JASPER NUTEN RICKLES, OF ALTOONA, ALABAMA.

COAL-DRILLING MACHINE.

Specification of Letters Patent.

Patented Jan. 28, 1908.

Application filed August 3, 1906. Serial No. 329076.

a citizen of the United States, residing at Altoona, in the county of Etowah and State of Alabama, have invented a new and useful Coal-Drilling Machine, of which the following is a specification.

This invention relates articularly to means for drilling coal and. ike substances, but is not necessarily limited to this use.

In Patent No. 845,898, dated March 5, 1907, there is disclosed a manually-operated drilling machine having decidedly advantageous features, but it has been found that under certain conditions, the body of the machine has a tendency to twist or turn, instead of effecting the rotation of the drill.

One of the principal objects is to provide a novel and simple structure that will support the drilling mechanism and eliminate all liability of the said body turning, said struc ture being adjustable to different heights in order that the drilling mechanism will be properly positioned to the seams of coal or other material to be drilled.

Another and important object is to provide a structure wherein the presser head is adjustable in order that the same can be placed in the position considered most desirable by the operator.

An embodiment of the invention, that is at presen tconsidered the preferable one, is illustrated. in the accompanying drawings, wherelIlI Figure 1 is a view partly in section and partly in elevation of said mechanism. Fig. 2 is a horizontal sectional view through a rear portion of the same. Fig. 3 is a sectional view on the line 33 of Fig. 2. Fig. 4 is a detail perspective view of the lower portion of the supporting standard.

Similar reference numerals designate corresponding parts in all the figures of the draw ings.

In the embodiment, a support is employed that is in the form of a standard. This standard consists of a plurality of telescoped sections. An intermediate tubular section 5 has slidably mounted in its upper end a rod section 6, and in its lower end another tubular section 7. These various sections are arranged to be held against relative movement by set screws 8. The upper rod section 6 is of small enough diameter to enter the lower- II1OSJD section 7, and it will be clear that the bodiment, has outstanding pin support or standard can thus be expanded and contracted. The lower end of the lowermost section7 is provided with a cross bar 9, constituting a foot-piece, which is provided with terminal spurs 10. The upper end of the uppermost section has a yoke 11.

The drilling mechanism is substantially the same as that set forth in the patent to which reference has been made, and therefore need not be specifically described. fice it to state that a stock 12 is employed having a tool holder 13, journaled in one end, said tool holder being operated by handle cranks 14 through the medium of gearing 15 that is journaled on the stock. The rear portion of the stock 12, in the present emt es .16 that are journaled in the yoke 11, and thus the Sufdrilling mechanism is pivotally mounted on I opposite sides of the standard, and presses against the head 19, at the same time rotating the handle crank. It will thus be seen that the body of the drilling mechanism is securely held against rotation, and is supported by the holding means. At the same time, the cross bar 9, with the spurs 10, constitutes a bearing on Which the standard swings, so that the feed of the tool is secured. The adjustment of the presser head 19 is important, in that it permits the operator to position said presser head in the most convenient relation to the other parts.

From the foregoing, it is thought that the construction, operation, and many advantages of the herein described invention Will be apparent to those skilled in the art, without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing anyof the advantages of the invention.

Having thus fully described my invention,

what I claim as new, and, desire to secure by Letters Patent, is

1. In vmechanism of the character set forth, the combination with a supporting standard, of drilling mechanism mounted on the upper portion of the standard, a foot bar having an intermediate portion secured to the standard and constituting a support on which the standard swings, and depending spurs carried bythe foot bar and located on opposite sides of the standard.

2. In mechanism of the character set forth, the combination with a supporting standard comprising slidably telescoped sections, of means for holding the sections against relative movement, a cross bar car ried by the lower end of the lowermost section and having terminal depending spurs,

and manually actuated drilling mechanism pivotally mounted on the upper end of the uppermost section.

3. In mechanism of the character set forth, the combination with a swinging support, of a stock pivoted between its ends upon the upper end of the swinging support, a tool holder rotatably mounted on one end of the stock, driving means for the tool holder journaled on the stock between the said tool holder and the support, and a presser head mounted on the stock and located on the opposite side of the support to the tool holder and driving means.

4.1In mechanism of the character set forth, the combination with a swinging standard, of a stock pivoted between its ends upon the upper end of the swinging standard, a tool holder rotatably mounted on one end of the stock, driving means for the tool holder journaled on the stock between the said tool holder and the support, and a presser head mounted on the stock and located on the opposite side of the support one end of the stock, gearing journaled' on the stock for operating the tool holder, and a presser head slidably connected to the stock and disposed on the opposite side of the same to the gearing.

In testimony, that I claim the foregoing as my own, I have hereto afIiXed my signature in the presence of two witnesses.
