SPECIFICATION forming part of Letters Patent No.y 377,697, dated February 7l 1888.
v Application filed J' une 24, 1887. SerialNo'. 242,378. (No model.)
To aZZ whom it may concern.-
Beit known that I, THOMAS TRIrP,ofStougl1 ton, in the county of Norfolk and State of Massachusetts, have invented certain newand useful Improvements in Anti-Friction Journal- Boxes, of which the following, taken in connection with the accompanying drawings, is a specification.
The object of myinvention is to produce an' efticient anti-friction journal-box, and my invention relates to anti-friction bearings designed for general use. It is also designed to be an improvement of devices as shownd and described in United States Letters Patent granted to me August 4, 1885, No. 323,468.
lt has for its object simplicity of construction, perfection in detail, and completeness in its capacity as a simple, strong, durable and effective anti-friction bearing.
I will illustrate my invention as applied to a car-axle box designed for use under streetcars.
Figure 1 represents car-axle box` in plan. Fig. 2 is a sectional elevation of Fig. 1 on section line 5 5. Fig. 3 is a transverse sectionalv View of Fig. 1 on line 6 6. Fig. 4 is afullsectional view of Fig. 2 on line 7 7.
The caraxle box 8 is provided with'the spring- holder frames 9 and 10, which are secured to the main portion of the box by means of webs, as shown. `The spring-holder frames and webs are of the ordinary style. The box 8 is provided with the inner head, 11. It is also provided with the cap 12, which is bolted to box, as shown. The circular bearing 13 is fitted in its place and is held in its position circumferentially by means of thelugs 14 and 15, which are cast in the box. It is held longitudinally by means of the thrust-plate 16, which,when cap 12 is bolted to the box, holds the bearing rnily between the inner head and thrust-plate. The box is provided with the grease-cup 17, which communicates with the interior of the bearing by means of the slots 18 19 20, which extend from grease-cup through the box and bearing. The grease-cup is provided with the cap 21,Which is fastened to the cup by means of bolts, as shown.
The axle 22, part of one end of which is shown in section in Fig. 3, has fitted to it the sleeves 23, 24, and 25,which are longitudinally in Contact With each other,and which are held longitudinally in place by the end of the sleeve 23 being in contact with the car-wheel hub 26, (shown in partial section in Fig. 3,) and by one end of the sleeve 25 being in contact with the circularaxle-washer 27. Theaxle is provided with the thrust-stud 2,8, which is securely screwed into its outer end.
The axle-,Washer 27 is held central with the axle by' means of the thrustfstud, over which it fits, and is held rotatively fastened to the end of axle by means of center pin or dowel 29, one end of Whichis fastened to end of axle and the other end projecting from axle into v axle-washer, as shown.
The thrust-plate 16 is provided with the circular thrust-packings 30 and 31. The thruststud 28 is provided with the screw-threaded circular washer and nut 32 and check-nut 33. 7o The packing 34 is forced and held in its position by means of circular packing-plate 35, which is bolted to inner head, 11, by means of bolts, as shown.
The oil-hole 36, which extends through box and circular bearing, .is provided with the slotted screwplug 37 i l.
The roller-carrying ring 38,. the outside diameter of which is less than the inside diameter` of the circular bearing, and the inside diameter of which is greater than the outside d'iameter of the sleeve 25, is provided with, the series of roller-carrying pins 39, which are securely fastenedv to the ring 38, and which project beyond both sides of the ring, vas shown. The two series of rolls'40 and 4l are mounted on saidy pins, and are free to rotate thereon. The length ofy each roll is a little less than the space adapted to receive it, so that it will not be liable to receive any end resistance to its rollingaction when in use. The diameter of each Vroll is the same or a little less than the space betweenthe'sleeve 25 and the circular bearing 13, adapted to receive it.
