SPECIFICATION forming part of Reissued Letters Patent No. 12,373, dated July 18, 1905. Original No. 699,191, dated May 6, 1902. Application for reissue filed August 24, 1903. Serial No. 170,612.

to which is connected the piping 16, leading to the parts to which oil is to be delivered. Astufhng-box I7 is located at the upper end of the cylinder.

Upon the shaft 4 is pivoted an arm 18, from which extend two projections 19 and 20. A screw 21 has a connection with the projection 20.

To the arm I8 is pivoted a lever 22, which is located between the projections 19 and 2O of the arm 18. This lever has a series oi holes 23. A dog 24 has a pivotal connection with the arm 18 near its free end and engages the teeth oi' the ratchet-wheel 6. A rod 25 has a pivotal connection with the lever 22 and passes through an opening in an extension 26 oi the dog 24. A coiled spring 27 surrounds the rod 25, one end pressin against the eX- tension 26 and the other en against the eye of the rod at its point of connection with the lever. A iiat spring 28 is supported by the oil-reservoir and bears against the inner face of the ratchet-wheel.

With the parts in the position shown lat To all whom, it 11m/y concern:

Be it known that I, OLIVER G. KIPP, a citizen oi the United States, residing at Madison7 in the county of Dane andState of Wisconsin, have invented certain new and useful Imrovements in Lubricators, of which the folowing is a specification, reference being had therein to the accompanying drawings.

This invention relates to improvements in 1o lubricators of the sort in which a positive feed is secured and the quantity of oil delivered is under complete control.

In the accompanying drawings, Figure 1 is an isometrical representation of my improved I 5 lubricator. Fig. 2 is a partial side elevation, the cylinder being in vertical section and the slot in the piston in communication with the oil-reservoir. Fig. 3 is a horizontal section on dotted line a, Fig. 2. Fig. 4 is a partial 2c side elevation, the cylinder being in vertical section and the piston at the upper end of its stroke. Fig. 5 isa horizontal section on dotted line l), Fig. 4. Fig. 6 is a partial side elevation, the cylinder beingV in vertical section 2 5 and the piston at the lower end of its stroke and in communication with the dischargeopening. Fig. 7 is a horizontal section on dotted line c, Fig. 6. Fig. 8 is an end elevation of the actuating means. Fig. 9 is an 3o isometrical representation of the piston.

The oil-reservoir l has an opening in its Vtop closed by a cover 2. From the upper end oi this reservoir extend two brackets 3, which support a shaft 4. In the lower end of the reservoir is located an oil-outlet 5. To one end oi the shaft 4 is secured a ratchetwheel 6, and to the other end of the shaft is secured an eccentric 7, supporting a strap.8. The eccentric is located diagonally to the` 4o lengthwise direction of the shaft.

To the strap 8 is pivoted a yoke 9. The yoke is secured to a rod I0, having a connection with a piston 11 by a universal joint 12. The piston 11 has a lengthwise slot 13, lo- 4 5 cated to one side oi the center of the piston.

vA cylinder 14 is secured to one side of the oil-reservoir and has a threaded extension 15 Jfullest extent, and the opening 13 in the piston will communicate with the opening lea ing from the cylinder into the oil-reservoir. Ii' movement be imparted to the lever 22, it will move the arm I8, and through the dog 24 an intermittent rotary movement will be imparted to the ratchet-wheel 6 and through the shaft to the eccentric. The intermittent rotary movement imparted to the eccentric will be imparted to the piston and in moving Jfrom the position shown at Fig. 2 to the position shown at Fig. 4 will raise the piston and draw in a charge of oil Jfrom the oil-reservoir, at the same time gradually turning the piston until the opening 13 is parallel to the aXis of the openings 5 and 29. This completes a quarter-revolution of the eccentric. Another quarter-revolution of the eccentric will turn the piston as shown at Figs. 6 and 7-that is, the piston will have partially rotated-so that the opening 13 will communicate with the oil-discharge opening 29 and Figs. 2 and 3 the piston will be down to its Y tially rotate the piston shown at Figs. 6 and 7 shown at Figs. 2 and 3, v

When the and the oil-opening leading voir, it acts as a valve munication with the outl piston is in the positi IO when the piston is in communication with et-openmg29 communication is cut ofl the outl with the opening leading The eccentric movement, in combination with the movement imparted by the eccenlocated at an oblique i reciprocate the piston at the same time give the oscillatory half-revolution of the tric owing to it being angle to the shaft, will and movement during one shaft and w' give it movement without reciprocation during the other half-revolution.
