REPEATING MEOHANISM FOR ROLLING-MILLS.

Application filed .T une 29, 1915.

To all whom t may concern:

Be it known that I, WILLIAM F. CONKLIN, a citizen of the United States, residing at Tarentum, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Repeating Mechanism for Rolling-Mills, of which the following is a specification.

My invention relates to rolling mills for plate or sheet metal.

It has for its object to provide a repeater which may be easily mounted on the ordinary housing of a two high mill for returning the sheets in front of the rolls, for rerolling, or so adjusted out of operative position, as to permit the sheets to pass directly through in the ordinary way.

The invention comprises an arc-shaped guide frame having bearing rollers, pivotally mounted upon a supporting hanger frame for adjustable location with relation to the rolls and provided with an adjusting operating lever, as shall be more fully hereinafter described. j

Preferred forms of the invention are shown in the accompanying drawings, in which- Figure 1 is a partial plan view illustrating one of the supporting hangers and the operating lever. Fig. 2 is a sectional elevation showing the device mounted between the housings in operative relation to the rolls. Fig. 3 is a view similar to Fig. 2 illustrating a construction utilizing an inner series of additional guide rollers. Fig. 4 is a view of the adjustable guiding mechanism and its parts, detached. Fig. 5 is an enlarged cross section, on the lineV. V. of Fig. 2. Fig.l 6 is a similar section on the line VI. VI. of Fig. 3. Y

In the drawings, 2, 2, are the rolls mounted in the usual way between the ordinary housings 3 of the mill, and having transverse tie rods or

braces

4, 4.

Ordinarily, the plates or sheets are passed through between the rolls 2 on the line @,a, from front to back, and are received on a table or other support beyond the roll train, from which they are ordinarily returned to the front of the rolls for re-rolling, by hand. For the purpose of automatically returning the plates or sheets, after passing through `the rolls, I provide an arc-shaped frame composed of two

curved side plates

5, 5, connected by suitable bolts 6 with mterven- Specification of Letters Patent.

ling braces, and having series of staggered housings. The hanger 11 bears by its ends on said rods, and is provided with caps 12 and securing bolts 13, by which secure attachment may be made, with ample provision for adjustment to variations in the rods 4, or for adjustment thereon with relation to the rolls. Hangers 10, there being one at each side for each pair of

plates

5, 5, are provided with

suspending eyes

14, 14, for attachment to a crane or the like.

For the purpose of providing pivotal adjustment for the arc-

shaped frame

5, 5,) its supporting extensions 9 are pivotally hung upon stud extensions 15 having terminal bolt ends 16 (squared or slotted for a wrench or screw driver), and extending eccentrically of a cylindrical barrel 17 mounted in bearing 10. A set screw 18 fixedly4 holds said barrel in position, so that it may be turned to the desired degree and there held. By this means the arc-shaped guide roller frames may be accurately adjusted with relation to the rolls.

Beyond the pivotal mounting of the roller carrying frames, they are provided with extensions or lugs 19, secured in any suitable manner and adapted to receive and support at"g one or both end portions of the entire tilting structure, 4an actuating rod or bar 20. kSaid bar extends across the ends of all of the plates 5, is preferably squared or splined, and is ixedly secured in the several lugs 19, so that whenfpower is imparted to the bar, it will rock the entire frame upwardly or downwardly as to the series of rollers 7 on the pivoting supports 15. For the purpose of thus actuating the frame, bar 20 is provided at one end with an operating lever 217 Awhich has a limited range of lateral moveviding a handle by its terminal, and is operable verticallyv along the inner face of a guiding and limiting frame member 24, which may conveniently be of angle form, bolted to the inner edge of the housing, as clearly shown.

Extending inwardly of frame 24 are limiting pins or

abutments

25, 25, at the upper end and 26 at the lower end. By this means the entire frame may be tilted upwardly out of the range of the blank, as indicated in dotted lines in Fig. 2, and there held by pin 26, or may be lowered to operative position, and lever 21 ixedly held between the adjacent studs 25.

For the purpose of insuring engagement with the studs or

pins

25, 26, after the rais-- ing or lowering operation, and of positively thrusting the lever toward the inner face of frame 24, I provide a spring 27 surrounding bar 20, bearing by its inner end against a collar 28 on the shaft, and by its outer end against a sliding collar 29. Said collar 29, being non-rotatably mounted on bar 20, as by a squared or splined opening, is chamfered oil at its inner portion, providing clearance 30, whereby its outer portion will always bear with a defined leverage against the hub of lever 21, whereby to thrust it outwardly toward the face of frame 24, thus insuring engagement with the pin or pins.

The lower ends of

roller carrying frames

5, 5, are provided with terminal blocks 31, adapted to provide an initial bearing surface for the edge of the plate and to deflect it upwardly around the upper roll and against the series o1' rolls 7. Said bearing terminal 31 is adjustably mounted between the side plates 5 by means of bolts 32 having slotted engagement with the plates, whereby to compensate for wear and relocate the block, as desired.

'The construction and operation of the mechanism as illustrated in Figs. 1 and 2 will be readily understood and appreciated from the foregoing description.

In Figs. 3 and 4, the same general arrangement of parts is shown, and identified by corresponding numerals having the exponent a. These figures also show the use of a series of supplemental inner guide rollers 33, so arranged with relation to the rollers 7 a as to provide between them an arc-shaped path for the passage of the blank. This arrangement is desirable at times in the case of rolling very thin sheets, or where there isliability to buckle or unduly curve toward the upper roll 2a, and whereby to positively provide a limiting open pathway for the blank, in returning it vto the front of the4 rolls. In such case rollers 33 are mounted on carrying studs 34 mounted in an arcshaped frame 35 connected with the main frames 5, by arms 36 extending outwardly and backwardly and secured by the cross shafts 6a of the general framework construction, as clearly shown in Fig. 6. By this means the inner series of rollers 33 are fixedly held with relation to the outer rollers 7, and the entire structure may be actuated in the manner already described. I preferably provide, at the end of'frames 35, terminal bearing blocks 37, which may engage against the face Of the upper roll, whereby to positively deflect the blank into the arc-shaped guiding passageway. The construction and operation otherwise is `substantially the same as in the simpler form above described, and capable of the same range of movement and adjustment.

The advantages of the invention reside in its Vfacility for returning' light plates or sheets of metal automatically for 1re-rolling. The construction is such as to adapt it to mounting between the housings of an ordinary roll train, without any specially designed supporting mechanism, and enabling the easy 'application and removal of the device, and its utilization Vwith various standard constructions of mill practice,due to its construction and manner of mounting. This is of especial advantage in connection with the usual and necessarily frequent land rapid change of rolls of the mill, the entire structure being readily lifted away, merely by removal of the caps 12 and adjustment of lever or levers 21, utilizing a crane and the,

supporting eyes 14.

The accurate and rapid adjustment provided for by the eccentric mounting of the pivoted roller frames enablesthe operator to adjust the mechanism to the diferent conditions of use. The spring actuated operating lever insures positive holding ofV the frame in raised or lowered position and against accidental displacement. Y

The advantages of the invention will be readily appreciated by all those familiar with the rolling of sheet metal; it may be changed'or varied in construction or adaptation to various conditions of luse by the skilled mechanic; and I do not desire to be limited to the specific construction and arrangement shown, except as required by the appended claims.
