Application filed NovemberlO, 1925. Serial No. 68,160.

This invention relates to that class of wherein blocks of wood are intermittently advanced end to end, in an oblique direction, to

tilt: path of a vertically reciprocating row of cutters operative to sever successive rows of splints from the opposing portions of the blocks and stick the splintsendwise into asuitable splint 1 carrier. U

In matchmachines of the class mentioned, the end of the trough in the region of the cutters, owing to its oblique relation thereto, is of tapering form,.and consequently the succeeding blocks, asthey are reduced by the action of the splintcutters,present a triangular or wedge-like formation. .The I leading or thin edge of the material, as well as the larger block sections must be held close up to the path of the cutters in order to ensure the eflicient actionof the cutters. Heretofore a spring bar has been arranged on the trough so as to overhang and bear upon the top of the blocks, adjacent the path of the cutters, but owingto the variations i i-height of the block sections uniform pressure of the plate thereon throughout the length of the cutting area, was not effected, and in the case of short blocks, or greatly reduced end blocks, the absence of effective pressure thereon resulted in the production of imperfect splints.

The object of my invention is to provide a simple. and efhcient construction whereby a uniform yielding pressure is eliicfently applied along the forward edge of the match stock in the region of the cutters, irrespec tive of the varying heightsor dimensions of the blocks within limits, which pressure is effectually maintained until the last match splint has been cut from each succeeding block To this end, my invention comprises a plurality of independent spring pressure devices of novel construction arranged to overhang and bear upon the tops of the progressing blocks throughout the portions thereof which are presented to the action of the cutters, as will be hereinafter described and claimed.

In the drawings W 1 Figure 1 is a sectional plan of a portion of a match machine having block-feeding mechanism equipped with pressure devices embodying my invention.

' Referring to the drawings, 10 designates a part of the main frame of a match ma chine, ll part of a vertically reciprocating head upon which is mounted a horizon tal row of

splintcutters

12, and 18 apart of the splint carrier.

14 designatesa horizontal trough formed or arranged on the machine frame so as to extend obliquely to the row of splint cutters, which trough is adapted to receive the blocks (B) of wood and guide them to the path of the cutters, as usual. The match blocks are arranged end to end in the trough and are progressively advanced therealong to the cutters by suitable feed devices, including the usual intermittently rotatable rolls 15. V

,In the present instance a double-feed trough whereby two parallel rows of blocks are directed to the cutters, is illustrated, but

a single row feed trough may be employed, if desired. I I

Overhanging the tapering delivery portion of the trough'are two series of resilient pressure devices 16, 17 provided with. depending nose portions 18 which are arranged to bear upon the tops of the two rows of blocks adjacent the front vertical surfaces that are presented to the action of the cut-v ters. These pressure de iccs are constitutec by the horizontal lnnbs 19 of angular metal sections whereof the vertical limbs 19 are Cit ti ti nose portions 18 of each series of preure liEtllllWlS are howled and rouinled, as a 215.

to itaciitate the tree passage thereunder ot the leading: portions ot the succeeding blocks ot the l'QFPGUt'lYO rows irrespective ot rariations in too height or size oil the htoclw. as the latter are advanced .in the cutting none. t lereral oi the end nose portions "which bear upon the. hauling); ends oi the blocks or ti 'meiu's oft blocks are snot-e ly beveled. as at 523-3. in order to ruesent gradually reduced contact surfaces ot proper sine to exert etlicieut steadyin y pressure up n the pro; 'e sirely small tapering: ends ol the sleet: until the last match splints have cut therefrom lzr the i,ttfllll'ttiiilt cutters.

Preterahly he overhanging terminal limb 1.9 o t each series oi'" sections has cut therein two spaced parallel slots ill. at dili'erent lengths which a tord three narrow pressure members adapted to act with varying ltOlCO upon the small. reduced end. portions ot the leadin -r blocks or jtfaogineuts ot blocks at each row. and. pret'mahl also, the outer edge oi the terminal limb is corrugated to provide a series ot small projections 1 which are spaced apart correspondingly with and in alternation with the adjacent cutters so as not to obstruct the latter during their reciprocation, yetbear upon and steady the uncut :lront portions ot the reduced match stock. The orerl'uingrinu' limb of each of the remaining sections has cut therein a single median slot ill. which provides two pressure inenihers adapted to exert relatively {greater pressure upon the larger bodies of the blocks which are presented to the cutters.

its a simple and etlieient means to close the slots :21 ot the respective sei'ztions. and thus prevent the accumulation therein of dust and other retuse which would tend to interfere "with the tree independent action at the iutljacent pressure members. I. provide suitable filling: pieces for the slots. In the use o't each. of the terminal sections the. tilliuu' piece con'iprises a u shaped metal strip, the sides 2st of which are entered in the slots from the bottom, and the base or body 525 at the strip is secured. to the intermediate limb. the sides to 'minatiinr in tail pieces 26 which close the spaces between the adjacent nose pieces.

in the case at each ot the limbs of: the re iuainiu sections the lillino; piece couip uw a trip :Bi' having a base which secured to the under side of one of the pair of pressure members when the strip entered in the slot. The strip 2'? similarhto the sides ot the U-sha ;1cd piece. terminates in a tailpiece which closes the space between the been.
