T e swing arms have longitudinal slots 23 which receive pins 24 projecting from the sides of the hopper.

A hook bar 25 hinged upon the hopper at 26 has a hooked end 27 which is passed over the journal spindle 15 of one of the cross bars to hold the hopper in horizontal position until it is desired to tip its load, when by releasing the hook the hopper may be tilted into the position shown in dotted lines Fig. 3 or the tilting of the hopper may be effected by rearward movement of the vehicle as hereinafter described.

Ropes 28 and 29 one upon each side of the apparatus are at their respective ends fastened to the axles of the rollers 8.

V The rope 28 passes around a guide sheave 30 and from thence is led beneath another guide sheave 31 to the barrel 32 of a winch which is fixed to the standards of the frame.

Rope 29 passes around guide sheave 4:8 and beneath guide sheave 49 to the winch barrel 32. Both ropes 28 and 29 being coiled around the winch barrel in the same direction. The guide sheave 48 is located beneath the runways 4a so as to be clear of the wheels of vehicle 14.

The winch is of ordinary construction having turning handles 33, gear wheels 34, hand brake 35 and ratchet wheel 36 engaged by a pawl 37.

Another rope 38 is secured at its end to the winch barrel 32 around which it is wound in opposite direction to ropes 28 and 29, it then passes beneath a guide sheave 39 around another guide sheave 40 and is connected to the axle of roller 8 upon the same side of the apparatus.

To prevent the side rods 11 from turning down beyond a certain limit when the striking bar is not in contact with the back of a vehicle, bearer brackets 42 are fixed to each of the connecting rods 9.

Striking bar 13 is pivoted at one end upon one of the side rods and at its opposite end has a hook 43 which hooks over the end of the side bar opposite between collars 4-4 and 45 thereon, as shown in Fig.

To prevent the guide sheaves 10 from rising from the guide rails 5 arms 4-6 swinging from the spindles 12 of the guide sheaves each carlry a roller 47 which runs beneath the guide ra1 In operation the hopper will be loaded while the parts are in position, shown in Figs. 1 and 2. The vehicle is then backed in and by contact with the striking bar pulls the side rods towards the hopper.

The lifting levers 6 being pushed by the connecting rods cause the cross bars 17 to rise until their arbors 20 reach the ends of the slots 21 in the brackets 22.

Continued movement of the vehicle then raises the hopper sufficiently high to clear the end of the vehicle.

Guide sheaves 10 will at that stage be the end of the horizontal portion of guide rails 4.

Further rearward movement of the vehicle causes guide sheaves 10 to pass up the curved extensions of the guide rails. The connecting rods therefor have no further effect upon the ends of levers 6 and the vehicle may be backed beneath the load.

hen it is desired to back the vehicle further the hook at the end of the striking bar is released from the side rod, and the bar swung clear of the vehicle.

Rearward movement of the vehicle causes rope 38 to be pulled and the winch barrel thereby rotated, ropes 28 and 29 being wound upon the barrel while rope 38 unwinds from The pawl 37 by engagement in the ratchet wheel 36 prevents rotation of the winch drum in one direction and the hopper is therefore sustained until the pawl is released from the ratchet wheel, when by using the hand brake 35 the hopper may be lowered to its normal position.

It will be obvious that by using the winch the hopper may be raised without utilizing the rearward movement of a vehicle.

To facilitate tilting of the hopper to discharge its load the movement of levers 5 is limited by chains 19 secured at one end to the lever and at the other end to the foundation plates 1.

Continued rearward movement of the vehicle beyond the position shown in the drawings will affect levers 6 only, and, through the cross bars 17, the hopper will be tilted into a convenient position for the deposit of its load.
