ll Claim. ((Cl. 2i2t8) This invention relates to reels or coil centers of face of the body 6, in which a jaw t is fitted. the type now commonly used to carry coils of This jaw has a number of cam surfaces 6 on metal strip which is to be cold rolled by means of one of its sides which are engaged by cam sura l-high mill, one of the objects being to provide faces l on the side of a laterally shiftable jaw l 5 a reel of this character which may be easily hanwhich is also fitted into the groove. When this dled and mounted. Another object is to provide bar is longitudinally moved the jaw will be moved an improved means for securing the ends of metal clrcumferentially of the body so as to eifectively strip to such reels. Other objects may be inclamp the end of a strip between itself and the ierred. side of the groove.

An example of a reel embodying the features of The groove 5 may be slightly inwardly flared 10 the invention is illustrated by the accompanying and the sides of the elements 6 and l which condrawing, Figure 1 being a side elevation showing tact the sides of this slot may be beveled, all as is the improved securing means, with the bearings shown by Figure 2, whereby the parts may be for the reel shown in section, and Figure 2 being retained in the groove by circular rings 9 which a cross-section from the line IIII in Figure l. encircle the extreme ends of the body i and serve 15 More specifically, this reel includes a solid cyto hold the jaw t and movable bar l against lindrical body 0 on which strip may be coiled and peripheral displacement. which may be keyed to an axle 2 by keys it, the When it is desired to clamp the end of a strip two parts being as constructed to form a solid to the reel, the end of the strip is inserted beunit which will not collapse even though the tween the adjacent faces of the groove 5 and jaw 20 strip be coiled very tightly. The axle 2 projects 6, the bar '5 being moved to the right so as to beyond the ends of the body i so as to provide permit this. Thereafter the bar is forced to the journals 2 and fluted ends 2 and end portions l left, this causing the jaw to tightly clamp the are connected to the axle 2 and body I in any end of the strip against the side of the groove.

Preferably, the bar should project beyond the 25 Roller bearings t are permanently mounted on right-hand end of the body i a suificient distance the journals 2 close to the ends of the body 0. to permit the use of a hammer in effecting its The housings of these bearings have cylindrical forcing to the left, and it should project to the casings it and integral spaced annular flanges left sufficiently far when forced to its full clamp- 3 and function to mount the reel in suitable ing position to permit the use of a hammer in 30 brackets or to permit the reel to be rolled along forcing it to the right to release the end of the tracks in the manner illustrated.
