Improvements in Shoe Slugging Machines.
I SOLOMON MARCELLA CUTTER of No. 468 Valier Street in the City of
Quebec in the District and Province of Quebec Dominion of Canada Mechanical
Engineer do hereby declare the nature of this invention to be as follows :-
This invention relates to machines for automatically supplying loose nails from
a reservoir or hopper to a nail guiding throat from which the nails are driven by
a reciprocating driver and has for its object to provide a more efficient, durable
and less complicated machine than has hitherto been produced and further to
provide a novel and improved stock feeding device which co-acts with the slug,
driving parts to secure the better insertion of the slug.
The invention consists firstly of the combination with the slug driver, a partly-
formed slug receiving throat, or guide-tube, and means for supplying slugs thereto,
of a work feeding awl adapted to enter the stock at a point out of line with said
throat to move to within the axis of said throat and be withdrawn from the said
stock and complete the formation of said throat and means for actuating the
said awl. A second feature of the invention consists in the combination of the
slug driver the slug supply, a moveable raceway provided with a slug releaser at
its lower end, a slug receiving throat or guide tube proper diminished in height to
allow the nose of the raceway carrying the slug to project in and place the slug
directly over the throat and in the axis of the driver and having a bearing plate
at one side thereof, and a combined reciprocating detent and holder, the former
operating the slug releaser and the latter acting in conjunction with said bearing
plate to hold the slug during the withdrawal of the raceway. A further feature
of the invention consists of a flexible or yielding connection intermediate of the
combined reciprocating detent and holder and the cam and lever mechanism for
operating the same.

Improvements in Shoe Slugging Machines.
I SOLOMON MARCELLA CUTTER No. 468 Valier Street in the City of Quebec
in the District and Province of Quebec Dominion of Canada, 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:
This invention. relates to machines for automatically supplying loose slugs or
nails from a reservoir or hopper to a guiding throat from which the nails are
driven by a reciprocating driver, and has for its object to provide a more efficient,
durable, and less complicated machine than has hitherto been produced, and, further,
to provide a novel and improved feeding device which co-acts with the slug driving
parts to secure the better insertion of the slug.
The invention consists in the several improvements which I will now proceed to
describe with reference to the accompanying drawings:

Figures 11 and 12 are face views, partly in section, of the parts shown in
Figures 9 and 10;
Figure 13 is a horizontal section on the line Figure 12 of the front portions
of the head, and
Figure 14 is an elevation of the right hand side of the head portion of the
machine.
A is the upper end of the standard or pedestal of, the machine, its lower portion
not being shown, as the invention is confined solely to the parts carried by the
head portion or frame B, which is bolted to the said.standard.
CCC² are three standards formed in one with or secured to the frame B and
projecting up from it. The end standards C C2 carry the driving shaft D and the
other standard C¹ carries the lever for operating the slug driver.
The shaft D has mounted upon it a fly wheel D' and fast and loose pulleys D2 D3,
a cam E for operating the slug driver, a double cam E' E' for operating the work
feeding mechanism, a pulley F and band f for rotating the nail or slug reservoir F
which may be of any usual construction and a grooved roller G for operating the
combined slug holder and releaser.
The slug driver H which may be of the usual form is secured to a cross head or
dovetailed plate H¹ Figures 1 and 5 working in a vertical guideway formed by
face plates HH2 screwed to the standard C2, a positive up and down. motion being
imparted to it through a lever J, pivoted in an arm C³ extending from the
standard C and having its inner end forked to connect with a block J', which is
arranged to slide in vertical guideways in the standard C', and to carry a roller j
which works in the groove of the cam E, the lever J being connected at the other
end by a link J* with the cross head H¹,
H* H* are additional face plates covering the operating parts in the lower
portion of the standard C2 the plate H forming one side of the vertical throat for
the nails or slugs.
The raceway or guide K along which the nails or slugs travel from the
reservoir F is constructed and operated to conduct the said nails or slugs to a
position directly above the vertical throat or tube O and in line with the axis of
the driver. This raceway consists of a solid inclined bar (Figures 2 and 3) having
a base block or foot K', provided with dovetail edges k to fit and slide to and fro
in corresponding guideways formed on the base plate of the frame B, the bar
being grooved centrally in its upper surface to afford a passage way K' for the
slug bodies or shanks of the nails.
Two adjustable cover strips k² are secured on the bar K at the required
distance apart to support the slugs or nails by their heads while allowing them.
free passage. These cover strips project forward beyond the lower feeding end of
the raceway body, so that when the raceway is moved forward the slug at the
extreme end thereof will be directly over the throat O and beneath the driver H.
L is a yielding slug releaser in the form of a lever pivoted at L' to the top of,
the cover strip and bent so that one portion will lie flat on the upper surface of
the cover strips k² and present a pointed finger across the extreme end of the
l

