To securely hold this -particularly to. reels of the type used in conbearing cage assembly 6 in place on the drum junction with metal rolling mills for" handling shaft 3,an end plate8 having asufilcient diameter strip material, and especially to reelskof the to embrace theouterend of the bearing cage is 5 cantilever type. u I I fixedly secured to the end ofthe drum shaft by a Reels of this type have: a single supporting :.,plurality' of .stud bolts .9. fsurrounding the bearbearing for theirdriving end while theiroutboard ing cage, Bthere is provided a cylindrical housing endis customarily unsupportedxandkeptfree of cap against which the removable; -brajce 5 is 10 obstruction to permit acoil formed :on :the: reel directlycontacted when moved -to itsoperative 1o being readily removed.

I

bodiment ofv the invention therein illustrated is Referring now in detail to the removable .brace. shown as comprising areeLdrum I which may ,5it comprises a main brace arm sectionjaand" 40 be made in any suitablemanner, many forms of forearm-section 5b, the former being keyed for 40 which are well known inthe art. .For support- "pivotal movement to a verticaliy'disposed pivot ing this drum in theusual manner it is mounted shaft l6 which is secured in a supporting frame on a drum shaft} which is supported at one end i8. mounted onthe floor adjacent the reel or on' only in a fixed bearing stand 2 and connected to thehousing .of the miliand the latter connected a'suitable source of driving power notshown. to the former by anelbow joint 20. pivot 45 At the 'outboard end of this drum shaft there isshaft Ili is retained inca pair of end bearings l9 provided an anti-friction bearing" assembly 4; and 2! provided in its supporting frame l8 and which is adapted to receive the free end'of are-.1 the inner brace arm sectionia is keyed thereon movable horizontally'disposed deflection preventadjacent the upper of :these two bearings while ing brace 5. l a gear segment'23, which is utilized to swing the 50 As'illustrated more.particularlyin Fig. 4,this brace into and out'of its operative position, as outboard brace-engaging bearing assembly 4 is shown respectively infull and dotted linesin Fig. *madeupof aroller bearing cage assemblyfiwhich; v 1,]iskeyedto 'thepivot shaft i6 below the brace is mounted on a reduced portion 3a of the drum arm section 5a. Cooperating with such gear segshaft 3 with its inner end bearing against a ment to-move the brace is a gear rack '24. which is secured to a pair of plungers 25 and 26 respectively disposed for movement in a pair of cylinders 21 and 28 suitably located in the supporting frame l8.

To permit the assembly of the plungers 25 and 26 in the cylinders 21 and 28 the latter are provided with removable heads 29 and 3|, and for actuating the plungers a suitable source of fluid pressure not shown is provided and controlled in any well-known manner. 4

To meet the requirements demanded of the brace the brace arm sections 5a and 5b are made sufllciently strong to adequately brace the outer end of the drum shaft 3 and sufficiently long to allow the brace to be moved well out of the way of the largest contemplated coil to be wound upon the reel. for operation about a vertical pivot on the mill side of the reel to thereby most effectively resist the deflection of the drum shaft due to the tensional forces in the strip being woundupon the drum,

'I'he'reason for making the brace 5 in'two parts is to facilitate its movement into and out of operative position, and as will be appreciated, by breaking the brace slightly through the use of an elbow joint its length islessened whereby allowing it to be made with considerable bearing area'and at the same time permitting its being readily'moved from one position to another about its supporting shaft l5.

As'shown bestin Fig. 2,'the main brace arm section 5a of the brace which is attached to the pivot shaft I6 is made the larger -ofthe two and is designedto receive at its outer end the adjacent end of the forearm section 5b,the two parts being held together by an elbow joint employing a hinge pin 32 and limited in their relative breaking movement by shoulders 33 and 34 and 35 and 36, respectively, formed on the abutting ends of the two parts, the shoulders 33 and 34 being disposed to prevent the parts 5a and 5bbreak'ing at all in an outward direction and hence maintaining 'the'brace in a straight line when it in its operative position. The shoulders 35 and 35 on the other hand are inclined away from each other and on a sufiicient angle-to prevent the necessary breaking of thebrace to allowthe outer end thereof to freely clear the" bearing shell [2 when the brace is moved into and ing position. v

To normally maintain the brace'in its broken position so that'it can be readily returned from its inoperative to its operative position without main brace arm 5. The inner end of this plunger manual attention, a spring 31 and plunger 38 are provided in a bore 39 in theshoulder" 33 of the is disposed to bear against the face of the shoulder 34 of the forearm section member 5b and is enlarged to engage the inner end of the spring 31 which is maintained thereon and held thereagainst under tension by a screw cap 4| which 'is threadably engaged in the upper end of the bore 39.

To facilitate the engagement and disengagement of the brace with theshell at the end of the reel axis, a pivoted bearing block 44 is mounted in the free end of the arm section 5b. The

outer extremity of this block is cut out to engage a substantial portion of the periphery of the shell and the major part thereof disposed below the axis of. the reel to best support the weight of the reel and resist bending thereof due to the tensional forces of the strip. To hold the block in the arm section 5b the latter is bifurcated and a The brace is also, as shown, located out of operatwith said bearing cap.

pin 45 is extended through the extremities thereof and a hole provided in the center of the block, the hole being larger than the pin to permit the block to freely seat itself and move with respect to the shell when the brace is moved into and out of position. To further aid in the positioning of the block the ends of its outer extremity are rounded and its inner extremity, which is also rounded, seated against a correspondingly rounded surface which in the present embodiment comprises the outer face of a sheath 46 fitted between the inner end of the block and the inner end of the opening in the arm 5b. Through the use 'of this sheath the construction of the brace is facilitated and a design is provided which permits shims being inserted between the sheath and the brace to take up any play which may develop as the block or sheath wears away with use.

' and described what I now consider to represent its best embodiment. ,However, I desire to have it understood that, within the scope of the appended claims, the invention may be practiced otherwise than as specifically illustrated and described.
