in the County aforesaid Card Master 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 further improvements in apparatus as aforesaid for which
Letters Patent No. 11,938 dated the 18th day of August 1888 were granted to the
present applicants and the object is to dispense with certain gearing and appliances
Leretofore employed and to substitute in lieu thereof a device for communicating the

According to this our present invention we dispense with the gear wheels or discs,
and teeth which are marked 8 and 10 in the Specification: of Letters Patent
No. 1193888 as aforesaid, and substitute therefor one or more spur shaped drivers,

which (when a losing motion" is desired) is keyed fast on the main axis or,shaft,
and is the first driver, the number of teeth on the disc being greater than the number
on the wheel which in this case is first driver, the boss of the latter wheel or disc
being formed with a dovetail or dovetailed recess thus forming part of a clutch so as
to be capable of being reversed and placed in gear with the clutch on the long collar
or boss.
A wheel guard or hollow boss and cam serves for altering the position of
the cup plates or discs and also the teeth formed thereon by rolling or moving the
same on the ball.
When the jack is working with the several parts in the positions
described the motion is a "losing notion" but if a "gaining motion is required
then the hall is fast on the main axis, or shaft, and the cup plates or discs are
reversed, i.e. taken off the axis or shaft and replaced the opposite way, the wheel or
disc (which was the first driver above mentioned) engaging with and forming part
of the clutch in the long collar or boss the motion is drawn from the ball which is
keved fast on the axis or shaft and becomes the first driver and the motion. is, a
gaining motion." By employing the apparatus in duplicate a double " gaining
motion" or "losing motion " is obtained.

Such being the nature and object of our said invention the following is a complete
description of same reference being made to the accompanying drawings in
which:-
Fig. 1. is a general view or elevation of the improved "jack" complete.
Fig. 2. is a plan view or a similar view to Fig. 1. but turned one fourth of a
revolution.
Fig. 3. is a longitudinal section drawn to an enlarged scale (about full size) and
shewing the whole of the parts in position.
Figs. 4. 5. 6. 7. 8 and 9 are views of the several parts drawn. separately, for the
purpose of clearly illustrating their construction.;

page_text: Fig. 10 illustrates the "jack in position and an arrangement of gear.suitable for
application of "jack" to roving and slubbing frames but such gearing does not form
any portion of this invention."
According to this.our invention we dispense with the gear wheels or discs and teeth
which are marked 8 and 10 in the Specification of Letters Patent No. 11938 of the
year 1888 and substitute in lieu thereof a series (preferably four) of. spur shaped
drivers 1 (see Fig. 9) the straight shanks or pins of which are received and enclosed
in slots, grooves or holes 2 formed in the faces of two cup plates or discs 3. 4 (see
Figs. 7 and 8) so that when the two cup plates or discs 3. 4 are in the working
position i.e. secured together by screws 5. 5 (see Fig. 3) the shanks or pins of the
drivers 1 are enclosed between the two and loosely held thereby.
In order to reduce the friction we in some cases placed in the shank or piu of the
drivers an anti friction bowl or runner 1* which is received in a cavity or recess 2
formed by the cup plates or discs 3. 4 thereby lessening friction between the drivers
and discs. The two cup plates or discs 3. 4 also enclose when screwed together, a ball
or oval shaped bearing 6 on the main axis or "jack" shaft 10 and in the ball 6 are
cut or formed a series of slots or grooves 7 corresponding to the holes 2 in the cup
plates or discs 3. 4-these slots or grooves 7. 7. receive the forked portions of the
spurs or drivers 1. Cast to and forming a part of the ball 6 is a long collar or boss 8
which is dovetailed or formed as part or half of a clutch 9.
The pins or straight shanks of the spur shaped drivers 1. 1. act as rotary drivers,
whilst the curved or forked part of the same working in the slots or grooves 7. 7.
admit of the requisite side motion or change of position of the cup plate and disc 3. 4
in relation to the main axis or jack shaft 10. On the outer face of the disc or cup
plate 8 are formned or cut teeth 11 which gear with the teeth 12 formed in the face of
a wheel or disc 13 on the inain axis or jack shaft 10. A wheel guard or hollow boss 14
and cam 15 (see Figs. 4 and 5) serves the purpose of wheel guard and also for altering
and varying the position of the cup plates or discs 3. 4. and the teeth 11 formed
thereon by rolling or moving the same on the ball or oval bearing 6, the latter forming
a surface on which the cup plates or discs 3. 4 revolve and oscillate so far as allowed
by the spur shaped drivers 1. 1. which connect the cup plates or discs 3. 4 and
bearing 6 as above described, the cam face or oblique rim 15 of the hollow boss 14
coinciding with and bearing upon the face 16 of the cup plate or disc 4 (see Fig. 3)
and so keeping the teeth 11 in gear with the teeth 12. The "jack" may be geared
up to, in any suitable manner, according to the purpose to which it is to be applied as
for example-
In Fig. 10 a driving pulley A on the main or jack shaft 10 operates the latter, and
at its other end is the twist wheel B gearing with a carrier C, latter gearing with
wheel D on top cone shaft E the bottom cone F drives the bevel gear C on the
upright shaft H and by mitre or bevel wheel J gears with a like wheel K on the
collar L of the wheel guard 14 the cam face 15 bearing on the face of the disc 4
keeps the teeth il in gear with the teeth 12 (see Fig. 3.) and on the long collar or
sleeve N¹ is a wheel M gearing with the train of wheels connected with the bobbin
wheels N.
The action is as follows:-
The main or jack shaft 10 runs at an uniform speed, and when a gaining motion is
desired the disc or wheel 3 is the first driver the oval bearing 6 being keyed fast to
the shaft 10 and the wheel 13 having 30 teeth (12) and the wheel 3 has 33 teeth (11)
thus the wheel M (see Fig. 10) will make one revolution more in 11 than the shaft, 10
when the cam 14 is stationary.
When the "jack" is working with the several parts in the positions described and
illustrated a gaining motion is obtained, but if a losing motion is required then the
ball or oval bearing 6 is loose on the main axis or jack shaft 10 and the cup plates or
discs 3. 4 are reversed i.e. taken off the shaft 10, and replaced the opposite way the
part or half of the clutch or dovetail 9 in the boss of the wheel 13 engaging with
and forming part of the clutch 9 in the long collar or boss 8 of the ball or oval
bearing 6 and the latter being loose the first driver is the wheel 13 which is keyed

page_text: fast on the shaft 10 and thus the motion is losing one in eleven-the shaft 10
making 11 revolutions while the wheel M makes 10.
It will be seen by the foregoing complete description that we have provided a "jack"
constructed of fewer parts with consequent saving in cost of manufacture less wear
and tear and requiring less driving power to operate the same. Againing motion"
or a losing motion can be obtained in various ways by changing the positions of the
several parts without in any way introdueing new mechanism or appliances and that
the shape or configuration of the parts may be altered without departing from the
invention as for instance the shape of the ball bearing 6 which instead of being made
with an outward curve might be recessed or curved inwards, and the ball or oval
bearing be on the discs or cup plates 3. 4, the shape of the spur shaped drivers 1 being
modified to accomodate themselves to the alteration or change of form.
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 :-
The general construction combination and arrangement of parts constituting the
improved jack" for purpose and as herein fully described and substantially as
illustrated by the annexed drawings.
