COIN-OPERATED DEVICE FOR BICYCLE-PUMPS.

SPECIFICATION forming part of was meet No. 655,108, dated July 31, 1900. Application filed December '7, 1899- fierial No. 739,542. (No model!) ,To aZZ whom it may concern.- 7 Be it known that I, THOMAS PALMER, citizen of the United States, residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in Coin-Operated Devices for Bicycle-Pumps; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference part of this specification. i

This invention relates to new and useful improvements in slot-machines, and especially to an apparatus designed especially for use in connection with a bicycle-inflating pump, whereby it is necessary to drop a coin into the slot of the apparatus before a'certain valve is allowed to close over the open end of a tube having communication with the cylinder of the pump, which causes the air to be forced through a passage-way, at the end of which connection may be made with the inflatingvalve of the tire of the bicycle.

More specifically,the present/invention con sists in the provision of a slot-machine for use in connection with bicycle-inflating pumps in which it is necessary before the apparatus can operate to drop acoin into a slot, which coin falls by gravity to a position covering an aperture in the free end of a spring-actuated plate, which plate is designed to close over theopen end of a pipe having communication with the interior of the pump-cylinder,'a vertically-operating rod pivoted to the leverpipe on which the rim of the bicycle-wheel restswhile being inflated being adapted to strike against said coin and depress with it said plate.

To these ends and to such others as the invention may pertain the same consists, further, in the novel construction, combination, and adaptation of the parts, as will be herein after more fully describedand then specific ally defined in the appended claims. I My invention is clearly'illustrated-in the accompanying drawings, which, with the letters of reference marked thereon, form a part of thisapplicatiomand in which Figure'l is a side elevation of my slot-machine for operating bicycle-pumps, the cas ing being shown in section. Fig. 2 is a central vertical section through the apparatus. Fig. 3 is a sectional view on line 3 3 of Fig. 2. Fig. 4' is a cross-sectional view onj'line 4 at of Fig. 1 Reference now being had to the details of the drawings by letter, A designates the easing of the apparatus, which is shown'only in section in the drawings. Located infthejcas ing is a' hand-operated air-pump B, with a a piston and plunger of ordinary construction. Leading from the lower end of the cylinder of thepump is a pipe 0, having connected 'there to a union 0, to which union is connected at' right angles to the pipe 0 a vertical pipe D, with its upper end normally open. This pipe D, as shown in Fig. 2, passes through thebottom of the box E, provided to receive the coins which have been dropped in the slot for the purpose of making it possible to use the pump. Connected to the opposite end of the union 0 is a'pipe G which in turn is connected to an elbow C from which risesa vertical pipe G with an open upper end.. For supporting the upper end of said pipeC, I have shown a screw-eye 0 Fig. 1, which is fastened'to the frame of the apparatus.

Mounted on theupper end of the post F is an apertured plate G, held by means of nuts G to said post. Pivoted to the plate Gis a second plate H, which'has sec'ured'to its" under surface a rubber valve H, designed when said plate H is depressed to close over the upper end of the pipe D and prevent theescape of any air through said pipe D. A spring I, bearing between the adj usting-nut LFand the undersurfaceof the valve H, serves to throw the plate H up, so that the valve H- will normally clear the upperend of the vertical pipe D, in which position the apparatus would be inoperative. On the upper surface of the plate H is a hopper J, the upper face of the plate forming the bottom of the hopper, and directly over said hopper is the outlet end of the chute K, having an opening K, through which the coin, which is dropped into the upper end of the chute, falls by gravity onto the upper surface of the plate H and into the position shown in Fig. 2, coveringtheaperture h, the coin beingdesignatedin said fig ure by letter N. One side of the hopper, which receivesthe coins, is cut away and has adown' wardly-disposed slide H, Fig. 1 of the draw ings, down which the coins slide into the renormally at its highest limit by means of the spring P, Fig. 1, whichbears between the cross-piece of the apparatus and the lug 0 carried by the lever O. Pivoted to the lever O at Q is a short socket member Q, the lower end of which is internally threaded to receive the upper endoof the rod B, the lower end of which passes between the plates q and -nor-' mally, when depressed by the lowering of the i leverO, adaptedto pass through the. aperture h in the plate H. Mounted on.a pin L,

carried between the plates q, is a lever'L,

the lower end of which is connected to a spring L which spring is in turn fastened to an apertured plate L carried overthe pipe D and held between the two nuts L the office of this spring L being to normally hold the lower end of the lever L against the free end ofthe pivoted plate H or against the edge of the coin N, which may project a slight distance beyond the edge of the plate H when the rod R is forced down on the upper face of sa d co [A portion of and-mounted on saidthreads are two adj usting-nuts r, between which is held a plate of rectangular shape R which is longitudinally slotted to receive the upper free end of the lever L. lhe upper end of the lever L is laterally bent, as at L and slotted, as at L, and to the walls of said slotted portion is held a pin Z, on which is mounted a dog Z, which is normally held in the position shown inF-ig. 2 by means of the spring 1*. This spring has one end secured to the upper end of the lever L and is bent forward, with its free end bearing against the upper edge of said 'dog at a position slightly behind its pivotal point. As the plate R is depressed the underside of the latter near its outer end'strikes against the upper edge of the dog near-.itsouter end and the latter tilts idly, and after the plate R has passed below the dogthe latter is returned to its normal or horizontal position under the action of the spring Z When the plate R returns to its normal or highest position, the upper edge of said'plate strikes against the under side of said dog near the outer end of the latter. As the dog begins to tilt its rear end on the under side will strikeagainst the bevel surface forcibly against the edge of the coin which has been previouslydropped downthe chute and rests over the aperture h in the end of the hopper J and kick against said 'coin with suffithe rod R is threaded, as at r,-

oient force to knock it. out oifthe hopper, causing said coin to slide down the inclined way and into the receiving-box beneath.

