Improvement in Portable Power Transmitting Devices.
1, ELBERT DELOS WEYBURN of Lasalle Street Chicago Cook County, State
of Illinois, United States of America Manufacturer, do hereby declare the nature
of this invention to be as follows:-
:-
My invention relates to an improvement, in portable power transmitting devices,
adapted to be moved from place to place in a shop or factory, and be applied to
the desired work in any portion of the room.
The object of the invention is to apply a portable motor to a system of power
transmission where I can use a system of portable shafts and pulleys, together with
a system of overhanging swinging arms which I attach to iny travelling carriage,
and by this means, I obtain a driving power which I can use at any place within
the length of the track.
It will be understood that should I wish to use my travelling motor and carriage
to transmit a driving power from any point in the room within the length of the
track, I can do so. This will be found useful in factories, where it is necessary to
move the machine from one position to another. This is especially desirable in
drills, engraving or wood carving machines and especially handy for cutting
machines of any description.
My invention consists primarily of a carriage travelling on a suitable track, an
electric motor carried thereby, and a series of arms pivoted to swing horizontally
and carrying the cutting tool, said arms being supported from the carriage, and
driving connections carried by the jointed arms and operated from the motor for
driving the cutting tool.
It also consists of a frame or carriage travelling on a suitable track, and an
electric motor carried thereby, of a hollow shaft or tube depending from the
carriage, a driving shaft passing through the same, in operative connection with
the motor, a series of arms pivoted to swing horizontally and supporting at their
outer ends the cutting tool, and driving connections between the driving shaft and
the cutting tool carried by the horizontal arms.
Finally, the invention consists in the various details for supporting the hollow
and solid shafts, for pivoting the horizontal arms, and in various other matters
hereafter described.
"
Suspended from the tracks by means of trolleys or friction rollers is a frame or
carriage, uprights carrying the wheels being passed through the upper part of the
said frame or carriage and secured thereto, and on (preferably) au elongated
portion of the frame is carried an electric motor adapted to furnish the driving
power for the cutting machine, this motor being supplied with the necessary electric
current from a suitable generator the current being collected by trolleys which
may make overhanging contact with an electric cable supported upon J shaped
brackets depending from the ceiling, any form of cut out suitable to the purpose
may be used for starting or stopping the motor. A hollow shaft or tube depends
from the travelling carriage provided with a collar fitting round it and secured to
the under side of the frame; the upper end of this shaft has its interior screw-
threaded and it is kept from vertical displacement by means of a nut having
central opening and having a downwardly extending externally threaded portion
adapted to be screwed through the bottom of the carriage and take into the threads
on the interior of the hollow shaft which is further steadied by a brace or support
attached to the carriage and acting as a truss for the shaft, being held in place by
a

page_text: carriage, and by this means, I obtain a driving power which I can use at any place
within the length of the track.
It will be understood that should I wish to use my travelling motor and carriage
to transmit a driving power from any point in the room within the length of the
track, 1 can do so. This will be found useful in factories, where it is necessary to
move the machine from one position to another. This is especially desirable.in
drills, engraving or wood carving machines, and especially handy for cutting
machines of any description.
My invention consists primarily of a carriage travelling on a suitable track, an
electric motor carried thereby, and a series of arms pivoted to swing horizontally
and carrying the cutting tool, said arms being supported from the carriage, and
driving connections carried by the jointed arms and operated from the motor, for
driving the cutting tool.
It also consists of a frame or carriage travelling on a suitable track, and an
electric motor carried thereby, of a hollow shaft or tube depending from the.
carriage, a driving shaft passing through the same, in operative connection with the:
motor, a series of arms pivoted to swing horizontally and supporting at their outer-
ends the cutting tool, and driving connections between the driving shaft and the
cutting tool carried by the horizontal arms.
Finally, the invention consists in the various details for supporting the hollow
and solid shafts, for pivoting the horizontal arms, and in various other matters,
hereinafter described and referred to in the appended claims.
My invention is illustrated in the accompanying drawings, in which,
Figure 1, is a side elevation illustrating my invention.
Figure 2, is an end view of the travelling carriage, and motor itogether with the
tracks.
Figure 3, is a detail sectional view of the hollow shaft and means for supporting
the same, and the solid driving shaft, certain of the parts being shown in detached
views.
As,herein illustrated,.A, represents the ceiling or overhead beam supporting my
improved apparatus. Brackets a, a, are suspended from said support, and upon
these brackets are secured the track rails b, b. These, rails may be arranged either
in a straight line throughout the length of, or extended around the room in any
desirable, manner.
