ALBIN E. SHODIN,` OF SEATTLE, `WASHINGTON.`

CONVEYING APPARATUS.

To all whom t may concern:

Be it known that I, ALBIN E. SHODIN, a citizen ,ofi the United States, residing at Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Conveying Apparatus, of which the following is a specification. l

`This in ing apparatus, and more especially to carriers which are employed upon a cable Way for the purpose of supporting the ropes leading to and from a load carriage.

The object of my invention is the provision yof a rope-carrier which will be of inexpensive and durable construction and provided with devices for propelling` the Same at a speed having a definite ratio to the speed of the associated load carriage.

With these ends in View, the invention consists in the novel construction, arrangement and combination of parts as will be hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a side elevational view of an elevated conveying system with devices embodying my invention applied thereto. Fig. 2 is a longitudinal vertical section of a rope-carrier, said section being taken through 2-2 of Fig. 4. Fig. 3 is a view partly in side elevation and partly in section, the section being taken substantially through 3-3 of Fig. 4. Flg. 4 is a section through 4 4 of Fig. 3.

Referring to Fig. l, the numeral 5 represents a track cable which, in the illustrated example, is supported by head and tail masts 6 and 7. Mounted upon said track eable'is a load-carriage 8 and wheeled rope carriers 9.

Connected to opposite ends of the carriage 8V are the ends 10 of a traction rope having hauling and return leads 11 and 111 respectively, which are guided by pulleys 12 to a drum 13 about which the traction rope is Wound as usual. 14 represents a hoisting fall extending from a winding drum 15 over a pulley 16 on the head mast 6, thence over spaced guide pulleys 17 1n the load carriage to have its end 141 secured to the tail mast 7. The hoisting fall between the pulleys 17 extends downwardly in the form of a bight which carries the fall block 18 to which loads are attached.

Referring now to Figs. 2, 3 and 4, a carrier is formed of a frame having two side plates 19 and 20, in the upper portions Specification of Letters Patent.

The sheave 23 serves as a support for the re-` spective hauling rope lead 11, the same be ing wound as at 111, Figs. 2 and 4 about the sheave one or more times to afford sufficient frictional engagement therewith to effect the rotation of the latter for propelling the carrier, when such hauling line is actuated, by employing the wheel 211 as a traction wheel upon the cable 5. For which purpose the shaft 231 and axle 21 are operatively connected by means of a train of spur gears consisting, as shown in Figs. 3 and 4, of a pinion 24 and a gear 25 respectively secured upon the shaft 231 and axle 21, and an intermediate gear 26 rotatable upon a stub shaft 261. The ratio between the teeth of the pinion 24 and the gear 25 is proportional to the speed at which a carrier 9 is intended to travel with'respect to the load carriage to maintain the former at a distance from the carriage to suitably support the aforesaid rope and fall.

1n the illustrated example (Fig. 1) where but two carriers are utilized, each carrier should operate at approximately midway be tween the load-carriage and the adjacent mast, thereby requiring the driven gear to be of twice the pitch diameter of the pinion. 27 represents a grooved sheave located, preferably7 at the rear of the carrier frame for supporting the return lead 111 when the latter is slack. 28 represents a sheave rotatably mounted in the lower part of the frame for supporting the fall rope 14.

The train of gearing for a carrier is desirably inclosed in a casing 29 to protect the same from injury and to exclude dirt. 30 represents a roller disposed within the frame below the wheel 221 and subjacent to the cable 5 for the purpose of preventing the adjacent end of the frame being tilted up when the carrier is being propelled in the direction of the arrow in Fig. 2.

The construction and operation of the invention will, it is thought, be understood from the foregoing description.

What I claim, is-

1. In apparatus of the class described, the combination with a track cable, a load mounted for travel upony said track cable, a pulley provided in the carrier for supportingsaid fall, a sheave provided insaid ear# rier and about which said hauling rope is Wound gear connections between said sheave;

and the Wheel for driving the latter to propel the carrier When the sheave is turned through the instrumentality of said rope.

2. In apparatus of the class described Y having a track cable, a load-carriage thereon, a hauling-rope for said carriage, and a fall extending to the carriage, VofV a fallcarrier comprising a frame having twoV Wheels mounted on said cable, a grooved sheave vprovided the frame andkabout Which saidhauling-rope is Wound to ai'ord frietional engagement for effecting the rotation of said sheave when the rope is actu- -fated tov haul the load-carriage, and gear connections between said sheave and one of saidy Wheelsto propel the carrier ,ata speed less than, that imparted to the Yloadearriage through thenedium of said rope.
