4 Claims.

This invention relates to machines for making book matches, having reference more especially to a machine of the type described in Letters Patent of the United States No. 1,042,472, dated October 29, 1912.

The machine referred to includes a horizontally reciprocating plunger by means of which relatively long strips of matches are pushed toward a cover carrier with their margins positioned beneath vertically reciprocating cutters operative to sever the strips into match cards of suitable length for association with complementary covers in the carrier. The match cards are pushed into the adjacent covers by means of a setting plunger which during the upward or idle stroke of the cutters is reciprocative toward and from the carrier, by means of cam actuated lever and link connections. In the event of the breakage during the setting stroke of the plunger of any of the pins included in such connections the cutters impinge against and are damaged by the opposing plunger, thus necessitating the prolonged stoppage of the machine for the repair or the renewal of the cutters.

' The object of my invention is the provision of simple and efficient means whereby the setting plunger is at once automatically retracted from the path of the cutters upon the break-' age of a pin or pins of the connections mentioned, which means in a preferred form will be hereinafter described and the scope of the invention then be expressed in the appended claims.

In the drawings Figure 1 is a transverse vertical section of a portion of a book-match machine embodying my invention showing the relative positions of the mechanisms when the setting plunger is in its retracted position after the match card or cards have been pushed into a cover borne by the carrier.

Fig. 2 is a view similar in part to Fig. 1, but with the plunger in its setting position.

Fig. 3 is a perspective view showing the strip and card setting plungers, the cutters and the actuating mechanism for said plungers and cutters, together with the safety devices whereby the setting plunger is automatically retracted upon the breakage of a pin or pins of the cam actuated lever and link connections.

Fig. 4 is a detail of the card-setting plunger and the adjacent end of the retracting lever therefor.

Referring to the drawings, 10 designates a suitable supporting frame, including a table 11 upon and along which is guided the upper run of an intermittently movable endless carrier constituted by a chain of links 12 whereof each is constructed to receive and support a matchbook cover, as 13, and a match card or cards, as 14.

The chain is intermittently driven by suitable mechanism comprising in the present instance, a gear wheel 15 in mesh with rack teeth on the links. The stud shaft of the gear wheel bears a pinion 16 in mesh with the gear face of a pin wheel 17 on a lower stud shaft 18, the pins of which latter wheel co-act with a suitable cam 19 on the main shaft 20 of the machine.

A plunger 21, which is guided on a foward extension 22 of the table, is connected at its respective ends, by means of links 23, With two arms 24 loosely mounted on a shaft 25 fixed in brackets 26 depending from the table. One of the arms is connected by means of a link 27 with a rock-arm 28 which is loosely mounted on the drive shaft 20. On this arm is a roll 29 which engages the race of a face cam 30 on a longitudinal shaft 31 beneath the table. This shaft 31 is driven from the shaft 20 through coacting gear wheels in the usual manner. The plunger 21 is held yieldingly in its rearward position by means of a spring 32 which is secured to one of the arms 24 and to the table 11; and the contour of the cam is such that at the proper interval .the plunger 21 is retracted thereby.

' A cover plate 33,'constituting a supplemental table upon which the match strips, S, are deposited overhangs the path of the plunger 21, in spaced relation to the carrier, so that when this plunger is rearward match strips can be placed flatwise thereon from the table 33. This done, when the plunger 21 travels beneath such table 33 and away from the match strips imposed on the plunger, the strips fall upon the main table 11, whereupon in the next succeeding active strokebf tli'e plunger 21, the opposing strips are pushed toward the carrier with their margins positioned below a pair of spaced cutters 34 depending from a vertically reciprocating head 35.

The cutters are constructed and operated to sever the strips into match cards, which cards during the upward or idle stroke of the cutters are pushed into covers 13 in alignment there with in the carrier by means of a supplemental plunger 36 reciprocative transversely of the main table in a path intersecting that of the cutters. The card setting plunger 36 is fastened to a slide plate 37 which is mounted within the feedtable and is connected through a link 38 with the upper arm of a lever 39 loosely mounted on the shaft 25. The lower arm of the lever 39 is connected by means of a link 40 with a rockarm 41 pivoted on a bracket 42 on the base 43 of the supporting frame. On this rock-arm is a roll 44- Which is fitted in the race 45 of .a face cam i6 on the main shaft 20, the contour of the cam race being such as to effect the reciprocation of the card setting plunger 36 in timed relation to the cutters.

The match strips when in rearward position upon the main table 11 are advanced at intervals longitudinally of the table and beneath the cutting mechanism preparatory to the cutting of succeeding cards from the strips, all as fully set forth and described in Patent No. 1,042,472 aforesaid.

According to my present invention, I provide safety means which positively retract the slide plate 37 to withdraw the setting plunger 36 from the active path of the cutters in the event of the breakage of any of the pins included in the operating connections between the cam 4.6 and the slide plate, that is the pins of the lever 39, link 38, rock-arm ii and link 40, or any of them.

This safety means preferably comprises a vertically disposed lever loose on the shaft 31 which carries the cam 30. The upper arm 47 of the lever projects through a slot 48 in the table 11 in the path of the plunger end or" the slide 3'7, and the lower arm 49 or the lever depends adjacent the cam race 50 of a face cam 460 fast on the main shaft. This arm is provided with a roll 51 which is operatively fitted in the cam race and hence the arm is operated independently of the card-setting plunger. The contour of the race 50 of the cam 46 is such in relation to the race 45 of the cam 4160 that the safety lever and the lever 39 are simultaneously oscillated in the same direction during the operation of the machine, the strokes of the safety lever being somewhat less than those of the lever 39. Hence during the normal operation of the slide 37 and the setting plunger 36 the upper arm 47 of the safety lever swings back and forth without impinging against the slide, but in the event of the breakage of any of the pins of the operating connections between the slide and the cam 46 the lever arm 47 bears against the abutment surface afforded by the opposing end of the slide, thereby forcibly retracting the slide sufficiently to withdraw the setting plunger 36 from the active path of the cutters.

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

I claim 1. In a book-match machine, the combination with match-strip cutting and match-card seting elements movable in intersecting paths in timed relation to each other, and means including connections for operating the setting element, said setting element having an abutment portion, or a member projecting into the path traversed by the abutment portion, and means for independently reciprocating said member in the same direction as the setting element.

2. In a book-match machine, the combination with match-strip cutting and match-card setting elements movable in intersecting paths in timed relation to each other, and means including connections for operating the setting element,

said setting element having an abutment portion, of an oscillatory arm projecting into the path traversed by the abutment portion, and means for independently oscillating said arm in timed relation to the setting element.

3. In a book-match machine, the combination with match-strip cutting and match-card setting elements movable in intersecting paths in timed relation to each other, and means including connections for operating the setting element, said its setting element having an abutment portion, of w a lever having an upstanding arm projecting into the path traversed by the abutment portion, and means for independently oscillating said lever to move the said arm in timed relation to the setting element.

In a book-match machine, the combination With match-strip cutting and match-card setting elements movable in intersecting paths in timed relation to each other, and means comprising a cam and lever-and-link connections for operating the setting element, said setting element having an abutment portion, of a lever having an arm. projecting into the path traversed by the abutment portion, and a cam coacting with the other arm of the lever to oscillate said lever independently 01 and in timed relation to the setting element.
