HAYSTACKER.

Application filed July 18,

To all whom it may concern:

Be it known that I, Josnrn H. Corn, a citizen of the United States, residing at the city and county of Denver and State of Colorado, have invented certain new and useful Improvements in l-laystackers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

My inventionrela-tes to improvements in hay stackers or rickers of that class embodying a stacker head or elevating means, married by lifting arms mo ably attached to a base-support and operative thru the me ;.ium of dr i; appliances connected thereto to facilitate the formation of a rick or stack. An example of this class of stacker is shown in patent number granted to me June 8, 1909. The present invention relates specifically to a truck which is attached to the base of the stacker and which is used in transporting the stacker from place to place.

I am aware that it is old to equip the base of a hayst-acker with wheels to facilitate transportation thereof, and in my patent above referred to, I have shown wheels for this purpose, but whenthe wheels are secured to the base in the manner shown in my former patent, it usually becomes necessary to dig a hole in the ground for each wheel in order that the base may rest solidly on the ground; this necessitates the performance of considerable extra labor besides when it is desired to move the stacker the holes are an impediment, which greatly increases the labor required to do so.

It is the object of this invention to provide a truck for this type of haystacker, that will permit the base'to rest solidly upon vthe ground without the necessity of digging holes therein to accommodate the wheels. The relationship between my truck, the base and the lifter frame is such that the latter 1921. Serial No. 485,720.

will automatically raise the base from the ground and cause it to be supported on the truck whenever it 15 desired to do so, thereby dispensing", with the necessity of heavy lifting.

I will now describe my invention in detail by reference to the accompanying drawings in which Fig. 1 is a plan view ofmy improved stacker withthe truck in operative position.

Fig. 2 is a side elevation of thesame.

F 3 is a side elevation of my stacker with the truck in inoperative position.

Fig. l is side elevation showing the base of the stacker resting on the ground'and the lifter frame in extended vertical position.

F 5 is a detail showing the construction of my truck, and

G is a detail of the sliding connection between the arms of the lifter frame.

In the drawings the same reference characters represent the same parts thruout the several views.

Let the numeral 5 represent in its entirety the base, which consists of two parallel bars 6, (shown in the drawing as built up of two separate pieces a and 1 which. are held in spaced relation by transverse bars 7, 6, and 9, and in angular relation by braces 10. Secured to the forward end of the base 5 is a vertical frame consisting of uprights 11, which have their lower ends bolted to cross piece 9, and their upper ends connected by a transverse horizontal bar 12; this frame is held in its vertical position by diagonal braces 13, each of which comprises two bars bolted to opposite sides of the top portion of upright bars 11, and. have their lower ends bolted to opposite sides of bars Each of said diagonal brace bars 13 has one end of a brace 14- secured thereto by notches, or otherwise, and the other end secured to the base member 6 by bolts or similar means- Pivotally connected between each pair of braces 1% by means of a bolt 15 is one end of bars 16, which form the sides of the pivoted lifter frame. Bars 16 are held in spaced relation by transverse bars 17 and 18, and in angular relation by diagonal braces 19. Near the outer end of each bar 16 is a long narrow slot 20 the upper side of which is formed by an iron bar 21 held in place on bar 16 by bolts 22, all as shown in detail in Fig. 6. Sliding in slots 20 are flat iron bars 23 whose inner ends are bolted to a transverse bar 24, and whose outer ends are provided with an eyelet for the reception of one end of springs 25, the other ends of which are anchored to bar 16 by means .of eyelets 26, which are secured thereto by bolts 27. The bar 24 and springs 25 form a resilient stop or buffer and cooperate with the other elements in a manner to be hereinafter described.

Slidingly connected to bars .16 are bars 28, which form the stacker head frame; The upper or outer ends of bars 28 are held in spaced relation by transverse bars 29 and 30, which form part of the stacker-head 100. Secured to the lower ends of bars 28 are hooked members 31, which hold them in slidable engagement with bar 16 and se cured to transverse bar 18,-are hooked members 32 whose hooked ends are in engagement with bars 28'. This connection permits of free sliding movement between bars 16 and 28, and at the same time holds them securely in a predetermined relation,

Secured to each side of the inner ends of bars 6 isasteel plate or bar 33 to the upper ends of which is pivoted, by means of a bolt 34, a link 35 the upper end of which passes between the brace members 13 and is guided thereby. Pivotally attached to the upper end of link 35 is another link member 36 the other end of which is pivotally attached bya removable pin 37 to the sliding stacker head frame bars 28. The bars 28 are provided with a plurality of holes 38 for the reception of pivot pin 37 whereby the link 36 maybe secured to bars 28 at various points in order to vary the lift of the stacker-head in a mannerthat will hereinafter appear. Links3 6 are each provided with a depending stop-39, the object of which is to engage-the endsof transverse bar 24 and tension the springs 25 and thereby produce resilient buffer action at the end of each upward throw of the stacker-head.

