MACHINE FOR SLOTTING UMBRELLA-STICKS.

SPECIFICATION forming part of Letters Patent No. 410,975, dated September 10, 1889.

- Application filed February 27, 1889. Serial No. 301,304:- (No model.)

To all whom, it may concern:

Be it known that we, JOHN B. J ESSON, a citizen of the United States, residingin the city and county of Camden, and State of New Jersey, and JACOB K. WEED, a citizen of the United States, residing in the city and county of Philadelphia, and State of Pennsylvania, have invented a new andusefullmprovement in Machines for Slottin g Umbrella-Sticks, dac.,

ro which improvement is fully set forth in the following specification and accompanying drawings.

Our invention consists of a machine for slotting umbrella and other sticks and articles, the same embodying means for forming a kerf in said article, and also for forming a `recess at one end of the kerf and gouging the other end thereof.

The description of the invention will herezo inaft'er be limited to the slotting of umbrellasticks, in order to receive the retainer for the runner of the umbrella, a form of said retainer being shown in the drawings accompanying this specification.

Figure 1 represents a front elevation of a machine for slotting umbrella-sticks embodying our invention. Figs. 2, 3, and t represent partial front views and partial vertical sections of detached portions thereof. Fig.

3o 5 represents a vertical section of a portion on line oc oc, Fig. 1. Fig. 6 represents aside elevation of the parts shown in Fig. l. Figs. 7 and 8 representperspective views of detached parts. Figs. 9 and 10 illustrate the Vwork of the machine. ,Fig 11 represents a side elevation of a retainer to be applied to the stick shown in Fig. 10. y

Similar letters and numerals of reference indicate corresponding parts in the several figures.

Referring to the drawings, A designates the base of the machine, which is secured in any suitable manner to a table, bench, dac.; B, said base having a depending boss C, in which is guided the stem D of arising and falling bed or table E, the latter being provided with a channeled slide F, which is adapted to travel in the direction of the length of the machine, as indicated by the straight arrow in Fig. l,

and receive the stick or handle F to' be 5o slotted. The slide F carries a clamping device Ffi, which prevents the stick or handle F from moving after the latter has been placed in position, said slide also being provided with a stop F3, which abuts against a shoulder F4 55 on the table E when said slide F has traveled the desired distance, and prevents farther advance of the same, and is furthermore provided with a mark or indicator l to enable the operator to place the handle or stick F 6o in the proper place.

Rising from the base A is a standard G, the upper portion of which is provided with a vertical recess H and cap J, forming a guide, through which freely passes the plunger K, carrying cutters L M N and mechanism for operating the same, as will be hereinafter described.

Mounted on the base A and driven in any suitable manner is a circular saw O, and ris- 7o ing from said base is a horizontal stop P, against which the stick or handle F strikes when the bed or table E has been elevated to the desired extent and limits the ascent of the same. The bed or table E is provided with abutments or stops R, which strip the stick or handle F from the cutters when the latter are raised.

S designates a rod, the lower end of which is pivoted to a treadle T and the upper end 8o to a lever U, the latter being mounted on a hanger V, secured to a collar WV on the boss O, the end of the lever U opposite to that connected with the rod 'S being in contact with the roller X, mounted on the stem D of the bed or table E.

Y designates an elbow lever, which is mounted on a standard Y', rising from the frame of the machine, said lever being pivoted at its angle or bend to the plunger K, 9o whereby the latter may be lowered by the operation of said lever, its return mot-ion being accomplished by a spring Y2, which is connected to the end of the lever and a suitable part of the frame of the machine.

' The cutter M is connected with al shaft M', whose bearings are on the plunger K, said shaft having connected with it a lever Z,

whereby a partial rotary motion will be communicated to said cutter M. The cutter N is itted to the plunger K, so as to slide vertically therein, the upper portion oi the shank of said cutter being recessed to receive the cam A', whose shaft A2 is connected with a toggle U', the latter having its lower end pivoted to the lever Z, it being seen that owing to the toggle C the cam A may be operated in such manner as to raise the cutter N clear of the path of motion ot the cutter M as the latter describes its circular motion, as will be seen in Fig. 2.

The operation is as follows: The stick is placed on the slide F, and so located that a mark--such as 2--previously made on said stick willregister with the mark l on said slide. The handle ot the clamp F2 is then closed, thus bringing the nose 3 thereof against the stick and holding the same in position. (See Figs. l and (i.) The t-readle Tis now depressed, thus raising the stem D and consequently the bedor table E, and bringing the stick in contact with the rotating saw O, (see Fig. 4,) thereby cutting the kerf F5 in the stick the required depth. When this has been accomplished, the stick comes in contact with the stop P, and is thereby prevented from further ascent. The treadle 'l is now released and the bed E descends to its normal position, after which the slide F, which carries the stick, is moved by hand in the direction of the straight arrow. (See Fig. l.) )Vhcn the kerf F5 has reached a point directly under the cutters L M N, the stop F3 comes in contact with the shoulder F and prevents further advance of the slide F. The lever Yis now moved in the direction of the arrow, (see Fig. 6,) and causes the plunger K to descend, thus forcing the cutters L M N into the korf previously cut. (See Fig. 3.) rlhe cutters L and N pierce the stick at the ends of the kerf F". (See Fig. 9.) The handle of the clamping device F2 is now released and the lever Z moved in the direction of the curved arrow, (see Fig. 1,) whereby the cutter M is caused to advance in a curvilinear direction and cuts away or gouges out the corner of the kerf F5 adjacent to the opening made by the cutter N. Simultaneously with or slightly in advance ot this operation the cutter N is moved from the path of the cutter M, this being accomplished by the operation of the link. l', crank C2, and cam A through the medium of the lever Z, whereby the shank of the cutter N is raised, and the cutter accordingly clears the cutter M as the latter advances. The plunger is now raised and the lever Z returned, whereby the cutters M N resume their normal position. The stick,being stripped of the cutters, is then re moved and the slide run back, so that the op erations may be repeated.

Secured to the plunger K is a stop D', which limits the downward motion of said plunger, thus preventing the cutters L M N trom en tering too far into the stick.

Referring to Figs. 3 and 4, the slide F has a bolt E depending therefrom, and the table E and base A arc provided with. slots G G2, respectively. One end of the slot of the base is enlarged, so as to allow the head of the bolt E to freely pass through the same and enable the bed or table E to be raised. Vhen said bed or table E is lowered, the slot G of the base allows the bolt E to move in a longitudinal direction with the slide, but pre vents the latter from rising, excepting when the head of; said bolt again registers with the enlarged portion of said slot of the base.

rFhe lever Z has a spring Z connected with it for restoring it to its normal position.

After the work is performed, the retainer may be fitted in position, the longitudinallyextending spur being driven into the wood at the gouged-out corner of the kort, and the spur at the opposite end entering the openin formed by the cutter L.

Figs. 7, S, l), and l0 are drawn on a scale larger thanv those in the other figures.
