' MASSACHUSETTS.
ELECTRIC FURNACE;
. Specification of Letters Patent. 1 Patented NOV.'12, 1912- Application filed March 14, 1912. Serial No. 683,891.
North Adams, in the county of Berks ire and State ofMassaohusetts, have invented Electric Furnaces, of which the following is a specification. v
Thlsl'nvention relates to furnaces 1n which the heating medium is obtained by an electric are formed between-two Separated elec trodes, and it is the object of the invention to provide a furnace having a movable electrode,- together with novel and improved means for adjusting the same so as to 'facili tate the bringing of the material to be acted on directly within the influence of the arc.
Inorder that the invention may be betterunderstood reference is had to the accompanying drawings in which,
Figure 1 is an elevation of the furnace, partly broken away; .Fig; 2 is a plan View with the casing of the furnace removed, and
f Fig; 3 is a cross-section on the line 3-3 of 25' Fig. 2.
Referring specifically to the drawing, 10 denotes a table, stand or other suitable supportwhich forms the .base of the furnace, and supports a chamber '11 in which the electrodes are mounted. At the center of the base. is mounted'a fixed or stationary electrode which is a'disk 12 of carbon or other suitable conducting material to which is suitably connected a current conductor 13. The movable electrodes are arranged in agroup of four above the disk 12 and are adjustable vertically relative thereto, and
also laterally parallel to the plane of "the top of the disk. The movable electrodes are therefore adjustable with :respect to the fixed'electrode in planes at rig'ht angles to one another. Each movable electrode is a pencil 14' of carbon or. other'conduct-ing material, the same being carried by a holder which is adjustable so that the aforesaid adjustment of the electrode may be readily 'efiect ed- As the holders of the several electrodes are alike, a description of one sutfices for all.
On the base .10 are guides 15 in which is mounted a slide 16, the guides being arranged 'so that the slide may be .carried toward and from the fixed electrode 12.
The slide is operated by a screw '17 thread- I ed through a bracket 18 mounted on the edge of the base. Any other suitable means for operating the slide may be provided. The slide carries a rotatable .disk 19 having a hub- 20 which seats in a bearing opening in the slide. On the underside of the disk andwhen moved in the opposite direction,-
takes hold of the rack teeth and rotates, the a disk 19.
From the top of the disk 19, at the center thereof, rises a post 23 having a vertical guideway 21 in which is slidably mounted a' block From the bottom of thelblock depends a stem 26which passes through a central opening 27 in the disk 19. and the hub 20 thereof, and has connected to itslower' end alever 28 fulcrumed to'a bracket 29. on
the. bottom of the slide 16. The lever is mounted. to swing in a vertical plane and therefore serves to move the block 25 up and'down in the guideway 24. To the post 23, above the block 25, is fulcrumed intermediate itsends, as indicated at 30, a lever 31 having one of its ends connected by a link 32 to the block 25. To the other end of the able clamp 34 for holding the electrode 14,- the current wire for the latter being indicated at 35. The parts carrying the electrode 11 and its current wire'35f'will be suitably insulated from the parts supporting the fixed electrode 12.
,lever 31is connected a downwardly-extending arm 33 carrying at its lower end a suit-' The lever 31 swingsin a verticallplane, inview of which it will be evident that by.
ing the electrode support toward or from the electrode 12', and moving the electrode 14 radially with respect to the latter. The operation of the disk 19 rotates the electrodeholder and. swings the electrode 14: in a curve across the top of the electrode 12. The elecary electrode mounted on the base, a slide carried by the base and movable laterally toward and from the stationary electrode, a rotary holder carried by the slide, and an electrode carried by said holder.
'2. In an electric furnace, a base, a stationary electrode mounted on the base, a slide carried by the base and movable laterally toward and-from the stationary electrode, a rotary and vertically adjustable holder carried by the slide, and an electrode car ried by said holder.
3. In an electric furnace, a base, a stationary electrode mounted on the base, a slide carriedby the base and movable laterally toward and from the stationary electrode;
a rotatable disk carried by the slide, a holder carried by the disk, and an electrode carried by the holder.
4:. In an electric furnace, a base, a stationary electrode mounted on the base, a slide carried by .the base and movable laterally toward and from the stationary electrode, a rotatable disk carried by the slide, a vertically adjustable holder carried by the disk, and an electrode carried by the holder.
5. In an electric furnace, a base, a stationary electrode mounted on the base, a slide carried by the base and movable laterally toward and from the stationary electrode, a rotatable disk carried by the slide, a post carried by the disk and having a guideway,
a block slidable in the guideway, a lever fulcrumed on the post, an electrode holder connected to one end of the lever, a connection between the other end of the lever and the block, and means for adjusting the block in the guideway.
6. In an electric furnace, a base, a stationary electrode mounted on the'base, a slide carried by the base and movable laterally,
toward and from the stationary electrode, a rotatable disk carried by the slide, a post carried by the. disk and having a guideway, a block slidable in the guideway, a lever fulcrumed on the post, an electrode holder connected to one end of the lever, a connection between the other end of the lever and the block, a stemextending from the block, and a lever fulorumed on the slide and connected to the same.
7. In an electric furnace, a stationary electrode, and a movable electrode adjustable with respect to the stationary electrode in planes at right angles to one another.
In testimony whereof I atfix my signature in presence of two witnesses.
