Divided and this appiication led May 4,

Serial No. 625,074.

T0 all whom it may 'concern Be it known that I. JOHN E. ERICKSON. a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota. have invented certain new and useful Improvements in Feeding Mechanism for Machines for Cutting and Creasing Blanks. of which the following is a specification.

My invention relates to improvements in feeding mechanism for machines for operating upon blanks of fiber board to be used for making boxes, and more especially upon such blanks of a peculiarly thick and heavy nature where it is desired to make unusually strong and heavy boxes.

My object is to provide a machine of improved and particularly simple construction for making the desired cuts in the edges and from the corners of the blanks. which will crease the same both longitudinally and transversely in proper relation to the cuts. which will automatically feed the blanks to the different positions for the successive operations thereupon with absolute accuracy. thereafter delivering the blanks from the machine. which is rapid in operation and easy and certain of control.

Further objects and advantages of my improvements will appear in connection with the detailed description thereof and are particularly pointed ont in the claims.

In the drawings. illustrating one form of my invention-Figure l is a plan of the entire machine. Figs. l". lb. 1C. ld. le are views of the blank. showing the conditions thereof at different stages of its progress through the machine. Fig. 2 is a side elevation of the entire machine. Fig. 3 is a section ou line 3 3 of Fig. l. Figs. 4. 5 and 6 are detail elevation views of the conveying mechanisni. part of the operating drum being shown in broken sections. Figs. 7. S. 9. l0 and ll are views of details of the conveying mechanism. Fig. l2 is a section on line 1?-12 of Fig. 5. Fig. lisa section online lB--lB of Fig. 6. Fig. i4 is a side view of the blank removing mechanism in position for receiving the sheet. Fig. l5 is a section on line lf l5 of Fig. i4. Fig. 16 iS a sectional fletail of the connections to the driving drum. Fig. 1T is a section on line 17M 17 of Fig. l-l. showing an end elevation of the blank removing finger. Fig. 1S is an end view ol the blank removing mechanism and cooperating stop. Fig. 19 is a detail view of the stop. Fig. 20 is a side view of the blank. Fig. 2l is a view of the tripping device on the blank removing mecha nism when aboutto release the blank. Fig. 22 is a sectional elevation of part of the machine showing the means for operating the blank feeding and withdrawing means.

The blanks to be operated by my machine may be of any type of pasteboard composition and of any degree of thickness or weight. it being a` special feature of my machine that it, will perform upon such thick and heavy blanks the operations necessary to prepare said heavy blanks for ready folding into the necessary form for producing the heavy boxes which it is desired to make from said blanks. The mechanism required to perform these operations, therefore. must be ot' particularly substantial type and the feeding devices for the blanks of such a` nature as positively to grip and feed the blanks into the successive positions in which the different operations upon said blanks are to be performed. and said feeding means must be adjusted to cooperate with each of said operating devices so as to position the blanks with absolute accuracy for each successive operation. My feeding device is, however. adapted to feed to and withdraw from successive operative positions any sheet-like members upon which a series of operations is to be performed.

The relative position of the blanks as they are fed through thc machine. together with the operations performed upon said blanks. is shown iu relation to Fig. l by the Figs. lal to le. inclusive. of the blanks a. In the position shown in Fig. 1a. the blank is laid upon the receiving platform of the machine.`

designated generally' by reference character A." From this position. the blank is positively fed to its second position, shown in Fig. lh. where the devices for making the narrow V-shaped cuts and the corner cuts b. as shown in Fig. l". operate upon the blanks. and which devices are represented in their entirety by thc reference character 13. The blank is then fed to its third position in the machine where it is operated upon by the mechanism for longitudinally scoring or creasing the blanks. as shown at c in Fig. IC. which longitudinal creasing mechanism is designated in its entirety by thc reference character C. From this position, the blank is positively fed to its fourth position in the machine Where it is operated upon by mechanism for making the transverse creases d, shown in Fig. 1d, and Which transverse creasing mechanism is represented generally by the reference character D. This completes the operation of the machineupon the blanks, but additional means for removing the blanks from their fourth position in the machine and depositing them outside of the machine in the relative position shown in Fig. le are required and provided, and this blank-Withdrawing means is designated in its entirety by reference character E Each of the means 13, C and D successively operates upon the blanks in coperation with the means for feeding the blanks to their successive operative positions.

Transverse I- beams 3 and 4 secured to standards 1 and 2 have positioned thereon longitudinal I-beams 6 and 7 forming a supporting framework for the operating and feeding devices of my machine. Forwardly extending bars 8 and 9 are secured to the front ends of the longitudinal members 6 and 7, each of these bars 8 and 9 carrying a series of short crossbars 10. To the cross bars 10 are adjustably secured guides 11 and 12. To the crossbars 10 and to` the inner sides of the longitudinal members 6 and 7 are bolted a series of brackets 21. To each set of bracket arms 21, on either side of the machine, are bolted longitudinal guideways 22 provided with interior longitudinal channels, a view of which, showing the cross-sectional form of the guide-Ways 22, is given in Fig. 12. These guide-Ways 22 provide a support for the blanks upon which they are moved to successive operative positions, and also are for the purpose of hous ing and supporting Within the aforesaid channels reciprocatlng feeding devices, of which the forward feeding member thereof is designated 23, and each of the tivo rear members thereof, being identical in form and function, is designated by the reference character 24. The guide-ways 22 extend back underneath the feeding-platform A, as shown in Fig. 1, and the feeding members 23 cooperate to feed the blanks from their position on said platform to the second position to be operated upon by the devices B, as shown in Figs. 1 and 2, stops 25, as shown in Figs. 1 and 3, being provided against which the operator places the blanks to position them for engagement with the feeding means. The feeding devices 23 and 24 are connected to move in unison by links 26, movement of one member thereby cansing movement of each of the other feedingr members. Each of the feeding members 23 comprises a hook member 27 of peculiar Shape, the member 24 having hook members 28 of different shape and differently disposed in the feeding means 24 from the disposition of the hook members 27 in the feeding means 23, and this difference in form and disposition of the respective hook members of the different parts is all that distinguishes the front feeding means 23 from the rear sets of feeding means 24. The hook members 27 are disposed in the forward portion of the feeding device and have a hook 29, a top cam-face 30, a rear cam-face 31 and a central cam-opening 32, all designed to cooperate in a manner and for a purpose to be described. The hook members 28 each have a hook 33, pointing in the same direction as the hook 29 but oppositely with respect to the body of the hook member 28. The hook members 28 are also provided with a top cam-portion 34 and a central camopening 35. Each of the feeding devices consists primarily of a plate 36, having thereon a longitudinal raised member 37, as clearly shown in Figs 7 and 11, and these plates 36 are connected together by the links 26, before mentioned, and slide directly in the guide-Ways 22. In conjunction with the plates 36, and adapted to have a limited movement therealong, are members 38, having thereon longitudinal slots 39, in which the members 37 register when the plates are assembled, and since the members 37 are shorter than the slots 39 the members 38 may slide along the members 36 to a limited extent. Bolted to each of the raised portions 37 of the plates 36 are bracket pieces 40, as shown in detail in Fig. 9, the said bracket portion 40 being off-set at 41, as shown in Fig. 11, a front bolt 42 thereof operating as a pivot upon which the hook members 27 or 28 are adapted to rock. In the forward portion of the member 40 is a slot 42 equal in length to the difference in length of the raised members 37 on the plates 36 and the slots 39 in the plates 38. Through these slots 42` extend studs 43 hav ing thereon anti-friction rollers 44, as shown in detail in Fig. 10, and these rollers 44 are adapted to cooperate with the cam-faces in the openings 32 or 35 of the front and rear hook members, respectively, for the purpose of raising and lowering the hook members 27-28 in the manner hereinafter described.

To a transverse shaft 45, held in a bearing '1l-6 and having thereon a gear 47 in operative connection with driving mechanism at the left hand side of the machine, said shaft 45 passing through and beyond a bearingr in the longitudinal members 6 and 7, as shown in Fig. 1, are secured drums 49, about which is coiled a pair of driving ropes 50`5l. The driving rope 50 passes through un opening 52 in a spiral casting on one of the spokes of the drum, being removably secured therein by the nut the other end of said driving rope 50 being attached to a member 54 bolted to plate 38 of the middle through either of the driving eordh4 ,B0-5t will be uniformly transmitted to eaeh ot the platen 13H. and movement' to the feeding members :is a whole. and nioie espeeially the hook memberV iT- -AQS thereof., must, be et l'eeted through the plates` 3%.

To operate the vani plate 9S in the depending mvnilivr H2 a vani finger V100 is provided. said vain linger living pivoted at 101 to thv plate 70. As shown, the vani finger 100 has a pointed end 102 and a depending portion 1021, liaek ot whivh is a hollowed ont portion 101. these eharaeteristies of the Cam finger being for purposes to be hereinafter deserilivd.

