COMPLETE SPECIFICATION.
Improvements in Lasting Machines.
I, JOHN THOMAS AVERY, of No. 304, North Eighth Street in the City of
St. Louis, State of Missouri, United States of America, Gentleman, do hereby
declare the nature of this invention and in what manner the same is to he
performed, to be particularly described and ascertained in and by the following
statement :-
My invention relates to certain new and useful improvements in lasting machines,
such improvements being especially designed for application upon a machine
invented by me, and patented April 12, 1892, under Number 7026 of 1892.
The first feature of this present invention resides in the peculiar construction of
the tack-deliverer and separator, and in the means of operating same.
Second. In the arrangement of the cams and their correlative parts, connected
with the laterally movable head-stock and the gripper-jaws, whereby, when the former
is thrown into an operative position, the gripper-jaws are affected to co-act,
simultaneously therewith, and have imparted thereto a rotary motion.
Third. In the construction and arrangement of means hereinafter to be described,
to rotate the gripper-jaws.
Fourth. In the construction and arrangement of a train of levers connected with
the laterally-movable head-stock and the means for actuating said train, to effect a
forward and backward movement of the gripper-carrier.
Fifth. In the peculiar construction of the tack holder, and the means for thrusting
the same into operative position, and, also, the means for withdrawing the same out
of the way of the "feed" of the stock.
Sixth. In the construction of the folder-arm and its means of operation.
Seventh. In the means for holding the gripper shaft against vertical movement
while the jaws are in the act of gripping; also preventing a too sudden jerk when
the jaws are raised to stretch the upper.
Eighth. In the arrangement and operation of a series of foot levers, in the frame
of the machine, for controlling the movement of the several parts.
And finally, in the construction, arrangement and combination of several minor
features, and as will hereinafter be described, and afterwards pointed out in the
claims.

In the drawings, 1 indicates a laterally-movable head-stock, which has, projecting
from its face, a hub 2, in which is mounted a rock-shaft 4, from the forward end of
which depends a rock-arm 3; to the lower extremity of this rock-arin, is connected
a universal coupling joint 5, to which is, also, connected a link 16, through the
medium of the pins 14 and 15, respectively.
Projecting from the other end of the link 16, is the stud 11, upon which is
loosely mounted a circumferentially grooved wheel 10.
Secured to one of the
guide-ways 255, projecting from the head stock, between which is secured the
gripper-carrier 17, is an adjusting block, 7, provided with slots 7', and 7", through
the former of which, 7', passes the link 16, while, through the latter, is an
adjusting binding nut 115, finding a bearing in the guide-way 255, the function
of which nut being to bind the adjusting rod 7, in a laterally adjusted position
from the head-stock to throw the free end of the link 16, toward or away from
the gripper-shaft 103.
Mounted in the swinging gripper-carrier 17, which is pivotally secured in the
guide way 255, at 214, is a vertically movable gripper-shaft 103, which passes
through a sleeve 12, on its lower end, the function of which sleeve being to
close over the gripper-jaws 107 which are secured to the gripper-shaft, and to
close the same on the upper when the device is being operated. Rigidly secured
to the shaft 103, are collars 207, 210, between which are loosely mounted rings,
or followers, 208, 209, which bear against the end of the lever 104, while secured
to the sleeve, 12, are, also, rigid collars 211, and 8, which also form abutting
shoulders for loose rings, or followers 212, 213, between which is secured the
end of the lever 105, pivoted in the gripper-carrier 17.
205, 206, constitute a toggle joint connection between the levers 104, 105, near
the free ends thereof, said toggle being operated to separate the gripper-jaws
by a link 263 bearing in a head 262, secured to the toggle, the opposite end
of the link having a bearing in a head 261, which head is pivotally connected

page_text: to a depending projection on an angle lever 260, which has a bearing in the
lever 233, which latter is a continuation of the lever 104. Pivoted at 232',
through the medium of the head 231, is a link 230, the lower end of which has
a bearing in a head 229, which head also affords bearing for one end of a
lever 226, which is pivoted at 228, which lever 226 has a fulcrum on a trans-
versely-disposed shaft 235, mounted in the frame of the machine.
