COAL-ELEVATO R.

SPECIFICATION forming part. of Letters Patent No. 305,78%, dated September 30, 1884:.

Application filed February 6. H84. (No model.)

from bins or other places of deposit, and discharging it into cars, lighters, or other vesicls.

The invention consists of a portable elevator having two parallel sets of buckets for vertical lifting, between. the lower extremities of which is fixed adouble mold-board for turn ing or directing the coal equally to each set of buckets as the device advances into acoal pile and it consists, further, of an adjustable elevatorleg arranged at an angle in front of the vertical sets of buckets, and designed for breaking down the coal to within reach of the vertical elevators, or to elevate the coal and discharge it into sa-idelevators; and it consists, further, of a scoop or guard fixed on the timbers of the device and extending forward beneath the vertical elevator-buckets, for the purpose of preventing any of the coal in the pile operated upon from falling or sliding rearward of the vertical buckets, and for the purpose of affording a receptacle from which said buckets may conveniently raise the coal; and it consists, further, of certain novel devices for transmitting power to the elevator mechanism, and devices for directing the discharge of the coal-elevator, all of which will be hereinafter set forth.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figures 1 and 1. (illustrated on two sheets) is a side elevation of my improved elevator. Fig. 2 is an end elevation of that portion of the device designed for directing the discharge of coal. Fig. 3 is afront elevation with parts broken away to exhibit other parts. Fig. lis a rear elevation of the same with parts broken away to exhibit other parts. Fig. 5is a rednced plan of the elevator. Fig. 6 is a sec tional plan on one side of a central longitudi nal line on line ac m, Fig. 1. Fig. '7 is a see tional side elevation of a portion of the device.- Fig. 8 is a partly-sectional elevation of certain details of the device.

The elevator-platform A is supported at its front end by two traction-wheels, A',iixed on an axle, A, and at its rear end by a steering-wheel, A, the vertical shaft A of which passes up through the platform A, and is provided with a handle or tiller, A, that is designed to be within easy reach of the operator, that he may thereby guide and direct the elevator at w1ll. Vertical frames B B, suitably secured to the prolonged side timbers of the frame or platform A, and braced by braces to (a, support on shafts B B respectively, four sets or pairs of spiders, B B*, over which are stretched belts or chains B to which are attached in the usual manner the elevating buckets a a. Preferably hoods B are secured to the frames B B over the tops of the vertical elevating devices, as shown.

Secured on the platform A are a boiler, O,

furnished with smoke-stack C, and on either side thereof engine-cylinders from which power for operating the device is transmitted through piston-rods b and pitmen b to eccentries O that are secured on opposite ends of a transverse shaft, 0, which is suitably journaled in the sides of the frame A. On this same engine-shaft G is rigidlyfixed a worm, G, that gears with acog-wheel,D,which is secured on the counter'shaft D, that is j ourualcd to suitable standards supported on the frame A. This shaft D, extending across from the shaft C to the shaft A", has on its other end a worm, D thatis designed to engage with a cog-wheel, A, on said shaft A, so that the motion of the shaft G shall be transmitted to the shaft or axle A The cog-wheel A is loose on its shaft, and is designed to be made tight by means of a clutch, d, on said axle A", whereby when.

power is applied to the device the axle A may be rotated and the machine be propelled, and when the clutch d is withdrawn the wheel A remains loose on its shaft and the propulsion of the machine ceases. Fixed also on the shaft O is a loose sprocket-wheel or peripherallygrooved pulley, O, that may be made tight by the engagement with it of the clutch d, and power is transmitted from this wheel G by an endless chain, f, to the wheel E on the shaft E, which latter, journaled in the frames a shaft, I, on which is B B, is thereby made to revolve and transmit power for moving the vertical elevator-buckets by means of pulley E, fixed on shaft E, and chain E to the pulley F, k eyed on the shaft B.

On each end of the shaft B is also secured a peripherally-grooved pulley or sprocketwheel, B B, from which power and motion are transmitted by chains B to the wheels G on the shaft G at the lower end of the adj ustable elevator-leg G. 011 the same shaft, G", are wheels G, and at the upper end of this elevator-leg are wheels G, fixed on a shaft, G, which is journaled in the frame-timbers of said leg. A wide belt, G, carrying buckets or shovels y, is stretched over these wheels G G". This elevator-leg G is adjustably held in front of the vertical elevating portion of the device by means of arms G whose terminal eyes embrace the ends of the shafts B G*, respectively, and by ropes H H, that have ends engaged in hooks or staples g in the frame timbers of the said leg, and are carried upward over pulleys H, fixed on a shaft, H in the frame B, and then downward and secured to pulleys H", that are fixed on a shaft, H, also journaled in frame B. On one end of this shaft His also fixed a B 1 h cog-wheel, H, as shown.

e owt e shaft H and journaled in frame B is a pinion, I, which gears with the wheel H". A crank on the end of shaft I enables the operator to revolve the said shaft I and pinion 1, whereby the pulleys H are made to wind up the ropes H H, and thereby raise the elevator-leg G to any desired inclination. By this means said leg G may be brought to the position shown in dotted lines, Fig. 1, or be lowered to the position shown in full lines,

