BEVERLEY residing` at Coventry, Englandyhave invented certain new and useful Improvements: in@ Infolding-Machines, of which kthe following f isa specication,

- In machines for lfolding collar. cufl"` `and like blanks, it isfrequentlyjdesired togalter -thefsequencefin whicli'the edges are folded, ,r i thus, it is sometimesdesired to fold the sides first, and the ends last,orI it may be desired.

' to fold one or other of the sidesfrst then l vfoldf the-ends` and thengfold the other side.` to 'get rvarious forms The *purpose of this is of lock corners.

y Accordingto the present invention the op?, erating membersfor the side and end folders f are all adjustable andthe-adjusting mechanism 1 is operatedzyfrom4 a5' common'- member which may-ehe moved into 'various set vposi-v tions to adjust one or more of `thebperati'ng members and leave `the others undisturbed.

able foldersc, which are mounted in carriers b and the presser plate which is guided and -lsupportedfin the frame a. The folders` yc, are shown in Fig.' 6, moved into their fold-- ing position, this bythe centrally pivoted levers 7, carrying at movement being effected their lower ends rollers g, which engagewith cams 54 54 and v56,56to move the folders at the desired timesuand in the desiredse` quenceV as described @more fully hereafter The present invention is more specifically tion ofthe folders sothat they may be moved 1n' vvariable sequence.

The flatblanlA, is first'cupped by means of dies e, lcarried byfeet f, fixed in'movable die head it 7L, thedielheadis swung around plates g, Vfixed bybolts c', inthe movable die head parts lult. `The die head 71.-, L, is'composed of two `parts held apart by "springs fw,

and guided on boltsu,"Fig. l. The conapplicati'on Serial No.' 694,243. y y Y,

The diehead 7L fais-moved in the curved path Y, by meansof the following mecha` `nism. lOn acamor disk 19, mounted on theA operating shaft s, .there-is provided ya roller F18, which ftsinto pivoted at 16. To the short end of the lever aslot 17, on a lever" l5,

means for timing the opera-` Tris rari-:Nr OFFICE. i

struction ofythismovable and adjustable die d. l l head ismore fullyvdescribed in aco-pending l `15,thereis pivoted at 14, a rod-12. About `midwayiirthe length of the-rod 12, thereis mounted a roller l1, which is guided inal curved slot 10, on a fixed bracket `9. The upper end of the-lever 12, is expanded to form a bearing for the' swivel 13, for the die head it' L' By from the Vposition shownin Fig." l, tothat showny inFig. 6. This is effected by the' i means of` a .pin 7, carried .by the die head 7L i, the die headis swung aroundy pin 7, traveling in the'curved groove 8',

formed onthey upper part` o f the bracket 9. The die-head z, z,'.pass esoverftwo end col-i `umns @,farranged atfe'achxlside of the ma?L i chine. These l end columns 'are i supported in `an 'inclined posltionlina fixed; sleeve Q ,and

carry at their lower ends (see Figs. l, and 3) arms 3, on which'are inounteclrollerfs'4. `The f roller 4, engages with the face came, to rotate thestandards e, at required times.` v,The

rotation of the standards a, causes the die head parts/zzf, to come together or expand for the purpose which i is more fullyfex-` plained hereafter;y Below the y folders c, o

Fig. 6, thereis mounted a hot presser. plate d, this presser plate rests onsprings n, and has panded position shown in Figs. vl andl 6.; The folders c, arethen drawn apart farl enough to 'freely admit the expanded: dies e.' The dies e, press the blank A on to thel j thelfolders c. Immediatelythe yolies e, pass'y 'I a pin c, proj 'e'cting downwardly tore'st" on :an

arm pivoted at 79, and carrying a roller Z. r)lie roller Z, rest-s on a cam m.

shown in Fig. l, along the pathshown by the dotted line Y on, tothe'guides or col umns e. The dies e, are then in the exe hot presserplate d, and'thereby pass below below the folders c, theseffolders are moved into the positions shown in Fig. 6, inra defi` nite sequence which maybe ifaried asre` uired. From this position until thel roller g l ,starts to rise at the point ILthe die heads l. lz', 7L, are brought 'together bythe rotation of the columns e, and the die heads alsostart to move upwardly Vfrom the table. In order to prevent the movement of thedies e, from scraping orv disturbing the blank A, ay pin: 2 0 (sec F igs. l and 3) carried by thedief head comes to bear on a spring 21a contained in a recess 21. This happens when the die v head is 'moving into its lowermost position' solthat the weight of the die head does not i fall on the blank, but` is taken up byl the spring 21'. When the point II passes un- I der'th'e roller Z, the hot pressertable cZ, is

moved upwardly to press the blank. From the. points II to IH, the blank is pressed and at the pointIII, the presser plate eZ, re l. ced'es a shortdistance for the blank wheres upon the folders c, are withdrawnurl Atthe point IV, the presser plate (Z, gets a rapid idrop whereby the folded blank falls fromv the table. y x

