COAL-ELEVATlNi G APPARATUS SPECIFICATION forming part of Letters Patent No. 542,558, dated July 9, I895.

, Application filed January 14, 1895, Serial No. 534,852. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE HAISS, of New York city, in the county and State of New York, have invented a new and Improved Coal-Elevating Apparatus, of which the following is a full, clear, and exact description.

This invention relates to an improved apparatus for the elevation of coal or other lumpy or granular material from alower toa higher plane, and particularly to such devices for the designated purpose as are used to raise coal from boats along a wharf or'the bank of a river or other water-course, and discharge the coal as elevated into a car or other receptacle. Ordinarily a jib-beam is rigged to swing from a fixed support at a suitable elevation, so that it may be projected over a boat and afford support for blocks and falls that are utilized for the elevation of a coal-scoop which has been lowered into the boat and filled with coal.

The operation of handling coal by the use of the ordinary device that has been explained is slow and tedious, and as the jib must for security and its free operation be fixed in.

about a horizontal position it is liable to interfere with the subsequent movement ofsailingc raft along the wharf, unless the jib-beam structure at a wharf or other point convenient thereto, so that the vessel from which coal is to be removed by means of the improved mechanism can be located near the wharf.

A further object is to provide an adjustable support for an automaticallyfilling coalshovel, which support is adapted for convenit ient and safe actuation and control by steam To these ends the invention consists in the construction and combination of parts, as is hereinafter described, and indicated in the claims.

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

Figure 1 is a side elevation of the improved hoisting apparatus, portions of the supporting-frame being removed. Fig. 2 is an enlarged plan view of details of construction, comprising a movable truck and a portion of the trackway that supports said truck, seen in direction of the arrow 2 in Fig. 1. Fig. 3 is a front view of the elevating apparatus, the lower portion of the frame being removed and the elevator-shovel also removed to render other. parts more distinct; and Fig. 4c is an enlarged transverse sectional view on the line 4 4 in Fig. 1.

In carrying the invention into effect an upright frame structure or derrick 10 is provided, which is made of any suitable material and afforded a sufficient height for the proper operation of other parts that constitute the main features of the invention. A portion of the framework 10 may be that of an inclosed building and have a roof provided for the protection of working mechanism that is supported on the frame below the roof, as indicated by dotted lines in Fig. 3. The structure or derrick-frame 10 is erected at a point close to the water if the apparatus is to be used for the removal of coal from a boat, and

bolts 'll, which hold the channel-beams in a.

correctly-spaced condition, so that a small truck 12 may be introduced between the beams 11 and loosely engage its wheels with .the flanges of said channel-beams. The beams 11 are slightly curved edgewise near the end of the trackway which is innermost in service and the beams are pivotally supported at a point near the inner extremity of the same.

Preferably the trackway is supported free to receive adjustment by pivot-trunnions 11,

which are sustained by brackets .on two aligned cross-beams 10, which are braced by other parts of the frame 10, so as to be adapted for the reliable support of the trackway and any load it may be required to bear. The two beams 1O are so separated at their inner ends that the trackway may be rocked be-' tween said ends; but this may be readily changed by providing higher brackets for the trunnions, so that a continuous cross-beam may be employed in place of the pair of aligned and separated beams.

The convex curved edge portions of the beams 11 are uppermost in use, and for efficient operation means are required to allow of the inclination and reliable support of the trackway at an angle from a vertical plane that will best suit the requirements of its service as a support for the elevating device proper.

While. various means may be utilized for the adjustable inclination of the trackwaybeams 11 on their pivot-supports, for convenience and reliability the appliance shown is preferred, which consists of the following-described parts: A winch 13 of any approved construction is secured on the frame 10,having its drum 13 supported on a transverse shaft 14, journaled in boxes at each side of the frame 10, and on the drum-shaft, near its opposite end, another drum 14 is secured, as shown in Fig. 3. other suitable flexible connections, are provided, said ropes being attached at one end to the winch-drums 13 14?, their opposite extremities being secured to the outer end of the trackway-beams 11 or to lateral projections therefrom, the ropes receiving support intermediately of their ends upon the pulleys 16, mounted on the frame 10, near each side of the same, as shown in Fig. 3.

It will be evident that a rotation of the winch-drums by-aproper manipulation of the winch will cause a movement of the trackwaybeams ll to elevate their outer ends, an opposite movement permitting the gravity of the projecting trackway portion to depress said trackway and cause it to assume a normal position.

A transverse beam 10 is so located on the frame 10 that it will receive the impinge of the inner end of the trackway when the latter has been given a correct inclination for service, and will afford a stable support for said end of the trackway, and if the ropes 15 are drawn taut and so retained by the usual ratchet-and-pawl device of the winch the trackway will be reliably secured in a desired position for use.

As a further means for the support of the trackway, so as to prevent a lateral swaying movement of its outer end when adjusted as has been explained, two guy ropes or chains 17 are extended downward and laterally from its outer end or from lateral projections on said end having their opposite extremities fastened to the sides of the frame 10 or to other Two wire ropes 15, or

The small truck 12, which is designed to travel in or on the trackway-beams 11, is provided with four wheels of an equal diameter, and they are so sized that they will roll on the lower flanges of the beams and nearly touch the upper flanges of the same, the lastmentioned flanges serving to prevent an upward displacement of the truck when in service.

