Application mea July 27, 1914, seriai No. s'ssaesi 'Rw'd october 12, 1917. serial No. 196,347.

To all 'whom t may concern Be it known that I. JAMES T. WIsNnn, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Molding Apparatus, of which the following is a specification.

This invention relates to apparatus for forming hollow articles, such as flower pots, tubs, and the like, of such materials as con crete, for instance.

The object of the invention is to provide an apparatus for the purpose described by the use of which such articles may be molded or formed with great rapidity, and which is characterized by extreme simplicity of construction and operation.

Other objects and aims of the invention, more or less broad than those stated above, will be in part obvious and in part specifically referred to in the course of the following description of the elements, combinations, arrangements of parts, and applications of principles constituting the invention; and the scope of protection contemplated will appear from the claims.

In the accompanying drawings, which are to be taken as a part of this specication, and in which I have shown a merely preferred form of embodiment of the invention, Figure 1 is a view in central vertical section, with parts broken away, illustrating the invention, and showing in dotted lines the alternative positions of certain of the parts; Fig. 2 is a sectional view of Fig. 1 trans versely therethrough; Fig. 3 is an elevation of a four-part eXpansible and contractible shell, which may be employed in connection with the invention, and Fig. 4 is a plan view of the same.

Referring to the numerals on the drawings, there is shown at 5 a stationary support or platform, upon which rests what may be termed a filler block 6, which is preferably solid and of any desired material appropriate for the purpose for which it is to be used. Surrounding the platform 5 there is a vertically movable platform 7, which is raised and lowered by means indicated by the rods 8. The vertically movable platform 7 is intended to support a shell 9, the outwardly turned flange 10 of the shell resting upon the platform, as shown, and the filler block, which is supported by the platform 5, being adapted to lill up the interior of the shell and support the same. In use the block 6 remains constantly in position upon the platform 5. A shell 9 is placed over the block, as indicated in Fig. l, and with its edges resting upon a movable platform 7, which latter is in the full line position of Fig. 1. The concrete or other plastic material is now molded into shape upon the outside of the shell 9, the filler block effecting the necessary support for the hollow shell while this operation is going on and preventing any distortion of the relatively thin metal shell. When the shaping operation is completed, the mechanism for elevating the platform 7 is set into operation and the platform 7, carrying with it the shell 9 and the formed article 11, assumes the position shown in dotted lines in Fig. 1, whence it may be taken to some other point and left to dry, while the platform 7 resumes the full line position shown in Fig. 1, ready for another shell and another molding operation.

In order that the shell may be rendered adaptable for the making of articles of considerable range of size and proportions, I prefer to make it of

sections

14, 15, 16 and 17, as indicated in Figs. 3 and 4. The

sections

14 and 15 slide longitudinally upon each other, as do also the

sections

16 and 17, while the

sections

14 and 16 have also a transverse sliding movement, as have also the

sections

15 and 17. The result is that the shell is expansible and contractible in both directions.

`Inasmuch as many changes could be made in the above construction, and many apparently widely different embodiments of my invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in *the accompanying drawings sha-ll be interpreted as illustrative and not in a limiting sense.

It is also to be understood that the language used in the following claim is intended to cover all the generic and specific features of the invention herein described form, a shell Covering the filler block and and all statements of the scope of the invenhaving its edges resting upon the vertically tion Which, as a matter of language, might movable platform.
