DANIEL SMITH Castle Iron Works Raglan Street Wolverhampton Staffordshire
Mechanical Engineer -do hereby declare the nature of this invention to be as
follows:-
The object of this invention consists mainly in constructing the lathe in such a
manner as to admit of the wiring or part wiring of the top edge of the bucket
being done more expeditiously than heretofore. In order to give effect to this
improvement I construct the lathe as usual excepting that the lathe spindle that
rotates within the headstock is allowed to slide end ways in its bearings and by a
spring (preferably under compression) the lathe spindle is forced forwards towards
the loose headstock. The lathe spindle carries a cone or mandrel that receives the
bucket, on this cone the bucket body is placed, the bucket bottom is put on and the
pallet of the loose headstock is drawn up against the bottom by a lever that is
forced downwards against a suitable incline, formed within the loose headstock.
The effect of such incline being to cause the bucket, cone and lathe spindle to
recede and allow the unwired top edge of the bucket body to come into contact
with the wiring wheel which immediately wires it, such wiring wheel being carried
by a fixture on lathe bed. The usual sliding bar (across the lathe bed) with
suitable rollers is used to manipulate the edges and secure the bottom of the bucket
on to the body part. On releasing and withdrawing the pallet of the loose head-
stock for the removal of the bucket the spring at the back of the lathe spindle
then forces the latter forward ready for the operation to be repeated. In this
arrangement the same movement of the loose headstock lever that secures the
bucket on the cone is made to effect the wiring or part wiring also, whereas in lathes
as usually constructed the wiring is done by a screw used to force
the wiring
wheel, taking considerable time. This improvement herein described can be used
in a machine horizontal as a lathe or vertically as may be desired. Since the
lathe spindle will travel say in a straight line and the work to be wired may be
taper I may fix the wiring wheel in such a manner as will follow up or conform to
the taper of the article being wired.

Improvements in Lathes used for Wiring or Part Wiring the Tops

DANIEL SMITH Castle Iron Works Raglan Street Wolverhampton Staffordshire
Mechanical Engineer, 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 consists mainly in constructing the lathe in such a
manner as to admit of the wiring or part wiring of the top edge of the bucket
being done more expeditiously than heretofore. In order to give effect to this
improvement 1 construct the lathe as usual excepting that the lathe spindle that
rotates within the headstock is allowed to slide endways in its bearings and by a