The inner end of this lever 226 bears against a cam 111, which cam rocks
the lever and transmits, through the medium of the link 229, angle lever 260,
rod 263 and levers 104 and 105, a separating movement to the toggle-joint
which movement moves the shaft 103 vertically, thereby opening and closing
the gripper-jaws 107.
To obviate the difficulty of the parts not being fitted to act with exact
precision, correlative to each other, I have mounted in a bearing 99, on pivot-
pin 100, a restraining lever, 97-98, the forward end of which, when in its lower
position, rests upon the upper end of the gripper-shaft 103, thereby, not only
tending to hold the grippers to their work, in the act of gripping, but also,
enable the toggle to act more positively at the right moment. The rear end 97,
of this restraining lever is provided with a stud 110 upon which is mounted an
anti-friction wheel 109, said wheel being normally in contact with the periphery
of the cam 111, mounted on the shaft 75 and keyed thereto, through the medium
of the key 76. The diameter of this cam 111 is increased gradually, as at 108,
to enable the anti-friction wheel 109, which rides upon the periphery of the
cam, to gradually elevate the rear end of the lever 97-98, thus forcing the
end 98 down, and with it, the gripper shaft, 103, which not only returns
the toggle-separating mechanism to its normal position, but forces the jaws 107,
out of engagement with the lower end of the sleeve 12, making them ready for
the next operation of gripping.
102 indicates a spring for normally holding the rear end of the lever 97-98 in
contact with the cam 111.
4
Secured to the extreme forward end of the lever 226, at 237 Fig. 2 is a
controlling rod 154 which extends downwardly into the frame of the machine, and
is pivoted to one end of a link 152 at 153.
151 Fig. 25 indicates a stirrup bolted to the underside of the frame and straddling
the link 152, the lower end being closed by a cross-piece 151", which supports a
retraction spring 151", the upper end of which bears against the link 152, and
returns the saine after depression.
150 is a rod passing through the retraction spring and connected to the link 152,
the lower end of the rod passing through a stirrup 149 and terminating in a cap
which confines a compression spring 149", between it and the upper cross-piece of
the stirrup.
141 represents a foot operated lever, pivoted at 142, to a bracket piece 143,
which is secured to a cross-piece 144, of the frame or base of machine 140, by
screws 144. The stirrup 149 is pivoted near the forward end of the foot lever 141,
at 148, whereby, when the former is depressed, it tends to depress the confined
springs 149, in the stirrup 149, through the medium of the cap on the end of the
rod 150, thus exerting a constant downward pressure on the link 152 and its
connected controlling rod 154, which latter controls the movement of the lever 226
and its associate parts which actuate the gripper-jaws.
When the foot lever is released, the retraction spring 151, which exerts a
pressure on link 152, will return the parts to their normal position.
The advantage of making this controlling medium yielding, is derived from the
fact that, very often, the operator will depress the foot lever 141, in advance of
the inner end of the lever 226 coming into contact with a reduced portion of the
cam 111, which will permit the lever 141 to be depressed to its fullest extent and
the lever 226 will always be under tension to automatically throw itself out of
engagement at the proper point.
The means for moving the head stock laterally is substantially the same as that

page_text: shown and described in the Specification to my Patent heretofore mentioned, and
consists of a rock shaft 157 mounted in a pillow block 158, which is fastened to the
bed of the frame 162 by bolts or screws 158¹.
Projecting from the ends of this rock-shaft are two rock-arms 38 and 159, the
former being longitudinally slotted for the passage of an adjustable pivot bolt 164
mounted in the upper end of the controlling rod 116, projecting upward from the
frame, the function of which will be hereinafter described,
Mounted on the frame 112 of the machine, which frame forms a guide-way for
the sliding head-stock, is a rock-arm 165 pivoted on a bolt 166, which has a bearing
in a projection 167 extending laterally from the frame 112. The upper member of
this rock-arm is connected by a bolt 168 to a link 169, the other end of said link
being connected to the head-stock, and through the medium of which the head-stock
receives its motion.
