Description
l UNITED .STATES PATENT OFFICE.
AMOS LEONARD, OF SULLIVAN, OHIO.
IMPROVEMENT |N BORING-MACHINES.
Specification forming part of Letters lPatent No. 33,324, dated September 17, 1861.
fo au whom', it may concern.-
Be it known that I, AMOS LEONARD, of Sullivan, in the county of Ashland and State of Ohio, have invented new and useful Improve the accompanying drawings, making part of,
this specification, in which* Figure l is a perspective View. side view, and Fig. 3 is a top view.
Like letters refer to like parts.
The nature of my invention relates to the means employed for propelling the auger while boring the hole, and the devices for withdrawingit from the timber when lthe hole is bored.
A represents the base or foundation of the machine. This consists of abard-wood plank, say two feet long, one foot wide, and two inches thick. At one end a piece is cut out about six inches in width and about eight inches in length, as seen at B. Upon each side of the opening thus formed is inserted a post C, which posts form the guides to the sliding frame D. The sliding frame D contains the gearing by which the auger is propelled.
E is the shaft that receives the shank of the auger. The upper end of this shaft carries a bevel-wheel F, which gears into the bevelwheel G, which is of greater diameter than the wheel F for the purpose of increasing the speed of the shaft E. The shaft that carries the wheel G is horizontal, and contains, besides the wheel G, two pinions II and I. The pinionHgears into the main or driving wheel J, whose shaft is also horizontal. The driv Fig. 2 is a l ing-wheel J has a diameter of from eight to ten inches, while the pinion H has not more than two or three inches diameter. A quarter-revolution, therefore, of the wheel J will turn the auger-shaft E a number of times around.
The driving-wheel J is propelled by means of the lever K, whose fulcrum is upon the shaft of the wheel J. Two pawls L and L', which are held in place by springs, serve to give motion to the wheel J whenever the lever K is moved up or down. Therefore every stroke of the lever in the direction of the arrow will give the auger a number of revolutions, and repeated strokes will soon cause it to penetrate the desired dept-h into the timber.
M is a rack-lever. It is secured to the base at the lower end by means of a screw or bolt. The upper end is free. That side next to the pinion I is furnished with teeth M', which gear into the pinion I by pressing upon the upper end of the lever M, which brings the teeth M into gear with the pinion I. The pawl L is double-that is, it extends upward through the lever K, as seen at N. Now in order to raise the sliding frame D, and with it the auger, the pawl N is pressed against the wheel J while thevlever K is depressed, when by raising the lever the wheel J ls rotated backward, and the pinion I being acted upon by the rack M the whole sliding frame D, with the gears and auger, is raised to the height desired.
What I claim as my improvement, and desire to secure by Letters Patent, is-
v The special arrangement of the lever K,
sliding frame D, rack-lever M, and intermediate gear-wheels, operating substantially as and for the purpose specified, by which means the auger is caused to bore the mortise and is also raised up out of the hole after being bored.
AMOS LEONARD.
