MILDREN, OF PONCA CITY, OKLAH01VIA,'A1\TD ONE-HALF TO W. E. COX, OF TIN-- FIELD, KANSAS FORGE-FEED LUBRrcAroR Application filed February The invention relates to lubricators and more particularly to devices for automatically and positively supplying oil to moving parts of machinery, such as steamand gas engine cylinders, compression and pump cylinders, bearings of every description and moving parts to minimize the friction and wear.

The invention contemplates a container for the oil, a sight gage, a primary pump for delivering oil to the sight gage, so that the feed and the amount of oil supplied may be observed, and an auxiliary or dispensing pump for forcing the oil to the required point of use.

lVhile the drawings illustrate a preferred embodiment of the invention, it is to be understood that in adapting the means to meet specific needs and requirements, the design may be Varied and such other changes in the minor details of construction may be resorted to within the scope of the invention as claimed, without departing from the spirit thereof.

For a full understanding of the invention and the merits thereof, reference is to be had to the following description and the drawings hereto attached, in which,-

Figure 1 is a top plan View of a lubricator, embodying the invention, the cover of the oil container being removed,

v Figure 2 is a vertical sectional view on the line 22 of Figure 1, looking in the direction of the arrows, the cover and sight feed being V in place,

Figure 3 is an elevational view of the lubricator, and r Figure 4 is a detail view of the arm applied to the pump operating rockshaft.

Corresponding and like parts are referred to in the following description and designated in the several views of the drawings by like reference characters.

The container for the oil is designated by the numeral 1 and may be of any capacity,

v wise made fast to the Walls of the container 1,1926. Serial No.- 85,303.

sists of a cylinder and a plunger, the cyLinders being disposed in parallelrelation and connected to a wall of the container. The primary pump is designated by the numeral 8 and the auxiliary, or dispensing pump by the numeral 9. The cylinder of the primary pump 8 is provided in a sidewith a feed opening 10. A pipe 11 projects vertically from the cylinder of the dispensing pump 9 and passes through the cover 2 and terminates within the lower portion of the casing f the sight feed. A pipe 12 projects up-- wardly from an end of the cylinder of'the prlmary pump 8 and its upper end passesthrough thecover 2, and extends into the upper portion of the casing 5 and is recurved and terminates in vertical line withthe pipe 11 from which it is spaced a suitable distance to admit of ready observation of the oil discharging from the upper delivery end of the pipe 12 into the upperjreceiving end of the pipe' 11. The pump '8 includes a plunger 8? and the pump 9 embodies a plunger 9' and these plungers operate in suitable guides 13 secured to the Wall of the container opposite that to-which the pumpicylinders'are connected.

A yoke 14 connects the plungers 8 and9 for simultaneous movement and this yoke terminates inpintles 15 which enter slots 16 in the free ends of arms 17 attached to a rock shaft 18 mounted in opposite sides of the container 1 and having an end extended and provided with an arm 19 which may be connected in any convenientand determinate way with a moving part for operating the device. The operating arm 19 is provided in its length with a plurality of openings 20, whereby the operating part may be adjustably connected thereto. V I

In practice, the container 1 is supplied with oil and the auxiliary, or dispensing pump is connected by means of a pipe 21 with the part, or parts to .be lubricated. The rock shaft 18 is oscillated and through the connections shown and described: imparts a reciprocatory' movement to the pump plungers 8 and 9. Upon the out-stroke of the plu-ngers, the opening 10 and the lower endof the pipe ll-are uncovered and oil passes from theconta-iner 1 tothe cylinder of the pump 8 through the feed opening lOandany oil that rmay have been supplied to the pipe 11 passes therefrom into the cylinder of the; dispensing pump. ,9, Upon the forward stroke of the plungers 8 and 9 oil is discharged from the pump 8' and pipe l2'into the pipe ll'and from the pump 9- mm the distributing pipe 21,-it being assumed that the pipe 12 and cylinder of the pump-8- have been previously charged. The oil forced from the cylinder of the dispensing pump 9' container, the auxiliary pump-having an outlet externally of the container and avertically disposed inlet pipe within the container and open at its upper end, said primary pump: having inlet within the container and an outlet pipe extending upwardly fromits cylinder and terminating 'in a curved upper end ort'i'on disposed over the open upper end yoke extending transversely between andtsecured to said plungers and having its end portions provided with pintles, a rock shaft rota-tably carried by walls of'the container and extending above said plungers in crossed relation thereto with one end projecting outwardly from the container, depending arms ad-justably carried by said shaft and extending radially therefromand having slotted lower free end portions straddling the pi-n-tles of said yoke, and an actuating handle carried by, the outer end portion of said shaft.
