TRUVIDIONAL DE MULTIUATION.
Improvements in Machinery or Apparatus for Drilling, Applicable.
also for Burnishing or Polishing and other like Purposes.
We JACQUES BINKO of 11 Stradbroke Road Highbury New Park in the County
of Middlesex Manufacturer and THOMAS HULBERT of 4 Broad Street Buildings in the
City of London, Solicitor do hereby declare the nature of this invention to be as
follows:-
:
This invention relates more particularly to improvements in that class of machinery
or apparatus commonly known as Hand Drills" the improved drill being
continuous in action and applicable for all purposes where drills are employed
whether for large or small work, its peculiar construction rendering it applicable for
use in hitherto inaccessible places, and has for its object simplicity and economy of
construction, efficiency in action and greater compactness combined with lightness.
It will also be found advantageous when furnished with a burnishing or polishing
appliance in lieu of a Drill bit to Jewellers, Watch and Clock Makers, Dentists and
the like for polishing gold, silver and other metals and ivory.
According to this invention the improved Drill consists of a hollow sleeve or
tubular spindle through which the drill spindle carrying the Drill works; upon this
hollow or tubular spindle is mounted a pulley capable of being rotated by means of
a cord or strap, which pulley contains a coiled spring one end of which is secured to
a box on the hollow spindle round which it is coiled and the other end butts against
a projection or otherwise in the interior of the pulley. The outer face of the pulley
carries a spring pall which engages with a ratchet or toothed wheel fast on the drill
spindle, a cord or strap being conveniently attached to the outer circumference of
the pulley for imparting the necessary rotary motion thereto. By the side of the
ratchet wheel and also keyed or otherwise attached to the drill spindle is an
ordinary balance or fly wheel. The drill spindle is retained within the hollow or
tubular spindle by means of a screw or pin in the tubular spindle which engages
into a circumferential slot or groove formed round the drill spindle and the inner
end thereof works in an adjustable coned centre screwed into a boss which is screwed
onto the end of the hollow or tubular spindle. Over the hollow spindle is fitted a
convenient handle for holding the drill in any required position and all the parts are
held together by means of a lock nut on the end of the said adjustable screwed coned
centre on loosening which Lock nut the coned centre may be screwed or unscrewed
as required.
•
When the Drill is to be secured to a work bench, vice, lathe, or other convenient
support for working it by means of a treadle or otherwise the handle is provided
with a suitable clip or fixing piece for the reception of the vice or clamp which
attaching piece may be made to turn or swivel away from the handle for the purpose
of taking the drill apart. Upon this fixing piece or on the shoulder or bolster formed
on the hollow spindle which fits against the inner end of the handle may also be
provided a guide or eyelet for the actuating cord or strap.
On pulling the actuating cord or strap which is wrapped round the circumference
of the pulley, it is rotated and the spring becomes uncoiled which movement of the
pulley through the intervention of the pawl and ratchet imparts a quick rotary
motion to the drill spindle in one direction only, the momentum thus imparted thereto
maintaining the same in motion whilst the spring is recoiling itself and the cord or
strap becoming again wrapped round the pulley, thus it will be seen that by repeating
the action on the pulley by means of the cord or strap a continuous rotary motion
of the drill spindle at great speed will be maintained.

page_text: Although I have described a pall and ratchet as the means for transmitting the
motion from the pulley to the drill spindle I do not confine myself thereto as any
other convenient arrangement may be employed such as gear wheels, cams, clutch
action or the like.
The Drill may if desired be worked by steam or any other convenient prime mover
by means of a pulley situate beside the balance or fly wheel and keyed or otherwise
attached to the drill spindle, said pulley being adapted to receive a driving cord or
strap.
By the aid of this invention it has been found that one revolution of the pulley by
means of the cord or strap may he made to produce six revolutions of the Drill
spindle thus for 30 revolutions of the pulley 180 revolutions of the Drill spindle
would be obtained.
The apparatus will be found most advantageons when fitted with the necessary
appliances in lieu of Drilling bits for burnishing or polishing small articles such as
those produced by Jewellers, Watch Makers, Dentists and the like as the spindle can
be made to revolve at a high speed say from 300 to 400 revolutions per minute.

