To allan/omet 'may concern.: i

Beit .knoivn thatil. 0i nonA C. THOMP- soN, a citizen of the'i'nited States1 and a resident? of- Wli'ite Plains, .county of .Xi/'estchester, and State or' New York, have 1nvented an Improvement'in llox-lilank Machines, of which the oiiowing description, in connection with the 'accomi'ianying drawings,is a specification, like. characters on the drawings representing;r like parts.

This invention relates to machines for imaking 'box blanks, suchfor example as comprise a'series of sectlons of thin wood'or other suitable material bound together by wires stapled to the'sections. The boX blank is formed in the machine and subsequently folded and assembled with its ends' to forni a complete box in the usual manner.`

The character of the invention may be best understood by reference to the, follovv ing description ofen .illustrative embodiment thereof shown in the'accompanying drawing, wherein:

Referring to the drawing, the illustrative machine there shown comprises frames 1 and 3 (Figs. '2 and 12) for seipporting a carriage on which the box sections are assembled to form a box blank. As shown herein, this'carriage comprises link 'side chains 5 passing around idler sprocketvliecls 7 (Fig. 12) at one'end of the machine and around driven sprocket wheels 9 (Fig. 2) at the opposite end of the machine. said sprocket wheels' being` mounted on shafts journaled in bearings carried by'- said frames llycd Torender the chains adaptable for blank sections of dili'erent assembled lengths, the bearin s of the ider sprocket wheels are adjusta le on their frame toward or from said-driven sprocket wheels. To provide for sections of different widths the sprocket Wheels at one side of the machine may be adjusted relatively'to those at the opposite side 01' the machine in the usual manner.`

Theside chains 5 are composed of links formed to receive the cleats for the sections` Each link comprises side bars 1()a and'l secured to a. base bar 10 by screws or other suitable means. .To position and prevent. the sections-end cleats from sliding along the lihks, spacer hlocksIOi are provided preferably formed to straddlethe link bar 10b and are-securedin various positions', on `said bar 'by set screws `10e according-to the dimensions of the sections and cleats' used.

A The carriage may bodriven in a variety ot waysfor different-purposes. To impart step-hy-step movements to the carriage each movement beingr preferably a distanceorresponding to the s ucebctween staples', the driven s] r0okct Wli'eel shaft. (Fig. 2) i's provided with a 'ratchet wheel 11 engaged by aspx-ing pressed pawl 13 carried 'by a. rocking arm 15 having'one end journaled loosely on said sprocket shaft andjits oppo site end portion connected by a rod 17 with an eccentric strapll on an eccentric 21 festz i opposite side of the machine by a belt pulley 25 (Fig. l) in the usual manner.V

To vary the length of the step feed of the carriage the pawl carrying arm 15 is provided with an elongated slot 27 receiving an adjusting pin 29 in an eye ot the eccentric rod 17 so that by sliding said pin in said slot various distances from the sprocketshaft the throw of the pawl and the feed step of the carriage can be varied.

It is desirable to vary the spacing of the staples at willl and during therunning of the machine. This may be conveniently effected by manually operable means conveniently accessible to the operator for sliding the pin 29 in the elongated slot 27 of the pawl carrying arm 15 for advancing the ratchet Wheel 11 step-b v-step. To this end the pin 29 is connected by a link 29*l to -a lever 29" ulcrumed intermediate its ends on a pin 29c projecting from one of the side frames of the machine. To rock this lever, its upper end is provided with a block 29d Y project-ing from a face thereof and into an arcuate slot 29e of a segment 29 pivoted to the machine frame and having;r a handle 29g whereby the segment may be readily rocked. To fasten the segment indifferent positions of adjustment, the handle is provided, with aspring pressed ratchet tooth 29 co operating with a ratchet 29- fast on the machine frame.

By the vab'ove described construction the handle 29g may be gripped and rocked to various positions of adjustment and in so doingr it will rock the lever 29 and the latter, through the link 29, vwill slide the adjusting pin .29 radially toward or from the fulcrum of the rocking arm 15 and thereby vaxl'y the length of the Step feed.

his is a very advantageous construction since. for example, two different running positions may be usedon some boxes or crates, one position for the top and bottom and the other for the sides whereby a given number` of staples-can be placed in the.top and bottom and a predetermined number of staples can beplaced'in the sides, the spacing of the staples inthe latter being different from that of the top,I and bottom` .Usofstaplcs can be placed at the proper places on the side of crate; that is, in the slats only-'and not in the spaces between, sluts. v This control may also be used to prevent the application of staples at joints between the sides of the box. The handle 29n may be set to a normal running position and may be 'shifted to lengthen the step over a joint and then back to its normal running position.

