signor to Burndy Engineering Company, Inc., a corporation of New York Application August 12, 1942,. Serial No. 454,621
Claims. l vThis invention relates to improvements in bus `support-clamps for supporting electrical conductors, and more especially, bus support clamps for fla-t electrical conductors designed to be mounted on an insulator support.
Flat bar conductors are generally used either singly or in multiple and mounted with their wide faces in a vertical plane. For example, a popular sizeof flat bar is 1A, thick by 4 wide and it is frequently used either singly or in multiples of 2, 3 or 4 with the wide faces parallel to each other and 1A apart. The group of iiat bars are generally mounted on the conventional insulator and the usual position of the bars relative to the insulator provides for the bars crossing the top or cap of the insulator with the longitudinal centerlines of theV bars and insulator mutually perpendicular. The Wide faces of the bars are generally parallel to the longitudinal centerline of the'insulator.
It is a distinct advantage to provide a support clamp that may be adjusted to take a wide range in the number and thickness of the flat bars Without change of parts. It is one object of this invention to provide such an adjustable feature.
Another object of this invention is to provide a bus support clamp which will permit of lateral adjustment of the bus with respect to the insulator. This is advantageous when the centerlines of a row of insulators on which the bus is to be mounted are slightly out of line.
Other objects are to provide a bus support clamp having transverse rails to permit the clamping elements to be adjustably positioned thereon; to provide adjustable clamping elements which project a minimum distance beyond the walls of the clamping elements; and to provide angular as well as transverse adjustments of the clamping elements.
I accomplish these and other objects and obtain my new results as will be apparentfrom the devices described in the following specification, particularly pointed out in the claims, and illustrated in the accompanying drawings, in which:
Fig. l is a partially sectioned top View of one form of my device.
Fig. 2 is a side view of the same..
Fig. 3 is a partially sectioned end view.
Fig. 4 is a perspective view of one of the clamping plates.
Fig. 5 is a partially sectioned top view of a modification thereof.
Fig. 6 is a partially sectioned side view oi the same.
Fig. 7 is an endview.
Fig. 8 is a perspective view of one of the clampingy plates of my modification. Fig. 9 is a partially sectioned top view o1'l another modication.
Fig. 1-0 is a partially sectioned side view of the same.
Fig. 1.1V is an end view.
Fig. 12` is a perspective view of one of the clamping plates thereof.
Referring more particularly to the drawings, reference numeral 9 in Fig. 2- indicates the top or cap of an insulator upon which my clamping device is normally mounted. The bus-clamping device, in the form shown in Figs. 1 to 4, consists primarily in the base element I0, and two lateral clamping elements 20, all held together by various bolts, as will be hereinafter described.
The circular base element II) is provided with four angularlyl elongated apertures I3, through which` are inserted the insulator bolts I4, provided with` heads I5.. which lock` the base IIl to the insulator cap "9. The elongated apertures I3 enable the clamping elements to be rotated on the insulator cap to obtain proper alignment thereof.
The base I0 is also provided with a transversely extending rail` section I6 formed integrally therewith, which is hollowed at each end thereof as at I`I, to allow the bolts I8 to project therethrough. The` base is hollowed as at I9 to reduce its Weight.
The clamping elements 20, shown' in perspective in Fig. 4` are two in number, and identically formed. One face 2| is flat for applying pressure to the bus-bars 22 and the intermediate spacers 22a, and the other face 23 is rounded to give additional strength. Four extending ears 24 are provided with apertures 25 for insertion of the bolts II, which lock the two clamping plates 2l) together about the bus-bars by means of nuts I2. A-t the base of the clamping plates, a channel 26 outwardly extends, which rides the rail section I6 of the base member I0. A slot 21 is formed in the upper side of the channel 26, to provide for the insertion of the bolt I8, which locks the channel to the base rail section by means of the nut 28. The clamping plates 20 are hollowed outI as at 29 to reduce the weight thereof.
This embodiment of my' device is characterized by the employment of base rails which cause the clamping plates to be maintained in parallel position, yet transversely adjustable to accommodate varying sizesy and numbers of bus-bars and intermediate spacers.
In Figs. 5 to 8, I have shownY a. modified form of my device. Reference numeral 4I) designates the base section, and 50 the clamping members. The base section 40 containsv four angularly elongated apertures 4I, .through which are inserted the insulator bolts I4, provided with heads I5 for locking the base II0` to the insulator cap 9. The base 40 is provided with two longitudinally extending sections 42, each having transversely elongated apertures 43. The underside of the lextending with a. flxedly positioned cap or plate member,
said bus 'support comprising a movable upper yplate member angularly adjustable with respect y to the fixed plate member of the insulator and in Each member is provided at its four corners withLJzextending ears 53, each ear apertured as at 54 to receive the bolts 55 which lockthe two clamping members to each other by their corresponding nuts v56. One ear adjacent the lower portion is provided with a base extension 51 which terminates in an inwardly extending right angle lug 58, perforated at 59 to accommodate the bolt 44 of 'the base section.
Each clamping member has its inwardly extending right angle lug locked to the base member by means of nut 45 threaded to base bolt 44.
The transversely elongated apertures 43 in the base member 40 permit the two clamping members to be spaced to satisfactorily accommodate the proper number and thickness of bus-bars and intermediate spacers 46 and 41 respectively.
This modication thus discloses means for the angular adjustment of the base section, and the transverse adjustment of the clamping members. In addition, there is provided transverse adjusting means which does not extend beyond the curved outer walls of the clamping members, thus reducing the lateral dimensional requirements, Where compactness is important.
In the modification shown in Figs. 9 to 12, the clamping members are each provided with two supporting inwardly extending legs, where greater structural strength is necessary. Here the base member 60 is attached to the insulator cap 9a by insulator bolts 14a through angularly elongated apertures 6I and locked thereto by nuts 15a. The longitudinally extending base portions 62 are each provided with a pair of inwardly extending elongated apertures 63 for the base bolts 64.
The clamping members 10, two in number, are each provided with flat; and round sides, 1l and 12 respectively, and corner ears 13, apertured as at 14 to receive the clamping bolts 18 locked to- 1 gether by nuts 19. The lower ears have extensions 15 with inwardly extending right angle lugsl 16 apertured at 11 for receiving the base bolts 64, which are locked thereto by nuts 65.
By the foregoing constructions, I have in each instance retained the angularly adjustable base member, and the transversely Vadjustable clamping members. In addition, I have disclosed means for providing the lateral adjustments having the necessary structural strength with minimum dimensional space requirements.
I have thus described my invention, but I desire it understood that it is not confined to the particular forms or uses shown and described, the same being merely illustrative, and that the invention may be carried out in other ways without departing from the spirit of my invention, and,
therefore, I claim broadly the right'to employ allv equivalent instrumentalities coming within the scope of the appended claims, and by means of which, objects of my invention are attained, and new results accomplished, as it is obvious that the particular embodiments herein shown and described are only some of the many that can be employed to attain these objects and accomplish these results.
