TIP-WAGON MECHANISM.

SPECIFICATION forming part of Letters Patent No. 746,541, dated December 8, 1903.

Application filed August 3, 1903- Serial No. 168,057. (No model.)

To all whom it may concern:

Be it known that I, ALEXANDER MANSFIELD, a subject of the King of Great Britain and Ireland, residing at Brunswick'street, North Fitzroy, in the State of Victoria, Commonwealth of Australia, have invented certain new and usefullmprovements in Tip-Wagon Mechanism; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of'this invention is to provide improvements in tipping mechanism whereby the loaded vessel may be raised obliquely on either side of its support and tipped while be-.,

ing elevated to discharge the contents into or upon any suitable receptacle, traveling belt, or receiver on either side of its normal position.

The invention is more particularly applicable to wagons, in which connection I will describe the same; but it is obvious that it may well be adapted for cars and analogous means of transportation.

To more fully understand the same, reference is bad to the accompanying drawings, in which like characters designate like parts in the several views, and in which I Figure 1 represents an end elevation of a part of a wagon containing my improvements;

Fig. 2, a reversed side elevation of the tipping mechanism and its support looking from the inside; Fig. 3, a detail fragmentary plan view, and Fig. 4 a detail view of the trunnionbearing and slide.

As each end of thewagon is provided with similar mechanism, I will for brevity only describe the mechanism at one end thereof.

a indicates the tilting receptacle, 1) a bracket on the end thereof, and c a trunnion-bearing on said bracket.

0c is a suitable fixed frame having the downwardly-converging top faces 0 and the centralcurved cut-awayclearance-spacey. Supported by this fixed frame as is an adjustable frame comprising the rounded baseportion 1 h, the arms h, and the upper cross-piece h suitably bolted to the arms h. These arms h are provided at their upper ends with cars from its seat.

713, slotted, as at u, to aline when in position with corresponding slots 11. in the frame 00.

The outer face of the arms h and the base portion h are flanged, as at w, to form the channel h therearound, adaptedv to seat on the inclined faces 0 of the frame at, and are recessed at h h to engage the pins 8 s on the frame 00, respectively, when the adjustable frame is shifted from one side to the other and hold the base portion h against rising The other end of the adjustable frame is held down on its seat by the pins 15, passing through the slots 11. u.

e is a slide having its side faces channeled, as at f, adapted to engage the inner faces g of the arms h and be guided thereby longitudinally of the adjustable frame.

The inner face of this slide-block e is provided with an elongated slot d, forming a ournal for the trunnion pin or bearing a, and

is internally screw-threaded centrally to receive an elongated screw '5, rotatably journaled at one end in the cross-piece b and carrying at its other end the fixed bevel-gear j. Suitably journaled in the adjustable frame is the gear-wheel l, and alongside the same is located the bevel-geark, meshing with the bevel-gear j. p

m is a pinion meshing with a large gearwheel Z, the shaft of which is provided with a crank it or other suitable driving means.

'1" represents bearers provided with the abutment-surfaces g, by means of which the loaded receptacle is tilted and rests at different points on the curved surface as the receptacle at is being elevated obliquely, the abutments q being located sufficiently inside-the plane 5 (parallel to screw 6) and acting as an obstruction to the rise of the interposed receptacle on that plane. As the raising proceeds the angular displacement of the recepstops prevent displacement of the body during haulage. These are not shown or claimed.

In operating this invention power applied to drive pinion m is multiplied by spur-wheel Z and conveyed by bevel-wheels 703' (where the power is again multiplied when desired) to screw 1, which is thus turned in its bearings, by which it is fixed in frame it, the screw thereby leading along its length slide-block e, (a worm through which the screw engages,) having trunnion-bearing d. The operator at one end may work faster than that at the other, or one may work both body ends alternately, the trunnion-bearing (1 being made large enough to permit of one end of the body standing higher than the other. Means (not shown or claimed) maybe provided to secure body a temporarily at any desired inclination, and abutments q may be adjustable or movable instead of fixed. Any suitable means are provided to temporarily lock frame It in its inclined position on either of the converging faces 0. Preferably there are at the base and at each side projecting flanges w, between which the sides 0 and frame w fit. Also stops 8 s and slots to are provided at each side. Stops s s serve to restrain the lower end it of the adjustable frame from being lifted out upward, and when any suitable pins are passed through slots it into frame a: they prevent that end of the frame moving.

It will be observed that apertures u, u, and d are elongated and that in Fig. 1 the upper ends of the slots are engaged by the pin 2i and trunnion c,respectively,and in Fig.2 thelower ends. This is to allow the frameh to be lifted a little or made to slide upward (by a few turns of the handle n) off its seat on frame x at such times as said frame It is to be swung on its pivot 0. Thus friction is reduced. The frame m is cut away at y to allow this clearance. When, however, the handle is turned for the raising of the body, the first effect is to lower frame It till it sits solidly on frame w. This construction limits the strain of the body a on the slide-blocks to such times as the raising is proceeding. The angle of the slot and the pitch of the screw within it, the sizes and number of teeth in the respective gear-wheels, and like details will depend upon local circumstances.

What I claim as my invention, anddesire to secure by Letters Patent of the United States, is 1. In unloading mechanism, the combination with the receptacle and a suitable support therefor, of means for obliquely elevating said receptacle, and means for tipping the receptacle, while being elevated,-transversely of said support and supporting the same while being elevated and tipped, comprising curved abutments adapted to engage the lower side faces of said receptacle.
