Application fiIedJ'uIy ZZ, 1902. Serial No. 116,530. (No model.)

To allwhom it may ohn'cern: p 1 Upon each side of the car or carriage 1 are Be it known that I, ERNEST O. SPRINGER, a l ar ranged vertical standards 3 3, rising from citizen of the United States, residing at Mason the bottom of drop 2andsupporting horizon- Oity, in the county of Oerro Gordo'and State taltransverse beams'4c4, suitably spaced apart 55 of Iowa, have invented certainnew and useful and carrying at each end a beam 5, arranged Improvements in Machine's for Tamping Rail-' longitudinally of the car, but transversely of road-Ties; and I do hereby declare the followthe beams 4t.

In' the accompanying drawings, Figure 1 carried by a piston-head 20 within the cylinrepresents a top plan view of a tamping or der 14. The framework 17 fits within its re- 0 4o spiking mechanism embodying the features spective guide 6 and is adapted to be adjusted of the present invention, parts being broken ftowvarious planes by the adjustment of said away. Fig. 2 represents a View in sideel'eguide longitudinally of its beam 5, the framevation of the same. Fig. 3 represents a dework 17 swinging upon the pivot of the cyltail view of the tamping-plungers. Fig. 4 repinder 14:, the guide 6 being pivotally attached 5 resents adetail View of the tamper-supporting to its-adj usting-lever 8. Each cylinder 14 is beam. i provided with'an intake-port 20, preferably Referring to the drawings by numerals, 1 connected by anysuitabl'e flexible connection indicates any suitable carriage, preferably in with any suitable source of supply, a slide 21 the form of a car provided with the usual controlling the admission of pressure to the r00 flanged wheels and formed with a drop or decylinder through said port. A bracket 22 is pending portion 2 intermediate of its length. secured, preferably, to the end of the cylinder 14 and carries a pivotally-mounted operating arm 23,attached to a bell-cranklever 24,which has its free end -slotted and engaging the stem of the valve 21 and inclosing any suitable stud carried by said stem. A suitable bracket 26 guides the movement of the free end of the stem 25, and a suitable spring 27 is interposed between said bracket 26 and the slotted end of said bell-crank lever. Asuitable spring 29 is arranged, preferably longitudinally ofthe piston-rod 19, within the framework 17 and connected with said rod for moving the same longitudinally upward.

A red 28 extends upwardly from the piston 19 and engages the lower face of operatingarm 23, so that the upward pull of spring 29 normally causes said rod 28 to lift arm 23 and admit steam into the cylinder 14. Immediately upon such admission of steam the piston 19 moves downwardly, permitting the spring27 to act on lever 24 and close the intake 20, at the same time opening any suitable eXhaust-port, which may be a common tube, as indicated in Fig. 2, the valve not being shown. By this arrangement it will be seen that when pressure is supplied to the intake-port 2O the piston 19 will be automatically reciprocated with comparatively short strokes and in rapid succession.

Each beam 5 rests by weight upon beams 4 4 and may be moved laterally thereon.

Suitable supply-pipes 30 30 lead to the respective ends of each of the cylinders 10, suitable three-way valves 31 31 being interposed in the length of said supply-pipes and provided with operating-handles 32 32 for controlling the admission of pressure to said cylinder. It will thus be seen that pressure'may be'introduced into each cylinder 10 for liftingthebeam 13 carried thereby and with it the plungers 18 and their operating mechan ism, so as to raise the same to a horizontal plane above the rail upon which the wheels of the car or carriage rest. The beams 4 4 are provided with rack-bars 33 33, and each beam 5 is provided with a pinion 34, meshing with its respective rack-bar 33, any suitable means, as a crank 34*, being provided for r0- tating said pinion, whereby the parts raised by'the movement of the piston-head 11, as above described, will be moved inahorizontal plane for the required distance. After such movement the valve 31, controlling the supply to the loweirend of the cylinder 10, may be reversed for permitting the exhaust of the steam from the cylinder, and pressure may then be admitted into the opposite end of the cylinder for bringing the parts down to their normal horizontal plane.

In practice I may provide any suitable pressure-supply tanks 35 35 or may employ any other source of supply for the operation of the parts described.

It is believed that the operation of the present improved tamping or spike device will be readily comprehended, the same being somewhat as follows: The car or carriage 1 is moved by means of a motor carried thereby or any other suitable source of power to the point of operation, when the piston-head 11 is forced to the lower end of the piston 10, bringing the tarnping-plungers 18 into position upon their respective sides of the tie. Fluid-pressure is supplied to the cylinders 14, a series of short rapid strokes of the plungers is produced, and the road-bed will be readily tamped, the movement of each pair of tamping-plungers being preferably approximately simultaneous, so'as-to crowd the ballast or other substance in opposite directions beneath the rail at the same time. When it is desired to employ the device as a spiking means, it is only necessary to raise the plungers 18 to a slightly higher plane and cause them to strike the heads of the spikes to be driven. If it is desired to alter the angle or incline of the plunger 18, the guide 6 is moved longitudinally of the beam 5 and locked in position by the pawl'7 engaging the desired notch of the series of notches 9. However, it may be found desirable to swing the lower end of the plunger 18 to an angle greater than will be permitted by the adjustment of the guide 6, and the same is accomplished by a movement of the cylinder 14, the lever 15 being slid along its respective slot 13 It will be seen that by this means the camping-plunger may be moved from a diagonal plane in one direction to a plane of an equal angle in the opposite direction, a great deal of freedom thereby being permitted in the use of the tampers, whereby the tamping of the road-bed is greatly facilitated. It will be further observed that each'plunger 18 may by the proper adjustment of its supporting parts be caused to assume a vertical plane and may be reciprocated while in such plane, so as to more effectually perform the spiking operation when desired. When the bed has been sufliciently tamped on one side of a rail, the beam 13 may be lifted through the movement of the piston 12, whereby the plungers 18 may be raised above the horizontal plane of the rail, and the entire mechanism may be caused to move laterally through the operation of the gear 34 meshing with the rack 33. When the parts have been moved laterally the desired distance, the beam 13 may be dropped and the tampers set into operation.

Although the details of one particular embodiment of a tamping mechanism have been specifically set forth, yet it will be understood that any suitable changes or minor variations therefrom may be made without departing from the spirit and scope of the in- Vention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
