Application filed March 13, 1913.
T0 (6Z5 whom it may concern:
Be it known that l. Tnomas HEXRY Mc- Fnnnnx, a citizen ofthe United States, residing at Mecca, in the county of Parke and State of indiana, have invented a certain new and useful Improvement in Molds, of which the following is a full, clear, concise, and exact description reference being had to the accompanying drawings, forming a part of this specification.
liiy invention relates to dies -for making coping. and has for its object the provision of such die which can he used to form three pieces of single slant coping with one operation. the three of course, being fastened together as the are formed in the die. but arranged in such a manner that incisions are provided at the time of forminn: at which incisions the three-piece product may he very easily separated to resoli'e it into its three individual pieces oi single slant roping. ll itii 'tlic coping thus formed of three ection in the PFC-(:45 cl makins' l have a structure which ran he rery readily placed in the kiln to be fired with little atten ion. a d this is grea .lvantajie 22 the two pier-rins: sections r. n placed in iliv lzi n i1 in: coil very rlosc to- ;reiher to ament thorn iron: falling and in 4 i n ilrat't "i of? tr i i not he :inisio lo 1; and thus oul .4 e dullfhif ent in too or four cop- Y is ln f arv to use a wire s ri her: over a how to separate the finished section. from that rr-nazinin in the die. thus man one and onohali to two inches the die which has to pulled out h the hands oi the ope'ators, occasioning thereby several minutes delay after making each section of coping.
I also find that coping made from four piece dies has not enough slope to it tomake a good marketable article. Further in making the two piece sections the bell is at tached to the die by bridges which very frequently bend so as to disarrange the position of the bell, thus causing the coping either to break or warp in drying due to the difference in the thickness of the clay. This warping is always in one direction and Specification of Letters Patent.
Patented Nov. 16, 1915.,
Serial No. 753,913.
as the coping will not reverse when setting in the kiln to burn, thus the article is unhairs of the two and four piece sections and I will explain one form of die which I utilize in forming these sections through the aid of the acconipairving drawings illustrat ing the same in which Figure 1 is a sectional View of a die con structed in accordancewith my invention; Fig. 2 is a top View of a fixed three piece section of c ping: Fig. 3 is a sectional view on line 0 of 1: l a perspective View of a single slant coping unit. and Fig. 5 is a bottom View of the former plate Referring more particularly to Fig. 1, I show a hell 1 forming part of a die and which is placed interior-l of the die elc ment The element 2 is securely bolted to the mud cyli er oi a steam clay press in any manner desired and the hell 1 is snitalol held upon a rod 3. which rod bears l. ainst the hell through the interposition of The washer T has a very o are and prevents its shitting .nahle extent. A suit-ride nut e parts tog tin-r to I illili rigid rtine, not shown. A sin: o extends throu 'h the ce ter of the bell and carries a knuckle joint 8 so in a cl: hwise direction w; d to throw the :niie 7 out wardly after 1e former plate 5 has been ll'lOYQil from the position occupies in Fig". 1. thus to p rmit. cutting of i protruding extreinitfv oi the material issuing forth out of the orifice l0 IHOw'lCiQCL between the hell -1 and the element 2. As the shaft 6 is turned in a contra-clockwise direction. by reason of the knuckle joint 8, the knife is withdrawn into the position shown in Fig. 1. A dowel that turning 1 and 4 to holc them together and to pre- 5 holds rent the hell 1 from turning. The former" I plate 9 is adapted to more downwardly in the path of the arrow as indicated in dotted I lines at 12 as the material is being forced out through the orifice 10. Initially the former plate 9 is held in position within element 2 by a three arm spider 19 engagclearly in Fig. 4:.
In order to be sure that the entire space is filled, small bleed holes 15 are provided which'permit the air to be forced out from this space'as the material is forced in. Afte the space, has been entirely filled the spider 19 is disengaged from hooks 18 permitting the former plate to be carried downwardly upon a rod, not shown, thus allowing a section'of coping to issue from die and mold. The finished product then has the appearance as shown in Fig. 2 in which three pieces of coping, respectively 16', 16, 16 are shown as forming a section of three units. At the points 17 small incisions are provided as the material passes through the die, at which'points the three sections 16 may be broken, after firing, into their three component units. It will be seen that a three section unit readily stands up and thus can be easily handled during firing.
From what has been described it is thought the nature of my invention will be readily apparent.
- Having however, thus described one form which my invention may take, what I claim as new and desire ent is:
to secure by Letters Pat- A mold for multi-section coping units,
coping as shown more.
- sided cooperating die element for said bell,
the two elements forming an orifice to accommodate three coping units so that the longer wall of one coping unit adjoins and is'united to the shorter wall of the other coping unit, and three pairs of V-shaped scoring elements fastened to said bell opposite to the jointure of the coping units so that the three pairs of scoring elements alone form three parts of restrlcted crosssection whereby when sa1d multi-unit sec tion is withdrawn from said mold, the incisions made by said scoring elements and the acute angled incision due to the adjoining walls provides portions of restricted cross-section to permit separation without waste, said scoring elements of each pair' being opposed and making incisions of substantial cross-section.
In witness whereof, I hereunto subscribe my name this 12th day of February, A. D.
