Specification of Letters Patent.

Patented Aug. 9, 1910.

Application filed June 9, 1!?06. Serial No. 321,031.

To all whom it may concern: I

Be it known that I, EUGENE H. TAYLOR, of

Hyde Park, county of Norfolk, State of Massachusetts, have invented a new and useful Improvement in Machines for Making Paper Boxes, of which the following is a specification.

In machines heretofore designed for making paper boxes various problems have been presented which have not been heretofore satisfactorily solved. These problems have related to the gumming mechanism, the feed of the paper, and the folding mechanism,

. etc.; and in general the arrangement of parts so that the machine will accomplish its work quickly and with but little friction. machine of this kind simplicity is a desirable feature.

My machine is an improvement upon a line of machines, one'ofwhich is shown in Letters Patent No. 541,953, granted to me July 2, 1895, and an examination of my present application in connection with that patent will show that the machine has been very much simplified and.rendered available to dola different class of work accurately and We 1. I

Among the features of my present inven- -tion is the blank feed whereby the blank is delivered from the bottom of the hopper to be caught witha'bsolute register on the upper surface of the former on which it finally rests to be folded. Moreover, unlike other machines of which I have knowledge, the.

blank has two distinct movements between the hopper and its folding position, one a short movement to release its edge from the hopper, and the other along movement .to

carry it by its front edge to the folder. For

this purpose two feeding mechanisms are provided, one strictly a delivery mechanism to deliver it to the feed, and the. other a feeding mechanism which grips the edge of the blank projecting from the hopper and carries it to the folding apparatus. This is very desirable because while the blank is supporting the pile of blanks above it there is no projecting edge by which it may be seized and pulled forward into place; and yet only by positively ripping the blank can absolute register be 0 tained. The

necessity for the absolute register of the blank on the former and with the folding mechanism will be apparent when it is considered that a box like that shown in Figure" Ina.

the foldin .feed and s owin 34, to make which the particular embodiment of my invention shown in the drawings is constructed, is perhaps six or eight inches high, pr with the flaps possibly ten or twelve inches high, and a very slight error in regmany times at the .top of the box. In this connection means which it is, believed are new are provided for moving and operating the rippers which constitute the feed, and also or adjusting the length of movement of the ipper feeding mechanism without stopping the machine in its operation.

My improvement also relates to a peculiar mechanism for folding the various parts of the blank against the former, also to the means whereby the same cam is enabled to o erate both the follower and the former a thou h these two parts have movements of difl arent lengths. These together with other improvements to be described below result in-a machine which it is believed is simpler than other machines heretofore built.

My invention will be understood by reference to the drawings, in which Fig. 1 is a plan of a machine embodying my invention; Fig. 2 being a-front eleva-,. tion thereof. Fig. 3 is a side elevation. Fig. 4 is 'a section on line 44 of Fig. 2. Fig. 5 is an enlarged detail showing the relation of mechanism. and former to the also the feed somewhat in detail and the e ector for the finished box. Fig. 6 shows in detail, partly in section, the ejector and the gripper which forms part of the feed, the ipper being closed. Fig. 6 is a detail 6 means for. adjusting the movement of the grippers. Fig. 7 is a plan view of the ripper and ejector as shown in Fig. 6, and Fig. 8 is an edge view thereof. Fig. 9 shows in detail, partly in section, the follower together with the means for folding down the ears of the box blank. Y

In these views the supporting rod and in- .closed shaft are shortened for convenience.

11 is a section on line 11*11 of Fig. 1 1.

Fig. 12 is a'front elevation thereof. Fig. 13

.is a side view of'the blank delivery mechanism; Fig., 14 being a plan-thereof. Fig.'15 isa side view of the former, and Fig. 16 a vertical section thereof: Fig. 17 is a front ister at the bottom of the box is multiplied view; Fig. "18 a top view; Fig. 19 a cross section on line 1919 of Fig. 17; and Fig.

