Application mea my 17`,"19s. seriai No. 278,441;

My invention relates to ice making machinto the upper ywall 7 and inset slightly y from-the endy walls 1, define the open chamber ery and more particularly to ice can fillers.`

In the manufacture ofL ice it is common practiceto fill the cans in which the icefis frozen from measuring containers having capacities substantially equal to those of the from a double measuring container; variations in volumes in the filling containers or.

losses in transfer of water to the freezing cans resulting in corresponding variations in size collar 15. Pairs of opposltely directed arms yand weight of the frozen ice blocks.

It is the rincipal object of my invention to insure uni ormity in the ice blocks, and for accomplishing this object I provide an im- Y proved form of measuring container and conforcing walls such as 6, an-d an upper wall 7,.

trol means for measuring proper volumes in the measuring containers for delivery to the freezing cans. Y f

It is a further object ofthe invention to provide for adjustment of the measuring containers for difl'erentwater pressures.

In accomplishing these an-d other objects of my invention I have provided improved de` tails of structure, the preferred forms of which are illustratedin the accompany draw` Y ings, wherein: Y A

Fig. 1 is a detail perspective view ofan ice can filler embodying my invention.

Fig. 2 is a vertical sectional view on the line 2 2, Fig. 3. Y

Fig. 3 is a vertical sectional view on theline` 3-3, Fig. 2.

Fig. L1 is a operating mechanism.

Fig. 5 is a view partly in section of a flexible joint for a valve operating mechanism.

Referring more in detail to the drawings:

1 designates a double measuring container? having a bottom wall 2, side walls 3, end wallsy 4a solid partition wall 5, perforated rein# the various walls enclosing the separate chambers 8 and 9. The volume of each chamber is equal to a predetermined volume desired in an ice 'can such as used for containing the water to be frozen into blocks vof ice' of stand- A ard shape and weight.

i A continuation of the side walls 3 above detail perspectivel view of avalve the4 upper wall 7 and end walls 10 fixedV 11 for containing surplus water and the valveV 'control mechanism presently described, the' strained fromv lateral movement by a thrust 16 and 17 having bifurcated ends 18 arefixed` on the shaft in spaced relation, and a like arm 19 is mounted on theshaft outside the wall 3.

Located within the upper wall 7 and Valigning with the ends'of the paired arms 16 and spherical valves 22 attached by flexible links 23 to the arms 16. The links 23 linclude flattened portions 24 received between the y'loifurcated ends 18 ofv the arms 16 and` pivotally connected thereto bybolts 25. Enlarged cylindrical portions 26k provided with slots 27 and vannular reinforcing flanges 28 telescopingly receive the ends of valve stems 29, pinsl 3.0 extending transversely through these ends and engageable with'the slots 27, connecting the linkage members. It is obvious that with such a connection a flexible linkage member is obtained, a considerableL 17 are ports 2O and openings 21, the ports 20. f

being providedY with seats 20 for semi- `70 degreel of rotarymovement of the arm being..

possible' without moving the valve. Guides 31, fastened to, and extending inwardly from the side walls 3, are provided to insure proper alignment of the valves 22 with their respective seats y i Surrounding the openings 21 and fixed to the upper wall 7 are conical'guards' 32, terminating in cylindrical portion-s' 33, the Vupper edges of these portions being above the water level of this chamber to prevent the passagel of water from the open chamber 11 into the lower chambers 8 and 9 through the openings 21. Linkage members 34 passing through the openings 21 are, except as to length, indentical in structurewith the linksY 23, and operatively connect the arms 17 withy outlet valves 35, cooperatively engageable with the seats 3G of outlet fittings 37 4secured in the bottom wall 2 for each of the chambers 8 and 9; the outlets being in vertical alignment with the openings 21.

Guides 38 iixed to the side walls 3 retain the outlet valves in properlposition relative to the'irlseats. "Plug screws'39 screw-threadedlyy iitted in openings 40 inthe end" wall 4, provide access to the outlet means.

Pivotally received between-the biiurcated ends of the arm 19 is a bar 41, having stop iianges 42 fixed near its lower enda-ndcooperable with complementary iianges 43 fixed to the outer faceo'asidewall 3. f-'It will be noted from- Fig. 1- that an upward movement of this 'banwill lowerthearms'l and raise vthe arms 117, thereby?removingthe outlet valves from' t1i eirseats,'the control valves 22 @remaining fclosed. `Downward movement ofthe barwill reversefthe operai tions of the valves.l

The lower opening'of'the Vhousing is iprovided Vwith an outwardly ex- ;tendingange 48, to which is attached, as by bolts 49, a disk 50 preferably vof Vsoft rubber andv mounted between Vwashers 451. l edge or a circular opening 52 in the'di'sk coin- ;pri-sesgaseat for a Yspherical inlet valve`53 fcontainjed within-the,housing'44- The Fixed to Vthe upper extremity ofthe' valve isL a-guide rod S4-'adaptedy for'jreciprocal movementinan opening 55 ,of aguide p'glate 45 156 secured lto a plug 'screw v57 Afitting Ein'the `'upper-openingof the "T litting 44. Secured centrally to the lower extremity of thesphere is alvalve stem, Yhaving'a bifurcated lower ,lend 58 for receiving therebetween one end of an operating lever 59 pivotal on a cross pin 60 extending through the lower en dfof 'Y the valve stem. Paired bracketsi61 Asecured by the bolts 49Yto the housing flange 48 are provided with downwardly ei tendin`gf ears 4suiiicientlyspaced to receivefthe operating lever 59, hinge'dly mounted I"therebetween on va pin 62 servinga ulcrum or'the lever.

The opposite en d of the lever '59 is lfitted between brackets' 63 iixed to the annular wall 464 of afloat 65.

A bracket 7 O having lateral iianges 71 is fixed to the upper wall 7 for guiding the operating lever 59.

In ordinary practice a can tiller of this kind is mounted on suitable supports in an velevated position in the refrigeration plant, vfthe Finletgpipe being 'connected to' source oi ""water`sup'ply under pressure.
