Specification of Letters Patent.

Patented Aug. 10, 1909.

Application filed June 29, 1908. Serial No. 439,633.

To all whom it may concern: I

Be itknown that 1, JOB E. JONES, a citizen sion of means for facilitating the loading of a box-car or like vehicle.

7 Another object of the invention is the cone struotion of a vertically-adjustable chute carrying a loader, which is adjustably mounted thereon.

A further object of the invention :is the provision of means for adjusting an auxiliary chute or a loader upon a primary chute,

and also the adjusting of the primary chute' relative to a receptacle or car which is'to be loaded.

With these and other objects in view, the

invention consists of certain novel constructions, combinations, and arrangements of parts, as will be hereinafter fully described and claimed.

In the drawings: Figure 1 is a view in side elevation of an apparatus constructed in accordance with the present invention. Fig. 2 is a top plan view of the apparatus de icted in Fig. 1. Fig. 3 is a vertical, sectiona view taken on line 3, 3, Fig. 2. Fig. 4 is a sectional view taken on line 4, 4, Fig. 1. Fig. 5 is an inverted plan view of the loader'or auxiliary chute. Fig. 6 is a fragmentary, sectional view of the loader or auxiliary chute. Fig. 7 is a detail view of the clevis connection between the toggle levers and their operating chain.

Referring to the drawings by numerals, 1 designates beams of a suitable framework upon which are mounted or secured rails 2; said rails are, preferably, tee-iron rails. Each rail is provided at its outer end with a hook or upwardly curved or bent portionS, for stopping the truck 4.

The truck 4 comprises flanged wheels 5 secured to or journaled upon shafts 6; the,

shaft 6 being attached to a framework 7,

which framework. is provided with short standards 8. The standards 8 are provided with brackets 9 in each two of which brackets, is j ournaled a transverse shaft 10. Upon eachshaft 10 is mounted a pulley or curved wheel 11. The wheels 11 extend transversely of the tracks for the purpose hereinafter described. The tracks are constituted by saidbeams or ties 1 and the rails 2.

The primary chute is provided with an upper, openend 13, Fig. 2, for receiving the coal from the mine chute above, which constitutes a single continuous chute from the tipple to the car. The primary chute 12 converges toward its lower end, as at 14, and terminates at its lower end in an outwardly flanged or flared portion 15; the extreme lower end 16 of the chute 12 is cut substantially V-shaped, the sides of the V-shaped structure being slightlyfcurved for conforming to the inclined'shape of the sides 17 of the bottom of the auxiliary chute or loader 18, hereinafter described. The upper end of the chute 12 is secured to a shaft 19, which shaft is provided with flanged wheels 20; said shaft constitutes an axle'forwheels 20. The wheels 20 travel upon the rail 2 and pivotally support the u per end of the chute upon the .bracket. hafts 6 and 19 are connected by a pair of horizontal bars 21, whereby, as the iupper orrear end of the chute 12 is adjusted upon the bracket or framework, the truck 4 will also be synchronously adjusted, thereby retaining the truck in a given position at all .times relative to the rear end of the primary ichute 12. Secured to the sides of the chute 12 are dependinglJ-shaped brackets 22. These brackets 22 are, preferably, formed of angle-iron andthe lower portion of each bracket constitutes a track upon which travels a flanged wheel 23. I

The wheels 23 are secured to or journaled upon a transverse shaft 24, which shaft 24 supports the inner-or upper end of the loader or auxiliary chute 18, as the loader is pivotally secured to said shaft by any suitable means.

' Carried by each track is a horizontal bar 25, which, preferably, engages the top of the wheel 23 for preventing accidental displacement of the wheel off of the track carrying the same, irrespective as to the adjustment or jarring of the loader or auxiliary chute 12. l tended to the farthest position, within the However,- it is to be noted that the loader or auxiliary chute 18 can be adjusted longitudinally of the track,- and, consequently, longitudinally of the primary chute 12, whereby the loader or auxiliary chute can be placed under the primary chute, as shown by dotted lines 26, when the operator desires.

