KNOX TAYLOR, OF HIGH BRIDGE, NEW JERSEY, ASSIGNOR T0 TAYLOR-WHARTON IRON AND STEEL COMPANY, OF HIGH BRIDGE, NEW JERSEY, A CORPORATION OF NEW JERSEY.

TAMFING TOOL.

Application filed August 3, 1921.

To all whom t may concern:

Be it known that I, KNOX TAYLOR, a citi- Zen of the United States, residing at High Bridge, in the county of Hunterdon and State of New Jersey, have. invented certain new and useful Improvements in Tamping Tools, of. which the following is a specifica to provide a tamping tool whereof at least the wearing portion of the head shall be constructed of manganese steel, which is remarkable for its toughness, hardness and enduring qualities. In practicing the invention, the head, or its wearing or impact portion, may be integral with the remaining structure, or it may be detachable, or detachable and reversible. Moreover, it is otherwise so constructed that it may be readily cleared of any ballast materia-l which it may trap, and re-dressed, as by grinding, if necessary or desirable.

The nature, characteristic features` and scope of the invention, will more readily be understood from the following description and claims, reference being had to the accompanying drawing, forming a part thereof, 'wherein- Fig. 1 is a perspective view of the tamping tool embodyingmy invention.

Fig. 9 is an end view thereof; and- Fig. 10 is a similar view of the same redressed after service.

Referring to Figs. 1 and`2, a tamping tool is indicated, the head 5 of which is preferably constructed of manganese steel. The impact portion of the head is cupped or concaved, as at 6, to facilitate grinding, when necessary, but mainly to engage the ballast material. There are end slots 7 and laterally opening slots 8, which when present are useful in ejecting any ballast material which may stick in the cupped portion 6.

In the modification, Figs. 3 to 5, the impact or wearing portion of the head is cupped as at 9, the cupped area merging with a relatively deep slot 10 extending the length of the head and open at both ends. Aside from its utility in ejecting trapped ballast material, the full length slot 10 is useful to temporarily take care of metal peened from the surface, and it is furthe-r useful in that it simplifies redressing of the impact surfaces as by grinding or otherwise.

The head may be solid with the shaft, or it may be constructed with a detachable wearing or impact element 11, having an interlocking fit such as shown, for example at l2.

I may also, if desired, provide a reversible impact element such as, for example, shown in Fig. 7, which illustrates a .double member so constructed and arranged that when one face 13 is worn, it may be reversed to present the other face.

Figs. 8, 9, and 10 illustrate a tamping head having a full length slot 14 which eX- tends to within a comparatively short distance of the shaft, and is cupped as at 15. In service, the wing members or side walls 16, have a tendency to spread, as indicated in dotted lines in Fig. 10.

The head is then re-dressed, as by grinding, so as to insure uniformly straight outer walls. The effect of the spreading is to impart a flare 17 to the slot as clearly shown in Fig. 10 and this condition is manifestly useful in holding and advancing the ballast 2.
