Fig. 16 is a section of a modified form of axle construction.

In a machine of this character it IS usual to employ comparatively small front wheels to provide a bed low down to facilitate easy loading. As the machine must also turn very close, the front wheels in turning, run partly under the bed, which necessitates that the axle guides project a suflicient distance downward from the bed and hold the axle that the wheels can turn close without coming in contact with the bed, necessitating relative long axle guides. As the front axle is subject to severe forward and backward jars, as the machine travels over uneven ground and when the small front wheels hit obstructions or drop into furrows or other depressions, it is essential that these guides, which hold the axle in position, must be extremely strong and non-yielding in order that this purpose ma be accomplished.

he bed of the vehicle is shown in Fig. 2

and consists of longitudinally-extending sills 1n the form of L-beams 1, connected by angle iron cross-sills 2, and having secured to the outer side of the vertical web thereof uprights 3 of angle-iron to which are connected wooden sides 4. The boards 5 forming the bottom of the bed are laid upon the crosss1lls 2 and secured thereto in any suitable way. The two front members 3 on each side of the bed project below the side walls or beams 1, bein bent toward each other as indlcated at 3 1n Fig. 3 and thence projected downwardly in parallel relation, as indicated at 3 so as to form guides for the axle to be descnbed. For the purpose of stiffening these guide members the portions 3 have connected therewith a triangular-shaped plate 6 and the lower ends of the portions 3 are connected by a bar 7 Thefront axle is preferably formed of two angle-lron members 8, the edges of the horizontal and vertical webs of which are placed together so as to form a hollow structure which has a central filler member 9, this filler member and the two angle irons 8 being connected together at a midway point by a pair of r1vets 10, as shown in Figs. 1, 2 and 4. Each of the ends of the axle projects through the corresponding guides 3 and secured to each end of the axle is a U-shaped plate 11, the vertical sides of which embrace the sides of the axle members so as to cooperate with the guide members 3 to guide the axle. The sides of the U-shaped plate at the points where they embrace the axle are extended, as indicated at 11, and are secured to the axle member by one of the rivets 17 hereinafter referred to and also by an additional rivet 12, as shown in Fi 5.

Each of the s eeve bearings 13 for the vertical portion 14-. of the axle spindle 15 has an integrally formed hollow shank 16, substantially square in cross-section, which is placed in the adjacent end of the axle and rigidly connected therewith by rivets 17 which pass through the vertical webs of the two axle members. 8 so as to further stiffen the axle structure and provide for rigidly securing the bearing sleeve thereto. A sleeve 18 at the juncture of the vertical and horizontal portions of each spindle is keyed to the spindle by a pin, shown in dotted lines at 19 in Fig. 5, and this sleeve has oppositely projecting ears 20 to which are secured by rivets 21 the steering arm 22. The upper end of bearing sleeve 13 is closed by a cap 23 which is se-. cured to the upper end of the spindle by the pin 24 so as to turn therewith, the cap being provided with means in the usual way for insertion of lubricant. The sleeve 18 not only acts as a means for attachment of the steering arm but also serves to sup ort the bearing sleeve 13 and the weight 0 the vehicle im osed thereon through the axle.

From igs. 1, 2 and 5 it will be seen that the bearing sleeves 13 and the vertical portions of the axle spindles are inclined inwardly toward the bed from bottom to top. Further, it will be seen from Figs. 1 and 3 that each of the bearing sleeves and vertical portions of the axle spindles are inclined rearwardly from the bottom to the top. As a result of these inclinations, when the front wheels are turned, the inner wheel will lean outwardly, while the outer wheel will re main perpendicular. This is due to the fact that with the inner wheel the two inclinations coact together to tilt the horizontal portion of the spindle downwardly, while wlth the outer wheel the two inclinations offset each other to cause the horizontal portion of the spindle to remain horizontal. As a result of this arrangement the'inner wheel, in turning, will clear the guide pieces 3, and in this connection it should be explained that in practice it is the inner wheel only that needs to be tilted to avoid striking the guide pieces, hence this arrangement provides for the tilting of the inner wheel but not of the outer wheel.

