To all whom it may concern:
Be it known that I, SAMUEL M. GEHo, a citizen of the United States, residing at Grantsville, in the county of Calhoun and State of West Virginia, have invented cen; tain new and useful Improvements in Hay and Straw Stackers, of which the following is a specification, reference being had to the accompanying drawings.
This invention relates to stackers, and particularly to means for building stacks having what may be termed a bee-hive.
shape. I
The general object of the invention is to provide a stack of this character including a form into which straw or hay may be filled, and provide means whereby the straw may be carried to the top of the form and discharged thereinto and which may be adjusted upward as the form is filled.
A further object of the invention is to provide means wherebythe sections of the form may be released from engagement with each other to remove it from the stack and means for supporting the other sections on the frame of the machine when it is desired to transport the form and the supporting frame to a new section.
A further object is to improve the details of construction of forms of this character V and provide a form which has but little weight and the sections of which may be readily handled.
Other objects will appear in the course of the following description.
M invention is illustrated in the accompanying drawings, wherein Figure 1 is a side elevation of a stacker constructed in accordance with my invention, the supporting frame being lowered to its first position;
Fig. 2 is a like View to Fig. 1 but showing the supporting or elevating frame raised to its second position; i 1
Fig. 3 is an-end elevation of the stacker, the reaches 20 being omitted;
V Fig. 41 is an'elevation of a stack showing the form sections partially removed;
Fig. 5 is a top plan view of one of the reaches;
Fig. 6 is a top plan view of the form; Fig. 7 is a fragmentary vertical section of one of the form staves or sections;
Fig. 8 is a top plan view of the machine to show the manner in which the form sections are supported when disassembled, the frame bars 13 being in section;
Fig. 9 is an elevation of one of the yokes Fig. 10 is a fragmentary elevation of the connected frame members 13 showing the knuckled joint between the frame members.
Referring to these drawings, it will be seen that for the purpose of forming the hay or straw into a stack, I provide a form 10, which has the general shape of a stack to be made and which is composed of a plurality of sections held in engagement with each other in any suitable manner, as for instance, by one or more detachable bands or hoops 11, preferably having turn-buckles thereon wherebv they mave be tightened up around the form or whereby the bands may be entirely released from the form. This form may be made of slats, staves or in any other suitable manner, but preferably the form will be made of a plurality of segmental solid sections or blocks a from 2 to 4: inches thick and the upper part b of each form sections may be made'of light staves or'of sheet metal. This form is open at the bottom and has lateral openings at the upper portion of the form on opposite sides, as at 12, these openings constituting filling openings and extending downward to the top of the form to any desired distance.
Coacting with this form is a frame composed of opposed sections A and B, each section comprising the slightly curved side beams 13 and suitable braces connecting the side beams and holding them in parallel relation. The side beams of each section are pivotally connected to each other, as by knuckles 14 and 14?, these knuckles forming hinge joints and being connected by a pintle 15.- The.lower ends of these frames A and B are supported upon trucks including axles 16 and wheels 17. A hoop 18 surrounds the lower end of the form and is provided with eyes 18 at a plurality of points. Connected to these eyes are a plurality of telescopic reaches, each reach comprising the sections 19 and 20, as illustrated in Fig. 5. The section 19 is swingingly conbeam 13 and the section 20 is pivotally connected to the corresponding eye 18 on the hoop 18 by a shackle or clevis 21. The section 19 is longitudinall slotted so that the section 20 may be shifted in this slot and the sections 19 and 20 are provided with alined perforations to receive holding pins 22 to thereby provide for lengthening or shortening these reaches when the frame composed of the sections A and B is lowered to the position shown in Fig. 1 or raised to the position shown in Fig. 2. Pivotally connected to the beams 13 are the tables 23 which may be folded over upon the sections A- and B but which when in use extend outward in horizontal planes to receive the hay or straw for forming the stack.