page_text: raceway passage another portion being turned down over the side of the raceway
and receives the pressure of a coiled spring against its end, it has also a down-
wardly and forwardly projecting ear or lug 12, by means of which by an extension
from the slug holder coming in contact therewith, as will be hereinafter explained,
the lowermost slug is freed. An adjustable protector strip M, extending about
half way up the raceway, is also attached thereto, as shown in Figures 2 and 3, to
prevent the slugs or nails from jumping out.
This
The forward movement of the raceway is effected by means of a lever N
Figure 1 pivoted at n to a bracket N₁, projecting out from the rear of the
standard C2 and having one end pivotally connected at n' with the raceway and
the other end carrying a roller n², working in the groove of the roller G.
roller is preferably composed of two parts g g¹ Figures 6 and 7 one of which g has
formed in one with it the sleeve portion G², required for securing it to the shaft,
the other part g' being secured to the said sleeve portion. The inner faces of
these sections are correspondingly shaped to present an inclined groove or guideway,
the rotation of which will impart reciprocal inovement to the lever N. Adjustable
studs g² g² are screwed through the section y as shown in Figures 6 and 7, so that
their ends will project into the groove and produce a shaking or tremulous motion
in a longitudinal direction in the raceway at the proper time for the delivery or
release of the lowermost slug or nail.
The slug holder proper consists of a bar or finger P (Figures 11, 12 and 13)
which is an extension from a plate S working horizontally in the side of the head B,
the lever arms P1 P2 pivoted in the bearing P³ Figures 1, 4 and 5, and the cam Q
being its operating mechanism. The bar P holds the slug firmly between its end
and the block p forming the upper. portion of the right hand side of the throat.
In order to accomodate different sizes of slugs the bar S (see Figures 4 and 5) is
yieldingly connected with the lever arm P² by means of an arm P projecting from
the lever arm P2 a stud s on the said lever entering a slot s' in the plate S; a rod s²
pivotted to the end of the plate S and passing through a hole in the bent end of
the arm P' and a coiled expansion springs acting between the end of the arm P*
and the pivoting shoulders of the rod s².
S is an extension from the finger P, but out of line of the slug driver and slug,
and moving in front of same for the purpose of operating the yielding slug releaser
or lever L as before described.
The feeding mechanism consists of the vertical awl V, formed on the inner end
of a horizontal shank or slide V₁ carried in a groove in the foot portion V2 of a
bar V³, located in an inclined guideway or passage way V in the framework-
head B, which guideway is wider than the bar in order to allow of a slight lateral
movement of the bar therein, as will be more fully explained in the operation of
the machine. The upper end of the bar V3 is attached to the free end of an
arm V, (see Figure 5) fixed by set screws on the forward end of a
shaft Ve
(Figure 14), running parallel with the main driving shaft D and being
carried at the front and rear ends, respectively, by an arm c, projecting from
standard C, and an arm or extension c¹ from the standard C. The shaft V is
encircled for the greater part of its forward length by a sleeve W, as shown in
Figure 14, and on this sleeve are fixedly set, first, an arm W', carrying at its
lower end a pusher bar or rod W* for acting on the foot of the bar V3, as will be
fully explained hereinafter, the arm W₁ being connected with the said bar V³ at
its lower end by retractile spring W³; secondly, a collar W4, to which is attached
one end of a spring W, coiled around the sleeve between the collar and the arm c
and to which latter its other end is attached; and thirdly, an arm Wo, fixedly set
in place and carrying a roller w on its free end to bear on the periphery of the
part E of the double cam E¹ E2, a second arm V' being fixedly set upon the
shaft Ve beyond the end of the sleeve W and carrying a roller » ou its free end
to work in a cam shaped groove e² (Figure 8) in the part E2 of the double
cam E E
When the raceway is in its forward position, as shown in Figure 9, with the

page_text: slug directly over the throat O, the holder P through the lever arms P1 P2 and
cam is thrown forward to grip and hold it fast between its end and that of the
block p, and the slug is freed from the finger by the extension S¹ having moved
a stop out of the way of the slug, so that it only remains to withdraw the raceway,
which is done by means of the groove of the roller G, which acts through the
lever N to draw the raceway back a sufficient distance to free the slug from its
end, leaving it held between the holder P and the block p when the driver H
descends to drive the slug down the throat into the work, the indentation in which
latter caused by the feeding-awl facilitating the entry of the slug.
While the slug is being driven the awl V forms the lower right hand side portion
of the throat O, as shown by the dotted lines in Figure 11 and simultaneously with
the upward movement of the driver H the awl moves to the required point over
the work where the next slug is to be inserted and it is then driven down into the
work and carries it to its position under the driver H, after which it is withdrawn
from the work, leaving a hole for the reception of the slug, and takes the position
shown by the dotted lines to form the lower portion of the right hand side of the
throat O, as before mentioned. This motion of the awl V is secured by the
cam E, (acting upon the lever W, sleeve W, arm W¹, and. pusher-rod W2)
the groove e² in cam E2 (acting through lever V', shaft V³, arm V³, and bar V³
and the springs W3 W, the spring W3 serving to draw the bar V³ in the required
direction (the rises 2 and 3 of the cam E¹ being arranged to regulate the several
movements) and the spring W³ serving to hold the roller on arm W against the
periphery of cam E¹. An adjusting screw w³ in the framework head B is
provided to regulate the spacing of the slugs in the work by stopping the move-
ment of the bar V3 at different points. The spring W³, in combination with the
vertical surface or notch Y on the side of the bar V³ and the adjusting screw w³,
also provides that while the bar is in an inclined position the downward movement
of the awl V shall be perfectly vertical.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
