UTILITY TRUCK DOLLY Filed April 18, 1955 Patented Apr. 30, 1935 UNITED STATES PATET QFFIQE 1 Claim.
This invention relates to that type of truck or dolly, for conveniently supporting a piece of heavy furniture, electric refrigerators, or any kind of commodity, in such manner that it may be readily shoved about manually upon the show-room floor, or elsewhere. Heretofore these trucks have been made of metal or wood. The metal trucks are heavy and expensive, and the wood trucks are either too heavy or, when made light enough for convenience in moving them about, are too frail for long usage. It is the object of my invention to so construct this truck or dolly that it will not only be inexpensive in construction but will be light in weight and be especially durable in that it will not wrack or loosen in the joints with extensive use and therefore become useless, as more fully hereinafter set forth.
In the drawing annexed, Fig. l is a perspective view of my improved truck;
Fig. 2 is a bottom View thereof;
Fig. 3 is a sectional view taken through the central tightening device;
Fig. 4 is a detail perspective view of one of the stretched wire braces; and
Fig. 5 is a detail View of one of the hook bolts.
Referring to the drawing by reference characters, 5 designates the usual side bars of the truck connected together by the usual top bars 6 and at their corners by the usual short posts l, these latter being provided with the usual casters.
In the inner corner of each of the posts I is fastened a hook-bolt 8 which projects inwardly, and in two of the side bars or rails '5 is anchored a pair of similar hooks 9. Stretched between the aforesaid hooks is a flexible wire structure arranged as follows: To each pair of opposite hooks 9 is attached the extremities of a wire which forms two transverse legs it and two diagonal legs H, making in all four diagonal legs II and four transverse legs ill, the latter being arranged parallel to each other at opposite sides of a center line drawn through the truck frame.
From each hook 9 the wire extends inwardly, around an arcuate metal channel l2, thence diagonally to the opposite hook 8, around which it is looped, thence back to the channel-iron l2, thence to the companion corner hook 8, around which it is also looped, thence back and around the channel-iron, and thence to the opposite hook 9, to which it is anchored by a loop or ring. At the point where the wires contact with the channel-iron l2 they lie in the channel thereof. The two channel-irons l2 are connected by a central, threaded rod l3 which lies at right angles to the legs H] of the bracing Wires and whose ends extend through holes M in the channel-iron. On the ends of the rod l3 are threaded nuts l5 which manner.
when screwed up on the bolt abut against the concave sides of the channel-irons and draw the channel-irons toward the center of the truck i. e., toward each other. Suitable split spring washers it are desirably employed between the nuts and the concave sides of the channel-irons to thereby tend to lock the nuts in their tightened positions.
It will be observed from this wire structure that the tightening of the nuts draws all the legs iii and I I taut, thereby bracing the structure in all directions and rendering the usual heavy braces unnecessary. Should the members of the truck frame loosen up from use they may be readily tightened up again by means of the nuts i5. It will be understood, of course, that during the tightening operation the wires are free to slide in the arcuate channel-irons, so that all parts of the wire bracing structure will be under the same tension. The object of channeling the wires i2 is to prevent the wire slipping off the side edges thereof. It is obvious that other forms of screw-threaded tightening devices may be employed without departing from my invention.
25 It is desirable that the hook-bolt 8 shall be anchored in the corner post in a substantial One good way of doing this is to em-= ploy a threaded sleeve i8 which is housed in a hole in the post and couples the inner end of hook-bolt 8 to an extension bolt H which extends diagonally through the post to the exterior corner thereof, where it is provided with an angular head adapted to fit around and embrace the corner of the post. In this way the bolt will be substantially anchored in the post and the pull on the inner hooked end of the bolt will draw the post inwardly and thus contribute very materially to the rigidity of the frame, which rigidity is effective in preventing the casters tearing out or loosening from the posts.
I claim? In a truck of the class described, a frame and a bracing means for said frame embodying two wire lengths. one arranged at each side of the center of said frame and each extending from one side Wall to the center of the frame, thence to an opposite corner of the frame, thence by a loop back to the center of the frame, thence by a loop to an opposite corner of the frame and thence back to the center of the frame and thence to the opposite side wall of the frame, and central means connecting the two wire structures thus formed, this connecting means embodying devices for tightening said wires simultaneously and uniformly.
JOHN HENRY DE BOER.
