HOWARD 0.11001 and citizens of the United of Philadelphia, Penn- Be it known that we,

States, and residents sylvania, have inventedcertain Improvements in Devices for Suspending Electric Gables, of which the following isa specification.

The object of our invention is to construct a device for effecting the rapid and secure attachment of electric cables to overhead wires; and this object we attain in the manner which we will now proceed to describe, reference being had to the accompanying drawings, in whicha Figure 1, Sheet 1, is a side view of thedevice; Fig. 2,,a view of the end of looking in the direction of the arrow, Fig. 1;

Fig.3, Sheet 2,

with lead pipe,

a plan view; and Fig.4, alongitudinal section.

In carrying on telephone-exchanges in large citiesit has been found necessary to use large and heavy cables, each containing a number of wires, the cables being. frequently covered so that they are exceedingly and their proper support has been the The plan'now usu- 3 ally adopted is to first stretch a suspensionwire, and then to'hang the cable upon this Q a rapid and effective manner.

wire; and our invention has reference to a simple device for accomplishing this objectin In the drawings, .A represents a block,

. i throughwhich extends an opening, a, the block being divided horizontally through the center of this opening, and the two halves being held in place by a bolt, 1), adapted to staples d, which project from the lowerhalf of the block through openings in the upper half, the bolt being preventedfrom being accidentally displaced by means of a spring-plate, e, which engages with 2. lug, e, on the upper half of the block, this plate, however, being readily freed from engagement with the lug when it becomes nec- GSSELIX to remove the bolt and separate the sections of the block, for

a purpose described hereinafter.

l At the front end of the block A are bearlugs for the shafts or spindles of a grooved drum, B, and grooved roller D, and at the rear end of the machine is a sleeve, F, adapted to the same,

. tion on the rear end of the rotate upon the block, which is made of circularform at this pointfor the reception of the sleeve, the latter'being retained longitudinally tates a rotating movement will be imparted to 60 the sleeve F.

On the sleeve F are two radiallyprojecting arms, 70, each of which is slotted for the reception of a threaded stem, 19, on the spindle of a spool or bobbin, G, a nut, the stem, so as to secure the spindle to the arm in any desired position. In the present instance we have shown only one spool; but each of the arms may, if desired, carry a spool; or

one of the arms mayhave an adjustable weight 7 to act as a counter-balance for the spool as the sleeve F rotates.

The operation of the device is as follows:

The wire as having been properly secured to its supports and the cable same at one end, the two-part block is applied to the wire and cable, so that said wire and cable will pass through the opening a and between the drum B and roller D, as shown in 8, being adapted to 6 y attached to the 7 5 Fig. 4. The sleeve F is then secured in posi 8c block, and said block is drawn along the wire 00 in any suitable manner. The cable, which is drawn from areel in the street or on an adjacent housep,

tary motion is imparted to the drum and its shaft, which motion is transmitted through the medium of the gearing to the sleeve F, the rotation of which on the block causes the fine wire or wrapping from the spool G to be wound around the wire 00 and cable, y, thus firmly binding the said cable to the wire. Whenthe block reaches a point where the wire .10 is secured to a support the sleeve F is removed, and the halvesof the block are. separated, the

ble in advance of the fastening.

bears firmly upon the drum B, and as the 85 latter is moved along beneath the cable a rodevice being again applied to the wire and 0a We have shown the sleeve F as being made.

in halves hinged together and secured by a mo 7 pivoted bolt and nut; but this is not essential, as the sleeve might be slipped longitudinally from the block on loosening theset-screws f. The plan shown, however, is more expeditious and is preferred.

Instead of relying upon the friction of the cable upon the drum 1% to efiect the rotation of the sleeve F, we may impart a positive movement to the latter. For instance, a drum, J, may be hung to hearings on the under side of the block A, as shown by dotted lines in Fig. 4, the shaft of this drum carrying the spur-wheel g, which gears into the pinion h, and a cord or wire, w, being wound around the drum and secured to any fixed object at its outer end, so that as the block is drawn along the wire 00 the said cord or wire 10 will be unwound, and the drum J will-be rotated.

, We claim as our. invention '1. The combination of the block A, having an opening and grooved guides for the supporting wire and cable, a sleeve, F,.carrying one or more spools, G, and capable of rotation on the block,'a driving-drum on a transverse shaft, and gearing, substantially as described, whereby the movement of the drum is transmitted to the sleeve F, as set forth.

2. The combination of the block A, having an opening, a, the sleeve F, adapted to rotate on the block, the drum B, grooved for the re ception of the cable, and having a transverse shaft, and gearing whereby the sleeve F is driven from the drum-shaft, as set forth.

3. The combination of the block A, made in two parts detaehably secured together, and having an opening, a, the sleeve F, having a pinion, n, and also made in two parts detachably' secured together, and gearing carried by the block and engaging with the pinion 'n, as

set forth.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
