COMPLETE SPECIFICATION.
An Improved Lamb's Wool or Slipper Sole.
I, SAMUEL BORCHARDT, Manufacturer, of 325 East 103rd Street in the City
of New York, in the County and State of New York, United States of America,
do hereby declare the nature of my 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 an improvement in lamb's wool or slipper soles, and
especially to an improvement in that class of soles adapted to be attached to an
upper made by crocheting or equivalent means, and the object of this invention is,
to provide such a sole which will not require binding, and in which the bottom will
be in one piece; and furthermore, in which the stitching ordinarily employed for
attaching the sole to the soft upper surface may be entirely omitted. Another
object of the invention is to provide the margin of the sole with a draw string,
whereby it may be crimped around the upper surface of the sole, forming an
upwardly extending flange for attachment to the upper, the flange being materially
strengthened by the aforesaid draw string, and likewise being a medium for attach-
ment between the upper and the sole if desired; and a further object of the
invention is to provide a stitching on the outer flanged portion of the sole, which
will greatly aid in attaching the upper of the slipper and will likewise hold the
draw string, cord or other article that may be employed for holding the flanged
portion of the sole in position. A further object of this invention is to provide a
means whereby the flanged, portion of the sole at the instep will be made to conform
to the plan of the sole, the medium for this purpose being entirely concealed by the
instep covering for the sole.
The invention consists in the novel construction and combination of the several
parts, as will be hereinafter fully set forth and pointed out in the claims.
Reference is to be had to the accompanying drawings forming a part of this
specification, in which similar characters of reference indicate corresponding parts
in all the figures."

Figure 1 is a perspective view of the improved sole, a part of the upper facing
being broken away at the instep;
Figure 2 is a longitudinal vertical section thereof;
Figure 3 is a view of the heel portion of the sole ;
Figure 4 is a transverse section through the sole; and
Figure 5 is a perspective view of the toe portion of the sole, illustrating a slight
modification in its construction..
The sole consists of a stiffening strip 10 of pasteboard, cork, or other desired
material, and an upper facing 11 of lamb's wool, Canton, flannel, or other soft
material which is usually cemented to the stiffening strip 10, but may be attached
in any other desired manner. The material of the sole is completed by the
addition of a bottom strip 12, made preferably of leather and in one piece, but it
may be made from other suitable material. All the strips are given the necessary
shape, but the bottom strip. 12 is wider than the others and is provided in its
margin with a draw string, cord or tape 13, or the equivalent of the same. The
bottom or leather strip is cemented or otherwise secured to the stiffening strip 10,
and by manipulating the draw string, the ends of the string preferably meeting at
the heel, the marginal portion of the bottom or leather strip will be gathered
upward around the finishing and inner strip, completely concealing and protecting
their marginal surfaces.

page_text: In order that the flange thus: formed by drawing in the margin of the bottom
strip 12 may conform perfectly to the plan of the shoe or slipper sole, a lacing 10
of any suitable material is extended from the instep portion of the said flange from
one side to the other of the sole, the said lacing being located beneath the upper
facing 11, and is therefore entirely concealed.
The draw string or the equivalent used may be placed in a hem formed in the
margin of the bottom strip of the sole, or, as illustrated in Figure 5 of the drawings
the string or cord may be passed through loops 14; made by proper stitches properly
placed, or any equivalent may be employed as a conductor for the string. If in
practice it is found desirable a series of apertures 15 may be made in the bottom
or leather strip, adjacent to the draw string, or more properly in the flanged portion
of the bottom, as shown in Figure 5, in order that a comparatively blunt, needle
may be passed through these apertures in attaching the upper to the sole.
It is evident that the upper inay be secured to the sole by stitching or otherwise,
attaching it to the draw string or to the enclosure of the said string, and that the
marginal portion of the sole is materially strengthened by the aforesaid draw string
or its equivalent, enabling the upper to be inore readily and securely attached to
the sole than under the ordinary construction of the latter article. Furthermore it
is obvious that there is no necessity of stitching through the bottom of the sole,
which stitching is usually quickly worn out, when the sole then separates from the
upper or from its several parts.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is,
1. A lamb's wool or slipper sole, constructed substantially as herein shown and
described.
2. A lamb's wool or slipper sole having its bottom section wider than the other
sections and provided with a tension device near the marginal portion of the
bottom section, which tension device acts in the capacity of a draw string, substantially
as described.
3. A lamb's wool or slipper sole having its bottom strip or section wider than
the other portions thereof carried upward and provided with a marginal draw
string, the said string serving to shape the sole and likewise serving as a reinforce-
ment therefor at the point where the upper is to be attached, as and for the purpose
specified.
4. A lamb's wool or slipper sole comprising an upper strip of. soft material, a
stiffening strip secured to the upper strip, and a fastening strip of leather or a like
material cemented to the stiffening strip, the finishing or bottom strip being wider
than the other strips and provided with a draw string at its margin, whereby the
finishing strip of the sole may be drawn upward at its margin, concealing the
corresponding margins of the other strips forming the sole, and whereby also said
margin is reinforced and need not be attached to the remaining portion of the sole,
but presents a suitable surface for the attachment. of. the upper, as. and for the
purpose specified.
5. In a slipper sole, a cord or a stitching of cord, or: their round equivalent, or
a heavy thread on the inturned margin of the wearing surface of the sole, serving
as a means of attachment to the upper, as and for the purpose specified.
6. A slipper sole provided with an upturned margin, and an anchorage located
upon the said margin, to which the upper is to be attached, as and for the purpose
specified.
7. In a slipper sole, a draw string located on the inside of the under side of the
margin of the leather or wearing surface of the sole, and a cord or stitching of
heavy thread or its equivalent, located on the outside of the said upturned portion
of the sole as a means for attachment to the upper, as and for the purpose set
forth.
8. In a slipper sole, a transverse lacing located at the shank or lower portion

page_text: of the sole, connecting at said portions an upturned flange, holding the said flange
in place and compelling it to follow the necessary contour of the sole, as and for
the purpose specified.
9. In a slipper sole, a marginal upturned portion or flange, a draw string or an
equivalent tension device extending around the said flanged portion of the sole, the
draw string serving to hold the major portion of the upturned portion of the sole in
shape, and a transverse concealed lacing located at the shank or the instep portion
of said sole, as and for the purpose specified.
