ARTHUR MARVIN, OF PANOLA, ILLINOIS.
CONVEYER-TRUCK- Specificationof Letters Patent.
Patented June 18, 1907.
Application filed September 20, 1906. Serial No. 335,454.
To 00M whom it may concern Be it known that I, ARTHUR MARVIN, a citizen of the United States, residing at Panola, in the county of VVoodford and State of Illinois, have invented a new and useful Con veyer-Truck, of which the following is a specification.
This invention has relation to conveyer. trucks and it consists in the novel construction and arrangement of its parts as hereinafter shown and described.
I The object of the invention is to provide a truck especially adapted for transporting i conveyers used in connection with corn shellers.
Thetruck consists, primarily, of a pair of wheel mounted axles connected together by cross rods. Bolsters are pivoted upon said axle and are connected together by a sill. Davits are mounted upon the bolsters and are located at one side of the sills. The sill extends for some distance beyond the rear bolster and is braced by truss rods and studs, the said studs being mounted upon the sill and the truss rods connecting at their forward ends with the forwardbolster and engaging the said studs. The davits are suitably guyed, but the parts are so arranged as to afford plenty of room behind the rear davit to swing the conveyer around in loading and unloading. The sill is provided at intervals with yokes which are adapted to prevent the conveyer from jarring off the truck while in transit.
In the accompanying drawing, Figure 1 is a side elevation of the truck, and Fig. 2 is a top plan view of the front end of the same.
The truck comprises the axle 1 and axle 2, both of which are wheel mounted and which are connected together by the cross rods 3, 3. The bolster 4 is pivoted to the axle l and the bolster 5 is pivoted to the axle 2. Each of said bolsters is provided with a davit 6 and each said davit is maintained in an upright position by guys 7. Each davit is provided with a winding mechanism 8, tackle 9 and conveyer receiver loop 10. The sill 11 is attached to the bolsters 4 and 5 and projects for some distance in the rear of the said bolster 5. The upper surface of the said sill is provided with yokes 12 spaced at intervals apart and upon which the conve er 13 is adapted to rest, the end portion of the said yoke retaining the conveyer upon the truck and preventing the same from jarring off while in transit. The studs 14 are attached to the sides of the sill 11 near the rear end thereof, the studs 15 being attached to the sides of the sill 11 over the rear bolster 5. The said studs 14: and 15 project above the upper surface of the said sill. The studs 16 are attached to the sides of the sill 11 at a point between the bolsters 4 and 5, the said studs 16 projecting below the lower surface of the said sill. The truss rods 17 are attached at their forward ends to the bolster 4 and engage the lower ends of the studs 16, then pass up over the upper ends of the studs 15 and 14 and are attached to the latter. The said truss rods are provided at points intermediate from their ends with suitable turn buckles, as 18. f
From the foregoing description, it is obvious that when the truss rods 17 are main tained taut, the rear end of the sill 11 is prevented from sagging, also the interme-' diate portion of the sill, between the bolsters, is prevented from going down under the weight of the load. In view of the fact that the guys 7 of the rear davit 6 are located one over the bolster 5, and another in advance of the same, sufficient clearing space is afiorded at the rear end of the truck for swinging the conveyer around after the same has been elevated.
Additional brace means is also provided for the sill 11, which consists of the truss rods 18, attached at their outer ends to the studs 19 and passing over the studs 20 and connecting with the studs 15. The braces 21, 21 are attached at their inner ends to the sides of the sill 11,- and at their outer ends to the bolsters 4 and 5 respectively. The'braces 22, 22 are attached to the under side of the sill 11 and connect with the pivot bolts of axles 1 and 2 respectively.
Having described my invention, what I claim and desire to secure by Letters Patent 1s:-
1 A truck comprising wheel mounted axles, bolsters located upon said axles, a sill connecting said bolsters together and projecting at its rear end beyond the rear bolster, davits mounted upon the bolsters, guys bracing the davits, the guys of the rear davit being located above the rear bolster and in advance of the same.
2. A truck comprising wheel mounted axles, bolsters attached to said axles, a siliconnecting said bolsters together, and yokes having upwardly extending ends arranged at intervals along said sill.
3. Atruck comprising wheel mounted axles,
bolsters attached thereto, a sill connecting said bolsters together, and truss rods fixed at one end above the sill and at their other ends below the sill and studs interposed between the truss rods and the sill.
A. A truck comprising wheel mounted axles, bolsters attached thereto, a sill connecting said bolsters together and projecting at its end beyond a bolster, studs attached to the IQ sill above thelast said bolster, studs attached to the projected end of the sill, studs attached to the sill at a point intermediate of said bolsters, and a truss rod attached to the forward bolster and engaging said studs.
In testimony that I claim the foregoing as I 5 my own, I have hereto affixed my signature in the presence of two witnesses.
