PROVISIONAL SPECIFICATION.
Improvements in Gearing for Transmitting Motion and Power.
I, JOHN JOSEPH GARRATT 429 Oldbury Road Smethwick Turner and
Toolmaker do hereby declare the nature of this invention to be as follows:-
The invention is an improved method for transmitting driving power and motion.
The inventor purposes taking two toothless wheels, or in some cases, shafts, (any
of which may be of any dimensions), and upon one of these wheels or shafts, he
intends fixing a number of balls (which will also vary in size and number, as
required). In the second wheel or shaft he purposes making a number of holes,
(which will also vary in size and number as required to suit the balls).
These wheels or shafts, when in their working position will be so placed that as
one of them revolves, the balls will gear into the holes, thus power and motion
being transmitted by means of the balls from one wheel or shaft, to another wheel
or shaft, at any angle.
Dated this 27th day of June 1895.
COMPLETE SPECIFICATION.
Improvements in Gearing for Transmitting Motion and Power.
JOHN JOSEPH GARRATT 429 Oldbury Road Smethwick Staffordshire, Turner
and General Machinist, do hereby declare the nature of this invention and in what
manuer the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
The invention is an improved method for transmitting driving power and motion.
The inventor purposes taking two or more toothless wheels, or discs, or in some
cases shafts (any of which may be of any dimensions) and upon or in one or more
of these, he intends fixing a number of balls, (which will vary in size and number
as required). In the remaining wheels, discs, or shafts, as the case may be he
purposes making a number of holes, which will also vary in size, and number, as
required.
These wheels, discs, or shafts, when in their working position will be so placed
that as oue of them revolves the balls will gear into the holes, thus power and
motion, being transmitted by means of the balls, from one wheel, disc or shaft to
another wheel disc, or shaft at any angle.
To make the invention more clearly understood I will proceed to describe its
action with the aid of the drawings herewith.
Fig. 1 shews the shafts A & B working at right angles.
Fig. 2 being a plan of same. The disc E, on shaft B, is made to receive the
balls C, which are held in their places by the plate G. The disc F, on shaft A, is
bored out on its periphery to receive the balls C, as shewn at D, at suitable
distances, to correspond with the pitch of the said balls in disc E. Supposing the
shaft B, and disc E, to be the driver, and the balls C, to be geared into cup shaped-
receptacles as at D in Fig. 2. When the said shaft B, with disc E is revolved, the
77

page_text: balls C, will enter the cup-shaped receptacle D, and so revolve the disc F, &
shaft A.
Figs. 3 & 4 shews the invention geared on to shafts working parallel to each
other, the same distinctive letters being used to describe its action.
Figs. 5 & 6 shews the invention as applied to bevel gearing.
Fig. 7 as applied for driving shafts in line thereby dispensing with ordinary
clutches, or couplings, as shewn at H, where the shafts being disconnected the
discs E, & F, are out of gear, and as shewn at I where the said discs E & F, are in
gear, and consequently the shafts are connected.
Having fully described my invention in reference to Figs. 1. 2. 3. 4. 5. 6. 7. I do
not wish to he confined thereto, as there are several other ways in which my gearing
can be applied.
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 ;
3t. The use of balls, placed so as to operate as gearing for transmitting power
and motion, as set forth in Figs. 1. 2. 3. 4. or any other modification thereof.
2nd. The use of balls operating into cup shaped receptacles, for bevel or such like
gearing as set forth in Figs. 5 & 6.
3rd. The application of such gearing to be used for driving shafts in line, as set
forth in Fig. 7.
4th. The general arrangement & construction of gearing as set forth in
Figs. 1. 2. 3. 4. 5. 6. 7. for the purposes described.
Dated this 26th day of March 1896.
