STACK EIR.
SPECIFICATION forming part of Letters Patent No. 477,937, dated June 28, 1892. I Application filed January 27,189.2. Serial No. 419,424.5 (No model.)
To all whom/t may concern;
Be it known that I, J AcoB HOLMAN, of Libf erty, in the county of Adams and State of Illinois, have invented certain new and useful Improvements in Stackers; and I do hereby 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 pertains to make and use it, reference being had to the accompanying drawings, which form part ofothis specification.
My invention relates to an improvement in stackers; and it consists in certain novel fea tures of construction and in the combination and arrangement of parts, which will be fully described hereinafter, and more particularly referred to in the claims. l
The object of myinvention is to provide a portable stacker-tower with a verticallyfadjustable track-'arm and supporting-frame therefor and an improved locking mechanism for holding the said frame in the desired adjustment within the tower.
Referring to the accompanying drawings, Figure l is a perspective view of my improved stacker. one of the tower-posts.
The tower consists of the converging uprights A and the central posts B, which are secured together by suitable strips on their outer sides, as shown, and which are supported upon the runners C, upon which the stacker may be moved from place to place. The posts B are formed with the vertical grooves D on their inner sides, and formed near upper ends of the said posts are the slots E, in which are journaled the pulleys F. A short distance below these pulleys and to one side of the grooveD is formed another'slot G, in which is pivoted the hook or catch H.
The adjustable frame consists of the converging uprights I, which are adapted to move vertically between the uprights A B, and the said uprights I I are secured together by the notched cross-pieces J, which move on the posts B, and by this means the frame is guided in its adjustment and prevented from moving laterally in the tower. The opposite crosspieces J are connected by the horizontal bar K. L represents ropes, which are secured at Fig. 2 is a vertical sectional view of` their lower ends to the endsof the said bar and which extend around under the cross.
pieces J, vas shown, and then vertically upward through the grooves D over the pulleys F and down the vouter sides of the tower,where their outer ends are connected, respectively, to the windlass-rollers M, which are suitably mounted on the tower. When it is desired to raise the frame, the said ropesare drawn upon or rather are wound around the saidv rollers M, thus raising the frame to the desired height within the tower. The hooks H are so formed as to allow the cross-pieces J J to move by them in the upward movement; but in moving in the opposite direction the said cross-pieces are caught by the hooks and the frame thus held. It will be understood that either the pieces J or J maybe made to engage the said hooks, according to the height at which it is desired to hold the frame.
Secured to the inner sidesof the frame are the horizontal bars N, having their ends upturned, as shown, which engage the loops O on the upper ends of the tower,'thus greatly strengthening the frame in its extended position.
Suitably supported on the upper end of the may be of any preferred construction and upon which any suitable carriage may be mountedfor transporting the hay-fork from the lower end of thel said track where it receives its load from the wagon to the outer end of the said arm, which projects over the stack. Pulleys P are mounted vin the outer end-.of the arm, over which pass thev operating-ropes.` The track is braced in its extended position by the rods Q, which are connected at their lower ends to the frame, as shown. The post R on the said arm is connected to the opposite ends thereof by the brace-rods S, so that the arm is securely vbraced in its eX- tended position. The arm being capable of a vertical adjustment enables the operator to raise the same as the stack grows in height, thus avoiding the necessity of lifting all the hay to the extreme height before it is dropped upon the stack.` Much labor is thus saved. When it is desiredl to move the stacker from one point to another by lowering the armadjustable frame is the track-arm P, which v IOO supporting frame to its fullest extent, transportation is made much more easy and safe than it would be were the arm non-adj ustable.
Having thus described my invention, I claim- 1. In a stacker, the combination, with a tower and a vertically-adjustable arm-carrying frame moving therein, of horizontal bars secured to the sides of the said frame and which are formed with upturned ends and loops on the tower-frame,which are engaged by the said upturned ends, substantially as shown and described.
2. The combination of a support and vertically-recessed posts B secured thereto, having transverse slots Gbetween their ends and transverse slots E adjacent their upper ends, both of the said slots communicating with the vertical recess of the posts, rollers jonrnaled as shown and described.y
In testimony whereof I ahx my signature in presence of two witnesses. 4
JACOB HOLMAN.
