LADLE;

it To all whom-it may concern: Q Be it known that I, Josnrr V.Biim Aun,

NITED szrATEs PATENT curios;

Josririi v. BBETAUD; or PHILADELPHIA,-BENNSYLVANIA.

a citizen of theRep'ublic of France, residin at Philadelphia, in the county of Phila-- dephia and State of Pennsylvania, have invented certain new and useful Improvements in Ladles, of which the following is a specification.

The present ractice of pouringmoldsin iron and steel oundries, making small and medium'castings, is to fill a large ladle at -the cupola or converter and to empty' itscontents into small shank ladles carried by two or'three men, the pouring proper being thus made by hand. The use of'these small ladles is resorted toon account of the. impossibility to get from a large ladle. a gentle even stream of metal easily controlled, and

i to direct this stream in the mold gate without euttin of the sand or undue spilling of metal. T is is however,- an unsatisfactory 7 method owing to the chilling of metal and formation of skulls on the hand ladles, the

irregularity of the pouriii temperature andconsequently of the shrin age of the'castings, the exhausting character of the work and excessive-heat radiated upon thenien and the expense, of labor. attending to the pouring itself and to the keeping up of hand ladles. 1

The rapid development of the molding machine with its tremendous output has further emphasized the need fora more modern method of pouring eliminating manual work. These consi erations will serve to showflthe newness and usefulness of my improved ladle'liereinafter described.

My invention relates to lip pouring ladles suspended from a crane or an overhead trol-- ley, and the objects of my improvements are rovide'a mediumsized ladle. easily conolled by one man, capable of deliverin a vertical steady stream of metal, theposition of which does not change durin' the tilting of the ladle, with consequent ability of hav- .}ing this ladle filled at the eupola or conset side by side, oscillating around their res'pe'etive lips toward one another, and thus balancing each other in all positions .of

pouring. These bowls are kept. at a proper LADLE.

distance. apart so that their streams unite and further I'use a funnel to give to the resultin stream a uniform size, independently o' the speed of tilting, which funnel also acts as a skimming device.

I have illustrated on the accompanying sheet of drawings, a ladle embodying the producing the tilting of the bowls can be devised. w

Figure l is a front elevation of the ladle before pouring. Fig. 2 is a similar View during the pouring of metal. 7 Fig. 3 shows" the ladle emptied. ,Fig. l is a sideelevation of. the ladle before pouring. Fig. 5 is a detail horizontal section on line 5-5 of Fig. 1, and,- Fig. 6 is a similar'view on line 66 of Fig. 2.

Similar letters refer to similar parts throughout the several views.

The ladle is formed by a supporting frame a, hooked to a trolley or crane chain by the v -above features-although numerous means of s link I). This frame carries two rollers, c and c and has a downward extension. d. The bowls!) and e lined inside with a refractory material are suspended from the rollers 0' by means of the chains f and f, on one end of which are attached the eye bars 9 and g, journaled at h and it on the back of the. bowls. The other end of the chains f and f is connected with thelink 2' which is rigidly fastened to the U-shaped bail j, the link 11 beingguided in the frame extension 01 by means of the rollers v, 'v and w. Each end of the bail j carries a lip spacing member is, one in front of the bowls and one on the back in Fig. 1. These spacing-members act as bearings for the ends of shafts l and Z which are riveted to the bowls underneath their respective lips. Each bowl has thus I three bearings,-one on each side of the li at V Z, on a line perpendicular to the plane 0 the drawing in Fig. l and one central bearing at h on the back. Each bowl. is then in stable equilibrium. The hooks m and m prevent any accidental withdrawing of the shafts 1 from their bearings.

The ends of bail are conneeted by'a light frame 't forming sup rt for a ceii'tral fun iiel or nozzle 'u, which-regulates the size of the stream of metal. The tilting is provided by a pinion a, shaft 0 and hand wheehp I carried by the frame extension the said ing of the bowls.

- It will be seen from-Filgs, 2 and 3 that during the tilting of they adle, the respective centers of gravity of the bowls are not materially raised,. the efl'ort. necessary to tilt them, being consequently very, small. In

this case, the funnel has a vertical downward movement during the pouring.

The ladle being symmetrical in respect to the vertical center line, for every position of the bowls, the center of gravity of the whole system is always on this same line, and the equilibrium is not'disturbed by the tilt lips being conveniently kept apart by time spacing. members k, their respective streams of metal will unite and form asingle stream iilgjays situated on the center line of the The -funnel receives the metal from the bowls and delivers it in a stream of uniform size, irrespective of the speed of tilting of the bowls.

This ladle produces a steady even stream of metal always under perfect control,- and owing to its, positive operation, it can be used to pour the smallest work with ease; The mo ds being lined up under the overhead traveler, one man grasps the hand wheel and proceedsto dothe pouring with" speed and precision by stopping the ladle funnelover each gate, any mg unnecessary. I 7
