HAY-STACKER.

SPECIFICATION forming part of Letters Patent No. 477,878, dated June 28, 1892.

Application filed April 30, 1892.

To all whom it may concern: .7

Be it known that I, FRAN W. WHITNEY, a citizen of the United States, residing at \Vessington Springs, in thecounty of J erauld and State of South Dakota, have invented certain new and useful Improvements in Hay-Stackers; and I do hereby declare the following to be a full, clear, and exact description of the nvention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to hoisting, and more especially to that class of devices known as hay-stackers, and the object of the same is to elfect certain improvements in devices of this character.

To this end the invention consists in the construction hereinafter more fully described and claimed, and as illustrated on the accompanying drawings, Wherein- Figure l is a general perspective view of my improved device complete ready for operation. Fig. 2 is a perspective detail of the telescoping members of the tripod slightly separated, showing, also, the stay-chains at the lower end of the rear leg thereof. Fig. 3 is a bottom plan View of a bundle of hay, showing my improved sling as surrounding and supporting the same. Fig. 4 is an enlarged plan View of the catch I use on the sling, closed in full lines and open in dotted lines. Fig. 5 is a perspective detail of the parts of this catch slightly separated.

Referring to the said drawings, the letter T designates the tripod or derrick, R the operating or elevating rope, S the sling, H the hay, and G the catches, these parts being of thefollowingspecific construction,preferably, although such changes and alterations therein may be made as come within the spirit of my invention and will be apparent to the skilled mechanic.

The tm'p0d.This consists of two front legs 1 1, pivoted at their upper ends on a bolt 2 through the upper member 3 of the rear leg, which may be solid like the others, but is preferably extensible or telescoping. In that event the lower membereof this leg has side flanges 4', forming a channel, in which the upper Serial No. 431,343. (No model.)

member 3 slides longitudinally, and pins or bolts 5 are preferably passed through aligning holes 6 in the two members to lock them in adjusted position. By this means this rear leg may be allowed to adjust itself, or it may be manually adjusted in length; and, if desired, a similar construction may also be employedin the front legs, although I have thus far found such adjustment desirable only at the rear of the tripod. 7 7 are two stay-chains secured to the rear leg and to pins 8 8 in the ground, whereby the resistance of the work being done will not tend to topple the tripod over forward.

The operating-rope.Th is is lettered R, and leads from a whiiiletree 10 (or other source of power) under a wheel 11 on the rear leg, up along'beneath the same to and over a block 12, suspended from the apex of the tripod, v(preferably by a clevis 13, hung on the bolt 2,) and thence between the front legs 1 and to the center of The sZing.2O is a ring, which may have a central cross-bar 21, to which the rope R is attached, and radiating from this ring are several ropes or lines, preferably four, as shown at 22 22 23 23, the two latter having eyes 24 2st at their outer free ends and the two former being connected at their outer ends with a distending bar 25, which is preferably (although not necessarily) provided. The eyes 24 are adapted to be engaged under hooks or pegs 26, which are sunk in the ground, as indicated in Fig. 1, or they may. be detachably engaged with the catches O, as shown in Fig. 3, and at this time the distending bar 25 (if used) causes the sling to embrace the bundle of hay near its ends with the apparent advantages.

The catches.Secured, as by bolts 30, to the bar 25, near its ends, are the stationary members of the two (or more) t rip-catches 0. Each of such members 31 stands across the bar and has at one end an eye 32, to which the outer end of a line 22 is connected, while at the other side of the bar it is curved around, as at 33, having a spur 34twithin the hook thus formed. The pivoted member of each catch comprises a double body 35, whose sides spur and extend thence upward to an eye 37,

wherein is. fastened the trip-rope 38. Below the point-36 the sides stand astride the stationary member and follow nearly the same curve, as at 39, and a pivot 40 is passed through the tips of the three books formed by these members. Said trip-rope preferably leads from the two eyes 37 (or from all such eyes, if more than two catches be used) to a point 38, where they are connected, and thence a common rope 38 is led to within convenient reach of the operator.

