MECHANICAL OILER FQR SHAFTING.

SPECIFICATIQN forming part of Letters Patent No. 553,512, dated January 28, 1896.

Application filed February 27, 1895. Serial No. 539,845. (No model.)

To all whom t may concern.-

Beit known that I, GEORGE H. COLE, a citizen of the United States, residing at Lowell, in the county of Middlesex and Commonwealth of Massachusetts, have invented a certain new and useful Improvement in Mechanical Oilers for Shafting, of which the following is a specification.

My invention relates to mechanical Oilers i for shafting; and it consists in the combinations hereinafter described and claimed, the object of the same being to feed the oil continuously in large quantities from a reservoir in the journal-box t0 the journal-bearing, to return the surplus oil to said reservoir, and to prevent the oil from getting beyond the ends of the j ournal-box, running to waste and dirtying the shafting and the floor beneath and articles resting upon the floor.

In the accompanying drawings, on two sheets, Figure l is a plan of a piece of shafting provided with a collar and arranged in a journal-box, said box and my improvement; Fig. 2, a vertical central longitudinal section of said journal-box and the toothed Oilerring, showing said shafting and the oilershaft pulley and pinion in front elevation; Fig. 3, a front elevation of a part of the journal-box, shafting, and oiler-shaft, showing' the oiler-shaft provided with a face-wheel and the shafting provided with a fast gear; Fig. 4, a side elevation of said face-Wheel and fast gear; Fig. 5, a plan of the journal-box, shafting and movable deflector, the cover being removed to show the oiler-shaft and its pinion and the oiler-ring.; Fig. 6, a plan of the lowerhalf of the journal-box, the shaftin g and collar, the oiler-ring,y the Wipers, a stop-ring and packing-ring, one of said wipers, the posts which support the lower half of the Babbitt metal lining and the oil-passages which lead from the opening between the babbittings to the reservoir, being shown in dotted lines; Figs. 7 and 8, vertical transverse sections on the lines 7 `7 and 8 8, respectively, in Fig. 2; Fig. 9, a front elevation of the adjustable oil-deflector detached; Fig. 10, a plan ofthe oil-wipers and adjacent parts of the lower babbit-ting; Figs. 11 and 12, respectively, a front elevation and a side elevation of a part of the oiler-ring and the pinions connecting said ring and the oiler-shaft, by which the surface speed of said oiler-ring may be made different from that of the shafting to be oiled,

parts of the cap of the journal-box being shown in central longitudinal section in Fig. 11, and the shafting being in front elevation in Fig. ll and in vertical cross-section in Fig. 12.

The piece of shafting A may be provided with a fixed collar a to prevent end movement of said shafting in the usual manner.

The journal-box B consists of a cap B and a lower half B2, in which the shafting A is supported. The lower half B2 is provided with ears b, by which the box B is supported in the usual manner in any hanger. Said lower half B2 is provided also with an oilreservoir b2, which extends nearly from end to end of the same, and with vertical posts b4, preferably cast or otherwise formed in one piece therewith, upon which posts rests the lower babbitting C', the upper portions of said babbitting being held between the sides of said lower half.

The box B has an annular enlargement b vat the middle thereof to receive the toothed oiler-ring D, hereinafter described, and to allow thesame to run freely out of Contact with said box and the lining or babbitting C of the cap B, which lining C has the same thickness at c within said enlargement b' as where said lining comes in contact with the shafting A. J ust outside of the babbitting or lining C said lower half is'also provided at each side thereof and at each side of the enlargement b' with a horizontal groove bs, which extends from said enlargement to the ends of said lining, said grooves bs receiving the lower edges of the cap B and discharging any oil which may work into said grooves bs into cylindrical drip-receiving chambers b3 cast in and continuous in both halves of the box B, Figs. 2 and 6. 'The outer edges of the lower lining C are beveled at c2 to form with the inner face of the lower half of the box grooves which descend slightly fromv the middle toward the ends of said box, as indicated by the dotted line c2 in Fig. 2, so that any oil which is caught between said lining C and the lining C of the cap B runs along in the spaces between said beveled edges o2 and the horizontal. edges es of the lining C and is discharged into the reservoir b2 through grooves bm, formed in the IOO inner faces of the lower half and reaching from the top of said lower lining C to the top of said reservoir.

