To all whom it may concern: 1

Be it known that we, ERNEST A. Sermon- :DER and JonN- N. TOOKER, citizens of the of which the following is a specification.

The object of this invention is to provide a machine having novel IIIGCllEtIllSIIlS for supplying collapsed cartons and for feeding the v collapsed cartons one by one to a predetermined point for subsequent operations thereon. s

The invention consists in certain improvements in the construction, form and arrangement of the several parts of a carton handling machine whereby the above object may be carried out in a simple, rapid and effective manner.

The invention more specifically comprises an endless carrier arranged to feed thecollapsed cartons upwardly along a a carton supply magazine into position to be fed into the machine, and means for feeding in the collapsed cartons.

A practical embodiment of this invention is represented in the accompanying drawings, in which Figure 1 is a top plan view of a carton handling machine embodying our invention,

Fig. 2 is a vertical central section taken from front to rear through the machine with the severalparts in the positions which they assume when the carton feeding and opening mechanism is at the limit of its forward movement,

Fig. 3 is a continuation of Fig. 2 from the indicated broken line to the floor line,

Fig. 4 is a detail section showing the means for controlling the movement of the feeding mechanism for the collapsed cartons,

and

Fig. 5 is a detail view corresponding to Fig. 2, with the parts in the positions which they assume when the carton feeding and opening mechanism is at the limit of its rearward movement.

The cartonsupply mechanism will be first described. A vertically arranged magazine .17 is provided for the collapsed cartons. An

endless carrier is provided for moving the stack of collapsed cartons upwardly along the magazlne 17 to bring the uppermost carton into position to be fed into the machine, which endless carrier comprises side chalns 18 passing around upper and lower sprockets 19, 20, on cross shafts 21, 22,

which chains are provided with shelves 23 arranged to be brought into their supporting position while passing upwardly along the supply magazine 17, by means of studs or rollers 24, arranged to travel along a vertically arranged cam 25. An intermittent movement is provided for the endless carrier by means of a ratchet wheel 26 engaged by a pawl 27 on a bar 28 provided with an eccentric connection 29 with the auxiliary drive shaft 14; the shaft 30 of the ratchet wheel 26 being connected to the upper shaft 21 of the endless carrier through a chain and s rocket connection 31, 32.

The pawl 27 is rendered inoperative when the, stack of collapsed cartons reaches the predetermined height with reference to the feeding-in table 34 by the following device: The pawl 27 is providedwith a bracket35 which is connected to a rock arm' 36 by a rod 37, which rock arm 36 is fixed to a rock shaft 38 mounted in suitable bearings on the machine frame This rock shaft 38 has fast thereon a rock lever 39 having a carton engaging device comprising a crossbar 40 and depending arms 41 arranged to engage the top of thestack of collapsed cartons. ,A spring 42 and stop pin 43 yieldingly hold the depending arms 41 at the limit of their downward movement. This rock lever 39 is also provided with a roller 44 arranged to engage the upper combined feeding-in and opening-up suction nozzle, to lift the arms 41 from their engagement with the top of the stack of collapsed cartonswhen the said nozzle is at the limit of its forward movement, as will hereinafter more fully appear.

The suction means for feeding in and opening upthe collapsed cartons is constructed, arranged and operated as follows: The upper suction nozzle 45 is provided with a feeding-in mouth 46 at its front end and a carton opening-up mouth 47 ,at its rear'end, saidm'ouths opening through the bottom 48 of the nozzle. The upper nozzle is also provided with a downwardly and forwardly inclined top 49 arranged to en-r gage the roller 44 on the rock lever 39. This upper nozzle 45 has a carriage 50 which reciprocates horizontally'in a right line in guides 51 in the side l'ral'nes of the machine.

This 11 er nozzle is connected throu h a v i b flexible pipe 52 to any suitable anexhaust ing means, not s hown herein; 7 I I The lower nozzle 53 has an opening-up mouth 54 arranged to coact'with'the opening-up mouth 47 of the upper nozzle 45. This lower nozzle has avertically reciprocat- "ing movement in a carriage 55 which reciprocates horizontally in aright line parallel with the carriage-5O insuitable guides 56.

The, nozzle is provided with a cross pin 57 projecting through its side walls and through vertically elongated slots '58 in the carriage'55, which cross pin is provided with rollers 59 traveling in cam' grooves 60. These cam grooves 60' are horizontally arranged fora portion oftheir length from the rear'toward the front and are then di- "rected upwardly and forwardly to cause the the upper nozzle as the two nozzles approach lower nozzle to approach andrecede from I andrecedefrom'the forward limits of their movements.

