POWER-SHOVEL FOR LOADING BOX-CARS.

SPECIFICATION forming part of Letters Patent No. 794,946, dated July 1'8, 1905.

Application filed September l2, 1904. Serial No. 224,134.

To all whom it 11i/(ty concern,.-

Be it known that I, JACOB OLSON, a citizen of the United States, residing at Albia, in the county of Monroe and State of Iowa, have invented certain new and useful Improvements in Power-Shovels for Loading B0X-Cars, of which the following' is a specification.

It is well known that the ordinary type of railroad box-cars are seldom used to carry material in bulk-'#such as coal, crushed ore or rock, or the like. rl`he reason for the above is the difficulty which is necessarily incurred in accomplishing the loading operation; and it is therefore the essential object of this invention to provide a power-machine by which cars of the type mentioned may not only be conveniently loaded, but such operation is facilitated to a maximum degree in practice.

The invention is chiefly designed for loading coal, though its usefulness is not by any means limited to the above, and comprises,

primarily, a horizontally-movable support or carriage and a power-operated shovel mounted upon said support and adapted by operation of the carriage to be disposed within the boili-car to be loaded or iilled with the materia The invention further resides in the special construction of the shovel before mentioned and the means for operating this device whereby the material being loaded when fed to the shovel may be thrown thereby into the eX- treme ends of the car, so that the same may be filled to ,its greatest capacity, and regulable means is provided for varying the directionl in which the material may be expelled or thrown from the shovel, the advantages of which last feature will very forcibly appear as the detailed description is entered into.

In addition to the foregoing the mounting of and the actuating means employed to effect the desired movement of the carriage and to govern such movement form an important feature of the invention.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and accompanying drawings.

While the essential and characteristic features of the invention are susceptible of modiiication, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which- Figure l is a view in elevation, showing a machine embodying the invention. Fig. 2 is a top plan View. Fig. 3 is a section on the line X X of Fig. 2, showing the engine and adjacent operating mechanism. Fig. 4 is a vertical sectional view taken about on the line y y of Fig. 1, showing the means for operating the shovel easing or deflector. Fig. 5 is a view looking toward the open end of the shovel-casing bringing out more clearly the construction of the shovel. Fig. 6 is a broken sectional view bringing out clearly the mounting of the shovel-casing upon the adjacent standard.

Corresponding and like parts are referred to in the following description and indicated` in all the views of the drawings by the same reference characters.

In its general organization a loading-machine constructed in accordance with the invention comprises a horizontally-moving support l, a shovel 2, mounted thereon, an engine 3 or other class of motor for operating the shovel, and the horizontal moving support or carriage l. As before premised, the invention is utilized, preferably,for loading coal into box-cars, and in order to accomplish the above the carriage l, which supports the general operating mechanism of the machine, is mounted upon a suitable foundation 4 above the normal level of the track 5, over which the cars or rollingstock passes. The above dispositionof the horizontally-moving support l is necessary in order that the shovel 2, which is mounted at one end thereof, may be caused to enter the door-opening usually provided at the center of the sides of the car, and when in such position said shovel is then adapted to throw the material fed thereto lengthwise of the car at an angle to the movement of the support l. The support or carriage 1 is mounted in guides or ways formed in blocks 6, suitably and substantially anchored in the foundation 4, upon which the machine rests, and the support is adapted for transverse or horizontal movement, so as `to be projected laterally from its .foundation to partially enter the body of the car to be loaded after the car has been moved into a position alongside the machine. The support 1 itself may be of any substantial construction and preferably consists of a pair of longitudinal I-beams 7, rigidly connected by the base of the support, and this base may comprise any preferred construction of platform 8 suitable for the purposes of the invention. At one end of the support or carriage 1 is located the engine 3, which latter is of any approved type having a suitable reversing mechanism.A Mounted longitudinally of the support 1 is a main shaft 9, disposed upon 'standards 10, projected upwardly from the base 8 of the carriage, and said standards 10 are provided with suitable bearing-heads 11 for the shaft 9 aforesaid. The shaft 9 is rotated by the engine 3, the latter being operably connected therewith, and a balance-wheel 12isused. Theengineisoperablyconnected with the shaft 9 atits inner end, and upon the outer end of the shaft is mounted the shovel 2, the latter being rotatable and consisting of a plurality of blades or wings 13. The shovel 2 is partially inclosed by means of a casing 14,the latter being open at its front portion and at the upper portion thereof. The outermost standard 10 consists, preferably, of a casting provided at the upper portion with a boss 11, through which the shaft 9 passes, and this boss is of circular formation, so as to constitute a journal for the casing 14, the rear wall of said casing being provided with an opening receiving the boss mentioned above, thereby affording a bearing for the casing and admitting of 'rotation ofa certain amount of rotatory movement of the casing.

