Serial No. 292,851.

-Tl1is invention relates to means for facilitating the flClJLlStllleIlt of carbons upon fan fold orcontinuous-bilhng machines. This typeof machine has a set of carbon-holding blades mounted in stepped order upon a carrier, a carbon being clamped upon each blade, the carrier itself being operable. to shift the carbons rearwardly between the plies of a work-web.

. Thecarbon-blades may be detached from the. carrier in order to secure the carbons thereto. It is found diflicult'to square up the carbon on the blade, so that the same may feed properly with the web, and it is troublesome to handle the same, due to the thinness of the paperand to the carbon-coating. v -The carbons must have their front edges aligned after being placed on the machine, which is usually done by tearing off their 'leadingedges by means of the usual front paper-knife onthe fan-fold machine.

To overcome the difficulties in aligning the side and leading edges of the carbons, a feature of the invention provides a separate special table or .jig upon which a pack containing the desired number of carbons may be aligned prior to placing them upon the .ma-

'chine' By means of edge gages the pack may be aligned and squared up with respect tothe carbon-blades in a predetermined manner upon said table. The blades maybe fastened upon the table to. squarely overlie the rear portionofthe gaged carbons at spacedoif distances to allow different predetermined lengths ofcarbons to be attached to their respective carbon-blades, so that the leading carbon-edges will register when the blades are mounted upon the machine.

' Thecarbon-sheets are aligned by means of Ia side edge gageand a leading edge gage,

after which a clamp is moved to effective p0- sition to *hold'the carbon-sheets in position upon thetable until all of them have been attached to their respective carbon-blades. The table atits rear endis provided with holes corresponding in distance to the holes "on the stepped carbon-carrier of the fan-fold machine. c

A carbon-blade with its well-known pivot- 3 ed clamp open is placed over the top carbon and together with the clamped end of the carbon is swung over and placed nearer the bottom of the table, thereby permitting the next carbon-blade to be placed over the second carbon, and located in the following set of holes, when the operation of attaching the carbon may berepeated. In thispreparatory manner each bladeis loaded with the appropriate length of carbon so as to compensate for said stepped arrangement of the carbon-blades on the machine. o

A feature includes the provision of a side edge gage upon said table and ofa displaceable rear edge gage. ;The latter gage, by means of a suitable connection, may be held in operative position at the rear end of the table until the carbon-pack is properly ali ned and trued upon the table with respect to the blades. 'Hereafter said rear edge gage may be displaced or. dropped below the working face of the table so as to clear the Way for v the swingable clamp upon the carbon-blades and for the carbons to be mounted thereon. \Vith the rearedge gage withdrawn, the rear portion of the carbon may be freely manipulated to be folded over the carbon-blade, and the clamp freely swung, as shown.

1 From the foregoing, it will be noted that the present device furnishes the operator with a set of prefectly aligned carbon-sheets which may be quickly and easily prepared by unskilled help. Such reparation will save. the operators time whi e reducing to a minimum the interruption of hercurrent work.

upon pa-rtsof the fan-fold machine to illus 'trate the arrangement of the carbons there- The carbon-aligning device includes a plate or table supported by cylindrical feet 11 atthe front, andibloclis .12 at the rear. A pack of carbons 13 may be positioned upon the table with the aid of a side edge gage 1 1 and a rear edge gage 15. The side edge gage is adjustable, according to the width of the carbons, by means of ordinary screwand-slot connections 16, and carries mounted upon its outer edge a clamp-device 17 which is operative to hold the pack of carbons in gaged positions upon thetable. The clampdevice may be effective to hold the left-hand margin of the pack, and may be the one disclosed in the patent to Thieine 1,617,728. The rear edge gage, for purposes hereinafter to appear, may be raised and lowered between effective and ineitective position. It includes a flat bar 18 terminating at the right-hand end in a'struck-up angular projection or finger-piece 19, by which said gage may be moved sidewardly in either directionthereof and raised or lowered, respectively, due to the presence of an inclined slot 20 at each end of said bar 18, and shouldered screws 21 coasting with the slots and threaded int the rear part of the blocks 12-.

Lateral extensions 22 and 23 of the table 10 furnish the base for attaching the carbonholding blades, and are provided with paired sets of holes 24, in which a well-known carbon-holding blade 25, by means of pins 26 thereon, may be stacked so as to squarely overlie the rear portions of the carbons.

After a pack, including the desired number of carbons, is gaged and clamped down, as shown in Figure 1, an operator may proceed to attach the carbon-blades to the carbon-ends in a manner most clearly shown in Figure 3. Since the pack is securely held in place by the clamp-device 17, the operator now may lower the rear edge gage, .as ll'lCllcated, below theworking face of the table, to clear the way for freely handling the carbon rear ends. Upon the'standai'd carbonblade is pivoted a carbondiolding clamp 1-7. Nhen the rear gage is withdrawn, the clamp 21'' may be swung without obstruction. A left carbon-blade with its clamp open may be placed over the top carbon and attached at one side to the table in the lower set of holes; the top of the carbon is then folded forwardly over the blade and the clamp 27 moved to efiective position to hold the carbon creased upon the blade. The blade is then lifted out of the holes and, together with the clamped end of the carbon, swung over and placed nearer the bottom of the table, thereby permitting the next carbonblade to be placed over the second carbon and attached to the table in the lower right set of holes when the second carbon is folded over the blade and clamped, As now this second blade is lifted from its holes and placed upon the front part of "the table, it permits the operation of attaching the carbons to their respective blades to be repeated according-to the remaining sets of holes, thus affording the desired variation in lengths of the carbons, with the result that the leading carbon edges are properly linedu p and registered after the blades are placed upon the machine. Figure 4 diagrammatically illustrates the :novel arrangement of the blades, and the registering front edges of the carbons 13, omitting, however, for the sake of clearness the Work-web proper. 28 indica es the car on-carriage shown to abut an adjustable rear stop129 upon :usual track- 'rails 30, the carbon to extend over a guidebar 31, around a platen 32 and about .to enter between a usual 'webesevering knife .33 and the platen.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.