A substantially til-shaped bolster 25 of an le iron has its horizontal and vertical webs riveted to the webs of one of the angle iron sills 2 by the rivets 26 and has its central portion resting upon the top of the central portion of the axle. Secured to the vertical web of the bolster by rivets 27 is a vertical web of a bent up plate 28, the horizontal web of which projects forwardly and is ofiset upwardly as indicated at 28. Secured to the forward side of the axle by rivets 10 is a U-shaped member 29. The horizontal webs of this U-shaped member receive a pivot bolt 30 the head 30' of which is disposed between the upper horizontalportion of'the member 29 and the ofiset portion 28; the bolt having an extension 30" which extends loosely throu h the a erture in the part 28, thus holdm the olster against endwise movement on t e axle and also holding the bolster in alignment with the axle. Pivoted on this bolt is a sleeve 31 provided with a renewable bushing 32", which acts as a spacer. The sleeve 31 has on its forward side an integrally-formed transversely-extending boss 31' provided with a transverselyarranged opening 32 to receive a bolt 33 upon which is secured as rigidly as possible the vertical webs of a pair-0f angle iron draft members 34 which extend forwardly and point slightly back of the U-shaped draft members are apertured to receive a pin 37, one end of which has a head 38 and the other adapted to receive a cotter pin 39. The tongue 40 is provided with wear plates 45 at its sides and is inserted'between the members 34 and is apertured to receive the pin 37 so that the tongue is connected to the members 34 on a horizontal pivot, the members 34 being in turn rigidly connected to the sleeve 31, which sleeve is connected to the axle and bolster on a vertical pivot. This arrangement permits the tongue to swing vertically on the pin 37 and laterally by reason of the pivot 30.

- The steering arms 22 are connected with the draft members 34 through the links 41. The outer end of each of these links isformed with an eye to receive a bushing 42 (Fig. 3) throughwhich extends a bolt 43 carried by the arm 22, the free end of the arm being bent back in parallel spaced relation with the main portion thereol so as tdreceive the end of the link 41. The inner end of each of the links 41 is formed with an eye 44 to receive a hardened pin 46 carried by a bracket 47 which is riveted to the horizontal plates of the draft appliance members 34 as shown in Fi 9. The upper end of the pin has a reduce neck 46 which passes through an aperture in the bracket and is riveted down as shown in Fig. 9, the pin being renewable as occasion demands. The bracket 47 has end extensions 47, curved slightly in a rearward direction, which extensions act as stops which contact with the axle member 8 to prevent turning too close.

In Fig. 10 the axle guide members are in the form of two parallel spaced a art angle bars 48 braced at their upper ends y a late 49 and connected at their lower ends y a cross-bar 50, the bars and plate being riveted or otherwise secured to the beam 1. In Fig. 11 are shown the same parallel, spaced-apart angle members 48 connected at their lower ends by the cross-bar 50, but instead of the plate 49 they are braced by brace rods 51 connected respectively to the guide members 48 to the beam 1 and an additional cross-bar 52 being provided. In Fi 12 the guide members are in the form 0 an inverted U- shaped structure 53, which structure has its 56 braces the upper ends of the members. In Fig. 16 there is shown a modification in the axle construction in which two channels 57 are employed instead of the angle irons 8 shown in Fig. 4;. The filler member indicated at 58 is also somewhat modified over the member 9 shown in Fig. 4. In Figs. 14 and 15 there is shown the same form of guide members as illustrated in F ig. 3, but the portions 3 and 3 of the rear guide is shown reinforced with an additional angle iron 3 placed on the rear side thereof with the plate 6 between the same.

By the arrangement of axle guides described, in which a pair of guides is provided for each end of the axle, the upper portions of which are rigidly connected to the longitudinal metal beams of the body as well as to the body, and which have their lower portions firmly braced by the upper cross plate 6 and lower tie rod 7, it will be seen that the axle will not only be guided in its up and down movements and be limited in such movements, but that provision is made for holding the axle in position when the groundwheels swing partly under the bed in turning; this arrangement furnishing axle guides which will resist all shocks and jars which are brought upon the axle due to uneven travel of the machine and also to shocks which are brought upon the axle when the wheels strike boulders or other obstructions.

Having thus described my invention, I claim:

In a machine of the character described, a body having a fixed bolster, a metal axle supporting the central portion of said bolster for limited rocking movement, guides embracing the ends of the axle, there being one pair of said guides at each side of the machine and comprising metal strips bent to form a pair of spaced parallel lower portions, divergent middle portions, and upper portions, the upper portions being rigidly secured to the sides of the body, a bar connecting the lower ends of the parallel portions close to the under side of the axle to limit rocking movement of the axle, a plate rigidly connecting the divergent portions to stiffen and brace the guides and hold them in proper spacing to each other, and a connection between the axle and the central portion of the bloster which prevents lateral movement of the bolster with respect to the axle but permits limited rocking movement of the bolster on the axle.

In testimony whereof, I have hereunto set my hand this 11th day of March, 1923.

HENRY SYNCK.