Having described the general operation of the machine, l .shall now proceed to deal with the novel features according to this" inj vention. Thesenovel features referto the timing mechanism of the side foldersc c,

and the end folders-22.

Referring to Fig. 5, it willbe seen thatv the blank A, shownas-.a-v collar blank, has to f be'ffolded along the vfour edges,A,A%y A3,

At'. If various .kinds of lock corners are desired, the ledges have tobe folded in a' dif-V ferent sequence, for instance, the side A- may be folded iirst,whereupon the 4ends A3, A4, may beffolded and then thexside A2,'v may Abe'folded.` The operation might beE reversed that is to say, the sideA2, might be folded first, 'and 'then the ends Asa-nd A4,]

and lastly -the side A". A third alternative "l would betofold the sides A and A2 simultaneously and first, and theendsv A3 and A4,!

f ,effect one orothe'r offrthesequences described last,- or 5a fourth'l alternative ispo'ssible movement.

A and A2, simulta neously` and last. According to the present invention, means are. provided lfor securing any one of these alternative methods merely by operating a singlesetting member and this in spite fof. the fact thattheside folders c, and the end folders 22, move in transverse paths. l

"The sets ofoperating cams 54, 54 and 56, 56 for the side folders are in pairs and `are. all mounted on a common shaft '8, The pair vof cams 54,` 54 are the early and late cams respectively for the lower folderonthe left ,hand sidein Fig. 6, that is to the front of the operating shaft s, while the cams 56, 56 are the early and late cams for the upper folder on the'right hand side in Fig.` 6, that is tothe rear of vthe operating shaft s. The

dles 56, whichfare onop'posite sides ofthe folding the ends'A3 and Affrs'tand the sides i rollers Q, are Vslidab'ly mounted on their spinilf.

shaft s, so asto :nove the folders c, toward A andl away from one another. Each slidable f roller isthus located to 'co-actfwith `.either cam of one pair o'r set. As seen Figs. 3 and 4, the rollers gk are grooved, so asto leave two pr'ojectingpa-rts between which a Vshifting rod may engage, F The roller g, for the rleft hand side yfolderin Fig. 6, is formed of twofrol-ler parts 53,betweenwhich engages ani" operating bar 5l, which is adaptedto slide the roller g-along its 'spindle 56a, so

asto bring one or other ofthe roller parts `53 into-'engagement withthe cam 54 `or 54?.

The vroller g for, the righf'hand-` side folder' in Fig. 6 is'composed` of-'two rollers 5 5, and

forked and thefree space between the armsin a similar manner is caused bytheoperat-V ing bar 52 to slidealong its "spindle 56a, to bring oneor the Otherb-ftheroller parts 55 vinto' engagement: withthe `cam 56 01H56.

lThe arms 71,' carrying.the-'spindles156@ are V105 is `su'iiicient to allow of the necessaryv'sliding A The bars 5l,4 and 52 w'hiclrengagebetween the roller p artsf53, 53, and 55, 55,are car` .riedfbyf-connecting links or) tie :rods 49 and- -50.` These tie rods Vor'connecting li-nks49,`

50,v are arranged; at each side ofthe machine and are movable by means ofplns 4'`an'd 48, carried on disks 431 and 44. "Thedisks 43 and 44, are supported on transverseshafts 4l, at each end'of the machine. IThe trans- `seen z `more i V clearly inl Figs.V lr 2.1'- This timing shaft is operable byfmeans of a hand' :verse shaft 41, which might be called va timing sha ft, at the right' handend 'in Fig. 4, is'k prolonged yto i the front ,off thel rm'achine* as 41C, andbringingthe handle 41a, around'to a f xedistop: 41d, therequired adjustment toi aber@ with referencesltotheflig. is; ef-` fected. .The handle 4l,j-mayitakeup foun successive positions corresponding to the'. `four positions ofthe timing-` gearshown diag; granimatically.i1IfFi,g1;.=5.` These four posiltions are shown eonseeutivelyzin Fig. `5, in
