UNITED STATES PATENT OFFICE- MARION R. JENKINS, OF BROWVNING, MISSOURI, ASSIGNOR OF ONEHALF TO WILLIAM J. MOORAY AND BEVERLY D. BOLLIN G, BOTH OF SAME PLACE.

HAY LOADER AND STACKER.

SPECIFICATION forming part of Letters Patent No. 374,966, dated December 20, 1887.

Application filed May 24, 1887. Serial No. 239,253. (N0 model.)

To aZZ whom it may concern:

Be it known that I, MARION R. JENKINs, a citizen of the United States, residing at Browning, Missouri, have invented certain new and useful Improvements in Hay Loaders and Stackers, of which the following is a specification.

The object of my invention is to build a hay-elevator that can be used with equal facility for loading or stacking hay, which can be adjusted to different heights to correspond to the varying height of the stack in process of erection, that automatically discharges its load when it reaches its highest elevation, that automatically throws the elevating-rack into proper position to receive a new load, and that utilizes the weight of the main frame to restore the elevating-rack into position to descend the tracks after automatically discharging a load; and my invention consists in the features and details of construction hereinafter described and claimed.

In the drawings, Figure 1 is a side elevation of my loader and stacker, showing the clevatingrack in three positionsone in full lines at the lower ends of the elevating-tracks in position to be tipped back or drawn up, one in dotted lines tipped back ready to receive a load, and one in dotted lines partially drawn up the elevating-tracks. Fig. 2 is a longitudinal sectional elevation of the lower or front end of the loader with the elevating-rack just beginning to be. tipped back and with the parts enlarged. Fig. 3 is a view of the same with the elevating-rack tipped back and enlarged. Fig. etis a view of the pivot-iron by which such tipping back is effected. Fig. 5 is a perspective View of the rear or upper end of the loader and stacker with the elevatingrack tipping forward to discharge its load onto (Not shown.)

In the drawings, Arepresents the elevating frames or tracks, of which the forward ends rest on the axle and the rear ends extend over the stack or load; 13, braces, of which the forward ends rest on the axle and the rear ends on the ground; 0, braces, of which the forward ends are pivoted to the elevating-frame A and the rear ends rest on the ground; D, braces extending from the rear end of the tracks A to the rear end of the braces B; E, a

Windlass extending across from one brace G to the other; e, a rope or cable running from the juncture of the braces B and D to and around the drum E; F, a chain or cable extending from a lever, f, by which the drum E may be turned-to abracket, f, hereinafter described; G, the elevating-rack; g, fingers or forks in the rear of the load as it is being elevated; g, fingers beneath the load as it is being elevated; H, pivoted sections of track at the forward ends of the elevating-tracks, into which the elevating-rack rolls when it doscends and which are tilted to enable the ele vating-rack to be reloaded; 7L, the turned-up ends of these pivoted sections of track; I, rollers by which the elevating-rack travels on the elevating-track; i, journals or extensions on such rollers to engage with the hooks h of the pivoted section of track H to cause the same to be tilted; J, pivoted sections of track at the rear or upper ends of the elevatingtracks; K, hooked pieces at the sides of the elevating-rack which engage with the projecting ends of a roller or pivot, a, when the rear ends of the elevating-tracks are reached and cause the elevating-track to tip forward to discharge the load, as shown in Fig. 5, and L cords or ropes which pass over the roller a in the elevating-track A and around pulleys a at the rear end of the pivoted extensions to the elevatingtracks and around pulleys a on the prongs g of the elevatingrack and by which the elevatingraok is moved up the track. These ropes have their free ends brought down after passing over the roller or pivot a around pulley c at the rear ends of the pivoted braces C, to be hitched to a horse (not shown) for elevating the load.

