UNITED STATES PATENT OFFICE.
HIRAM H. CHAPMAN, OF SOUTH ROUKVVOOD, MICHIGAN.
DRILLING- MACHINE.
SPEOIFIOATION forming part of Letters Patent No. 248,913, dated. November 1, 1881.
Application filed June 17, [881.
To all whom it may concern:
Be it known that I, HIRAM H. CHAPMAN, of South Bockwood, in the county of Monroe, and State of Michigan, have invented an Improvement in Drilling-Machines, of which the following is a specification.
The nature of this invention relates to certain new and useful improvements in the construction of drilling-machines of that class wherein the drill is advanced to the work; and the invention consists in the peculiar construction, arrangement, and combinations of the parts, all as more fully hereinafter set forth.
In the accompanying drawing, which form a part of this specification, and in'which my invention is shown in perspective, A represents a suitable vertical frame which supports and carries the operating parts of the device. B is a gate adjustably secured on one side of this frame, and is capable of a vertical play thereon. To the upper end of this gate B is secured in any desired manner one end of the spring 0, the opposite end of which is secured to the top girt of the frame A, the function of the spring being to retain the gate B in its elevated position when not in operation. To the lower portion of the gate B are secured outwardly-prqjecting arms or studs, a, each of which engages with a proper strap or rod, 1), the opposite end of which strap is pivotally secured to the treadle-lever D, which is pivoted to the frame A, and by placing the foot upon this lever D the gate can be drawn down so as to bring the drill in contact with the work, as hereinafter described.
Near the center of the gate B is journaled (No model.)
in proper boxes, 0, the shaft E, provided upon its outer end with a crank-handle, F, and upon its inner end with a crowned gear-wheel, G, which engages with a bevel-pinion, H, near the lower end of the vertical shaft I, which is journaled in proper hearings (2. Upon the face of the gate and tozthe lower end of this shaft I is secured any proper drill-stock, J, which carries the drill K, which is rotated through the connections herein described by means of the crank-handle F.
A series of holes, 0, is made in the lower portions of the frame A, which receive pins f, upon which rests a table-board, 0, so that thicker or thinner work may be presented to the action of. the drill.
I am aware that it is not new to arrange the auger of a wood-boring machine in a vertically-sliding holder which is raised by a spring and depressed by a foot-lever, and therefore I do not broadly claim such invention.
What I claim as my invention is In a drilling-machine, and in combination with the side bars of the frame A, the sash B, provided with irons B, by which it is kept close against the side bars when moving up and down, the spring (1, fastened to the top bar of the frame, the flexible connection 0', between the spring and the sash, the treadle D, rods I), connecting the sash at both sides to the treadle, the shafts E I, gears G El, and
the drill-stock J, substantially as specified. HIRAM H. CHAPMAN. Witnesses:
