TRUCK.

Specification of-Letters Patent.

Patented April 30, 1907.

Application filed November 1,1906. Serial No. 341,644.

To all whom it may concern:

Be it known that we, CHARLIE AUGUs'r BRUST and JOSHUA H. DU Bosn, citizens of the United States, residing at Memphis, in the county of Shelby and State of Tennessee, have invented certain new and useful Improvements in Trucks; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to trucks.

As is well known, the saw cylinders of cotton seed linters and cotton gins have fre quently to be removed for the purpose of sharpening the saws. This procedure necessitates the bodily detachment of the breast of the machine in order to clear the cylinder of obstructing parts, and as the breast is very heavy and has to be handled by a num ber of workmen, much labor and loss of time necessarily attends the operation, aside from the danger of injury both to the saws and to the attendants. The removal of the saw cylinder is also attended with the above and even more formidable difiiculties as the cylinder is heavy and being arranged in a confined space there is great labor involved in detaching it from the linter or gin and also reat liability of injury to the workmen.

It is the object of the present invention, in a ready and practical manner, to obviate the objectionable features above enumerated and to render it possible for one operator with safety and ease, to transfer a saw cylinder from a linter or gin to a filing machine and return it to its operative position.

WVith the above and other objects in view, as will appear as the nature of the invention is better understood, the same consists in the novel construction and combination of parts of a truck for handling the saw cylinders of cotton seed linters and cotton gins, as will be hereinafter fully described and claimed.

In the accompanying drawings forming a part of this specification, and in which like characters of reference indicate corresponding parts ,-Figure 1 is a view in the nature of a diagram, exhibiting the frameworks of a linter and of a filing machine, and displaying certain attachments applied to such frameworks to eoact with the truck in securing the objects of the invention; Fig. 2 is a perspective detail view of the truck; Figs. 3 and 4 are perspective detail views of certain at tachments applied to the linter and saw filing machine and Fig. 5 is a perspective view of one of the elements of the apparatus.

Referring to the drawings A designates the framework of a linter or gin and B the like part of a saw filing machine. These parts may be of the usual or any preferred construetion and detail illustration is therefore omitted.

The truck, which constitutes the essential feature of the present invention, and is here in shown in its simplest and generally preferred form, comprises two side or base beams 1 and 2 that are secured, in any pre ferred manner to the intermediate portions of two end uprights or wheel supports 3 that are stayed against any tendency to yield to pressure by inclined braces & rigidly secured to the uprights and to the inner sides of the base beams. The intermediate portion of the truck is supported on wheels 5 carried by an axle 6 suitably assembled with the base beams, while the ends of the truck are supported by wheels 7 disposed, in this instance, in recesses 8 formed in the lower ends of the uprights 3, and rotate with or on axles 9 extending through the uprights and intersecting the recesses. As will be noted by reference to Fig. 2 the peripheries of the wheels 5 project below those of the wheels 7, when the truck is in operative position, thereby to permit the latter to be slightly rocked or canted when desired.

The upper end of each upright is provided about midway of its width with a seat or depression 10 to receive an end 0 of the axle of the saw cylinder, and adjacent to each seat is a stud or stop 11, the two operating to prevent the cylinder from rolling off the uprights when transferred thereto either from the linter or from the filing machine, as will hereinafter more fully appear. Each upright is further provided with a keeper 12 securely bolted at its outer side adjacent to one edge, and through each keeper extends a pin or rest 13.that projects into the upright.

In conjunction with the uprights there is employed two cylinder-lifting and transmitting skids 14, each of which is provided with a curved terminal 15 to constitute an inclined plane and with a transversely-disposed fulcrum pin 16 located adjacent to the curved terminal.

Secured to the cross beam at of the linter, adjacent to each of the journal boxes is a two-armed bracket 17, shown in detail in Fig.

3, each arm of which has a seat 18 to be engaged by the fulcrum pin 16 of a skid, thereby to hold the latter against slipping in use.

The cross beam of the filing machine, which latter may be of any preferred construction, has secured or adjacent to its ends, two hangers 19, shown in detail in Fig. 4, (one only being shown), each of which is provided with a slot 20 to be engaged by the curved end of a skid 14, when the cylinder 0 is being positioned in the brackets b of the saw filing machine.

en a saw cylinder is to be lifted from the linter and transferred to the saw filing machine, the cap squares c of the journal boxes 0 are removed, the feed board of the linter is raised and secured against dropping, the dash board or float box is removed and the breast is raised and held in the position shown in Fig. 1 in any preferred manner as bya block and tackle D. The curved ends of the skids are then inserted beneath the cylinder axle with the curves upward, and the fulcrum pins are brought into engagement with the seats 18 of the brackets. The truck is now moved in front of the linter, and upon the skids being depressed and disposed between the keepers, the former will occupy a horizontal plane, so that the cylinder shaft may be readily rolled upon the skids to permit its ends to engage the seats 10 in the uprights. The skids are now removed and the truck rolled to the filing machine, whereupon the hooked ends of the skids are engaged with the slots 20 of the hangers, and with the keepers 12, whereupon the cylinder may be rolled onto the frame of the filing machine with its shaft ends in engagement with the brackets b. When the saw has been shar ened, the operations above described are] to its under side and at reversed and the saw cylinder is again assembled with the linter.

It will be seen from the foregoing description that although the improvements herein are simple in character, they will be thoroughly efiective for the purpose deslgned, and may be adapted for use in connection with linters and saw filing machines already in use merely by employing the brackets 17 in connection with the linter and hangers 19 in connection with the filing machine.

Having thus. described our invention, what we claim as new and desire to secure by Letters-Patent, is

1. A truck comprising a wheeled supporting frame embodying uprights, each provided in its upper end with a seat, a stop disposed adjacent to each seat, and a keeper carried by each upright.

2, A truck comprising a wheeled supporting frame embodying uprights, each provided in its upper end with a seat, a stop disposed adjacent each seat, a keeper carried by each upright, and skids to engage the keepers in directing the axled ends of a saw cylinder to the seats.

3. A truck comprising a wheeled supporting frame embodying uprights, 'each provided in its upper end with a seat, a stop disposed adjacent to each seat, a keeper carried by each upright, and skids to engage the keepers in directing the axle ends of a saw cylinder to the seats, said skids being each provided with a curved terminal.

In testimony whereof we have hereunto set our hands in presence of two subscribing witnesses.
