BOOKING MACHINES Charles F. Wright, Akron, Ohio, assignor to The Diamond Match Company, New York, N. Y., a corporation of Delaware Application October 30, 1937, Serial No. 171,890

4 Claims.

This invention relates to mechanism for folding flexible covers and introducing them in the travelling cover carriers of booking machines and the like, having reference more particularly to match booking machines, such, for example, as disclosed in United States Patent No. 1,042,472, dated October 29, 1912.

The object of my invention is to provide simple and efiicient mechanism whereby the rapid and accurate folding of the covers and the insertion of the folded covers in the links of the carrier can be accomplished.

To this end the invention comprises novel features of construction and combinations of parts which in a preferred embodiment of the invention will be hereinafter described; the scope of the invention being expressed in the appended claims.

In the annexed drawings- Figure 1 is a front elevation of a portion of a match booking machine equipped with cover supplying, folding and inserting mechanism embodying my invention.

Fig. 2 is a transverse vertical section, as on the line 22 of Fig. 1, showing the cover suction head in vertical position adjacent the carrier; the folding and insertingv member being at the limit of its acting or inserting stroke, and the folded cover strip as inserted in the carrier.

Fig. 3 is a similar section showing the suction head in raised position adjacent the cover supply hopper; the folding and inserting member being represented as retracted from the carrier, and the position of the suction head with a cover supported thereby being indicated in dotted lines during its subsequent movement to vertical position.

Fig. 4 is a sectional detail showing the lower portion of the suction head in vertical position adjacent the carrier, and the acting end of the folding and inserting member as co-acting with the complementary folding members to fold a cover preparatory to its insertion in the carrier.

Fig. 5 is a similar view showing the cover as folded and inserted in the carrier.

Referring to the drawings, I designates a portion of the supporting frame including the table II of a match booking machine; I2 designates a power-driven cam shaft which extends longitudinally of the frame and beneath the table, and I3 designates a portion of an endless carrier constituting a form of cover-receiving element which is intermittently actuated by and from the camshaft through suitable gearing. The

carrier which l have selected for illustration comprises an endless chain of pocketed links adapted to travel in a guide trough I4 which is suitably formed on or supported at the rear of the table. The parts just mentioned need no detailed description, as they are disclosed in Patent No. 1,042,472 aforesaid.

The mechanism herein shown as a form of embodiment of my invention is designed to act upon succeeding pairs of covers C in a manner simultaneously to fold the covers of each pair and insert them in folded condition in two spaced links of the carrier. This mechanism embodies two spaced cover folding and inserting elements, each comprising a plate I which is reciprocative transversely of the cover receiving end of the table and in timed relation to the intermittent travel of the carrier. The respective plates I5 are carried by reciprocativeblockslfi, each of which is slidably' fitted in guides IT on the table.

The blocks are pivotally connected by links l8 to a pair of rock-arms I9 rising from a sleeve 20 loose on a stationary shaft 2| located beneath the table. The two arms I9 are connected by a tie rod 22 which is pivotally connected by means of a link 23 with the upper end of a lever 24, whereof the lower end is fulcrumed in a stationary base bracket 25. On the lever 24 is a lateral roll 26 which is operatively fitted in the race of a face cam 2'1 fast on the shaft I2. The contour 3 of the race is such that during a partial rotation of the cam' 21 the blocks I6 and their respective plates I5 are reciprocated toward and from the carrier, and in the remainder of the rotation the blocks and plates are at rest at the limit of 5,

supported by a suitable upstanding bracket 29 1.

on the table, and which hopper is preferably inclined in relation thereto, as shown. Each of the hoppers is of proper size to contain a stack of covers (C), whereof the lowermost cover is sustained at its ends above and in angular relation to the path ofthe adjacent plate [5. The conic points of screws 30 which are threaded in plates on the walls of the hopper afford a simple and eflicient meansfor supporting the lowermost 5 cover, yet permitting it to be bodily withdrawn, flatwise, from the hopper, as will now be described. 'Journaled in thetwo brackets 29 is a hollow rock-shaft 3|, the interior of which is connected at one end by means of a pipe 32 with a suitable 'air exhaust line.

Fixed to the rock-shaft and in communication with the interior thereof are two corresponding suction heads 33 which by actuation of the rock-shaft are together swung in paths between the bottoms of the respective hoppers and the forward side of the carrier 13 in such manner that the lowermostinclined cover in each hopper is bodily withdrawn by suction from the hopper and positioned vertically with the lower or free end of the cover depending in front of and in proximity to a link of the carrier, as indicated by dotted lines in Fig. 4.

