GEORGE M. WRIGHT, OF WORCESTER, MASSACHUSETTS, ASSIGNOR OF ONE-HALF TO THE WRIGHTdz OOLTON WIRE CLOTH OOil/IPANY,OF

SAME PLACE.

APPARATUS FOR GALVANIZING WIRE.

SPECIFICATION forming part of Letters Patent No. 518,048, dated April 10, 1894.

Application filed July 10 1891- To aZZ whom it may concern:

Be it known that I, GEORGE M. WRIGHT, a citizen of the United States, and a resident of Worcester, in the county of Worcester and State of Massachusetts, have invented a new and useful Improvement in Apparatus for Galvanizing WVire, of which the following is a specification, reference being had to the accompanying drawings, forming a part of the same, and in which Figure 1, denotes a side elevation of a galvanizing apparatus embodying my invention. Fig. 2, isan end view upon a larger scale of the expansible drum, upon which the wire after being galvanized is wound. Fig. 3, represents the same part of the expansible reel as is shown in end view in Fig. 2, but in sectional view on line X, X, Fig. 4, and Fig. 4, is a central longitudinal sectional View of the expansible reel.

Similar letters refer to similar parts in the several figures.

My invention relates to a galvanizing apparatus for galvanizing Wire, wire cloth, or

wire netting and it consists in the construction and arrangement of the several parts as hereinafterdescribed and specifically set forth in the annexed claims.

Referring to Fig. 1, A denotes a'roll of wire, wire cloth, or netting mounted upon a suitable stand or support B, preparatory to its being galvanized. I

The material to be galvanized is conducted over a small roll 0, through a bath of molten zinc contained in a galvanizing pan or vat, indicated by the broken lines D.

The material to be galvanized denoted by a, is immersed in the molten metal by being conducted beneath a roll E, thence over the roll F, to a winding roll G, mounted upon the supporting stand H, the roll G, upon which the galvanized material a, is wound consisting of two heads I, I, attached to a rotating shaft J, journaled in the bearings J, J, and driven by a pulley J The heads I, I, are provided at their edges with a series of radial recesses K, in which are fitted the sliding plates K, K, each capable of a radial sliding motion within the slots K, extending across the reel and attached to the sliding plates K, upon the opposite heads are bars K upon Serial No. 399,101. (No model.)

the shafts L, and outside one of the heads I,

are pinions O, engaging a spur gear P, turning loosely upon the end of the shaft .I. The gear P, is provided with a crank handle P, by which it can be conveniently rotated about the shaft J, and it also has a concentric'slot P through which passes a binding screw P entering the head I, and having a handle P by which the gear P, is clamped upon the head I, and held from rotation. The gear P, is rotated to bring all the crank arms M, upon the outer sides of their shafts L, and in a radial position, causing the plates K, and connected reel bars K to be pushed outward in the position shown in Figs. 2, 3, and 4, to receive the galvanized material. The gear P, is then held from rotation by the tightening bolt P holding the plates K, and reel bars K securely in position with the reel at its greatest diameter. When the coil of wire netting or cloth has been wound upon the reel G, the tightening bolt. Pi, is loosened and the gear P, rotated, thereby rotating the shafts L, by means of the pinions O, and drawing the plates and connected reel bars K inward toward the center of the reel, reducing itsdiameter and allowing the coil of galvanized wire netting, or cloth to be drawn off over the end of the reel. 7 The plates K, and connected reel bars K are then expanded to their greatest diameter, as shown in Figs. 2, 3, and 4, and the operation repeated.

The use of an expansible reel, substantially as described, in connection with a delivering roll and galvanizing pan permits alarge quantity of galvanized material to be wound upon the reel and" readily removed by reducing the diameter of the reel.

I do not confine myself to the specific construction and arrangement of the operating mechanism by which the reel bars and their attached plates K, are moved radially in the nation of the delivery roll, or mechanism by which wire, wire netting, wire cloth, or similar material, is delivered to a galvanizing vat, or pan, a galvanizing vat, or pan, through which the material to be galvanized is passed, and an expansible rotating reel arranged to receive the galvanized material from the galv anizin g pan, or vat, saidexpansible reel conslsting of a rotating shaft, heads carried by said shaft, reel bars extending between said heads and arranged concentrically with said rotating shaft, and actuating mechanism by -which said reel bars are moved radially, substantially as described.

2. In a galvanizing apparatus, the combination of a galvanizing pan, or vat, a roll E within said galvanizing vat, a rollF journaled above said vat and an expansible winding reel G consisting of a rotating shaft J, heads I, I, carried by said shaft, plates capable of sliding radially in said heads, and reel bars attached to said plates and extending between said heads, substantially as'described.

3. In a galvanizing apparatus, the expansible reel upon which the galvanized material is wound, said reel consisting of the heads I, I, provided with a series of radial slots K, at their edges, sliding plates having a radial motion' within said slots, reel bars connecting said sliding plates and connected actuating mechanism by which said sliding plates and connected reel bars are moved in and out and the diameter of the reel varied, substantially as described.

4:. The combination in an expansible reel for winding galvanized wire, wire netting, or wire cloth, of the heads I, I, attached to a r0- tating shaft, shafts L, j ournaled in said heads, crank arms carried by said shafts, links conmeeting said crank arms with a series of plates having a radial sliding motion in said heads, reel bars connecting said plates upon which the galvanized material is wound, pinions attached to said shafts L, and arranged concentrically around an actuating gear and an actuating gear P, engaging said pinions, whereby the shafts L, are rotated and a radial sliding motion imparted to said plates and connected reel bars, substantially as described.

Dated at Worcester, in the county of Worcester and State of Massachusetts, this 2d day of July, 1891.

GEORGE M. WRIGHT.
