FALL-ROPE CARRIER.

Specification of To all whom it may concern.:

Be it knownthat we, JAMES G. DELANEY and Asnnn LAMBERT, citizens ofthe United States, and residents of Newark, in the county of Essex and State of New Jersey, 1 have invented a new and Improved Rope- Carrier for Conveyers or Cableways, of which the following is a full, clear, and exact descri tion. 1o A T e invention relates to anovel device for, supporting the operating rope or ropes of an overhead conveyer.

This application is a division of our applicationfled March 18, 1904, Serial No. 198,769.

The present invention lies in a novel arrangement of the traction-roller by which We are enabled to gear down the speed ofthe rope-carrier with respect to that of the haulrope.

This specification is a specic description of one form of our invention, -while the claims define the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part of this specica- 2 5 tion, in which similar characters of reference indicate corresponding parts in all the views.

`Figure 1 isa side view showing the general plan of the conveyer system. Fig. 2 is an enarged side elevation of the rope-carrier, and

3o Fig; 8 is a corresponding end view thereof.

Fi 1 shows, with the exception of the novelrope-carrier, an ordinary overhead oonveyer system embod g the towers or supportsa, the main cab e b, the haul-rope c and its drum ,and the fall-rope ewith its drum jl g indicates the load-carrier, supported on the main cable inthe usual manner. The rope-carrier has a frame or bodyv which may be of any form desired, but is preferably con- 4o strueted of two cheek-plates 7L, connected by stay-bolts h and clamps h or by other equiva- `lent means. Said body is supported lon the main cable by rollers n. The fall-rope e runs on a sheave or supportin -roller fi, mounted in the lower part of the ody h and is sustained thereby in the usual manner.

The' traetionlroller comprises two faces 7c and l. The face c engages the under side of the main cable 1J, while the large face l lies Vat 5o one side of the main cable, projecting above and laterally beyond the same in the manner indicated in Fig. 3, and said large face l engages the haul-rope c. The traction-roller is mounted to be free--that is` to say, to move 5 5 vertically between the cables-for a urpose which will hereinafter appear. As e haul- Letters Patent. Patented Aug. 28, 1906. p

rope runs under the large face l of the traction-roller it causes said roller to rotate, and the action ofthe small face k on the main cable b causes the carrier to be moved bodily along said cable. According to the ratio indicated in the drawin run onthe main cab e b at approximately one-fourth the speed of the benl-cable. 1t is obvious that by varyi g this ratio the speed may be varied accordingly.

It is necessary to'keep the cables b and c en aged with their respective roller-faces wit sufiicient firmness to insure efficient traction, but it is also advisable to m'ake this engagement yielding sufficiently to prevent destructive strains on the parts. We attain this end lby means of two sheaves m,which are mounted to be vertidally ad'usted in the framing of the rope-carrier an which beatl on the under side `of theihaul-rope, so as to bow'the haul-rope sli htly around thel large kface of the tractlon-ro ler, the traction-roller engaging the concave side of the bowed portion of the rope. In this manner the elasticit ofthe haul-rope, which is usually of stee is utilized to ress the traction-roller yieldingly against t e main cable, bringing aboutthe flexible engagement which is necessary between these points rather than .a

would 'prematurely destroy t e parts and increase the friction incident to their operation. It willbe observed that the rollers m and n bow in the haul-ro e the traction-ro ler will tend naturally to eep this osition, but it may be held from horizonte. movement by means of a .pin o, which fits in a vertically-extending slot ha in the frame of the ro e-carrier. This slot allows the free vertice movement of the traction-roller as it will occur during the Working of the ap aratus within the limits of the flexibility of t e cables IJ and c; By this arrangement we cause the cables la and c to engage the traction-roller with-.a firm and uniform pressure, which pressure is at the same time sufliciently elastic lto give perfect traction and avoid premature destruction of arts.

Various o anges in the form7 proportions and details of our invention may be resorted to at will without departing from the spirit thereof. 'Hence we consider ourselves entitled to all such variations as may lie within the intent of our claims.

In a conveyer, a rope-carrier comprising a frame, a free traction-roller, having a large and a small diameter, the small .diameter being adapted to engage its face with the conveyer main cable and the large diameter being adapted to engage its face with the conveyer haul-rope, ancI means adapted to engagethe said l1aul-rope at opposite sides ofthe vertical center of the tractionroller, whereby to bow the haul-rope slightly around the traction-roller and yieldingly press the roller against the main cable.

2. In a conveyer, a rope-carrier comprising a frame, a free traction-roller having two di ameters, the small diameter having its face engaged with the main cable and the large 'diameter lying at one side of the main cable and having` the haul-rope engaged therewith, and sheaves engaged with the haul-rope at opposite sides` of the vertical center of the traction-roller,whereby to bow the haul-ro e yieldingly around the same and .yielding y press the traction-roller against the main cable.

3. A rope-carrier for conve Yer systems comprisinga body, a duplex (riving-roller having a large and a small diameter arranged side vby Side, the small diameter being adapt ed to engage the eonveyer-traekway or main cable and the large diameter being adapted to engage the conveyer haul-ro e and said drivingroller being freely mova )le with rv spect to the carrienbody transversely of said cables toward and from the same, and means for exin the haul-rope against the said driving-ro ler.

4. In a eonveyer, a rope-carrier comprising a frame, a free traction-roller having two pes ripheral grooves arran ed side by side, one adapted to enga e wit the conveyor main eabie, and the ot er adapted toengagewith the conveyer haul-rope, and means adapted to engage the said haul-rope at opposite sides of the vertical center of the tractionroller whereby to bow the haul-rope slightly around the traction-roller and yieldingly press the roller against the main cable.

5.. In a eonveyer a rope-carrier comprising airame, a free traction-roller having two peripheral grooves arranged side by side, one groove engaged with the main Cable and the other groove lying at one side of the main cable engaged with the haul-rope, and sheaves engaged with the haul-rope at opposite sides of lhe vertical center of the axis of the traction-roller, whereby to bow the haulrope yieldingly around the same and yieldingly press the traction-roller against the main eable.

(i. A rope-Carrier for Conveyer systems coinl'irising a body, a duplex driving-roller having two peripheral grooves arranged sidi` by side, one ada ted to engage with the eonvcyer main cab e and the other adanted to engage with the eonveyer haul-rope said driving-roller beingr freely movable with r0- spect to the carrier-body transversely ol` said cables toward and from the same, and means for fiexing the haul-rope against the said driving-roller.
