' Toall wh omz't may concern:

Be it known thatLIyEMIL JAGENBERG-y manufacturer, a subject of the GermanEmperor, and resident of 107 Himmelgeisterstrasse, Dusseldorf? Kingdom of "Prussia,-

Germany, have invented certain new and useful Improvements in Machines for Making PasteboardBoxes, of which'the'follow ing, is a specification. l

The present invent on relatesto 'amachine for manufacturing boxesof" paste board or similar material, in which'the sides of the box are covered withpaper or the like, which is folded over at the bottom and the open side. F o'r'foldi'ng over the ends projecting'at the opensida foldingv device is employed with folders, made .inform of levers, which are attached to a slide carrywork. p

The lmprovement consists In an arrange ment of such a character," that the folders inga matrix adapted to receive the piece of are moved during the sideward travel of the slide over'the edges of the box and moved back by .the latter, when the slide has reached its terminal ositioni The present invention is exemplified in. a constructional form. in the accompanying drawing.

Figure 1 is a side elevation of the -ma-; chine; Fig. 2 is a top view of a part of the 1 machine; Figs. 3 and 4 show-the new ar rangement n front elevation on an enlarged scale.

The pieces of work- 1, whioh'have already been cut to size .and ripped are arranged behind each other on. a table 2. The foremost piece is pressed by a plunger at against the plate 5 or the like and ;-will' then be beneath aslide 6 which'is con'nected to alever 7 and-a rod ,8. The ,latter is guided by means of a roller 9 in 'a,cam-diSkllO'in-such a manner, that the.slide willfbe at times. moved downward at a comparatively rapid speed whereby the for e most piece of-work.

will be pushed into--a -ifr'a-mel1lyingiblow it. This frame is of such'a size, that it will just take the piece of work. The space inclosed by the said frameicorresponds to the sect-ion of the box which is to bemade.

The frame is provided on the one side with elastic fingers l2 inclined-toward each other, whilea lever- 13'is disposed onthe' other side of the frame which lever engages witha-roller or a slipper-attached.toit in-a cam disk 14. The said lever 13 is coupled by means of alink member with a sleeve 16 arranged pivotall placeableuon a 1'0 la-The rod 15 is rotatablyjournaled ,andon it is fitted a plate 18 .hav1nga sleeve 17 adapted to receive the rod, the said plate being connected to a frame 11, and arranged in such-a manner, that the frame mus t revolve with the rod, whereas the latter may be axially displaced therein. -To' rod 15 is rigidly attached a plungerI'19,"the section-of which ie'approxibut not separately -dismately equal to'the inside clear space of the box to be made. On the said rod is further. fitted a spur'wheel 20, in which-the rod may be likewise axially-displaced the same as'in'the frame, but which cannot mm mdependently thereof. With the spur wheel .20 meshes a :larger drivenspur wheel 21, which'is'toothedv over a part of its periphery only,iso that itwillproduce a rotation of the movement of' the wheel 20'only during a part 'of its rotation, during which part rotation it will make said wheel 20complete a full revolution; The grooves of the cam disks IOa-nd'jltg-are made of such a shape that theplunger '19 is moved forward immediately. after the piece has been pressed downby; the slide 6, whereby the said plunger will on "passingthrough the frame fold over at rightangles the intended sides of the box, which have "been marked -by'rips. The piece is displaced Icy-the plunger so far that'the fingers.12- will grip slightly over the edges of the sides of the box on the plunger-and retain these in their position. The piece will now be above-the roller 23, which is rotatably fitted to a lever'22 and under action-"of .a spring-or a weight.

VVhen-the strip of paper which is to be pasted 'on has been brought between the roller 23 andtlie box, it will be pressed under action of the springor weight, not shown in the drawing, againstthe box,- whicheommences at this moment-its single revolution, sothat the'box will be covered These lever Q A ,j 1,019,369

vl t-thereiipon further advances the plunger withthe pieoe and the latter is introduced through the first folding device into the matrix 39 in the displaceable slide29. On

this slide is arranged the second folding ldevice,:, Whiclrconsis't-s ofthe folder .pairs 30 31 respectively pivotally fitted tothe slide and coupled bytoothedseg nents. The

one folder of the pair 30 is provided with an abiltmen't arm '70i and. the upper folder of the pair 31 is provided with an abutlnent arni' 71, the said folder reaching'with said arti te,- 71 respectively i'n'to, thegpath' of s stops 72,73 re'sietively provided on the bodyof.tlie machine of .the guide of the 'slidfeg When the slide with the folding device-ls' ioved to one side, and the arms (0, 7ljab itaga1n'st the stops 72, 73"respectively' the'res'pective folders'and also 1the two folders coupled to theni byjthe toot ied segments will heturned'and moved over the edges of .the box. The slide travels together with the folding device and the arms 70, 71 beyond the "stops. 'f-Ihese tl1erefore"again release the foldingvdevice and the fol ders return into their initial position by the action of springs 6",31" before the slide" has reached the end' if its travel. I

At the endof the travel of the slide niatrix-with the piece will'be'opposite' toa second lun er 7 5. which will 'ress the'ends of the paper, which have been folded over the front edges of "the box, against the insides of the latter. 4 This plunger is operated by ineans of a cam disk 77 or the'like against the. action of a spring 76 in front of and into the box. The stops may, as s oivn, befni'ade and arranged in a movable manner, so that on" the-slide returningthe a'rn1s' 70,"71, which ad aptedto fold "said strip over the tom, a slide, lneans'for actuatingthesame, a

' 1. In a machine of the character described, means for providing abox with a covering strip that projects beyond the bottom and top thereof, a first folding device ox botscribed, means for providing a box with a covering strip that projects beyond the bottorn and top thereof, a first folding device adapted. to fold said strip over the box bottom,'a slide, ineans'for actuating'the same, a second spring-influenced 'folding 'device on the slide adapted .to foldthel strip over the box top, a-plung'er for projecting the fold-' ed strip into the box, and abutmentslocated v' intermediate the first'folding device and the plunger for actuating the second folding' device, said abutments' clearingsaid s'e'cond' folding device and causingthe same to be retracted through its spring 'control'prior to the arrival of the slide. opposite the 75 plunger.
