ELECTROPLATING WIItZll-CILOTH.

Specification of Letters Patent. Sept. 19, 1911 Application filed June 2, 1911. Serial No. 630,841.

To all whom it ma'y'concem: i 1

ll3e it known that I, FRANCIS J. Roo'r, a cltizen of the United. States, and a resident of the borough of -Manhattan of the city of- New York, in the county and State of New York, have invented certain new and useful Improvements in the Electroplating of Wire-Cloth, of which the following is a specification.

The invention relates to new and useful improvements in the electroplating of long.

Figure 1 isa perspective view of the ap paratus showing the work in position therein anda portion of the side of the tank re,- moved." Fig; 2 is aside elevation showing the work in position and a portion of the side of the tank removed. Fig. is a transverse sectional view and Fig. 4 1s a partlal plan view.

The tank 1 is made of wood and is watertight to hold any suitable bath or solution which may be desired during the plating process. Within the lower portion of the tank and also above the tank are rollers 3 and 4: which extend transversely thereof. The-material, moved along by suit-a e pull ing or propelling means, enters the'appa- 'ratus, passes over a roller in the upper set then down into the bath under a rollerof the lower set, out of the bathover another roller of the upper set and so on in vertical 'folds or loops through the apparatus. It

will be observed that the rollers are in staggered arrangement so that those in the lower "set are located below the spaces between ad- .jacent rollers of the upper set. Directly below the rollers of the upper set and above the rollers of the lower set are the metal anodes 5 for providing the plating material.

The lower rollers 3 .are supported within thetank by means of bearings 6 carried on the longitudinal members 7, and the upper rollers 4 are supported .in metal bearings 8 carried on the longitudinally extending members '9 and 10 which'are held in place by the uprights 10.

Either one or both of the members 9, see-Fig. 1, may be made of a metal which will readily conduct electricity and therefore can serve as a bus bar or common electrical connecting means for the upper rollers or cathodes all of which are electricallyv connected thereto. This bus bar or common electrical connecting means is connected to the negative terminal of an electric'circuit the positive end ofwhich is connected to the anodes.

Theanodes 5 are supported .in place by and T suspended from rods 11 extending transversely across the upper portion of the tank. Each of these rods is provided with a depending member-l2-lea'ding to another bus bar or common electrical connecting means 13 to which the positive terminal of the electrical circuit is connected. The anodes are provided with hooks to hold them in place and it is obvious that one which has been used can readily be .replacedby a new one, when desired. The anodes are arranged directly over t e lower rollsand beneath the upper rolls nd are located within the extremities of the ody portion thereof. It is apparent that said anodes are between adjacent vertically extending portions of the folds or layers of t ewo'rk as it passes through the apparatus thereby bringing all portions of the two broad surfaces of the work close thereto, thus enabling a uniform. deposit of obtained.

' In coating pieces of work like wire cloth such as is used for ordinary window screening to keep out insects, this apparatus is particularly useful.

It will-be observed that the work passes out of the bath each time it passes over an upper roller and this aids in breaking any bubbles of gas which may have been formed upon the work and also permits gas accumu-. .lation to pass ofi'or dissipate into the atmosphere As the rollers in the upper set are all connected to an end of the electric circuit the work passing thereover will also be recharged prior to being reintroduced into the bath.

With the upper rollers or guiding means located above the bathit will be observedthat the work can be readily inspected at all. stages in its assage through the apparatus thereby permitting the apparatus to be operthe coating substance upon the work to be ated and the process-to be effected in the 15 ,wire cloth the process which consists in passwhile in the bath within which the lower All of the rollers as shown are provided with flanges to retain the work in place 5 ,--"t hereupon. The work could, however, be

retained place by other means if desired. The rollers, serve for guiding the work through the apparatus and lso for providing means to conduct the e ectricity to thework at several points along its path through the apparatus; When driven they also serve as means for propelling the work.

1 It is obvious that various changes may be made without departing from the spirit and scope of the invention.

I claim as my invention: 1. In the manufacturing of electroplated ingjin a continuous path a long strip of Woven wire cloth alternately over and under upperand lower rollers and electrically depositing the plating material upon the cloth and while the work is intransit in the bath of the work.

' electrically depositing plating material thereupon from anodes located between the folds 3. In the manufacture of wire cloth the passing of a long. stripof cloth through an 'elect-roplating'bath in the presence of anodes composed of the plating metal located between adjacent layers of the cloth and simultaneously with the passing of the cloth thrbugh the bath sending an electric current to the anodes and leading said current from the cloth at a plurality of places along the path of its travel.

4, The method which consists in bringing r a portion of a long strip of wire cloth into an electroplating bath in the presence of anodes composed of the plating metal in said bath and while said portion of the strip is in the bath in the presence of said anodes sendto ing through the same an electric current over an electric circuit the positive pole of which is connected to the anodes and the negative pole of which is connected to the cloth at' di'iferent points along the latter.

5. The method which consists in the passing of a long strip of wire cloth in a continuous path through a bath having therein anodes arranged so that they are opposite to the fiat surfaces of the cloth and supplying an electric current which passes in at the anodes and out of the cloth at several different points along its travel.

6. In the manufacture of wire cloth the passing of a long strip of said cloth alternately over and under upper and lower rollers, at least the lower'ones of which are immersed in an electroplating bath, past anodes which are located between the folds of the cloth and supplying an electric current which passes in through the anodes and which is conducted from those portions of the cloth which passes over the upper rollers.

.This specification signed and witnessed this 18th day of May,'A. D., 1911.
