We, THOMAS BRINING, of 44 Pontefract Street, Richmond Hill, Leeds,' in the
County of York, Boot Manufacturer, and GEORGE LISTER, of 5, Oakfield Terrace,
Headingley, Leeds, aforesaid, Tanner, do hereby declare the nature of this invention
to be as follows:-
This invention relates to improvements in machinery or apparatus for nailing
boots and shoes after the lasting operation has been performed and the outer sole
has been attached; and its object is to adapt the machine described in the Specification
of Letters Patent granted to the said Thomas Brining, the fourth day of October
A.D. 1887 No. 13390 for feeding and driving hob, nugget, and other nails into the
sole, waist, and heel without removing the last upon which the lasting and rivetting
operations have been performed, thus preserving the boot or shoe in good form
or draft.
According to this invention we employ one or more reciprocating boxes, hoppers,
shoots, and slides of a similar description and respectively mounted upon or; fixed to
framework in a similar inanuer to that described in the above mentioned Specification.
The reciprocating boxes and fixed-hoppers and shoots are provided with suitable slits
or grooves to suit the heads and stems of the nails used. Formed on or attached to
each shoot is a pin or projection for turning or arranging the heads of the nails into
their proper position for gravitating down the covered portion of the shoot to the
slide. In the ends of the shoots, and in the reciprocating slides are cut or formed
holes or recesses of suitable shape for conveying the nails respectively from the shoots
to the slides, and from thence to the tubes communicating with the die box which
is fitted with a pair of removeable dies having a tapering hole to suit the shape of
the head of the nail being used. The tubes communicating with the die box may
be also provided with inclines or their equivalents for turning or twisting the nails
wholly or partially round during their passage through the tubes. The shoots are
also provided with spring pins for admitting one nail at a time to the slides."
Above or on one side of the die box may be mounted upon a suitable horizontal
table or plate attached to the standard or framework of the machine, a wheel, ring
or disc provided with ratchet teeth upon its periphery, and also with any desired
number and rows of holes or recesses suitable for receiving "fitter," "mock clinker,"
or any other nails. The wheel, ring, or disc may when preferred be made in one,
two, or more parta, and when made in two or more portions may be suitably bolted
or otherwise secured together. The nails are fed into the holes or recesses above
mentioned by hand, and, as the wheel, ring, or disc revolves on its bearing or pivot
they are brought over a hole in the table which may be either inmediately over the
die box, or may communicate therewith by means of a tube in a similar manner to
that described in the Specification accompanying the said Thomas Brining's application
When more

Improvements in or relating to Machinery or Apparatus for Nailing
Boots and Shoes.
We, THOMAS BRINING, of 44 Pontefract Street, Richmond Hill, Leeds in the
County of York, Boot Manufacturer and GEORGE LISTER of 5 Oakfield Terrace,
Headingley, Leeds, aforesaid Tauner, do hereby declare the nature of this invention
and in what mannor the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
This invention relates to improvements in machinery or apparatus for nailing boots
and shoes after the lasting operation has been performed and the outer sole has been
attached; and its object is to adapt the machine, described in the Specification of
Letters Patent grauted to the said Thomas Brining the fourth day of October
A.D. 1887 No. 13,390, for feeding and driving hob, nugget and other nails into the
sole waist, and heel without removing the last upon which the lasting and rivetting
operations have been performed, thus preserving the boot or shoe in good form
or draft.

Like parts in all the views are marked with the saine letters of reference.
The standard A, its base a, bearings a ², fixing or bracket a³ and adjustable
bracket a constitute the framework of the machine.

page_text: In the bearings, rotates a shaft A' on which is mounted the friction driving
pulley B and cams C, D, and E. To the front of the standard is fixed a fender or
bracket F to which the nail setting mechanism is attached, whilst to each side of
the standard may be fixed a bracket G, G, each provided with one or more bearings
for carrying the self-feeding mechanisin as hereinafter described.
In order to adapt the machine for nailing the soles (as well as attaching the soles
to the "uppers" of boots and shoes with rivets) with nails of varying shapes and
sizes, as well as to prevent the machine from standing whilst such nails are being
changed or the box refilled two or more sets of self feeding mechanism as hereafter
described may be employed. At Fig. 2, a set is shown in outline on each side of the
setting tool, but at Fig. 4 an arrangement is shown whereby two (or more) sets may
be fixed in step form above each other, each set being capable of being thrown in
and out of action at pleasure so that when one set is at work, the remaining set or
sets is or are stationary. With the exception of the sets being arranged respectively
for the right and left hand sides of the machine, they may be duplicate of each
other, and are marked with the same letters of reference.
