Our invention contemplates the formation or production of the voltaic are between the metal to be operated on and a conductor which is brought for said purpose into proper proximity to that point on the metal which is to be operated on, the conductor forming one pole,while the metal to be worked constitutes in itself the other pole. In other words, the metal to be workedand the conductor extraneous to said metal constitute two electrodes or terminals, by the approach of which to each other the circuit in which both are included can be completed through the voltaic are pro duced between them. It is this feature which mainly characterizes our invention, and which differentiates it from other methods which have been proposed of working or melting metals by the electric current.
The advantages attending our invention are, briefly stated, its simplicity and efficiency, as well as its wide range of application in the industrial arts.
The only apparatus needed to put this invention into practice outside of the electrical generator or source of electrical supply, and the circuit leading therefrom to the metal to be worked and to the extraneous conductor, is a holder for the said conductor, the holder and the metal to be operated on being so arranged as to be movable relatively to each other, so as to bring the conductor opposite to any desired point on the metal. lVe prefer, usually, to move the conductor holder over the metal. 'The conductor preferably consists of astick or cylindrical rod of carbon. The form and material of said conductor, however, are not essential features.
In the accompanying drawings we have shown some forms of apparatus,which wewill now proceed to describe, in order to more fully explain the manner in which our process can be practically applied.
Figure 1 is a side elevation, partly in sec- 5 tion, of a simple form of carbon-holder. Fig.
2 is a like view of a holder adapted to rest upon and be moved over the face of the metal plate or plates which are to be operated on. Fig. 3 is a side elevation of a modified form of 6 5 apparatus. Fig. 4is a section on line 4 4, Fig.
3. Fig. 5 is a section on line 5 5, Fig. 3. Fig.
6 is a plan of the rails on which the holder shown in Fig. 3 is mounted. Fig. 7 is a side elevation of a form of apparatus in which the carbon is stationary and the metal to be operated on is movable under the carbon. Figs.
8 to 21 represent various applications of the invention or uses to which it may be put.
The holder shown in Fig. 1 consists of a 7 wooden or other non-conducting handle, A, having in its rear end a socket and bindingscrew, B, electrically connected to the conducting stem or shank G, to which is jointed or hinged at H a sleeve, E, containing the carbon pencil D,heldin place therein by clampscrew F. The binding-screw Bserves to hold in place the metallic conductor O,which leads from one pole (usually and preferablythe pole) of the source of electricity. The other pole of said source of electricity is connected to the metal to be operated on. When the carbon D, under these conditions, is brought into proximity to the metal to be operated on, the voltaic arc will be produced between the 0 two, with the effect of heating, softening, and finally melting the metal at the point where thearc meets it. The holder can be moved over the metal from one point to another to act on it in a continuous line, or at separate points, as desired. I
The apparatus shown in operation in Fig.
' 2 consists, also, of a wooden handle, A,with a metallic socket and binding-screw, B, at its rear end, metallic shank G, jointed sleeve E,
clamp-screw F, and carbon pencil D, as in the:
preceding figure. Handle A has a fiat base,
A, which rests upon and can move over the two metal plates 0" r to be operated on. The
conductor 0 for the carbon, leads from the pole of battery X, (typical of any source ofv gether at 00, and its front end, G, is continued.