As illustrated each of the suction heads 33 comprises a body having at its upper end a hub 34 through which the rock-shaft 3| extends and having also a lower chambered face portion 35, the mouth of which is covered by a perforated plate 36. By actuation of the head this plate is moved flatwise against the opposing cover in the hopper and swung downwardly and rearwardly therefrom. The chamber (3?) of the portion 35 communicates by means of a duct 38 with a port 39 in the hollow shaft 3!, thus providing for: the exhausting of airfrom the suction chamber. The lower end of the body 33 has depending side lugs 40 in and between which is freely mounted a roll 4! which, when the suction head is swung rearward to vertical position, lies adjacent the front of a carrier link and immediately above and parallel with the path of the proximate folding and inserting plate l5. Underlying the path of the acting end of each of the 7 plates I is a similar roll 42 which is mounted in a bracket 43 permanently fastened to the forward side of the guide trough Hi. When the suction head is in its vertical position adjacent the carrier, as seen in Figs. 2, 4 and 5, the two rolls are'in spaced parallel relation, and hence the lower or free end of the coverborne by the head depends in front of the rolls and across the horizontal path of the acting end of the folding and inserting plate l5. Consequently such end in the rearward or acting stroke of the plate 15 impinges against the depending portion of the cover and forces it through the space between the two rolls and into the adjacent link of the carrier, thus transversely folding such portion and inserting it in the carrier link. In this operation the roll 4 l bears upon the cover and maintains it fiatwise upon the associated plate 15. In the forward or return stroke of such plate the suction head is swung forward and upward to position its suction chamber in close relation to the next succeeding lowermost cover in the hQpper preparatory to the transference of the cover to vertical position with its lower end depending adjacent the carrier.

The means herein illustrated for actuating the hollow rock-shaft 3| and the two suction heads 33 comprises an arm 43 fast on one end of the shaft, which arm is pivotally connected by means of a link 64 with the upper end of the longer arm 45 of an angle lever loose on the stationary shaft 2|. The other arm 46 of the lever has a lateral roll 41 which is cperatively fitted in the race of a face cam 48 fast on the power-driven shaft l2; the contour of the race being such in respect to that of the cam 21 that the suction heads are operlimited to the particular exemplifying form thereof herein disclosed, as the mechanism may be modified within the principle of the invention and the scope of the appended claims.

I claim 1. In a match booking machine and the like having a travelling carrier, means for supporting a stack of covers, an oscillatory element for removing each succeeding cover from the stack and positioning it vertically with a free depending end laterally adjacent the carrier, and means for transversely folding the segregated cover and inserting the folded cover in the carrier, said means including a member reciprocative into and from the carrier in a plane intersecting that of the depending end of the cover, and including also a stationary member in spaced parallel relation to the lower portion of said element when the latter is in vertical position, thus providing a folding space between which the said reciprocative member and the opposing cover portion travel in their passage to the carrier.

2. In a match booking machine and the like having a travelling carrier, means for supporting a stack of covers, an oscillatory element for removing each succeeding cover from the stack and positioning it vertically with a free depending end laterally adjacent the carrier, and means for transversely folding the segregated cover and inserting the folded cover in the carrier, said means including a member reciprocative into and from the carrier in a plane intersecting that of the depending end of the cover, and including also parallel folder rolls providing a folder space between which the reciprocative member andv the opposing cover portion travel in thei'r"-'p" age to the carrier, one of said rolls mounted on the oscillatory member and the other roll permanently supported adjacent the carrier.

3. In a match booking machine and the like having a travelling carrier, means for supporting a stack of covers, an oscillatory suction element for removing each succeeding cover from the stack and positioning it vertically with a free depending end laterally adjacent the carrier, and means for transversely folding the segregated cover and inserting the folded cover in the carrier, said means including a member reciprocative into and from the carrier in a plane intersecting that of the depending end of the cover, and including also a stationary member in spaced parallel relation to the lower portion of said element when the latter is in vertical position, thus providing a folding space between which the said reciprocative member and the opposing cover portion travel in their passage to the carrier.

4. In a match booking machine and the like having a travelling carrier, means for supporting a stack of covers, an oscillatory suction element for removing each succeeding cover from the stack and positioning it vertically with a free de pending end laterally adjacent the carrier, and means for transversely folding the segregated cover and inserting the folded cover in the carrier, said means including a member reciprocative into and from the carrier in a plane intersecting that of the depending end of the cover, and including also parallel folder rolls providing a folder space between which the reciprocative member and the opposing cover portion travel in their passage to the carrier, one of said rolls mounted on the oscillatory member and the other roll permanently supported adjacent the carrier.