A
To each bracket G may be fixed one or more pins or studs g on which is or are
mounted one or more nail boxes H which may be of a similar description as regards
shape to that described in the hereinhefore mentioned Specification, or circular as
shown in the drawings hereunto annexed. In the periphery of the box H is cut or
formed a number of slits or apertures which may vary in size or shape according
to the character of the nail to be used; and in order to regulate the length of the
holes to the varying lengths of nail, an adjustable guage / may be mounted on the
periphery and fixed in position by means of a set screw. In the periphery is
also provided a large opening (covered by a hinged lid and retained in a closed
position by a spring h³) through which the nails are passed to the box.
reciprocating or continuous rotary motion (the latter is preferred) is imparted from
slide M through rod i to arm or lever and friction clutch device as shown.
When it is preferred to impart a continuous rotary motion to the nail box II, the
friction device it is preferred to employ may be of a similar construction to that
which has been used on Sewing and Printing machines, that is to say, a rim or
flange is cast on one end of the box and projects therefrom in a line with the
periphery. Within the rim or flange are placed the jaws, one end of which
is made to impinge against the rim whilst the opposite end of each jaw is inserted
in a recess formed in the boss of the lever i¹. By arranging the jaws at a slight
angle to the centre of the boss and box H and keeping them up to their work by
means of the springs it connected to the projections they are free to move without
operating the box when the lever is raised in the direction of arrow but when it is
drawn downwards the box is partially rotated by the boss of the lever i forcing the
outer ends of each jaw tightly against the rim thus carrying the box round with
them.
Below the box H is an intermediate hopper J fixed to and communicating with
a second hopper 7 which forms a part of the inclined chute L. The chute L may be
placed at such an angle that the nails will by their own weight gravitate down the
channel to the enlarged end thereof.
The chute L is preferably made in two pieces and shaped as shown in the drawing.
On the inner sides of the pieces are provided facings (of the shape shown at Fig. 7)
which are together of a greater thickness than the stem of the largest nail to be
employed; but of a less width than the size of the head of the nail. By this means
a channel is formed for guiding the nails to the enlarged end of the chute.
In some
cases the sides of the chute may also be grooved or recessed as shown at Fig. 35.
In order to allow the nails to get into the required vertical position for passing down
the channel after they escape from the intermediate hopper J, the chute is made
hopper shaped for a portion of its length until it reaches the incline (x, below the
latter the channel in the chute is protected by a suitable cover placed a little
distance, say about a sixteenth of an inch, above the upper face of the chute.
In some cases it is necessary to turn the heads of "fitters" or other similar nails

page_text: partially or wholly round as they gravitate down the covered portion of the chute for
arranging then in proper position for insertion in the sole, for this purpose a pin or
projection shown at Fig. 35 may be formed on or fixed to one of the portions of
the slide in any convenient distance between the hopper and enlarged end of
chute 1*.
In some cases the incline lx may be dispensed with and the chute may be in one
continuous line from the hopper J to the enlarged end as shown at Fig. 2.
and
The nails after passing down the chute come in contact with the projection
are prevented from passing along the passage communicating with the hole by
means of the arm 18 of the curved and adjustable lever le pivoted to a pin 10 fixed in
the recessed or cut away portion of enlarged end. The lever may be adjusted
by means of the set screw working in its arm and it may be kept up to its work by
means of the spiral spring. As soon as a nail reaches the projection of the
enlarged end. a portion of the nail head covers the projection and end of lever l
and rests there until acted upon by a spring pin or piece working in a groove or
slit whilst its free end is carried in bearing 15 fixed to the chute as shown at
Figs. 8. 9. 10 and 11. To convey the nails one at a time to the hole motion is
imparted from the slide M to the spring piece through bell crank lever pivoted to
block m.