The lower member of this rocking arm 165 is longitudinally slotted for the
passage of the pivot bolt 164.
By slotting the two arms 38 and 165, the pivot bolt 164 is permitted to slide therein,
thus changing the pivotal point of the intersecting axes of the arms, and through
this means the throw of the head-stock is adjusted.
116 indicates a rod, the function of which "being to control the lateral movement
of the head-stock said rod, as before stated, being provided with a pivot bolt 164,
passing through the slots in the arms 38 and 165..
The lower end of the rod projects downwardly through the bed 162 into the
frame of the machine, where it is connected to a link 118 by pivot bolt 117.
The opposite end of the link 118 is connected, by pivot bolt 119, to an angle or
bell crank lever 120 which lever is pivoted at 138 in the rear of the frame 140.
Secured to the lower extension of the bell-crank lever, at 121, is a link or
actuating rod 122, the forward end of which passes through a supporting
bracket 123.
122 indicates a notch. preferably in the lower edge of the rod 122 near its
forward end, said notch being adapted to fall over the bracket 123 and retain the
bell-crank lever in one of its extreme positions.
124 represents a cap piece secured on the end of the rod 122 by binding screw 125,
upon the face of which is secured a knee pad, 126.
Secured to the horizontal portion of the bell-crank lever 120, is a spring 157" to
return the same to its normal position; and at 128, is an extension 127 to the end
of which, at 130, is pivotally secured a stirrup 129 which confines a coil spring, as
in the instance of the stirrups 149 and 151.
132 indicates a rod provided with a cap piece at its lower end against the upper
face of which bears the spring in the stirrup.
The upper end of the rod 132 is secured in a head 133 pivoted to a lever 135
at 134, which lever is fulcrumed in a bracket projecting from the underside of the
bed of the frame.
The forward end of the lever 135 is connected by pivot bolt 136, to a controlling
rod 137, which extends upwardly through the bed 162, and is connected, at its upper
end, in a head 224, forming a universal coupling.
Also connected in this head 224, by pivot bolts 225, is a rock-arm 223, mounted
or a shaft 235, the opposite end, 236, of said arm extending rearwardly and
contacting with a cam face in the side of cam 111.
Projecting upwardly from the coupling 224, is a link 234, the upper end of which
terminates in a coupling head 234, which afford pivotal reception for the end of a
rock-arm 234, secured to the rear end of the rock-shaft 4, which controls the
rotating or crimping mechanism of the gripper-jaws.
This crimping mechanism, as before stated, consists of a depending rock-arm 3,
secured to the forward end of rock-shait 4, the lower end of the arm 3, actuating a
link 16 through coupling 5.
Projecting from the collar 8, rigidly secured to the sleeve 12, are two prongs of a
bifurcated lever arm 9, which pass on each side of the peripherally grooved wheel 10,

page_text: and form a bearing therefor by the impingement of the projecting flanges on the
wheel.
To adjust the throw of the arm 9, and the dependent rotation of the sleeve 12,
which controls the action of the gripper-jaws mounted in the lower end of
shaft 103, laterally adjust the position of the block 7, which forces the free
end of the link 16 towar or from the sleeve, 12, thus increasing or diminishing
the leverage on arm 9, which at its normal position is adapted to receive a given
movement relative to the movement of the link 16.
To increase the degree of rotation of the sleeve 12, it is only necessary to loosen
the nut 115 and extend the block 7 out from the head stock, which will carry with
it the link 16, and shorten the leverage connection therewith with the lever-arm 9,
which short leverage, receiving the same movement of the normal leverage, will
necessarily move the sleeve 12 in a greater degree of rotation.
To diminish the degree of rotation, the block 7 is moved in an opposite direction,
or closer to the head stock, which throws the pivotal point of connection II, away
from the sleeve 12, thereby decreasing the degree of rotation on account of the
longer leverage.
