AXLE SKEIN AND BOX.

5PECIPICATION forming part of Letters Patent No. 311,774.-, dated February 3, 188 5.

' Application filed June 5, 1884. (X0 model.)

To all whom it may concern;

. Be it known that I, WILLIAM BUGG Mniicrr AM, a citizen of the United States, residing at Boydton, in the county of Mecklenburg and State of Virginia, have invented certain new and useful Improvements in Axle Skeins and Boxes for Vehicles, of which the following is a description. I

Figure 1 is aside view of the axle with its box in section. Fig. 2 is a verticallongitudt nal section of the axle and skein. Fig. 3 is a plan view of the metal section B. Figs. '4 and 5 are details of the parts D and f.

The object of my invention is to reduce the frictionand facilitate thelubrication of vehicleaxle bearings, and to improve and strengthen the same, as will be hereinafter more fully de scribed.

In the drawings, A represents the axle, which for wagons, carts, 820., is preferably made of wood, but which may in some cases be made of metal. The under side of this axlearm is recessed or cut away to about half its thickness, and the recess extends back under the axle beyond the axle-arm. In this recessed place is fitted a metal section, B, which completes the outline of the axle-arm and the outer end ot'the axle. This metal section and the axle are held together by the following means: At the outer end of the metal section is formed an undercut flange, a, with ears or lugs b b on each side of the same, and under this flange, and between the lugs b b, the end of the axle is fitted to prevent lateral displacement. At the back end the metal section B is provided on its inner face with the projections c, which enter holes in the axle and prevent lateraldisplacement at that end, while a stout clip or metal strap,C, passes around the metal section B and clamps it to the axle and to the metal capplate D above, the said metal strap being secured by screw-nuts underneath, as shown. This upper plate, D, is provided with projections d, which fit into holes in the top of the axle to prevent lateral displacement, and said plate extends over the top of the axle a greater distance than the section B does underneath it, so as to cause said upper plate, I), to shoulder upon the full thickness of the axle, and thus impart greater strength to the arm. To

the lower metal section, B, there is cast, or with it is formed in one piece, a flange, B, which fits against the end of the axle at the inner end of the arm and forms a metal hearing. is formed a longitudinal channel, in which there is arranged in bearings the revolving skein S, which has two bearings, e 6, upon the axle-box. This revolving skein has its outer end fitted in a socket in the outer end of the section B, and its inner end is retained by a plate, f, clamped by strap 0, which platef also forms a sand-guard.

For lubricating this revolving skein,several holes, y g g, extend through the metal section B and conduct oil from the longitudinal channel h in the upper face of the section B to the bearings of the revolving skein. This channel h communicates through a perforated rubber block, '6, with an oilreserv0ir,j, in the upper face of section B. Around this reservoir and along the sides of the channel h is a raised flange or wall, It, which, when the section B is tightly clamped against the axle, forms an oil-tight joint. In the upper capplate, I), is formed an oil-cup, Z, having an opening in the bottom that registers with a hole, m, through the axle,leading to the oilreservoirj. This oil-cup Z has a screw-threaded cover, at, to keep out dust and dirt.

To regulate the flow of oil from the reservoir to the skein-bearings, a set-screw, n, is tapped through the metal section B of the axle, and is made to bear against a steel plate, 0, which in turn bears against the perforated rubber block t, so that by turning this setscrew in or out the size of the holein the same and the flow of oil therethrough may be increased or diminished.

E is the upper metal skein-bearing of the axle-arm. This is in the nature of a strip of metal inserted under the metal flange at the outer end of the arm, and having at its inner end an upturned portion, p, that enters a hole.

or recess in the flange d of cap-plate D, and by which it is heldin place in connection with one or more screws passing through it into the axle'arm.

F is the axle-box, which is in the nature of a tapering metal-sleeve having a flange, (1, .at

In the lower side of the metal section B L its large end and ribs 1* to tightly hold it in the hub against turning. The outer end of this axle-box is screw-threaded a short distance, and after it is inserted and driven into the hub a screw-collar, s, with notches for a wrench, is turned upon the same so as to clamp the hub between it and the flange (1 at the other end, thus tightly holding the box to the hub without the necessity of wedging. To prevent the screw-flange from being accident ally turned off by friction of the wheel in revolving, the direction of the screw-thread is such that it has to be turned in the opposite direction to that of the wheel to take it oft.

Having thus described my invention, what I claim as new is 1. The combination, with an axle having its arm cut away on its under side, of a metal section, B, having overhanging flange a, the capplate D, and the strap'or clip 0, as and for the purpose described.

2. The combination, with the axle, of the metal section B, having overhanging flange a, the metal strip E, having upturned end 1), the plate D, having a recess to receive said upturned end, and the metal strap 0, as and for the purpose described.

3. The combination, with the axle having oil-hole m,of the plate D, having oil-cup Z, the metal section B, having oil-reservoirj, channels h and g, and the revolving skein S, as and for the purpose described.

4. The metal section B,having oil-reservoir j and channel h, with a raised wall or rib around the same, in combination with the axle and means for holding them together, as described.

5. The combination, with the metal section B, of the revolving skein S and the retainingplate f and means for clamping it to the section B, substantially as described.

6. The combination, with an axle-arm having therein an oil-reservoir anddistributingchannels, of a perforated rubber block interposed between the reservoir and channels, and a set-screwfor varying the size of the hole in the rubber block to regulate the admission of oil, substantially as shown and described.

7. The metal section B, having flange B, in combination with the axle, the cap D, having flange d fitting down upon B, and the strap 0, as shown and described.

The above specification of my invention signed by mein the presence of-two subscribing witnesses.
