TO WHOM IT MAY CONCERN;

Be it known that I, JONATHAN NULL, of Quincy,in the county of vIlrantlyilin, a'nd State of Pennsylvania, have invented a. new and useful VImprovelznent in Machines for BoringlPostsf'and I do hereby declare that the following is a.A full and exact description thereof, reference being had tothe accompanying drawings, and to the letters of reference ma-rked'ithereon. 'I v My invention consistsin a novel arrangement'of frames and other devices for holding` a. post for boring, and also in moving they post conveniently iu relation to the anger. In the accompanying drawings- Figure-1 is a top view ofmy machine. v i

Figure 2 is af side view of the saine; and

. Figure 3 is an end view. A

In the construction of my machine, a, suitable frame, A, is made, and the auger B arranged thereon, as seen inV figs. 1 and 3. The augerlrnay have a'crank, C, foiworking byy hand, and also a pulley, D, for a hand, and the use of power. It is also providedwith a balance-wheel, E. Upon the mainframe A is arranged another frame, F, which has a. lateral motion, by means of a shaft, G, carrying two cog-whecls H, working in ratchet-bars, and u. crank, I. This shaft is also` provided with a half-wheel, K, and a weight, L, which serves to press the frame F toward the auger while boring,'and thusv give proper feed. A third frame, M, is`placed upon the frame F, and' provided with a sliding motion, to carry the post forward from hole to hole in boring. This frame may be fixed by means of a set-spring or hook, N, figfl, which catches in the holes S, in frame M.

- The post is held in place uponthe frame M bymeansof set-screws O, which are worked by cranks Ou The.

frames are held together by-suitable guide-rods I and hooks R.

I do not confine my invention to the precise `details above described, but propose to v'arythe same as prac-- tical experience demands, so long as the machine issubstantially the same.`

I am aware that post-boring'niachines have been constructed, and therefore limit my claims to the abovedescribed improvements.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent of the United States, isv The frame F, moved by the shaft G-,cogwheels H, crank I, wheel K, and weight L, and the movable frame .M, controlled bythe spring N, when constructed and arranged to operate substantially in lthe manner and for the purposes as set forth. Y

JONATHAN NULL.
