Description
NITED STTEs IMPROVEMENT IN TAMPING APPARATUS.
Specification forming part of Letters P To all whom Aif may concern:
Beitkuown that I, DANIEL CORGAN, of Sugar Notch, in the county of Luzerne an d State of Pennsylvania, have invented a new and useful Improvement in Tainping-Iniector5 and l do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had t0 the accompanying drawing forming part of this specification.
This invention relates to a new a-nd useful improvement in tamping charges in the process of blasting rocks or coal 5 and it consists in atamping-injector, constructed and opera-ting as hereinafter described.
In the acmnnpanyu'ng drawing, Figure l represents a longitudinal section of the cylinder or barrel with the handle or rod connected therewith. Fig. 2 is a cross-section taken on the line a' :r otFig. l.. Fig. 3 is a cross-section taken on the line y y of Fig. I.
S mil ar letters of referen ce indicate correspond* ingI parts.
A the cylinder or barrel, in which. the tampin material is placed. I3 is the rod, the end of which is made to fit the inside of the barrel, so that it may act as a plunger therein for forcing out the tampin material into the drill-hole, where powder or other explosive substance has been placed. The cylinder is bent slightly inward at atout No. 116,565, dated July 4, 1371.
the lower end, so as to prevent it from being d 'awn olf the plunger, whose head or upper end is made larger than its body or remaining portion. (l is the handle. I) is a stop or key which passes through the handle, but is removable by means of the screw E. This stop prevents t-he plunger from passing entirely through the barrel. The diameter of the barrel A is slightly greater than that of the drill-hole. rlhe end of the barrel is placed so as to iuclose the drill-hole, and the tampiug material is forced into the hole and pressed by the plunger so that it will remain in a hole drilled upward into a seam of coal, which is worked from the bottom, as is frequently the casein mining anthracite coal. Then the tamping material has been pressed into the hole the tamping-bar is applied, by which the material is rendered as compact as may be desired.
By the use of the tampiilg-injeetor much valuable time is saved, and the risk to life and limb from this dangerous occupation is greatly lesscned.
Having thus described my invention, I claim as new and desire to secure by Letters 'Patent- A tamping-injector for use-'in blasting constructed, substantially as shown and described, so as to admit of the operation specified.
fitnessesz DANIEL CORGAN.
