HAY-STAG KER.

SPECIFICATION formingpart of Letters Patent No. 686,453, dated November 12, 1901.

Application filed February 19, 1901. Serial No. 47,947. (No model.)

To ctZZ whom it may concern.-

Be it known that 1, JAMES F. HAZEL, a citizen of the United States of America, residing at Carrollton, in the county of Carroll and State of Missouri, have invented certain new and useful Improvements in Hay-Stackers; and I do hereby declare that the following is a full, clear, and exact description of the invention,- such as will enable others to make and use the same, reference being had to the accompanying drawings, forming, a part of this specification.

The objects of my invention, primarily, are the reduction of the power ordinarily required to elevate the fork-supporting bars; second, to shorten the fulcrum between the fork-supporting bars and the point at which the power is applied to raise the bars in a Vertical position, and, third,to adjust the position of the hay-dumping fork.

The invention consists in the novel construction and combination of parts such as will be first fully described, and specifically pointed out in the claims.

In the drawings, Figure 1 is a view in perspective of the improved hay-stacker,showing the fork-bars in a horizontal position to receive the hay to be stacked, also showing in dotted lines the position of the parts of the haystacker when the hay-fork is raised a portion of the distance from a horizontal to a vertical position. Fig. 2 is a view in perspective of the hay-stacker,showin g the hay-fork in a vertical position and also the relative position of the elevating devices. Fig. 3 is a detail view, enlarged, of the adjustable support for the haydumping fork.

Similar letters of reference indicate corresponding parts in all the figures of the drawand with the rear ends of said bars a a is connected rigidly the ends of a transverse beam a With the upper edge of the beams a a, at a point upon said beams about one-fourth the distance from the point of connection of the transverse beam (1, with said beam toward the point of connection of the transverse beam a are connected the respective ends of the transverse beam a With the outer side portion of the beams a a, a slight distance in the rear of the vertical plane of the rear edge of the extended ends of the forward beam a are pivotally connected, by the pivots b b", the lower ends of the fork-elevating frame B, consisting of longitudinal bars I) b, the movable ends b b of which bars -when in a normally horizontal position extend a considerable distance beyond the rear ends of the beams a.

With the upper edges and outer end portions 17 b of thevibrating bars I) b is connected rigidly a transverse bar 0, the ends of which bar extend a short distance beyond the plane of the outer sides of said bars. With the upper edges of said bars I) b a short distance in front of the bar 0 and toward the pivotal ends of bars I) b is 'rigidly connected a separate bar D, which is of the same length as bar 0. With the under side portions of the separate bars 0 D at their outer ends are connected the lower ends of the fork-teeth c c, the outer ends of which teeth extend a considerable distance from the transverse bar 0 and in the same longitudinal direction as the bars I) b. A series of teeth 0 are connected with the under side of the transverse bars C D and which extend in parallel planes with each other and the teeth at the ends of said bars 0 D. With the sides of each forktooth care pivotally connected by a pivot e the lower ends of an adjustable fork-tooth e, the upper ends of which series of fork-teeth extend upwardly at an angle to the series of fork-teeth c. The adjustable teeth 0 are connected transversely by a transverse bar E at a point a short distance from the pivoted lower ends of said teeth, so that the series of teeth are moved in unison with each other.

With the outer side of the fork-elevating bars I) b, a short distance from the transverse bar D in the direction of the-pivoted end of said bars, are connected the teeth-adjusting bars F, in the lower ends of which bars are the longitudinal slots f. Through the bars I) I) extend the adjusting screw-bolts f, which extend through the slots f, and upon said bolts are the adjusting-nuts f The upper ends of the bars F F are pivotally connected atj with the sides of the teeth 6' e adjacent to the bars B B at a point a short distance above the transverse bar E, connecting the series of bars e e.

G represents the elevating reach-bar for the elevation of the frame carrying the hayforks, the lower end of which bar is pivotally connected with the upper side of the transverse beam a at a point intermediate the ends of said beam, said lower end, to prevent rotation, being arranged between the upright lugs h it upon the base-plate h, which plate is secured to the beam at. Through the lugs h h and bar G extends the pivot-bolt h The length of the elevatingbar G is such that the upper end when oscillated forwardly and downwardly in the arc of a circle will extend a short distance beyond the pivoted lower ends of bars I) b and also a short distance forwardly of a vertical line extending upwardly from the forward ends of beams a a, so as to obtain the advantage of a downpull upon the transverse bar D upon the bars I) b in advance of the vertical line described. With the bars b b and with the sides and upper end of bar G are connected the bracket-arms g g, which extend at right angles to the said bar and a short distance forwardly from said bar. Between the outer ends of the bracket-arms is a pulley g, which turns upon a pivot 9 extending through said arms 9 g. With the outer ends of the pivot g, which extend beyond the outer sides of the arms g g, are pivotally connected the ends of a clevis g.

In order to support the elevating-bar G laterally, a guide-frame I is provided, which consists of separate guide-bars it, which are obliquely inclined at their lower ends and said ends rigidly connected with the upper side of the forward transverse beam 0, and arranged in a parallel position a short distance apart. The upper ends of the bars i 7; extend rearwardly and upwardly at an angle to the beam at to a position on each side of the elevating-bar G in a vertical line extended upwardly from the beam afiand with the outer side portion of said ends are connected rigidly the upper ends of the standards 2' 91 the lower ends of which standards are inclined outwardly at an angle to said guide-bars t i and connected rigidly with the inner sides of bars b b and are connected with eyebolts g g, which bolts are secured to the upper side of bar D and arranged a short distance apart from each other and form the point of connection of said bar with the bars B B.

