COMPLETE SPECIFICATION.
Improvements in Machines for Driving Nails, Pegs, and the like into
Heels and other Articles.
I, ERASTUS WOODWARD, a citizen of the United States of America, residing at
32 Wigglesworth Street, in the Town of Somerville, County of Middlesex and
State of Massachusetts, one of the United States of America, Mechanical Engineer
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 :-
My invention relates to improvements in machines by which nails pegs and the
like are partly driven into a pile of heel lifts in order to form a heel blank ready
to be attached by the same nails to the shoe, or into other articles.
..
One object of my invention is to produce a machine in which the undriven or
feeding nail will control the feeding operation of the heel supporting plate, so that
if a nail is not received from the nail race-way into the nail feed-way and thence
fed forward toward the position to be driven by the nail driver, the heel plate will
not be moved and the heel will thus remain stationary until a nail is so received
and fed into position to be driven by the driving mechanism into said heel. This
and other objects are carried out in the manner hereinafter fully and at large set
forth.
My invention consists of mechanism by which the heel will be fed after each
operation of the nail driver, but will not be so fed unless a nail has been received
from the nail race-way into the nail feed-way and fed forward into position to be
driven into the heel by the nail driver, the feeding or undriven nail thus acting to
control the feeding of the heel plate and the heel carried thereon.
My invention further consists in certain novel features hereinafter described and
particularly pointed out in the claims.

Like letters of reference refer to like parts throughout the several views.
Referring now to the drawings (see Figures 1 to 5), A represents a table suitably
supported from the floor. B is a plunger head carrying the plunger C, which is
mounted therein and carries the nail driver D, and receives its motion from a crank
arm E, mounted on a suitable driving shaft Ei, which receives its motion from any
suitable power, and by means of the ordinary clutch operating devices can be
connected with or disconnected from the driving power. In the table A there are
ways F, in which moves a slide F' carrying a heel plate F capable of rotation on
an axis F3. On the under side of this plate there is a series of feed pins F adapted
to engage with the feeding mechanism hereinafter described.
A heel holding device consisting of a series of pins F is located above the
plate F and holds the heels F8 in position to receive the nails.
The slide F, carrying the heel plate, can be drawn toward and held in contact
with the feeding mechanism by means of a weight attached to one end of a cord
running over a pulley, the other end of this cord being attached to an eye projecting
from the bottom of the slide or by means of a spring suitably connected to said
slide and table, or in any other desirable manner.
On the end of the crank arm E there is journaled a pitman E connected at its
Jower end to a curved arm E3 pinned on a shaft E, which has a right angle
extension E, having a pin moving in a vertical lever E fulcrumed above on a
suitable fixed shaft E7, so that the said lever has a to and fro motion from the
power transmitted from the block Es. The lower end of said lever E is connected
by a pin E to a block E' mounted in an upright projection E10 forming a part
of the slide H, which is moved to and fro in the guide-way H' by the oscillations
of the vertical lever Ee fulcrumed on the shaft E. On said slide H there is
pivotally connected a pawl G, pivoted at G¹ to the slide H, and to its rear end there
is connected one end of a spring G3, whose other end is connected to the pro-
jection E at G³, the tendency of which spring is to draw said rear end toward
the upright projection E and to cause the forward end to move toward the ratchet
wheel J, to which is secured the sprocket wheel J, both of which are mounted
loosely on the shaft J, having a circular head J3 set in the upper side of the
sprocket wheel J. On the forward end of the pawl G there is a finger G₁ secured
by suitable screw G' to said forward end, and the limit of movement of said forward
end, due to the tension of the spring G, is limited by a pin G on slide H. From
the forward end of the pawl G and on one side of the finger G there extends
upwardly a pin G7 having its upper end G8 cut substantially in triangular shape.
