JAMES BENTON SCHAUB,
HOISTING Application filed November To (ZZZ whom it may concern Be it' known that 1, James BENTON SCHALIP, a citizen of the United States, and a a resirflcnt of the city oi? Evanston, in the county of Cook and State of Illinois, have invented certain new and useful Improvements .in a Hoisting Conveyer; andl do hereby declare that'the following is a full, clear, and exact descriptionof the same,
reference being had to-the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification.
' My invention relates to a conveyer pri marily designed for handling cinders, but
susceptible of conveying any other ma terial that is desired to convey from some I point .to a dumping 'pit or a car and dump the same.
In the past these conveyers have been constructed. to operate over inclinesnecessitating a large area of ground'for their installation. In other cases, elevators have been used. In both instances, the conveying car cannot be readily dumped or emptied and much time is consumed. To overcome these objections, I havedevised a tower that is perpendicular, thus occupying very little space, andallowing the cinder dumping car to serve a niuch wider area, making it possibleto serve several lines of railroad. track, where only one could be served before. Further, I have provided a structure that automatically dumps the conveyor car in a very simple way, and have provided a very compact and serviceable arrangement that saves much time, labor and expense. I It is therefore an object of my invention to provide a structure that covers but little I area that automatically dumps the conveyer car in a novel way, that is quickly and readilyoperable and that possesses many advantages over prior structures as will become more apparent in the following descriptionand disclosures in the drawing.
My invention is disclosed in the accompanying drawings and hereinafter more fully described and pointed out in the appended claims. In the drawings:

Figure 2 is a section on the line 2-2 of Figure l.
Figure 3 is a fragmentary'sectionshowing the arrangement of the track, on "an enlarged scale over the showing in Figure 2. I Figure 4 is a section on the line 4--.4 of Figure 1-, showing in plan view an arrangement of railroad tracks.
Figure 5 is a side elevation of an operating mechanism that may be used in connection with my apparatus. a
Figure 6 is a top plan view of Figure a reversing motor.
Figure 8 is a ground section somewhat similar. to Figure 1 but illustrating a slight modification.
As shown on the drawings:
In the diiierent figures of the drawing, similar features are denoted by similar reference numerals.
For the purpose of illustrating my in vent'ion, have shown a plat which might consist of a part of a railroad yard having a plurality of pairs of tracks 1 and 2 over which engines can be drawn above a cinder pit or runway 3, or the like, in order to have the ashes and cinders removed there from. The numeral 4 represents such an engine in position to have its cinders removed. My invention comprises a specially constructed conveyer car 5, adapted to pass under the engine to receive the ashes and cinders, and a novel form, of track arrange ment over which said car can be hauled and elevated and dumped into a gondola car 6, such as illustrated adjacent the tower in Figure 1, and an endless traveling device "attached to said car for hauling the same.
It is obvious that my invention is susceptible of being used to haul,elevate and dump any material or cargo into a car or receptacle and that any mechanic can adapt. it -tor a particular purpose or use consistent with the description thereof. In the present instance in which my invention is shown as adapted for hauling and dumping cinders removed from railway engines, a sunken runway 3 built of concrete or the like and leading under the car is provided. The runway 3 also leads adjacent the receiving car or dumping pit, at which point a hoisting tower is provided which can be constructed in any suitable manner such as by spaced Figure 7 shows a scheme for operating channel members 6 (see Fig l) which are properly braced and connected together by struts 7 and braces 8, or the like, to provide a rigid tower of such dimensions as to freely allow the car 5 to be rolled or elevated thereup. The construction of the tower is immaterial. It should, however, he designed with reference tothe tracks it has to support and the work and functions it has to perform. Accordingly, if have so designed the frame work of the tower so that a pair of vertically arranged main tracks 9 which may be in the form of angle bars can be directly attached to these channel members 6 which are nearest, the dumping pit or car. The tracks 9 preferably extend from the top of the runway to approximately the top of the tower and are secured in place in any approved manner.
Cooperating with the tracks 9 to supper and guide the conveyer car is a second pair of vertically arranged main tracks 10, which likewise may consist of angle bars attached to the struts 8 or frame work. The height of these tracks 10 are so designed as to afford a convenient dumping point from the side of the tower, and are provided at their upper ends with curved guiding or transfer portions 11.
These curved portions '11 are termed guiding or transfer portions since they guide the conveyer car outwardly at that point and transfer it to a pair of auxiliary or dumping tracks 12 (only one of which is shown) attached to the tower and projecting beyond the dumping side thereof to provide a dumping platform at a predetermined point properly located below the operating mechanism. These auxiliary tracks are of curved formation corresponding to the curved portions 11 and are. spaced from the curved portion an amount equal to approximatelythe diameter of a wheel. of the conveyer car. should be noted at this point that Figure 1 shows the far side of the tower, and thatthe tracks 9 and 10 are spaced on a diagonal line, the track 1.0 being further inward and further forward toward the receiving side of the tower, and as the tracks 9 support the rear wheels of the car which are mounted on an extended axle, as shown in Figure it is necessary to provide a way 13 through the tracks 11 and 1:2 for the axle during the tilting; movements of the car. It will be understood that the tower is nimetrical and that the near side has the same con strnctiou and tracks as the illustrated far the engines to the tower where they are bent or curved upwardly and merge with the tracks 9.
