This invention relates to improvements in m'achines for manufacturing egg pulp, and in particular it relates to a machine of the suction-k operated type.

In machines for manufacturing egg 'pulp al The object of this invention therefore is to provide a machine which will have the necessary low contamination factor and will at the same time be rapid in action and simple in construction. f

To attain the objects I have found for instancel that the needle through which the content of the eggs is withdrawn should besuch that it will quickly and eiectively withdrawn the content of the egg, means should be embodied to prevent excessive introduction of shell fragments into the pulp, the pulp should be passed through conduits which are readily cleanable and should be isolated from the atmosphere to as great an extent as possible to prevent contamination by bacteria present in the air, and the arrangement of the machine should be such that over-filling of same with egg pulp is prevented.

The machine the subject of this invention thereforeembodies features which will attain thev Fig. 3 is a section of the shell trap and emulsiiler` but'with the several members partly disengaged from each other,

Fig. 4 is an enlarged View of the needle,

Fig. 5 is a side elevation of the head of the machine, l n

Fig. 6 is a fragmentary sectional view but showing the movable part of the head in its lowered position,

Fig. '7 is an enlarged sectional view on line 'I of Fig. 5, while Fig. 8 is a section as on line 8 of Fig. 7.

The needle I is supported to depend from a suction line 2 and has its lower end closed by a sloping floor' 3. Immediately above the lowermost edge of this downwardly slopingfloor 3 is an aperture 4 which communicates with the inside of the needle. The needle is held to the suction line 2 by a screwed nut 5 'which engages upon a depending threaded portion of the suction line and which bears against a shoulder 6 upon the needle. In this way the needle can be rapidly removed for cleaning or replacement. To ensure a goodr joint between the needle andthe suction line the shoulder 6 has a tapered top 9. To pre- 5 vent draining of the suction1ine2 throughthe needle when suction is cut off the needleis preferably made of` such length that its top projects slightly abovethe oor of the suctionV line as shown in Fig. 2 of the drawings; 10C?. The egg shell trap comprises a vessel II having within it a removable cylindrical screen I2 v which is coaxially disposed in such vessel and is located therein to leave an annular space between it and the vessel. The screen I2 terminates some -fdistanc'e above the floor of the Vessel and has Coaxially disposed within this screen I2 isa tube `-""terminates immediately above the lloor of the vessel II so that when suction is'applied to the tube it will draw the egg pulp out of the vessel.

The vessel II, screen I2 and tube I5 are all detachably supported upon a head' Il 'which has through it a central bore down which the .tube

I5 projects and is provided with an expanded portion 1ine'2 into communication with the inside of the screen I2. The head I 'I has a lower inter- T-nally threaded llange I9 into'which a flange 20 upon the top of the s-creen I2 is adaptedto be located, a threaded portion 2| upon thetop of the vessel II being arranged to engage the threaded'flange I9 and hold the ange 20 of the V-f'P-cie'eri I2 in place, the several contacting faces being of a sufficiently goot t to prevent `air'leakage. VThe tube I5 has near its top aseries of emuls'ifying apertures 22 which communicate with an expanded portion 23 of the bore of the head 495W, this expanded portion communicating with a continuation 24 of the suction line 2.

By means of the just described arrangement when suction is placed upon the line 24 such suc- I tion isvcommunicated to the inside of the tube TD5 through the emulsifying apertures 22 and thence through its lower end to thevessel' II. This suction causes a ilow intoand through the needle and along the suction line 2, through thel and being drawn through the tube I5 to the sucr ntion line extension 24. The tube I5 is held in m place by having upon its `top alvilange 25 which acrossit a floor I3 having a central aperture I4.y

tion I8 the purpose of which is to place th'e suceffected by m-eans of a tapered portion 34 on the stem 3|.

The suction line 2 and extension 24 are pro-` vided with

caps

35 and 35 respectively to facilitate cleaning.

The container 30 depends from an upper bracke f1 et 38 to which it is held by having a tubular ex-` tension 39 engaging in a socket 40 upon the bracket 38, the socket being provided lwith :a1

clamping screw 4l whereby the extension-may be locked in position. The socket 40 has withiniit' a chamber 42 which communicates with a flexible air lline143.

The lf'container-il fis held to the 'top.29 by means of ar central frodr45 which is secured to.

the bottom of th'e containerI 39 by a-ltapered-por,

tion 46 and a lock-nut 41, the rod having-its top projectingfthrough the socket 148 uponthe -brackx 1 et 38-v and engaged by ahand\wheel 48 whichhasv w a threaded portion engaging the -thre'adedlitop of the rod. A resilient1packng49 is interposedbetween the rim oi" thef container `3i) and fthe topf 29 to eiec't anairtight seal. Thecontaineris provided with 4"an outlet tap 50 of any. .usuallor approvedconstruction, .which tap .is preferably. locatedlsomedistance abovethe floor of the .con-r i tainer as shown.- so that the .lowerpartof ther container forms a sumpfor any .smallparticles of shell Which-might passthe. shell trap.

