Improvements in Card Setting Machines.
I, NATHAN CHACE ESTES, residing in the Town of Leicester, in the County
of Worcester, in the State of Massachusetts, one of the United States of America,
Manufacturer, do hereby declare the nature of my invention for Improvements
in Card Setting Machines, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement :-
My invention relates to card setting machines used in the manufacture of card
clothing, and the object of my invention is to improve upon the construction of
card setting machines, as now ordinarily made, and more particularly to improve
upon the construction and manner of operating the carriage for carrying the fillet,
in which are inserted the wires, and also the mechanism for drawing the wire into
the machine.
My invention consists in certain novel features of construction and operation of
the carriage for carrying the fillet, and of the mechanism for communicating to
said carriage a lateral endwise intermittent motion, and also of the mechanism for
drawing the wire into the machine, as will be hereinafter fully described, and the
nature thereof indicated by the claims.
I have only shown in the drawings my improvements in card setting machines,
the other parts of the machine, which may all be of the ordinary and well known
construction and form no part of my invention, are left off for the sake of clearness,
and in order to simplify the description.
Referring to the drawings:-

thereto, looking in the direction of arrow a, Fig. 2.
Fig. 2 is a plan view of the parts shown in Fig. 1.
Fig. 3 is a cross section, on line 3, 3, Fig. 2, looking in the direction of arrow b,
same figure.
Fig. 4 is, on an enlarged scale, a detail, partly in section, of the wire gripping
and drawing in mechanism.
Fig. 5 is, on an enlarged scale, a rear view of the laterally moving carriage,
taken at line 5, 5, Fig. 2, looking in the direction of arrow e, same figure.
Fig. 6 is a vertical cross section, on line 6, 6, Fig. 5, looking in the direction of
arrow d, same figure, and,
Fig. 7 is, on an enlarged scale, a side or edge view of the lever which draws in
the wire, looking in the direction of arrow e, Fig. 2.
In the accompanying drawings, 1 is the bed of the machine, on which are
supported the several parts of my improvements. 2 is the driving shaft, mounted
in bearings 3 on the upper ends of stands 4 on the rear of the bed. The shaft 2 bas
a driving pulley 5 on one end thereof, and a balance wheel 6. On the front part
of the bed 1, mounted in bearings 7 on stands 8, are the arbors 9' and 9" of the
laterally moving carriage 9, which carries the fillet in which are inserted the
wires.
The carriage 9 has the two upwardly extending posts 10, in the upper ends of
which are mounted adjustable rods 11, between which the fillet extends in the
ordinary way, and also the rod 12 which extends back of the fillet. The carriage 9
bas in this instance the upwardly projecting part 13 extending between the posts 10,
to the back of which is adjustably secured the rest 14, by screws 15 extending
through vertical slots 14' in said rest 14, see Fig. 5. The rest 14 consists of a

page_text: piece of sheet steel with a hardened edge, over which the wire is bent, after it is
thrust through the fillet.
Extending down from the carriage 9 are two legs 16, the lower ends of which
extend into the slide or way 17, secured to the bed 1 by screws 18, and adjustable
back and forth on the bed, to vary the inclination of the back rest 14, to obtain
any desired angle for the wire to enter through the leather.
Connected with one arbor of the carriage 9, in this instauce the longer arbor 9¹,
is a clamp device, for connecting the arbor to the cam wheel, which communicates
endwise or lateral motion to said carriage.
The clamp connection between the carriage, carrying the fillet, and its operating
cam wheel, which prevents any endwise motion of said carriage, except that which
is. communicated to it by the operating cam wheel, and holds said carriage
rigidly while the wire is being inserted in the fillet, is an important feature of my
improvements.
The clamp connection between the arbor of the movable carriage and its
operating cam wheel, consists in this instance of a plate or piece of hardened
steel 20, forming the stationary lip or jaw of the clamp, and which in this instance
is secured to the downward projection 19 on the arbor 91, by a plate 21 and
screws 22, as shown in Fig. 5, and a second plate 23 forming the movable lip or
jaw of the clamp, which in this instance is mounted and slides laterally in an
arm 19 extending downwardly from the arbor 9', being retained in place by a
plate 24 secured by screws 25 to the arm 19', and provided with a horizontal
slot 26 into which a pin 27 on the movable plate 23 extends.
The rim of the cam wheel which communicates motion to the carriage 9, extends
between the jaws 20 and 23 of the clamp device on the arbor 91, and the movable
jaw 23 is held in engagement with the cam rim by a lever 28, pivoted on a screw 29
on the plate 24, and pressed against the pin 26 on said jaw 23 by a spring 3, secured
to the upper end of the lever 28 and to the post 10, see Fig. 5.
