PATENT OFFICE MONROE S. CLAWSON, OF MONTCLAIR, NEW JERSEY; ANNA IRONS CLAWSON EXECUTRIX OF SAID MONROE S. CLAWSON, DECEASED MULTIPLE PERMANENT MOLD Application filed August 30, 1929. Serial No. 389,516.
The invention relatesto metal founding and has for its general object the provision of a novel multiple mold of the chill type adapted to be power operated into either I I open or closed position.
An important ob]ect of the invention is toprovide a multiple chill mold in which the mold sectionsin the successive units may be opened or closed by fluid pressure means.
A more specificobject of the invention is to provide a multiple mold structure having a lazy tongs and supporting and operating means whereby the sections of all the units maybe opened or closed simultaneously.
Another objectof the invention is to provide an apparatus of this character embodying a novel connection or mounting of the mold units with or upon the lazy tongs, the units being moreover adapted to be con nected'in a peculiar manner for simultaneous operation and being additionally equipped with means for engagement by hoisting mechanism so that the units may be lifted about wherever their use is desired or when they are to be stored away.
Another important object of the invention is to provide a multiple'mold wherein pouring into all the units may be done at one'oporation, thereby saving time as well aslabor.
Still another object is to provide a mold unit of novel form andequipped with a removable baffle plate whichoperates to prevent delay in refilling the mold as it will be dislodged with the casting in the event of sticking and may be replaced by another promptly. I
The invention further contemplates the provision of various. improvements in devices of this general class.
An additional object is to provide a mold structure and assembly whichwill be simple and inexpensive to make, assemble or install, positive and rapid in action, efficient and durable in service, and a general improvement in the art.
To the attainment of the foregoing and other objects and advantages, the invention preferably consists in the details of construction and the arrangement and combination of parts to be hereinafter more fully described and claimed, and illustrated in the accom-. panying drawings in which:
Figure 1 is a plan view of the apparatus showing the mold units in closed position ready for pouring,
Figure 2 is a similar view with the mold units in opened position,
Figure 3 is a side elevation, 1
Figure 4 is a fragmentary plan view on a larger scale showing the mold units more clearly,
Figure 5 is a cross section through the assembly and showing a side elevation of one of the mold section, and
Figure 6 is an edge elevation of a mold unit on a larger scale, with parts broken away and in section.
Referring more particularly to the drawing's, the numeral 10 designates a supporting truck of any ordinary or preferred detailed construction and mounted upon wheels 11. This truck is provided in its top with an open portion 12 at one side of which is a guide '13. Located within the recess 12'is a group of mold units 15 supported upon a lazy tongs 16 and adapted to move along the truck and guide 13 under circumstances to be described.
This lazy tongs structure is represented as comprising a plurality of similar links 17 pivoted in crossed relation by socketed members 18. v At one side of the tongs the links are pivotally connected at 19 while at the other side they are pivotally connected by members 20 having sockets 21 therein. The mold units 15 are of the chill type and are of general rectangular shape and are of course arranged in mating or complementary pairs as clearly indicated. Secured upon the rear edges of the units of each pair are angular bracket members 22 formed with interfitting hinge knuckles 23 through which passes a pivot pin 24:. These pins are received with in the socketed members or rollers 18 at the points of crossing of the links 17. The members 18 slide along the groove 13 and assist in guiding the .tongs. The sockets inthe members 18 are indicated at 26. By this construction it will be seen that the units of each pair may swing toward or from each other. as the case may be in the operation to be explained. The lower forward and outer corner of one unit in each pair is shown as formed with a boss 27 formed or otherwise rovided with a trunnion 28, these trunnions i geceived within the sockets 21 in the mem which connect the ends of the links at one side of the lazy tongs structure. As the other mold unit of each pair has no direct'connection with the links 17 and as it is necessary that all of the units move simultaneously toward or away from each other I may provide angular brackets 29 on the forward edges of the units, these brackets being agilertured for the reception of inverted U- s ped hooks 'or staples 30 which will constitute an operative connection between the unitsmfleach pair with the adjacent ones of thenel't pair. As it is intended that any desired number of units can be used, of, course w ithim-eertain limits, and as it may at times be necemary to add or remove one or more, the units are preferably provided with angulaniapei'tured brackets 31 at the top, these adapted to be engaged by a crane or other hoisting means.
