Spool-silk is packed. for the retail trade in pasteboard boxes, each comprising a body or tray and a cover. In the preferredform of the boxes which are employed for the purpose the cover has flanges which extend down around and inclose the side and end fianges of the body or tray, concealing the latter. It has been proposed to apply to the end flanges of the body or tray imprints or markings designating the size and color of the contents thereof in order to identify the said color and size and to form in the opposite ends of the cover openings or peep-holes through which the saidmarkings or imprints will be visible when the cover is in place upon the body or tray, thereby enabling the marking of the cover itself to be dispensed with, if de sired, and obviating all liability to the placing of wrongly-marked covers upon given box bodies or' trays after removal of the covers from the latter in making display of the contents in effecting a sale or for other purposes.

The object of my invention is to facilitate the manufacture of box-covers having the said openings or peep-holes in the flanges of the same and also having so-called thumbholes" in the opposite side flanges of a box-` cover, at the lower edges thereof, to facilitate the operation of separating a box belly or tray and its cover from each other by permitting the box body or tray to be grasped and held at opposite sides thereof by the finger and thumb of one hand placed Within the said open thumb-holes, while the boxcover is grasped by the other hand and lifted off thereby.

The invention consists in a novel machine by means of which the openings or peepholesand thumb-holes are all punched at one operation in the respective anges of a boxJ cover.

The invention is illustrated in the accompanying drawings, which latter represent a rbox provided with a cc ver having the openings or peepholes and thumb-holes aforesaid formed in its flanges and also represent a ,machine containing org embodiment of the invention.

In the drawings, Fig ure 1 is a front elevation ofthe said mach ne. Fig. 2 is an end elevation thereof. Fig. 3 is a plan thereof. Fig. Il is a view in section in the plane indicated by the dotted line 4 4, in Fig. 3. Fig. 5 shows in side eleva ion one of the movable thumb-hole dies and its carrying-plunger.

Fig. 6 is a view there )f looking fromthe leftl hand side in Fig. 5. Fig. 7 shows in side elevation one of the movable peep-hole dies and its carrying-plunger. Fig. 8 is a view thereof looking from the li ift-hand side in Fig. 7.

Fig. 9 is a plan vie v,A on an enlarged scale, n

partly broken away. of one of the sets of devices for punching the openings or peep-holes` in the end flanges of a box-cover. F ig. 10 is a partly sectional side elevation thereof. Fig. 11 is a perspective of a box such as has been mentioned hereinabove. Fig. 12 is a perspective of the box body or tray. Fig. 13

is a perspective of the box-cover.

Having reference to the drawings, in Figs. 11 and 12, 1 designates a box body or ray. The upright side iianges of the said box body or tray are designated. 1a 1a, and 1b 1b arethe upright endflanges thereof. The name of the color of the intended contents of the box and the letter which indicates the size of such contents are marked upon the outersurfaces of the endflanges 1b 1'?.

In Figs. I11 and 13 the box-cover is designated 2l the depending side flanges thereof being shown at 2'l 2a and the depending end flanges thereof being shown at 2b 2b. ln the said figures the opening, peep-hole, or Window, as it sometimes is termed, that is formed in each of the end iianges 2b Qbis desi gnated 2. At 2d is the integral bar that is left below the said opening, peep-hole, or window to keep the lower edge of the end flange 2b intact; and thereby strengthen the same. The thumb-hole that is formed in the free lower edge of each depending side flange 2f of the cover 2 is shown at 2e in Figs. 11 and 13.

Referring now to themachine, at 3, Figs. l, 2, and 3, is the bed-plate of the machine, and at 31 31, Figs. 1 and 2, are legs or uprights by Ioo which the bed-plate supported. The bedplate is formed with oppositely -located grooves 3232, Figs. 1 and 3, extending from opposite sides of the bedlate toward the center `thereof and within W ich are mounted the thumbfhole-punching devices, presently to be described. It is formed also with opprosite grooves 33 33, Figs. 2 and 3, extending n om the opposite ends of-the bed-plate toward the center of the latter and within which are located the devices, resently to be de- I' scribed, for punching t e openings, peepholes, or windows aforesaid. At its center the bed-plate is formed with an opening 5,

Fig. 3, extending vertically therethrough, for' 'the escapeof the punchings or chips.

To the bedlate '3 are ap lied positioningr devices for t e covers Whic are to be punched, such .devices comprising in vthe present instance with a foot portion or fiange' 61, projecting horizontally therefrom. This foot portion or flange 61 is engaged by a clamp 7, the inner l end of which rests upon the upper surface of the foot portion or flange 61, while the outer portion of the said clamp, which portion of the clamp is somewhat thicker than theinner ortion thereof, rests upon the surface of the yed-plate itself, asshown'best in F 1 and 2. The clam has combined therewith a cap-screw 8, t e stem of which passes through a slot 71 in the clamp into a threaded hole which is tapped in the bed-plate. By

means of the said cap-screw the foot portion or flange of the corner-guide may be coinpressed firmly between the clamp and the eed-plate, and thereby the corner-guide may b e secured in the desired position. 'l`he'slot- 71 extends longitudinally of the clamp, as shown iii Fig. 3, t'o permit adjustment of the clamp itself toward and from the center. As.

'will be obvious, ywhen the .cap-screw is loo'sened the corner-guide may be shifted toward or from the center and may be turned or swung in any direction into any required position to accommodate a wide range of variations in the size of the boxes operated u pon,

after which by tightening the cap-screw the corner-guide may be secured fixddly in place.

' The thuInb-hole-punching devices are located at opposite sides of the machine. The said devices comprise at each of th c said sides a stand Q,- Fig. Z3, occupying the groove 32 at such side, the said stand having cast-iron boxes 1,0 l.()., Figs. 2 and 3, secured thereto and beingproyided with a fixed guide-block 11, Fig. 3, intermediate the said boxes and with an. upright end portion 12 at the inner end of the stand. The 13 slides in the said boxes 1() 1() and is flatted at 131, Fig. 5, at its under side to fit the top surface of the said guide-block 11. By the cont-act'of the Hatted surface 131 ofthe rod 13 with the top surface of the guide-block 11 the punch-carrying rod is held from turning. The thumb-hole punch or male die 14 is attached, by means of a screw 141, Figs. 5 and 6, to the inner end of the rod 13. In the retracted position of the rod 13 and die or punch 14 thesaid die or punch is shielded within a guard-block 15, lig. 3. The fixed internal or female die 16, Figl. 3, is backed up by the upwardly-extending ort-ion 12 of the stand 9. block 15 by a space of suflicient width to receive between the same'and the said guardblock one of the side flanges of a box-cover when the male die or punch 14 is retracted punch-.carrying radi It is separated rom the guardoutwardly into the opening of the guardblock 15. For the actuation of the rod 13 and its punch yor die 14 a clamping-block (shown at 1,7, Figs. 1, 2, and 3) is adjustably mounted and secured upon the outerend of the rod 13. This clamping-block is formed with a socket or seat 171,. Fig. 2, which r.- vceives the roundedy transversely-extended bar of the T-shaped head portion 181 of an operating-lever 18. The lever 18 is pivotally mounted u .on a fixed stand 182, `which is attached to t e bed-plate 3, andi-t is actuated to move the said rod and punch or die in one direction to effect .the punching by IOO means of anv edge cani 19, Figs. 1 'and 2, on

the operating-shaft 20 of the machine and to move the same in the opposite direction to retract" the said rod and punch or die by means of the contracting spring 21, the latter engaging by one end thereof with the lever and by the other end thereof with the opposite stand 182. y

The peep-hole-punching devices, which are located at o ipositc ends of the machine, comprise at eac end a stand 22, Figs. 3, 9, and 10, occupy-ing the groove 33 at such end, the

said stand 'having cast-iron boxes 23 23v secured thereto and being provided with a fixed guide-block 24 between the said boxes and w1 th an upright end vportion 25 at the inner end of the stand.` The punch-carryingV rod 26 (shown separately in Figs. 7and 8) slides in the said boxes 2323 and is flatted at 261, Fig. 7 at its vunder side to fit the top surface of the said guide-block 11 to hold thel rod and the. punch carried thereby'froin turning. 'lhe rod 26 carries at its inner end thef male die orpunch 27 for forming an opening,

peep-hole, or window 1n one end flange ofa box-cover. the said die or i'uncli bein" sc-.

