(c1. 226-94) the controls for feeding the receptacles and for My invention relates to receptacle fillers for `ñlling the receptacles; `further, in. providing a filling receptacles with plastic'material, and is ex- v novel feeding plunger for feeding the plastic ma emplified as employed in ñlling. baking pans with terial;` further, in providing novel operating 1 meat dough, although it is obvious it may be em ployed in other relations.v " Y » kMeat dough of this character is a plastic mate ` means for the same; further, in providing novel means for placing the receptacles in proper re ‘rial containing finely ground or chopped meat and . lation with the feeding devices; and, further, in various ingredients, and is a thick, ñowable mass ` somewhat similar to sausage meat which is stuffed into sausage casings for making sausages. In the ing movements and the receptacle placingr devices. present instancey the meat dough is fed into a'pan ‘ for being baked to form'a meat loaf. 'Such meat dough has usually heretofore in the butchering art been placed in the pan by Athrow ing a batch of the same forcefully into the pan in an attempt to simultaneously eject the air from ` the pan >and from the mass of meat dough, it be-l ing found in such practice, however, that air pockets form between the meat dough and the 20 pan and in the meat dough, .and that portionsïof providing novel means to properly relate the feed The invention will be further readily understood , from the following description and claims, and from the drawings, in which nlatter: Fig. 1 is a side elevation of my improved device, shown in connection with an exemplifying sau sage stuii‘iing machine, instanced as employed in ~- an exemplifying feeding means for the recep tacles, partly broken away.

The receptacles into which it is desired to place 45 2.. '2,128,735 the plastic material are represented as baking the port 36 to direct the plastic material into the lpassage I5. The source of supply for the plastic material is exemplified as a usual stuffing machine 4I, in pans II in which to bake meat loaves. vPlastic material which is to be placed in the receptacles is represented as meat dough, exemplified at I2. The material is arranged to be fed into the recep tacle by means of a feeding plunger I3, which comprises a feeding channel I4, shown as a tube, provided with a feeding passage I5 and a feeding head I6, which is instanced as serving as a pres 10 sure piece, having a feeding passage Il, which which the supply of'rmeat dough is contained. The meat'dough is arranged to be forced through a suitable valve 42, connecting with the interior of the stuffing machine. 'I‘his forcing of the meat dough is Vobtained by Ymeans of a suitable piston 43, forced upwardly in the cylinder 44 by a suit registers with the feeding passage in the channel. „able pressure fiuid fed into the space 45 under or tube, and a feeding mouth I8 discharging into >the piston and supplied to said space through a the receptacle.

The rod extends into a cavity 85 in the bracket 23, a lnut 86 being threaded about said rod to adjust the plunger strikes the pan. I ` In order to provide a supply of fresh pans under the plunger upon successive descents of the " ‘plunger and to insure non-interference `between the plunger and said pans, »I provide a feeding means for the pans controlled by the position of the plunger' to avoid interference between move ments of the pans and the plunger. 10 The base 26 is provided with runways |2I at a helical spring 81 located between the bottom >Vits respective sides onk which _the pans are ar 88 of said cavity and a'washer 89 resisted by vsaid rangedto slide', an extension |22 of said runways nut, for urging» the rod upwardly and thereby> - raising the positioner 65. Downward movement of the rod is limited by engagement of the washer with the shoulder therebelow Ain the cavity (Fig 5). This upward movement is adjustably limited by a positioning nut 9|, a jam nut 92 clamping the positioning nut in adjusted position. rThe V20 positioning nut contacts the bottom 68 of the cavity 85, the rod passing through a'hole insaid bottom. A plug 93 vcloses the upper end of said cavity. Y The tube |4 is provided with a keeper 95,'shown 25. as an annular flange extending laterally vfrom `the tube and iixed to the tube.- A latch 96 coacts with said keeper to hold the plunger in retracted posi tion. The latch is pivotedÍ on a pin 91 extending therethroughand located in pivot lugs 98 on the bearing 2|. A knob 99 has Vthe shankrv|00 sur rounded by a spring |0| in a hole |02, in the heel |03 of said latch. The spring is located between the bottom of said hole and said knob and urges the knob outwardly for resiliently holding said 35 latch in engaging relation. The disengaging movement of said latch is limited by contact of the contact face |04 on said heelvwith the bear ing 40 2|. " ‘ > The latch is operated -by anv operating lever |05 having an operating'handle |06 anda bearing |01 on a pivot pin |08, the respective ends of which are located in bearings |09 inextensions ||0 of the links 12, constituting said links as levers for operation of the positioner. The operating lever f“ is provided with a finger | | | coacting with a iinger extending beyond the base being arranged to re ceive Ithe pans as they are being fed off of the 15 base. i - ' A carriage |23 is arranged to reciprocate in the base, resting on guideways |24 land being laterally guided by guideways |25 on the base. Actuating fingers |26 are on actuating levers |21, pivoted on 20 pivot pins |28 extending between the sides of the carriage. A> cover plate |29 covers the carriage and has openings |30 therein through whichthe fingers project. These levers are provided with resting faces |3| arranged to rest on the bottom 25 cross wall |32 vof the carriage, with the upper ends of the iingers below the plane of the bottoms of the pans, so that the fingers may be retracted past the pans. The levers are also provided with stop faces or heels |33 at the other sides of their pivots for contacting the bottom ofthe carriage when the fingers are in up-position topush the pans. ' Actuating bars |31 are at the respective ends of said levers and are pivoted to said respectivek 35 levers by pivot pins„|38. These actuating bars extend lengthwise of the carriage and are con nected by a cross head |39 at their operating ends. Movement of these bars> in receptacle feeding direction causes swinging movement of the pusherl 40 levers |21 on their pivots |28 during the first por tion of such movement of such bars for moving the pusher fingers upwardly into engagement with the respective pans, whereupon the heels of said pusher levers strike the bottom of the car 45 riage for arresting pivotal movements of said ||2 on the latch'lever for unlatching the latch. levers and thereby causing combined movements The keeper`- is provided with abevel face ||3 of the pusher levers and the carriage in'feeding andthe latch is provided with the coacting bevel _ direction upon further movement of the bars in l face ||4 for readily moving the keeper into en such direction, whereby to feed the pans to the 50 A50 gagingrelation with the latch when the plunger is raised. . v ` l To release the plunger, the operating handle |0'6 is depressed, thereby moving the *latchy in unlatching direction and depressing the lever |05.v YThe engaging relation between the iìngers |||,> ||2 is maintained'throughout movement of the operating lever, whereby desired depressing movement of the positioner 65 is also obtained, as these ñngers become fulcrums during the de 60 pressing movement of the operating handle for causing movement of the positioner toward the an. . p Theparts are so related that if the pan be not extent of the width of a pan, and the space |40 between neighboring pans, feeding a pan which has been under the plunger and has been filled, away from the plunger, and feeding the next empty pan centrally under the plunger.