In making my improved hay loader and stacker, I make a frame consisting of two parallel pieces, A, of which but the outside of one is shown in Fig. 1, placed a proper distance apart and with their upper edges smooth to form elevating-tracks, which may be braced and supported by cross pieces, as desired. The forward or lower end of this frame A is preferably supported upon the axle of a pair of wheels, to facilitate the moving of theloader from place to place and to enable it to move backward and forward in its operation, as hereinafter described. Extending backward from this axle is a pair of braces, B, of which but the outside of one is shown in Fig. 1, properly braced and connected together by crosspieces and with their rear ends resting upon the ground. Another pair of braces, D, of which but the outside of one is shown in Fig. 1, extends from the rear ends of the braces B up to the rear or upper ends of the elevatingtracks A, to which they are attached. Another pair of braces, D, of which but the outside of one is shown in Fig. 1, passes from the juncture of the braces B and I) up to the elevating-tracks to afford a proper support for this middle portion. Other supports and braces besides the brace D may be added, if desired. Another pair of braces, O, of which but the outside of one is shown in Fig.1, is pivotally connected to the elevating-tracks A near their middle, as shown in Fig. 1, or at such other point thereabout as may be selected. This pair of braces can have any number of cross-pieces to strengthen and stay it as may be desired, and their rear ends are intended to rest upon the ground. In use I prefer to prevent its slipping rearward in the operation of the stacker by driving stakes into the ground, against which its rear ends may rest. A drum, E, crosses from one of the braces O to the other, and is provided with a suitable crank or lever, f, which will afford means for turning it. A rope or cable, 0, passes from a hook at the juncture of the braces B and D and winds around the drum E. From the end of the crank or leverfa chain extends up to a piece, f, which is caused to rise and pull the crank or lever f upward, so as to rotate the drum partially around and wind the rope 6 around it, as hereinafter described.

The lower or forward ends of the elevatingtracks A are provided with pivot pieces H, as plainly shown in Figs. 2, 3, and 4. These pieces H have each an upturned end or hook,

it, Which extends up above the plane of the elevating tracks. The forward end of this piece H lies against the track until tipped up, as shown in Fig. 3 and as hereinafter described. The rearward ends of the elevatingtracks have extensions J pivoted at a and extending down the track a short distance. The pivot or roller a extends out beyond the sides of the pieces A, as shown at one side in Fig. 5, for a purpose hereinafter described, and consists, preferably,of a rod extending through from one side to the other of the track and arranged to rotate, as hereinafter described.

An elevating-rack, G, consisting of a number of arms or prongs, g and g, of which but the outside of the outside ones are shown in Fig. 1, is mounted upon rollers I, having an axle, t, with outwardly-projecting spindles i, adapted to roll up and down the tracks A. The arms or prongs g of this elevating-rack extend upward and the arms or prongs 9 extend rearward when the elevating-rack is in its normal position and conveying a load up the tracks.

The rearward ends of the extended pieces J have U-shaped pieces J riveted to them, in which pulleys a are mounted. Pulleys c are located near the rear end of the braces C, as shown in Fig. 1. The arms 9, which extend over the two tracks a, are provided with pulleys a (Shown in Fig. 1.) Ropes L pass around the pulleys a), and up and around the pulleys a, and back and down over the roller or pivot a, and down around the pulley c, and out a proper distance to attach a horse to the same.

\Vhen the elevating-rack G is allowed to roll down the tracks, which occurs when the ropes L are loosened, it passes down until the spindles i strike against the hooks hon the pivoted piece H, when the weight and momentum of the elevating-rack cause the pivoted pieces H to tip backward, as shown in Fig. 3, and bring the arms 9 into the position shown in Fig. 3 and in dotted lines in Fig. 1, to receive another load of hay from the rakes or gatherers, which are driven up so as to discharge their loads upon the same. When the ropes L are drawn out by the horse or other power, the forks or prongs g are brought up into an upright position and the arms or prongs g are brought intotheir horizontal position, as shown by full lines in Fig. 1. By continued pulling on the ropes L the elevating-rack is run up the tracks until the hooks 'K (shown in dotted lines in Fig. 1 and in full lines in Fig. 5) strike against the extended ends of the rod or roller a, when the progress of the elevating-rack is suddenly stopped, and the pressure of the ropesL over the pulley (1 causes the pivoted extending portions J of the track to tilt or tip up, giving the prongs or forks g a downward slant, so that the load of hay will slide off and be discharged from the same. It will be noticed that these pivoted pieces J extend some distance down the tracks A, below the points where they are pivoted, as will be seen by reference to Figs. 1 and 5. Gross-braces should be located on these extending pieces wherever desired, and to one of these crossbraces X, as shown in Fig. 5, should be attached or fastened the piece f, to which the upper end of the chain F is attached. \Vhen the elevatingrack has caused these pieces J to tip down at their rear ends, the forward ends, with the cross-brace X and piece f, will necessarily be raised and the chain F drawn up. This will raise the crank or leverf, turn the drum E, and wind the ropes 6 around it. This op eration will of course draw the frame forward and upward in proportion to the amount that the rope e is shortened. This is secured from the fact that the braces O are pivoted to the tracks A, and are held from moving backward, when this strain is imposed upon them, by stakes or other obstructions. Vhen the load is discharged and the ropes L are loosened, the weight of the frame will tend to unwind the rope e and to turn the drum E back to its normal position. This will carry the crank f down, and through the chain F will pull the piece f and the front end of the pivoted extensions J down to their normal position on the tracks A. As this is done the incline of the tracks will be restored, and the elevating-rack will be started down again for another load. As the ropes L are loosened, the elevatingrack will run down of its own accord to the position to receive another load, as shown in dotted lines in Fig. 1.

