DAVID B. MARWICKOF NEW BRITAIN, CONNECTICUT, ASSIGNOR OF oNE- HALF TO ETHELBERT A. MOORE,

To all whom it'mwy concern:

Be it known that I, DAVID-B. MARWICK, a

citizen of the United Stateiresiding at New Britain, in'the county of Hartford and State of Connecticut, have invented certain new and-useful Improvements in Machines for Bundling Scrap, of which the following is a specification. This inventionrelates to means for form- 1ng scrap into rolls or" balls, and hasfor its objectthe provision of a machine by which the accumulated scrap may be-readily with drawn from the floor of amill and coiled and consolidated into a compact portable ball or bundle,

v ready for any subsequent procedure desired. 7

" A further object of the invention is the provision of a mandrel for windingthe scrap,

and in connection with said mandrel, a device cooperating therewith in the formation of said scrap into a consolidated mass, ready for transportation, or for admission into a reheatingor melting furnace.

A further ob ect of the invention isv theprovision of meanswhereby the device coopcrating with the mandrel'may be shifted to dislodge the compacted ball or mass from the Y mandrel.

' which the .vention. machine, Fig. 3 is a detail, partially in sec- A further object of the invention the provision, in connection withthe devicefor com acting and governing the formation of I the all ormass of scrap, of a taperedmandrel havin means for instance, a slot, in.

first strand of scrap may be inserted, the subsequent intermingled scrap being drawn forward by said first strand secured in any suitable way to said mandrel.

Other objects of the invention relate to de tails which will be hereinafter-described. In the accompanying drawings, Figure '1 is a plan view of a machine embodying myin' Fig. 2 is a front elevation of said tion, showing a ball of scrap in readiness to be discharged from the mandrel. Fig. 4 is .a

view, partially in sectionand in elevation,

illustrating the mode of feeding the scrap in the-formation of the ball, the section being taken-on line 44 of Fig. 3, looking in the di-.

rection of the arrow. Fig. 5 is .a longitudinal, horizontal section, taken on line 5-5 of Fig.2, and Fig. 6 is a transverse section taken on hne 6--6v of Fig. 5., looking in the direction of the arrow.