Vv'hen the drum T5 is rotated in a rearwardl),Y dirvi-tion` through the flexible vonnvvtion TS. the forward plate 7'2 and links T1.y thv plate is moved rearwardly. suvh mot ion living upon the plate 00, h v reason ot' thv tavt that thv slot (19 is longer than the extension 07 on the plate 00 registering in said slot. This morena-int of the plate 70 0n the plate (itl will oarrythe vain tingvr100rearward. thv point 102 thereof first entering liet wvvn the vani lug 10o and` the lug 120 on the end ot' the looking and operating memlier 10S). further movement ot' the vani Finger rearwardly against the fixed vain lug 100 on one sdv and the vani lng 120 ou the member 10) on thv other side of said eam tingen will vause thv same to torce the locking and operating memlier 100 downward and with it the vani plate 9H. until the plate 70 reaches the limit o1 thvmovvment on the plate 0G permitted h vthvslottlhwhen the dependingportion 10B ot the vain finger 100 will oeoupy the position shown in Fig. Q0, in whivh. by means ot said vain finger and the looking men'ilier 109 the vain plate 9S is looked in its lowered position. downward movement thereof havingvausvd the earn extension S8 thereon to engage the vani extension 91 on the gripping iinger 90 thereby causing said gripliing linger to swing upwardly into cooperative vngagen'ient with the lilank (c hetween said gripping linger 90 and the gripping finger 95%. The lilank is thus gripped and held lietwevn the fingers 90 and 93, any7 movement or toreo tending to withdraw the blank therefrom operating to cause the gripping fingers to hold vet more tightly by reason of the rolling contact of the gripping surface of the finger permitted by the spring 94. Further movement rearward of the plate Will nowv be transmitted to the plate 66, which will carry the depending member 82 and the blank (t gripped thereby rearwardly until the blank is removed from the machine. The fixed cam 119 may be placed on the gnidervay ti-lat such a` point as will be most convenient for the depositing of the Withdrawn blanks. Then the short arm or lug 11S on the arm 111 first comes in contact with the cam 119, the arm 111 Will be swung forwardly on the pivot 112 and through thc block or extension 110 push or trip the 'lug 120 on the locking member 109 from beneath the extension 103 of the cam finger 100, the said lug 120 riding into the cutaway portion 104 of the cam finger 100, while the lug or arm 118 will ride up on the cam 11!) thus positively raising the cam plate 98 and withdrawing the depending portion 1.00 thereof from coiiperation with the gripping finger Elf), thus permitting said finger to drop and release the blank. The spring 121, attached to the cam plate` 98 at 122 and to a spring holding member 123 fast to the depending member 82 and extending through a slot 124 in said cam plate 98, operates to complete the upward movement of the cam plate and restore the same to inoperative position, in which it is normally held by said spring 121. Upon reverse movement being communicated to the plate 70 from the drum 75, said plate 70 will first be lnoved on the, plate titi, thereby Withdrawing the cam finger 100 from contact With the lug 120 on the locking member 109, Whereupon the spring 113 Will restore said locking member to its normal position, the leaf spring 125 upon the cam finger 100 operating to resiliently hold said cam finger 1n proper position for the neXt succeeding operation of the withdrawing devices. A brake 126 consisting of a leaf spring attached to the plate G6 over the depending member 82 and extending through a slot 127 in said plate GG so as to bear against the wall of the guideway 64, is provided to retard movement of the plate fifi so as certainly to permit the limited movement ofthe plate 70 upon the plate 66 necessary to effect the proper operation of the gripping finge-rs through the cam finger 100. Upon the return stroke of the blank removing device the same will bc brought in Contact' with a V- shaped stop 128 carried by an arm 129 bolted to one of the frame castings as clearly shown in Figs. 18 and 19, said stop coperating with a member 130 of similar shape carried by the depending member 82 in the proper position to register with said stop 128, the purpose of this device being accurately to position and steady the depending members and the jaw or gripping fingers carried thereby for the reception of the edge of the blank as it is fed into its last operative posi'- tion.

