GABLE-CLAMPING DEVICE.

Specification of Letters Patent.

. Patented June 3, 1919.-

Application filed December 8, 1917. I Serial No. 206,206.

To all whom it may concern.

Be it known that I, WALTER T. GODDARD, of Victor, in the county of Ontario and State of .New York, have invented certain new and useful Improvements in CableClamping Devices; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of A for its purpose to provide a structure which can be economically manufactured and possessing the necessary strength and stiffness to withstand the usual strains to which it may be subjected. Still a further object of my improvement lies in adopting an arrangement which permits the device to be manufactured from sheet metal through a series of stamping operations. To these and other ends the invention consists in certain improvements and combinationsof parts, all as will be hereinafter more fully described,

the novel features being pointed out in the claims at the end of the specification.

In the drawings:

Figure 1 is a side'elevation showing my invention applied in operative relationship;

Fig. 2 is an enlarged side elevation of the clamping device;

Fig. 3 is a bottom plan View;

Fig. 4 is a vertical sectional view on line 4= -4t of Fig. 2; V

Fig. 5 is an end elevation, and

Fig. 6 is a plan view of the blank from which the clamp is formed.

Similar reference numerals in the several figures indicate the same parts.

For a general understanding of the application of' the invention, it is sufiicient to state that 1 designates an insulator support which is suitably attached to some'stationary element and suspended from the support is the clamping device to which is secured a conducting cable 2. v

I preferably employ a blank plate such as shown in Fig. 6, which is subjected to a series of stamping operations to obtain the form of device which is indicated in the re maining figures. Referring to Fig. 6, the portion 3 is bent outwardly along the dotted line 1, forming a curved flange 5 at the apex of the triangular opening of the plate or body portion, Fig. 2, which affords a bearing for the suspension member or support ing clevis 6. The portion 7 of the blank is bent outwardly to one side along the dotted line 8, affording a substantially flat flange 9 which is provided with bolt openings 10 for a purpose that will appear presently. The lower portion 11 of the blank is bent upwardly and outwardly along the dotted line 8, alfording a second flange at the base of the opening 12, extending in a direction opposite to that of the flat flange 9, -and is recessed or substantially Vshaped, afi'ording a seat 13 for the conductor 2. The body portion of the plate and also the opening 12 therein are preferably of substantially triangular shape, and the ends of the seat 13 ,are fiared downwardly at the portions ll,

so that if the conductor is broken on one side of the clamp, the remaining end willbe held by the clamp, which will swing partially about the clevis 6, and the surface 14 will afford a bearing for that portion of the cable portion 17 overlies the flange 9 and has a curved extremity 18 which engages the upper side of the conductor. The clamping member also preferably includes an integral lower portion 19 which may extend underneath the flange 9 and abuts against the same when the parts are in clamping relationship. The clampingmember is held rigidly against the conductor and against the flange 9 by means of bolts passing through openings in the flange 9 and in the clamping member and held in place by the nuts 20. The bolt heads 21 are preferably curved on their inner faces and engage correspondingly curved surfaces on the clamping member 17 in order to effect a tight engagement between the conductor and the clamping member, which latter is slightly resilient. When the nuts 20 are tightened, the lower portion 19 is held against the flat flange 9, preventing the clamping member from tilting, and retaining the conductor rigidly in the seat of the clamp.

The structure is an exceedingl practical and eflicient one, and economica to manu' edge of the opening to provide a bearing for a suspension member, a clamp support cable.

ing integral flange formed from the lower edge of the opening, a cable supporting integral flange formed with a seat to receive the cable, a clamping member for retaining the cable in its seat, and securing devices 00- operating with the clamp supporting flange and the clamping member for holding the latter in clamping engagement with the A cableclamping device comprising a plate or body portion, formed of sheet metal and having a substantially triangular central opening, an integral curved flange at the apex of said opening afiording a bearthe base of the opening forming a seat for a cable, an integral flange extending from the opposite side of the base of the opening, a removable clamping member consisting of a substantially U-shaped plate affording an upper portion which engages acable in'said seat and a lower portion which engages the under face of said flat flange,'and securing devices which hold the clamping member in engagement with the flange and the cable. '3. A cable clamping device comprisin body portion substantially in the form or a triangular plate, a bearing surface adjacent the top of the plate for engagement with a suspension member, a clamp sup orting flange adjacent the bottomof thepiate extending transversely of the latter, arable supporting flange also adjacent the bottom of the plate extending transversely of the latter and provided with a seat for the cable, a clamping member extending transversely of the plate and securing devices'cooperating with the clamp supporting flange and the clamping member to hold the latter in seatgfi- 4.-ZA cable clamping device comprising a clamping engagement with the cable in its substantially plane body portion having an opening therein, a bearing surface adjacent the topof the plate for engagement with a suspension member, a clamp up rti flange on one side of the plate, a cable supporting fiange on the side of the plate 0pposite the clamp supporting flangefand provided with a seat for the cable and-a clampingmember carried by the clampsupporting flange and extending through the 0pening in the plate to engage and hold the cable in its seat.

A cable clamping device comprising a body portion having an opening therein, a bearing portion adjacent the top of the body for cooperation with a suspension member, a cable supporting flange integral with the body and provided with a seat fonthe cable, an -integrai clamp supporting flange, a clamping member extending through the opening in the body, and securing devices cooperating with the clamp supporting flange and with the clamping member to hind tigp latter in clamping engagement with t e 'ca e.
