ELECTROPLATING-HOOK.

SPECIFICATION forming part of Letters IPatent No. 579,124, dated March 23, 1897.

Application filed p l 2 5, 1 8 9 6.

To all whom it WI/Cbfl/ concern:

Be it known that I, JOHN BOssARD, a citizen of the United States, residing at D 1110 u que,

in the county of Dubuque and State of Iowa, have invented certain new and useful Improvements in Electroplating-Hooks; 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.

My invention relates to electrodepositing devices in which the articles to be deposited upon travel around in or are drawn through the plating-bath by mechanical means and receive the deposit similar to that described in Letters Patent granted to me on the 23d day of July, 1895, and numbered 542,986. It has special reference to the means of suspend ing the articles in the bath while they are be ing carried therethrough; and it essentially consists in the novel suspension-hooks with other appliances, whereby the articles which are attached to the hooks are mechanically revolved or partially turned as they are drawn through the bath to avoid what is known as shading, and to make more even the deposit on all parts of the articles of Whatever shape.

In explaining my device it will be necessary to refer to certain drawings, which form a part hereof, and in which Figure 1 is a plan of a segment of the cathode strip and a clamp fastened upon it and a section of the body of the hook of one form. Fig. 2 is a segment of a cathode strip and deflecting-clamp in plan view, and also shows pin upon the clamp and arm of the hook, shown partially in section and partially in side elevation. Fig. 3 shows sections of the body of the hooks of different forms. Fig. 4 is a front view of a broken portion of a circular carrier, a cathode-plate, rail, and post for supporting the cathode plate and a view of the hook suspended from the carrier, showing mode of revolving same. Fig. 5 shows a side View of the body of hook of one form and section of wheel on shank of hook. Fig. 6 is a plan view of a wheel to be attached to the body of the hook. Fig. 7 is a modification of Fig. 6. Fig. 8 shows a modification of the cathode strip and means for operating the wheel shown in Fig. 7. Fig. 9 shows a sec- Serial No. 589,132. (No model.)

tional view of the bridge from which the articles are suspended with a side elevation of the hook and the endless chain for advancing the articles through the bath with a sectional view of the cathode strip or bars. Fig. 10 shows a side elevation,with part broken away, of a longitudinal tank with which my device may be used, a sectional View of which is shown in Fig. 9.

Like letters of reference denote correspondings parts in all of the drawings.

A represents the body of my improved hook, which is made of copper or other electrical conducting material, and is somewhat enlarged at the center and made of various shapes for purposes hereinafter described. The upper end is formed into a head a, for the purpose of loosely swiveling it to the hooked portion B, as shown in Figs. 4, 9, and 10. The lower portion b terminates in any convenient shape or size to allow readily the securing thereto of the hook O by linking, soldering, or other convenient methods, or the articles may be wired directly to the lower end of said body. This hook,above described, when used with my Patent No. 54:2,986, is suspended from a bridge D, a section of which is shown in Fig. 9 and a side elevation in Fig. 10, and rests against a cathode strip (1, from which strip it receives the cathode-current. There is also attached to this strip (1 one or more clamps E or F, as shown in Figs. 1 and 2, and there may also be, for certain purposes hereinafter explained, pins e, (shown in Figs. 4i and 10,) secured to said cathode strip d.

In Fig. 10 there is shown a longitudinal tank similar to that shown in my Patent No. 542,986, in which the points of the hooks B protrude through the links of the endless chain R and rest on the top of the rigid bridge D. The tank S is supplied with the usual anodes T, suspended from the sides of the tank. There is also secured along the side of the tank the cathode strip (Z, to which the clamps E and G and the pins 6 are attached.

lower end of the body, and in this instance the body of the hook may have the shape of X or Y, (shown in section in Fig. These hooks so formed with the articles attached to them are suspended from the top of the carrier or bridge D, as shown in Figs. at, 9, and 10, with the bodies X or Y of the hooks B bearing against the cathode strip (Z. As the hook is drawn along the bridge D by the endless chain R, as shown in Figs. 9 and 10, or travels with the circular carrier F (shown in Fig. 4) the bodies Y or X will pass along, bearing against the cathode strip 0?, up the incline of the clamp E, and on reaching the abrupt end of said clamp will drop suddenly against the body of the strip (1 and at the same time turn the article to be deposited upon partially around in the bath, stirring the bath to make it more active and at the same time bringing a different surface of the article to the anode influence. Again, if it is desired to partially turn or revolve the articles as they are drawn through the bath then there may be attached to the body A of the hook a wheel Z. (Shown in Fig. 6.)

A convenient mode of construction of the body of the hook and of the wheel is shown in Fig. 5, wherein the body A is formed in a square and the center of the wheel is also square, but the center of the wheel is a trifle larger than the body A to allow said wheel Z to readily slide up and down upon the body A for the purpose of adjusting itself upon the hook to the plane of the cathode strip d. As the hook is drawn along, by the endless chain R, the edge of the cathode strip 61 the spokes z of the wheel will impinge against the pins 6 on the strip 61, and in this manner partially rotate the articles in the bath, or if the oathode strip has a clamp secured thereto, as shown in Fig. 2, the spokes s will impinge against the pin f upon the clamp F, and also rotate the articles in the bath. It will be seen by this manner of turning the articles as they are carried through the bath that their entire surface will be exposed to the influence of the anode and will evenly receive the deposit,

and at the same time the bath will be agitated and kept active.

When it is desired to have the article to be deposited upon constantly turned in the solution, the edge of the cathode strip cl is formed into notches g, as shown in Fig. 8, and there is then attached to the body A of the hook the toothed wheel H. (Shown in Fig. 7 Then as the articles are drawn along the teeth upon the wheel H will engage with the notches g or teeth upon the strip cl and constantly turn the articles, and it will be seen by this mode of suspending the articles in the bath the deposit will be done evenly upon all of the surfaces and the bath will be constantly stirred and active.

It is manifest that various other forms may be given to the body A of the hook, adapted to the shape of the articles to be deposited upon, the thought being to so sustain the articles of whatever shape as they are drawn through the bath that all their parts will be equally exposed to the anode influence and evenly deposited upon and the bath at the same time kept ever active by the constant stirring of the same caused by these various movements of the articles as they are advan ced through the bath.

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

1. A hook of the character described, con sisting of a hooked upper portion for engaging with a carrier, a body swiveled to said hook, a lower portion from which the articles are suspended in the bath, means for causing the articles to be revolved while suspended from said hook in the bath and a carrier from which the hooks are suspended for advancing the articles along in the bath, as and for the purposes shown.
