BOX-1VIAKING Specification of Letters ream.

Application filed September 3, 1914. Serial in. 8503s T aZZ whom it may-concern.

Be it known that 1, E3111, JAGENBERG, a subject of the German Emperor, and resident of 107 Himmelgeisterstrasse, Dusseldorf, Germany, have invented certain new and useful Improvements in and Relating to Box-Making Machines, of which the following is a statement.

The present invention relates to a box making machine as described in the United States Patent 608,201.

The inventionhas been exemplified in the accompanying drawing.

Figure 1 is a side elevation. Fig. 2 is a plan, and Fig. 3 is a cross section on the line AB. Figs. 4; and 5 show the folding mechanism in two diiferent operative positions. Fig. 1 isan end view'of the paper strip feed locking means and Fig.1 a side view thereof.

Between the walls 1 a pile of-pasteboard strips 2 lieson rubber bands 3, which are laid around rollers 4c, 5. To the roller at is fitted a toothed wheel 6 and also loosely thereon a sprocket 7 and attached thereto a clutch member 8. Toward this clutch member 8 the clutch member-.9 displaceable but 'not rotatable on shaft 4 is pressed by a spring 10. The sprocket 7 is driven by means of chain ,11, which travels over a sprocket 12 on shaft 13. The shaft 1-3 is driven by means of a chain drive H from shaft 15 and drives the rollers 16 by means of the chain drive 17 and the toothed wheels 18. In toothed wheel 6 engages a pawl 19 which is fitted to a lever 20 the free end of which is coupled'by a rod 21 with the lever 23 journaled on shaft 22. On the shaft 22 is also fitted a lever 24, the nose-shaped end of which 25 lies in the path of an abutment 27 fitted to the sprocket 26. The rod 21 has a pin 28 which engages in a slot in the double-armed lever 29. The upper end of this lever is situated in front of a slot 30 in a shaft 31, to which a feeler 32 is fitted which projects between the rollers 16.

When the abutment 27 strikes against the nose 25, the pawl 19 is lifted and the lever 29 is forced through the slot 30, .the shaft 31 turning until the lever 29 has penetrated the slot. Then-the shaft 31 turns back so that lever 29 cannot return. When the pawl 19 is lifted the shaft 4 can revolve. The

' sprocket 7 which revolves continuously can 'ries with'it shaft 4 by means of theclutch members 8,, 9, so that the endless rubber lo v, I L it lifts the feeler Thereby the snaft 51 is turned in such a manner, that the lever 29 can return through the slot 30. in eon-se quence thereof the levers and can rock backward whereby the pawl 19 is reenga and the shaft is is stopped, so that now L18 two clutch members grind on each other. The rollers 16 puslr'wie pasteboard strip hetwecn the walls 33, which are held suspended by the arms 34: and When the pasteboard'strip is here at rest, several bars 3% lower on it and press it down onto the table 37. The bars are fitted to the shaft which is operated by means of a lever 39, a rod i0 and a roller ll from a cam disk When the pasteboard strip lies flat on the table 37, the slides it fitted to the carriage d3 are advanced by means of the grooved disk sh") so that they against a longitudinal edge of the pasteboard strip and force the latter sidewise, whereby it passes through a slot between the table and the one wall 33 and reaches a bar 46. On this bar 4:6 lies a strip of paper 55, which is Wider than the pasteboard strip. This paper strip unwinds from a roller 56 and is passed over gumining rollers 57 and guide rollers 58 to the rail 46, on which it lies longitudinally but h it projects at the sides (Fig. at). Ont-L- this paper strip the somewhat narrower pasteboard strip is advanced.

The bar at; is fitted to a vertically guided carriage 4:7 which is raised and lowered by means of roller 48 and the cam disk Next to the bar -16 an angular bar or first folder 50 is fitted to a vertically guided can riage 51, which is likewise raised and lowered by means of a roller 52 and a cam disk 53. When the pasteboard strip is lying on the bar =l6 the latter rises and, presses the pasteboard strip against a stationary bar 54 (Fig. at). Tiien the angle bar rises and bends. up the free edge of the paper strip. Now abar or-second folder 59 advances and folds the rising edges of the paper strip over onto the pasteboard strip (Fig. 5). The bar 59 is pivotally fitted by a broad arm 60 to the lever 61, on which a roller is fit-ted, which rides on the cam disk The arm 69 has two extensions 64;, to the ends of which a rod 65 is hinged, which projects through an eye on the lever 61, and on which I a spring .66 is fitted. .Thelower endo'f the band, a pair of feed rollers, a feeler interrod 65 bears on a cam disk 67. First the bar 46.'

' pasteboard strip and hold the same during bar 59 is, swung forward by means of lever 61 and cam disk 63, wherebythe edge-of the paper strip is folded over. Then, at its further advance the'bar is lowered by means of rod 65 and the cam disk 67, so that it presses the paper strip against the upper side of the pasteboard strip (Fig. 5). When the bar-539- has receded and the bar .46 has been lowered a little, a gripper 68 advances,

grips the front edge of the pasteboardstrip and it with the paper strip from the paper strip is thereby unwound from the roii 5'6. 1 Then a shears 69 closes by its blades being operated by the rods 70 and the lever *4" On the bar '54 a pin 72 is fitted vertically displaceable, which is depressed by a spring 73. This pin is' held in lifted position by the upper blade of the shears, but when this blade is lowered for cutting,"also the pin 72 will sink onto the the cutting operation. The pasteboard strip on which the paper strip has been pasted is then taken by the gripper to the known box.

making machine.

I claim:

1., In :1 box-making machine, a paper-strip feeding band, means for operating said posed between said rollers, means actuated by the feeler'. for arresting the band operating means, a table adapted to receive the paper strip, a bar, a slide for shifting the strip from the table to the bar, means" for feeding a second paper strip to the bar,

means for mming said second strip, and means for oldmg said second strip around one edge of the first named strip.

2.- In a box-making machine, a paper strip feeding band, means for actuating said band, walls between which the strip is adapted to'enter, a bar, means for advancing said strip onto said bar, means for feeding a second paper strip to the bar, means for gumniing said second strip, means for lifting the bar, avertically movable folderlocated 'sidewise of the barfand adapted to turn fsecond strip, means for folding the second strip around one edge of the first named strip to form a compound strip, grippers for drawing the compound strip off said bar,

shears for cutting the compound strip and means for holding the compound strip during the cutting operation.
