Application filed July 1,

My present invention relates to vertical file folding. machines, the invention being more particularly related to an improved tab cutting mechanism especially designed for use in connection with a .vertical file foldin machine of the t pe described and claime in U. S. Letters Pdtent No. 1,574,? 89, granted to me on March 2, 1926, although my present improvements are not confined to that particular type of machine.

One of the main objects of my invention is to provide a simple and eflicient die cutting mechanism for rapidly cutting difierently positioned tabs on sets of vertical file folders; and a further object is to provide a mechanism of this character, so constructed and arranged that the roller means need not be adjusted or changed in order to produce tabs of any desired form or arrangement on the tops of the file folders, this end including a novel construction of supporting and operating means whereby difierent sizes of die cutting wheel means may be employed in conjunction with the i provide a die cutting blade which is adapted,

said roller means, thereby saving the expense oil providing difierent roller means for each change in the form or arrangement of the tabs on a set of file folders. r

Another object is to provide improved die cutting wheel means, so constructed and arranged that the die cutting blade maybe readily removed from the wheel proper, to make provision either for the resharpening or the replacement of the die cutting blade as occasion requires. A further object of my invention is to upon each revolution thereof. to produce in the stock or web sheet a set ofdie out folder tops having tabs so collated or coordinated that when the completed set of folders is filed vertically in a filing cabinet, all of the tops will be visible at a glance.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements ofparts hereinafter described and claimed. v

The invention will be best understood by reference to the accompanying drawin s forming a part of this specification, and 1n which,

The roller 16, as already intimated, comprises a backing comple rotary die cutting wheel.

my invention, it will be seen for the traveling web sheet during the die cutting operations; and to this endsaid roller is provided with a highly temperedsteel surface.

My invention comprehends the provision of rotary cutting wheel means of variousdimensions and adapted interchangeably to be em loyed in cooperation with the backing roliier for producing in the traveling web sheet different sets of die cut folder tops; and with this general object in view, Iprovide a main shaft 18 for carrying the rotary die cutting wheels of different sizes, means being provided for supporting the main shaft 18 for adjustment toward and away from the backing roller in accordance with the particular size of rotary die cutting wheel selected to produce a given set of die out tops in a web sheet, an adjustable transmission means also being provided for effecting the rotation of the main shaft 18 irrespective of its adjusted position.

The referred means for o era-tively and adjustably supporting the s aft 18 comrises bearing blocks 19 through which may he slipped the opposite ends of the shaft 18, said bearing blocks being slidably mounted in vertically extending apertures 20 provided in guide elements 21, said bearing blocks 19 slidably fitting for vertical adjustment upon keys or ridges 22 projecting into the apertures 20 from the guide elements 21. The open top ends of the apertures 20 are closed by caps 23 which are secured as by means of screw bolts 24 upon the top ends of the guide elements. said caps serving as stops for defining the upper terminal adjustments of the bearing blocks. Screw threaded through cross ieces 25, which define the lower ends of the apertures 20, are adjusting screws 26 carrying heads 27, and coiled springs 28 are placed between the heads 27 and the bearing blocks 19. By this arrangement,.'the bearing blocks are both resiliently and adjustably supported in the guide elements. For the support of the guide elements 21, the uprights 14 have proecting arms 29 attached thereto and these arms have vertically extending sleeve-like portions 30 and openings 31 in which said guide elements have sliding fit and rack teeth 32 are provided on one side of the guide elements for engaging with pinions 33 carried by sleeves 34 pinned on shafts 35 rotatably mounted in the sleeve-like portions 30. For turning the pinions 33. I provide hand wheels 36 having hubs 37 secured to the shafts 35 and interlocking with the sleeves 34. Set screws 38, which are tapped through the sleeve-like portions 30, are arranged to engage the guide elements 21 for securing them in the adjusted positions desired. i

The adjustable transmission means whereby to operate the'main shaft 18 many. given positlon of adjustment comprises a sleeve 39 rotatably mounted in a cross piece 40, which connects the uprights 14, and a collar 41 on said sleeve which rests upon an antl-friction device 42 operatively seated in a su table socket 48 in said cross piece 40.

