APPARATUS FOR mAmPULA'rIoii or METAL-INGOTS AND THE LIKE.

This invention relates to appliances for the. automatic manipulation of metal ingots and the like at rolling mills, and refers to V improvements in or modifications of the in-- 'for a .patent in the United States of Amvention for 'which'I have made application I erica, Serial'No. 35668, filed 22nd June 1915.

5 sizes and classes of metal ingo ts, and enjablesthem, Where required to be turned .apparatus constructed according to,

myijaforesaid invention provides an 1 extremely efficient means for manipulating all automatically and in one operation through any required angle up to 180.

"The important. and characteristic constru'ctional features of my previous invent1on were the ingot contact members'one of which the so called receiving clutch con- 1 sisted of a serrated plate 01 plates pivoted 'to the up er portion of a counterbalanced which was ingturn' pivoted in connectionwith a cross head operated by a piston rod.. v

- The other ingot contact member consisted of'the so'called ingot turning clutch, or

operated '3' means of an arm, or lever, the said arm being pivoted in connection with a crosshead controlled by another piston rod, in such 'a way that it (the arm) could tilt. The upper end of said-arm was connected to the turning clutch by a il-inkf termed the forearm and the lower end of Y the tilting arm was connected through a linkjmil a series of mechanism with the said turning clutch.

My present invention, while embodying these, the characteristic features of my aforesaid principal invention relates to a simplified construction of apparatus designed for use where it is not required to deal with ingots or the like of so many different sections, or to turn them through so large a range of angles as was the case with the apparatus particularly described and shown in my former specification.

Specification of Letters l atent.

the county of Glamorganshire,

- Patented J an. 6, 1920.-

Application filed September 19, 1917. Serial No. 192,156.

The apparatus about to be described is particularly suitable for use in connection with cogging or roughing mills and isadapted to turn a bloom 'or ingot of simple section in one operation through an angle of asmuch as say about 90.

According to my present invention, in the case of the first described contact member, in place'of providing a serrated plate or plates pivoted to a counterbalanced framework which is in' turn pivoted in connection with its corresponding crosshead, I pivot one or several (preferably two) serrated plates or their equivalents to orin connection with the cross head.

As regards the other contact member, in

place of pivoting the turning clutch or impinging clutch to the end of a linkconnected to the lower extremity of the arm or lever through a series of mechanisms, I

piVOt the said link directly to the turning clutch. v.

In order that my present invention may be clearly understood I will now proceed to describe with reference. to the accompanying drawings, various forms of apparatus embodying my simplified construction.

Figure l 1s a side elevation partly in section of the improved apparatus in a position ready to turn an ingot.

Fig. 2 is a similar view with the parts in the position showing the ingot partly turned.

Fig. 3 shows the ingot fully turned.

Fig. 4 is asimilar view and in somewhat greater detail of-the left hand contact member.

Fig. 5 is asectional elevation looking in the directionof the arrow Fig.4. g

-Fig. 4 is a sectional side elevation of a modified form of the turningclutch, drawn to a larger'scale than Figs. 1-3.

Fig. 5 is a similar view showing another -m0dified form of the "same portion of the apparatus.

The same numera s and letters of refer enceare employed to denote the same parts in all the views. I v

Between-two of the conveying rollers R, in connection with the roughing or cogging mill, I provide transverse bedplates a acting as guideways.

Mounted so asto slide along theseguideways are the two opera ing members. One

ofthese consistsof a crosshea'd 7) operated by means of thep ston rod 6 and having plates 0 are enabled to dip downward but when the plates are released they return to their original positions.

The other sliding or operating member comprises a recessed'cross hea d (1, operatedby a piston rod d Pivoted within the rece'ssed portion of the cross head d is the tilting arm 6 the pivot being at f.

' Pivoted at g to the upper end of the tilting arm on lever e is a link it which is pivoted to the turning clutch p, the pivotbeing locatedina IBCBSS'S the wall of which also acts as stops for limiting the motion of the turning clutch p. Pivoted at. is to the lower end of the arm 6 is a link m, which inturn is pivoted to the lower end of the turning clutch p in asuitable recess.

shows a bloom oringot, in this case of square section, which it is desired to turn. 1" are screw stops for the purpose hereinafter described.

The use of this form of the apparatus will be easily understood.

The bloom q traveling on the rollers R is brought into position in the ordinary way between theclutching members of the turning mechanism. The parts are now ithe position shown, at Fig. 1 with the'side tresting on the plate C. On continuation of the pressure resulting from the movement imparted to said parts, including the-clutches, through the referred to turning mechanism the bloom Q is tilted up into position shown at Fig. 2, thesides 1, 2, 3 and 4 of the bloom then assuming the position indicated therein and on further continuing the pressure the side 4 of the bloom falls over on the top of the plate C the turning clutch p, rising into the position shown at Fig. 3.

On separating the cross heads I) and d, the counterbalanced plates 0 and. the parts of the turning clutch resume their original positions.

The screw. 1' screwing through the upper portion of the cross head 01 is Intended to come into contact with the-uppe'r-jend of the arm 6 in order to limit its movement. The screw r fulfils the same object at the other end of the arm 6.

As previously stated, the conformation'of the recesses in the part p limits the movement. of the said part.

Referring to Fig. 6 which as previously stated shows a modified form of the turning clutch, in this case both the link'h and the link m are carried to the same pivot 25 in the turningclutch p, the other detalls of con- J' st'ruction vremaining the same.

' Fig. 7-shows a further modification. It

of Fig. 6 when the links it and m are'pivoted tothe'same pivot at 25 no relative aimcross-head, a turning clutch provided with end of said clutch.

will be evident that from a consideration.

ing movement can take place'between'the. arm 0 and the links h and m,-but that they turn as a rigid whole upon the pivot f.

WVhat I claim and desire to secure by ters Patent of the United States of Amer ica is 1. In apparatus for manipulating'ingots in rolling mills, 'a turning member compris-i' ing a. cross head, means for operating said' cross head, a lever pivoted to the saidfcross" head, a clutching member, links connecting I said clutching member to each end of'th said lever substantially as described.

2. In apparatus for manipulating ingo in rolling mills, a'turning member comprise ing a cross-head, an arm pivoted in said" a recess in its upper portion, a link pivoted to said clutch within said recess and connected to the upper end of said am and a second link connected to the lower end ofsaid pivoted arm and to 3. In apparatus for mani plating ingots 'in rolling mills, a turning mnab'er comprising' a cross-head, an arm pivoted in said crosshead, a: turning clutch provided with a recess in its upper portion, a link pivoted to said clutch within said recess and connected to the upper end of said arm, a second link connected to the lower end of saidpiv oted arm and to the corresponding end of said clutch, a second cross-head, means for operating said second cross-head and serrated counter-balanced members pivoted to said second cross-head.