To communicate a lateral or end wise motion to the carriage 9, I employ in this
instance a combined cam wheel and ratchet wheel 31, of the shape and construction
shown in the drawings. The cam wheel 31 is fast on a shaft 32 located below the
hed 1, and consists in this instance of an outer rim 31' divided into six cam
sections, each one of which will move the carriage 9 the full distance it travels in
one direction. The cam rim 31' is connected by spokes 31" with the hub 31", as
shown in Fig. 3.
The rim 31' of the cam 31 is provided on each side with inclined surfaces as
shown, on which the ends of the lips 20 and 23 of the clamp travel, to communicate
end wise motion to the carriage 9, and after each movement of the carriage, the
lips rest upon the steps 32', see Figs. 3 and 5, at the end of the inclined surface,
which steps are in a plane at right angles to the plane of movement of the carriage,
so that the carriage will be held perfectly motionless while the wire is being inserted
in the fillet. The cam wheel 31 is operated in this instance by a pawl 33, which
engages ratchet teeth 33' on the periphery of said cam 31, to communicate a regular
intermittent motion to said cam, and through said cam a regular intermittent
end wise motion to the carriage 9, first in one direction, and then in the other; the
length of travel of the carriage is regulated by the length of the cam sections,
shown in Fig. 2, on the cam, according to the width of the fillet in which the wires
are set.
By providing the periphery of the cam 31 with ratchet teeth, I operate said cam
by the actuating pawl 33 without any intermediate mechanism. Said pawl 33 is
pivoted on a swinging arm 34, pivotally hung at its lower end on a screw 35 secured
in a stand 36, extending up from the bed 1. A spring 37, secured at one end to
the upper end of the swinging arm 34, bears at its free end on the pawl 33 to hold
the same in engagement with the teeth 331 on the cam 31. Motion is communicated
to the swinging arm 34 by a cam 38 fast on the driving shaft 2. A spring 39
secured at one end to the swinging arm 34, and at its other end to the pin 40, acts
-to keep the swinging arm 34 in engagement with its operating cam 38.

page_text: The cam wheel 31 is preferably of the shape shown in the drawings, and the
ratchet teeth 33 on the periphery thereof follow the shape of the cam, so that
each successive tooth will occupy a different position relatively to a plane at
right angles to the axis of said cam, that is said teeth will extend in a zig zag
line.
It will thus be seen, that very direct motion is communicated to the cam 31, and
through said cam to the carriage 9 carrying the fillet, so that said carriage will
have a very accurate motion, and the clamp connection between the cam and the
carriage, will hold the carriage very accurately, and prevent any endwise motion
when the cam stops and the wire is inserted in the fillet.
And further in my construction of the carriage carrying the fillet, and the
mechanism for operating the same, I raise the bearing or point of contact between
the carriage and its operating cam, and thus bring the top of the back rest over
which the wire is bent nearer and almost in a line with said bearing, and thus over-
come any vibration or movement of the rest independent of its movement with the
carriage, so that the teeth are set much more accurately than in the old style
machine, in which the distance between the top of the rest and the bearing or
point of enntact of the operating cam of the carriage is much greater.
I prefer to arrange the ratchet teeth on the periphery of the cam rim 31' as
shown in the drawings and above described, but it preferred the ratchet teeth may
be located on the periphery of the bub 31", or on the end thereof, as indicated by
dotted lines in Fig. 3, and driven by a pawl properly arranged, and driven from
the shaft 2.
It will be understood that the fillet into which the wires are to be inserted has to
he fed upwardly at regular intervals, and in order to bring the several parts of my
mechaniems into more compact form, and to occupy less space, I preferably core
or cut out the carriage 9 between the posts 10 and the legs 16, just below the
rests 14, as shown in Fig. 6, and arrange in said cut out portion the toothed feed
roll 41, which is fast on a shaft 42, which in this instance extends loosely within
one end of the arbor of the travelling carriage 9, and is adapted to have a regular
intermittent rotary motion, by means of a ratchet wheel 43 splined to one end of
the shaft 42 of the feed roll 41, see Fig. 2, so that said shaft 42 may have a lateral
or endwise motion with the carriage 9. The ratchet 43 is operated by a pawl, not
shown. In connection with the feed roll 41, I provide a friction roll 44, mounted
to turn in the upper ends of arms 45, pivotally attached by screws 46 to the inner
edges of the legs 16 of the carriage 9, as shown in Figs. 3 and 6. The lower
ends of the arms 45 are adjustably secured by screws 47 to the legs 16, to
vary the pressure of the roll 44 on the fillet passing between said roll 44 and the
roll 41.