From the foregoing it will be noted, that the bell crank lever 120 mounted in
the frame of the machine, controls, through rods 116, and 137, which are connected
thereto, the length of the stroke of the head-stock and the rotation of the gripper
jaws, which are thrown into and out of engagement by the movement of the knee
pad 126, which, when in its outer position, (as shown in Figure 5) raises the rods,
forcing the pivot bolt carried by rod 116, nearer to pivot 166 causing the upper
end of the slotted lever 165, to which the head-stock is connected by link 169 to
move in a greater are which lengthens the stroke of the head stock. The rod 137,
when the bell crank lever is in this position, is in its lowest position, by reason of
the interposed lever 135 to which it is connected, which causes the cain roller on
lever 223 to run on a smooth surface, which permits the train of levers, of which
this cam roller is the initial source of movement for rotating the gripper jaws, to
remain at rest, as shown in Figure 25. When the knee pad 126 is forced inwardly,
bell crank lever 120, lowers rod 116, thereby shortening the length of the stroke of
the head-stock, and raising rod 137 through medium of lever 135, which causes the
cam roller on lever 223, to be thrown into engagement with cam groove in cam
wheel 11 thus actuating link 234, rocking shaft 4 through rock arm 234 which
rocking movement of the shaft 4 is communicated by rock arm 3, and link 16 to
the slotted fingers 9 on collar 8, which is fixedly attached to sleeve 12.
In Figures 12, 13, 14, 15 and 16, I have illustrated a train of levers and its con-
nections with the gripper-carrier 17, for communicating to the latter a forward
and backward movement which is very desirable when the gripper-jaws are crimping
the upper, when making the short turns around the last, such as the toe and heel.
This train is connected to, and operated by, the rock-arm 159, which is secured.
on a rock-shaft 157 mounted in the pillow-block 158.
The lever 159 is provided at its free end with an anti-friction roller 160, which
engages the cam groove 161 in the cam 113 mounted on the shaft 75, which cam
groove causes the arm 159 to vibrate in a given space, together with its conjoined
arm 38, which latter, as before stated, transmits a variable movement or throw to
the head stock, by the adjustment of the pivotal point of longitudinal intersection
between it and the rocking-arm 165.
19 (see Figures 12, 13, 15 and 16) indicates a plunger block slidingly mounted in
the lower end of the pivoted gripper carrier, said plunger, when in its retracted
position, normally resting against a transverse pin 19, passing through the elongated
open slot 201, therein, said slot extending nearly the whole length of the plunger,
to permit the play of the pin, and having its opened end closed by the link 20,
which is pinned in the plunger by pin 30.
19ª, indicates a compression spring fitted in the plunger opening and in advance
of the plunger, the function of said spring being to receive the thrust of the plunger,
and if, when the gripper takes hold of the upper, the stock is too heavy or stiff to

page_text: yield, the gripper-carrier, with its contained grippers, will not be positively driven
forward, which might, possibly be deleterious to the operativeness of the working
parts of the machines, but will yield and constantly exert a pressure, which when
the folder-arm is thrust out to make the fold, will effectually assist in this latter
operation.
20 indicates a link, one end of which is secured, by pin 30, in the plunger 19 and
its other end, at 28, to arm 21' of an angle lever 21-21', which angle lever is
pivoted, at 26, through hub 22, to a projection in the rear of the frame 112. The
opposite arm 21 of the angle lever is connected to a link 33 by pin 29, the opposite
end of the link being secured to a cross head 34 by pin 31.
This cross head is slidingly mounted on a threaded rod 35, ou one end of which
are the adjusting nuts 41 and 42.
36 indicates a head on the opposite end of the rod 35 between which and the
cross head is a coil spring 34, surrounding the rod 35.
37 indicates a coupling connected to head 36 by pin 32, and by pin 39 to the rock
arm 159.