It will be seen that the height of the dis charge end of the elevatingtrack is greater when the ropes or cables 6 are wound around the drum E and the juncture of the braces B D drawn up toward the drum than when they are unwound and the juncture of these braces allowed to move away from the drum. By rotating the drum and adjusting the length of the ropes 6 before hooking the leverf into the links of the chain Fthe height of the discharge can be determined, and by unhooking the lever f from the chain and rotating the drum,

, so as to wind or unwind the ropes or chains e,

the height of the discharge can be changed and varied from time to time at pleasure. The hooking of the leverf into the links of the chain F will prevent the unwinding of the drum.. The operation of the drum and the ropes is to bring the frame-work of the elevating-tracks toward the pivoted braces, or, in other words, to change the angle at which the braces 0 stand to the tracks A as the ends of such tracks are raised or lowered. This will all be readily understood by reference to Fig. l of the drawings.

It will be noticed that the roller a, on which the extensions J are mounted, extends through the frame A and affords stops against which the hooks K on the elevating-rack G strike, so as to cause the extensions J and the rack G to tilt. Any kind of stops that will contact with thehooks, and any kind of hooks or pieces, In, that will contact with stops, soas to arrest the movement of the rack G, will cause this tilting. In like manner the hooks on the pivoted extensions H, against which the spindle on which the rollers I are mounted strikes, may be of any form that will arrest the downward progress of the elevating-rack. In the same way the arm f is merely intended to afford a connection between the chain F and the forward ends of the pivoted extension J, and, as it could be dispensed with and the chain connected directly with such extensions, I do not mean to lay stress upon its employment.

By constructing my loader and stacker as above described it will be seen that the hay is lifted entirely by a rolling instead of a lifting motion; that the pivoted braces 0 enable the upper or rear end of the elevating-tracks to be adjusted to different heights, thus adapting it to the height of a wagon as a loader or to the height of a stack when just commenced; that the elevating-rack carries the grain up and dumps it on the stackin a loose condition, as received from the rakes or gatherers, and that by utilizing the weight of the frame through the arrangement of the drum E, chain F, and other connecting parts the weight of the ele vating-rack is automatically counterbalanced and all other weights dispensed with. These points of ad vantage are not, so far as I know, embodied in any other hay loader or stacker in use.

\Vhat I claim as new, and desire to secure by Letters Patent, is--.

1. The combination of elevatingtracks A, pivoted extensions H, and an elevating-rack, Gr, adapted to tilt such pivoted extensions when run down upon the same, substantially as described.

2. The combination of elevating-tracks A, pivoted extensions H, provided with hooks h, and an elevating-rack, G, mounted on rollers I, provided with spindles t, engaging with the hooks h as the rack G is run upon the pivoted extensions H, whereby the same is tipped and the rack automatically thrown into position to receive a load, substantially as described.

3. The combination of elevating-tracks A, extensions J, an elevating-rack, G, hooks K, and roller (1, on which the extensions J are pivoted, whereby the hooks contact with the roller and tilt the rack, substantially as described.

4. The combination of elevating-tracks A, pivoted extension J, stops a, and an elevatingrack, G, provided with hooks or pieces K, adapted to engage with the stops at when the rack is run upon the extension J, whereby the extension and the rack are caused to tip and the load discharged, substantially as de scribed.

5. The combination, in a hay loader or stacker, of inclined tracks, an elevating-rack having upwardly-extending arms or prongs and rearwardly-extending arms or prongs when the elevating-rack is in its normal posi tion conveying a load up the tracks, pulleys on the rearwardly-extending arms or prongs, and means engagingwith such pulleys for raising and lowering the elevating-rack, substantially as described.

6. The combination of elevatingtracks A, pivoted extensions J, pivoted braces G, roller E, rope e, levcrf, and chain F, communicating with the forward ends of the extensions J, whereby as such extensions are tipped the chain F is drawn up, the roller E rotated, and the main frame lifted to counterbalance the weight of the elevating-rack and restore the parts to their normal position when the load is discharged, substantially as described.

7. The combination of inclined tracks, pivoted braces, a drum, and ropes connecting the drum and the frame-work of thetracks, whereby the height of the discharge end of the tracks may be adjusted by rotating the drum, sub stantially as described.
