IMPROVEMENT IN MACHINES FOR CUTTING FAN-STICKS.

Specification forming part of Letters Patent No. T6637 1, dated August 10,1875; application filed June 24, 1875.

To all whom it may concern:

Be it known that I, JOSEPH W. WHITE, of Weymouth, in the county of Norfolk and State of Massachusetts, have invented an Improvement in Machines for Cutting Fan-Sticks, of which the following is a specification:

This invention relates to improvements in mechanism for cutting fan-sticks and consists in the combination, with the rising and falling die, of a loose movable support for the material, from which the sticks are cut, and with feeding mechanism for moving the support and material under the action of the cutters; also, in the combination, with the reciprocating carrier for the die, of a fan-stick receiver attached to the die-carrier; also, in the support combined with a bed plate and an adjusting mechanism, whereby the height of the bed-plate may be adjusted or regulated with reference to the die, substantially as set forth; also in the particular construction of the die.

Figure l is a top view of my invention Fig. 2, a plan of the cutting-die; Fig. 3 a side elevation, and Fig. 4. a detail of construction.

The frame a. of'the machine is of a shape to properly sustain the working parts, and mounted therein is a crank-shaft,.b, provided with a balance-wheel and driven by power. This shaft b is provided with cranks or. eccentrics, to which are fitted links 0 jointed at d to the reciprocating carrier 6, guided through the uprights of the frame, and having connected with its lower side the holder f of the fan-stick cutting-die g, which is an endless spring-knife in the shape of the fan-stick, and which is attached to the holder f by screws h 2', those h bearing only against the outer sides of the cutter to confine it in position, and those '5 entering screw-threaded openings in the cutter to move its sides j in or out to contract or widen their distance apart, as it-is desired to make the neck of the fan-stick, as at k, narrow or wide, and this feature of adjustment of the cutter is of great importance. The bed 1 of the machine is provided with projections m that grasp the upright of the frame, and the bed being guided, is adapted to be raised or lowered, as required, by the adjusting device (shown as a wedge, n) fitted to the frame and the lower side of the bed l, and

this journal also carrying a toothed gear, a,

moving with the ratchet. This gear a engages a gear, w, supported below it, and each gear a 10 engages gears a: w on the ends of the feedrollers y, the upper of the feed-rollers being connected with the journal, supporting ratchet t by links z, which permit the upper roller to rise or fall with relation to the lower roll fixed in its bearings, so as to permit the introduction of the loose movable support a, which is preferably a plate of wood of proper size to support the veneers or thin pieces I) of wood, from which the fan-sticks are cut, the cutter usually cutting through several thicknesses at one operation. The upper feedroller is held pressed against the material be tween it and the lower roll by links 0, having springs d and adjusting nuts 0 The feed-rollers, after the supporting-board a and pieces are grasped between them, present the material automatically to the action of the cutter g, the movement of the pawl-carrier r controlling the extent of the feed movement according to the width of the fan-stick being cut. This board a is found of great value in presenting the material to the action of the cutters, as it is light, easily moved, is readily and firmly grasped by the feed-roller on which it rests, and will not dull the cutter-edge, and as the board becomes worn, and consequently reduced in thickness, the bed Z is adjusted by the adjuster n. An opening or channel, f, is made through the piece 0 in line with the cutter g for the discharge of the fan-sticks through the top of g, and the inclined portion 0 of e deflects the sticks into a stick-guide, g, from which they drop into a box or receptacle placed to receive them.

I claim- 1. In a fan-stick-cutting machine, the combination of the reciprocating cutter-carrier, cutter g, and bed with feed-rollers and loose support, moved by the feed, and adapted to support and present the fan-stick material to the action of the cutters, substantially as described.

2. The reciprocating carrier for the cutter,

provided with an opening, f, for the dis-gcharge of the fan-sticks from the top of the cutter g, substantially as described.

3. The cutter-carrier 0,, provided with open-;

ingf, in combination with the fan-stick guide g to receive the fan-sticks as discharged from the holder, substantially as described.