When the spring piece 13 is pressed forward in the direction of the hole b
the stem of the nail is carried forward until it comes in contact with the arm 18,
(the head of the nail meanwhile slides upon the top of the projection and enlarged
end ) when by the continued forward motion of the spring piece the arm " is
pushed back within (or nearly so) the hole and a free passage thereby provided
for the nail to be delivered into the hole and from thence to the dies (through a
suitable tube) to the setting tool. When it is found necessary to again reverse or
arrange the heads of the nails for dropping into the conducting tube in the required
position a pin or projection may be provided in the passage at the entry of the
hole . The slide M is carried in a block m bolted to the standard. An intermittent
reciprocating motion is imparted to the slide M from cam Con driving shaft A'
through runner m', lever m³, shaft m³ (carried in bearing ³), lever made in two
portions mm², stud or projection me fixed to the opposite end of the slide to that at
which the rod is connected for reciprocating or partially rotating the nail box H
whenever the slide Mis operated. In order to be able to throw the slide M readily
in and out of action the upper portion m of the lever made in two parts is keyed to
shaft m³ and is provided with a male portion of a V slide. On this Vn portion
slides the lower parts of the lever and in its normal position its lower end is kept
clear of the pin me by a spiral spring mu fixed to a pin m' working in a slot m³ at
the back of the lever. But when it is required to bring the slide into action the lower
portion ms is drawn downwards by handle me until spring pin mo passes into a hole
or notch in the upper portion m' and holds it there until the operator withdraws the
pin mo when spring m immediately raises the end clear of the pin mo. When more
than one of these double levers are keyed onto shaft they may be arranged one
behind the other and of varying lengths, each double lever having a certain amount of
lost motion in order to permit of them being actuated by the same cam, and at the
same time for the slides to have an equal amount of traverse. After the slide hás
been drawn towards the setting tool for actuating the spring piece 13 through lever Po,
immediately the end m³ of the lever commences to recede, the spring m12 (which has
been expanded by the operation described) commences to contract for returning the
slide to the position shown in the drawings.
Each chute may be attached at one end to the block m. and at or near the hopper
end thereof by a bracket 120 to the standard A. In the drawings we have shown the
slides and tubes and other parts connected therewith suitable for receiving and
conveying a round headed nail to the dies and setting tool, but when it is required
to convey square or other headed nails the tubes and other parts will require to be
shaped accordingly. The tubes communicating with the die box may be also provided
with inclines or their equivalents for turning or twisting the nails wholly or partially
round during their passage through the tubes.

page_text: In order to readily clear the month of the conducting tube should it in anyway
become choked, the front outor portion of the enlarged end of each chute may be
hinged to its side as shown (" at Fig. 11, and retained in a closed position by means
of a spring catch (".
In order to supply nails which are usually known as "fitters" (that is with a
tapering head), mock clinkers or other nails, on a suitable plate to may be mounted
a horizontal ring T (made in two parts bolted together) provided with ratchet teeth
on its periphery in which a pawl t engages. The pawl t is mounted on a bracket t¹
pivoted to a bracket bolted to the standard A, and is capable of receiving a recipro-
cating motion from a cam E on the driving shaft through lever pivoted at t
to bracket (bolted to standard A), connecting rod to adjustably connected to [
lever which is also pivoted to bracket t In the ring T are also cut any desired
number of holes to suit the nail heads. The nails are fed into the holes or recesses:
above mentioned by hand, and, as the ring revolves on its bearing plate they are'
brought over a hole in the plate t which may communicate with the dies N by
means of a tube 12 in a similar manner to that already described. When more than one
row of holes or recesses are provided in the ring, then a separate hole in the plate and
a communicating tube for each row will require to be provided, or the ring, may be.
imounted upon an adjustable pivot or bearing.
But when preferred the ring T may be dispensed with and a separate slide which
has previously been filled by hand with pails may be hooked on to the chutes (previously
described) and allowed to empty itself through a suitable aperture.
The nails after passing through the hole enter a tube 21 by which they are con-
ducted through a hole n in nail guide block n' to the dies N bolted to the fixing or
bracket which in turn is bolted to the slide carrying block m. This guide is
provided with a number of holes n (corresponding in number with that of the tubes
and the chutes L employed) and a recess in which is inserted the two dies N, N,
which are held in position or face contact by means of the flat spring pieces n³ nº.
In each of the dies is a vertical semicircular tapering hole n' as shown at Figs. 26
and 27 the longer and larger portion of which is made at its lower end to taper into
the smaller one.
