CONVEYING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 555,080, dated February 25, 1896.

Application filed May 31,1895. Serial No. 551,079. (No model.)

I all whmn it may concern:

Be it known that I, J AMES G. DELAXEY, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Conveying Apparatus, of which the following is a specification.

Heretofore various attempts have been made to produce a practical apparatus for an aerial dump in hoisting or conveying.

One objectof the present invention is to enable the result of dumping in mid-air with certainty and without liability to accident, and by means of an apparatus simple and economical in construction, and, if need be, adjustable to various heights, as may be required. This consists in connecting with the fall-rope a contacting device and providing mechanism adapted to be started and, preferably, also engaged by said device, which mechanism is normally inactive but which is so connected with the load as to dump the same when actuated.

In the accompanying drawings I have represented sufficient of a hoisting and conveying apparatus to illustrate my invention when applied to a cableway; but it will be understood that I do not limit myself to that form of hoisting or conveying apparatus, but intend to cover the invention broadly as applied to any form of hoisting or conveying apparatus.

In the drawings, Figure 1 is a side view of the load-carriage and adjacent parts with the skip or bucket in its normal carrying or hoisting position. Fig. 2 is a side view of the same in a dumping position. Fig. 3 represents, enlarged, one form of contacting and engaging device that maybe used connected with the fall-rope. Fig. 4. represents another form of the same that may be used. Fig. 5 is a detail showing a top view of a portion of the fall-block and of the contacting device 7b, which is connected with the dumping mechanism, and one form of projection for centering said device h. Fig. 6 is a modification of the same. Fig. 7 is a sectional detail of another modification of the same.

It will be understood that the form of apparatus shown in the drawings is merely introduced by way of illustrating and admits of indefinite variation without departing from the full scope of my invention, since I believe that I am the first to connect a contacting device with a fall-rope of a hoisting or conveying apparatus for the starting or actuation of mechanism; but within this broad invention there are features of invention which I also desire to secure.

a is the cable or trackway. The load-earriage consists of a framework Z), upon which are mounted the wheels Z) Z) and the fall-rope sheaves 5 Z) and the guiding-sheave b for the endless traction-rope.

c and c are respectively the connections with the carriage of the endless traction-rope that is generally used for causing the loadcarriage to travel across the span.

0 is the other portion of said endless traction-rope.

(Z is the fall-rope, which will be operated by any suitable motive power and which may support the fall-block e by any desired number of rope parts for instance, as the three parts (1', (Z and (P.

e is the fall-block sheave, and e is the hook by which the tall-block is engaged with the load-suspenders, of which there are generally three, one, as f, supporting the rear of the load, and two, as f, supporting the front of the load on each side. To include all other forms of mechanism, as well as that shown, for suspending the load from the fall-block when the dumping is not in operation, I will refer to it as mechanism whereby the load is normally suspended from the fall-block. These suspenders may be connected with the load in any suitable manner, but are shown in the drawings as being connected with the load by being connected with the skip or bucket g containing the load.

The parts so far pointed out maybe of any ordinary construction.

h is the preferred form of what I call the dumping mechanism, and, in the form shown, it consists of a suspender which is practically inactive until the dumping takes place, when it operates to take the support of a portion of the load away from the suspender f, and thus produce a diiferential motion between the supports at two parts, as 2' i, of the load, causing the tipping of the load.

To include all other structures and mechanism that may be substituted for the suspender h to connect the fall-rope with one side of the load, so as to produce the differential motion referred to, I will use the term dumping mechanism.

The dumping mechanism is brought into action by a contacting device connected with the fall-rope, the form and number of parts of which may be varied almost indefinitely, but which, in the simplest form at present in use, is shown in the accompanying drawings, and consists of an enlargement or shoulder j, preferably produced by a spreader j, Fig. 3, inserted between the strands of the fall-rope. It may, however, otherwise consist of a link or cross projection, as k, Fig. 1, introduced in the fall-rope. The enlargement j or the projection 7t, as the case may he, acts as the contacting device to start and engage with the dumping mechanism h. For this purpose the dumping mechanism his provided with a contacting device to co-operate with the contacting device j or 7e on the fall-rope, and it may be in the form of a ring h, through which the fall-rope passes freely in hoisting the load until the contacting device on the fall-rope comes along. Thereupon the contacting device on the fall-rope will start and engage with the contacting device on the dumping mechanism and start and actuate the dumping mechanism so as to produce the dump. In the form shown this actuating consists in lifting the dumping mechanism h from the position shown in Fig. 1 to the position shown in Fig. 2, so that the part c" of the load is lifted faster than the part i of the load. This produces the differential motion above referred to.

To include all forms of mechanism that may be used in place of the enlargement j and ring or eye It for coming into contact with each other, so as to determine when any mechanism connected with ring h is brought into action, I use the term contacting devices, and to designate contacting devices so constructed that, after contacting, one carries the other along with it, I use the term engaging devices. In this form, when the dumping mechanism is not in operation, it y will be supported by the fall-block in position ready to be struck and carried along by the contacting device of the fall-rope when the latter comes along.

lVhen the form of contacting device on the dumping mechanism is like that shown in the drawings, it is desirable that it be held normally out of contact with the fall-rope, so as to prevent the chafing of the latter, and for this purpose I have used a projection or projections Z Z bolted to the side pieces 6 e of the fall -block and projecting upward, as shown in Figs. 1, 2, and 5, so as to substantially center the device it around the fallrope. This centering function, however, might be performed by projections Z Z Fig. 6, on either side of the link It or by a funnelshaped inclosure 1*, Fig. 7.

In the form shown the device j or k con nected with the fall-rope performs a dual function. As the first function, it determines the time or position of the hoist at which the dump shall take place by starting or tripping the dumping member into operation, and as the second function it provides the power by which the dump is effected or by which one part of the load is supported while the dump is taking place; but I do not desire to limit myself to a mechanism in which the engaging device on the fall-rope performs both of these functions, since I believe it is new to provide a contacting or engaging device connected with the fall-rope performing either of them.

As shown in Fig. 1, the contacting device j will normally be on the rope parts d d between the fall-block and the made-fast end 61 of the fall-rope, so that before it contacts with h it must pass around the fall-block sheave. For this reason the space between the groove of the fall-block sheave e and the frame of the fall-block should be large enough to admit of the passage of the device j, and the projections Z Z should be capable of being sprung apart as the device j passes. As the device passes, they should spring back again, so as to be the proper distance apart for centering 71, as shown in Fig. 5. The device j or it is made with deflecting surfaces at each end, so as not to engage with any part excepting the device h.

By varying the location of the contacting device 9' or 7t on the fall-rope the elevation at which the dump will occur can be varied indefinitely.

I am aware that in patent to Miller, No. 525,084, dated August 28, 1891, is shown the combination of a fall-rope, a fall-block mechanism whereby the load is normally suspended from the fallblock, a dumping mechanism connected with the load, and contacting devices, and I make no claim for the same; but said contacting devices are in said patent connected respectively with said dumping mechanism and the load-carriage, and not, as in this application, respectively with the (lumping mechanism and the fall-rope.
