A second piston 16 is provided to new und useful llorce-leed iler, of which lit snugly into the here 13 and lies e reduced the following is e specilication. lower end 17 to lit snugly into. the bore ll.

Similar reference characters .referto snnil ln operation the piston l2 Iis moved up 'ler parte throughout the several views. and clown from its lowermost position to its n"he operating mechanism is contained .in uppermost position und back to its lowers suitable oil receptacle 6, having the hotroost position, continually.

The continued upward. cylinder and its cooperative parts. Promovement of piston l2 will :torce the oil out from between the bottom 2O o'bore 14- and the lower end 19 of reduced piston portion 17 into passage 27, from whence the oil passes out at drip spout. 28 and into passage 21; and at the same t-ime'the continued npward movement. of piston l will forge the oil out. from between the otset'ltS/and offset. 15 into the passage QG. moves down again the piston 16 will move downward with it until the screw nut 30 contacts with the top 9; the continued downward movement of piston 12 will` by means ot the vacuum created, draw oil int-o the space hetwecn the bottom 2O of bore 1-l and the lower extremity 19 ot reduced piston portion 1T. Thus it` will be seen that. the oil is drawn 'fronrwithin receptacle. 6, is forced through passage QT, drips at' QS into passage Q-lfrom whence it is drawn and forced out through passage QG from whence it is directed by means of piping 33 to any desired locality.

A trans-pa rent protecting cap over the. exposed parts ot passages QT 34 is secured and 24 to exclude. all foreign matter and permit. i

While any dcsired n'eans maiY be employed to reciprocate the pistony l departing from the spirit of my invention, I have shown a novel and suitable mechanism to cause. said movement which comprises a horizontal shaft. 35 mounted in suitable bearings rigid with cylinder 10, and having mounted rigidly thereon two eccentric. ams 3G which operatively engage the slotted levers 37 .pivotally mounted at 3S to brackets rigid with cylinder 10. 'libe free end ot' levers 37 are connected by links 39 to a bar or shaft 4t) which extends through a hole provided thcrctor in the lower end of pistons 12. The parts are so arranged and connected that as the shaft 35 is rotated the pistons 1'2 will be rcciprocated longitudinally.

Loosely mounted on shaft 35 is a worm gear 4l which meshes with the worm l2 bearings rigid with the receptacle (i, said shaft. having` one end extending to the exterior of said receptacle 6 where power is ap'plied to the same from any source desired. rigidly secured to the shaft. :l5 adjacent to gear 'l1 is a collar 4l; which is provided with notches into which a spring pressed latch l5 sldably mounted in th'e'hub of gear 4l takes, in such manner that; when the gear 4l rotates in one direction it will hy reason,

ol latch 45 carry the collar :it and therefore, the shaft B5 around with it, but it the ;'ear ll rotates -in the ot-l'ler direction the latch #l5 simply Clicks over the notches in collar il and said-collar and shaft 35 are not. rotated.

While we have shown and described a construction and Jform which at presentV is\con sidcred the best, we may find from further experience that a change in the general arrangement and form ot' parts ma)v imi'wrove the device. which chantre maiv bc made without departing' from the scope of the invention as pointed out in the appended claims..

llaving thus tully described our invention what we claim as new and desire to secure b v Letters la'tent ot the lfnited States istl. ln a device of the class described, a cylinder open at' both ends. a hollow piston ha ving' one end closed to reciprocate in said c vlindcr, a second piston to num` in said hollow piston.y a port in said first named piston forming colmnunicathn between the interiorand exterior of said piston to cooperate with two ports through the cylinder, ahutments on the second named piston to engage a stationarv.' part' to limit the movement. of .said piston and means whereby lost motion is provided between said second named pistonvand the stationair)v part.

ln a dcvicc of the class described, a stationary c vlinder open at hcth ends, a piston fitted to move in said cylinder, a, large and small longitudinal bore in one end oi said piston, a second' piston having' a large and a small portion to tit and move in the bores ot said lil-st named'piston. a port in said first inlined piston leading,r from the exterior to the small bore, a .sccond por` in said first named piston leadizrer 'from the exteriorto the large llore. three internal passages in :said cylinder to cot'ipcralc with said ports in said piston and-means to reciprocate said first. named piston.
