stem, and cam connected withcylinder E are respectively lettered as 7o Z m, while the corresponding members connected with cylinder G are respectively lettered as n o p.

Rock-shaft K has a sleeve L fitted thereon and adj ustably clamped thereto by a set-screw r, such sleeve having a weighted rigid arm M.

Said sleeve is further provided with a rigid arm s, adapted to work freely within a slot t, formed in a horizontal plate N, located beneath the horizontal slide J. The rock-shaft is adapted to be rocked toward the right by a rod P, which depends by pivotal connection from arm M, the lower end of such rod being connected to rigid arm fu, projecting right angularly from the casing-inclosed end portion of rock-tube H, the opposite and outer pro jecting extremity of such rock-tube being provided with a rigid arm tu, projecting right angularly therefrom in direction opposite to the projection of arm o, the outer extremity of such arm w being provided with an upwardlyprojecting tirefeed nozzle The inner extremity of rock-tube I-I is connected in common to the lower extremities of the three several tubes h y e. The upper portion of tube y connects with the upper portion of chamber R, abovediaphragm a', located horizontally across said chamber. The central portion of the lower side of said diaphragm has bearing against stem b', which depends through the lower portion of said chamberR, the inclosed portion of such stem being encircled by a spiral spring o', compressed between said diaphragm and cap d', detachably ttinginthe lower portion of said diaphragmchamber. The lower end of said stem b projects below said cap and has loose bearing upon the free extremity of angular lever e', pivoted to the upper portion of valve-chamber S, said lever resting in loose bearing upon valve-stem j', which projects through the top of said valve-chamber S. Said valve-stem has its lowerextremity connected to valve g', which is upwardly spring-pressed by spring h and controls communication between the upper extremities 0f tubes z and j', communicating with said valve-chamber, respectively, at different horizontal points. The lower and opposite extremity of .said tube j communicates with the top of expansion-cylinder C. Tube h is provided with valve mechanism l', adapted to permit gas to pass downwardly through same, but to prevent upward return passage of such gas.

A coin-slot m is in the upper portion of the front wall of the casing and connects with a coin-chute T. The slide J has its approximately middle portion provided with a transverse receptacle n of size adapted to receive a desired coin above the horizontal plane of` plate N, that portion of slide J adjacent to said coin-receptacle n being'formed in open box form p to permit the free upward projection therein of arm s. Said coin-receptacle n has its lower central portion formed with a slot r' of size suitable to permit arm s to work freely therein when there is no coin in receptacle n; but when a coin has entered receptacle n such coin may drop of its own weight and edgewise onto plate N and there remain as a barrier against the passage of arm s through slot r', such arm then bearing against the face of the coin when force is exerted to rock said arm toward the right and the coin thus serving as a mechanical member to cause slide J to be correspondingly moved to the right until the coin has reached a vertical plane to the right of plate N. The coin then, being freed from the support of said plate, falls of its own gravity into chute V and is therefrom dropped into cash-box W.

Arm s is provided at its upper left portion with a linger s' of size and shape such that the entire linger can never be to the right of the vertical plane passing through coin-receptacle n. This prevents the possibility of a coin being introduced into said receptacle when arm s is to the right of a vertical plane passing through such receptacle under such conditions as to prevent said arm from being readily thrown back to the left when rockshaft K is released by the bicyclist and is subject to the return action of weighted arm M. Padded bumpers X are provided for weightY to strike against at the extremes of its movement.

The operation of the machine is as follows: The bicyclist slips a suitable coin into slot fm', whence the coin passes down along chute T and into coin-receptacle n. He removes the cap from the nipple of his Wheel-tire and places the latter on the tire-feed nozzle az, with the opened nipple fitting in the open end of such nozzle, the mouth of the latter being of size and shape adapted to effect substantially a gas-tight joint with such open nipple of a Wheel-tire. The weight of the Wheel causes rock-tube H to rock to the right, so as to move rod P upwardly, thereby causing arm M to rock the shaft K to the right and cause arm s to bear against the coin in receptacle n', so as to throw slide J toward the right, thereby causing cam m to be disengaged from lever 7c, so as to permit the upward spring-pressed valve in cylinder E to rise and close communication between tubes e and f, and simultaneously therewith cam p depresses lever n, which latter depresses the upwardly spring-pressed valve in cylinder G, thereby establishing communication between tubes g and h. Communication of gas from initial power-reservoir F being had, through tube g and valve-chamber G, with tubeh by reason of said movement of slide J toward the right, such gas under pressure passes into rock-tubel'l. At the same time the gas passes chamber R, thereby depressing diaphragm a and causing stem b to depress lever e', the .latter depressing stem f', which depresses valve g', thereby causing tubes j' .zand valve-chamber S to permiteXpansion-cylinder C to be in open communication with rock-tube H. The tire is thereupon inllated to such full degree of pressure as the bicyclist may desire, whereupon he lifts his wheel from the nozzle The weight Y is then suiiicient to rock they shaft K toward the left, at the same time carrying rod P downwardly and rocking the tube H so as to bring arm w again into horizontal position. Such rocking of shaft K throws slide .I toward the left as arm s bears against the left wall of box-opening p. Cam p is thereby disengaged from lever fn, so as to permit the upwardly-spring-pressed valve in cylinder G torise and close communication between tubes g and h,and simultaneously therewith cam mdepresseslever k, which latter depresses the upwardly-spring-pressed valve of cylinder E, thereby establishing communication between tubes e and f. Gas thereupon passes from expansion -cylinder C into the initial power-reservoir F, lling the latter and also tube g, leading therefrom to cylinder G; but byreason of the communication being closed between tubes g. and h the gas is maintained under pressure in the initial powerreservoir F until a further proper coin is in- Y serted in the coin-slot, whereupon the operation heretofore described is repeated.

The invention accomplishes the valuable result of rendering it necessary that before Y gas can be taken from the tire-feed nozzle to inflate any certain tire a corresponding coin must be introduced in the coin-slot. No tire can be fraudulently filled from the machine. The diaphragm a is sufficiently relieved from gas-pressure upon its surface immediately upon the removal of one tire from the tirefeed nozzle, which removal destroys the pressure existing in the tube y when the tire is on said nozzle, .so that the valve g thereupon instantaneously closes communication between tubes a' and j', thus rendering it impossible for gas to again pass from expansioncylinder C through the latter tubes into rocktube H until a further coin has been deposited in the coin-slot and the previously-described operation repeated.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by any-one of the following claims or the equivalent of such stated means be employed.
