AUTOMATIC GREASE-CUP.

Specification of Letters Patent.

Patented J an. 23, 1912.

Application filed October 1, 1909. Serial No. 520,494.

To all whom it may concern:

Be it known that. I, Jonx F. LEWIS, a citizen of the United States. residing at Philadelphia. in the county of Philadelphia 5 and State of Pennsylvania. have invented a certain new and useful Improvement, in Automatic Grease-Cups, of which the follow ing is a specification.

My invention relates to a new and useful improvement in automatic grease cups, and has for its object to provide such a cup in which the grease will befed by means of compressed aircontained in the upper portion of the cup, and yet when desired positively forced therefrom without cutting off the air p1-essui'e,'and in which the cup will always empty itself.

With these ends in View, this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.

In order that those skilled in the art to which thisinvention appertains may understand how to make and use the same the construction and operation will now be described in detail referring to the accompanying drawings, forming a part of this specification, in which- Figure 1 is a plan view of my improved cup, a portion thereof being broken away to show the cap and cap tube therein. Fig. 2' a vertical section. Fig. 3 a plan View of the funnel. Fig. i a section of the funnel, at

of the removable cap and the tube carried thereby.

My improved grease cup consists of the body portion A. and the top portion B. The bodyportion being provided with internal threads C, while the top portion is provided with corresponding external threads D, in order that they may be screwed together plainly shown in Fig i. A jam nut-w is also run .upon the threads I) and is adapted to be forced into contact with the upper edge of the body so as to hold the portion B in any adjustment may be readily understood.

The lower portion of the body A is enlarged or swelled out as indicated at F to form a multiple sided Wrench hold and also to produce an enlarged chamber. A threaded nipple G is formed with the bottom of the body for screwing into the bearing to I be lubricated.

the line of Fig. 2 and Fig. 5 a plan view .11 represents a cap preferablymade of sheet metal, stamped into saucer shape hav' ingaflange which snugly fits within the top portion 15 and the tube 1 is secured in this cap and projects above the same to form a stop to determine the position of the cap in the portion B by coming in, contact with the top thereof, passes to the space above the cap when being compressed and flows back when being expanded.

J is a disk adapted to scrape the walls 01 the upper portion B in moving up and down therein and to this disk is secured the staple shaped wire K the latter adapted to slide into the tube and being prevented from accidental withdrawal therefrom by the pin L, thus permitting the disk to rest uponthe grease contained in the cup and maintain an even surface.

M represents extends through the nipple its end being spun over, and the sides of this funnel and spout are corrugated or fluted as clearly shown i Fig. 4 so as to leave passages from the lower portion of the cup to the nipple, and holes 0 are formed in the spout of the tunnel for the purpose hereinafter set forth: In practice after the body has been filled with grease the top portion is screwed therein, the disk coming in contact with the grease will be forcedupward into the top portion compressing the air until the disk is stopped by the cap H, the space above the cap acting as a reservoir for the compressed air. Any further downward movement of the top Bwill force the grease through the tunnel to the bearing with screw pressure, but when the top 13 is stopped in any position the air compressed in the upper portionthereof will exert suflicient pressure on ll'lrough this tube the air a funnel the spout bf which 1 the disk and grease to continue to feed the latter. edges of the disk come in contact with the flange of the cap H the center portion of the disk also comes'in contact with the tube I thus supporting the disk against undue pressure. When a sufiicient amount of the grease has been fed from the cup'to bring It is to be noted that when the the disk J into contact with the funnel the H and the disk+J the grease will not be forced intothe cap nor above it, thus leaving suflicient space to act; as an air-reservolr. The. ends of the wire K project belowthe disk and maybe utilized to draw the disk downward should it become stuck in the top;

Of course I'do notwish to be limited to I the exact details of construction here shown as these may be varied within the limit of the claims without departing from the spirit of my invention.

Having thus fully described my inVcntion, What .I claim as new and useful, is

1Q A grease cup consisting of'a body and an upper portion the latter threaded into the former, a removable cap set in .the upper portion, a tube carried by said 'cap adapted to serve as astop, a disk, a guide wire secured to said i into said tube, means for preventing accidental withdrawal of the; guide wire, and

a funnel, the spout of which projects into the outlet from the body portion of the cup as specified.

disk and projecting.

2. In combination with a grease cup of] the character described, a saucer shaped cap adapted to be forced into the upper portion of the cup, a tube carried by the cap for determining the position of the latter,

a disk, a, staple-shaped wire carried by the disk adapted to extend into the tube, a funnel, thesides and spout of which are cor-.

rugated said spout projecting into the outlet from vthe body portion of the cup, as and for the purpose set forth.

3. In combination with a greasecup of the character described, a funnel, the spoutof which projects'into the outlet of the cup and is secured therein so as to form a space outside of the funnel and its spout, the lower end of. said space being closed, said spout having a hole in its side near its -lower end, the funnel and spout being corrugated to permit the passage of grease around the outside thereof, as and for the purpose set forth. In testimony whereof, I have hereunto aflixed my signature in the presence of two subscribing witnessesl JOHN F. LEWIS.
