We WILLIAM HUMPHREYS and ISAAC WYER Portland Road Nottingham Machinists
do hereby declare the nature of this invention to be as follows:-
:-
A metal bed supported by end standards and one or more intermediate standards
is plained true on the top with a V edge at the back and the front, to receive two
saddles, each provided with a pair of bearings above the bed, for the axle of a
double ended bracket, one end of the bracket carries a truck operated by a cam, the
other end supports a bar which carries leads of intercepting combs.
The back of the right hand saddle supports an adjustable bracket carrying a punch
bed and doffer at the back, which receive the bars or sleys to be punched and carry
a punch bolt at the front provided with a stud beneath, which is driven back to
punch the bars or sleys by the bar carrying the leads of intercepting combs, and is
brought to the front again by a spring.
The right hand saddle also carries a pair of studs in each of which is secured a
screw threaded rod, these rods slide through studs carried by the left hand saddle,
the left end of each rod is provided with a nut and lock nut which regulate the
distance between the saddles, each screw threaded rod has an open spring helically
coiled round it, which force the left hand saddle from the right band saddle while
the latter clips the bed.
The front of each saddle carries a pair of bearings in which a cam shaft revolves
the ends of the shaft are carried by the end standards, either end of the shaft is
provided with pulleys for a driving belt. The cam shaft has a key way cut in it its
whole length to receive keys carried by the cams which operate the double ended
brackets before named.
Each cam has a boss on each side which are cut the shape required to actuate
rocking levers to firmly clamp the front Vs of the saddles to the bed, when
not so clamped the Vs are moved from the bed by a spring beneath secured to the
saddle.
When the left hand saddle is firmly clamped to the bed and the right hand saddle
is loosed the latter is moved up to the left saddle by a cord and weight or by a cam
on the left hand saddle.
When in use a comb bar with the combs upon it is taken out of a machine and
placed in proper position at the back of the saddles of the punching machine so that
its intercepting combs will enter the combs on the bar at each revolution of the
cam shaft.
When commencing to punch a bar or sley the saddles are moved to the right end
of the bed and at each revolution of the cam shaft when the intercepting combs on
the left saddle are clear of the combs on the bar at the back of the machine the
saddle is moved to the left by the coiled spring the required distance as determined
by the lock nuts before named, then when the intercepting combs of the left saddle
have again entered the combs on the back comb bar and the intercepting combs of
the right saddle are clear of the combs on the back comb bar the right saddle is
moved up to the left saddle by the cord and weight or cam before named, such
movements being repeated at each revolution of the cam shaft until the whole length
of the bars or sleys are punched.

Figure 4 is a right end view of Figures 3 and 34 showing the bed, cam shaft and
comb bar in section with the right saddle firmly clamped to the bed.
Figure 5 is a side view of the right end saddle with the bearing at the right end
removed to show the position of the cam when the front V is moved from the bed to
allow the saddle to be traversed.
Figure 6 is an underside view showing the top of the bed, with the front V of
the left saddle in the unclamped position.
Figures 7 show front views of pieces of a steel or other metal bar or sley with
holes punched in them.
The corresponding parts in each Figure are indicated by the same letters where
necessary.
Each machine consists of the following parts, a metal bed A of sufficient length to
receive the longest comb bar employed in a twist lace machine, the bed is supported
a convenient height from the floor by end standards A' and one or more intermediate
standards when necessary.
The top of the bed is planed true with a V edge at the back and front, two
brackets A2 A3 are bolted to the top of the bed, each provided with an axle pin on
which a comb bar joint A rocks. The distance the bracket A³ is placed from the
bracket A2 depending upon the length of comb bar A carried by the joints, the
height of the comb bar on the joints is adjusted by a set screw and lock nut AⓇ at
the foot of each joint, through each joint a screw bolt is passed to clamp the bar to
the joint in the usual way "shown at Figures 2 and 4."
Leads of combs A7 are secured on the comb bar in the usual way nearly from
end to end.
Near each end of the bed a bearing A is secured on the top, the bearings carry
a cam shaft B having one end provided with a collar and the other end with pulleys
for a driving belt, by which it is caused to revolve, the shaft has a key way cut in
its whole length to receive keys carried by cams hereafter referred to.
The top of the bed and the V edges receive two saddles B1 B2 "see Figures 3. 34
and 4," each saddle at the front carries a pair of bearings B3 which slide on the
cam shaft, between each pair of bearings a cam B*, provided with a boss B³, on each
side is accurately fitted.
A key B shown by dotted lines at Figure 34 of the same length as the distance
between the bearings is secured to the interior of each cam, and slides in the keyway
of the cam shaft, the revolution of which carries the cams round in the direction
indicated by arrows.