The loader comprises a bottom, formed by the inclined sides or portions 17, each of which sides is connected at its outer edge with an angle-iron or member 27, Fig. 3,

each of which angle-irons is provided with an elongated slot or opening in its side, in which is slidably mounted a fiat wing or plate 28, the wing or plate 28 being of sufiicient width to extend under the lower end of the chute 12, Fig. 1. A pair of crossed levers 29 are pivotally connected near their center, as at 30, and each lever is provided near its outer end with an elongated slot 31, within which slot is mounted a' stud or lug 32 for connecting said lever to a wing. Toggle levers 33 are employed for operating the crossed levers 29, said toggle levers having one of their ends pivotally connected to said crossed levers 29, the other ends of the togglelevers being held in pivotal relation by means of a double clevis 35 preferably composed of a short length of chain one link of which forms the pivotal connection between the toggle levers. A chain 36 is coiled about the shaft 37 and has one end fastened to the free end of the double clevis 35*, the other end portion of said chain extending to and around the s rocket wheel 38, and thence to the pivot 'lin r of the double clevis. This arrangement of the chain 36 and its connection with the double clevis, permits of the toggle levers *being relatively expanded or contracted, according to the direction in which the pull is imparted upon said chain.

When the loader is being put into a car, the chain is placed in a slot or fork, whichis fastened or bolted to axle 23, Fig. 6. The loader is then pulled into the car or is with drawn, as desired, and then, the chain is dropped out of the fork or hook 40. Then, upon continuing turning the crank on shaft 37, in the same direction, this will result in extending the wings or plates 28. When pulling the loader back again, underneath the chute 12, by turning the crank in the opposite direction, the wings will be folded underneath the loader. After this is done, the loader can be ulled underneath the chute 12 by continuing to turn the crankshaft. Rotation of crank shaft 37, in one direction, results in the inner ends of the toggle bars 33 being spread apart, which also results in the spreading apart of the outer ends of the levers, and in the extending of the wings orplates, as shown in Fig. 2. Upon continuing rotating the shaft in one direction, after the wings have been exsides of the bottom or body of the loader, the loader will be projected beyond the discharge end of the chute 12. hen it is desired to draw the loader under the primary chute or longitudinal brackets 22, it is only necessary to rotate the crank shaft 37 sulliciently to draw the wings under the loader or auxiliary chute, so that the auxiliary chute can pass under the discharge end of the primary chute 12, and then by hooking a lin. of the chain over a hook 40, Fig. 6, attached to the upper or inner end of the loader 18, the loader will be drawn inward to the position shown by dotted lines 26, thereby placing said loader or auxiliary chute under the primary chute.

Vertical straight brackets 41 are fixedly secured tothe sides of the primary chute 1.2, near its discharge end, and journaled in these brackets is shaft 39, the shaft 39 being placed under the primary chute, and wheels 42 are journaled upon these brackets, upon which wheels travel the angle members 27 of the loader 18. Secured to the upper end of each vertical bracket 41 is a chain 43, which chain is passed over a grooved wheel or pulley 11 and attached to the opposite end of the chain, is a counter-balanee or weight 44, whereby, when. the primary chute 12 is adjusted to its desired position, preparatory to loading a car or vehicle, the same will be held in said position by the weights 44. It will be obvious that two weights or counterbalances are used, as there are two chains employed and two pulleys 11.

When it is desired to raise the primary chute 12, carrying the longitudinally adjustable loader, this may be accomplished by employing any suitable means, as for instance, a cable or rope shown by dotted lines 45, may be connected by any suitable means, near one end, to the brackets 41, and its opposite end wound or fastened to a Windlass or winch shown by dotted lines 4-6. By operating the windlass or winch 46, the primary chute and the loader will be moved.

From the foregoing description, it will be noted that I have constructed a loading apparatus, which comprises a pivotallymounted, primary chute capable of being adjusted upon a support relative to the receptacle, or body of a car, that is to be loaded, and that said primary chute carries an adjustable loader or auxiliary chute, which loader is provided with wings or plates capable of being laterally projected, so that the load can be spread over a large area of the body of the receptacle that is to be loaded. The wings facilitate the distributing of the load, so that it will not be deposited in one place nor choke the entrance to the vehicle when said entrance is in the nature of a side-opening of an ordinary box-car. j

The balance weights are placed one on each sideo fthe chute 1'2, and attached to either weight, is a pulley, to which isattached a chain, or other suitable connecting means, fastened to a winch or Windlass, for the purpose of raising or lowering the chute.
