WILLIAM H. PUTNAM, OF MADISON, WISCONSIN, ASSIGNOB T0 MADISON-KIPP LUBRI- CATOR COMPANY, OF MADISON, WISCONSIN, A CORPORATION OF WISCONSIN.
FORCE-FEED LUBRICATOR.
Specification of Letters Patent.
Application filed August 2, 1917. Serial No. 184,105.
Madison, in the county of Dane and State of Wisconsin, have invented a certain new and useful Improvement in Force- Feed Lubrica-tors, of which the following is a specification.
My present invention pertains to force feed lubricators, and has reference more particularly to the provision of means for adjusting and controlling the flow of oil, the means being such as to prevent the parts from being brought into such position as will cut down the amount of oil fed below a pre determined minimum, while at the same time'allowing free adjustment for a greater flow or feed.
In the use of force feed lubricators upon machines, and more especially upon automobiles and tractors, where adjustment of the parts frequently falls into inexperienced hands, there is a possibility of the user adjusting the lubricator so-as to out OK the oilsupply, or reduce it to a point below which it will not effectively lubricate the parts to which the oil passes.
It is the object of this invention to provide an adjustable lock or stop for the feedcontrolling means of the lubricator, preferably inaccessible, which lock may be initially set by one skilled in the art of lubrication and which, While permitting adjustment for greater feed, will prevent such adjustment as would cut the feed down below the established minimum.
My invention is illustrated in conjunction with a lubricator of the type set forth in Letters Patent No. 1,066,238, granted under date of July 1, 1913, to the Madison-Kipp Lubricator Company, as the assignee v of Frank D. Winkley. t

A suitable caslng l is provided in which the workln'g parts are mounted and inclosed,
the upper end of a tube or pipe 3 leading from the measuring pump, the upper end of which pipe is downwardly curved and discharges into a cup 4 mounted upon the upper end of a pipe pump. Pipe 3 at its lower end is in communication with a port 6 formed in the side wall of the cylinder v7 of the measuring pump. Said cylinder isopen at its upper and lower ends, and slidably mounted in the lower end thereof is end of the sleeve being closed by a screw plug 9, While an arm 10 extends laterally from the lower end of the sleeve. Said sleeve is provided with three elongated placed over 5, leading to the force a sleeve 8, the lower R 2 and 13, and said sleeve is de; signed to be adjusted lengthwise in the cylthe lower threaded end of a rod 15. Said rod passes freely through an opening formed in a web 16, and is held against longitudinal movement by stop collars 17, 18, shown as pinched inwardly against flattened portions of the rod and'bearing, respectively, on-the upper and lower faces of the web. Said web'16 is formed integrally with a frame or casting denoted generally by 19, in which the cylinder 7 and also the cylinder 20 of the force pump are formed. As will be seen upon reference to Fig. 1, the member 19 is secured to the side wall of the casing 1 and supports the pump structure Within the casing when submerged in" the oil.
'16, and the lower end A nut 21 is fastened to the lower end "of the rod 15, said nut preventing the rod from being turned entirely out of the 'arm IO when the rod is rotated in that directionto lower the sleeve 8. The lowering of the sleeve increases the capacity of the measur ing pump, and to prevent the sleeve from being raised to such point as would not afford a sufficient feed to properly lubricate the parts for which the apparatus is designed, I provide a stop rod '22. Said rod is mounted in a threaded opening in the web thereof stands in line with the arm 10, or a projection 10 extend ing laterally therefrom. As will be seen upon reference to Fig. l, the rod 15 may be manipulated by the user of the machine. The rod 22, preferably, though not necessarily, terminates within the casing, where it is normally inaccessible, and is provided with a cross slot in its upper end, whereby it may be raised or lowered to bring it to that position which will regulate the minimum amount of lubricant. In other words, the lower end of the rod 22, standing in line with the arm 10, will prevent the operator fromraising the sleeve 8 beyond a predetermined limit and hus prevent the flow of the oil passing through the lubricatorfrom being cut down below a predetermined amount. The rod 22 will be initially set by a person expert in the art of lubrication, so that at no time can the sleeve be elevated to cut oif what would be the ordinary minimum amount necessary for the lubrication of the part which the lubricator is designed to feed.
,lVorking within the sleeve 8 is a hollow piston 23, having the following ports formed therein, to wit, an intake port 2 1, a feed port 25, and an overflow port 26. The upper end of the piston has secured to it a shrouded sector gear 27, adapted to mesh with a sector gear 28, secured upon the upper portion of the piston 29 which works in the cylinder 20. baid piston 29 is provided with a longitudinally-extending feed port 30, and a similarly extending exhaust port 31 upon its side wall at the lower end. Port 30 is arranged adjacent to a port 32 (see Fig. 5) which is in communication with the lower end of pipe 5.. The port 31, when the parts are brought to the positions shown in Fig. 6, registers with a port or passageway 33 which extends through the casting 19 and terminates at its upper end in a delivery pipe 341, leading to the part to be lubricated.
The intake port for the oil is shown in Figs. 5 and 6, and is designated by 35, being an opening extending upwardly through the lower part of the casting 19, thence laterally into the cylinder .7. V
To the upper end of the piston 29 there is secured by a gimbal joint a yoke 36 (Fig. 1). A strap 37 is swiveled in the yoke, said "this construction being similar to that disclosed in Letters Patent No. 796,659., dated August S, 1905. c 1
Through the rotation of the shaft 39 the eccentric causes the strap and yoke to be raised and lowered, and likewise imparts an oscillating movement to the yoke, which mo 7 tion is transmitted to the pistons 23 and 29 through the inter'meshing sector gears 27 and 28. As a consequence, such pistons are raised and lowered and also-oscillated, and through the intake and delivery ports, as above set forth, the oil will be drawn in by themeasuring piston 23 and forced to the sight feed cup e and thence to thepart to be lubricated. by the piston 29. In Fig.5 the parts are shown in a position where the oil is being drawn inwardly by themeasuring pump, and the oil which was previously discharged mto the measuring cup passes -1nto the cylinder 20 through the port 32 and piston port 30.
When the tiOns shown in Fig. 6, uring pump is cut off and the feed port 25 is open; consequently, as the pistons descend the oil which was previously fed into the cylinder 20 will pass outwardly there from through the port 31, port or passage 33, and to the pipe 34. At the same time, the piston 23 will force the oil from the cylinder 7, or more specifically from the interior of the sleeve8, outwardly through the port 6 and pipe 3 and into the measuring cup. so long as the shaft 39 is'rotated. V As above noted, in adjusting the device the expert will turn the rod -2-2'up or down as the case may be, and "as aj'c'ons'equeng e the sleeve 8 cannot be raised within the cylinder 7 beyond a predetermined height and,therefore, the flow .of. oil is never completely shut off. v j
The operator can, :of course, increase the amount of oil above the minimum set, by turning the rod 15 and lowering the sleeve. Thus, in Fig. 2 the member 10, and co'nses quently the sleeve 8, are shown as adjusted between the maximum and (minimum,
