MOLD FOR VAULT-LIGHTS.
SPECIFICATN forming part of Lettersl Patent No.. 404,765, dated June 4, 1889.
Application filed June/8, 1888. Serial No. 276,487. (No model.) l
To all whom, it may concern: v
De it known that I, DAVID BAR'KER, a citizen of the United States, and a resident of Canton, county of Stark, State of Ohio, have invented anew and useful Improvement in Molds for Vault-Lights, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specilication.
My invention relates to improvements in molds for making' vault-lights; and it consists of the hereinafter-described mold and of the detail and combination of parts, as -set forth in the claims, the object of which is to facilitate the molding of vault-lights and to great-l y reduce the cost.
Figure l is a side elevation of the mold, showing the parts in normal position; Figj, an elevation of plunger and a sectional view of fountain and upper portion of mold. Fig. 3 is a plan view of the body of the same. Fig. 4 is a sectional view of the bottom portion of the mold; Fig. 5, a plan view of same;
Figo, same view of mold-clamp; Fig. 7, a view of an eccentric locking-pin and a portion of the handle; and Fig. 8 is a view in perspective of the light.
Similar letters of reference indicate corresponding parts in all of the figures-in the drawings.
A represents the bottom of the mold, in which is provided a series of circular apen tures B, having a countersink about the upper portion to form the under side l) of t-he projected head portion a of the light L, and about the upper portion of said part is provided an annular rib D, flat or plain on the top, as shown at d, and beveled O11 its lower side, as shown at f. In the face of said portion A is provided a recess E, to receive a downwardly-projected portion F of the upper portion G of the mold, and in the bottom of saidportion A is provided a recess H, in which is fitted a circular plate I, to which is secured a series of plungers J, adapted to the apertures B. The 'upper portion of said plungers being out away to a line of about forty-ve degrees, as shown at M, Fig. 4, to form the reflectingf-ace N of the light L, the said recess H should be at least one-half inch deeper than the thickness of the plate I, and the parts assembled about as shown in Fig. 4. The upper portion G of the mold, having its lower face adapted to the recess E in the bottom portion A of the vmold,'as hereinbefore stated, is also provided with a series of depressions, as K, corresponding with the apertures in the bottom portion Ato form the top or head portion a of the light L, as shown in Fig. S, and also with a centrally-located. aperture O as a fountain, with which the depressions K are connected by a communicating sprue P, through which the fused glass is forced by the descent of the plunger J into the mold formed by the depression K in the top portion and the aperture B in the bottom portion. About the top portion G there-is also provided an annular-rib Q, similar in form to rib D about the bottom portion A.
A c`a`np R is formed substantially as shown in Figs. 1 and 6, consisting of two semicircular portions S and S', pivotally secured together, as shown at T', part S having at its free end two ears g and g, and portion S a single ear h. Each of said ears is centrally perforated, as 7n c.' The perforation la in the ear g is smaller than perforation le in ear g, and is adapted to the smaller portionl of the eccentric locking-pin U, the eccentric portions m being adapted to the perforation k.
On the inner face of the clamp so formed there is provided a V-shaped groove, as indicated by the dotted lines WV, adapted to embrace the ribs D and Q, resting on the beveled faces f and n. To secure the parts, the` locking-pin U is placed in the perforations in the ears referred to, and is rotated by the handle X into a locked position, the parts being held in registered relation by the dowelpin y in perforation y', and together by the pressure of the clamps on the beveled face of the ribs D Q.
The operation is as follows: The mold is clamped together, as shown in Fig. l, the plunger Z removed, a desired amount of fused glass is dropped into the fount O, the plunger returned, and the mold placed under a press adapted for such purpose, the plunger forced down, and the fused glass driven through the sprues P into the mold formed by the.aper
IOO
l. In a vault-light mold, the combination.
of' the bottom part A, having; a series of perforations B, an annular peripheral rib D, re-
lI, and a bottom plate I, having; a series of plungers J secured thereto and adapted to enter the perforations B, said plungers out away at the upper portion to a line of angularity of about forty-tive degrees from a line drawn vertically through the @enter ot' the plungers, substantially as described, and for the purpose set forth,
2. Ina vaultlight mold, a top portion G, having a series of depressions K, a central fount,as O, and commu noating,` sprues P, and an annular rib Q, substantially as described, and for the purpose set forth.
3. The combination of the bottom portion A,having a series of perforations B, recess ll, plate. I, plungers J, annular ring D, a top portion G, having depressions K, sprues P, t'ount t), annular peripheral rib Q, plungers Z, and looking-clasp R, Substantially as described, and for the purpose set forth.
In testimony Whereot` I have hereunto set my hand this 1st day of June, A. I). 1889.
DAVID BARKER.