The arm 159 being vibrated by the cam 113, operates. the train of levers which
communicates a thrust upon the plunger as indicated by arrows in Figure 15, which
thrust as before stated, is directed against the spring 19" and from thence com-
municated to the gripper-carrier 17. The movement of the plunger may be
regulated to any desired stroke by the adjustment of the nuts 41, 42, on rod 35, the
nearer they are placed to the head 36, the quicker the motion will be transmitted
to the plunger and, consequently, a greater throw of the gripper-carrier is obtained,
while a position of the nuts 41, and 42 nearer the end of the rod 35, or away from
the head 36, will accomplish an opposite result.
The function of spring 34', interposed between cross-head 34, and head 36, is to
yieldingly return the gripper-carrier to its seat without shock or jar. It also
permits the parts to assume their normal position with the least friction, and in the
easiest manner.
79 indicates a tack receptacle, preferably of that form and construction illustrated
and described in the Specification of my Patent before referred to said tack
receptacle being mounted on a bracket extension 65 secured to the bracket
frame 78, (which latter forms one bearing for the transverse shafts of the machine),
by screws or bolts 92.
48 indicates the race, provided with a slot or way 49, through which the tacks
are fed to the separator.
Transversely arranged across the lower end of the stationary race-way, is a
reciprocating or sliding tack separator (see Figures 28 and 33), consisting of a
plate 45, which is formed with a recessed portion 55 corresponding in length to the
movement of the plate, the open side of said recessed portion being toward the tack
race, and forming a finger or projection 55'.
Secured to the under side of the plate 45 is a needle or nose 53, of a length
sufficient to substantially close the opening of the recessed portion, the inner
side being curved to form a point, which point is somewhat removed from the
projection finger 55¹ in a direction toward the tack race, so as to throw the point
of the needle in advance of the finger 55' and in the path between the two lower
tacks, the first of which is forced toward and into the recess 55 by the curvature of
the needle.
Secured to the lower end of the tack race, and forming a support for the
reciprocating separator, is a tack-guide, which consists of a depending funnel-shaped
nose piece, 44, provided with a conical shaped opening 57, about its center, one of
the side walls forming the same being in line with the tack race 48 and reduced or
recessed at 58 to permit the point end of the tack to readily enter and fall into the
opening when acted upon by the needle 53.
I prefer to form guide-ways 46 in the upper portion of the tack guide, to clasp
the lips on the longitudinal side edges of the plate 45, the front edge or point of
the needle 53 is preferably inclined or beveled, so as to throw the upper edge in

page_text: advance of the lower, thus stripping the first or lower tack by a shearing motion
and forcing it into the opening 57. To maintain the tack in a vertical position and
overcome the tendency of the needle, in its advance movement, to tilt the tack from
its vertical plane, I form a tack point guide 54 to one side of the recessed portion 58
and in line therewith, upon which guide the point of the tack rides until it is
deposited into the conical shaped opening 57, at which point the tack point guide
terminates, to permit an unobstructed passage or descent of the tack.
I also recess the needle at 56 to accommodate this tack point guide. 51 and
52 are openings for the passage of screws by which the tack guide is secured to the
tack race.
The tack-guide is formed with a laterally extending lug or projection 59, in the
outer end of which is formed an eye 60, for the passage of a pivot pin for pivotally
connecting the link 61 therewith, the opposite end of said link being connected
at 63 to lever 62 which is fulcrumed at 64 to the bracket extension 65 the opposite
end of which laver being connected at 66 in a head 67 in a connecting rod 68
which, in turn, is connected by pin 69 to the member of a rock arm 70 having a
bearing on a transverse shaft 77 mounted in the rear of the frame of the machine.
The other member of this rock-arm is provided with an anti-friction roller 72,
mounted on a pin 71 which roller is adapted to remain in constant contact with the
periphery of a cam 74 by reason of the tension of the spring 671, exerting a
retracting force on the connecting ro 1 68.
At 73 the periphery of the cam 74 is diametrically reduced, into which recess or
reduction, the roller 72 will be impelled by the retraction force of spring 67'
thereby transmitting to the tack separator a reciprocating motion through the train
of levers hereinbefore set forth.