The upper portion of the hole n' is of such a diameter that the heads of the nails
can pass readily through it whilst the smaller diameter is just large enough to receive
the shank, and hold it there until the fixing tool or ram descends to force open the
dies and to drive in the nail. The fixing tool P is carried by a nipple pin the end of
the piston rod pl a portion of which works within a cylinder p2 which is fixed to the
projecting barrel of the fender F; this barrel also forms the lower bearings for
the piston rod. On the pistou rod and within the cylinder is a piston p between
which and the upper inner portion of the cylinder is fixed a spiral spring pas
shewn at Fig. 2.
In order to impart the required pressure to the setting tool P a screw is passed
into the top of the cylinder p2 and is locked in position by a nut p7. The screw p
also forms a bearing for the upper part of the piston rod. The stroke of the fixing
tool P is adjusted by means of the lock nuts ps shewn at Fig. 2. and to prevent any
rebound of the rod when the fixing tool has driven in the nail a recess is provided in
the top of the screw which is filled with india rubber or elastic packing p³.
.
An intermitting reciprocating motion is imparted to the fixing tool by means of a
cam D mounted on the end of shaft A'. The cam raises the tool to its highest point
thereby compressing the spring p, but as soon as this has been reached, the spring
causes the tool to descend with such force that in falling it passes through the dies
and when it comes in contact with the taper parts of the hole it forces them open
sideways, and in its further progress drives the nail into the article being operated
upon. It will be observed that whilst the fixing tool is doing this the nail is guided
aud kept in a vertical position until the tool has reached its lowest point and com-
pleted its work. The fixing tool P may be arranged that its end when at the highest
point will not pass out of the hole n³ in the block n' carrying the die box..

page_text: The last (upon which the upper has been lasted) as it leaves the lasting machine
is mounted on a pillar Q so that its toe may rest upon a second pillar Q These
pillars are mounted in adjustable bearings upon a sliding framing q' provided with
the universal joint q by which it is connected to the supporting rod q³. The rod is
passed through the bearing formed in the end of bracket a' and connected with its
lowest end to the weighted treadle R pivoted to the standard A. at R¹. In order to
adjust the last to any desired position the upper portion qt of the pillar Qis pivoted
to its lower portion 7' and the two parts are kept in the desired position by means of
a screw q operated by a handle. It will be readily seen that by the combined action
of the universal joint and sliding table the boot can be manipulated in any desired
direction under the setting tool.
In order to feed or traverse the boot sole the required distance or pitch of the nails,
a horizontal shafts is carried in suitable bearings in the bracket. On this shaft is
mounted, with one of its faces impinging against the dies N; a feed wheel S, and one
the opposite end is mounted a friction wheel, and clutch arrangements (of a some-
what similar arrangement to that described for the nail boxes ;) and a double ended
lever 82, one end of which is connected with the tappet rod 8 (which conveys the
required intermittent motion to the feed wheel whenever it is acted upon by the
cam D) whilst the opposite end is kept in facial contact with a sliding piece s
(carried in bracket 30, and armed with an adjusting screw and lock nut 8) by cam sx.
The sliding pieco and cam are held in contact by spring s. Whenever the cam D
depresses the rod the jaws of the friction clutch arrangement are forced or wedged
against the rim st and thus carrys the feed wheel round for feeding purposes. 81 is
a set screw for regulating the stroke of the lever s and of the feed wheel.
