RECEPTACLE-HANDLING MEANS FOR UNIT-MEASURING yMACHINES.

Original application filed July 1, 1925, Serial No. 40,796.

Our invention is an improvementl in machines for measuring units of mobile material, as ice cream, for separating such measured units from a mass, depositing themv separately into containers, capping the containers, and ejecting the lilled containers. The invention also embodies an improved mechanism for placing the containers in a carrier whereby they are brought separately into position for lilling, capping and ejection.

The present invention is generally similar in its main elements to that shown in a prior rapplication liled by C. N. Bergmann et al.

on April 4, 1925, Serial No. 20,696, but differs therefrom mainly in the substitution of an intermittently rotatable carrying turret for the receptacles, in place of the longitudinally movable carrying trays thereoit, as well as in other respects hereinafter described.

This applicationis a division of our prior application tiled July l, 1925, Serial No..

40,796 for unit `measuring machines, and refers particularly to the means tor moving the receptacle or cup in, through, and from the machine.

In the present construction we provide a rotatable turret wheel having an annular series of cup receiving cavities by which each cavity is brought successively in registering position underneath the cup depositor, the filling mechanism and the capper, and then over the ejector. v v

The present inventionrefers particularly to the lreceptacle handling means, including the turret wheel carrier, its manner ol' construction and operation, the ejector,bag iller, the means for actuating the several operative mechanisms in sequence with suitable rest periods, and various features of detail construction, as shall be hereinafter more fully described.

In the drawings illustrating one preferred embodiment of the invention:

Figure l is a view of the machine in front elevation; f

Figure 2 is a partial central vertical section Von the line II-II oit' Fig. l;

Fi -ure 3 is a horizontal sectional View on the line Hl of Fig. 2, with the turret renamed and partly, broken away Divided and this application filed May 27,

Serial No. 111,994.

Figure 4 is a plan view of the turret;

Figurev` 5 is a detail view showing the ejector plunger and its actuating mechamsm,

Figure 6y is a sectional detail view showing the cup ejecting and supporting mecha'- nism with. the cup in the turret socket;

Figure 7 is a similar view showing the cup elevated bythe plunger.

Referring to the drawings, the operative portions of the machine are mounted upon and within a hollow boX shaped base 2 of cast metal supported upon the floor or foundation by a suitable flat pedestal, as in Fig. l;

it the liront middle portion of the base is a vertically arranged bearing 3 in which is rotatably mounted the central depending stem 4 of the turret 5. Bearing 3 is -cast integral with a laterally extending transverse bottom wall 6, forming a concave dish Yor basin, surrounding the turret .beyond the lower base and providinga rearwardly inclined collecting and drainage cavity for excess cream, washing, etc. y

As shown in Fig. 3 the outer edges 7 are rounded, and surround the turret, a drain connection being made at the lowerlevel for cleaning purposes. Turret 5 is generally of the form oit a flat wheel or disk having an annular series of tapered socketsS open` at the bottom and provided with lateral clearance openings 9 for the discharging plunger l0. Sockets 8 are of a size to vreceive, and support on their flanged bottoms the cups or receptacles L as they are deposited therein ior tilling.- Y

It will -be understood that sockets 8 aie in multiples ot' four, as twelve,rso as to always loca-te a socket at four equidistantl points around the center in position for cup depositing, filling, capping, and discharge at each intermittent rest period of the turret. f

The several mechanisms for such purpose receive their operative movement from a main transverse shaft 11 mounted in bearings 12-12 of the main trame 2. Shaft 11 is driven through gearing 13-14-15-16 orsi-her suitable gearing, from amotoi? 17A Said motor is mounted on an it erior' .'iupL parting' shelf or base Y18 loli and is provided with the necessary current supply, controls, `rete. i

. Turret '55 is intermittently rotated, say one twelfth ot' a revolution with an interivening rest period, 'by a 'ratchet wheel Y19 and :pa-Wl `29 'of lever iarm 2'1 `by Cain 22 :extendin'g rtremor 4movable with gear 13. Lever 21 is pivoted at 23 and its terminal roller 24 is held .against the annular .tace of cam .2.2 by a spring 25.V 'Pawl 20 is pivoted at 26 ito the other .end fot llever 2l and lits tree end has a terminal pin or roller 2T adapted toengage the successive teeth sockets 28 ot the ratchet Awheel 19 tor each, operation, under con-trol of spring L29 vsecured to the other end et the pawl and to the leven-as shown.

The under side of ratchet wheel 19 is provided with Va series ot' holding sockets 30 adapted `to co-act vwith roller "31 of -a spring retracted stud 32 mounted in a supporting housing '33 of the discharge plunger housing 34. In its intermittent rotation, one loomvplete revolution oit `the turret will `bring each of the annular cavities 8 into rest positions A, ByC -andl iD, respectively. In' such positions, `a cup is placed in the cavity at A, the vcup is il'led at B, the cover or cap is placed in the cup at C, and the filled cup is discharged upwardly at il).

" 'charge opening in the casing. 1A `reciprocable placing within lthe, Vupper edge bleach cup a` AThe `cups a provided with a rib b are nested in rarverltical column above position Ain a slotted magazin-e tube 35 rigidly snppotred from ithe rear gear housing extension. Each cup tisitapered t lit snugly within the tapered cav-ity'8 of turret 5 without binding. Means `are provided `below tube for lowering the enthnost cup` into the cavity and arresting ,and detaching =it while the remaining cups are lifted upwardly and there held until ythe turret vhas `moved one space, when such operation is repeatedfas fully described :in the parent application Serial No. 40;796.

