RICHARD RUSSELL GUBBINS, Civil Engineer, and JAMES WHITESTONE, Civil
Engineer, both of Upper Thames Street, in the City of London. AN IMPROVED
ARRANGEMENT OF DRIVING GEAR FOR TRANSMITTING POWER FROM ANY PRIME
MOVER TO MACHINES, TOOLS, OR APPARATUS WHICH REQUIRE TO BE DRIVEN."
Our Invention relates more particularly to the means of transmitting power to
tools or machines which are capable of being moved about and placed in various
positions, in order that they may be the more conveniently arranged to do the work
for which they are intended to be employed.
In carrying out our Invention, we make use of the ordinary horizontal shafting,
which is mounted in stationary bearings in the usual manner, and in addition
thereto we employ a stationary bracket provided with suitable bearings to receive
a short counter shaft, on one end of which is mounted a pulley whereby motion is
communicated to the short counter shaft from the main driving shaft of the build-
ing. On the other end of the counter shaft is keyed a bevil pinion, which gears into
and drives a similar bevil pinion on the upper end of a short vertical shaft which is
mounted in bearings in the fixed bracket. Another bevil wheel is keyed on the
lower part of the vertical shaft, which also carries a forked swivel frame, which is
capable of turning on its centre of motion, independent of the vertical shaft on
which it is mounted. This swivel frame carries a short horizontal axle or shaft on
the ends of which are mounted loosely two grooved pullies, so that they can rotate on
their shaft in opposite directions. On the inner side of eacli of these pullies (and cast
rD. 21

page_text: therewith) is a bevil wheel which gears into the teeth of the bevil wheel on the
short vertical shaft, so that as the latter rotates, it drives the two pullies at uniform
speed, but in opposite directions. Over these pullies passes an endless band, from
any convenient part of which is suspended a pulley carrying a weight for the pur-
pose of keeping the driving band taut on the pullies. The other part of the
driving band passes down to and around the pulley of the tool or machine that
requires to be driven, and as the two driving pullies in the swivel frame above are
capable of moving round horizontally in either direction, it will be understood that
these pullies will always adapt themselves to the position of the machine or tool to
be driven. If the tool to be driven (a drill for instance), be required to act in a
variety of positions so as to bore holes either in a vertical, horizontal, diagonal, or
other angular position, the tool carrier must be specially constructed and arranged
for the purpose. To this end the tool holder is mounted in bearings in a bracket,
which is supported on a horizontal arm or shaft, securely held in a spring clip or
clamp, which may be loosened when required, so that the arm or shaft. may be
turned round on its axis, so as to place the tool at any desired angle, after which it
may be tightened again in its new position. The spring clip or clamp which holds
this arm is cast or firmly attached to a round disc in which are made two segmental
or curved slots to receive screwed pins fixed in the face of another disc behind, so
that by screwing up nuts on these pins, the two discs will he securely held together
and form a temporary stationary bearing for the horizontal bracket shaft.
The back disc is provided with a socket bearing, through which passes a vertical
spindle, on which it may be turned round and raised or lowered at pleasure. This
spindle is screwed at its lower end, so that it may be raised or lowered and adjusted
with accuracy: the lowered end of this spindle is provided with clamping jaws (like
a vice), so that it may be temporarily attached to a table or other convenient fixed
support. By thus combining a number of these spring clips or clamps adapted to
various parts of the apparatus a kind of universal joint is produced which will
admit of the tool being placed in any position, and at any angle, as may be required,
according to the nature of the work to be done.

Engineer, both of Upper Thames Street, in the City of London. "AN IMPROVED
ARRANGEMENT OF DRIVING GEAR FOR TRANSMITTING POWER FROM ANY PRIME
MOVER TO MACHINES, TOOLS, OR APPARATUS WHICH REQUIRE TO BE DRIVEN."
Our Invention relates more particularly to the means of transmitting power to
tools or machines which are capable of being moved about and placed in various
positions, in order that they may be the more conveniently arranged to do the
work for which they are intended to be employed.
The mode in which we carry out our Invention will be best understood, by
referring to the accompanying Drawings, in which Fig. 1,Sheet 1, is a side elevation
of our improved driving gear: Fig. 2 is an end elevation of the same; and Fig. 3 is
a similar view of the opposite end.
lu adapting our Invention for transmitting motion from any prime mover to al

page_text: machine or tool we make use of the ordinary horizontal shafting, which is mounted
in stationary bearings in the usual manner; and in addition thereto, we employ a
stationary bracket b, provided with suitable bearings to receive a short counter-
shaft. a, on one end of which is mounted a pulley, whereby motion is communicated
by means of a driving band to the short countershaft a from the main driving shaft
of the building, but not shown in the. Drawing. On the other end of the counter-
shaft a is keyed a bevil pinion d, which gears into and drives a similar bevil pinion
e on the upper end of a short vertical shaft e¹, which is mounted in bearings in the
fixed bracket. b. Another bevil wheel e² is keyed on the lower part of the vertical
shaft et, which also carries a forked swivel frame f, which is capable of turning.com.
pletely round in either direction on its centre of motion, independent of the vertical
shuft e on which it is mounted. This swivel frame, which is shown detached in
front and side elevation, at Figures 4 and 5, carries a short horizontal axle, or
shaft f, on the ends of which are mounted loosely two grooved pulleys g, g, so that
they can rotate on their shaft f¹ in opposite directions. On the inner side of each
of these pulleys 9, 9, (and cast therewith), is a bevil wheel g', which gears into the
teeth of the bevil wheel e on the short vertical shaft e¹, so that as the latter rotates
it drives the two, pulleys y, g, at uniform, speed; but in opposite directions. Over
these pulleys passes an endless driving band h, from any convenient part of which. is
suspended a pulley i, carrying a weight. j. for the purpose of keeping the driving
bandh taut on the pulleys g, g. The other part of the driving band h passes down
to and around the pulley of the tool or machine that requires to be driven, and as
the two driving pulleys 9, 9, in the swivel frame ƒ above are capable of moving
round horizontally in either direction, it will be understood that these pulleys
,, can always be adapted to the position of the machine or tool to be driven.
It will be understood that as a positive motion is imparted to the driving pulleys
,, by means of the bevil gear they cannot slip, and as they are driven in opposite
directions, and the driving band passes over both of them, a considerable amount of
adhesion, and consequently of driving power, is obtained.
If the tool to be driven (a drill, for instance) be required to act in a variety of
positions, so as to bore holes either in a vertical, horizontal, diagonal, or other
angular position, the tool carrier must be specially constructed and arranged for the
purpose. To this end the tool holder is mounted in bearings in a bracket, which is
supported on a horizontal arm or shaft securely held in a spring clip or clamp,
which may be loosened when required, so that the arm or shaft may be turned
round on its axis, so as to place the tool at any desired angle, after which it may be
tightened again in its new position.
This arrangement is shown in Sheet II., in which Fig. G is a side elevation and
Fig. 7 au end elevation of the tool holder; Figures 8 and 9 are front and side views
of the spring clip and its accessories detached. This spring clip or clamp k, which
holds the bracket arm 2, is cast on or firmly attached to a round disc ', in which
are made two segmental or curved slots to receive screwed pius m, m, fixed in
the face of another disc k behind, so that by screwing up nuts on these pins m, m,
the two discs and k* will be securely held together and form a temporary
stationary bearing for the horizontal bracket shaft. The back disc * is provided
with a socket bearing n, through which passes a vertical spindle o, on which it may
be turned round and raised or lowered at pleasure. This spindle is screwed at
its lower end and the tool holder is attached thereto by means of the socket
bearing n, which is split or divided, so as to act as a spring clip. The tool holder
may therefore be raised or lowered and adjusted on the spindle
with accuracy.
The lower or screwed end of this spindle is provided with clamping jaws
', o, (like a vice), so that it may be temporarily attached to a table or other
convenient fixed support.
The tool is mounted in a bracket p', which also carries the speed pulleys y,
which are driven by the band h. The tool and its speed pulleys may therefore be
turned around on the vertical axis, so as to bring the pulleys g opposite to the
driving pulleys g, g, of Figures 1, 2, and 3, and these parts may be clamped in

page_text: any desired position by means of the clip or clamp p. By thus combining a
number of these spring clips or clamps adapted to various parts of the apparatus,
the several parts can be so arranged as to admit of the tool being placed
in any position and at any angle, as may be required, according to the nature
of the work to be done.
Having now described our Invention of an improved arrangement of driving
gear for transmitting power from any prime mover to machines, tools, or
apparatus which require to be driven, and having explained the manner of
carrying the same into effect, we claim as the Invention secured to us by Letters
Patent as aforesaid,-
Mounting a pair of driving pullies in a swivelling frame which is capable of
being turned completely round on its vertical axis as herein set forth, so that these
driving pulleys may be brought into any desired position to drive machinery or
tools, as above described.
We also claim imparting a positive motive. in opposite directions to the driving
pullies by means of bevil gear, as and for the purposes herein set forth.
We further claim mounting the drill or other tool, together with the driving gear
connected therewith in the manuer herein shewn and described, so that these parts
may be secured in any desired position, or the tool set at any required angle,
as and for the purpose herein set forth.
In witness whereof, I, the said James Whitestone, have hereunto set my hand
and seal, the Fifth day of December, in the year of our Lord One
thousand eight hundred and seventy-seven.
