MANUFACTURE OF WALL COPING.

SPECIFICATION forming part of Letters Patent No. 313,583, dated March 10, 1885.

Application filed August 28, 1884.

- of Toronto, residing at Toronto, in the county of Jefferson and State of Ohio, have invented certain. new and useful Improvements in the Manufacture of Wall-Coping; and I do hereby declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings,and to letters orfigures of reference marked thereon, which form a part of this specification.

My invention has reference to the manufac ture of wallcoping and similar articles of terracotta; and the said invention consists in the improved method, hereinafter described, of molding said coping, and in the improved molding device hereinafter fully explained.

In the accompanying drawings, forming a part of this specification, Figure l is a plan view of the improved molding apparatus employed by me in carrying out my invention, the former being removed; Fig. 2, alike view illustrating the improved molding apparatus opened for the removal of the coping after it has been formed. Fig. 3 is a section on the dotted line 00 00, 'Fig. 1; Fig. 4, an inverted plan of the former.

Heretofore in the manufacture of coping it has been common to mold the same in individual sections, which,when arranged for baking and drying,would readily warp under the action of the heat. By my improvement I overcome these defects and objections by producing at a single molding operation two coping-sections joined together to present an oc tagonalshaped article which can be baked and dried without danger of warping and can, after such baking and drying action, be readily severed to present two coping-sections.

The mold employed consists, essentially, of a base section, A, having a central vertical core, B, the outer sides of which approximate the shape of the article to be anolded, and are provided at each end portion with a vertical angular rib, a. Avertical recess, 1), is formed in the core B about midway of each side, as illustrated most clearly in Figs. 1 and 2. The core B is provided centrally near each end (No model.)

with vertical perforations 0. Two jaws, O D,

are hinged together on the baseplate A, opposite one end of the core B, and the said jaws are of such shape and configuration as to conjointly form on their inner faces the outer moldsurface for the double coping to be formed.

As seen in Fig. 1, the said sections 0 D,when folded together, leave a space, E, between themselves and the central core, B. The forward portion of each section 0 D is provided with a tongue, d,which,when the said sections are in the position illustrated in Fig. 1, lie parallel beneath a loop device, 6, formed on the base-plate. The tongue (I of the section 0 has pivoted thereto a lever, F, having at its frontpivoted portion a square loop, f, which, when the two tongues are adjacent, as before referred to, is adapted to take over thetongue of the section D and lock the two sections rigidly together.

G refers to the former or head of the mold, which is provided on its under side with a graduated series of shoulders and a bottom portion, 9, which coincides in shape with the face of the core 13, and is provided at either side of the center with lugs lnwhich are adapted to enter the vertical perforations c of the core and prevent any movement of said head relative to said core. Lugs 6 project laterally from the sides of the said former G, near each end portion thereof, and are designed to engage ears j on the sections 0 D, to hold said head in position when the sections 0 D are locked, andpreventthe said head from dropping out when the mold is inserted.

In forming the improved coping the clay is first worked roughly into the pattern indicated by in Fig. 2, which is placed over the core,

so as to rest upon and be supported by the base A of the mold, after which the jaws O D are brought together andlocked with the head or former G between them.

The closing and locking of the jaws result incompressing and forcing the clay pattern against the core B, causing a portion of the pattern to enter the recesses Z) in each side of said co're,to form the coping-rib, and additionally resulting in the angular ribs a at each end of the core penetrating the pattern sufficient to render the finished article frail and easily severed at said points. It will, however, be

it to be passed through the various drying I finally capable of being readily and baking operations without liability of breakage, and further, to resist any tendency of becoming warped by the heat in the latter operations.

After the article has been formed, dried, and baked, a blow or shock will suffice to cause it to sever at its ends into two complete coping-sections.

From the foregoing it will be apparent that by the herein-described improvements two sections of coping or like articles of terra-cotta manufacture are readily molded together in one operation, and so formed as to permit of their drying and baking without warping, and severed into two complete'and finished sect-ions.

vI am aware that previous to my invention it has been proposed to mold a clay pipe or cylinder and form longitudinal grooves or channels insaid pipes previous to burning the article, so that alter such burning operation the I pipe or cylinder could be severed, so that access could be more readily had to the interior of said pipe.

My invention will be readily distinguished from the above, in that I mold a single article composed of two complete coping sections capable of being burned conjointly, and afterward separated, to enable each part to present a complete coping-section.

I. claim- 1. The improved method herein described of manufacturing coping, the same consisting of molding two complete coping-sections to gether in a single article, drying and baking said article, and finally severing into two com.- plete coping-sections, sustantially as set forth.

2. The improved method herein described of manufacturing coping, the same consisting of molding two complete coping-sections to:

said reduced end portions into two complete copingsections, substantially as set forth.

3. The combination, in a mold for the manufacture of coping, of a central core of a shape adapted at each side to form the inner portion of a coping-section and outer clampsections interiorly shaped each to form the outer portion of a coping-section, substantially as set forth.

4. The combination, in a mold for the manufacture of coping, of acore of a shape adapted at each side to form the inner portion ofa coping section, outer clamp-sections interiorly shaped, each to form the outer portion of a coping-section and a head or former, substantially as and for the purpose set forth.-

5. The combination, in a mold for the man ufacture of coping, of acore shaped to form at each. side the inner portion of acopi'ng-section, and having angular ribs a at each end, and outer clamp sections interiorly shaped each to form the outer portion of a coping-section, substantially as set forth.

6. The combination, in a mold for themanufacture of coping, of core B, sections 0 D, hinged together at one end, shaped as (16'. scribed, and devices for locking the free ends of said sections, in the manner and for the purpose specified.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN FRANOY.
