MCOLINTOCK YOUNG, OF FREDERICK, MARYLAND, ASSIGN OR TO THE DIAMOND MATCH COMPANY, OF CONNECTICUT.

MACHINE FOR CUTTING AND FILLING MATCH-SPLINTS.

. SPECIFICATION forming part of Letters Patent No. 415,934, dated November 26, 1889.

Application filed May 29, 1889.

T0 aZZ whom it may concern:

Be it known that I, MCOLINTOOK YOUNG, a citizen of the United States, residing in the city and county of Frederick, in the State of Maryland, have invented certain new and useful Improvements in Machines for Cutting and Filling Hatch-Splints, of which thefollowing is a specification.

My invention relates to a class of machines in which a series of match-splints are simultaneously severed from a strip or veneer of a thickness equal to that of the splints and of a width equal to their length. Each alternate splint is then shoved endwise transversely to the line of feed a sufficient distance to separate the ends'of the splints for dipping, thus forming a double-edged comb, which by a further continuance of the endwise movement is inserted between the bars of a frame traversing transversely the line of movement of the comb, so that each comb is in turn inserted between its respective bars of the holder-frame.

The object of the first part of my invention is certainly and effectively to feed the strip to the cutters. These ends I attain by causing the edges of the strip totr'avel in fixed guides while its opposite faces: are acted upon by a feed-roller, and by a pressure-roller capable of yielding to accommodate itself to variations in the thickness of the strip,while always maintaining a bite thereon.

The object of the next part of my invention is to adapt the cutting mechanism to the efficient performance of the work, which end I attain by employing a series of independent cutters adj ustablymoun ted in a'common head, which head is in turn adjustable in suitable guides, so as to compensate wear and secure the necessary relation of the cutters to the other parts of the mechanism.

The object of the next part of my invention is to form the splints into a double-toothed comb, which end I attain by holding each alternate splint by means of a friction brake or stop and shoving the intermediate ones endwise a sufficient distance to form the teeth of the comb by a pusher-rake moving in a plane parallel with but tramverse to the line of feed.

The object of the next part of my invention Serial No. 312,541. (No model.)

is to fill a frame with match-splints properly arranged for dipping, which end I attain by shoving the comb, formed as set forth in the preceding paragraph, endwise a further distance by the continuance of the movement of the same pusher-rake as that which formed the comb, thus inserting the comb between the yielding bars of a holding-frame transversely traversing the line of feed and that of the motion of the comb, so that a series of the combs are thus inserted in the holder.

The object of the next part of my invention is automatically to traverse the holdingframes across the line of feed of the combs, so as to insure .their proper and successful insertion therein, which end I attain bycausing the holding-frames to traverse in guides actuated by pawls acting directly on the holding-frame;

The object of the next part of my invention is to provide a splint-holding frame in which the splints will be securely held, and from which they can readily be removed when desired, which end I attain by constructing the splint-holding frame of parallel holding bars or clamps held in proper relation by the side pieces connected therewith by detachable fastenings, so that one of the side pieces may readily be detached to permit of the removal of the splints from their holding-bars by shoving them laterally sidewise.

My invention further consists in certain constructions, combinations, and organizations of the above-mentioned instrumentalities with other mechanism hereinafter described, the subject-matter of which is hereinafter specifically designated in the claims at the close of this specification.

My invention contemplates the simultaneous formation of a n umber of splints from a continuous strip or ribbon of wood cut from the log and dried. The advantage of this is that hard or interior wood can be successfully used and rapid but thorough seasoning secured. Short strips or blanks may, however,

be used in connection with my improved machine, if desired. I

In carrying out my invention a blank or strip of a width and thickness equal to those of the match-splint desired to be produced is fed beneath a grating of bars arranged par allel with the splints when cut. A series of reciprocating knives passing between these bars simultaneously sever a number of splints. A brake or friction-clamp bears laterally on each alternate splint thus formed, while a pusher comb or rake moves in a plane parallel with the splints and shoves the alternate ones endwise a sufficient distance to allow of the proper dipping of the splints, thus forming a double comb. A continuance of this motion then shoves all the splints, or the enthe comb, between clamping-bars of the splint-holder frame traversing across their line of feed, which frames travel'in suitable guides to a proper receptacle. The splints are then dipped in the usual way.

