rArER-Box Mnonrnnj.

To all whom it may concern:

Be it known that I, EUGENE H. TAYLOR, a citizen of the United States, residing at Hyde Park, county of Norfolk, State of Massachusetts, have invented a certain new and useful Improvement in Paper-Box Machines, of which the following is a specifica tion, reference being had therein to the accompanying drawings.

My present invention relates to paper box machines of the class known as topping machines by means of which a rectangular piece of paper is applied to the surface of a cover or to the bottom of the boxitself leaving a narrow margin around the edge of the box or cover.

The machine embodying my invention is in general of the type shown and described in the patent to Schoettle and Garrett, No. 1,032,781, dated July 16, 1912, in which'there is shown and described a machine having a rest on which the cover or box is placed, feeding mechanism for supplying the paper,

and jaws for severing the paper, the aws and the rest being connected in such a manner that the pressure exerted by the operator I on the covering paperto cause the covering 1 paper to adhere to the box or top depresses the rest and causes the knives to severthe covering paper at theproper point. In the machine shown in saidapplication the paper isdrawn out by the depression of the box that the paper remains stationary during the cutting. Furthermore to obta n satisfactory action of the severing mechanism under these conditionsI find that the knives should operate in the same manner as a pair of scissors,

zieflthe cutting point should travel across from one side of the paper to the'other. It

is also desirable that the paper shall not be displaced vertically by the action of the knives. To accomplish this the cuttingpoint' must always be on the samelevel.

The machine embodying my present invention provides means'for cutting the paper as stated. 1

It also provides means for adjusting the length of the paper betweenthe pasteroll and the jaws sothat the paste or other adhesive on the paper shall be exposed to the air for a variabledengthof time sufiicient to allow the adhesive to dry and become taQ TY theother end of the spring beingheld in Specification of Letters Eatent. Patented Nov, 10, Application filed March 5, 1312. Serial No.681,702, I

which is the proper condition for application to the box.

. vl\ ovelmeans are'also' provided to enable the paper to beithre'adedthrough the ma chine more easily.

The invention will be fully understood by reference to thefollowing specification taken in connection with the accompanying drawings, and the novel features thereof are pointed out and clearly defined in the claims at. the close of this specification.

Referring to thedrawings, Figure 1 is a side elevation of 'amachine embodying my invention. 'Fig. 2 is a front elevation of. the machine shown in'Fig. 1. Fig. 3is' a top plan'view. Fig. 4 is a section on line 44 Fig. 2 on a somewhat enlarged scale. Fig. 5 is a detail of the adjustable guide finger. Fig. 6 is a viewof the knives showing their respectiveinclinations. I

In the drawings, a suitableframe for the machine designated at A, is provided to sup port the various working inst'ru'mentalities.

At 11 is indicated the reel upon whichthe roll of covering paper is supported. The web of paper is designated 12. After leaving the reel, the paper passes under an adjustable yguide 13, pivoted at Hand provided with a finger 15 coeperating with a corresponding finger'l6 which contacts with the underside of the pap'einy The finger 15 is held against the paper with a yielding pressure by means of a spring 17 on a swinging rod 18 pivoted at l9 to the'frame of the machine. .The connection between the adjustable guide 13 and the swinging rod 18'is made by means of a pivoted block 20 in which the rod 18 is free toslide, and against the upper side of which: the spring :17 presses,

place by a thumb screw 21. It will be-seen from the drawing, thatp'ivotlle is at'the rear oft'hepivct 19,.and that, therefore, the adjustable guide will remain" in the position shownin dotted-lines in Fig. 5 when thrown back. {This device forms a convenient means for placing the proper tension upon the paperat this point and'at the same time one which may be instantlymoved outpf the way whenitis necessary to thread the paper through the machine. I j

