SHAFT-HANGER AND LUBRICATOR THEREFOR.

SPECIFICATION forming part of Letters Patent No. 553,676, dated January 28, 1896.

Application filcdMarch 25, 1895. Serial No. 54=3,076. (N0 model.)

T0 on whom it may concern Be it known that I, JOSEPH E. HOPPEN, a citizen of the United States of America, residing at Newark, in the county-of Essex and State of New Jersey, have invented certain new and useful Improvements in Shafting- Hangers and Lnbricators Therefor, of which the following is a specification.

My invention has reference to improvements in the construction of shafting-hangers and in means for lubricating the boxes thereof.

It has for its objects, first, to provide a hanger in which the box is readily adjustable with respect to the shaft and in which all the drip-oil is positively conducted to the drip-cup and prevented from dropping to the fioor, and, secondly, to provide a detachable capillary oil-cup for such hangers. To this end I provide the hanger with two yokes having concave surfaces surrounding the journal-box, of which the lower yoke is provided with an orifice through which part of the waste oil is discharged and through which the stem or nipple of a detachable oil-chamber provided with a drip-chamber is passed and connected to the box.

The nature of my invention will best be understood when described in connection with the accompanying drawings, in which Figure 1 is a sectional elevation of a hanger embodying my improvement. Fig. 2 is a vertical section in the plane 2 2, Fig. 1. Fig. 3 is a vertical section on an enlarged scale, part being broken away. Fig. at is abottom view with the oil and drip cup removed. Fig. 5 is a vertical section illustrating a spring wicktube for the oil-cup, part being broken away. Fig. 6 is a bottom view of the lower half of the box.

Similar letters of reference designate corresponding parts.

Referring now to the drawings, the letter A designates the base of a hanger.

B B are twoscrew-rods, the upper threaded ends of which are screwed firmly into the base. At the lower ends of the sore w-rods are located two yokes O C properly bored out to pass over and be movable on the screw-rods. The

yokes are provided with cavities c c, and the box D is provided with corresponding convex portions (Z (1 fitting into said cavities in the respectively above and below the yokes.

yokes. These cavities and projections permit angular adjustment of the box in a horizontal and vertical plane.

6 is a set-screw passing through the upper yoke and adapted to be screwed down upon the box D for securing the same after adj ustment.

7 The yokes C C are adjusted vertically upon the rods B B and secured at the proper height by means of nuts f located on the screw-rods In .the lower yoke is formed an orifice j, approximately below the center of the box D, for the discharge of the oil which oozes from the joints of the split box. This orifice also serves for the passage of the attaching-nipple g of the combined oil and drip cup from which oil is fed by capillary action to the bearing. The nipple g is tightly screwed into the upper part of a casting comprising the oil-chamber G and the surrounding drip-chamber H. The oilchamber is provided with a series of openings 9 for filling the same. Within said oil-chamber. G and extending upwardly to the bearing of the shaft is located a wick I. Said wick is encircled by a spiral spring J, which latter is compressed when the oil-cup is applied and holds the upper end of the wick constantly in contact with the shaft. The oil oozing from the ends of the box D is directed to the dripchamber H by means of two downwardly-tapered triangularly-shaped conveyers h preferably cast on the box and having their inner and lower ends located above the drip-chamber. By the use of these conveyers I am enabled to employ a much smaller drip-cup than heretofore.

The spiral spring J may be replaced by a split or perforated tube 1 encompassing the wick and pressed upwardly by a spiral spring I attached to its lower end and bearing against the bottom of the oil-chamber.

hat I claim as new is 1. The combination in a hanger, of a base, two screw rods secured to the base, two yokes provided with concave bearings and adjustably supported on said screw rods; the lower yoke being provided with a vertical orifice, a journal box fitted to said concave bearings of the yokes, and provided with a vertical threaded opening, an oil cup provided with a nipple passing through the orifice in the lower ICO yoke and screwed into the journal box, and means for transferring the lubricant from the oil-chamber to the shaft bearing, substantially as described.

2. The combined oil and drip cup for hanger or journal boxes herein described, comprising a drip chamber, a chamber for the lubricant located centrally, and in its entirety within said drip chamber, a spring pressed wick placed within the lubricant chamber, and a nipple secured to the lubricant chamber for the attachment of the combined oil and drip cup to the box, substantially as described.

The combination with a hanger or journal box provided on its bottom with convey ers extending inwardly and downwardly from its outer edges, of a drip cup located below the conveyers, so as to receive the oil dripping from the inner ends of said conveyors, and an oil cup located within the drip cup and provided with a wick for conveying the lubricant to the bearing, substantially as described.

4. The combination with an oil cup, of a Wick, a split tube encompassing and clampin the wick, and a spiral spring attached to the lower end of said tube and bearing against the bottom of the oil cup for pressing the wick upwardly, substantially as described. I11 testimony that I claim the foregoing my invention I have signed my name in presence of two witnesses.