The principle of the operation of the tack-race is as follows:
By reason of the inclined race-way, the tacks will slide down the same by
gravity, and crowd the first or lowest one against the flat edge part of the
projection 55'. When the reduced portion of the cam 74 arrives at a point to
actuate the rocking arm 70, of the train of levers, the separator plate with its
needle is moved, in this instance toward the right, until the needle point will enter
between the first or bottom tack and the next above, which strips said first or
bottom tack from the line and by reason of the curvature of the inner edge of the
needle, will force the same into the opening 57, the tack-point guide in the
meantime acting on the point of the tack to prevent the same from tilting.
Coincident with the stripping operation of the first tack, is the consequent
downward movement of the remaining tacks, which are caught by the outer
straight edge of the needle and held until the needle is withdrawn, at which
time they will fall against the projection 55' and the operation will be repeated
as before.
80 indicates the jaws of the tack holder, the rear ends of which are bent upward
at an incline to accommodate the incline of the sliding arm 81, which arm extends
rearwardly and upwardly at an incline and is pivotally connected by pin 83 to a
connecting rod or actuating link 82 which, in turn, is connected to a rock-arm 85
by pin 84.
The rock-arm is mounted on the shaft 77, at 86', and has a right-angular exten-
sion 87 provided with a pin 88 on its end which supports an anti-friction roller 89
running in the side cam-groove 90 in the cam 74. The peculiar shape of this
groove is adapted to actuate the tack holder correlatively with the reciprocation
of the tack separator, and place the same beneath the opening 57, in the tack-guide
when the needle is thrust forward to strip the tack and precipitate it into the
opening, through which it is guided and falls of its own gravity into the tack
opening in the divided tack holder or jaws, as is fully shown and described in the
Specification to Letters Patent before referred to.
Loosely mounted in a recess 253 in the lower end of the bar 81 and retained
therein by a leaf spring 251, secured in place by screw 250, are anti-friction
rollers 252, the periphery of which extend below the lower plane of the horizontal

page_text: portion of the tack-holder, and rest, when the holder is thrust forward, upon the
prongs of the folder arms 237", as shown in Figure 6. 253 inlicates a shaft
connecting the two anti-friction rollers 252 having bearing in recess 253' and
against which the spring 251 is exerting a constant pressure to hold the same in
place. The folder arm 237 is curved at its outer end, as shown in Figure 6, to 5
enable the same to easily ride over the upper when it is gripped by the jaws 107,
and more readily make the fold. The folder arm is secured to a bracket pro-
jection 238, by screws or rivets 238', extending from an oscillating and reciprocating
rod 239 which is connected at its rear end at 241 to a link or connecting rod 240
whose other end is connected by pin 243 to a rock arm 242 mounted on the 1
shaft 77.
24 represents a right-angular projection extending forward from the rock-
arm 242, on the end of which is an anti-friction roller 245 mounted on a pin 246
said roller running in a cam groove 247 in the side of the cam drum 74.
When the diametrically-increased portion of this cam groove comes in contact
with the anti-friction wheel 245 on the end of the right angular arm 244, it will
depress the same, and extend the rock arm 242 and retract the folder arm.
Simultaneously with this retraction of the folder-arm, the guide-way or oscillating
block 256 will be oscillated by the roller 250, mounted on pin 252 in the
end of arm 249, which arm is connected with the oscillating block 256 by
screws 251, 251, 251", coming in contact with a projection 253 on the periphery
of cam 74 depressing said arm and oscillating the guide-way block in which the
rod 239 is slidingly mounted. This movement of the guide-block will elevate the
folder-arm before its retractive movement is started, carrying it above the fold it
has laid and out of the way of the feed of the upper which is being carried on at
this time.
To return the oscillating block to its normal position, after oscillation, I place a
spring 254 under the rear end of the same as shown.