The rotation or feeding of the heel plate F is caused by the engagement of the
teeth of the sprocket wheel J' with the feeding points or pins F on the heel plate,
and the operation of said ratchet wheel J and sprocket wheel J is caused by the
pawl G, so that it will be understood that the feeding of the heel plate depends
upon the movement given to the ratchet wheel J₁ by the pawl G, and it will be
hereinafter explained how the said pawl G is caused to engage said ratchet wheel J

page_text: when a nail passes from the nail race-way into the nail feed-way and is moved
forward into position to be driven by the nail driving mechanism into the heel, and
it will be set forth how said pawl is prevented from operating the said ratchet
wheel J when a nail has not been received from the race-way into the nail feed-way
and moved forward toward the nail driving mechanism.
When the feeding operation is finished so that the last one of the feeding points
or pins, which I have marked F", comes between the teeth of the sprocket wheel J,
a corner F of the heel plate will come in contact with the knob K on the end of
the arm K', extending from the hub K pivoted on a pin K³. Another arm K*
extends from the hub K to the clutch operating mechanism K, and the movement
imparted to said knob K will release the arm K from said clutch operating
mechanism K and the machine will automatically stop.
The hub K' is provided with a handle K, so that the lever may be operated
by hand to stop the machine. A suitable spring K' is secured to the arm K* and
to the frame of the machine, and tends to hold said mechanism in the position shown
in Figures 1 and 5, so that the tripping of the clutch operating mechanism will
take place when the corner F' contacts with the knob K and moves it rearwardly
from the position shown in Figures 1 and 5.
The nail driver D is secured to the bottom of the plunger C by suitable set
screw D', and on the adjacent side of said plunger there is located a jaw separator M,
adapted to move up and down in a slot M' formed in one side of the plunger C,
(see Figures 2 and 3) and it is provided with a slot M. The said jaw separator
extends downwardly and is provided at its lower end with a wedge-shaped point M²
for a purpose hereinafter described. On one side of the jaw separator M there
is arranged a link L, having a slot L, and through the upper end of said link there
is a pin L', which extends through the link into the slot M of the jaw separator M,
and is secured in the plunger C, and is adapted to have a movement up and down
in said slot, and in the upper position of the plunger, as shown in Figure 1, said
pin L' holds the jaw separator M in its upper position, and when movement is
communicated to the said link L to cause it to move downward, the pin L' when it
reaches the position shown in Figure 2, moves said jaw separator downward from
the position shown in Figures 1, 2 and 3.
In the bottom of the slot L' there is located a pin N, to which is pinned by a
set screw an arm N' extending to and surrounding the shaft O and provided with
a right angle extension No partly around the shaft O, and adapted to move in a
recess No cut in the fixed sleeve N2. A spring N3 has one end secured to said
sleeve N2 and the other end to a pin N on the upper end of the arm N'. By
means of this extension No working in the recess No, the movements of the link L
and plunger C are communicated to the fixed sleeve N' and shaft O. By means
of this recess N the upward movement of the arm N' with the link Land plunger C
is provided for in the event of the shaft O and sleeve N heing stopped by the
fouling of the nails or other obstruction, as the extension N moves in a recess N,
toward the upper front edge of said recess N° but not in contact therewith, and in
said upper movement of the plunger C the spring N³ is put under tension so that
after removal of the nail which caused the stopping of the nail feeder R, and
shaft O, the spring N³ moves said sleeve N2 to its upper normal position, and the
extension No bears against the rear upper side of the recess N³, and in such position
in the downward movement of the parts communicates motion to the sleeve N2 and
from said sleeve to the shaft O, on which the sleeve N is pinned fast, and in the
upward movement of the plunger C and co-operating parts motion is communicated
to the fixed sleeve N and shaft O, through the spring Na, the upper end of which
moving upwardly with the plunger C pulls the sleeve N2 and shaft O, and causes
the revolution of the same in a direction opposite to that caused by the downward
movement of the plunger C and co-operating parts.
In the downward movement of the plunger C, the link L moves downwardly, as
indicated in dotted lines Figure 2, and the jaw separator M does not receive any
downward movement until the pin I reaches the bottom of the slot M³ in the

page_text: upper part of said jaw separator, and then in the continued downward movement of
the plunger C the link L, jaw separator M and nail driver move together by the
continued descent of the plunger C, but from the above it will be seen that the
nail driver D moves downwardly a distance equal to the length of the slot M' in
the jaw separator M before the jaw separator receives any downward movement.
