SPECIFICATION forming part of Letters Patent No. 534,1 13, dated February 12, 1 895.

' Application filed April 23, 1824. Serial No; 508,665. (No model.)

To all whom it mctyconcern: v

Be it known that I, HUGH LIND, a citizen of the United States, residing at Whitewater, in the county of Mesacand State of Colorado, have invented a new and Improved Truck, of whichthe following is a specification.

My invention relates to improvements in trucks, and has for its object to provide a truck for moving heavy objects, suchas pianos, lumber, heavy castings, stone, or other similar materials, which shall be durable, simple in operation and construction, and which,

when in use, will be well balanced and therefore can be moved withgreater case.

With these and other objects in view, tn'y invention consists inthe improved construction and combination of parts, as more fully described and pointed out in the claims.

In the drawingsz-Figurel is a perspective view of my improved truck. Fig. 2 is a detail perspective of the clamping ring, and Fig. 3 is a sectional view, showing the means for clamping the ring in; position.

Similar numerals of reference indicate similar parts in all of the figures of the drawings. Referring to the drawings, 1 designates the frame of the truck, consisting of two upright pieces 2 2, connected at their top by a hori-' zontal piece 3, which is made square, except a short distance at each end, as shown at 4. The purpose of providing this form will be hereinafter shown. The upright posts are conne'cted at their lower ends by a brace 5, which extends forward and upward, and has at its center. a fastening device 6 to secure the handle 7. The said handle has at its forward end,

1 a cross piece, of size sufficient to enable two wardly, and then pointed, so as to secure a firm hold on the platform 11, upon which the piano or other load, is to be carried. These rods, a short distance below the horizontal piece 3 are connected together in pairs, by jointed rods 12, thereby forming a hinge joint for the rods, and enabling them to be placed at different distances, and still be firmly braced, which is necessary in carrying a heavy Fitted to the horizontal cross piece 3, equidistant from its center, are two collars 13,

eachcollar having on its sides (as clearly shown in Fig. 3) an opening 14:, to receive a clamping bolt 15. This bolt has an opening 17, la'rge enough to allow of the passage of one of the sliding arms of the clamping ring 18, and has a slot 19, extending from its outer end to said opening.

20 designates a nut havinga threaded opening adapted to fit said bolt, and cause the same, when the nut is screwed on to the bolt,

. to clamp the sliding arm of the clamping ring 18, and thereby hold it from moving out of position.

18 designates a clamping ring, made ofasingle rod, and having formed at its lower end, a rectangular opening 21, through which pass rods 10. At the rear of said opening the rod extends outwardly and then inwardly, thereby forming a stop to keep the clamping ring from passing too great a distance through the clamping bolt, and then extends rearward and upright, at an angle of about forty-five degrees, to form sliding arms 22, where the two ends of the rod are welded together.

Located at the top of the handle, at a suitable'distance from the horizontal piece 3, is

a bifurcated upright 23, in which is pivoted a lever 24:. This lever at one end is rounded to form a handle, and at the other end, ex tending from each side, are two yoke pieces, adapted to loosely fit the top cross bar of the clamping ring. Between the forward end and the pivot point of the lever, the lever is cut away to form a lockto fit the notches of the upright rodS.

25 designates the wheels of the truck, which hang on axles 26, secured to the upright pieces 2.

The operation of the truck is-as follows: When it is desired to move large pieces of furniture, heavy castings, lumber, 850., the platform is removed from the framework and allowed to rest on the ground, 850., near the article to be moved. The article is then placed on the platform, and the truck backed up to the platform, in such position that when the truck is tilted, t'. e:the handle 7 raised the rods 10 will have their lower ends resting on the ground, it being obvious that the handle 2t will be in its raised position. The rounded lower ends of the rods 10 are then inserted beneath the platform and the handle 24 pressed downward and locked in the notches 9 of rod 8. This movement of the handle serves to raise the clamping ring 18, causing its lower end to press inwardly on the rods 10, and thereby exerting a pull on said rods, which causes the lower ends to be moved upward and pressed into the underneath side of said platform, and become securely fastened therein. The thumb nuts 20 are then tightened, thereby holding the clamping rings from movement, after which the handle 7, is lowered causing the platform to be lifted from the ground, and by reason of its weight, be caused to swing and become balanced on said horizontal piece 3. To re move the load, the above operation is reversed.

It will be seen, by referring to the drawings, that the peculiar curvature of the handle 7, below the brace 5, forms a bearing point, should it be desired to stop the truck and leave it without resting the platform on the ground. When this is done, the upright pieces 2, 2, will be inclined at an angle toward the handle, and thereby cause the center of gravity of the platform and its contents, to fall within the wheels and the handle and therefore prevent the truck from tilting.

It will be obvious that by this construction a truck will be formed in which the load to be carried, will be balanced at all times, thereby compelling the person drawing the truck to carry a minimum amount of weight. It will be also obvious that the manner of loading and unloading presents a minimum amount of heavy lifting, as the power to lift is reduced owing to the length of the handle 7.

Changes in the form, proportion and other minor details of construction may be resorted to without departing from the principle, or

sacrificing any of the advantages of this invention.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A truck comprising in its construction a yoke frame consisting of two upright pieces connected at their top by a horizontal piece and at their bottom by a forwardly extending brace; wheels attached to said yoke frame; a handle connected to said brace and said horizontal piece; rods hingedly connected in pairs depending from said horizontal piece; a platform adapted to be suspended on said rods; and means for locking said platform on said rods, substantially as described.

2. A truck comprisingin its construction a yoke frame, consisting of two upright pieces connected at their top by a horizontal piece, and at their bottom by a forwardly extending brace, said horizontal piece being provided with bearing surfaces at each end; a handle connected to said brace and to said horizontal piece, wheels attached to said yoke frame; rods hingedly connected togetherin pairs, depending from said bearing surfaces of said horizontal piece, said rods having their lower ends bent upward and pointed; a platform adapted to be suspended on said rods; a lever attached to said handle to raise and lower clamping rings; collars on said horizontal piece, having attached thereto, bifurcated bolts through which pass a clamping ring, said bolts being adapted to firmly clasp said clamping ring; a clamping ring adapted to embrace each series of rods, and also adapted to form a connecting link between the said rods and said lever, for the purpose of securing said platform on said rods, substantially as described.

In testimony that the foregoing is my specification I have hereunto affixed my signature in the presence of two witnesses.

HUGH LIND.
