H PATTERSON MATCH SPLINT MACHINE.

No. 7,867. Patented May 14, 1850-4 HORACE PATTERSON, OF BALDWINSVILLE, MASSACHUSETTS.

i, SPLINT-MACI-IINZE.

t specification of Letters Patent No. 7,367, dated May 14, 1850.

To: all whom t may concern .Be it known that I, HORACE PATTERSON, of Baldwinville, `and the county of Worcester and `Stateof Massachusetts, haveinvented certain .new and useful or `Improved `lVIachinery forMaking Cylindrical Splints for Friction or other Matches or `for Various other Purposes; and `I do hereby declare that the same isfnlly described and represented in the following 4specification and the `accompanying drawings, letters, figures, and references thereto.

` `Figurel, ofthe said. drawings denotesz ai' front view` of the cutter stock or that part of a match splint making machineto which my `improvement is applied. Fig. 2, is a horizontal section of it. Fig.v3,'is a rear elevation of it. Figfl, isa. transverse section of it taken throughthe series `of rounding cutters. Fig. 5, is a side edge view of the collection of rounding cutters and is drawn on a scale three times greater than they are ordinarily used. Fig. 6, is a front end view of such collection of cutters and is drawn on a scale three times as great as they are ordinarily constructed. Fig. 7 is a horizontal section on said enlarged scale taken through one of the cutters. is a similar horizontal section `taken between two of the cutters. Fig. 9, is a rear side view of the collectio-n of cutters exhibiting the waste passages thereof.`

In the said drawings, A, denotes the cutter stock andiB, the frame usually applied to it for the purpose of holding the dipping boards, C, and D, are two plain facesor plates against which the block of wood,

from which the splints are `to be separated is borne and moved. The faceC, is placed a little in advance of the face D, as seen in, Fig. 2, and is arranged between it andanother face or plate E, on which are made` the grooves or passages which receive the splints from the cutters `and direct them into the dip-ping frames. Such grooves or conducting passages and dipping frames are substantially described in the specification of the Letters Patent granted on the 26th day of April A. D.1845, to Asa Fessenden and Luke L. Knight. My invention although it may be used in connection with such directing passages and dipping frames may also be use separate therefrom.

Through the plate D, and near its connection with the plate C, a passage b, (see Figs. 1, and 2,) is made for the reception of Fig. 8,

a plane iron c, `whose cutting edge is placed in the plane of the external surface of the plate; c. The collection of cutters 6,16, e, by which the cylindrical j` splints are made are arranged in andproject fromthe plate C, as seen in Figs. 1, and 2, they being held in placeby a set screw d. i

. Each cutter consists `of a short cylindrical` or slightly conicaltube which is` connected to a bar ,if (see Fig. `10, which represents an edge view of one of the said` cutters) by a thin rib g, whose `front edge or that imrnedatelycontiguous to the cutter edge is made sharp so` asto cut. `The front end of the said cutter is also made sharp so as `to cut. On 1each side of each'cutter e, and "at `ninety degrees Idistant from it, is another th'm cutting edge or wing as seen at "It, Flg. l0. When the several cutters are put together spaces or passages z', i, z', will be found in rear of them the said spaces or passages being intended for the escape of the waste wood, or that part marked f, f, f, in Fig. 1l, which is a cross section of a block exhibiting the manner in which the cylinders of wood and the waste wood are removed by the cutters and plane. The cylinders of wood or the match splints are seen, at 7c, 7c, 7c, and they pass through the cylindrical tubular cutter e, e, e,` and are separated from the block X, by them. The waste portions j", f', 7', &c, are at the same time detached from the block and one another by the several cutters or ribs g; and wing cutters L, it, before described, and as said portions are so separated they pass through the spaces or passages z', z', z', and escape throughj a passage F, made through the cutter stock and opening out at the rear side thereof.

The portions marked l, Z, Z, in Fig. 11, are removed from the block X, by the plane` iron c, during the next or succeeding forward movement of the block toward the cutters; such waste portions passing through the opening or passage Z), and escaping in toward and by the plane iron c, the Waste parts Z, Z, Z, are separated from the block, byV

the action of the said plane iron.

The grooves or passages made in the plate E, and which lead the splints to the dipping frames are represented by red lines in Fig. 1. They are also shown in section at m, m, &c., in Fig. 12.

In the collection of cutters seen in Fig. 5, it may be observedy that the passages for the escape for the first and last Waste pieces f, f", together With the Wing knives or cutters thereof should4 be made of a size or vertical depth suflicient to receive pieces j, f, of any vvidth'Which may be severed from any block. As the blocks generally vary in .thickness this precaution is necessary to prevent the jamming of the Wood in the said escape passages so as to choke the same, and

also to enable us to operate on a block Without the necessity of first very accurately reducing it to one particular thickness as is required to be done, When We operate by the hereinbefore mentioned machine, invented and patented by Fessenden and Knight and Which Was for making match splints square in cross section.

What I claim as my invention is l. Tlie combination of the circular or tubular'cutters e, e, their lateral Wing knives or cutters, their rib knives or cutters ZL, h, and the Waste escape passages for the Waste strips f', f', f, substantially in manner and for the purpose as above specified.

2. I also claim the improvement by which I am enabled not only to make round or 4cylindrical splints but, to introduce them to the dipping `frarnes--that is, I do not claim the combination of cutters dipping frames and passages leading from the cutters to the dipping frames, as these have been before invented and used for making square splints and setting them in the frames, Ybut I claim, in combination With the cutters for forming the round splints and passages m, m, for receiving them and conducting them to the dipping frames, the passages z', z', &c, F, for the escape of the Waste Wood or strips f, f', f', the saine being applied together and made to operate in connection With the reducing plane iron 0 and the plates C, D,

substantially as above specified.v
