. Fig. is a similar view showing the application of the gauge for setting a lower creasingl member. l I Y I Fig. 8 is van enlarged detail'view of a portiony -of the stock showing the impression formed by the scoring andn creasing devices.

Usually scoring and-creasing machines of the type to which the present invention relates comprise plurality of 'units through j as by set screws 37.to the bar 23. It will be i927. .si-,ritiirai-*195,1104

which the stock is passed to crease 'andscore the same along thedesired parallellines. For

lthe purpose of illustration, only one unit is indicated in the machine shown in the drawings. rllhis machine comprises a bar 23 mounted in fixed position in the machine and a shaft 24 disposed parallel and adjacent to the bar 23.-V Conveniently, and as herein shown, the frame of the creasing and scoring mechanism may include -a pair of parallel side uprights 25 between which a suitable table (not shown) as well as the bar 23 are supported, said upright's earryingsuitable bearings in which 'the-shaft 24 is journalled. Suitable means are also provided for rotating the shaft 24. As shown Vthe shaft 24 is provided with a driving pulley 31 to which power from any suitable source may( be applied through a belt (not shown). l

Separately, detachably, and adjustably' mountedgon the bar 23 lare creasing and scoring devices corresponding in number and arf rangementtoV the scored and creased lines of` the yblanlr.-` Preferably, asV shown, the creasing devices 32 and scoring devices'33 comprise disks lor wheelsrotatably mounted in earri'ers`34 adjustable as fby adjusting screws 35am holders 36 detachably secured seen that the holders 36` with their creasing Vand scoring devices can be applied at willto the bar 23 or removel` therefroin or adjusted therealong transversely of the machine in accordance with therequirements ofthe w'orlr.r i The creasing devices 32 have peripheral rse surfaces shaped to` cooperate with coinple'- .-inentary surfaces on the shaft 24 tocrease or score the stock S asindicated'- at c and s re-V spectively in Fig'. 8. To this end and as most elearly'show'n in Fig,V 7 the creasing wheel or disk 32 is formed with a peripheral groovel which receives a rib V38 on the shaft 24. Each undercut 0roevei4()a in the -sliaft wlierebv' c: i .l

said ringo-r collar may be adjusted along.

`rib 38 is formed on a ring or collar 39 adjustlsaid shaft in accordance with the adjustnient ofA the complementary' creasing wheel on the bar 23. Preferably the ring or collar `is split to facilitate its applicationto and re- -inoval from the shaft, andtheftwo Vsections 'are secured in assembled relation aboutthe shaft by bolts or screws 41.4

. @Ehe-bar 23, whileoccupying Ia opera-g tive position iii the machine, is preferably pivotally mounted therein to turn about a fixedv transverse axis yinto operative or 1noperative position.. As showmsaid bar is yin Fig. l.

(vided.

formed With trunnions 43 suitably jour* nailed in the upiights and is provided With an operating handle .44, whereby it may be readily turned upon said trunnions into the operative position shownin Figs. 3, 4 and 7 or into the inverted orY setting positionY shown The handle 44 cooperates Vwith a fixed segment 45 carried by one of the side uprights 25 and'is provided With apivoted manually operated latch 46 cooperatingwith openings 47 in said segment, whereby the bar may be locked in either position.. When the bar is in operative position, the creasing and scoring devices thereon are broughtinto cooperative relationship With the complementary surfaces on the shaft 24, and when said bar is turned into its inverted position,

said creasing and scoring devices are brought into a position adjacent the top of themachine Where they can be conveniently applied to, removedv from, or adjusted on the barl For the purpose of facilitating the setting of the creasing and scoring devices in their proper relative positions en the bar 23 and shaft k24, the collocating instrument most clearly shown in Figs. l and 2 may be pro- As shown, said instrument comprises fa vbar 43 extending transversely across the -m'achine and carried at its ends by slides 49 7 In accordance With one feature of the in-v vention the co-operating creasing members are provided with points equidistant from or bearing soin-e other definite relationvto the central plane of the effective ci'easii'ig portion thereof so that said central vplanes may be alinedaccurately and readily Without special skill or experience by a gauge. In the `enibodiment ofv the .invention illustrated the radialv face 60 of the creasing diskor Wheel 32 -is spaced from the central plane of the effective creasing portion of said Wheel a( distance equal to or Which bears a definite relation to the distance which the radial face 61 on the collar 39 is spaced from the central plane of the effective creasing portion vof the riby 38 Yon the collar 39.V

A gauge G is provided which is adapted to embrace or fit vover the edge of onel of the It will be seen that the cooperatingcreasing members. In the form illustrated, this gauge coi'nprises two members having faces 62 'and 63 spaced apart to fit over the creasing Wheel -or disk 32 and con.n nected by a portion 64 having a part, such as hair line impression G5, thereon located in a plane having. adefinite predetermined rela-Y tion to one of the faces 62 and 63 when engaging a predetermined surface of the disk 32 so that this line will lie in the central plane of the effective'creasing portion of thedi'sl. In order that they gauge may be placed upon the disk and held securely thereon during the adjusting and setting operationthe gauge is provided with a threaded opening 66 to'` receivea clamping screw 67. In order thatV the central plane of the effective ereasingportion of the rib 38 on the collar 39'may be aline'd With the central planeof the effective creasing portion of the disk 32, one of the faces of the Vgauge is provided with a projection 63 having a face :which is adapted to engage a predetermined point or surface upon the collar 39, herein shown as a radial face 6l, When the gauge is fitted over the edge of the disk 32 to bring the central planes ofthe effective creasing portions of the rib 38 andV disk 32 into a common plane.

Vhen it is desired to adjust or set the cooperating creasing members, the bar 23 is turned to the inverted or inoperative posit-ion shown in Figs. l and 2. The scale is then turned upon its hinge 54 into proximity With the creasing members. The gauge G-isthen fitted over the edge ofone of the creasing members upon the bar 23 With the hair line in the central plane ofthe effective creasing portion thereof. The creasingl member is then adjusted to bring the hair line ata desired point upon the scale. Without changing its relation to the adjusted creasing member, the gauge is then brought to a'position Within the path of adjustment of the creasing member cooperatingl With the adjusted creasing member and thereafter predetermined points or surfaces -of the' gauge and cooperating creasing member are brought-into engagement thereby aligning the central planesY of the effective portions' of the tivol creasing n members. In this manner theV various coopyerating creasing members are adjusted upon the machine relative to each other as desired. V
