OLAUS B. JACOBS, OF FREMONT, VVASl-IING'ION.k
CAR-AXLE BEARING.
SPECIFICATION forming part of Letters Patent No. 501,790, dated July 18, 1893. Application led November lll, 1892..` Serial No. 451,920. (No model.)
To @ZZ whom it may concern:
Be it known that I, OLAUS B. JACOBS, of Fremont, in the county of King'and State of Washington, have invented a new` and improved Car-Axle Bearing, of which the following is a full, clear, and exact description.
The object of the invention is to provide a new and improved car axle bearing more especially designed for use in railway and street cars, and which is simple and durable in construction, and arranged to reduce the friction to a minimum, to eliminate friction from lateral and transverse thrusts, insuring longer wear, and which is easily applied and arranged to give the required strength within a small space.
The invention consists of a series of rollers adapted to travel on the axle and pass between the latter and the brass, the said rollers being mounted on ball bearing spindles held in rings.
The invention further consists of an end thrust plate held on the brass or box, and a ball bearing interposed between the plate and the end of the car axle.
The invention also consists of certain parts and details, and combinations of the same, as will be hereinafter described and then pointed out in the claims.
Reference is to be had to the accompanying drawings forming a part of this specilication,
- in which similar letters of reference indicate corresponding parts in all vthe figures.
Figure l is a sectional side elevation of the improvement. Fig. 2 is a front view of the same withl the lid of the box removed. Fig. 3 is a transverse section of the same on the line 3-3 of Fig. l. Fig. 4C is an enlarged sectional front view of the ring and ball bearing spindles on the line 4 4 of Fig. 5. Fig. 5 is a sectional side elevation of the same on the line 5--5 in Fig. 4. Fig. 6 is a sectional side elevation of a modified form of the improvement. Fig. 7 is a sectional side elevation of a modied form of the improvement. Fig. 8
is a face view of the roller spindle ring for the modified form. Fig. 9 is a sectional plan view of the same on the line 9--9 of Fig. 8; and Fig. l0 is a face view of the rear roller spindle ring.
The axle A, of the usual construction is engaged at each end by a series of rollers B held on sets of balls C, each set surrounding a spindle D on cones E, E' attached to the said ball bearing spindle D near each end thereof, the said cones itting loosely into recesses formed in the end of each roller B, each recess containing a set of balls C. The spindles D are held in rings F and F', and are placed suitable distances apart and arranged in a circle and the rollers B engage the axle A and roll o on the same, so that a series of such rollers are always interposed between the axle A and the brass G rounded at its under side, concentric to the axle.
On the top of the brass G are arranged rollers H, extending longitudinally at right angles to the axle and supporting on their top the box I, as plainly shown in the drawings.' Bearing ballsH, are arranged at the corners of the brass Gr to abut against the sides of the box and part of the top, to re- ,duce the friction of the brass within the box to a minimum. Each of the ball bearing spindles D is fitted to slide radially in radial slots F2 and F2, formed in the rings F and F respectively, the rear slot F3 being partly formed square to receive the correspondinglyshaped head D of the respective spindle D, to prevent the latter from turning. The front threaded end of each spindle D is engaged by a nut D2, screwing against the front face of the ring F so as to take up any wear on the balls C, the seats for the same in the rollers B and the cones E, E', being formed on the respective spindle. In order to adjust each spindle D in the slots F2 and F3 set screws J are provided, screwing in the rings F and F', and abutting with their inner ends on the spindles, as plainly shown in Fig. 1.
In order to securely hold the cones EEY in position on the spindles D and to permit the saidcones to slidewith the spindles when they are adjusted by the set screws J, I provide a pin-K for each cone, the said pin being fastened in the respective ring F or F and projecting into a recess formed in the IOO A or thebox I, I attach to the brass'G or to the casing,asshown in Fig. 6, a thrust plate L, fastened by countersunk screws or other means L to the brass G, as plainly shown in Figs. l and 2. This thrust plate L extends in front of the axle A and is engaged at its rear by balls N, arranged in a recess A ,formed in the outer end of the axle A. The balls N roll on a pin O, extending in an axial line from the axle A, the said pin passing loosely through an aperture in the thrust plate L, as plainly shown in Fig. l. The front surface of this thrust plate is engaged by a second Vset of balls P, located directly opposite the balls N and held in a nut O', screwing on the Vouter threaded end of the pin O. A key O2, or other means serves to loclrthe nut O in place on the end of the pin O. The inner face of the nut O is recessed as illustrated in Fig. l, to receive the balls P resting on the outer surface of the thrust plate L, as above described, so that any end thrust either in an outward or inward direction, is taken up by the sets of balls N and P, pressing on the thrust plate L on opposite sides thereof.