178 indicates an arm pivoted to the frame of the machine at 178', its forward end
terminating in a head in which is adjustably mounted a retaining finger 179 against
The rear
which a binding screw 180 is adapted to impinge, to hold it in place.
end of this lever is provided with an anti-friction roller 181 mounted on a pin 182,
said roller tending always to contact with a cam 183, mounted on shaft 75, by
the tension of spring 184 secured to lever 178 and rear end of the bracket
extension 65.
The function of this retaining finger is to be forced into the last and hold
the work steady while it undergoes the several operations of folding, tacking,
feeding, etc.
The guide for the last consists of a depending arm 185, secured by screws 188 to
a bracket piece 186, secured to the laterally movable head-stock 1 by screws or
bolts 187 (see Figure 2) said arm being provided with toe and heel projections 185*
and 185 the latter forming a shoulder, against which the last rests and is guided,
and also acts in the capacity of a self-feeder for the last, the reciprocation of the
head-stock giving it a step-by-step movement.
To afford a more substantial rest and means for rigidly holding the last when it
is subjected to the impact of the hammer, which will presently be described, I
provide a reciprocating rest 217 slidingly mounted in a recessed way in the
supporting frame 78, to the rear end of which is connected a link 218 by pin 219,
the opposite end of the link being connected to a rocking arm 220, the opposite
end of the link being connected to a rocking arm 220, by piu 221, which arm is
secured to a sleeve 220ª (see Figure 3), from which projects inwardly a cam
operated rocking arm 220, adapted to be actuated by a cam-groove in the left side
of the cam 113.
The hammer or tack-driver 189 is a vertically disposed rod, secured in a head 190,
projecting laterally from the plunger-shaft 191.
192 and 192' are bearings projecting forwardly from the frame 193, in which the
plunger shaft has a bearing.

page_text: 222 is a collar secured on the plunger shaft by an adjusting screw 2221 confining
a compression spring 216 between it and the bearing 192, the function of this
spring being to exert its force on the plunger-shaft when the same is carried up
and tripped, and impel the shaft and its hammer, or rod, to make the impacting
blow on the head of the tack carried by the tack-jaws.
To elevate and trip the plunger I provide the same with a head 194, which is
cut away, in its inner side, or provided with an opening 194", adapted to receive a
spring-controlled bolt 170, slidingly mounted in the front end of the lever-arm 171,
mounted on a rocking-shaft 173, journaled in the frame 78.
Secured to this rock-shaft, and extending rearwardly, is a rock-arm 172, to the
end of which is connected, by bolt 174, a link or connecting rod 175 whose other
end is connected to a rocking arm 176, said arm being mounted on a shaft 177 on
the frame and adapted to be actuated through the medium of a cam roller 176"
mounted about the middle of said arm, said roller running in a side groove in the
cam 74, as shown in Figure 34. The lever 171 with its contained bolt, upon the
actuation of the several parts herein before set forth, will dip down, and the bolt 170,
being yielding, will be forced back into the lever arm until the spring is permitted
to exert its pressure by reason of the bolt coming opposite the opening 194.
The movement of the lever arm is reversed, and upon its upward movement will
carry, suspended on its bolt 170, against the action of spring 216, the plunger
shaft 191.
To retract the bolt and trip the plunger shaft, I connect to a lateral extension 195ª
of the bolt a link, or rod, 195, whose other end is connected to a lever 196 by a
pin 197, said lever being fulcrumed on a bolt 199, mounted in the frame 78.
198 is a rocking lever, mounted on bolt 199, its lower end terminating in a
cam-roller 200, which bears against cam 111, the face of which is provided with a
trip or lug 200, which coming in contact with roller 200 on lever 198, will force
the same forward, and, it being pivoted upon the bolt, 199, will carry with it its
attached arm 196, which communicates a retracting movement to the bolt, and
trips the plunger shaft.
201 indicates a pillow-block, in which is mounted the shaft 75, carrying the
cams, said block being provided with journal plates 202, and a cap picce 203, for
the bearing.
The shafts 77 and 235 also have one of their ends mounted in the pillow-block,
while the frame or block 78 affords reception for their opposite ends.
204 indicates a driving pulley, through the medium of which power is imparted
to the machine.
