APPARATUS FOR THE AUTOMATIC MANIPULATION 0F METAL INGOTS AT ROLLING- MILLS.

Specification of Letters Patent.

Patented Oct. 25, 1921.

Application filed July 7, 1919. Serial No. 309,131.

T 0 all whom it may concern:

Be it known that I, EVAN WALTER DAVIES, a subject of the King of Great Britain and Ireland, residin at Dowlais, in the county of Glamorgansliire, Wales, have invented certain new and useful Improvements in Aparatus for the Automatic Manipulation of l etal Ingots at Rolling-Mills, of which the a specification.

This invention relates to appliances for the automatic manipulation of metal ingots and the like at rolling mills and refers to improvemnts in or modifications of apparatus of the type for which Letters Patent have been granted to me Nos. 15117, dated 24th June, 1914, and 113225, dated 13th July, 1917, in Great Britain.

With apparatus of the type in question, as hitherto constructed, where it has been desired to turn ingots of manydifferent 'sizes and shapes, through a large range of angles, the mechanism has been complicated, and costly, and the object of my present invention is to provide a comparatively simple apparatus which is adapted to turn ingots and the like varying, greatly in size and shape through a large range of angles.

According to my present invention, I so construct and/or mount the turning or receiving members that they are adapted to give the ingot or bloom two successive turning movements, and to eifect this I construct the turning or operating member so that it moves about two independent pivots or their equivalents in succession, while nevertheless the said turning member may be of extremely simple construction, consisting preferably of one or two parts only.

As regards the receiving member, that is, the member for holding the ingot or the like while the operating member is giving it the turn, I may construct this from two counterbalanced plates, one of which holds the ingot during the first portion of the turning movewhich is somewhat behind the first mentionedplate, holds the ingot or the like While it is being turned through a further amount of arc.

, Asian alternative, I mayprovide a coun terbalanced receiving plate or. plates, so shaped that the ingot to be turned first comes into contact with an advanced or projecting portion thereof, after which it comes into contactlvvith another portion of the said plate, which gives it a second turning move- One of ment. For enabling a large range of sizes to be dealt with I prefer to mount the turning and receiving members so that the pivots are adapted to slide in slots, the result being that operating and receiving members can automaticall ad'ust themselves for dealim y l r member for holding the ingot. during the process of turning, constructed according to the present invention, the turning member itself or operating member being of the type illustrated in the drawing accompanying my British specification No. 113225.

Fig. 2 is a detailed side view of a modified form of the ingot-receiving member.

Figs. 8, 4 and 5 are vertical longitudinal sectional views showing another modification of the invention, with the ingot or bloom at different stages of the turning operation.

Figs. 6 and 7 are also vertical sectional views of still further modifications relating more particularly to the clutch turning member.

Fig. 8 is a detailed side view of a still further modification relating more especially to the ingot or bloom receiving member.

Fig. 9 is a partially side and sectional view of a still further modification of the invention. a V

' Figs. 10 and 11 are side elevations of still further modification relating more particularly to the bloom receiving member.

a indicates the level of the conveying rollers, b is the cross. head for the receiving member, and c is the casing of the cross head of the operating member. These (Toss heads are controlled in the ordinary manner by piston rods;

03 and (Z are two counterbalanced plates,

one mounted on each side of the cross head.

these plates al projects considerably in front of the other as shown, and the forward portions are preferably serrated.

The turning member 0 comprises a pivoted plate etowhich again is pivoted the actual contact or operating member t.

The apparatus is shown operating an ingot or bloom g, which is square in cross section.

The operation will be readily understood. Supposing the ingot g to be resting on the conveying rollers a, the forward portion of the counterbalanced plate d is brought against the same and the contact member gives the ingot a preliminary turn, the result being that it falls over and depresses the forward end of the plate (Z upon which it rests, the action being similar to that illustrated in Figs. 8, 9 and 10 in the drawing of my British Patent 113225.

The cross head 0 is then drawn back and the operating member f again picks up the ingot g pushing it against the second plate (Z which holds it for the second part of the motion; this is shown in Fig. 1.

The particular construction illustrated is one in which the forward portion of the cross head 6 is so shaped that the angle of the ingot comes against it after the said ingot has been turned through a second angular distance amounting to only elf degrees. If the front of the cross head 7) were cut away or the plate d projected to a greater extent, the ingot 9 would be turned through a second angular distance of 90.

In many cases however it is necessaryto introduce the ingot at a particular angle for the further rolling operations, and the case illustrated isv the one where it is desired to introduce a square ingot held up upon its angular point after it reaches a total turning movement of 135.

Referring to Fig. 2 this illustrates a modification in which in. place of providing two separate counterbalanced plates (Z1 and on each side of the cross head, a counterbalanced plate (Z is provided on each side of the cross head Z). Each of these plates (Z is provided with adownwardly projecting serrated portion (Z into contact with which the ingot g is first brought and with a second serrated portion (1 into contact with which the ingot g is brought for the second stage of the turning. y

In the modification as embraced in Figs. 3, l, and 5 the device is adapted for giving a larger range of turning movement for the ingot or bloom, the receiving or holding member being of the ordinary counterbalanced type. Y

72 is a plate which in this case forms the turning clutch-member, which is pivotally supported in position upon pivots 7c and q in working provided in the casing'of the head.

By means of this construction, with the parts in the position as shown at Fig. 3 when the turning clutch member is pressed against the ingot g, a preliminary turning .moyement takes place about the pivot m. This contmues until the pivot lc has traveled to the end of the slot p as shown at Fig. 4:,

after which the clutch member pivots at /a, the ivot on traveling along the slot '9 until it reac ies the end thereof, as shown at Fig. 5 so that a large turning movement is effected with a very simple operating or turning clutch, in this case, consisting of a single member 01.

lVhere a greater range of movementis required, the turning member may be made in two parts, as for instance as disclosed, in Fig. 6, wherein a plate It is provided mounted as previously explained with respect to Figs. 35 and which plate has mounted thereon the turning clutch proper 7-.

lnsome cases in place of providing two separate pivots la and m'I may provide an arcuate projection S, at each side of the plate It. This arrangement is illustrated in Fig. 7 wherein Z refers to an arcuate recess or slot formed in the-side of the casing of the cross head 0, adapted to receive said projections.

By means of this construction the end S of said projection first travels along to If, the end S acting as the pivot, after which the plate It turns about the end S of said projections as a pivot, and the end S travels along the bottom of the slot or recess until it reaches the end 15 of the recess.

In the modification as disclosed by Figs. 8 and 9 is shown a construction which I may adopt in order to enable the receiving or holding and operating members to deal with ingots varying considerably in cross section and especially suitable in addition for presenting the ingot after the required amount of lturning at some particular angle to the rol In this instance the receiving members carried by the cross head I) are constituted of plates (Z provided with forwardly projecting serrated portions cl and of another serrated portion (P located behind the first mentioned portion 6 V The side plates (Z are also provided with upwardly and forwardly projecting portions (Z d? as a distance bar or piece connecting the side plates d (Z and d are proj ecting rods, on each side of the head. The

lower rod (i works in a vertical slot 6 while the upper rod d works'in an angular slot 6 in the sideplate. r

Referring to. the construction just .described we will suppose that it is required to turn a small bloom square in cross section through 135 and presentit on end to the rolls. At the commencement of operations, the rod d, which constitutes the turning pivot for .the plate d is at the top'of the slot 6 and for the first turn effected by the forwardend al theparts remain in this position. After this turn has been effected as the turning member pushes on the bloom, the upper edge thereof comes against the top wall of the recess a and the plates 03 are raised and then the lower forward edge of the bloom comes against the serrated portion (5 of the plates (Z while at the same time the plates (Z slide upward owing to the provision of the slots 6 and b the parts coming into the position shown in Fig. 9.

It will be evident that a considerable range of sizes may thus be manipulated.

he operating member carried by the cross head 0 is mounted in a similar way, the plate it in the present case being provided with a pivot-pin a riding up slots 0 in the casing 0.

It will be evident that the shape of the inner portion of the receiving or holding member must be modified according to the form in the ingot to be turned and held upright.

For instance if the ingot g were of oval form and it were applied to present the ingot to the rolls with the major axis of the ingot in a vertical position, the receiving plates in place of being shaped as shown at Fig. 9 would be of semi-elliptical shape as at (i In the modifications as disclosed by Figs. l0 and 11 are shown two forms of plates for receiving various sections and giving them a turn in two stages, the serrated portion al first coming into action as previously explained, after which the part al comes into action to give a second amount of turn or to hold the ingot in some desired position in order to present it as required to the rolls. Where necessary the plates are so mounted with respect to the forward portion of the cross head 6 that such portion cooperates.

with the counterbalanced plate or plates to hold the ingot in the required position.
