Complete Specification Accepted, 8th Jan., 1889
I. DANIEL SMITH, Junior, of Raglan Street, Wolverhampton in the County of
Stafford, Mechanical Engineer, do hereby declare the naturo of this invention to be as
follows:-
This invention has for its object to construct a simple machine for performing the
operations named in the title.
This invention consists in the construction of the moulding slide so as to make it in
addition to moulding and gripping, available in combination with the lower moulding
dio for the purpose of edging a sheet; such moulding die in combination with other
tools to be capable of subsequently curling and moulding or folding a sheet if desired;
and further for feeding in lengths of wire if used in the process of wiring. This
invention will be readily understood from the following description.
On the front of the moulding slide I form a chamber or case containing a bar
preferably of hardened steel. Bolts pass through slot holes in this bar, such bolts
being for the purpose of firmly securing the outer or front of casing to the main
moulding slide to prevent the lateral deflection of the steel bar contained therein when
being used for the purpose of edging a sheet. This steel bar has a vertical move-
ment within its casing. When it is not in use it is (if desired) retained up by
suitable springs. By a lever motion I cause a wedge to slide or an excentric to partly
rotate and force down the steel bar below the lower face of the slide carrying the
upper moulding die it is then in forul for edging a sheet. On the front edge of the
lower moulding die I form a double rebate, the upper one serving the purpose of a
gauge to place the sheet to be edged against and the lower rebate is the one into which
the steel bar forces the sheet in its descent and thereby edges it. In the case of
strong sheets I prefer to use two bars within the casing, the front one being forced
down in advance of the other by a strong spring for the purpose of gripping the
sheet securely on to the lower die and preventing the sheet from being drawn from
the side nearest the operator, and also ensure its being drawn from off the rebate

page_text: After the sheet is edged if it is desired to mould it it is passed still further under
the moulding slide and previous to the descent of such slide the edging bar is raised
up within its casing by the lever motion withdrawing the wedge previously referred
to which also removes the downward effect of the spring on the front gripping bar if
the latter is used. The moulding slide now descends and moulds the sheet & the
curling tool is caused to advance from the back of the machine and so curl up the
sheet.
On the lower face of the moulding slide I attach a piece of steel having a knife
edge projecting toward the curling tool, so that if the curling tool is substituted by a
die having an acute-angled groove along its front edge it will be seen that by placing
the sheet already edged with its vertical edge drawn against the knife edge on the
moulding slide that the acute angle in the back die will as it advances fold down the
sheet substantially as described in the specification of my patent No. 12929 of 1886.
The curling tool may be made to curl on the one edge and to fold on the other edge
so that by simple reversal the change from curling to folding would be effected. To
effect the transition from moulded to plain work I make use of the loose movable top
die e as described in the specification of my patent No. 3959 of 1885 in combination
with the improvements herein contained.
It is my intention to use this combination of front edging arrangement and moulding
slide in combination with the parts Q and R used for giving the initial bend to the
sheet as described in my patent No. 3959 of 1885 previously referred to.
I will now describe the method of feeding the lengths of wire into the sheet previous
to its edge being curled. On the back face of the moulding slide,near and along its
lower edge I form a groove of sufficient depth to just contain a wire of the size to
be fed into the sheet. On the back of the machine near the curling tool and close to
the moulding slide, and upon suitable supports, I form an inclined table. When the
moulding slide is at the top of its stroke the lower edge of the groove therein corre-
sponds with the height of the table so that as the wires roll down the incline or table
one goes into the groove aforesaid and as the slide passes down beneath the table it
takes the wire down within its groove and on the groove passing beneath the thickness
or depth of the table the wire rolls into the partly formed curl or edge of the sheet.
That part of the slide containing the groove may be removable so as to admit of
being replaced by pieces containing other sized grooves. The recess formed for
receiving this piece may be made to serve as the recess for the projecting steel knife
used for folding.
This arrangement of feeding the wire to the sheets is described as being used with
a moulding slide but it is applicable if used with the starting slide as described in my
specification No. 3959 of 1885 before referred to, except that the wire would have to
fall into the partly curled sheet as the starting plate R rises. To effect this 1 form
a groove along the lower edge of the starting plate the lower edge of such groove
being inclined downwards. When the slide is up the wire rolls into this groove and
as it descends takes down the wire therein. 1 form a suitable groove in the edge of
the inclined table so that the wire within the starting slide rolls into this groove,
and as the starting slide rises up it allows the wire within the groove in the front edge
of the table to roll out into the partly formed curl.

page_text: and Folding Sheet Metal.
I, DANIEL SMITH, Junior, of Raglan Street, Wolverhampton in the County of
Stafford, Mechanical Engineer, do hereby declare the nature of this invention and
in what manner the same is to bo performed, to be particularly described and
ascertained in and by the following statement, reference being had to the accompanying
drawings and the letters of reference marked thereon (that is to say) :-
:1
This invention has for its object to construct a simple machine for performing the
operations named in the title and consists in the construction of the moulding slide so
as to make it in addition to moulding and gripping available in combination with tho
lower moulding die for the purpose of edging a sheet such moulding die in combination
with other tools to be capable of subsequently curling and moulding or folding a
sheet if desired, and further for the purpose of feeding in lengths of wire, if used, in
the process of wiring. This invention will be readily understood from the following
description.
Figuro 1 is a vertical section through a machine having my improvements applied
thereto. Figure 2 is a front view of the moulding slide with the edging arrangement
applied thereto and figure 3 is a section taken on line x of figure 2. Figures 2
and 3 are drawn to a smaller scale thau figure 1 for convenience of illustration. The
remaining figures will be described later on. The same letters of reference occurring
upon these views indicato corresponding parts. A is the top moulding die or slide
and B the bottom die. I form a chamber or casing a a on the front of the die A.
Within this casing is a wedge b and a steel plate c for edging down the sheet. A
plate C is bolted to the front of the casing a a by means of pins d d etc. Tho
underside of the casing a a is formed inclined (seo figure 3) and the inclined edge of
the wedge b bears thereagainst. The wedge is operated in an endway direction by
means of a key e which works in a slot in such wedge. When the key is turned
down into the position shown by figuro 2 the wedge is also in the position shown
having forced down the bar c which thus becomes solid with the die A. The
mechanism is now in position for edging a sheet. ff are rabates in the die B (see
figure 1) the upper one f¹ answering the purpose of a gauge to place the sheet to be
edged against and the lower rabate fis the one into which the bar c forces down the
sheet in its descent. The operation of the edging is as follows:-The sheet is placed
against the gauge f¹ and the wedge and plate are in the position shewn by figure 1
the die A now descends and the bar c forces down the sheet into the rabato f and
thereby edges it.
After the sheet is edged if it is desired to fold such edge the key e is turned over
in the opposite direction and this slides the wedge b along and leaves a space between
the underside of the wedge and the top side of the steel bar c, and thus as the die A
descends in the subsequent folding the bar c does not mark the sheet but simply slides

page_text: up within the casing the holes through which the lower pins pass being slotted for
this purpose. These pins d d also serve the purpose of securing the lower edge of
the plate c firmly to the lower edge of the die A thereby preventing any deflection
taking place in the plate c.
Laccomplish the folding as follows. I secure a piece of steel g to the underside of
the die A (see figure 1). This steel projects towards the back of the machine to a
knife edge as shown and I also place a folding tool C in the position shewn. The
sheet already edged is placed up against the folding tool C' and the dio A descends
but such die is adjusted so that it does not grip the sheet and as the folding tool
advances it pushes the edged sheet against the knife edge 9 and thereby folds the
edge over the knife edge as will be readily understood. is one of a number of set
pins used to adjust the tool C³.
Figure 4 is a corresponding view to figure 1 but shows the knife edge g removed
from the moulding slide A and the folding tool replaced by a curling tool also
lettered and the part of the bottom die B in which the rabates ff are formed I
remove and replace by a part shaped as shown. The bar c is also removed and
replaced by a bar having its back edge rounded as shewn. The operation will be
readily understood from the following description. The sheet to be curled is placed
against the rabate and as the die A descends the steel bar e forces down the sheet
and thus gives an initial bend or curl to the edge thereof. The partly curled shoot is
now placed against the curled part of the tool & which acts as a gauge and the die A
descends and tightly grips the sheet whilst the curling tool advances and completely
curls over the edge thereof. The tool ( may be made to curl on one side and fold on
the other if desired. I make use of several of the parts described in the specification
of my patent 3959 of 1885 in connection with my present invention for instance the
dies A and B and the curling tool Care substantially the same and if it is desired to
mould a sheet I make use of the loose movable top die lettered c described in my said
specification in combination with my present improvements.
Figures 5 and 6 (sheet 3) show a simple modification of edging and folding sheets.
Sufficient only of the machine is shewn to make the invention clear. D is the
edging slide which has a downwardly projecting leg for the purpose of edging the
sheet. F is a block for the purpose of gripping the sheet to be operated upon. sis
one of a number of springs above such block. G is the folding tool. is a piece of
steel projecting to a knife edge to fold the sheet over and H is an opening in the bed
of the machine extending the whole length thereof and a block I fits therein. The
block I is kept in the position shewn by figure 5 by means of springs one of which is
shewn at k. This block is for the purpose of supporting the knife edge; whilst
the sheet is being edged. J is a longitudinal spindle fixed at each end of the machine.
Upon this spindle are keyed 2, 3 or more strips of iron or steel to act as a gauge.
One of these pieces is shown at 7. It will readily be seen that the gauge may be
adjusted by simply turning the spindle J round which is shaped at one end to receive
a spanner. Grooves or slits are cut in the leg i and in the folding tool G in position
where the strips are fixed. The operation of the machine is as follows:-The sheet
to be edged is placed against the gauge and the edging slide D and block F descend
together the block F yields against the springs and grips the sheet whilst the leg i
edges down the sheet as shewn by figure 5. If the sheet thus edged is desired to be
folded the folding tool G is caused to advance and folds such sheet over the knife
edge the parts then being in the position shewn by figure 6. The block I yields
against the springs so as to allow the tool G to fold over the edge of the sheet and
such tool has a forwardly projecting part m which as the tool advances pushes the
block I out of the way and allows the sheet to bo folded over the knife edge.
I may use the front edging arrangement and moulding slide as described and
shown by figures 1, 2, and 3 in combination with the parts Q, R, H and X used for
moulding and curling sheets as described in the specification of my patent before
referred to.
I will now describe the method of feeding the lengths of wire into the sheet
previous to its edge being curled. This part of my invention is clearly shown by

figures 7 and 8 sheet 4 of the accompanying drawings. I make use of the
fingers e e¹ etc, and finger bar H' described in the specification of my patent before.
referred to. I have shown the fingers and bar on the drawings herewith & such
fingers are lettered r. Parts corresponding to parts on figures 1, 2, 3 and 4 are
similarly lettered. I form a groove n along the lower back edge of the die A of
sufficient size to contain a wire. I place an inclined table o in the position shewn
and it will be seen that when the slide A is at the top of its stroke one of the
wires will roll into the groove n. The front of the table is shaped as shewn so that
as the dio A descends with the wire in the groove n such wire is prevented from
falling out until it passes below the depth of the table. The front of the table is
grooved to allow the fingers- to-pass through and as the fingers come opposite the
grooves the springs at the back of the finger bar force such bar and fingers forward.
into the position shewn by figure 8 and they thus keep the wire from rolling away!
whilst being curled up within the sheet. For the purpose of bringing the fingers
back from the position shewn by figure 8 to the position shewn by figure 7 I form a
projection p on each end of the framing of the machine. These projections have
inclined faces as shewn. I cut away each end of the finger bar to the same taper as
the projections and as the dio A with the finger bar. thereon rises the inclined faces
on the finger bar catch against the inclined faces of the stops and draw the fingers
back as will be readily understood. That part of the die A containing the groove n
may be removable so as to admit of being replaced by pieces containing different
sized grooves to suit different sizes of wiro.
This arrangement of feeding the wire to the sheets is described as being used with
a moulding slide but it is applicable if used with the starting slido as described in the
specification of my patent before referred to. This application will be readily under-
stood on reference to figure 9 sheet 3 of the accompanying drawings. Parts
corresponding to parts in figures 7 and S are similarly lettered. The starting slido is
lettered K. The top of the table o is level with the underside of the groove n when
the die A is at the top of its stroke and a wire rolls into the groove as shown. I form
a groove in the edge of the table o and as the starting slide K descends the wire
rolls out of the groove n into the groove as such grooves come opposite to each
other. The wire is retained in the groove q until the starting plato rises again and
the wire then rolls out into the partly formed curl. I make the lower edge of the
groove n inclined as shown so as to ensure that the wire will roll out therefrom into
the groove