of the cavity in the mold units is chem immaterial and is therefore not shown. However, the confronting faces of each pair of unitsmust be flat and true so as tmfitclosely and prevent escape of molten metal during ouring. A very important feature. the invention is the fact that all of the molds may be filled at the same time. Ilr'carryingout this feature I form all of the mold units with atrough or gutter 32 which willexbendthroughout the entire series, the gutteu-ofeourse communicating with mating spmefopenings, 33 in the confronting faces (vs-she. units so that molten metal poured into the trough and running therealong will flow-into all of the molds. The gutter forming recesses in the mold sections slope toward the sprue openings, so that the gutter is not'of uniform depth but is rather in the form of a connected series of pockets. The of this is that as the metal flows into the mold cavities the surplus will collect in the individual pockets, so that it will not solidifyas a continuous body and prevent opening of the molds.
. Another important feature of the invention is the provision of a removable baflle for each pair of units, this baflle being detachably connected therewith so as to be capable ot'pulling out in case it sticks to the cast metal whenthe same solidifies and when the mold is opened. This baflle is represented as comprising a rectangular plate 34 slidably rece ved within alined grooves 35 in the mold units. when the units are all in assembled relation as shown in Figures 1 and 3 the ends oi these bafle plates will be in abutting relation and will form. in efl'ect, a continuous wall at one side of the trough or gutter 32 which will operate to prevent splashing or overflowing of the molten metal during pourhave their ends pivotally connected at 43 with ears 44 on the outermost mold units. Clearly, there must be a slot and pin provided, or its equivalent, to permit the necessary play. The cylinder is equipped centra ly with a fluid pressure conducting pipe 45 and at its ends with similar pipes'46.
In the use of the device, it is of course assumed that the laz tongs. structureis constructed and assem led as shown. Any desired number of mold units may then be placed in position upon the lazy tongs with the pintle pins 24 engaging within the sockets 26, and with the trunnions 28 on the alternate units engaged within the sockets 21 in the members 20. The U-shaped members 30 are then laced in position and the arms/l2 connect with the cars 44. Assuming that the molds are all in open position as shown in Figure 2, it is apparent that the istons 37 are at their outermost positions'wlth the lazy tongs extended. When it is desired to 'cast, fluid pressure is admittedby suitable valve means, not shown,-through the pipes 46 and will operate to force the pistons 37 toward each other, the air between them'exhausting through the pipe 45. As the pistons are thus moved, the arms 42 will move toward each other and will close up the tongs with the result that all of the mold units 18 will be forced into contactin relation. To facilitate coolin after casting, the, outer faces of the mo (1 units are represented as corrugated or ridged except at the areas where they must contact closely to form a continuous gutter or trough. After the mold units have been forced together, the baflle plates 34 are slipped into the grooves 35, subsequently to which the molten metal is poured into the trough or gutter'so as to enter and fill the cavities in the molds. After the metal has set and it is desired to remove the castings, the operation is reversed, that is to say fluid pressure is admitted through the pipe 45 to forcethe pistons 37 and arms 42 outwardly so as to open up or extend the lazy tongs and swing all of the mold units into the open position shown in Figure 2. The castings may then of course drop down through the open part of the truck. Before the castings can be removed it is of course apparent that the baflle plates must be removed from the slots or grooves in which they are received.
It will be noted that the present device distinguishes clearly from the turret type of mold or mold holder in that the molds are carriedby a truck movable along a trackway step by step beneath the pouring spout 47 instead of having the spout movable along over and above a series of molds. Further more the truck or track system is of benefit in that after casting and hardening of the metal the truck may be moved over a pit into which the castings are discharged when the molds are opened by extending the lazy tongs in the manner above described. If desired the truck may be moved over a hot or cold duct, not shown, where the molds may be heated or cooled as desired depending upon circumstances, the character of the work, the nature of the castings and other considerations.
From the foregoing description and a study of the drawings it will be apparent that I have thus provided a very simply constructed and easily operated multiple mold of one type by means of which a large number of castings may be produced in the minimum time and with the least possible effort so that production may be greatly increased and labor expenses reduced.
lVhile I have shown and described the preferred embodiment of the invention, it should be understood that the disclosure is merely an exemplification of the principles involved as the right is reserved to make all such changes in the details of construction as will widen the field of utility and increase the adaptability of the device provided such changes constitute no departure from the spirit of the invention or the scope of the claims hereunto appended.
