page_text: I, JOHN CHARLES of Gloster Terrace, Weymouth, in the County of Dorset, Builder,
do hereby declare the nature of this invention and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement :-
This invention has for object to render fret work machines capable of being worked
with greater ease and with less noise than those at present constructed so as to adapt
them more especially for the use of ladies, children, invalids and inmates of hospitals
and other large buildings.
A fret work machine constructed in accordance with this invention is shown in the
accompanying drawing Fig 1 being a side view, Fig 2 an end view, Fig 3 a plan of
the work table or bench and Fig 4 a top view of the slide bracket g.
a is a removable square bar-preferably of steel-held in socket b and metal plate c
which latter also serves as a stop for the work on the table or bench. To the free end
of the bar a is screwed or otherwise fixed a round bar d the outer end of which
reaches up to or a little beyond and over the position of the working fret saw blade
and so that the two bars together form a kind of overhanging spring bar. This bar
may if, preferred, be made in one piece of any suitable cross section or of more than
one cross sectional form. c is a flexible or elastic band with clip which couples the
end of the spring bar to the saw frame. 7 is a bracket sliding up and down over
fixed vertical guide rods the upper ends of which are held in the under side of the
table and the lower ends stepped into part i. This bracket g may also be made in two
parts, fixed together as shewn in Fig 5, the horizontal plate taking on to the
vertical bosses and web. The saw handle may be turned freely in the horizontal part
of slide bracket g so as to move the saw and saw frame along the arc of a circle.
k are india rubber or other elastic rings serving as noiseless stops to slide bracket g on
its down stroke and is an elastic ring of similar material fixed on the saw frame
and serving as a noiseless stop to slide bracket 9 on its up stroke. m is a tool drawer.
n is a slot in bracket g, for the withdrawal of the saw without any unfastening.
Instead of the flexible or clastic band e as shewu, a metallic or other spring may be
employed for coupling the overhanging bar to the saw frame.

page_text: The purpose of the overhanging bar and elastic or spring coupling is, when the fret
saw is being worked, to relieve the hand, more or less as desired, from the weight of
the saw and working parts in connection therewith, assist the working of the same,
and in conjunction with the slide mechanism keep the saw in the proper working
position, this mechanism having for object to insure an undeviating reciprocal
motion.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed; I declare that what I
claim, is:
1. In fret work machines operated by hand the combination of an overhanging bar
and elastic or metallic spring coupling for the purpose specified substantially as
described and shewn.
2. The slide bracket 9 in combination with fixed guide rods or their equivalent,
for the purpose specified substantially as described and shewn.
3. The elastic stops k, l, in combination with slide bracket g and guide rods / for
the purpose specified substantially as described and shewn.
