RALPH S. PEIRCE, OF CHICAGO, ILLINOIS.

METHOD AND APPARATUS FOR HANGING AERIAL CABLES.

Specification of Letters. Patent.

Application tiled February 27, 1905. Serial No. 247.490.

Patented July 3, 1906.

To all whom, t may-concern.:

Be it known that I, RALPH S. PEIRCE, a citizen ofthe United States of America, and

' a resident of Chicago, county of Cook, and

.l zinc, which serves not only as a fastening for the ends of the marlin, but also as a suitable member for engaging the messenger-wire or supporting-strand. This particular type of hanger was described in an application for Letters Patent iiled by mc ou the 27th day of February, 1905, Se'rial No. 247,489.

The present invention relates to the method of applying this and similar types of hanger in erecting aerial cables and also to certain apparatus necessary for carrying out this method.

I have illustrated my invention in the accompanying drawings, forming a part of this specification, .in which-M Figure 1 is a side view oll what I term a hanger-cartridge. Fig. 2 is a similar view of this cartridge with a number of cablehaiigers applied to it. Fig. 3 is a sectional View of the cartridge on the line 3 of Fig. 2 and looking in the direction of the arrow. Fig. 4 is a sectional view of the cartridge, taken on the line 4 of Fig. 2 and looking in the directiongo'ic the arrow'. This View shows clearly one of my improved hangers, as described in the above-mentioned application, in its relation to the cartridge. Fig. 5 is a general View in diagram, showing the method of using my invention.

The main portion of the cartridge is composed of as lit tube 1, having parts 2 and 3 fitting toget er, as best shown in Figs. 8 and 4. One end of this tube is provided with a bell-mouth 4 for facilitating the passage of the lead-covered cable into the tube. At `that end of the tube near thebell-.mouth is placed ia metal clamp consisting of the parts 5 and 6, secured together by the bolt 7 and suitable nuts. This clamp serves, primarily,-

*l porte der the metal 'clip 10 of the hanger the messenger-wire is-also passed. In order to have to bind the two halves 2 and 3 ofthe tube together, but also to clamp the tube .in proper relation to a rod 8, as clearly shown.

The hanger (best shown in Fig. 4) consists, 6o

as stated, in a closed loop of marlin 9, adapted to (pass twice around the cable to be sup- Within this loop' of marlin and unthe hanger assume the proper position with respect to the cable and the messenger-wire, itbecomes necessary to pass the ends of both messenger-wire and cable through the hanger,

this being true because the hanger is origi- 7o nally made in a fclosed loop. It is to facilitate this passing of the cable and messengerwire through the hangers that my cartridge is used. f

The cartridge, assembled as shown in Fig.

ing the metal I.clip 10 of the hanger in the- 85 same relative position that it will occupy with respect to the messenger-wire and cable after the `cable supported by it lis in place.

Referring now to Fil 5, the method of using this cartridge an its attached cable- 9o hangers will be made clear. Numerals 11 and 12 represent two telephone-poles, or instead o the pole 11 astud or post may be used. The messenger-wire 13 after being stretched throughout the length ofthe run of the cable..t.be-strung-is led down from the hanger 14lonithe pole 12 and passed through all of the metal clips 10 on the cable-hangers, therod 8, belonging to the cartridge, having previously been removed for this purpose.A roo The messenger-wire islthen secured to the pole or stud 11 several eet'from the ground by a cable-clamp 15 or in anyother suitable way. The reel 16, carrying the 'cable 17, is

then placed near the end of the messenger- :o5

wire, as shown, and the end 17 is passed into the bell-mouth 4 of the tube 1 and pushed entirely through the tube. The runnin rope or running-line 18, which has previous y been laid alongside of the messenger-Wire in I io the supports 14, is then securedto the end of the cable, and by it the cable is drawn slowly The tube 8o up the incline along the messenger-wire 13 and overthe entire length of the run.

As the cable is drawn throu h the tube 1 a man stationed at this tube sli es the hangers off of the tube and onto the cable at predetermined intervals. Each hanger then binds closely around the cable-sheath, and the clip 10 on the hanger slides up the messengerwire to the first pole and then along the horizontal portion of the messenger-wire.'

Where a length of cable is to be erected that would require more than the number of hangers that could be applied to one cartridge, then several cartridges are used, the cable end and messenger-wire being passed throu h all of them before starting to draw the ca le. -As soon as all the hangers on one of-the cartridges are exhausted then the tube which held them is taken otl" of the cable, which is readily done by virtue of the tube being split. The hangers on the next cartridgeare then used in the same manner.

The support 14 on the pole 12 is duplicated on all of the poles on which the cable is to be supported. This support is described by me in another application filed on the 27th day of February, 1905, Serial No. 247,491. 1t is of such a nature as to form a shoe or runway in which the messenger-wire and running-line may temporarily rest before the cable is drawn up and in which the cable rests while being pulled up. The cable and hangers slide through this shoe, the supportingsurface of which is polished to prevent undue friction.

I do not wish to limit myself in all respects to the exact details of the invention here shown and described, as modifications may be made which will lie Within the scope of my invention.

What I claim as new, and desire to secure by Letters Patent, is-- 1. in a device for erecting aerial cable, a plurality of cable-hangers having members for embracing the cable, and adevice for holdinfr said members in alinement to allow the cable to pass through them, substantially as described.

2. In a device for use in erecting aerial cable, a cable hanger supportin appliance having an opening throu h whic the cable may pass, a plurality of ca le-hangers having members for embracing the cable, said hangersupporting appliance serving to hold said cable-hangers in alinement, substantially as de- 55 scribed.

3. In a device for use in erecting aerial cable, a plurality of cable-hangers having cable-supporting members, and an appliance for holding said cable-supporting members in 6o alinement to allow the cable to pass through them, substantially as described.

4. In a device for use in erecting aerial cable, a tube through which the cable may pass, and a plurality of cable-hangers having 65 members for embracing the cable, said tube extending through said members, substan tially as described.

5. In a device for use in erecting aerial cable, a tube through which the cable may pass, 7o a 'plurality of cable-hangers having loops of flexible supporting-cord for embracing the cable, said loops being passed around said tube, substantially as' described.

6. In a device for use in erecting aerial ca- 75 ble, a longitudinally-divided tube through which said cable may pass, a plurality of cable-hangers having loops of flexible supporting-cord for embracing said cable, metallic clips on said hangers for embracing the So strand for supporting said cable, and means for holding said clips in that relative position with respect to the tube, that they will bear to the cable when supported upon Athe messenger-wire, substantially as described. -8 5 7. ln a cartridge for use in erecting cables on messenger-wires, a tube through which the cable may pass, and a rod secured in a position parallel to said tube and occupying the same relative position with respect to the 9o tube as does the messenger-wire with respect to the cable which it supports, substantially as described.

8. In a cartridge lor use in Stringing cables` 0n messenger-wires, a longitudinally-divided 95 tube through which the cable may pass, and a rod secured in a position parallel to said tube and occupyingr the same relative. position with respect to thc tube as does the messenger-wire with respect to thc` erected cable, roo

substantially as described.

Signed by me at Chicago, county of (look, State of Illinois, in the presence ol two witnesses.
