3. TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HOWARD
PRATT GARLAND, of San Francisco, in the County of San Francisco,
and State of California, one of the United States of America, Engineer,
send greeting.
WHERAS I am in possession of an Invention for “IMPROVEMENTS ON
SEWING MACHINES FOR STITCHING SACKS, BAGS, CARPETS, AND FOR OTHER LIKE
PURPOSES," and have petitioned Her Majesty to grant unto me, my
executors, administrators, and assigns, Her Royal Letters Patent

NOW KNOW YE, that I, the said Howard Pratt Garland, do hereby
declare that the following Complete Specification, under my hand and
seal, fully describes and ascertains the nature of the said Invention,
and the manner in which the same is to be performed, in and by the
following statement :—
My Invention is intended as an improvement upon the machines for
sewing bags, &c., for which Letters Patent have been heretofore granted
to me, consisting of a mechanism for actuating a spiral needle carrying
a thread, to unite the edges of the cloth or material presented to the
needle.
My present Invention relates to a new and improved means for
preventing the spiral needle from being drawn forward or from creeping
or crawling as the spirals make progress through the cloth, in which
case the spirals becoming contracted the cloth is liable to be caught and
rolled or gathered between them, and the progress of the sewing is
retarded unless considerable care is taken to guide and feed the cloth to
the needle.
It consists mainly of a slotted mandrel secured to a slotted strap that
is fastened to one side of the table of the machine by a set screw. The
mandrel has an enlarged head, and the last spiral of the needle passes
around it and is bent inward and made smaller in diameter to fit against
the shoulder of the enlarged head and hold the needle from moving
forward beyond the position where the last spiral comes in contact with
the shoulder.
A smooth open mouthed slot is made in the mandrel from one end to
the other, so that the edges of the sack or cloth being sewed will easily
pass out as they leave the heel of the needle when guided by the fingers
of the operator.
Referring to the Drawing for a better description of my Invention,
A represents the mandrel provided with an enlarged head B and open
mouthed slot C. The head B forms a shoulder D for the end of the last
spiral to turn against the point E' of the needle E, being depressed or bent
inward so that the spiral needle is prevented from being drawn forward
out of position or its spirals contracted, which would be liable to happen
in case the heel or last spirals of the needle were not controlled in a
similar manner to that herein described and shown,

page_text: The end of the slot O at the head of the mandrel is made somewhat
deeper than the other portion, and with a flaring mouth, in order to
guide the edges of the cloth or material being sewed, and allow them to
pass smoothly through the slot and out at the end of the mandrel.
The mandrel A is secured to the end of a slotted strap G, by means of
which it is fastened and held in place in the machine, a slot being made
in the end of the strap, and a set screw being employed to hold it in
position. By this means the position of the needle can be regulated and
the pull or tension upon it can be adjusted at will.
The cloth is fed to the needle in the usual way, as described in my
former Letters Patent, being guided by the operator so that the edges of
the bag or fabric will enter and pass through the slot in the mandrel as
they leave the needle.
It will be evident that a threaded screw secured to the end of the
mandrel A might be substituted for the slotted strap to be held by
passing through the side of the machine and being secured by means of
a nut on the outside, so that the position of the needle could be adjusted
as before described, but I prefer the slotted strap for the reason that it
possesses more elasticity and will vibrate with the vibration or recoil of
) the needle.
Having thus fully described the nature of my said Invention, and in
what manner the same is to be performed, what I claim. as new and
desire to secure by Royal Letters Patent is,-
First. The mandrel A provided with the enlarged head B, slot O, and
3 slotted strap G, as and for the purpose specified, constructed substan-
tially as set forth.
Second. The combination with the mandrel A, provided with an
enlarged head and slotted strap, of the spiral needle E, having the
point of its last spiral bent in, substantially as and for the purpose.
> specified.
In witness whereof, I, the said Howard Pratt Garland, have
hereunto set my hand and seal, this Third day of May, A:D.
