HAY-STACKER.

Patented Jan. 9, 1906.

Application filed September 9, 1905. Serial No. 277,794.

To all whom it may concern:

Be it known that we, ABNER M. STEVENS and GEORGE E. STEVENS, citizens of the United States, residing at Melvern, in the county of Osage and State of Kansas, have invented new and useful Improvements in Hay-Stackers, of which the following is a specification.

The present invention relates to portable hay-stackers of that type which are designed for building field-stacks of hay.

One of the objects of the present invention is to secure a stacker which will deliver its load centrally of the stack, to the end that a stack may be built up in a uniform manner and danger of collapse during the building because of irregular piling may be avoided, and, furthermore, that the stack when finished may be of regular outline to insure sta' bility and good water-shedding qualities.

A further object of the invention is to provide a carrier for the stacker which may be manipulated with a single rope, which will run with but little friction or drag, be accurately guided in making its traverse along the stacker-tracks, dump its load when it reaches the end of its upward movement at the top of the stacker, and which will automatically return to the stacker-foot after having delivered its load.

Other novel features will be pointed out in the description which follows hereinafter, reference being had to the accompanying drawings, in the several figures of which like reference-numerals refer to like parts, and in the claims appended hereunto we will set forth those features of our invention which we deem to be novel.

In the drawings herewith, Figure 1 is a side elevation of our improved stacker, showing the carrier at its lowermost or loading position, parts of the frame being broken away for clearness of illustration. Fig. 2 is a bottom view of the carrier. Fig. 3 is a sectional view of the upper part of the stacker, showing the carrier in dumping position. Fig. 4 is a view similar to Fig. 3, showing the carrier starting on its return movement.

Referring to the drawings, 2 denotes the bed-sills of the stacker-frame, which are connected by cross-beams 3. At the forward end of the stacker is an axle 4, having supporting-wheels 5, by means of which the stacker may be readily moved from place to place. Rising from the forward end of the sill-frame above described are uprights 6, which serve to support the track-beams 7, said track-beams being secured at their lower ends in any suitable manner to the rear end of the sill-frame, as shown in Fig. 1. To give a braced and rigid frame, diagonal trussbeams 9 are provided, which extend from the forward transverse sill 3 of the stacker-frame to the upper ends of the track-beams 7 and serve to support the extreme upper end of the said track-beams. Secured at the upper ends of the track-beams 7 are the delivery tracks 10, which extend at substantially right angles from the track-beams 7 outwardly, so as to give a good 'overhang, the point of juncture between the track-beams 7 and the delivery track-beams 10 being rounded off, as shown, to give a continuous track-surface for the carrier andone without abrupt angles. The said delivery-track beams 10 are joined at their outer ends by a transverse beam 11, (see Fig. 1,) and the outer ends of the deliverytracks are tied to and supported from the main frame by means of diagonal truss-beams 12,which beams may be pinned or secured to the diagonal beams 9 at their crossing-points substantially midway their length and at their other ends are secured to the uprights 6, as shown in Fig. 1. This construction insures great rigidity of the stacker-frame, for it will be observed that by the arrangement of trussbeams 9 and 12 a substantially X-shaped truss is secured which very effectively braces the stacker -frame. Furthermore, this arrangement of X-truss gives the upper end of the stacker an overhang, so that the hay will be dropped by the carrier, hereinafter to be described,at a point some distance from the forward end of the sill-frame, and thus we are enabled by the use of our improved stacker to build up a symmetrical and uniform stack.

The carrier, which is shown in bottom plan in Fig. 2 and in two different positions on the track in Figs. 3 and 4, is substantially L- shaped and is made up of a main sill 13, having upright arms or slats 14 and runner-beams 15, which are arranged in pairs on each side of the carrier, so that they straddle the trackbeams 7 when in position on the stackerframe, said runner-beams 15 having cross boards or slats 16 to form a bed for the load. The said carrier is preferably provided at its rear end with rollers 17, which are mounted on each side between and beneath the runnerbeams 15 and normally ride upon the trackbeams 7 as the carrier travels up and down the stacker-frame, these rollers being of considerable size and forming the main supporting means for the carrier during its travel. The carrier is also provided with a pair of smaller rollers 18, mounted between the runner-beams 15 at their forward ends, said rollers 18 being preferably mounted on the upper side of the eams 15, so that the said beams may drop sufficiently to straddle the .track-beams 7, and yet the carrier will be wholly sustained by the

rollers

17 and 18, placed on the under and upper sides, respectively, of the runnerbeams. In order to insure maintenance of the carrier-frame in alinement with the trackbeams of the stacker, it is preferably provided with projecting guide-pieces 19, carried by the inner runner-beams 15, so that when the carrier is in position on the track these guides 19 project between the trackbeams 7 of the frame and aid in holding the carrier in proper position and direct it as it travels along the tracks. The said guides 19 are preferably wedge-shaped or pointed at their lower ends, so that they will readily enter between the track-beams 7 as the carrier tilts from one position to the other during its operation.

The carrier is preferably so constructed that the arms 14 will overbalance the runnerbeams 15 and bed when the carrier is empty and no pull is being exerted on the draft appliances, (presently to be described,) so that when the loaded carrier tops the inclined tracks of the stacker-frame and dumps its load it will as soon as it is empty automatically tilt backwardly and ride down the trackbeams 7. (See Figs. 3 and 4.)

Secured to the carrier is the single draftrope 20, by means of which the carrier and its load are drawn up the track-beams 7 of the stacker, this rope 20 passing over a pulley 23 on the cross-beam 11 of the delivery-track and thence to a second pulley 21, secured to the axle 4.

In operation the carrier when in its lowermost position, as shown in Fig. 1, is loaded and then by means of the draft-rope 20 is drawn upwardly along the track-beams 7 until it reaches the top of the stacker at the point of juncture of the track-beams 7 and the delivery-track beams 10. At this point, by reason of its load and the pull upon the draftrope 20, the carrier will automatically tilt to the position shown in Fig. 3 and deliver its load, the guides 19 striking the stop-bar 22, spanning the delivery-track 10, and, stopping the carrier in the position shown, cause the hay to slide off and be delivered to the stack beneath. the overhanging delivery end of the stacker. been delivered the heavier arms or upright slats 14 of the carrier will overbalance the runner-beams 15 and the carrier will automatically tilt to its normal position and run backwardly down the track to loading position, the rollers 17 riding down the tracks 7, while the rollers 18 will ride up the tracks 10 and over the rounded top of the meeting tracks, as shown in Fig. 4.

From the foregoing it will be seen that we have produced a stacker which is extremely simple in construction, eflicient and automatic in operation, one in which by the use of but a single draft-rope we are able to handle and manipulate the carrier in such manner as to produce the necessary movements thereof, and one which will form a symmetrical and uniform stack.

We have of course shown and described a particular embodiment of our invention herein; but it will'be understood that the construction may be varied to a considerable extent without departing from the spirit of our invention, and we do not, therefore, limit ourselves to anything shown or described except so far as-we are limited by the prior art to which this invention belongs.
