The plate is fiized to a slide or bridge 26slidabl mounted at its end's on'parallel horizon al' guide bars27 fixedto short'standards The slide 26is' connected to'ja lever 29 by a link 30 and said lever is fulcrumed. on shaftf'33 pivotedftiubrackets 234 and 235 and is formed withla longitudinal slot 31 engaged by a pin32, projecting from the reciprocating bar 10.

As the rod moves backwardly in'the directionof the arrow in Fig. 3 the pin 32 moves the lever 29 in the same direction and causes the tapered end 24 of plate to' engage the adjacent flap .17 ofa carton and cause it to turn into the position shown by the preceding flap'in ]5ig'."3' When'the' cartons are placed in'the 'poelretsfthe flaps do not lie flat, but'are flared outwardly at an angle so that'as plate ,23 moves backward the end 24 gets undefthe flap" ."17 'a'nd engagesv it and turns it o'verto' approximately the opposite angle, it being so maintained While the car' ton is passing-under the plate.

Thus when the plate 23. moves inthe'direction. of the carrier .the plate by reason of its lever moves quicker than the carrier and its edge 25 engages the lap 17 and turns it back flat and by the ad vancement of the carrier this flap and like- BEST AVAlLABLE COP;

wise in succession the flaps 19, 20 and 18 are transferred from under plate 23 to beneath the projecting end 83 of the plate 34 fixed to standards 35 on the base plate B. The end 83 is upwardly inclined and dished as at 61 (Fig. 3) in its centre and the slide 26 is correspondingly:dished as at 62 (Fig. 1).

The plate 34 is curved correspondingly to the curve of the carrier around sprocket 5 and it separates the carrier from a circumfe'rentially arranged series of superposed measuring pockets 135 (Figs. 1 and 6). These pockets, which are open at each end, are fixed to the flange 104, Fig. 4, of a circular plate" 105 fixed on spindle 7 and covered by a plate or cover 36 formed with openings 37 coincident with two pockets 135. Above the plate 36 is a hopper 38 into which the material-is fed, preferably capable of fillin-g two measuring pockets 135 at a time said pockets being closed at the bottom by the curved plate 34.

As the measuring pockets 135 advance at the same rate as the carton carrier, the bottom edge' of the hopper trims the material across the top edge of said pockets so that each pocket contains the same quantity of material.

In order to prevent a choke of the material in the hopper 38 and ensure its feed by gravity into the measuring pockets said hopper is pivoted at one end upon a standard 39 on the base plate and projecting arm 40 on the other end of the hopper is provided with a roller 41 engaging a cam 42 rotatable on a spindle 43 and driven by pulley 44 belt 45 and pulley 46 on the main shaft 14. I

'The cam is formed with a Wavy edged groove that imparts a horizontal vibratory motion to the roller 41 and consequently to the hopper which ensures delivery of material therefrom into the measure pockets.

At a further advanced point the station-- ary plate 34 is formed with a rectangular opening 47 through which a measure pocket 135 transfers its contents into a co-incident carton C while the carrier is momentarily stationary.

In order to ensure complete discharge a vertical plunger 48 isprovided, Figs. 1, 2 and 6, the shank of which is mounted on an arm 49 projecting from a verticalreciproeating rod'50- journalled in a bracket 51 on the baseplate and guided at its lower end in a vertical guide 52 and a side plate 53. The rod Fig. 5 is connected by a pin 54 witha slot 55 of a lever 56 pivoted at 57 on a bracket 58 and provided with a roller 59 engaging a cam 60, on the main shaft. Vertical reciprocation of the plunger 48 completely through the measuring pocket and the opening 47 ensures the entire contents of the pocket being delivered to the carton beneath.

In order to ensure correct registration of block '65,, Fig. 6 engaged by the bifurcated end of'alever 66 f'ulcrumed at 67 on bracket 68"sup-ported'by a's r'in 69 said lever hav- 'ing"a-roller 70 engaging'a cam 71 on the maiasnan "14.

The stop 63 rises'throug'h slot 64 in front of'thepocket? of the carrier containing the carton receiving the contents of a, measure pocket and ensures registration of the sides of the ine'asemjand carton pockets. "The inner upper end. 72of the stop is preferably beve'lled'prslightlycurved ('s'eeFig. 7) and "engages the *link 1 in front offsaid stop'if "same should be extending outwardly and'so pushes it back "with the object of ensuring exact'registrati'onof front'and rear sides of the carrier pockets with the corresponding sides of them'e'asure jpockets.

Upon thero'd' 5 0 is another arm 73 supporting the shank of a rectangular cleaning brush 74 that r'e'ciprooates vertically in each measure pocket in succession and discharges any material remaining in said 'pockets'into a receptacle! 5, Figs, 1 and 5.

The mechanism for closing down the fiaps of the filled cartons'as"shown in Figs. '1 and 6 forms the subject matter of my divisional application Serial No. 739,226 filed Sept. 22,1924, and comprises a fixed narrow overhead longitudinal plate 76 mounted on a bridge fitted to'standards 77 and a horizontally reciprocatingfingeror folder 78. The latter'operates'in guides 82on-plate 34 and is pivoted on an arm 79 pivoted on a vertical lever 110 on the rock shaft 33 which latter at an end has an arm 80 formed with a lateral slot 81 engaged by the pin 32 on the reciprocating rod or bar 10.

As the carton advances the end of plate 7 6 engages the flap 17 and turns it inwardly to an angle approximately 30 degrees to the horizontal, then the folder 78 advances and its end engages flap 18 and turns it into horizontal position. WVhen the carton continues, plate 76 presses flap 17 down over flap l8 and the other flaps 19 and 20 are engaged respectively by overhead inclined arms 84, Fig. 1, which arms converge and the arm 84 is bent to complete its folding operation before arm 85 functions sothat the peaked flap 20 is the one overlying the other three flaps.

The final operation being the depression of the flap 19 with the slit 22 and the peaked flap 20 to finally lock the peak in the slit. This operation is performed by a downwardly bent finger 86, Figs. 8, 9, and 10 on an arm 87 pivoted on standards 89 and connected to a vertical rod 88 spring controlled SEST AVAlLABLE CQPY and'connected with an ajgiproximately horizontal arm 90'having "a roller 91 engaging cam 92 on the shaft 14. I

The pointof the finger 86 in depressing the slitted flap and the peaked flap moves towards the inner side as in '9 and l0 and in'doing so its peak 'i's'flipped over "the outer edge 112 of the slit 22 and intothe latter so that when the finger rises" the cal:

ofthe flap 20 progresses further in to's aid slit and so securely closes the filled carton. During this action'thefront and'lrear sides of the cartons are momentarily-pressed outwardly, such movement being permitted by 'a roller engaging a cam 101on'the'main shaft. The cartons discharged through opening'92 are delivered into a chute "102 leading to the'pa'c kers.

It will be seen from the'foregoing'thatthe cartons having flap closure pieces are fed by hand to the pockets P on'carrier 21the flap pieces laid flat at plate 23'position (Fig. 1) and maintained fiat until the cartons are filled at plunger 48 position then closed by plates 76 'and 78 and levers 84 and 85 and finally by finger '87.

Further the granular ,material passes from the vibratory hopper 38 to the circumferentially arranged measure pockets 135 which latter when filled register with and empty into the cartons in succession.

Finally the filler and closed cartons are ejected from the pockets P by the plunger 98.