The operation of this improvedhay-stacker is as follows: The tripod is set up adjacent the point where it is desired the stack shall be formed, the rear leg adjusted, and staychains applied, and the rope R properly strung, as described. Pegs or hooks 26 are then secured, the eyes 24 engaged under them, and the hooks sunk into the ground below the surface thereof at a point which will be forward of the stack that is to be formed. The sling above described is then spread out in the form of a letter X, its front feet being at these eyes, its center connecting with the rope R, and its rear feet being held separated by the bar 25, (if emp1oyed,) which lies on the ground parallel with the line of the hooks. The bay to be stacked is then drawn from the cooks or hills by any approved pattern of horse-rake or by hand and is moved over and upon the sling as the latter lies on the ground. Obviously the hooks by being entirely sunken will not catch in the hay, yet will prevent the sling being displaced. When a sufficiently-large bundle of hay has been piled onto the sling, the operator disengages the eyes 24 from the hooks, (as by pulling the pegs forcibly from the ground,) passes them over the bundle, and engages them with the aligned hooks 33 and 39 of the catches. Signal is then passed to the boy or attendant in rear of the tripod and he starts his horse to draw on the rope R. It will be noticed that this rope passes now under the bundle to the center of the X- shaped sling. Hence as the rope is drawn the bundle is first rolled over outward or away from the tripod, so as to bring the ring 20 uppermost and the catches O at the bot tom of the bundle, and thereafter continued pull on the rope R elevates the bundle into the tripod and into position to form the stack. When at the proper point, the operator draws quickly 011 the trip-rope and the catches are opened, as seen in dotted lines in Fig. 4, when the eyes 24 simultaneously pass out and the sling opens at the bottom to drop the bundle directly onto the spot where the stack is to be formed. Thisoperation is repeated as the stack is built, and the growing of the latter in size will soon render it desirable that the front legs of the tripod be set farther forward. However, as such setting would lower the pivotal bolt just at the time when the height of the stack makes it desirable that the block 12 be not lowered, I consider it desirable that the rear-leg should be extensible, as above described. As the front legs are set forward, this rear leg is then extended, as will be understood, and as such enlargement of the tripod takes place the sling will be secured to the ground a little forward of HS or ginal position, in order that its operation will not be interfered with by the then larger stack.

WVith respect to the specific form of catches which I employ in this connection, it will be seen that since the pivot is at the tips of the hooks, the eye 24, when it stands in the throats of these hooks, will tend to draw the connecting-point 36 against the stationary member above the spur rather than to cause the catch to open or dump. At this time, too, the spur projects across the mouth of the aligned hooks, and thus prevents any accidental displacement of the eye 24. When the pivoted jmember is turned by the trip-rope, the eye '24 is caused to pass over the pivot- 40 and the'strain of the sling then draws on this eye and results in the positive opening of the catch.

\Vhat is claimed as new is 1. In a hay-stacker, the combination, with the elevating device, of a hay-sling consisting of a central ring, an elevating-rope secured to a cross-bar therein, radiating lines leading .from said ring, eyes at the freeends'of half of said lines, peg-hooks adapted to engage said eyes and to be seated in the ground, and catches carried by the outer ends of the other .half of said lines and also adapted to engage said eyes, the Whole operating substantially as described.

2. In a hay-stacker, the combination, w th the elevating device, of a hay-sling consist ng of four lines radiating from a common point to which the elevating-rope is secured, eyes at the free ends of two said lines, catches havin g eyes, to which the outer ends of the other lines are secured, a bar across which said catches are secured near its ends, and a forked trip-rope leading to said catches, substantially as described.

3. In a hay-stacker, the combination, with the elevating devices and a sling comprising an X-shaped figure of rope, having eyes at two of its feet, of two catches, each consisting of a stationary member having an eye in one end, to which the outer end of the rope forming the other foot is connected and having its other end hooked, a pivoted member, also having an eye at one end and a hook at the other, a pivot between these members at the extremities of their hooks, and a triprope leading from the eye in the pivoted member, all substantially as and for the pur- IIO arymember having an eye in one end, ahook a trip-rope leading from the eye of the pivat the other end, and a spur within said hook, a pivoted member, also having an eye at one end and a hook at the other, this member being double and standing 'ast'ride the stationary member, its sides connected at a pointaboye said spur and the tip of its hook pivoted to that of the other hook, and

oteid member, all substantially as set forth. :0
