i v Rochester, New York, have invented certain new and useful Improvements in Packaging- Machines, of which the following is a specification.

This invention relates to improvements in packaging machines.

The main objects of this invention are, first, to provide an improved packaging machine by which articles of the character of shredded wheat biscuits or other articles of a more or less friable nature may be effectively packed without injury thereto. Seclond, to provide an improved packaging machine which is automatic in its operations and of large capacity. Third, to provide in a structure of the class described, improved carton feeding means. Fourth, to provide in a structure of the class described, an improved means for filling and discharging the filled cartons. Fourth, to provide an apparatus of the class described, which is comparatively simple in structure and not likely to get out of repair.

Further objects, and `objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the folloiving specification.

The invention is clearly defined and pointed out in the claims.

A struc-ture which is a preferred embodiment of my inventio-n is clearly illustrated in the accompanying drawing forming a part of this specification, in which:

In the drawing similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at. the ends of the section lines.

Referring to the drawing, the frame lis shown mainly in conventional form and may be of any desired construction to properly support the parts and their driving connections.

The driving shaft 2 is driven by the pulley 3 and the driving belt 4. The articles to be packaged are conveyed to the machine on trays 5 by the conveyer or feed belt. 6. The trays are. returned or discharged from the machine by the conveyer 7. The empty cartons` are carried into the machine by the conveyers 8 while the filled cartons are carried from or discharged from the machine by the conveyer 9. The outer ends of these conveyors are not illustra-ted as the means for delivering the filled trays to the conveyors 6 or the unsealed cartons to the conveyers 8 or for handling the filled cartons form no part of this invention. In practice, the filled cartons are preferably delivered to theiconveyers 8 from a suitable bottom sealer and v from the conveyer 9 to a top sealer.

The conveyer 6 is driven by the shaft 10' provided With a suitable roller or pulley 11. The shaft 10 is connected by the gears 12 and 13 to a shaft 14. The shaft 14 is connected by the sprocket-chain 15 to a shaft 16 disposed toward the bottom of the frame. The shaft 16 is connected by the sprocket chain 17 to a sha-ft 18 extending across the frame. The shaft 18 is in turn connected on the opposite side of the machine by the sprocket' chain 19 to the driving shaft 2. The severa-l sprocket Wheels are not designated by numerals as their. arrangement Will be readily understood. Other parts are driven through this connection as Will appear as the description proceeds.

The trays -5 are provided With flanges 20 on their longitudinal edges. The trays are delivered from the feed conveyer 6 onto the table 21 by a mechanism consisting of the sprocket chains 22 having flight-like pusher bars 23 mounted thereon. The sprocket chains 22 are supported to travel above and parallel with the inner end of the conveyer 6 by means ofsprocket Wheels 24 and 25 carried by a sha-ft 26 and the shaft 14 respectively, the sprockets 25 being the driv? ing sprockets. As the flights or pushers 23 are carried along by the sprocket chains, they engage the rear ends of the trays 5 and push them fromI the inner end of the conveyer 61 onto the table 21. As the trays are pushed onto this table, the biscuits or other artic-les to be packaged, carried by the trays, are, picked up by the scoop or pick-up 27 which is disposed above the table and in proper spaced relation thereto, so that the tray passes under the scoo-p and the articles onto it. The structure illustrated, is del signed for simultaneously filling tivo series of cartons. 4

The scoop is provided with diverging chutes 28 at its rear end. See Figs. II, 1V, and V. The scop is flanged at its edges to retain and guide the articles thereon. The structure illustrated, is especially designed for the packaging of shredded cereal biscuits which are placed on the trays in two rows.

. The trays are in practice preferably baking trays so that the biscuits are packaged direct from the ovens Without handling. The

l flange 29 at one side.

flights or pushers 23 engaging the rear. ends of the trays, serve to support the biscuits as well as to carry the trays along so that the biscuits are delivered onto the scoop as described.

The table 21 is provided with a guide This table 21 is pivoted at 30 and is supported in its operative position by means of the link y31 mounted on the slide 32. This slide 32 travels in the vertical slide-Way 33 as shown in Fig. V.

