HOISTING-MACI-IINE.

To all 107mm it may concern:

Be it known that I, GEORGE M. EICHINGER, a citizen of the United States, residing at Clear Lake, in the county of Deuel and State of South Dakota, have invented certain new and useful Improvements in Hoisting-Machines, of which the following is a specification, reference being had to the accompanying drawings.

This invention comprehends certain new and useful improvements in hoisting machines and has for its primary object to pro vide a hoisting machine which will be of such construction that it may be readily emolo ed for stackin ha I loadin manure 1 .L b 7 t: 7

elevating grain and various other purposes for which hoisting machines are employed.

A further object is to provide a machine of this character which will be of extremely simple construction and operation and highly efficient in use and which may be employed for a number of different purposes, thereby making it unnecessary to employ separate machines for stacking hay, loading manure, elevating grain, etc.

A further object is to provide a machine of this character including standards mounted upon a turn table and having a vertically movable frame engaged upon the standards with a removable rack or the like pivoted in an extended portion of the frame and means for locking the pivoted member in horizontal position, thereby preventing the load from sliding off of the pivoted member during movement of the frame.

A further object is to provide a device of this character which will be strong and durable and which will be constructed in such manner that the turn table may be readily turned to change the position of the frame and the member pivoted in said frame and then locked in position to prevent further horizomal movement of said frame and pivoted member.

A further object is to generally improve and simplify the construction and operation of device of this character and thereby increase the efficiency and at the same time reduce the cost of the same.

With these and other objects in view, my invention consists in certain novel constructions combinations and arrangements of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawing, in which,

Figure 1 is a side elevational view of my Specification of Letters Patent.

complete device; Fig. 2 is a cross-sectional view on the line 22 of Fig. 1; Fig. 3 is a cross-sectional view on the line 33 of Fig. 1; Fig. at is a detail View of the ball upon which the turn table rotates; Fig. 5 is a detail plan view of a second form of rack adapted to be pivotally mounted in the ad justable movable frame; and Fig. 6 is a detail perspective view of a grain box adapted to be pivotally mounted in the adjustable or movable frame when the machine'is to be employed for hoisting grain or the like.

Referring more specifically to the drawing in which similar reference characters designate corresponding parts throughout the several views, 1 designates the base having the semi-circular member 2 mounted therein, said semi-circular member having its thick portion countersunk in the base 1 and having a thin Semi-circular flange portion 3 spaced slightly above the base 1 and provided with notches 4 in its curved edge, the purpose of which will presently appear. The semi-circular member 2 is preferably formed of two sections, as shown in Fig. 2, and is preferably secured to the base 1 by means of the bolts 5 extending through the thick or main portion of the sections of the semi-circular member 2 and through the thin portion of the base 1.

Mounted upon the semi-circular member 2 is the turn table 6 which is mount-ed for rotation upon said member 2 by means of the ball 7 connected to the under face of the turn table 6 and engaged in the socket 8 in the semi-circular member 2 at the center of said member 2. The turn table 6 has the spaced

sockets

9 and 10 formed upon its upper face, within which the lower ends of the standards 11 and 12, respectively, are secured by means of the pins 13 and let. The turn table 6 also has an arm projecting from the center of its curved edge with a handle 16 formed upon its outer end. A bell crank lever 17 is pivoted to a depending portion of the handle 16, as shown at 18 and has one arm normally parallel with and spaced from the horizontal or extended portion of the handle 16 while the opposite arm of the bell crank lever is pivoted at its extremity to the outer end of the latch bar 19 which is slid ably engaged through the depending ears 20 of the arm 15 and has its inner end adapted for engagement in the notches t in the edge of the semicircular member 2, as will be clearly understood. A spring 21 is engaged around the latch bar 19 and has one end bearing against one of the ears 20 while the opposite end bears against the collar 22 mounted upon the latch bar between the ears 20 it be g understood that the spring 21 is also posit" uied between the ears 20 and serves to normally retain the inner end of the latch bar in engagement with one of the notches l.

it will understood that the standard 12 extends for some distance above the standard 11. and the standards are connected near the upper end oi. the short standard 11, by means of the connecting and bracing arm 23 which has the cults 2t upon its opposite ends engaged around the standards 11 and 12, as will be clearly understood. The triangular bracket Q5 is mounted upon the upper extended end of the standard 12, as shown at 96 and has a depending perforated ear 2? at its lower point through which a swinging bracket 28 is engaged, said bra hot 28 havin a pulley 29 mounted therein tor cooperation with lower or second pulley 30 mounted in the bracket 31 extending upwardly from the vertically movable frame.