When the upper part of the slot L' in the downward movement of the plunger
comes in contact with the pin N, the shaft O is caused to rotate by the lever N' in
the downward movement of the plunger, and said shaft is rotated in an opposite
direction when the ascent of the plunger takes place.
On the same shaft O and to the left of the lever N¹ at P¹ there is a vertical
arm P, pinned fast on the said shaft, and at its lower end is provided with a right
angle pin P, surrounded by an anti-friction roller P, fitting in a recess R of the
nail feeder R, so that the opposite oscillations of the shaft O, which take place
in the upward and downward movement of the nail driving mechanism are
imparted through the arm P to the said nail feeder R, and move the samne
forwardly and rearwardly between the plates RR'.
The link L, lever N¹, sleeve N' and arm Pare practically one, and move
together, and in the upward movement of the machine when the nail feeder R
comes in contact with too solid a resistance, as for instance, a nail becomes fouled,
the lever N and sleeve N will separate and the sleeve N' will stop with the
shaft O, and the lever N', turuing on said shaft will continue upwardly with the
link L, and thus the stopping of the rotation of the shaft O, by the nail feeder R
through the arm P encountering an obstruction, does not interfere with the upward
movement of the plunger C and its co-operating parts, aud this arrangement acts
as a safety valve to protect the working parts of the machine when a nail has
become fouled in the nail feed throat, and upon the removal of the obstruction the
shaft O, arm P and sleeve N 2 return to their proper relative positions by means
of the tension of the spring N°.
In the operation of the machine a line of nails Q (see Figures 10 and 11) are
arranged in a nail race-way Q leading into the opening R cut in the plate R of
the nail feeding mechanism, so that there is always a nail ready to pass into said
opening R and from there into the nail feed-way, in a manner hereinafter described.
The said nail feeding mechanism consists of two side plates R and R', between
which there is formed a nail feed way R, in which is adapted to reciprocate the
nail feeder R in its to and fro movements caused by the pin P2 on the end of the
arm P, mounted fast on the shaft O and fitting in a recess R of the said nail feeder,
(see Figures 1 and 18).
On the forward end of said nail feeding mechanism there is a block R secured
by screws to the side R, and having an opening R' in which the nail driver D is
adapted to reciprocate, and, below said opening R' there is formed between the
plates R and R the circular passage R", (see Figures 13, 18 and 20), in which the
nails are fed by the nail feeder R to receive the impact of the nail driver D in its
downward movement. In one side of said block Re there is a recess R', in which
the forward end of the nail feeder R moves in feeding the nails into the
passage R, (sce Figures 10, 11, 12, 14 and 20). In the upper position of the
parts shown in Figure 1, the pin P with the anti-friction roller P3 fitting in
the recess R of the nail feeder R moves said feeder forward from the position
shown in Figure 11 to the position shown in Figures 10 and 12, so as to feed a
nail received into the nail feed-way R³ forwardly into the nail passage R to receive
the impact of the nail driver 1 and be driven into the heel, and the machine is so
timed that in the upward movement of the nail driving mechanism the arm P,
with its pin P' moves the nail feeler R forwardly to feed another nail into the
passage R to receive the next impact of the nail driver as it descends, and in the
descent of said nail driving mechanism the pin P2 in the recess R³ moves said
nail feeder R rearwardly past the opening R' into which the nails are received
from the nail race-way Q in order to permit another nail to pass from said
opening R into the nail feed-way R, in a manner hereinafter explained, so that

page_text: in the upward movement of the nail driving mechanism the shaft O rotates and
through the arm P moves the nail feedler R forwardly, and in the downward
movement of the nail driving mechanism the shaft O rotates in an opposite
direction and through the arm P moves the nail feeder R' rearwardly.
