To point the ends of the dowels and to cut the same oif from, the rod, I provide a rotary cutter 29 and a saw 30 arran d o posite each other at the respective si es o "the rod and close to the end of the mandrel. 100

'mounted on the-yoke to ad'ust'the saw and .'Ilhese pulleys' are engaged by a driving belt'36 extending over the same and beneath an idler 35 mounted ulley 37 mounted on the driving shaft 2. VTo engage the fcutter 29 and saw 304 alternately and atv proper time with -the dowel rod, the yoke 1s pivoted von the frame to oscillate and alternately engage the cutter and saw with the work and provided with a suitable groove in a cam wheel 41 moui'ite on a counter shaft 17 journaled-in the frame,
4 This groove holds the yokein mid-position during about one half of there'volutionand oscillates the yoke to rstengage the cutter and then to engage remainder of the revolution of the cam wheel. This counter shaft is driven by bevel gears 21 on a jack shaft 20'L driven by a sprocket. wheel 20 engaged bya chain A19, saidchain being driven by a wheel 20 from 2A connecting it with the driving s aft 2.
On the `jack shaft 2 0 is .another sprocket by. a chain 22 to the shaft carrying the crank Wheel 20b from which motion is imparted wheel14 and having a sprocket` wheel engaged by' said-chain. The wheels 20b and 23 are of the same size, whereby '.Wheels41 and 14 rotate synchronously, and
the cam groove in the wheel 41 is so adjusted that the yoke stands in mid-position 'with .the cutter and saw out of operative position during that part of the revolution -mand'rel 1 by an of tliewheel14, which causes the sleeve -6 to move forward and feed the rod forward in the machine.
Toreceive the dowel after has-been cut fromthe rod and carry .it outside the machine,` and to steady the end of the rod while being cut aA tube 27 is held in line with the arm 28 attached to the frame of the machine and the end of the mandrel and that of the tube 27 adjacent to the cutting toolsare provided with removf able and interchangeable bushings 25 and 26 of diierent openings t'o ada t lthe same to properly engage and holdrox of different sizes.
