IMPROVEMENT IN MAGHINES'FDR BORING WOOD.

TQ ALL WIIOM I'I MAY CONCERN: I
Be it known that I, GEoRGE DRYDEN, of Wrcester,in. the county of Worcester, and Statel of Massachusetts,`
have invent-ed certain nenv and useful Improvements in Boring-Machines; and I lo-hereby declare the' following -to be afull, dlear,- andexact description of the same, due reference being had to the accompanying drawings, making part of this speciiication,l in nhich- I u Figure 1 shows a front view of my invention.
Figure Zshews a part of the back, with the adjustable stop and its groove. d The same letters indicate the sarneparts4 where they occur.
Myiuyentionrelates to those boring-machines used for boring for mortises and similar purposes, and consists in pivoting the mechanism that drives the .augen to a plate -or frame sliding on the basent` the machine,
and operated by arack and pinion to adjust it for boring the different holes successively, and. also in arranging a central elevating-gear permanently in mesh, with a stationery rack attached to the standard,dwith, suchl form andfeon'structon of' partsas to make a convenientand Aeiiective boring-machine.
In the drawings, A is'the basepD, the standard, forked and .pivoted to the plate B, sliding on. the base,
A. The plate B is operated by a pinion on theshaft S, ivhich meshes into a rack on the under sideof'B. 'C C are the arches or Ways to adjust the machineto bore anydesired angle. O, the mandrel, with a socket at its lowersend?, P, to hold the auger, the other provided with a bevel-gear, L, by which it is drivenv and issupported in the frame B R, which slides on'the'standard D, and carries a cross-shaft, F, ivith crank at each end, .and .fr loose' spur-gear, H, in the middle, .over the mandrel, working into the rack E on the standard D, and a.
bevel-Gear G' to ive motion to the oue'n the mandrel. z is a. clutch, slidinv on the shaft F and drivin lr the C 9 i a ,o 5 l:
spur-gearl' whenslid up to it. m 'n is 'a boltd'and nut, .tosecure the standard.' in the position' desired byl fastening it to the-ways. Y *y In 2 is shown the back of the lower part of the standard D, and a groove, u, in which slides the'adjustable s'top T, situated below' the frame, and stopping it stops the auger fro'm cutting any deeper than desired,
and theoperator then sliding the clutelrz' into the gcarH, and continuing the izuotion of theishaft F, thevgear and rack elevate rthe frame R and withdraw the auger.
The` 'gear H, being over the centre of the auger, draivs straight up, without canting against.' one side, as is thecasc in the. common form oi" construction.
The-other partsmay beo' the usuali'orms, and it is therefore deemed unnecessary to describe them more A minutely here, and the operation is plain from the above. 4 l
I am aware thatI gear sliding in and out of a stationary rack havebeen used, and also that the rack has been grade movable; these I do not claim but What I claim, and desire to -securehy-Letters Patent,l is` s 1. The connecting ofjthe driving and' carrying-mechanism to a. sliding plate oriframemoving on the` base Y by means ot' a rack and pinion, for' the purpose of boring the holes of mortises successively, as above set forth. v
2. The cen-tml'elevatingfgean whenpermanently-in mesh with a stationary rack attached to a standard, andoperated by a. sliding clutch, substantially as set forthand described. g
GEORGE DRYDEN.
