I Application filed February 17, 1886. v Serial No. 192,220. (No model.) 1
The object ofv our Invention is to provide a device for breaking down coal, whereby they use of powder or other dangerous explosives heretofore used for that purpose is entirely' done away with, thus lessening'the danger and greatly improving the condition of the coal delivered from the mine. J
' Our invention consists in the construction and arrangement of parts, as will be hereinafter fully described and claimed.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in both figures.
Figure l is a longitudinal sectional view of our improved coal wedge and breaker. Fig. 2 is an end View of the instrument, the collar and washer being removed and the shaft being in section.
A represents a cylinder made up of sections a a, said sections being semi-cylindrical. in cross-section, and each section being formed with a tapering groove,- as b b, said grooves being so arranged and proportioned thatwhen the sections a a are brought together, as best shown in Fig. 2, there will be "formed a rectangular recess, c, within which there is fitted and arranged a wedge-shapedblock, B. This wedge-shaped block B is formed with a central threaded socket, 02, within which there is fitted a threaded end, 0, of a shaft, D. In use the end of the cylinder A is inserted within the hole drilled in the coal until a washer, E, strikes against the face of the coal.
Just beyond the washer E there is arranged a collar, F, which is secured to the shaft D by a set-screw, f, and it will readily be under-.
-.stood that by turning the shaft D the wedge B will be drawn within the recess 0, and as it is so drawn in the sections a a of the cylinder A will be expanded and the coal willbe broken down, it being understood that prior to the introduction of the cylinder the coal has been undercut and sheared. The
washer E, bearing against the face of the coal, andbeing in turn borne upon by the collar), prevents the shaft D from being drawn 111- .Ward when turned within the threaded socket of the Wedge B.
Having thus fully described our invention,
what we claim as new, and desire to secure by Letters Patent, is
As an improved article of manufacture, a
wedge for breaking down coal, consistingin the cylinder A, formed of the two semi-cylindrical independent sections ct a, each hav- JAS, o. WATsoN: CONRAD A. sIrn.
