(01. 107-8) This invention relates to an improved pattyat its lower side with preferably circular sockets forming machine of the character shown in my 13 in which are fixed pads 14 of rubber or the co-pending application for a similar invention like so that when the base is placed on a table, filed January 21, 1933, SerialNumber 652,916. as conventionally illustrated at 15, the pads will Generally stated, the invention seeks to refine prevent marring or scratching of the table.

Fitting snugly in the collar'is'upj- 12. Adjacent these cars, the-base is provided standing cylindrical hopper 33 which' may be formed of suitablesheet metal and, as will be observed, the lower margin of the hopper is spun outwardly to provide a flange 34 engaging in the cavity 32 for rigidly and securely connecting the hopper with the top plate. At its upper end, the hopper 33 is flared to provide an overhanging annular flange 35, and formed insaid flange, as particularly seen in Fig. 5, are circumferentially spaced notches 36.

Detachably mounted upon the upper end of the hopper is an'anchoring' head including a sectional sleeve 3'7 from the ends of the sections of which project mating flanges 38. near the upper ends of the flanges '38 are bolts 39 pivotally connecting the sections of the sleeve with each other, these bolts being reversely pree sent'ed and each extending freely through one flange of each sleeve and being threaded into the confrontingflange of the other sleeve so that" each of the sections carries one of the'boltsi' at the limit of their movement toward each other.

In thus mounting the springs, the tension thereof is equally distributed between the sleeve sec-' tions. Projecting from each of the sections of the sleeve 37 is a pair of diverging legs 43 which are provided at their lower ends with depending hooks 44 adapted to freely p s through the notches 36 of the flange 35 of the hopper 33 so that after the head has been lowered to dispose the hooks through said notches, the head may berotated to the position shown in Fig. 5 for engaging the hooks beneath the flange 35. As will beperceived, this construction also admits of ready detaching of the head. As shown in Fig. 6, each of the sections of the sleeve 3'7 is in-. ternally grooved near its lower end to removably receive asemicircular shoe 45 and formed on the shoes, as seen in Fig. '7, are pawls .46 having beveled upper faces. 1 e

. gSlidable through the sleeve 3'7of the anchoring head is a barrel 47 provided at opposite sides thereof with longitudinally spaced pairs of openings 48 and fixedto the upper end of the barrel is a cap 49 fromwhich extends alined lateral handles 50. As seen in Fig. 2, the cap ;49.,is internally recessed and the upper end of .;the barrel 47 is spun outwardlyinto said'recessyfor rigidly and securely connecting the cap to the barrel. Slidable through the cap 49 isv a follower stem 51 provided at its upper end with .a knob 52for limiting the barrel 4'7 against upward dis: placement from the stem and screwed upon the lower end of, the stemis aconcavo convex follower 53 snugly but slidablyfitting within the hopper 33. Surrounding the stem 51 to restat one end againstthe follower and at its opposite end against the; cap 49 of the barrel 47;is a spring 54. p Inuse, the anchoringv headis turned on the hopper 33 until the hooks 440i the legs 43 register with thenotches 36 in the flange 35 of the hopper, when the: headis lifted upwardly for displacing the. follower assembly as a unit from the hopper. vThe hopper is then, as suggested in Fig.2,filled with meat, when the follower assembly is replaced; The handles 50 are then grasped and the barrel47p 1Sh QdQWIk,

Arranged wardly through the sleeve 37 of the anchoring head. As shown in Fig.- 6, the pawls 46 are engageable in the pairs of openings '48 but as the barrel is thus pushed downwardly, the wall of the barrel will coact with the beveled faces of said pawls for rocking the lower ends of the sections of the sleeve 3'7 apart so that downward pawls will be caused by the springs 42 to snap into said pair of openings so that upon release of the handles 50, the pawls will securely lock:

the barrel against upward movement. Thus, the spring 54 will be held under tension for forcing .the follower =53downwardly and feeding the meat within the hopper33 downwardly against the forming knife 21. Y

In-this connection, attention is directed to the fact that when-the supply of meat in the hopper 33 becomes exhausted or nearlyso, the follower 53 will move in o engagement with-the shoulder 31 which will then 'seirveto limit thefollower against further downward movement so that the follower willbe held away from theforming knife 21 and by thengrasping the handles 50 and pushing downwardly on the barrel 47 to free the pawls 46, the. barrel may then be rotateduntilthe openings 48 are out of line with the pawls when; of course,: the barrel may be shifted upwardly and the follower assembly removed from the hopper for reloading rthe hopper.-

To operate the machine, the handle 24 is grasped and swung to the right, for instance, as seeninFig. 3, to dispose one of theope'nings 22 in said knife beneath the discharge opening. 29 of the top plate when .the meat in the hopper 33 will be feddownwardly by the follower 53 into said opening of the, knife. The ,knife is i then swung to the left when the other opening22 of.

the knife will be disposed beneaththe hopper to be filled with meatwhile the previously; filled opening ofthe; knife be brought into an exposed position atthefront ofthemachine so thatthe meat patty therein may, be readily'dis- Thus, each time the forming V the screws 2'7 and displacing the top plate.

the-formingknife 2lmay beremoved and another formingknife of eithergreater or less thickness substituted in lieu thereof or the-substituted forming knife maybe of the samethick ness as the forming knife 21 but may have patty forming openings of either greater or less diam'e ter. The size and thickness of the meat patties delivered bythemachinefmay thus bexreadily controlled by the choice of. the putty forming slight modification wherein the, sections 55 of the sleeve of the anchoring head areprovided with, integral .paw1 s 56 like the pawls '46, the

shoes 45, as in the prior embodiment of the invention, being eliminated. In some instances, this modified construction may be found adaptable. Otherwise, however, this variation of the invention is identical with the preferred embodiment thereof and further description is accordingly believed unnecessary.

Having thus described the invention, I claim:

1. In a device of the character described, a hopper, a follower movable therein, a spring for advancing the follower, a barrel accommodating said spring, the barrel being adjustably shiftable for tensioning the spring, and an articulated anchoring head carried by the hopper and movable for locking the barrel in adjusted position.

2. In a device of the character described, a hopper, a follower slidable therein and provided with a stem, a barrel accommodating said stem, a spring disposed within the barrel to act on the follower for advancing the follower, the barrel being adjustably shiftable for tensioning said spring, and an anchoring head carried by the hopper and formed of pivotally connected springactuated sections having pawls engageable with the barrel for locking the barrel in adjusted position.

3. In a device of the character described, a hopper, a follower slidable therein, a spring for advancing the follower, a barrel accommodating said spring and adjustably shiftable for tensioning said spring, a sleeve formed of pivotally connected sections having legs engaging the hopper, the sleeve slidably receiving the barrel therethrough, and pawls carried by said sleeve sections and engageable with the barrel for locking the barrel in adjusted position.

6. In a device of the character described, a hopper, and a follower assembly carried by the hopper and freely detachable as a unit therefrom, said assembly including a follower movable within the hopper, a head to coact with the hopper for supporting the follower, and a spring for advancing the follower and normally holding the head engaged with the hopper.