At the rear end of the plate R' there is cut a slot R10 open at its rear end, see
Figure 14, and there is adapted to move in said slot a pin R" secured to and
extending out from the nail feeder R, the said pin in the position shown in
Figure 14 controls the distance the feeder R moves forwardly, and its rearward
movement is controlled by the spring R12. At one side of said nail feeder R
there is arranged a movable plate S, see Figures 10, 11, 14, 18 and 24, and referred
to in this specification as the nail separator, the function of which is to permit but
one nail at a time to pass from the vertical opening R' into the nail feed-way R,
so that but one nail at a time can pass into the passage R8 and receive the impact
of the nail driver, and thereby prevent clogging and injury to the machine.
This nail separator at its forward end and on the opposite side from the
opening R is cut away aud inclined inward from the top to the bottom, as shown
at S', Figures 19 and 20. From the lower end of said separator there extends
outwardly a pin S, Figure 18, adapted to move in a slot S of the side R. Said
pin is secured at its outer end to a suitable vertical arm S5 mounted on a pin S
located in a slot S' formed in said vertical arm S, and the plate S is arranged on
the outside of said arm, and through it the pin S passes to hold said arm in place.
To the upper end S of said arm (see Figures 12, 18, 21 and 24) there is rigidly
secured a horizontal pin S, and near the outer end of said pin there is an anti-
friction roller S, which is adapted always to be in contact with an upward
extension R" of the nail feeder R, on one side of the recess R (see Figures 12,
14, 18 and 21), so that the forward movement of the nail feeder R* caused by the
arm P in the upward movement of the nail driving mechanism imparts movement
to the vertical arm S and moves it into the position shown in Figures 12, 14
and 18, so that the upper end moves forwardly, and the lower end moves rear-
wardly, and with it the pin S3 and the nail separator S, so that the rear end of the
separator S projects beyond the plates R R. In the downward movement of the
uail driving mechanism the arm P through its pin P' imparts a rearward movement
to the nail feeder R, and as the upper projection R" recedes from the anti-friction
roller S on the pin S, the spring R secured to the nail feeder R' by a pin R",
and to the extreme end of the pin S10, exerts its tension and pulls the upper end
of the vertical arm S rearwardly, which being mounted on the pin S, throws the
pin S at the lower end forwardly in the slot S, and thereby imparts a forward-
movement to the nail separator S, and in said forward movement as it passes the
vertical opening R, the upper part of the pointed end S passes in between two
nails in the line of nails in the opening R2, and moves one nail into the nail feed-
way R (see Figure 11), the inclined side of said separator acting to push one nail
into the nail feed-way, so that there is always one nail in said feed-way ready to
be fed forward by the nail feeder Ras it moves forwardly in the upward movement
of the nail driving mechanism. The pointed end of the uail separator S in
passing between two nails moves but one into the feed-way and cuts off the nails
back of the nail forced into the nail feed-way, so that but one nail at a time can
be received into the said nail feed-way. The machine is so timed that the forward
end of the nail feeder R is within the block R when the nail separator has
passed back of the first nail on the line of nails in the opening R, see Figure 10,
and by such an arrangement more than one nail is prevented from passing into the
nail feed-way R in front of the nail feeder R, as said separator closes the
opening R' until the nail feeder has passed in advance and closes said opening R²,
so that another nail cannot pass into said nail feed-way R. Thus it will be seen in
the upward and downward movement of the nail driving mechanism the pin P
imparts respectively a forward and rearward motion to the nail feeder R, and the
rearward and forward movements of said nail feeder actuate the nail separator S
in its forward and rearward movements, but the forward movement of the nail

page_text: feeder R causes the rearward movement of the nail separator S, and the rearward
movement of said nail feeder causes the forward movement of said nail separator,
as previously described.
