PROVISIONAL SPECIFICATION.
Machinery for Making Clips or Staples and analogous Articles.
I, THOMAS WILLIAM SHEFFIELD, of Laurel Bank, Charlotte Road, Egremont,
in the County of Chester, Engineer, do hereby declare the nature of this invention
to be as follows:-
The articles, which it is the object of my invention to produce, are those
generally termed clips, and are in the form, when viewed from one edge, of an.
arch with outwardly extended feet on either side, and they are made from thin
brass, iron, or other suitable metal. These articles or clips are useful for
securing pipes, rods, wires, and the like to surfaces; they are however also
applicable for other uses and may serve as bolt-staples, or for any other purpose
for which they may be useful.
According to my invention the articles are produced from thin metal by dies,
punches, and cutters, and a corresponding anvil with a gap to receive the pressed
out portion, and apertures to receive the punched out portions and to allow the
head of the punches to enter and which also allows the cutters to pass.
The dies, punches, and cutters, are so secured by devices or means as to be
readily applied or removed. They are mounted on a head plate or block, which
receives motion in the operation of the machine, by a screw worked by hand or
power, or by other means worked by hand or machinery, the die being removable
or changeable, so that for different sizes, different dies may be readily applied,
and used; whilst the cutters and punches are adjustable and removable by suitable
screws or studs, and they may be held in position by suitable set screws or
equivalent devices. The parts which hold the punches and cutters and also
the dies at their ends by dovetail or like formation-are adapted to slide in the
holding block above specified.
The anvil may be provided on each side with guards.
The parts above specified, are mounted in a suitable frame, the anvil being
fixed, and the die, punches, and cutters, sliding up and down, or to and fro, in
said frame, they being operated as above stated by hand or artificial power.

COMPLETE SPECIFICATION.
Machinery for Making Clips or Staples and analogous Articles.
I, THOMAS WILLIAM SHEFFIELD, of Laurel Bank, Charlotte Road, Egremont,
in the County of Chester, 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 articles, which it is the object of my invention to produce, are those
generally termed clips, and are in the form, when viewed from one edge, of an
arch with outwardly extended feet on either side, and they are made from thin
brass, iron, or other suitable metal. These articles or clips are useful for
securing pipes, rods, wires, and the like to surfaces; they are however also

page_text: applicable for other uses and may serve as bolt-staples, or for any other purpose
for which they may be useful.
According to my invention the articles are produced from thin metal by dies,
punches, and cutters, and a corresponding anvil with a gap to receive the pressed
out portion, and apertures to receive the punched out portions and to allow the
head of the punches to enter and which also allows the cutters to pass.
The dies, punches, and cutters, are so secured by devices or means as to be
readily applied or removed. They are mounted on a head plate or block, which
receives motion in the operation of the machine, by a screw worked by hand or
power, or by other means worked by hand or machinery, the die being removable
or changeable, so that for different sizes, different dies may be readily applied
and used; whilst the cutters and punches are adjustable and removable by
suitable screws or studs, and they may be held in position by suitable set screws
or equivalent devices. The parts which hold the punches and cutters and also
the dies at their ends by dovetail or like formation-are adapted to slide in the
holding block above specified.
The anvil may be provided on each side with guards.
The parts above specified are mounted in a suitable frame, the anvil being
fixed, and the die, punches, and cutters, sliding up and down, or to and fro, in
said frame, they being operated as above stated by hand or artificial power.
Drawings illustrative of this invention are hereto annexed and form part of
the Specification, the machine illustrated being a hand operated one.
In these drawings,
Figure 1 is a side elevation, partly in section, of the machine, and Figure 2
is an end view.
Figures 3 and 4 are side elevation partly in section, and end view also partly
in section, shewing the upper die; and
Figures 5 and 6 are elevation and plan illustrating the clips made by the
machine.
Referring to the figures, a is a moving crosshead on the underside of which
the die and tools are fixed, said crosshead sliding in the upright side pieces
mounted on the base cand forming one therewith; and d is a screwed rod
carried by and working in a nut in the bridge piece e, the rod d being worked
up and down by the handle f.
The upper tools on the crosshead a consist of a bending die and punching and
cutting tools mounted or fixed in holders held in, but adapted to be adjusted
laterally in the crosshead. his the bending die, and it is held to the adjustable
parts holding the cutting tools, by the flanges ¹, the edges of which are inclined
in dovetail fashion as shewn. i and j are the punches and cutting off tools, respec-
tively, these being mounted in the sliding adjustable holders, designated k. The
punches are held in position by the set screws, which screw through the
side of the holder k, whilst the cutting tools j are held in the holders by the
set screws. The holders k are held in the crosshead a by the side plates or
bars a', which are grooved on the upper inner sides, in which grooves corre-
sponding projecting parts of the holders fit and slide; and the position of
these holders in the bars a¹ is secured by the side set screws a².
This con-
struction provides for different dies and tools being held in and used on the
crosshead a, for making different sizes or forms of clips or analogous articles.
For different sizes of articles different sized dies would be used, and to change
a die the screws a² are slacked back and the holders k slid outwards, where-
upon the die can be removed and another one inserted. When this is done
the holders k are slid inwards until their inner ends come up against the inclined
edges of the flanges ¹ of the die h, when the set screws are screwed up and
the holders gripped in position.
As regards the lower die, this consists of two side blocks 1, secured in the
base c by set screws in the projecting parts of the base c. These blocks
are set apart at such a distance as will admit of the metal of the bar of which

page_text: the clips are made being pressed down between them by the upper die ; and
they are provided with through holes m, which lie directly beneath the punches i,
and the outer edges of the blocks lie practically directly under the cutting
edges of the tools j. The upper face of the blocks therefore constitute anvils
on which the bars are bent, holes cut in them, and cut off end wise, in the
desired form and at the right lengths. The holes formed in them all, have
passed through them, the fastening screws or other means, and the parts cut
out by the punches, fall through the holes m in the blocks l.
As regards the construction of the lower dies, I find it is not necessary to
have a matrix for forming the underside of the clips, the blocks described being
sufficient.
In operation the band of metal of which the clips or analogous articles are
to be formed are passed in at one end through an aperture in the lower parts-
of the uprights b (these uprights being bifurcated for this purpose as shewn at
the lower parts), and fed forward a sufficient distance over and upon the anvil
blocks ; the screw d is then rotated and the dies and tools hij are thereby
brought down and the bar is first bent into the form shewn by the die and then
the holes are punched and the article cut off to the right size.
As a modification, the die and tool holder may be one piece and adapted to
be bolted on the under edge of the crosshead; and the lower dies may be
similarly made and fastened on the base. In this case these parts would be
made in different sizes for making different sized articles.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. Machinery for making clips and analogous articles, of the form or forms
substantially as herein described, wherein such articles are produced from bars
or plates, that is to say, bent into the form required, provided with holes for
fasteners, and cut off simultaneously by means, arranged, constructed and adapted
to operate substantially as herein set forth.
2. In machinery for making clips and analogous articles, the construction of
tools holding devices and dies substantially as herein set forth more particularly
with reference to Figures 3 and 4 of the drawings.
