Specification of Letters Paten't.

Application filed January 31, 1906. Serial No. 298,801.

To (in/l w lw'nt 1'2: may concern.-

Be it known that LJOIIN H. SHAY, a citizcn oi the United States, and a resident of Wallace, in the parish of Saint John the Bap- ,tist and State of Louisiana, have invented a tion is to prevent the twisting and consequent interference between the skidding and outhaul lines.

A further object is to so construct the double block of" the carriage through which these lines .run as to prevent the lines chafing against each other.

Still a further object is to avoid the necessity of splicing the skidding line outhaul into.

the skidding line. Briefly stated, I attain'these objects by providing the double block with a peculiarly arranged idler sheave which is located between the two sheaves of the block and separates the skidding and outnaul lines. I also provide a peculiar swivel connection between the two lines and I interpose swivels into sections of the lines in certain peculiar positions so as to preventdisadvan-tagc from the twisting or turning of the lines.

7 The invention involves various other features of major or minor importance, all of which will be fully set forth hereinafter and particularly pointed out in the claims.

Reference is to be had to the accompany-v ing drawings which illustrate as an. example the preferred embodiment of my invention, in which drawings Figure 1 is a side elevation of the frame as a whole; Fig. 2 is an enlarged view showing the double block and portions of the skidding line and skidding line outhaul; Fig. 3 is a longitudinal section of the peculiar clamp employed on the skidding fline; "Fig. 4 is a cross section oi the same; and Fi 5 is a sectional view of a niodi 'ied form Oi iJlTG'SWiVGl.

indicates a skidding line, and 11 the sired to connect the outhaul. "chat this construction allows free outward skidding line outhaul, which are the same in general arrangement and function as in the prior patent to McKay above referred to. The double block to which these lines run is attached to the carriage 12, and comprises a shell 14, with the skidding outhaul sheave 15 and the skidding line sheave 16. Intermedate said sheaves is an idler sheave 17 which is smaller than the sheaves-15 and 16 and which serves to prevent interference between the two liues when said lines are slack. It has been found in the operation of the cableway that the twisting or turning of the cables tend to kink the same and prevent proper coaction of the parts. To remedy this defect I have interposed between the sections ofthe skidding line and skidding line oiitliaul swivels 18 and 19 which enable one section to turn or twist without imparting a corresponding turn to the other section.

The skidding line on thaul instead of bein spliced into the skidding line is connecte therewith by peculiar devices which will now be described: I

20 indicates a swivel attached to the end of the outhaul and connected to a sleeve orcollar 21 which slides loosely on the skidding line. This sleeve or collar is adapted to fetch up against the clamp which is fastened to the skidding line, and which, as shown, in Figs. 3 and 4, comprises two hall cylindric sections 22 connected to move freely toward and from each other, but to be incapable of independent longitudinal movement by means of pins 23 on one section fitting loosely in openings in the other section. The sections 22 are externally tapered and threaded and are adapted to screw into a correspondingly interiorly tapered and threaded thimble 24. The sections 22 embrace the-skidding line and the thimble 24 is screwed up over the sections, clamping them firmly to the skidding line at the point where it is do- It will be seen 2, and advance the skiddin line in the man ner fully set forth in the prior patent to. M0-

' and by Kay. In order to allow the swivel 18, and if I desired the collar ,21 and clamp 24., to run through the supporting block at the head tree of the system, I construct said block, the position of which is illustrated at 30 in Fig. l, I

with a sheave having an abnormally wide face and a shell corres ondingl arranged so as to accommodate the attac .ment to the skidding line, and enable them to be drawn readily-through the block. 1

Fig. 5'showsa peculiar swivel which not only may be used in place of the collar 21 and clamp 24, but which also performs the function of the swivel 18 on the skidding line. This peculiar swivel shown in Fig. comprises a socket piece 25'connected wlth the lnner section 10 of the skidding line, a socket piece 26 connected with the outer section 10? of the said line, and a socket piece 27 connected with the end 11 of the skidding line out-haul. I Within said socket sections 25, 26 and 27 are respectively engaged three heads 28 on a bifurcated connecting member 29. This arrangement not only joins the ends of the skidding line outhaul'to the skidding line intermediate the ends of the latter line, but also allows free turning of the skidding line I and free turning movement 'of the two sections of the outhaul line. These improveg ments avoid tangling and confusion f the two lines referred to, and allow free twisting. They further avoid weakening the skidding line by solici-ng'the outhaul line thereinto the emplo ment of the collar and connection between the clamp the point\o outhaul line and'the'skidding line can be I changed easily and fro uently without in any way injurin the ca les. The strength ofasteclcableis 'ecre'a sed about one-seventh by splicing a section'thereinto, and when the splice is taken out a decidedly weak section is left, which condition practically makes it impossible to change the point of connection between the two lines should such change be desired. My improvements also avoid chafing and confusion of the skidding line and skidding linqonthaul during the time they i are slack, the peculiarly arranged sheave- '17 of the double block separating the two lines, as explained. I

Having'thus described the preferred form of my invention, what I 1215 m ss new and desire to secure by Letters Patent is: i

1. A conveyor system having a skidding line, a skidding line out-haul, and a double block, the sheaves of which are adapted respectively to carry the skidding line and I skidding line outhaul, said block having an I idler sheave interposed between the two active sheaves of the block to prevent confusion of f the said skidding line h'aul.

2. A cable-wayhaving a skidding line, a

and skidding line outscenes skidding line out-haul, a block with two sheaves. located at different points along the length of the block, to carr the skidding line and skidding line outhau, and an idler sheave located intermediate the two first named sheaves, for the purpose s ecified.

A ca le-way having a skiddingline in .two sections, a swivel connection between the two sections, a skidding line out-haul, and a swivel connection between the two 'lines.

4. A cable-wayhaving a skidding line outhani in two sections, and a swivel connection 1liieltiween said sections, for the purpose speci- 5. A cable-Way having a skidding stop thereon, a skidding line outhaul, and means establishing sliding connection between the outhaul and skidding line, said means being adapted to fetch up against the stop.

6. A cable-way having a skidding line, a stop clamp adjustably fastened thereto, a skidding line outhaul, and'means establishing sliding connection between the outhaul and skidding lines, said means being adapted to fetch up against said stop clamp.

7. A cablc-way having a skidding line, a stop thereon, a skidding line outhaul, and means establishing sliding connection between the outhaul andskidding line, said means being adapted to fetch up against the stop, and said means including a swivel at the end of the skidding line outhaul.

8. A cable-Way having a skidding line, a stop clamp adjustably fastened thereto, a skidding line outhaul, and means establishing sliding connection between the outhaul and skidding lines, said means being adapted to fetch up against the said stop clamp, and said means including a swivel at the end of the skidding line outhaul.

9. A cable-way having a skidding line, a clamp adjustabl secured thereon, a collar sliding loose on' t 1e skidding line and adapted to fetch up against the clamp, a skidding line outhaul, and means connecting the outhaul with the collar. I

10. A cable-way having a skidding .line, a clamp adjustably sliding on the skidding line and adapted to strike the clamp, a skidding line outhaul, and 'a swivel connecting the end'of the outhaul with the collar.

In testimony whereof I have signed my name to'this specification in the presence of two subscribing witnesses.
