HENRY T. SINCLAIR, OF VVATROUS, TERRITORY OF NEYV MEXICO.

HAY-STACKER.

SPECIFICATION forming part of Letters Patent N 0. 560,372, dated May 19, 1896.

Application filed August 2, 1894. Serial No, 519,248. (No model.) I

T0 at whom it may concern:

Be it known that I, HENRY T. SINCLAIR, a

citizen of the United States, residing at Wat rous, in the county of Mora and Territory of New Mexico, have invented certain new and useful Improvements in Hay-Stackers; 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 letters of reference marked thereon, which form a part of this specification.

The special object of the invention is to produce for public use a machine by which hay, alfalfa, or straw may be conveniently stacked in large quantities by the aid of a horse or other power.

Figure 1 of the drawings is a perspective view showing the stacker set up ready for work; Fig. 2, a vertical section of foot-block and mast; Fig. 3, a detail view of the footblock; Fig. 4, a detail view of a derrick hinged to the mast.

In the drawings, A represents the footblock, in which is stepped or pivoted the vertical mast B. The latter is pivoted at top in the bearings G O, which are held in position on the journal I) by means of the guy-ropes D on opposite sides of the mast.

E is a derrick pivoted to the mast by means of two metallic straps F F, curved to permit the derrick to fall to a horizontal position, with its rear end abutting against the mast. The derrick is bifurcated at the outer end, the prongs being connected by the cross-pins e e, on the inner one of which turns the pulley G.

II is the hoisting-rope, one end of which is made fast to the derrick cross-pin e, the rope being then carried down under the hay-fork pulley I, then up over the derrick-pulley G, then over a mast-pulley J, then down over a mast-pulley K on a mast-arm k, then over the mast-pulleys LM, and then down through the mast and foot-lolock under a foot-block pulley N. The mast-arms 7t 7t" are arranged on the opposite side of the mast to that from which the derrick projects and are braced by the jointed rods 0, which are connected with the mast at the upper and lower ends. The derrick is supported'by a brace-rope P, extending from the outer end thereof to the top of the mast.

The mastis set sufficiently out of a perpendicular to cause the traveling motion from load to stack, while the load is brought as near as possible centrally beneath the outer end of derrick-that is, on a circle corresponding to theme which would be described by the outer end of the derrick if rotated.

I am aware that the mast has been used heretofore on an incline or out of a perpendicular; also, that derricks have been used with double blocks and pulleys, together with two lifting ropes, but I operate by single pulleys and a single rope, which both lifts the rope and the arm or boom.

In buildinga stack of hay the boom is held in a horizontal position by a rope or other flexible connection attached to the top of the mast and to the outer end of the boom, but when the body of the stack is completed and it is to be topped off or drawn to a point at the top this flexible connection allows the boom to be raised at the outer end by allowing the load to come up against the under side of the boom and thus force it up to the required height.

I am also aware that a double-pulley footblock has been used with a pivot in atop concavity and all the connection between mast and foot-block on top of the latter, the mast being held in said concavity by the said pivot; but I use a flat iron plate and a pipe passing through it to connect the mast and foot-block,

wherein is placed a single pulley.

WVhat I claim as new, and desire to protect by Letters Patent, is-

In a hay-stacker, an open-slotted foot-block, A, provided with a pulley N, an iron plate 8, mounted on said foot-block,a mast, B, stepped on said plate, a pipe 'n, passed through said plate and connecting said mast with said foot block, a derrick E, provided with curved 9 straps F, pivotally connected with said mast, a pulley and lift-rope connected with the outer end of said derrick, a hay-fork pulley in a loop of said lift-rope, pulley G, carried by the derrick, and pulleys J, K, L and M, carried by the mast, said lift-rope being passed over said pulleys and thence downward through the pipe n, and about the pulley N, substan: tially as and for the purposes described."

In testimony whereof I affix my signature in presence of two witnesses.

HENRY T. SINCLAIR.
