Application filed January 30, 1923. Serial No. 6158Zi2 To all whom it may concern:

Be it known that l, Gnono-n \V. \Vnninn, a citizen of the United States, residing at Girard, in the county of Trumbu lland- State of ()hio, have invented certain; new and useful Improvements in Repeater 'lerminals for tolli Mills; and l do-de'elar' the following to be a full, clear, and exact description of the invention, such as willenable others through the repeater, the work becomes twisted to someextent, making it extremely diiiicult for the attendant to properly ide this work to the rollers. t is the ob ect of my invention however to provide asimple and inexpensive, yet an e liiciei'i't and reliable terminal for the repeater or work returning guide, which will not only guide such work to the next set of rolls, but will straighten the work if it has been twisted while making the return bend from one set of rolls to the next. In carrying out this object, a further aim is to provide aterminal which will belaterally expansible tosome extent to permit itto accommodate work of different sizes and to 'enable the work to be easily removed in case it should by any possibility become jammed.

lVith the foregoing in view, the invention resides in thenovel subjectmatter hereinafter described and claimed, the description being supplemented by the accompanying drawings.

Figure l is a plan view showing the application of the terminal to a rolling mill.

Figure 2 is a side elevation of the terminal.

Figure 3 is a central vertical longitudinal sectional view.

Figure 4 is a horizontal sectional view on line 4 -4 of Fig. 2.

Figure 5 is a vertical transverse sectional View through the terminal, adjacent the work receiving end thereof.

Figure '6 is a view similar to Fig; $5,011 line 66 of- Fi'g. 4. 4

In the drawings above briefly described, the characters R and R" designate the first and second sets of rolls of a rolling-"mill for forming strips andbars; and-the letten G refers to the usual J-shaped repeater or guide which returns the workiafterit leaves therolls it, in order'thatitmay be guided into the. rolls it. Between the outlet end of the guide G- and the inlet guide 6; of the mums, the ii'np'roved terminalT is located, this terminal being internally shaped toreeeive the work from the guide G andstraighten it if it h'as becometwisted and then direct it into the guide G.

in the preferred form of construction, the terminal T is of the formation disclosed in Figs. 2 to 6. The numeral 1 designates a horizontally elongated base plate which is suit-ably connectedat 2 with the outlet end of the guide G, a pivot being preferably provided at the point 2 inord'er that the outlet end ofthe terminal" may beproperly alin'ed with the guide G under all circumstances. The rear end of the plate 1 is formed with a'throa't 3 which guides the work between a pair of elongated gui'dingand straightening members which arejmounted on the plate 1 and have their inner adjacent sides longitudinally grooved throughout their lengths, as indicateda't 5, to form-"aguiding and straiglitening passage for the work. decreases in cross sectional area from its inlet to its outlet end and is helically directed to some ei'it'ent' as will be seen' by comparing Figs. 5 and '6. Thus, if the work has been twisted to'som'e extent wliilewpassing aroundth'e guide G, itwill gradually be straightened as it 1 passes- 'through the 'coacting grooves; 5.

I mount the members 4 in such a manner that they may be moved outwardly away from each other to some extent, in order to accommodate them for the handling of larger work and in order that the work may be removed from the terminal, in case it should by any accident, become jammed. In the preferred form of construction, the members 4 have lateral ears 6 pivoted at 7 to similar ears 8 on the rear end portions of the bed plate 1, so that the front ends of said members 4 may be swung outwarly as required. I prefer to provide these members 4 with outstanding ears 9 near their This passage front ends which contact with the upper sides of slotted ears 10 on the bed plate 1, clamping bolts 11 being passed through the two sets of ears in order that the members 4 may be held rigidly after adjustment.

By the use of my invention, difficulties heretofore encountered are overcome in an expeditious manner and a device is provided which will be efficient and reliable and will greatl save in labor and time.

As excellent results may be obtained from the details disclosed, they may be followed if desired. However, within the scope of the invention as claimed, numerous minor changes may be made.

I claim:

1. A terminal for the work returning guide of a strip rolling mill, comprising an elongated laterally expansible work receiving and straightening guide, closed at its sides and open at its ends, the interior of said guide decreasing in cross sectional area from its inlet to its outlet end and being helically formed to straighten the strip if twisted in the work returning guide.

2. A terminal for the work returning guide of a strip rolling mill, comprising a base plate having means for mounting it in operative relation with the return guide, a pair of elongated work guiding and straightening members on said base plate having their inner sides longitudinally grooved throughout their length to form a guiding and straightening passage for the work, said passage decreasing in cross sectional size from its inlet to its outlet end and being helically formed to straighten the stripif twisted in the work returning guide, and means for mounting said members on said base and permitting lateral adjustment thereof.

3. A terminal for the work returning guide of a strip rolling mill comprising a base plate having means for mounting it in operative relation with the return guide, a pair of elongated work guiding and straightening members on said base plate having their inner sides longitudinally grooved throughout their length to form a guiding and straightening passage for the work, said passage decreasing in cross sectional size from its inlet to its outlet end and being helically formed to straighten the work, means pivotally mounting the rear ends of said members on said base plate, and means for adjustably securing the front ends of said members to said plate and for permitting lateral adjustment of said members.

4. In combination with a work returning guide of a strip rolling mill, a terminal comprising a base plate mounted in operative relation with the return guide, a pair of elongated work-guiding members on said base plate having their inner sides longitudinally grooved throughout their lengths to form a guiding passage for the work, means pivotally mounting the rear ends of said members on said base plate, and means for adjustably securing the front ends of said members to said plate and for permit ting lateral adjustment of said members.

5. The combination with a pair of rolling mills having reducing passes therein, of a horizontally disposed open trough return bend guide adapted to receive a strip from the passes of one mill and to reverse its direction towards the passes of the other mill and having a covered delivery end, a base plate pivoted to the end of the guide provided with a covered receiving end matching the delivery end of the trough, and a twisting guide for the strip mounted on the pivoted base for delivery to the receiving passes of the mill.

6. The combination with a pair of rolling mills having reducing passes therein, of a horizontally disposed open trough return bend guide adapted to receive a strip from the passes of one mill and to reverse its direction towards the passes of the other mill and having a covered delivery end, a base plate pivoted to the end of the guide provided with a covered receiving end matching the delivery end of the trough, and a twisting guide for the strip composed of two co-acting sides adjustably mounted on the pivoted base and providing a guiding channel for the strip.

In testimony whereof I have hereunto afiixed my signature.

GEORGE W. WVEIMER,
