CONVEYING APPARATUS.

, SPECIFICATION forming partof Letters Patent N o. 577,192, dated February 16, 1897. Application led September l2, 1892. Serial No. 445,643. (No model.)

To a/ZZ whom it may conccrw Be it known that I, THOMAS SPENCER MIL- LER, of South Orange, in the State of N ewJ ersey, have invented a new and useful Improvement in Conveying Apparatus, of which the following is a speciiication.

One feature of my invention is a rope-carrier one member of which will be thrown into supporting position as the other member is thrown out of the carriage-pathway. Another feature is the mounting and actuating of the fall-rope, so that by separating or spreading its supports the fall-block is raised,

and in that position the carriage is caused to travel.

Other features are set forth in the claims. In the accompanying drawings, Figure lis a side elevation of one form of the apparatus containing my invention. Fig. 2 is a plan View of same. Fig. 3 is a side elevation of part of the carriage and one fall-rope support. Fig. 4 is a plan view of the same. Fig. 5 is an end elevation, partlyin section. Fig. G is a modification in detail.

ct and d' are hangers supporting the parallel trackways Z2 b.

c is a load-carriage composed of the two parts c c2, connected by the bars or other connections c3 c4. The part c' is provided with the four wheels d, and the part c2 (shown in in Fig. 5) with the four wheels e. The part c' is also provided with a sheave f, and the kpart o2 with the sheaves g and g.

7L is a traveler supported on the tracliways by the wheels z' and supporting the sheave j.

k is a sheave secured at the end of the trackways, and Z are guide-rolls mounted upon the outside of the hangers d.

m is a drum fixed upon a shaft m8 at the end of the space between the trackways.

n is a pulley mounted upon the same shaft with the drum m. The pulley is in three parts, the two outside parts a6 and n? being fast on the shaft ns and the central part n being loose on the shaft. The cross-belt n' and straight belt n connect the pulley n with a pulley '112, mounted on a driven line-shaft n4.

o is a drum which may be driven from the line-shaft n4 by the belt n3 through gears 'n10 nu. These cross and straight belts may be arranged to run side by side on the pulley n2, which is broad enough for that purpose, and

' carriage.

the pulley n, consisting of two fast parts sep arated by a loose part. By shifting the belts either the straight belt or the cross-belt may be made to drive.

' p is an outward-hauling rope extending from the drum 0 over the friction-rollers Z, around the sheave k, and back to the traveler 77 to which it is made fast.

q is an endless rope made fast at one end `to the carriage c and extending with one or more turns around the drum m, over fric` tion-rollers fr, around the sheave j, over the sheave g, down to a fall-block s, up again and' over a sheave g', over the sheave f, down to the fall-block s', and up again to the carriage c', where it is made fast.

tare the rope-carriers, one of which is shown in detail in Figs. 3 and 4. Each of them consists of a rocker t', pivoted at t2 to one of the tracks and carrying at opposite ends the ropesupports t3 t4, each containing a series of independent friction-rollers u. The rope-supports are so secured to the rocker t that when the rocker is in position shown in Fig. 4 the rollers carried by support t4 will be in the position shown in Fig. 4, where they occupy a' supporting position directly beneath the space between the trackways. At the same time the rope-support t3 will occupy the position shown in Fig. 4 at one side. lVhen the rocker t is rocked into its other position, the rollers carried by the rope-support t3 will be directly beneath the space between the trackways, and the support 4 will be at one side. Projecting from each of the rope-.supports t3 and t4 is a friction-roller '21, and hanging rigidly from the `block w3 of each carriage by side hangers @v2 is a delector w, inclined laterally at both ends, as shown in dotted lines, Fig. 4, in poi sition to strike against the roller o of either of the rope-supports t3 or t4 that happens to be in supporting position and push it to one side. The rocker t is long enough so that the distance between the rope-supports l153 and t4 is greater than the length of the carriage, so that as the forward end of the deilector on the carriage, moving in the direction of the arrow, Fig. 4, pushes rope-support t4 to one side the other rope-support t3 will swing into supporting position immediately behind the Therefore one or-the other of the rope-supports i3 or t4 must be in supporting position. The spring zo', operating in the two notches shown on the rocker t, will prevent the rocker from occupying any intermediate position. The inelines b2 serve toA center the rope onto the supporting-rollers u..

The operation is as follows: Suppose a load is being hoisted on each of the fall-blocks shown in Fig. l, that on the fall-block s being one ton and that on the fall-block s being two tons. The rope 29 is wound in upon the drum o. The first effect will be to haul out the traveler h, so as to haul the fall-block s up till it strikes the block w3 of carriage-section c2. The next effect will be to haul the fall-block s, carrying the heavier weight, up till it strikes the block zo* of carriage-section c. This is all caused by the movement of the traveler h in the direction of the arrow. rl`he drum o is now stopped and the drum m is started. Thus the traveler 71. remains stationary'and the rope q travels in either direction required, conveying the carriage o correspondingly along the trackway to the point required, whenthe drum m is stopped again and the rope p paid out until the loads are lowered. The rope-carriers t support the sag of rope q, particularly when the rope 1J is being paid out for the purpose of lowering the unloaded fall-blocks .s and s.

The sections contained in the carriage c, which I have shown as two, may be reduced to one or may be multiplied to any extent desired, in which lattercase the fall-rope will be correspondingly extended to each. In lieu of actuating the traveler 72.- by the drum 0 through the rope p it may be actuated by a rod h or other member, Fig. 6, connected with a piston h2, reciprocated within the cylinder h; by any power.

The function of the rocker t being to throw one of the rope-supports into position as thel other is thrown out, other members may be used as equivalents for the same purpose.

The supports t3 and t are shown as being carried by the rocker t', but they might be carried in guideways fixed to the track or otherwise supported.

I do not wish to confine myself to the double trackway shown and described.

1. In a conveying apparatus, in combination, a trackway, a load-carriage traveling thereon, a fall-rope hanging from said loadcarriage and extending horizontally to an end of the span, two fall-rope supports below the level of the horizontal portion of said fall-rope, means whereby the same are successively moved out of the way of the vertical part of said fall-rope and a connection between the two whereby the movement of one out of the way throws the other into supporting position below the horizontal portion of said fall-rope, substantially as described.