Above the tracks l t, there is a second pair of horizontal main tracks 15 similar to the tracks it but located in the wall at av point inward from the tracks 1a. The tracks 14: and 15 bear the same relation to each other in respect to the spacing thereof as the tracks 9 and 10. The tracks 15 also extend to the tower and are bent or curved upwardly at 16 as the tracks 1%, but they are not joined to the tracks 10. Insteadthe curved or bent ends are spaced from the lower ends of the track 10 an amount equal to substantially the diameter of a wheel of the car 5, and the lower ends of the tracks 10 are correspondingly bent as shown in Figure l. These lower bent or curved portions guide the car upwardly and the curved ends 16 also serve totransfer the car or wheels to the tracks 10 as is obvious.
V The system of tracks is so constructed that the continuous or main tracks comprising the horizontal portions l i and vertical portions 9 support the rear wheels 17 which are iournalled upon the extended axle 18,
and the tracks 15, 10 and 12 support the side wheels 19 which are mounted on trunnions 20 supported in the side walls of the car substantially near the center point thereof 7 For the'purpose of operating the conveyer car 5. I have illustrated endless memhers 21 which may consist of chains or the like trained over pulleys 22 at the far end of the runway. The endless members are secured to the rear axle 18 onopposite sides of the car, as by bolt pins 23 projecting from opposite, sides of supports 24 rigidly secured to the axle. The endless members 21 extend in the runway to the tower where guide pulleys or rollers 25 are provided to properly direct the endless member's vertically up the tower where they are trained over sprocket wheels 26 keyed on a shaft 27 supported in a housing 28 near the top of the tower and above the dumping point or in any other convenient place. The housing may be supported by means of channels secured around the tower and the shaft $37 may be journalled in bearings supported. by I beams resting upon the channels. The shaft is contemplated to be driven by a .iotor hearing: driven by worm on shaft 33. n order to stop and reverse the drive at the upper and lower limits of travel of the conveyer car it is contemplated that a reversing motor be used. The motor may be reversed by means o a screw shaft 34 (see Figure 7 the main shaft 27- by gearing and having a traveling; nut 35 which has afinger or projection 36 to shift a switch or :29, gears 30 and 31-andthe worm operated by isc which receives the cinders or cargo to be carried thereby may be varied. Thus in Figure l, I have shown a carhaving an open front end which slopes downwardly,
and a portion of the top of the car is open to receive the cinders or material to be carried, and in Figure 8 I have shown a car having merely an opening in thetop to receive the material, the front end being closed by a door 34L hinged at its upperend but maintained in a closed position by means of an arm secured thereto and having a" roller or spherical head 36 riding directly under a member 37. Thus the door will be f held closed until the car assumes an upwardly tilted or vertical position when the pressure on the door is released.
The operation is as follows: As the operation of the car is controlled by the motor, it is only necessary forthe operator to control the current. Assuming "now that the car is in the illustrated posi tion and has been filled with cinders, which have been shoveled from the engine through the hopper 38, if the current is turned on, the endless members will travel around the sprocket wheels which are rotated by the aforedescribed gearing. The. car will hence be drawn to the tower on the tracks 14L and 15 ascending the curved or bent portions, the bent portions 16 guiding and transferring the center side wheels 19 to the tracks 10. As the carwheels 19 reach the guiding and transfer portions 11, they will be transferred to the auxiliary tracks 12 and guided outwardly as is obvious, the axle 18 passing,
through the passages 13, as the endless members raise the rear end of the car to tilt the same. Hence the car can be said to be rolled up thehoisting tower. The car will be tilted on the side wheels which rest upon the auxiliary tracks 12 and act as pivotal. fulcrums, and the contents of the car will accordingly be dumped, and as the auxiliary tracks extend well beyond the side of the tower, the
contents will fall clear of the tower and have provided a conveyei' or hoistthat uses a vertical tower in which the car is drawn up, in which certain tracks are provided with gu ding and transfer portions to guide the car onwardly on extending auxiliary or dumping tracks, giving a compact arrange ment that utilizes but little space, and can hence be employed where the inclined type of conveyer is imprat-icable.
1am aware that numerous details of construction may be varied through a wide range without depart ng from the principles of this invention, and I therefore do not purpose limiting the patent granted otherwise than necessitated by'theprior art.
