PROVISIONAL SPECIFICATION.
Improvements in Machines known in the Bobbin and Carriage
Trade as Sweswas or Grooving Machines.
WILLIAM WALKER Bobbin and Carriage Manufacturer Scotholme Works, Hyson
Green Nottingham do hereby declare the nature of this invention to be
follows:-
as
This Invention has for its object improvements in Sweswas or Grooving Machines,
as used in the Manufacture of Carriages for Lace Machines.
In carrying out my invention the Improvements to the aforesaid Machines are as
follows (viz.):
1st. The use of a sliding Bed or Table working on the Leaver.
2nd. The use of a sliding Center Axel causing the Leaver itself to slide.
3rd. The use of a sliding, or moveable Tool Box, or Holder.
Each of the above to be actuated by a Cam and Counter Cam, or Leaver motion,
whereby two or more Circles, or sections of Circles, may be obtained for cutting or
Grooving Carriages as used in Lace Machines.
Now in such Machines as hitherto constructed the Bed or Table is rigidly screwed
down to the Leaver, giving a set or decided circle.
According to my Invention, I make use of the aforesaid Sliding Bed or Table
working on the Leaver, or the sliding Center Axel, causing the Leaver itself to slide,
or a sliding or moveable Tool Box or Holder, each of the above to be actuated by a
Can and Counter Cam, or Leaver Motion, whereby two or more Circles or sections of
Circles may be obtained.

Improvements in Machines known in the Bobbin and Carriage
Trade as Sweswas or Grooving Machines.
WILLIAM WALKER, Bobbin and Carriage Manufacturer Scotholine Works, Hyson
Green, Nottingham, 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 :-
My Invention of improvements in the arrangement and construction of Sweswas
or Grooving Machines, refers principally to the use of a sliding bed or table working
on the Lever. Another part of my Invention relates to the use of a sliding center
axle, causing the Lever itself to slide.
A third part of my invention refers to the use of a sliding or movable tool box or
holder each of the above to be actuated by a cam and counter-cam or Lever Motion,
whereby two or more circles, or sections of circles may be obtained, for cutting or
grooving Carriages, as used in Lace Machines.
My invention is specially applicable for grooving carriages of the kind described in
Specification No 6763 A D 1888

page_text: The bed or plate on which the Carriages are placed for cutting or grooving is
screwed on to the moving bed or table B which passes under the tool. Into this bed
or plate on which the carriages are placed, I screw a pin or stud, and the bed or
table B being actuated by the cam and countercam D) causes this pin or stud to come
in contact with the Tool Box A A causing it to move as it is passing round the extra
section of the circle on the carriage.
Or the Tool Box, or Holder, may be moved at will by the man working the
Machine.
Fig. 2 represents the plan of my Improved Sweswa showing the sliding Bed or
Table B, also the sliding center axle e, also the cam and countercam D. D. to actuate
the same either seperately or togeather when at work.
Fig. 3 shows plan of Lever with sliding Bed or Table B.
Fig. 4 shows plan of Lever with sliding center axle C. and the Truck E. which
works between the cam and countercam DD, causing the slides to move as desired,
whereby two or more circles or sections of circles may be obtained.
Fig. 5. "sheet 2" represents the plan of the Lever with the Bed or plate Fon
which the carriages are placed for cutting or grooving screwed on to the sliding
Table B.
Into the Plate F. I screw a Pin or Stud G and the Bed or Table B being actuated
by the Cam and Countercam D. D. causes this Pin or Stud G to come in contact with
the Pin or Stud H which is screwed on to the moveable Tool Box A A causing it to
move so as to keep the Tool in a cutting position while travelling round the extra
section of the circle on the Carriage.
L represents the slot in Tool Box into which the Tool is placed when at work.
The Pin or Stud G which actuates the Tool box A. A. by coming in contact with
the Pin or Stud H is of an indefinite size or shape which may be altered as desired
according to the various sizes and shapes of Carriages that are required, so that the
Tool may be put into any desired position when at work.
Fig. 6 represents the section of moveable Tool Box or holder A A showing the Pin
or Stud G which is screwed into the Bed or Plate F also the Pin or Stud H which is
screwed on to the moveable Tool Box A A also handle K which is screwed into the
Tool Box A A by, which the same may be moved at will by the man working the
Machine.
Fig. represents the elevation of Moveable Tool Box A A showing the Pin or
Stud H also the handle K both of which are screwed to the Moveable Tool Box A A.
Having now particularly described and ascertained the nature of my Inven-
tion, and in what manner the same is to be performed, I declare that what 1
claim is.
1. The application of a sliding bed or Table working on the Lever.
2. The application of a sliding Center Axle causing the Lever itself to slide.
3. The application of a Moveable Tool Box or holder, whereby it may be revolved
or partially revolved as desired each of the above to be actuated by a cam and
countercam or lever motion, whereby two or more circles or sections of circles
may be obtained as desired, for cutting or grooving Carriages, as used in Lace
Machines, as herein before described.
Dated this Twentysixth day of July 1889.
