IMPROVEMENT IN MACHILNIES FOR SQUEEZING PUDDLERS BALLS.

. Specification forming part'of Letters Patent No. 190,385, dated May 1, 1871 application filed 7 February 12,1877. 1

Buffalo, in the county of Erie and State of New York, have inventedcertainnew and useful Improvements on Squeezers and Ido hereby declare that thefollowingdescription of my said inventiomtaken in connection with the accompanying sheet of drawings, orms a full, clear, and exact specification,,.w'hich will enable others skilled in the art to which it appertains to make and use the same.

This invention relates generally to puddlers 'balhs queezers; and it consists in the combination, with a suitable frame, of three or more ro1lers, so arranged that the space bounded by and includedbetween said rollers shall be tapering or decreasing in size, twoormore said rollers being provided with spiral projections, whose: pitch on each roller shall berarying in relation to that of the remaining roll- .ers, whereby a puddlers ball, introduced into the larger space between said rollers, shall be caused to move forward longitudin ally through said space in such manner that said movement will be a compound rotary, and rectilinear one at the commencement of the action upon said ball, and as the said ball elongates and assumes the shape of a bloomla rotary and forward movement only, all as hereinafter more fnllyset forth and described.

In the drawings, Figure l. is a longitudinal sectional elevation. Fig. 2 is a front, and Fig. 3 a rear, elevation.

Like letters of reference indicate corresponding parts in all the figures. v v

A A A are a series of rolls, made of suitable material, which maybe hardened by any of the'well-known processes, if desired. These rolls are revolved within suitable bearings in' aframe composed of two standards,B B. They are made tapering and hollow, and all, or at least two of them, have on their periphery spiral projections. They are, furthermore, arranged with their axial lines parallel, and with their larger ends opposite each other, so that the space bounded by and included between the adjacent portions of their periphery gradually diminish in size as that of therolls increase. The two lower rollers, A A, rotate in fixed bearings placed the propervdistance apart, while the upper one is adjustably ar motor, &c., .in the usual manner.

to the front standard B is a scoop-like receiviai ea in sliding boxes a,loc'ated in the upper part of the standards B .B,'and;they are rotated from the main shaft Othrough the main spur-wheel D, intermediate gear-wheel E, and the wheels D D E, respectively, the

latter'three being those secured to said rollers.-. g By-their connection in the manner described the rollers A A A f are all rotated lUtfllB same direction.

. Below these rollers is located supplemental'roller, F, having an external contour corresponding to that of the former, except that it is shorter than those, and locatedwith its larger'end opposite the smaller end thereof. This auxiliary roller is revolved by means of the gear-wheel G fromthe gear-wheel Gr! iixed to the main shaft '0, arranged be1ow.said;roller F, and receives its motion from any prime Attached er, H, placed to coincide with a corresponding openingyl, in said standard, The rear standardvB has a similar opening, I, of less diameter than the former, and likewise a correspondingly-reduced discharge-spout, H. Between the rollers A and A and A and A, respectively, are placed shields K, attached with one end to the front standardB. Y e The parts heretofore described are all made of suitable material, and of the proper 8'01 cu gth requisite ina machineof this kind. In operation the action of the same is as follows: 4

' The puddlers ball, as it comes from the 'furnace, is placed into the receiver H, from revolve in adirection with the said rollers,

and, in the commencement of the action of the same, in a direction at right angles thereto,

which movement results in a compound rotary motion of said ball. This result is produced by the helical projections of one or more of said rollers differing in pitch from those of theremaining rollers, or by revolving the same faster, or bya combination of both varying pitch and accelerated speed. In this manner the ball is first perfectly squeezed from all sides and afterward compressed and stretched, and it emerges, from the delivery end of the machine through the opening I in a perfect condition as a round muck-bar.