The movable frame comprises spaced upper horizontal members positioned upon the opposite sides of the standards 11 and and connected by the transverse s ialts which have the anti-friction rollers mounted thereon for engagement against the opposite sides of the standards 11 and 12, it being understood that the shafts 34land rollers 35 are positioned between the standards and also outwardly of each standard. The spaced upper horizontal members have their forward ends directed downwardly at an angle, as shown at 86 and then axtendcd in a horizontal direction as shown at 37', the purpose of which will presently appear. T 1e upper horizontal members 33 are connected with a pair of lower horizontal frame members 38, by means of the vertical frame members 39 and the lower spaced horizontal members 38 are connected to one another by means of the lower transverse shafts 10 corresponding to the shafts 3 and having rollers 41 mounted thereon which correspond to and cooperate with the rollers 35, thereby making it possible to move the "frame 372 vertically upon the standards 1.1 and 12 with the minimum amount of friction between the parts, The outer ends of the lower spaced horizontal frame members :38 are connected with the inclined or downwardly directed members 01" the upper frame members as shown at #2 and are preferably formed integral with said members.

Que end of a frame raising cable 1-3 is oured to the swinging bracket member 28 \nd the cable is extended downwardly and engaged around the lower pulley 80 then brought upwardly and engaged around the upper pulley E29 and again extended downwardly past the lower pulley 30. The cable is then engaged around a third pulley llmounted in the bracket l?) secured to the upper face of the turn table 6 and extended in a horizontal direction above the turn table, as shown in Fig. 1, to be operated by an engine or draft animals or any othe' suitable means, as will be readily nnderstood.

A shaft 46 is removably engaged through the free extremities of the horizontal portions 37 of the frame members and is adapted to also extend through the depending perforated cars 17 of a hay rack 18 or the like positioned between the said horizontal portions 37 of the members it will be understood that the hay rack 48 is of such length as to extend beyond the horizontal portions 3? of the members 33 and owing to the position 01 the lugs between the ends of the horizontal portions 3?, the rear edge of the rack 4L8 rests above said horizontal portions, thereby preventing rearward tilting of the rack. fr trip lever all is mounted upon the rod 50 extending transversely through the members at the junction 01 the horizontal portions 37 with the downwardly or inclined portion 36 of said members and has a forwardly directed point or nose 51 normally extending over the rear edge of the rack l-S to hold the same in horizontal position when a load is posi tioned upon said rack. The trip lever 19 is resiliently retained in normal position by means of the spring 52 having one end socured to the lever and its opposite end se cured to a bar 53 extending transversely through the downwardly directed or inclined portion 36 01 the members 33 and the trip lever 49 may be released, when desired, by pulling upon the cord secured by one end to the rear end of the trip lever, as will be clearly apparent.

lVhen the device is properly positioned, it may be anchored by means or the anchoring cables 55 connected at their upper ends to the uppermost portion of the triangular bracket 25, as shown at 56 while their lower ends are connected to the anchoring post driven into the ground at spaced d stances from the base 1 and preferably upon opposite sides and rearwardly oi the l i ;e it being understood that while I preferred three anchor' posts 57 and cables r suitable number may be employed.

From the foregoing it will be understood that the frame is lowered to place the U41 rack lnear the ground to receive the hay or other material to be raised for ring or other purposes and after the material has been placed upon the rack, the cable al is operated to raise the rack upon. the standards 11 and 12 and the turn table (3 is secured, as previously described, to swing the rack as to proper position, after which the cord 54: is operated to release the trip lever 49, thereby allowing the rack etS to tilt forwardly upon the shaft as and allow the material to slide off of the said rack. It will be understood that after the cable as is relieved of strain, the weight of the frame and parts carried thereby will cause the same to again move downwardly upon the standards 11 and 12, the anti-friction rollers 35 and ll, reducing the friction to the minimum.

In Fig. 5 I have shown a slatted or open platform as having its ends inclined downwardly, as will be clearly understood by referring to the drawings and it will be understood that this platform may be readily secured upon the transverse shaft ac after removal of the rack i8, and thereby adapting the machine to handling or hoisting manure or the like.

In Fig. 6 I have shown a grain box d8 which may be substituted if desired, for the rack 4:8 to adapt the machine to handle grain and like material, the grain box 48 having the front portions of its sides directed slightly toward one another to provide a narrow front open end which is normally closed by the door 59 upon the forward end of the lever 58 fulcrumed upon the upper free end of the post 60 having its lower bent end secured centrally upon the upper face of the bottom of the grain box. The rear or free end of the lever 58 is extended beyond the rear end of the box and suitably perforated to receive a suitable op crating cord 61 connected with the cord 54. for operating the trip lever. It will also be understood that the grain box 48 has suit able perforated ears secured to the under face of the bottom of said box to receive the transverse shaft to, one of the ears being shown in Fig. 6 and designated by the numeral 62.

It will be understood that any other suitable forms of racks, platforms or boxes may be removably secured upon the transverse shaft ac, if desired. It will also be understood that various changes in the details of construction and arrangements of parts may be made within the scope of the appended claims without departing from the spirit of my invention.