20 an inverted plan. Figs. 21, 22, and 23 are details, Fig. 22 being in section, of a frictional connection to be described below. Fig. 24 is a detail of the paster in plan; Fig. 25 being a side elevation, and Fig. 26 being a front elevation. Fig. 27 is a section on line 2727 of Fig. 26, and Fig.28 a section on line 28- -28 of Fig. 25. Figs. 29 to 33, inclusive,-show the box blank and the various steps in its folding, Fig. 34 being the finished box.

While a machine like thatfis'hown in the drawings may be rendered capable of making boxes of different shapes, sizes, and proportions by changing the former and otherwise adjusting the machine, it is particularly adapted to make a box such as is shown and described in Letters Patent to filson Fiske, No. 712,434, dated October 28,. 1902, from the blank also described in that patent. Such a blank is shown in Fig. 29 of the present drawings. The blank consists of what may be termed a bottom piece 2, from each end of-which project ears 2. The

' sides of the box are formed by the parts 2 .2 the ends by the parts 2*; .2 being what may be termed paste strips against which the ends 2 are pasted in the process of manufacture. 'In addition, the blank has continuations of the two sides 2 2 and of the ends 2 which, however, are not specifically referred to, as in the operation of folding they may be: considered with the parts to which they are attached. They are used to close the top of the box when it has been filled. It will be noted that the various parts referred to in ig. 29 are separated by dotted lines which indicate the lines upon which the box is folded either in the machine or when it is to be used.

In the operation of the machine the blank having been gummed on its under side along the surface 2 and having been laid and clamped upon the former, the first operation is the folding down of the ears .2 as shown in Fig. 30. The next operation is the folding down of the sides 2 2 against the former (see Fig. 31), the paste strip 2 being turned in (see Fig. 32) by the same mechanism which folds the side 2, the ends .2 being the last part folded, after which the gummed surfaces of the box are pressed between the former and end plates against the sides 2 to insure sticking and the former is 5 running pulley B which is engaged with the said driving shaft by a suitable clutch mechanism. The clutch mechanism shown is one well known in which the movable member of the clutch is thrown by a rocker arm B on a rock shaft B which carries another rocker arm B connected by a connectingrod B with 'a rocker arm B on the shaft B which also carries a rocker arm B. This last rocker arm B isconnected by connecting rod B with a lever B hung under thev platform B and operated by depressing one of the rods B. A hand lever B pivoted to the connecting rod B in front of the machine enables the clutch to be operated from that point. On the shaft B is a pinion b, which,

engaging a gear 5 on a shaft 12 carrying a plnion b transmits power to the gear]; on the cam shaft O.

In the operation of the machine blanks are placed in a hopper D, having an opening d in front to allow the lowest blank to be delivered through it. In fact the delivery of the, blank to the feeding mechanism first takes place in the'form of my invention shown in the drawings, but I will postpone the description of the delivery mechanism and describe it in connection with the feedingfmechanism.

The operation of gumming the blanks will first be described. For this purpose I have provided a gum box E, its rear edge being supported on suitable hinged supports 0 of a character such that the gum box may be easily removed for cleaning purposes, its front edge resting on a ledge on the support F Normally lying within the gum box E, but movable upwardly to gum theunder surface of the under blank in the hopper,

are two ummers E each of which is conv by means of a set screw 0 These two arms slide at right angles to each other so that the position of each gummer may be accurately adjusted with relation to the blank.

An adjusting screw. a the rim of which runs in a groove in the arm causes that arm and the frame 6 as a whole to be moved broadside in a direction crosswise of the machine, and an adjusting screw 6 similarly arranged with relatlon to one arm of the might-angled piece a will cause an adjust-' ment of the frame e endw'ise and lengthwise of the machine. After adjustment the several parts are clamped in place by set screws e.