Between thepairs of wheels on the truckframe which travel on the trackway-beams two grooved pulleys 12 are mounted intermediately of the sides of the truck-frame, as clearly shown in Figs. 2 and t, and on these pulleys two similar hoisting-ropes 18, preferably formed of wire strands, are imposed. The ropes 18 pass down through the frame of the truck 12, and have their depending ends secured to'the elevating-shovel 19, and the latter is preferably of a type which is adapted to scoop itself full when two sections of the same are actuated by draft-strain applied to the ropes 18.

Two similarlygrooved pulleys 20 are mounted on the upper part of the derrickframe 10, substantially in the same vertical v plane with the'grooved pulleys 12 on the truck, and the hoisting-ropes 18 are extended from the latter over the pulleys 20, from which they trend downward to have their other ends attached to a power-driven drum 2l, that is rotatably supported on the frame 10, so as to lie crosswise on the latter.

The drum 21 is shown as adapted for rotation by a belt 21, that may be extended to any suitable source of power and rotary motion; but it is not essential how the drum is actuated for its rotation, as a sprocket chain or shaft and miter-gearing of ordinary construction can be applied if preferred, or the drum may be directly connected to an electric motor and be revolved thereby.

At a suitable point on the frame 10, above the cross-beams which support the trackway and nearly opposite the upper extremity of the latter, an elongated pulley 22 is journaled in proper supports, which pulley is transversely placed on the main frame, as shown l. The rope 23 is arranged to occupy one end portion. of the pulley 22 1 when itis wrapped on it, as shown in Fig. 3, and it will be so Wrapped when the truck 12is at the .lower end of the trackway. On the opposite end of thepulley 22 a take-up rope 2% is secured by oneend.

The take-up rope 24 is wrapped on the pulley 22, so that its free end will hang pendent on the rear side of the pulley and be adapted to wrap upon the pulley as the draft-ropet23 is unwrapped therefrom, and to said free end of the rope 24 a weight 25 is suspended, which may hang free, as indicated in Fig. 3, or beloosely inclosed in an upright box, as

'shown inFig. 1.

is provided to stop the rotation of the pulley 22 when the truck hasarrived at the outer end of the boom and theshovel is being filled and raised, the device-of friction-band type, which isrepresented clearly in Fig. 1, being shown as one means for controlling the rotary movement of said pulley. The friction-band 28 is drawn upon the periphery of the pulley 22 by means of a pivoted lever 29 and cord 30 that extends down from said lever to another horizontal lever 31 conveniently located for manipulation by the operator or attendantof the elevating apparatus. it These devices constitute a locking mechanism whereby the truck is prevented from being moved up thtrackwayuhder the weightof theloaded shovel until said shovel has been lifted up sufficiently near the truck. This locking mechanism may be operated by means of the lever 31 on the supporting-frame at anydesired time.

In operation it will be seen that the weight of the truckand the degree of inclination given to the trackway-beams 11 when adjusted for service will cause the truck 12 and elevating-shovel 19 to descend the trackway and occupy the relative positions represented in Fig. 1, it being necessary that the drum 21 berotated so that the hoisting-ropes 18 may unwrap therefrom when the truck and shovel are to receive such an adjustment. A continuation of the reversed rotary movement of the drum 21 will allow the shovel 19 to descend and engage the material, such as coal, and when embedded in the mass of coala rotary movement of the drum 21 in direction of arrow 4 will wrapthe hoisting-ropes on said dru m, causing an elevation of the shovel.

After the filled shovel has been drawn near to the truck 12 the weight of the load, together with the draft-strain on the hoisting-ropes 18, will cause the truck and shovel to ascend the trackway and occupy its upper portion, the

curved endsof the trackway-beams so reducing the degree of inclination of the latter as to permit the truck and loaded shovel to remain in elevated adjustment, and to insure the truck against descent on the trackway untildesired a keeper-pin 32 is introduced into transversely-aligned perforations in the l sides of the truck-frame, as indicated in Fig. 1. The use of the keeper-pin 32 may be deemed unnecessary, as there is such a weight-pressure onthetruck, due to the suspension of the shovel from the hoisting-ropes, and while the truck and shovel are in elevated adjustment, asindicated by the bent dotted lines thatin part represent the ropes 8, the loaded shovel willremain stationary until its contents are dumped into the hopper 26 by any provision made to effectthe release of the closed sections of the shovel; and as this is not a part of the invention it is notconsidered necessary to more fully illustrate or describe the shovel.

The discharge of the contents of theshovel 19 may be produced either automatically when thetruck 12 is at or near the top of the trackway or may be manually effected by theoperator; and when theshovel is emptied a reverse movement of the drum 21 should be i produced which will allow the truck to descend the trackway for a repetition of the:

hoisting operation.

The weight 25 will have unwrapped a considerable portion of the rope 2 1 whenthetruck 12' is at the lower or outer end of the trackway, and the draft-rope is then correspondingly wrapped on the pulley 22. As soon as draft-strain is applied to thehoistingropes 18 the draft thus applied to the truck 12 will move it up the trackway and unwrap the rope 23 from the pulley 22, atthe same 1 time wrapping the rope 24 thereon.

It will be seen that the traverse of the truclc on the trackway will be rendered steady and under complete control by provision of the ropes 23 21, weight 25, and the friction-brake device, so that the descent of the truck and shovel can be regulated at the will of the from the Water-course or railroad-track, so

that vessels or cars can be moved with out any obstruction from the improved elevating apparatus when it is not in service.
