TRANSFER MECHANISM.

SPECIFIGATIOIT formingpart of Letters Patent No. 661,823, dated November 13, 1900. Application filed llugust Z, 1960 Serial No. 25.635. (No model-l 1 0 aZZ whom it may concern/i Be it known that I, EDWIN E. SLICK, of

My invention relates to the transfer mechanism employed in rolling-mills for carrying a piece of metal laterally from one pass to] another in the same or another set of rolls,

finger.

level than the first pass.

Heretofore the arms used for the purpose have been provided with rigid fingers on each side which hold the metal in. place and prevent its accidental displacement, and with this type of arms it was necessary to have the path of the arm clear when moving it into position to receive the piece. .The mill could not therefore be fed uniformly and regularly,

as is desirable, but the metal must'be held; back from the transfer-pass until the trans fer-arms were in position to receive the metal as itemerged from the rolls. A

My invention overcomes this difficulty and allows the mill to be fed regularly, as desired, and independently of the position of the transfer-arms; and it consists in providing upon one side of the transfer-arm a movable finger or detent which will be moved aside as the arm is swung out to receive the piece and will automatically resume its normal'position as soon as it passes the.piece to hold the metal in place during transfer. i In the drawings, 2 represents one of a set of feed-rolls extending from the roll-pass, in

this case the last upper pass of a three-high mill, 3 being one of the rollers leading to a lower pass, and 4 one of the vertically-movable rollers employed to transfer the metal from the lower to the upper passes of this mill.

5 is one of the, rollers on a feed-table leading to the pass of another mill at a lower level. I have shown these rollers as mounted on shafts 6, carrying pinions engaging toothed wheels 8 on the extended shafts of rollers 2. Between the two feed-tables is mounted a extending transfer-arms 10 and having a lever-arm 11, connected by links 12 to the plungers of single-acting cylinders 13. The arms 10 are provided with upper supports or rests 14, having at one side a rigid fingerl5 and at the other a hinged detent 16, provided with a counterweight 17, which normally holds the .detent in vertical position, as shown in full In operating the arms the lines in Fig. 1. shaft 9 is rocked by admitting fluid to one of the cylinders to swing the arms into the position shown in Fig. 1. Ifthere is no metal onthe rollers 2 during this movement, the

Ldetent has no action beyond that of any rigid If the metal is lying on the rollers,

however, the detent engages the metal, as

shown in Fig. 2, and as this part of the rest passes the metal in the last portion of the swing the detent is released and the counterweight immediately returns it to normal 'po-' sition. sition shown in dotted lines and deposit the metalon the rollers 3, by which it is carried forward to the next ,pass.

The ad vantages of my invention result from the use of the movable detent, since this enables the transfer-arms to operate whether themetal is in the path of the arms or not, thus allowing the metal to be fed independently ofv the positionof'the arms. The arms may be used to transfer metal" to another pass in the same mill or to a'pass of another mill, and only part of its arms may be provided with thedetents, the others being open on the detent side, and manyother changes The arms are then swung to the polongitudinal rock-shaft 9, carrying upwardlymay be made within the scope of my invention. i i
