Improvements in Machines for use in the Manufacture of Welted
Boots and Shoes.
I, AMBROSE STEVENS VOSE, of 564 Washington Street, Boston, Massachusetts,
United States of America, Mechanic, do hereby declare the nature of this inven-
tion 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 a machine for trimming the welt of welted boots and
shoes from its upper outer edge down toward and preferably to the line of stitches
that connect the welt to the outer sole, and for rubbing down the said stitches
to impart to the boot or shoe a neater and more finished appearance.
For this purpose, I mount upon a shaft a rubbing-down disc or tool, with which
co-operates a guard for the upper, loose on a sleeve which is adjustable longitu-
dinally on the shaft as hereinafter described, and which is secured in its adjusted
position so as to turn loosely on the said shaft. The shaft has also fast on it a
cutter for trimming down the welt, with which co-operates a guard for the upper,.
so that the welted boot or shoe may be first, trimmed and then rubbed down on
the same machine without loss of time, as hereinafter described.
Figure 1 represents one form of my improved machine.
Figure 2 a longitudinal section drawn to an enlarged scale showing details of
construction.
Figure 3 an elevation drawn to an enlarged scale, of the rubbing-down disc
shown in Figure 1, and
Figure an elevation also drawn to an enlarged scale, of the cutter or trimmer
shown in Figure 1.
A represents one form of supporting frame or head, having bearings a for a
shaft a provided as shown with a fly-wheel a² and a pulley a³.
.
The shaft al is preferably provided at one end with a conical or taper section a
(see Figure 2) from which extends a cylindrical section a provided with screw-
threads a, and from which cylindrical section extends a smaller conical or taper
section a. The conical or taper section a' has mounted upon it a rubbing-down
tool, preferably a disc a provided with a hub a2 having a taper bore and fastened
on the said section by a taper key or pin. The rubbing-down flise a¹0 is made
taper from its hub a¹ toward its periphery and is provided with radial serrations,
grooves or channels a¹3 to subdivide the disc into a series of radial projections:
or rubbing down surfaces a¹5. The disc a10 has co-operating with it a guard disc.
or shield
provided with an annular lip having a bevelled surface b', which
practically forms a continuation of the rubbing-down surfaces or projections al

in the
The sleeve 63 is moved on the shaft-section a³ to adjust the shield or guard to
the rubbing-down disc a¹o, by a nut 68 having a removable piece or key 6 provided
with a finger or projection 610 which extends into an annular groove
sleeve 63, and the said sleeve is locked in its adjusted position by the lock-nut 615.
The key 6 is detachably. secured to the nut be by a screw 616.
The taper section a' of the shaft has fitted on it a rotary cutter or trimme: 620
consisting of a hub 621 provided with a taper bore and having a series of radial
arms 62, the outer surface of which arms taper from the hub 62 to the circum-
ference or end of the said arms, the said arins being separated by openings 62
and having their front side curved and beveled from the front to the back of the
arm to form a beak 624 and a cutting edge 62, while the rear sides 620 of the said
boot-or-shoe-along-and-places-it-into-position-to-be-operated-upon by the tool or
trimmer has co-operating with it a guard or shield 630 which may be separate
from the shaft and may be suitably supported so as to be moved toward and from
the rotary cutter to vary the depth of the cut; and the said guard has suitable
openings 6 for the passage of the chips removed by the rotary cutter.
The rotary
cutter 620 is secured to its shaft-section a' by a screw 60. In operation, the welted
shoe is held by the operator, so that the rotary cutter 620 will trim the welt from
its upper outer edge down to or substantially near the line of stitches which
secure the welt to the outer sole, and, when trimmed, the operator moves the
boot or shoe along and places it into position to be operated upon by the tool or
disc a¹, which rubs down the stitches and imparts to the shoe a neater and more
finished appearance.
The rubbing-down disc a¹, its shield or guard b, and the cutter 620 are capable
of being easily adjusted to take up wear, so that they may run perfectly accurate
and smooth.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what I
claim is:
First. A machine for use in the manufacture of welted boots and shoes, com-
prising a rotatable shaft, a rubbing-down tool or disc mounted thereon for rubbing
the stitches which secure the weit to the outer sole, and a guard for the said
tool or disc, for the purposes above specified.
Second. A machine for use in the manufacture of welted boots and shoes, com-
prising a rotatable shaft, a rotary welt-trimmer fast thereon, a rubbing-down
tool or disc fast on the said shaft, a guard or shield adjustable longitudinally on
the said shaft and co-operating with the said tool or disc, and means to secure
the said guard or shield in its adjusted position, for the purposes above specified.
Third. A machine for use in the manufacture of welted boots and shoes com-
prising a rotatable shaft, a rubbing-down tool fast thereon, a guard co-operating
with the said tool and adjustable on the said shaft, and means to secure the said
guard in its adjusted position, for the purpose above specified.
Fourth. A machine for use in the manufacture of welted boots and shoes, com-
prising a rotatable shaft having a taper section a¹, a cylindrical section a³ having
screw-threads a6, and a taper section a', a rubbing-down disc a 10 fast on the
section a', a sleeve 63 loose on the cylindrical section as and having a guard or
shield 6 loose on it, a nut to engage with the said screw-threads and connected to
the sleeve 63 to effect longitudinal movement thereof without interfering with its
rotary movement, a rotary cutter or trimmer fast on the taper section a', and a
guard co-operating with the said cutter or trimmer, substantially as, and for the
purposes, above specified.
Fifth. A welt cutter or trimmer consisting of a hub having a series of radial

page_text: orms provided with beveled or tapering front faces and with a curved front side
forming the cutting edge 625 and beak 6, substantially as herein before described.
