Patented July 1c, 1906.
Application filed Novemlu'ar a, 1995. Burial no 288.022.
Be it known that I, Cumulus F. JACOBS, a citizen of the United States, residing at Chicage, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Processes for Uniting Metal Pieces, of which the following is a specifics! tion. 7
This invention relates to improvements ifnf a, process for joining or uniting metal pieces; and while it is more especially intended is: use in joining the rails of electric miles. so? as to render them-practically continuous ant?" adaptable for transmission of electric cur rents, yet it is applicable for uniting rails or metallic pieces employed for other purposes; and it'consis'ts in certain novel features'end cstepsprecticed in carrying out the process.
The-principal object of the invention is to provide a simple, inexpensive, and efficient method for ioining metallic pieces by the use of whichvwhen used for joining railway-rails a, continuous mil with perfect 'and permanent electric conductivity will be afforded at a great saving-intime, labor, and ex ense.
Iii-carrying out the recess it will understood that any suite is apparatus may be em loyed for holding the pieces of metal "wit their ends approximated, so as to reccive the unitinimaterial therebetween, and for connecting t e electric conductors to the PIBGGS of metal, and in the accompanying drawings I have shown one form of such de vices; but I do not desire to beflimited theremey be veried; but to facilitate the explanation of the procesgsothat it me. be more easily and thoron lily understood, it is deemed necessary to illustrate one form thereof V j 1 V V In order to enable othersskilled in the art to-which my invention pertains to make and now proceed to describe accompanying drawings, in which": Y Fi re 1 is 9. Inn View of two pieces oi meta, showing t eir ends a proximated and embraced by-an aperturedx ann or mold and illustrating an electric conductor clamped to" I ieces 'and'Fig. 2 is a side view thereof, part y in'section andpartly in eleva- Like numerqls of reference refer to fipondmg parfizrflhroughout both views of the The reierence-numerals S and 6 designate two p eces of metal, which may be railwayrails esnietellic pieces used for other purposes "end which have their ends approximated, so as to leave a space 7 thcrebetween; Pieced around the adjacent portions of the nieces fi and 6 is a form or mold 8, wbi'chmay be of any suitable materiel end presided itsiu'pper end with an opening 9, which -shaped or=tapered, as shown; to'communicetc tween the metallic the 'rnciten material used in the tlil ebf Eusy else be provided with an o ning 10 for "Elie discharge or withdrawal el electrolyte, and said opening may be closed by means of a plug 11 of an suitable nonr'usible materiel. Detacbab y secured" to each of the pieces of metal screw-clamp 12, or otherwise. is an electric conductor 13, each of which lesd frem a source of electric supply and have their ends electrically connected to an electrode 14, carried by each of will be readily drawings. tors 13 as with the clamps 12, yet. it is apparent that they may be connected thereto by other suitable means. When the adjacent gieces 5 end 6 have raced bythe form or mold 8, a. quantity of good eleetrol tic flux in a. molten form is poured into 1; e space 7 through the opening 9 in the form and the electric current turned on through the conductors 13, when by resscn of the conductivity of the electrolyte or flux the ends ofthe rails or pieces 5 and 6 will become heated to a. suitable degree, when by re oving the plug 11 from the open ins '10 the ux will be discharged through said openin and the s ace 7 filled with molten meta after the pi understood by reference to the being held in electric connection pleoedin said opening. Instead of using the plugged opening 1!) for the discharge 0 the flux the molten metal may be poured through the opening 9 of the form 8 into the space 7, which by reason of its greater s ecific gravity will force the flux upwar ly and out throu h the opening 9, as indicated b the. dotte arrows shown in 2 of the rawings, and this mode of removing'the flux will usually be practiced. I
By practice! tests and. experiments I have found that a flux consisting of about twentyfive per cent. (25%) of each of the followingwith the space 7 bepieces, ,so as to convey rrcess' The lower portion of the orm'B' the flux or the screw-clamps 12, as
VVVhile I have shown the conduc portions of the rails or. been surrounded or emby means of a pieces S and 6 by means of the ug 11 has been recially well adapted foruse above named, or in some instances I may omit one or more of the ingredients or may vary the proportions thereof.or I may employ a flux r an electrolyte com other in redients without departing rom the spirit 0 my invention. In practicin the process the electric current is turned 0 immediately before the molten metal is placed between the ends of the metallic pieces.
Having thus fully described my invention, What I claim as new, and desire to secure by Letters Patent, is i 1. The herein-described process of uniting metal pieces, which consists in se uring a form around the adjacent portions of the metallic pieces, placing an electrolytic flux in molten form in the space between the ends of said pieces, heating the ends of the metallic pieces through the agency of the flux and by means of an electric current, and displacing the flux by means of molten metal, subs-tam tially as described.
2. The herein-described process of uniting metal pieces, which consists in securing the ends of the pieces by placing an apertured form around the same, placing molten flux in the space between the endsof said pieces, heating the ends of the metallic pieces through the agency of the flux and by means-of an electric current, removing the flux through one of, the apertures of the form and filling the space between the ends of the metal pieces with molten metal, substantially as 'dcscribed.
3. The herein-described process of uniting,
metal pieces, which consists in securing the approximated ends of the pieces by means of an apertured form, placing-molten flux consisting of borax, finer-spar, zincehlorid, and sodium chlorid, in about the: uantitips specified, in the space between t e ends of said pieces, heating the ends of the metal pieces through the agency of the flux and by means ,of an electric current, and displacing. the flux by means of molten metal. substantially as described.
4. The herein-described process of uniting metal pieces, which consists in securing the a proximated ends of the. ieces by means oi an a ertured form whic surrounds the same, pacing molten flux consisting of borax, fluor-s ar, zincv chlorid, and sodium chlorid, in about the quantities specified, in the space betwecnsthe' ends of said pieces, heating the ends of the metal pieces through the agency of the-flux and by means of an electric current, removing the flux through the space between the ends of the metal pieces with molten metal, substantially ,as described.
5. The herein-described process of uniting metal pieces, which consists in wining a term onthe adjacent portions of the metallic pieces, placing molten flux in the spaoe beends of the metallic pieces through the agency of the flux and b means'of an electric current, turning 0 said current and then displacing the flux by means of molten metal, substantially as described.