The frame Itself carrles yieldingv gumming pieces 6 e the edges of which are shaped to gum a surface of proper shape, 2, on the end pieces 2 of the blank. These gumming pieces are supported upon springs e which are held in place by pins 6 projecting from the frame The yielding pieces 6 e are connected to the frame 6 by screws a passing through slots e in the umming pieces and are supported lateralfy by fingers 6 It is desirable also that other pins 6 be provided which pass through similar slots so as to form guides for the movement of the gumming pieces 6 I prefer to make these gumming pieces in parts in order that they may conform readily to any irregularity in the surface of the blank.

I will now describe the mechanism whereby the gummers are operated. Each rod e passes up through bearings E mounted on the side of the hopper D. To the side of the hopper is also attached a depending rod E which serves as a guide to the movement of the rod e, the rod 6 for this purpose being provided with a forked arm E the fork of which straddles the rod E. In the operation of the gumming frames they are given a vertically reciprocating movement upward to gum the under blank in the hopper and downward into the gum box where they normally remain. To give each its vertical movement I have shown rocker arms 6 each pivotally connected to its rod e and projecting from a rock shaft E suitably mounted in bearings mounted on suitable supports A This rock shaft extends across the machine and the operating mechanism is duplicated on both sides of the hopper vD, but movement is given to the rock shaft E by. means of a slngle rocker arm E and connecting rod E whichyodis connected with frame of the machine.

a cam lever E mounted on the fulcrum A supported on supports A, carried -by the The other end of th'iscam lever E is provided with a cam roll and runs in a groove of suitable sha e in the cam E mounted on the cam shaft I will next describe the means for deliver ing the blank to the feeding mechanism. As suggested above, I prefer to deliver the blank (2'. e.,- push it out a shortdistanoe from the hopper) before gumming it, and the operation of gumming therefore occurs between the delivery and the feeding operation. This is best in a machine which may be adjusted for blanks of different lengths. This delivery mechanism will be understood more particularly by reference to Figs. 1, 4, 13, and 14, and it consists in two arms, one located on each side of the machine and under the hopper, and each so located that when at rest in its rear position its pusher will be behind but ready to enga e the edges 2' of the end ieces z of the bfimk as will be seen from ig. 4. As shown in Fig. 1 a

slide F is mounted in bearings f on the upper ends of supports F F carried by the table A. An arm F projects from each side of the slide F and is slotted." near its end as shown at P. To each arm F 'is adjustably attached a cross arm F. For this purpose a block F is provided with a shallow groove on its under surface, which enables it to straddle the arm F and it is clamped to the arm F by a bolt 7" (passing through the slot f andnuts f, the upper nut 7 also holding the cross arm F in position in a corresponding shallowgroove in the upper side of the block F. The front'end 0 each cross arm' F is beveled at P and I near its'front end itcarries a pusher F adapted to engage the proper edge of theblank at the propertime and push it forward a proper distance. The upper surface of this pusher projects slightly above the upper surface of the cross arm F so as properly to engage the blank. The beveled edges of the cross arms guide the edge of the blank to the pusher. The grooves in the blocks F guide the direction of adjust- V ment of the pushers. It will be seen that the cross arms F 4 may be adjusted toward and from the middle line of the machine according to the widthof the blanks as 7 above described. To adjust the ushers lengthwise of the machine I .provi e each block F with a screw f on which turns a grooved nut f, the'disk of'which fits into a groovein the cross arm F, the other portion being available as a thumb nut. The groove inthe nut receives the end of the cross arm F.- To adjust the pusher length- 'wise of the machine the upper nut f is loosened and the proper adjustment is made by turning the nut f, after which the nut f is again tightened. It will be noted-- that the cross arm F is slotted as at f in order that this adjustmentmay be made. In like manner the arms F are provided with slots f to enable the cross arms F. to be adjusted toward and from the center of the machine.v The purpose of this delivery mechanism is not to feed the blank 'but'to place the blank within reach of a gripping mechanism which shall serve as a. positiye feed, and it is unnecessary that thls' del very mechanism shall have more The weight of the with an eye: f connected to the under'surface of the strip F, this lever being fulcrumed at f in a projection, above the table,

the lower end of the lever Ipassing down 1'25 provided a gleverF connected by alinkf
