GUIDE FOR .ROLLING-MILL S.

To all whom it may concern:

Be it known that I, THEODORE-H. NYE, a citizen 'of the United States, residing at Vorcester, in the county of \Vorcester and Commonwealth of Massachusetts, have invented a new and useful.Improvement .in Guides for Rolling-Mills, of which the following is a Specification, accompanied by drawings forming a part of the same, in which v j Figure 1 represents a front elevation of a rolling mill housing provided with a guide embodying my invention. Fig. 2 is a sectional View of my improved guide on a larger scale, and shown on the plane of the broken line 2-2, Fig. 1. I

Similar reference letters. and figures refer to similar parts in the ditferent views.

The object-of my present invention is to provide an improved mode of attachment for rolling mill guides which will securev maximum rigidity and also facilitate their application to and removal from a rolling mill housing, and it consists in the construc-* tion and arrangement of parts as hereinafter described and pointed out in the annexed claims. 7

Referring to the accompanying

drawings

1, 1, denote the housings and 2, 2, a pair of rolls journaled therein. i

3 denotes the guide supported on a bar t attached to the front of the housings by bolts 5. f, and verticallyadjustable by means of slots 6, 6. The guide 3 may be used either with or without guide plates, a 'pair of which, in the present instance, are shown at 7 and8. The bar 4 extends across the housing and is provided on its upper side with the

longitudinal bearing surfaces

9 and 10 upon which the guide rests, and along which ,itis horizontallyadjustable to bring it in alincment with the circun'iferential grooves or passes 11' of the rolls. The guide 3 is provided-at its outer iid with a downwardly projecting apron 12, provided at its lowe1 end with a slot 13 for the receptionof a bolt-'14, having a head lo'horizontally-ad- .ju stable along a T shaped slot 16, having a central opening 17 on its upper side to allow the bolt 14; to be inserted in the slot. The upper surface of the guide bar tis also provided with an undercutor doveta led shoulder'18 to receive a corresponding'doves tailed shoulder 19 formed on the under side of the guidei When the guide is placed in position, with s the dove-tailedshoulders 18 and 19 engaging each other, as shown in Fig. 2, and with the bolt. 14 inserted, the nut 20 is tightened sufficiently to prevent the disengagement of the dovetailed shoulders 18 and 19, thereby holding the guide rigidly in position for use. By loosening the nut 20 slightly, the guide may be horizontally adjusted on the bar 4, or the slotted apron 12 may-be lifted off the bolt 14, and the guide removed.

In case the metal moving through the rolls becomes accidentally impeded,- forming what is known as a cobble, the strains upon the guide will become sufficient to lift it from its attachment to the bar 4, thereby preventing the destruction of the guide, or the bolt .14 may be made sutticiently weak to allow it to break under any unusual strain applied to the guide, the ()bJQCt bemg to allow the guide to'b'e (lisp-laced whenever a cobble ls formed, thereby preserving the guide and facilitating the removal of the cobble. The

guide is held by a single nut 20 on the front of the apron 121andin convenient position to be' reached by an attendant, rendering it an extremely easy matter to either attach or remove the guide or ad us t it as desired upon the bar 4. Any lifting strain exerted upon the guide will be positively resisted by the dovetailed shoulders 18 and 19, which are held in engagement bythe longitudinal strain resisted by the'bolt 14 and also by the frictional contact between the nut 20 and the apron 12. If-the frictionali resistance between the nut 20 and the apron 12, or the tensilestrength of the bolt 14 is less than the accidental lifting strain imparted to, the guide, the latterwill be raised from its seat.

On the right hand side-of the rails in Fig. 2 I have shown a guide :21 which used without any-guiding plates, but isjprovided with a method'of attachment to theguide bar 22, as already shown and described'with reference to the, guide 3, being provided with an apron 93, .having a slot 21' to receive a bolt 25, having a head 26 and a nut QT, by

which the. dovetailed shoulder 28 of the guide 1s held in engagement with a. corresponding dovetailed shoulder 29 on the 105 sageof metal therethrough .will produce 119 torque. By holding the end'of-th'e guide next the rolls by the interlocking dovetailed surfaces 18 and l9,"loc'ated in a vertical plane as far as practicable behind the ver tical plane of the attachment by the apron 12 and bolt ll, enables the guide to be held in place by a comparatively light apron and a small bolt.

I claim, l. A rolling mill housing having a guide supporting ,bar,. a guide mounted thereon,

said guide and said bar provided '-with reentrant engaging surfaces to hold said guide from vertical movement," and mean for holding saitl surfaces in engagement y a strain toward the rolls of the rolling mill.

2. A rolling mill housing having a guide supporting bar, a guide mounted thereon,

said guide and said bar provided with re-' entrant engaging surfacesto hold said guide from vertical movement, and a bolt para lel' with the longitudinal an'is of said guide for lioldingsaid surfaces in engagement.

3. A rolling mill housing having aguide" supporting ,bar, a guide mounted thereon, said guide and said bar provided with 're-'; entrant' engaging surfaces for holding said gui'de from vertical movement,but arranged to allow horizontal movement away from the rolls of the rolling mill, said bar having a slot parallel with said surfaces, said guide havin a detiendin flan e outside of said guide and said bar near the-end of,said guide next said rolls, with the surface on said guideoutside of th surface on said bar, and means parallel with the longitudinal axisxof said guide at or near the opposite end of the guide for holdingsaid surfaces in engagement by" a strain towatrd said rolls.

a A rolling mill housing having a guide supporting bar, a guide mounted thereon, said guide and saidbar'provided with "reentrant engaginjg surfaces arranged to hold said guide from "vertical. movement, but to allow horizontal movement of said guide in a direction away from the rolls of the rolling mill, and means for holding said surfaces in engagement.

. 6. A rolhng mill housing having a guide supporting bar, 'a' guide mounted thereon,

said supporting bar and said guide provided with reentran t engaging surfaces, whereby the inner end of said guide is held from vertical movement,.and means attached to said-bar, f r fiictionally holding the outer endof said guide from vertical movement.

7; Aro'lling-inill housing having a guide supporting bar, a guide mounted -'thereon, said supporting bar and said guide provided with reentrant engaging surfaces,whereby the inner end of said guide is held from vertical movement, and a bolt held in said bar and'in frictional contact with said guide, ar-

ranged to draw said surfaces 'into' engage mentand to hold the outer en'd of said guide from vertical movement.
