To all whom 'it may con-cern:

Be it known that: l, S'iewnnfr (j. Conr, a citizen ot' the United States, residing:r at Youngstown, in the county' oi h'lahoning and State of Ohio, haviinventi-il new and useful Improvements; in '.vlagnetic flcclp Charging lachines. of which the ii'ollo'\.\'ing is a el'ieciiication.

My inventiox'i relates to machines for charging skclp into heating iilrnaces preparatory to 'welding the :skein into tubes, or to bending the saine imo other products.

The objects of this invent-ion are to pro vide a rapid, simple and positive means for charging skelp or other blanks oi a niagnetic or inagnetizabie nature into heating furnaces by the use of a magnet carried by a suitable framework or charging table having travel across the charging end of the furnace.

Referring to the accompanying drawings, Figure l is a longitudinal. `"faction through the shaft on which the coi' 'ing magnet mounted, parts being s ihoxn in elevation; Fig. 2, an end f iloifationo'f n striictllre on bodying i'ny invention Fig. a nien of the saine; and Fig. at, an elevation showing the 1 end opposite that shown on Fi 2, a portion of the furnace being shown in section.

lOn the dra-Winge., l represents a pair of' rails on which the wheels 2 ot the charging table 3 travel.

et is a portion of a heating furnace across one end of which the t-abie may 'travel back and forth. The ton of the tabie has two levels, the upper ci x v" preparatory to being; it n. f lower level. The sire-lp on the 'opper le lie paraliel to the direction in which they are to be charged into the furnace. They are xifioved laterally by Workmen or by any suitable means so as to 'cause them to reach their proper position on the lower level now to be described. The said lower level which may be at any desired distance below the upper level is shown parallel to the same. It has the conveying trou rh or channel 7 open upwardly, there being 1n the bottoni of the channel a number oftransverse rollers 8 on which the skelp travel with but little friction during the chargin operation in order to li h ten the work of t e charging magnet. At e end .of the charging channel or bed 7 I glace one or more rotary charging ma nets 9 aving its axis. of rotation transverse 'y of the direction in which the skelp is to 'be charged. The magnet preferably projects slightly above the bottom of the channel 7. The magnet is driven by the motor 10 connected flieg-:cio by suitable gearing soA as to cause iin; tcp of thc magnet to rotate toward (he .fur

l1 .is .,.uitablc shaft, prf-.feralily of iron or steel, upon which l mount the core or 'spool lil., having thereon the coil 13 of Wire. The terminals 1 4 andi?) of the coil lead 11especti'vc'ly 'to the collector rings 16 and 17, carried by the core 1S on the shaft 11. The coil 13 and its spool 12 are inclosed in the cylindrical iron or steel cases 19 which are magnetically'separated by the ring 2O of brass or other non-magnetic material, this ring being at about the center line of the skclp. The outer ends of the cases 1 9 are and connected to the shaft 11, the when the magnet is idle, be-

magnetic flux, nig along the bodies of .the cases 1-9, and across the nonmagnetic gap occupied by the ring 20.

"v'Vhen a slrelp is taken from the charging level 5 und placed in the trough 7 with one end resting on the bodies of the cases .1,9 and bridging the gap occupied by the brass ring 20, thc .magnetic fiux just described is largely di rerted so as to travel transversely through the skein at' and about its line of contact 'with the periphery oft the magnet. The ro- (ary magnet therciore, a great trac; tine or @i-resin efect on the slrelp and museali t te charged into the furnace at the. surface. velocity ci the magnet. The electric matar i() can, as weit known, be controlled Se ae to gire the slreip such ini tial, final, @mi iiitei'n'mdiate oi'nirging speeds as may pioveirst. After a skelp has been charged into the furnace, the charging table 3 is moved on the rails l to the desired posit-ion for charging another skelp into the furnace.

My invention dispenses with a la-r e number of nien required for the hand ciarging 'of akelig; ci-iinmatesthe danger incidental and save-s by that more than one magnet ay be used at selected places along thel trough, or near tho-Ina'gnet shown.- l I claim- 1.. The combination 'of a furnace, a chargshaft 11, radiately along theing table at one end thereof, and a magnet thereon having surface travel toward the furnace, the said surface being arranged to be. engaged by linear magnetic materials, and to transfer the same to the furnace.

2. The combination of a furnace, a charging table et the end thereof, a rotary ma net having its axis of rotation transverse 0:' the table and furnace, the `magnet bein arranged so that the part thereof whic r0- tates toward the furnace may be engaged by linear magnetizable material.

3. The combination of a table and a rotary magnet supported thereon and having its magnetic circuit interrupted eircumfern lthe table and having its axis o Signed at Youngstown, Ohio7 this 15H' day of' December, 1911.