page_text: The bosses B° on each side of the cams B are cut to the shape shown at Figure 5,
each operating a clamping lever B' "see Figures 4. 5. 6" which rocks on an axle B8
the ends of the axle are carried by bearings B secured to the underside of each
saddle in front of the bed A, the centre of each axle is also carried by a thrust
bearing B10 secured to the underside of the saddle between the bearings B.
The outer end of each clamping lever is slotted and provided with an adjustable
stud B7, the inner lower end of each lever presses upon the outer inclined side of a
piece B projecting from the underside of the front clamping V of the saddle.
When the clamping levers are held by the circumference of the cam bosses in the
position shown at Figure 4 the front V of the saddle is forced onto the front edge of
the bed, and firmly holds the saddle in position until the cut. portion of the bosses
allow the stud ends of the levers to rise into the position shown at Figura 5, the
front of the saddle being then held clear of the front edge of the bed, by the ends
of a spring B12 pressing upon the backs of the pieces B₁ on the underside of the
front V of the saddle.
The spring B is carried by a stul passed through a slot in the front ✓ of the
saddle, and screwed into the underside of the saddle, the ends of each front V are
also slotted as shown at Figure 6 so as to slide upon the inner recessed ends of the
bearings B which carry them.
The top of each saddle is provided with a pair of bearings (carrying the axle of
a double ended bracket C provided with a truck C² at the front operated by the
cam B the back of the bracket supports a right angled bar which carries two leads
of intercepting combs C³ "shown at Figures 3, 34, and 4 only a few of the comb
blades are shown in the two leads at Figure 3 and the left lead at Figure 3*.
The whole of the blades are shown in the right lead at Figure 34 engaging with
the inner ends of the blades of one of the combs A' secured to the comb bar A³.
The back of the right hand saddle B' supports an adjustable bracket D, "shown
at Figures 3 and 4," the front end of the bracket is held firm by a U shaped bar D¹
secured to it, the lower ends of the bar being bent round the front ends of the
bearings B³ and front of the saddle, beneath which each end is provided with a set
screw D2 by which the height of the outer end of the bracket is adjusted, and
clamped in position by screws passing through the ends of the bar into the front of
the saddle.
The bracket D carries a punch bed D³ and doffer D which support the bars or
sleys E to be punched.
The upper bar or sley is held down on two studs D and the lower bar or sley is
pressed up to the studs by two pair of levers De hinged to the back edges of the
bracket D the front ends of each pair of levers having a light spring D' hooked
to them.
The front of the bracket D carries a punch bolt D³ provided with a stud D³ beneath,
which is driven backward to punch the bars or sleys, by a bar D10 "shown only at
Figure 4" secured to the right angled bar which carries the leads of intercepting
combs, the punch bolt being brought to the front again by a spring placed between
the bracket D and the stud D the spring riding upon a pin projecting from the back
of the stud. The punch bolt is provided with two steel punches E which may be
packed to any required height by washers, and firmly clamped in position by two
lock nuts E2. Each of the bars or sleys are tightly stretched horizontally while they
are being punched, by the following means: In addition to the oblong sluts near
the ends, by which one end is connected to a spring and the other end to the dropper
box of a jacquard, when the bars are in position in the twist lace machine to which
they belong, a round hole is punched near one end of each bar, which is hooked on
pin E projecting from the right comb bar joint A' the other end of each bar has
piece of gut or cord attached to the oblong slot, the ends of the bars are passed
round grooved pulleys E, carried by an axle pin projecting from a bracket E" "shown
t Figures 1 and 2" secured to the back of the comb bar, each cord after being
passed over a pulley carried by a bracket E6 secured to the back of the bed A, is
provided with a weight E.

page_text: The right hand saddle also carries a pair of studs F "see Figures 3 and 4" in
each of which a rod F¹ is secured, the left end of each rod is screw threaded and
slides through a stud F2 carried by the left saddle, beyond which each rod is provided
with a nut and lock nut F3 see Figure 3 by which the distance between the saddles
is regulated. Each rod has an open spring F helically coiled round it, when the
left hand saddle is unclamped these springs force it from the right hand saddle while
the latter clamps the bed.
Then when the left saddle is firmly clamped to the bed and the right saddle is
unclamped the latter is moved up to the left saddle by a cam FS "shown at
Figures 1. 2. 3 and 4" operating a lever F which rocks in a bearing F projecting
from the left. saddle, the back end of the lever has a rod F8 hinged to its underside
"shown only at Figures 3 and 4" the right end of the rod is screwthreaded and is
passed through a short arm F projecting from the adjustable bracket D and provided
with a nut and lock nut for adjustment.
The top of the lever carries a stud F10 having one end of a cord or gut attached to
it and passed round two pulleys F" carried by the left bracket A2, the cord is then
passed over a pulley G carried by an axle projecting from a wall or beam at a suitable
height above the machine, the end of the cord being secured to an adjoining stud G¹
between the pulley G and the stud the cord is passed under a pulley carried by a
weight F2 which ensures the right saddle being traversed towards the left saddle at
each revolution of the cam shaft.
When bars or sleys are to be punched by the machine a comb bar with the combs
upon it is taken out of the twist lace machine and adjusted upon the comb har
joints A of the punching machine, and a pair of leads of intercepting combs C³ of
the saine guage as the combs on the comb bar, are adjusted and secured in position
on the right angled bar of the bracket C" on each saddle.
The operation of the machine being as follows:-
The bars or sleys to be punched are stretched in the machine and weighted, the
saddles are moved to the right end of the bed, the intercepting combs on the right
saddle engage with the combs on the comb bar, a hole is punched in each bar or sley
at each revolution of the cam shaft, then while the combs on the right saddle are
engaged with the combs on the comb bar, the intercepting combs on the left saddle
move towards the front of the machine, and while they are clear of the combs on the
comb bar the saddle is moved to the left by the coiled springs, the required distance
as determined by the lock nuts before named, and when the intercepting combs of
the left saddle have entered the combs on the comb bar, the intercepting combs on
the right saddle move towards the front of the machine, and while they are clear
of the combs on the comb bar, the right saddle is moved up to the left saddle by
or cord and weight before named, such movements being repeated at
each revolution of the cam shaft until both bars or sleys are punched the length
required.
the cam
The holes in the bars at Figure 7 are shown as having one hole punched in each
to every four gates of the combs on the comb bar. But the saddles may be adjusted
by the lock nuts so as to punch holes in the bars any distance apart according to
the guage.
Having now particularly described and ascertained the nature of our said Inven-
tion and in what manner the same is to be performed we declare that what we
claim is:
The construction and employment of a machine for automatically punching stee
or other metal bars or sleys substantially as described and illustrated in the Drawings
annexed.
