PROVISIONAL SPECIFICATION.
Improvements in Hand Power Boring or Drilling Machines.
I, JOSEPH HARDMAN, of Greenbank Yard, Victoria Street, Preston, in the
County of Lancaster, Wheelwright and Builder, do hereby declare the nature of
this invention to be as follows
--
This invention has for its object to provide a hand power boring or drilling
machine of convenient form for use by wheelwrights blacksmiths and the like and
with a handy means for altering the speed gear of such a machine to suit the
various sizes of holes to be bored or drilled.
In carrying out my invention I employ two horizontally disposed shafts arranged
parallel to each other and mounted in bearings or plummer blocks secured to the
upper side of a suitable framing or stand. On one end of one of the shafts is fixed
a handle and a fly wheel the said shaft carrying between its two bearings a
toothed wheel which gears into one or other of two or more pinions of varying
diameters on the second shaft. The second shaft at one end is in the form of a
chuck for holding the boring bits or drills and at a lower level than the axes of
the shafts is a horizontal table movable vertically by means of screw or worm
gearing the article to be bored or drilled being placed upon the said table. The
several pinions on the second shaft are preferably in one casting and are capable
of being slided along the shaft having a feather key travelling in a keyway or
groove on the shaft and a set screw for fastening the pinion casting in any required
position relatively to the toothed wheel on the first shaft. The plummer blocks
for the second shaft are capable of being moved nearer to and further from the
first shaft (according to the size of the pinion in gear) and are preferably mounted
upon metal slides. For slow speeds the first shaft may be provided with an
additional toothed wheel of lesser diameter arranged to gear into one of the
pinions of larger diameter.
Improvements in Hand Power Boring or Drilling Machines.
I, JOSEPH HARDMAN, of Greenbank Yard, Victoria Street, Preston, in the
County of Lancaster, Wheelwright and Builder, do hereby declare the nature of
this invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement:-
This invention has for its object to provide a hand power boring or drilling
machine of convenient form for use by wheelwrights blacksmiths and the like and
with a handy means for altering the speed gear of such a machine to suit the
various sizes of holes to be bored or drilled.

page_text: At Figs. 3 and 4-the latter being another plan view-is shewn an arrange-
ment whereby the improved apparatus may be utilized for circular saw work
and at
Figs. 5 and 6 are shewn end and plan views respectively of the said apparatus
arranged for "tanging" wheel spokes or reducing their outer ends to the form of
round pins to fit into holes in the wheel felloes.
The shaft 1 having the fly wheel 2 and handle 3 is mounted in the plummer
blocks 4, 4, secured to the upper side of the stand or framing 5. 6 is the second
shaft mounted in plummer blocks 7, 7, capable of being moved and secured in a
position nearer to or further from the shaft 1. 8 is a toothed wheel fastened upon
the shaft 1 (preferably by means of a set screw) and gearing into (as shewn in the
drawings) the smaller of two pinions 9 and 10 which are preferably in one piece or
casting and capable of being slided along the shaft 6 there being a feather key
(not shewn in the drawings) which travels in the groove or keyway 11. 8* is the
additional toothed wheel available when in gear with the larger pinion 10 for, slow
speeds. 12 is a hand lever for moving the pinions 9 and 10 and holding or
retaining them in working position. The shaft 6 is capable of sliding horizontally
through its bearings 7, 7, the feed to the drill or boring bit 13 being effected in
the case of wood by means of the lever handle 14 and in the case of metal by
means of the additional screw spindle and handle 15. The boss and coupling 16
is a fixture on the shaft 6. 17 is the horizontal table movable vertically in slots
or grooves 18, 18, by means of the screw 19 and handle 20. Upon the table 17
the articles to be drilled or bored are fastened or held in the required position.
At Figs. 3 and 4 a circular saw 24 is shewn mounted in the usual way upon the
end of the shaft 6 an additional raised and inwardly projecting or overhanging
table 17 being provided and having an adjustable guide rest 17° and attendant
parts of the usual kind.
At Figs. 5 and 6 an outwardly extended table or platform 22 having an outer
supporting stand or leg 23 is provided and upon this platform 22 is an adjustable
vertical centre piece 28 around which a wheel nave 24 may be rotated in the usual
manner. The ends of the spokes 25, 25, are fastened or held in the required position
between the top of the stand 26 and the screw clamp 27 and the rounding of the
spoke ends is effected by the rotation of the cutting bit 13.

page_text: Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what I
claim is
1. In a boring or drilling machine the combination with toothed wheel gearing
of the kind described and shewn in the drawings of a fixed shaft and a second
shaft movable as regards its proximity to the fixed shaft and movable also in the
direction of its own length substantially as hereinabove described and shewn in
the drawings.
2. The combination with toothed wheel gearing and shaft apparatus of the
kind described in Claim 1 of a table or platform adjustable vertically substantially
as hereinabove described and shewn in the drawings for the purpose set forth.
Dated this 14th day of March 1896.