In order to raise the stacker-head 100, and cooperating frame, and move the same about the pivots 15, I have provided an A frame40 which comprises two main frame members 41, held in spaced relation'by cross bars 42 and 43, the whole being pivotally mounted 'on'the base bars 6 by means of pivots 44.

Secured to the top of-the A frame and pivotally mounted between the ends of the same on a bolt 45. is a pulley 46 and a I U-shapedanchoringmember 47, as well as an anchoring device 48. Secured to theanchoring device 48 are two tension rods whose lower ends are pivotally connected to the outer end of bars 16 at point 50. Having their lower ends secured to the lower ends of braces 13 by one of the bolts that' holds the latter to bar 6 are brace members 51. The upper ends of braces 51 are held together by a bolt 52, which also serves as a pivot for pulley 53. Tothe top of the framework formed by members 11, 12 and 51 are secured two Z-shaped members 54 which are pivoted to said framework by a bolt 52. Bars 51 have their lower ends secured to the base members 6, and with members 11 form a triangular structure which is rigid. The ends 56 of members 54 have a bolt 57 joining them, the same being true for the other ends 58. The function performed by parts 56 and 58 being to guide the rope and to prevent it from jumping o from the pulleys.

A rope 59 has one end secured to the U-shaped anchoring member 47 and passes thence over pulley 55, thence back to and around pulley 46, thence over pulley 53 and down to and around pulley 61, whence it passes outwardly to one side of the frame.

'If a horse is hitched to the end of rope 59 and made-to exerta suflicient pull thereon, A frame 40 will be rotated on its pivots 44, and since the tip of this frame is connected to the stacker-head frameby means of rods 49, the latter will be caused to rotate about its pivots 15 until the parts finally assume the position shown in Fig. 4. It will be I noted here that as the stacker-head frame rotates about pivots 15, link 36 whose inner end is pivotally connected to the upper end of link 35 and consequently stationary, thru its pivotal connection with bar 28, at 37, causes the latter to slide along bar 16 and thus extend-the stacker-head lifting frame. When the lifting frame approaches the position shown in Fig. 4, stops'39 engage the ends of bar 24 and put springs: 25 under tension which increases as the frame continues to move about its until finally bars 23 reach theend slot 20 and form a positive stop. I

I desire to callattention at this point to the action of fromjumping ofi the pulleys and This member has beenso designed that the part 56 projects over the sides of the pulley at the point where the rope is tangent pivots of the thereto, and maintains this relationship as .1;

the pulley .46 moves about its pivot 45, be-

ing held in this relative position by the tension of the ropes passing over pulley 55.

In order to facilitate moving,l have provided the outer end of the base with a two if.

wheeled truck. The wheels 62 are mounted on an axle 6,3, which passes thru holes inthesides of suitable angle bars 64', which have one end pivoted to a block 65 secured by bolts 66 to transverse bar 7 The other lifting E member 54 in keepingthe rope 12.

end of angle bars 64 are secured by bolts 67 to a transverse bar 68 and are held in proper right angular relation therewith by means of braces 69 Slidably connected to bar 68 by means of a U-shaped strap 69 are short bars 70 one end of which rests upon the projecting ends of the angle irons 64. When bars 70 occupy the position shown in Fig. 5, the stacker-head frame may assume the position shown in Fig. 3 with the tines of the stacker head resting on the ground and the base frame also resting on the ground; this is the proper position for operation. When it is desired to move the stacker, the stackerhead frame is raised and bars 70 shoved out to the position shown in dotted lines in Fig. 5, the stacker head frame is then lowered and will rest upon the projecting ends of bars 70, and, since the stacker head and frame are of considerable weight, they overbalance the weight due to the base frame, and lift the latter off the ground as shown in Fig. 2. Since the wheels are placed in such a position that the axles are almost directly beneath the center of gravity, the inner end of the stacker will rest upon the ground with but little weight, the stacker can therefore be easily moved by merely hitching a horse or a team of horses to the inner end thereof. l'Vhen the stacker has been moved to its new location the stacker head frame is raised sufficiently to permit the base frame bars 6 to rest upon the ground, the bars 70 are then withdrawn to the position indicated in full lines in Fig. 5, and the stacker is ready to operate.
