GREASE-CUP.

Application filed May 16. 1918.

To all whom it may concern:

Be it known that I, OLAF BAKKE, a citizen of the United States, residing at New England, in the county of I-Iettinger and State of North Dakota, have invented certain new and} useful Improvements in Grease-Cups, of which the following is'a specification- This invention relates to improvements in grease cups, and more particularly to that type adapted for feeding grease or other lubricants of a thick character and in which the cup is formed of two parts having threaded engagement with each other to provide for applying pressure to the lubricant to insure the feed thereof to the bearing to which the cup is connected.

In connecting grease cups of this character to bearings and especially to bearings of automobiles which are subjected to considerable vibration, the parts work loose and become lost or cease to exert pressure on the lubricant, and it is to overcome this objection that the device constituting this invention is devised.

Another ob ect is .to provide a grease cup which may be as easily adjusted as the ordinary cup and when adjusted, the'movable part may be easily locked in adjusted position by a simple locking device carried by the cup cap.

WVith the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the'precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings Figure 1 represents a side elevation of a grease cup constructed in accordance with v this invention with the cap shown in locked position thereon,

Fig. 2 is a similar view taken in a plane at rinht angles to Fig. 1 with the cap shown slightly unscrewed, and

Fig. 3 is a plan view showing the locking element in operative position.

In the embodiment illustrated, a grease cup 1 is shown provided at one end with the ordinary threaded stem 2 for connection with the bearing and is externally Specification of Letters Patent.

threaded on its upper enlarged end as shown at 3 to receive an internally threaded cup cap 4; whichis adapted to hold the lubricant and to be screwed downwardly ,on the body portion to force the lubricant out.

The cap 4- is provided on its cup with a pair of laterally spaced lugs 5 which incline downwardly in opposite directions gradually merging into the cap and preferably being formed integral therewith. By so constructing these lugs the locking element presently to be described may easily ride up on either one of them and be dropped between them in the sear. formed by their opposed ends. 7

This cap 4: is provided on one side wall with laterally extending vertically spaced and alined bearing ears 6 which are designed to receive an L-shaped locking member "his locking member 7 is composed of heavy spring wire and the terminal or free end of the arm which extends through the bearing 6 is bent at an oblique angle to form a finger 10 which when in operative position is designed to engage the face of the cup proper as shown clearly in Figs. 1 and 2. The short arm 8 of the member 7 is extended horizontally and adapted to swing over the upper face of the cup of cap 4, the lugs 5 on said cap being arranged in the path of said arm so that when the arm reaches the space or seat between these lugs it will drop thereinto and thus lock the cap to the cup as is shown clearly in Fig. 1. The free end of arm 8 has its terminal bent to form a loop 9 designed as a handle for operating the locking element.

In use, the cup is filled in the ordinary manner and the cap t is turned on the stem portion to exert the pressure on the lubricant. When the desired pressure has been obtained, the locking member 7 is turned in the bearing 6 by grasping the handle 9 which causes the arm 8 to swing over the top of cap 4 and to ride up on one of the in clined lugs 5 until it reaches the highest point thereof which is adjacent the space between the lugs and when said arm passes over this end, it will drop into the seat formed between the lugs and owing to its resiliency will closely hug the top of the cap and be held by the lugs against turning in either direction until it has been manually released from this position. When this arm is so locked the finger 10 will have gripping engagement with the inclined face of the body proper 1 as shown in Fig. 1, thus exerting a clamping action on the cap and holding it securely against turning onthe body portion of the cup. The foregoing description and the drawings have reference to hat may be considered the preferred or approved form of my invention. It is to be understood that I may make such changes in construction and arrangement and combination of parts, materials, dimensions, etc., as may prove expedient and fall Within the'scope of the claimed invention. p 7

Having thus fully described my invention, What I claim as new and desire to secureby Letters'Patent is j 1, A. grease cup comprising a fixed member, a 'r'otat able cap movable onthe fixed member, and rotatable means carried by said cap for engaging th fixed member to lock thecap against rotation. v x "2. A grease cup comprising a fixed menr her, a cap rotatable thereon, a rotatable rod carried by said cap, and means on said rod for clampingly connecting the cap to "the cup. r a

A grease cup comprising a fixed member, 'acap rotatable thereon, and having' laterally extending vertically spaced and ali'nedi bearings, an L-shaped locking member having'on'e arn mount'ed on said bearings with its free end extending below the bot tom of the cap and shaped to engage the cup of'said member in operative position.