The 'Stop of the' containerfis preferably profV vided-witha closable air inlet 5l, thezpurposepf- ,f

which is =to permit :the vacuum in such.' container to be more effectively brokeniwhenremoving the:

egg pulp throughv the tap 59. r;

A guardl 52 carried .upon the rod `i5 prevents splashingof the pulp .from the containeriagainst the top 29.

The bracket38 is supported uporr-a: vertical column-.53 toi be movableiaxiallyl thereon; rows of ballv bearings H5.4 disposed lbetween"Y a. supporting stemztr upon.. the top of the column=53 and a, cylindricalbearing member55 upon the bracket 38 facilitating. such movement and ensuring a support.. having ,very low rictional resistance.

The ball bearings 54 are held in cages 51 and engagein vertical grooves in the. cylindrical bear.

normally serves to; project the bracket-upwardly,"- suchupwardvmovement:beingflimite-dwby a stop nutGS upon the stem. 59, the purpose; of the'. springid being'to serve as a weighingdevice to prevent the filling of more than 1the predeter mined; amount of pulp 4'into ythe' containerSU.

The'spring isI enclosedV in a cover 61. Theten sion of the springfell maybe madeadjustable by interposing -a collarebetweenit and the rest Y95 and "supportingthe collaraon setscrews passing through the rest.

Supported by thevstem'ill of the column -53 iss 1 line 1| in which is a control valve 12. The valve comprises a gate 13 operated from a shaft 14 by a iinger 15, the shaft 14 having upon it a lever 15 upon which is a cam 11 having a notch 18.A

The means which control the valve 12 comprise a vertical rod supported in bearings 8l upon the cylindrical bearing member 55, the rod being provided with an adjustable stop 82 and aiv spring 83 arrange-d to normally project the rodupwards. lWhen the container 30 is empty or contains egg pulp below the amount `at which it is set to operate the valve is held open by the end of the-md80 engaging the notch 18 as shown more particularly in Fig. 5. When however the weight of pulp within the container reaches a predetermined amount .the downward movement of the. bracket 38 causes the stop 82 to contact with the y upper bearing 8l under influence of the spring 83 whereupon continued downward movementi ofthe .bracket `38 withdraws: the endof the rod 89 from the; notch.18 and-:permits .thetlever 16 to fallto the .positionf'shown in Fig. .6, this` action shutting off the suction line from'the. cony erating arm ccupledby means of a'linkI 88 to a stud 89 uponqthebracket'f38pthe link'fhaving a slot 90 to permit some 'amount of downward movementof the bracket138 before' the. counter f is operated,4 .t The column-53 is secured to a base92 which base alsosupports `a:platforn'n93 upon whichra tin maybe placed .-when'llingfsame from the.: container. 30. The platformis secured 1uponna..

A guide91 is held to` therplate' formv 93 by means of boltsa98 andfservesv the` purpose of ensuring alignment of thectin `relatively to the tap 58, the guide91- and. vthefplat-V form 93 being provided respectively with i slots 99 and |00 to enablethedposition .of such guide' to be adjusted.

In operation the veggs .whichf are .to be evacuated areY struckupwardlyon to the needle .|so r `that the needle is inserted therein. .As suction isV applied: to thecontainerll,.which ,suction is communicated. throughtheseveral lines Yto the f needle the content of thewegg is drawnfout of shell and passes ythrough the. hollow` of the .nee-

kdle into the inside of the -screenilZ and. thence throughsameinto the vessel `AllV and.out through.

the tube I5 into the container. .flThepulp is here removed. from theai-rv anddepositsin the container.;` .As the 1weight ..of the Vpulp ,v in the container increases the bracket 38 movesdownV upon the supporting stem. 55, the initial movee ment causing .the rod -80 to remain'in engage?. ment with a notch 18, the spring 83 expanding.

fromthe container :3U andarlo further .pulpingV can take'place until the container 36 hasbeen emptied, which .is effectedby positioning a tin or otherstorage receptacleupon.theiplatform .93 and opening: thetap 50.1As the .weightfwitmm pulping it is then only necessary to reset the lever I6 to apply the suction to the container 30.

AIf the pulp does not flo-w out of thecontainer 30 freely enough the air inlet tap 5I is opened to permit a greater iiow of air` into the container to break the partial vacuum therein.

The machine can be readily cleaned after operation by drawing a cleansing iiuid through same or by dismantling which as will be seenfrom the drawings can be easily carried out, the needle I being removable from the suction line 2 and the screen I2, vessel Il and tube I5 being all removable from the head I1, the entire needle and egg shell trap section being removable from the container 30 by disengaging the nut 32. The container itself is removable by unscrewing the hand wheel 48 to release the rod 45 whereupon the container will be free for removal.
