CONVEYER.

Specification of Letters Patent.

Patented Feb. 19, 1918.

Application filed March 2, 1917. Serial No. 152,124.

To all whom it may concern:

Be it known that I, AUGUST Awiscnus, a subject of the Emperor of Germany, resident of Benson, county of Douglas, and State of Nebraska, have invented certain new and useful Improvements in Conveyors, of which the following is aspecification.

This invention relates to improvements in devices for collecting and conveying various substances, such as manure, etc, and has as its principal object the provision of means whereby forked grabs may be operated to engage the material to be moved, the same raised and deposited in a vehicle so as to be transported wherever desired.

This and other like objects are attained by the novel construction and combination of parts hereafter described and shown in the accompanying drawings, forming a part of this specification, and in which Figure 1 is a rear end View, partially in section, showing the construction of the truck and hoisting device.

Fig. 2 is a fragmental side elevation of the grab and its operating means.

Fig. 3 is an enlarged fragmental sectional view showing the construction of the pulley over which the raising rope runs, and means for holding it in engagement.

Fig. t is a top plan view of the same and Fig. 5 is a side elevational view 'of the same, but showing the parts in another position.

In the drawings, a platform or truck 10 is shown to be supported by pairs of Wheels at the rear and front of the apparatus, the same being adapted to be moved by horses.

Centrally disposed on the truck frame is a rigid standard 15 to which are attached braces 16.

In the central support 15 is a vertical shaft 18 connected by a pair of bevel gears 20 with a horizontal shaft 21 upon which is attached an operating crank handle 22, so that by rotating the handle the shaft 18 is caused to revolve.

Rigidly secured to the upper end of the shaft 18 is a hollow arm 24 containing a mast 25, at the end of which is rotatably secured a pulley 26, over which runs a rope 27, one end of which may be attached to a whippletree, so that a horse can be engaged with it for raising the load engaged by the grab forks 30, arranged in a series of pairs and copies of this patent may be obtained for in such manner that the same can be opened through a lever 31, and pull cord 32 the central part of the rab framebeing secured to the opposite end of the rope 2?.

Attached to the-rope, near the grab, is a weight 33, adapted, when the rope is drawn upward, to make contact with a lever 3%, pivoted on the pin 35 and provided with an operating cord 36, by which it may be raised, the lever being held in normal contact with the pulley by the pull springs 37.

\Vhen the weight 33 makes contact with the lower side of the lever 31, the latter is caused to rise, allowing the weight to pass, and preventing its return as the lever 31 is snapped downward below the weight, and is adapted to sustain a portion of the load.

When it is desired to free the forks suspended by the rope 27, the latter is slackened and the cord 36 pulled, raising the lever 3a and permitting the weight 33 to pass so that the grab may be lowered as desired.

When it is desired to use the grab, the same is lowered in an open position and engaged with the material to be raised, which is preferably formed into a hillock, whereupon the rope 27 is pulled, raising the materialengaged by the grab until the weight 33 is passed over the lever 3i, holding the load suspended.

The crank 22 may then be operated, moving the mast arm 25 carrying the load from one side to the other of the platform 10 or deposited at either endthereon.

Having thus described my invention, what- I claim as new, and desire to secure by Let ters Patent, is I The combination with a suspended rope having a weight at one end and a winding means at the other, of a pulley over which said rope operates, a latch having a bifurcated opening through which said rope passes, the free end of said latch being frictionally engageable with the periphery of said pulley, a spring normally holding said latch in engagement, means for manually releasing said latch, and means combined with said rope for locking said latch under pressure of said grab when said grab is raised to its highest position.

In testimony whereof I have affixed my signature this 31st day of January, 1917.

AUGUST AWISCHUS.
