This invention relates to the manufacture of book matches and is directed more particularly to apparatus adapted to transport or convey book matches or parts thereof along a predetermined path with intermittent movement. The apparatus is adapted for employment in different stages of the manufacture of book matches and is to be understood as not limited to such employment in any particular stage or stages. Nevertheless, it is particularly usefulfor the intermittent transportation of cover and comb blanks through the successive operations practised upon such parts for the assembly thereof, such, for example, as the folding of the opposite ends of the cover blank over the comb blank or blanks and the subsequent stapling of the cover blank to the comb to complete the assembly. For

the purpose of illustration, therefore,the invention will be described in this particular environment. r

In the assembling of book matches, match book parts are adapted to be fed along a stationary table in' an intermittent manner and this table is provided with one or more longitudinal slots in which is positioned what may be termeda corresponding number of racks mounted for longitudinal reciprocation and adapted at the termini of longitudinal travel to be alternately raised and lowered, so that during forward movement match book assemblies on the table may be engaged and carried forwardly with the rack, the rack thereupon being lowered during retrograde reciprocation to be againraised into cooperative relation with the'match book assemblies at the beginning of the forward stroke. This type of apparatus, generally speaking, is fully explained in Patent No. 1,69%,505 issued December 11th, 1928.

The present invention, however, has to do primarily with more eiiicient mechanism for supporting and operating the rack or racks to which reference has been made in order to minimize the number of operating parts, to insure the smooth running thereof andto obtain marked accuracy in the rectilinear, intermittent feed under consideration. Where long levers and the like are employed, there is always more or less lost motion and whip BOOK MATCH MAKING MACHINES 1930. Serial N0. 467,257.

which tends to render the feed inaccurate and which, at best, requires continual servicing in order to maintain the apparatus operating at a satisfactory degree of efiiciency. purpose of the present invention, therefore, is to minimize the operating connections, dispense with the employment of long-levers and to bring the prime moving devices which act upon the rack or racks into direct cooperation therewith for the purpose of overcoming the objections stated and others and to render the operation of the device smooth, absolutely reliable and practically noiseless.

Features of the invention, other than those specified, will be apparent from the hereinafter detailed description and claims, when read in conjunction with the accompanying drawings.- 7 V V The accompanying drawings illustrate one practical embodiment of the invention, but the construction therein shown is to be under; stood as illustrative, only, and not as defining the limits of the invention.

Figures 1 to hinclusive, are longitudinal sections through apparatus embodying the present invention and showing the parts in various positions incident to their normal operation. I

Figure 5 is a plan view. of the structure shown in Figures lto l.

Figure 6 is a section perspective of such parts. 7 W I 1 Figures 7 and 8 are transverse sections on the'line 7-7 and 88 respectively of Figure 1. V

Referring to the drawings, 1 designates a stationary table along which match books are adapted to be moved. 'As shown in the draw ings this table is provided with two longitudinal parallel slots 2 and operating ineach of these slots is a bar 3. These bars are arranged in parallel relation and are secured together at their lower edges by attaching plates 4: as indicated in the drawings. These attaching plates are secured to the respective bars by screws 5 and are preferably so placed that they may be also utilized as wearing plates. Along the upper edges of the bars 3' are so cured spaced apart teeth 6.- These teeth may have a forced fit with the bars, so as to strad- The dle them and grip the bars with sufficient force to hold the teeth in position, but yet permit of such manual adjustment as may be desirable. Set screws may be utilized to lock the teeth in adjusted positions. The bars 3 with their teeth 6 and the attaching plates 4 constitute collectively a rack. In practice, one of these bars or a plurality of them may be employed in the manner stated and they will of course operate within a corresponding number of slots in the table. Nevertheless for the purpose of illustration, two slots are shown. 1 1 y The rack is positioned to float within the slots 2 and to be supported upon cams 7 and 8 adapted to directly coact with the wearing plates i as illustrated in Figures 1 to 4: and

'2'. These cams 7 and 8 are fixed on shafts 9 and 10 which shafts extend transversely beneath the table and carry bevel pinions 11 which mesh with gears 12 fixed on a counter shaft 13 by which the cams are driven at the same speed. Springs 14 are secured to the underside of the rack and are also secured to suitable anchorages 15 and these springs serve to hold the wearing plates in engagement with the cams 7 and 8.

Also fixed on the shaft 9 is an eccentric 16, the follower 17 of which constitutes the big end of a connecting rod 18. This connecting rod extendsand is secured to a bracket 19 positioned between and secured to the two bars 3 of the rack by means of bolts or rivets 20 as shown in Fig. 8.

