ELECTROPLATING DEVICE.

Specification of Letters Patent.

Patented Aug. 8, 1905.

Application filed September 17, 1904:. Serial No 224,833.

To all whom it may concern:

Be it known that I, HENRY SGHUESSLER, a citizen of the United States, residingat Peru, in the county of Lasalle and State of Illinois, have invented new and useful Improvements in Electroplating Devices, of which the following is a'specification.

This invention relates to electroplating devices designed especially for coating sheetmetal plates with a metal electrically deposited, and has for its objects to produce a comparatively simple device of this character wherein the plates under treatment will be maintained in a substantially horizontal position, thereby obviating buckling of the plates and insuring a uniform depositing of the plating material thereon and at the same time obviating contact of the plate with the electrical anode contained within the tank.

A further object of the invention is to provide a tank of such form that the amount of solution employed therein will be reduced to a minimum and one wherein the plates to be treated may be readily introduced into the solution.

To these ends the invention comprises the novel features of construction and combination of parts more fully hereinafter described.

In the accompanying drawings, Figure 1 is a plan view of a mechanism embodying the invention. Fig. 2 is a'vertical longitudinal sectional elevation thereof. Fig. 3 is a detail plan view of a portion of the carrier.

Referring to the drawings, 1 designates a tank having a horizontally-inclined bottom 2, provided at its forward lower end with a comparatively high end wall 3, the tank being provided with side walls 4:, the upper edges of which extend horizontally in a plane with the upper edge of the wall 3 rearward a suitable distance and thence incline upwardly in a line parallel with the plane of the bottom 2, while to the upper edges of the inclined portions of the side walls are attached contact members or strips 5.

Arranged for longitudinal sliding movement within the tank 1 is a carrier 6 in the form of an open frame composed of longitudinal members or bars 7 and transverse members or bars 8, there being connected with the rear end of the carrier a contact member 9, having at its ends contact portions or fingers 10, adapted in practice to override the contact-strips 5, the carrier 6 being intended to receive the plate 11 to be treated and to support the same within the solution in the tank.

The contact-strips 5 have their front terminals upturned, as at 11, to produce abutments with which the fingers 10 contact for limiting the forward movement of the carrier.

Arranged in the forward portion of the tank and parallel with the inclined bottom 2 are longitudinal cleats or supports 12, which when the carrier is in active position contact at their rear ends with the contact member 9 and which support an anode 13 immediately above the carrier and the plate 11 thereon during the process of coating the latter.

Connected with the anode 13 is a suitable wire or wires 14, and with the contacts 5 a wire or wires 15, the wires 14: and 15 being extended to connect with a dynamo, (not shown,) whereby an electrical current will be established through the anode, contacts 5 and 9, and carrier 6 when the parts are in active position.

In practice the carrier will be moved to the dotted-line position illustrated in Fig. 2 and at the upper portion of the tank for the reception of the plate to be treated and after receiving the plate be returned to the full line position shown in said figure, with the plate resting beneath the anode and the various parts of the apparatus in contact, as above described, for establishing an electric circuit whereby the metal contained in the solution in the tank will be deposited upon and coat the surface of the plate 11, as usual in this' class of devices. It will be noted, however, that under my improved construction the plate 11 will be maintained in a horizontally-inclined position substantially parallel with the anode, whereby the plate will be prevented from buckling, thereby obviating liability of its coming in contact with the anode 13 and at the same time insuring a uniform deposit of the coating upon the plate. Furthermore, it will be observed that owing to the improved form of tank employed the amount of solution necessary forthe process will be minimized and that by employing the carrier the plates to be acted upon may be readily introduced into the solution. In attaining these ends it isto be understood that minor changes in the details of construction herein set forth may be resorted to without departing from the spirit or scope of the invention.

Having thus fully described the invention, what is claimed as new is 1. In a device of the class described, ahorizontally-inclined tank, an anode supported therein, a plate-receiving carrier movable longitudinally of the tank and adapted to enter beneath the anode, and means for establishing an electric circuit through the latter and the carrier.

2. In a device of the class described, a tank, longitudinal contact members carried by the Walls thereof,a longitudinally-movable carrier having a member arranged to move in contact With the first-named contact members, and an anode supported Within the tank in spaced relation to'the bottom of the latter and adapted to receive the carrier beneath it.

3. In a device of the class described, a tank having a bottom inclined from the horizontal,