I may provide a longitudinal slot 49 in a rearwardly extending lip 50 on the
carriage 9, ue shown in Fig. 6, through which slot the fillet passes up and extends
between the rolls 1 and 44. The width of said slot 49 may he regulated by the
plates 51, adjustably secured to the lower part of the carriage by screws 52, see
Figs. 5 and 6.
I will now describe my improved construction of the lever, which operates to
draw the wire into the machine, preparatory to its being bent and cut, and inserted
into the fillet.
In my improved construction of said lever, 1 provide in the end of said lever a
device for gripping the wire to draw the wire into the machine when the lever 53 is
moved in one direction, and to release the wire when the lever is moved in the
opposite direction, preparatory to again gripping and drawing in the wire, instead
of employing a separate slide, carrying the gripping device, which slide is operated
by said lever, as is customary.
Referring to Figs. 2 and 7, the lever 53 referred to is made of angular shape,
and is pivoted on a pin 54. The rear arm 53¹ of the lever 53 is adapted to be
engaged at its end by a cam 55 on the driving shaft 2, which cam com-
municates a positive motion to said lever in one direction to draw in the wire, and

page_text: a spring 56' attached at one end to the arm 53' of the lever, and at its other end to
the stationary part of the machine, in this instance to the bed, acts to move the
lever 53 in the opposite direction. The arm 53" of the lever 53 is made as shown
in Figs. 4 and 7. The outer end of the arm 5311 is provided with a downwardly
projecting portion in which is arranged the mechanism for gripping the wire, which
passes through a hole 56¹ in said downward projecting portion, and is gripped
between a stationary pin 57, secured in the end of said arm, and a longitudinal
moving spring actuated pin 58, supported in the downwardly projecting portion at
the end of said arm.
When the arm 53 is moved back by the spring 56, into the position shown in
Figs. 2 and 4, it will engage a set screw 59, to limit said motion. As the cam 55
revolves and engages the opposite end of the lever 53 to move it on its pivot
point 54 to draw in the wire, the outer end of the spring actuated pin 58 will
engage with a lever 60 pivoted at 61, and which is actuated by a spring 62 to
move in the free end of the lever 60, which is pivoted on a link 63, connected to
one end of a sliding arm 64, provided with a strap 65 at its other end, into which
extends a cam 66 on the driving shaft 2, to communicate a regular reciprocating
motion to said slide 64. The other end of the link 63 carries a head 631 thereon,
adapted to engage the head of a spring actuated pin 67, which has a longitudinal
motion in a stationary part 68, and acts, in connection with a stationary pin 69 in
the outer end of said part 68, to grip and hold the wire, passing through a
hole 70 in said part, upon the return movement of the lever 53, in the ordinary
way.
It will thus be seen, that as the lever 53 moves in the direction of the arrow,
Fig. 4, to draw in the wire, the lever 60 engaging the head of the pin 58, and
actuated by the spring 62, will force inwardly said pin 58 to grip the wire, and at
the same time the sliding rod 64 moving inwardly, will move the link 63, and
release the pressure of the end 631 thereof on the pin 67, to allow the wire to pass
freely through the hole 70 in the arm 68. After the lever 53 has reached the end
of its travel, the sliding rod 64 moves in the opposite direction, and draws back the
lever 60 to release the pressure thereof on the pin 58, and allow said pin to release
the wire, preparatory to the lever 53 returning to its first position; at the same
time pressure is communicated to the pin 67 by the end 63' of the link 63, to grip
and hold the wire upon the return movement of the lever 53.
By arranging the wire gripping device in the end of the lever 53, I simplify the
number of parts, and do away with the transverse slide ordinarily employed to grip
the wire.
The advantages of my improvements in card setting machines will be readily
appreciated by those skilled in the art. They simplify the construction of the
machine and reduce the cost thereof, and the working parts are more on the outside
of the machine so that they are easily accessible to the operator, thereby saving
much time and enabling one operator to care for a greater number of machines. And
further the point of contact of the operating cam is just below the plane of travel
of the spindles or arbors of the carriage, while the top of the back rest is just above
the plane of travel of said spindles or arbors, and therefore the teeth must be
inserted with great accuracy, which is very important.
It will be understood that the details of construction of the several parts of my
improvements may be varied if desired. The shaft of the feed roll may be located
under the carriage arbors if preferred. The operating cam wheel 31 may have
a continuous rotary motion if preferred, instead of an intermittent motion as above
described, a continuous rotary motion being communicated to said wheel from the
driving shaft 2 through a system of gears in any well known way.
