MOLDED ARTICLE Filed Sept. s, 1926 Qrwezz Isidore 51h70?? Patented July' 28, 1931 UNITED STATES PATENT OFFICE ISIDORE SIMON, OF CHICAGO,- ILLINOIS uoLDED ARTICLE Application filed September 8, 1926. Serial No. 133,424.

'15 will be obvious to those skilled in the art from the disclosure herein gibv'en.

' To this end my` invention consists in the novel construction, arrangement and combination of parts hereinshown and de- 2o scribed, and ymore particularly pointed out in the claims.

In the drawings, wherein like reference characters indicatel like or corresponding parts:

Fig. 1 is a vertical central section taken through a heel embodying the invention; and

Fig. 2 is a section taken on line 2-2lof Fig. 1.

Referring for the present to Figs. 1 and 2 of the drawings, I have shown one form of the invention embodied in a heel particularly adapted for womens shoes. The heel vformed of a phenolic condensation product, the body portion 10 being provided with inserts 11 and 12 of Awood or fthe equivalent whereby the heel may be attached to a shoe indicated in dotted lines at 14 ,and whereby a thread member 15 may bex secured to the heel. Interposed between the inserts 11 and 12 and preferably extending into recesses 17 formed therein is a tubular member 19 delining a cylindrical pocket 20. In the preferred embodiments of the invention the tubular member 19 is preferably formed. of some metal, such as aluminum, and is preferably of such diameter that the body portion 10 of the heel comprises a relativelysmall amount of material and is therefore relativepreferably comprises a body portion 10I ly light in weight. This is advantageous in that heretpfore attempts to form heels of the kind described from phenolic condensation products have not met with commercial success because of the weight of the material.

By practicing my improved method, the

completed heels are relatively light in weight and may be used with advantage in place of heels formed from wood or metal. An added advantage of my product is the relatively permanent polished appearance of the heels. This largely negatives the need of covering it with leather in any of the embodiments of the invention.

My improved heel is preferably formed in a mold wherein the phenolic condensation product may be subjected to heat and pressure. To prevent collapse of the body portion 10 during the molding process, I preferably employ the member 19 occupying the pocket 20 which may be in the form of a tube, if so desired. It' is readily understood by those skilled in the art that the inserts 11 and 12 together with the tubular member 19 may be placed in a suitable mold and that the phenolic rcondensation product may then be introduced into the mold afterwhich the mold may be closed and subjected to heat and pressure until the phenolic condensation product is cured. 'The amount of pressure to which the phenolic condensation'product is subjected varies with the texture thereof, but it is readily apparent that it may be subjected to a relatively high pressure without failure of the tubular member 19. I may dispense with the tubular member 19in some instances the heel through an opening 22 rovided in the insert 11. ,The heel may then e attached to the shoe 14 by means of screws 24 or the equivalent screw-threaded into the insert 11 andthe tread member `15 may be attached to the heel by means of screws 25 or the equivalent screw-threaded into the insert 12. It is generally unnecessary to color the body portion 10 or to polish it-as the proper colorlng matter may be mixed with the phenollc condensation productv and the pressure to which the product is subjected will impart the necessary polish.

As pointed out above, I prefer 1n some 1nstances to dispense with the tubular member 19 and rely -solely upon a sand core. It is likewise apparent that if desired, I may in some instances employ thetubular member1V 19 and,y in some instances, the sand core. While I have shown the tubular member 19 as substantially cylindrical in form, it is readily understood that I am not limited to such construction but that it may be made to con` form more or less to the shape of the body portion 10.

I have employed the term plastic material -in the claims to include phenolicl condensation products in liquid form.

Having thus described my invention, it is obvious that various immaterial modifications may be made in the same Without departing from the spirit of my invention; hence I do not wish to be understood as limiting myself to the exact form, construction, arrangement and combination of parts herein shown and described or uses mentioned.

What I claim as new and desire to secure by Letters Patent is:

1. A heel of the character described com'- prising a body portion formed of a plastic material moldable under pressure, a nailing insert at the top andbottom of said body portion, and a relatively large metallic tubular member interposed between and in contact with said inserts.

2. A heelof the class described comprising a tubular body 4ortion formed of plastic material, a pair o? penetrable inserts seated in said body portion at the top and bottom thereof, each of said inserts having a substantially annular shoulder seated in said body portion and with one edge substantially flush with the bore of said body portion, and a tubular member of substantially light, but rigid, construe"- tion seated within the bore of said body member and with its opposite edges disposed against the shouldersl of said inserts.

-3. A heel of the class described comprising a tubular body portion, a penetrable insert seated in said body portion at one end thereof, a reenforcing member of substantially rigid material positioned in the interior of saidbody portion in a manner'to/ engage the insert,` said insert having means formed Atherein for securing said'reenforcing member in relatively fixed position with respect to the insert. v,

4. heel of the class described comprising a tubular body portlon, a penetrable insert formed therein for securing said tubular member against lateral displacement with re-- spect to the insert.

In testimony whereof, I have hereunto A signed my name.

IsIDoRE SIMON.
