Specification of Letters Patent.

Patented May 21, 191%.

Application filed April 14, 1917. Serial No. 162,052.

To all whom it may concern:

Be it known that I, HARRY KELLEY, a citizen of the United States, residing at Wilmington, in the county of New Castle and State of Delaware, have invented certain new and useful Improvements in Feed- Boxes for Match-Making Machines, of

which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to certain new and useful improvements in match making machines, and more particularly to mechanism for forming the match sticks or splints out of, strips of veneer in order to produce a square or round match stick with very little waste.

Another object of my invention is to provide a match making machine with a feed trough or box in whichthe strips of veneer are placed having operating. fingers for separating and guiding the strips of veneer into position to be cut into splints by the cutters of the cutter head.

Another object of my invention is to provide novel means for holding the strips of separated veneer in the feed box adjacent the cutter head by-interchangeable plates in order to allow match sticks of different lengths to be formed.

I am aware that I am not the firstin the art to form match sticks or splints out of veneer, but in prior devices it was necessary to provide splitting knives to produce the sticks, while with my device any number of strips of veneer can be placed in the feed box or trough and intermittently fed in position to be out by thezcutters into match splints whereby I am able to form square or round match sticks with very little waste.

It has been found in practice that it is impossible to separate strips of veneer by separating fingers unless the line of separating fingers extends obliquely across the feed box or at an angle to the line of feed as these strips are held in contact with one another in the feed box under pressure, and unless these strips are brought into engagement with the space fingers in stepping relation with one another, the fingers will not sepa rate the strips as it is impossible to arrange the fingers to register with the space he thicknesses of the veneer strips as the variation of one hundredth of an inch in the thickness of any one of the strips will throw the entire series of sticks being fed in the box out of alinement with the spacing fingers which at once causes the strips to jam in the box.

Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended dawns.

In the drawings,

Figure 1 is a top plan view of my improved construction of feeding mechanism for a match making machine showing the same arranged on one of the well-known types of machine of this character now in use;

Fig. 2 is a top plan View on a large scale showing the pressure plates for holding the veneer strips tightly in contact with one another;

Fig. 3 is a section taken on line 3-3 of Fig. 2; and

Fig.4 is a detail side elevation of a portion of a trough showing the manner of mounting the corrugated feed rollers.

Like numerals of reference refer to like parts in the several figures of the drawing.

My invention is capable of being applied to any of the well-known forms of match making machines now in use and in the drawing I have shown the application-0f the same to a Beecher type of match making machine in which 1 indicates a frame, 2 the cutter head, and 3 a series of cutters employed for forming the splints. My invention diifersfrom the Beecher construction thus far described by the application of cutting knives having square cutting holes with a single cutting edge as it is only necessary to cut the veneer vertically as three sides are already formed. This particular construction of cutter knife, however, forms the subject matter of a companion application filed even date herewith.

My invention consists of substituting for the ordinary trough or box used for feeding the blocks to the cutting head in the Beecher type of machine, a trough 4: which terminates at the delivery end therein in a curved portion 5 which is provided with a plurality of curved spacing fingers 6 terminating on a line oblique or 011 an angle to the line of feed, said fingers forming intermediate guide grooves 7 through which the strips pass and are fed into the path of travel of the cutters 3 of the cutter head which Cutters are operated intermittently so as to sever from the strips of veneer fed thereto splints which are operated on and delivered to the splint-engaging members of the endless conveyer in the ordinary manner the setter pins loosening the sticks so as to allow the sticks to be readily drawn out of the cutters when engaged by the splint engaging member of the endless eon-veyer.

Disposed above the feed trough are spaced corrugated feeding rolls 8 and 9 which are adapted to be driven intermittently in unison so as to feed the strips to the cutters, and these rollers are preferably adjustably mounted so as to accommodate different widths of veneer strips and are adapted to be driven and timed with the cutter head so that as the cutter head is raised vertically to deliver the splints cut to the endless conveyer, the strips of veneer will be advanced outwardly beyond the ends of the grooves 7 in the position to be operated on by the cut ters of the cutter heads as the same descends.

In order to provide means for holding the strips of veneer tightly in contact with one another in the feed box or trough 4L, I provide the opposing walls of the feed box with spring-pressed plates 10 and 11 so as to compensate for any variation in the thickness of the strips of veneer.

Arranged over the spacing fingers at the delivery end of the trough is a pressure plate 12 which is provided with a series of ribs 13 adapted to extend into the grooves 7 so as to hold the strips of veneer in position to be operated on by the cutter head, and by providing plates with ribs of different lengths match sticks of different lengths can be formed on the same machine without changing the construction in any way, as it is only necessary to have interchangeable plates for holding the strips of veneer in I position to be operated on by the cutters.

By referring to Figs. 1 and 2 of the "drawing it will be seen that the spacing fingers terminate on a line drawn obliquely through the trough, and as the strips of veneer have a rectilinear movement in the feed box before they reach the spacing fingers they will assume at their ends a stepped relation so that the spacing fingers can readily pick up the strips and separate the same so as to guide the strips into the curved grooves, and as the feed of the strips is continued they will be brought into position to be operated on by the cutter head. When the strips of veneer are placed in the portion 4 of the feed trough or box, the ends are in transverse alinement, and as they are advanced intermittently by the feed rollers, the strip lying adjacent the plate 10 will be picked up first or separated from the remaining strips by the spacing fingers which are lying adjacent that wall, and on the next movement of the strips the next strip will be picked up and guided into the proper groove, this being continued until all .of-the strips have been guided into the grooves. As the strips are drawn by the continuous movement the strip lying adjacent the plate 10, of course, will be advanced in position to be operated on by the cutter head before the strip lying adjacent the plate 11, but after the machine has operated a hort time the strips of veneer assume a line parallel with the line of the cutter head so that all of the strips will be operated on simultaneously by the cutter heads so as to provide match splints corresponding in number to the strips or veneer arranged within the feed box.

By constructing the square match sticks or splints out of strips of veneer which are fed to the cutting head when in vertical position I am able to dispense with the use of blowers, trimming knives, or any other means for finishing the splint and square match sticks which are produced with cutting knives having only one cutting edge, as when the stock from which the splints are formed advances into the position to be cut by the cutting knives of the cutting head by forming the stock of strips of veneer three sides have been previously cut. This enables match sticks to be formed very cheaply as any waste is entirely eliminated and the match stick or splint is produced without refinishing the same.
