Year: 1859

page_text: LETTERS PATENT to Lyman Reed Blake, of the State of Massachusetts,
of the United States of America, for the Invention of a "NEW AND
DISTERY AD IMPROVED MACHINE FAR SEWING & SOLF ON A BOOT OR SHOP"
COMPLETE SPECIFICATION filed by the said Lyman Reed Blake at the
Office of the Commissioners of Patents, with his Petition and Declara-
tion, on the 3rd May 1859, pursuant to the 9th Section of the Patent
Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, BE IT
KNOWN, that I, LYMAN REED BLAKE, of the State of Massachusetts, of the
United States of America, have made an Invention of a "NEW AND USEFUL
OR IMPROVED MACHINE FOR SEWING A SOLE ON A BOOT OB SHOE," and I do hereby
declare that the nature of the said Invention, and the manner in which it is
to be performed, or its construction and mode of operation, are herein-after
fully described, reference being had to the accompanying Drawings, of which
Figure 1 is a front elevation of such machine; Figure 2, a rear elevation of
it; Figure 3, a longitudinal section, taken through its needle and needle

page_text: carrier; Figure 4, a transverse section, taken through the needle and the arm
for supporting a shoe while being sewed.
The nature of the said Invention consists, first, in arranging the shoe rest
on the end of an arm or projection to extend from the table or supporting
frame of the machine, and be capable of entering the shoe and introducing the
said rest into the toe, and other part or parts of the interior of the shoe, in
order that an outer sole may be stiched or sewed upon the inner sole and
upper or upper leather of the said shoe or boot.
My Invention further consists in arranging the thread passage or the looper
or both within, or so as to operate with the shoe-supporting arm, substantially
as herein-after described.
Also in the application of the feeding mechanism to the needle or its carrier,
so as to enable the said feeding mechanism to be revolved around or with the
said needle and its carrier, in order to change the direction in which the shoe
is to be fed along while it is in the process of having an outer sole sewed
upon it.
In the Drawings, A denotes the table or stand of a chain-stitch sewing
machine. On and above the said table an arch B, composed of two vertical
columns a, a, and an arch bar extends, as shoun in the Drawings. Within
the said arch there is a curved bar C¹, which at its middle supports and has
extended downward from it the needle carrier C, from whose lower end a
hooked needle D projects, as shown in the Drawings. The said bar C¹ slides
up and down in guides in the columns a, a, and at its opposite ends has two
connecting rods E, E, jointed to it, and extended downward respectively to two
bell cranks F, F, of a driving shaft G, arranged below the table of the
machine, as shown in Figures 3 and 4. While such shaft is in revolution, a
reciprocating motion upward and downward will be imparted to the needle
carrier and needle. The said needle works through a rest or supporting
surface c of the upper part of a long curved arm H that projects upward from
the bed or table A, in manner as shown in the Drawings, and should have
such a form as to be capable of entering a shoe so as to carry the rest c into
the toe part, as well as any other part of the interior of it. The said curved
arm H carries at its front end, and directly underneath the rest c, a looper d,
which consists of a small pulley formed in top view, as shown in Figure 5,
wherein the said pulley is represented as constructed with a small thread
notch e extended from its eye f. The said looper is supported within the end
of the arm H, so as to be capable of rotating or being partially rotated around
the needle, while the said needle may extend into and through the eye of the
looper, such eye being placed in the path of the needle. In order to impart to

