Description
I I so as to cut the articles made upon the machine to the size required whether larger, the same size, or smaller than the patterns. The carriage is traversed by the screw r which turns in the box s fastened to the bar G and in a hole fitted for it in the opposite side of the carriage; this screw has the, worm gear t fastened to it which' is actedV upon by the screw L to turn the gear and screw r in the nut n which nut is held in its position between the bars lA A `by the brackets 'v o fastened to the bar Iw whichl .brackets b fastened to the bar A so that it may be raised and lowered to tighten and loosen the belt c from the-pulley e on the shaft e to the pulley f on the shaft U. The traversing bar a. has' a score in it so that it can be hooked onto the bracket b" and leave the belt c so loose that the shaft e and nut fn will cease to rotate and the carriage willV be moved by the screw 1; but if the bar a is unhooked and allowed to drop down it tightens the belt c which operates the shaft .e so as to turn the nut n by the band just as fast as the screw r turns and stops the carriage. l
The cutter bar e may be made in the form represented or of such other form as may be desirable and provided with one or more cutters h for each piece of wood to be cut, and these machines are usually made to cut ten at once but may be made to cut such a number as may be desirable. Fig. 4 represents a two edged cutter such as have been advantageously used in these machines.
The machine having been constructed and completed as above described, the carriage is placed by operating the screw r so that the cutter bar e is near the bar G and under the dead centers J which are drawn back and the pieces of wood to be cut, are placed upon the spurs of the arbors I-I and the dead centers pressed forward into them and secured by screws like those represented g. These pieces of wood should be a little shorter than the pattern so as to be cut the entire length without carrying the patterns past the boxes z' i either way; when they are all properly arranged the machine Vmay be set in motion and the pieces of wood will be turned by the arbors and cut into the form required by the cutters. The
v pieces of wood may be traversed across as many times as may be desirable.
I contemplate that two cutters to operate upon the same piece of wood may be fastened to the same cutter bar and one of them set a little higher than the other so as to follow it and finish the work. Or two cutter bars may be used side by side and operated in opposite directions, so that the stroke of one cutter will counteract the other and in this way small articles or those which are comparativelyslender may be cut wit-hout the inconvenience of a back rest. Besides I contemplate arranging a cutter bar and cutters so as to be operated by the same patterns above the pieces to be cut and making the cutters to cut i'n lan opposite direction, and at the same time that the cutters do below, so that the tendency of one cutter to spring the article cut will be counteracted by the other so as to cut very slender articles without a back rest. Also to give the blocks of wood an intermittent motion or the pieces to be cut and the patternsso as to let them stop while the cutter is cutting, or to move them faster as may be most desirable. And further by using a screw with the thread cutin one direction to turn the pattern and in the other to turn the pieces to be cut a left hand last may be cut from a right hand one or vice versa. And by making the gears which turn the patterns of one size, and the gears which turn the pieces to be cut of another, a spiral post or other article can be cut from a straight pattern, and thereby save the expense 'of making a spiral pattern, or a piece may be cut vmore or less spiral than the pattern. Also that the machine may be modified in various ways to suit the different circumstances and purposes for which it may be used without departing from the principles or merits of my invention.
This machine costs far less than any Vother machine or number of machines to do the same amount of work in a given time and will require far less labor to tend it as ten pieces to be cut are vput in and taken out at each time the machine is stopped and started. Besides the dist-ance between the cutter bar and patterns can be varied by the operator while the machine is in motion so as to make the article cut the size required,
whether larger the same size, or smaller than pattern.
The cutter is traversed in a straight line and make a more uniform surface which can be finished with one half of the labor and expense required to lfinish the surface cut by a rotary cutter. Besides a rotary cutter forces the piece cut from the Acenter of motion and it springs back beyond its natural or proper position so that more than the required quantity is cut oli'. But my reciprocating cutter springs the article cut nearly in the same line which it moves, and therefore makes a much better and more perfeet surface upon the piece cut; besides there is not the same occasion or-necessity for a back rest.
