APPARATUS FOR THE GENERATION AND DIRECT ELECTROLYTIC APPLICATION OF ELECTRIC CURRENTS.

- SPECIFICATION forming part of Letters Patent No. 726,659, dated April as, 1903. Application filed January 10,1902. Serial No. 89,187. (No model.)

To all whom it may concern.-

Be it known that I, FRANCIS EDWARD EL- MORE, a citizen of England, residing at 4 Bishopsgate street within, in the city of London, England, have invented certain new and useful Apparatus for the Generation and'Direct Electrolytic Application of-Electric Ourrents, (for-which I have applied for a patent in Great Britain, dated December 31, 1901, No. 26,673,) of which the followingis a specification. A

This invention relates to apparatusof the unipolar-dynamo-kind for generating large electric currents and applying'themdirectly to electrolysis.

The chief objects of the invention are to overcome in great measu'rethe difficulties hitherto attending the collection and distribution of large currents and to obtain electro deposits rapidly andeconomically. Apparatus'for this purpose may be made in many different forms, according to the various purposes to which they may be-applied.

The accompanying drawings serve to illustrate a convenient form of apparatus according to this invention. I t Figure 1 is a side elevation, and Fig.2 is a vertical section of half, drawn to an enlarged scale. a

a. is a vertical shaft which is drivenby bevel-gearing b c andfhas its lower end ex tending as a plunger into 'a hydr'aulic' cylin der (2. The horizontal bevel-wheel 1) runs be tween upper and lower bearingsand is fitted on the shaft a with keys sliding in grooves, so that while the-wheel revolves with the shaft the shaft can slide longitudinallythrough it. On the upper part of the shaft a is fixed an iron disk e, having at its peripherya deep flange f, which may be termed the armature. This: armature extends down into the interior'of a cylindrical electromagnet having a' base outer" and upper side g and an inner side h; also, a cover 2', which is the periphery of a frame carrying the upper bearing for the shaft'a.

j is a cylindrical shell of non-magnetic metal lined externally with insulating material, on which are wound a number of coils 7c, of insulated hoop, each coil separated from the next above terial.

To the flange f is attached a cylindrical shell Z, of good conducting metal, such as copper, the edge of which dips into a trough it by a layer of insulating inam, containing fluid-conducting material, preferably an alloyof lead and mercury, the fluidity of which is insured by a. steam-pipe 2 at the bottonrof the trough. The shell Z con tinues as a lining of'the underiside of'the disk e,-and the one side '21 of'the trough m,

-which is insulated froin h, turns overit and extends downto form the sides'o and bottom of a cylindrical tank or cell having its bottom resting on insulating.material on the base of the apparatus. Theuta'nk 0 is of 'metal, such as lead, which is not attackedby the electrolyte. From the bottom of the tank o'extend upward a number of anodes, each in the form of a cylindrical shell 10, held in :position by longv bolts 3, passing through it Q at intervals and fixing it in a groove in adisk 'q,of lead or equivalent metal, at the bottom.

To the lining] of the disk e are attached'a number of cathodes 1", each in the form of a cylindrical shell, tapering in thickness, so as .to' be thinner at the lower end than at the top. They are fixed to the disk e by screwed 'sleeves 3, through which pass setting-screws torevolve, while the tank or cell 0 is charged with suitable electrolyte liquid, a large electrical currentis generated, which passes from f through the alloy'in m to the cell 0 and its bottom, thence along the anodes 10 and through the electrolyte to the cathodes r,

thence back to f, the resultbeingthat the 5 metal of the anodes p is rapidly dissolved and deposited on the cathodes 4". When desired,

the coverz'can be unscrewed,leaving the frame and copper bearing of the shaft free. 7 The shaft can then be raised by pressure in the hy- IOO draulic cylinder 01, raising with it the disk e and the cathodes r with the metal deposited on them, which can be pushed off them by means of the screws 25. The deposited metal forms a shell inclosing each cathode r, the upper edges of the shells on two cathodes terminating at the under side of the block u between them. Now on screwing down the screw 15 the block to is pushed down, forcing the shell of metal off, this being facilitated by the taper form of the cathode. It is of course to be understood that this removal of themet-al from the cathodes is effected when they are all lifted out of the cell along with the upper part of the apparatus to which they are attached. As the part i of the magnet extends over the flange f, there is a certain amount of attraction tending to raise the disk 6 with the cathodes and shaft, thus reducing to a certain extent the gravitating effect of these parts. The ribs of the disk 6 as they revolve act as the blades of a fan, causing currents of air to pass through the air-spaces of the magnet and through between its coils to outlets w, thus keeping the coils cool.

Although I have shown and described the cathodes attached to the disk 6 and revolving with it, while the anodes are stationary, obviously this arrangement might be inverted, the cathodes being fixed to the bottom of the cell, while the anodes are attached to and revolve with the armature-disk e.

Having thus described the nature of this invention and the best means I know of carrying the same into practical effect, I claim 1. In an organized structure, an electrolytic cell and a unipolar dynamo-electric machine, the armature of the latter being in direct electrical connection with the anodes or cathodes of the former.
