PROVISIONAL SPECIFICATION.
Improvements in and relating to Shafting.
I, WILLIAM Ross of No. 32 Torrance Street in the City of Montreal in the
District of Montreal and Province of Quebec Dominion of Canada, Superintendent
of Bridge Building, do hereby declare the nature of this invention to be as
follows:-
This invention relates to portable drills and shafting or mechanism for conveying
the rotary motion of a main driving shaft, or other rotatory part, in a number of
different directions from a single point of connection with the main shaft to a
working tool, such as a drill piece, reamer or the like, secured to the opposite and
free end of the mechanism, and which can be applied or held to work at various
angles such as required during the construction of large metal boilers, girders, etc.
The object of the invention is to secure first a greater latitude of free movement
for the device, secondly, the automatic shortening and lengthening of the parts so
as to render the mechanism more compact and convenient to handle particularly at
times when the work is situated close to the point of connection with the main
shaft, and thirdly to allow of the stoppage of the tool when desired without
necessarily stopping the main shaft also.
The invention consists first in a free sliding movable connection of the portable
shaft mechanism proper with the main shaft; secondly, in the construction of the
portable shaft mechanism itself this comprising, in the main, a rotatory guide
section having in turn a universal joint connection with the part having a movable
connection with the main shaft, and carrying an extension spindle (hereinafter
further described) or bar, adapted to project for some distance from the free end of
said guide and be rotated with it, or be drawn within such guide for some
distance so as to shorten the length of the mechanism as a whole without however
interfering with its rotation or that of the tool; and thirdly in a special construction
of the outer end of the said extension spindle and of its connections with the guide
whereby upon moving it for an extreme distance into che guide its rotation with
same can be prevented and the tool held stationary if so desired for any purpose.
The invention may be said to embody as novel features; first, the combination
with a main driving shaft invariable as to position; of a portable shafting with a
free sliding tool-carrying extension therefrom; a free pivotal sleeved hanger and
devices connecting said hanger with said main driving shaft whereby it may be
freely rotated about same; secondly, the combination with a main driving shaft
invariable as to position, of a portable shafting with a free sliding tool-carrying
extension therefrom and a free sliding sleeved hanger connection between said
main driving shaft and said portable shafting whereby the latter is variable in
position longitudinally of same, by direct pulling upon it in line with said main
shaft; thirdly, the combination with a main borizontal driving shaft invariable as to
position of a portable shafting with a free sliding tool carrying extension therefrom
and suspended from said driving shaft by a sleeved hanger free to rotate about and
slide along same unchecked and freely variable in position relatively to same, by
direct pulling upon it in line with said main shaft or laterally thereto; fourthly,
the combination with a main driving shaft, of one or more bevel gear wheels
mounted thereon, a spindle arranged at right angles to said main driving shaft, a
bevel gear wheel on one end of said spindle adapted to intermesh with the gear
wheels on said shaft; a rotatable guide with universal joint connection between one
end of same and said spindle; and a tool carrying extension from the opposite end
| of said guide adjustable, without rotation, relatively to, and adapted to be rotated

page_text: by such guide; fifthly, the combination with a rotatable guide and means for
rotating same; of a tool carrying extension movable in and out of said guide and
being for the greater part of its length of an angular cross section corresponding to
that of an aperture in the end of said guide, through which it works and whereby
it is rotated, and of a circular cross section towards its outermost end; sixthly, the
combination with a rotatable guide and means for rotating same of a tubular counter-
balance weight, suspending cord and pulley, and a tool carrying extension movable
in and out of said guide and connected by a swivelling attachment with one end of
said suspending cord as set forth; seventhly, the combination with a main horizontal
driving shaft invariable as to position, of a portable shafting comprising a hanger
having a pivotal and sliding connection with said main shaft; one or more bevel
gears mounted upon and adapted to slide on and be rotated by said shaft; a
vertical spindle carried by said hanger and having a bevel gear on its upper end
adapted to mesh with said bevel gear or gears on said main shaft; a rotary guide,
a ball-link-and-fork joint connection between said guide and spindle, a tubular
counterbalance weight suspended within or without said rotatory guide; a rod
extension attached to one end of the suspending cord for said weight and a tool
holder at the end of said rod extension with ball-link-and-fork joint connection
between it and said extension, the said rod extension being square in cross section
and adapted to project through a square aperture in the lower end of said rotatory
guide as set forth and eighthly, the combination with a main horizontal driving
shaft invariable as to position a sleeved hanger having a pivotal and sliding con-
nection with said main shaft, a rotatable guide and means for rotating same of a

Improvements in and relating to. Shafting.
I, WILLIAM Ross of No. 32 Torrance Street in the City of Montreal in the
District of Montreal and Province of Quebec, Dominion of Canada, Superintendent
of Bridge Building, 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 shafting or mechanism for conveying the rotary motion
of main driving shaft or other rotatory part in a number of different directions
from a single point of connection with the main shaft to a working tool such as
a drill piece reamer or the like secured to the opposite and free end of the
mechanism and which can be applied or held to work at various angles such as
required during the construction of large metal boilers, girders, etc.
The object of the invention is to secure first a greater latitude of free movement
for the device; secondly the automatic shortening and lengthening of the parts so
as to render the mechanism more compact and convenient to handle particularly
at times when the work is situated close to the point of connection with the main
shaft and thirdly to allow of the stoppage of the tool when desired without
necessarily stopping the main shaft also.
The invention may be said to consist first in a free sliding or movable connection'
of the portable shaft mechanism proper with the main shaft; secondly in the
construction of the portable shaft mechanism itself this comprising in the main a
rotatory guide section having in turn a universal joint connection with the part