back of the joint in the form of a lever, G, which extends underthehandle A. A spring, K, keeps the part G, and consequently the carbon D, lifted, thus maintaining a normallyopen circuit. By pressing lever G toward the handle the carbon "can be lowered into proper proximity to the 'plates 1", r to producebetween it and them the voltaic are. In this figure the apparatus is shown in operation uniting the two plates by a process akin to riveting. By the action of the voltaic are the metal is gradually melted, the fusion extending through into both plates, the melted portions of which are mingled together, so that when the same cool the two plates, as to said fused portions, are virtually in one homogeneous piece. v
The apparatus shown in Figs. 3, 4,5 in the main resembles that illustrated in'Fig. 2. Itsbase is provided with front and rear pairs of flanged wheels, which run upon either one. of
two pairs of rails, L L, on a track-frame, M. The rails L are cogged or toothed, as shown, and aredesigned to be used when the holder is employed for'what may be termed pointunion-that is to say, for operating on the metal at points whose distances from one another will be equal to the distance intervening between the teeth of the rails. The other rails, L, are ordinary straight smooth rails, and are to be used when the holder is"em-' ployed for uninterrupted or continuous union. This holder is provided with a screen, N, of colored glass, attached to the holder by a uni- 'versal joint at O,which will permit it to be set in any positionrequired, in order to shield the eyes of the operator from the injurious effects of the voltaic are. It is also provided with a secondometer or other suitable timepiece, P, having a stop-lever, a, connected to and arranged to be operated by an arm, I), attached to the handle end of vibratory stem G. Normally the handle end G is depressed by its spring, thus lifting the carbon and breaking the circuit, and the parts are so adjusted thatin this position the arm b will bring the stoplever to position to stop the time-piece. WVhen, however, the handle is pressed'upward,
thus .bringingthe carbon into action, the stoplever will be moved in a direction to permit the time-piece to start. In thiswaythe duration of the operation, in the case of point-union particularly, can be accurately determined.
It will be of course understood that, instead of connecting the wire from vone'pole of the battery directly to the metal to be operated on, 'it can be connected to a metallic plate or stand, which serves as a working-bench to support the metal operated on, the two being of course in electrical contact. Sucharrangement is represented in Fig. 7, the apparatus being designed for use as a forge. The stand Bis furnished with a grooved guide-pulley, c, which receives and supports the metal tangs or shanks of pinchers S, whose handles are sheathed with wood or other'insulating material. The pinchers are in electrical contact with the metal pulley, over-which they can move to bring the article heldloy them (in this instance supposed to be a chain-link) rm der the'carbomwhich is supported in astationaryholder. The circuit-connections are the same in the other figures. The metal to be operated on can in this apparatus be heated to the desired extentfand then can be transferredto the usual anvil and forged in'the cus-. tomary way. 7
Our invention, as hereinbefore indicated, is susceptible of awide range of application. It can be'used, for instance, for joining metals whether end to end or placed one on top of the other, for'making holes in metal,'or for dividing a piece of metal into two or more parts,
for steelifying, and for numerous other purposes. I e v Figs. 8 to 19 represent some of the ways in which metals may be joined by our invention.
These figures require no explanation, further than to say that the darkened points or lines in them indicate where the metal-has been operated on.
Fig. 20 illustrates the manner in which holes may be bored in metals.
Fig. 21 represents a metallic plate having pattern of fused metal incrusted thereon. The
plate is heated to the temperatureof fusion 'atthe point where the extraneous metal is to be applied, and said metal in fused condition is dropped upon the heated point or points, thus 'forming'a metal incrus'tation, which enters and becomes part of the plate. .Inthis way we can incorporate into the plateother metals, granite, porcelain, &c.
From the foregoing it will be observed that the essence of our invention is thatthe'metal itself at the point wh'ereit' is operatedon becomes one pole of the voltaic arcfwhile the carbon or other extraneous conductor "approaehed thereto constitutes the other'pole.
Having now described our inventionand the bestway at'present known'to'us of carrying thesame into effect, what we claim, and desire to secure by'Letters Patehtjis as follows 1. The improvement in the'art of joining or IIO separating metals by means of the directlyapplied electric current,which consists in forming the voltaic are at the desired point or points, or along the desired line or lines, on said metal by a conductorapproached thereto, which constitutes one pole, while the metal itself constitutes the other pole, as and for the purposes hereinbefor'e set forth 2. The process of topically working plates, blocks, or other solid masses of metal, which consists in forming the voltaic are at those points only of the metal which are to be Worked, (leaving the other portions of the same unaifected,) through the agency of an extraneous conductor, which constitutes one pole, while the metal itself constitutes the other pole, as and for the purposes hereinbefore set forth. I
3. Thecarbon-carriage consisting of aframe adapted to rest on and move over the face of the metal to be worked, a carbon or other conductor, a holder therefor carried by said frame and movable to and from the metal on which.
