' MACHINE FOR FEEDING AND PRE PARING BlANKS OF PAPER OR ANALOGO US MATERIAL.

SPECIFICATION forming part of Letters Patent N 0. 747,695, dated December 22, 1903 application filed April 27, 1903, Seriall lo. 154,474. (No modeLl To all. whom it; may concern Be it known that I, CHAUNCEY' W. GAY, a" citizen of the United States of America, and a resident of West Springfield, in the county of Ham pden and State of Massachusetts, have invented certain new and useful'Improvements in Machines for Feeding and Preparing Blanks of Paper or Analogous Material,

. of which the following is a full, clear, and exact description. t

This invention relates to improvementsin machines'for feeding and in conjunction'with such feeding otherwise preparing or operating on blanks of paper, cardboard, or analogous sheet material.

The improvements in part. relate to mechanism for feeding in the blanks to secondmentalin preparing the blank having the two-fold function of blank-progressing means and blank-preparing means.

The improvements also relate to an improved mechanism for scoring and cutting the blanks adaptable for ready adjustment to various sizes and styles, enabling the blanks subjected thereto and prepared thereby to be used for various sizes and styles of boxes.

The invention consists in the combinations and arrangements of mechanisms or devices and in the constructions of the devices and parts thereof, all substantially as hereinafter fully described, and set forth in the claims.

The improved machine is illustrated in the accompanying drawings, in which- Figure 1 is substantiallya plan viewof the machine, the carrier, or supporting-cylinder on which final work on the blank fed thereto by the improved mechanism may be performed, being, represented in part in horizontal section on the plane of its axis. Fig. 2 is a central verlical'longltudinal section. Fig. 3 is a representation in side view of the cutting and scoring drum or roll, showing the provisions for the confinementofinterchange- I able blades and spacing-blocks. Figs. 4 and 5 arecross-sections of the drum or roll above mentioned on lines 4 4 and 5 5, respectively.

.Fig. 6 is a perspectivev view of furniture or interchangeable sections to be det'achably carried by thescoring and slitting and grippercarry-ing drum or roll. Fig. 7.is a perspec tive representation of the gripper-carrying portion of one of the drums comprised in the blank-progressing mechanism andof the gripper-carrying portion of the carrier-cylinder. Fig. 8 is a side elevation ofthe same and certain other adjacent parts. 1

Similar characters of reference indicate corresponding parts in all of the views.

In the drawings 20' 21 are suitable side frames in which the several component elements of the machine are supported and which are properly distanced byties 22 23. Secured tothe frames 20 21 .are brackets 24 25, which support a table 26, on which the blanks to be operated upon are properly positioned. The blanks may be fed onto the table 26 from a shelf 27 and between feedrolls 28 29, the former of which constitute in the present instance devices for scoring the blank longitudinally, and are mounted on a shaft 30, continuously rotated in any suitable manner. After the blank has been scored longitudinally on lines of number and spacing, as desired, it will drop onto the table 26,

where it will be positioned for proper presentation to the further machinery.

The means for positioning the blank comprise, preferably, aguide-plate 31, which may be stationary and at the same. time adjustable laterally of the table 26. -Cooperative with the guide-plate 31 are placing, or jogging pins 32, mounted for movement toward and away from the plate 31as, for instance, by a yoke 33-to which reciprocatory movement may be imparted on guide-,rods34: by a link 35, pivotally secured on. the yoke 33 and having its other end adjustably secured to one arm of an angle-lever-36, which is pivoted at 37, and the other arm of which is connected, through a link38, with a lever 39,

secured upon a rock-shaft 40. The blankis devices for the required distance and at the proper time, these means comprising in the form thereof shown a yoke 41, having pins 42 and slidably supported on guide-rods 43, on which said yoke may be reciprocated bya link 44, connected with an arm 45 at any one of a series of adjusting-holes 46, so that the advanced position of the leading blank end may be regulated as desired.

The arm 45 is shown as secured on the rock-shaft 40, above mentioned, and which shaft may be oscillated by an arm 47, connected by a link 48 with a crank-pin 49, secured on a spur-gear 50, journaled on the bracket 25 and rotated by a pinion 51 on a shaft 52.

. Mounted on the shaft 52 is a roller 53, serving as a support for the blank during the operation of the cross-scoring and cutting drum 57, which is cooperative therewith and is mounted on a shaft 54, journaled in the frame, both roller and drum being rotated simultaneously bya gear 56, mounted on the shaft 54, and a like gear on the shaft 52, directly under and in mesh with the said gear 56.

The construction of the cross-scoring and cutting drum is clearly shown in Figs. 3, 4, and 5, in which 57 designates the drum upon which the several scoring and cutting devices are mounted. The peripheral surface of the drum 57 is provided with a plurality of circumferential grooves or T-slots 58, adapted to receive correspondingly-shaped bolts 59 to secure an abutment 60 on the drum in any desired position circumferentially thereof.

Disposed on the outer surface of the drum are scoring-blades 61, which may be positionedrelatively to each other by removable and interchangeable spacing-blocks 62, both blades and blocks having their surfaces concentric with the axis of the drum and preferably held thereon by one or more bolts 63 passing through apertures provided for that purpose in the scoring-blades and spacingblocks. (See Fig. 5.) The bolts of long spring- Wire may be caused to assume the arc form represented in Fig. 5. The drum is provided in this instance with a fixed abutment 64, whereby one end of the bolt 63 may be held, while its other end passes through the movable abutment 60 and may be tightened by a fixed on the drum or roll 57, and carries an arm 69, having a roller 70, adapted for engagement with a cam 71, (see Fig. 8,) preferably stationary and sustained on a suitable supporting part of the machine adjacent the end of the drum and serving to open the grippers, while a spring 72 is operable to close the same.

In Fig. 6 I have illustrated a series of blades in a combination to score as well as cut the blank on predetermined lines, so as to leave the blank-outline in an especial design. The combination here shown consists of the cutting-blades 73, the corner-cutters 74, and the scoring-blades 75,which latter are of somewhat less height than the cutting blades. It will therefore be seen that by substituting cutting-blades of different lengths for those shown at 73 and at the same time replacing the spacing-blocks or furniture with others the distance between the scoringblades may be increased or decreased, and, furthermore, that by replacing the scoringblades with others of different lengths the distance between the cutting-blades may also be varied, thus adapting the scoring-drum for various lengths and widths of blanks and for scoring and cutting or slitting in any arrangement thereon. After the cutting and scoring operation the blank is led toward a carrier or cylinder76, which serves as a support therefor untilit has been finished. Means are provided for seizing and holding the leading end of the blank on the carrier 76, these means comprising gripper-fingers 77, mounted on a shaft 78, having at one end arm 79, the roller of which is adapted to engage a preferably stationary cam 81, whereby the fingers 77 are opened and against the action of a spring 82, which acts on the arm 89 through the medium of the rod 82. The present cylinder 76 is of such size as to have a capacity of two blanks for each rotation, so that the blankgripping fingers are provided in duplicate.

In order to avoid interference with the proper operation of eithergrippers 66 and 77,

the scoring-drum 57 and the carrier 76 are each provided with a series of recesses 83, adjacent to the grippers of the adjacent member, respectively, so that the gripper-fingers may be adjusted on their respective shafts in accordance with different blank widths.

In connection with the construction and action of the drum 57 and carrier 76 it is to be noted that these parts have the longitudinally-extending crescent-shaped depressions or comparatively large grooves or recesses 19 to give space for occupancy of the grippers and the portion of the blank manipulated thereby within the contours of the peripheries of these parts, and the roll 53 is likewise formed reentrant to permit its proper cooperation with the gripper-carrying drum.

The particular method of transferring the blank from the scoring-drum to the carrier is clearly indicated in Figs. 7 and s, in which the roller 80 is substantially free of the opening-cam 81 to permitthe spring 82 to impinge the finger 77 on the leading end of the blank and preparatory to its release from the grippers 66 of the scoring-drum, where? uponthe grippers 66' are operated bythe roller 70 engaging the stationary cam 71 to release the blank, as shown in Fig. 8.

