MACHINE FOR CREASING CARD OR OTHER BOAR-D FOR BOX-MAKING.

Specification of Letters Patent.

Patented Feb. 2, 1915.

Application filed June 1, 1914. Serial No. 842,048.

To all whom it may concern:

Be it known that I, LEWIS A, MAYALL, a citizen of the United States, residing at the city of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Machines for Creasing Card or other Board for Box-Making, of which the following is a specification.

My invention has relation to a machine to automatically by a sequence of operations upon a sheet of card or other board form creasings for being then bent into a unitstructure; and in such connection my said invention relates to the constructive arrangement of the different mechanisms in such a machine for the defined purpose.

Hitherto it has been the general practised method in the making of creased sectional sheets to become box-like structures to first crease one side of the sheet or board, then to shift the sheet or board, to crease the opposite side and then to perform the same action in respect to the ereasings of the ends; but according to my present invention the entire operations of forming creases in the ends and sides of the sheet or board are conducted automatically in the machine by a sequence of following operations performed upon the sheet or board without change of direction of the travel of the board in respect to its plane' of travel through the machine, that is, the sheet or board is fed into the .machine at one end and turned out at the other end creased on two ends and sides, without manual handling during its momentary travel through the machine to complete the creased sectional structure ready for being formed or bent into the desired shape or configuration for use, as a unit section .of a package holder or container.

My invention consists of a machine such as hereinafter more fully described and claimed.

The nature and scope of my present invention will be more fully understood from. the following description taken in connection with the accompanying drawings forming part hereof, in which Figure 1, is a longitudinal side elevation of an automatic machine of my invention, found practically efficient and embodying the essential main features of my said invention. Fig. 2, is a top or plan View of the product of said defined mode, showing how the board is creased first in one end and then in the opposite end, and then by a sequence of following operations in two sides; this view showing also by the arrows how the sheet or board passes automatically through the machine to be acted upon through said sequence of following operatlons upon the said board, for creasing the same, without the machine shifting or changing its plane of momentary travel to complete such creasings thereof, until droppmg from the machine ready Without further manipulation to be bent up along the creasings as shown, into an oblong boxlike unit section to provide ultimately with a similar sectional unit a package holder or container. Fig. 3, is an enlarged detail view in broken sectional elevation of the. stopoperating mechanism locatcd at the rear of the machine, to posit on received board during the formation of the side creases therein. Fig. 4, is a longitudinal central section View of the machine, parts thereof-in this View, being shown in elevation. Fi gs. 5 and 5, are broken sectional plan views of the machine, partly in section, to disclose re spectively detail arrangements of several diflerent mechanisms of the mach ne. 6, is a front e-levational view of the main operating mechanism of the said machine. Fig. 7 represents in section and in elevation the constrrctive arrangement of the plunger creasing devices of the machine. Fig. 8, is an enlarged view of one,-of the plunger creasing devices, showing the character of the creasings of the board by such devices,

shown in action on the board and the par-.

ticular character of creasing at corners in particular, for permitting of the subsequent free bending of the body into required shape, without breaking the fibersl'of the said corners in the bending of the said board. Fig. 9, is a side elevation of the character or shape of creasings finally derived and in manipulating thereafter it will readily yield to any bending along the line of such creasings, without breaking the fibers of the board in order to assume ultimately the form or shape of the unit section of a holder or container required which if otherwise, would appreciably weaken the Fig.

creased structure at such points in assuming thereof and a and a its final shape or form. Fig. 10. is anenlarged detailed elevation and section of the mechanism to permit of the release oftbe board so as to be fed to receive in sequence therein the respective end creases. V Fig. 11, is a view in sectional ferrediarrangement of one of the series of guide-rolls of the machine for guiding the.

board in its travel throughthe machine to be subjected to the series in sequence of aforesaid following operations; and Figs. 12, 13 and 14, are respectively, enlarged sec tional elevations of certain stop-devices 1 and 4. The feed table is provided with an These creasers are as shown in Fig. 5, for

adjustable guide a board to be fed positioning the sheet or unto the machine.

The paper being thus positioned as above, is fed crosswise of the table a, against stops a and (1, located in brackets a and a, carried by the creasers C and C The paper is fed under guides a, Fig. 5, into contact with revolving feed rolls a, journaled to a crossshaft a, positivelv driven by a gear-means to be presently fully explained. On rockshafts b, at the front andrear of the machine are secured pressure-rolls b, for pressing the sheet or board against the rolls a,

feed the sheet or board forward stops o and a. when the said sheet or board is released by the stops (2 and a, to bring the said sheetor board into a true alining position to be acted upon by following operations of creasers C and C located on both sides of the center line of the machineand consist of male and female members 0 and 0 The male member is provided with a T-shaped bar 0 the leg of which is recessed to receive a coiled spring 0 bearing against a T-shaped disk 0*, carried in suitable guides c", which latter are bolted to the leg of the T-har 0 as clearly shown in Fig. 7. The female member 0, consists of a channelfbar 0, in which is mounted an anvil a", supported in position by means of coiled springs a and 0*,forming as so arranged a. cushion for said anvil. The plunger 0 of so as to against the female member is journaled in the anvil a",

and bears against a coiled spring a, mounted in the base portion of the channel bar 0, as clearly shown in detail in Fig. 7. It will be understood that the plunger 0 is afforded a vertical movement independent of the spring controlled cushioning movement of the anvil c", for the purpose of enabling the male die to effect a clean crease elevation of the prefully illustrated in Figs. 8 and 9.

aided by the female die, without destroying the fibers about the corners of the sheet or tion by the independent action of the anvil spring cushioning the sheet or board, whilethe two dies are in pressure contact with the respective surfaces-of the sheet or board to form the required crease of the character as above explained, examples of which are I I he male dies of the respective creasers C and C are carried by cross-bars 0 and a,

slidable in guides 0 and 0 provided in the standard A. These cross-bars by ball hearing connections tries 0 carried by a'driven cross-shaft 0", journaled in the upper part of the standard A. The shaft 0, is operated by a gearwheel 0 meshing with an idler gear 0 and it in turn meshes with a gear at, mounted ona driven shaft d extending across the machine andjournaled to the standard A On the shaft (1 are mounted a series of eccentrics d operating plungers (1 which by means of ball bearing connections d support the cross-bar cl, from which projects the male member d, of the side creaser D. The female member d, thereof, is mounted in the standard A but in other respects structurally is the same as the creasers C and C hereinbefore fully described. After the sheet or board C", has been released from the stops a and a, it is pressed in traveling over the feed rollers a and 0. by the pressure rollers b until the sheet or board reaches the stops (1 and a. The shiftable guide a in the meantime having been moved cross-wise of the machine by a roller a, carried by the cross-bar 0 so that when the end of the sheet or board has reached a position to be acted upon by the creasers C and C, it will at that moment be in a true alining position to the vertically descending male members 0, of the said creasers to be acted upon thereby, to

p 0", are connected with plungers c, operated by a series of ecceninsure a well defined crease in the sheet or board C .The creasers C and C descend alternately to provide by following operations the end creases 0 and (2 in the sheet or board C as clearly shown in Fig. 2. The stops a and a", now release the sheet or board C and it is carried forward by the revolving rolls a and a", until reaching the stops (I and a, when the side creaser D, descends upon the sheet or board C to first form a crease in one side a, Fig. 2, and this creaser D, rises to allow the sheet or board C to be fed forward until reaching the stops 0"" and 0", whenv the said creaser D, again descends to form the other side crease a, Fig. 2, in the said sheet or board.

The. stops a. and a, move up and down in the guide-ways a and a", providedin one side of the female members of the end creasers C and 'C, as clearly shown in Figs. and 10. Motion is imparted to these stops as well as the stops a and a, by

means of rock-shaftsa, journaled in bear= ings (1 and (1, carried by brackets a, ex-

tending from the guide-ways.a and a.

' by a bar (1, moved in a vertical direction by means of a chain of links a, and a bell crank-lever a, one end of whlch carrles a roller a operated upon by a cam a,

mounted on a shaft a, which is journaled in the standard A. The bell crank lever a; is journaled to the rock-shaft b, of the front of the machine, Which rock-shaft operates the pressure-rolls 6 as clearly shown in Figs. 4 and 5. The stops a and a, and c and 0 are operated in the guide-ways 0 and are provided with rock-shafts 0 and 0 journaled in bearings 0 and 0, carried by the standard A. The rock-shaft 0 at one end carries a'lever 0 on which I is mounted a roller 0 operated upon by a bar 0 movable vertically by a cam 0 journaled to the standard A A bracket 0 extends from the bar 0 and carries aroller 0, which is operated upon by the said cam 0 A coiled spring 0 1s attached at one end to the lower end of the said bracket and at the opposite end to the said standard A tomaintain the roller 0 in proper contact at all times with the working surface of the cam 0 to thereby insure true vertical alining movement of the said bar 0 to raise and lower the said stops a and a, accordingly.