page_text: spring preferably under compression the lathe spindle is forced forwards towards
the loose headstock. The lathe spindle carries a cone or mandrel that receives the
bucket, on this cone the bucket body is placed, the bucket bottom is put on and
the pallet of the loose headstock is drawn up against the bottom by a lever that is
forced downwards against a suitable incline formed within the loose headstock, the
effect of such incline being to cause the bucket cone and lathe spindle to recede
and allow the unwired or unbent top edge of the bucket body to come into contact
with the wiring wheel which immediately curls it over, such wiring wheel being
carried by a fixture on the lathe bed. The usual sliding bar across the lathe bed
with suitable rollers is used to manipulate the edges and secure the bottom of the
bucket on to the body part. On releasing and withdrawing the pallet of the loose
headstock for the removal of the bucket the spring at the back of the lathe spindle
then forces the latter forward again, ready for the operation to be repeated. In this
arrangement great economy of time is effected because the same movement of the
loose headstock lever that holds the bottom and forces the bucket on to the cone is
made to effect the curling, wiring or part wiring, whereas in lathes as usually
constructed the curling or wiring is done by a screw used to force up the wiring
wheel, taking considerable time. This improvement herein described can be used
in a machine horizontally as a lathe or vertically as may be desired. Since the
lathe spindle will travel say in a straight line and the work to be wired may be taper
I may fix the wiring wheel in such a manner as will follow up or conform to the
taper of the article being wired. This may be accomplished to a considerable
extent by allowing the wiring or curling wheel to have lateral motion on the stud
upon which it revolves.
I will now describe this invention having reference to the accompanying
drawings. Fig. 1 Sheet 1 being an elevation of the lathe and Fig. 2 a plan of
Fig. 1. These views representing the lathe with its moving parts in their proper
relation previous to the performance of the operation of curling and wiring the
top edge of the bucket and securing the bottom on to the body part. Figs. 3 and 4
(Sheet 2) showing corresponding views of the same lathe after the operations just
mentioned are accomplished. In Fig. 1. T. T. are the stands. B. B. is the bed
part. H is the fixed headstock. P is the poppet adjustable along any part of the
bed B. C is the cross bar fixed but adjustable on the bed B. In the cross bar C
is a sliding bar a' and to this are secured the uprights d that carry the usual double
seaming rollers e. e. The manipulation of these double seaming rollers e. e. is so
well understood that further description is unnecessary. In the headstock H. k is a
cone pulley keyed on the spindle p to rotate same. The spindle p has an end
movement say of about an inch. The spring S pressing against the projecting end
of the spindle p, forces and retains the spindle p with its cone n towards the
pallet y.
The cross bar C is now adjusted and secured across the bed B so that
the rollers e. e. are in line with the juncture of the lower edge of the bucket and
its bottom part, when these have receded into the position indicated by Figs. 3
and 4 (Sheet 2). On the base piece X the swivel post V is capable of moving
through a considerable angle in a horizontal plane to conform and is secured in any
position by the nuts i. At the top of the swivel post V is another swivel part m
capable of swivelling or turning through a considerable angle in a vertical plane
and is secured in any position by the nuts u. Within the part m is a slide O
adjustable by the hand wheel and screw R that serves to carry a stud upon which
the curling or wiring roller a rotates. The object of the slide O being adjustable,
is to fix the curling or wiring wheel a, a suitable distance from the edge of the
bucket n¹. The poppet P is provided with a sliding bar f, this being round in
section. On the end of this bar is the pallet y. which is provided with hardened
steel centres that press against a corresponding centre in the end of the bar fin
order to ensure rotation of the pallet y without undue friction on the end of the
bar f
1 will now describe the method of adjusting the poppet P and wiring wheel a;
also the operation of wiring the top edge of the bucket a¹ or other receptacle

page_text: required. The bucket body being previously prepared by well known processes having
its bottom edge properly edged as at b shown by Fig. 5 (Sheet 2). The bucket
body is now put on to the cone n and its previously formed bottom part, (shown by
Fig. 6.) is placed on the end of the cone n. The poppet P is adjusted and secured
in such a position on the bed B that the pallet y presses against the bucket bottom
on the small end of the cone n when the handle w is drawn forward to about the
top of the incline Z. The handle w² is now pressed down the incline Z, this in
effect causes the handle w³, bar, pallet y, cone n and bucket thereon to recede
until the top edge of the bucket n' comes in contact with the curling roller a which
is provided with a suitable groove, this in effect, owing to the rotation of the bucket
and its cone (as indicated by the arrow r) rotates the wiring roller a and causes
the top edge of the bucket to curl outwards or inwards as desired and as determined
by the adjustment of the roller a. The amount of metal to be curled up can also be
regulated by the adjustment of the roller u, if set forward towards the cone n it is
more, but if withdrawn it will be less. This makes the wiring devise applicable
either for what is known as half curling, or complete curling known generally as
imitation wiring. In the former case for the completion of the wiring it is
customary to transfer the bucket on to what is known as a tucking machine on
which the bucket is placed, and a ring of wire laid within the partly or half curled
edge and closed therein by the tucking wheels used therefor as is well known.
From this description it will be seen that the act of or simple motion of forcing
the lever w down the incline Z not only forces the body of the bucket on to the
cone n and compresses the bucket bottom close to the end of the cone but also
curls, wires or part wires the top edge of the bucket. The effect of so much being
done by one motion of the handle is to greatly expedite or more than double the
output of the lathe when compared with the old method of a non-sliding spindle in
which the curling or part wiring was done by screwing up the hand wheel R, this
being a slow method and wasting much time.
While the bucket is still cramped
by the pallet y on to the cone n the rollers e. e. are by the hand lever W¹ readily
brought into operation. The front roller closing down the single edge of the
bucket bottom over the edge of the bucket body and the back roller bends or rolls
over the double thickness, or does what is known as double-seaming the bucket
bottom on to the bucket body.
The operations done will possibly be better understood if we refer to Figs. 3
and 4 (Sheet 2). These show the relation of the parts when they are completed.
The handle w being now forced down to the bottom of the incline Z, the pallet y
being up against the bottom of the bucket on the cone n, this and its spindle p and
spring S are forced back against the adjustable back stud and the top partly
curled or wired edge n¹ being close against the roller a. It will now be readily
understood that as the handle w³ is raised up and pushed back into its original
position shown by Figs. 1 and 2 (Sheet 1) the spring S will at once cause the
spindle p and cone n to advance. The bucket will then be readily removed and
another one substituted and all will be in order for the operation to be repeated.
The partly curled edge and the bottom secured therein will be best seen by
|Fig. 7.
The lathe herein described is shown with its spindle horizontal but if it is desire.
to build a machine to part curl the edge and secure a solid wire within such edge
as shown by Fig. 8 it is preferable to build the machine with its spindle and cone
vertical and all parts in the same relation because by doing this, gravity would
then be available to assist in keeping the wire ring down within the partly curled
edge n Fig. 7. The wire thus fixed or secured within the curl is shown in
section by Fig. 8.
In case this machine was built vertically that is to say standing up as it were on
the fixed headstock end of the bed, a base or stand part would be provided and
the legs T. T. removed. In the place of the three-speed cones k one pulley would
suffice, in combination with two back pulleys running loose upon suitable
spindles for the band to pass over to change its direction from the horizontal to

