WILLIAM MCINTOSH, OF IRON RIVER, WISCONSIN.

RUNNING-GEAR FOR WAGONS.

Specification of Letters Patent.

Patented Feb. 12, 1907.

Application led April 21, 1904. Serial No. 204,147.

To @ZZ whom, t may concern:

Be it known that I, WILLIAM MoINTosH, a citizen of the United States, residing at Iron River, in the county of Bayfield and State of lVisconsin, have invented a new and useful Running-Gear for Wagons, of which the following is a speciiication.

rIhis invention relates to a running-gear for farm-wagons or other comparatively heavy draft-vehicles.

The especial objects of this invention are to provide a strong, simple, and efficient running-gear for vehicles of the class referred to which will have suficient flexibility so that it will not be strained or weakened by use on comparatively uneven highways or other surfaces, to provideV for securing equal distributions of the draft or hauling strains, and to provide a frontaxle construction permitting the vehicle to make sharp turns, while the front wheels will be maintained in parallelism in all positions.

In the accompanying three sheets of drawings, Figure 1 is a plan view of a runninggear constructed according to this invention, the position of the wagonebody being indicated by dotted lines. Fig. 2 is a rear iiew of the same, Fig. 3 is a sectional view taken on the line 3 3 of Fig. 1. Fig. 4 is a detail plan view of part of the front-axle construction. Fig. 5 is a partial rear view of the front-axle construction, partly in section. Fig. 6 is a detail view of one of the top bearing-plates to which one of the axle-blocks is pivoted, and Fig. 7 is a detail view showing the adjustable connection between the rearaxle construction and the center pole or reach.

In United States Letters Patent No. 707,618, dated August 26, 1902, I have shown, described, and claimed a dumpingwagon in which the wagonbody takes the l Referring to the accompanying drawings and in detail, the rear-axle construction is most clearly illustrated in Figs. 1 and 2.

As shown in these figures 10 designates the rear axle, which is provided at its ends with metallic end pieces 1 1 extending from which are the studs upon which the wheels WV are mounted. Resting upon the rear axle 10 are hounds 12 and a spool-shaped center bearing 13 for adjustably receiving the rear end of the reach or center pole 23. The hounds 12 and center bearings 13 are clamped in place by a bolster 14, which is fastened rigidly in place by bolts 15. The bolster 14 is provided with side posts or pieces for holding the wagon-body rigidly in position thereon. The frontaxle construction is most clearly illustrated in Figs. 1 and 3.

As shown in Fig. 3, the front-axle construction comprises a bolster 18, carrying a metallic top plate 19. Resting upon the bolster 18 is a rocking bolster 20, which is pivoted on a horizontal bolt 21, carried by yokes 22, extending up from the bolster 18. The rocking bolster 20 is provided with side posts for connecting the same to the front end of a wagon-body.

I consider it a feature of advantage to use a rocking bolster in the forward-axle con` struction rather than in the rear-axle construction, as shown in my prior patent before referred to, because whenever the front axle is sharply tipped or inclined with respect to the wagon-body, which happens, for example, when one of the front wheels runs into gulley or deep rut, the weight of the wagon-body will not rest upon the wheel which has sunk into the depression or gulley.

In ordinary usage the front wheels of avehicle are more liable to be driven into gulleys or deep ruts than the rear wheels, and inasmuch as the use of a rocking bolster in the front axle construction will prevent the weight from resting on the sunkendown front wheel I have found that a wagon employing a rocking bolster in the front-axle construction is less liable to become stuck and can be hauled with less exertion than in constructions where the ro cking bolster forms part of the rear-axle construction. This advantage is secured Without lessening the advantages due to the fact that the hont and IOO rear bolsters are always parallel with eachv other and also that the iront bolster is parallel with the front axle.

Extending back' from the bolster 18 and connected rigidly therewith are the, hounds 24 and a reach or center pole 23.`

As shown in Fig. 1, the hounds 24 are rigidly connected to the reach or center pole 23y by the strips 26. The rear end of the center pole 23 is roundand extends loosely throughv thebearing-plates 16, carriedv by the/rear hounds v12 and the center bearing 13 inthe rearaxle construction.

The running-gearis adapted 'for usein connection withv wagon-l bodies of different lengths by means of a pin which may be put into .any one of a number of sockets in the reach 4or center pole 23.

Connected with lthe ends of kthefrearhounds 12 are draftfrodsli, and connected with the4 rear ends ofthe Jronthound-s 24 are draftro ds;27,. Bolted onto the under side of the bolster 18 are blocks or separating-pieces29. Carried by the pieces 29 isa metal plate 3Q. Secured on the ends of the bolster 18 are top bearingfplates 32, and secured on theendso'i the metal plate 30y are bottom bearingeplates 33. Pivotally mounted between-the plates 32and 33 are axle.-r blocks 34, whichcarry the stub-axleson which the front wheels arel journaled.

The connectionsy yfor turning the front wheels from thetwagon-pole are` most clearly illustrated in Figs. 1 and 41.. As shown in these figures, each Lof the aXle-blocksre is provided with an outwardly-inclined arm 35., Pivotally connecting the inclined arms 35 with the bolt 37, 'mounted in the yoke which carries thewagon-tongue, is a link36, which is yalways.parallel with the central party of the front-axle constructionthat is to say, when thenparts are in normal position thepivotal connections between the linkl 36 and the ,out-,1 wardly-inclined arms 35 and the yoke 31 are directly opposite the pivots o'l` they axle-blocks and the yoke 31, respectively. The motion,

of the `parallel link 36 is the same as that of.

the-movablegmember of a parallel ruler, and

I regard this as a feature of advantage, becauseby means of this constructionthe front wheels willl bemaintained in parallelism in all positions, Pivotallymounted in the yoke .31 isthe ordinary wagon-tongue 320.

In f theuse of a completed wagon constructed according to this invention the center. pole or reach being rigid with the Jfront-axle,construction and having ya loose bearing inthe rear-axle construction willgive suthcientilexibility so that the iunningf-gear will;` notk be strained-,`no matter how uneven the ,road or surface; up on which the team ,isl d uren..

The front-axle construction is such that short turns may be made. If an obstacle is encountered, the -wheels may be turned to leave it without backing. The pull of the load tends. to centralize the pole, and at the same time the pole does not have a tendency to whip the team on rough roads. I/Vhen one wheel isv in a hole, the rocking bolster car- 7o riesthe weight onto the wheel which is out or' the hole, leaving less weight on the one in the hole.

I amaware that. changes may be madein the constructiongoi.- my .running gear. afer 175 wagonsA by thosevwho, are skilled in the art; and that certain features of my wagon can .be used in other connectionswithout` depart ing from the scope ofmyinvention aser.
