PUMP ATTACHMENT FOR BICYCLES.
SPECIFICATION forming part of Letters Patent No. 559,418, dated May 5, 1896.
Application filed September 23, 1895. flerial No. 563,301. (No model.)
T0 whom, it may concern: 7
Be it known that I, LLOYD G. SPENCER, of Chicago, in the State of Illinois, have invented certain new and useful Improvements in Pump Attachments for Bicycles, of which the following is a specification.
My invention relates to automatic pump attachments for bicycles; and the object of my improvements is to provide an attachment supported on the hub of the bicycle-wheel and having a gear connection with the spindle whereby the pump can be operated by the revolution of the bicycle-wheel for the purpose of inflating the hollow elastic tire. I attain this object by the means illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of a fragment of a bicycle wheel and frame with the pump is a top view of a similar fragment. Fig. 3 is a detail showing a fragment of the frame which supports the pump and the pump-opcrating wheel in section. Fig. 4 is a detail showing a longitudinal section ofa fragment of the tube leading from the pump, and the overflow or safety valve in connection there with.
In the drawings, A designates the rim of the bicycle-wheel with the inflatable tire in connection therewith, and a wire spokes in connection with the hub A and rim, all of ordinary construction.
B is the frame of the machine.
0 is the pump-frame, which comprises parallel bars 0, connected by a cross-bar c and clamping -pieces 0 whereby said frame is clamped and fixed rigidly to the hub of the bicycle-wheel.
I) designates the pump-cylinder, which has an open end secured to the parallel bars of the pump-frame by means of screws or rivets cl, so as to be firmly supported on said frame. The cylinder is provided with a tube or pipe d.
E designates a valved air-induction tube which passes through the rim and communicates with the inflatable tire in the ordinary manner, and the pump-tube d is connected with the valved air-induction tube by means of an extension d which is preferably a short section of elastic tubing adapted to be expanded so as to form a lap-joint in connection with the joined parts. The cylinder is pro- .prevent the air from passing the piston when moved in the opposite direction. The pitman F is pivoted to the piston-rod e at one end and mounted on a crank f at the opposite end, said crank being connected with a shaft f, j ournaled in a projection 0 upon the pumpframe.
The gear-pinion Gis mounted loosely on the shaft f and has a groove g, extending nearly through the hub of said pinion and adapted to engage the spline f which is fixed to said shaft along a portion near its outer end, so as to enter said groove and hold the pinion rigidly fixed to said shaft when turned so as to bring said groove into registration therewith. A spring l-I, interposed between the So projection o and the end of the hub, is adapted to hold said pinion upon the spline when in engagement therewith. When thus fixed to said shaft, the pinion is brought into the position in which it is shown in dotted lines in 8 5 Fig. 2 and engages'with a cog-wheel G, which is fixed to the spindle upon which the bicyclewheel hub revolves, so that the pinion G, which is carried round in a circular orbit by a movement of the bicycle-wheel, will thus 0 be made to operate the pitman for working the pump, the crank and pitman playing between the parallel bars 0 of the pump-frame.
The pump-frame is connected with the bicycle-wheel hub so as to come between the 5 spokes shown in Fig. 2, the projection 0 extending out between the spokes so as to sup port the pinion G just outside the spokes. The pump-pipe cl is provided with a springpressed safety-valve d which is made ad- I00 justable bymeans of the screw-plug 01 so that the Valve may be regulated to a certain pressure or varied therefrom, when desired. By
this means the flexibility of the inflatable tire is made adjustable, and the maximum limit of pressure therein may be fixed to correspond with the resistance offered by the safety-valve, as the pump will not force air into the tire when the pressure of the pumptube becomes greater than the resistance of the safety-valve.
The operation is as follows: The tire being in a collapsed condition the pinion G is turned into engagement with the spline f and with the wheel G, in which position it will be held by the spring H. The pump can then be 0perated by revolving the bicycle-wheel until the pressure is raised to a point where it will lift the safety-valve and allow the air to blow off thereat. Then the pinion G is shoved back and partially revolved, so that the groove 9 will be out of line with the spline f and will rest against the end of the hub and so hold said pinion out of gear until another pumping operation is required. It is contemplated that a pump of the character described will be attached to each of the bicycle-wheels in the manner shown, the pump and its frame attachment being made very light and disposed of between the spokes, so as to be out of the way and not interfere with the operation of the wheel when the pump is not in use.
pinion having an internal grooving being loosely mounted upon the crank-shaft and adapted to slide automatically into engagement with a spline fixed upon the crank-shaft when the internal groove is turned so as to register with the spline, and a cog-gear fixed to the axle of the bicycle-wheel so as to mesh with the spring-pressed pinion when moved into engagement with the spline as specified.
