JOHN S. WHITNEY, OF LOWELL, MASSACHUSETTS.

LUBRICATING APPARATUS FOR BEARINGS IN MACHINERY.

SPECIFICATION forming part of Letters Patent No. 244,013, dated July 5, 1881.

Application filed April 6, 1881. (No model.)

To all whom 'it may concern Be it known that I, JoHN S. WHITNEY, of Lowell, in the county of Middlesex and State of Massachusetts, have invented a new Improvement in Lubricating Apparatus for Heavy J ournal-Bearin gs in Fast-RunningMachinery, of which the following is. a specification.

The object of this invention is toprovide an automatic oiler for heavy. fast-running bearings, whereby all waste of oil and the entrance of dust and dirt upon the bearings are prevented.

Figurel is a front elevation of the device in position on a-journal-bearin g. Fig. 2is a partlysectional plan of the same on line w m, Fig. 1. Fig. 3 is an enlarged sectional elevation on line y y, Fig. i. Fig. 4 is a cross-section on line zz, Fig. 5 is an enlargedsectional elevation of the supporting and guiding'mechanism of the pump cord or belt on line to to, Fig. 6. Fig. 6 is an enlarged sectional elevation of the same on line '12 c, Fig. 5. Fig. 7 is a cross-section of the same on line u to, Fig. 6.

Similar letters of reference indicate corresponding parts.

In the drawings, A represents a shaft, having a bearing in a journal-box, B, that is suspended in a hanger, O; and D represents a drippan, suspended bychains a a from the-box B, and having a well, 1), formed in one end.

In the eye of a suitable hanger, E, that depends from the beam 0, to which the hanger O is fastened, the pump-barrel F is fixed in a vertical position, with its lower end in the well I) of the drip-pan D, and its bent delivery pipe or spout F, which is provided with a cock, 0,

extended over the oil-opening d in the journal-box B. Said pump-barrel F is closed at the bottom with the exception of lateral openin gs ff, through which oil is admitted, andhas secured about its lower end over these openings f f a filter, G, of wiregauze or other suitable material, to prevent the ingress of any dirt that may be in the oil. 7

In the bottom of the pump-barrel F is a hearing or step, 9, for the end of the pump shaft or rod H.

Above the delivery pipe or spout F, on the opposite side of the pump-barrel F, an opening, 9, is made, whereby any excess of oil that maybe raised by the shaft or rod H may escape to flow back into the drip-pan D; and in the up per end of the pump-barrel F, above the eye of the hanger E, is an opening, 9 for the escape and return to the pan D of any oil in excess of that required for lubricating the upper part of the rod H, which may be brought up to that point by said rod H. This shaft or rod H has a right-hand screw, h, on its lower end for elevating the oil from the drip-pan D, and in its shoulder or bearing H is formed a righthand screw-thread, h, that extends upward to about the center of the opening 9 when said rod H is in position and a left-hand screwthread, 702, is cut in said bearing H, extending from the top of said rod H down to the upper terminus of the screw-thread h, whereby oil that is raised by the screw-thread h for lubricating the bearing H is prevented from ascending to the top of the pump, the thread h forcingjt out of the-opening 9 so that'it may run down the pump into the pan D.

On the top of the rod or shaft His a sheave, H by means of which said rod H is revolved.

In the eye of the hanger E is a horizontal slot, z, in which are secured two horizontal arms, I, that are pivoted one above the other, so as to move in a horizontal plane on the pump-barrel F, thatv passes down through their eyes i. The outer ends of these arms I are vertically slotted, as shown at These arms I are designed for the support of the devices K that support and guide the driving belt or cord P of the pump-barrel F. v

A belt supporting and guiding device, K, consists of a tube, K, having a parallel oilreservoir, K rigidly. attached to a side of it and extending the whole length thereof, both tube K and reservoir K being closed at the bottom and open at the top. At their upper ends the tube K and oil-reservoir K communicate with each other through an opening, k, and at their lower ends through an opening, k. These supporting devices K are provided with arms K rigidly secured upon them at right angles thereto, near their tops, by means of which arms K they are secured to the arms I. Screw-hooks L being passed up through the slots 6 of the arms I grasp the arms K and nuts L turned on said hooks L hold the devices K immovable.

Entered into the tubes K and having their lower ends journaled in the steps min the bottom of said tubes, K, are the rods or shafts M, on whose 'tops, that reach above the said tubes K, are rigidly fixed the guiding-sheaves N. The lower ends of these rods or shafts M have left-hand screw-threadsn formedin them, and their upper ends have right-hand screwthreads, n,- hence as the said rods M are revolved to the left hand oil will be drawn continuously from the reservoir K through the opening it, up through the tube K, and be forced out of the opening 70 back again into the said reservoir K hence the rod M will be thoroughly lubricated and no oil will escape from the top of the device K. In the reservoir K cotton-waste or other filtering substance,

as shown at p, is placed for filtering the oil from impurities or foreign substances before it enters the tube K. These belt supporting and guiding devices K are designed to be secured in the arms I at about the angles as shown in Figs. 1 and 2, so that a sufficient quantity of oil can always be retained in the reservoirs K for the lubrication of the rods-or shafts M.

The oiler is operated by passing an endless cord or belt, P, around the shaft A, and thence over the sheaves N N, that are held a suitable distance apart by a bent rod or stretcher, O, which extends between the arms K and is then crossed around the sheave H the said parts moving in the directions of the arrows, Figs. 1 and 2. Oil from the drip-pan D is pumped up by the revolution of the pump-rod H and delivered through the spout F into the journal-box oil-opening d, the turning of the cock 0 regulating the flow thereof. All the oil running out of the journal-box B flows back into the drip-pan D, and all excess of oil raised by the pump is expelled through its openings g 9 and also flows back-to the tank D for further use hence no oil is wasted.

In the belt supporting and guiding devices K the operation is analagous, the oil making acontinuous circuit of the tubes and reservoirs K K so that the'lubrication of the rods M is automatic.

With this oiler applied to lines of shafting an d machinery of various kinds great economy in oil can be effected, and all dust and other lateral overflow-openings g 9 and screw-rod H, having bottom screw-threads for raising the oil and top screw-threads for forcing the oil down, and provided with sheave H substantiall y as herein shown and described.

2. In amachine-oiler, the combination, with the hanger E and pump F H, of the pivoted slotted arms I I and screw-hooks and nuts L L, substantially as herein shown and described, whereby the belt supports and guides are adjustably held, as set forth.

In a machine-oiler, the combination, with the pumpFH and adj ustable-supporting arms I, of the belt supporting and guiding devices K, consisting of tubes K, attached oil-reservoirs K arm K and screw rod or shaft M, carrying sheaves N, substantially as herein shown and described.

4. The combination, with the drip-pan D and shaft A, of the screw-pump]? H, provided with filter G, adjustable arms I, belt supporting and guiding devices K, and belt 1?, substantially as herein shown, and for the purpose described.

JOHN SCOTT WHITNEY.
