PROVISIONAL SPECIFICATION.
A New Apparatus for Securing "Garnett Wire" to the Periphery of
Cylinders.
I, JOHN HENRY LEATHER, of Wharf Works, Cleckheaton, in the County of York,
Machine Maker, do hereby declare the nature of this invention to be as follows:-
The object of this invention is to construct a portable apparatus capable of being
fitted to the frame of a waste opening or other suitable machine, and so arranged
that, the peripheries of rollers may be recovered with new saw-toothed wire, in some
cases without having to remove the rollers from the machine, and in others, where
the usual working position of the rollers is unsuitable, to įremove and recover them
without having to use a lathe, or other machine requiring a master screw for operating
the sliding saddle.
I accomplish my object by forming and securing to the machine frame, a light
gauntry of suitable length, somewhat similar in section to that of a slide lathe, on
which I mount a saddle fitted with a compound rest. To the said rest, I fix a suitable
support prepared for receiving a runner cut with a number of annular grooves of the
same pitch as the spiral groove or thread in the periphery of the cylinder, the grooved
runner being brought into tight contact with the roller, the projecting rings of the
runner entering the spiral groove or thread, so that on the roller rotating, the
saddle is caused to slide on the gauntry at a speed in accordance with the pitch of
the spiral groove or thread cut in the roller, the saw-toothed wire being inserted
into the groove or thread, and secured therein by milling runners in the same
manner as when a master screw is used for operating the saddle.

A New Apparatus for Securing "Garnett Wire" to the Periphery of
Cylinders.
I, JOHN HENRY LEATHER, of Wharf Works, Cleckheaton, in the County of York,
Machine Maker, 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 :-
:

The object of this invention is to construct a portable apparatus capable of being
fitted to the frame of waste opening or analogous machines and so arranged that,
the peripheries of rollers may be recovered with saw-toothed wire, in some cases
without having to remove the rollers from the machine and in others, where the
usual working position of the rollers is unsuitable, to remove and recover them
without having to use a lathe or other machine requiring a master screw
for
operating the sliding saddle and consists in constructing a light gauntry of
suitable length on which is mounted a saddle and compound rest, prepared for
carrying a runner having a number of annular grooves of the same pitch as the
spiral groove or thread cut in the periphery of the cylinder or roller, which when
brought into contact with the threads of the rotating cylinder or roller, causes the
saddle and compound rest to slide along the gauntry at a speed corresponding with
the pitch of the groove or thread cut in the cylinder or roller; the saw-toothed wire
being inserted and secured in the usual manner.
1 will now proceed to describe my invention more in detail by aid of the accom-
panying drawings in which Fig. 1. represents a side view of an apparatus showing
how my improvement may be carried into effect. Fig. 2. is a front view. Fig. 3. a
detail side view of a compound rest suitable for carrying my invention into effect.
Fig. 4. a plan. Fig. 5. a front view, and Fig. 6. an enlarged plan detail of a
runner constructed according to my invention.
The gauntry A. is of light section, and of sufficient length to extend across a
"Garnett" waste opening or analogous machine, and is shown as secured to an
independent frame B. on which is mounted a cylinder or roller R. having threads
cut on the circumference for its entire width. Motion is imparted to the cylinder or
roller R. by a pulley C. and pinion D. mounted on a stud; the pinion gearing
into a wheel E. secured on the cylinder or roller R. shaft or axle.
To the gauntry A. no longitudinal screw, rack, or other gear is attached for
operating or in any way connecting the saddle or sliding base F. of the compound
rest with the gauntry; the sliding motion to the saddle and rest being imparted in
a novel manner as hereinafter described.
The compound rest mounted on the saddle F. is provided in the centre with an
upward projecting flange F and on each side of the same is mounted two indepen-
dent rests G. and H. each rest being operated in the direction of the length of
the gauntry by the respective screws J. and J¹ fitted thereto in the usual manner :
the whole of the apparatus above the saddle or sliding base F. being operated in the
direction to and from the cylinder or roller R. by a screw K. mounted and
constructed similar to those fitted to slide rests of ordinary turning lathes.

page_text: Each independent rest G. and H. and the upper portion of the centre plate or
flange F is provided with sliding projections L. M. and N. respectively, each being
operated by its respective screw P. and held in position by a supplementary screw S.
or clamp T.
To the sliding projection L. is mounted a runner U. cut with a number of annular
grooves of the same pitch as the spiral groove or thread cut in the periphery of the
cylinder or roller R. the projecting rings of the runner entering the spaces in the
spiral groove or thread, and held therein against the cylinder or roller R. by the
operating screw P. and supplementary screw S., so that, on the cylinder or roller R.
rotating, the saddle and compound rest are caused to slide on the gauntry A. at a
speed in accordance with the pitch of the spiral groove or thread cut on the cylinder
or roller R.; the saw-toothed wire being inserted in the groove or thread, and
secured therein by milling runners carried by the sliding projections N. and M. in
the same manner as when a "master screw is used in combination with the gauntry
and compound rest.

On the runner U. arriving near the termination of the thread or groove in the
cylinder or roller R. it is withdrawn from the groove and a similar runner placed in
the projection or runner holder M. which on being operated by its screw P. so as to
engage with the spaces or spiral groove between the "Garnett wire," the saddle is
traversed by the cylinder or roller R. in a similar manner as before described,
thereby enabling the saddle to be moved the remainder of the distance required for
completing the insertion of the said wire in the grooves or threads towards and at the
termination of the cylinder or roller.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performert, I declare that what I
claim is :-
(1). The hereinbefore described method of operating the saddle of a slide rest'
the essential novelty consisting in mounting on a said rest or saddle, a runner having
one or more grooves suitable for the pitch of the screw thread cut on the periphery
of the cylinder or roller R. to be clothed, the whole being arranged substantially in
the manner as shown and described.
(2). A runner U. combined with a slide rest or saddle for the purpose hereinbefore
set forth.
