Specification of Letters Patent.

Application led April 1, 1912. Serial No. 687,686.

To all 'whom 'it may conce/m Be it known that I, Geenen A. TURNER, a citizen of the lUnited States, residing at Kane, in the county oli McKean and State of Pennsylvania, have invented certain new and useful lmlnovements in lVoodwoi-king- Machines; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to 4which it appertains to make and use the same.

My invention relates to machines for reaching brush handle blanks, the object being to provide means whereby the entire operation of setting, clamping, cut-ting and releasing the blanks will be automatic, and it consists in means for automatically moving the blanks into position against a solid support moving toward the cutters, means for clamping them against said supports, cutters 'for reaching or reducing the thickness of the shank and part of the head of l the handle and means for releasing the blanks.

My invention further consists in the parts and combinations of parts and in the details of construction as will be more fully explained and pointed out in the claims.

In the accompanying drawings, Figure 1 is a View in plan of the improvement; Fig. 1EL is a View of the blank before it has been operated upon, and Fig. 1b is a view showing the blank after it has passed through the machine; Fig. 2 is a plan view of the revolving table with some of the parts removed, showing the fixed table and some other parts in dotted lines. Fig. 3 is a section on line y-y of Fig. 1; Fig. 4 is a view on the line .Q2-m of Fig. 2; Fig. 5 a view in detail showing the means for holding the table` against any vibration While the blank is being acted upon; Fig. 6 is a view of the mechanism for shifting the blank to position to be clamped; Fig. 7 is a view of the mechanism for antomatically dislodging the blanks after they have been operated upon; Figs. S and 9 are viewsin perspective of parts of the clamping mechanism.

1 represents a circular cured to the upper end of a vertical shaft 2, which has bearings in the supportlng frame 3. This shaft is provided near 1ts lower end with the worm Wheel 4, lmeshing with the worm 5, on shaft 6, the latter being driven by a motor, or by any other suitable table, centrally semeans. 'lhe table is fiat on top, and is provided with a series of radially disposed oblong openings 7, the shape ot' which is clearly shown in Figs. 1 and 2. These openings are preferably spaced equal distances apart, and each has two straight parallel sides 8, extending from a point adjacent the hub or center of the table, outwardly toward its periphery, and two straight outwardly divergent sides 8 and S" which are continuations ot the sides S, the sides 8", each being cut away at its outer end to receive one end of the head 9 of the handle blank 9. This cut away portion of the side wall Sl of the openings7 conforms to the angle of one end 9 of the head of' handle blank 9, and sup orts the latter in the movement ot' the blan toward thecutters, the handle or stem 9b of the blank being supported against the straight wall 8b, as clearly shown to the left of the center in Fig. 1.

Secured within recessed seats 10 at the outer ends of the openings 7, are the clamping blocks 11, which latter are secured in place by any suitable means, and which have roughened or toothed faces to engage the head end of the' blank as clearly shown in Fig. 3.

Adjustably secured to frame 3, and located under the rotating table 1, is the fixed4 table 12 which latter is arc-shaped as shown, and extends less than halt1 way around the rotating table. Thisl table is located immediately under the openings 7, and well up to the rotating table l, and forms a bottom or closure for a series of openings 7 just in advance of the rotating cutting tools 13.

Mounted at the inner ends of openings 7 and between the parallel sides 8 thereof are the

clamping members

14 and 15, shown detached in Figs. 8 and 9. These members rest on the flanges 1G integral with table 1, and are held in place by the removable plates 17, secured to the top of the table, and overlapping the guide flanges of said clamping members. Clamping member 14 is simply a block with two guide flanges 14, and is provided at its inner end with an adjustment screw 14, which may be locked against movement by set screw 14. Clamping member 15 is similarly shaped in cross section and is provided at its outer end with a clamping jaw 15 and on top with a pin 15 against which the spring 16 bears and tends to push clampmg member 15 inwardly Patented July 8, 1913.

toward clamping member 14, the -two mem bers being ranged in pairs, one pair for each shaft 20,

and o-n opposite sides of thecam, and hold the shafts vertically and also laterally. Each shaft is provided at its upper" handle 20a, and at its lower end with al dou-- of lever 20b ble armed leverV 201, one arm of which is adapted to engage the stop 23 and turn shaft 20 in a direction -to force `its cam 19 against the head of screw 14", and thus force both clamping

members

14 and 15 toward the blank 9, for clamping the latter in its propel position.

Each opening 7 is provided with clamping mechanism asv above` described, andeach clamping mechanism is adapted Ito receive and hold a blank While the latter passes between the cutters.

The blanks are placed on table 12, one within each opening in table 1. As table 1 revolves and table 12 is stationary, the tendency is, of course, to carry the blanks against the rear walls of the opening 7. As they move toward the cutters 13, they pass under the presser bar 24, sho-wn in detail 'in Fig. 6. This bar is provided with a rounded nose, on the end toward which the blanks,

are approaching and is considerably longer than the width of the blank. It 1s carried pass loosely,v

by twol rods 24a which latterthrough the frame 24", which, as Shown in Fig. 3 is adjustably secured to table 12, by bracket 24C., and is of course verticallyadsaid table 12. 'Frame 24" also carries a series of wires or equivalent devices 24d, the lower ends of as to engage the sides of the handle blank, and force it solidly over against the rear `Wall ofopening 7, 4while thev pres'ser bar 24 forces the handle blank onto 'the table 12, iii

`the event it should happen to vbe misplaced.

J ust before'the blanks pass over, or fron ,the end ofv table 12 adjacent the cutters, an

after they have been 'acted upon by the presser bar 24 and wires 24d, shaft 20 is partly turned by the engagement of one arm with stop 23. This part rotation of the shaft carries the clamp j members `14*15 toward the end of the shank of the blank and firmly clamps same between'jaws 11 and 15a. The blank is slightly thicker than the'thickness of table .1, and table 12 is, so located with reference to table 1, that the blank will project equally above and below table `1.

The blank thus placed and These plates are arend with av which are so located 20h sh release the clamping jaws, partly iinihed blank to fall cle placed under tablel 1.

In the event the blanks should stick to one or both of the jaws, after the pressure against theclamping jawhas been removed, I have provided an ejector which consists of an arm 25 pivoted to a support 26 and provided atitsfree end with a fingerl 27, adapted as the table 1 is rotated, to drop iand disft20rand. turns cam 19 in adirecti'on to and permit the into a receptaengages v table 1 as the latter rotates and mitting the arm 25 to fallv and car-ry its finger 27 intocontact with. the blank. In

contact with the side Walls of'openings l7, it is pivoted to arm 25 and is yieldingly held in position by spring 27a. With this machine it is simply necessary for an attendant to feed the blanks 9 onto table 12, through the` opening 7 in table 1, after which the lentire o erationis automatic.

.In or er to prevent the table from vibrating orwabbling, I support the same and below, adjacent the cutters, by the guides 27 b., These guides are curved, as shown in Fig. s eachy is supported adjacent its ends by the rods 28 mounted in bearings in bracket 29. These rods 28 are provided with collars28t which hold them against vertical movement and each has a threaded connection with one end of a guide, so asto permit the latter to bel accurately adjusted up or down to com pensate for wear and also to be adjusted for tables of different thicknesses. f

By means of the handles 20a/on shafts 20, the latter can be turned by hand at any time` to cause the movable clamping jaw-to disen,-

ga e or engage a blank.