The unfilling or removal of the splints from their clamping-frame, either before or after dipping, may be automatically effected by mechanism shown and described in a pend ingapplic'ation, Serial No. 312,510, filed siin ultan eously herewith.

The accompanyin drawings represent so muchof a machine embodying all my improvements as is necessary to illustrate the subject matter herein claimed. Some of these, however, may be usedwithout the others and with machines differing within certain limits in the form and construction from those herein shown.

The driving-shaft side of the machine I call the back, and the opposite or cutter side the front. That end of the machine on .the right of a person facing the front I call the right or feed end, the opposite the left or discharge end of the machine.

Figure 1 represents a top plan with the striproll omitted; Fig. 2, a vertical transverse section on the line 2 2 of Fig. 1, looking to the left or discharge end of the machine, as indicated by the arrow, showing more particularly the cutting and holding frame feed mechanisms; Fig. 3, a front view showing the striproll,in dotted lines; Fig. 4, a right end elevation Fig. 5, a left end elevation; Fig. 6, a vertical longitudinal sectionthrough the cutterhead on the line 6 6 of Fig. 5; Fig. 7, a detached plan showing the method of forming the splint-comb; .Fig. 8, aperspective view of the cutter-head as seen from below; Fig. 9, a perspective of the grating between which the cutters work; Fig. 10, a vertical longitudinal section on the line 10 10 of Fig. 2, showing the friction brake or stop which acts on the splints; Fig. 11, an elevation of the inner face of one form of splint-holder frame; Fig. 12, a vertical longitudinalsection therethrough on the line 12 12 of Fig. 11, and Fig. 13 a horizontal transverse section therethrough on the line13 13 of the same figure; Fig. 14, a side or edge View showing the mode of inserting theiholding-bars of the side pieces of the splint-frame; Fig. 15, a detail view on a smaller scale, being an elevation of the inner side of.the holder-frame withits parts detached, to show their method of connection and disconnection more clearly.

The drawings show the entire mechanism mounted in a suitable bed-plate or main frame A. A driving-shaft B, turning in usual bearings, is driven from any suitable prime ,mover by well-known meanssuch as a fast ,and loose pulley B at one end, the other end carrying a balance or fly wheel B to equalize the motion of the various parts. i

A face-cam C on the feed end of the machinedrives a friction-roller c on an arm or frame C, rocking on pivots c on the frame. The free end of this arm is slotted to receive a pivot-pin c on the free end of a radius-bar C pivoted on the shaft d of the feed-wheel D, and carrying a spring-pawl c acting on a ratchet-wheel O", which actuates the feedwheel, to which intermittent motion in one direction is thus imparted.

The drawings show the feed-wheel as turning in fixed bearings, with the ratchet-wheel integral with or secured to it, and with an annular groove (1 in its periphery, for a purpose hereinafter explained.

Fig. 3 shows in dotted lines a reel or spool E, upon which the strip 6 is wound, from whence it passes under a guide-roller E, be tween parallel guides E E longitudinally grooved on their inner faces to receive the splint-strip. (See Fig. l.) I The outer ends of these guide-bars are clamped by set-screws between holding-bars 6 6 while their inner ends are similarly held by slots and setscrews 6*. This organization enables me to adjust the guides to strips of varying width. The inner guide-bar E it will be seen, lies in the annular groove cl, tangential to the surface of the feed-wheel, the result being that the feed-wheel D extends up between the'guides and bearson the underside of the splint-strip as it is fed to the cutters. (See Fig. 4.) A pressure-roll F is mounted on a shaft f, the journals of which traverse slots f in the frame. Springs F bear on, these journals, their pressure thereon being regulated by a set scr'ew F The pressure-roller is thus held down upon the splint-strip to insure the. proper bite and feed, and is free to yield to accommodate variations in the thickness of the strip, which is thus securely held on all sides while being fed to the cuttors.