It is obvious that in no case can the nails in the opening R2 pass into the nail
feed-way K, as the forward wedge-shaped end S' in its forward movement passes
between two nails as the nail feeder R begins its rearward movement, and when
said mail feeder has passed rearwardly of the opening R' one nail is fed in the
nail feed way by the forward end of the nail separator, see Figure 11, so that in
no case can more than one nail have uninterrupted movement into the nail feed-
way R, because when the separator is in its rearward position the nail feeder is in
its forward position and closes access to said feed-way R³, and when the nail
feeder R begins to recede, the separator moves forward, and when the nail feeder
has passed rearward of the opening R2 the nail separator has passed in between
two nails and fed one into said feed way, anel blocked the other nails from passing
therein. On the inner side of the plate R, see Figure 20, there is provided an
inclined wedge-shaped recess R into which the inclined wedge-shaped end S' of
the separator S is adapted to fit in its forward limit of movement.
At the forward end of the plate R' there are pivoted at u' the nail holding
jaws u, inclined inwardly near their lower ends, as shown at u, and normally held
together by the spring u, secured to the pins w. On the side plate R', and
against the upper sides of said jaws there is arranged a plate T, in order to assist
in holding the jaws in their proper positions. The said jaws are substantially of
the same construction, and have two off-sets us and u at their lower ends which fit
respectively under the lower end of the plate R', and the off-set R18 of the plate R,
see Figure 13, and at the lower end of said jaws there is formed in each jaw a
recess u', which match and together form a circular passage &, when the jaws are
held closed by the spring w, and said circular passage is about the same diameter
as the body of the nail, and in the lower end of oue of the jaws, as shown in
Figure 14, a movable pin u is located, its forward end extending outwardly in
the recess u about half way across the passage us, and against its rear end a
spring, secured to the upper part of said jaw, bears and tends to hold said
pin out into the passage us. When a nail is fed forward into the passage R8
it falls vertically in the passage us, formned by the recesses in the two jaws, and
is held in this position by the pin u which slightly yields to the fall of the nail Q
which is held in a position, (shown in Figure 16) ready to receive the blow of the
nail driver and be driven into the heel. The two jaws thus acting to hold the nail
vertically, so that it will be driven straight into the heel.
As shown in the drawings in dotted lines, Figure 14, and in full lines Figure 1,
the jaw separator M, with its wedge-shaped point M2, reciprocates between the
jawa u, and, as previously stated, the machine is so timed that the pin L' does not
reach the lower end of the slot M' in the upper end of the jaw separator until the
nail driver D has acted on the upper end of the nail and driven it partly into the
heel, and then the jaw separator moves downwardly with the continued downward
movement of the nail driver and separates said jaws, in order that in the revolution
of the heel the nail may pass from between the recesses u7 at the lower end of the
jaws, and thus permit the movement of the heel, and the part of the heel to receive
the next nail comes under the said passage us, as at the beginning of the upward
movement of the nail driving mechanism the feeding mechanism acts on the pins F
to revolve the heel plate for the heel to receive the next nail, so that as the jaws
are separated at the downward limit of movement of the nail driving mechanism,
the nail driven into said heel leaves said passage us at the beginning of the upward
movement of the nail driver D, and before the jaws close by the upward movement
of said jaw separator M, and from the above it will be seen that the nail is held by
said jaws and is driven a sufficient distance in the heel to guide it during the rest
of the driving operation before the jaw separator acts on said jaws to move them
from the nail, and by this provision the nail is driven straight into the heel the
entire distance before the jaws are opened the full distance to release said nail from
the recesses u'.

