To all whom it may concern.-

Be it known that I, WILLIAM WALLACE, a citizen of the United States, residing at Ansonia, in the county of New Haven and State of Connecticut,have invented a new and useful Improvement in Tools for Manipulating the Overfeed of Rolling-Mills, of which the following is a specification, reference being bad to the drawings accompanying and forming a part of the same.

In the manufacture of wire and wire rods, by rolling the same down from a billet or bar of metal, the wire is successively passed through a series of reducing rolls and by such passes is reduced in diameter and correspondingly increased in length. As the end of the wire issues from one set of rolls it is at once seized and entered between another set, and the loop thus formed extends laterally from the rolls to a greater or less distance, depending, of course, upon the difference of reduction between the two sets of rolls then acting upon it. In the case of wire or other like rolling mills this loop or overfeed comes to be of such length that it is likely, under the high speed of rolling to twist or become kinked or knotted as also to tangle with other loops running to and from adjacent rolls. Accordingly, it has been common to guide such loops by hand,to keep them running steadily in proper direction. In doing this, the loop is engaged by a hook in the hands of a workman, who retreats from the rolls as the loop issues, and properly guides it during its extension and prevents its end when freed from fiyin g aside. In thus managing and controlling the overfeed loops of wire or rods, the common form of workmans hook is an uncertain, and in particular respects, inefficient tool. The metal being soft and ductile, especially so when heated, there is danger that it become abraded or indented during its passage through the hook in the workmans hands, and so tend to engage or take hold upon the hook, in which event the hook may be pulled from the workman s hands and his function whollyfrustrated. Tangling or knottin g of the wire may present invention is to workmans loop hook,

so that it can be safely relied upon to permit the free passage of the wire through its jaw when the same is being reduced by rolling, as explained.

The invention consists in a hook of the kind described, which hook is provided with a friction wheel or roll so located in the jaw of the same that when the hook engages an over-feed loop the hook will bear wholly upon the roll, which by its revolution will permit the free passage of the loop through the hook without frictional obstruction, the loop passing around the roll as does a belt over a pulley, by peripheral travel therewith and not by sliding or dragging thereon.

In the drawings, the Figure 1 represents in side elevation a hook embodying my invention, Fig. 2 being a front'elevation of the same.

A is the handle of the hook, which is of any suitable length and size, being usually constructed of round iron or steel.

13 is the bend or jaw of the hook, which is of flattened or strap-like form, and is set at a slight angle to the handle, as shown in Fig. l.

C is the point of the hook, which is suitably reduced or brought to a rounded edge at its end, as by the curved bevelD inclining from the opening of the jaw of the hook outwardly.

E is the roll located in the jaw of the hook, the same being mounted to rotate freely on the pivot F, preferably passing through the handle and point parts of the book. This roll is grooved peripherally, and is of such size, the upper edge face of the roll is considerably below the end of the point. Thus, the loop can be picked up by the hook point, when the groove of the roll would not serve therefor, and the point will direct the loop to within the jaws of the hook and into the groove of the roll. Also this projection of the point above the roll, acts to prevent the loop leaving the jaws of the hook when, for any reason, it leaves the roll slightly. It is to be noted that the handle of the hook is at an angle to the jaws,or to the line passing paral lel to the parts of the jaw. This is for the purpose of giving clearance to the jaws; also by this form the jaws will be horizontally positioned, so as to readily engage a loop on the floor when the tool is held in the hands of a standing workman.

or the length of the point C is such, that In operation, the workman hooks the loop as it issuesfrom the reducing rolls, pulling it taut, or nearly so, and holding the hook firmly in hand retreats laterally from the reducing rolls. The loop passes freely through his hook, with slight resistance and without any manipulating the loops is thus rendered lighter, and is practically freed ofall danger to the workman, and there is no waste of product because of the inefficient hold of the Workmans hook upon the wire and consequent tangling or knotting, especially in thev case of manipulating wire of ductile and soft metal.

The construction of the loop hook, and the arrangement of the roll thereon may be'variously diiferent from that shown, but it is essential that the loop bear wholly on the roll i jaw. tendency to engage the same. The labor of when in the jaws of the hook, and it'is desir- 2o able that thepoint of'the hook'extend well beyond the roll and be shaped so as to readily engage the loop and direct it upon the roll as well as to prevent the loopleaving the hook 5 What is claimed as new is- A tool of the character herein described,

consisting of a handle inclined as described,

and having its lower end formed into a hook, leaving an open and unobstructed throat and .aroller mounted in thejaw of the hook below the pointC, of said hook, substantially as and for the purposes hereinbefore described.
