page_text: I, CARL MORITZ SCHUBERT, of Sornzig, near Kügeln, Leipsig, in the Kingdom of
Saxony, Wheelwright, do hereby declare the nature of my said invention and in
what manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
The object of my invention is to construct improved band-saw machinery, in order
to adapt the same to the formation of the felloes of wheels and analogous
operations.
And in order that my said invention may be particularly described and ascertained,
reference is hereby made to the accompanying drawings, in which similar letters of
reference indicate corresponding parts.
Fig. 1 is an end elevation of my invention. Fig. 2 is a longitudinal elevation.
Fig. 3 is a plan view. Fig. 4 is a plan view with the table removed. Fig. 5 is an
end view of the differential driving mechanism, with the framing and fly wheel
removed, and Fig. 6 is a back view of the same, at right angles to Fig. 6.
g is the frame of the machine. w is the driving shaft, which may be driven by chain
gear from the wheel 8, or otherwise.
The shaft to is fitted with two flywheels ss, and drives the mechanism by the bevel
pinion a.
The underside of the table t is fitted with toothed racks at x, into which toothed
pinions c gear, for driving the table at different speeds, according to the nature of the
work. pp is a segmental plate fitted with radial bars pl pi, a straight bar p³, and a
perforated bar p³. The perforated bar 3 rests upon a similarly perforated bar f; the
latter bar being fixed to the frame g and stayed by the diagonal bar d.
i is a pin which is placed in one of the holes in the bar p³, and also in one of the
holes in the bar, the holes being selected to suit the radius of the felloe to
be cut.
vare two pivotted clamps which hold the block h to the frame p. The lower
bar y and the upper bar v, together with the screws shewn in Fig. 1, form one of the
clamps. The bar y passes under the frame p and the bar is pressed down upon the
block 7.

The clamp operates in a similar manner, with the exception of
An ordinary band saw is mounted upon the wheels bb, with the usual adjusting
screws, as shown in Fig. 1.
The block having been fixed in position upon the frame p, and the pin i placed in
position to suit the radius, the feed is then adjusted, and the operation of cutting
proceeds in the ordinary manner, the frame p guiding the block has the table t
causes it to travel forward.
nnn are three levers for changing the gear, by which the feed is altered in speed
as required; the wheels shown in the drawings being those usually adopted when
variable speeds are required. is a grooved pulley for driving by band.
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 :-
In the construction of sawing machinery the combination therewith of the plate p,
the movable clamps and ¹, the perforated radial bar p³, pivotted to the perforated
bar f, for guiding the block to the band saw in a circular direction, substantially as
herein before described and illustrated by the drawings.
