To a/ZZ whom t may concern.-

Be it known that I, LEE B. MANES, a citizen of the United States, residing at Elsinore, in the county of Riverside and State of California, have invented new and useful Improvements in Lubricators, of which the following is a specification.

My invention relates to lubricators; and its primary object is to provide a novel form of lubricator which is adapted to feed lubricant to the bearings of a line-shaft and be automatically operated and controlled by and during the rotation of the line-shaft.

A further object of the invention is to provide means for reconveying an oversupply of lubricant from the drip-nozzle back to the reservoir, thereby preventing waste of lubricant.

Still further objects of the invention will appear as the nature of the same is more fully understood from the accompanying description and accompanying drawings.

The invention consists in the construction, combination, and arrangement of parts hereinafter fully described, claimed, and illustrated in the accompanying drawings, in which- Eigure 1 is an elevation of a lubricator constructed in accordance with my invention and shown in applied position, the pumpcylinder being in longitudinal section. Fig. 2 is a detail side elevation of the striker-arm, showing the manner in which it is applied to the line-shaft.

Referring to the drawings by referencenumerals, 1 indicates a hanger provided with the usual bearing 2, in which is journaled and supported a ine-shaft 3. 4 indicatesa pump-cylinder fully opened at its upper and lower ends and provided with externally-arranged screw-threads adjacent its ends. The lower end of the cylinder has removably secured thereto a bottom 5, provided with a depending internally-threaded nipple 6, havingcommunication with the interior of the cylinder, the inner surface of said bottom being inclined downward toward its center to adapt it to form a seat for a valve 7, convexed in cross-section. The valve 7 is provided with a centrally-located depending lug 8, adapted to normally fit within the nipple 6 and guide the valve during its movement,

whereby all liability of the valve becoming disengaged and not properly seating itself is obviated.

The cylinder has connection with a reservoir 9 of any preferred construction by means of a feed-pipe 10, the latter having one of its ends connected to the bottom of the reservoir `and its other end connected to the threaded portion of the nipple 6. The upper end of the cylinder is normally closed by a removable cap 1 1, which is provided with a centrally-located aperture 12. Arranged adjacent to the upper end of the cylinder and on the interior thereof is a packing-box 13, formed by relatively arranging in the cylinder reversely positioned concavo convex plates 14, which are provided with oppositely-disposed collars 15, centrally arranged and adapted to provide bearings for the reception of a reciprocating piston-rod 16. Secured to the lower end of said piston-rod is a hollow piston-head 1 7, which is provided with a concaved valve-seat 18, adapted to receive a valve 19, similar in construction to the This valve isalso provided with a lug 20, which operates to guide said valve in its movement. Positioned between the packing-box and the upper portion of the piston-head 17, is an expansion-spring 21, which acts to normally retain said pistonhead in the lower portion of the cylinder or at a point at the extremity of its downward stroke, said downward movement of the piston-head being limited by an annular stop 22, secured upon the interior of the cylinder at a point adjacent its lower end. An arm 23 is secured to the cylinder and has its upper extremity projected above the upper end of the cylinder, said extremity being adapted to have pivotally secured thereto an operating-lever 24 to position the free end of said lever in the path of the movement of a strikerarm 25. The lever 24 is secured to the piston-rod 16 by means of a link connection 26. The cylinder is provided with a dischargeopening 27, situated at a point adjacent the packing-box 18, and secured to the cylinder and communicating with said dischargeopening is a feed-pipe 28, having its opposite end connected by means of a union 29 to a drip-nozzle 30. Connected to the upper end l of said union is a return-pipe 31, having its IOO lower end positioned above a funnel 32', secured to the top of the reservoir 9, whereby when an excessive supply of oil is 'conveyed to the drip-nozzle 30 it will be readily reconveyed back to the reservoir 9 through said pipe 31.

The structure above described is adapted to be secured in its entirety in such position that the discharge end of the drip-nozzle 30 will be positioned above the bearing 2 and the lever will be positioned above and in parallel alinement with the shaft 3, and in order to accomplish this l utilize two bracket-arms, one (indicated by 32) being secured to the hanger l and the cylinder 4 and the other (indicated by 33) being secured to any horizontal support and said cylinder. The striker-arm 25 has one of its ends curved in the arc of a circle, as indicated by the numeral 34, and its other end is securedto the shaft 3 by means of a coupling 34a, said striker-arm being positioned upon the shaft 3 in such a manner thatits curved end 34 will engage the free end of the operatinglever 24 during the rotation of the shaft.

The operation of the device may be described in the following manner: It is apparent that during the rotation of the shaft 3 the curved end of the striker-arm 25 will successively engage the free end of the operating-lever 24 and through virtue of its engagement cause said lever to be swung upwardly upon its pivot. This upward movement of the lever 25 will cause the pistonhead 17 to correspondingly move upward in the cylinder against the tension of the spring 2l, thereby drawing a quantity of lubricant from the reservoir through the pipe 10 into the bottom of the cylinder. As the shaft revolves sufliciently to move the striker-arm out of engagement with the lever 24, the piston-head will be free to be moved downward by the spring 21, thereby unseating the valve 19 and permitting the lubricant which was drawn within the cylinder by the upward movement of the piston-head to flow above said piston-head. When the strikerarm again operates the lever 24, the lubricant above the piston-head will be forced through the pipe 28 to the feed-nozzle 30, from whence it may be fed to the bearing 2 in any desired quantity, the quantity of the feed being regulated by a valve 34h, positioned in the drip-nozzle. When a greater quantity of lubricant is fed to the drip-nozzie 30 than is necessary, said excess of lubricant will be returned to the reservoir 9 through the pipe 31, and to control and regulate said return I provide a valve 35, which is positioned in said pipe 31.

lt is apparent from the above description, in connection with the accompanying drawtween said lever Yand piston-rod, a drip-noz- Zle having connection with said cylinder, and a striker-arm secured to said shaft and adapted to engage the lever to move the pistonhead upward within the cylinder.
