I /IIJ'I UNITED STATES PATENT OFFICE.

HERMAN D. KUHLMAN. OF OMAHA, NEBRASKA.

LUBRICATOR.

Application led August 2, 1919.

To all whom t may concern.'

it known that I. HERMAN D. Ianni.- girfxn, a citizen of the United States, residing at Omaha 'in the count i of DouO'las and.

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

rThis invention relates to certain improvements in lubricators and has relation more particularly to a device of this general character eml'iodying a force. feed including a merhanically operated follower, and it is an object of the invention to provide a. novel and improved device of this general character including a cup provided with a iilling opening and wherein a closing member coact-s with the opening and is adjusted or moved into open position by the follower during its retracted movement.

It is alsoan object of the invention to provide a novel and improved device of this general character including a follower mounted for movement within a cup and wherein means is provided for effectively holding the follower against movement.

The invent-ion consists in the details of construction and in the combination and arrangement of the several parts of my improved lubricator whereby certain important ad f'antages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will Aiereinafter be definitely claimed.

In order that my invention may be the better understood7 I will now proceed to describe the saine with reference to the accompanying drawings, wherein:

Figure l is a view partly in section and partly in elevation illustrating a lubricator constructed in accordance with an embodiment of my invention.

Fig. 2 is a view partly in section and partly in top plan of the device illustrated in Fig. 1.

Fig. 3 is a sectional view taken substantially on the line 3-3 of Fig. l.

As disclosed in the accompanying drawings, C denotes a cup of requisite dimensions and provided in its bottom with a central discharge or reduction opening f l Specification cf Letters Patent.

Serial No. 314,877.

through which grease or other lubricant is adapted to be forced. The interior walls of the cup C are smooth and unobstructed and the upper or outer end portion of the cup C is closed by a cap 2. Threaded through the central portion of the cap 2 is a rod 3 having affixed to the inner end portion a follower or piston el so that upon rot-ation of the rod 3 in one direction the follower or piston will be caused to move inwardly or downwardly to eil'ect the desired ejection of the lubricant within the cup.

A side wall of the cap 2 is provided with an opening 5 normally closed by the slide 6 having movement in a direction longitudinally of the cup C. The slide 6 is provided with an inwardly directed lug with which the follower or piston 4 contacts when said follower or piston is retraeted so that the u pward or outward movement of the follower or piston et serves to move the slide 6 into open position so that grease or other lubricant may be applied within the cup C inwardly of the follower or piston d. After the lubricant has `been applied within the cup C the slide 6 is returned manually to its normal and closed position.

The rod 3 is threaded substantially its entire length and engaged therewith is a jam or locking nut 8 provided with an outstanding lever 9 whereby the requisite ro tation may be imparted to the nut S as the occasions of practice may require. l

After the slide 6 has been returned to its closed or normal position the lever 9 is swung into a position to overlie the outer or upper edge of the slide to hold the same in closed position and said movement of the lever 9 also causes the nut 8 to tighten against the cap 2 to hold the rod 3 in position.

The outer end portion of the rod 3 is provided with a handle l0 or other means whereby the requisite rotation may be imparted thereto to cause the follower or pistou et to move in the desired direction longitudinally of the cup C. Vhen it is desired to move the follower or piston l upwardly or outwardly and to elevate or raise the slide 6, the lever 9 is swung sufficiently to free the slide 6 and in order to limit the extent of this lateral swinging movement of the lever 9 the cap 2 is provided with an outstanding stop lug ll with which said lever 9 contacts. The stop lug 11 also serves to hold the nut S and lever 9 from rotating when the rod 3 1s being rotated 111 a direction to move the follower or piston 4 upwardly or out.

wardly. l

My improved lubricator as herein disclosed is primarily adapted for use in connection with locomotive crank pins, lout I do not wish to loe understood as limiting myself to this particular usage. It is also to be understood that the follower or piston el fits snugly within the cup C.

From the foregoing description, it is thought to he obvious that a lubricator constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated and it will also be obvious that my invention is s-usceptible of some change and modification without departing from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.

I claim: v

1. A lubricator comprising a cup pro vided with a filling opening in a side wall, a slide for closing said opening, a follower arranged Within the cup, means for moving the follower in opposite directions longitudinally of the cup, said slide being provided lwith means whereby the follower upon movement in one direction, moves the slide 1nto open position.

2. A lubricator comprismg a cup provided with a filling opening in a side wall, a slide for closing said opening, a follower arranged within the cup, means for moving the follower in opposite directions longitudinally of the cup, and an inwardly directed lug carried by the slide engaged 'by the follower upon movement in one direction for moving the slide into open position.

3. A luhricator comprising a cup having a filling opening in a wall thereof, a slide for closing said opening, a follower within the cup, a rod extending eXteriorly of the cup for imparting movement to the follower in either direction longitudinally of the cup, and means carried by the rod for holding the slide in closed position. Y

4. A lubricator comprising a cup having a filling opening in a wall thereof, a slide for closing said opening, a follower within the cup, a rod extending eXteri-orly of the cup for imparting movement to the follower in either direction longitudinally of the cup, anut threaded upon Vthe rod exteriorly of the cup and provided with an outstanding lever, said lever in one position coacting with the slide for holding the same in closed position.

In testimony whereof I hereunto aiiX my signature.

HERMAN D. KUHLMAN.