As the structural details of this slide and slide-Way are not a part of this invention they are not here shown. The slide 32 is provided with a roller 34 traveling on the cam 35 on the shaftl 1G. As the cam revolves, the ro-ller 34 drops into the low point 3 6 of the cam, allowing the table to tilt or swing down on its pivot, discharging the provided with a double series of four holders each. Y

The arms 38 carrying the holders, are connected by brac-es 40. See Fig. I. The shaft 39 is driven intermittently through a Geneva stop gear 41 on the shaft 39 and the coacting gear 42 and arm 43 on the shaft 44. The shaft 44 is connected by the sprocket chain 45 to the shaft 16 which is driven through the connections'previously pointed out. its the details of the driving connections for the shaft 44 to the holder carrying shaft 39 do not form a part of this present invention, I do not describe the same with further detail herein, 'the object of this type of driving connection being to drive the shaft 39 with a step by step movement properly timed to bring the holders 37 into position to receive the articles as they are delivered from the chutes 28.

The articles are delivered from the chutes 28 into the holders by the packers 4G supported on the arms 47 on the rock shaft 4S extending across the frame above the chutes. The packers 4G are .actuated from the cams 49 onthe shaft 14. The cams 49 act upon the reciprocating rods 50 supported in suitable bearings in the brackets 51. The rods 50 are connected to levers on the shaft 53, the levers being connected by the links 54 to the arms 47 of the pac-kers. The ca1ns`49 are provided with a plurality of cam projections 55, (see Fig. VI), there being twelvev of these projections on the cams of structure illustrated, so that each package contains twelve articles. The rods 50 are provided with rollers 56 traveling on the cams.

To support the articles in proper position as they are being packed in the holders 37, and also to eject them 4into the cartons and the cartons from the holders, I provide the holders' with plungers 57 supported by the stems 58 reciprocating in suitable sleeves 59 Within the -holder carrying arms 38. The plungers are yieldingly supported yby the coiled springs G0 arranged within ythe sleeves. The plungers are provided with racks 61 with which the pawls 62 coact. See

Fig. XV. These pawls (S2 are provided with actuating' springs G3. As the articles are packed into the holders by the packers 46, the plungers are forced inwardly against the tension of the springs GO and are retained by the pawls until released by the pawl tripsI (il which are positioned to act after the cartons have been slipped over the holders so that the articles are delivered into the cartons. This step ir. the cycle of operations of the machine will be again referred to in its proper sequence.

The shaft 89, is, as stated, actuated with a step by step movement, each step being a quarter revolution of the shaft. From the filling position, the holders are actuated to a vertical position to receive the cartons G5 which are slipped over the holders.

The cartons are, as stated, conveyed to the machine by the conveyers 8, the cartons being arranged on the conveyers on their sides with their open ends facing inwardly. The conveyers 8 are driven through the sprocket chains 131 connecting them to the shaft 2. The cartons are carried by the conveyers 8 against the sto-ps G6.- From these conveyers 8, the cartons G5 arel delivered or shifted onto the feed table 67 which projects forwardly so that the holders 37 swing under its forward end when they are brought to the vertical position from .their filling position.

The carton shifter members (38 are provided with fixed fingers 69 at their outer ends adapted to engage the outer ends of the cartons and pivoted plate-like clamping lingers 70 adapted to engage opposite sides thereof. The clamping fingers or plates 70 are mounted on the pivots 71 on the arm 72 on the member 68. Springs 73 support the clamping fingers 70. The member 68 is arranged upon a spindle 74 carried by an oscillating member 75 mounted on the shaft 76. The oscillating member 75 is provided with a segment 77 which is actuated by the rack 78 arranged in a vertically disposed slide bearing member 7 9, see Fig. IX. The rack 78 is connected by the link 8O to the lever 81 mounted on the shaft 81 extending transversely across the frame. actuated by the cam 82 on the shaft83. This shaft 83 is connected by the sprocketchain 84 to the shaft`85 which isconnected by the gears 86 and 87 to the driving shaft 2, the sprocket chain being arranged on one side of the frame and the gears on the opposite. This driving connection for the oscillating member 75 swings it from a horizontal position shown by dotted lines in Fig. IX, to the vertical position shown therein.

