BUS-BAR SUPPORTING STRUCTURE.
. Application filed August 3, 1927. Serial No. 210,279.
comprises a minimum number of relative in expensive parts. I
A-further object of my invention is to provide a bus-bar-sup-porting structure wherein the supporting clamps are adjustable and may be used to accommodate bus bars of different dimensions without necessitating changes in the dimensions of the supporting structure. p
A further object of my invention is to provide a bus-bar support that is capable of supporting a number of bars less than the full I capacity of the support and that is capable of supporting a plurality of groups of bus bars in a hollow-square or hollow-polygon formation.
These and other objects that will be made apparent throughout the further description of my invention, are attained by means of the supporting structure hereinafter described and illustrated in the accompanying drawings wherein: p
Figure 1 is an elevational view of a supporting structure embodying features of my invention,
Fig. 2 is a side elevation of the supporting structure shown in Fig. 1,
Fig. 3 is a perspective view of a supporting frame, and
Fig. 4 is a perspective view of one of the clamps shown in Fig. 1, and. Figs. 5 to 9 are diagrammatical views illustrating some of the positions in which bus bars may be supported.
Referring to the drawings, the supporting structure comprises an insulating support 11 upon which a plate 12 is secured that is provided with threaded openings 13, the pur pose of which will hereinafter appear. Adjustable corner clamps 14, having clamping arms 15 and 16, are adjustably mounted on the plate 12 and secured thereto by means of screws 17 that are threaded into the openings 13 in the plate 12 the heads of the screws 17 being disposed in the counter sunk slots 18 in the arms 16. By reason of this construction, the clamp members14 may be moved toward and away from one another to accommodate bus bars of different widths or different numbers of the vertical bars.
From 1 to 3 bars may be used in any side of i frame 19 are provided with threaded openings 29 for receiving clamping bolts 31 that extend throughopenings 32 in corner clamps 33 which are provided with angularly disposed clamping arms 34.
As illustrated in Fig. 1, 4 groups of bus bars 35, 36, 37 and 38 are mounted on the support, each group of bars com rising 2 bars maintained in spaced relation y means of metal spacing blocks 39 that are disposed between the bars adjacent the points at which the clamp engages them.
In order to assemble a set of bars upon a. clamping structure the spaced group of bars 38 is first placed upon the arms 16 of the clamping members 14. The clamping members 14, which were previously securely fastened in operative position by means of screws 17, thus serve as a foundation for supporting the bus bars. After the bars of a group 38 have been properly placed in position, the frame member 19 is placed upon the uppermost bar, and bolts 27 are screwed into the threaded holes 26 a suflicient distance to loosely clamp the frame to the first group of bars. The vertically disposed groups of bars 35 and 37 are then placed in position and the bolts 27 securely tightened to clamp the groups of bars between the clamp arms 15 and the side sup orting faces 21 and 23 of the frame 19. he uppermost group of bars 36 is then placed in operative position upon the clamping face 22 of the frame 19. The clamps 33 are then assembled as indicated in Fig. 1, andthe bolts 31 are screwed into the frame, thus tightly clamping all of the groups of bars in assembled relation.
Bus bars having one to four groups 7 of bars may thus be accommodated by means of the clamping structure just described. Figs. 5, 6, 7, 8 and 9 illustrate the manner in which three or four groups of bars may be assembled upon the supporting structure Without alterations thereof. It is obvious that the groups of bars 38 may be supported alone or that groups 35 and 37 may be supported in combination. It is also obvious that three or more bars may be included in each group facture.
While I have illustrated but one embodiment of my invention, it will be apparent to those skilled in the art that various changes, modifications, substitutions, additions and omissions may be made in the apparatus illustrated without departing from the spirit and scope of my invention as set forth in the appended claims.
I claim as my invention:
' 1. A bus-bar-supporting structure compris ing a polygonal frame member having a plurality of angularly disposed bar-supporting faces and clamp members each for engaging two adjacent bars and for clamping them in assembled relation to the frame member.
2. A bus-bar-supporting structure comprising a polygonal frame member having'a plurality of angularly disposed bar-supporting faces, angular clamp members each for enamass? gaging two adjacent bars .and adjustable 4 means connected to the frame for drawing the clamp members into clamping engage ment with the said bars.
3. A bus-bar-supporting structure comprising a support member, a supporting frame having angularly disposed bar-supporting faces and clamp members each for engaging adjacent angularly disposed bars and securing them tothe frame, the said clamp members having means for securing them to the said support member.
4. A bus-bar-supporting structure comprising a support member, a supporting frame having angularly disposed bar-supporting faces and clamp members each for engaging adjacent angularly disposed bars and securing them to the frame, the said clamp members having means for adjustably securing them to the said support member.
5. A bus-bar-supporting structure comprising a polygonal frame member having aiplurality of angularly disposed bar-supporting faces, angular corner clamps each for engagingtwo adjacent bars and members threaded into the said frame member for drawing the clamps into engagement with the said bars.
6. A bus-bar-supporting structure comprising a polygonal frame member having a plurality of angularly disposed bar-supporting faces, angular corner clampseach for engaging-two adjacent bars and members extending between the edges of the said bars for drawing the clamps into engagement with the said bars.
In testimony whereof, I have hereunto subscribed my name this 26th day of July, 1927.
WALTER H. SCHRAMM.
