WOOD-TURNING MACHINE.
Application filed May 1925. SerialNo. 27,952.
This invention relates to machines for turning handles such as used for brooms. mops, hoes and the like, and more particularly to the mechanism for pulling the hanb dle through the turning mechanism, and my object is to provide apparatus of this nature which will provide a positive feed for handles having irregular contours.
I attain my object by means of the constructions hereinafter described and illustrated in the accompanying drawings, in which v Fig. 1 is a side elevation of part of a machine showing the pulling and feeding mechan sms in section;
Fig. 2 an end elevation of the left hand end of the pulling mechanism shown in Fig. 1; Fig. 8 a cross section on the line 3 3 in Fig. 1;
Fig. 1- a longitudinal section of a feed roller and spindle with other parts shown in elevation, the direction of view being along the line R Q in Fig. 2 at right angles to the line Q, P, the line Q R indicating the longia tudinal center line of the spindle;
Fig. 5 a detail in side elevation of part of the pulling mechanism;
Fig. 6 an end elevation of the spring guide;
and
Fig. -8 a cross section on the line 88 in Fig. 6.
In the drawings like reference numerals indicate corresponding parts in the different figures.
1' is the base of the machine suitably.
shaped to support the difierent, parts. The
ner, past a roughing cutter 2 which carries a threading cutter 3 which cuts a slight thread below the roughly turned periphery These openings are tapered at 8? to faci1istick 1 is rotatably fed, in any suitable man- '9towards one another.- Adjusting screws are provided for the springs whereby the compression of the latter may be adjusted to firmly hold the stick without causing any jamming while the finishing cut is being made thereon.
The finishing cutter 10 is located between the thimble 5 and guide 6. Thecutters 2, 3 and 10 may be driven in any suitable manner and as they form no part of this invention they are only partly shown and briefly described.
As the turned end of the stick passes through the spring guide it is engaged by the pulling mechanism I shall now describe. On the base 1 is secured, by means of bolts or screws 11, a frame 12 on which are mounted three feed rollers ab and a secured to the ends of spindles'a Z2 0 These spindles are journalled in supporting members a 6 and 0 having spaced lugs a 6 and 0 formed on or secured to their ends remote from the feed rollers. These lugs. are jourend of the latter adjacent the feed rollers is bored out to receive an annular disk 13 havv ing guides 07', Z) and 0 adapted to receive Fig. 7 a horlzontal section ofthe same,"
slides a b and 0 formed on or secured to the supporting members. In each guide is carried a spring 14 adaptedto engage the slide therein for yieldingly maintaining each feed roller in engagement with the stick.
The axis of each spindle is set at an angle to a plane in which lies the axis of the stick 1 and the line of contact of the roller with the stick whereby the rollers are set to feed the stick, when suitably driven, at substantially the same speed as the threaded guide 4.
The aXes of the spindles a 6 and 0 are also spaced from the axis of the stick and arearranged in equi-angular relationship to one another. From the constructions described it .follows that the bearings a, b,
and c are tilted in a direction longitudinal of the axis of the stick to enable the adjacent ends of the bearing pins to'overlap.
The feed rollers are driven by a skew gear 15 secured to a-hollow shaft 16 journalled at its forward endin ball bearings carried by the frame 12. Q The rear end:- Of -this shaft ed telle th a iii nim v1 is journa lle'd, by means of ball bearings, carried in an end member 12 of the frame. sleeve 17 passed through the disk 13, frame 12, shaft 16 and member 12 forms a continuous and unbroken channel for the stick to pass through these parts. At the ends of the spindles remote from the feed rollers are secured spur gears o 7f and 0 This arrangement of using a skew gear meshed with spur gears enables each spindle to healso set at an angle to the axis of the sleeve 17 in a plane at right angles to the hereinbet'ore mentioned plane.
Referring particularly to Figs. 1 and 3, it will he noted that the bearings (r312 and c are equ-i-ang nlarly arranged so that their axes intersect thepitch circle of thejskew gear 15 at the median plane thereof, which Iar raligement permits a radial movement of the p I g1 ent of the spur ears relative to thesjkew gear. I
.et e lc is i c ed t nd 3 which show the relative positions of the feed rollers atone end Q of the spindles and the gears at the other end It thereof. The line Q.VR thus indicates the center line of the spindle.
The hollow shaft 16 driven by means or a train of gearing 18 adaptedto be driven by a pulley 19. The 1ran 1e12 and member 12 are connected by a sheet metal hood 12 which forms a cover for the hinge hearings and gears.
The mode 0t operation, assuming the stick is being rotatahly :ted past the roughing and threading cutters 2 and 8, is as follows. Vhen the tread. in the stick engages the threaded guide 4-, the latter, assuming the stick is be ng rotated, feeds it towards the finishing cutter 1 0 and the feed rollers a, b and 0. These rollers have their peripheries tormd as knurled tires with their corners ch-anitered oil to facilitate the entrance of off the stick between them and are adapted to pull or feed the rear end of the stick past he finishing cutter after it has been disengaged by the threadedgu'ide 1.