Vhen the cup is moved `around to position B `vit `there `illed with ice cream, or other commodity, lby .means similar :to `that shown in the parent application noted; Depending below a hopper bottom 59 of hopper E is a 'shortcyli-ndrical casing 60, supported ifron'i the Aupper frame of the machine.

Within casing is a rotatableydrum or barrel having a middle transverse passageway adapted to register with 'the bottoni opening ofthe hopper and anopposite dis- 'vplunger acts to withdrawn and eject aineasured Aunit of ice cream into the 'cupat each half revolution of the barrel yat location B.

'The 'filled'eup's are capped 'at position C by thin paperdisk 83 having 'a projecting withdrawal tang. 'Said disks are mounted in a vertically arranged "bank in a magazine tube 84, 'slotted along fits v'outer side, and tixedly bolte'dfto theplunger rframe, provided with"` the cap placingplungen When the lilled and cappedcup arrives at ,position iD it is rejected upwardly `@into a receiving tube 4140 by plunger 10.

Said plunger has a series of laterally dirverging wings 169 adapted vto pass through =end of ylever 142 pivoted to a cross shaft 143.

A cani lever 144 is also pivoted on shaft 143 and extendsupwardly by la terminal lhaving a roller 145 engaging the cam groove 1461er cani 147 on -shai't 11. As the cam rotates, the groove so designed as to throwthe vplunger-1() upwardly at the proper tiene to disdharpge `the Vfilled and `capped cup iupwardly towards the tube 140.

-rtljinari`ly, levers 142`and144 will operate together as lone piece, but are made separate to allow for easement ofithelii'ting pressure on the cup in case of jamming.

For "such .purpose -lever "(142 bears up lagainst lever 144 by anextended lug 168 due yto the holding action of spring 145 connecting the levers across the angle joint, as in Fig'. 2, Normally `tliie'icam 1will impart lil-ting and *lowering movement l"to the plunger, '7

ibut it the plunger is arrested for any reason,

-as by interference with the turret, .the hinge joint willopen, allowing thefcain movement of section 144 to continue without actuating "the plunger, `un-til the obstruction or interl'ference is remove-d or adjusted.` c p'` The'shape of the plunger 10 tends to'avoid V'annninef or interference. The lateralwinvs 1 b D `169 are provided withfterminal abutments and inwardly sloping upper shouldered faces 171 which act -to centi-alize thefcup and plunger, Vand to fsupp'ort the `cup ttor liiiting by its lower 'annular edge against Jtheshoul` 4dered `abutlnents 170,1thus `relieving pressure against the :flat thin bottom-of the cup.

Between the bottom of `tube 149 `:and the ,y

surface of the turret 5 arelinterposed a pair ott automatic inwardly gravitating cup ar resting jaws 246-246; 'Dheseas shown are pivoted at"247 and -fall inwardly by gravity x against stop abutments 148, and have inner inclined 1faces'terrninating in narrow con- 'cav'edlips l Y i As the cup is lifted by the plunger, it passes between and above such Llips which then fall inwardly by gravity `and engage Y `the irim b as "in Figi?. Atfthe Sametime.

that each succeeding cup is raisedfit kpushes the already glifted `and'*supported cu-ps upwardly a distance equalling the depth 'off one -c-up. The entireseries arie thus supported by the jaws 146,each 1 cup supporting the next 'of -the Iadjacent cup resting thereon within the Wider upper rimb.

uppermost one byjitscover, the betteln edge Tube 140 is slotted along opposite sides as at 152 for inserting the fingers in removing any selected number of cups, and is prefer-l ably inclined at the top as at 149. yThe base of the tube is flared as at 249 foreasy entrance, and is secured in an upperextension 150 of housing 34 as in Fig. 2. Hinge pins 247- are also secured in said support together with the cross bars 151 having the confining abutments 148.

In assembling the filled cups for refrigeration, storage, shipment, etc., a paper bag e is placed over the tube 140 in inverted position, the tapered top 149 facilitating such placement. As many cups as are desired, say four or` eight, are gathered upwardly into the bag by lifting the cups, with the surrounding bag, by inserting the fingers through the opposite open and closed end slots 152.

Thus the cups and the enclosing bag are removed together as they accumulate by .finally lifting throughl the open slot at one side, the bags being closed at thelower open f' end in any suitable way.`

It will be understood that each of the socketsS of the turret is occupied successively by a cup "at position A, and that as each arrives at the subsequent positions B, C, and D, the operations above described are performed. l

Therefore as each socket arrives at the final discharging position, a filled cup is ejected, the. empty socket then. passing around to position A where a fresh empty cup isdeposited.

The operation is continuous, rapid, and substantially automatic7 merely requiringrenewal of the cup and cap supply in their respective magazine tubes, removal of the filled cups. intok theirpaper bags, and of course maintaining a sufficient amount-of ice cream at all times in the hopper.

The several movements are all effected through the various cams and their transmitting levers in the manner described andl illustrated.

The timing of the operations is easily controlled by the design and setting of the cams and the various adjusting, limiting and controlling devices and mechanisms. Themachine as a whole is verycompact and of comparatively small size, considering its .capacityV and speed of operation.

It may be changed or varied by the skilled mechanic in various details or features, or

otherwise modified within the scope of the general principle of operation, but all such changes are to be understood as within the scope of the following claims.
