STACKING- MACHINE.

SPECIFICATION forming part of Letters Patent No.322,106, dated/July 14, 1885.

Application filed August 26, 1884.

To all whom it may concern:

Be it known that I, BYRON JACKSON, of the city and county of San Francisco, and State of California, have invented an Improvement in StackingMaohines; and I hereby declare the' following to be a full, clear, and exact description thereof.

My invention relates to 'a machine for stack` ing hay and grain; and it consists in certain details oi' construction hereinafter described and claimed, reference being had to the accompanying drawings, in which- Figure I is a side elevation of my machine, showing also the wagon with the net within it, and attached to the swinging frame, said framebeing also shown by dotted lines in position to discharge. Fig. 2 is a plan view of the machine. Fig. 8 is a perspective View of the machine. Fig. 4L is an enlarged perspective view showing part of the ridge-beam, the weight, the supportingropes, and the pulleys W. Fig. 5 shows the meeting-point of the timbers F F and braces H and the uniting-bracket. Fig. 6 shows the meeting point of the timbers E and G, and the unitingbracket at this point. Fig. 7 `is an enlarged perspective view of one of the base-timbers, A, the upright rear timber, E, transverse and diagonal bracing-timbers with their unitingbrackets; also showing the hinged arms D standing vertically, and the bracket and hinge.

A is the base of my machine, consisting of two timbers and joined at one end, while the others are separated in the form of a triangle, and have the traveling wheels C turning on suitable journals or axles, so as to support these ends. The front end is supported upon a single wheel, B, which may be a casterwheel, or may have a pole by which it is turned and the machine guided from place to place. From this angle, which I call the front of the machine, an upright, F, extends upward, sloping also somewhat backward, and

from the rear portion of the base-timbers, A,

two other uprights, E, extend upward and backward, meeting so as to form av triangle in themselves, and having their upper ends connected with the upright F by a ridgebeam or timber, G.

I and J are cast-fra1nes or brackets, within which pulleys are journaled over which the hoisting-rope passes, as will be more fully (No model.)

explained hereinafter. These brackets may have sockets or depressions into which the timbers-E, F, and G are fitted and bolted, and the bearing I is also adapted to receive the upper end of the inclined braces H, which extend-down across the uprights E, being bolted to them, and thence backward to the castings, to which wheels C are journaled, being also securely fastened to these. The uprights E are being bolted at the base of the cross-pieces K, and these pieces K are bolted to the main sills A, thus saving any angular cut in the timber which might weaken them, and they are easily made. By this construction I produce aframe which is braced iu every direc tion and can be made very much lighter than if rectangular, and needs no supplemental braces.

At the points M where the timbers H cross and are secured tothe uprights E are hinged the rear ends of the frame or arms D, by which the load is to be raised from the wagon to the stack. These arms D are made in two pieces, sprung apa-rt in the middle, with intermediate cross-timber, so as to form a rigid truss-beam, and they have their outer ends united by a similar truss-beam, l?, while the frame Q eX- tends between them at a point just forward of the upright F, thus forming a sort of rectangular space between the side arms, D, and the front and rear timbers, I? and Q, between which the net S with its load may be suspended. The arms D are hinged at such a height above the ground that their outer ends will be high enough to allow the team of horses with the wagon containing the net and the load to be driven beneath them, and attachments are fixed to each corner of the rectangular frame formed bythe arms and the bars D, P, and Q, as before described, so that the net may be connected therewith, and with its whole load raised out of the wagon, carried upward and backward, as shown by dotted lines-in Fig.,1, so as to discharge the load upon the stack.

L is a windlass or wheel and axle of such proportionate diameter that the team may be attached to the rope passing around the larger IOO so as to be secured to the frame Q to elevate the arms D with the load.

T is a counterbalance-weight of considerable size, supported upon two parallel parts of the ropes U by means of two pulleys which are journaled to the weight, so as to rest upon these ropes. These two sets of ropes extend from the points V and WV down to the arms D, where they are secured near the ends of the transverse frame Q, the two ropes extend ing parallel with each other between the pulleys W and XV', so that the weight may hang upon these two parts between those points.

By this arrangement it will be seen that the weight is equally supported by these two independent ropes, and it will not be necessary to exercise much care in getting the load centrally placed in the net, as each independent rope supports one end or side of the net, and ifthere should be more weight upon one side than the other the tendency of that side to pull downward would be resisted by the oouni'erbalance weight, which would derive more of its support from that rope than the other. Vhen the load is lifted so as to discharge it, the counterbalance-weight Tsinks downward toward the ground by the slacken` ing ofits ropes, and when the arms D are again dropped to a position over the wagon this counterbalanceweight is raised and its power to resist the weight of these arms increases as the ropes U gradually become straightened between pulleys XV and XV', so tha-t when the l net has nally reached the wagon there will be nearly or quite an exact balance.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-` l. In a portable stackingmachine, the triangularly-arranged rear uprights and the single front upright, with the uniting beam or ridge, in combination with the triangularly`arranged diagonal braces H, and the brackets whereby the meeting angles are united and the whole frame supported Without separate braces, substantially as herein described.

2. In a stacking-machine, the combination of the triangular base with the uprights arranged as shown, the hinged swinging arms journaled at the rear, transverse beams l? and Q, detachable wagoirnet, and means for raising the arms, substantially as herein described.

3. In astacking-m'achine, the combination ot' a frame, arms D hinged thereto, fastenings upon said arms, a detachable lifting-net, and mechanism by which the loaded net may be carried up over the frame to discharge its contents upon the stack and returned to its place in the Wagon, substantially as herein described.

In Witness whereof I have hereunto set my hand.

BYRON JACKSON.
