Specification of Letters Patent.
Patented Feb. 9, 1915.
Application filed December 15, 1913. Serial No. 806,918.
To all whom it may concern Be it known that we, MARIANO P. SCAR- DINO and PETER SCARDINO, citizens of the United States, residing at Bryan, 1n the county of Brazos, State of Texas, have 1nvented certain new and useful Improvements in Half-Car Unloaders; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to the handling of material in bulks and has special reference to a device arranged to enable railroad cars such as are used for handling coal, ore and other like material to be unloaded by a single operation.
The principal object of the invention is to improve and simplify the general construction of devices of this character.
A second object of the invention is to pro vide an improved apparatus for hoisting a car, moving the car ofi' the track in 2. lateral direction when hoisted, and then dumping the car and replacing it upon the track.
A third object of the invention is to provide an improved means for controlling the hoisting and dumping operations of a device of the character described.
A fourth object of the invention is to provide an improved derrick or crane for accomplishing the objects hereinbefore set forth.
A still further object of the invention is to provide a portable crane arranged to accomplish the hoisting and overturning of a car in order to dump the same.
With the above and other objects in view the invention consists in general of certain .novel details of construction and combination of parts hereinafter fully described, illustrated in the accompanying drawings, and specifically claimed.
In the accompanying drawings, like characters of reference indicate like parts in the several views, and Figure 1 is a side elevation of one form of the invention, showing the same applied to a flat car for easy transportation. Fig. 2 is a plan view thereof. Fig. 3 is a section on the line 3-3 of Fig. 2. Fig.4 is a section on the line 44 of Fig. 1. Fig. 5 is a section on the line 5-5 of Fig. 1. Fig. 6 is a front elevation of the device.
In Fig. 1 there is shown a flat car 10 of the ordinary type. on this car adjacent one end is mounted a gear 11 which is preferably called the turntable gear. is fixed to the car floor, being provided with suitable slots 12 which receive lugs 13 arising from the car floor. Centrally disposed of the gear ll'is a heavy shaft 14 forming the turntable shaft or pivot and on this shaft is mounted the turntable 15. Mounted in a suitable'bearing 16 carried by the turntable 15 is a shaft 17 whereon is fixed a gear 18 arranged to mesh with the gear 11.
'This gear 18 is thus below the turntable while the shaft extends up above the turntable and is provided with a worm gear 19 at its upper end. This worm gear 19 meshes with a Worm 20 which is carried on a shaft 21. supported in suitable bearings 22 mounted on the turntable 15. Other bearings 23 are also provided on the turntable15 and serve to support a shaft 24 which is termed the jack shaft and which is connected to the shaft 21 by means of a belt 25 running over pulleys 26 and 27 located respectively on the shafts 21 and 24. On the jack shaft 24 is also located a belt pulley 28 which serves as the driving pulley of the mecha nism, being belted by means of a belt 29 to any suitable source of energy as for instance the motor 30 located on the turntable. Mounted on the turntable over the gear 11 is the crane. This crane consists of a pair of spaced side members 31 from which projects thejib 32. These side members are connected by suitable braces 33 andthe tops of these side members are connected to the rear portion of the turntable by means of the braces 34. Extending between the side members 31 are the shafts 35, 36 and 37 which are supported in suitable bearings 38. On the shaft 35 is a sprocket wheel 39 which is connected by means of a chain 40 with a similar sprocket wheel 41 mounted on the shaft 36. On the opposite end of the shaft 36 there is provided a sprocket 42 which is connected by means of a chain 43 with a sprocket 44 on the shaft 37. On this shaft 37 is also provided a belt wheelor This gear.
Mounted on the respective shafts 35, 35 and 87 are the winding drums 58, 5 and 55 which are arranged to be connected to their respective shafts by means of the clutches 56 controlled by the clutch levers 57. Each of these winding drums is also provided at one end with a suitable brake drum or rim 58 which is controlled by means of a suitable brake lever 59. Carried by the jib of the crane are the pulleys 60 over which run the chains or cables 61, the latter being led to the winding drum 53. Lateral pulleys 62 are also provided which are spaced apart and over which are trained the respective cables or chains 63 which run respectively to the winding drums 54: and 55. Each of these chains or cables is provided with a suitable hook. 64.
In the operation of the device the chains or cables 61 are attached by their hooks to each end of the car to be dumped. In like manner the hooks of the chains or cables 63 are attached to opposite sides of said car. Now, upon clutching the pulley 47 to the jack shaft and braking the other pulley on said shaft the several sprockets and driving connections will serve to operate the respective shafts 35, 36 and 37. Now when all the connections to the car have been made the brakes on the winding drums are released and the clutches 56 thrown in. This causes all of the winding drums to hoist simultaneously. "When the desired height has been reached the brakes on the winding drums are applied and the clutches simultaneously thrown out. This holds the car at the desired height. Then the pulley 17 has its brake applied being at the same time unclutched from the jack shaft while the remaining pulley on the jack shaft is clutched to the shaft and its brake removed. This causes the crane to swing to one side or the other as may be desired, this being regulated by the direction of drive of the motor. W hen the crane has swung sufficiently to one side or the other the pulley 2? is unclutched and its brake applied while the pulley 47 is again clutched to the jack shaft and its brake removed so that it may be driven. Now by clutching either the drum or the drum 55 to its respective shaft one side of the car may be pulled up while by releasing the brake on the remaining one of said drums 54 01 55 the other side of the car may be lowered. In this way the car may be dumped. It is obvious that by reversing the operation the car may be restored to its position on the track.
It will be obvious that many minor changes may be made in the form and con struction of this invention without departing from the material principles thereof. 1],
is not therefore desired to confine the invention to the exact form herein shown and described, but it is wished to include all such as come properly within the scopeclaimed.
Having thus described the invention, what is claimed as new, is:
1. In a crane, a post, a plurality of shafts, bearings on said post supporting said shafts, gearing connecting said shafts for simultaneous movement, a drum on each shaft, clutches each adapted to connect a respective drum and shaft, a brake for each drum, a plurality of hoisting cables wound on one drum, and tilting cables each wound on a separate drum.
