To all whom it may concern:

Be it known that l, HENRY A. RUDD, a citizen of the United States, and resident of Barberton, in the county of Summit and State of Uhio, have invented certain new and useful Improvements in Machines for Making CardMatches, of which the following is a specification.

This invention relates to machines for making card matches composed of a series of matches and a common marginal portion to which the splints are frangibly connected at one end. A machine for this purpose is illustrated in Patent No. 636,170, dated October 31. 1899, by reference to which it will be seen that mechanism is provided whereby stock is drawn from a cutting devices by means of which successive match cards are partially formed, each card having alternate splints ,staggered and cut from the stock. The marginal part of the card is advanced to and placed in an endless carrier and the series of attached splints are then separated from the stock during the splint-forming operation on a succeeding card portion of the stock, and. so on. The carrier, with the match cards thus inserted therein in spaced relation to each other, transports the cards through the match-making path, including means for applying composition to the free ends of the splints, and

thence to a discharge station where the com- I plete card matches are successively removed from the carrier.

The splint-cutting devices employed in the said machine comprise complementary upper and lower bar dies, the bars of the upper or male die being reciprocable into the alternate spaces of the lower die. Paper stock is intermittently advanced from a suitable roll to and between the dies by means of feed-rolls, the dies thus cooperating to incise the stock into longitudinally-extending splint portions, whereof transversely cut at one end and deflected into the spaces of the lower die, while the other portions are supported upon the tops of the bars of the lower die so as to remain connected at both ends with the body of the strip. With the soft paper stock which is employed in the manufacture of match cards, the under surfaces of the depressed splints are frequently bowed by the lateral divisional stresses thereon during the cutting and depressing operation, and in conseroll and fed to splint.

alternate portions are quence the fibers of such surfaces are rup- I tu'red and distorted weakened.

To overcome this defect is the object of my invention; and to that end i provide in advance of the splint-cutting dies, means whereby the match-stock is progressively compressed in parallelpaths in longitudinal alinement with the tops of the bars of the lower die. as will be hereinafter described and claimed.

in the drawings- Figure l is a side elevation, partly in section, of a portion of a card-match making machine embodying a preferred form of my invention. "Fig. 2 is a longitudinal vertical section through the feed-rolls and the splint-cutting mechanism, showing the card stock as advanced preparatory to the descent of the upper cutter die.

Fig. 3 is an enlarged sectional elevation of portions of the upper and lower feed-rolls, showing the stock therebetween.

Fig. is a sectional elevation of portions of the upper and lower dies in cutting position, showing the splints as cut from stock which has been acted upon by the said feedrolls.

Fig. 5 is a view of a portion of a matchcard as produced from the said stock.

Fig. 6 is a View similar to Fig. 4, but showing the defective condition of the un dersurfaces of lower or staggered splints as heretofore produced.

Fig. 7 is a view of a portion of a matchcard having the defective splints indicated in Fig. 6.

Referring to the drawings, 10, 11 designate a pair of feed-rolls by means of which paper stock, 12, suitable for card matches is intermittently advanced between the upper and lower bar dies 13, 14., respectively, of the splint-cutting mechanism. The lower die isstationary, and the upper die is carried by a vertically-reciprocative head 1 5 by means of which the bars of theupper die are reciprocated into and from the spaces between adjacent bars of the lower die in such a manner. that the stock is severed lengthwise in parallel lines throughout its and the splints are width to produce a row of splints havthe stock and deflected belowthe others, or

a staggered.

The vertically reciprocative head bearsa cutter 17 which is so located in relation to the dies as to act upon the stock along the outer edge of the marginal portion of the card length as the stock is advanced to and beyond the dies by.tlie feed-rolls, such cutter thus severing from the body of the stock the ends of the upper series of splints which are attached thereto.

In each feed movement of the stock, ands before the action of the dies and the cutter 17 thereon, the marginal portion of the lead ing card is inserted into an endless carrier 18; whereupon the upper die descends and the cutter 17 severs the match card transversely of the stock. The carrier is intermittently movable in a path at right angles to that of the stock so as to present appropriately spaced card-receiving portions to the successive cards.

With the exception of the feed-rolls the parts above, referred to are or may be similar in general construction and operation to the corresponding parts of the machine set' out in Patent No. 636,170 aforesaid.

In pursuance of my invention in its preferred form, the upper roll 10 comprises a plane pressure roll which is journaled at its ends in slide boxes 19 which are fitted in standards 20 on the main frame 21, and are i maintained yieldingly depressed by suitable springs 22 in the usual manner. The lower roll 11 is journaled in fixed bearings in the standards 20 and is provided with alternating circumferential grooves and ribs 23, 24', respectively, each of which is equal in width to a match-card splint. The lower peripheral portions of the ribs are in alinement with the respective upper or cutting surfaces of the bars 14 of the lower die. When the lower roll is intermittently rotated the stock is advanced to and between the dies by the co-action of the ribs ofsuch roll-and theperiphery of the upper pressure roll, which ribs thus act to iron and depress the under-surface of the stock in spaced parallel paths, as indicated at 25 in Fig. 3. The thus compressed portions of the stock are advanced to, and upon the tops of the bars of the lower die while the intervening uncompressed portions {26 of the stock pass to and bridge the spaces between adjacent bars 14, and hence in the descentof the bars 13 of the upper die upon such uncompressed portions and into the underlying-spaces, an effective longitudinal I depression and severance of the unsupported splints is insured without unduly straining or distorting the fibers on the under-surfaces of the deflected splints.

In Figsh l and 5 are illustrated deflected or staggered? splints having uniform under surfaces as produced by a machine embod ing' the roll construction above de scri ed; and in Figs. Sand 7 are indicated deflected or staggered splints having the ruptured undersurfaces (as) which result In the present instance I have illustrated one of the journals of the roll as equipped with a ratchet wheel 27 with which coacts a dog'28 on a rotatable disk 29 that is operated by a suitable connecting rod 30.

It is to be understood that my mvention is not limited to the specific construction herein disclosed, as the mechanism may be modified within the principle of the invention and the scope of the appended claims.
