Tables and Fences for Band Sawing and Fret Sawing Machines.
I, EDWIN WHIBLEY, of Osmington Villa, Griffin Road, Plumstead, in the County
of Kent, Carpenter, 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 reference to improvements in or relating to the tables of band
sawing and fret sawing machines whereby such machines are rendered capable of
producing work which they have hitherto been unable to perform.
According to my invention the table is mounted upon the frame of the machine in
such a manner that it can be turned about two axes at right angles to each other and
one of which coincides with or is parallel to the cutting edge of the saw, the
arrangement being such that the table can be turned around the saw and be caused
to assume an inclined attitude with relation thereto as desired, means being provided
when necessary, for holding the table in position after it has been adjusted.
The pivot or bearing upon which the table turns in a plane at right angles to
the saw, is slotted to receive the saw. The sides and rear edge of the saw are
supported or guided in a lateral sense by an adjustable guide.
The top of the table may be provided with a removeable fence so constructed and
arranged that it can be adjusted in an angular sense upon the table and can be moved
in the direction of its length and in a direction at right angles or other required
angle thereto these movements being effected simultaneously or separately as desired.
In the accompanying sheet of illustrative drawings-
Fig. 1 is a side elevation of so much of a band sawing machine as is necessary
to illustrate the application thereto of a table constructed according to my Invention.
Fig. 2 illustrates partly in vertical section, and partly in elevation, the table
and the bearings for supporting the same; it also shows in elevation the adjustable
saw guide.
Fig. 3 is a plan of the bearings and saw guide with the table removed.
Fig. 4 is a plan; and
Fig. 5 a transverse section of part of the table across which extend grooves or
recesses in the lower of which is fitted an adjustable plate or bar that is provided with
a stop piece and means for securing it in position.
Fig. 6 is a plan of fences with means for adjusting them in position and for attaching
them to each other and to the table.
Figs. 7, 8 and 9 are transverse sections upon the lines ; y y; and z z respectively
of Fig. 6.
Fig. 1 is drawn to a smaller scale than the other figures.
1 is an endless band saw, passing around pulleys 2 carried by the frame 3 of the
machine. 4 is the table formed with a slot 5 through which the band saw passes.
To its underside is secured two segmental plates 6 that take into curved segmental

page_text: bearings 7. These bearings are carried by and project upward from a hollow cap,
cover, or socket 8 (hereinafter called a cap) with which they may advantageously
form one piece.
To the bearings 7, which serve when necessary to support the
table in a horizontal position as shown in Fig. 2, are secured bolts which project
through curved slots 8 in the segmental plates 6 and are provided with nuts for
clamping the plates and attached table in a horizontal position, or in an inclined
position. The cap 8 is mounted to rotate upon a pivot or bearing 9, which may
be in the form of a truncated cone as shown, or be of other suitable form such as
a cylindrical pivot. The cap is held to the bearing by an annular plate 10 which
is secured to such cap and takes beneath a flange 11 on the conical bearing 9 as
shown. 12 is a vertical slot formed in the cap and conical bearing as shown more
clearly in Fig. 3; it corresponds with the slot 5 in the table. In the pivot or
bearing 9 there may be provided four equi-distant holes, into one or other of which
a pin, carried by the cap, may be caused to enter for the purpose of holding the
table in one or other of four positions which are ninety degrees apart.
13, 13 are bolts with nuts by means of which the annular plate. 10 may be secured
to the underside of the cap in such a manner that the flange 11 is held between
them. By loosening the nuts the cap may be adjusted into any intermediate
position between those provided for by the pin on the cap and the holes in the
bearing just referred to; the cap being afterwards secured in position by tightening
up the nuts.
With the construction described, the table can be inclined at various
angles to the cutting edge of the saw, as indicated by dotted lines in Fig. 2, and
it can be rotated around the saw according to the kind of work to be done.
