:FRANK E. GET'I'S, OF CHICAGO, "ILLINOIS, ASSIGNOR TO ELECTRICAL ENGINEERS EQUIPMENT COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.
BITS-BAR INSULATOR AND SUPPORT.
Specification of Letters Patent. Patented J uly 17, 1917.
Application filed Jiily 31, 1916. Serial No. 112,236.
To all whom it may concern:
Be it known that I, FRANK E. GETTS, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Bus-Bar Insulators and Supports, of which the following is a full, clear, concise, and exact description,
reference being had to the accompanyingdrawings, forming a part of this specification.
My invention relates to busbar insulators and supports.
In the construction of switching and distributing boards it is necessary to carry common busbars to a number of points upon the insulating board or slab in such manner as to secure complete insulation from the grounded framework or other supporting means, and at the same time secure good mechanical support to insure permanence and security. I
The object of the present invention is to provide an insulating support such as may be employed for supporting busbars or the like. One particular point of novelty which I wish to emphasize is the use of an internal reinforcing member for the porcelain or other friable material which constitutes the body of insulation.
Other features of novelty will be apparent to those'skilled in the art from the following description;
In the accompanying drawings in which I have illustrated one modification of my inventi.on
Figure 1 is a front elevation with parts broken away; and
Fig. 2 is a plan view of the same.
The device which I have shown comprises essentially a body of insulation 1, which is provided with a corrugated surface in order to make the creepage distance greater. This body 1 forms the insulator proper and in general contour is a cylinder or frustum of a cone having an upper fiat radial base 2 and a lower fiat radial face 3. The insulator 1 is provided with an axial recess 4 the interior surface of which is provided with suitable corrugations 5 which permits the cementitious or binding material 6 to insure a firm grip upon the interior surface of the recess. The insulator 1 seats upon a base plate 7. The base plate 7 is provided with a flat bottom to permit it to seat solidly base plate 7 is cored out as shown in Fig. i
l, leaving however the axial boss 11 which is screw threaded to receive a. short section of rod 12 that projects up into the cavity or recess I in the insulator 1. The rod 12 is provided with peripheral notches 13 for permitting the cementitious material 6 to secure a firmer hold upon the same.
The lower part of the insulator is provided with a groove 14 adjacent the radial face 3 and in a similar manner the base plate 7 is provided with a peripheral groove 15. A split clamp 16, which embraces the adjacent edges of the two parts, has suitable flanges fitting into the grooves 1 1 and 15 serving to clamp the two parts together. A filling of cement 17 or the like may be employed between the adjacent parts and the split clamps 16.
A metal supporting block 18 rests upon position by means of a split clamp 19 which has-flanges seating in the grooves 20 and 21 for holding these two parts firmly in engagement. The clamping block 18 is provided with symmetrically projecting ears or lugs 22 shown in this particular case as four in number. A clamping member 23 of generally rectangular form is provided with suitable lugs 2% which register with the lugs 22 and form suitable means for reception of the bolts 25 which hold the clamp and block together. The flat busbar 26 is gripped between the clamp 23 and the block 18 by means of these bolts. It is obvious that the busbar 26 can be passed between the clamp 23 and the block 18 in a direction at right the top face of the insulator 1 and is held in l v 19 is opened, smeared with smooth-on-and then applied and clamped against the adjacent parts to hold them firmly in position.
While I have described my invention with considerable particularity, I wish it to be understood that I do not intend to be limited to the precise and specific details of construction except as the same are set forth in the appended claims, as I consider the device. capable of modification and variation in proportions and dimensions.
I clalm: 1. In comblnatlon a clrcular base plate having a flat radial face, a reinforcin proje'cti'on extending axially from said ace, a body of insulation having a radial face and having an axial recess for receiving said reinforced projection, said body of insulation having a peripheral groove adjacent said radial face and said base plate having a similar peripheral groove adjacent its radial face and an encircling clamp having portions adapted to lie in said grooves to clamp said body and said base plate together.
2. In combination, a circular. base plate having a flat radial face, said base plate having means for clamping the same to a support, a reinforcing projection extending axially from said face, said projection comprising a short rod screwed into said base plate, said rod having notches cut in the side wall thereof, a body of insulation having a radial face and an axial recess for receiving said reinforcing rod, the interior face of saidre cess being roughened, a fillin ofcementitious material between the wa ls of said recess and 'said rod, said body of insulation having a peripheral roove adjacent said radial face and said ase plate having a similar peripheralgroove adjacent its radial face, and an encircling clamp havingv portions adapted to lie in said grooves to clamp said body and base plate together.
3. In combination, a base havin a plane radial face rovided with an axifi pro'ection, an insu ating body having a radial ace provided with an axial opening to receive said projection, said projection and opening having annular recesses toserve as holding means for cement or the like, said base plate and insulating body having annular grooves adjacent their adjoining faces and clamping means engageable with said grooves to reinforce the insulator.
, 4. In combination, an insulating conductor support comprisin a non-conducting body having a recess t erein, a base plate having a reinforcing projectlon to seat in said recess, a conductor block carried by the body, said body, plate and conductor block having peripheral grooves and a'plurality of clamping elements having flanges to engage in said grooves and rigldly connect said body, plate and conductor block.
5. In combination, an insulating conductor support comprising a base plate havinga peripheral groove and a reinforcing projee tion, an insulating supporting body having a plurality of parallel peripheral grooves along the outer face thereof and a longitudinal recess to receive said projection, a conductor block receivable on the free end of I said body, and provided with a peripheral groove, means to secure a conductor to saiding anges engageable in the peripheral grooves in said body, face plate and conductor block. 7
6. In combination, a conductor support comprising a base plate, a non-conducting block and a pair of clamping members havbody havlng peripheral grooves and a longitudinal recess opening at one end thereof,
said base plate having a reinforcing column to engage in said recess, a conductor block, having a peripheral groove, and clamping means to engage the grooves in said base plate and clamping block andthe .endmost grooves of said insulating body.
In witness whereof, I hereunto subscribe my name this 25th day of July, A. D. 1916.
