GEORGE H. VILLIAMSON, OF SKANEATELES, NEV YORK, ASSIGNOR OF ONE- HALF TO STEPHEN THORNTON, OF SAME PLACE.

AXLE FOR HARVESTER-TRUCKS.

SPECIFICATION forming'partof Letters Patent No. 424,398, dated March 25, 1890. Application filed September 6, 1889. Serial No. 323,135. (Normodel.)

To @ZZ whom it may concern: Be it known that I, GEORGE H. VILLIAM- SON, a citizen of the United States, residing at Skaneateles,in the county of Onondaga, State of New York, have invented certain new and useful Improvements in Harvester-Castings, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in trucks designed, primarily, for use in moving reapers and binding-machines, although, of course, it is applicable to other uses.

The novelty resides in the peculiarities of construction and the combinations, arrangement, and adaptation of parts, all as more fully hereinafter` described, shown in the drawings, and then particularly pointed out in the appended claims.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this specification, and' in which- Figure l is a side view of the front bearing with the axle in place. Fig. 2 is a central longitudinal vertical section of the rear bearing with the axle in place. Fig. 3 is a front view of the front bearing with the axle removed. Fig. 1i is a vertical section on the line oc of Fig. 3. Fig. 5 is a vertical. section on the line y y of Fig. 3. Fig. 6 is a front view of the rear bearing with the axle removed.

Like letters of reference indicate like parts throughout the several views.

Referring to the details of the drawings by letter, A designates a casting formed with extension A', the upper face of which is curved or concaved, as shown, to conform to the shape of the tubular portion B of the frame, and with a substantially Z-shaped portion or iange A2, designed to be secured to the portion B of the frame by means of suitable bolts B2. This casting is also formed with an internal screw- 45 threaded portion A3, from which 'projects a ledge or rib A4, the opposite end of said screwthreaded opening being polygonal in shape, as shown at A5, to receive a correspondinglyshaped shoulder on the axle, as hereinafter 5o described.

B3 is a bolt passed through the tubular por- C is a pipe or tube secured in the casting 6o A by means of screw-threads engaging the threaded portion A3 thereof.

D is a casting in many respects similar to the casting A, and is formed with a` concave portion D to receive the tubular portion E of the trame and secured by means of the bolts D2. This casting has a screw-threaded portion having at one end a polygonal porltion to receive a correspondingly-shaped shoulder on the axle.

F is a tube or pipe screw-threaded at its ends and engaging the interior screw-threads of the casting D, there being of course two castings D and two castings A, one at each end of the tubes C and F.

G are the axles formed with tubular shanks G', which it within the tubes C and F, and are formed, preferably, with a polygonal shoulder G2, which fits the correspondingly-shaped socket in the castings and abuts against the 8o end of the tube, as shown clearly in Fig. 2, to prevent turning of the axle therein. The axles are otherwise formed in the ordinary manner with skein and screw-threaded end for the reception of a nut, as shown in Fig. 2.

The axles are secured in the tubes iirmly with the polygonal portions in the correspondingly-shaped socket by means of Wedgeshaped keys H, which pass through a suitably-shaped opening in the tubes and in the cylindrical 9o shank of the axle.

In order to aid in the removal of the axle from t-he tube when desired, in case it should bind therein, I have in the-tube a slot H', preferably at right angles to the slot or opening, through which the key passes, so as not to weaken the same, through which the key may be inserted after its removal from the slot, in which it is shown in Fig. 2, for the purpose of driving the axle out, the key acting like a 1o@ wedge against the inner end of the shank of the axle, forcing it out.

Various modifications may be resorted to Without departing from the spirit of my invention. For instance, the shank ofthe axle may be square or polygonal to t a correspondingly shaped tube or socket; or the shank of the axle may be secured in the tube or socket by means of a bolt passing` through the same; or the tube or socket may be short or in two pieces, the essence of the invention residing in the movable axle irrespective of its manner of attachment.

The tube in which the axle-arm is inserted may sometimes b e a part of the frame used on all machines, thereby saving an extra iron and also a saving of labor. It will of course be understood that the castings will be formed so as to fit differentlmachines.

1. The combination, with the casting and the tube held therein, of the axle having a shank fitted to said tube and formed with polygonal shoulder engaging a corresponding socket in the casting, substantially as described.

. 2. The combination, with the casting formed with concave portion to receive a portion of the frame, of a tube held in said casting and an axle having a shank secured in said tube, substantially as described.

3. The combination, with the casting having concaved portion to receive a portion of the frame and a screw-threaded portion with polygonal socket, of a tube engaging said screw-threaded portion, and an axle having a shank fitted in a tube and a polygonal shoulder engaging said socket, substantially as shown and described.

4. The combination, with the casting having concave portion to receive a portion of' the frame and screw-threaded portion with polygonal socket, of a tube having a screwthreaded portion engaging the threaded portion ot the casting, an axle having a shank fitting said tube and polygonal portion fitting said socket, and a wedge-shaped key passed through the tube and shank, substantially as described.

A5. The combination, with the casting having a concave portion to receive a portion of the frame and screw-threaded portion with polygonal socket, ot' a tube having a screwthreaded portion engaging the threaded portion of' the casting, an axle having a shank fitting said tube and polygonal portion fitting said socket, and a wedge-shaped key passed through the tube and shank, said tube having a slot H to the rear of the shank, substantially as described.

v6. The combination, with the casting having concave portion to receive a portion of the frame and a screw-threaded port-ion with polygonal socket, ot a tube having a screwthreaded portion en gagingthe threaded portion ot' the casting, an axle having a shank fitting said tube and polygonal portion fitting said socket, and a wedge-shaped key passed through the tube and shank, said tube having a slot II to the rear of the shank, said slot arranged at right angles to the one through which the key passes, substantially as described.

7. A castingforthe purpose described formed with concave extensions and threaded portion with polygonal sockets and a substan` tially Z-shaped flange, substantially as shown and described.

In testimony whereof I affix my signature in presence of two Witnesses.

GEORGE H. WILLIAMSON.