After leaving the adjustable guide 13, the web of-paper "12 passes overthe paste roll 22"whieh deposits paste or other suitable adhesive from the paste pan 23 upon the under-surface of the web of paper. The paste pan 23 is preferably provided with some heating means, such as the steam pipe After leaving the paste roll 22, the web of paper passes between two guide rolls 25 and 26 supported adjacent each other on the frame. The roll 25 also distributes the adhesive evenly over the surface of the paper. The paper then passes to thesevering mechanism which will be later described by a route of variable length so that the paper may be exposed to air long enough to render the adhesive tacky. 9 On the back of the frame of the machine are brackets 27 one of which is shown in Fig. 1, which are each provided on their upper surface with a plurality of bearings28, 29 and 30. At the rear end of these brackets 27 is pivotally secured a pair of arms 31 each containing a plurality of notches 32, 33, which themselves form bearings to. receive a'guide roll overwhich the paper 12 passes. The arms 31 are capable of being swung about pivots 3 1 and secured in place in any desired position by means of thumb screws 35. If it is desired to expose the paper to the air for a considerable period of time, the parts are placed in the position shownin Fig. 1, that is the guide roll 36 is P aced n the bearings 29 and another guide roll 37 is placed in the notch 33, the web-of paper 12 being fed from the guide roll 26, over the guide roll 36 and then around the guide roll 37 to the severing mechanism. This position of the web of paper is shown in Fig. 1, in full lines. If a short period of time is required to dry the adhesive employed sufficiently the guide roll 36 is placed in the bearings'28 and the guide roll 37 in the notches 32, the arms 31 being placed in a substantially. vertical position, all as shown in dotted lines in Fig. 1. As will be readily seen, various other combinations may be made with these parts according to the length of time required to render the adhesive fit for application.

Just before passing to the severing mechanism, the web of paper passes over a guide roll 38 with which cooperates a stop finger 39 secured on a cross rod 40. I finger 39 holds the paper. against the roll 38 sufficiently firmly so that afterthe paper has been severed, it will not be drawn back by the weight. of the paperjbet'ween the guide roll 38 and the'iguide roll 37.

At 12 is shown a rest upon which the work is placed. The position of the work is determined by a movable side guide 43, see Fig. 3, and afront guide 44:, see Fig. 41. The said rest 42 is secured to ajbracket 4:5 by means of the clamp screws 16 and the bracket 45 is itself adjustably securedto a swinging member47 which. is hung from a pivot 48 on the frame of the. machine. The vertical adjustmentof the bracket45 on the The stop member 47 by means of the clamp screw 49 provides for raising or lowering the rest 12 for different depths of boxes or tops to be topped. The swinging member 17 is connected by a link 50 to a lever 51 pivotally secured at 52 to the frame of the machine. A spring 53 is secured to a rearwardly extending portion of thelever 51 and serves to restore the parts to normal position which is the position shown in Fig. 1. The pivot 48 is exactly on-a level with the cutting line ofthe knives so that when the rest is depressed to sever the paper it swings about the cutting line, as an axis and the paper is not drawn out as the cutting takes place. Also while the rest is for convenience of operation slightly inclined, the bracket 415 makes an exact right angle so that when the level of the rest is changed for different thicknesses of tops the corner of the top will bear exactly the same relation tothe cutting point as before the adjustment was made. By this means the machine may be set for any thickness of top, without changing the margin which is the amount which the end of the covering paper falls shortvof the edge of the box, this being effected by changing the position of the front stop 14 by the hand clamp 46. I

The two knives which sever the paper are designated 51 and 55, and are secured to two pairs ofarms 56 and'57, each pair of arms being mounted on the same pivot 58 and 59 respectively. The knives 5 1 and 55 are inclined as shown in Figs.2 and 6 so that the cutting of the paperbegins on the right hand side of the sheet and the cutting point travels across from right to left, as shown in Fig. 2. The lever 51 is connected to the right hand upper knife arm 56 (viewed from-the front of the machine) by a link 60 while the right hand lower knife arm 57 is likewise connected to the said lever by the link .61, the point of connection of the link 61 being below that of the link 60. Therefore when the lever 51 swings it moves the upper knife 54 a greater distance than it does the lower knife 55. Therefore if thetwo knives were both given the same both knives movedby one lever thus avoiding a complicated mechanism but obtainin the desired action of'the knives.

At 62 is shown a cross rod which formsa support for the end of the paper after it has been severed so that the end of the paper may be conveniently seized'by the Operator to draw it forward for the next box. It will also be seen that while it is necessary for the operator to reach between the knives to seize the end of this paper, there is no danger to the operator in so doing, because it is necessary to employ both hands to press the paper down on the corners of the box which pressure causes the knives to come together to sever the paper, and therefore the hands are both necessarily out of the way before the knives can be brought together. The machine therefore may be operated with perfect safety.

At 63 there is shown a cap screw in a portion of the frame of the machinewhich serves as an adjustable stop to determine the position of the box rest in itsv normal position, this being the position shown in I Fig. 4.
