Improvements in Machines for Slotting and Boring Umbrella and
other Sticks and Articles.
We, JOHN BENJAMIN JESSON, Machinist, of No. 802, Kimber Street, Camden,
New Jersey, JACOB KEEN WEED, Machinist, of Delaware Avenue, Philadelphia,
Pennsylvania, LEONARD ELDER LADD, Salesman, of No. 2144, Mount Vernon
Street, Philadelphia, and DUDLEY PARAN LADD, Salesman, of Bedford, Massa-
chusetts, all in the United States of America, 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 consists of a machine for slotting umbrella and other sticks and
articles, embodying means for forming kerfs on the said articles, also for forming
a recess at one end of the kerf, and gouging the other end thereof; also a gauge
or stop for limiting the upward motion of the carrier of the stick or article, so that
the depth of the slot or kerf is limited, and slots or kerfs in different sticks or
pieces are uniform in their nature.
It also consists in providing the machine with a boring bit or tool, whereby
openings may be formed in the stick or article to receive the fastening rivets
or pins.
The said invention moreover consists of other novel features as will be hereinafter,
fully set forth.
In the accompanying drawings

Figures 2, 3 and 4 represent front views of portions thereof, the parts being in
different positions.

Figures 6, 7 and 8 represent perspective views of detached portions.
Figure 9 represents a longitudinal section of the parts shown in Figure 8 on
the line, Figure 5.
Figure 10 represents a plan view of a detached portion.
Figure 11 represents a section of a hollow stick with an umbrella retainer to be
fitted in the slot or kerf thereof.
Figure 12 represents a front view of a detached portion.
Figure 13 represents a section of a solid stick with the kerf or slot-forming
cutters applied thereto.
Figure 14 shows a completed kerf or slot in the stick, with an umbrella retainer
above the same, and
Figure 15 represents a section of a portion on line y, y Figure 1.
Similar letters of reference indicate corresponding parts in the several figures of
the drawings.
A designates the base of the machine, the same being secured in any suitable
manner to the table B, said base having a depending boss C within which is
guided the stem D of the rising and falling bed E, the latter being provided
with a channelled slide F, which is adapted to receive the stick or handle to be
slotted.
Rising from the bed A, is a standard G to which is fitted the plunger H, the
lower end whereof carries cutters J, K, L.
Mounted on the base, and driven in any suitable manner, is a circular saw M, the
arbor whereof has keyed or otherwise secured to it, a drum N, around which passes
an operating belt.
P designates a gauge which is pivoted at its inner end to the lower portion of the
standard G, and having bearing against it, the spring Q, whereby said gauge is held
in elevated position as shown in Figure 1, it being noticed that said gauge is

page_text: in the path of the side pieces R of the plunger H, so that when said plunger
descends, it lowers the gauge P, and presses the same against the stick on the
slide F.
Rising from the bed A, is a stop S which is so disposed, that when the gauge P
is raised, it abuts against the lip T of said stop S, thus limiting the upward motion
of the bed E.
Secured to the pillow blocks A' is a stop S', the same being located at the side
of the saw for limiting the upward motion of the stick when raised.
Secured to the arbor of the saw M, is a boring tool or bit U, and below the
same is a table V, on which is supported a carriage W, which as will be seen in
Figure 5, is adapted to have motion in the direction to and from the boring bit.
Rising from the table V is a guide X, the same being adapted to enter the slot
formed in the stick, and support said stick during the boring operation.
The carriage W has a slot Y therein, the same extending parallel with the bit U,
and receiving a screw Z, which is connected with the carriage W, so that said
carriage may be guided in its advancing and returning motions.
The operation is as follows:-
The stick is placed upon the slide F, and the treadle of the machine operated,
whereby the stem D is raised, and with it the bed or table E, with the slide F
and the stick thereon, bringing the stick into contact with the rotating saw, thereby
forming a kerf or slot A in said stick, as seen in Figure 7.
As the stick rises it comes in contact with the gauge P, and as the latter abuts
against the lip T, the upward motion of the stick as supported on the slide F, is
limited, whereby it rises to the required extent.
The treadle is now let go, and the table E with the stick thereon descends, so that
the stick clears the saw.
The stick is then removed from the slide F, and fitted on the guide X of the
carriage W, and the latter is advanced whereby an opening is bored transversely
through the stick as shown in Figure 7, so that when the retainer shown in said
Figure 7 is inserted through the slot A2 into the stick, the opening in said retainer
and stick will register and the rivet or pin will be passed through the same for
holding said retainer in position. The guide is provided with a slot a to form a
registry for the opening in the article made by the boring tool or bit.
This is the operation for slotting and boring a hollow stick, but for a solid stick
after the same has been slotted or cut by the saw M, see Figure 13, the slide Fis
advanced in order to bring the slot beneath the cutters J, K, L, so as to gouge
out one corner of the kerf or slot, and pierce the other corner for a retainer of
the form shown in Figure 14. The operating mechanism of the cutters J, K, L,
is as follows :-
At elbow lever B is mounted on a standard rising from the frame of the machine,
and pivoted at its right angle to the plunger H, whereby the latter may be lowered
by the operation of said lever, the return motion being accomplished by a
spring B which is connected with said lever and a suitable part of the frame of
the machine.
The cutter K is connected with a shaft K¹ whose bearings are on the plunger H, said
shaft being attached to a lever C', whereby a partial rotary motion may be
communicated to said cutter K. The cutter P is fitted to the plunger H, so as to
slide vertically therein, the upper portion of the shank of said cutter being recessed
to receive the cam C2 whose shaft is connected with a toggle lever C³, the latter having
its lower limb pivoted to the lever C', it being seen that owing to the toggle, the cam
may be operated in such manner as to raise the cutter P clear of the path of
motion of the cutter K, as the latter describes its circular motion, as will be seen in
Figure 2, it being noticed that the cutters J, L, primarily pierce the stick at or
about the ends of the slot or kerf therein, see Figure 13, the cutter L rising in due
turn, and the cutter K advancing and cutting or gouging out the corner of the slot
or kerf about the opening previously made by the cutter L, the completed slot or
kerf being shown in Figure 14.

page_text: Ine plunger is raised, whereby the lever returns to its normal position,.
and with it the cutters K, L, the cutter J following the motion of the plunger.
In Figure 14 the prong on the right hand of the retainer is to be driven into the
stick at the lower right hand corner of the kerf A², after which said retainer is fully
driven into the kerf the prong at the left hand entering the adjacent recess below
the same.
