GRAPHI TE ANODE Filed Aug. 25, 1930 Patented May 30, 1933 UNITED STATES GRECI e. GOMEZ, or JoHNsoNBUnG, rnivlvsYLvAivIAv GRAPHITE Anonn Application mea August 25, 1930. serial No. 477,667.
One of the primary` objects of my inventionis to provide novel means for constructing an anode used 1n electrolysis of brine which has produced more rapid immigration of the chlorine and sodium atoms, which means low-V er voltage and more production and which will effectively withstand the action of the electrolyte and thereby give great length of service. v
Another salient object of my invention is the provision of a graphite anode arranged in a novel manner between a pair of depending electrodes, with novel means for connecting the electrodes to the anode so that the electrolyte can not affect said connecting means.
A. further important object of my invention is to provide an improved anode of the above character, which will be durable and efficient in use, one that will be simple and easy to manufacture, and one which can be placed upon the market at a low cost.
With these and other objects in view, the invention consists in the novel construction, arrangement and formation of parts, as will be hereinafter more specifically described, claimed`- and illustrated in the accompanying drawing, in which drawing Figure 1 is a side elevation of my improved device.
Figure 2 is a front elevation of the same showing parts thereof broken away and in section and illustrating the novel means employed for uniting the electrodes with the anode.
Figure 3 is a top plan view of my improved device.
Referring to the drawing in detail, wherein similar reference characters designate corresponding parts throughout the vseveral views, the letter A generally indicates my im- 5 proved device which comprises an anode 5 centered between a pair of depending electrodes 10 and 11. The anode 5 is formed from graphite in accordance with my invention, while the plates or electrodes 10 and 11 can be formed from any desired material. The
anode 5 includes an enlarged centrally disposed body portion 6, with` which' the electrodes or plates 10 and 11 facially abut and the upwardly extending reduced post 7. The p body 6 of the graphite anode 5 is provided 55I with horizontally extending spaced openings 8, which register with openings 12 and 13 formed in the upper ends of the electrodes or plates 10 and 11. These registering open- Y ings 8, 12, and 13 receive hard rubber sleeves 60y 14 through which extend the fastening bolts 15, the heads and nuts of the bolts are countersunk within the electrodes or plates 10 and 11 and the vcountersunk portions are filled with mestic or similar substance to pre- 6a: vent the brine from coming into contact with the brass fastening elements 15. lThe mestic is indicated by the reference character 16. The post 7, at its point of juncture with the body 6 of the anode 5 can receive a hard rub- '70 ber jacket 17, so as to protect the anode from the action of the brine or electrolyte. Y
My improved anode is particularly adapted to be used in gas cells with chlorine and sodium chloride. These cells are used and i5 equipped for use in a bleach plant in the manufacture of pulp for paper and other manufactured productions. The anodes, now in general use, quickly deteriorate and I have producedV a graphite anode that will 8d* have wearing quality several times greater than the anode now in general use.
Changes in details may be made without departing from the spirit or scope of this invention.
What I claim as new is:
1. A device of the character described comprising a central graphite anode including a body and a reduced post, electrodes having their extreme upper ends in facial abutment with the opposite sides of the body and depending therefrom for a material distance, .the body and upper ends of the electrodes provided with registering openings, sleeves of insulation tted in said registering openings, fastening bolts eXtending through the sleeves for connecting said electrodes to the anode, the terminals of the fastening elevments being countersunk within the electrodes, mestic covering the terminals of said loo fastening elements, and a jacket of hard rubber engaging about the post at the point of connection thereof With the body.
2. A device of the character described com- 5 prising a comparatively short centrally disposed anode, including a body and a reduced post formed of graphite, a` plurality of relatively long depending iiat electrodes arranged in parallel relation and projecting beyond 10 the sides of said anode, said electrodes having the eXtreme upper ends 'thereofi'in facial abutment with the o posite sides of the bodyk portion of said ano e, means conneoti'ng'the l electrodes and body portion together, andl 15 means for protecting said connecting means against the actonhof the electrolyte.`
i In testimony whereof I affix my signature.
