Year: 1883

Mongonui Province of Auckland New Zealand for an Invention of "A SELF
ADJUSTING SAW HANDLE"
PROVISIONAL SPECIFICATION left by the said Benjamin Goulton at the
Office of the Commissioners of Patents on the 19th April 1883.
BENJAMIN GOULTON of Kaeo Wangaroa, County of Mangonui, Province of
Auckland New Zealand. "A SELF ADJUSTING SAW HANDLE
"
My Invention relates to improvements in attaching removeable sawhandles to
the blades of crosscut, and other similar saws, and so that workmen can fix or
detach the said handles with great facility.
The metallic portion of the handle I make of thin Iron or steel plate, bent and
formed so as to receive the wood handle proper, and also to clip on each side of
the sawplate in a manner somewhat similar to the handles of crosscut saws as now
used, a portion is also made solid by an intermediate piece of metal plate, secured
between the two sides preferably by rivetting, and a short sliding bolt works
horizontally in a slot, so as to enter into or be withdrawn from the space in which
the end of the saw is fitted.
The end of the saw is provided with a long, and a short slot placed at right
angles to each other, the long slot is made from the toothed edge of the saw
vertically and the short groove or slot from the end of the saw horizontally.
When the end of the saw is inserted in the slit of the handle, a strong stud
which is securely rivetted between the sides of the handle, enters and engages
with the long slot, and when the handle is in the desired position, the short sliding
bolt is forced either by hand or by a spring into the short slot and thus securely
locks the parts together.

the said Benjamin Goulton in the Great Seal Patent Office on the 9th October

BENJAMIN GOULTON of Kaeo Wangaroa, County of Mangonui Province of
Auckland, New Zealand, "A SELF ADJUSTING SAW HANDLE"
My Invention relates to a self adjusting, removeable "buckle" or sawhandle,
suitable for crosscut, Pit, and other similar saws, which is. so constructed, that an
ordinary sawyer can detach and refix the said handles with greater facility than
has hitherto been possible
In order that my invention may be clearly understood, I shall refer to the sheet.
of drawings, the same letters of reference indicating the same parts in all the
figures.
Fig. 1. is a side view, and plan of the "buckle" or handle.
Fig. 2, represents the end of a Crosscut saw, prepared for the buckle.
Fig. 3, represents the buckle partly withdrawn from the saw.
Fig. 4 represents the buckle ready for use.
In carrying out my invention I make the buckle portion of the handle marked A,
of thin metallic plate, preferably iron or steel, bent round and formed at B, to
receive the wood portion of the handle C, and also to clip on to each side of the
sawplate D. An intermediate piece of plate E, is secured between the two sides of
the buckle, preferably by rivets, and a short sliding bolt F, moving horizontally in
a suitable slot G, is arranged to project into the space in which the end of the saw
fits, so that it may engage with a short slot in the saw marked H.-A spiral
Spring I may be arranged to force forward the bolt F, into the slot H, and retain
it in position, but this may be dispensed with if thought desirable. A strong stud
or rivet-drawbar J., is. secured in each side of the buckle, and engages with the
perpendicular slot K, in tlie saw. The end of the saw is shaped as shown in Fig. 2,
having a shoulder L, the short horizontal slot H, and the perpendicular slot K.
When the end of the sawplate is inserted between the sides of the buckle, the
slot K, is passed over the rivet drawbar J, as seen in Fig. 3, the rounded part of.
the saw M, forcing the bolt F back until it comes opposite the slot G, into which it
is forced by the spring I,-When the bolt is in position as described, the shoulder L
abuts against the top of the buckle, thus the parts are firmly held together. To
detach the saw it is only necessary to draw back the bolt by means of the bent side-
plates N, and press down the handle.
Having now described and fully ascertained the nature of my invention and the
manner in which it may be carried into practice, I would observe in conclusion
that what I consider to be novel and original and therefore claim as secured to mė
by the bereinbefore in part recited Letters Patent, is
:
"
First, The method of attaching sawhandles to saws, substantially as hereinbefore
described, and as illustrated.
Second, A self adjusting sawhandle, substantially as hereinbefore described and
illustrated in the annexed sheet of drawings
In Witness whereof, I the said Benjamin Goulton have hereunto set my hand
and seal this Eleventh day of July in the year of our Lord, One thousand Eight
hundred and Eighty three.
