Figures 4 and 5 show respectively a side view and plan of portions of our improved
apparatus each severally refered to hereafter, and on sheets 6 and 7 are shown in plan

Our improved apparatus is applicable to what are known as the piano jacquard card
punching machines. But we dispense with the whole of the usual lever wards and the
stop rods, or finger rods which they operated and instead thereof we substitute our
improved series of apparatus.
The first series of apparatus consists of the following parts.
To the lower fixed bed of a piano punching machine of the usual construction through
which the card to be punched is passed we secure a box A provided with a pair of brass
sleys A' both at the back and front, in these sleys selecting plates A' slide horizontally,
the sleys shown at Figure 3 will receive forty selecting plates, but a greater number
may be employed in one box if made proportionally deeper according to the number
of plates required, each selecting plate is forked at the back and has a recess cut in the
right edge of the left prong, a vertical A³ carried by the box A at its upper end
"

page_text: and by a stud projecting within the box at its lower end restricts the horizontal
movements of the plates, the outer front end of each plate forms, or is provided with a
bracket which is numbered to facilitate its selection by the attendant, a front view of the
upper row of six plates is shown at Figure 3B, the brackets of the two central plates in
each row projects in front of the next adjacent bracket on each side, they in turn
project beyond the two outer ones, this arrangement prevents the possibility of the
attendant pressing back any other than the selected plate, besides enabling the selections
to be made at a much greater speed. The inner back edge of each plate where not cut
away when pressed back by the attendant selects one or more head bolts B2 which slide
in sleys B¹ carried by a sley box B, which is secured to the top of, and moves up, and
down with the upper punch bed of the machine, which lifts the punches C, each selecting
plate where one or more portions of its hack edge is cut away, when pressed back does
not operate the head bolt or bolts at the back of such portion,
Each head bolt forms a hook near its back end, upon which one end of a spring B
is hooked, the front end of the spring being secured to a rod B carried by the sides
of the sley box, when the head bolts are not pushed back by the selecting plates they
are held by their springs in the position shown at Figures 3 and 34, up to a stop plate
B' secured to the lower sley.
The head bolts operate as follows:-
The No. 1 selecting plate when pushed back slides the selected head bolts 3. 4. 5. 6
and 7 back, so as to pass their back ends on to the-top of their respective punches C,
firmly holding them as they descend with the upper punch bed to punch holes in the
card, which when in use allow the tails of the droppers to pass through into the
jacquard cylinder, the head bolt 2 not being pushed back its punch does not punch the
card which then only lifts the No. 1.dropper into operation to traverse the steel or
other bar employed in the machine one gate in the usual way. The head bolt No. 1
next the left side of the sley box B has its back end made somewhat longer than the
others to project over its punch, such punch constantly punching the card except when
a selecting plate punches the No. 1 head bolt back the punch then rises into the recess
cut in the lower edge of the head bolt shown by dotted lines at Figure 3 leaving the
card uncut by that punch. The number on the front end of each selecting plate
shown at Figure 3B indicating the number of gates of the dropper lifted by the uncut
card.
When either head bolt is projected over the top of a punch by the operation of either
of the selecting plates numbered 1 to 40 it pushes back a lever carrying an incline D
shown at Figures 1 and 2 the lever works on an axle secured in an arm projecting from
the left end of the foot plate of the sley box B, the incline raises a rocking truck bearing
lever D¹ the back end of which is connected by a link to the usual releasing and
retaining lever D² while this lever is raised the card carriage D is drawn backward by
the usual weighted cord, the distance of one rack pin, to the next adjacent rack pin in
front of it, when the attendant releases the selecting plate, a spring D³ presses the
incline lever towards the front and the retaining lever is brought down by its spring Do
in the usual way to hold the carriage and the card it carries for the next operation of
the punches.
The rocking lever D₁ is provided with an arm terminating in a knob near the front
of the machine to enable the attendant to release the carriage at will.
Heretofore piano punching machines have been worked by two treadle levers operated
by the attendant one lever working the upper punch bed to cause it to descend, and
the other carrying two connecting links, one link to cause the upper punch bed to rise
and the other link to actuate the traverse of the card carriage.
Instead of which we employ power to drive the machine, this we effect by means of
our second series of apparatus shown at Figures 1 and 2 arranged as follows:-
Beneath the bed of the machine we secure three bearings "shown by dotted lines' at
Figure 2" for a cranked driving shaft E provided with a pulley E', fast tipon it for a
driving belt from a main shaft, and a loose pulley E, the belt being traversed from one
pulley to the other by a forked hand lever E³

page_text: The shaft E carries a fly wheel at its outer end provided with a projection E' on its
circumference nearly opposite to the downward throw of the crank as shown at
Figures 1 and 2, this projection as the shaft revolves strikes a break spring E secured
to the underside of the bed plate to check the momentum of the crank shaft to give
time for a clutch (hereafter referred to) to come into operation, the spring rests upon
an arm E secured to the bed, the arm prevents the spring from touching the fly wheel
except on the surface of the projection.
The crank of the shaft lies under the centre of the width of the card carriage D' and
is connected by a link D to the back end of a lever D' rocking in bearings secured to
the front standard, the front end of the lever is hinged to the lower end of a link De
the upper end of which is hinged to the bottom of the coupling to which the vertical
slide rods are adjusted, the slide rods pass through the lower punch bed and are
secured to the upper bed by which means it is lowered and raised, or instead of
employing a belt pulley fast upon the crank shaft for driving it, we employ our third
series of apparatus, shown respectively in side view and plan at Figures 4 and 5, which
consists of the following parts. Upon the crank shaft E we place a loose pulley F
provided with clutch inclines upon its left side, the pulley is constantly revolved by
the driving belt, but only revolves the shaft when its clutch engages with a clutch
boss F which slides, upon a key carried by the crank shaft E, the sliding of the clutch
boss into gear with the clutch pulley is effected as follows, the clutch boss is grooved
to receive two trucks which revolve on axles carried by the forked end of a right angled
lever which rocks upon an axle pin secured in the underside of the bed of the
machine, the outer end of the lever is attached to a link F3 which has its front end
attached to the lower end of a vertical lever F the axle of which rocks at its left end
in a bearing secured to the top of the lower punch bed and at its right end in a bearing
secured to the top of the bed of the machine, the upper end of the lever is cranked at
a right angle to its depth and stretches across the back ends of the seven head
bolts before mentioned its left end being recessed to receive the extra length of the left
head bolt.
When the clutch boss is in the position shown in plan at Figure 5 the crank shaft is
not revolved but when any head bolt is selected its back end presses back the upper
end of the lever F causing its lower end to move towards the front of the machine
followed by the link F and the outer arm of the lever F sliding the clutch boss into
gear with the clutch pulley and causing the crank shaft to revolve.
The clutch boss is provided with a short incline piece F³ which at every revolution
strikes and slides upon an incline plate F carried by an arm F' which rocks upon
an axle in a bracket FB secured to the bed of the machine, the upper end of the
arin F is hinged to the back end of a hand lever F the under edge of which near its
front end is provided with two notches when the back notch is placed by the attendant
on the lever F in the position shown at Figures 4 and 5 the incline on the clutch
boss F¹ will strike the incline F causing the clutch F¹ to be slid clear of the clutch
pulley F and stop the machine until a fresh selection of the head bolts is made.
when the attendant places the hand lever with its front notch on the lever F the
incline F being away from the clutch. boss it will remain in gear with the clutch pulley
the axle shaft being revolved until the required repetition of similar holes are punched
in the card.