It will be observed that the rollers are. made tapering, and have their axial lines all paral-' lel. This may be varied by making the rollers parallel and their axial lines converging, which would produce the same result ofmaking the space between the adjacent portions of the rollers tapering, and would, therefore, be a mechanical equivalent of the arrange ment heretofore described. The revolution of the ball in a direction with that of the rollers is, caused by frictional contact'therewith, in combination with the notches z in the-spirals, the forward move-' ment thereof by the spiral pr jections,-aud the revolution at right angles to the plane of the rollers by the varying pitch of said spirals It'is therefore evident that, for simply revolving the ball in a direction .with the rollers, plain or longitudinally-grooved rollers would'answer this purpose perfectly well; but to insure the compound forward move ment and rotary motion, at least one of .the rollers should be spirally grooved; and to produce the compound. rotary and rectilinear motion, two rollers,'at least, must be spirally grooved, and one of these must have spirals of greater pitch than the remaining one. For this reason it is obvious that, while alfthe rollers may be spirally grooved, it is not absolutely necessary that they should be so constructed, but that one may be a plain or longitudinally grooved, and the remaining two spirally grooved, and their pitch made to vary in any one of the manners hereinbefore described. It is furthermore obvious that the diameters of the rollers may be varying with. out interfering with their action. r l In order to deeply indent the ball when first introduced, and in a nearlyliquidv state, and to knead the same thoroughly, and also to assist in the revolving of the ball, and to prevent it from separating on account of'the shifting action of the spirals, these are made of V shape, with their forward or leading side very steep, or nearly at right angles to the plane of the rollers, and on the forward end very high, so as to embed themselves sufficiently into the pliable mass of iron to insure its'being properly worked. For this reason, also, one of the rollers is provided with scores or notches in the spirals, as shownin 'Fig. 2, into which the soft metal forces-its way, forming, as it were, projections, which act, in conjunction with said scores or depressions, in a manner similar to that of cog-wheels, thereby aiding in revolving said ball; but since the ball while advancing becomes more solidified, and therefore capable of better withstanding such action, these scores or notches, as well as the spirals, are made shallower and closer togetherfso as not to feed the bloom too fast, and not to leave marks therein'when it leaves the machine.

To compel parts of the ball detached during the squeezing and kneading process should such take pla'ce notwithstanding the precautionary measures taken in the peculiar construction and shape of the spirals-to reunite, I have located the lowerroller F'in its indicated position, to prevent the detached parts from falling through, and thereby enabling the'mto attach themselves again to the bulk of iron, which, at that stage of the process, is still at a welding-heat, and also to assist in the revolution of the ball, while the sides between the middle and upper-rollers are protected :by shields K to prevent their escape through the space covered bythese shields. v i

c To enable the proper criping of the rollers on varying sized balls, I have made the. up-' per one self-adjusting bymeans of thesliding boxes am said frame- The forward-end of this roller :is allowedto rise and fall freely, and ofitsown,accord,-'so as to adapt itself to the varying; contour of the ball, a lever, N, and connecting-rods? being provided to'lift that endjtbrf a; freeintroduotion of the ball,- But the. rear'endof thisroller should, preferably, be adjusted by means of thescrew B, so as to produce muck-barsof uniformdiameter, the difference-in size of the balls evidencingitself in their length. 3 v

Tokeep the rollers cool during operation, I makethem hollow, and introduce a current of water throughth'e trunnions or bearings thereof by means ofv the pipes S. -To stren gth= on them they are internally provided with ra:

dial ribs, as shown in Fig. 7

Instead of the connecting-gearing an end less chain "may be employed to revolve the rollers. p 4 a The position in which the machine isoperated is that wherein-the axes of the rollers are horizontal but it may also be operated in any other position. Q It isobvious that the frames B B must be properly braced by the tie-rods T, as shown in Fig. 2, andadditionally strengthened by bands V, made of wrought-iron, and properly secured to said standards. Having thus fully described my invention, Iclaim V v 1.
