lMPROV-EMENT IN BEARINGS FOR SHAFTI NG.
Specification forming part of Letters Patent No. 177,053, dated May 2, 1876; application filed May 19,1875.
To all whom it may concern Be it known that I, MOSES H. BOYDEN, of
'Ohicopee Falls, in the State ofMassachusetts,
. ing, and to conduct the oil, after being once used, back to the oil-reservoir, so that it may be used over again, and that continuously, so long as the oil lasts. To this end my invention consists of a box or bearing resting on flanges in an oil-reservoir, and provided with a shallow oil-receptacle along its bottom, and with ducts, through which the oil is drawn from the reservoir up into said receptacle by the friction of the shaft turning in its bearin g, and provided also with beveled flanges and recesses, their edges to conduct the oil back to the reservoir after having been used, where, being freed from its sediment, it is ready to be used again.
Theoil-reservoir is provided with trunnions, which rest in a swinging yoke, so that the box may be readily adjusted to the variations in the line of shafting by set-screws turned in or out through the hanger against the trunnions or against the stem of the swinging yoke, or against the top of the box itself.
In order that the invention may be fully understood, I will proceed to describe it, having reference to the accompanying drawings, and to the letters of reference marked thereon.
Figure 1 is an end view of the box suspended Fig. 2 is a half-plan view of the box and half plan of the oil-reservoir. Fig. 3 is a longitudinal section at line 0. Fig. 4 is a transverse vertical section at line L, and Fig. 5 is a half longitudinal section of the box-cover at the center line.
0 represents a hanger, in the lower part of which is made a vertical hole to receive the stem I of a yoke, 0, so that said yoke may turn freely therein, its lower end resting upon This oil-reservoir is made with a deinterior shoulder, 0, extending along itslength on each side, and with recessese at suitable distances'apart, the use of which will be ex plained hereafter. Within this oil-reservoir.
B is the box or journal G, provided with a flange, 0, on each side, which flanges have a' firm bearing upon the interior shoulders c, to support the'box in place; and these flanges are recessed at e, at suitable distances apart, and are slightly beveled on top, as
shown clearly in Fig. 4. The box G is also provided with protuberances d, which extend down to the bottom of the oil-reservoir at points a little distant each way from the deep est part of the reservoir, through which are made holes or ducts d, asshown clearly in Fig. 3; and the reservoir is provided near each end, and. outside each end of the box, with cut-offs f, the inner ends of which extend into the plane of the interior of the box, as shown in Fig. 5.
Two set-screws, E and E are turned in through thehanger against the ends of the trunnions D of the oil-reservoir, and one, E is turned down through the hanger against the top of the cover a of the reservoir. The cover a of the reservoir is provided with cutoffs 00, having a spring, :10, between the lower enlarged end and the interior surface of the box-cover, to keep the lower end of the cut-offs always in contact with the shaft.
The operation of my invention is as follows: The oil-reservoir, with the box or journal G arrai'iged therein, is placed with its trunnions in the recesses in the yoke G, and the shafting being placed therein, the cover a'is put in place, and the whole properly adjusted to the line of shafting by turning the set-screws E, E E and E either in or out, so that the inner end of the screws may impinge against the trunnions and cover, the inner end of the screw E impinging against the lower end of the stem I of the yoke.
After the bearing is properly adjusted, oil s poured into the reservoir through the hole filling the reservoir until the oil appears in ;he filling-pan F, made on the outside-of thereservoir.
As the shafting is put in motion the friction 1 )f the shaft in the journal G draws the oil up :rom the reservoir through the duct-tubes d, tnd thoroughly lubricates the shaft at its whole bearing, keeping a small quantity of oil zonstantl y in the shallow recess or receptacle t. in the bottom of the box G, in close contact, with the shaft along the entire length of the box. The outer ends of the cut-offs f rub against the shaft as it revolves, and prevent She oil from collecting upon the shaft beyond them, and the oil is forced back into the reservoir. The oil also collects upon the flanges c, :which are beveled back to the edges of the reservoir,) and the oil runs down through the recesses c and a into the reservoir again. All
the sediment which may have collected in the oil by use settles into the deepest part a of the reservoir and when the oil is again, drawn up through the duettubes (1 upon the shaft it is clean and comparatively pure.
It willthus be seen that the oil in the reservoir may he used over and over again without material diminution, and the shaft be lubricated along time, and the journal be so adjusted that the shaft will have an equal hearing throughout the box, and receive lubrication at all its bearing-points.
To prevent dust and dirt'from entering the hearing, I deem it best to make an annular flange, g, of nearly the same internal diameteras the bearing surface of the box G, by which the shaft is nearly inclosed.
As fast as the shaft becomes worn away the inner ends of the cutoffs m are forced in against the shaft by the springm, which causes said cut-offs to follow up the wear of the shaft I and'keep them in constant contact with it.
Having thus described my inventio nlwhat I; claim as new is- The combination of the swinging yoke U,
scribed.
