PROVISIONAL SPECIFICATION.
Improvements in Machinery for Making Certain Card-board and
other similar Boxes.
I, JAMES JOWETT, of Chester Street, Horton Lane, Bradford, in the County
of York, Box Maker, do hereby declare the nature of this invention to be as
follows
--
This invention relates to improvements in machinery for making that type of
card-board and other similar boxes in which a number of holes require punching in
the sides to enable them to be laced or otherwise connected together. The object
of this invention is to facilitate the formation of these holes in their proper relative
position.
For this purpose I employ one or more punching heads mounted upon a suitable
bed and adjustable in relation to each other. The punches may be operated by
arms or levers operated by eccentrics or their equivalent mounted upon a shaft
driven by a suitable clutch brought into gear by a pedal lever or the like. The
points of the punches are normally enclosed by a spring bar or sheath which is
adapted to give under pressure on the card-board or the like and the punches
protruding therefrom pierce the card-board. This arrangement besides holding the
card-board firmly prevents anything adhering to the points of the punches and is
applicable to any multiple card-board punching head.
Adjustable fences or guides are provided to regulate the position of the
card-board being punched to enable it to be brought accurately to position.

Improvements in Machinery for Making Certain Card-board and
other similar Boxes.
I, JAMES JOWETT, of Chester Street, Horton Lane, Bradford, in the County
of York, Box 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 :-
This invention relates to improvements in machinery for making that type of
card-board and other similar boxes in which a number of holes require punching
in the sides to enable them to be laced or otherwise connected together. The
object of this invention is to facilitate the formation of these holes in their proper
relative position.
For this purpose I employ one or more punching heads mounted upon a suitable
bed and adjustable in relation to each other. The punches may be operated by
arms or levers operated by eccentrics or their equivalent mounted upon a shaft

points of the punches are normally enclosed by a spring bar or sheath which is
adapted to give under pressure on the card-board or the like and the punches
protruding therefrom pierce the card-board. This arrangement besides holding
the card-board firmly prevents anything adhering to the points of the punches and
is applicable to any multiple card-board punching bead.
Adjustable fences or guides are provided to regulate the position of the card-
board being punched to enable it to be brought accurately to position.
Reference is to be had to the accompanying sheet of drawings forming a part of this
Specification, in which similar letters of reference indicate corresponding parts in
each of the figures.
Figure 1, represents an elevation of my improved machine.
Figure 2, represents an end view, and Figure 3, a plan view of the same.
Figure 4, represents a front view on a larger scale of one of the punching heads,
and Figure 5, is a side view of the same.
The bed or gantry A is supported on standards A2 and the spindle B is fixed in
the standards A3 and A* bolted on the top of the bed. A driving pulley B₁ and
fly wheel B rigidly connected together are loosely mounted on the spindle B. The
clutch B is also mounted on the spindle and the pin B5 of the clutch passes through
a hole through the said pulley and fly wheel and by being moved longitudinally in
the direction of the arrow Figure 1 its end engages a hole in the clutch disc B
rigidly secured to the toothed wheel B' thus causing the latter to revolve with the
driving pulley on the spindle. The clutch lever C mounted on the stud C² is
connected to the pedal lever C3 by the connecting bar C and is so arranged that
when the pedal lever C³ is depressed the clutch pin is moved longitudinally into
gear with the clutch disc B. When the pedal lever is released the spiral
spring stretched between the bar C and the gantry raises the pedal and
bar and by thus moving the clutch lever disengages the pin B' from the
clutch disc Bº.
The toothed wheel B' is in gear with the toothed wheel D on the eccentric
shaft D which shaft is mounted parallel to the bed A in bearings D³ formed in
the punching heads E, E² and E³. The shaft D2 also has a bearing in the
standard A and a keyway D' is formed along it.. The three eccentrics F mounted
on this shaft are provided with keys fitting the keyway D in such a manner that
they revolve with the shaft but are free to move longitudinally thereon.
The
heads E, E and E³ are arranged similar to the poppet head of a lathe so that they
may be adjusted in relation to each other along the bed A and they are each
provided with a vertical slide e, e² and e³. These slides are raised up and brought
down during each revolution of the shaft D2 by means of the arms H pivoted on
the fixed pin H2 at the back of each head and having each an opening H³ embracing
one of the eccentrics, and their other ends engage the holes et formed in the vertical
slides.
The punches i are fixed in the bottom of the vertical slides and pass into holes
formed through the bolsters E. The points of the punches are enclosed by the
spring bars J connected by the slots o formed in their lugs n, n and n³, n² to
the studs projecting from both sides of the vertical slides. The bars J have
holes formed through them for the punches i to pass through and the spiral
springs a mounted between the underside of the vertical slides and the top of the
bars tend to keep the bars down below the points of the punches. But when
the slides descend the bars J on reaching the bolsters E are prevented from
further downward movement consequently the further movement of the vertical
slides cause the punches to protrude and pass through the card-board on the
bolsters and more or less into the holes into the bolsters. Then when the vertical
slides ascend the springs force the bars J away from the bottom of the slides to
the limit allowed by the slots o.
Adjustable fences K fixed by the wing nuts K' are provided on the heads to
determine the distance the card-board is put under the punches.

page_text: 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 combination with a machine having two or more heads for punching
card-board or the like, of a clutch device operated by a pedal lever, adapted to
bring the punching heads into operation, substantially as herein shown and
described.
2. The combination with two or more heads adjustable in relation to each
other for punching card board or the like, of a shaft mounted in bearings formed
in such heads, eccentrics mounted on said shaft adapted to operate arms pivoted
in said beads and arranged to operate vertical slides carrying the punches,
substantially as herein shown and described.
3. The combination with the slide of a punching head in which two or more
punches are mounted for punching card-board or the like, of a spring bar J
formed and arranged substantially as herein shown and described and illustrated in
the accompanying drawings.
