'ECKARDT v. nsKEsEN, or NEW YORK, N. Y.Y
MOLD non DUMMY Anninl. BoMBs.
To all lwhom t may concern.'
Be it known that I, EGKARDT V. EsKE- SEN, a citizen of the United States, and a resident of New York, inthe county of New York andState of VNew York, have invented certain new 'and useful Improvements'in Molds for Dummy Aerial Bombs, of which the following is a specification.
My present in vention relates generally tomolds for plastic' material, and more vparticularly' to a mold for forming dummy aerial bombs of terra cotta, the clay for which maybe dumped in measured or weighed quantity within the mold and by means of pressure forced readily and quickly `tothe desired shape without the difficulties and' delays incident to known apparatus for this` purpose. Y
i The primary' object of myinventionis thereforejthe provision of a quick acting effective apparatus for this purpose as well as one'which will be ineXp-enslve mit nature In the accompanying drawings .illustratf ing my present' invention, Y
Figure 1 is a vertical longitudinal section through a mold constructed in accordance withY my invention under maximum pressure,
Fig. 2 is'a horizontal section taken longitudinally through thevmold,
Fig. 3 is a vertical longitudinal section with both of the mold parts elevated,
Fig. 4 is a vertical transverse section with the parts in the position shown in Fig. 1, and
Fig. 5 is a similar view with the shown in the position of Fig.' 3.
Fig. 6 shows `a somewhat different construction.
' Referring now to these figures, my invention proposes a mold including a rectangular mold case 10, the'side walls 11 of which have a series of openings 12` opposite one another and adjacent to one end, for the reception ofpins or plungers 13. The mold case 10 also has its end walls 14 provided with openings 15 for the reception-of a rod or stem 16, the opposite ends of. which project beyond the end walls 14 and one end of which may have a handle 17 for convenience in the insertion of the rod or stem within, and its removal from, the mold case. j The mold itself is in two sections, a lower section 18, and an upper section "19, each parts of an external shape and size to slidably Specification of Letters Patent.
` intert the interior of the mold'case 10, and
site the openings 15 of the mold case end walls 14 so that the rod or stem 16 may extend axially through the mold space formed by the opposing cavities 21 of the two mold sections cut within their 'adjacent faces, land when ltogether forming a contour or outline of the article'to bemolded.
Patented Mar. 11, 1919.`
Application filed AugustlS, 1918. Serial No. 248,967. v i Y Y f Both of the mold sections 18 and 19Ihave vprojecting lugs 22 'therein adjacent the smaller end ofthe mold space or cavity andV have their side edges recessed asat 23,. the recesses when together forming openings lopposite the openings 12 of the mold case side` walls 11 so as to permit the pinsor plungers 13 to project at their inner ends into the mold space or cavity as seen in Fig. 2.
The lower mold section 18, which is supported vupon any suitable surface forming the base ofthe moldcase, is elevated at the end of eachmoldng operation by means of an elevating plunger A24 engaging itsvlower surface at apointv substantially midway between ts ends and the upper mold'section 19 is both lowered'and raised bya'power screww25 which engages itsupper surface Y substantiallymidway between its ends and l whichin practice is connected to any suitable' source of power for'forcing the upper Y mold section downwardly 4to the required pressure and elevating the same after such pressure has been released and the clay is forced to completely'fill the mold cavity.
The pins or plungers 13 are pivotallyconnected at their outer ends at 26 to intermediate points of sideV levers 27 in turn pivotally connectedat one end as at 28 to lugs 29 projecting from the sides 11 ofthe mold case and having handles 30 at their opposite ends.
In operation, the plunger 24 is lowered to permit the lower-mold section 18 tobe seated downwardly within the mold case 10 and when so seated it is obvious that the rod or stem 16 may be thrust through the end wall openings 15 of the lower case, across the upper portion of the lower mold section 18. The levers 27 may at thesametime be moved inwardly so as to thrust the pins or plungers 13 Vinto the position shown in Fig. 2, after which the desired quantity of clay or other Vsuitable plastic material is placed within the lower mold section and the upper `mold section 19 1s lowered until the maximum pressure'is reached against the lower section. This vpressure serves to force the clay or other plastic material to= completely' fill the mold space as desired, and subsequent to release of the pressureitheupper section 19 may be elevated and, after the rod or stem 16 has been withdrawn 'longitudinally through the mold form and the molded form from which the rod has been withdrawn,' so that the article may be levers 27 moved outwardly to withdraw the pins or plungers 13, the lowerinoldsection v18 lmay be elevated by the elevating plunger 24C so as to raise the molded article to a vpoint level with or-higher thanfthe.
walls the mold case 10. Any suitable bar or like implement may thenbey passed through the core or axial opening of the shown vin Fig. 3 ffor thereception of theV rod'16,' su`ch opening may bea fslot extending to fthe upper end of theend plate v14,
' as shown'infFig 6 of the drawing.
I claim: Y 1. ,A mold of the character described c0111- prising superposed mold sections forming a saidniold sections are movable vertically,`
liaving'sideV and-end openings to register 'with' the side and end openings of the mold -sections,-a rod for insertion longitudinally within the mold cavityY through Y the end openings, andvr transverse plungers shiftable in the side openings, as described. 4
2. mold .of the character described. comf i prising superposed :mold Vsections forming a mo'ldacavit'y therebetween yand having'v recessed Aside and end portions, vforming side and end. openings, a mold casein which the sai'dfinold sections lare movable vertically,
:having side and end vopenings to register with theside and end openings of the vmold sections, plungers in the side openings, a rod for insertiony longitudinally within' f the mold cavity'through the endopenings, and levers pivoted at the'sides of the mold casegand to-whicli thesaid plungers are connected,.as described. i
3. A mold of the character described coing prisiiig fw.superposed mold sections formingV a mold cavity therebetween, and having recessed. end `portions forming, when vtogether, endopenings, a mold case in whichl the said mold sections are movable ,vertii fcally, having openings in its end walls arranged to register witlitheend openings of the mold sections, v.and Ya .core ro'd Vmovable within and 'from themold cavity through the said endepeningsof the case and mold sections, as described.