Telesco ing in said sleeve is a shaft 44 having rac teeth 45 in engagement with the inion 46. A sleeve 47, which is mounted in a casin 48, formed with the collar 41, supports t e pinion 46 and is pinned on a shaft 49 carrying a hand wheel 50 whereby the shaft 44 may be adjusted relatively to the sleeve 39 with which it rotates. Pinned to the top end of the shaft 44 is a bevel gear 51 adapted to engage with a suitable bevel gear 52 detachably secured to the main shaft 18. The sleeve 39, at its lower end, carries a bevel gear 53 in mesh with a bevel gear 54 on drivin shaft 55 which is operated from any suitable source of power. The transmission means is therefore adjustable in order that gears as 52 of different sizes may be employed in connection with the main shaft 18, so as to compensate as may be required for the employment of different sizes of rotary die cutting wheels.

In the illustrated embodiment, the rotary die cutting wheel 56 comprises a wheel proper 57 formed with a circumferential flange 58 and provided with radially extending pin receiving slots 55). Surrounding the circumference of the wheel 57 and hav- 60 projecting into the pin receiv- 59 is a rotary cutting blade 61 which is formed at certain interval-spaced positions with laterally offset cutting portions 62, there being countersiuks 63 formed in the flange 58 for receiving said laterally offset cutting portions 62. For securing the blade in its circumferential seat upon the wheel and against the flange 58 thereon, I provide a clam ing ring 64 adapted to tit flatwise upon tie wheel 57 and to overlie the circular blade 61 and suitable bolt means 65 are taken through the clamping ring 64 and wheel 57, said bolt means being equipped with the usual nuts 66 whereby. as shown in Fig. 5, to secure the parts together.

Now, according to an important feature of my improvements,

ing pins mg slots the circular blade 61 is of a circumferential dimension precisely equal to the composite lengths of a set of file folder tops as 67, 68, 69, 70 and 71, to be cut on the traveling web sheet 17: and where the file folder tops as 67 to 71 inclusive are to be provided with collated or coordinated tabs as 67 to 71', respectively, the laterally offset cuttin portions 62 are produced on the circular ilade in such relative positions that upon each revolution of the rotary die cutting wheel, a set of die cut tops 67 to 71 having collated tabs as 67 to 71, respectively, will be produced in the web sheet 17. After the web sheet through the cooperation of the rotary die cutting wheel and backing roller has had the file folder tops die cut thereon, any suitable folding and folder severing means, such as illustrated in my patent above referred to, may be employed for folding the web sheet lengthwise and then severing it along separating lines as 72 to produce vertical file folders 73, as illustrated in Fi 8., Now,'from what has been said, it will be understood, that rotary die cutting Wheels as 61. of dilferent sizes may be applied to the main ting diflerent sets .of file folding tops in the web sheet. For instance, the rotary die cutting wheel may be reduced in size so that upon each revolution it will die out four tile folder tops; or it may be still further reduced in circumferential dimension so that it will cuton each revolution but three file folder tops. Therefore, by providing means for adjustably supporting the main shaft 18 and by providing adjustable transmission means for operating said: shaft, interchangeable rotary die cutting wheels may be employed in connection with said shaft for cutting difierent sets of file tolder tops.

While l have illustrated and described the rotary cutting blade 61 as having the laterally'oilset portion 62 so spaced that the tabs will be formed in collated or coordinated be formed order as illustrated in Fig. 6, where the tabs til toll are shown as formed on the file folder to s at increasing distances from the left hon ends of the succeeding tops comprising the set, the cutting blade may also with the laterally ofi'setccutting portions 62 so positioned that the tabs :24 shown on the die cut top 75 in the set lllustrated in Fig. l are correspondingly positioned on the succeeding tops making up the set. i

For replacing a rotary die cutting wheel and also the ower receivin bevel gear as 52, the main salt is removed from its hearing blocks 19; this operation being accomphshed by first removing the caps 23 and then lifting the bearing blocks it) out of their guide elements 21. From the foregoing description, taken in connection with the accom anying drawings, it will be evident that through the provisions made for employing rotary die cutting wheels of did'erent sizes, di erent sets offile folder tops may be produced in the traveling web sheet without altering or changing the backing roller l6.

While I have illustrated and described the preferred form of construction for carrying my invention into efiect, this is capable of variation and modification without departing from the spirit of the invention. therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come-within the scope of the appended claims.