It may be here remarked that similar brackets and cams are provided at the opposite end of the bar 0 for like purposes. The stops c and 0 are connected with the rock-shafts 0 and 0 by means of the links 0 The opposite end of the said rockshaft c has secured thereto an arm 0 carrying a roller 0, resting upon a vertically moved bar 0 as clearly shown in Fig. 14. Secured to each end of the bar 0 are brackets 0 carrying rollers c, operated upon by cams c Springs 0 are at tached to the lower ends of the brackets 0 and have their opposite ends attached to the standards A to thereby enable the roller 0, to ride upon the working face of the cam 0 to thus impart true vertical alining movement to the bar 0, for raising and lowering the stops c and 0 The. pressure-rollers 6 at both end portions of the machine raise .and lower to press the sheet or board during its forward movement while the series of between rollers I), serve to b and b", as clearly illustrated in Figs; 4,

l2 and 14, the guide I)", being supported by a bracket b secured to the standard A. The brackets 12 and 6, support the boxlike structures 6 for the pressure-rolls b*, as clearly shown in Figs. 4 and 5. v

A belt e, from any suitable source of power passes around loose and fast pulleys e and e provided with a shifter e On the shaft e, carrying the loose and fast pul- "leys e and e, is provided a gear-wheel e,

which meshes with the gear (1, mounted on the shaft d his shaft extends across the machine and i provided at its opposite end with a sprocke e, and a chain 6 passing around a sprocket e. which is mounted on the shaft 6 Said shaft e", is journaled in the standard A and has mounted thereon the cams and 0 operating the stops 0* and c", as aforementioned. The shaft d also has mounted on it the belt-wheel e which by means of a belt e, revolves the wheel 6, mounted on a shaft e, which latter is journaled to the standard A, and extends across the machine. This shaft e also carries similar belt-wheels e and e, which by means of belts 6 and e, operate pulleys e and e to revolve the rollers a and a. v

The gear-wheel d, meshing with the idler gear 0 revolves the gear 0 to impart motion to the shaft 0 extending across the machine and having mounted on its opposite end the gear e meshing with an idler e, to drive a gear 6, which is mounted on the shaft 11, and the said gear in turn gears with pinions e and e. The pinion e gearing with a gear a, and a pinion e drives the shaft a, on which is mounted the two front feed rolls a". The pinion e, meshing with a series of idler gears e, and pinions e drives the centrally located feed rolls a". The last pinion e, of the series mounted on the shaft e drives the belt-wheel e, and through the belt 6 and belt-wheel e", is imparted motion to a shaft 6 which drives one of said rollers a". On the shaft 6 is mounted a pinion e, meshing with an idler gear (2, to impart motion to a pinion 6 mounted on the shaft 6 to drive the other rear feed roll a, at the discharge end of the machine. v

The mode of operation of the machine as hereinbefore described will be explained, as

follows :-The' sheet or board C is fed into the front of the machine against the guide a and stops a and a, and under the guides a, the pressure rolls 1), atthe front of the machine are caused to descend by the-cam a, rocking the shaft b,this presses the sheet or board into firm contact with the revolving feed-rollers a, at the front of the mawill have operated on the edge of the sheet or board to bring it into a positionfor the respective creasers C and C, in sequence to form alternately descending creases of the character shown in Fig. 9, therein, first in one end portion and then in the other end porti0n,-as shown in Fig. 2. Having thus formed the respective end creases, the stops o and a, are withdrawn, and the sheet or board is then free to move forward until positioned by momentary contact with the stops a and a, at which time the creaser 1), will descend to form the side crease I), when the creaser D, rises and the stops a and a, are withdrawn so that the sheet or board may be fed forward by the feedrolls a", against the stops 0 and 0" and holding the sheet or board C long enough to permit the creaser D, to, again descend to provide in the said sheet or board the other side crease c and of a character of creasing such as shown in Figs. 8 and 9; when the last crease is provided, the stops 0 and 0", will be withdrawn, and the feed-rollers a", at the rear of the machine will carry the thus creased sheet or board onto the table a ,for being discharged therefrom into any suitable receptacle therefor.

It will thus be observed from the foregoing description the entire momentary following operations in sequence of the machine as above explained, are automatic throughout, and that the sheet or board as it is fed into the machine along the table (1, thereof, passes through the machine unaltered or changed as to its plane of travel to receive the respective end and side creases board, consisting of meanslocated in one part of the machine to automatically crease the board in one end, means in another part of the machine to crease the opposite end without shifting or feeding said board, means to feed the said creased board forward, means to then crease one side, means to feed said board, side creased forward, means to crease the opposite side and thereby to complete the, creasings thereof and each successive defined operation efiected without shifting said board out of the plane of its travel from the feeding into the machine to the point to permit of its d scharge and means'to then discharge said-board, for being instantly formed into a unit-section.

2. A machine of the character described, compris ng standards having front and rear tables, the front table having an adjustable guide for the board to be fed, stops located in the front of the mach ne'to pos t on said board during its forwa d feed and before anv creases are formed in the board, means to feed said board forward, creasers posit ely actuated to alternatelv crease the board first in one end and then in the other. without shifting or feed ng said board and then after being fed forward contacting with supplemental stops located in the rear of the machine to permit a second creaser to alternately crease first one side and then after the board is fed forward to crease the other side and finally means to release said stop so as to permit the thus creased board to be released from the machine. In witness whereof, I have hereunto set my signature in the presence of the two subscribing witnesses.
