Referring to theidrawings, the fram e of my-machinc comprises a base plate 1, and

side frames 2 and 2 which are secured to to their upper edges.

the base plate and project vertically up from it at a sufficient distance apart to receive andsupport between and on them the various mechanisms that comprise the several features of it. These side frames 2 and 2 are braced by a cross shaft 3, which extends between and through them adjacent The top edges of these side standards .are inclined downward from their rear ends 2 for a portion of their lengths, from the end of which they curve upwardly in a short curve 2 and then extend horizontally forward 'for a shortdistance, and this end 2 is the front end of the machine. Upon the side frames 2 and 2 ,'I place another frame, which I term the upper or card'bending frame,

which consists of two sides 4 and 4 and these sides fit the inclined and curved portion of the top edges of the side frames 2 and 2, and are secured thereto. Above this upper or card bending mechanism, there is a card supporting hopper and feeding mechanism, which'is supported by two brackets 5 and 5 which bolt to a cross tie frame 5 that extends across and between the side . plates 4 and 4 andis bolted to them. These directly below and in alinement with its vertically reciprocating plunger 7*, at each complete cycle movement of the machine. These several cycle movements will be fully described hereinafter.

The base plate 1 is a substantial cast iron platc, and is provided with a pair of lugs 5) and" 9, that project from its left hand side. The lug 9 supports a doubl' bearing, which consists of a pair of boxes 10 and 10", that are spaced a short distance apart but are placed in alinement with each other,

and another pair of boxes 10 and 10 also in alinement but spaced apart and arranged to one side of the boxes 10'and 10 The boxes 10 and 10 support rotatably a shaft 11, which is the power driven and the driving shaft of all of the mechanism of my box and label feeding machine. A belt receiving friction clutch pulley 12, and a reciprocal movement friction clutch 13, is operatively mounted on the shaft 11 intermediate of its ends. This friction clutch is movedto grip or release the clutch pulley through the medium of a spanner crescent 13, that partially surrounds a neck portion 13, that is formed in the hub of the friction clutch.

This crescent is mounted on and secured to a shaft 11, that is supported in the bearings 10 and 10 This shaft 11 is slidably mounted in the bear- ' ings 10 and 10", and it is adapted to be connected to a handle, which I do not illus-' trate. as it is a commonly used element, which may be positioned at the most-convenient point to this machine and to the box covering machine that is to be connected to this machine, and is to befdriven from this box andlabel feeding machine. A collar 13 is secured to the shaft near the box 10, and an expansive spring 13 is placed be tween it and the hub of the friction clutch, and acts to normally hold the clutch in engagement with the clutch pulley.

A worm pinion 14- is mounted on and secured to the shaft 11 between the boxes 10 and 10 and meshes with a Worm gear 1%, that is mounted and secured on the end of a shaft 15, whichl will term-the cam shaft, which extends across the base from one side frame 2 to the other side frame 2, and is journaled in bearings 15 that are secured to lugs 15 formed on the lower edge of an (o Z ne shaft 11', in a. beei'in .bending machine to be connected jeet up into than from ilie tziliile.

