GEORGE A. AMSDEN, OF LITTLETN, MASSACHUSETTS, SSIGNOR TO THE LA'MSUN LAVSUN CONSLIDATED STORE SER''CE COMNYQ 0F BOSTON, MASSACHUSETTS, A CURPORATION OF NEX/V JERSEY.

oannnc'enninn .arrenerns T QU fr0/ront it may concern y Bo it known that I, Grenen A. Aisnmr, Vf ALittleton, in the county of ltfiiddlesex and State of ldassachusctts, have invented certain new and useful Improvements in Cable? "traverse the bends and pass the idlers and pulleys supporting the cable without danger of throwing the carriers out of engagement with the cable and without necessitating the changing of the position of the carrier.

ln the accompanying drawings is illustrated a construction embodying my invention in which- Figure 1 is an elevation of a 90 degree bend comprising the corner of a cable carrier apparatus and showing a carrier trav-v ersing the same. is an end view vof Fig. 1 showing the track broken awayl on line Q looking in the direction indicated by the arrow. Fig. 8 is an enlarged view of a portion of one of the idlers or supporting pulleys showing the position of the cable and carrier while traversing the same. Fig. l is a sectional view through the center of one of the idlers.

Like characters of reference refer to like parts throughout the several views.

A and B represent respectively the outgoing and in-going tracks upon which the carrier is adapted to travel. The tracks B at the bend are supported by the corner brackets D in which is journaled the idler or supporting pulley E which supports the iii-going portion of the driving cable C. The tracks A are supported at the bend by the corner bracket F in which is liournaled the supporting pulley or idler G which sup ports the out-going portion of the driving cable C. The brackets D and F are supported in relative positions by the bent rod or shaft H which forms a fixed shaft upon which the idlers E and G rotate. The idlers are constructed with a central peripheral flange J which divides the pulley into two separate grooves P and L, see Figs. 3 and ll, one of which the cable normally traverses.

Then a carrier is being transmitted by Specification of Letters Patent.

the cable and arrives at one of the turns or bends as shown in Fig. 1, the jawn1 N and l which comprise the spring clamp of the can rier, are engaged by the sides of the grooves Pand L respcctively, retaining the cable C within said clamp and causing the cable to ride upon the peripheral flange l which also prevents the cable from being thrown out of the grip of the clamp, see Fig. 3. After the carrier passes the idl ers and rounds the bend, the cable drops back to its normal position in either of the grooves P and L.

l do not limit myself to the construction herein. shown as the peripheral flange J may be dispensed with forming a single groove pulley and leaving the wedging action of the jaws N and K within 'the groove of the pulley to enable the carrier to make the turn without dropping the cable.

Having thus described my invention and set forth a construction embodying' the same what I claim as new and desire to secure by Letters Patent of the United States is:

1. in a cable carrier apparatus, a track or way, an actuating'cable for driving carriers along said track or way, a carrier having a clamp comprising opposing aws one at least of which is resilient, said jaws adapted to be resilientlyy clipped onto said cable, pulleys for supporting said cable, and means for momentarily locking the jaws of said clamp to prevent the resilient opening thereof and consequent disengagement of said cable therefrom when the carrier passes said pulleys.

2. In a cable carrier aparatus, a track or way, a carrier adapted to travel on said track or way, a cable for driving said 'carrier, a. spring clamp comprising opposing jaws, one at least of which is resilient, lo-

:ated on said carrier and adapted to be clipped into engagement with said cable, and a pulley located at a bend and adapted to support said cable, said pulley carrying a central peripheral 'liange thereon adapted to hold said cable securely between the jaws of said clamp when said carrier is passing said bend.

3. Cable carriei` apparatus comprising a track, a carrier to travel thereon, a cable for driving said carrier, said carrier having means to engage said cable, a pulley about which said cable normally passes and around which said carrier is drawn by said ealile, "and means, independent el the earrier and its cable engaging means, te directly engage said Cable and aid in retaining itin place in said cable engaging means Wlien said cable is pulled away from the vsurface of said pulley by the passage of said carrier tliereareund,

1l. Cable carrier apparatus Comprising a track, a carrier to travel diei-een7 a ealale fer driving; said Carrier, said carrier having means te engage said cable, a pulley aloeut .which said Cable normally passes and areund which said Carrier is drawn lay said cable, means, carried by said pulley :lf-e1 direeely engaging said cable and fer alsa eugaging the ealole engaging means ei' said carrier, to retain said cable in place i said ealile engaging' means when j@lie Cable is pulled away from the surface el the pulley ay the passage of the carrier tliereareund.

ln a cable carrier apparatus, a track er way7 a Carrier adapied'kto travel en said track er Way, a ealole for driving saideari'ier, a spring clamp comprising` opposing; jaws, one at leash ei" which is resilie' lg located on said carrier and adapted te engage said Cable, and pulleys er idlers located at the bends in said Way and adapted te support said cable, eaela of said pulleys er idlers carrying a Central peripheral 'liange thereon adapted te lield said cable securely between the jaws oi: said clamp When said carrier is passing' said bends, each el: said pulleys also being provided with Hang s to engage the jaws ol 'Clieearrier and held ythem clamped on the Cable when said Carrier is passing` around' a pulley.

6. Cable Carrier apparatus Comprising a track, a carrier to travel diei-een a cable for driving` said carrier, said carrier having means to engage said cable, a pulley about which' said cable normally passes and around Wliieli said carrier is drawn by said cable7 and means,'independent oi' the ear .rier and its cable engaging means, to directly engage said Cable and aid in retaining it in place in said cable engaging means when said ealile is pulled away irem the surface ef 'said pulley by the passage of "Peer engage said Cable substantially at tlie peint.

Where it is by said 'arip "alien said Carrier' is traversins' a laendvin said traelg and enacting means te engage at least a part ef said grip at suela times, said last tive mentioned means adapted te prevent said cable ifrem springing nul, eil said grip at said bend.

ln testimony whereof, l have signed my name te 'this applieaion in the presence oi' tive subseril'iing Witnesses, this ltlrday oi Sept. 1912. f
