To all whom/it mag/concern.-

Be it known thatLVIcToRE. EDWARDS, a citizenof the'United States, residing at Worcester, in the county of W'orcester and Commonwealth of Massachusetts, have invented a new and useful Improvement in Guides for Rolling-lvlills, of which the following is a specification, reference being had to the accompanying drawings, forming a part of the same, in which- Figure 1 represents aside view of a rollinglnill housing with a pair of rolls held therein and havinga bar-guide embodying my invention. Fig.2 is a side view of thesamewith one side of the housing removed and the rolls shown in sectional view on line 2 2, Fig. 3. Fig. 3 is a top' View of my improved guide, showing the lower roll and a portionof the housing in sectional View. Fig. 4 is a transverse vertical sectional view of the guide on the plane of the adjusting-screw. Fig. 5 is a central longitudinal sectional view of the adv justing-screw with a portion of the wrench for rotating the screw andinserted therein. Fig. 6 is a side'view of the adjusting-screw with the wrench shown in section on line 6 6,.

Fig. 5.

Similar reference-figures refer. to similar parts in the different views.

My present invention relates to a guide ide-i signed for supporting the bar fed to a rollingmill in proper position to presentthe rod" to the circumferential grooves orpasses of the rolls; and it consists in the constructionand arrangement Ofparts as set forth in the m,

nexed claims.

Referring to the drawings, 1 denotes a rollhousing containing in the presentinstancea single pair of rolls consisting of an upper roll' The upperand lower 2 and a lower roll 3. rolls are provided with the usual circumferential grooves or passes, that in the lower roll being shown at 4, Fig. 3. In front of the rolls is a bar-guide 5, embodying my invention and consisting of a supporting-frame 6, attached to the housing and provided witha rectangu lar opening 7, Fig. 4, extending therethrough and forming a chamber for the guide- plates 8 and 9. The inner sides of the guide- plates 8 and 9 are recessed at 10 to fit the sides of the bar 11, which in' the present, instance'is C elliptical in its cross-section, and its contact withthe sides of theguide- plates 8 and 9 holds it from rotating about its axis asit is presented to the rolls. On one side of the frame 6is a screw-threaded opening 12, whose di- 1 j ameter is substantially equal to the width of the-adjacent guide-plate 9 'for the purpose of receiving an adjustingscrew 13,; having a broad inner face 14 hearing against the outer' side. of the guide-plate 9, and substantiallyequal in width to the width of the guide plate.

. The opposite side'ofvth'e adj u'stifngrscrew 13" I diametrically opposite a space between the:

teeth. The adj u'stingescrew 13 is rotated in the frame 6 by means of ascrew-rotating device 17, consisting of a rectangular bar 18, provided with ahead 19, having onfldiainetrically opposite corners the'projecting teeth 20,

adapted to engage 3 the spaces between the teeth 16 of the adjusting-screw, as shown in Fig.6, with'the'planeof theteeth 20 at one side of the center of the adjusting-screw,

thereby allowing the teeth 20 to be shifted into diiferent spaces 21. s

.The multiplicity of teeth 16 in the screw allows the teeth 20to be shifted into different'spaces 21 in order to adjust the bar 18 relatively tothe screw, so the operative leverhandle 24 may stand in the proper position and ata convenient angle when the bar 11 is embraced-between the guide-plates. The rectangular bar 18 is rotated by a wrench com prising a block 22, having a rectangular hole filling the ,bar 18 and provided with a setscrew 23', which is extended to form a lever handle 24; The head 19 is;loosely.inserted in therecess of the adjusting-screw,- with its teeth 20 engaging twoofthe spaces 21 between the teeth-16. The bar 18 passes through and is free to turn in an opening in a bracket 25, attached to the housing, and endwise withdrawal of the bar 18 from the recess in the adjusting-screw is prevented by a stud 26 in the bracket overlapping the block 22. By raising the lever-handle 24 in the position shown in Fig. 1 the adjustin g-screw 13 is unscrewed to allow the guideplates 8 and 9 to separate far enough to permit the easy entrance of the bar 11. The leverhandle is then depressed and the adjustingscrew 13 turned against the guide-plate 9 to bring the recessed faces of the guide-plate into close contact with the sides of the bar, thereby holding the bar firmly against rota tion about its axis and at the same time allowing it to move logitudinally between the guideplates 8 and 9 as the bar passes between the rolls. The guide-plate 9 fits loosely in the rectangular opening of the frame 6 in order to allow its recessed side to adapt itself to the side of the bar, and the guide-plate 9 is prevented from rocking by making the face of the adjusting-screw 13 substantially equal to the width of the guide-plate, and preferably wider than the greatest diameter of the recessed face, so the advance movement of the adjustingscrew will move the guide plate 9 bodily against the bar 11. and afford a firm support behind the plate and throughout its entire width. By my construction the screw 13 is a plain-faced jaw cooperating with the plate 8 in holding the rod, the plate 9 simply serving to provide a recessed face fitting the side of the bar. The plates 8 and 9 are removable, allowing others to be substituted, and adapted to bars of diiferent shapes in cross-section. A slight movement of the lever 24 serves to release and tighten the bar between the plates 8 and 9.

Vhat I claim as my invention, and desire to secure by Letters Patent, is

1. A guide for rolling-mills, consisting of a frame provided with a chamber for guideplates, a pair of recessed guide-plates substantially filling said chamber in one direction, and adjustable in the opposite direction, a screw-threaded opening in the wall of said chamber and communicating therewith and having its diameter substantially equal to the diameter of said chamber, and a screw held in said opening with its end bearing against one of said guide-plates, substantially as described.

2. The combination of a pairof guide-plates having recessed faces to engage the bar, a frame for supporting said plates, an adj ustingscrew held in said frame and having one end bearing against one of said guide-plates with the diameter of said adjusting-screw greater than the width of the recessed face of the guide-plate, and a toothed recess in the op posite end of said screw to receive a removable wrench-bar, substantially as described.

In a guide for rolling-mills, the combination of a guide-plate having a recess adapted to engage one side of a bar, a frame for holding said guide, an adj listing-screw held in said frame and having one end bearing against said guide-plate, the diameter of said screw being greater than the recess in said guideplate, and a toothed recess in the opposite end of said screw to receive a serewqrotating device, substantially as described.

4. The combination with a guide-plate-holding frame and a pair of recessed guide-plates held in said frame, of an adjusting-screw held in said frame and having one end bearing against one of said guide-plates,.witl1 the diameter of said screw greater than the recess in said guide-plate, and a toothed recess in the opposite end of said screw to receive a screw-rotating device, said recess containing an unequal number of teeth, substantially as described.

Dated this 5th day of February, 1901.
