METALLUBGIC APPARATUS.

Speciicatiion of Letters Patent. Application flied November 29, 19.09. Serial No. .530,311

To all `tt-:hom 'it may concern: i

Be it known that I, VVILL'IAM'H. PEIRCE,

i a citizen of the United States, and a resident of the city of Baltimore, State of Maryland, have invented certain new and useful Innprovementls in lletallurgic Apparatus, of which the following is a specification.

The invention relates to metallurgie vessels, furnaces or converters that are mounted to turn upon an axis and such, for'example, as are employed Afor bessemerizing copper matte.

.effective mechanism is employed for turning the converter during the course of treatment. andA for securely holding the same in its different positions.

The invention consists in the features otimprovement hereinafter set forth, illustrated in the preferred form in thel accompanyi'ng drawingsand lmore particularly pointed ont in the appended claims.

` cylindrical shell. 1,0'

In the drawings, Figure 1 is a side eleva-v t-ion of the converter with the` improved turning mechanism' applied thereto. Fig. Q is -aiyiew in elevation of the turning-.nicchanism with the converter shell. shown in sec-.

end. If employed for hessemeri'zing copper matte, it will also be provided-With a'set of twyers 19.

The turning mechanism is 'mounted ena v horizontal frame thatv extends t'i'ans'iiersely beneath the shell 1 0. This frame, in the prefel-'red form show-n coriiprises av pair. 'of pai?- allel, horizontal I- eams 20, mounted :upon the foundation 15 and extending beneath .the shell 10 transversely to .the axis .theroofi The beams' 20 :1re connected by a. .series of crosspiec'es 21 secured to their-lower flanges and a series of straps 22 secured to their upper flanges. .it one end,a pair 5fheavy straps 23 are secured to` the'upper Beneath theshell. 10,",1; Ae frame beams are roided a Cross-head guide which, in tie. f orinshoyvn, comprises two cast metal sections; Each of; .these-Seo,- tions is forni'cd ot longitudinallyextending guide-bars 2l connected al;v intervals" by isis' cross-bars that rest. upon-and are Securely riveted to the cross'fbars 22'on the I-beams 2.0.

Couplings 36 are clampedto the opposite ends of the ropes and these couplings are provided with eyes that engage the eyes upon I the ends of a series of tie-bolts 37. These tiebo'lts extend through openings 38 in laterallyV projecting lugs 39 on the opposite end castmg 27 of the cross-head. These openings ilare inwardly, as indicated in Fig. 5, and, at the outer ends of the openings, the inclined faces of the lugs 39 are provided with curved seats 40 that are engaged by similarly shaped Washers 41 on the tie-bolts. Adjust-ing nuts 42 are threaded on the outer ends of the tiebolts andl engave the Washers 41 as shown.

A horizonttil, hydraulic cylinder 43 is mounted upon the cross-bars 23 of the frame in line with ,the cross-head. This cylinder is rovided with a piston 44 having a pistonrod 45 which is rigidly fixed, at its end, to

loneof the end castings 27 of the cross-head.

In the form shown (see Fig. 4), the pist-onrod extends within a socket in the end face of the casting and is secured to the casting by akey 46. Pipes 47 lead from opposite ends of the hydraulic cylinder to a suitable valve casing 48. Supply and exhaust pipes .49 and 50 are connected to thecasing and a suitable valve therein operated by a handlev'er 51 is arranged to connect either end of the cylinder 43 to the supply and the other end to the exhaust, soV that the piston 44 therein can-be shifted in one or the other direction. Or the valve can be positionedto cut off the oppositeends of the cylinder from the supply and exhaust so that the .pist-on 44 will-be securel held against movement by the-liquid in t e opposite ends of the cylinder. i l

The mechanism is extremely simple and efficient and will withstand great strain By Lis means of the hydraulic motor, the cross-head can be shifted back and forth to turn the shell 10 of the converter in one or thelother direction through, the medium of the crossed wire ropes 'The nuts 42 on the tie-bolts i. 37 are vadjusted 'to take up all slack in the.

ropes 31. The piston 44. ofthe hydraulic cylinder is connected directly to the crosshead and, when the flow of liquid to and from the opposite ends of the cylinder is cut off, the piston will be held against movement and,ls1nce there is practically no slack or l'ost motion between the piston and-the heavy converter or furnace shelll 10, the lat-l ter will be maintained with great steadilness in the different positions to w ich it is turned during the operation.4 The cross-head and l' the hydraulic cylinder, in the preferred form, are mounted upon the same frame, so that the cross-head and the iston of the cylinder are properly held in ine, notwithstandin the strani of the ropes upon the cross-hea l'nace or converter and its charge, itcan, b

means of the improved mechanism, be rea ily turned to the different positions as re quired in the course of treatment and steadily held in the different positions. The cur-ved seats'l() and washers 41 form oscillating or ball-and-socket connections between the tie-bolts 87 and the end of the cross-head to allow for the different angular positions of the -ropes as the cross-head is shifted.

The ends of the cross-head and guide therefor, are preferably covered, as shown,

cured at their lower edges to the cross straps 22.

It is obvious that the details of construction set forth can be Widely varied without departure from the essentials of the invention as defined in the claims. i
