1 398 284; Specification of Letters Patent. Pgrtqgntgfl Hwy, 22, 19231,

Application filed October 20, 1820.

To all whom it may concern.

Be it known that l, J ACOB A. SoHowAL'rnR, a citizen of the United States, residing near Newton, in the county of Harvey and State of Kansas, have invented a new and useful Headed-Grain Stacker, of which the following is a specification.

My present invention is a portable hoist, particularly for loading and unloading, stacking and transferring headed grain, hay and fodder from barges, wagons, barns, and the like, or handling the material directly on the ground.

The principal object of the invention is to produce a hoist of the abovementioned type which is simple in construction, economical to produce and which is effective and etlicient for its purposes.

One of the main features of the present invention resides in the manner in which the derrick or hoist may be collapsed to enable it to be moved under telephone and tele graph wires and under shelter of the ordinary barn sheds.

The invention further resides in the sundry details of construction, combination and arrangement of parts hereinafter more fully described and pointed out in the appended claims. 1

In this specification and the annexed drawings, the invention is disclosed in the form in which it is considered to be the best, but the invention is not limited to such form because it is capable of being embodied in other forms; and it is to be understood that in andby the claims following the description herein it is intended to cover the invention in whatever form it may embody within the scope thereof.

in the drawings:

Serial No. 413,148.

Fig. 8 is a plan view of the turn-table for the mast, and i Fig. 9 is a fragmentary detail view in perspective of the catch member between the turn-table 19 and bearing plate 17 when the mast is collapsed as shown in dotted lines Fig. 2.

Referring particularly to the drawings: the hoist comprises a portable base frame 34, to rest upon the ground and provided with side runners at, having at its forward end traction wheel 28. Arranged-over the forward end portion of the base frame is a circular bearing ring 17 supported in position by the uprights or standards 35 rising from the base frame and secured in downwardly depending channel sockets b onthe ring. A mast 36 is provided for the hoist, and may be of any suitable construction, however in the present instance is. shown as constructed of side members 0 connected in spaced relation by spacing blocks (Z arranged at an intermediate point of the side members. Disposed between and secured to the lower ends of the side member 0 of the mast is a spindle c which is nor-. mally received in a'socket 14 secured to the forwa rd end bar f of the base frame 34. The upper ends of the side member 0 of the mast converge and are held in substantially juxtarelation by the strap member 8 extending over the ends of the side members. lhe mastextends -through an opening 19 in a turn-table 19, which is secured to the mast intermediate its ends, as shown in Figs. 1, 7 and 8, by means of fastenings members extending through flanges 19 of the turntable.

The turn-table 19 rests upon the ring 17 and rotatably supports the mast in conjunction with socket 14L against lateral movement. The mast is further supported in position against lateral movement by guycables 37 secured at one end to a swivel 7 on a spindle 3S, projecting upwardly from the strap 8 of the mast. Tic other ends of the guy-cables secured in any suitable manner. such as by stakes, to the ground.

T he mast strengthened on its rear face 7y a truss rod 12 secured at its upper end .o a stirrup 11 arranged over the top end 0. he mast. and at its other end to a U shapen trap or stirrup 13, secured to the lower end Jortion of the mast considerably below the sion on the rod. This rod 12 is spaced at an intermediate point in its length from the mast by a block or bridge 39. A boom has one end secured to the mast between the side members 0 thereof, by means of a stationary pivot 41, located substantially midway between the top end of the mast and theturn-table 19.

The boom 40 consists of spaced and substantially parallel side members '9 maintained in spaced relation by a spacing memher it. The outer end of the boom has a stirrup 3 extending around its end and side faces, as shown in Fig. 6, and secured to the boom by means of a bolt 6 extending therethrough.

The outer end of the boom 40 is raised and lowered by means of a cable 5 having one end secured to a yoke 4 connected to opposite ends of the bolt 6.

The cable 5 passes ver pulley 10, secured to the upper end of the mast, and extends downwardly to a drum 21 secured to the lower end of the mast by means of

brackets

20 and 22. The drum 21 is operated by the usual hand-crank 23, and may be held against unreeling rotation by any suitable means such as a pawl and ratchet.

A sling 42 is suspended from the outer end of the boom by means of a hoisting c1.- ble 43 having one end secured to the sling and passing between the block-and-tackle 44 suspended from hooks 1 disposed adjustably in notches 45 in the outer top surface of the boom, and the block and tackle 46 connected to the sling. From the blockand-tackle 44 the cable 43 passes to a pulley 47 journaled between the side members. 0 of the mast and immediately below the boom pivot 41. From the pulley 47 the cable 43 passes downwardly to a pulley 48 secured to the end bar f of the base frame. The cable 43 may be operated either manually, or by draft or motive power in a manner which is well understood. 1

In order to permit the hoist to be knocked down with the outer end of the boom resting; ,n the base frame 84 so that it may be stowed away, or to permit its passage under low trees and the like, the turn-table bearing ring; 17 is formed on its front side with an arcuate opening 17 substantially the width of the mast at that point, and the socket 3.4 is pr vided with a removable side The spring 13 is interposed between wall 15, see Figs. 3, 4 and 5, thereby permitting the mast to be pivoted on the bearing; ring 17 and moved to. the position shown in dotted lines in Fig. 2. The wall 15 of the socket 14 is maintained in position by pins 16.

Of course, to accomplish this the mast is rotated 180 from its full line position shown in "Figs. 1 and 2.

The turn-table 19 is provided with a laterally projecting lug 33 formed with a concaved face 00 adapted to engage'in the stirrup 18 provided on the rear side of the hearing ring 17 The member 33 engaging in the member 18 prevents accidental displacement of the mast when in the position shown in dotted lines in Fig. 2, and also acts as a pivot upon which the mast will fulcrum whenreturning it to its upright or full-line position. 7 p

The wheels 28 of the hoisting rig are mounted on laterally extending supporting axles 29, as shown in Figs. 1 and 2, the axles being pivoted at points 30 in the front end bar 7 of the base frame to swing vertical.

Levers 24 are arranged on each side of the base frame and pivotally secured thereto, as at 27, and overlie the axles 29. The other ends of the lever 24 are provided with fasteners 25 engageable in a complemental fastening member 26. It is therefore understood that when the

fastening members

25 and 26 are engaged, the lever 24 will lie substantially parallel with the side members a of the base-frame, and bear upon the distal end of the axles 29, so as to raise the frame member above the ground and support its forward end on the wheels.

As will be clearly understood, with the parts in the position shown in Figs. 1 and 2, the entire base frame rests fully upon the ground in order to give a substantial and firm base for the hoisting rig when in operation.

From the foregoing, it will be clear that the present invention provides a hoisting rigwhich may be readily collapsed and of a light construction in order that it may be portaged, and at the same time providing one having great durability and economical to produce.
