UNITED STATES CHARLES H. NEVVHALL AND MILES PATENT OEEICE.

H. RAY, OF PROVIDENCE, RHODE ISLAND.

SPECIFICATION formingpart of Letters Patent No. 613,593, dated November 1, 1898.

Application filed October 30, 1897.

To all whom t may concern:

Be it known that we, CHARLES H. NEWHALL and MILES H. RAY, citizens of the United States, residing at Providence,in the county of Providence and State of Rhode Island, have invented a new and useful Coin-Controlled Tire-Inater, of which the followingis a speciiication.

Our invention relates to slot-machines, and more particularly to a machine to be actuated by the dropping of a penny or other coin in a slot to open a valve to admit air under pressure to pneumatic tires.

The object of our invention is to furnish to bicycle dealers and others a machine which without attention may be used to inflate the pneumatic tires of bicycles and like vehicles by the rider thereof, the machine being actuated to open the valve by the dropping of a penny or other coin into the slot.

Vith this object in View our'invention consists in a reservoir for the reception and holding of a supply of air under pressure, a pipe leading therefrom to a valve-cylinder incloscd within a casing, mechanism also inclosed within the casing whereby a coin dropped into the slot in the casing becomes substantially part of the plunger by which the valve is opened, and an outlet from the valve-casing provided with means for attachment to the valve of the tire.

Our invention further consists in the improved construction, arrangement, and combination of parts hereinafter fully described and afterward specifically pointed out in the appended claims.

In order to enable others skilled in the art` to which our invention most nearly appertains to make and use the same, we will now proceed to describe its construction and operation, reference being had to the accompanying drawings, forming part -of this speciiication, in which- Figure l is a View in elevation, illustrating an intiating outfit equipped with our improvements. Fig. 2 is a sectional View, on an enlarged scale, of the valve and its operating mechanism. Fig. 3 is a detail view in elevation, on an enlarged scale, of the valve-operating mechanism. Fig. 4 is a detail perspective view of the coin-operating mechanism.

Serial No. 656,928. (No model.)

Fig. 5 is a vertical sectional view through the coin-operating mechanism. Fig. 6 is a transverse section through the same.

Like letters of reference mark the same parts wherever they occur in the various figures of the drawings.

Referring to the drawings by letters, A is a reservoir of any approved construction to receive and store air under pressure from any suitable source, such as an automatic airpump, a delivery-pipe A2 also leading from said reservoir, the reservoir being furnished, if desired, with a pressure-gage of any ordinary construction to indicate the pressure of the air Within. The delivery-pipe A2 leads from an opening B, through a box or casing B, into a valve-cylinder O, and from such valve-cylinder projects a delivery-pipe D, which may be provided with a suitable nozzle A3 to connect it with the tire A4 to be iniiated.

A slot E through the top of the box B leads to a channel between plates F and Gr, the latter of which rests against the side of the box or may be the side of the box itself, the former being secured thereto by screws H, the plates being a sufficient distance apart to permit a coin-as, for instance, a pennyto pass through the slot and down between the plates into a position to rest in the rear of two springs I, secured by two of thev securing-screws F.

Extending from the plates F and G are rods or bars K and K', connected by short iiat links L at their outer ends, leaving a space between the links L for the passage of a plunger M, which projects outside of one end of the casing and is provided with a pushbutton N.

A spring O, coiled around the plunger and bearing at one end against the plates F and G and at the other end against a pin P, serves to hold the plunger normally in its outer position, it being prevented from being pushed too far out by the pin P engaging the links L.

A coin-passage leads laterally from the point at which the penny engages behind the springs in line with the plunger M, so that when a penny has been deposited and has dropped to said position of rest behind the springs pressure inward upon the plunger M will push the coin along in advance of it through said coin-channel and against the head R of a valve-stem R, carrying a valve S, which engages a valve-seat S in a diaphragm centrally located in the valve-cylinder C between the air inlet and outlet, and is normally held closed by a spring T. The valve having been opened by the inward pressure of the coin, air is permitted to pass through the valve-cylinder and the pipe D into the tire and will continue to pass into the tire until :it is fully inflated, when by releasing the pressure on the plunger Mit will be thrown by the spring O into its normal outer position, which will leave the penny free to be pushed back in the coin-channel by means of the valve-stem impelled by a spring T, as before stated. Independent of this, however, the coin-passage is inclined and the coin would usually roll back without such pressure.` When the coin reaches the ends of the springs I, it will not pass behind them into its old position for the reason that their ends bear tightly against the inner plate G, but it will roll over the outside of the springs and drop into the box or casing, there to remain until removed by a properlyauthorized person. The pressure of air in the reservoir will always be maintained by the automatic air-pump before referred to, but not shown.

While we have illustrated and described the best means now known to us for carrying out our invention, we do not wish to be understood as restricting ourselves to the exact details of construction shown and described, but hold that any slight changes or variations, such as might suggest themselves to the ordinary mechanic, would properly fall within the limit and scope of our invention.

IIaving thus fully described our invention, what we claim as new, and desire to secure by Letters Patent of the United States, is-

l. The combination with the box or casing, of the Valvecylinder, provided with a central diaphragm forming a valve-seat, an in let-pipe communicating with one section and an exit-pipe communicating with the other section of the valve-casing at opposite sides of the central diaphragm, a spring-impelled valve-stem, carrying a valve to engage in the valve-seat, and a coin-controlled mechanism whereby the valve-stem is pressed inward to release the valve, substantially as described.

2. The combination of the valve-casing, its valve and valve-stem, its inlet and outlet pipes, with the coin-controlled mechanism provided with a slot in which to drop a coin, a plunger in line with the coin when dropped into the slot, and a spring for holding the coin in line with the plunger, substantially as described.

3. The combination in a coin-controlled a pparatus, of two plates having a coin-slot and coin-passage between them at an angle to each other, springs located at the junction of the coin-slot and coin-passage adapted to hold the coin dropped into the slot, their outer ends bearing against the inner plate beyond the coin, a spring-retracted plunger in line with the coin, a valve-casing, and a valvestem projecting from the valve-casing in line with the plunger and coin, substantially as described.
