Specification of Letters Patent. Patented Aug. 23, 1910.

Application filed T-CTUi'cl H3, 1811. Se ial No. 548,936.

To all whom it may concern:

Be it known that I, MICHAEL KRAESKI, a citizen of the United States, residing in the county of Howard and State of Maryland, have invented certain new and useful Improvements in Wagons, of which the following is a specification.

My invention relates to wagons such as are usually made without springs, as farm wagons and other wagons of similar character.

The invention pertains more particularly to the running gear, and consists in the fea tures of improvement hereinafter described and more particularly pointed out in the claims annexed to this specification.

While retaining the general characteristics of approved constructions of running gear, I equip the same with supporting springs, interposed between the axle-trees and bolsters, at the same time bracing the axles against fore and aft displacement, and providing for rocking movement or wabble of the axle-trees relative to the bolsters; and I otherwise improve the construction by bracing or trussing the bolsters and more uniformly distributing the load thereupon, and supporting the load upon the axle-trees near the wheels so as to relieve strain at the center. I thus provide a practicable and eflicient spring farm wagon hav ing substantially the stability, strength, durability and other advantages resulting from approved constructions of modern running gears, thus avoiding unusual and impracticable constructions such as have in some instances heretofore been proposed for a spring farm wagon, and rendering my improvement applicable to standard makes of wagons.

Reference will now be made to the accompanying drawings, hereby made a part of this specification, in which I have illustrated a wagon running gear embodying my invention.

Figure 1 is a vertical cross-section through the front running gear, taken just in advance of and showing in elevation the front axle-tree and bolsters. This view includes only the central portion and one end of the axle-tree and bolsters, it being understood that the construction is duplicated at the end not shown. Fig. 1 is a cross section of the metal rest plate for the coupling pole. Fig. 2 is a vertical cross section of Fig. 1 taken on the line AA thereof. Fig. 3 is aview similar to Fig. 1 of the back running gear, showing the rear axle-tree and bolster in front elevation. Fig. 4 is a vertical cross section of Fig. 3, taken on the line 13-13 thereof. Fig. 5 is a perspective view of one of the spring casings.

Corresponding parts in the several views of the drawings are indicated by like reference symbols.

Referring to the front running gear (Figs. 1 and 2), 1 is the axle-tree, 2 the lower bolsterand 3 the upper bolster.

1 is one of the standards on the upper bolster.

5 is the coupling pole and 6 the king-bolt.

7 is a metal resting plate for the coupling pole and king-bolt.

8 is the swivel wear plate on the upper side of the bolster 2.

There are preferably two sets of hounds, 9 and 10. The outer ones, 10, correspond to the usual hounds of the front running gear but are spread farther apart than usual, being arranged under the end portions of the bolster 2. The inner hounds 9, placed about midway between the coupling pole and the outer hounds 10, extend forward from under the bolster 2; and the hounds 9 and 10 may converge and be directly joined together at the tongue (not shown) or they may be connected by a front cross-bar, both constructions being known in wagon manufacture.

9 and 10 are the bolts which fasten the hounds to the bolster 2. The bolts 9 connect the swivel wear plate 8 and resting plate 7 as shown in Fig. 1. The bolster 2 is also trussed by the rods 11,0ne in front and one behind-the bolster. These tie rods pass under the resting plate 7, the edges of which are turned at 11 (Fig. l) to keep the tie rods in place thereunder. The tie rods are secured at the ends of the bolster by small metal cross-bars 11 the screw-threaded ends of the tie rods being inserted through holes in said cross-bars and fastened by nuts. The ends of the bolster are notched to receive the cross-bars 11 12 is one of the curved metal slide bars which are carried by the outer hounds 10 and pass over the bolster 2, as usual in front running gears for wagons.

13 is the corresponding draft bar or brace secured to the under side of the hound and passing under the axle-tree. The front and rear ends of said slide bar and draft rod or under brace are connected to the hound by the same bolts 12*. The slide bar is also shown secured to the bolster 2 by the bolt 10*.