page_text: having a movable connection with the main shaft and carrying an extension spindle
or bar adapted to project for some distance from the free end of said guide and
be rotated with it or be drawn within such guide for some distance so as to shorten
the length of the mechanism as a whole without however interfering with its
rotation or that of the tool and thirdly in a special construction of the outer end
of the extension spindle and of its connections with the guide whereby upon
moving it for an extreme distance into the guide its rotation with same can be
prevented and the tool held stationary if so desired for any purpose.
For full comprehension however of the invention reference must be had to the
annexed drawings forming a part of this Specification in which like symbols
indicate corresponding parts and wherein :-
Fig. 1 is a side elevation of the shafting partly in section; Fig. 2 an elevation
of same taken at right angles to Fig. 1 and also partly in section; Figs. 3 4 and 5
being transverse sections respectively on the lines yy and Fig. 1.
a is the usual main shafting carried by hangers a' and in this case having a
longitudinal groove «².
bare two bevel gear wheels mounted loosely on the shaft & and in reverse
positions so that their toothed surfaces will face each other and each be in mesh
with a third bevel gear wheel e mounted on the upper end of a second shaft or
spindle c suspended vertically at right angles below the main shaft a in a forked
banger & the forked ends d¹¹ of which are perforated to fit loosely on the shaft a
at a short distance in the rear of the respective gear wheels bb².
On the shaft a between the respective gear wheels and the forked ends
of the hangers & clutch blocks or collars e e¹ are mounted and provided with
feathers to fit the groove a' of the shaft a as well as having their surfaces
which face the gear wheels clutch-faced or toothed to engage with the like
surfaces of the rear faces of the gear wheels bin any of the usual ways bell
crank levers g g pivotted at / to the hanger d having upwardly projecting ends or
arms connected respectively with the collars e el and also connected together by
bar and their opposite or horizontal projecting ends adapted to be operated as
may be desired by the operator for the purposes hereinafter set forth.
The vertically hanging shaft e¹ which is suitably journalled in the hanger d
extends for a short distance below the same and terminates in a thin neck e² on the
end of which is the ball part of a ball-link-and-fork-joint of the usual type the
several parts of which including that just mentioned are lettered respectively
kkk.
The body of the fork portion 2 has a square aperture formed in it to receive
the square neck piece projecting from the upper blocked end of a length of
tubing L which forms a guide for a counterbalance weight m of tubular form
suspended by a cord m³ over a grooved pulley n axially mounted at the upper end
of such tube. The cord mis looped at one end around a pulley m² secured on
the weight while the opposite ends are attached to the eye p of a swivelling con-
nection with which is connected the upper end of a square bar y free to work
through the weight m extending down and outward through a square aperture q'
in the lower blocked end of the tube L the lower end of such bar being diminished
in size and made circular in section as shown at for a purpose hereinafter
described and further extended to carry a collar and a second bail-link-and-fork-
joint the parts of which are lettered respectively s s¹s s³ from which ball parts a
holder t extends and terminates in a squared socket t' adapted to have removably
secured in it any desired tool such as a reamer drill or the like the first named being
shown in place.
The operation of my invention is as follows :—
By pulling downward the horizontal arm of the pivotted lever g the clutch e
keyed on shaft a is thrown into contact with the bevel gear 6 which through gear c
and ball-link-and-fork-joint kkk imparts a rotary motion to the guide tube L
nd when the square portion of the bar is projected through the aperture in
he lower end of the guide it is also rotated and with it of course the remaining

page_text: parts including the tool but when the bar is drawn sufficiently within the guide to
locate its circular portion in the aperture the tube rotates around it without
disturbing it, its swivelling connection pl preventing the cord m¹ from being twisted.
Whenever it is desired to bring the tool into action the bar g is drawn outward
against the inward pull of the counterbalance weight by means of the handle wo
mounted loosely in a groove on the holder t so that the holder can be rotated while
When the tool is
the handle can be held and used to set the position of the tool.
not required it is automatically drawn up into its normal position by the counter
weight m the extension bar entering the guide till its circular portion r enters the
square hole in the lower stopped ends of the guide as before mentioned. The
tube thereby loses its hold on same allowing the bar to become stationary and
the tube free to rotate around it. To reverse the direction of the rotation of the
drill the lever glis operated similarly to the one g and throws clutch e out of
contact with bevel gear by means of the bar and simultaneously the clutch el
into contact with bevel gear which consequently reverses the direction of
rotation of the gear wheel c. To stop the drill altogether without stopping the
main shafting it is only necessary to draw down whatever horizontal arm of the
levers is above its normal or horizontal position to such normal or horizontal
position as shown in Fig. 1 and both clutches will be thrown out of contact
with their bevel gears when as it will be readily seen the portable shafting and
its operating gears will become stationary. As all the parts mounted on the main
driving shaft are mounted loosely so far as movement longitudinally of such shalt
is concerned the apparatus as a whole can be moved backward and forward along
said shaft between the hangers thereby giving it together with its universal joint
and telescopic connections an extensive working area.
b
Of course it is not necessary that the reversing gear and clutch mechanism should
be provided in every case as a single bevel gear on the main shaft without any
clutch mechanism can be used although this necessitates the continuous rotation of
the rotary guide.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The combination with a main driving shaft invariable as to position-of a
portable shafting with a free sliding tool-carrying extension therefrom a free
