A. G. BUZBY.
LUBRIGATOR.
(No Model.)
N0. 434 ,059. Patented Aug. 12, 189 0.
- UNITED STATES PATENT OFFICE.
AUGUSTUS O. BUZBY, OF PHILADELPHIA, PENNSYLVANIA.
LUBRlICATOR.
SPECIFICATION forming part of Letters Patent No. 434,059, dated August 12, 1890.
Application filed December 5 1887.
To all whom it may concern:
Be it known that I, AUGUSTUS G. BUZBY, a citizen of the United States, and a resident of Philadelphia, Pennsylvania, have invented a new and useful Improvement in Lubricators, of which the following is a full, clear, and axact description, reference being had to the annexed drawings, making part hereof.
The nature of my invention will fully appear from the following specification and claims.
In the drawings, Figure 1 is a vertical sectional view of my lubricator. Fig. 2 shows a partial modification of my device, and is a detached broken elevation of one part of the stem, showing the enlargement therein, and openings to permit the passage of grease; Fig. 3, a plan view of mydevice; Fig. 4:, a broken sectional view of the top thereof on line X Y of Fig. 3.
The dotted lines in Fig. 1 illustrate the inverted cup when sunk to nearly its fullest extent to drive out the grease.
A is the upper part or section of a male screw-threaded stem; 13, a hollowed enlargement in the same having lateral openings or. slits C; D, a saucer-like flange on stem A, concave on its upper surface; E, the hollow lower part of the stem A, and is practically a continuation of the latter. It is screwthreaded to engage in a female screw-threaded hole in the bearing of a shaft or other part to be lubricated.
F is an inverted cup or reservoir, which I make either of metal or of glass; G, the internal passage-Way in part E of the stem,
opening above into hollowed enlargement 13,, and open below to permit the flow of the lubricant to the part to be lubricated. The top H of the cup, when the latter is made of glass, is pierced with a central square or other polygonally-shaped hole, into whichZfits a correspondingly-shaped metallic block I, having a lower flange J and an upper overlapping plate K, screwed fast to block I by means of small screws L. This flange J, plate K, and block I constitute a collar, between the lips of which the glass top H is held securely. The block I is pierced with a central screw-threaded hole, which permits it to engage with the screw-threaded stem A. This flanged block Serial No. 257,002. (No model.)
I and the rest of the upper shell of the glass cup form practically the top of the cup, the metallic block I being simply introduced to permit the formation of a female screwthreaded hole in the top to engage with the thread of stem A. In my claim I desire by the broad use of the word top to include either form, whether all of metal, or part metal and part glass. The stem A, parts B, D, and E are shown as all cast in one piece. They are turned up or finished on a lathe. The square opening in top H permits the latter to engage with the square block I and to turn the latter, either to release cup' F from stem A or to screw it down upon the latter. The
outer edge of flange D may be provided with.
an annular groove, and a packing-ring may be inserted therein; but this is an .old device and I have not shown it.
The operation of my lubricator is as follows: The cup F is unscrewed and removed from stem A, and is then filled with grease or other thick lubricant. It is then screwed back into place on the stem A, and the grease is forced down in any quantity desired by gradually depressing the cup, which is done by turning it. The grease as it is compressed is forced through opening 0 and passage G to the point to be lubricated. It is evident that the most infinitesimal quantity of grease can be forced out by giving a very slight turn to the cup, or as large aquantity as desired may be ejected by giving a complete or several complete turns thereto. When the cup is forced slightly below the position shown in dotted lines, the grease will be so nearly exhausted as to require renewal, which can be done after removing the cup, as described above. The concave form of the upper surface of the saucer-shaped flange D gives a direction to the movement of the grease being expelled and obviates its tendency to ooze out at the joint between the inside of cup Fand the outer edge of flange D. Though this joint is snug and close, this concave form is important for the reasons stated.
I am aware that spring-compressors have been used heretofore to force down a disk to eject the grease, and it has been done by means of the weight of the cup; also that pins and toothed racks have been used; .but
I do not claim any of these, for by their use the feed of grease cannot be accurately and definitely controlled.
What I claim as new is- 1. In a grease-cup, the stem A E, pierced with opening C, the lower part E being hollow, (provided with concave flange D,) in
combination with the inverted cup F, the middleof the top of which is composed of the screw-threaded double-flanged collar I J K', substantially as described.
2. In a grease-cup, the stem A E, pierced with opening 0, (the lower part E being hollow,)'provided with a concave flange D, in combination with an inverted cup F, engaging centrally at its top with the section 'A of the stem by a female screw-threaded hole, the said flange engaging around its outer edge with the interior surface of the cup, substantially as described.