The splint-strip is fed over a cutter-block G until it abuts against a suitable stop g in the guideway. This block is preferably of Wood or some equivalent resilient material. It is securely held in place laterally by a guide-slot in the frame and by a holding-bar G, removably secured to the frame by clampscrews g. A metal plate g unde'r the cutterblock rests on adjusting-screws G G by which means the cutter-block, while rigidly supported, is rendered adjustable vertically to bring it in proper relation to the other mechanism. A grating H, Figs. 2 and 9, provided with parallel bars 72 transverse to the line of travel of the strip, is mounted 011 the frame over the cutterblock, so as to leave IIO room for the strip to pass under it, the strip lying between the cutter-block and grating while the splints are severed.

The cutter I is composed of a series of parallel flat endwise-adjustable blades 1' in a recessed cutter-head I, being held laterally therein by suitable bearing-bars i i and clamp-screws 1' t Set-screws I passing through the top of the cutter-head, press these blades endwise into proper position, each cutter being separately adjust-able by its own screw. The cutters lie parallel with and work through the spaces of the grating H to sever the splints. (See Fig. 6.)

The cutter-head I is adj ustably held in a stout frame J 2 by set-screws l passing through a bearing-bar 1 The frame is further strengthened by a cross-bar I The cutters are thus firmly held against working strains while readily removable or separable. The cutter-frame is mounted on an arm J rocking on a pivot j. An eccentric-link J on the driving-shaft is connected with this arm by a pivot j, to actuate the cutters. Adjustable guide-stops J 3 on the frame limit lateral play of the cutter-head and keep the cutters in correct relation to the grating. A cam K on the drivingshaft vibrates a friction-roller it on an arm K, rocking on a pivot and connected at its free end by a pivot K to a pitman K adjustable in length by a screwcoupling 70 of well-known construction. A pin Z connects this pitman to a slide L, movable endwise in guides Z on the frame. The front end of this slide carries a pusher-rake, consisting of a fiat comb L, the teeth Z of which are of a distance apart about equal to the Width of the splint or to the spaces between the cutters, the depth of the teeth being about equal to the distance it is desired to move the alternate splints to form the comb. The rake may be removably attached to the slide to permit of the insertion of rakes having longer or shorter teethto move the splints the desired distance. The rake moves endwise in the plane of the splint-strip transversely to its line of traverse in order to intersect and move the splints endwise into the holder. 7

One set of splints is simultaneouslysevered by a single stroke of the cutters in one direction while held between the cutter-block and grating. The cutter then withdraws and the rake advances, pushing all the splints endwise until the ends of the alternate splints pass under the teeth at of a brake or friction holder M, Fig. 10, which bears on the alternate splints n, hard enough to hold them, while the others it are shoved endwise far enough to form the comb N, Fig. 7. The friction-holder M, it will be seen, rests in a slot in the frame, being held against accidental the pusher-rake shoves theentire comb endwise and inserts it between the bars of a holder-frame O. This frame may be made in various ways; but the preferred construction is that shown in Figs. 11 to 15, which consists, essentially, of a frame composed of side and end pieces and intermediate bars, between which the splints are held. The end pieces 0 are fastened to the side pieces 0 at one end, but removably connected at the other. The holding-bars O are likewisefastened at one end to one of the side pieces and detachably secured to the other. They may all be fastened at one end or secured alternately to opposite side pieces, as shown.

The holding-bars are preferably made in the way shown in Figs. 11 to 14=that is, with elastic or yielding sides between which the splints are inserted and held. The yielding surfaces are shown as composed of metal C-shaped springs 0 secured centrally to each alternate holding-bar, the splints thus being held by spring-pressure on one side. against the solid side of the adjacent bar.

An eccentric P on the driving-shaft is connected by an adjustable link P with a crank P on a rock-shaft P mounted in suitable bearings in the front of the frame above the cutters. It in fact has its bearings in a guide-frame R, secured to the front of the main frame, and carries crank-arms p p, to which spring-pawls p p are hinged. These pawls engage with the holder-frame O, or with their bars, and feed them step by step athwart the line of traverse of the combs of splints, which are successively inserted between their appropriate bars.

The holder-frames traverse in a stationary flanged guideway R. They are prevented from being pressed away from the pusherrake by lugs r on each side of the guideway, and are in like manner prevented from passing too rapidly across the line of traverse of the rake by a friction-bar R held by screws 0' and rubber springs r which allow it to yield slightly when required.

The filled holderframes pass from the straight part of. the guideway to and through its curved end or spout R which discharges them into a suitable receptacle.