It will of course be understood that the shafts 9' and 10 are journalled in suitable bearings carried by the frame of the machine which supports the table 1 and that the anchorages 15 are also mounted on said frame.

y The operation of the apparatus described will now be described in detail. Match books either completely assembled or in different stages of assembly are supported on the table 1 for movement to the right in Figs. 1 to 4. Several such match booksare shown in these figures and are designated 21. The books 21 are-held on thetable 1 by gravity or otherwise,,so as to be susceptible of sliding movement to the right. If it be assumed that the parts are in the position indicated in Fig. 1, it will be noted that the cams are so positioned as to elevate the rack to its uppermost position wherein the teeth will extend above the surface of'the table 1 and project between the'match books 21. The eccentric is illustrated as at the beginning of the stroke. As the shafts rotate clockwise, the cams and eccentric turn through approximately 180 degrees to the position of Figure 2, during whichoperation the high phase of the cams, all partsofwhich are of the same radius, maintain the rack at its upper elevation, wh ilethe eccentric moves the rack forward for; the. full throw of the eccentric on the 1,seo,112

forward stroke. During this operation, the match books 21 are slid along the table a a distance equal to the stroke of the rack. Continued rotation of the shafts 9 and 10 beyond the-position of Fig. 2 brings the low phases of the cams in juxtaposition with the wearing plate 4:, so that the rack is lowered to the position of Figure 3, while the eccentric' proceeds to move the rack on its return stroke and this operation continues until the parts. arrive at theposition of Figure 4. As the partsleave the position of Figure 2 and proceed to the position of Fig. 3, the rack is lowered sufficiently to remove the teeth from cooperative relation with the match books and they are thus left stationary upon the table in theposition to which they'have been advancedby the next preceding operation.

This state of-facts continues as the rack moves rca-rwardly through the position of. Figure 4 beyond which the continued rotation of the shaft brings the parts back to the position of Figure 1, i. e., the cams elevate the rack into cooperative relation with the match books 21 with the rack withdrawn to the beginning of its stroke and prepared to continue to function by a repetition of the operations described. During these several operations, the springs 14: hold the rack firmly to a seat on the cams, while the lateral edges of the slots 2 in the table guide the rack through the I movements described. Thus, while the rack is rectilinearly reciprocated, it is raised and lowered, so as to produce a definite dimension of feed at each forward stroke with an idle return stroke, the match books being thus periodically shifted step by step along the table in the manner described. y The structure is unusually compact and the shifting operation carried out on the books 21 may be very accurately accomplished. The poweris transmitted directly from the cams to the rack and whi 1) in lost motion jar and vibration which. invariably occur when relatively long intermediate connections are employed is notably absent in the structure herein under consideration. The parts are so arranged and constituted that there will be a minimum possibilityof their becoming out of order and the structure is sure to require minimum servicing.

The foregoing detailed description and drawingsset forth the invention in its preferred practical form, but the invention is to be understood as fully commensurate with the appended claims. Having thus fully describedtheinvention,

, what we claim as new and desire to secure by Letters Patentis:

1. In a match making machine, ahorizontal table having av smooth flat upper surface along which a succession of match books is adapted toslide with edgewise rectilinear movement,said table having therein a plurality of longitudinal slots, racks operable in said slots in the table and having spaced apart fingers adapted to extend between successive books on the table, wear plates positioned below the table connecting the several racks together for conjoint movement, shafts extending transversely below the table and carrying thereon cams on which the wear plates bear, means for holding the Wear plates in engagement with the cams, an eccentric on one of said shafts, and a pitman connecting the eccentric to the several racks whereby the rotation of the shafts efiects a raising and lowering of the racks into and out of engagement with the match books and simultaneously cause the operation of the eccentric to reciprocate the racks.

2. In a match making machine, a longitudinally slotted, horizontal table having a smooth fiat upper surface along which a succession of match books is adapted to slide with edgewise rectilinear movement, a plurality of racks operable in the slots in said table and having spaced apart fingers adapted s to extend between successive books on said table, transverse plates securing the racks to one another inspaced apart parallel relation, cams engaging with said plates to support the same, said cams having high and low phases, the former of which when in cooperation with the plates will maintain the racks in elevated cooperative relation with said books, and the latter of which, when in cooperation with the plates, will support the racks in lowered position and out of cooperation with said books, means for driving said cams in timed relation to cause a raising and lowering of the racks, and means for reciprocating said racks, the means for reciprocating the rack and the means for driving the cams being synchronized to produce a forward stroke of the rack while said rack is elevated and to impart a return stroke to the rack when lowered, said fingers being adjustable longitudinally of the rack to regulate the space between successive fingers.

In testimony whereof we have signed the foregoing specification.