cured to the said end of the rod by a screw 271, shown in Figs.' 7,8, 9, and 10.

ln .the

IIO

. retracted position o the rod 26 and die or l the two end hanges or" IOv punch 2,7 the said die or punch is shieided Within a guztrd-bioclrl. (Shown best Figs. 9 and 10.) The iixcd internal or male die 29 is backed up by the upward n extending portion 2o at the inner en o' stand 22 and is separated from guard-Modi 28vby a siace of suiiicicnt width to receive between tlhe same and the said gnard-bioch the end flange die or punch is is retracted outwarilly into the opening of the guard-block For the actuation of the rod 26 and its .punch or die 27 a clamping-block 30, Figs, l, 2, andi-3, adjustably mounted andv secured upon 'the outer end of 'the rod 2o. This clampingblock is formed with a socket or seat which receives the rounded transversi-fiy-extended bar of the ishaped head portion 35i oi an o erating--lever 35, The lever 55 is pivota ly mounted upon a iixed stand 352, that attached to the bed-plate 3, and it is operated to move rod 26 and punch or die 27 in one direction to etiect the punching' by means of a side cani 36 upon the lshaft 20, and itis operated in the opposite direction to retract the punch means of a spring 37,

Vthe said spring having one extremi there-.oi

connected with one of thc levers .35 and the other extremity thereof connected with the other of such levers.

In the usev of the machine a box-cover is placed open side down with diagonally opposite corners thereof Within the angles of the corner-guides 6 and with its respective side iange's entered into the respective spaces bctween the guard-blocks l5 l5 and thev dies i6 l'and its respective end flanges entered into the respective spaces between the guardblocks 28 2Sand the dies 29 29, with the :free edges of the iianges resting npon the upper surface of the bed or table 3. The box-cover being thus positioned, the actuation of the male dies by means of the cams upon shaft y 2O results in the formation of the thumb- ,lioles and end openings, peep-holes, or windoive, after which the box-cover is removed 'and a fresh one placed in position to be operated upon. The cams may be set to cause all of the four male dies to malte their. punching movements simultaneously, or the two thumb-hoie dies i4 14C may act at one time and then the peep-hole dies 27 27.

The shapes of the diiierent dios may vary in practice, according 'to the shape which is desired for the thumb-holes of the side flanges and the shape which is desired for the openings of the end flanges. The position of the said openings in the Width ot the box-cover may vary, as desired, according to the position Which is preferred for such opening and the imprint or marking upon-the box-body. Usually the imprint or marking of agiven end iange of a box-body is located next one side of the latter, the imprints or markingsnof of a box-co ver when the male 'such box-body being disposed in diagonally opposite positions with resp-ect toeach other. in the machine shov-.fn in the drawings the punching devices which zio' upon the end flanges are arranged to Form the peep-holes, openings, or Windows in this relation to each. other--that is to say, t1 are arranged in diagonally opposite positions, as shol 'n best in Fig. In such iign e the ,i punching devices and the cornergnides alternate in position with each other at the opposite ends oi the opening 5 through the bed or plate 5?.

To cnalile the punching devices to be adjusted to suit various sizes of box-covers, the stands $5 Q are made adjustable lengthwise toward and troni each other to suit variations in the width of a box-cover, and the stands 2? 22 made adjustable toward and from each other to suit variations in the length of a box-cover. Each yoic the four stands is secured in working position by means of a clamping bolt or bolts, as Fig. 4, the stem of each of suoli boltspassing through a slot x2, that is formed. in the bed or plate 3, and being screwed into a threaded hole which is tapped into the under side of the stand, and a Washer or plate fr being iittcd to the said stem and interposed between the headof the bolt and the under si de ci the bed or plate. Each slot is elongated in the direction of the length of the corresponding stand, as indicatedk by dotted lines in Fig. 3, to provide for the adjustment of the corresponding stand toward and from the center of the machine. In addition in order to permit stands 222 22 to be adjusted transversely to suit dii'l'erent Widths of boxcovers the slots in connection with the saidA stands are wider transversely than the diameters of the corresponding bolts, as indicated in Fig. 4, and the grooves 33 33 similarly are wi der than the stands 22 2.2.
