I EDSON G. CASE. OF NIAGARA FALLS; NEW YORK. A-BRASIVE BODY AND METHOD OF MAKING THE' SAME.

Original No. 779,639, dated January 10, 1905.

To all whom it may cpncern:

Be it known that I, EDSON G. (Dish, of Niagara Falls, in the county of Niagara,-in the State of New .York, have invented a new and useful Abrasive Body and Method of Making the Same, of which thefollowing is a specification.

This invention relates to an improved method of fastening an abrasive material to the surface or surfaces of suitable bodies to form articles which are adapted to be used for grinding or polishing other surfaces or bodies, and to the article thereby produced.

The object of the invention is to rovide an abrasive surface which is practical y inherent in the body to which it is applied, whereby the wearing qualities and permanencyof the or polishing surface is materially increased.

To this end the invention consists, essentially, in applying an abrasive substance such as carborundum, emery, or equivalent material-to the surface or surfaces of a suitable body and subjecting said body to an' electroplating process, whereby a metal coating or plating is deposited over and around the surfaces of the abrasive material and suitable body and permanently fixes the abrasive material. to said body, it being understood that under this treatment the abrasive parti cles become embedded in and fastened by the plating, producing thereby an article having the characteristics above described.

, In the drawings, Figure 1 is a sectional view of an electroplating apparatus, showing one manner of applyin the abrasive material to the part being p ated; and Fig. 2 is a metal disk 1, having an abrasive substance 2 applied and fixed thereto according to im roved method. 7 I

' ca out the objects stated, I employ any we -known form of electro lating apparatus, as A, containin a suitab e electrolyte B, in which the meta anode, as C, and the object, as 1 which is to receive the abrasive substance and plating, are immersed and electrically connected to a source of electrical energy, as D, in the manner usual for electro-' plating.

During the plating metal is deposited upon the'surface or surfaces of theobject, the abrasive substance, such as powdered or granulated carb'orundum or emery or similar material, is sifted or otherwise deposited into the electrothe electrolytic action, by which Specification of Reissued. Letters Patent. Beissued Nov. 27, 1906.

Application for reissue filed June 26, 1906- Serial No. 323,535. I

lyte and falls upon the surface ofthe object, which is supported in'such position that the abrasive substance is uniformly distributed over the surface to be prepared. It is evident, however, that this a rasive substance may be applied before immersion or before the electro ytic action begins, the only requirement being that this abrasive material be in position on the object while the platlng metal is being deposited on the body or'ob so that the abrasive particles become- 'ect iemb edded and fastened thereon and thereby.

,Having thus described my invention, what I claim, and desire to secure by Letters Patent, is- 4 1. The herein-d escribed method of making grinding and polishing surfaces upon suitable bodies, saidmethod consisting in distribut ing apowdered or granulated abrasive material over the surface of the body and at the same time electroplating the body and abrasive material while the latter is being distributed on the body whereby the plating metal is deposited-over and around the surface of the body and abrasive powder to permanently fix the latter to the body.

2. The-herein-described method of fastening abrasive material to suitable bodies, which consists in distributing a powdered or granulated abrasive material over the surface of the body, and electrodepositing metal over and around the surface ofthe body and abrasive material to permanently fix the latter to the body;

'3. The herein-described new article .of manufacture, compris'in a suitable body, a powdered or granulated abrasive material upon the surface thereof, and an electrode posited plating over and around the surface of the body and abrasive material and permanently fixing the latter to the body.

4. The herein-describedv new article of manufacture, comp powdered or granulate abrasive material upon the surface thereof,and an electrodeposited platin over and around the surfaceof the disk an ab asivematerial and perma-- nently the atter to the disk.

liu testimony whereof I affix my signature in the presence of two witnesses.