After the blank has been fed into the pair of rolls 52 and 57 and further progressed thereby it will be carried along gripped by the carrier 76, the periphery of which constitutes the blank-supporting surface, and the blank will be subjected to the action of the arrangements for otherwise preparing the samesuch, for instance, as layers of cloth tightly stretched on the supporting-surface of the carrier-cylinder and on one or a plurality of cylinders 111, which latter by having a comparatively forcible pressure against the blank when crowded between such roll and the carrier-cylinder insures both the top and bottom surfaces of the blank partaking of characteristics corresponding to the texture of the surface of the carrier-cylinder and the cooperating cloth-covered cylinder or cylinders 111. Thegears 109 at the ends of the rolls 111, meshing With the large cyl inder-gear 93, cause the proper rotary movements of the rolls 1'11.

Inasmuch as for some character of work itis desirable to quite thoroughly moisten the blank of paper or cardboard, provisions to this end are shown in which the one 53 of the companion rolls instrumental in the progres sion of the blank is utilized as a factor, such roll in Fig. 8 being shown as having a surfacing of absorbent felt 120, its so-surfaced peripheral portion moving in and through the water contained in the receptacle 130, which may be located thereunder,-and by reason of its running contact on the under side of the blank being fed sufficiently moistening the blank to render it the better susceptible to the actions thereon of the devices or mechanism employed in the preparation thereof. 131 represents a wiper-roll in contact on the moisteningrroll. v

The blank brought to and engaged and fur ther conveyed by the carrier-cylinder 76 and subjected to the cooperative action of the cloth-covered companion sets of rolls will in ery of the carrier cylinder when blanks are not being passed through and subject to the actions of the rolls and carrier-cylinder.

After the blank has been carried around on the cylinder 76 and subjected to the action described the carrier will take the same to:

ward the delivery-table126, near which pointthe gripper 77 will be automatically opened to release the blank, which will then be guided and drop onto the table against the adjustable gage 125.

This machine may be utilized as a blank making machine, scoring and cutting the blank, and as a further means for preparing the blank, and it is entirely practicable to work on a continuously-running strip from a supply-roll, in which case the placing of separate blanks one at a time at the feeding-inend portion of the machine would not be necessary, and one of the blanks 61-for instance, the one represented in Figs. 4 and 5, directly above the axis of the roller-drum on which it is carried-could by having a little greater radial extent than the preceding blades in the course of the revolution of the drum serve as a cutting-off means for the successive I blanks repeatedly carried to and subject to the further action of the carrier-cylinder and arrangements in combination-therewith; but the machine is shown as arranged to operate on rectangular blanks of uniform size,

which will be fed by hand or automatically one at a time to the action of the longitudinal scoring- rolls 30 and 29 and thereafter to the adjusting or gaging mechanism, to be then operated on'bythe slitting or crossscoring drum, which grips the blank and takes it to the carrier and cylinder, and the blank may be given an endwise formation by having portions thereof cut out to form flaps or locking-tongues and according to the contour of the blades or ribs provided on the drum;

but the machine may be rendered entirely 4 automatic by permitting the cardboard-stock from the continuous su pply-strip to be guided and fed to and through the initial pair of rolls 28 and ,29, omitting or removing the adjusting device comprising the upstanding studs 42, and a strip from the roll may be run through the machine under proper adaptation of the latter without departing from this invention and may be scored or slitted or be IIO subjected to a plurality of any combination I of devices working thereon and may emerge from the machine in ribbon or continuous form, to be thereafter utilized as convenient.

A peculiarity noticeable in the action of this machine is'that the blanks are fed in a plane substantially coincident with the axis of the carrier-cylinder 76, the arrangement of the paired rolls 53 and 57 relatively-to the v larger cylinder 76, having the recess 19 longitudinally at opposite sides thereon, enabling such approach to the cylinder squarely at the middleof its body and the management of the blank during the time it is being worked upon and the time within which the carrier-cylinder makes one-half of a rotation.
