Specification of Letters Patent.

Patented Oct. 8, 1.918.

AppIication tiled February 5` 1916. Serial No. 78,329.

`forced Metal, of which the following is a specification.

The object of the invention is to produce an article having a lead coating which is secured to a ferrous gauze netting or perforated sheet, which gauze netting or perforated sheet serves as a reinforcing member for the resulting article.

The article which is the subject matter of the present invention isvin fact reinforcing lead in sheet form and vis particularly adaptable for use as a. lining'for tanks, vats or the like, but it has a broad general use and can be employed in many ways and in many-arts. For example, the product is adaptable for the making of gaskets. i

As illustrating articles which may be made according to the invention herein described reference is made to the drawing forming part of this specification and in which drawmg,

Figure 1 is a perspective view of an article partially broken away. This figure shows a portion of a lead sheet which is reinforced by a ferrous gauze.

Fig. 2 is a cross sectional view taken as I onlthe broken line 2 2 of Figc 1; and

Fig. 3 is a perspective view of an article partially broken away. This figure shows a portion of a lead sheet which is reinforced by a perforated ferrous plate.

In said drawing A (see Figs. l and 2) indicates a reinforclng member in the form of a ferrous wire gauze or netting-either iron 'or steel-made as by weaving sets of wires B and C. In Fig. aha reinforcing member A is shown and this member A is a perfo rated iron or steel plate which is made as by punching a number of holes in a sheet so as to form a netting or screen, so toA speak.

V The wire gauze, netting or perforated plate A or A is pro rly cleaned as by plc'kling in a suitable -aci in any well known manner. When cleaned it is preferably dipped in zinc chlorid or an antimony chlorid solution. The

` function of this solution is to serve as a iux y:sus

to maintain the gauze, nettin or'perforated plate in a clean condition. u he gauze, netting or perforated plate is then dipped in a molten antimony lead alloy (which will hereinafter be referred to as the alloy of binding material.) This binding alloy contains approximately from 10 to 13% antimony and is referably covered with a suitable fiux. hen the gauze is thus dipped it. acquires a coating of the binding material. The gauze, netting or perforated plate thus treated is now ready for the reception of the main covering or coating material lwhich is to provide the exterior of the final article. This main covering is a commercially pure llead or an alloy containing lead and of such a character that it acts like lead. This additional lead or lead alloy which constitutes the coating or covering may be applied to the auze, netting or perforated plate which has en dipped into the binding alloy as by pressing the treated gauze or the likeinto a thin layer of molten lead alloy some of which 'molten lead or lead alloy is allowed to solidify and remain on the treated gauze. This dipping into the molten lead or lead alloy may be continued until the required structure has been built up; or the additional f lead may be secured to the gauze or the like by placing the gauze between sheets of lead or sheets of lead alloy and passing between heated rollers. Or, the additional lead or additional lead alloy may be applied to the gauze or the line by feeding the auze between two troughs containing mo ten lead or lead alloys and which troughs are constructed so as to feed out sheets of molten metal against the gauze whereby the molten .netal thus fed will solidifyY and will adhere '5o the gauze.

When the cleaned ferrous wire-gauze,net ting or vperforated metal is first dipped into a molten lead alloy lthe latter will adhere .irmlly to or become united with the ferrous meta in the gauze. This binding' material will remain on the gauze as a thin coating as the gauze leaves the molten bath. To this thin binding coating of lead antimony a covering of chemically pure lead or a covthe form of a sheet or strip having a lead or an alloy of lead and antimony coating extending along one or both surfaces thereof. This sheet or strip is also reinforced by the ferrous gauze or perforatedsheet so that the sheet or strip is comparatively stiff and rigid even though the major portion of the material in the sheet or strip is lead which is a substance comparatively eas to ybend and will yield with comparative y a small amount of pressure. y

It will thus be observed that as a resulting' product a strip or sheet can be produced in which lead constitutes the major portion thereof but which strip is comparatively strong and self-sustaining, thus making it much more practical in many places, for instance in sulfuric acid tanks, than are the present Well known sheets of lead which are not reinforced and which frequently bulge and sag. n o

It will also be observed that the layers of lead on opposite sides of the gauze or netting reinforcing member are connected to the lead which-passes through the openings in the reinforcing member.

What We claim is:

1. An article of the class described comprising in combination a ywire gauze or perforated sheet of ferrous metal to which there is secured a continuous sheet of lead by means of abinder comprising an alloy of antimony and lead.

2. An article of manufacture havingon an exposed surface thereof lead Vwhich is reinforced by means of a ferrous wire gauze or perforated sheet, there being a lead antimony binder between the chemically pure lead and thewire gauze or perforated sheet. 3. An article of manufacture made by dipping a vferrous wire gauze or perforated sheet when in acleaned condition into a-solu tion such as zinc chlorid or antimony chlorid, thereafter dipping said gauze or sheet in a molten alloy of antimony and lead and subsequently attaching lor securing to the gauze or sheet thus treated a lead o lead alloy coating.

4; ln themanufacture of an article of the class described-the method which comprises dippin a ferrous wire gauze, netting or perforate sheet into a molten alloy lead solution and subsequently securing in placewhen4 in a heated condition a lead or leadl alloy coating, the coating resulting from said dipping operation serving as a binder berated sheet and the lead or lead alloy covtween the ferrous wire netting or perfoering.

menace 5,. ln the manuacture of an article having a lead exterior and a ferrous reinforced portion the method which comprises dipping a cleaned ferrous gauze or perforated sheet in a zinc chlorid or antimony chlorid solution subsequently dipping in a' molten antimony lead alloy binder containing antimony of approximately from 10 to 13% and .finally applying a coating of lead while in a heated condition whereby the lead antimony alloy willv serve as a binder between the ferrous metal and the lead coating.

6. In the manufacture of articles of the class described the method which comprises dipping a ferrous wire gauze, netting or perforated sheet into a bath containingan alloy of leadand antimonv in molten condition so as to provide a deposit which can be employed as a binder, and when in a heated condition applying a lead or lead antimony coating to the member thus dipped, which binder serves to secure to the ferrous gauze or sheet the lead or lead antimony coating.

7 An article of the class described comprising in combination a ferrous gauze, netting or perforated sheet that serves as a reinforcing member, a coating of lead or lead alloy and a binder between said coating and said ferrous metal, which binderl comprises lead and antimony.

8. An article of the class described comprising in combination a lead or lead alloy covering, a ferrous gauze, netting or perforated lsheet which serves as a reinforcingmember and a lead antimony binder that is attached to the ferrous gauze or sheet when in molten conditionand to which binder the covering is secured when the covering and thereof and which sheet-is reinforced bythe ferrous wires secured to the lead.
