G. S. DERR.
WOOD-BORING MACHINE. No,184,06 5 Patented I-TovLfL1876- I W U l NITED STATES PATENT OFFICE,
GEORGE S. DER-R, OF SOUTH BEND, INDIANA.
IMPROV EMENT IN WOOD-BORING MACHINES.
Specification forming part of Letters Patent No. 184,065, dated November 7, 1876; application filed October 26,1876.
To all whom it may concern.-
Be it known that I, GEORGE S. DERR, of the city of South Bend, in the county of St. Joseph and State of Indiana, have invented a new and useful Imprm'ement in Boring-Machines, which improvement is fully set forth in the following specification, reference being had to the accompanying drawing.
The figure in the drawings represents a side elevation of my machine.
The object of my invention isto construct a machine by means of which I am enabled to bore at any angle or at any depth; and the nature thereof consists in the combination of the devices employed, as more fully hereinafter set forth.
A A are the supports; B B, the reversible fastenings; O O, the fasteningscrews; D D, trunnions connected with gear-support 5 E, the driving-shaft; F F, the driving-gear; G, lifting-pinion; H, the auger-shaft; K, the angle-indicator, provided with a threaded socket. The machine is fastened to the material to be bored (represented in the drawing by l) by passing .the screws 0 0 through the reversible fastenings B B, into said lnateriai. A bit of the requisite size is screwed into the socket of the auger-shaft. The auger or bit is placed against the material to be bored at the angle required. The crank is then turned, and the hole bored. To withdraw the auger or bit, the driving-gear is thrown out of gear, which brings the lifting-pinion G into gear with a.
rack upon the auger-shaft. The motion of the crank is reversed, and the bit or auger is withdrawn from the hole. The auger-shaft is caused to turn by a key placed in the driving-gear and fitting in a slot in the shaft, permitting said shaft to slide upon it.
To bore a hole deeper than can be bored by the auger'shaft represented in the present ap- GEORGE S. DEER. Witnesses:
