IMPROVEMENT IN WORKING IN SHEET IVIETAL.

Specilieaton forming part of Letters Patent No. RAJSS, dated April .'22, 1856.

To @ZZ who/lt it may concer/t.-

Beit known that we, SAMUEL R. Snnrn'nn and ORSON V. STOW, of Plantsville, in lthe county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Machines used in the BIanufaeture of rIinware, for Yiring, Beading, rife.; and we do hereby declare that the following is a full, clear, and exact description of the'same, ret`- erence being had to the annexed drawings, making a part of this specification, in which- Figure l is an end View ot' a wiring-machine with our improvements applied to it. Fig. 2 is a side view of the working parts ot" the same, the frame being bisected vertically, and also the adjustable rotating guide.

Similar letters of reference indicate corresponding parts in both figures.

Our invention consists in the employment or use of an adjustable rotating guide, which is placed on one of the rollers of the machine, as will be presently shown and described, whereby the box, kettle, or other article being operated upon will be fed through the ma chine without the aid of the operator.

To enable those skilled in the art to fully understand and construct our invention, we will proceed to describe it.

A represents a framing, which may be eony structed of cast-iron, and is ot' the usual construction, the upper part, d, ot' the frame being jointed to the lower part, I), at c, and the upper part, u, having a shaft, B, itted within it, and the lower part, b, having a shaft, C, tt ted within it.

D represents a spring attached to the upper surface ot' the part n. ot' the framing. The outer end of this spring bears upon a projection, j', on the upper part ot' a guide-frame, E, in which the upper part, a., of the framing is iitted.

F represents a screw by which the upper part, a, of the framing is forced down toward the lower part, Z).

To the end of each of the shafts B C there is att-ached a metalic roller, G.

rlhe above parts are all ot" the usual construction, and therefore do not require a mi nute description.

rIhe rollers represented in the drawings have lips g on their outer edges, as shown clearly in Fig. 9 'These rollers, thus formed,

are used for wiring the rims or edges of sheetmetal vessels-such as pails, coal-hods, &e. The lips g of the rollers, as the rollers rotate, bend the sheet metal or close it around the wire, the vessel and wire being passed between the rollers, as shown in red in both figures, h representing the wire and the sheet metal.

H represents a gnidewhich is fitted over the lower roller, G, and a portion o'l` the shaft C. The guideII may be described as being of cylindrical form, so as to correspond with the shaft C and roller G, and vtit snugly on them, as shown clearly in Fig. 2. The lower shaft, C, has a screw-thread,j, cut upon it, on which a nut, I, is fitted, and a spiral spring, J, is titted around the shaft C within the guide. By turning the nut I the ou ter edge of the guide II may be moved nearer to or farther from the lip f/ on the lower roller,as will be readily seen by referring to Fig. 2, the nut I, when turned in one direction, forcing the guide I-I outward or toward the lip g on said roller, and when the nut I is turned .in the opposite direction the guide is thrown back vfrom said lip by the spring J. rIhe edge ot' the article being wired of course rests or bears against the edge of the guide H, and the guide must be adjusted aecording to the thickness of the wire used, as the wire must tit between the lip r/ on the roller and the edge of the guide;

By the above inqnovement the vessel or othelI article being wired will be fed through or passed around by the pressure ofthe rollers and guide ll, as the guiderotates with the lower roller. No force or aid will be required from the operator. In the machines used at present the guide is stationary or fixed, and is attached tothe framing ot' the machine, and so much friction is created thereby that the operator is obliged to force the article around between the rollers as they rotate.

K represents a forming-roller, which is fitted on an axis, L, attached at a rightangle with one end of an arm, M, which is fitted on the end of the upper shaft, B. The opposite end ot' the arm M has a slot, It', made through it, through which slot a set-`screw, N, passes into the framing A. By means ofthe set-screw the roller Ii may be secured in a higher or lower position, so as to curve the sheet metal as it is passed between the rollers. As the roller is attached to the upper shaft, B, it will be seen that the roller rises with it und the metal The adjustable rotating` guide Il, attached 1s relieved at onee of its pressure as soon us to either el" the rollers G, constructed and arthe upper. roller, G, is raised. ranged substantiallyas described, for the pur- The forming-roller K is now used on nm-V pose specified. chimes; but it requires :t separate adjustment in order to be raised from the metal or nrtiele SAMUEL R' SHEPARD' ,r .7 between the rollers G G.