The 'reciprocatory movements of the upperandlower nozzles are under the control of a rock lever 61 pivoted'at62 near the base of themachine, which rock lever is engaged byan' eccentric cam 63 on the auxiliary drive shaft '14, A rod 64 isconnected at 65 to the'upper nozzle carriage and at 66 g tothe upper end of the rock lever 61; A

rod 67 is connectedat 68 to the lower nozzle carriage and'atits rearend has a loose sliding engagement in th'e arms'69, 70, of a bracket 71 pivoted at 72 to the lever 61.

A lost motion connection, between the lower nozzle carriage and the rock lever 61, is provided for as'follows: 'A stop 73 is fixed to the rod 67, which stop is provided with rear and front shoulders 74, 75, ar-

. rangedinposition to be engaged by Van'arm T 6 depending from the rod 64 at the rear end .thereof. This stop 7 3 is furthermore pro I half of their rearward travel; the remainder oftheir rearward travel inthis position being LC CO HIPll'Sll Gd by the engagement of 0 the, arm 7 6 with the rear shoulder 74 of the stop 7 3. I

" While the mouths 47 54, of theupper and lowersuction nozzles are coacting to open up a carton, the mouth46 of the upper nozzle will be feeding the next succeeding colately resume itsioperative position when the rier. As the upper suction nozzle 45 reaches the limit of its forward movement, its mouth 46 willvengage the topmostcarton -bysuccatch: at, the limit of the rearward movement lapsed carton from the stack rearwardly along the feed table 34 into a position im the corners of the cartons pass while opening and traveling with the movements, the mouth 54 of the lower nozzle is permitted a slight rearward movement against the tension of a spring 81, which spring 81 will return the mouth 54 to its normal position in alinement witlr. the lower nozzle, This month 54 is furthermore provided with a spring-actuated stop 82 along its rear edge, which stop projects above the lower nozzle a sufiicient distance to engage the rear lower edge of the carton to prevent the carton from overrunning the mouth of the lower nozzle. When the opened-up carton isremovedfrom between the opening-up mouths of the upper'and lower suction nozzles, the stop 82 will be forced below the upper plane of the lower nozzle but will immedicarton has passed rearwardly beyond it.

The lower suction nozzle is connected to the exhaust pipe 52 through the pipe 83, it being, understood that there is a constant suction exerted through the upper and lower suction-nozzles at all times,

The collapsed cartons are fed upwardly along the carton supply magazine 17 by the intermittent movement of the endless cartion effect and the carton will be carried overthe table34 past the fingers 79 of the a of the suction nozzle 45. The-finger 79 en- Y gages the collapsed: carton and holds it on the table 84 until the mouth 47, inturn engages it at. the limitof the next forward movement. In the meantime,.- the suction 'mouths'47 and 54 of the :upper 'and lower nozzles are causedto engage-the upper and lower sides of the previously fed-incarton and move the same inwardly, and, at the sametime, opens up the carton.

It will be also be; understood that if the collapsed cartons are-being fed too rapidly upwardly along their magazine 17, the feeding of the cartons will be temporarily stopped by the coaction of the topmost carton with the arms 41' of the releasing device.

It will also be seen that. these arms 41 are raised from their position onlthe top of the stack of collapsed cartons, by the engagement of the upper suction nozzle with the roller 44 at the time the suction nozzle isengaging the uppermost collapsed carton for feeding the same intothe machine.

The mechanismsshown anddescribed but not claimed herein, form the subject matter of our United States Letters Patent No. 1220566, dated March 27, 1917, of which this is a division.

What we claim is:

1. In a machine of the character described, a collapsed carton supply magazine, an endless carrier for feeding the cartons upwardly along the magazine into their feeding-in position, feeding-in means for the cartons and means adapted to be engaged either by the carton stack or the feeding-in means for arresting the movement of the carrier.

2. In a machine of the character described, a collapsed carton supply magazine, an intermittently moving endless carrier for feeding the cartons upwardly along the magazine into their feeding-in position, feeding-in means for the cartons and means adapted to be engaged either by the carton stack or the feeding-in means for arresting the movement of the carrier.

In testimony that we claim the foregoing as our invention, we have signed our names this 21st day of February, 1916.