page_text: the arm.
said looper such a movement as will cause it to lay the thread around the
needle in such manner that the said thread may be seized by the hook of the
said needle, a belt or band G' is extended around a groove in the circum-
ference of the pulley, and from thence is carried through grooves h, h, made in
the sides of the arm H, as shown in Figures 6 and 7, which are side views of
In its passage through the angles of said grooves, the said band may
be carried around guide pullies i, i, and it should have its two ends passed in
opposite directions around the circumference of a drum or pulley I, arranged
underneath the table A, as shown in Figure 4 and also in Figure 8, which is
a transverse section of the machine, such section being taken so as to exhibit
the mechanism for operating the said drum. The two ends of the band are to
be attached to the drum, which is to have an intermittent reciprocating motion,
or.such a suitable movement imparted to it as will cause the band to operate
the looper in the manner necessary to enable the needle to perform chain-
stitch sewing. From the shaft of the drum I (see Figure 8), an arm or crank k
extends downward, and has a connecting rod jointed to it. The said rod
slides on the driving shaft G, and has a stud or roller n projecting from one
side of it into the groove of a cam K fixed on the said driving shaft. By
means of such arm or crank k, the connecting rod 1, the stud n, and cam k,
the proper motions can be given to the drum I. The thread for the needle is
wound about a bobbin L, arranged as shown in Figures 2 and 4; from thence
such thread, by suitable guides p, p, is led along in the curved arm II and through
a tension spring q applied to the arm, as shown in Figure 4. After passing
through the said tension spring, the thread is carried upward through the notch
e of the looper d.
The needle carrier C extends through a cylindrical block M, which is
arranged as shown in Figures 1, 2, 3, and 4, and supported by a cross bar N
of the arch E, so as to be capable of being turned around in and concentrically
with the needle carrier. A friction spring or brake o is extended from the
bar N, and made to bear against the curved periphery of the block M, such
spring being for the purpose of maintaining the said block or the feed wheel
thereof in any desirable position in which it may be placed. A handle P
extends from the lower end of the block and below the cross bar N, and is for
the purpose of enabling a person to rotate the block as occasion may require.
The feed wheel or feeder R by which the shoe is moved along on the curved
arm H during the process of sewing a sole to the shoe, is supported by a
slider extended downward from the block M and applied thereto, so as to be
capable of sliding up and down therein. A coiled spring s extending around
the needle carrier, as shown in Figure 4, acts on a projection from the said

page_text: slider, and serves to press the feed wheel downward upon the sole of the shoe.
The said feed wheel is furnished with a ratchet t which engages with a pawl u
carried by a lever v, whose fulcrum w is supported by a strut x extending
downward from the block M. The said lever by means of a connecting rod y
is connected with the lower end of a slider z, which plays freely in a longi-
tudinal direction within the block M, or is arranged therein as shown in
Figure 9, which is a section of the block, the needle carrier, and the said
slider. A groove al is formed in the slider z, and receives a stud b¹ extended
from the needle carrier. A regulating screw c¹ passes down into the slider z
and endwise into the groove a¹. During the descent of the needle carrier the
stud b¹ strikes the lower end of the groove a¹, and forces the slider down-
ward; so during the upward motion of the needle carrier the stud b¹ will be
brought in contact with the lower end of the screw c³, and will elevate the
slider z. These motions of the said slider will produce the required motion of
the lever v, in order to effect the necessary intermittent movements of the feed
wheel.
In connection with the needle what is termed a "rest cast off," d¹ may be
employed. Such is a well-known device in common use in some chain-stitch
sewing machines, particularly those employed in sewing leather.
In the operation of this machine, the shoe to which a sole is to be sewed is
to be placed on the arm II, and with the sole upward and the arm extending
into the shoe, the feed wheel being made to rest on the sole. On the
mechanism being put in action the shoe will be moved or fed along on the
rest c, and the sewing of the sole to the upper leather, and the insole of the
shoe will be performed by the needle and the looper, or the same and the rest
cast off.
In order to change the direction of the feed or movement of the shoe on
the rest c, the block M should be turned around more or less, so as to change
the position of the feed wheel in such manner from time to time as may cause
it to feed the shoe along during the process of performing the sewing of the
sole to it.
What I claim as my Invention is the arrangement of the rest c of a sewing
mechanism or its combination with an arm H, of such form as to be capable
of entering a shoe and introducing the said rest into the toe and other part or
parts of the interior of the said shoe, in order that an outer sole may be
stitched or sewed upon the inner sole and upper of such shoe.
I also claim arranging either the thread passage or the looper or both
within, or so as to operate with the shoe-supporting arm H, substantially as
described.

page_text: I also claim the application of the feeding mechanism to the needle or its
carrier, so as to be capable of being revolved around or with the same, sub-
stantially in manner and for the purpose as specified.
In testimony whereof I have hereunto set my signature and seal, this
12th of April 1859.