L represents an iron weight for imparting the initial rearward movement of the hayforks and bars I) b when in a vertical position and is placed upon the ground in advance of the transverse beam a and in which weight is an eyebolt Z. Said weight is connected with a rope M, in which at a point intermediate the ends of said rope is formed a loop which extends around the transverse beam a and thence through the eyebolt Z in weight L and a night made in said rope to the said eye. Thence the ends m m of said rope (which are of the proper length to permit of the raising of the bars b b to a vertical position) are connected with the eyebolts m m on the u pper side of the transverse bar D.

The tackle for hoisting the bars I) b consists of a pulley n, arranged in position between the lower ends of the guide-bars i 2', near the beam at and upon the pivotn. Upon the beam a is a pulley O, which is secured to said beam by a strap 0, connected with the forward edge of said beam opposite the pulley n. With the clevis g on the upper end of the elevating-bar G is connected one end of a hoisting-rope P, the other end of which rope is extended over the pulley n and is thence extended over the pulley g at the upper end of said bar G, thence extended over the pulley O on beam a and with the free end of said rope is connected a draft-animal or such other power as is convenient to operate the hay-stacker.

With the outer side of the bars I) b, a suitable distance below the upper ends of said bars, is connected one end of the brace-bars b 12 the upper ends of said bars being inclined outwardly and connected with the outer ends of the transverse bar 0 at the upper end of bars I) b.

The position of the various parts of the hay-stacker being as shown in full lines in Fig. 1 and with the fork-teeth c horizontally extended upon the ground, the hay to be stacked is placed in the desired quantity upon said teeth, the load being also retarded from falling forward by the teeth e. Power being applied to the hoisting-rope P, which is transmitted through ropes g g to the upper end of the bars I) b and the hay fork or teeth 0 and e, the upper end of the reach-bar G is readily moved forwardly from its normal vertical position toward beam a*, between the guide-barsz' i of the guide-frame I, and downwardly toward the beam (1 taking up the slack in the ends m m of the rope M and raising the movable ends of bars b b to a vertical position and elevating the load of hay to be stacked. In the movement upwardly of the movable ends of bars I) b the hay upon the teeth 0 shifts its position, and the weight is transferred to the teeth e and carried by IIC . construction.

said teeth to the vertical position described of the barsb b when the hay is dumped upon the ground, and the operation of the stacker repeated until the successive deposits form a stack of the requisite height. In completing the upper and forward movement described, the tension upon the ends m m of rope M raises the weight L from the ground and sustains it in an elevated position. At the same time the tackle-rope P draws the upper end of the reach-bar Gr to a position a short dis tance above the pulley O, and as the end of the bar Gtakes a position forward of the pivoted ends of bars-b b the angle of the rope P gives the'forward impetus to the upper ends of bars I) 'b, and the said bars are raised to a vertical position, and the lower ends of the bars 12 I) contact with beam a as seen in Fig. 2, and while the power is retained upon the end of bar G the vertical position of the bars is maintained. Upon releasing the power upon the hoisting-tackle the weight L causes the first backward movement of the upper ends of the bars 1) b, and as the weight reaches the ground the rearward inclination of the bars is sufficient from their own weight and the forks c c to cause the bars to move toward the ground as the tackle pays out the rope P and the fork-teeth 0 take the position as seen in Fig. l in readiness for the deposit of its load of hay or other material. Upon releasing the nuts on the bolts f the adjusting-bar F is then operated to change the angle of the series of teeth 6' at any desired angle of inclination to the teeth 0, so that when the bars I) b are in a vertical position the discharge of the load of hay is effected with great or less speed, as the movable condition of the material may require.

In my invention I obtain a large per cent. of effective work with a decrease in the weightof the stacker from its simplicity of It is obvious that the guiding of the bar G may be effected from the beam at, and its lateral movement counteracted by the upward extension of lugs h h, and such other modifications employed as are within the scope of the invention.

1 am aware that pivoted frames of various kinds have been employed to'raise the forkelevating frame, the objection to which is in their weight, which has to be overcome before the power is transmitted to the fork-ele-. vating frame. In my invention the fork-elevating bar is composed of light material,

which enables the raising of the fork-elevating frame with the application of less power than in ordinary stackers.

Having fully described my invention, what I now claim as new, and desire to secure by Letters Patent, is

1. In a stacker the combination, with the base-frame, of a fork-elevating frame pivotally connected with the forward end thereof, stationary guide-bars arranged in a parallel position and having their forward ends rigidly connected with the forward end of the base-frame and their rear ends extending upwardlyat an angle to the base-frame, standards connected at their upper ends with the rear ends of said guide-bars, and with the base-frame at their lower ends, an elevatingbar pivotallyconnected with the base-frame at its lower end and movable in the arc of a circle between said stationary guide-bars, hoisting devices connected with the upper end of the elevating-bar and the fork-elevatin g frame, and hoisting-tackle connected with the elevating-bar and with the forward end of the base-frame.

2. In a stacker, the combination, with the base-frame, of a fork-elevating frame pivotally connected with the forward endthereof, stationary guide-bars arranged in a parallel position, and having their forward ends rigidly connected with the forward end of said base-frame and their rear ends extending up wardly at an angle to the base-frame, standards connected at their upper ends with the rear ends of said guide-bars and having their lower ends inclined outwardly and connected with the base-frame, an elevating-bar pivotally connected with the base-frame, and movable in the arc of a circle between said stationary guidebars, a pulley pivotally connected with the said guide-bars near the forward ends thereof, elevating-ropes connected with the upper end of the elevating-bar and also with the fork-elevating frame, and hoisting-tackle connected with the elevating-bar and also with the forward end of the baseframe and having a loop thereof extending over the pulley on the guide-bars, and means for retracting the elevated fork-supporting frame.
