ROVlNG-CAN.

SPECIFICATION forming part of Letters Patent No. 481,554, dated August 30, 1892.

Application filed April 25. 1892.

To all whom it may concern.-

Be it kn own that I, ALVAN B. FISHER, a citizen of the United States, residing at Rutland, in the county of Worcester and State of Massachusetts, have invented a new and useful Improved Roving-Can, of which the following, together with the accompanying drawings, is a specification sufficiently full, clear, and exact to enable persons skilled in the art to which this invention appertains to make and use the same.

The objects of my present invention are, first, to provide a strong, efficient, and durable roving-can for use in cotton factories, said roving-can beingformedof thin cross-laid wood veneers and having its ends protected and reinforced by metal borders; second, to provide in a roving-can cylinder formed of wood veneers a connecting-joint that will efficiently support and confine the abutting edges of the wood at the side of the cylinder and prevent the slivering or tearing out of the same; third, to provide a method of construction whereby roving-cans or cylinders can be formed of double-ply veneers in a practical, convenient, and economical manner and injurious internal stress in the finished product avoided. These objects I attain by the manufacture and method of production explained in the following description, the particular subjectmatter claimed being hereinafter definitely specified.

In the drawings, Figure l is a perspective view of my improved roving-can. Fig.2 is a horizontal section of the same. Fig. 3 is a vertical section through one side of the top end and its metal border. Fig. 4 is a vertical section through one side of the bottom end and its supporting-rim. Fig. 5 is a horizontal section, full size, of the connectingjoint for the side of the cylinder; and Fig. 6 is a diagram illustrative of the method of making the cylindrical body of double-ply wood veneers.

The cylinder or body a of my improved roving-can is formed of a wood fabric consisting of two plies of thin veneers a a firmly glued or cemented together with their grain cross-laid or extending in the respective plies in transverse direction to each other, the grain of the inner ply a running in a direction longitudinal of the cylinder, and the grain of the outer ply-ct running in the direction of the Serial No. 430.479. (Ilo model.)

circle or around the cylinder. The edges of this body fabric are best abutted and joined together at the side of the cylinder by a metal joint-plate Z), attached by rivets c and formed so as to cover and protect the edges of the wood veneers to prevent their slivering or catching the fibers of roving when the can is in use. Said joint-plate is preferably made, as indicated in Fig. 5, of a piece of sheet metal and having its edges folded back upon itself at 3 3, turned inward at their meeting line 4 between the abutting edges 5 of the body-cylinder a, and then turned back opposite each other and their respective edges 6 pressed down and firmly clinched onto the edges 5 of the double-veneer fabric, as indicated, thus reinforcing, supporting, and completely protecting the edges of thewood fabric and forming a very secure and efficient connection. The rivets o are arranged through the joint-plate near the folds 3 and at some distance from the edges 5 of the cylinderfabric, so that they are not liable to become loose or split out.

A metal reinforce border cl is arranged about the top of the can, (see Fig. 3,) having an edge 7-of suitable form to cover and protact the edge 8 of the body, to which the border is secured by rivets 9 along its lower edge.

The foot of the can is reinforced by a broad metal bandf and the supporting-rim it, that extends under and sustains the bottom 2 of the can, which is best formed of a circular disk of wood. (See Fig. 4.) The rim and bottom are fastened in place by screws or nails 10, as indicated. If in any instance desired, the bandfand rim it may be a single piece. Rivets in the border d and foot-band f pass through the joint-plate I), thus tying the top and bottomparts securely together.

My method of making the cylindrical body a of double-ply cross-laid veneers and producing a fabric ultimately free from objectionable internal stress and which will retain its cylindrical form with strength and elasticity is as follows: Wood veneers a and a about one-sixteenth inch in thickness are first out to desired form and size. The veneer a for the interior is then soaked in water and the veneer a for the exterior is used dry. Glue or cement is applied to one surface or to each of the veneers and the two plies are placed together with their grain in proper direction and the glued faces between them. The fabric is then put under strong pressure, which flattens the two plies together throughout their entire area, and the pressure is maintained thereon until the glue has become securely set but not thoroughly hardened. The fabric is then taken from the press and permitted to dry in a free and unconfined condition, and the shrinking of the inner ply a by its contracted action causes the fabric to curl or roll itself into a cylindrical form, so that when dry it will closely approximate to the form of the finished can. Consequently when squaring the edges and affixing thereto the joint-plate there is practically no tendency for the sides to spring apart, and after the can is completed and in use there is no objectionable internal stress tending to buckle or rough up the interior ply; but the normal tendency is to maintain its cylindrical shape against all opposing forces. Hence avery strong,light, and elastic body is produced that will not become permanently dented like sheet metal nor weaken like paper fabric When subjected to external concussions,

but which afiords a roving-can that is elastically rigid and practically indestructible under all normal exigencies of service. The interior of the can is smooth and coated with shellac or other hard varnish or any suit able smooth-coating material, so that it presents nothing that would interfere with the free running of the cotton roving or sliver into and from the can.

These cans can be made in the various sizes required in the factories, and can be used in similar manner and for such purposes as roving-cans are generally employed.

I claim as my invention herein, to be secured by Letters Patent 1. A roving-can provided with a cylindrical body made of double cross-laid wood veneers and having a metal joint connection overlying and binding the adjacent edges along the sides of the cylinder, with its outer edges riveted through the veneer fabric, its top end reinforced by an edge-protecting metal top border and its lower end protected by an underfianged metal foot-supporting rim, substantially as herein set forth.

2. The method of making double-ply woodveneer cylinders for roving-cans, which consists in gluing together a wet veneer and a dry veneer with their grain cross-laid, applying pressure to the same in substantially flat position until the glue has become set, and then removing the pressure and drying the product without confining it, and in a manner to facilitate the curling up of the edges, substantially as set forth.

3. The side-joint connection composed of a metal plate having its edges folded over upon itself, turned inward at their meetingline between the abutting edges of the cylinder and there bent back in opposite directions and pressed down upon the inner face of the respective edges of the cylindrical fabric, the outer folded parts of said joint-plate extending laterally beyond the width of its inner down pressed edges for supporting the cylindrical curve of the fabric, and connected through said fabric by rivets along the folded edges of the plate, in combination with the body-cylinder, substantially as shown and described.

4. The roving-can constructed as herein described, its cylindrical body a formed of crosslaid plies of wood veneer, having their abutting edges 5 connected and protected by a joint-plate that embraces and compresses said edges and reinforced at the top by a metal border that covers and protects the edge of the wood to prevent slivering of the same, the bottom disk z', the reinforce-bandf, and the metal foot-supporting rim h, surrounding the base of the body and extending beneath the same, all substantially as shown and described.

Witness my hand this 23d day of April, A. D. 1892.