In order to prevent the upper end of the thrust plate from rubbing on the lid or cover I of the box I, I provide the inner surface of the said cover with a lining Q, preferably made of paper and in the shape corresponding to the upper part of the thrust plate L, so that when the latter moves outward it rubs against the lining instead of passing directly onto the lid or cover I. This lining Q is secured in place by screws and washers Q', each of which is adapted to pass into a recess L2, formed in the thrust plate at the front face thereof, so that when the thrust plate rubs against the lining, the head of the screw and the washer pass into the respective recess L2 to prevent the head and washer from coming in contact with the metallic face of the thrust late.
p As illustrated in. Fig. 6, the set of balls N is not arranged in the recess A of the axle A, but in a separate cup A2, secured on the pin O at the end of the axle A, as shown, the said cup extending about in line with the ring F. In this modified form the rollers B are formed on each end with an annular flange B, which fits between the cup A2 and the axle' A, and also abuts against the shoulder G2, formed on thebrass G. Thus lateral displacement of the roller B on the axle A is prevented.
In Figs. 7, 8, 9 and 10 is illustrated amodified form of spindle supporting rings F F', arranged for conveniently adjusting the roller spindles D radially. For this purpose each ring F or F is composed of an outer and an inner ring F4 and F5 respectively, of which the inner ring F5 is provided with radially extending slots FG for the passage of the spindles D and the outer ring F4 is provided with obliquely arranged slots F7 through which also pass the spindles D and which serve to move the spindles radially inward or outward' on turning this ring F'on the other ring F5. In order to turn the outer ring F4 on the other ring F5, I provide a screw rod T held with its head T in a lug F8 of the outer ring F4 and passing with its shank end through a lug F9 on the other ring F5. The nuts T2 of the screw rod T abut on this lug to lock the rod and ring in place, and by turning thenuts the ring F4t is turned on the other ring as the nuts press on the lug F2.
It will be seen by the construction described, that the friction of the several parts is reduced to a minimum, the wear is very little, as the rollers B pass successively between the axle A and brass G and at the saine time the end thrust is taken up by the sets of balls N and P, as above described. By adjusting the set screws J the spindles D can be adjusted in the radial slots F2 and F3, of the rings F and F', and by adjusting the nuts D2 on the said spindles, the wear on the walls and seats of the balls in the roller B can be taken up at any time. It will be further understood that the thrust of the sets of balls C is at or nearly at right angles to the faces of the cones E, E; hence wear on the cones is re` duced to a minimum.
Having thus fully described my invention, I claim as new and desire to secure by'Letters Patentl. A car axle bearing comprising concentric rings, spindles held radially adjustable in the said rings, and provided with ball bearings, and aroller journaled on the ball bearings on the said spindles, substantially as shown and described.
2. Acar axle bearing comprising concentric rings, spindles held radially adjustable in the said rings, and provided with ball bearings, a roller journaled on the ball bearings on the said spindles, and means, substantially as described, for radially adjusting the said spindles in the said rings, as set forth.
3. vA car axle bearing comprising rings, spindles held in the said rings, cones held on the said spindles, sets of balls held on the said cones and on each spindle, and a roller journaled on the said balls on each spindle, substantially as shown and described.
4. A car axle bearing comprising rollers, each having cup-shaped recesses in its ends, balls held in each recess, a spindle for each roller, and cones held on each spindle, and extending into the roller recesses to engage the balls contained in the recesses, substantially as shown and described.
5. A car axle bearing comprising a box, a brass held in the said box, a series of longitudinally-extending rollers interposed between the top of the brass and the box, rollers interposed between the axle and the under curved side of the brass, and balls H interposed between the corners of the said brass and the sides and top of the box, as set forth.
6. A car axle bearing provided with an end thrust plate secured to the brass and extending in front of the car axle, and ball bearings IOO v the front and rear of the said thrust plate, a
pin supported from the axle and surrounded by the said sets of balls, and means for holding the latter in place on the said pin, substantially as shown and described.
8. A car axle bearing comprising rings, spindles held on the said rings and each mounted to slide in radial slots on the said rings, cones -held on each spindle, and pins secured on each ring and engaging the base end of the corresponding cone, substantially as shown and described.