In order to regulate the distance of the nails from the edges of the soles in the
bracket or fixing, n² is attached or formed a V slide win which a plate warmed with a
runner slides, the plate u is provided with a recess 3 through which au adjustable
distance guage piece, (the sides of which are inclined or taper in various directions
as shown at Fig. 32) is passed, and against which an adjusting screw u³ is kept in
contact by an india rubber or other spring . The block is mounted upon a
screw in such a manner as to be capable of being turned axially thereon
without altering its height, but when it is required to raise or lower the block
to suit various sizes or kinds of nails, the screw is passed into the boss us
(which acts as a nut) of the bracket u, carried on the V slide u
In order that nails having heads of various sizes may be easily and readily
driven into the sole at varying distances from its edge, the block u is provided
with sides more or less at an angle whereby provision is made for increasing or
diminishing the distance of the runner u' from the edge of the feed wheel S
according to the shape and height of the face of the block that may be brought
into contact with the head of the adjusting screw u³. But when it is required to
put three rows in the centre of a boot sole (in a straight line or an arc) the
bracket and parts connected therewith are thrown back by withdrawing the
spring pin from its retaining hole by lever and pushing the bracket back
on its slide
10
The required rotary motion for actuating the moving parts of the machine is
imparted to the shaft A in a similar manner to that described in the hereinbefore
mentioned Specification, that is to say --On the shaft A' are mounted a pulley B
(which is keyed thereon) and a loose and sliding friction clutch or pulley (pro-
vided with a slightly coned end) round which is placed a belt 6. To the friction
clutch pulley b is imparted a rotary motion from any convenient source through
belt 6 and when the coned end of the clutch pulley b is disengaged with the
pulley B, the said clutch pulley b is free to revolve on the shaft without actuating
it or the moving parts of the machine. When it is desired to convey a rotary
motion to the shaft A' for actuating the nail feeding, driving, and other moving
parts of the machine, a sliding motion is imparted to the clutch pulley 6 (in the
direction of arrow) from the weighted treadle 62 (pivoted to standard at6x) through

page_text: connecting rod 0, lever and shatt b which causes the coned end of the friction
clutch pulley b to be brought into gear (frictional contract), as shown in the drawings,
with a recess formed for its reception in the fixed pulley B thereby imparting
motion to the shaft. At the same time that the treadle is depressed for operating
the friction clutch pulley b the end of a bracket fixed to the lever 65 is removed
from a notch 68 formed in the periphery of the flanged projection of the fast pulley B
which permits of the shaft A' revolving as soon as the coned end of the friction
clutch pulley b comes in contact with the fast pulley B. But as soon as the operators
foot is removed from the treadle the clutch bis by the weight on the treadle thrown
out of gear with the pulley B and at the same time the end of the bracket b' fixed to
lever 65 is raised and made to pass within the notch bs in the periphery of the flanged
projection of the fast pulley B, thus stopping the rotation of the shaft A' in one given
position.
The action of the machine is as follows:-'
-The boot after being lasted is placed with
its last on the jack Qand adjusted to the required height and position under die box.
Ordinary nails having been placed in the boxes H (or rim T) aro fed to the dies in
manner herein described.
The runner having been adjusted to the required distance the machine is then
set in motion by depressing the treadle bo which brings the friction clutch b (by means
of rod and bell cranked lever b) into contact with pulley B when the cams C, D, E
are caused to rotate for operating the boxes H, slides M, rim T, and for raising the
driving tool P to its highest position. When this point has been reached it is per-
mitted by the shape of the cam and the expansion of the spring to descend with
sufficient force to open the dies N and drive the nail into the sole.
During the rotation of the cam D its perimeter comes in contact with the upper
end of lappet rod which by means of friction clutch s'shafts and feed wheel S
traverses the work forward the required distance between the nails, which distance
may be varied or adjusted by set screw 812.
When the operator removes his foot from treadle 62 the machine is speedily stopped
by the arm 6 passing into the groove or notch b³ in the rim of the flange of
pulley B.
The above described improvements may be combined with or substituted for parts
of the machine described in the herein before mentioned Specification and adapted to
rivet the sole to the uppers of boots and shoes.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is:
1. The manufacture and use of a machine substantially as herein described for
nailing the soles and heels of boots and shoes, in which the nails are placed in a box
and passed down a chute and fed one at a time by mechanism substantially as described
to a tube, or direct from a ring such as T, to the dies and held in position for being
driven into the sole or heel by a setting tool operated as described.
2. The combination with a nail setting tool such as P and parts connected there-
with for operating the same substantially as herein described, of an arrangement
whereby one or more slides such as M is or are caused separately to operate a corre-
sponding number of nail receiving boxes such as H and parts connected therewith
substantially as herein described, for presenting one nail at a time to the action of the
setting tool.
3. The combination with a nail setting tool such as P operated substantially as
herein described, and with one or more nail boxes such as H. (and parts connected
therewith for operating each box separately) arranged singly or in groups on each
side of said setting tool, of a plate armed with runner and parts connected
therewith for adjusting the distance of nails from the edge of the sole.
4. The combination of a setting tool such as P and parts connected therewith with
one or more nail boxes such as H and parts connected therewith for operating the

page_text: same and conveying the nails one at a time to the setting tool, ring such as T and
mechanism such as herein described for operating the same, as and for the purposes
set forth.