The thrust-plate 16 is held in its position in contact with the circular bearing 13 by meansofthe clamping action of the cap 12 when bolted to car-axle box. i
Having described in detail the construction of my device, all parts of which may b'e made of any well-known suitable material, I will describe the method of putting the parts together. 1
One end portion of the axle 22 is turned to IOO a given diameter from the wheel-hub 26 toits extremity. Into the end of the axle is secured the thrust-stud 28. The center pin, 29, is also fastened to end of axle. The sleeve 23 is then forced upon the axle against the wheel-hub. The packing-plate 35 and packing 34 are then placed upon the sleeve 23. The car-axle box 8, to which the circular bearing 13 has been fitted, is then placed so that the inner head, 11, will rest upon the sleeve. Then the sleevesection 24 is forced upon the axle against the sleeve 23. Then the sleeve 25 is forced upon the axle against the sleevesection 24. Then the roller-carrying ring 38, with its series of pins 39 and series of rolls 40 and 41, is placed upon the sleeve 24 in its position between the sleeve and circular bearing. The axle-washer 27 is then placed upon the thrust-stud 28 against the end of axle and sleeve 25. The center pin, 29, rotatively secures the axlewasher to the axle. The thrust-plate 16, into which the thrust-packing 30 and 31 have been fitted, is then placed in its position over the thrust-stud 28 and against the circular bearing 13 and lugs 14 and 15. The washer and nut 32 is then screwed on-the thrust-stud uutil it comes in contact with a shoulder upon the stud, which is made on the stud at such a distan-ce from the end of the axle as will permit the placing of the axle-washer 27, thrustpacking 30, thrust-plate 16, thrust-packing 31, between the end of axle and sleeve 25, and washer and nut 32. The check-nut 33 is then screwed against the washer and nut 32, so as tooperate as a check-nut. The cap 12 is then bolted to car-axle box 8, thereby firmly clamping the thrust-plate between the cap and circular bearing and lugs. The packing 34 is then forced into its position against the inner head, 11, by the screwing up of the bolts, which fastens packing-plate 35 to inner head. Then my device is ready for use. The inside diameter of the packing-plate 35, and of the inner head, 11, is greater than the outside diameter of the sleeve 23, and the inside diameter of the thrust-plate 16 is greater than the diameter of the thrust-stud 28, so as to al low sufficient clearance to permit the wearing of the series of rolls 40 and 41 and circular bearing 13, and at the same time to prevent contact between the packing-plate and inner head and sleeve, and also between the thrustplate and thrust-stud. The packing 34 is made and made up in such a manner, as shown and described, as to make an oil-tight joint. The thrust-packings 30 and 31 are also made and made up, as shown and described, so as to make oil-tight joints.
Some of the special advantages afforded by my device are as follows:
The sleeve device may be made in one or more sections. The sleeve 25,when worn, can
be taken off the axle without injury to the axle and a new one forced on.
The circular bearing, when worn, may be taken out of the box and a new one put in without any special trouble or expense. The end thrusts of the axle are received by the thrust-plate mechanism, and the injurious effects of the thrusts or blows are absorbed to quite an extent by the thrust-packings 30 and 31. The thrust-packings 30 and 31 and packing 34 prevent the escape of oil from the interior of the box. In using the axle-washer 27 a good thrust-bearing surface is obtained. The arrangement of the oiling devices is complete and cleanly.
The entire device consists of perfected details, which, while performing their various duties in a most satisfactory manner, make the car-axle box an anti-friction box, durable, complete, effective, economical, and cleanly.
What I claim, and desire to secure by Letters Patent, `is- 1. In an anti-friction journal-box, the combination of the axle 22, provided with sleeves 23, 24, and 25, and thrust-stud 28, with thrustplate 16, provided with thrust-packings 30 and 31, and washer and nut- 32, substantially as described.
2. The combination of an axle provided with a removable sleeve and thrust stud, with axle-washer 27, thrust-plate 16, provided with thrust-packings, washer and nut 32, packing 34, and packing-plate 35, substantially as described, and for the purposes set forth.
3. The combination of the following elements, substantially as described: roller-carrying ring 38, provided with pins 39, and rolls 40 and 41, axle 22, provided with sleeves 23, 24, and 25, and thrust-stud 28, thrust-plate 16, provided with thrust-packings 30 and 31, and washer and nut.
4. The combination of the following mechanism, substantiallyas and for the purposes set forth: roller-carrying ring 38,provided with pins 39, and rolls 40 and 41, axle 22, provided with removable sleeve, and axle-box 8, provided with removable bearing.
