IMPROVEMENT IN APPARATUS FoR PAINTING WIRE-CLOTH.

Specification forming part of Letters Patent No.

149,843, dated April 21, 1874; application tiled March 3, 1874.

To all whom 'it may concern:

Beit knownthat I, J osrnn H. DE WITT, of Orange, Essex county, New Jersey, have in vented certain Improvements in Painting Wire- Cloth, and in the machinery for printing tigures upon the same, of which the following is a speciiication:

My invention relates to an arrangement of felt-covered rolls for painting wire-cloth, with means for supplying the same with paint, a figured roll in combination with others, and a blast-pipe interposed between these painting devices and a dryingmachine, patented by me September 30, 1873. Y

The nature of my invention will be understood by reference to the accompanying drawings, in which- Figure l is the painting-machine, arranged to apply either a plain tint to the cloth by the rolls E and G, or to print a figure upon the same by the rolls F and H. Fig. 2 is the drying-machine, patented by me September 30, 1873. ln this, a heated chamber, B, contains driving-rolls'J, to carry belts and slats L for transporting the wire-cloth W to a reel at the other end, where it is wound up dry. Fig. 3 is a plan of the paint-reservoir; Fig. 4, a direct end view ofthe printing-roll F. Fig. 5 is a side View of the roll E, and the means for moving the reservoir S. Fig. 6 is half in section and half an outside enlarged view of the printing-roll F.

The operation ot' the machine is as follows: The rolls D E F G H, as well as the roll Y, are supported on the frame Z, and provided with suitable adjustments, so that they may be pressed together or set apart, as shown at E and G. The rolls D, E, G, and Hare made of wood, to which is tacked a coating of cloth or felt. This absorbs the paint sufficiently to distribute it wherever it is wanted, or,l as in the case of H, to furnish an elastic support to J:he wire-cloth W when printed by the press ure upon it of the printing-roll F. This last roll is made in a peculiar manner, and is shown in detail in Figs. 4 and 6. It is made of wood, bored to slip onto a wrought-iron shaft, upon which it is secured by a nut I, Fig. 6. The tigure upon the roll is formed by letting narrow strips of brass edgewise into the wood, and forcing` felt, cut into the proper figure,

into the spaces between the projecting strips andV impresses it upon the. cloth W in the proper ligure, when the same is passed between it and the suliporting-roll H, which, being upon the under side ofthe dry cloth, receives no paint, and makes no impression upon the wire-cloth.

The machine is supplied with paint, either for painting or printing, by thereservoir S, which is a box perforated at the bottom to throw the paint upon the roll E, and supported at each end by slides V, which enable it to slide back and forth, as it is impelled by the pin U acting against the cam C on the end ot' the roll E. This sliding movement of the reservoir distributes the paint equally over the felted surface of the roll E, which, for the printing operation, conveys it by contact to D, and thence to the printingroll F.

To control the flow of paint from the reservoir, an attendant supplies but a small amount at a time, as it may be needed, from a pitcher.

It will be perceived that the reservoir S is not designed as a supply-chamber, in which `any great quantity of paint is stored for use, but that it acts solely as a means of distribut` ing the paint upon the roll E, the supply being kept up by an attendant, who graduates the amount placed in the trough for distribution by the amount appearing on the wire-cloth, where excess would be very detrimental. 1t the trough were filled with paint there would vbe no way of checking or regulating the iow until it all was discharged.

The slides V, upon which the reservoir vibrates back and forth, are simply short rods extending from each end of the reservoir, and working loosely in holes prepared in the top of the stands or frame Z. The pin U projects from the bottom of the reservoir and engages with the cam C, secured on the end of the roll E.

- When this machine is used for painting plain tints upon the cloth W, the roll D is removed, the rolls F and H are separated about two inches, and, the rolls E and G being brought in contact, the paint covers them both, and the wire-cloth being drawn between them is painted upon both sides.

It will be seenl from the above description of brass. This felt readily absorbs the paint,

that the painting-machine is constructed to do two kinds of work, which have generally been done in two different machines, and that by the adjustment of the rolls E and G, or F and H, the machine can be readily adapted toA plain painting, or the production of iigures v upon wire-cloth.

of the wire-cloth W, the top of the pipe M is,

formed with a T-head, A, long enough to reach across the cloth.

I am aware that a blasthas already been used in combination with a reel of wire-cloth to dry the same after painting, and I therefore expressly disclaim any right to such a combination, restricting myself solely to the interposing of a blast-pipe between the painting and drying machines patented by me, for the purpose of removing obstructions that occasionally fill the meshes.

In Fig. 5 the paint is shown running from the holes in the reservoir S upon the roll E at T.

Instead of the straight lines shown at T, the paint will naturallyY take a zigzag course upon the roll, derived from the motion of S.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

l. In combination with the painting machine, Fig. l, and the drying-machine, Fig. 2, the interposed blast-pipe M, arranged substantially as and for the purpose described.

f 2. The combination of the printing-roll F (with the figure constructed of felt and metal strips, as described, upon a cylindrical surface of wood) with a supporting-roll, H, and Wirecloth W, for printing iigures upon the cloth, substantially as shown and described.

3. The reservoir S, cam C, and rolls E and G, made of Wood, with a felt or cloth surface, for painting wire-cloth, substantially as shown and described.

4. The machine for painting plain [ints or iigures upon wire-cloth, constructed substantially as shown and described, with the reservoir S, wooden rolls D, E, Gr, and H, covered with cloth or felt, and the printing-roll F, with the figure constructed of felt and metal strips, as described, upon a cylindrical surface of wood.
