spindle which carries the cutting tool is made square, at its upper end, and.

page_text: moves through and is guided by a square passage in the upper part of the
framing. The lower part of the spindle is by preference cylindrical, and works
through and is guided by a cylindrical passage, which is capable of being
adjusted in its position. The spindle is made with a rectangular slotted frame
intermediate of its length, in which there is a slide which receives the crank
pin of an excentric or crank; on the axis of the excentric or crank is a toothed
wheel which gears with and is actuated by another toothed wheel, on the axis
of which is a lever handle, which is weighted at its back end. The frame
carrying the crank axis and the axis of the lever may be made to admit of
adjustment in its position.

and ascertain the nature of the said Invention, and in what manner the same
i

page_text: was to be performed, and cause the same to be filed in the Great Seal
Patent Office within six calendar months next. and immediately after the
date of the said Letters Patent.
.
NOW KNOW YE, that I, the said Samuel Lumb, on-behalf of myself, and
the said Henry Gallon, and Joseph Henry Bean, do hereby declare the nature
of the said Invention, and in what manner the same is to be performed,.to
be particularly described and ascertained in and by the following statement
thereof, that is to say :-
This Invention has for its object improvements in machinery for slotting,
morticeing, tennoning, and cutting wood, iron, and other substances, and
consists in the application of a crank or excentric to such machines in order
to actuate the cutting tool, such crank or excentric acting with a slide
arranged to move in a slot formed in the spindle which carries the cutting
tool. The spindle which carries the cutting tool is mounted on a standard,
so as to be capable of sliding up and down in a vertical direction through
guides connected with the upper part of the framing. The spindle is by
preference cylindrical, and the guides through which it works are so con-
structed as to be capable of being adjusted in their positions, either up or
down the standard. The excentric or crank is actuated by means of a hand
lever, and both these parts are carried by a frame which is made to admit of
adjustment in position together with the guides.
And in order that our said may be most fully understood and readily carried.
into effect, we will proceed to describe the Drawing hereunto annexed.
DESCRIPTION OF THE DRAWING.
Figure 1 is a side view, and Figure 2 is a front view of a machine con-
structed according to our Invention. a, a, is the bed of the machine, which is
bolted to and carried' by the two upright frames b, b; c is a standard fixed to
the bed a; on it are mounted the frame d and the two slides e and e¹, which
are all connected together by a plate f, so that they may be traversed at the
same time along the standard c in a vertical direction by the screw at the top
of the machine; the frame. d carries the axis g of the crank or excentric h,
and the upper and lower slides e and e¹ serve as guides for the spindle i of.
the cutting tool; this spindle is cylindrical, and passes through the rectangular
piece or block j, and is fitted with two collars, which enclose the piece j
between them; thus the spindle works up and down with this block as if it:
were one piece with it, but at the same time the spindle can be made to
rotate independently of the said piece or block. At. the extremity of the

page_text: spindle a socket is formed to receive the chisel or cutting tool, which be
may
similar to tools employed in slotting, morticeing, and tennoning machines
heretofore employed. The up-and-down motion is given to the tool by the
handle, mounted on the axis g'of the crank or excentric , before mentioned.
h is a pin on the crank or excentric entering a slide e, which is capable of
traversing in the slot or opening in the frame j', which is attached by screws to
the back of the piece or block j, thus, as the handle k is worked up and down;
a similar motion is communicated to the crank pin h¹, and by it a rectilinear
motion is given to the spindle and tool. The spindle is arranged so that it
may be free to revolve, in order that the position of the tool may be changed
when required to cut in the opposite direction to that for which it was
previously set; this is done by means of a ring m, through which the lower
part of the spindle works; it has a screw m¹ passing through it, and the end
of the screw enters a groove cut from end to end of the lower part of the
spindle, thus the ring m does not interfere with the up-and-down motions of
the spindle, and when it is turned round by means of its handle m², it carries
the spindle with it; the ring m has two notches cut in it opposite each other,
and into one or other of these the spring catch n, carried by the slide e¹, drops
when the tool is in the proper position to cut either in one or other direction.
The bed a of the machine has guides formed on it, along which the slide o is
capable of being traversed by turning the hand wheel p and the screw formed
on its axis; the slide o carries a second slide q, arranged to traverse in
guides placed in a direction at right angles to the guides on the bed a; q¹ is a
rack formed on the slide q, and motion is given to the slide by a pinion
gearing with the rack, and mounted on an axis which is carried in bearings
on the slide o; the hand wheel r is fixed at the end of the pinion axis, and by
turning it the slide is moved along in its guides. The article to be brought
under the tool is placed on the slide q, and is clamped between the vertical
plate 2 of the slide and the end of the screw s, then by turning the hand
wheels p. and r, any point in the article may be brought under the tool.
The machine above described is more particularly adapted for cutting wood,
but it may also be employed when fitted with suitable cutting tools for
shaping iron and other materials.
Figure 3 shows a frame of saws which may be fitted to the end of the
spindle of the machine for cutting tennons; these saws when in use pass
through holes or passages formed for them in the slides o and q, these
passages are of sufficient size to enable the slides to traverse a short distance,
by preference about eight inches, without coming in contact with the saws.

page_text: The stems at the bottom of the saw frame enter suitable guides formed for
them on the framing. The same saws may also be employed for ripping
as well as for cutting tennons, and then it is convenient to remove the slide q.
In witness whereof, I, the said Samuel Lumb, have hereunto set my
hand and seal, this Eighteenth day of July, in the year of our Lord
One thousand eight hundred and fifty-nine.