page_text: Pivoted to the upper aide of the plate R' at V₁ there is a device V which will
be called a nail feeler, baving its forward end V partly across the forward end
of the nail feed-way R³ (see Figure 12) owing to the tension of the spring V 5
secured at one end to a pin to the under side of said nail feeler, and at the other
end to a pin on which one of the jaws is pivoted, and tends to hold said feeler
partly across the opening of the nail feed-way R³. In the side, and at the forward
end of the nail feeder R there is cut a slot R, (see Figure 23) which is of
sufficient depth to receive the forward side V2 of the nail feeler V and pass by the
same without imparting any movement to the said nail feeler, so that the nail
feeder in its forward movement does not itself actuate or give any motion to the
nail feeler by contact with the forward end V2 of said feeler. The said feeler is
provided with two other arms extending in different directions, V and V. The arm V
having a recess to receive one end of the rod W, hereinafter referred to, and the
arm Vhaving at its extreme end a wedge-shaped pin V. Now if by any chance
the nails in the race-way and in the opening R2 should become exhausted or not
properly fed, so that there is no nail to pass into the nail feed-way, the reciproca-
tions or movements of the nail feeder R and separator S do not affect the position
of the nail feeler, shown in Figure 12, or give any motion to the nail feeler, and
the nail feeler remains in its normal position, as shown in said figure, as the
recess R in the nail feeder R receives the forward end V2 of the nail feeler
therein, and imparts no movement whatever to the said nail feeler, which remains
perfectly stationary, and does not affect or give any movement to the rod W.
Now if a nail is moved into the nail feed-way R³, as herein before described, in
the position shown in Figure 11, it rises on the top of the said nail feed-way by its
collar and its shank projects downwardly in the said feed way, and as the feeder
reciprocates and moves said nail forwardly, its shank comes in contact with the
forward end V of the nail feeler and moves the same from the race-way toward
the position shown in Figure 21, throws the pin V on the inner side of the arm R
extending from the side of the nail feeder R (see Figures 21 and 23) and in the
forward movement of the nail feeder R the arm R7 acts on said pin V6 and
imparts continued movement rearwardly to the forward side V2 and arm V³, and
moves the same into the position shown in Figure 21, with the pin V resting in
the recess V' on the arm R, and from this recess V the pin V easily passes,.
oning to the roundness of its contacting side, in the rearward movement of the
nail feeder R. This rearward movement of the arm V3 is communicated to the
rod W, secured to a vertical arın W1, (see Figures 12, 13, 14, 18, 21, 22 and 24)
having at its upper end a suitable set screw W, and at its lower end said arm Wi
passes through a horizontal arm W3 having a suitable set screw to adjust the
position of the vertical arm W', and at its extreine lower end there is secured a
rectangular shaped plate X, secured to said vertical arm W by a screw X. The
Baid arin W is secured to a horizontal moving block W, located in a suitable
recess W formed between the plates R and R', and its forward limit of movement.
is regulated by a pin W which is adapted in the forward movement of the said
block to contact with a suitable depending plate W' and limit the said forward.
movement, and the rearward movement of said block W is against the tension of
the spring W, secured to a pin W10 on the side R', and at the other end around.
the rear end W of the rod W, and the tendency of the said spring is normally
to draw said block W to said forward position. The motion imparted by the
arm V3 of the nail feeler V, caused by the passage of a nail through the nail
feed-way R³ actuates the forward end V thereof, so that the pin Ve passes inside
the armi R and gives a rearward motion to the rod W, vertical arm W₁ and
block W, so that the parts assume the position shown in Figure 21.
Referring now to Figures 6, 7, 8 and 9, the plate X on the lower end of the
arm W, when no nail has been fed into the nail feedway R³, will be located on
the inner side of the upper end G' of the pin G, as shown in Figures 6 and 7,
and in the reciprocating motion of the slide H, the pawl G is lifted, as shown in
Figure 7, and does not engage a new tooth J but will pass over into the same

page_text: tooth J which it previously fed when a nail had been driven. When, however,
a nail bas been fed and the block W' and the plate X have been moved outwardly
into the position shown in Figure 21, the said plate X passes to the outer side of
the upper end G' of the pin G on the pawl, (see Figures 8 and 9) and holds said
pawl downwardly in the position shown, so that the upper end G' of the pin G on
the pawl passes on the inuer side of the plate X, and the pawl G being held in its
downward position, the finger G in the continued forward movement of the
slide H, engages with the next tooth J' of the ratchet wheel J, and actuates the
same and with it the sprocket wheel J1, (see Figures 8 and 9). This wheel J¹
engaging with the feeding pins F on the heel plate F causes a movement to the
heel plate and heel, and swings said heel into position to receive the next nail to be
driven. It will be seen that as many nails will be driven in the heel as there are
feeding pins F, and it will also he understood that the heel plate F will be turned
as long as a pin Flies in the depression in the sprocket wheel J, the feeding
operation being in a direction indicated by the arrow in Figure 5.
