CLAY FAULKNER, OF FAULKNER, TENNESSEE.

REVOLVING AXLE.

SPECIFICATION forming part Of Letters Patent NO. 722,218, dated. March 10, 1903.

Application filed May 28, 1902. Serial No. 109,325. (No model.)

To a, whom it puny concern.-

Beit known that I, CLAY FAULKNER, a resident of Faulkner, in the county of Warren and State of Tennessee, have invented certain new and useful Improvements in Revolving Axles; and I do hereby declare the following to be a full, clear, and exact description of the skilled invention, such as will enable others in the art to which it appertains to make and use the same.

My invention relates to an improvement in revolving axles, the object of the invention being to provide an improved steel channel axle-support and improved mounting therein for revolving axle-sections.

\Vith this object in view the invention consists in certain novel features of construction and combinations and arrangements of parts, as will be more fully hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a View in elevation illustrating my improvements. Fig. 2 is a View in section of the same. Fig. 3 is a View in section on the line as a: of Fig. 2. Fig. 4: is a view in section on the line y y of Fig. 2. Fig. 5 is a bottom plan view, and Figs. 6, 7, and 8 are views illustrating various details of construction.

1 represents my improved continuous steel channel axle support or bolster,which is bent into an inverted-U shape in cross-section and made of sufficient length to extend from one wheel-hub to the other. The axle support or bolster has sand-bands 2 secured to its ends.

On top of channel axle support 1 three wrought-iron plates 3 are riveted and made with gains for hounds 4 and coupling-pole, and to the bottom edge of the support at points on opposite sides of its center wroughtiron angle-plates 5 are riveted and have secured thereto braces 6, connected at their other ends with hounds a to brace the latter.

In the channel axle-support 1, near its respective ends, boxes 7 are mounted and are ribbed on the side faces, and the support 1 is grooved or recessed to receive the boxes. These boxes 7 are preferably made in two sections, as shown, but may be in one piece, if desired, the upper members lined with Babbitt metal or brass and provided on their upper face with a semispherical enlargement 7" to fit a correspondingly-shaped socket in the support 1 and the lower members made of solid malleable iron and provided with a pocket 8, the upper inner face of the support having a reinforcing-plate 7 riveted thereto adjacent to the socket therein to take up wear and prevent the boxes wearing loose. The pocket 8 is open at one end to receive a semicylindrical lubricant-cup 8, in which a spring 9 is located and adapted to press absorbent or other material 10 against the lower face of the axle-section 11 to insure a supply of lubricant thereto. The boxes 7 are secured in the support by means of clips 12, to which brace-rods 13 are connected, and secured at their outer ends to the hounds. Center boxes 14 are secured in support 1 on opposite sides of the center thereof and are of the shape shown, with hollow rounded enlargements 15 on their upper and lower sides, one of which to fit a correspondingly-shaped socket in the support 1 and the other to enter a socket in a plate 16, secured in place by a clip 17. The boxes 14 are preferably lined with Babbitt metal, and the enlargements are cored, forming receptacles for waste or absorbent material and lubricant.

ln boxes 7 and 14 axle-sections are mounted to turn and have secured on their outer ends the hubs 18 of suitable wheels, and said hubs are made on their inner ends with peripheral flanges 19 to prevent the passage of mud and grit to the journals. The inner ends of axle-sections 30, which terminate in close proximity to each other, are grooved peripherally to receive a box-shaped coupler 20, whose ends are grooved and enter the grooves in axle-sections 30 and inclose the inner ends thereof and prevent possibility of longitudi' nal movement of the axle-sections. This coupling 20 is held in position by means of a bar 21, secured at its ends to plates 16 by cap-screws 22, and the box-coupling is made hollow to hold lubricant and waste to lubricate the inner ends of the axle-sections. Boxes 14 and coupling 20 are each provided in one side with ducts communicating with. openings 23 in channel-support 1 for the admission of lubricant thereto. The openings 23 are all closed by a hinged plate 24, normally held in its closed position by aspring-arm 25, secured at one end to support 1. The boxes 7 are also provided in their tops with ducts alining ICO with openings 26in raised portions of the top of support 1, and said openings are normally closed by hinged plates 27, having raised portions to look over the raised portions of the support. The upper members of boxes 7 are grooved, as shown at 29, to communicate with lubricant-entrance ducts therein and convey the lubricantaround the axle to the pocket in the bottom thereof, from which it is supplied to the axle by the spring-pressed absorbent, as above explained. Suitable nutlocking malleable-metal strips 28 are located on the clips and are bent up against one face of the nuts to secure them against accidental removal.

In operation the axle-sections 3O revolve freely in boxes 7 and 14 and in coupling 20 and are held against longitudinal movement by the latter and lubricated at all of its bearing-points, as above set forth.

The steel axle-support l weighs about the same as wood and has proved by actual test to be very much stronger, cheaper, and in many particulars superior to wood.

A great many slight changes and alterations might be made in the general form'and arrangement of parts described without departing from my invention, and hence I do not wish to limit myself to the precise details set forth, but consider myself at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of my invention.

Having fully described my invention, what I claim as new,and desire to secure by Letters Patent, is

1. The combination of a continuous metal channel axlesupportorbolster,bearingblocks in said support, axle-sections mounted to revolve in said bearing-blocks and having peripheral grooves at their inner ends and a coupling box located within said channel axle-support and adapted to receive the grooved ends of both axle-sections and lock them against longitudinal movement, said coupling-box also adapted to receive lubricant.

2. The combination with a continuous steel channel axle support or bolster, of bearingblocks in said support, enlargements on the blocks to fit sockets in the continuous support or bolster, clips to hold the blocks in the support or bolster, and revolving axle-sections mounted in said blocks.

3. The combination with a channeled sup port or bolster, of bearing blocks secured therein and havinglubricant-receptacles,axlesections disposed within said channel support or bolster and mounted to revolvein said blocks, a spring in each receptacle, and absorbent material pressed against the axle by the spring.

4. The combination with a channeled axle support or bolster, of bearings secured therein each comprising two sections, soft metal lining one of said sections, a lubricant-receptacle in the other section, aspring in said receptacle, a revolving axle in said bearings, absorbent material on the spring and held thereby against the axle, and said bearing having a duct and grooves connecting the same with the lubricant-receptacle to guide the lubricant thereinto, the duct of each bearing extending through the wall of the channeled axle support or bolster.

5. The combination withacontinuous steel channel axle support or bolster and sandbands secured to its respective ends, of bearing-blocks in said support, axle-sections disposed in said channeled support or bolster and mounted in said bearing-blocks, hubs on said axle-sections, flanges on the inner edges of the hubs in the sand-bands and a coupling disposed within the channeled support or bolster and holding the inner ends of the axlesections against longitudinal movement.

6. The combination with a continuous steel channel axle support or bolster, of bearingblocks near the respective ends of said support or bolster and other bearing-blocks on opposite sides of the center thereof, axle-see tions disposed within said continuous support or bolster and mounted in said blocks and grooved near their inner ends, a coupling in said support or bolster recessed to receive said grooved ends of the axle-sections and hold them against longitudinal movement, lubricant-chambers in all of said bearing-blocks and in the coupling, and closures IOO