the feed table, as this right and left hand threaded feed screw allows the side guides to be moved simultaneously and in unison toward the center of the table to fit smaller sized cards, from the position they are shown in, in which position they receive between them the largest cards the machine can feed and bend into loose end boxes. The forward edge of this table is provided at its central portion with a'forwardly projecting lug portion 43:, that forms a resting .lace for the centers of large -car ds which iave;aj-tendency to bend outwardly at the discharge end ,of the feed table. The for ward ends of the vertical flanges 34 of the side guides are provided at their upper and lower edges with projecting lugs 44 and a spindle 45 that is rotatably mounted in the center of the lugs of each of the flanges of each side guide. A collar 46 is secured to the upper ends of these spindles, and rests on the upper lug, and the lower end of each spindle projects beyond the lower lug and a bevel gear 47 is secured to it. These bevel gears mesh. with similar sized bevel gears 48, that are shdably mounted on a square shaft 49, the ends of which are reduced to round shouldered ends, that are journaled in bearings 50. formed in the upper side frames {and 4 to receive them, and partially rotate therein. The bevel gears 48 are secured in adjusted positions on the square shaft when the side guides are moved 7 toward the center 'ofthe feed table to lit different sized cards, by a pair of crescent ended plates 51 which are secured to the lower lugs 44 of the vertical flanges'of the side guides. The crescent shaped end of each plate is arranged to project into a neck 40 portion 53, which is formed in a hub portion formed on each of these gears. Consequently as the guide plates are moved to ward or away from the center of the feed table by their feed screw 39, the gears 48 are moved along the square shaft and are always held in mesh with the gears 47 by v the crescent plates. On each of the spindles 4-5 of the flanges of the side guides, I mount and secure, preferably by set screws 50 54, a plurality of clips 55, which I term card engaging clips. I preferably illustrate four of these card engaging clips on each spindle. These card engaging clips project through openings 56 forl'ned in the flanges to receive them, to swing inwardly beyond the inner surface ofthe flanges, and they are arranged and adapted to stand with their outer ends pointing forwardly toward the discharge end of the feed table and nor- 60 mally even with the inside surface of the flanges, and behind aretaining strip 55", which -is secured to the endof each of the side flanges. These clips are moved by the gears 47 and 48 by means which will be presently described, against the opposite sides of the stack of cards, they being arranged to engage the card next to the end card and move the whole stack of cards slightly backward in the hopper, and thus take the weight of the whole stack of cards oil of the end card, and this end card is removed from the stack of cards and from the hopper by a pneumatically operating air suction impulse action and cooperating mechanism, which I will presently describe. The gear 47 is caused to turn through apa'rtial rotary movement by the gear l8, through the medium of a lever 57, that is secured to and projects from one end of the shaft 49, to the outer end of which one end 30 side of the cam disk (34, which is secured on the cam shaft 15. This cam groove is ar ranged to move the rock arm and rod and bevel gears to cause the clips 55, to swing from their normally forwardly projtwting position along the sides of the flanges of the side guide in which they are out of engage ment with the cards, inwardly from the opposite sides of the hopper and against the cards and backwardly against the cards 1,00 enough to move the entire stack of cards except the end card backwardly in the hopper, and they move easily backward up the slight incline of the hopper on the endless belt, which in turn moves on the rollers. The air impulse device and mechanism that grips the end card and conveys it to the card bender, is constructed and operates as follows: The air ii'npulse'device comprises an air suction nozzle 65, which preferably consists of a rectangular shaped bar of metal, which is provided with an interior air chamber or aperture 66, and the edge of this nozzle that faces the cards is provided with a vertical row of air intake or air suction apertures 67, which extend into its air chamber 66. This row of air inlet and outlet apertures faces the discharging end of the hopper, and the nozzle is made long enough 'to engage the full width of the largest cards the machine is. capable of using. I preferably form the air chamber in the nozzle by drilling a hole lengthwise of the nozzle to close to its lower 'end, and in order that some of the upper'125 card actuating air holes may be closed up; at the top of the nozzle, which is necessaryf when cards of different smaller sizes than the largest the machine will receive are used, as the machine willtake cards varying 1a in size from 20% by 13.; inches square down Y to cards 1% by 3 inches square. I extend sired, and close them, and in order to hold and set the pin at any adjusted point in the length of the nozzle, I place a set screw 69, through its side against the pin. The nozzle is provided .withan air inlet aperture 70, to which a nipple 71 is threaded, and suitable pipe fittings are connected to the nipple and extend to and are connected to an air pump cylinder 72, which is mounted on the base plate of the frame. This air pimprylinderis provided with a suitably packed piston head -73, and with an operatively connectedfconnecting rod 7 1, the outer end of which is'pivotally connected to one end of a rock arni'75, the opposite end of which is pivotally mounted on a shaft the opposite ends of which are secured in the side frani'es 2 and 2'.

(line end of .a forked lever 76 is pivotally secured to the rock arm 75, intermediate of its ends, and its forked end straddles the cam shaft 15. This forked lever 76 is prorided with. a lateral projecting roller 78, that extends into a cam groove 79 formed in one side of a cam disk 80, which is 'set of bending cams,

mounted on and secured to the cam shaft 15. This cam groove 79 imparts recip rocal stroke movement tothe forked lever 76, which rocks or oscillates the rock arm 75, causing it to impart a reciprocal stroke to the piston head 73 in the air cylinder 72, through the medium of the connecting rods 74., and the alternate outward strokes of the piston cause alternate air suction movement and force in the nozzle through the piping connecting the air pump with the nozzle and the air holes that are open to the atmosphere in the face of the nozzle, which when the nozzle is close to the end card oi the discharge end of the hopper, draws it to it by air suction and grips and holds it'and instantly afterward the nozzle is moved back from the discharge end of the hopper and conveys the end card to the card stripping device, which releases it from the suction grip of the nozzle, and they drop onto stop strips 811 in a. position to be acted instantly on by a reciprocating plunger 82,, which moves it into the. first as will be fully explained hereinafter. I

In order that the air impulse nozzle may grip and move and deposit each card and return for another card, it must have a reciprocal ITIGWPl'llPIllJ bcmvecn the discharge end of the hopper and the bending device, and this reciprocal movement is accomplished by the following instrumentalities: The air impulse nozzle is rigidly secured to one end of a. reciprocating bar 83, that is slidably mountedin a slot that is formed in. a lug 84, that forms a. guideway for it, and that is formed in a cross tie, 85, cf the machine; the. opposite end of this leser is pivotally secured to orie end of a link 86, the opposite end of which is secured to one end of a rock arm 87, which is secured on a shaft 88, by a set screw 89, that extends across and is secured in the ends of a pair of upwardly and outwardly projecting brackets 90, that are secured to the top side edges of the hopper frames 4 and 4:? by cap screws 91. The opposite ends of the cross tie are secured to these brackets. This cross tie 85 is provided with a lateral projection 92, that extends from it toward the discharge end of the hopper, that terminates in a forked end portion. The outer end of the forked portion is provided with upwardly projecting lugs 93, against which flat straight strips 94 are secured. These strips 1 term the card strippers, as they strip each card. from the suction grip of the air suction nozzles on the rearward card carrying stroke of the nozzle, as the sides of each card strike against this stripper and stop it, while the nozzle passes by the forked ends of the pror jet-ting lugs, and these stripperson the back ward stroke a short distance, and the strippers release each card from the nozzle at point that allows it to drop from them onto the stopistrips 81, below them; Qne end of i theshaft 88 carries a lever 88-, the free end of which is pivotally connected to a yoke end 9 1 ,',which is adjusthbly secured to one end of a rod 95,.the ,oppositc end'of which is adjustably secured to, a. yoke'end 96, that is pivotally connected to one end of a lever 97. lEhe opposite end of this lever 9.7 is keyed tp a stud pin. 98, which is pivotally mounted inandextends through an aperture formed through the adjacent side plate.

This pivotal stud pin extendsirom the out side of the side'plate through and beyond gt far enough to receive one end of a lever 921- which is mounted on and keyed to it, and

the opposite end of this lever 99 extends to the outer side of a cam disk 101, and is provided at its end with a laterally projecting roller 102, Which-projects into cam groove 103 formed therein. This cam groove 103 and the coiiperating lever members and connections, with the nozzle, are so relativelyi arranged that a reciprocal stroke morcmen' is imparted. to the nozzle that operativel moves the cards from the discharge end of the hopper to the strippers, and far enough beyond them to allow each card to drop down past the nozzle before it makes its return stroke. Below the strippers, curved chute plates 10% are secured to brackets 105, which are secured to a cross tie 106, that is extended between the sides 4 and t. curved chute plates act to guide each card These a card strikes the stop stripsfil, it is en gaged by a plunger plate 82, that is securedto the end of a reciprocating bar 108 and is moved against vertical bending rolls 109 and109, that are. arranged to bend the end flaps of the cards, as w ll be presently explained. This reciprocatin .bar is slidably mounted in a lug 110, that 'epends from the center of the cross tie 106, and also in a slidesha ft way 112, that is formed in the center of the cross tie frame 5 that is secured to the frame 4 and -1 of the machine, and its reciprocal movement is imparted to it by lever and link connections that extend from it to and are connected to a cam groove in a cam disk on the cam shaft 15, which will be fully described hereinafter.

The stop strips 81 consist of a pair of flat thin strips of metal that are secured at one end to a pair of right angular shaped brackets 113; the opposite portions of which are provided with recessed ends 114, which fit slidably and adjustably over a horizontal bar 115, which is adjustably supported upon a vertical post 116 by' a bolt and a butter fly thumb screw, as shown. This vertical post 116 is secured to a head rail 117 by cap screws 118. The horizontal bar is provided with slots 119, and the brackets areadjustably secured to this bar by butterfly thumb nut screws 120, which extend through the slots and are arranged to clamp the brackets to the horizontal bar in adjusted position, toward or away from the vertical post, which is positioned in the center of the bending rolls to permit these stops to receive the smallest, as well as the largest size cards as'they drop from the strippers.

This vertical post 116 is provided with a slot and the'horizontal bar, together with its brackets and the stop strips, can be raised and secured tothe stop postin ad usted positions. The horizontal bar and the vertical post prevent the cards from falling out under the plunger and back of the side bending rolls.

