for such machines, an improved, automatical- 1y operative carton or container feeding magazine for properly presenting the collapsed cartons tobe opened. and filled, and

having, among others, the ad-vantagesherein s t r U l/Vhile our novel device; is adapted for use with machines of varying construction, the particular embodiment thereof herein described and illustrated isiespecially designed for use with such amachine asthat which is the subject of an application for patentby John D. Lane, Serial N0 6 613,401, comprising a long base or bed plate over whichthe car-tons are conveyed by anen dless conveyor while the desiredvarious steps are performed on the carton by ppropriate instrumentalities. Referring to the drawings, I Fig.1isaplan; I Fig. 2, a partial elevation from the right of Fig. 1;

Fig. 3, a similar View from the left of 1; a Fig. 4, a verticalcross-section on 44, Fig. 1, from the left; Fig. 5,. a vertical cross-section on the 5-5, Fig. 1, from'th'e left; v

Referring first to Figs. 1', 2, our novel construction comprises a suitable support as a braclzet 1, adapted to be secured, as by bolts 2, to some convenient part of the frame or base the line line plate 3,21 portion only 'ofwhich is shown, of V a packaging machine. used with the machine above referred to, this construction would be secured to it at right angles tothe length of abed plate andqadj'acent the cartonf opening blade.

The bracket 1', Fig. ,5, has secured to its upper end by bolts an inverted U-shaped supporting bar 5,. Thebar 5 carries on its top a cross bar 6 whichsupports on each end a shortfrail 7. fora wheel 8 which supportsone side plate 9 of the carriage of themagazine,

the construction being similar on the opposite or outer end of the magazine, not shown. The side plates 9, Figsi2, 3, of the magazine, carry side bars 10, one on each .side,secured to them as by bolts l1, which side bars extend thelength of the magazine and they are connected at their opposite ends by any suitable means, and rest on any convenient support as a post,not shown.

The side plates9, Figs. l, 8 5, are connected at the, Fig. 1, right hand end of'the magazine adjacent thepackaging nachine, by a horizontal plate 13,-jwhichforms a bottom and carton supporting member for the magazine.- The side plates '9, Figs l, 5, carry be tween. them near theirbottom edges and throijlgh-suitable bearings a quill-or hollow shaft 14' on .which adjacent to andb'etween the members 9. are sprocket wheels 15,. over which, Figs. 1, 6, run chains 16Jforming an endless cart-on carrier and feedeiy'and which are supported at their opposite or outer ends, not shown, by similar sprockets to those shown in Fig. 5;} The chains, Fig, 4, run along upper channel supporting memberslS andspool like lowerzsiqpports 19,and' motion is impartedinitially to the chainsbythe forward and backward motion of the magazine as will be presently described.

The side plates 9, Figs. 2, .3, 4, 6,. have pivoted to them as by means of a bar 22 a link 23 which, in turn, carries pivoted thereto at its opposite end a lever 24 carrying on one arm, the laterally projecting supports 19 referred :to above, and this. lever is mounted as; b'y a pin 25in the downwardly which is determined araised stop memher on the member 5, Figs. 1, 3, 6, against which the link 23 abuts when moving inwardly or to the right, Fig. 2.

For transmitting motion from the magazine to the carton carrier, we provide, Figs. 3, 5, upon a shaft 29 within the hollow shaft 14 and adjacent one side plate 9, a hub 31 with a rocker arm 32 having a slot 33 and which, by means of such slot and a laterally extended bolt 34, has adjustably secured to it an upwardly projecting arm 35. This arm is adjustably connected by means of collars 36 to a slidable rod 37 having a squared end section 38 carrying an upright bar or car y ton pressure gauge 39, Figs. 3, 4, 6 and with laterally extended ends thereon, there being on the inner face of the upright bar an upright fin 40, dotted lines, Fig. 3, extended somewhat into the path of the cartons within the magazine. This member 39 thus constitutes, as will be hereafter observed, with the connections to be presently described, a carton feeding gauge which determines the regularity and speed at which the cartons are fed from the magazine to the carton opening instrumentality.

The extent of the sliding motion of this arm is determined by collars 41, 41, on the rod 37 on opposite sides of a boss 42 on the plate 9, the extent of the travel of the arm 35 being still further determined, Fig. 3 by a screw 43 in the collar 41 and adjustable therein against the boss 42.

On the same plate 9 and below the rod 37,

.3 Fig. 3, is an ear 46 through which extends a rod 47 slidable therein and within a spring 48, and carrying a carton fashioning block 49 at the end of the plate 9, the extent of the movement of this block and rod by the spring 48 being determined by positions of nuts 51 on the rod 47. The spring 48 is seated at its opposite ends against the block 49 and ear 46 respectively, and acts normally to hold the block 49 in extended position so far as the nuts 51 will permit, and the block has on its inner face also, Fig. 3, 5, a fin registering vertically with the fin 40 on the member 39. The shaft 14 carries also near its, Fig. 5, right hand end adjacent the opposite side plate 9, Fig. 2 and loosely thereon, an arm 52. Also fast on the shaft 14 and adjacent this arm, Figs. 2, 4, 5, is a ratchet wheel 53 engaged from above by a pawl 54 on the arm 52 and held in engagement therewith by a spring 55 on said arm andpawl. A rod 56 also runs longitudinally of the arm 52 to the opposite end of the magazine, not shown, for the manual manipulation of the ratchet wheel, and its connected parts including the chain carrier, when and if desired, from any convenient point.