The movement of the sprocket wheel J, caused by the pawl G, begins as the
nail driver starts to ascend, but the jaw separator M does not begin its upward
movement until the pin L' reaches the upper end of the slot M³, when both nail
driver D and jaw separator M continue together their upward movement, so that
by this arrangement the jaws are held open by the said separator sufficient time to
permit the driven nail to leave the passage u", after which, as the jaw separator
moves upwardly with the nail driver, the jaws close to their normal position to
receive the next nail fed forward by the nail feeder R, so that after each nail has
been driven the nail driving mechanism starts its upward movement, followed by
the upward movement of the jaw separator, when the pin L reaches the upper
end of the slot M and the feeding operation of the heel plate takes place
through the pawl G, slide H, oscillating lever E, pitman E' and co-operating
parts.
As shown in Figure 18, the arm S is loosely mounted on the pin So, by means
of the slot S', and the object of thus loosely mounting the arm S on the pin S is
to provide a lost motion of the movement of the upper end S of the arm S, in
that, as the nail pusher or feeder R begins either to move forwardly or to move
rearwardly, due to the oscillation of the arm P, pin P and friction roller P
mounted in the nail feeder R, the effect of such movements is not immediately
imparted to the nail separator S, through the arm S' and pin S, working in the
slot S, so that a certain movement is allowed the nail feeder R before the
movement from the nail feeder R' is communicated to the nail separator S, which
movement exists until the opposite side of the slot S' is brought, by the movement
of the nail feeder R, to a bearing upon the pin S, when the continued movement
of the nail feeder R is communicated through the arm S, bearing on the pin S
and through the pin S working in the slot S to the nail separator S, so that with
the nail feeder R in its forward position, as shown in Figures 10 and 18, as it
begins its rearward motion, it does not effect or produce a forward movement to
the nail separator S until the opposite side of the slot away from the pin S moves
over to and bears on said pin as a center, and then the continued rearward
movement of the nail feeder R imparts through the pin S, at the lower end of
the arm S, a forward movement to the nail separator, and when a forward move-
ment is imparted to the nail feeder R the same amount of forward movement is
given said nail feeder I before its continued movement is imparted to the nail
separator S to withdraw it to its rearward position.
From the above it will be seen that in both the forward and rearward movements
of the nail feeder R there is allowed a certain amount of movement, which is not
communicated to the nail separator S.
Now referring to Figure 11, in which the nail feeder R' is shown in its rearward
position, and the nail separator in its forward position, the forward movement of
the nail feeder R is not communicated to the nail separator S to produce a
rearward motion until said nail feeder R reaches the opening R2, when the

page_text: continued movement forward of said nail feeder imparts a rearward movement of
the nail separator S, and in the continued forward movement of the nail feeder R*,
as it passes by and closes the opening R', the nail separator S is withdrawn from
between the nails to the position shown in Figure 10, and by this means only one
nail at a time can pass into the nail feed-way R in position to he moved forward
by the nail feeder R, as the nail separator S holds the nails in the race-way from
continued downward movement until the nail feeder R has passed beyond the
opening R and is moving one nail forwardly into position to be driven, and as soon
as the said nail feeder R has passed beyond the opening R the opposite end of
the slot S' has reached a bearing on the pin S, and then the continued forward
movement of said nail feeder R is communicated to the nail separator S, which,
through the pin S3 at the lower end of the arm S is withdrawn to its rearward
position, as shown in Figure 10.
