UNITED STATES PATENT OFFICE.
sAMUEL M. MAIN, E BROOKLYN, NEW YORK, ASSIGNOR OF ONE-HALF TO SAMUEL A. MAIN, OF DANBURY, CONNECTICUT.
LUBRICATOR.
SPECIFICATION forming part of Letters Patent No. 336,578, dated February 23, 1886.
Application filed October 8, 1885. Serial No.179,323. (Modem To aZl whom it may concern:
Be it known that I, SAMUEL M. MAIN, of the city of Brooklyn, in the county of Kings and State of New York, have invented acertain new and. useful Improvement in Lubrieators; and I do declare the following to be a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanyingdrawings, showing views thereof, and forming part of said specification, wherein like letters of reference indicate corresponding parts.
Figure 1 is a vertical section of the lubri- [5 cator, and Fig. 2 a side View of my method of fixing the cap.
The improvement relates to that class of lubrieators which depend for their action up on a device for transmitting frictional heat go from the journal to a lubricant which can be melted and the melted lubricant returned to the journal, the lubricant being of such a nature thatit remains set at ordinary temperature, and liquefies only when heated by the journal beginning to run hot.
The improvement consists in atwisted strip of some good heat-conducting metal-such as copper-inclosed in a tube, connecting the cup holding the lubricant with thejournal, and of sufficient length to be in contact with said journal. and to extend upward into the body of the lubricant in said cup, and also in connection with a heat-transmitting spiral of a size and shape proportioned to the cup and 5 within the body'of the lubricant therein, for the purpose of diffusing the transmitted heat throughout said body; also, in an adjustable stop to prevent any churning of the twisted strip when applied, for instance, to a crank 0 running at high speed; also, in spring-catches for holding on the cap and making it easily removable.
In Fig. 1 of the drawings A is an ordinary grease-cup; B, its tubular stem, of any de- 5 sired size, connecting it with the shaft 0 through the usual opening in the cap-plate of the journal-box, and secured therein in any of the ways well known to mechanics.
D is a strip of some good heat-conducting metal twisted a number of times, so that its full width shall bear upon and be in contact with the shaft, and its convolutions extend upward through the tube B into the cup A.
E is a heat-conducting metal spiral for the purpose specified, and in this instance of an 55,
invertedcone shape. Instead, a perforated funnel-shell of the same heat-conducting metal may be used with the same result.
The lid F of the cup may be secured in any convenient way. I prefer the way shown in Fig. 2. The pin H enters the slot I, and in passing along the longitudinal portion of the slot as the cap is turned is caught and held by a suitable notch in the spring-catch K,affixed to the outside of the rim of the cap,as shown. 6 The tongue forming the slot when of suitable metal and temper may be similarly constructed for the same purpose. I place similar catches on opposite sides of the cap.
The twisting of the heat-conducting strip permits, practically, a solid column of the lubricant to rest upon the shaft, while its con volutions form continuous downward inclines, assisting the how of the lubricant and preventing clogging. A rod instead would itself 7 fill the tube. I prefer to make the upper portion of D like a rod,to allow it to pass through the lid of the cup and to take upon it a common nut, G, below the lid, and so adjusted in relation thereto as to prevent a churning motion of the rod when applied, for instance, to the crank of a locomotive, which runs at ahigh rate of speed.
\Vhat I claim as new, and desire to secure by Letters Patent, is-
1. The heattransmitting twisted strip, its
width at the lower end bearing upon and in constant contact with a shaft or journal, and
its upper end communicating to the lubricant, substantially as described, for the purpose o specified.
2. The heat-transmitting twisted strip specifled, in combination with a heat-transmitting metal coil or spiral or shell within the body of the lubricant, substantially as described, for the purpose specified.
3. The rod extending through the cap, and the nut below the cap or lid adjustable, substantially as described, for the purpose specified.
4. The heat-transmitting twisted strip D slot I and pin H, substantially as described, and adjustable stop G, in a tube, B, together for the purpose specified. with the heat-diffusing coil E and grease-cup Dated New York, October 6,1885. A, in connection with a shaft or journal, sub- 5 stantially as described, for the purpose speci- \Vitnesses:
