Fig. 10 is a plan view of one of the foldingthe end-closing sections of the blank will lie upper end of the guide-plate Z.

substantially in the plane of the sides of the carrier, and, as in my former patent, a curved guide-plate l is provided, which is supported in the frame of the machine in close proximity to the path of the ends of the carriers as the latter revolve, and the end-closing section of the box, which lies on the under side of the carrier, comes in contact with the upper edge of the said guide-platel and is thereby turned in across the end of said carrier. (See Fig. 15.) At this point an arm m, mounted on a shaft 4%, is made to swing down toward the This arm m is provided at its outer end with a blade 0, which is adapted to strike the opposite end section of the box to that acted upon by the upper end of the guide-plate land fold in that section over the end of the carrierj, all as described in my said former patent. The aforesaid end-closing sections of the box are indicated in Figs. 15 and 16 by the letters 19 and q, Fig. 15 showing said sections partially infolded, and Fig. 16 showing them as they are held during their passage over the guide-plate Z. It is seen that the opposite end-closing sections (indicated by r and .5) lie substantially at right angles to the carrier, and it is while they are in this position that these end-closing sections of the box are subjected to the action of thegumming devices. The said sectionsrand s are forced outward into the plane of the end of the carrier by coming in contact with the flat surfacest of the guide-plate Z, (see Figs. 1 and 3,) which, beginning at the upper end of said plate, gradually taper outward and terminate near the periphery of the glue-wheels u u, where the guide-plate Z is narrowed sufficiently to permit it to pass between said glue-wheels, the latter, as shown in Fig. 3, being separated to an extent slightly less than the width of the box.

The construction of the gumming devices of the machine embodies many features of improved construction over that shown and described in my said former patent and which will now be described.

Figs. 2, 3, 4, and 5 more particularly illustrate the construction of the gumming devices, and referring to Figs. 3 and 4, o indicates ashaft of the machine driven by independent pulleys w. (Shown in Figs. 1 and 2.) On each end of this shaft is a wide-faced gear m, (see Fig. 1,) in mesh with larger gears y, fixed on the outer ends of two short shafts a, hung in yokes l on said shaft 1;. On the contiguous ends of said shafts z are fixed the glue-wheels u u. These are of brass, and their peripheries are provided with annular grooves, as usual. Said yokes l are hung independently of one another on the shaft '0 and may be adjusted in lines parallel with and at right angles to the said shaft. The yokes 1, as shown in the drawings, are hung on a sleeve 2, which passes through the bearings 3 and may be clamped fixedly therein, and said for the shaft 1), which rotates therein.

adjust the glue-wheels tt toward or from each other, the sleeve is moved endwise in its bearings. To adjust the glue-wheels in the opposite directionthat is, relative to the path described by the end of the box on one of the carriers j-the caps of the bearings 3 on the arms of the yokes 1 are loosened, and by means of the adj listing-screws 4 4 (shown in Figs. 3 and 4) said shafts z and the gluewheels 11. on their extremities and the yokes 1 may be each moved as desired towardor from the path of said box end by means of a long screw 5, (see Fig. 5,) which engages the arm 6 and enters the frame of the machine. The end of the arm 6 engaged by the said screw 5 is forked, the slot in which the screw lies being curved and concentric with said sleeve, whereby means are provided for swinging said yoke 1 freely when adjusting it in the opposite direction. Obviously the axis of said glue-wheels must always be substantially the same. The said adj Listing-screw 4 passes through a slot 7 on the yoke 1 and enters the frame of the machine beyond, as shown in Fig. 4. In said frame is a second screw 8, which is adapted to bear against the face of the yoke, (see Fig. 4,) and when the latter has been properly adjusted the screw 8 may be turned up to lock the yoke in position. Hung on each of said yokes near its inner end is an arm 9, on which is a press-roll 10, between which and the glue-wheel u the outwardly-projecting end sections of the box pass as the latter moves over the curved guide-plate Z. This arm 9 is, by means of a screw, (shown in dotted lines in Fig. 4,) adjusted relative to the periphery of the gluewheel, whereby the end section of the box passing beneath it will receive the required amount of pressure to properly apply the glue to the under side thereof.

In my previous patent only the underside of the end sections of the box were supplied with glue; but in the present construction the guide-plate Z has been made narrower, and thus permits the glue-wheels to be placed nearer together,the space between them being somewhat narrowerthan the width of the box end, whereby when the latter passes over the glue-wheels the inner edges of the latter will lap over the folding-line of the outstanding end sections which are to receive the glue, and when the latter is applied tosaid sections it also is applied to a portion of the outside surface of the two sections already int'olded, as shown by the shaded portions of Fig. 1'6, thereby greatly increasing the strength of the union between the under sections 1) qand the sections r s folded over them.

The glue-box 11 is supported on the upper extremities of arms 12, fixed on the parallel rock-shafts 13, supported in bearings on the frame near the floor. (See Figs. 2 and 4.) A hand-lever 14 is secured on one of said shafts, whereby the latter may be oscillated and the glue'box lowered away from the glue Wheels u for refilling or cleaning. A screw 15 in one of the bearings of one of the rockshaftsis screwed up against the shaft to hold the latter against rotation and keep the gluebox in its place under the glue-wheels u. The latter are continuously rotated with the lower portion thereof immersed in the glue, and an improved doctor is provided which bears on the glue-wheels, whereby the requisite amount of glue may be applied to the end sections of the box. This doctor is shown in Figs. 6, '7, and 8 of the drawings and consists of a metal plate having its lower edge turned at an angle to the body thereof, the said edge having one long arm 16, adapted to bear against the outside of the glue-wheel u, and a short arm 17, adapted to bear on the opposite inner corner of the wheel, and between these two wheels the said edge is serrated and each projection 18 of said edge is adapted to bear upon that portion of the glue-wheel it between two of the annular grooves which are formed therein. A guard-plate or fender 19 is secured to the lower edge of the doctor and is adapted to prevent the glue from piling up behind the glue-wheels u and flowing over the edge of the tank. The doctor and fender plates are supported on two plates 20 on the yokes 1, which extend around outside of each of the glue-wheels, forming a sort of boxing therefor, as shown in Figs. 3 and 4. In said plate 20 on the side of the Wheel is a swinging bar 20 which is loosely secured to the plate by its upper end only, and a screw 2O passes through the said plate 20 and forces said arm 16 against the side of the gluewvheels u with any desired degree of pressure.

In my former patent the end sections of the box were guided under converging wires, and thus turned inward over the already-infolded sections of the opposite sides of the box. This construction in practice has some objectionable features which are overcome in the construction embodied in this application and will now be described.

A swinging yoke 21 is hung on the shaft h, one arm of said yoke engaging said shaft on each side of the hub on which the carriers j are supported. This yoke (shown particularly in Fig. 9) is U-shaped and has a reciprocatory swinging movement between the glue-wheels n and the presser-rolls 23 so timed that the yoke 21 meets each of the four carriers j just afterthey have passed the gl uewheels to and then swings with said arms back to the presser-rolls, as stated, and it is during this movement with the carriers that the end sections '1" and s are folded over the sectionsp q, as will be described. Near the bottom of the yoke 21 two folding-wings 22 are supported, one in each arm of the yoke, as shown in Fig. 10, whose function it is to fold inward the end sections r and s of the box after they have been gummed and to press them firmly against the other sections 1) and q, and this operation takes place during the swinging movement of the yoke between rolls 23, as stated, and is effected by the engagement of the arm 24 on said wings 22 (provided with suitable rolls) with suitablyformed cams 25, supported on the frame of the machine in the path of said folding-wings. These cams are shown in Figs. 2, 9, 11, and 12, in the last two figures in plan and side elevation, respectively. Said folding-wings 22 each consists of the rigid arm 24, which pivots freely on a stud 26, the ends of which studs are flattened, as shown in Fig. 9, and adapted to have a sliding movement toward and from each other in the slots 27 in the arms of said yoke 2L. This movement is imparted to these studs by two screws 28, Figs. 2 and 9. Each of these arms 24 is widened, as seen in Fig. 10, to receive the folding wing 22, that portion of which is located on the arm being flat and of substantially the same area as one of the boX end sections 7" or .9. That end of the said plates toward the glue-wheels to tapers out to a point and is given a slightlyconcaved form and bent back slightly away from the path of movement of the box along the guide-plate Z, the outer end of the plate being bent substantially at right angles to the portion thereof on the arm 24 and said point lying normally slightly above the plane of movement of the end sections 0 and s when the yoke 21 is swung toward the glue-wheels to the limit of its movement in that direction. During the movement of said yoke toward the glue-wheels the ends of the arms 24 run out to the extreme end of the cams 25, and the inner contiguous ends of the said .arms 24 beingthe heavier these latter fall apart. As the yoke approaches the glue-wheels the car.- rier 1 passes over the latter, and as said carrier-arm and the yoke approach each other the ends of the folding-wings 22, which extend out toward the glue-wheels, encounter the two sections 7' and s, and as the yoke and carrier-arm meet and the direction of movement of the yoke is reversed these sections have, by reason of the hereinbefore-described conformation of the folding wings, been turned down and somewhat under the guideplate land at this time will lie substantially over the rectangular portion of said wings. As the yoke begins its movement in a reverse direction, as described, with one of the carrier-arms this reverse movement causes the outer ends of the arms 24 to be depressed by reason of their engagement with the cams 25, and the folding-Wings 22 on the other end of said arms will thus be gradually swung up toward the end of the carrier, and as the latter passes off the guide-plate Z the outer ends of the arms 24 reach the lowest point of the cams 25, and thereby force the rectangular part of the folding-wings up against the end of the carrier with as much power as may be desired. Just beyond the point where the carrier leaves the end of the guide-plate Z the cams run up abruptly at the point 28 and re- I lease the wings 22, which drop away from the the glue-wheels and the first of the presser- I end of the carrier, and at this point the m0ve- IIC ment of the yoke is again reversed, and it swings back to meet the next succeeding carrierthe one over the end of which the end sections p q r s of a box have just been foldedpassing on to the presser rolls 23. These rolls are spring-supported and their peripheries intercept the path of the end of the carrier, and in my former patent the contact of the forward edge of the carrier effected the depression of the first of these rolls. It has been found in practice, however, that the contact of the edge of the carrier with the first of these rolls 23 would frequently cause the end sections 1' and s to slip on the other sections to which they had just been gummed, because said sections had not been suificiently pressed together to cause them to firmly adhere. In the present construction, therefore, means have been provided for depressing the first of the said presser-rolls 23 at the moment the end of the carrier is about to pass over it, and before the edge of the carrier strikes the second of the presser-rolls the first roll is released and its spring forces it in against the end of the carrier, thus putting the gummed end section of the box under pressure just before they strike the second roll. By this means the said end sections r and s are firmly held in place until they are fairly entered on the rolls, after which there is practically no danger that the end section will be moved by their contact with succeeding rolls, because two rolls are always bearing thereon at the same time, some at the moment of contact with the first roll. The mechanism whereby the yoke is given its swinging movement and the first of the presser-rolls 23 is depressed and released at the proper time will now be described.

The mechanism for reciprocally swinging the yoke consists of a cam 29 on the shaft 6, Fig. 14, with which an arm 30 engages by means of a suitable cam-roll on the side of said arm. One end of said arm is forked and straddles the shaft 6 and is thereby supported, and the opposite end, as shown in Fig. 14, is pivotally connected with an elbowlever 31, which isfixed on the end of a rockshaft 32, and on this rock-shaft is a depending lever 33, from the lower end of which a rigid connecting-rod 34 extends to the bottom of the yoke 21. This connection is pivotally secured to the yoke centrally between its arms at the lowest point thereof, and is shown in dotted lines in Fig. 14, and is indicated by 35. One revolution of the cam 29 will swing the yoke from the presser-rolls backward to meet one of the carriers, and thence forward again to the point where the carrier passes onto the said rolls, as described. The means whereby the first of said presser-rolls 23 is depressed at the moment the carrier is about to pass onto it is also shown most clearly in Fig. 14, and consists of two arms 36, (see Fig. 14,) one of which is pivotally hung on each end of the first of said presserrolls 23, and whose opposite ends are pivotm st ally connected with the ends of two levers 37, fixed 011 a rock-shaft 38, on one end of which is an upstanding arm 39, from the extremity of which a connecting-rod 40 runs to the lower end of the elbow-lever 31. The end of the rod 40 connected with said elbowlever is provided with a long slot 41, through which a stud on said elbow-lever passes, and in the outer end of said rod 40 an adjustingscrew 42 is provided, Whose point extends more or less into said slot 41. By means of this construction when the cam 29 operates through the described mechanism to swing the yoke 21 toward the presser-rolls at the proper moment the stud in the end of the elbow-lever 31 comes in contact with the end of the screw 42 and imparts to the rod 40 an endwise movement, which partially rotates the rock-shaft 38 and through the described connections depresses the first of said rolls 23 until the forward edge of the carrier has passed over the center of the roll, which is then released and by means of the springs on which said roll is supported causes the latter to come to a bearing against the end sections 1 and s of the box before the forward edge of the carrier strikes the second roll. Thus there is no danger that the impact of the edge of the box against the presser-rolls will cause the sections 0 and s to slip edgewise on the under sections 19 and q and throw the bottom of the box out of its proper rectangular form. This is very important, for many of these boxes are used in automatic package-filling machines, whereby they are filled with material, and many of which are provided with pockets adapted to receive said boxes, and in which the latter fit snugly, and there is difficulty in introducing said boxes in the pockets if the latter are distorted in shape.

Taking up now the means for stripping the boxes off the carriers, it has been found in practice that the means provided in my former patent are for certain reasons objectionable in that the stripping-yoke (indicated in this application by the numeral 43) did not have time to remove the box from the carrier while the latter was passing by said strippingyoke without too great a red notion in the speed of the machine. Means have therefore been provided in the present construction which overcome this objection and will now be described. The said stripping-yoke 43 operates to remove the box from the carrierin precisely the same manner as does the same arm in my said former patent, viz: The carrier passes between the two arms of the yoke 43, each of which is provided with the fingers 44 in the extremities of the arms of said yoke and adapted to engage two opposite edges of the box, and as the carrier and yoke continued their rotation on their separate axes, the said fingers would draw the box off from the car rier. To provide-for giving the said yoke a longer time for Withdrawing the box from the carrier, I provide for shifting the axis on which the yoke 43 swings, whereby, while the said stripping-fingers are moved longitudinally of the carrier by the swinging of the yoke on its axis, the yoke is made to follow the general direction of movement of the carrier, and thus the ends of the fingers 44 may remain longer in contact with the ed ges of the box, and thus insure its withdrawal from the carrier in good shape. 'lo effect this movement of the stripping-yoke 43, it is secured to the rock-shaft 45, which shaft is in turn supported in parallelism with a rock-shaft 46. (See Figs. 2 and 14.) On the end of the rock-shaft 45 is fixed an arm 47, provided with a stud 48 at its extremity, which engages with a cam-groove 49 in an arm forming part of or secured to the frame of the machine. 'lo said stud is also secured one end of a lever 50, the opposite end of which extends to and straddles the shaft e and has a cam-stud 51 thereon, which engages the groove of the cam 52, whereby at the proper time the said lever has imparted to it an endwise movement, whereby the stud 48 is caused to follow the cam-groove 49 nearly to the end thereof, the shape of which is such that the resultant movement of the stripping-yoke 43 will be substantially in the direct-ion of the receding carrier after it rises beyond the horizontal position it occupies in Figs. 2 and 14; but during this movement said end of the yoke also has im parted to it a swinging movement on its axis away from said carrier. The arm m on the shaft a is swung downwardly at the proper time to fold in the end section g by means of a cam 53, also on the shaft 6. (See Figs. 1 and 13.) One end of a lever 54, having a stud 55 thereon, which engages with said cam, is forked to embrace said shaft 6, and the opposite end of said lever is pivotally connected with a short arm 56 on the shaft 71. The form of the cam 53 is such as to impart to the arm m the requisite quick descent to infold the said section 1, as described, and the means for operating said arm are substantially the same as shown and described in my said prior patent. On the driving-shaft b are the usual tight and loose pulleys 57 and a shipper-rod 58, whereby a belt on said pulleys may be shifted at will. In Fig. 1 of the drawings, in which these belt-shipping devices are most clearly sho wn, there is also shown a shippinglever 59, which is located on the side of the machine opposite to that on which the pulleys 57 are located, whereby through suitable connections said shipper-rod may be shifted.
