Patented Aug. 8, 1905.

Application filed August 1, 1903. Serial No. 167.935.

T0 aZZ whom, it may concern.-

Be it known that I, OLIVER G. KIPP, a citizen of the United States, residing at Madison, in the county of Dane and State of Wisconsin,

have invented certain new and useful Improvements in Lubricators, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to improvements in lubricators of the class in which a positive feed of the oil is attained and the quantity thus delivered is under control, it relating more particularly to improvements of the sort illustrated in the Patent No. 699,191, issued to me May 6, 1902.

In the accompanying drawings, Figure 1 is a front elevation of my improved lubricator. Fig. 2 is a side elevation. Fig. 3 is a view, partly in side elevation and partly in section, of the pump-cylinder and piston. Fig. 4 is a horizontal section on the line a: a; of Fig. 3. Fig. 5 is a view partly in elevation and partly in vertical section. Fig. 6 is a horizontal section on the line y y, Fig. 5. Fig. 7is a view, partly in side elevation and partly in vertical section, showing the piston when the eccentric has'been rotated approximately one hundred and eighty degrees fromits position in Fig. 3. Fig. 8 is a horizontal section on the line 2 .2, Fig. 6. Fig. 9 is an elevation of the driving device. Fig. 10 is a perspective of part of the piston.

The oil-reservoir 1 has an opening in its top closed by a cover 2. From the upper end of this reservoir extend two brackets 3 3, which support a shaft 4. In the lower end of the reservoir is located an oil-outlet 5. To one end of the shaft is secured a ratchet-wheel 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 lengthwise direction of the shaft.

To the strap 8 is pivoted a yoke 9. The yoke is secured to a rod 10, having a connection with a piston 11 by a universal joint.

I have devised a peculiar connection for the yoke 9 and the eccentric-strap. I join them by trunnions or hinges 30, fitting eyes 31 at the ends of the yoke 9. The axis 32 of this hinge connection lies in the horizontal plane of the axis of the shaft4 or in approximately horizontal planes near it and vibrates in said planes around the vertical axis of the piston passing through the axis of shaft 4. This is in contradistinction from the method of hinging these parts together previously devised by me and illustrated in my aforesaid Patent In the earlier mechanism I hinged or pivoted the fork to the lower part of the eccentric-strap 8, there being a downward projection from the said eccentric-strap to receive the pivot. When thus pivoted, the pitman-rod 10 was vibrated through a long are and had two swinging movements, out and in, imparted at each revolution of the shaft. Moreover, the vertical play of the hinge-axis of the rod 10 was increased by this movement.

In the present construction the hinge-axls is raised and lowered only slightly, the distance being equal to the eccentricity of the eccentric less the loss, vertically, due to ts inclination. The connecting-rod 10 remains approximately vertical at all times, and the power is applied to the piston economically and on proper lines, there being an avoidance of all side thrust or torsion. The movements are entirely uniform and smoothly efl ected.

The piston has a lengthwise slot 13, located to one side of the center of the piston. It will be observed by reference particularly to Figs. 4, 6, 8, and 10 that this slot 13 is so disposed relative to the inlet-duct 40 and the outlet-duct 41 in the cylinder 14 that it never communicates with both ducts 40 and 41 at the same time, Fig. 6, both ducts being momentarily cut off from the slot in the piston before communication is established with either one. As is understood, the piston 11 by reason of its construction and the fact that it has imparted to it oscillatory movements acts not only as a piston, but also as a valve and the disposition of the slot as described permits the lubricator to feed against a considerable pressure with no other valve arrangement than the oscillating piston 11.

A cylinder 14 is secured to one side of the oil-reservoir and has a threaded extension 15, to which is connected the piping 16, leading to the parts to which oil is to be delivered. A stuffing-box 17 is located at the upper end of the cylinder.

Upon the shaft 4 is pivoted an arm 18, from which extend transversely two projections 19 and 20, approximately parallel to the shaft.

- 7 forth.

A screw 21 has a connection with the projection 20.

To the arm 18 is pivoted a lever 22, which is located between the projections 19 and 20 of the arm 18. This lever has a series of holes 23. A dog 24L has a pivotal connection with the arm 18 near its free end and engages the teeth of the ratchet-wheel 6. A rod 25 has a pivotal connection with the lever 22 and passes through an opening in an arm 26 on the dog 2 A coiled spring 27 surrounds the rod 25, one end pressing against the extension 26 and the other end against the eye of the rod at its point of connection with the lever. I

In the earlier construction I provided a friction-holder for the ratchet feed-wheel. I have devised a superior arrangement of parts for locking the wheel, which is herein shown. The bracket 3 is extended upward to form the arm 3", and at its upper end it supports a positively-acting dog 6. After the thrustrod is moved and the lever 22 and through the dog 2 L has caused the ratchet-wheel to advance the latter is positively locked against retraction by the devices at 6 3 What I claim is 1. In a lubricator, the combination of an oil-reservoir, a cylinder having inlet and outlet ports for the oil, a longitudinally reciprocating and oscillating piston having a passage-way for oil therethrough adapted to be alternately brought into communication with said inlet and outlet ports, a driving-shaft, an eccentric rotating with the shaft and held at an inclination thereto, the eccentric-straps and a power-transmitting rod between the eccentric-straps and the piston and pivotally connected to the eccentric-straps at an axis lying in a plane passing through the axis of the driving-shaft approximately perpendicular to the piston, substantially as set 2. In a lubricator, the combination of an oil-reservoir, a cylinder having inlet and outlet ports for the oil, a longitudinally reciprocating and oscillating piston having a passageway therethrough for oil adapted to be brought into communication alternately with said inlet and outlet ports, a rotating eccentric supported in a plane oblique to its axis of rotation, the

eccentric-strap and a power-transmitting rod connected to the piston and pivotally con- I nected to the eccentric-straps on an axis in the plane passing through the axis of rotation of the eccentric, substantially as set forth.

3. In alubricator. the combination of an oilreservoir, a cylinder having inlet and outlet ports for the oil, a longitudinally reciprocating piston having a passage-way for oil therethrough adapted to be alternately brought into communication with said inlet and outlet ports, a rotating eccentric held in planes inclined to the axis of its rotation, a strap or loop engaging with said eccentric, and a powertransmitting rod connected to the piston and hinged to the strap on an axis intersecting the axis of rotation of the eccentric, substantially as set forth.

4:. In a lubricator, the combination of an oil-reservoir, a cylinder having inlet and outlet ports for the oil, a piston in the cylinder having a passage for the oil therethrough adapted to be alternately brought into communication with the inlet and outlet ports of the cylinder, a driving-shaft, an eccentric on the shaft inclined thereto, a strap surrounding the eccentric and within which the latter turns, provided with diametrically opposite pivots disposed in a horizontal plane that approximates the horizontal plane of the axis of the shaft, and a power-transmitting rod connected with the piston and also with the said pivots of the eccentric-strap, the piston being so disposed that its longitudinal vertical axis passes through the longitudinal axis of the drivingshaft, substantially as set forth.

5. In a lubricator, a pump like device, having a cylinder with a lubricant-chamber and with an inlet and an outlet duct, and a longitudinally reciprocating and oscillating piston in the cylinder, the piston being provided with a lengthwise slot arranged to have constant communication with the lubricantchamber in the cylinder and to successively communicate with the said inlet and outlet ducts, but when occupying a mid-position to be entirely cut off from them both, substantially as set forth.

In testimony whereof I aflix my signature in presence of two witnesses.

OLIVER G. KIPP.
