.Application tiled September 15, 1921. Serial No. 500,849.
Montgomery, in the State of Pennsylvania,
have invented a certain new 'and useful lmprovement in Casting-Ladle Mechanism, of
which the following is a true and exact description, reference being had to the accompanying drawings, which form a part thereof.
My invention relates to ladles adapted to contain and deliver molten metal to be used in castin and has for its object to provide the lad e with co-operative mechanism whereby the metal in the ladle can be maintained at a constant level during the pouring so as to insure a ow of metal from the ladle to the mold of constant volume and velocity,
My invention is especially useful for usey in connection withcentrifu al casting machines of ,the general type escribed in the` German Letters Patent'to Briede, No. 24:2,-
307 of January d, 1912, but has, l believe,
material value for use in other methods ot casting. n
ln my co-pending ap lication tiled September 13,y 1921 Serial o. 500,331 l have described and claimed an improved casting machine of the general type of the Goan patent above mentioned and comprising, amii'g other devices, a pouring ladle stationary during pouring and in' which the metal is maintained at a constant level and t0 by which the result is obtained. My present invention relates to a special construction of mechanism for maintaining the constant level of metal in the ladle and, broadly speakin it consists in providing a pouring adapted to ea tive ofthe amount ot metal f.. gin the ladle.
The nature of my invention be t understood as described inlcoection with indicated at e".
the drawings in which it isillustrated and in which- Figure 1 is an elevation partly in section showing one form of mechanism embodying my invention. l
Figure 2 is a similar elevation showing vthe samev mechanism illustrated in Fig. 1 for moving the displacement body but applied in this case to a tilting ladle, and
Figure 3 isa similar elevation showing the application of my inventionto a bottom pour ladle and the use in connection thereveo with of a `float with mechanism controlled.A
bly a lloat for regulatin the movement of t e displacement body in accordance 4with the rate at which metal is withdrawn from the ladle. l
A., Fig. 1, is a stationary ladle having a pouring spout indicated at A. B isa displacement body extending into the ladle and supported by a vertically movable arm C guided at C on a guideway D of an upwardly extendin D. C indicates a t readed hole in the arm C in which is screwed a vertically threaded shaft E actuated through a worm wheel E" and shaft F by a motor indicated at G.
The mechanism shown in Fig. 2 is generally similar. The ladle however, is a tilting ladle indicated at H7 having a pouring spout H and trunnions H2 by which it is supported on'standards ll. When it is desired to pour from this ladleit is tilted, as shown in full lines in Fi 2, bythe lever arm J attached to rock s aft J having an arm J4 which is pivctally attached at la to a link l5 vand attached to ladle at' J2 forming a toggle joint which when straightened out, as shown in the drawing, tilts the ladle to a definite degree and holds it in fixed osition. v
In ig. 3 the ladle, here indicated at K, is a bottom pour ladle having an outlet K for the metal, which is` opened and closed by a stopper L which, as shown, is connected throu h an arm L' with a vertical vslide L* Iheld l1n guideways K2, K, and actuated to raise the stopper to a denitey degree and lower it, by means of the toggle links 2, t? pivoted to and connected by controlling rod in rig. e, n is a aan pany immersed in the melted metal in the ladle K .and supstandard indicated at ported on a standard M extending up from the ladle through the parallel motion device consisting of the lever M2 pivoted to the standard at4 M and connected to the float byplink M7 to which is also pivotally attached one arm of a lever M4, M5, pivoted to the standard at M3. The outwardly extending arm M5 of this lever is connected by a connecting rod O and lever arm O with a control valve O2 by which fluid under pressure coming, for example, from the pipe P is directed at will through the pipes P and P2 to the opposite ends of the cylinder Q in which works a piston Q having a piston rod Q? attached at C3 to the arm C In the construction indicated in Figs. 1 and 2, it is obvious that the motor Gr if run at constant speed will impart a uniform descending motion toy the displacement body B with consequent delivery from the ladle of av uniform stream of molten metal and with maintenance in the ladle of a uniform level.
Referring to 1F ig. 3, it will also be obvious that the float N and connecti mechanism actuated by the float can be util1zed to bring about a downward motion of the displace- Meana@ l. In combination with a casting ladle, i
means for maintaining a constant level of the luid metal in the ladle consisting of a displacement body and means or moving said body into the ladle as metal is Withdrawn therefrom.
2. ln combination with a casting ladle means `for maintaining a constant level of the fluid metal in the ladle consisting of a displacement body, means for moving said body into theladle as metal is withdrawn therefrom, a oat on the metal contained in the ladle vand means operated by said oat for controlling the mechanism actuating the displacement body.