To rock the member 68 from its carton engaging orl picking up position as shown by dotted lines in Fig. IX, to its delivery position, as shown by full lines, it is provided The lever 81 is with a segmental gear .88 coacting with a fixed segmental rack 89. It will be obvious that with the segment S8 in engagement with the rack, when the member is swung from its vertical to its horizontal position or vice versa, itis oscillated. The cartons are inverted by this shifter and carried into position to be delivered onto the table 07. To effectively deliver the cartons to the table the flaps 90 thereof are spread out to a horizontal position, as shown in Fig. IX. The fiap spreading or opening fingers 91 are pivoted at 92 on the vertically adjustable member 98. This member 98 is mounted for vertical movement in the bracket 93. The member 98 is connected by the link 95 to the lever 96 mounted on the shaft 81, the lever being actuated by a cam 97 on the shaft 83. The member 98 is connected to the link 93 by means of the clip 99 on the lower end of member 98. To spread and collapse the fingers, the inwardly projecting arms 100 thereof are connected to the rod 101 reciprocating in the member 98. See Fig. XI. The arms 100 are slotted at 102 to engage pins 103 on the reciprocating rod 101. The rod 101 is connected by the link 101 to the lever 105 on the shaft 81 actuated by the cam 106 on the shaft 83. By thus arranging the parts, the spreader is first actuated to carry the spreader fingers up within the flaps by the upward movement of the member 98 which is accomplished through the connection described. The fingers are then spread by the upward movement of the rod 101 which is accomplished through its connection described, the.` movements being properly timed through their driving connections. The cartons are` pushed from this position shown in Fig. XII, that is, after the tiaps have been spread or bent to a horizontal position onto the table '67. The feed members 107 by which this is accomplished are carried by the slides 108 arranged in suitable ways 109 provided therefor in the table. See Figs. XII, XIII, and XIV. These slides 108 are provided with racks 110 on their under sides, which are, driven through the pinions 111 on the shaft 112 arranged below the table. The shaft 112 is driven through the train of gears 113, 114, 115, and the oscillating segment 116 .which meshes with'the gear 115. The segment 116 is pivoted at. 117 on shaft 81. The segment is provided with an arm 118 having a roller 119 thereon traveling on the cam 120. The table 67 is rovided with guides 121 for the cartons, tiie guides being supported on overhanging arms 122 so that the lower edges of the guides 121 are spaced from the table to permit the flaps to project under the guides. The table 67 is provided with openings 123 at its forward end to which the cartons, are delivered through the holders 37.

I have described only one shifter mechanism,y one yflap spreader mechanism, and one carton feeder, as the other is a duplicate mechanism. The operating connections for the shifter and flap spreader mechanism are duplicate. The two feed or pusher members 10T are actuated through the single cam 120.

The cartons are supported in position above the openings 122 in the feed table by their flaps. From this position, they are pushed through thebpening and over the holders 37 by the members 124 mounted to 4 `reciprocate on the vertical rods 125 carried by the table 67.

The delivery members 124 are connected by the links 126 to the levers 127 mounted on the transverse shaft 128. These levers are in turn connected by the links 129 to the bent levers 130 mounted on the transverse shaft 131. The bent levers 130 are actuated from the cams 132 acting on the rods 133 arranged to reciprocate in suitable bearings in the brackets 51. The springs-134 on the rods 50 return the packer fingers. The

springs 134 on the rods 133 return the plungers to their initial position. As stated; the holders 3T are swung under the openings 122 in the feed table in which position the cartons are pushed over the holders by the members 124. The cartons are then carried by the holders around to the lower position above the delivery conveyer 9 in which position, thel trips 64 act upon the pawls 63 releasing the plungers 57 so that the articles in the holders are pushed out or ejected into the cartons which are simultaneously pushed off thev holders and onto the conveyer 9. The next actuation brings the lemptied holder into position to receive the articles. This completes the cycle of movements of the machine; which I are the delivery of articles to be packaged on suitable trays as,

5 on the conveyer 6; the transfer of the trays A from the conveyer 6 onto the table 21 during which time the articles are picked up from the trays by the scoop 27 and pushed along thereon up the chutes 28 to the packers 46; the discharge of the empty trays from the table 2l onto 'the return conveyer 7;

the delivery of the empty cartons on the,

v injury thereto.
