WILLIAM HENRY RAINS, OF HARTFORD, ARKANSAS.

MINING-MACHINE.

Specification of Letters Patent.

Patented July 11, 1911.

Application filed October 18, 1910. Serial No. 587,750.

To all whom it may concern:

Be it known that I, WILLIAM HENRY RAINS, a citizen of the United States of America, residing at Hartford, in the county of Sebastian and State of Arkansas, have invented new and useful Improvements in Mining-Machines, of which the following is a specification.

This invention relates to mining machines, and it has for its object to produce a simple and thoroughly eflicient machine formining coal from the top of the vein, next to the roof, although the range of utility of the machine is not to be regarded as limited in this respect.

A further object of the invention is to produce a machine of the character described which shall possess superior advantages in point of simplicity, durability and general efiiciency.

With these and other ends in view which will readily appear as the nature of the invention is better understood, the same con sists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims. In the accompanying drawing has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claims may be resorted to when desired.

In the drawing,Figure 1 is a perspective view of a mining machine constructed in accordance with the invention. Fig. 2 is a vertical sectional view taken on the plane indicated by the line 22 in Fig. 1.

Corresponding parts in both figures of the drawing are denoted by like characters of reference.

The base of the improved machine includes a longitudinal bar or member 1 and a transverse bar or member 2, the latter being disposed crosswise adjacent to one end of the former, and said bar or member being pivotally connected with the cross bar by a pin 3 having a retaining nut 4s. The longitudinal bar 1 provided with an upwardly extending arm 5 adjacent to the cross bar 2, and said cross bar is provided with an arch 6 having a slot 7 for the passage of a bolt 8 extending from the arm 5, said bolt being equipped with a tightening nut 9. The ends of the cross bar 2 and the end of the longitudinal bar which is distant from said cross bar are provided with ground engaging spurs 10.

The longitudinal bar 1 is provided intermediate its ends with a sleeve 11 having an upwardly extending lug 12 with which a tubular socket member 13 is hingedly connected by means of a pin 14. Springs 15 connect the socket member 13 with the bar 1 at opposite sides of the hinge, said springs serving to maintain the socket member normally in an upright position from which, however, it may be tilted in either direction. It is evident that when the socket member is thus tilted, one of the springs will be placed under tension and that when the strain required to tilt the socket member is removed, the said socket member will automatically assume an upright position.

Telescoping in the socket member 13 is an extension rod which is composed of two hingedly connected

members

16 and 16, and which may be retained at various elevations by a set screw 17. Swiveled upon the upper end member 16 of the extension rod by means of a pin or screw 18 is a T-head l9. Extending through the T-head is a tool holder 21 which may be secured by a set collar 22 and which is socketed at one end for the reception of a drilling tool 23 which may likewise be secured by a set screw 24. The handle end 25 of the tool holder is made sufficiently heavy to counterbalance the load which may thus be conveniently manipulated.

In the operation of this device, the base frame rests upon the ground where it is securely held by the ground engaging spurs 10. The bar 1 may be tilted to various positions with reference to the cross bar 2 and may be secured at any desired adjustment by the tightening nut 9. The socket member 18 may thus be disposed at various inclinations. The elevation of the tool may be regulated by adjusting the

extension rod

16, 16 in the socket member 13, and the tool holder may be rotated in the T-head, which latter is swiveled upon the upper member 16 of the extension rod, thus enabling the tool to be presented in any desired direction. The device is operated by rocking the hingedly mounted spring supported socket member 13, thus enabling effective blows to be struck.

Having thus described the invention, what is claimed as new, is

1. In a device of the character described, a base including a cross bar, a longitudinal bar connected with said cross bar intermediate the ends of the latter, and means for securing the longitudinal bar at various points of oscillation, a socket member hingedly connected with the longitudinal bar, and a tool carrying extension rod in said socket member.

2. In a device of the character described, a base comprising a cross bar and a rocking member adjustably connected therewith, a socket member hingedly connected with the rocking member, a tool carrying extension rod telescoping in the socket member, means for securing the extension rod at various adjustments, and springs connecting the socket member with the rocking member.

3. In a device of the character described, a base comprising a rocking member, a socket member hingedly connected therewith, springs connecting the socket member with the rocking member, an extension' rod telescoping in the socket member and comprising two hingedly connected members, a T-head swiveled upon the extension rod, and a tool holder extending through and revoluble in the T-head.

4. In a device of the character described, a base comprising a rocking member, a socket member hingedly connected therewith, an extension member telescoping in the socket member and comprising two hingedly connected members, a T-head swiveled upon the extension member, means for securing the latter in adjusted position, and a tool holder extending through and revoluble in the T-head.

5. In a device of the character described, a base comprising a rocking member, a socket member hingedly connected therewith, supporting springs connecting the socket member with the rocking member, an extension member telescoping in the socket member, means for securing the extension member at various adjustments, a 'T-head swiveled upon the extension member, and a tool holder extending through and revoluble in the T-head.

6. In a device of the character described, a base comprising a rocking member, means for securing said rocking member at various points of oscillation, a socket member hingedly connected with the rocking member, springs connecting the socket member with the rocking member, an extension membertelescoping in the socket member, a'

T-head swiveled upon the extension member, means for securing the latter in adjusted position, and a tool holder extending through and revoluble in the T-head.

In testimony whereof I afiix my signature in presence of two witnesses.
