- to which it appertains tomake and use the same.

My invention relates to trucks, and more particularly to that class of trucks adapted for moving houses or other large objects.

The object of my invention is to provide a truck for moving houses which will necessitate the house being raised the least possible distance from the ground during movement,

thereby reducing to a minimum the cost of moving and also the possibility of injury to the walls of the house due to twisting.

Another object is to provide a truck having wheels which may be adjusted at any angle to the path of the load, without changing the bolsters or raisingthe building.

A still further object is to provide supportingwhcels for the truck arranged in pairs and connections between the pairs of wheels, whereby each pair is allowed to rock or travel in any plane entirely independent of the other wheels.

In the accompanying drawings, Figure 1 is a plan view of a frame supported upon three trucks. Fig. 2 is a plan view of a frame supported upon six trucks arranged in pairs so as to support an extremely heavy load.

Fig. 3 is a sectional view on the line 3-3 of Fig. 2, showing the connecting beam between the front pair of trucks. Fig. 4 is a sectional view on the line 4.4 of Fig. 2, showing the connecting beam between the rear pairs of trucks. Fig. 5 is a sectional view on the line 5-5 of Fig. 1, showing the extension bolster disposed between the wheels of the front truck. the line 66 of Fig. 1, showing the extension bolsterdisposedbetweenthe wheel's of the rear trucks. Fig.7 is a perspective view of one of the bolsters. Fig. 8 is a sectional view on the line 8-8 of Fig. 1.

Referring to the drawings, in which similar reference characters denote correspond ing parts throughout the several views, 1 represents the wheels which are arranged in pairs and mounted in spaced relation upon short shafts :2, said wheels having disposed Fig. 6 is a sectional View on.

therehehveen bolsters- 3 havingv a bore l in the lower portion thereof through which extends the shaft 2. The upper portions of the bolsters are provided with slots 5 which extend from the upper surface thereof and taper downwardly, terminating a short distance above the lower bore 4.

Each truck is composed of two' pairs of wheels, the pairs of wheels being arranged to travel rearwardly of one another or side by side, and are connected in either'arrangement by means of connecting beams 6. The ends of the beams are bent downwardly to provide fingers 7 which are loosely mounted within the slots 5 of the bolsters 3, while the central portion of the beam is depressed as shown at 8. The bottom portion 9 of the depressed portion 8 is provided with laterally projecting lugs 10, for a purpose which will hereinafter be made more clearly apparent.

The frame for supporting the object to be moved is composed of longitudinal beams 11, and front. and

rear cross beams

12 and 13 respectively, said beams being connected by substantially Z-shaped sections of metal 14. Referring to Fig. 1, wherein is disclosed three trucks for supporting the frame, it will be noted that the front truck has the wheels thereof arranged longitudinally of the frame, and the connecting beam 6 which connects saidtwheels is disposed under the front cross beam 12 for supporting the front portion of the frame, while the wheels of the rear trucks are arranged transversely of the frame and are connected by the connecting. beam 6, the central depressed portion of the latter receiving and supporting the longitudinal beams 11 of the frame. To allow pivotal movement of the trucks beneath the cross beams l2 and 13, I I

secure to said beams, directly above the horizontal portion 9 of the central depressed portion 8 of each connectingbeam, a plate 15 having an openin therein to receive the stud 16 of a cap 17, t e latter having a semi circular depression in its under surface within which is positioned the aforementioned lugs 10.- For insuring a rigid connection between the cap 17 and the lugs 10, straps 18 are positioned around the under faces of the lugs 10, and secured to the under surface of the caps 17.

Each shaft 2 carrying the wheels 1 is rovided with a pair of straps 19, to which is secured'the draft and steering pole 20. The

draft poles 20 of the rear trucks are secured by chains 21" to the rear cross beam 13in order that the said rear trucks will be permanently adjusted to pursue a path longitudinal to the frame, Whereas the draft pole 20 of the forward truck is adapted to re- 'ceive a suitable propelling means. I

In Fig. 2 is disclosed a slightly different arrangement of the trucks, and wherein six trucks are employed instead of three, as is Y the number employed in Fig. 1. The trucks 'in Fig. 2 are arranged in pairs and are connected by cross beams 22, having arranged centrally thereon, the laterally extending lugs 10, the same as those employed upon connecting beams 6. The upper surface of the beams 22 carries the frame composed of the longitudinal and cross beams, while the ends of said beams are provided with apertured plates 15, as shown at 23, to receive the stud 16 carried by the cap 17 the latter being secured to the laterally extending where an extremely heavy house or other trucks may be employed by the introduction 'of the beams 22, as shown in Fig. 2. It will be further seen that by the improved supports for the frame, the latter is supported only a very short distance above the, ground, thus enabling the operators to readily position the heavy object to be moved thereon.

What I claim is p A truck comprising pairs of front and rear wheels, a shaft for each pair of wheels, bolsters positioned on said shafts between said wheels, seats formed in said bolsters having the upper portions thereof elongated on a line longitudinal of the shaft and tapered downwardly, a connecting beam having the opposite ends turned downwardly and mounted within said seats and having the central portion depressed, lugs extending laterally from the depressed portion of said connecting beam, a cap disposed over said lugs and having an upstanding stud, and straps connecting saidcap with said lugs.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
