2 v corms-i tail way C (Fig. 5) in which fits a guide bar M along which the cylinder may be longitudinally adjusted and to which it may be fixed by a setscpew M. Ihe guide bar is connectedto a sleeve N, sliding on the bar G, by a swivel joint'oi common construction, shown in Figs. 5 and-6, whereby the cylinder may be inclined in its plane of movement along the rod G and thus the ballast beneath the rails be readily tamped from the inside or outside of the rail, Then the piston is raised to the upper end of its path, the tamping tool is above the plane of the ties, and by then rocking the cylinder upon the rod G it will be thrown above the plane of the rails and may be carried from one side of the rail When the tool is thus raised and the middle of the toggle-bar is also raised, the whole apparatus may be pushed along the rails to tamping position alongside a difi'erent tie.

In use, two tampers are ordinarily arranged as indicated in Fig. 1, one attendant for each holding down the corresponding toggle-bar and controlling the tamping while a third man moves both cylinders along the rods G. One man readily puts'a tamper in place and removes it from the track, and the three easily lift on and oh the track the light motor car, not shown. I

Fig. 7 hows a form -in which vertical brackets O, 0' support the .rodG which in this case has free ends extending out from the rails approximately to the ends of the ties. In this form the devices tamp between and beneath the rails as before, but they must be transferred to the outer ends or" the rod G for tamping outside the rails. In this figure, the plate 0, corresponding to the plate H of the primary form, is shown as plane, and especially adapted for use over a heavy fish plate P and its nuts or bolt ,heads Q. Such a plate may be quickly substituted for the plate H of the other form, when desired, if the pintle be withdrawn as beforesuggested.

Cit

In order that the vibration of the rod G may be lessened when tamping near the middle of the tie, I in some instances support it at points over the rails, respectively, by extensible and readily removable struts S, Fig. 2, of any convenient construction.

Many changes may be made without passing the proper limits of my invention and I do not, therefore, wish to limit my claims to the'spccific embodiment shown.

What I claim is:

1. In tamping apparatus, the combination with a fluid pressure cylinder, a piston working'in the cylinder and provided with a noncylindrical piston rod, a tamping tool car .ried by the piston rod, and means for supporting the cylinder above the plane of the tie to e operated upon. 2. In a tie tamping apparatus, the combination with a transverse bar, of supports for said bar adapted to rest directly upon the rails, means for clamping the supports to the rails, and a fluid pressure tainping device slidably mounted upon said bar.

3. Intie tainping apparatus, the combine;- tion with a transverse bar of a length materially greater than the width of the track, brackets dapted to be clamped to the rails to support, respectively, the outer ends of the bar, and fluid pressure tamping devices slidably mo'unted upon said bar.

s. In a tainping apparatus, the COlllbllltl,

tion with a transverse bar, of means for se- U curin the bar to the rails, a fluid pressure cylin er mounted to slide freely along said bar and to swing freely in planes parallel thereto, a'piston working in said cylinder, and a tamping tool carried. by said iston; whereby ballast may be tainped ob iquely beneath the rail.

5. In a tamping ap aratus, the combination with atransverse ar, of means for rigidly supporting the same above the rails, means for ri 'idly clamping the supports to the rails, a cydinder-supporting block mounted to slide along the bar and to swing trans- -versely thereon, and a tool-carrying fluid pressure cylinder mounted upon the block to swing in planes parallel to the bar. 6. In a tamping apparatus, the combination with a transverse bar above the rails when in operative position, means for rigidly supporting the bar from the rails, a cylindersupporting block mounted to slide along the bar and to rotate about the same, fluidpressure cylinder mounted upon the bloclr to swing in planes parallel to the bar, and means for adjusting the cylinder, in a direction parallel to its axis, upon the block.

7. In tie 'tamping apparatus, the combination with a transverse bar, of means for rigidly supporting the same fromv the rails, of a tool-carrying iluid-prcssurc cylinder mounted to slide freely upon the bar and to swing freely in planes transverse thereto and parallel thereto. v

8. In a tie taniping apparatus, the combination with a transverse bar, of means for rigidly supporting said bar from the rails, a tool carrying, fluid pressure cylinder mounted -transverse to the bar to slide thereon and to slide in the direction oi its own axis and also to swing in planes transverse to the bar and parallel thereto, respectively, and means for at will locking the bar in any position to which it may be adjusted by sliding in the direction of its axis.

whereby the apparatus when-leftby the operator is always free to lee-thrown aside by a train.

10. In tie tainping apparatus, the combination wilh a suitable support, of tamping deviees mounted upen said support, two clamps for rigidly securing the support to the rails, respectively, and'a toggle-bar free to be flexed by lateral pressure, and adapted to be interposed between the clamps and to force both into engagement.

11. In tie tanlping apparatus, the combination with a suitable support, of tamping devices mounted .upon said suppert, two clamps for securing the support to the rails, a toggle-bar adapted to be interposed between the: clamps and to force both to en-' gage the rails,

means for holding the ends of the toggle-bar at. the same distanee from the tops of the rails, and a leveling device attarhed to the toggle-bar:

12. In a tie taniping apparatus, the com-' clamps for securing the support to the rails, respectively. a toggle-bar adapted to be interposed between the two l-lamps and to force them into engagement, and a spring arranged to resist straightening ot the toggle bar.

In testimon whereof I afiix my signature in presence ov two witnesses.
