SPECIFICATION forming part of Letters Patent No. 678,458, dated iJ'uly' 16, 1901.
Application filed June 30, 1900- To all whom, it may concern:
Be it known that I, OWEN DALEY, acitizen of the United States, residing at Lyons, in the county of Clinton and State of Iowa, have invented certain new and useful Improvements in Knobs; and I do hereby declare that the followingis a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.
My present invention relates to knobs; and it consists in the novel features of construction and operation hereinafter pointed out in the claim.
In the drawings accompanying this specification and forming apart thereof I have 1.shown suitable means whereby the invention may be produced and have illustrated the various parts of my new knobs.
In the drawings, Figure 1 is a sectional view of a suitable flask with the various parts of a knob assembled therein. Fig. 2 is a section, and Fig. 3 is a bottom plan view of a metallic back shell of the cap or handle portion of the knob. Fig. 4 is a section ofa cast shank and a metallic back or shell united in accordance with my method, and Fig. 5 is a view of a completed knob.
To carry out myinvention, Iprovide a suit- 3o able flask, preferably composed of the parts' a and a, so shaped and arranged as to receive and inclose the back-shell B of the knob,
which preferably will be an ordinary semispherical steel shell provided at its deepest portion with tongues b, formed by stamping the same from the body of the shell in a suitable press. The matrix a of the mold or flask which receives the shell is provided with a suitable depression a of semispherical shape 40 to receive and support the shell B of the knob and in extension thereof wit-h a chamber a, into which the metal composing the shank is run and in which the shank is cast. This chamber may be of any suitable shape and size to conform to the design of the shank, and in the drawingit is shown as circular in cross-section to produce the ordinary round shank. The matrix is also preferably provided with means to receive and support centrally of the chamber a chill or core 0, whose function and office is to form the bore in the Serial No. 22,1 70. .(No model.)
shank. This is preferably done by means of a second chamber a in central extension of the chamber a.
The part a is provided with suitable means for gating the metal of the shank at the part ing of the mold from the inside, of the back B, and this is suitably accomplished by pro viding a suitable gate for the metal, as at the point indicated by the reference-letter a This gate is so constructed as to lead from the parting of the mold into the chamber a, and the part a is formed'at its bottom to provide a space between it and the inner wall of the shell, preferably by being truncated, as at a In practicing my invention the back B is placed in position in the depression or cham her a with its tongues 1) extending slightly into the chamber a and surrounding the core 0, which also is properly positioned. The part a of the mold is then placed within the back B, the parts being assembled as shown in Fig. 1. The metal for the shank is then poured at the gate a which of course extends from *the parting of the mold' into the chamber a, going over the inner face of the shell and down into the chamber a through the opening in the shell made by striking up the tongues 19. The upper portion of the chamber a is greater in diameter than the distance from the outer faces of the tongues, and may be slightly enlarged, if desired, at this point to produce a slight external shoulder at the upper end of the shank. The metal runsinto and fills the chamber, surrounding the tongues of the shell and forming the Wing 01 within the truncated portion of the part a. After the metal has cooled the parts are withdrawn from the mold and the surplus metal within the shell is broken off, a slight projection 61 in the gate at any suitable point reducing its thickness for this purpose, the metal not attaching itself to the side of the steel back orchill B. The core 0 is likewise readily removed, and the product then appears as in Fig. 4, the shank D surrounding the tongues and metal of the shell. The enlargement of the chamber a at its upper end produces a corresponding-shaped exterior enlargement in the shank, as at d, and the formation of the part a produces the interior portion 01. The shell is then finished off by attaching the portion B in any suitable manner now known to the trade.
By casting the steel shell into the shank as a chill in the manner described I am enabled to get a permanent and durable form ofjoint, as the cast-iron incloses the metal of the shell. The gating of the metal from the inside of the shell enables the metal to fill the mold evenly and to eifectually form an internal wing or boss, which keys the parts in place, such as (1, while the shell acting as a chill enables the metal to be broken 0E without attaching itself to the side of the shell.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
A knob consisting of a sheet-metal shell having tongues, and a shank cast about and surrounding the tongues of the shell, and 20 OWEN DALEY.