It is desirable to notl only provide an automatic step-by-step feed of the carriage,

but also at times to manually cont-rol the BEST AVAILABLE copy feed thereof. To this end a ratchet gravity pawl 3l (Fig. 2) is provided carried by an ar-m 33 fast on a stud 85 on the frame l and adapted to be rocked by a log handle 37 j fast on said stud and projecting rearwardly to' a point conveniently accessible to the operative of the machine. During the au tomatic step-by-step advancn of the ratchet wheel the pawl 3l will. Wipe idly over the teeth thereof. When it is desired to actuate said ratchet independently of the other feeds described, the handle 37 may be grasped androcked to impart movement to said ratchet. This will be advantageousfor a variety of purposes. Among others, this handle may be used to control the carriage feed and prevent the'application of staples in the joints between sections. Thismay be done in different Ways, as by prolonging a feed step at the same rate of speed or by increasing,r the speed of feed to produce a greater feed step in a given period of time. Also by the use of this handle the first blank section may be fed to bring the same at a proper position beneath the stapling mechanismto receive the first staple and to feed each successive-section to lts proper position for its first staple.

`used to vary the spacing of the staples in the top4 and bottom from the spacing in the .ed by the machine frame. The pawl 39 is normallyypresscd in. toward the cha-in adjacent thereto by a spring 47, such movement' being limited by a pin '49 on the carrier occupying an elongated eye 5]. in said pawl.

It may also be To reciprocate said pawl carrier in its guides one end thereof is connected by a link 53 (Fig. 4) to a rocking lever 55V fulcrumed between its ends ony a stud on the frame, said lever in turn beine,r connected by a short arm 57 to an eccentric strap 59 on an eccentric (il. fast on the main-shaft 23 referred to.

As stated, to properly space and osition lthe box blank sections on the carnage, the `latter is provided at intervals with ap-` propriate spacer blocks. These blocks have projections extending outwardly from the chains and into the paths of the detector pawls. As a result, when said'pawls travel to the right in Fig. 5 ltheir inclines will Wipe across the ends of said spacer blocks and then spring back of them, so that on opposite travel of said pawls-they will engage the spacer blocks and it moving more rapidly than the latter, will pick up and feed the carriage-independently of its automatic pawl and ratchet step feed; I

To avoid stapling at a joint between ,sections/ the detector actuating means described may be operated to prolong a feed step or it may be arranged to increase the speed of the feed to l'produce a longer feed step in a given period of time; or by maintaining a-uniforrn speed of feed, but prolonging the period during which the feed step continued. y These results can behad by various means, as by driving the detector operating Aecentrics at different speeds or by varying the lengths vof 'the driving connections from the eccentrics to the detector carriers.

The detectors are arranged'relatively to the stapling mechanism so as to cause the ski in the feed'to occur at the proper time wit respect to the operations of' said mechamsm. v

It will be noted that While the pawlf?) may not engage each block l()d at the same point of travel in its motion imparting movement to the left in Fig. 5, it neverthe.

less advances each block to the same position relative to the stapling mechanism, thus automatically positioning each boX sectionA iii predetermined selected staple receivin position. 4

Whi e, as shown herein the spacer blocks for the box blank sections are controlled by the detectors, it will be understood that the control is susceptiblelof considerable modification and that it might be had byv other devices associated with the box blank carrla aving described' the carriage, the automatic feed therefor, the manual control and the automatic mechanism for avoiding stapling at a. joint between sections` l will now describe the means for applying the binding wire to the sections and then describe the means for stitching or forming and ldriving staples to secure said wire to said sections.

The binding Wire may be led from'any suitable source of supply, herein illustrated as a. series of reels 63 (Fig. 2) loosely mounted on a shaft carried by hangers 65 having hooks for,;,removable connection with a rod 67 carried by a frame 69 secured to uprghts 7l of the machine frame l. 'l`o preventl the wire from jumping over the ends of the reels and to retard the unwind ingof the wire from the reels,lthdy may be provided with gravity brake shoes 7 pivotally connected to said reel supportilig rod (i7. The wire is led from the reels down toward the carriage to guide rollers '73 carried by brackets '74 on a horizontal rod 5:3 extending from side to side of the. inachine slghltly above the carriage chains and thence to and beneath rollers 76 carried,

'15" evArLABLE coPY by the stitchers. The leading ends of the wires are suitably secured to the first section and progressive movements of the carriage willcause them to lie across and connect the box blank sections.

To contribute to'the positioning of the sections a's they' are led beneath the stitchers, shoes 75a are provided convenientlyv pivotally connected topand depending fromstaple forming and driving mechanisms which'l will now describe. One of these mechanisms 'is provided for each wire, and being similar, a description of one will suflice for all.

Referring more particularly to Figs. 6 to l1 inclusive, such mechanism comprises lower and upper heads 79 and 8l detachably4 and adjustably mounted on cross-bars 83 and 85, one of which is fixed to the side frames of the machine while the other is carried by blocks 87 .adapted to slide vertically n guide ways 89 in the uprights of the machine side frames. To impart vertical reciprocation to said blocks 87 they are connected b pitmen 91 to eccentric straps .93 of eccent ics 95 fast on the main shaft 23' referred to.

To'con ct the staple stock from the reels 7 7 to the ,lower heads. 79 of the stitcher' mechanism, fuiding and feeding means isY provided carried by an arm of said head and comprises an eye 97 in a reduced end of a screw 99 threaded into a bearing block 101 to be. referred to. The wire is led from said eye between feed .rolls 108 and 105, the former being splined to a shaft 107 `our naled in hearings in said arm. said sha ln*-v ing driven step-by-step as more fully here inafter described'.
