METHOD OF MAKING ROLLERS FOR JUTE-SLIVERING MACHINES- SPECIFICATION forming part of Letters Patent No. 407,194, dated July 16, 1889.
Application filed September 10, 1888. Serial No. 284,977. (No model.)
To all whom it may concern.-
Be it known that I, HOWARD PRATT GAR- LAND, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented certain new and useful Improvements in the Mcthod'of Making Rollers for Jute-Slivering Machines; and I do hereby 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 an improved method or process of making,producing, or manufacturing wheels, disks, or rollers for use in machines for slivering jute and other like purposes.
It consists, essentially, first, in producing a series of comparatively small or narrow wedgeshaped sections or segments of wood formed in such a manner that the grain and fiber may run lengthwise of the sections, said sections being, when they are properly arranged in a circular manner, suificient in number and correct in outline and shape to form a complete wheel or disk; sec0nd,in intcrposing between anytwo adjacent wedge-shaped sections after the series have been arranged circularly in the clamping device for the purpose of being compressed together to form the wheel, or in inter-posing between the members of each of two or more pairs of adjacent sections one or 4 more extra sections above what may be necessary to constitute a complete wheel; third, in compressing these sections together to form the wheel or disk, the extra sections being by great pressure forced into the wheel, and thus a rigid, solid, and firm disk or roller produced whose fiber is about as compact as that of the original wood, and, furthermore, my improved method comprises certain detailsin the making of the wheel, substantially as will behere inafter described and claimed.
In proceeding to carry out my improvements and bring my method into practical effect I first provide a suitable apparatus or device for compressing and holding together the wedge-shaped sections in a circular form and arrangement and in such position that center plates or heads may be conveniently applied and secured on both sides of the wheel.
I have represented in the accompanying drawings one form of press-chuck or clamping apparatus,which may be used for the purpose herein indicated of compressing the segments or sections into the finished wheel. I am, however, not restricted to this form of apparatus, but show it by way of example only, and reserve the liberty of using any proper clamping machinery which may be found suitable and effective.
In the accon'ipanying drawings, Figure l is a plan or top vicw of the clamping-press with a number of blocks in place. Fig. 2 shows the same with the edges pressed up and the blocks compressed to form the circular wheel and ready to receive the heads or center plates. Fig. 3 is a side view of one of the wheels. Fig. l is a detail view of one of the wedge-shaped sections or segments of which the wheel is constructed. Fig. 5 is an edge view of the finished wheel. Fig. 6 is a similar edge view of the wheel in the condition shown in Fig. 3.
Similar letters of reference designate corresponding parts throughout the different figures.
In constructing jute wheels or rollers in accordance with the principles of my present method I first provide a number of wedgeshaped sections or segments. These are preferably made comparatively small or narrow. They are cut, sawed, or otherwise fashioned out of pieces of wood having a suitable thickness. They are so made that the fiber or grain of the wood will run lengthwise of the section, thus enabling the fiber to be presented endwisc to that edge of the section which is to form the acting or operating surface or rim of the completed wheel. By this construction the completed wheel will be best adapted to resist wear. A sufficient number of these sections will be made, when properly arranged in a circular manner, to complete a wheel or disk. It will be noted that these segments or sections will be in length equal to the radius of a circle circumscribing the finished wheel, and are quite narrow in proportion to their length, such form being observed, as has already been indicated, so that the fibers of the wood may conform as closely as possible to the radius of the circle of which the block is a segment.
considerably within wide limits without departing from the spirit of this invention. The
points of the wedging-sections will lie together at the center of the wheel. 'After I have thus produced a number of these wedging-sections sufiicient to form a complete circle when they are properly arranged, they are ready to go within a press such as I have represented in Figs. 1 and 2, (by way of example only, of
.course,) each one having been previously dipped in glue or other adhesive mixture. This press or clamping device, which I have shown in the drawings as suitable for use in pressing the blocks together and confining them while they are being bound together by the glue and while their heads are being applied to both sides of the completed wheel, is constructed with two jaws or dies D D-one movable and the other stationary-in a bedblock E. The movable partD is drawn away or moved toward the fixed part D by the screws F F, suitable gearing and ahand-wh eel H being employed to produce this movement. In practice the jaws are separated, as shown in Fig. 1, and the additional space between the two permits one or more segments over the number required to form the circle to be inserted.
The required number of segments to form a complete circle being now arranged in the press, the next step would naturally be to operate the latter and compress the segments to form the wheel. Before doing so, however, I interpose between any two adjacent sections an extra section-that is, one more than is required to form the circle. If desired, I may in terpose an extra section at more than one point in the series of sections, thus using several sections more than are necessary to form the wheel. In this use of one or more extra sections above what is required to make a complete wheel resides one of the most important features of my present improved method, because by crowding these extra sections into the body and substance of the wheel I make it firmer and more compact than would be possible if only the sections were used, which, when first arranged in-the press, seemed sufficient to make the wheel. The clamping press is now operated. If power is applied to a proper degree, the jaws will press all the blocks together and produce the desired circular shape. While the partially-finished wheel is in this position in the press the plates or heads B B are placed in the center on opposite sides and fastened by nails or screws Z. These heads are formed of pieces of stuif laid together with the grain of one disposed at right angles to that of the other. At the proper time the disk or blank thus formed is removed from the clamp and the rim and edge finished off in a lathe. The wheel is then given the form shown in Fig. 5, besides being turned off to a taper, and the rim faced to have the proper degree of thickness and smoothness.
A wheel or roller formed in this manner can be used until it is worn down to the head or center plates, as its edge can be trued and turned from time to time as often as it needs attention. Such a wheel will have greater durability and do its work better than one in which the body is formed of sections of considerable size.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. The herein-described improved method of making wheels or rollers for use in juteslivering and similar machines, consisting, essentially, in first producing a series of wedge-shaped sections or segments sufficient to form a complete wheel, then in interposing between any two adjacent sections an extra section, then in forcing the sections together, and finally securing the sections together, to form a complete wheel, substantially as described.
2. The herein-described improved method of making wheels, disks, or rollers for use in machines for slivering jute and like purposes, consisting, first, in providing a series of narrow wedge-shaped wooden sections having the grain or fiber lengthwise, said sections being sufficient to form a complete wheel, then in interposing between any two adjacent sections an extra section, then compressing all the sections firmly together, and finally securing the sections together, substantially as described.
In testimony whereof I afiix my signature in presence of two witnesses.
