STAUlEG-FURMING TRUCK.
Application filed September 10, 1921.
To all to 7mm it may concern Be it known that l, PHEOLA J. Parson, a citizen of the United States, residing at Arnold, in the county of lless and State of Kansas, have invented certain new and useful Improvements Trucks, of which the following is a specification, reference being bad to the accompanying drawings.
This invention relates to stack formers, particularly to that type adapted to trail along beside a harvester such as a header or the like, and has for its object the provision of a novel truck device which carries a rack within which the grain is deposited for forming thestack, this'truck being provided with means whereby the completed stack may be moved off and deposited upon the ground at the desired location.
an important object is the provision of a device of this character which is provided with novel power operated means for moving the completed stack off of the truck, this means being operable at will.
Another object is the provision of a truck device of this character which is provided with peculiar means whereby the stack movs ihg member may be thrown into and out of gear so as to permit turning of the device at the end of a row.
A further object is the provision of novel means whereby the movable floor or bottom which. supports the stack as it is formed may be swung downwardly to permitmow ing off of the stack and swung upwardly to be again disposed in receiving position, novel brace means being furthermore provided for holding the movable floor in its normal or elevated position.
i-lrn additional object is the provision of a device of this character which will be comparatively simple and inexpensive in construction, easy to operate, highly efiicient in action, durable in service and a general improvement in the art.
With the above and other objects and ad vantagesin view, the invention consists .in the details of construction to be hereinafter more fully described and claimed, and illus trated in the accompanying drawings, in which:
Figure 1 is a plan view of the device;
Figure Q is a side elevation thereof;
Figure is a cross sectional view talren through the front axle;
in StaclcFormin g Serial No. 199,808.
Figure 4. is a longitudinal sectional view; Figure 5 is a rear View; Figures 6, 7 and 8 are detail views. R-e ferrlng more particularly to the drawings, lhave shown my device as comprising an elongated rectangular open frame 10 which may be formed of suitable timbers or angle iron of any preferred cross sectional which carries wheels l l which are of considerably greater diameter than the wheels 11 so that the frame will be always rearwardly and downwardly inclined. The front axle 13 has the usual tongue 15 connected therewith and the usual hounds or braces 16. Carried by the front wheels are gears 17 for a purpose to be described.
Disposed within the rectangular frame 10 is a movable floor or bottom 18 which has its rear end extending beyond the frame 10 and which has its forward end pivotally mounted upon shafts 19 which are journaled through or upon the sides of the frame 10. Located upon these shafts are sprockets 20 about which are trained chains 21 which extend longitudinally around the floor 18 and which are trained about guide rollers or sprockets 22 at the rear end of the floor. These chains 21 are connected by an endless apron 23 which may or may not be provided with slats as preferred. Con nected with the outer ends of the shafts 19 by universal joints 24. are swingingly mounted shafts 25 which carry gears 26 adapted to be brought into mesh with the gears 17 associated with the front wheels for the purpose of effecting rotation of the shafls'lt) for driving the conveyor apron when desired.
Mounted upon the rear ends of the side bars of the frame 10 are upwardly extending brackets 27 which are slotted and which have their inner edges formed as racks 28. Journaled upon the floor 18 are pinions 29 meshing with these racks and carrying handles 30 whereby they may be rotated for the purpose of raising or lowering the floor 18 with respect to the frame.
In order to provide means for rigidly supporting the floor 18 in its normal or horizontal position, I provide a plurality of braces 31 which are hinged with respect to the floor and which have their lower ends formed as angular feet 32engageable upon the side bars of the frame 10. All these braces are connected by a longitudinal rod 33 whereby all the braces may be swung simultaneously out of engagement with the frame for permitting the floor 18 to be lowered by the rack and pinion mechanism above described.
The numeral 34 designates the stack forming rack which'is mounted upon the frame 10 and which extends upwardly to any desired height and which has its rear end provided with a gate 35 which may be opened when it is desired to deposit a formed stack upon the ground.
Mounted upon the front end ofthis rack isa suitable seat 36 for the operator and associated with this seat ispreferably provided a foot rest 37. Secured at the front end of the frame or upon a bolster which might be interposed between the frame and the axle, are'segmental racks 88 with which are associated pivoted levers 39 extending upwardly at opposite sides of the seat within convenient reach of the operator. Movably mounted upon the sides of the frame by means of bolts 40 engaging in slots 40" formed therein are brackets 410 which are connected with the levers 39 by a link and angle lever connection designated broadly by the numeral tl, and which are provided with bearing slots d2 for the jointed shafts.
25. The slots 40 and d2 of the brackets 40 diverge and by reason of this divergence, when the brackets 40 are moved rea-rwardly upon the frame the shafts 25 are elevated the racks 28 and therods 33 are mov d to swing the braces 31 into engagement with the sides of the frame 10. When pressure upon the pinions 29 is relieved, the weight of the floor and associated partswill hold the braces 31 in position so that the floor will be rigidly supported and be capable of sustaining greatweight. The device drawn along the side of the harvester, header or other similar mechanism and grain from the latter is deposited within theraclr 34.
Assuming that the stack has been formed, when. it is desired to remove it from the device, it is necessary to open the gate 35 in the rack and to set the conveyuir apron in motion. Before setting the conveyor in motion it is, however, necessary to move the rods so as to release the ln'accs 31 from engagement with the frame and this may be easily accomplished if the pin ions 29 are rotated slightly to elevate the floor a suilicient extent to relieve the strain upon the braces. The floor is then allowed to descend to its lowermost position and its rear end will almost touch the ground. The operator then moves the lovers 3%) in the proper direction to move the brackets 40 so as to swing the jointed shafts :25 downwardly for bringing the gears 2o into mesh with the gears 17, after which the lovers are locked by mcans of the usual grip released pawl mechanism cooperating withthe segments 38. \Vhen the device is then driven, the gears 26 will be driven and this will result in driving of the sprockets 20 and consequent rearward movement of the conveyor apron 2? which will causc the entire stack to pass rearwardly on to the ground. The parts of the truck arc hen returned to initial position and the dc vice is then again ready for use in forming another stack.
From the foregoing dcsm-iption and a study of the drawings it will be apparent that l have thus provided a colnparativel v simple and inexpensive truck which is well adapted for use in forming stacks of grain as the latter is cut or harvested, eiiicicnt means being provided whereby the finished stacks may be deposited upon the ground in a rapid manner and by tl i application of power derived from pulling the device over the ground. Owing to the gradual d wnward. and rearward incline of the frame and floor, when, the latter is in lowered position. it will be apparent that there is no likelihood of upsetting the stack when depositing it on the ground. It is also to be noted that the novel mcans for throwing the conveyor device into and out of operation permits the device to he tl'irown into war very easily when dumping or union 1g of the stack desired, the gear 11' hanism being normally inactive so as not to interfere with the necessary turning action or any irregularities in the move ment of the front wheels while the device is being loaded. Another noticcablc feature is the provision of the novcl brmring n|cchaa which supports the movable floor in horizontal position and with such rigidity that it s capable of sustaining a heavy weight without danger o f hrcalcagc of any of the parts.
While I have shown and described the preferred emlgiodiment of the invention. it of course to be readily undcrstoml that reserve the right to make such changes form, construction and arrangement l (ill of parts as will not depart from the spirit of the invention or the scope of the sub joined claims.