page_text: the vertical. A variable speed could then be obtained by cone pulleys on an over-
head motion. The spindle p could be balanced preferably by a stronger spring or
a weighted lever because of the greater weight of spindle p, pulleys, and bucket
cone n. The sliding bar and its parts could also be balanced by a long spring
suspended from an over-hanging bracket secured on the rear of the poppet P.
The poppet P, also the cross bar C could be suspended from chains passing over
suitable pulleys having weights to balance them, making it possible to liberate
them on the upright bed part without their falling, and the fixture X carrying the
wiring wheel a could rest on and be secured to the cone end of the headstock H say
at about the point M.
The grooves in the wiring wheels are semi-circular of a radi equal to about half
the diameter of the wire or rather more.
The scale of the accompanying drawings is approximately one-eighth full size.
Since a considerable part of the machine herein described is not new; before
proceeding to state what I claim as my invention I desire to disclaim as follows;-
Having reference to the means used for double seaming the bottom of the bucket
on to the body part, consisting of the cross bar and its slide a with its
rollers ee; also the means for wiring the top edge of the bucket consisting of the
parts X, V and m with the roller a, the latter being put into and out of operation
by means of the band wheel and screw R. Also the incline Z on or in the
poppet P acting in conjunction with the handle w and bar and pallet f and y as a
means of forcing the bucket on to the cone and holding the bucket bottom up to
same. I disclaim these for the above stated purposes as a part of my invention.
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;
1. The headstock H and spindle p being constructed so that the spindle p during
rotation will slide or recede end ways by pressure applied by the pallet y to the
cone n or bucket thereon, thereby causing the top edge n¹ of the bucket to travel
into contact with the curling wheel a and with further motion necessary to complete
the curl or wire the top edge of the bucket n' as herein described and shown having
reference to the accompanying drawings.
2. The spring S or its equivalent for the purpose of giving resistance to the
backward or end motion of the spindle p and for returning such spindle and
cone n back again to its original position as herein described and shown having
reference to the accompanying drawings.
3. The incline Z or its equivalent on or in the poppet P in conjunction with the
handle w³ and the barf and pallet y (the latter free to rotate) for the purpose of
causing the cone n and bucket thereon to recede until the top edge of the bucket n'
comes into contact with the wiring roller a. Such incline Z giving sufficient
motion to effect such curling of the edge as may be desired as herein described
and shown and having reference to the accompanying drawings.
4. The points enumerated in Claims No. 1 2 and 3 as applied to the vertical
modification herein described for the purpose of facilitating the insertion of a solid
wire ring within the top curled edge of a bucket.