The plunger plate reciproc'ated to move the cards against the side be g rolls by the follruving "nism: To the under side of the bar we, a ip i2 is secared, to which one end of a link. 1% is pivotally connected, the opposite end which is pivotally connected to one end of a lever 1:25 that is pivotally mounted on. the A lever extends from the hub of the lever 125 and substantially at right angles thereto, the free end ct which is piv otally connected to one end of a forked lever 12'2", the forked end of which straddles arranged to impart an intermittent step and oscillating movement to the forked lever and the link and lever connections between it and the box, to reciprocate the card plunger plate to operatively move each card against the end and side bending rollers and into the box corner, as will be fully described hereinafter; The bending rolls 109 and 109 consist of two vertically disposed rolls that are of triangular shape in cross section throughout their length, except at (their lower ends, Where they are provided with an off-set portion 130. This oif-set portion is provided with a depending hub portion 131. which fits into and is pinned or otherwise secured to a socket shaft 132. This socket shaft extends rotatably through a bearing block 133, which is secured to the top of the head rail frame 117 and down into a slot 134, that extends longitudinally i throughout the length of the head rail frame. The lower end of this socket shaft projects below the bearing block 133, and on it a bevel gear 135 is mounted, which meshes with a bevel gear 136, that is provided with a square axial aperture and is loosely and slidably mounted on a square shaft 137, the opposite terminal ends of which are turned round and are rotatably mounted inbushed bearings formed through the side frames 4 and 4. One end of this square shai 't projects beyond the frame 4*, and a lever 138 is secured thereon, which is connected. by an arm 38* with one member 38 of a rocking lever, the other member 38 of which is operated by a driving cam that is mounted on the cam shaft, which connection will be fully described hereinafter.

There are two of these vertical end flap 109, is in all respects like the other side:

bending roll 1-09 and is provided with a similar socket shaft eonnection 132 and with a s'milar hearing block 133, and the lower and of the socket shafbis provided with a sir "lar bevel gear 135, which meshes with similar bevel. gear 136, that is also slidably lllfll'lilled on the square shaft 137, the same as the other ge-ir 136. The object of slidably mounting the side bending rolls and their supporting socket shafts and driving gears, is to enable the bending rollsto be moved together in unison and" toward and away from the center of the machine, which defined by the vertical post 116 to receive and bend the end flaps of cards from the smallest to the largest sizesthe machine is made for.

isomer t? l shaft causes its-threaded portions to move the bearing blocks and the end bending rolls slida'bly along the slot of the head rail frame. One end of this threaded shaft eX- tends beyond the frame land. is. arranged to I receive a; crank wrench, by which it may be manually turned.

The bevel gears square shaft 137 by means of crescent levers 141 which are secured 133 at one end and extend into neck portions 142 formed in the hubs of these gears. Ehe square shalt 137 is preferably provided with hushed bearings in the frames d and -l* in order that it can be readily withdrawn. This shaft and its gears and the end bending rolls are given an oscillating movement through the medium of the lever 138, which is pivot- 1 ally secured to one endoithe arm 38 the opposite end of which is pivotall secured to one end of an arm 85 the opposite end oi which terminates in a hub 38 which is pivotally mounted on a pin that is secured to the left hand frame From the opposite side of this hub, an arm 38 provided at its end with a cam roll 38, which engages a cam glOOVG formed in the outside face oi a cam disk 38 which is mounted on the cam shaft15,outside of thelcft hand frame l. The cam groove of this cam dist: 38 is arranged to give an eccentric throw move ment to the double armed hubbcd levers 88 and 38, a nd to the arm 38* that will impart an oscillating stroke to the gears and end bending rolls of suii :nt movement to bend the end flaps oi the cards, as shown in. Figs. and These bending rolls are hollow, being each provided with an. air chamber 143 that extends lengthwise of each of them through their card end bending portions, and from the e chambers a vertical row of air suction inlet apertures 1 14i extend through the shell of that side oi each bending roll that faces the plunger plate 82. The air chambers in these end bending rolls are preferal'lly round holes that" are drilled down into them. Each bending roll provided with an inlet nipple, to which one end of a flexible tube 145 is connected, the opposite ends of which tubes extend to and are connected to an air pump cylinder 146, both pipes being connected into one shaft .139 is th'readedly a suction air force in I to the bending rolls and holds them 136 are moved along the to the bearing blocks end flaps and projects, that is side of these rolls and they move around .flaps with them, thus breaking and the lever 13S,"

ystops aga n, which I nee-ted intermediate of its ends, to one end of a fOl'liQd lever 14:9, the forked end of which straddles the cam shaft 15. This iorlred lever is provided with a laterally projecting roller 150, intermediate of its ends, which projects onto a cam groove formed in the groove is arranged and adapted to impart,

through the medium of the forked lever, the

rock arm and the connecting rod and piston. the pump cylinder 1.46, flaps of the cards tightly there while the flat sides of these bending rolls make their oscillating movement and bend which draws the end outside face of a, cam disk 151. This cam and break them along their scored lines, as

shown in Figs. 32 and 33.

The plunger, whichis of the width of the body of the size of cards being run through the machine, and which requires changing to fit each size cards when the size of cards is changed, moves on its card feeding stroke with an intermittent step by step movement, which is as follows: When a card drops from the strippers onto the stop strips this plunger moves against its central body portion inside of its side and end flap portions and moves it up against the sides of the bending rolls and stops there, while thee-1r suction grips its draws them against the fiat and carry the end the cards along their scored lines, as above mentioned. The rolls. then turn back and then the plunger starts and moves the card with its bent ends through and past therolls and against the horizontally positioned side flaps bendingrolls, and then the plunger will now describe, but. will state; here that after the side flapsare-w bent over, this plunger again proceeds forward and pushes the now completely formed the ends of the plunger loose end box into the swinging box feeding frame, which will be presently described. after which the plunger returns to the starting point of its reciprocal stroke.

Each of the side bending rolls 152 and 153 consists of end portions in alinement with each other, having anarrow collar portion at one end and along roller portion adjacent to its opposite end portion, and with a long triangular arranged flap bending portion that is arranged eccentric to the axis of the round end portion, between the-two collar portions, the center or thinnest edge of which is along the axial center of the collars andopposite end portions of the rolls.

The triangular side flap bending portion ofthe rolls is provided with an air chamber 154, which is preferably made by drilling a hole down intoit from preferably its narrowest collar end. The face of the triangular flap bending portion of the roll is provided with a row of air suction apertures 155,

that extend through it into its air chamber,

all of said apertures, as well as all of the apertures in the endbend'rolls, being employed in forming boxes of the greatest dimensions of which the machine is capable, but when blanks for boxes of smalleh'sizes are used, the apertures both in the end and side bend rolls, outside the ends and sides of the blanks are closed by pasting paper over them, or by covering them with a suitable adhesive material. Each of these bending rolls is provided with an air passage nipple, and apertures that enter the air chamber within them, and suitable piping is connected to and extends from each roll and is connected into one pipe which is connected to an air pump cylinder 156, which is provided with a suitable piston and connecting rod 157, which is connected to one end of a rock arm 158,

' the other end of which is pivotallymounted on the shaft 7 5 This rock arm is connected intermediate 'of its ends, to one end of a forked lever 159, the forked end of which straddles the cam shaft 15.- This forked lever is provided with a laterally projecting roller 160, which projects into a cam groove that ,is'formed in the inside face of the cam disk 80, that is mounted on the cam shaft 15.

This air pump during the outward strokes of its piston, creates an air suction force in each o the side bending rolls that draws and grips he cards tightly against their card engagi .ig surface of each roll while therrolls are bending the sideflapsof the cards around the side edges of the plunger, which, when this suction action occurs, has moved a card past and from the end bending rolls against these side bending rolls.

The side bending rolls are pivotally mounted at one end in head blocks 161, and at their opposite ends in bearing brackets,

which are bolted to bracketarms 162, which are bolted at their opposite ends to the head blocks 161. These'liea-d blocks are provided with shouldered slideway portions which fit slidably in a vertically disposed slideway rod is rotatably mounted in a suitable cap 165, through which it extends, and its terminal end is arranged to receive a suitable Wrench by which it may be turned. In order to prevent the accidental turning of this threaded rod under the weight of the bracket arms, I thread a set screw 166 through the cap165 against it. The side bending rolls 152 and 153 are rotatably mounted to stand facing each other. Art the outer free ends of the arms they are rotatably mounted in bearing brackets 167, which are secured to the ends of the bracket arms. The ends of the bending rolls which are journaled in bearing apertures formed in the head blocks, extend beyond the head blocks, and a pinion spur gear 168 is mounted onand secured to each end. These spur gears 168 mesh with spur gears 169, which are mounted on and are secured. t6 the hubs of bevel gears 17 0, that are rotatably mounted on stud bolts, that are threaded into the head blocks 161. The bevel gears 170 mesh with bevel gears 171 that are slidably mounted on a square shaft 172. The

upper end of this square shaft is rotatably journaled in an extension 173 of the cap 165. At the lower end ofthe square shaft 172, there is a bracket bearing 174, that is secured to the frame 4 of the machine by cap screws.

On the lower end of the shaft 1.72, is a bevel gear 175, the hub of which fits rotatably in the bearing 174 and extends beyond it far enough to have formed in it a neck portion in which a yoke or crescent shaped plate fits loosely, which is secured to the adjacent end of the bearing by screws 17 6, and is adapted to secure the gear in the bearing, The bevel gears 171 on the square shaft are held in mesh with the bevel gears-170, as the bevel gears and spur gears are moved toward or away from each other, by the turning of the threaded shaft 164 to adjust the side bending rolls to fit the different sized cards used in the card bending and feeding machines, by crescent plates 177, that are secured at one end to the head blocks 161, and are provided with a recessed end that fits loosely over and in a neck portion that is formed in the hubs of the gears 171. The lower gear 175 meshes with a bevel gear 178 that is supported on a stud screw that is secured to the frame 4, and on the hub of this gear 178, one end of a lever 179 is secured, the opposite end of which is pivotally secured to one end of a connecting rod 180, the opposite end of which is pivotally con nected to one end of a rock arm 181, at the pivotal center of which. a hub is formed, which is secured to the frame 4 by a stud screw, and from this hub an arm 1.82 extends, the end of which is pivotally secured to one end of a forked lever 183, the forked end of which is arranged to straddle the cam shaft 15. This forked lever is provided. intermediate of its end, with a laterally projecting roller 184 which projects into a cam groom formed in the inner side of the cam which are provided with lateral pins 191,- disk 64, which is mounted on the cam shaft which carry rollers 192 that slide recipro- 15.

The carriage is provided at the center of its rear edge with a pair of ears 201,between which is pivotally secured one end of a link 202, which I term a box carrier link. the opposite end of which is pivotallv connected to one end of a rock arm lever 203. the opposite end of which is integrally connected to one end of a long hub 204. that is mounted on the shaft 205, that extends between and through the side frames 2 and 2. From the opposite end of this hub, but in line with the lever arm 203, projects a lever 206. which is pivotally secured at its free end to the end of a forked lever 207. the forked end of which straddles the cam shaft- 15. This forked lever is provided with alaterally projecting from a registering table onto the platen '7 of a box covering machine at the same time or a trifle in advance of the instant the loose end box arrives at the centefbf theplaten 7, in order that the loose end box may be deposited centrally on top of the label. so that the plunger of the box covering mach' c inay carry both the box aud'its covering la el into the box covering machine and cover it in a manner well knpwn in-the art of making paper boxes; This abel feeding mechanism consists of a bar 209, preferably a square bar. which is supported in bearings'210 and 211 that are attached to the box coveriiig machine in any'suitable manner. This bar 209 is a square"reciprocating bar and is conscquently shdably mounted in the bearings 210 and211. It is also necessary that t turn or oscillate through a part of a full revolution .on its longitudinal axis, and in order that itmay accomplish ,both ,a longitudinal and a a partial rotative or oscillating movementon tsaxis'ln itssupportiufr bearingrsg I arrange these hearings in the following manner: The

a bearing 210 comprises a bracket that is de l tachably secured to the frame 2}, of the box covering machine. The free end of this bracketis provided with a capped journal box, in which a sleeve 212 is rotatably m'ounted, and this sleeve is provided with a square axial aperture 213,through which the square box 209 extendsslid'ably, while the bar and sleeve are free to rotate orturn through a part of a full revolution, which I preferably limit toa quarter of a revolution. as will be hereinafter fully described. The bearing 211 comprises a capped journal box that projects from a bracket portion that is detachably secured to or forms an integral part of the framed, and this capped journal box is arranged to receive rotatably the hub portion tilt of a bevel gear 215. which extends loosely through and beyond it and is provided with an integral collar 216 at its end. by which it is held against endwise movement in its bearing. square shaped axial aperture through which the bar extends loosely and slidably. audit is this gear which effects through another gear 217 and other cooperating mechanism.-

the quarter turning or oscillating movement of the square bar 20!). This gear 217 is supported on one end of a spindle 218. which is pivotally mounted in the frame 4". and to which it is keyed or otherwise ruudly secured. To the inner end-of the spindle 218,

is rigidly secured a lever 219, the outer, end of which is pivotally secured to one end of a lever 220, which is pivoted at its opposite end to one. end of an L-shaped rock arm 221,

the opposite end of which is pivotally mount- 10!) ed on one end of a pin 222, extending through the frame 2", and upon the other end of which is mounted the hub 38 of the levers 38 and 38. The heel of this rock arm is provided with a roller 223, which is arranged 1105 r to pro]ect into a cam groove formed in the outer face of the cam 12!), which lsmounted on a driving shaft 15. The cam imparts sutli cient movement to the rock arm22l and the lever 219, to cause the gear 217 to turn e 10 quarter of a revolution, which rotary movement is imparted to the gear 215, and itis turned a quarter of a revolution and it turns the square bar 209 aquarter of a revolution.

