PERMANENT MOLD.

Application filed June 10, 1926. Serial No. 114,905.

My invention relates to a new and useful improvement in a permanent mold adapted for use in molding metal of various kinds to various shapes, but in the drawings I have shown the invention constructed to constitute a permanent mold for a vehicle wheel hub and the inventionis particularly adapted r or use for this purpose.

It is an object of the present invention to;

provide a permanent mold constructed and arranged so as to permit a maximum production with. the molding,'th1s maxlmum production resulting from quick pouring and rapid change of the material from the mold in that the materialmay be removed from the mold after chillingv so that it is not necessary to retain the metal in the mold during the entire time of cooling. I

Another object of the invention is the provision of castings which are of a higher grade, free from projectlons requlr ng chipping and a self-annealed casting, and one possessed of great tensile strength and a close grain.

Another object of the lnvent-ion is the provision of apermanent mold of this class which will be accurate when in use, the various parts being guided by means of a prominent fixture on which the mold is mounted.

Another object of the invention is the provision of a vehicle hub mold permitting a se-v cure' anchoring of the spokes in the hub.

' Another object of the invention is the economical pouring of castings in that the structure-and arrangement of the mold prevents'a wasting of material and eliminates the 'usualcleaning operation. Other objects will appear hereinafter.

The 1I1Vent1OI1COIlSlStSl1I1 the combination and arrangement of parts hereinafter de scribed and claimed.

The invention will be best understood from a reference to the accompanying drawings which form a partof and in which,

this specification Fig. 1 is a sectional View takenon substantially line 1-1 of Fig. 2.

. ring 7".

on subtaken on 1 sub vided,'the table 7 proper forming a rim supported by the spokes.v The table .is sup-. ported by standards or legs 8. Projecting upwardly from the. rim of the table 7 are supporting legs 9, each provided with a slot 10 in which engages the angularly turned end 11 of the spoke 12, which is to be affixed at its inner end in the'hub to be cast. Pro

srotrsrA, or RIVER ROUGE, MICHIGAN, AssieNoR To WHITEHEAD & KALES a jecting upwardly from the legs9 at opposite sidesof the spoke 12 are lugs 14 which serve to align the spoke 12 properly rela-. tively to the hub, which is to be castin the mold centrally located on the supporting table 7 Positioned on the rim'of the table 7 at intervals is a plate '17 having spaced:

lugs 18 between which engages the outer end of the spokes 16, the spokes 16 radiat' ing outwardly from the hub at one side, and

the spokes 12 radiating outwardly from the hub at the opposite sides, the spokes at opposite sides being alternated in a well known manner. The outer rim 7 of the table proper is connected by the spokes 7 to an inner Bolted or otherwise suitably secured to the'undersurface ofthe inner ring 71is a stripper :plate '18, this stripper plate being clearly shown in Fig. 4 and-comprislng a circular 'body having lugs- 19 therefrom through which bolts ori rivets may be projected into the'ring 7". Projecting downwardly from the stripper-plate 18' are guideflanges 20 and slidably positioned be-- tween the guide flanges 20 is a stool or sup-'- portingmember 21, said stool comprising a ring 21- projecting downwardly from which, at its periphery, and extending'slightly out-' wardly therefrom is a guide sleeve 21", this guide sleeve being adapted in its slidable movement for engaging theinner-surface of the guide flanges 20. Projecting across the stool 21 at opposite sideslof its axis are ribs 22' and 23 which are spaced apart, and'each ofiwhich is provided with an outwardly pro jecting lug 22- and 23 respectively.- Pro'.

jected through the-lugs 22 and23 is a shaft 24, connecting one end of an eccentric arm-"25 which is operated by the eccentric wheel 26- keyed to the shaft 27, said shaft 27 carrying a crank 28 whereby the samemay be rotated at will. i V v i As shown in Fig; 4 the stripper plate is provided with a slot 29 extendingat opposite sides of itsaxis'forbaflording a clear-1 V ance for the eccentric arm 25. Projecting upwardly from the ring 7 is a flange terminating in an inwardly projecting flange 31wvhich is adapted to engage a flange 32 formed on a center strip 33, this center strip being at its lower surface by the stool or supporting member 21. 'A cap 34 is provided for the central opening formed in the center strip 33. As clearly appears in Fig. 1 the spoke 16 is rested upon a flange 35 formed on the center strip 33.

Swingiably mounted on an upwardly projecting shaft 36, which is supported by the table 7, is a connecting arm 37, the opposite end of which is connected to one cheek 38 of the mold. A similar arm 39 is similarly swingably mounted on the table 7 and connected .to the cheek 40 of the mold.

The arms 3'? and 39 swing outwardly betweenv the upper spokes 12 and the lower spokes 16. Consequently it is necessary there be a clearance provided for the swinging of these arms outwardly into the position shown in Fig. 4 and for this purpose the. legs 9' which are shown in Fig. 2 are eliminated and other supporting means provided for the remaining spokes 122. As shown in Fig. 2 a ring 4:1 is secured at its ends to the legs 9 and directed over the top of the shaft 3.6 and 36. resting thereon. Projecting inwardly from the ring ll is a plate 42 carrying spaced lugs 43 and 44, between which theend of the spoke 12 engages. A similar plate 42, 42", and-42" is provided constructed as described for. the plate e2. Consequently it is thus provided that there is no projections upwardly from the table ring 7 in the path of the arms .37 and 39. r the. cheeks 38 and 40. A cope l3 is provided for. closing the upper end of the mold formed by the cheeks 38 and 40.. Projecting upwardly from the ring 41 are lugs 44; nd i5, between which is pivotally mounted a locking arm 46 for engaging the locking ug a? for locking the cope in position. Hand holds 4:8 and 49 are mounted on the arms 37' and respectively. 7

In operation the spokes are positioned as shown in Fig. 1, the upper spoke engaging either, the leg. or the ring 41 as described, at its outer end, and engaging at its. inner end the cheek L0. or 38.. The lower spoke is positioned as shown in Fig. 1 and already desc ibedposition by the stool 21 effected through a rotation of. the shaft 27. The cheeks. are then moved into proper position and closed, sand core 50- being formed in the base, of h ch ekslhe co e 51 is also ormed from seed tte the cheeks are, placed in, position. One of thecheeks 38 carries a link 52 swingably mounted; on a lug 53. An eccentric locking lever 54 being mounted on its free end! T is 1in t52 is adap ed to engage a hook lug 54 mounted on the other check so The strip 33 is then moved into neeaeaa that upon moving the eccentric 54 the cheeks may be locked against removal and retained in this position While pouring.

It will be noted that all of the parts are relatively to the strip and in seating the center strip in proper position.

While I have illustrated and described the preferred form of structure. I do not Wish to limit myself to the precise form of structure shown but desire to avail myself of such variations and modifications as may come within the scope of the appended claims.
