I, ARTHUR ALBERT TATTERSALL, of Millhill Tool Works, Millhill, Blackburn,
Engineer, do hereby declare the nature of this invention to be as follows:--
This invention relates to a small machine which can be fitted to a bench
or in other suitable situation and by means of which articles can be drilled,
ground and polished or buffed.
The improved machine consists of a frame which can be fixed to the bench in
any suitable and well known manner. This frame carries at its upper end a
revoluble spindle which at one end carries a universal chuck for holding drills
and at the other end a taper screw upon which polishing buff wheels, mops,
brushes, glaziers, etc., may be fitted. The revoluble spindle carries at its centre
an emery grinding wheel which is preferably held in place by a screw nut which
may be locked by a pinching pin. At one side of the emery wheel is a grooved
pulley for the reception of a driving cord or its equivalent.
Carried also in the frame, at a position below the first spindle, is a second fixed
spindle upon which can revolve a grooved driving wheel round which the driving
cord aforesaid is passed. To or on the hub of this wheel is cast a hollow collar
or box which is provided with teeth or roughened parts at the inside. Working
into these teeth or roughened parts are two, or more, steel pieces or bits which
are loosely held in place in suitable slots or recesses cast or made in a bush or
its equivalent also revolubly secured upon the spindle. Attached to the bush,
or a barrel forming an extension of the bush, is one end of a spring whose
other end is secured in a hollow casting or box attached to the frame. The fixed
spindle passes through the frame and the bush. A leather strap, or a band or
cord, is secured to the barrel part of the bush or to an independent barrel and
to a treadle or other suitable and well known device for the purpose of driving
the grooved wheel.
The upper end of the frame is also provided with a pivotted rest or its
equivalent.
The action is such that at each unwinding of the leather strap from the barrel
the steel pieces or bits in the slots catch in the teeth of the collar of the driving
wheel and cause it to revolve. The spring, which is attached to the loose bush,
is opened during the unwinding of the strap but immediately the latter is let
go or slackened it contracts and winds up the loose strap ready for the next
downward pull.
The invention can be adapted so as to work as a combined grinding and
polishing machine or a combined grinding and drilling machine or simply as
a grinding or a drilling or a polishing machine.

An improved wing, and
I, ARTHUR ALBERT TATTERSALL, of Millhill Tool Works, Millhill, Blackburn,
Engineer, 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 relates to a small machine which can be fitted to a bench
or in other suitable situation and by means of which articles can be drilled,
ground and polished or buffed.
In order that my said invention may be properly understood I have hereunto
appended an explanatory sheet of drawings, whereon,
Fig. 1 is a front elevation of the machine."
Fig. 2 is a side elevation of the same.
Fig. 3 is a vertical section of the machine.
Fig. 4 is a sectional view of the driving gear taken on the line X-X Fig. 3.
Figs. 5 and 6 are detail views of the bits, or movable teeth of the driving gear
drawn to a larger scale.
Fig. 7 is a diagram showing the machine as driven by means of a treadle.
Referring to the drawings whereon the same reference letters wherever repeated
indicate the same parts.
C
The improved machine consists of a frame a which can be fixed to a bench b,
table or other suitable place in any well known manner. This frame carries, at
its upper end, a revoluble spindle c which, at one end, carries a universal chuck d
for holding drills and at the other end has a taper screw c¹ upon which polishing
buff wheels, mops, brushes, glaziers, etc., may be fitted. The revoluble spindle
has fitted on it and held in place by a pin h a partly screwed sleeve g which is
made with a grooved pulley for the driving cord or equivalent. Carried at
the centre of the solid sleeve is an emery grinding wheel e which is
preferably, held in place, against the pulley i, by a screw nut f. The pulley i
may, if desired, be secured to the spindle c.
Carried also in the frame a, at a position below the spindle c, is a second
stationary spindle j, upon which can freely revolve a grooved driving wheel k
round which the driving cord aforesaid is passed.
On the hub of this wheel k is cast a hollow collar or box m which is provided
with teeth or equivalent m¹ round the inside. Working into these teeth are
two (or more) steel teeth or bits m² which are loosely held in place, in suitable
V shaped slots or recesses n (see Fig. 4) cast or made in a disc o, or its equiva-
lent, also revolubly secured upon the spindle j. Attached to the barrel o forming
an extension of the disc o, is one cud of a spring whose other end is secured
in a hollow casting or box secured rigidly to the frame a by means of the
bolts which is passed through the frame and a lug on the box. The fixed
spindle passes through the frame a and the disc o. A leather strap r, or a
band or cord, is secured to the barrel part o¹ of the disc o and to a treadle s¹
(Fig. 7) or other suitable and well known actuating device for the purpose of
driving the grooved wheel k.
The upper end of the frame a may also be provided with a pivotted rest t, or
its equivalent, see Fig. 7.
As shown at Figs. 5 and 6 the teeth or bits m² are made with pointed front
ends and rounded back ends.
The action is such that at each unwinding of the leather strap from the
barrel, due to a downward pull, the disc o revolves and the steel teeth or
bits me in the slots n catch in the internal teeth m¹ of the collar m of the driving

page_text: wheel and cause it to revolve also. The spring p, which is attached to the
barrel o, is opened or expanded during the unwinding of the strap r but
immediately the latter is let go or slackened it contracts and revolves the disc o
and barrel of in a reverse direction thereby winding up the loose strap again
ready for the next downward pull. At each winding up of the strap the
teeth m² assume the dotted positions Fig. 4 and lie with their points clear of
the teeth m so that the motion of the wheel is not reversed. By working
the treadle (Fig. 7) the pulls on the strap will cause the wheel to rotate
and thereby drive the spindle c as will be readily understood. The wheel k is
made heavy enough to serve as a fly wheel.
The invention can be adapted so as to work as a combined grinding and polish-
ing machine, a combined grinding and drilling machine, or simply as a grinding
or a drilling or a polishing machine.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I consider novel and desire to claim is:
1. The general arrangement and combination of parts of the machine sub-
stantially as herein before described with reference to the drawings annexed.
2. The mechanism for rotating the driving wheel comprising an internally
toothed collar or its equivalent on the wheel, a disc working within the collar,
recesses in the disc, bits or teeth loosely fitted in the recesses and capable of
engaging with the teeth of the collar and means for actuating the disc, substan-
tially as herein before described.
3. The spindle (c) made with a taper screw at one end and having a chuck at
the other end, a screwed sleeve being fitted to it and a grinding wheel held in
place on the sleeve between a driving pulley which is made one with or secured
to the sleeve and a screw nut, substantially as herein before described.
Dated this 23rd day of November 1899.