14 is the metal axle skein. The inner or socketed portion of the skein, which receives the end of the axle-tree, is embraced between the legs of a yoke-like metal spring case 15 which is shown enlarged in Fig. 5. The upper portion of this yoke is enlarged and cut away at 15 to receive the hound 10. At each side of the opening 15' the top of the yoke is formed with apertured lugs 15 by whichit is fastened to the under side of the "i hound by bolts 15. The feet of the yoke are formed with apertured lugs 15 by which it is secured to the under brace or draft iron 13 by the bolts 15 The cut or opening 15*, which fits the hound, is of a depth equal to about one-half the thickness of the hound.

a The yoke 15 contains a stout coiled spring 16 arrangedbetween the axle-tree and the hound. To keep the spring in place, annular seats 16 and 16 are fitted to its upper and lower ends; the spring seat 16 (which may be a washer having a rim or flange) being secured in place by the bolt 10, while the spring-seat 16 of like form, is held upon the skein by a bolt 16 which also serves for fastening the skein to the axle-tree.

The yoke 15 constitutes a rigid connection and brace between the hound 10 and the under draft iron 13, while the axle-tree is relatively movable and supports the wagon body l by the spring 16. To obtain the advantage of the yieldability of the spring, there must be no positive connection between the axletree and draft iron 13. For this reason the draft iron 13 is shown provided with an 5 opening 1'6 around the nut on the lower end the bolt 16. As the spring yields under the load thereon, the axle-tree moves relatively up and down in the yoke 15; to guide which the skein 14 is provided on its front and back sides with shoulders 14.

These shoulders 14 are made curved or convex, as shown, and the hole 1 in the axle for the king-bolt is formed in a similar manner,

whereby the axle-tree is permitted to rock or wabble on the king-bolt in going over uneven rods and thelike. v Referring now to the rear running gear (Figs. 3 and 4), 17 is the axle-tree and 18 a w the bolster, having the standard 19. The

Y rear hounds are indicated at 20, and,'like the,

front hounds 10, are spread farther apart than usual so as to bring the load nearer the wheels. The rear bolster 18 is trussed secured'to the ends of the bolster by the means already described, pass under a holder 22 for the coupling pole 5, the edges of which holder are turned to engage and keep the tie rods in'place in the same manner as the resting plate 7 of the front running gear. 23 is the brace rod. 24 is the draft rod or iron. 25 in Fig. 4 is the coupling pin, where the rear running gear is coupled to the pole 5. The supporting springs are applied to the back running gear in the same manner as in the front running gear, only the connections being slightly different to suit the back running gear construction. The same reference characters are therefor applied to the yoke 15 with its out 15 to fit the hound 20; the spring 16 and its seat rings 16 and 16 and the skein 14 with its rounded shoulders 14 to guide the yoke. The draft rod or iron 24 is secured to the feet 15 of the yoke by the bolts 15", and is formed with an opening around the nut on bolt 16 as in the front running gear construction. The bolster 18, hound 20, brace-rod 23 and upper spring seat 16 are joined by the bolt 18*; while the lugs 15 of the yoke are secured to the bolster by bolts 18 and 18, the latter being an extension of the strap iron 18 that goes over the standard 19.

As will of course be understood, the constructions shown in Figs. 1, 2 and in Figs. 3, 4 are duplicated at the other side of the wagon.

It will be seen from the foregoing that besides trussing the bolsters, I support the weight on the hounds 10 and 20 which rest on the springs 16 upon the axle-trees near the wheel-spindles, thus bringing the load more directly upon the wheels, and relieving the strain at the center of the bolsters and axles; and, while the wagon body is spring-supported upon the axles, the latter are well braced by the draft rods 13 and 24, thus preventing displacement; the axles being also allowed to rise more or less at either end or to rock at the center in going over ruts or on uneven roads. It will also be seen that the structure of the running gear conforms to approved farm wagon constructions.

I reserve the right to such modifications in details of construction and arrangement as may be made within the scope of my invention as set forth in the following claims.

I claim as my invention and desire to secure by Letters Patent:
