COAL-HANDLING APPARATUS.

Specification of Letters I'atent.

Patented June 25, 1907.

.Application filed February 4. 1905. Serial No. 244,241.

To all whom, t may concern:

Be it known that I, WILLIAM F. KLEMP, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Coal- Handling Apparatus, of which the following is a specification.

This invention relates to apparatus for handling coal, coke, and other material, and is designed more especially for loading the tenders of locomotives in places where the ordinary 'coal chutes are not available.

The principal object of the invention is to provide for coaling the tender at a minimum of labor and expense by means of barrows or carts of large capacity which may be manip` uiated and dumped by a single workman, the construction of the barrow and the means for controlling its dumping movement being such that the forward end of the barrow may be tilted over an elevated platform to dis charge the coal into th'e tender without danger of dislodging the barrow from the platform.

A still further obj ect of the invention is to provide a loading and dumping mechanism wherein the coal or other material may be arranged in a wheeled receptacle of such nature tIiat the load will be in unstable equilibrium with the center of gravity in the vertical plane of the supporting wheels, and when dumped a new fulcrum point will be formed and the center of gravity disposed to one side of the new fulcrum point, so that there can be no danger of accidental overturning of the barrow.

A still further object of the invention is to provide in loading and unloading apparatus a barrow which when loaded will be in unstable equilibrium, and when tilted toward dumping position will move continuouslyT until it arrives at the full dumping position and will remain there until the load has been discharged, a new fulcrum point being formed for the load during the discharging operation, and the fulcrum again changing back to the axle of the carrying wheels after all of the contents of the barrow have been discharged, so that the barrow may be turned without difficulty to its ordinary horizontal position.

With these and other objects in view, as will more fully hereinafter appear, the invention consists in certain novel features of construction and arrangement of parts, hereinafter fully described, illustrated in the accompanying drawings, and particularly pointed out in the appended'claims, it being understood that various changes in the form, proportions, size and minor details of the structure may be made without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings z-Figure l is a side elevation of a loading and dumping apparatus constructed in accordance with the invention, showing the same as used for the purpose of coaling a locomotive. Fig. 2 is a rear elevation of a portion of the barrow. Fig. 3 is a longitudinal sectional elevation of the barrow, illustrating the dumping position in dotted lines.

Similar numerals of reference are employed to indicate corresponding parts throughout the several figures of the drawings.

In carrying out the present invention an elevated platform l() is arranged at 'a p oint convenient to the railway track, and at a suitable height above the top of the tender of a locomotive. Near one side or edge of the platform is a stop or fulcrum rail 1l which in the present instance is shown in the form of an ordinary railroad rail.

The stop or fulcrum rail must be correctly proportioned as to height and Width, as will more fully appear hereinafter. On the platform is a wheeled barrow 12, the body of which is preferably formed of sheet steel.

`The body ofthe barrow is supported on a transverse stationary axle 13, the ends of which are cranked or bent upward at the sides of the barrow and receive comparatively large supporting wheels 14. It will be noted that the longitudinal axes of the hubs of the wheels are in a plane somewhat above the bottom of the barrow, when the latter is in the horizontal position shown in full lines in Fig. 3. At the rear of the barrowis a pivoted caster 14 to permit the turning of the barrow in a small space, and the rear portion of said barrow is also provided with a handle l5 for convenience in moving the barrow from place to place.

The bottom of the barrow, from a point slightly forward of the axle to the rear wall 16 is horizontal, and its front end is arranged on a line oblique to the horizontal, as indi- IOO cated at 17, to thereby form an inclined discharge chute when the barrow assumes the dotted line position. The upper wall of the rear portion of the barrow is arranged on a horizontal line parallel with the line of the bottom, said horizontal portion of the top extending for a considerable distance to the front of the vertical plane in which the axes of the wheel hubs are disposed, and from thence is arranged at an incline to form side Walls for the delivery chute.

rl`he barrow in the present instance is designed to hold a ton of coal, and when fully loaded with the coal level at the top at all points, including the discharge nose or chute,

the weight will be distributed in such manner that the cubic content of that portion of the barrow to the rear of the vertical plane of the axes or fulcrum 2() Will be slightly less than half a ton, While the cubic content on the opposite side of such vertical line, or in front of the barrow, will be slightly greater than half a ton, the excess at the forward end being for the purpose of counter-balancing the superior weight of the rear end including the caster, its bracket, and the handle. l/Vhen fully loaded, therefore, the weight, including the barrow body, will be equally divided on opposite sides of the fulcrum 20, but the center of gravity of the load will be at a point somewhat above the fulcrum, and disposed at an angle of five degrees, more or less, to the rear of the vertical plane of the fulcrum: The load will therefore be in unstable equilibrium, and owing to the comparatively large diameter of the supporting wheel the loaded barrow may be readily moved to the dumping point by a single operator, it being found in actual practice that a single person mayhandle with ease a barrow containing a ton of coal.

The loaded barrow is wheeled directly against the dumping fulcrum l1, and the gparts are so proportioned that when in this position the outer edge of the upper surface of the fulcrum bar 11 and the fulcrum -20 will be in a common plane at an angle of forty-five degrees to the horizontal, or in other words, will form respectively ends of the hypotenuse of a right angle triangle` whose vertical and horizontal sides are of equal extent, the vertical side being in the vertical plane of the fulcrum 20, and the horizontal side in the horizontal plane of the fulcrum 1l.

When the barrow is wheeled against the dumping fulcrum the operator merely releases the handle and the acquired momentum of the barrow and load will shift the center of gravity to and beyond the vertical plane of the fulcrum 20. and, the load being in unstable equilibrium, the forward end of the barrow will move down in the arc of a circle struck from said fulcrum 20. This movement will continue until the inclined bottom portion of the barrow strikes the dumping fulcrum ll, and then if the wheels have not moved in close contact with the bar, or have slightly rebounded, the load at the outer side of the fnlcrum bar will draw the wheels forward until they engage the inner side of the fulcrum bar and the wheels and 'bottom of the barrow will thus become interlocked with the bar. At this time the fulcrum point shifts from 20 to the bar l1, but the greater volume still remains to the rear of the vertical plane of the ful'crum 11, while the load gradually iiows from the front of the barrow. It will be observed that in dum ing position the discharge chute formed by tllie bottom of the barrow is at an angle greater than the angle of iiow of the coal, so that the latter cannot adhere to the chute, but will flow freely until the full contents of the barrow are discharged.

With the empty barrow in the dotted line position shown in Fig. 3, or the full line position shown in Fig. l, the weight to the rear of the fulcrum l1 will be ap roximately twothirds that of the full weig t of the barrow, the remaining third being to the front of the fulcrum, so that there is no danger, whatever, of the accidental tipping over of the barrow, and it will at all times retain its position on the platform.

During the discharge of the load it is not necessary for the operator to hold the barrow in place, it being found that when moved to dumping position by its own momentum, or by a slight upward push on the part of the operator, it will remain in the dumping position until fully emptied. The operator then pulls downward on the handle, the fulcrum 20 now coming into play, and the barrow being restored to its horizontal position wi th but slight effort.

It is of course obvious that the barrows may be made of any size in order to dump larger or smaller quantities of coal, or other material, mention of single ton barrows being made for the reason that such barrows have been found in actual practice to effectually accomplish the work.

Having thus described the invention, what is claimed is v A hand barrow having fixed handles projecting rearward from the body portion thereof, supporting wheels, a cranked axle disposed rearward of the center of thelength of the barrow body and near the bottom thereof, the upper edges of the sides and the bottom of the forward portion of the body being inclined upward and of much greater length than the rear portion of the body to permit descent of the discharge end of the chute much below the bottoms of the wheels when dumping, the two portions of the body on opposite sides of the vertical plane of the axle being of approximately equal weight, and cubic content, whereby the load is main- IOO IIO
