SPECIFICATION forming part of Letters Patent No. 78d,108, dated March '7, 1905.

Application filed February 12, 1904:. Serial No. 193,345.

To all whom, it TIMI/,7] concern.

Be it known that we, l/VILLIS H. FISHER, a resident of Memphis, in the county of Shelby and State of Tennessee, and IIENRY B. Hnmi and ,G-noneu ErPLn, residents of Shreveport, in the parish Cad do and State of Louisiana, citizens of the United States, have invented new and useful Improvements in Hydraulic Hand-Cars for Railroads, of which the following is a specification.

Our invention relates to a hydraulic construction or reconstruction hand-car to be used on railroads, and the main object that we have in View in producing such a hand-car is to reconstructand even up railroads where such have become irregular and unlevel from the weight of the cars which travel over said roads.

Our invention is so constructed that sunken or settled portions of the road can be readily grappled and raised without the use of handspikes or crowbars.

Figure 1 is a side elevation disclosing one side of the hand-car in position on a rail, also the position of one of the hydraulic rams, of which two are employed for raising the track on each side of the road at the same time. Fig. 2 is a cross-section of the car, showing the two rams in vertical section. Fig. 3 is a plan view of our construction, showing the location of two hydraulic rams located centrally between the four wheels oi? the car, also the location of a force-pump employed for forcing water into the two rains at the same time.

With the above description we will now proceed to more fully describe our invention by referring to the corresponding characters on the drawings and the specification and will first describe the route of the water from a watertank 1 to the rams and its return back. to said tank. The numerals, commencing with 8, will correspondingly indicate the route of the water from T-joint 7 to its entrance in each of the large ram-cylinders, and corresponding numerals will indicate the route of the water from this point to the small rams,

l and also corresponding numerals will indicate the return of the water from the rams back to the tank.

A-force-pump 2 is placed on the top of the platform of the car-3 innncdiately over the tank, with a suction-pipe 4 connected to the lower end of said pump and extending downward within a short distance from the bottom of the tank. lhe pump is next started by an upwardand-downward movement of the handle 5. The water is then drawnu p through the pipe and is forced out through pipe 6, which connects to a T-joint 7. From IF-joint 7 it is forced each way through pipes 8, said pipes connecting elbows S). Extending from said elbows i) are pipes 10, which connect elbows 11. Extending from said elbows 11 are sections of pipe 12. Said pipes 12 connect to elbows 13. Said elbows 13 connect to vertical pipes 1 1. ((llearlyindicated at Fig. l.) Said pipes connect to IF-joints 15. From said 1- joints, connecting with the upper ends of the hydraulic rams proper, are short sections of pipe 16 Secured to said sections 16am oneway valves A. Extending vertically from said T-joints 15 are sections of pipe 17. Connected to said sections are elbows 18. Extending from said elbows in and connecting to ram extensions 19 are horizontal sections of pipe 20. Connected to said horizontal sections 20 are one-way valves B.

We will now describe the route of the water from the respective rains back to the watertank 1. Extei'iding from ram extensions 19 are short sections of pipe 21. To said sections of pipe 21 are one-way valves. Said sections connect to elbows 22. .ltlxtending from said elbows are short sections of pipe 23, con.- necting to T-joints 24. This brings the water back from ram extensions 1%) to vertical pipes 14, clearly described. Leading from the hy draulic rains proper to "l"-joints 2 1 are short sections of pipe 25. (Jonnected to said short sections are one-way valves 1.). Extending from said T-joints 24: and coi'n'iecting with elbows 26 are vertical pipes 14-. From said elbows 2.6, connecting with elbows 27, are short sections of pipe 28. From said elbows 27 and extending back to and connecting with watertank 1 are sections of pipe 29.

e will now proceed to describe the construction of the rams 30 and 30. Corresponding numerals will indicate the corresponding respective parts of each. These are each provided with piston heads 31. Said pistonheads are hollow the greater part of the length thereof and are provided with extending legs 32, adapted to extend down to the ground. Each of said legs is forked, as plainly indicated at Fig. 1. Attached to their lower ends are feet or shoes 33. Said pistons a sufiicient distance above said forks are provided with crossbeams 34. Connected to said crossbeams are depending cars 35. Pivotally secured to'said depending ears are depending grapplinghooks 36. These hooks extend downward and are adapted to engage the under side of a railway-rail, as shown. Secured to said extending legs 32 at the forks thereof referred to are chains 37, the lower ends of which are secured to the lower ends of the depending hooks 36. Said piston-heads 31 are further provided with circumferential pistonrings 38. Secured to the upper end of said piston-heads 31 are vertical piston-rods 39. Said rods extend upward through the tops of the rains proper and through the bottom of the ram extensions and are connected to pistonheads 10 in said ram extensions 19.

The operation of our invention is as follows: The machine is placed upon the railway-tracks. Tank 1 is filled with water. Pump 2 is put in motion by an upward-anddownward movement of the handle 5. The water is drawn up from tank 1 to pipe 1 and forced out through pipe 6, where it extends each way through pipes 8, from pipes 8 to elbows 9, through pipes 10, through elbows 11, through pipes 12, through elbows 13 and up through pipes 1 1 to T-joints 15, from T-joints 15 through short pipes 16 to hydraulic rams 30, but continues to ram extensions 19, through vertical pipes 17, through elbows 18, and through pipes 20 to ram extensions 19, when the machinery is in the position indicated at Fig. 2. For raising and leveling the sunken portion of the track, but before the water enters the water-chambers 41, the one-. way valves B and D are closed. This will prevent the water from entering ram extensions 19 anddischarging from rams 30. WV hen this is done, the water is to pass in through valve A to the water-chambers 41. This will bring to bear a pressure between the upper ends of the piston-heads 31 and the top of the rams 30, and by the feet 33 on the extended legs 32 being on the ground the car with the hoisting apparatus will 'move upward, carrying the tracks with it, as indicated,in the direction by dotted lines, from the fact that the grapplehooks firmly grapple the under side of the chains 37.

rails, which are usually spiked down tight to the ties. hen the sunken portion of the tracks is in this position, the earth and ballast is stamped in under the ties, when the machine is ready to move on to the next low point.

We will now describe the purpose of the ram extensions 19 in connection with the Before the car is moved to another defective part of the track it will be necessary for the grap1')lehooks to be raised to a position sufficient for the lower ends of said hooks to pass over the top of the ties. In order to accomplish this, the one-way valves A are closed and the two-way valves are open. Then with a few wrenches on lever 5 of the force-pump 2 the water is forced into ram extensions 19 between the lower ends thereof and piston-heads 10. Said piston-heads 4E0 are forced upward, which raises piston-heads 31 of the rams proper. In this operation the chains 37 cause the grappling-hooks 36 to spread outward between the forks of the extending legs sufficiently far to let said grappling-hooks pass over the tops of the ties.

In order to let the water discharge from the water-chambers 31, the one-way valves D are open, and in order to let the same discharge from the lower ends thereof ram extensions 19 and the one-way valves C are open.

Having now fully described our invention, what we claim as new, and desire to secure by Letters Patent of the United States, is