The ends of the lower lining C are provided with projections c' or Wipers, Figs. 2. and (i,

' which remove the oil from the shafting A and allow the same to fall into the reservoir in order to prevent, as far as possible, the oil from crawling along on said shafting and out of the ends of the j ournal-box. If the shafting is intended to run always in the same direction the front side c of the wi per c, or side toward which the oil is carried, should be inclined to the axis of said shafting in such a manner as to direct the oil toward the body of the lining C', and the rear side c5 of said wiper should also be inclined in the same direction, as shown at the right in Fig. G; but if the shafting is intended to run in each direction, at will, both sides cG of said wiper should be parallel with said axis. I also provide near each end of the box B, in the top of the cap B and just beyond the ends of the lining' C, a nearly tria-ngular hole D7, Fig. 5, in Which is placed a deiector E, preferably of metal, and hinged to said cap B' bya staple-shaped hook e, one arm of which enters a vertical hole e in said dei'lector near the outer edge of said deflector, and the other arm of which hook c enters a hole b5 in the cap B, Figs. 2 and 5, in such a manner as to allow said delector to be swung by the friction of the shafting A `on the bottom thereof to cause oil carried by said shafting beyond the ends of the lining' to be turned toward said lining.

As a further precaution against the oil reaching the ends of the journal-box, I surround the shaftin g A, between the defiectors E and the ends of said box, with stop-rings F, of any material, which iit said shafting closely and prevent the oil from passing between said shafting and said rings F, and which may be readily secured in place, preferably using leather strips, the ends of which are fastened by wire belt-hooks f of ordinary construction.

Such oil as, notwithstanding the Wipers e.

and deilectors E, reaches the stop-rings F will be thrown by centrifugal force from the eircumferences of said stop-rings into the box B and iiow back to the reservoir.

Dust and lint are excluded from the box B by means of packing rings or strips G inserted in grooves Z915 bm, substantially in the manner shown in my Patent No. 515,745), dated March 6, ISM.

The oiler-ring I) surrounds the shafting A and rests thereon, as described in said previous patent, but instead of being a mere ring carried by the direct friction of said shafting thereon is an annular gear, driven by an oiler-shaft II, provided with a pinion h', which may directly engage the teeth d of said ring D, as shown in Figs. 2, 5 and 7, said oiler-shaft H being rotated by a Wheel which may be a friction-Wheel 7L, fast on said shaft H and driven by contact with the shafting A, as shown in Figs. l, 2 and 5, or a gear 7L,

fast on said shaft II and engaging another gear 7a4, fast on the shafting A, as shown in Figs. and i, where the gear h5 is represented as a face-gear or contrate-gear and the gear 7L* is represented as a ring having teeth on the edge thereof.

The arrangement shown in Figs. 3 and i gives to the oiler-ringapositive motion in the same direction of revolution as that of the shaft, causing the contiguous surfaces of said oiler ring and shaft to travel in the same direction.

By using any other odd number of engaging pinions in place of the pinion h to conneet the oiler-shaft and the oiler-ring, said ring will still be caused to rotate in the same direction as said shafting A, and by making one of these pinions a compound pinion or a compound gear, as shown at h3, Figs. Il and l2, the speed of said ring may be reduced below that of said shafting, which lessens the liability of the oil to be so violently agitated as to be driven beyond the journal-surface of the shafting to become iilled with air-bubbles, which diminish the lubricating quality of the oil.

A guide-cap I, Figs. 2, 5, 7, and S, is provided with notches t' Q1 to allow said guidecap to be placed down in the chamber b oi' the cap B and over the pinion 7L', or over the Series or train of pinions shown in Figs. Il and l2, and prevents any endwise movement of the oiler-sh aft, which lies looselyin a groove Z211, reaching down from said chamber b9 to the end of the box B, said chamber Zi and groove b being closed by a suitable cover J, having a suitable shape to iill said chamber and having a iiangej to rest upon the top of the cap I3.

The oiler-ring I), for convenience of application to the shafting, may be made in two parts d d2, halved together at d3 and secured to each other by pins (Zt (Shown in Figs. G and 7.)

I claim as my invention*- l. The combination of a j ournal-box havin g' a suitable reservoir, atoothed ring or annular gear adapted to surround and rest upon a piece of shafting supported in said journalbox, and to enter the oil in said reservoir, an oiler-shaft having a fast pinion adapted by its rotation to rotate said oiler-ring and having a wheel fast thereon and adapted to engage said piece of shafting and to be rotated thereby, as and for the purpose specified.

2. The combination of a journal-box having a lower half provided with a suitable reservoir and having a cap provided with a chamber, a toothed ring or annular gear adapted to surround and rest upon a piece of shafting supported in said journal-box, and to enter the oil in said reservoir and an oiler-shaft having a fast pinion adapted by its rotation to rotate said oiler-rin g and to enter said chamber and having a Wheel fast thereon and adapted to engage said piece of shafting and to be rotated thereby, and a guide-cap, hav- IOO IIO

ing notches and adapted to be placed in said chamber over said pinion and oiler shaft, as

' and for the purpose specified.

tional contact of said shafting, to direct oil escaping from said lining along said shafting back toward said lining, as and for the purpose specified.

In Witness whereof I have signed this speciiication, in the presence of tWo attesting Witnesses, this 21st day of February, A. D.1895.