The outer end of the lever O is preferably rounded and hasa central bore Q which terminates at a point opposite the upper end of the pipe 0 Leading into and communicating with the bore Q at its inner end is a nipple Q about which is a rubber cushion Q which abuts against the upper end of the pipe C? as the nipple ente-rs the bore of said pipe; The weight of the wheel resting on the outer end of the lever'O will exerta sufficient pressure on'the cushion Q, so as to make an air-tight joint.

Near the outer end of the rod 0 and seated in a recess at right angles to the bore Q Fig.

4, is a nipple Q", Which is surrounded by a rubber cushion Q On opposite sides'of the cushion Q are the curved plates Q held to the bar 0 by means of suitable screws, as shown,.these plates being provided for the purpose of holding the upper end-of said nipplc and cushion securely.

In operation a coin is firstplaced in the chute K. The said coin,.falling by gravity, will stop in, the position shown in Fig. 2, in which position the coin rests over the aperture h. The rim of the wheel, the tire of which is placed over the end'of the lever 0, causes said lever to be depressed, and with it the rod R, which strikes against theupper surface of the coin and depresses the pivoted plate H downward a sufficient distance so that the valve H will close over the upper end of the pipe D. When the valve H is in its seated position, the nipple Q is positioned in the bore at the upper end of the pipe (3, and the cushion Q bears air-tight against the upper end of said pipe, and the air-passage 'from the pump to the tire is uninterrupted.

The in flatin g-valve of the tire is held over the nipple Q before the pump is operated by hand. When the tirehas been inflated and the wheel removed from the end'of the lever O, the spring P will cause the lever O to resume its normal position, which is at its highest throw. On the return upward'movement of the plate R its outer upper edge strikes against the under side of the outer portion of the dog, and the lever L" will be caused to tilt, its lower end being thrown out a sufficient distanceto allow the plate R to pass the dog Z, after which the springL? will fluence of thespring L'return to its normal position and the valve H will be unseated.

In case it is attempted to inflate the tire without first dropping a coin in the chute the result wilLbe that the lower end of the rod R will pass through theaperture h and the pivoted plate H will remain idle, and consequently the valve carried thereby will remain unseated. The lever L, it is true, is actuated at each depression of the rod R and kicks against the end of the pivoted plate, but accomplishes no result unless a coin has been previously dropped into the chute.

It will be observed upon reference to the drawings that in order to make the piston of the handpump operate easily I provide a valve in the lower end of the cylinder of the pump, said valve resting in a suitable cup or socket, and as the piston is raised the air is allowed to enter an aperture, which is closed.

by the valve as the piston is pushed down.

Having thus described my invention, what I claim to be new, and desire to secure by Letters Patent, is-

1. A coin-operated apparatus for bicyclepumps comprising in combination with an airepump, open-ended pipes communicating With the cylinder of the pump, a pivoted lever having a bore in one end, a nipple leading into said bore, adapted when said lever is depressed, to communicate with one of said open-ended pipes,-and means for closing the open end of the second pipe communicating with the air-pump, as said lever is depressed.

2. A coin-operated apparatus for bicyclepumps, comprising in combination with the pump, open-ended pipes communicating with the pump-cylinder, a lever pivoted to a suitable support, and having a bore in its outer end, a nipple leading into and communicating with said bore, and'positioned opposite the upper end of one of said open-ended pipes,

a pivoted plate carrying a valve, and means for seating said valve as the lever is depressed, as set forth.

3. A coin-operated apparatus for bicyclepumps, comprising in combination with the pump, open-ended pipes communicating with the cylinder of the pump, a pivoted lever hav- I pivoted plate and in the path of said rod, to depress said plate and means for removing the coin fromsaid plate, as set forth.

4. A coin-controlled apparatus for bicyclepumps, comprising in combination with the pump, the open-ended pipes communicating with the cylinder of the pump, a pivoted 1ever having a bore in one end a nipple leadinginto and communicating with theinner end of said bore, said nipple being positioned opposite the end of one of said open-ended pipes, a pivoted plate spring-actuated and having a valve on its under surface adapted to be seated over theupper end of the second of said open-ended pipes, a rod pivoted to said lever, the lower end of said rod designed V to strike against a coin, that has been previously deposited near the free end of said pivoted plate, whereby the latter is depressed and the valve carried thereby seated, and a sprin -actuated lever designed to kick the coin off from said plate, as the rod is raised,

as set forth.

5. In a coin-controlled apparatus for bicycle-pumps, the combination with the pump,