' as may be best adapted to the slope of the pile buckets, and, together with the scoop K,

of coal operated upon. A pawl, 72, is de signed to prevent, when desired, the reverse movement of the pinion I. The braces G are adapted to move in vertical planes, and may be held at any desired angle by pins 5/, passing through them and into the semicircular racks G, that are fixed on the timbers B. The double mold-board K is secured by bolts or other suitable devices between the inside front timbers of the frame B, and in front of the guard or scoop K, which latter is firmly secured to the rear timbers of the frame B by bolts Z, as shown, or, if desired, to the front of the frame or platform A. 'When the elevator is advanced against a pile of coal, the moldboard K operates to deflect the coal equally to either side to the upright e1evatoroperates to keep the track clear for the further advance of the elevator. The scoop or guard K is designed to have its front edge about on a level with the floor, so that no coal can work beneath it, and it also serves as a receptacle from which coal may be taken by the vertical elevator-buckets a. A guard, K of sheet metal, is secured to the side timbers and rear end of the platform A, and extends straight down at the sides to near the fioor on which the machine rests,while at the rear it projects in a triangular point, as shown, and at the front the said guard is designed to be fastened to the edges of the scoop K, the purpose being to prevent coal from getting beneath the elevator when it is at work, and interfering with its forward and backward movements.

'Coal elevated by the buckets a a falls intothe chutes L L and thence upon the endless belt L, provided with carrying-plates Z, which is partly inclosed in a horizontal conductor,

L open at top and bottom. This conductor L is partially supported by stringers Z, that form the lower edges of its sides, and are secured by bolts or otherwise to the frame B, and braced by braces Z that are also secured to said frame.

At each end of the conductor L is a shaft, Z Z, respectively, the one carrying two wheels, Z, and the other two wheels, Z, over which the belt L is stretched.

On the outer end of the shaft Z" is a wheel or pulley, Z, and a belt or chain, Z, connecting this pulley with the pulley B on the shaft B, transmits motion to the belt L.

From the stringers Z rise standards Z", that support shafts Z, carrying rollers Z", which hold up the belt L.

On the top of the boiler O is firmly secured a standard, M, having a tubular upward projection, m, in which is held the perpendicular leg of a T-shaped support, M. Set-screws m, entered through the sides of the tube m, and having their points engaged in the annular groove m of the support M, permit the latter to revolve,while preventingit from moving vertically. The head at of this support M serves as a support for the front end of an adjustable conductor, N, open at top and bot tom, which incloses a belt, N designed to receive coal falling from the belt L, said conductor being adapted to be adjusted in ahorizontal plane, for the purpose of delivering the coal to any desired point. Ajournal-box, m", secured on the bottom of the conductor N and embracing the head at" of the support M, holds the two together. The rear end of the c011- ductor L is supported on the front end of the conductor N, and near the rear end of the former, secured by transverse rods or bolts m, is a depending elevis or yoke, L, to which is connected, by a pivot, a, a yoke or clevis, N, turned in the contrary direction, and having suitably journaled in its depending ends a shaft, N, on which are secured a cog-wheel, N and two spiders orpulleys, N N for driv ing and supporting, respectively, the belt N of the conductor N.

Fitted over the tube m, on which they are designed to revolve, are a grooved pulley, M and a beveled cog wheel, M, respectively,

that are designed to be so connected with each' other as to move in unison in horizontal planes; and on an extremity of the head of the support M are fitted, so as to revolve together loosely thereon in vertical planes, abeveled cog-wheel, M, gearing with the wheel M and an ordinary cog-wheel, M, gearing with the wheel N. A chain, M, extending from the pulley 111* on the shaft E around the pulley M", consequently transmits motion to the belt N which is provided with suitable carryingplates, at.

In the rear end of the conductor N is journaled a transverse shaft, N, carrying two spiders,l\ N that, together with the above-mew tioned spiders N, support the belt N. This rear end of the conductor N is supported by a frame, 0, pivoted. by a pivot, p, so that it can turn thereon on a truck, 0. It will be seen,then,that, being supported at one end by the support M and at the other end by the pivoted frame 0 and truck 0, the conductor X may readily be swung laterally.

Across the bottom of the conductor N, near the rear end thereof, is secured a plate, 1,

down through the center of which hangs a post, P, that is retained in place by its head q resting on the plate q, and that serves as a pivot on which swings a discharge-chute, Q, that is designed to conduct to any desired point the coal falling from the belt N. This post 1? is held in place also by passing through the eye of brace 3, whose other ends are rigidly secured to the conductor N, as shown; and the chute Q is held in position by braces 'v v,seeured thereto, and having their eyes encircling the post P, and further support for the said chute Q is furnished by collars a? 00, one of which is fitted on the post I beneath the eye of the brace o, while the other encir eles said post beneath the eye of the brace 3. Because of this construction and arrangement the chute Q can be swung laterally, as indi cated'in dotted lines, Fig. 2.

I am aware that in many of its features this coal-elevator is not new, and hence strictly confine myself in my claims to such features as are novel and that experience has proven to be of great practical value.

I am also aware that grain-elevators have been designed with a swinging leg adapted to be lowered into the hold of a vessel, so that it can remove grain from a point below the body of the elevator; but I do not claim such a de vice.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A coal elevator constructed substantially as herein shown and described, embrac ing the following elements: a boiler and engine for operating the device, two parallel vertical sets of belts and buckets, a double mold-board, an adjustable elevator-leg,a scoop or guard extending forward beneath the vertical belts and buckets, a side and rear platformguard, worms and gear for transmitting power to the driving-wheel axle, and an adjustable horizontal conductor, and a chute adapted to be swung laterally, all arranged and operating as set forth.
