He sets out saying that, in the manufacture jewelry or other articles in which plated stock employed, the quality the goods produced, especially when plated wire used, depends in a great degree online essay writer the care exercised the workmen in concealing as far as possible the longitudinal seam, which had generally been considered unavoidable in the making plated wire. He then proceeds The object present invention Is produce a soldered compound ingot adapted drawn down Into seamless wire, the latter being free from blisters and other Imperfections as develdped In wire produced from ingots as heretofore usually made.
To this end I preferably take a core base metal suitable dimensions and wrap a thin layer or unbroken sheet solder around I next place the same within and snugly flttlng a seamless tube or shell thesis review fine metal, addlng at one end the ingot, If deslred, a chamber in which place loose solder.

The whole then submitted the action beat fuse the solder, thereby producing a compound Ingot In which the core and seamless shell are united an unbroken film solder, as will hereiuafter In the description his drawings and his ways assembling the three parts, namely, the seamless shell, the sleeve solder, and The Interlor surface the gold shell covered with borax, and the core then placed centrally essay help websites therein, thereby forming an annular space between the adjacent surfaces. A shell or tube solder then forcibly Inserted Into the annular space the lower end the core, and the whole then subjected the action beat exceeding the fusing point the Practically I obtain the best resuit vertically suspendlng the ingot and revolving or twisting It around while in the furnace, thereby uniformly heating Its surface.
After the ingot removed from the furnace found that the contiguous surfaces the shell and core are united throughout thelr length a uniform thickness or film solder. Solder loosely placed in the chamber serves Insure the filling the annular space therewith as the fusing In lieu forcing the tube solder Into position, as before descrlbed, It may flrst inserted wlthin the gold etell, and the core then placed in position thereln, and forced some under a ligbt pressure, wlthout departing from It will thus seen that his specification describes three ways of assembling the three parts First, wrapping the sheet solder around the core, whereby bent into a sleeve surrounding the core, and then inserting the core and the sleeve solder together into the seamless shell second, placing the core centrally within the seamless shell, and then forcibly drivjng the sleeve solder into the annular space between the shell and core third, inserting the sleeve solder inside the seamless shell, and then inserting the core within the sleeve solder and driving in, The Improved method herein described making eompound Ingots, the same consisting, flrst, in preparing the surfaces the base metal core and the seamless gold shell i need help writing a scholarship essay unite with solder next, introducing the core within said shell, thereby forming an annular space between them then inserting a sleeve solder into said annular space and, finally, subjecting the whole a high temperature, which fuses the solder and unites the core and shell with a uniform thickness the same. The improved method making eompound ingots, which consists in inserting a cylindrical base metal core having a slightly reduced diameter within the outer or gold shell, the surfaces thereof having been previously mba essay editing service prepared united solder, and having a chamber formed at the upper end then inserting a thin sleeve silver or other suitable solder between the core and shell and placing loose online proofreaders solder in said writing essays services chamber and, finally, placing the whole within a suitably prepared and heated furnace, thereby fusing the solder and unlting the core and outer shell with a uniform thickness the same, the ingot, after withdrawal from the furnace, being adapted to rolled and drawn down produce seamless fiUed plated wire. On examination the proceedings in the Patent Office relating the granting this patent, will found that, in addition to the two claims now in the patent prescribing a method making the ingots, there was a third claim for the product produced from the ingot, namely, for the wire resulting from the new method, describing this wire as a new article manufacture. The Patent Office required a division the application between the method and the article claimed, taking the ground that the article did not appear to dififer from that shown in prior patents.

The applicant accordingly eliminated the third claim his patent, leaving the two claims now in the patent, striking out the parts the specification describing the product, and inserting the first paragraph which have quoted with reference the object the invention, a way assembling the parts, and a description the chamber, and the fusing process. Thus, following historically the progress the patent through the Patent Office, see the reason why the patentee describes in his claims the method assembling the parts which has mentioned second in his specification, namely, that, when drew the claim, this method assembling the parts, introducing the core within the shell, thereby forming an annular space between them, and then inserting a sleeve solder into the annular space, was the first method which had mentioned in his specification the method which now appears first found its way into the patent in its progress through the Patent Office, as have above described.
The defenses set are that the patent invahd, and that is not infringed. The defendant cites as anticipatory an custom writing services united states old English patent Richard Radisson. The material part this We cast silver or gold Into an Ingot, which plerce through the center Its length with a hole, into which run rose or reflned eopper or other suitable metal. Afterwards, when the solidification professional college application essay writers complete, thls compound ingot rolled or drawn down until It reduced the dimensions required for the wire produced, the wire being subjected the annealing and other operations wire drawing. The eopper in the interior the ingot drawn down, together wlth the exterior metal, the two metals forming but one and the same body.
The interior metal may introduced into the ingot in any other suitable manner, for example, electrotype processes, or introducing mechanically, or the aid solder, a metallie core into the lugot, or casing silver or gold around an interior core. We not limit ourselves the use eopper for forming the core the ingot, as other metals may employed for this purpose.
It best write my paper website will seen that the only reference solder in the phrase or the aid solder, referring the method putting the base metal core into the ingot. This cannot held anticipatory the method patent which provides for the cylindrical tube, the base metal core, and the sleeve solder, and the adjusting or assembhng them together. This reference the use solder is too generai and indefinite infringe the patent in suit if had corne after, and, coming before, cannot held have anticipated The patent at bar a process patent. This old English patent cannot held disclose or even dissertation review suggest its process. In speaking vague prophesies in certain English patents, Judge Shipman, in The prophetieal suggestions In any patent what can done when no one has ever decided actual and hard experience and under the stress of competition the truth these suggestions, or the practical dithculties in the way their accomplishment, or even whether the suggestions are feasible, not carry conviction the truth these frequent and vague statements. The defendant further says, in citing the prior art, that Palmer Capron were the first in the European Union make seamless goldplated ingots that they used the product in finger rings, and made merchantable goods, as early as.
