DISCHARGE APPARATUS FOR PIVOTED SPOUTS.

SPECIFICATION forming part of Letters Patent No. 570,055, dated October 27, 1896.

Application filed July 10,1896. $erial No. 598,670. (No model.)

To all whom it may concern.-

Be it known'that I, EDWARD F. REYNOLDS, a citizen of the United States, and a resident of Ashland, in the county of Ashland and State of lVisconsin, have invented certain new and useful Improvements in Discharge Apparatus for Pivoted Spouts; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to certain improvements in the class of apparatus such as is used especially on docks for the transfer to vessels of ore and coal, though not restricted to such use; and it consists in certain peculiarities of construction and combination of parts, as will be fully set forth hereinafter, and subsequently claimed.

In the drawings, Figure 1 is a side elevation, partly broken away, of a structure embodying my invention. Fig. 2 is a front elevation of the same with the spout or chute in a horizontal position. Fig. 3 is a detail View, partly in section, on the line 3 3 of Fig. 1. Figs. 4 and 5 are detail sectional views on the lines 4 4L and 5 5, respectively, of Fig. '2. Fig. 6 is a detail sectional view on the line 6 6 of Fig. Al.

Referring to the drawings, A represents a bin or dock-pocket, of ordinary construction, to hold ore, coal, or other material, supported in the usual manner upon or above a dock. B B are the side timbers of a frame (usually called a gallows frame) secured to the front vertical timbers b b of the bin or pocket A.

O is the spout or chute, whose lower end is pivotally secured to ears a a, projecting from said timbers b b.

D D are the spout-operating cables, whose ends are secured to the upper projecting ends of a yokeor strap 0, near the outer end of the spout O.

E E are free-running grooved guide-pulleys, secured to the outer ends of a shaft or axle d, which passes transversely through the side timbers B of the gallows-frame. F F are other free-running grooved guide-pulleys, mounted in brackets e e, secured to the lower front transverse timber f of the, bin or pocket A.

G is a front cross-piece rigidly secured to the central front support g of the bin or pocket A, and H is a rear cross-piece rigidly secured to the central rear support 7L of said bin or pocket. Brackets 'i 'i, carrying free-running guide-pulleys I I, are secured to the crosspiece G adjacent to its ends, and headed bolts J J extend through said cross-piece G and the vertical arms of the brackets i i, the heads of said bolts on the inner side of the crosspiece G being each provided with two eyes j is, one above the other. Eyebolts K K extend through the rear cross-piece H, near each end thereof, the eyes being on the inner ends of said bolts and their outer ends being screwthreaded to receive handled adjusting-nuts m m to regulate the tension of suspensioncables M M, which extend between and are fastened to the eyes of the bolts K K and the lower eyes 7c of the bolts J J.

L L are counterweights, from which rise angular straps n 02, between which straps are pivoted grooved pulleys N and O. The pulleys N are just above the tops of the counter- Weights L and are adapted to receive and run upon the suspension-cables M, While the pulleys O are between the extreme upper and forwardly-bent ends of the straps n n and are for the reception of the spout-operating cables D, which are arranged as follows: There are two of these cables and the upper end of each is secured, as stated, to the opposite ends of the yoke or strap 0, near the outer end of the spout or chute C. From thence the said cables pass upward over and around the pulleys E E, and thence downward beneath the pulleys F Fand back, beneath the bin or pocket A, to and around the pulleys O O on the counterweights L L, and thence forward to the upper eyes jj of the bolts J J on the cross-piece G, and there these ends are secured.

P P represent the drums of a winch p, j ournaled in the side pieces B B of the gallowsframe, which winch is provided with a friction-brake q and ratchet-wheel r, the latter controlled byadog or pawl s. Hinge-clutches Q Q are secured to the side pieces of the gallows-frame to control the cables D D, which pass through them, said clutches having each a screw-nut with handle, whereby the cable can be readily clamped at any time, as best shown in Fig. 6. R R are small chains connected to the drums P P of the winch, and secured to the lower ends of these chains are light cables S S, which pass down in front of the structure and under pulleys II and thence back to the counterweights L L, to which they are fastened, as shown at t t in Figs. 1 and 2.

The operation of my device will be readily understood from the foregoing description of its construction, taken in connection with the accompanying drawings.

The normal position of the parts is shown in Fig. 1 with the spout or chute G raised. Now by turning the crank of the winch p the small chains R It are wound up on the drn ms P P, and this action draws up the light cables S S and causes the counterweight-s L L, to which said cables S S are attached, to travel forward and upward on the inclined suspension-cables M M, and thus as the loop in the cables D D, which is around the pulleys O 0, carried by said counterweights, moves forward and upward the outer end of the spout or chute C will automatically move forward and downward byits own weight as fast as the forward movement of the said counterweights L L will permit, and said counterweights as they rise upward will serve to equalize the increasing weight and pressure of the clownward-descending spout or chute. \Vhen the spout or chute is down to the required point, (indicated by the dotted lines in Fig. 1,) the ratchet-dog .5- will hold it in position, while the hinge-clutches Q Q are adjusted tightly on the cables to hold the spout or chute rigidly in position.

In order to restore the spout or chute to its original position, it is only necessary to release the clutches and throw off the ratchetdog, when the reverse movement of the counterweights L L down the inclined suspensioncables M M will automatically raise the spout or chute. 13y the inclined arrangement of the suspension-cables M and the travel of the counterweights L thereon in either direction the uneven strain of the spout or chute occasioned by the different angles it assumes in its descent and ascent is always equalized and the unequal resistance overcome.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a discharge apparatus for pivoted spouts, the combination with a suitable support, of an inclined suspension-cable, a counterweight adapted to travel thereon, an additional free-running guide-pulley mounted on said counterweight, a series of free-running guide-pulleys mounted on said support at the front thereof, a spout pivoted to said support, and a cable secured to the outer end of said spout, and passing around said series of pulleys, and around the additional pulley on the counterweight, and thence brought forward and secured to the support at the front thereof, in line with the said series of pulleys, whereby the spout will be automatically raised by the downward travel of the counterweight 011 the inclined suspension-cable.

2. In a discharge apparatus for pivoted spouts, the combination with a suitable support, of inclined suspension-cables, counterweights adapted to travel thereon an extra guidepulley on each counterweight, a spout pivoted to said support, free-running guidepulleys on the support, cables connected to the outer end of the spout and to the support beneath the pivotal point of the spout, and passing around the free-running guide-pulleys on the support and counterweights, a winch on the support, and chain or cable connection between the drums of said winch and the traveling counterweights, whereby the winding of the chain or cable on the drums will draw the counterweights up the inclined plane of the suspension-cables, and permit the spout to automatically move forward and downward by gravity, as the said counterweights ascend.

In a discharge apparatus for pivoted spouts, the combination with a suitable support and a spout pivoted thereto, of inclined suspension-cables, and double-acting traveling counterweights moving thereon, freerunning guide-pulleys mounted on the support and counter-weigh ts and cables connected at their forward ends to said spout and pass ing around said guide-pulleys, the other ends of said cables being secured to said support.

In testimony that I claim the foregoing I have hereunto set my hand, at Ashland, in the county of Ashland and State of Wisconsin, in the presence of two witnesses.
