HENRY ROBERTS, OF PITTSBURG, PENNSYLVANIA.

METAL-COATING APPARATUS.

Specification of Letters Patent.

Patented April 6, 1909.

Application filed January 7, 1909. Serial No. $71,069.

To all'whom it may concern:

Be it known that I, HENRY ROBERTS, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a cer- 1 tain new and useful Improvement in Metal- Coatmg Apparatus, of which the following is a full, clear, and exact description, reference being had to the accompanyingdrawings,

- forming part of this specification.

The object of my invention is to providein metal coating apparatus wherein the metal after being subjected to a cleaningtoripre paratory treatment is caused to be passed;

. through a molten bath of coating material,

. side elevation; and Fig. 4 is a fragmentary the tension adjustment screws 8'.

sectional view of a wiping roller to beherein after referred to.

I shall now describe my invention so that others skilled in the art to which it appertains may understanr' and construct the same.

In the drawings, the reference numeral 2 indicates the coating bath of a metal coating mechanism. Journaled in the bearings 3 and 4, slid ably mounted in the ways 5 of the framework 5 overhanging that end of the bath 2 from which the coated metal emerges, are the rollers 6 and 7. The roller 7 is sur faced with a wiping material against which the moving coated metal is adapted to be forced by means of the roller 6 throu h the medium of coiled springs 8, provide with By means of the pin arrangement 9 the bearings 4 of the roller 7 may be held against movement in the ways 5 of the frame 5, while also a1- lowing of the ready removal of the rollerfor the insertion of another roller when the wipguished from a brush which .will leave a I more or less uneven surface. I prefer, however, to use mineral wool, as asbestos, as I I find this to be admirable wiping material by reason of the fact that it does not adhere to the melted coating metal. In Fig. 4 I show the roller 7 formed with the peripheral recesses mend around this recessed surface I place a layer of mineral wool or asbestos 11, which is bound to the surface of the roller by means ofthe asbestos rope 1.2. The wiping material applied to the roller in this manner pre- ,sents a surface that is not easily disintegrated by the abrading action. of the metal during the wiping operation, the cushion effect caused by the interposed layer of the material producing an efiective wiping action.

The constructionof th'e wiping roller or 1 rollers may vary according to the shape or pattern of the metal to be coated; For in stance, in the case of wire fabric, where con.

nective knots or joints are present, it vfill be apparent that these knots or joints will have more of an abrading or disintegrating action on 'the wiping material during the Wiping operation thin the strands or boay por tions of the fabric, in which case it would be desirable to provide those portions of the or joints contact, with a thicker wiping surface than would be required for the body of the fabric. Also in the case of wire strands, only those portions of the rollervadapted to receive the strands may be provided with wiping material.

The wiping rollers 6 and 7 are adapted to be rotated by any suitable means in a direction opposite to that of the moving coated metal which passes upwardly from the coating bath to between the rollers 6 and7, as shown in Fig. 1. Any suitable mechanism may be employed for drawing the metal through the coating apparatus.

The advantages of my invention will be appreciated by those skilleel in the art.

adaptable to the coating of wire fabr'c, the

such as to insurethe contact of the wiping material with every portion of the coated fabric as it emerges from the bath.

While I have shown and described my apparatuses having only one" roller provided with wiping material, it will be appa re it that several rollers may be employed ll deslred. Many other changes will suggest themselves The invention will be found particularly construction of thewipingmechanismbeing to. the mechanic which .would not be a departure from my invention and I do not therefore desire to limit myself to the precise construction shown. c

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

I 1. A roll for removing the surplus coating from metal as it emerges from a coatingbath, having a covering of suitable wiping -material andfa cushioning material between the body of the roll and the Wiping surface.

- wipin surface.

2. A roll for removing the surplus coating from metal as it emerges from a coating bath, having a covering of suitable wiping material and a cushioning medium also of wi mg material between the body of the roll an the roll for removing the surplus coating from metal as it emerges from a coating bath,

hayingja complete covering of wiping mate- 7 ma 4. A roll for removing the surplus coating a from metal as it emerges from a coatingbath,

having a complete covering comprising a rope or strand of wiping material.

r5. A, roll for removing the surplus coating from metalas itemerges from a coating bath,

. having eripheral recesses, a cushioning medium o wiprngmaterial filling said recesses and covering the surface of the roll and an external covering of wiping material sur rounding and binding said cushioning medium.

6. A roll for removing the surplus coating from'metal as it emerges from a coating bath,

bearings slidably mounted in said guide Ways, detachable means for retaining said bearin s therein, and a spring" ressed tension ro er having bearings slida ly mounted in said gulildeways and cooperating with said r0 er.

Wiping 8. p aratus for removlng the surplus I coating rom metal as it emerges from a coating bath comprising a supporting frame provided with guideways, a wiping roller surfaced with wiping material and having bearings slidably mounted in said guideways, detachable means for retaining said bearings therein, and a spring-pressed tension roller having bearings slidably mounted in-said guideways and cooperating with-said wipin roller, said wiping rollerbeing provide with annular flanges adapted to extend beyond the ends of the tension roller.

In testimony whereof, I have hereunto set my hand. I
