VAPOR-RECTIFIER.
Specification of Letters Patent.
Patented Dec. 28, 1915.
Application filed March 80, 1914. Serial No. 828,182.
To all whom it may concern:
Be it known that I, Gnonon M. EATON, a citizen of the United States, and a resident of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Vapor- Rectifiers, of which thegfollowing is a specification.
My invention relates to mercury vapor rectifiers, and particularly to means for supporting the shielding members which are employed therein to prevent short-circuit ing between the anodes.
he purpose of my invention is to provide a structure which may be quickl and easily constructed and assembled, whic will rigidly support the shield, and at the same time insulate it thoroughly from the con-v tainer.
In the accompanying drawing, Figure 1 is a view of my shield support, partially in section and partially in elevation; Fig. 2 is an exploded perspective view of the main member of my support, together with one of the bolt-insulating devices; Fig. 3 is a sectional view of the bolt-insulating device, and Fig. 4: is an end view in elevation of the same member.
The metal cover of a mercury vapor rectifier is shown at 5, carrying an anode 7,
and insulated therefrom by an insulating bushing 8. In order to protect the anode from short circuits and other improper arcing, it is surrounded by a cylindrical shield ing member 9, preferably of metal. In order to support the shield 9, I provide a ring shaped member 6 of some refractory insulating material, such, for example, as porcelain and provided with several equally spaced openings 10. Seated in the openings 10 are bushings 11, each of which is provided with a shoulder 12 and with a flange 13 dependent therefrom. The bushings are each flattened on their exterior surfaces, as shown at 14, and these flattened portions are adapted to coact with similar flattened portions 15in the openings 10 so that the bushings are restrained from turning in the openings. The shield member 9 is provided with a flange 17 at its upper end, the flange being co-extensive in width with the lower face of the member 6, except at the openings 10, where it is notched away, as shown by the dotted lines 1818 in Fig. 2. In assembling the device, the
member 6 is placed against the lower face of the cover 5, the shield 9 is placed a ainst the lower. face thereof, as shown by otted' lines 18, the bushings 11 are inserted in the openings 10, the shoulders 12 engaging flange 17 and the bolts 16 are then inserted through the bushings ll-and screwed into the cover 5, thus holding the entire assemblage firmly .in place. In order to prevent the fracture of the vitreous members,- by reason of expansion and contraction, a compresslble locking washer 19 is the heads-of bolts 16.
placed under The shield-supporting means above de- 1. An insulating support for an electrode shield comprising a ring-shaped member of insulating material, supporting means therefor, and insulating means for the supporting means, a portion of the shield being clamped between the insulating means and the ring-shaped member.
2. An insulating support for an electrode shield comprising a ring-shaped member of insulating material having upper and lower bearing surfaces, bolts projecting through spaced openings therein, insulating bushings for the said bolts having exterior lugs, a portion of the shield being clamped between said lugs and the ring-shaped member.
3. An insulating support for an electrode shield comprising a ring-shaped member of insulating material having upper and lower bearing surfaces, bolts projecting through spaced openings therein, insulating bushings for the said bolts having exterior lugs, and depending flanges to screen the bolts from the shield.
4. An insulating support for an electrode shield comprising a ring-shaped member of ings for the said bolts having. exterior lugs, a portion of the shield being clamped between said lugs and the ring-shaped member, said insulating bushings being located in notehesin the shield, so that the latter is positivelyprevented from rotating with respect to the electrode.
In testimony whereof, I have hereunto subscribed my name this 26th day of Man,
GEORGE M. EATON.