The brackets a, a, (Fig. 2) are preferably made in such form as to support! both
tracks, the track.rails being secured thereto by a bolt 1, passing through both rail
and bracket, but I may support the apparatus in any other suitable manner.
Suspended from the tracks b, b, by means of trolleys or friction rollers c, c, upon
the upper ends of suitable uprights B, is a frame, or carriage d, of substantially the
construction illustrated, the uprights B, which carry the wheels c, c,' being passed
through the upper part of said carriage or frame, and secured thereto. Carried
preferably upon an elongated portion e-of the frame is an electric motor C; adapted
to furnish the driving power for the cutting machine. This motor is supplied with
the necessary electric current from a suitable generator; the current being collected
by trolleys f, f, herein shown as making overrunning contact with electric
cable 9, 9', supported upon J-shaped brackets, depending from the ceiling.. The
curved shape of the brackets at the lower end, enables me to use overrunning.
trolleys ff. Any desired form of cut out for starting or stopping the motor.may
be used.
D is a hollow shaft or tube depending from the travelling carriage, d. This
shaft is provided with a collar E, fitting around it, and adapted to be secured to
the under side of the frame d. The shaft D, is provided with a screw threaded
interior upper end and is kept from vertical displacement by means of a nut el
having a central opening,. and having a downwardly extending externally threaded
portion; k, adapted to be screwed through the bottom of the carriage d, and take
into the threads upon the interior of the hollow shaft D. This hollow shaft D, is
further steadied by means of a brace or support, El attached at either end to the

page_text: carriage d, and acting as a truss for the shaft, being held in place by means of a
collar E on said shaft. Passing, up entirely through this hollow shaft D, is a
secord shaft F, 'extending through the upper part of the frame, having upon its
upper end a collar G, bevelled on its under side, and fitting the cup shaped socket k
formed in the upper side of the hollow nut C' secured to the upper part of the
frame d. Thus is formed a conical bearing for the upper end of the shaft F. The
lower end of the hollow shaft D, is also formed upon its interior with a cup shaped
socket similar to that described, in which fits the tapering part of a second collar G
upon the lower portion of the shaft F. The shaft F, is provided at its upper
portion near the end, with a suitable pulley 1, connected by a belt m, with the
armature shaft of the motor. Upon the lower end of said shaft is a second pulley H,
connected by suitable intermediate belts with the cutting tool. Loosely journalled
at one end upon the hollow shaft D, and prevented from vertical displacement by
collars n, are two horizontally extending arms, I, I. These arms are preferably
hollow at their outer ends for the reception of the ends of similar arms J, J,
rigidly attached at one end to a hollow shaft D similar to shaft D, by means of set
screws o, o. The ends of said shafts J, J, are adjustable in the sockets of the
arms. I, I, into which they pass, by means of a pin and a series of holes, or in any
other desirable way, thereby rendering it possible for the operator to make said
arms longer or shorter at will, to vary the amount of swing:
The hollow shaft D¹ is provided with cup shaped bearing sockets, at its upper
and lower portion, for receiving the tapering collars on the shaft F' passing through
said hollow shaft, the tapering collars and sockets being precisely similar in
construction to those heretofore described in connection with the shafts D, and F.
This shaft F carries on its lower end a double pulley p; over one portion of which
is trained the belt from the pulley on the end of the driving shaft F, and over
the other portion of which is trained the belt transmitting the power to the cutting
tool:
K, Kare two horizontal arms, loosely bearing at one end around the hollow
shaft. D and connected at their outer end by the rod or tube L, to which they are.
firmly secured by set screws or pins, as shown. These arms I, J, K, K' may be
arranged close to the surface of the tables, but it is preferred to locate them above
the head of the operator, for obvious reasons.
The lower arm K¹ is provided with a curved downward extension 7, supporting a
bent bracket M, through which passes an adjustable shaft N.. This shaft has
keyed to it, two conical shaped ears which afford bearings for it on the upper and
lower sides of the bracket M, and said shaft is slotted for the purpose of enabling
the operator to raise or lower it at will to accommodate any thickness of material
it is desired to cut. O is a tool chuck supported at the lower end of said shaft N
in which may be fitted a drill; engraving tool, or any other cutting apparatus, and
it will of course be understood that a cloth cutting or other machine may be driven
by the shaft N, by being connected at the lower end.
Carried by the shaft are two. pulleys r, r, the pulley r, being loose thereon, and
the pulley, being fixed to the shaft... These pulleys are adapted to be connected
by a suitable belts, with the pulley on the lower end of the shaft F', thus affording
the last of the chain of driving connections between the motor and the tool
shaft N. I. provide a belt shifter t; of suitable construction for shifting the
belts, from the fixed to the loose pulley in order to transmit power to the tool
or not.