COMPLETE SPECIFICATION.
Improvements in Machinery or Apparatus for Drilling, Applicable
also for Burnishing or Polishing and other like Purposes.
We JACQUES BINKO of 28 Cornwall Road, Stroud Green, in the County of
Middlesex, formerly of 11 Stradbroke Road, Highbury New Park, in the County of
Middlesex, Manufacturer, and THOMAS HULBERT of 4 Broad Street Buildings in the
City of London, Solicitor, do hereby declare the nature of the said invention and in what
manner the same is to be performed to be particularly described and ascertained in
and by the following statement :-
The said Invention relates to improvements in machinery or apparatus for drilling
applicable also for burnishing or polishing and other like purposes.
It consists essentially in so arranging and combining a drill spindle adapted to
hold drill bits, burnishers, polishers, or other like tools, a bearing or sleeve for the
same, an adjustable bearing or centre for the pivot thereof, a convenient handle, and
improved means whereby a continuous high speed rotary motion is imparted to the
drill spindle, as to produce a simple, compact, and self contained, continuous motion
hand drill, which can be held in one hand, and driven by the other at a high speed,
and can be employed for drilling the smallest holes, burnishing, or polishing, in
hitherto inaccessible places. It will be found of especial value to Jewellers, Watch
and Clock Makers, Dentists, Locksmiths, and the like, for drilling small holes, and
polishing gold, silver, or other metals, and ivory.
Means are also provided whereby the apparatus may if desired be held in a vice,
and driven from a treadle, or by power.
We will now proceed to describe the said invention more particularly referring to
the accompanying drawings in which similar letters refer to corresponding parts in
all the figures.
Fig. 1 is a view of the apparatus complete partly in section shewing clearly the
manner in which the drill spindle, its bearing or sleeve, and the adjustable bearing
or centre for its pivot, are arranged within and secured to the handle.
Fig. 2 is a longitudinal section of part of the apparatus, shewing clearly the
improved means employed for transmitting a continuous high speed rotary motion to
the drill spindle.
Fig. 3 is an end view of fig. 2 the fly wheel on the drill spindle being removed.
Fig. is a view of the underside of fig. 1 (the drill spindle and its adjuncts not
being shewn) illustrating more clearly the guide for the actuating cord or band.

page_text: a is the drill, spindle within which the drill bits a¹, burnishers, polishing buffs, or
other like tools to be employed, are secured by the set screw b, in the usual manner.
c.is a sleeve forming a bearing for the drill spindle a, and accurately fitting the
same at one end, into the other end of which sleeve is screwed the adjustable centre
or bearing d, for the pivot of the drill spindle a. This spindle a is prevented from*
slipping out of the sleeve c, by means of the set screw c', which protrudes through
the sleeve, and engages with the circumferential groove a", formed around the
spindle a e is a conveniently shaped handle fitting over the sleeve c, and abutting
against the boss, fixed thereto. is a screw collar, screwing onto the exterior of
the end of the sleeve c, and serving to retain the handle e in its place. is a lock-
nut on the threaded spindle of the adjustable centre or bearing d, which, when
screwed tight, maintains the said centre, and also the collar g, securely fixed. By
loosening this lock nut h, the centre d may be readily adjusted. i is a drum or
pulley (here shewn in the form of a spring box) mounted, and turning freely, upon
the sleeve c, with which it is connected by a coiled spring k, one extremity of which
is secured to the sleeve c, whilst the other extremity abuts against a projection 1,
within the drum or pulley i. m is a flexible cord or band, secured at one end to,
and coiled around, the drum i, in such a direction as to uncoil, or increase the tension
of the spring k, when pulled so as to rotate the drum. n is a spring detent or pawl
secured to the drum i, and engaging with the teeth of a ratchet wheel o, fast on the
drill spindle a. p is a guide for the cord or band m, which passes through the slot
therein. This guide is pivotted to the boss fat q, and secured to the handle e by a
screw.r. On removing this screw, the guide may be turned on its pivot out of
the way of the drum i if necessary, as in the case of coiling a band around the
drum for example. is a convenient finger ring secured to the extremity of the
band m, and serving, in conjunction with the guide p, to prevent said band uncoiling
from the drum i.
The action of the apparatus is as follows:-
Upon pulling the cord m, (which is normally maintained coiled around the drum i
by the tension of the spring k), by means of the finger rings, the drum will be
rotated in the direction of the arrow (fig. 3), and its detent or pawl n, by engaging
with the teeth of the ratchet wheel o, fast on the drill spindle a, will cause said
spindle to rotate. The pull on the cord m is then relieved, and the tension of the
spring k, which exerts its force against the pull of the cord, recoils it around the
drum i, the spindle a continuing to revolve meanwhile through the momentum of
its fly wheel t The pull on the cord is then repeated, and so on, each successive
puil imparting fresh momentum to the drill spindle, the speed of which is increased
in proportion to the quickness and sharpness of the pulls.
If desired the apparatus may be held in a vice, in lieu of in the hand, the guide p.
serving also as a clip piece for the jaws to grasp; the free extremity of the cord m
being in this case preferably attached to a treadle.
Should it be desired to employ power to drive the apparatus, a driving band may
be passed around the pulley u, fixed to the spindle a, and the spindle driven direct,
in lieu of employing the hereinbefore described peculiar arrangement of spring drum
or pulley combined with a pawl and ratchet.
In lieu of constructing the drum i in the form of a spring box, as illustrated, we
may, for the sake of economy, employ a simple pulley open at its ends, and connected
with the sleeve c by a spring,.in the manner hereinbefore described.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is
1. The improvements in machinery or apparatus for drilling, consisting in the
combination and arrangement of a drill spindle carrying a fly wheel, a bearing or
sleeve containing an adjustable centre or bearing for the pivot of said spindle, a
convenient handle, and means substantially as specified for transmitting a continuous
