TAMPER.

r To all lwhom t may concern:

' effective 'in tamping Be it known that I, CoR\viLL J. AoKsoN, a citizen of the United States, residing at the city and county of Kalamazoo, State of Michigan, have invented certain new and of which useful Improvements in Tampers, the following is a specification.

This invention relates to improvements in tampers.

My improvements are especially designed by me 'for embodiment in tie tampers and the embodiment illustrated is especially adapted for that purpose. My improvements are, however, readily adapted for and of advantage for use in other relations.

The main objects of this invention are:

First, to provide an improved tamper which is of large capacity in that it enables the perfomance of a large amount of work with comparatively little effort on the part of the user.

Second, to provide which is very durable in use.`

Third, to provide an improved tamper for use in tamping ties the earth under the ties providing a bed which is not likely to settle or have untamped portions in which the material is easily loosened by means of water or the like.

Fourth, to provide an improved motor driven tamper in which the parts are compact in structure and arrangement and not likely to become inoperative or get out of repair in use.

Further objects, and objects relating to structural details, will definitely appear from the detailed descriptionvto follow.

I accomplish the objects of my invention by thedevices and means described in the following specification. The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing forming a part of this specification, in which.:

sponding to line 4 4 .of Fig. IfI, showing the arrangement of the unbalancing weight on the shaft.

FignV is a plan view of the tamping bar, a portion-being broken away;

Fig. VI is a vertical section through-the tamping bar or tool holder on a line corre-- sponding to line 6 6 of Fig. III.

In the drawing similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referringto the drawing: i

I provide a casing 1 on which the motor designated Generally by the numeral, is mounted. 'Flic armature 3 of the motor is mounted upon the shaft 4 having bearings 5 in the ends of the casing. This shaft is provided with a pair of unbalancing weights 6 disposed at the ends thereof and near its bearings. The casing is preferably cylindrical in form, as illustrated. On its under side, the casing is provided with a tangentially disposed tool or tamping bar holder 7 having a socket 8 for the tamping bar 9. The tool holder is disposed centrally' of the casing.

The tool or tamping bar Iis provided with so l opposed notches or recesses 10 engaged by the staple-like retainer 11 passed through the holder and held'therein by means of the cotter pin 12; This retains .the tamping bar for limited, reciprocating movement within the holder so that` vibrations ,of the casing are imparted thereto as blows, the casing constituting an impact member for the tool or tamping bar.

The casing is provided with a handle 13 havin spring portions 14 therein, the handle being of bail-like form, the arms 15 of the handle being connected to the ends of the casing at 16. The handle is provided with a second gri or hand-piece 17.

With the arts thus arranged, the rotation of the s aft 4 vibrates the casing and this vibration is imparted to the tool or tamiping `bar in the holder providing 'a highly efiicient implement for the tamping of ties and the like, the tamper enabling the performance of av large amount of work with little effort on the part of the operator and the tamping being effected in a superior manner, that is, the earth may be rapidly f ll have illustrated and described my improvements in two embodiments which l consider very satisfactory. l have not attempted to illustrate or describe various other modifications or embodiments which l' I contemplate as l believe the disclosure made l claim as new and desire to secure by liet.

ters Patent, is:

l. ln a structure of the class described, the combination of a casing having a tan-- gentiallydisposed tool holder on its under side, a shaft provided with bearings in the ends of said casing and having unbalancing weights at its ends, a driving motor for said shaft disposed centrally within said casing between. said unbalancing weights, a handle comprising spring members connected to the ends of said casing, and a tool having a limited reciprocating movement in said holder.

2. lin a structure of the class described, the combination of a casing, a shaft provided with bearings in the ends of said casing and having unbalancing weights at its ends, a driving motor for said shaft disposed centrally within said casing` between said unbalancing weights, a handle comprisingv spring members connected to the ends of said casing, and a tool mounted on the under side of said casing and centrally thereof.

3. in a structure of the class described, the combination of a casing having a tangentially dispesed tool holder on its under side, .a shaft having an unbalancing member thereon provided with bearings in the ends of said casing, a driving means for said shaft, a resilient handle connected to the ends of said casing, and a tool having a limited reciprocating movement in said holder. v

1i. ln a structure of the class described, the combination of a casing, a shaft having an unbalancing member thereon provided with bearings on said casing, a driving means for said shaft, a resilient handle connected to the ends of said casing, and a tool mounted on said casing for limited reciprocating movement whereby it receives the impact of the casing.

5. In a tamper, the combination of a casing, a shaft provided with bearings in the ends of said casing and having unbalancing isaiasi.

weights at its ends, a driving motor for said shaft disposed centrally within said casing between said unbalancing weights, a handle comprising spring members connected to the ends of said casing, and a tamping bar tangentially mounted on said casing.

6. in a tamper, the combination of a shaft having an unbalancing member thereon, a

driving motor therefor, a casing, a tool holder on said casing, a tool having a limited reciprocating movement in said tool holder whereby it receives the impact of the casing, and a handle having resilient connection to said casing.

7. in a tamper, the combination of a shaft having an unbalancing member thereon, a driving motor therefor, a casing, a tool holder on said casing, a tamping bar having a limited reciprocating movement in said tool holder whereby it receives the impact of the casing, and a resilient handle.

8. in a tamper, the combination of a shaft having an unbalancing member thereon, a driving means therefor, a casing, a tamping bar mounted on said casing for limited movement thereon and to receive the impact of the vibrations thereof, anda handle having a resilient connection to said casing.

9. fn a tamper, the combination of a shaft having an unbalancing member thereon, a driving means therefor, a casing, a tamp ing bar mounted on said casing for limited movement thereon and to receive lthe impact of the vibrations thereof. l
