UNITED STATES, PATENT OFFICE 2,545,210 CORE ASSEMBLY FOR CLAY MODELING George W. Moore, Hollis, N. Y. Application April 26, 1949, Serial No. 89,754

2 Claims.

This invention relates to an armature set and more particularly to anarmature set which may be readily assembled and disassembled and in which the core forms are readily interchangeable and replaceable. I

In modelling or sculpturing figures and similar articles of clayor plastic materials, it is desireable to utilize a core of relatively stiff material as a support for the modelling material during the process of forming the article and for the article itself when formed. Such cores require support during the modelling process which is advantageously furnished by an armature. 7

It is an object of this invention to provide an armature set which may be readily disassembled for shipment or storage and which may be simply and efiiciently assembled when desired for use.

It is a further object of this invention to provide anarmature set wherein the height of the modelling core and the radial position thereof with reference to its base may be adjusted as desired.

It is'an additional object of this invention to provide an armature set wherein the core elements or assemblies are so constructed as to be readily interchangeable and replaceable permitting the same armature to be utilized for the support of a large variety of core assemblies and wherein the completed model may be readily removed from its armature support.

Other and further objects, advantages and features of this invention will become obvious or will otherwise be made clear from the following specifications and claims appended thereto in addition to the accompanying drawings wherein:

Figure 1 is a perspective view of the armature set in an assembled form showing the core assembly in position,

Figure 2 is a front elevation of a core assembly adapted for use in modelling a human figure;

Figure 3 is a cross section of the supporting collar of the core assembly taken along line 3-3 of Figure 2, and

Figure 4 is a cross section of the armature set without a core assembly, along line 44 of Figure 1.

Figure 1 illustrates the complete armature set in assembled form. The device comprises a base H, which may be of wood, plastic or metal and presents a substantial base surface upon which the device is supported. As more clearly appears from Figure 4, base II is provided with a transverse aperture [2 which is adapted to receive a bolt or stud [3 which is of sufiicient length to extend above the upper surface of the base.

The portion of the bolt extending above the base is provided with threads. Surrounding the portion of bolt l3 extending above base II is washer M which forms a bearing surface for the abutting end of tubular standard [5. Threads are provided on the interior surface of standard l5 for separable engagement with the threads of bolt I3. Transverse perforations 16 are provided in the lower end of standard I5 through which crosspin I1 may be removably inserted to be used as a lever for the purpose ofsecuring the standard in place during the assembly of the armature set. The upper end of standard 15 is provided with a threaded perforation l9 through its wall which is adapted to receive thumbscrew l8 for the purpose offixing the position of supporting column 20, as will moreclearly appear hereafter. Supporting column 29 is of a cross section adapted to be telescopically received within standard I5 and may be selectively positioned therein by tightening thumbscrew l8 against its surface. The upper portion of supporting column 20 is provided with a laterally extending -supporting arm 2| normal thereto, which terminates in perpendicwfigure to be modelled and its posture or position.

For illustrative purposes, a core suitable for use for the purpose of modelling a human figure is shown. It will be understood however that this invention is not limited to such figure and may be employed in a wide variety of configurations. An additional advantage in twisting the wire has been found to be that it provides a suitable surface for the adherence of such modelling materials as clay thereto.

In the core illustrated, three independent sets of such twisted wires are utilized and brought to a common point or juncture 24. As more clearly appears from Figure 3, collar 25 secures wires 26' at their juncture by means of sleeve portion 21 which surrounds the wire and frictionally retains them in position. Collar 25is additionally provided with socket portion 28 which is adapted to separably receive perpendicular post 22. The modelling core assembly 23 is formed as a unit and comprises the wire 26 forming the core for the particular figure to be modelled to which collar 25 is permanently secured and retains the wires in sleeve 21 thereof.

When it is desired to erect the armature set,

bolt I3 is inserted through transverse aperture tightened against the column at the desired.

height and in the desired radial position of supporting arm 2 I.

The armature set is then in condition to re- .ceive a modelling core assembly appropriate for the particular figure to be modeled. In order to position modelling core 23 on the armature it is merely necessary to insert perpendicular post 22' in socket 28 which is provided on the modelling core assembly. It should be noted that in spite of' variations of wire size, the number of strands and disposition o'bviously made necessary in order to provide cores for varying figures, each of the figures need merely be provided with a socket It may be understoodthat the collar may be secured carrying collar adapted to receive post 22.

to any portionof the-wire forming the core although it has-been found advantageous to secure it at the juncture of wires inorder to eliminatethenecessity of additionally fastening means on the Wire and to provide proper balance. It will also be seen that the collar may be utilized tosupport modelling cor-ematerial other than wire. Upon the completion of the model it maybe readily removed frompost 22 and the armature used to support another core for theformat-ion of other models. In this manner an arrangement is provided in which the armature may be used'any number of times'by the substitution of core assembliesas desired.

1. have here shownand described apreferred embodiment of my invention. It will be pparent',v however, that this invention is not limited to this embodiment and that many changes, ad

dition's and modifications can be made inconnection therewith without departing from the spirit and scope of the invention as herein disclosed and hereinafter claimed.

Having described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A core and collar assembly for forming models of plastic material comprising a base, a tubular standard separably supported by said base, asupporting column telescopically received within said standard: and provided with a laterally extending supporting arm and a perpendicularly extending post, a wire core form assembly adapted to be surrounded by and support a plastic material tobe modelled thereon, said core assembly being formed of twisted wires and being surrounded by a collar formed With a sleeve portion and asocket portion, said sleeve portion being adapted to receive and support the wires forming said core and said socket portion being adapted to separately receive the perpendicularly extending post, whereby said core and collar assembly isseparably supported by said standard said col"- la-r upon separation forming'part of the modelled product.

2. A core assembly for modelling material comprising a base; a supporting standard carried by said base; apost carriedby said standard, a; wire core and collar assembly to be'surrounded by and to separably receive said post, said collar upon separation from saidbase forming part oi the modelled product.
