CHARLES HEATON, OF BAINBRIDGE, NEW YORK.

BLASTlNG-BARREL FOR EXTRACTING TREE-STUMP S.

SPECIFICATION forming part of Letters Patent No. 363,233, dated May 17,1887.

Application filed February 19, 1887. Serial No. 228,275. (No model.)

To aZZ whom it may concern:

Be it known that I, CHARLES HEATON, of Bainbridge,in the county of Ohenango and State of New York, have invented certain new and useful Improvements in Guns or Mechanical Appliances for Extracting Tree-Stumps; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being bad to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in guns or mechanical appliances for bursting tree-stumps; and it consists in, first, a gun provided with a screw-thread upon its external surface, so that it can be screwed directly into the stump, and which is provided with a spring-actuated firing-pin. or other'device for firing on the load; second, a gun provided with a screw-thread upon its surface, with a suitable opening through the gun, whereby the gun can be screwed by means of a bar into the stump; third, the arrangement and construction of parts, which will be more fullydescribed hereinafter, and set forth in the claim.

The object of my invention is to provide a gun or mechanical appliance whereby a charge of powder may be used for bursting the stump,

and'thus enabling it to. be readily extracted from the ground, whereby a great saving is effected in time, labor, and machinery.

Figure 1 represents a side elevation of a gun embodying my invention. Fig. 2 is a horizontal longitudinal sectiontaken at right angles to Fig. 1.

A represents the barrel of the gun, which is screw-threaded upon its outer surface for any desired distance, so that it can be screwed into a hole which is bored into the s'oundest part of the stump. This gun is preferably made tapering,as is here shown; but this form is not absolutely necessary. Through the center of thebody of the gun is made an opening, B,-through which a bar or rod, a, can be passed to act as a lever in forcing the gun into the hole bored in the stump. Formed upon one side of this central portion of the body is the eye 0, in which one end of the chain or wire b, which is fastened to a heavy block or log of wood, is secured. This chain or wire prevents the gun from being blown away to any great distance when the discharge takes place. The outer end of the body of the gun is made hollow, asshown in Fig. 2, and in this hollow end is placed the spring-actuated fir ing-bolt D, which when released, after having been drawn back, explodes a cartridge, F, which is placed in a suitable recess made to receive it in one end of the, opening B. This recess communicates, of course, with the barrel of the gun, so that when the cartridge is exploded it ignites a charge of powder which is placed in the barrel of thegun. When the firing-pin is drawn back into the position shown in Fig. 2, it is held in this position by means of a pin or rod, E, which is passed through a hole in the body just in frontof the pin. To the eye of this rod is fastened a cord or wire, (1, by means of which the rod is pulled out, so as to let the firing-bolt explode the cartridge.

A suitable amount of powder is first placed in the barrel and slightly wadded. The gun is then screwed in the hole in the stump, the cartridge inserted, the firing-bolt drawn back, and the rod E forced through so as to hold the firing-bolt in the position shown in Fig. 2. The wire, chain, or rod is then fastened to the eye a and to any heavy weight which will prevent' the gun from being blown away. The operator retires behind any convenient cover, pulls the wire or cord connected to the rod E, when the firing-bolt strikes the cartridge and the charge of powder in the barrel is exploded.

extracted, thereby effecting a great saving in time, labor, and machinery.

Where this device is to be used in blasting rock or coal, the screw-thread will be entirely done away with, and the gun will then be forced into the opening which is made to receive it. When the discharge of the powder takes place, the rock or coal will be broken. to pieces.

Having thus described my invention, I claim-1 The combination of a gun or mechanical ap- This charge of powder explodes the stump and blows it into pieces, so that they can be readily pliance for containing a charge of powder, In testimony whereofIafiix my signaturein 10 provided with a screw-thread upon its outer presence of two witnesses. surface, and having an opening,B, transversely through the body thereof, and an eye, a, for CHAS.