and -as it does so, it turns an adjustable bracket 224 which is adjustably mounted. on the opposite end ofthe bar 209. This alljustable bracket 224 is secured in adj ust'ed positions by a set screw 225, and it supports at its free end the air impulse device 226,

that grips the blanks and conveys them to the platen 7 of the box covering machine, and releases them at a point where the boxes will register ou-thein. This air impulse box will .be described hereinafter.

The rear end of the square bar extends a shortdistance beyond the bevel gear 215,.and to its end a block 227 is rotatably secured. This block 227 is rotatably mounted on 'a reduced round shouldered portion 228 that is The bevel gear" is provided with a 3.5

which is mounted in the frame 2', whileits shorter member 233 ispivotally secured to one end of a yoke lever an, the opposite end of which is provided with a forked end that extends to and straddles the driving shaft 15, which acts as a support for the forked end of this lever, and permits it to slide reciprocally thereon. This forked lever is provided with a. roller 235 which is secured to it intermediate of its ends. This roller is arranged to project into a cam groove formed in the inner face of the cam disk 38, which is mounted on and is secured to the ram shaft 15. and is arranged to impart a reciprocal throw stroke to this forked lever and to the crank lever 231 connected to it and to the link 230. to impart an intermittent reciprocal. stroke movement to the square bar 209, whi e the block 227 permits the bar to be turned through a quarter of a revolution on the in; operative stroke of its reciprocal movement, as will be fully described hereinafter.

It is essential that the bracketfzlzl at the forward end of'thebar 209, have a quarter turn movement on its backward or inoperative stroke of its reciprocz l movement, in

order that the air impulse box at its end may pass by the form. block 7.? of the box covering machine, because the "form block moves immediately down against the platen the instant-after a finished blank has been deposited at the box registering point of the platen 7, and this form block is consequently in the path otthe retu'rn movement of the outer end of-the air impulse box.

positioned far enough to one side of the form block 7' to entirely clca r it on its reciprocal strokes, but it is necessary that the air un pulse device at its free end be arranged so that on its operative blank moving stroke it will move centrally underneath the form block 7 in order that it may deposit the finishing blanks centrally underneath it. inasmuch as the loose end box that the linishing blank is to cover. is led directly on top of the finishing blank instantlv after C on '{quentl n in order that the air impulse box may avoid contact with the form block 7' on its back. stroke, the. animpulse device must he moved to one side of the form block at the time it starts to move on its backward stroke to grip another blank, and this form block clearing movement of the air impulse device is accomplished by causing the bracket to turn from the downward vertical box is in air gripping relation. to the blanks,

to a horizontal position, which change of position it accomplishes by being moved through a quarter circle turning movement 0 by the bar 209, which quarter turning movement turns the air impulse device also from the horizontal position in which it receivrs and grips the finishing blank, and moves" it over to and deposits it on the platen and continues to the end of its operative stroke, at which point it is swung up and changed from its operative horizontal position into a vertical position before it starts back on its backward stroke, which moves it out of the g0 path of the form block and allows it to pass the form block on its return backward and inoperative stroke. \Vhen, however,fi' t has passed the form block 7", and before it reaches the end of its backward stroke, it is again turned down into its horizontal position and completes the remainder stroke in that position and moves under at the end of its backward stroke another finish'nlgv blank which the air impulse draws downagainst it with 2. gripping force that holds it firmly to it, after which it. again starts on its operative blank feeding stroke and moves it over onto the platen T, and thus repeats the ryclc of its reciprocating 95 movement; and these two quarter turning;- movements of the bar, 20$), its bracket 271 i, and the air impulse blank gripping devig are accomplished by the gears 215 and 217.

'and their cooperating levers and thc c am 00 to a predetermined position on the platen 3T .1

where the boxes to be covered will register on top of them, may he made in a number of ways, but as illustrated. it preferably coin 'irises a membervinhtho form oi a (hailncl bar, which is secured in a longitudinal recess in the bottom of the bracket 22+. This channclbar is closed by a metal strip 236, which is provided with a row of air inlet and outlet apertures 23?, which extend the full length of the strip. This air impulse.

- box'is made long: enough to grip the largest size blanks that are to be used, and when blanks are used that are of'smallersize than the largest size blanks used; the air holes in the strip outside of these smaller ornarrower H blanks can be closed by pasting pieces of paper over-them. The air box is preferably made to feed blanks for boxes of different sizes ranging from about 13%} by 209,; inches squarc,down to boxes of about by inches square.

The table 6 upon which the blanks are placed and registered to be gripppd by the air impulse box, is adjustably and slidably mounted on a supporting frame 238, by

means of a b 'acket 239, that allows it to be moved-and adjustably set by any suitable means toward or away from the platen 7, of the box covering machine, to accommodate it to receive small or large size finishing blanks in a registering position that will permit them to be gripped by the air impulse box, and the bracket 224 may be adjusted to accommodate the air impulse lupx to small or large finishing blanks.

As illustrated, the top of the frame 238 is provided with a bolt receiving slot 240, in which the bra ket 23!) of the table 6 is arranged to lde. and bolts 241, having properly shaped heads. fit into the slots and clamp the bracket 21-39 of the table to the top of the frame in adjusted positions. The air impulse box 226 projects from the horizontal member of the bracket 224, and when in an operative blank moving position stands in a horizontal plane. The horizontal member bracket 224 is provided with an entrance aperture. in fwhich is screwed a nipple .242. to which one end of a piece of hose 243 is secured. This hose extends to and is secured to one end of a pipe 244, the opposite end of which is-secured to the air actuating end of an air pump 245, which is preferably mounted on the base plate of the box covering machine in a position [to be actuated from the driving shaft ,of the machine. This air pump comprises a cylinder, provided with a suitably packed piston head. from which a piston rod 246 extends, and at its outer end it is pivotally connected to one end of a rock arm 247, the opposite end of which is pivotally mounted upon the shaft This rock arm 247 is also pivotally eonnectral to one end of a forked lever 248. the opposite end of which straddles the driving shaft 15 slidably. This forked lever is provided intermediate of its ends with a laterally projecting roller which projects into a cam slot that is formed in the inner face of the cam disk 151, which is mounted on and isseeured to the driving shaft 15.

This cam 15], the forked lever 24S and the roc arm 24 7, act under therotative action discharge end of thehopper, where they are heldby the corner retaining strips 55 until they are moved slightly back'by the clips, when thesuetion nozzle (55 grips the end one and removes it from the hopper. Power is thena'pplied to the friction clutch pulley clips move into engagement with all of the,

pack of cards except the end card, and. move the whole. pack back just enough to take the weight off of the end card, and instantly afterward the air suction nozzle moves against the end card and grips it by air.

suction force and holds it to the nozzle and conveys it against the strippers which remove it from thebnozzle, and it drops onto the stop strips in front of the plunger, which moves it against the end flap bending rolls, at which point the plunger stops until the end flapsfare bent around Lhe ends of the plunger. These rolls grip it by an air suction force and hold it While the flat sides of the triangular segment of these rolls as it turns, carries the end flaps of the cards around the corners of the plunger, as is shown in Fig. Some card boards require that the flaps of the cards be bent around to about an angle of thirty degrees, while othereard boards of stiffer quality or of different thicknesses do not require that the flaps be bent around that far. The air suction holds the end flaps tightly against the flap engaging surface of the triangular shaped flap bending rolls, and they are turned forward to carry the end flaps around the side edges of the plunger and then turn back again into their inoperative fiat flap receiving position. The bent end flaps naturally spring backward a little, but remain at about a bent up angle of about eight to twelve degrees from? the right angles, with the bottom or body portion of the card. The first step forward movement of the plunger and the end flap bending and returning movements of the end flap bending rolls remain but a few seconds of time. The plunger then moves forward again and pushes the card through between the end bending rolls and against the side bending roll-s, where it again stops, and these side bending rolls grip the side flaps by suction and bend them around the side edges of the plunger in the same manner. The box is then formed, and is known as a looserend box, as while its sides and end flaps are bent up, they are loose and free from each other. The plunger again moves forward and carries the box between and past the side rolls and pushes it intothe box carrying frame and between the angular and beveled walls of its clips, and with its bot tom or body portion extending a short disthe taper of the corners to hold the box fromfalling through the' clips and box carrier frame. Having pushed the box into the box carrier, the plunger starts baclg on the rearward stroke of its reciprocal movement, and the box carr er s swungdownand moved forward with its supporting carriage in the slidevvays of their supporting frames, to-:
