Improvements in or relating to the Manufacture of Grilled Work
and so called Venetian Iron Work.
A communication by WILLIAM RAIMOND BAIRD, of 271, Broadway, New York,
in the County and State of New York, United States of America, Civil and
Mechanical Engineer.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for Foreign
Patent Solicitors, 6, Lord Street, Liverpool and 6, Bank Street, Manchester, both
in the County of Lancaster, 118, New Street, Birmingham, in the County of
Warwick, and 322, High Holborn, in the County of Middlesex, Civil 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 fol-
lowing statement ;-
This invention relates to tools for cutting and binding metal strips. Its object
is to make it easy to bind together a plurality of pieces of band iron in the manu-
facture of grilled work and so called Venetian iron work, that is, iron work in
which the frames have the spaces they enclose filled with forms of curved flexible
metal, usually of wrought iron and to make a simple single tool to take the place
of the several devices usually employed in this class of work.
In the drawings in which the same letters refer to the same parts in all of the
figures,
Figure 1, is a side elevation of this device with a portion of the base plate in
partial section and with the end of the lever removed. Figure 2, is an elevation
of the other side of a portion of the tool showing the location of the knife.
Figure 3, is an enlarged detail view of the bifurcated end of the actuating lever.
Figure 4, is a top plan view of the upper jaw of the binder. Figure 5, is a side
view of the upper portion of the bar showing the collar of the upper jaw in section.
Figure 6, is a perspective view of the upper portion of the bar. Figure 7, is
a detached perspective view of the clutch of the upper jaw. Figure 8, is an
enlarged side view showing the relative positions of the jaw, the iron bands, and
the binder before action; and Figure 9, is a similar view showing their position
after action.
In the drawings A is a standard consisting of a bed-plate a supporting a guide
head a and a base plate a¹ united by a vertical plate a¹. The base plate a¹
is provided with a central vertical socket s adapted to receive a coiled spring s¹.
The guide head all is provided with a central vertical slot adapted to receive the
upper portion of the bar R which reciprocates through it.
The bar R is composed of four parts, an upper part r¹ of circular section and
slotted at g, a lower part 11 which may be of any shape and around which is
coiled the spring s¹, and two central parts, the upper one of which r¹ is square
or rectangular in section and about the width of the diameter of the part ŕ and
the lower one of which may be of any shape in section but which must be
of sufficient size to prevent its passage upward through the slot in the guide
head a", and the lowermost portion of which affords a place of abutment for
the upper end of the spring s¹. The bar R is provided with lugs P and P¹ the

page_text: purposes of which will presently appear. To each side of the vertical plate all
is pivotally secured a lever L which is bifurcated and slotted at 7 and to admit
of the passage of the lugs P and P. The outer extremity of the lever is not
shown in the drawings. As will readily be seen the upward or downward motion
of the lever on its pivot will actuate the lugs P and P and through them com-
municate a reciprocating movement to the bar R, which is normally held in place
by the action of the spring s¹. The lever L is recessed at the inner side of one of
its arms, and in this recess is secured a knife edge K by a screw B or other suitable
means. The vertical platea is also recessed and adapted to receive a plate or
edge which is secured in place therein by a screw C or other suitable means.
These two edges K and k the former on the pivoted lever L and the latter' on
the standard A form together a powerful pair of shears. The upper portion of
the bar R is provided with a detachable member D provided with a collar d
adapted to slip over the bar R and a lower projection d which forms a jaw and
between the inner face of which d¹¹ and the bar is formed a pocket m. Similarly
a projection E having an inner face e forms with the bar another pocket m'.
The means which is employed for securing the member D in place on the bar R
is a little friction-catch F loosely pivoted on top of the member at f. This
is curved at f¹ and may with the exertion of a little force be moved over a
little projecting stud normally pressed upward by a spring confined in a socket
in the member D. The bar R is recessed at g and adapted to receive the end I
of the catch, thus preventing its upward movement and securing the member D
firmly in place. When it is desired to remove the member D the catch Fis
pressed over the stud the catch is thrown out of the recess y and the collar d
readily slides upward and off of the bar.
The method of using this improved tool is as follows: Supposing that it is
desired to unite two or more bands as N by the binder O. The binders are made
already bent into "U" shaped pieces and are of different sizes to admit of a
different number of bands being secured together.
The bands N are placed in close contact and are placed within the binder Q
so as to be partly embraced thereby. The parts thus arranged are placed on
the upper edge of the jaw E so that that portion oll of the binder O rests almost
or quite against the bar R. The lever L is then depressed. This exerts a down-
ward pull upon the bar R which carries with the member D and jaw d¹ until
the latter is in contact with one leg o of the binder O. The downward pressure
upon the lever being continued the outer part of the leg o is first bent over as
shown in Figure 9, so as to partly encircle the bands N and bind them closely
together. Further pressure being exerted the leg o' of the binder O is bent upward
against the inner edge of the jaw E and also made to partly encircle the bands N
from their lower side. At the same time both bands and binder are tightly
wedged into the double pocket formed between the jaws and the bar. The lever
now being released the reaction of the spring causes the bar R to fly upward
and the frictional contact between the jaw and the bands usually is sufficient
to at once pull the bands out of the pocket. Should it stick, however, a slight
pressure of the catch F is sufficient to release the jaw d¹ from the bar R and thus 4
render the removal of the bands and binder easy. By means of shears formed by
the pivoted lever provided with a knife edge K and the similar knife edge set
into the vertical plate a¹, the bands to be united together may be cut any
desired length and at any desired angle.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me
by my foreign correspondent, I declare that what I claim is:-
1. In a binding tool the combination with a bar of two jaws provided with
angular pockets adjoining said bar and means for bringing the jaws toward
each other.

2. The combination with a bar carrying a jaw having an angular” nocket

page_text: adjoining said bar, of another jaw also having an angular pocket adjoining said
bar and mounted on a guide head through which said bar passes.
3. The combination with a bar and means for moving the same, of two jaws
each provided with an angular pocket adjoining said bar, one detachably mounted
on said bar and the other similarly mounted on the guide for said bar.
4. In a binding tool the combination with a bar of a jaw provided with an
angular pocket adjoining said bar and means for detachably securing the jaw
to said bar.
5. In a binding tool the combination with a bar of two jaws each provided with
an angular pocket adjoining said bar, means for actuating said bar and means
for normally keeping the jaws apart when not in use.
6. The combination with a standard of a bar, two jaws each provided with an
angular pocket adjoining said bar, a lever provided with a knife edge and adapted
to actuate said bar, and a corresponding knife edge mounted on the standard."
