To all whom it may; concern Be it known that l, Wrrnrasr F. Danna, citizen of the 'United States, residing at Jacksonville,in the county Randolph State of Missouri, have invented and useful improvements in Cap-Locking Devices for Grease ilups, of which the felt lowing is a specification. l I This invention relates to improvements in grease cup devices for applying hard lubrieating compounds to. the moving parts of machinery, and has for one of its objects to provide a simply constructed device whereby the lubricant may be forced upon the journal asfast as required and the moving parts locked in position to prevent displacement under jars and concussions incident to devices of this character.
Another object of the invention is to provide a simply constructed device which may be applied to the various forms of lubricating, devices without material structural change.
With these and other objects in view, the invention consists in certain'novel. features of construction as hereinafter shown and described, andthen specifically pointed out in the claims; andin the drawings illustrative of the preferred embodimentof the invention,
Figure 1 is a vertical sectional elevation of the improved device applied; Fig. 2 is a side elevation of the same; F ig. 3 is a transverse section on the line 3-3 of Fig. 1; Fig. 4 is a plan view in section on the line e'i of Fig. 1; Fig. 5 is a detached perspective View of the catch holding member; Fig. 6 is a view similar to Fig. 1, illustrating a modification in the construction; Fig. 7 is a detached perspective view of the resilient locking member employed in the. structure shown in Fig. 6; Fig. 8 is a detached perspective view of the releasing device employed in the structure shown in Fig. 6; Fig. 9 is a detached perspective view of the supporting bracket employed in the structure shown in v F ig. 6; Fig. 10 is a. perspective 1 View of a modified form of, resilient locking member; Fig. 11 is a perspective view of a modified form of the releasing member employed in'co'nnectic-n with the modified locking'member shown in Fig. 12.
Corresponding and like parts are referred to in the following description. and indicated Patented Dec. is, 191255. no. tears.
' in all the views ofthe accompanying drawings by the same reference characters.
The improved device includes a hollow stem or body, represented as a whole at 10, and including an externally threaded lower portion 11 and enlarged into a receptacle for portion or the lubricant at the upper end, as r presented at 12. A portion of the stem between the receptacle l2 and the threaded portion 11 is formed with a plurality of wrench engaging fiat faces, as shown in Figs. 2 and 10. The threaded portion 11 is designed to engage in a journal box or ike device, a portion of which is represented at 13, and a portion of the shaft withthe journal box is represented at 14. The journal box- 13 is provided with an cri- 15 for the lubricant and communicating with the discharge orifice 16 in the stem 10. By this means the lubricant from the receptacle 12 is free to pass through the 'alined'orifices to the shaft 14 in the usual manner.
The outer face of the receptacle portion 12 is externally threaded to receive a cap device 17 internally threaded and thereby adjustable relative to the receptacle portion 12-. The cap 18 is relatively large and closed at the outer end and is designed to contain the remaining portion of the lubricant. At its lower edge, the cap 17 isprovided with a plurality of teeth 18 preferably rounded, as shown, the object to be hereinafter explained.
In operating the device, the receptacle portion is first filled with the lubricant, and the cap 17 inverted and likewise supplied with the remaining portion of the lubricant and then engaged by its threads with the upper threaded portion 12 of the member 10. Then, as the cap is screwed downwardly, the lubricant is forced through the orifices to the journal. As before stated, the lubricating material is of the hard variety, such as tallow and the like, and will be supplied to the journal only when forced through the orifices which is done by actucap 1''? aiid it to rotate and compregs an. abnormal quantity of the lubricant through. the orifices, or rotatesin the opposite direction and fails to supply a sufficient quantity of the, lubricant. To overcome this objection, .means are provided in the 1mproved device for looking the cap 17 in its adjusted position, so that after being rotated to a sufiicient extent tosupply the requisite amount of lubricant to the bearing, the cap is locked in position and further movement prevented.
The improved locking device includes a holding member, represented in Fig. 5 conclamped in position.
A bolt 23 extends through the terminals 2021 externally of the rivets 22, and mounted for rotation upon this bolt 23 is a holding device comprising a bar 24 having a spring engaging extension 25. At its upper end the bar 24 engages with the teeth 18 one at a time, and thus locks the cap 17 in position relative to the stem, while at the same time the bar may be readily released from the teeth when the cap is to be actu ated to force the lubricant through the orifices. A spring or like device 26 isemployed to hold the member 24 either in engagement with the teeth or free therefrom,
' and is preferably coupled to. the rivets 22 between the terminals 20-21 of the band 19. The spring is provided with a depres sion to receive the extension 25 of the member 24, as shown in Fig. 1, but will yield to pressure suflicient to move the member 24 outwardly to free the same from engagement with the teeth 18, and will then exert its force to hold the member 24 in disconnected position and free the cap 19 when a fresh supply of lubricant is to be placed in the device, or to hold the cap unlocked when it is being manipulated to supply the lubricant to the device. Then, after the cap 17 has been actuated to the required extent, an upward movement of the member 24 will restore it to its position in engagement with the adjacent tooth, while at the same time the spring 26 will again engage with the extension 25 and hold the bar in position.
In, Fig. (3 a slight modification is shown in the construction of the locking device including a bracket 27 having ears 28 spaced apart and connected in any suitable manner to the portion 12 of the stem. A pivot bolt or like device 29 passes through the ears. In the modified structure shown in Fig. 6 the member 24 is continued downwardly and riveted or otherwise secured to the portion 12 of the stem, and is thus held normally in yieldable engagement with one of the teeth 18.
Mounted to swing upon the pivot 28 be.
tween the cars 28 is a combined releasing and locking device including an upper reduced portion 30 and a lower cam like portion 31, the upper portion 30 being bent outwardly and passing through a slot 32 in the member 24, while the cam like portion bears normally against the inner face of the member 24, as shown. When the parts are arranged as shown in Fig. 6, the releasing member exerts no influence, but when the member 24 is to be released, an outwardly and downwardly exerted pressure upon the portion 30 will cause the cam like portion 31 to move the member 24 outwardly and release it from the teeth 18, and hold it thus free until the portion 30 is moved upwardly again.
In Figs 10 and 11 the member 24 is shown without the slot 32 and the member 30 provided with a slot 33 to receive the member 24.
This arrangement of the parts may be employed, if preferred, but would not be a departure from the principle of the invention, or sacrificing any of its advantages.
Having thus described the invention, What is claimed as new is 1. A grease cup including a base portion having a receptacle for a portion of the lubricant and a discharge orifice, said base portion adapted to be coupled to a bearing, a cap movably engaging said base portion and having a plurality of laterally directed teeth, a resilient arm connected to said base and yieldably engaging said teeth, one at-a time, and a releasing device adapted to engage said resilient arm and move the same out of the path of the teeth and hold it in released posi ion.
