Application October 6, 1943, Serial No. 505,139

(Cl. 28B- 61) 1 Claim.

My invention has for its primary object to provide a simple, low cost skid-way dolly equipment which can be readily adjusted in assemblage to meet all conditions for shifting heavy articles, such as machines, from place to place in shops, warehouses and the like, whereby material reduction of man power in such operations is made, and also to eliminate prevailing personal injury cases. f

Another object of my invention is to provide a dolly unit embodying a skeleton frame with sets of rollers mounted upon xed shafts supported on roller bearing spindles having loosely mounted keeper discs interposed between the roller` spindles and juxta-posed walls of the frame, whereby friction is reduced between the rollers and frame and Said discs at the same time perform their keeper function.

With the above and other minor objects in view, the invention consists in certain peculiarim ties of construction and combination of parts as will be fully set forth with reference to the accompanying drawing and subsequently claimed.

in the drawing:

Figure 1 represents a diagrammatic, plan View of a skid-way dolly equipment embodying the features of my invention.

Figure 2 is an enlarged, plan view of a dolly unit in accordance with my invention with parts thereof broken away and in section as indicated by line 2--2 of Figure 3.

Figure 3 is a vertical, sectional. view of the dolly, the same being indicated, by line 3--3 of Figure 2.

Referring by characters to the drawing, I-I indicates side plates, and 2-2 end plates of a rectangular frame. The end plates of the frame are reinforced and connected by a vertically disposedcentral division plate 3, which plate is also connected to the side plates I by a transversely disposed reinforcing plate 4.

The upper edges of the frame plates are connected by transversely positioned end back panels 5-5 and a central back panel B spaced from the panels 5, as clearly indicated by Figures 2 and 3.

The frame is preferably fabricated from steel plates, which plates are secured by welding in the usual manner. It being understood that said frame is designed to resist very heavy load tonnage.

The side plates I are apertured and have brazed thereabout collars 'I-l for the reception of transversely disposed shafts 8-8, which shafts are xed against rotation by locking pins I which pass through the collars and edges of the shafts.

end thrust anti-friction bearings to effectuallyL eliminate heavy load strain in all directions, that might tend to spread the .frame andjam the as sociated parts, it being understood that the spindle ends are iiush with the ends of the roller and abut the anti-friction discs.

In order to provide an adequate lubricating system for each roller, the ends of the shafts v8 are centrally bored for lubricating channels I2, which channels have branches communicating with the bore of the roller and feed channels I2 that communicate with lubricating nipples I3 that are in threaded union with suitably aligned apertures in the frame collars 1. Hence, each roller has a denite means of lubrication, which is quite essential in a heavy duty dolly of this type.

The back panels of each dolly unit are also provided with a plurality of calks I4 extending from the spaced panels for engagement with skid-way timbers I5--I5 as indicated in the diagrammatic View of Figure 1.

Having thus fully `describeda dolly unit, in their operation, as indicated in Figure 1 the timbers I5 are longitudinallyv positioned upon the back panels of a pair of dollys A--A and a ma'- chine or other article, indicated by the dotted lines B, which has previously been jacked up, is positioned over the dollys with the center gravity of said. machine approximately centrally disposed with relation to said pair of dollys, whereby the said machine `is properly balanced. Thereafter, the jacks supporting the machine are removed and its Weight is supported by the wooden skid-ways I5. It being understood that the tonnage of machines is such that it will cause the timbers to be embedded into the cleats, whereby rigidity, as to the position of said timbers with relation to the dollys, is insured. Thereafter the machines, by manual power, can be readily rolled from place to place upon its supports and in actual practice over a periodA of months, this equipment has been satisfactorily used in large plants upon all types of hard floors or pavements, whereby the usual rollers used for this general purpose are dispensed with and thus a saving of time is had and accidents, due to positioning the rollers, are avoided. y

It is obvious thatthe timbers and the associated dolly units can be positioned indefinitely, as to Width, with relation tov each other and also lengthwise, It is also apparent that the rollers of the dollys may be angularly disposed with reference to each other, whereby the load will more readily be moved in an arc of a circle.

What. I, claim as new is:v

A dolly comprising a, skeleton frame including vertically disposed apertured side plates, end plates connecting the same, a vertically disposed central division plate connecting the end plates having apertures aligned with the side plate apertures, avertically disposed reinforcing cross plate connecting the side plates and division plate, forming :four skeleton cages, top panels extending inwardly from the end plates, connecting thev side plates and division plate forming angle-iron reinforcements at the ends of the frame, a transverse centrally disposed panel extending in both directions from the cross plate and connecting the side plates `to -form a T shaped reinforcement Tor the frame, pairs of shafts extending through the division plate and side plate apertures, and pairs of rollers mounted upon each shaft, the same being housed Within the frame cages. l
