Application September 24, 1943, Serial No. 503,691
1 Claim.
This invention relates to atool for use in cribbing or digging While being adapted for operation by an air hammer tamping gun to overcome the usual digging or manual picking.
It is further aimed to provide a tool that is especially adapted for loosening dirt or stone ballast between railway ties or to loosen compound in compound crossings or station platforms.
The more specific objects and advantages will become apparent from a consideration of the description following taken in connection with accompanying drawing illustrating an operative embodiment.
In said drawing- Figure 1 is a front elevation of the improved tool;
Figure 2 is a side elevation thereof; and
YFigure 3 is a horizontal sectional view taken on the line 3-3 of Figure 2.
Referring specically to the drawing wherein like reference characters designate like or similar parts, the tool consists of a horizontal crossbar IE) of suitable steel to which are welded as at II a pair of teeth or points I2. More than two of these points may be provided if desired, and it is to be noted that they are tapered approximately throughout their length both in front elevation and in side elevation to reduce their chances of sticking in the ground or material being picked.
Rising centrally from the crossbar IIJ is a shank I3 which is forged integral therewith or welded thereto as at I4, and which at the upper end terminates in an attaching shank I5, suitably polygonal in cross section, for instance, hexagonal so as to fit the socket of the air hammer or tamping gun.
The points I2 are preferably made of alloy steel. In use of the tool, it is fastened by the ends of the attaching portion I5 in an air hammer or a tamping gun so as to be vibrated thereby and forced into the ground, to loosen dirt, stone ballast, compound or any other material, and thereby overcoming the laborious hand method of picking now prevalent. The particular tapering of the points I2 minimizes the danger of the points sticking in the ground or other material.
Various changes may be resorted to provided they fall within the spirit and scope of the invention.
I claim as my invention:
A tool of the class described having a shank, means thereon at one end for attachment to an air hammer or tamping gun, a crossbar at the other end of the shank, and points abutting opposite ends of the cross bar extending from the crossbar in outwardly spaced relation and in the opposite direction to said shank, said shank and points being welded to the crossbar, said points being tapered approximately throughout their length, said shank, crossbar and points being of steel.
HENRY G. DORAN.