The machine is driven from the main driving pulley 131 by a belt 132 connected with any suitable source of power. The pulley 131 is carried by a sleeve 133 which rotates on a stub shaft 134, said sleeve cari ying a pinion 135. The pinion 135 meshes with a gear 136 on a sleeve 137 loose on a shaft 138 extending across the machine and connected by suitable gearing with shafts 139 for actuating the different devices A, B and C for operating on the blanks. The sleeve 137 carries a pinion 140 which meshes With a gear 141 on a sleeve 142 loose on a stub shaft 143. The sleeves 137 and 142 are thus constantly rotated, the sleeve 137 being adapted by clutching mechanism, not shown, operable through link 144 and hand lever 145, to be connected to shaft 138, to drive devices A, B and C, and the sleeve 142 being adapted by clutching mechanism, not shown, operable through link 146 and foot lever 147 to be connected to a short shaft 148 carrying a crank-wheel 14S) for operating a rocking member 150 pivoted at 151 to a bracket 152 bolted on the frame of the machine.

The rocking mcmber150, which is best shown in Fig. 22, is for the purpose of operating the blank feeding and blank Withdrawing means in timed relation. One arm 153 of said rocking member is provided With a longitudinal slot 154, and engaging said slot and adapted to slide therein is a piece 155 which is pivoted to a crank pin 15G of the crank Wheel 149 before considered. iifhcn, therefore, the crank wheel 149 is rotated the piece 155 will. ride back and forth in the slot 154 and the rocking member 150 will be rocked backward and forward by said rotating member 149. At right angles to the slot 154 is another slotV 157 in the rocking member 150 the said slot 157 being formed in the arc of the circle Whose center is at the pivot 151 of the rocking member 150. through the slot 157, so that when the rocking member 150 is rocked on its pivot 151 said slot 157 Will be oscillated over the shaft 148. This not only results in a convenient disposition of the shaft 148 but operates to steady the member 150 in its oscillating movements on its pivot 151. Pivoted to the arm 153 at 158 is a depending arm 159 which carries a rack 160. The arm 159 slides on a` raised member 161 on a guide member 162 which is pivoted at 163 to the frame, said arm 159 being additionally guided by plates 164 bolted to the frame and overlapping the rack arm 159, as clearly shown in Fig. 22. The rack bar 159 has a slot in Which the raised member The shaft 148 passesA 161 on the guide arm 162 registers. As the raek 1GO -is oscillated by the rocking member 150 it is thus constantly held in engagement with the pinion L17 on the shaft l5 upon which are mounted the drums E9 for operating the feeding devices. It will thus be seen that for each rotation of the Crank wheel 149 the rocking member will cause the rack 113() to make a complete reeiprocation in each direction thereby rotating the drums 49 backward and forward and effecting a complete feeding movement and return of the feeding devices. The other end of the rocking member 150 has formed directly thereon a segment 165 in an are having a` center at the pivot point 151 and said segment 165 meshes with and drives a gear 166 fast on a shafty 167 mounted in an upright member 1(38 bolted to the longitudinal frame member (l. the member 1138, in addition to furnishing bearings for the shaft 1,67, providing a` mounting for the bracket arms (35 which support a portion of the guideway t-I for the blank withdrawing devices. The shaft 167 carries the drum 75 for actuating the flexible connections 74 and 78 by which the blank removing device is operated. The gear 166 is loose on the shaft 167 and is provided with a clutching member 169 adapted to cooperate with a similar clutch member splined on the shaft 167. These clutch members are held in clutching engagement by means of a nut 170 threaded on the shaft 167. The shafti 167 is provided with a squared end 171 for receiving a removable hand crank. Upon loosening the nut 170 the shaft 167 may, by said crank, be rotated independently of the gear 16V, the purpose being to adjust the position of the blank removing device on the guideway 67 to adapt the same for removing blanks of different sizes, the stop 119 being correspondingly adjusted on said guideway.

In the operation of my complete machine, supposing a blank to be in each of the three operative positions of the machine, the operator standing atj the front end thereof will llace a blank upon the feeding platform A in Contact with the positioning stops Q5. The operator then presses down on the footlever 147, which clutches the sleeve 142 to the shaft 148, thereby rotating the. crank 149. rIhe crank 149 oscillates the rocking member 150, which simultaneously oscillates the drums 49 for actuating the feeding devices and the drum '75 for actuating the blank removing devices. so that simultaneously the blank in the third operative position is removed from the machine, the blank in the second operative position transferred to the third operative position, the blank in the first operative position to the second operative position, and the blank on the feeding platform to the first operative position. When the positioning of the blanks as above indicated has been completed the sleeve 137 will be clutched to the shaft 138 to actuatc the series of devices for perfclrming the desired sets of operations upon the blanks. which sequence ot' operations may be repgated to any extent required.
