VELOCIPEDE.
SPECIFICATION forming part of Letters Patent No. 488,988, dated January 3, 1893. Application tiled November 10,1891. Serial No. 411,430. I(No model.)
To all whom it may concern..-
Be it known that I, OSCAR DALISCH, a citi-.
`zenfof the Kingdom of Prussia, residing at Neisse,intheProvince of Silesiaand Empire of Germany, have invented certain new and `useful Improvements in Veloci pedes, of which means consist of a reservoir containing com-l pressed air, liquid carbonic acid or asimilar material which is allowed to act upon the driving shaft .and which is controlled -by the pecnliarlmechanism hereinafter specified.
I In the accompanying drawings Figure'l is an elevation of a veloci pede provided with my improvement. Fig. 2 a rear view thereof. Fig. 3 a longitudinal section through the, cylinder. Figs. 4 and 5 are similar sections with the cut off in diierent positions. Fig. 5 a diagram showing the reversal of motion and Fig. 6 a section through the piston showing the cut 0E mechanism. Figs. 4 6, are drawn on a larger scale than the remaining figures.
The letter a, represents a suitable reservoiror tank secured tothe frame of a velocipede preferably between its driving wheels. This reservoir is adapted for the reception of compressed air, steam or liquid carbonio acid` and is connected to a cylinder b, by means of the inlet pipe Z. pulley c, which by means of chain c', revolves pulley d, fast on driving axle d. Within the pipe Z, there is a throttle 'valve which can be` operated by Ameans of rod e. This pipe may also be' provided with a pressure reduction valve or with an expansion chamber, .to convey the compressed air &c. under the proper tension and condition into the cylinder.
m, m', are the valve boxes, containing the inlet spring valves fn, n. The piston rod b', is tubular and is set into a socket of the pistou b2. Through the bore of the piston and the hollow piston rod there extends a valve rod '0,which is pivoted to a cross piece p, sliding in slots of the piston rod. The cross piece p,
'oted a forked lever r, connected to a lever s,
The piston rod b', revolves is held bya turnable sleeve q, to which is pivthat may be revolved on the connecting rod or pitman t. This rod is coupled tothe crank u', of axle u, (Fig. 3).
The piston b2, is provided with the double valve e, which is adapted to be opened or closed by coming into contact -with the-cylinder heads and which allows .the air in front of the piston to be exhausted through the bore e', and the hollow piston rod b. In the position shown in Fig. 3, the pin o', of valve 6o rod o, (which is'placed in alignment withthe valves fn, ln!) opens the valve fn, to admit the compressed air behind the piston. The piston will now move forward and the pin Q will keep the valve n., open fora short time r,by a differential movement of the rod o, in the piston rod. At the end of the strokethe valve v, will be reversed and the valve n. will be opened so that the return stroke is made. By revolving the levers r, and s, one hundred and eighty degrees (Fig. 5) it is possible to give to the machine a reverse motion. If these levers are revolved while the velocipede is driven, one ,of the valves n, n', is opened prematurely and a contrary pressure will arise before the crank arrives at its dead point. This causes the piston to stop and go back so as to give to the machine the desired reverse movement.
What I claim is:
1. The combination of reservoira with cylinder b, inlet valves ln, fn', piston having valve "v, hollow piston rod and with valve rod o having pin'o, substantially as speci tied.
2. The combination of reservoir a with cyl- 85 Signed at Breslau, in the Province of Silesia 9o and Kingdom of Prussia, Empire of Germany, this 22d day of October, 1891.