14 is a guide which embraces the back and part of the sides of the saw. In the
example shown it is carried by a screw rod 15 that extends through the bearing 9
into the slot 12, and is adjusted in position to suit saws of different widths, by a hand
nut 16, endwise movement of which, is prevented by stops 17 between which it is
placed. The guide may however be arranged and adjusted in various ways without
departing from the nature of my invention. 18 is a fence adjustably mounted upon a
plate 19 to which it may be secured by clamping plates 20. The plate 19 is formed
with a slot 21 through which extends a screw bolt 22 that adjustably connects the
plate to a bar 23. This bar, which may be of dove tail shape in cross section as
shown, and is formed with grooves 24 and an intervening projection 25 on its under-
side, is arranged to slide in a dove tail or other suitably shaped recess 26 in the top of
the table and over another bar 27. Means such as bolts 23*, the heads of which are
flush with the surface of the table and bear against one side of the bar 23, may be
employed for holding such bar in position when necessary, the shanks of the bolts
extending to the underside of the table, where they are provided with nuts.
The bar 27 is arranged to be adjusted endwise in another recess 29 in which it may
be clamped by any convenient means, such as a bolt head 30 that rests upon a fillet 31
on the bar, the shank of the bolt extending to the underside of the table where
it is provided with a nut by which the clamping or releasing of the bar may be
effected. Or the bar 27 may be formed with a slot extending throughout the greater
part of its length and the edges of which are formed with a fillet upon which the
head of the tightening bolt rests. The bar 27 is provided with a stop piece 32 that
extends into one or other of the grooves 24 in the bar 23 when this bar is placed in
the recess 26, and serves to limit end wise movement of the latter bar in one direction
by contact with the projection 25 thereon. By the construction described, the fence 18
may be adjusted and secured in any position relatively to the bar 23; it may also be
adjusted in the direction of its length and be then clamped in its adjusted position,
and it may also be traversed across the table by causing the bar 23 to slide in the
recess 26, the adjustment and direction of motion depending upon the work to he
done. By this means the material to be sawn may be guided and readily moved over
the table to the saw to cut circular, elliptical and irregular forms of various kinds.
33 is an auxiliary fence secured to the main fence 18. It is provided with an adjust-
able stop 34 for the purpose of adapting the machine for dovetailing or other kinds
of work.

page_text: It will be obvious that by means of a table that can be inclined to the saw and be
rotated about the cutting edge thereof, and a fence that can be moved both in the
direction of its length and in a direction at right angles or other required angle
thereto a sawing machine of the kind mentioned is adapted in addition to the
capabilities of ordinary band and fret sawing machines, to cut articles of a great
variety of forms such as oblique prisms, cylinders, or other forms of similar and
equal parallel section. It is also adapted to cut material in the form of hand rail
wreaths for stairways and the various bevel and other cuts necessary for roof timber
and other irregular and curved work. Also by arranging the fence 18 so that it can
be adjusted and fixed in an angular position with reference to the plane of the saw,
and by the use of the adjustable fence 33 and stop 34 a series of cuts may be made
in the material operated upon, the cuts of each pair being at an angle to each other so
that when the intervening piece of material is removed a dovetail or pin, as the case
may be, will be left.
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 a band sawing or fret sawing machine, a work table capable of turning about
two axes at right angles to one another, one of which coincides with or is parallel to
the cutting edge of the saw.
2. In a band sawing or fret sawing machine having a table of the kind referred to
in the preceding claim, an adjustable saw guide located below the table substantially
as described.
3. In a band sawing or fret sawing machine, a table provided with a guide fence
mounted on such table, and capable of being adjusted in an angular sense upon the
same, and of being moved both in the direction of its length and in a direction
inclined thereto substantially as described.
4. Providing the table of a band sawing or fret sawing machine with a fence con-
structed arranged and operating substantially as herein described with reference to
Figs. 6 to 8 inclusive whether the auxiliary fence 33 and adjustable stop 34 be used
or not.
5. My improved table for band sawing or fret sawing machines constructed and
operating substantially as herein described with reference to Figs. 1, 2, and 3 of
the drawings annexed, whether or not it be used in conjunction with an adjustable
saw guide such as 14 and with the improved adjustable fence 18 or with either.
Dated this 31st day of January 1889.
