EARTH, SAND, GRAVEL, AND MANURE LOADER.

Application led September 17, 1927. Serial No. 220,190.

My invention relates to improvements in ear-th, sand, gravel and manure loaders and consists of a frame composed of ground skids, having uprights at one end thereof; inclined track skids with circular runners mounted thereon and having the lower ends supported on the ground skids at about the centre of same, while the upper ends pass through the two uprights and are bolted thereto. A dumping .platform made of plank and covered with an iron apron, rests on one end of the ground skids, and is hauled up the inclined track skids by means of cables which are attached to one end of same, while the other end of the platform is fitted with two track pulleys which run on the circular runners. lrVhen the dumping platform reaches the upper end of the inclined track it extends over two or three feet to balance the load and it is then stopped by two hooks, which are attached to the underneath portion of the platform and engage with a rod at the upper end of the inclined track. This rod has a loose sleeve which turns with the hooks, thereby eliminating all friction between the hooks and the rod and it also acts as a spacer between the two inclined track skids. The platform is tilted upwards, allowing the material to be dumped into a wagon placed underneath the end of the inclined track.

1 attain these objects by means of the mechanism more particularly described and as illustrated in the accompanying drawings, in which Fig. 1 is a side elevation of machine showing the dumping platform in position, and in dotted lines when dumping.

Fig. 2 is a plan View of the machine, showing in dotted lines the position of the dumping platform for loading.

Fig. 3 is an end elevation of the machine.

Fig. 4 is a perspective'view of the dumping platform.

Similar figures refer to similar parts throughout the various views.

1 are the ground skids formed of heavy timber. 2 are the uprights which are bolted to the ground skids 1 and are erected either perpendicular or slightly inclined backwards to make it more convenient for dumping. 3 and 4 are cross and diagonal braces attached to ground skids 1. 5 are the inclined track skids which have one end bolted about midway to the ground skids while the other end passes through the uprights 2 and are bolted to same. The top of the incline is of such height so as to allow sufficient room for a wagon to stand underneath to receive the material. The ends of the track skid 5 project beyond the uprights 2 and are braced to same by means of the rods 6 and 7, which have one end attached to an iron bar 8 which connect the two track skids 5. The upper ends of rods 6 pass through the top bar 9 which connects the two uprights 2, and having threaded en-ds engaged by nuts to take up the tension, while the lower rods 7 are attachedin a similar way to small castings 10 attached to each of the uprights 2.

A dumping platform 11, having a bottom made of plank and covered with sheet iron, rests on one end of ground skids 1. The two sides and rear end have raised edges formed of timber which serve to hold the material, the forward end being left clear to allow for dumping.

At the front end of the dumping platform 11 are small grooved track wheels 12 which have a bearing on an axle formed on a shaft 13 which is counter-sunk into the fioor of the platform and secured thereto by U'-bolts. The grooved track wheels 12 are set back from the edge of the dumping platform 11 and lit in a recess formed in the side timbers. This protects the wheels and keeps them from becoming clogged with dirt.

Two flat iron strips 14 are ailixed to the top of the ground skids 1 and serve as slides for the dumping platform. Two runners or guard rails 15 are placed underneath the platform and act as guides to steady it when in operation. Side strips 16 are attached to the ground skids l on either side and come Hush with the raised edges of the dumping platform and actas guides, also keeping the dirt from falling on the runners underneath the platform. Circular iron runners 17 are attached to the top of the inclined track skids 5 for the dumping platform to move on by means of grooved track wheels 12. 18 is a Stringer placed midway between the two ground skids 1 and supported at one end by the cross brace 3 and at the other end by a stay rod 19 connecting the two ground skids. 2() is a circular iron runner attached to the Stringer 18 and on which the grooved track pulley 21 runs, said pulley being attached to the rear of the dumping platform 11, and allows of an easy runway back for the platform. The platform 11 is pulled up in a horizontal position by means of cables 22 which hook into strips 23 which are fastened I underneath the platform, the ends of which are bent over and come through underneath the rear raised edge of the platfoim and are then bent upwards to allow of the cable 22 being attached. The cables 22 pass through pulleys 24 which aie liu-ng from the top bar 9 and down through pulleys 25 which are hung at the bottom of the uprights 2 and' aie oai'- ried fioin there and attached to double-tree 26, if horses are used, or can be attached to a hoisting engine.

Twol arms 27 are attached, one on either side, to the inclined track skids 5 and are pivoted to same. The top ends are connected a rod 28 on which are spaced two coneshaped spool rollers 29' under which the cables 22 pass.

When the rear end of the dumping platform 2 passes through the two arms 27, the said arms being pivoted and slightly inclined forward, drop down until the rod 28 rests on the inclined track-skids 5. The dumping platform continues to the top of the inclined track, and the bar 8, which has a loose sleeve 30, engages with the two stop hooks 3l which are attached to the underneath portion of the platform. The platform is then tilted to an angle sufficient to allow of its contents being dumped into a wagon placed at the end of the inclined track, and it is then returned to its position for loading at the base of the incline. Vhen the platform reaches the foot of the incline, two pick-up hooks 32 attached to the top of the rear bar of the platform, pass underneath the two cone-shaped spool rollers 29, lifting the arms 27 and rod 28 a suHicient heightl to allow the dumping platform to pass underneath and into the loading i truck 34 is placed under the rear end of the machine and the front end Vis raised and at tached to a wagon for hauling.

In placing the loader it is not necessary to dig a pit, as a runway is formed of earth to the height of the side strips 16.

The cost of handling material with this inachine is cut vdown to at least half over the sole use of fresnos or Scrapers, particularly where the lianl is over several hundred yards.

What I claim is In a loading device,y a pair of ground skids, vertical uprights therefrom, a dumping platforni having running gear at one end thereof a pair of inclined trackways supported by said uprights and skids, a'paii' of hauling cables secured to the other end of said platform and trained over pulleys supported by said uprights, and a pair of arms pivotally secured to said inclined tiackways intermediate of the length thereof and joined by a rod over said cables and having cone pulleys thereon in engagement with said cables in their taut and slack conditions.
