This invention relates to certain novel im prove'ments in the construction of machines which are adapted for elevating hay and depositing it upon .stacks in the field.
The main object of my invention is to so construct a hay-elevator that the crane-arm, from which the load of hay is suspended by means of a fork and draft-rope, will automatically swing from the point at .which said. arm is loaded to the desired position over the stack for discharging the load,'thereby relieving the horse of much labor and greatly facilitating the work of transferring hay from a Wagon to a stack, as will be hereinafter dedescribed.
Another object of my invention is to arrange the pulleys'over which the draft and suspension-rope-is passed, in such manner that the act of drawing on one end of this rope will not be liable to upset or tilt'the machine, for the reason that the weight on one side, and the power which is applied on the opposite side to lift thisvweight, will about balance the machine, as wiil be hereinafter described.
.Another object of iny invention is to seconstruct the frame which sustains the crane-arm,
and toV apr-ly this frame to a portable sled,l
that it shall'ihave a very wide base and yet al'- low the crane to describe nearly a half-circlein swin ging to and from the stack, said frame also being provided with tie-rods and a metal- ,lic cap, which latter is adapted to receive and confine the upper ends of the frame-beams in place and to serve as a bearing for the axisof the crane, whether a central `post be used or not, as will'be hereinafter described.
To enable others skilled in the art to understand my invention, I will describe its construction and operation. 4
ln the accompanying drawings, Arepresents a sled, consisting of two side runners, which are connected together by means of transverse beams, upon lwhich 4a longitudinal beam, a, is secured.- A
B B B are three beams, which forma tripod for sustaining the crane-arm C upon the sled. The upper ends of these beams are s'ecured in slots or sockets, which are formed in' the sides of a cast-metal cap,D, shown in Fig. 3, and the lower ends of said beams are secured in shoes b b b', which are bolted to the sled. The two shoes b b are located at the eX- tremities of the central beam, a, and the shoe b is bolted upon the upper edge of one ot' the sled-runners, as shown in Figs. 2 and 4. B-y
thus arranging the legs of thel tripod a free space is left between the two legs B B forthe crane-arm braces to swing from one end to the other of the machine-a distance which is nearly equal toa semicircle. The overhanging load of the crane-arm and the weight which .is added to this arm are sustained partly by the leg B' and partly by the tie-rods E E,'which are attached by means of eycbolts to `the-sled at their lower ends, .and to the cap D by means of nuts, by meansof which latter this cap is drawn down flrmlyupon the legs ofthe tripod, so as to stien the entire structure and secure it rigidlyfto the sled.
At an intermediate point .between the two.
legs B B, and in the center of the sled, is a circular inclined plane, the axis of the circle coinciding with the axis of motionlof the cranearm C, which would be indicated by a line,-
dropped from the center of the pin B projecting from the top of .the cap D, as lshown in Figs. 1, 2, 4, and 5.
.TheMcrane-arm C consists of au inclined beam,
which is sustained by means ol' inclined braces, C' O2, that are connected at their lower ends to a short vertical post.l1`,the lower end of which passesloosely through thebeaiu n. Thebra'ces G' C2 are secured by means ot' short braces e to the lower end of the crane-arm, as shown in Figs. 1, et, and 5. 'Ille lower part ot' thc frame of the crane is supported upon the inclined plane G by means ot' a roller, d, the shaft ol" which passes transversely through the post F and is secured to this post. The upper end of the craneis pivoted to the vertical pin 1)' by means ot"` a perforated plate, c, which is bolted to the lower end of the cranearni. This crane may be constructed with a central post, F', extending from the beam n on the sledv through the cap-plate D, and projecting sonie distance above this plate. ln this form ot crane the arm C may besecured to its postiii a position perpendicular to it,'and braced by means ot' horizontal and inclined braces, as represented in Fig. 6.
The cap-plate l) should be made in two sections to receive the cylindrical portion of the post F', and to allow this post to rise or fall as it is turned to the rightor to the`lel't. Where the central post, F', iseniploycd the rollerbearing d is applied to it and moves upon they circular inclined plane G precisely in the inanuer described forthe crane, (shown in Figs. 1,
y. 2, 4, and 5,) which has no central post extruding from the beam a to the tmp-piece-l1v Near the upper end ot' the `jib or crane-arm C is a pulley, g, and near the lower end of this jib is another pulley, g'. Over these two pulleys g g' passes the draft-rope h, which is carried down and passed through a" pulleyblock, j, that is secured to the sled atan intermediate point 'between the incliurd plane G and the foot of the beam B', as shown in Fig. 4. From this block j the rope passes over a pulley on the beam B', and thence to the horse, which walks in a line with the line of the pulleys. To the opposite end of. the rope k a fork of any suitable description may be attached for gathering the load of hay and hohling it until elevated andinoved to a proper position over the stack for discharging it thereon.
-The operation ot1 transferring hay or other such position with respect to the stack that this stack is atone end of the machine andthe wagon at the opposite end. The operator now' draws the crane-arm round over the wagon, which lifts the roller-bearing d to the highest point of the inclined plane.` The fork is then loaded, after which the horse is started from the machine, so as to elevate the fork with its load to the proper height.- This being done the horse is stopped and the crane-arm allowed to swing round otl itself over the stack. After the hay has been dropped from the fork upon the stack the operator draws the crane-arm around over the wagon again for anothcrload, and at the same time backs the horse so that. lle can start olf` again when 'the forli has been loaded. It is not intended that the horse should have any other work to perl'orln than that ot' elevating the loud ot' hay. The weight of such load will cause the crane or'jib to swing around to the position for discharging the load, in consequence of its lower end being supported upon an inclined plane. W'hen the load has been dropped upon the staclrthe attendant having hold of the guy-rope can easily move the jib back and draw down the fork.
Having thus described my invention, what I claim as new, and desire to secure by LettersPatent, Vis- 1. So constructing a machine adapted for elevating hay or other material that it will automatically convey its load to the point of delivery at the pleasure ofthe attendant, substantially as described.
'2. A swinging crane orjib of an elevatingmachine,- in combination with a sled, tripodframe, tie-rods E E, and cap D, all arranged substantially as described.
Witness my hand in the matter of my application for a patent on an improved hay-elevator this 2d day of September, 1865.
