PROVISIONAL SPECIFICATION.
Improved Self-acting Feed for Sawing Machinery.
1, SAMUEL BASTOW, of New Dock Saw Mills, Chadwick Street, Leeds, Timber
Merchant, do hereby declare the nature of this Invention to be as follows:-
The object of my invention is to construct an improved self-acting feed for
sawing machinery, which may be used either for ordinary ripping, or deep cutting, to
self centre, one side forming a fast fence if desired, to bevel cut at any angle, or to
feed a number of boards through at one time.
I employ an horizontal shaft upon which is pivotted a bed and within the two sides of
the bed upon the shaft is a worm, upon the bed at each end are bearings carrying another
shaft parallel with the bed, also resting upon the bed are two vertical frames sliding
on the same with adjustable liners, each carrying two geared rollers. The parallel
shaft passes through the vertical frames. The geared rollers are driven by bevel wheels
sliding on the parallel shaft and connected with the vertical frames. The parallel
shaft is provided with right and left hand threads for regulating and obtaining pressure
upon the rollers by means of spiral springs, but weights can be used in preference if
desired.
Motion is given to the parallel shaft by means of a worm wheel gearing into the
worm upon the horizontal shaft, which is again driven by a spur wheel gearing into
a spur pinion. The bearings of the horizontal shaft are carried in suitable castings
each being provided with a quadrant slot. At right angles to the geared rollers are
a table or
suitable adjustable guide rollers which act when required either as
fence.
For ordinary ripping or deep cutting the geared rollers are in a vertical position;
for cutting bevels, the pivotted bed is turned downward upon its pivot to the angle
required, the worin wheel turning upon its worm, and the spur wheel upon its spur
pinion, and to put the rollers in proper position, after being canted the horizontal
shaft is moved a corresponding distance up the quadrant slots.
For feeding a number of boards through at one time, the bed is turned down
until the geared rollers are in an horizontal position, then the horizontal shaft is
moved up to the top of the quadrant slots, so as to bring the geared rollers back to
their original relative position with the saw.
The vertical frames can be slightly canted forward by means of the adjustable
liners, so as to give a lead to the rollers against the fence, when working in an
horizontal position.

COMPLETE SPECIFICATION.
Improved Self-acting Feed for Sawing Machinery.
I, SAMUEL BASTOW, of New Dock Saw Mills, Chadwick Street, Leeds, in the
O County of York, Timber Merchant, 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:-
The object of my invention is to construct an improved self-acting feed for sawing
machinery, which may be used either for ordinary ripping or deep cutting, to self
centre, one side forming a fast fence if desired, to bevel cut at any angle, or to feed a
number of boards through at one time,

page_text: DESCRIPTION OF DRAWINGS.
Fig. 1, is an end elevation of my improved feed for sawing machinery. Fig. 2, is
a side elevation of Fig. 1. Fig. 3, is a detail showing means of securing and
releasing the bearings of the guide rollers to and from the feed rollers.
A is a horizontal shaft upon which is pivotted a bed B, and within the two sides
of the bed B upon the shaft A, is a worm or cross geared wheel D, gearing into the
worm wheel or cross geared wheel D', upon the bed B at each end, are bearings E
carrying another shaft F, parallel with the bed B, also resting upon the shaft F,
supported by bed B, are two vertical frames or standards G, carrying four geared
feed rollers H¹; the vertical frames have adjustable liners or set screws H; by screw-
ing up one or other of the set screws H against the shafts Y, they adjust or cant
forwards the frames or standards, sc as to give a lead to the feed rollers against the
fence when working in a horizontal position.
The geared feed rollers H¹, are driven by bevel wheels H³ and H³, sliding on
the parallel shaft F, W is the pedestal casting, for supporting the apparatus, and
to which the quadrants ✗ are bolted.
The parallel shaft F passes through the vertical frames G, which have each a
projection or boss J, in which is an annular recess K, a nut L overlaps the boss J,
and is secured thereto by a pin or set screw M.
For
The parallel shaft F is provided with right and left hand threads N, corresponding
to the threads in the nuts L, for moving the vertical frames nearer to or further
from each other, according to the size of the wood being fed to the saw.
regulating the pressure upon the rollers, spiral springs O are employed, preferably
to act upon the bearings P of the rollers.
Motion is given to the parallel shaft by means of a worm D, gearing into the
worm wheel D¹, or cross geared wheels D and D¹ are preferably used upon the
horizontal and parallel shafts, which may be driven by sprocket wheels and
chain Z.
The bearings of shaft A, are carried by two quadrant slots ✗, which are bolted
to pedestals W.
At right angles to the geared rollers are suitable adjustable guide rollers S, which
act when required either as a table or fence.
For ordinary ripping or deep cutting, the geared rollers are in a vertical position ;
for cutting bevels the pivotted bed with vertical frames and geared rollers on, is
pulled back, so that the rollers clear the saw, and then is turned downwards upon
the pivotted shaft. A to the angle required; the cross geared wheels D and D¹
turning upon each other, and the sprocket chain accomodating itself to this arrange-
ment, and to put the rollers in proper position, after being canted the horizontal
shaft is moved a corresponding distance up the quadrant slots.
For feeding a number of boards through at one time, the bed B is turned down
until the geared feed rollers H' are in a horizontal position, then the horizontal shaft A
is moved up to the top of the quadrant slots X so as to bring the geared feed
rollers H back to their original relative position with the saw.
Having now particularly described and ascertained the nature of this invention and
in what manner the same is to be performed, I would have it understood that the
details of construction may be varied without departing from the principle of my
invention; what I claim is :-
1. An improved feed which can be used for the various purposes such as shown
and described.
2. The canting of the feed rollers so as to cut at any angle from vertical to
horizontal such as shown and described.
3. The arrangement whereby the feed rollers can have any lead required given them

page_text: towards the fence when they are in the horizontal position, such as shown and
described.
4. The guide rollers S constructed so as to act either as a table or fence such as
shown and described.