From the member 5 just below the track 7, Fig. 2, extends outwardly a post 57 carrying pivoted at its outer end a link 58 having pivoted on its opposite end an upwardly exspring thereon and on the member 5. It will be seen that this construction is such that each time the magazine moves away from the packaging machine or to the Figs. 2, 6, left, it causes the pawl 60 to swing to the right, and as the magazine returns to the right, Figs. 2, 6, the arm 59 by means of the pawl 60 will cause the ratchet wheel 53 to rotate clockwise or toward the packaging machine from one to seven notches or within whatever limits may be provided, the number of notches representing the movement of the wheel each time, being determined by the novcl device which we will now describe.

On the same end of the shaft 29, Figs. 2, 7, already referred to, which extends through the hollow shaft 14, it carries fast thereon a tapering arm 62 which, at its outer end, has secured to it a curvilinear shield or teeth covering member 63 closely overlying the teeth and normally, Fig. 2, not beneath the end of the pawl 60.

If, however, the carton carriers 16 feed the cartons forwardly against the fins 40 on the carton pressure gauge 39 and block 49 already described, faster than the opening member opens and removes the cartons from the magazine end, the pressure created by the crowding of the cartons against the fins 40 will cause the rod 37 carrying the fin 40 to slide inwardly or to the left, Fig. 3, swinging the arm 32 likewise, and turning the shaft 29 and causing the arm 62 on its opposite end to swing to the left, Fig. 2, and project the shield 63 forwardly beneath the pawl 60. The result of this will be that when the pawl moves to engage the ratchet wheel 53, it will ride for a short distance on this shield 63 and skip some of the teeth of the wheel 53, Fig. 7, and will not on its re turn swing, engage these teeth and advance it to the normal and full extent, but will engage the first teeth available after the pawl leaves the shield.

As soon as the pressure on the fins 40 is reduced by this diminished feeding action of the cartons, the shield 63 is withdrawn to its normal position by the spring 64 on the arm 62, the shaft 29 rotated. at the same time in the same direction, and the member 39 withdrawn to its normal position, as shown in Fig. 3.

The outward or, Fig. 3, right hand movement of the magazine does not carry with it the block 49 until the car 46 on the plate 9 reaches the nuts 51 on the rod 47 and hence this results in a delayed movement of the block 49 and rod 47, and the block remains in extended position long enough to serve as a support and fashioning member for the carton While the carton opening member is engaged in opening it, and the carton is given its square, regularformation by the knife, not shown, pressing it against the block, and hence it may be said to constitute a carton squaring or fashioning member to ensure the carton being regular in shape so that it will pass regularly and without dis tortion into the carrier waiting below.

. At the, Fig. 6, left hand end of the magazine, the carrier is provided with a-follower block 65 which rests'on the chains 16 and acts, as it is fed forward by the chains, to-

press thecartons firmly together and maintain them in proper position as they approach the opening elements.

Inasmuch as one of the broad sides of each carton is partly of double thickness where the edges are lapped, such doubling will naturally result gradually in an uneven feeding of the carton to the ,opening blade', one side of the carton being slightly fart-her advanced than the other and this would sometimes act to prevent proper engagement of the blade with the carton. To correct this difficulty, the follower 65 has a post 66 thereon to which is pivoted a movable front pressure plate 67 which is free to contact with the cartons evenly across their entire face, and by which the pressure is evenly distributed against them.

The withdrawal or outward movement of the magazine is timed. by appropriate cam action, not shown, to take place just as the carton opening instrumentality has completed the opening of the carton and the latter is free to be released and carried down by the proper element therefor, to the carton carrier, not shown, and the-movement of the magazine described acts, therefore, both to facilitate the freeing of the carton from the magazine and the feeding of the cartons within the magazine through the ratchet motion already described.

T o cooperate with the fins 40 on the mem hers 39, 49, we provide on the edge of the plate'9, Fig. 2, inwardly extended pins 68 on the straps 70 secured to the side member 9 by screws or otherwise.

Manual operation of the feeding of the carrier chain 16 with its cartons may be had 7 at any time when necessary by means of the rod 56 already described through which the ratchet mechanism may be actuated at will without corresponding movement of the magazine. 7

The foregoing described'construction provides an adequate magazine, as to size, provided with an automatically adjustable feed- 7 ing means always ensuring a regular and ample supply of cartons, presented in proper condition and position for opening and suitably shaped .for further action. Our invention is not restrlcted to the pre zine and operated thereby, and feed regulating means for thefeeder also actuated by the magazine. V 3.