For the purpose of carrying the hay or straw upward upon the frames A and B and discharging the material into the form 10, I- provide endless belts 24, one disposed in connection with each frame A- or B. These belts pass over the rollers 25 and 26 mounted between the members 13'. Mounted on the shaft of the roller 26 is a gear wheel 27 which is engaged by a relatively large gear wheel 28 having acrank pin 29. Cone necting the crank pins 29: is. a connecting rod 30 which is longitudinally slotted as at 31; A pin 32 projects outward from an adjustable pin plate 32 which is pinned to'a head 15 onthe pintle 15 at one end thereof,
and the walls of the slot 31v ride on this.
pin. Power may be applied to the shaftsof the rollers 26 in any suitable way. For instance, I3 have shown on the shaft of the wheel 28 of section: A a belt Wheell 33 and have shown on the shaft of'the roller 26 of section B afly wheel 34:; Powermay be applied to the band wheel 33' and it will be obvious that by this means, power may be transmitted tothe several rollers and belts and that the belts will move in opposite directions.
The purpose of the pin 32 in the plate 22 is to prevent the connecting rod from becoming locked on a dead center. It will be noticed that thewrist pins or cranks 29 of the gear wheels 27 are disposed. in angu= lar relation to each other and that they rotate in opposite directions so that as one of the gear wheels is moving in a clockwise direction, the other gear wheel will be moving in a counter-clockwise direction. Now as the crank pins 29 near a position where the connecting rod will be on a deadcenter, one or the other walls of the slot 31 will engage with the pin 32 and will rock upon this pin acting as a lever to shift the driven crank pin 29' past its dead center. At one extremity of movement of theconnecting rod the upper wall of the slot 31 will engage this pin and at the other extremity of its movement the other wall of the slot will engage the pin. By this means I drive one of the gears 27 from the other gear wheel 27 without the use of a train of gear wheels or other complicated mechanism and by this means I secure an opposite movement of rotation for the two rollers 26.
Mounted upon one of the trucks is a wind less 35 over-which passes a cable 36 which engages withthe end of the opposite frame. Now when this windless 35 is rotated to wind up the cable 36, assuming that the frames A and B are free or disconnected from the form, then the wheels 16 will be brought nearer to each other, the sections A and B will rotate on their pivotal con nections 1'4: and] 14 and the middle of the sections will, of course, rise. By this means when the form has been filled up to the openings 12, the frames A and B may be shifted nearer to each other and the middle portions of the frames elevated and thusby gradually elevating: the: middle of theframes A and B, the elevator belts will be raised. and thus discharge the straw or hay at higher and higher points into the form;
,When the form is completely filled, the
frame may be raised sufliciently to permit it to: shift it away from the form; and then the sections of theform may bedisconnected:
from each other and the form taken ofii of the stack or the: sections of the: form may be released fronr engagement with each:
other. when the frame sections A and B have been lifted to their highest point.
Supporting yokes 37 are adapted: to be disposed. upon: and rest onthe reaches composed of the sections 19' and 20; these yokes being downwardly bowed and adapted to receivvei the states-or sections of the form 10 when the form is disassembled and is to be transported from one place to: another. When it is desired to build a new stack, the form is again setup within. the frame in the position illustrated in Figs 1, and the operation again performed, Inasmuch as the reaches 19 and 20' are pivotally connected to the frame and are likewise slidably' connected to each other, it is obvious that these reaches may be adjusted to suit the degree of angularity between the sections A and B.
It will also be necessary, of-course, when the angu larity of the sections A and B is changed to remove the connecting rod 39 previously used and substitute therefor a shorter connecting rod. This, of course, necessitates the elevation of the frame sections A- and B in two or more stages, there This is particularly important at the present time when the art of building stacks of this character is gradually going into disuse for lack of trained labor. The form may be readily transported from place to place on the wheeled sections A and B and the form may be readily set up or taken down.
While I have illustrated a form of my invention which I have found to be thoroughly effective in practice, it will be obvious that many changes may be made in the form, without departing from the spirit of the invention, as defined in the appended claims.
Having described my invention, what I claim and desire to secure by Letters Patent is 1. A. stack former of the character de scribed including a form open at its upper and lower ends and designed to rest upon the ground, a frame coacting therewith including two sections pivotally connected to each other at their inner ends, said conjoined ends of the two sections embracing said form and the two sections converging upwardly, and means mounted on the sections for conveying material upward on said sections and discharging it into the upper end of the form.