Now with the nail feeder R in its forward position and the nail separator S in
its rearward position as shown in Figure 10, the beginning of the rearward
movement of the nail feeder R is lost to the nail separator S, until the said feeder
approaches the opening R leading into the feed-way R, when the opposite side of
the slot S has reached a bearing on the pin S, and the continued rearward
movement of the nail feeder R imparts a forward movement, through the pin S³, to
the nail separator S, which moves between the nails, and owing to its front wedged end
gradually pushes one nail into the nail feed-way R³, as the nail feeder R' uncovers the
opening R into the nail feed-way R, so that this rearward lost motion is provided
that the nail separator S will not move forwardly between the nails and attempt
to crowd or push a nail into the nail feed-way R³ until in its rearward movement
the nail feeder R4 begins to uncover the opening R2 leading into the nail feed-
way R. If this lost motion was not provided, the nail separator S would move
in between the nails and tend to push a nail into the nail feed-way R³ occupied by
the nail feeder R, but by this provision the nail separator S does not begin to
move between the nails until the front end of the nail feeder R, in its rearward
movement, is near the opening R, and as the wedge-shaped end S of the nail
separator S gradually moves between the nails, the nail feeder R recedes and
passes by the opening R as the nail separator S forces a nail into the nail feed-
way R and blocks the other nails from passing into the nail feed-way R³.
Y represents a suitable pin in the table A, (Figure 1) directly in the line of
movement of the nail driver, and over which the various feeding pins F rest in
the revolution of the heel in alignment with the nail driver D to present a solid
bearing for the heel to the blow of the nail driver.
Z represents two bolts which pass through the plates R and R' of the nail
feeding mechanism and secure the same in the position shown, the other ends of said
bolts being secured to a suitable casting on the side of the machine.
The power is started through a vertical rod K of the clutch actuating mechanism
on the side of the machine, and the upper end of said rod may engage with any
suitable clutch mechanism for throwing on or off the power from the driving shaft,
and the lower end of said rod extends below the table to a suitable foot treadle ;
when the last nail has been driven the projection F in the revolution of the heel
plate strikes the knob K and throws the end of the arm K away from its
connection with the clutch operating mechanism K, and the machine is automatically
stopped, or, if desired, the machine can be stopped at any time by the operator
moving the handle K to slip the arm K from connection with the clutch operating
mechanism.
From the foregoing description it will be seen that each nail fed forward by the
nail feeder and driven into the heel, has, in its passage toward the nail driving
mechanism, actuated the nail feeler, and through the nail fecler the governor or
controller of the feeding mechanism for the heel supporting plate, so that after the
bail has been driven into the heel, and as the nail driving mechanism begins its
upward movement, the pawl G on the slide H actuates the sprocket wheel J' to
feed the heel supporting plate and heel in position to receive another nail, so that,
B

page_text: briefly stated, each nail, previous to its being driven, has actuated certain
mechanism, which, after the nail is driven into the heel, causes the operation of
the feeding mechanism and heel supporting plate to expose a new part of the heel
for the next nail.
By means of this invention it is possible for one operator to attend to a number
of machines, as he has only to place the heel in position on the heel plate, start
the machine and leave it. At the proper times, depending upon the passage of the
feeding nails, the feeding of the heel will take place, and when the last nail has
been driven the end F7 of the heel plate will contact with the knob K. and throw
the arm K away from the clutch operating mechanism, and the machine will stop,
so that the machine is automatic so far as driving the nails and stopping when the
work has been done.
The undriven or feeding nail referred to in this specification as controlling the
operation of the feeding mechanism of the heel supporting plate, is to be understood
as referring to any location of a nail after it has been separated from the other
nails in the nail raceway, and is moved along the nail feed-way under the influence
of the nail feeder, or is passing down the drive-way to the nail holding device in
position to be driven by the nail driving mechanism into the heel; that is, it refers
to any location of a nail after it has been separated from the other nails in the nail
race-way up to the time it is driven into the heel.
The drawings forming a part of this application represent views of a machine
in which my invention is embodied, but it will be understood that the same may
be varied and my invention carried out in a variety of ways, and I therefore do
not limit myself to the arrangement and construction shown, as the same may be
varied without departing from the spirit of my invention. Although I have
shown and described my invention as embodied in a heel machine, yet it will be
understood that it is applicable to machines doing other classes of work, into
