This is accomplishe by placcarried toward the opposite end thereof. ing three rows of four cans each in position For the purpose of guiding the cans as as will be later described.

' they are carried upon the conveyer belt, side As shown in Fig. 1, four cans are located 106 rails 10 may b9 aa d upon each Side of upon the conveyer belt over the bed plate 6 and beyond the stop finger 1Q. Until these cans have been moved laterally, upon the tilting table 30, into the position of the 'ro'wl of cans indicated at B, the remaining cans upon the conveyer belt are held against movement by the sliding stop bar 12'.

In order to move each' row of four cans laterally from the conveyor belt onto the tilting table, a reciprocating frame 31'is provided having the angularfouter end-32 andthe rearwardly disposed arm 33 at its inner end, said arm having the reduced or notched extremity '34 adapted to be engaged by the hook 21 of therod as will be later described.

-This frame is provided with a pair of spaced rearwardly extending guide rods 35 mounted for reciprocation through thebearings .36 upon the bed plate. 6. These guide rods are connected together at their rear extremities bvthe bar 37, to the central por-' tion of 'wiich is pivotally connected the upper end of. a lever 38, fulcrumed at its lower end as at 39iupon ,a' link 40 pivotally of the reciprocating frame connected as at 41 to a brace bar 42-mounted upon the .side frames 1 and 2'. I A; cam 43 is fixed upon the shaft 44, jour- "naledin bearings 45 carried by the side frames. The lever 38 is normally held-in contact with the periphery of the cam by means of a spring 46.

A pulley 47 is mounted'upon the cam shaft 44and maybe driven from any suit-.- able source of power as by the belt 48. As, the cam shaft is thus continuously rotated the reciprocating frame 31 will normally be continuously reclproeated.

For the purpose of stoppin reci 'rocation when t e tilting table. 30 has been filled with cans,'a stop finger49 is provided upon the lever 38 for engagement with the stop lug 50 upon the cross bar 51. This stop finger 49 is nor,- mally held out of engagement with the stop lug 50 by means of the bellcrank 52 pivoted as at 53 upon the cross bar- 51.

The depending arm 54 of the bell crank lever is provided with theinclined lower end 55 arranged to be normally engaged-by the curved pin 56- carried by the lever 57. This lever ispivoted near its inner end as at 58 to a bar 59 connected to the cross braces 60 of the side frame 2. The-outer end of this lever is connected to a link 61 pivotally connected toa depending post 62 unpn the inner end portion of. the tilting I normally held inhorizontal position by the This table is hinged to the side frames 1 and 2, substantially at its longitudinal center as indicated at 63 and arranged to be spring 64 connected to the outer end of the lever 57 and to the lower portion of one of the legs of the side frame 2 An air cylinder 65 may be pivotally consto n elongated pin'88 is connected to the nected at its. lower end to one of the cross pieces 60, asindicated at 66,*the'piston 67 thereof being pivotally' connected to the lever 57 as shown at 68 in order to cushion the downward movement of the lever 57.

A short lever- 69 is pivoted at its outer end to the inner "portion of the lever 57 as p T shownat 70. This lever is normally held down in engagement with the cam 71, upon the camshaft 44, by means of the spring 72 which is connected to a pin 73 upon the under side of the lever 69 and to an elongated pin 74 depending from the inner end "of the lever 57.

The stop mechanism above described is designed for holding the reciprocating frame against movement during the time the" table 30' is tilted to remove the filledcarton. For the parpose of automatically.

stopping the movement of the reciprocating frame as soon as-the proper number of cans, to fill a carton, are placed upon the tilting table, a'stop mechanism is provided comprising a bent lever 75. pivoted intermediate its ends, as at 76 to the side frame 1 and adapted to be rocked by means of the sliding bar 77 mounted for reciprocation beneath the ti'ltingtable 30. This bar may beprovided with the elongated slots 78 which receive the bolts 79 protruding from portion of the bent lever 75, whereby an outward pull upon the bar 77 will rock the lever upon its pivotal point 76.

The inner end portion of the lever 75 may be slidably supported upon the supporting bar 85, and pivotally mounted upon the inner extremity of said levcr as at 86 is the lever 87 inner end of the stoplever and a'pull spring 89 is connected to the extremity of said pin' and to the'lever 75 as'shown at 90.

v A pull spring 91' is connected to the outer 7 end portion of the lever 87 at one end, the" other extremity of the spring being connect-g ed to the side frame 1 as'shown at 92, tending to normally hold sition shown in Fig.3.

With the partsin the normal position, as shown in Fig. 3, it'will be seenthat the stop lever 87 is normally held out of the path of the rocklever 38 which operates the reciprocating frame 31, 'and the ivoted stop finger a uponv as we a a am a? the lever 87 in the po- I stop lug 50 by means of the bell crank52,

In the operation of the apparatus, the cans, or other articles to be packed, aremoved upon the conveyer belt 4 in the direction of 1. The sliding stop bar 12 is in theposition shown in this figure and the first can is stopped by-the same in the position shown atA. 5 1

The next three cans to passalong the belt shown at A. The fifth can, shown at C, will engage the setting lever 28 and move itfrom otted line position to thefull line position shown in Fig. 1'.

This movement of the settin lever will,

through-the link 29, move the re easing lever 21 from the dotted line to the full line posithe conveyer tion, permitting the next can following upon to engage the releasing lever and move the same still further, sliding the rod 20 throu n the 100 19 and moving the hook 21 into t e path 0 the angular notched end34 of the reciprocatin frame.

Upon the next rearwar movement of the reciprocating frame, the hooked end 21 of the rod 20 is engaged by the notched end of the frame and the sliding stop bar 12 is I pulled rearward "out of the path of the cans.

Aand A are then The four cans shown at moved over the bed plate into the position shown at D.

Upon the next forward movement of the. reciprocating frame 31, these four cans are osition shown at e tilting table 30.

This operation is continued until three rows of four cans have been placed upon the tilting table, each succeeding row of cans pushing the next preceding row forward upon the table.