Special operating mechanism is used for advancing the carriage or support 1 to cause the outermost end thereof to project beyond the side of the foundation 4 in the body of the car to be loaded, and for this purpose a transverse shaft 15 is mounted upon the support 1 below the shaft 9, before described, and a gear-wheel 16 is located about centrally of the shaft 15 and keyed thereto. The gear-wheel 16 is adapted to mesh with a worm 17, keyed to the main shaft 9, and when in mesh with said worm during the operation of the shaft 9 motion will be communicated to the shaft 15 therefrom. The shaft 15 has end sprocketgears 18 keyed thereto at its ends, and said gears cooperate With fixed sprocket-chains 19,

which latter are rigidly attached to the blocks 6, in which the support 1 is mounted. The `shaft 15 is vertically movable, being mounted in eccentric bearings 20, supported by the car- Lriage or support 1, and the vertical movement of said shaft is governed by an operating-lever 21. The operating -lever 21 by a pivotal movement thereof will so actuate the eccentric bearing-disks in which the shaft 15 is mounted as to raise or lower said disks, and this movement of the shaft is designed to throw the gears 16 and 18 out of mesh with the respective parts 17 and 19 or into mesh with said parts. the gear 16 meshes with the worm 17 motion is communicated to the shaft 15, and also when the gear 16 is in the position mentioned the end gears 18 engage the sprocket-chains 19, so that revolution of the end gears through cooperation with the sprocket-chains will effect a horizontal movement of the support 1 in either direction, and said movement may be reversed at will by the engineer having charge of the engine 3. When the support 1 has been adjusted horizontally to the desired position, the lever 21. is operated to throw the gears 16 and 18 out of mesh with adjacent cooperating parts, so that the support 1 may remain stationary while the shaft 9 is still revolving under actuation of the engine 3. rlhe shaft 9 is designed to constantly revolve when the machine is in use, so that the shovel 2 will be in constant operation also.

The shovel-casing 14 has been described as adjustable, being adapted for revolution, as set forth, and the means for effecting the above actuation of this part 14 consists of a secondary shaft 22, mounted in suitable bearings in the horizontally-moving support 1 lengthwise thereof. The shaft 2 extends almost the entire length of the support or carriage 1, and,

the inner end of the same is located adjacent the engine 3. A ratchet-wheel 23 is carried by the inner end of the shaft 22, and a ratchetlever 24 is adapted to operate the wheel 23, so as to effect revolution of the shaft 22 manually. The outer end of the shaft 22 is provided with a sprocket-gear 25, which gear has its teeth in mesh with a sprocket-chain 26, the ends of which are attached to pins 27, projected from the rear wall of the casing 14. The wheel 25 engages the chain 26 at a point between the ends thereof, and rotation of said gear will cause travel of the chain in a manner which will be readily comprehended. The chain 26 being permanently attached to the shovel-casing 14 at points upon opposite sides of the center of the axis upon which said casing rotates will ytherefore effect rotary movement of said casing upon actuation of the shaft 22. It is designed that the rotary movement of the casing 14 shall be suflicient to cause the open upper portion thereof to be disposed in various directions, dependent upon the amount of rotation of the casing. The adjustability of the casing 14 is essential, since this casing serves as and constitutes a deflector for directing the material operated upon by the shovel 2 into a certain portion of the car It will be noted that when IOO IIO

which is being loaded. In other words, when the open upper end of the casing 14 is toward one end of the car in which the shovel is received the material as it is operated upon by vthe shovel will be directed toward one end of said car, and vice versa.

In the operation of the invention preparatory to use of the machine the car to be loaded is moved alongside the foundation 4, upon which the machine rests in an elevated position. To commence the loading operation, the engine 3 is started and the lever 21 is operated so as to cause the shaft 15 to be thrown into motion through the gear-chains hereinbefore described, and motion being communicated tothe shaft 15 the carriage or support 1 is actuated horizontally, so that the outer end thereof enters the body of the car. The shaft 9 of course is revolving constantly, actuating the shaft 2, and when the shovel end of the carriage reaches the desired position within the car-body the lever 21 is so operated as to discontinue its movement. A chute or like conveyor is utilized to convey the material to be loaded into the car to the shovel 2. As the material falls into the casing 14 the constant revolution of the shovel causes the material to be thrown or expelled at an angle to the line of movement of the support 1, and sai'd material will thus be thrown into the end of the car toward which the open end of the casing 14 is disposed. When one end of the car has been filled to its limit, the operator grasps the lever 24 and by actuating the shaft 22 rotates the casing 14 until the open upper end thereof is direct.- ed toward the opposite end of the car, at the same time reversing' the engine and the'direction of rotation of the shovel 2. The lastmentioned end of the car is now filled, and.

the operator in the loading operation can readily adjust the position of the shovel and casing 14 so that the material will be thrown gradually as it is banked at the ends of the car. The loading operation having been finished, the lever 21 is again operated and the engine reversed, so as to' cause the horizontally-moving carriage to move away from the car, the feed of the material to the shovel 2 having been previously cut off. In order to sustain the weight of the carriage 1 as same is moved rearwardly upon the foundation 4,

a suitable roller 28 is mounted in rear thereof, over which the carriage freely operates. The construction of the shovel 2 in the provision of the wings or blades 3 is advantageous in that positive means for forcibly expelling and throwing the material is attained. It

will of course be understood that when the shovel 2 is not in motion the material is fed directly from the open end of said casing 14.
