ELMER C. POOL, OF NEW CASTLE, PENNSYLVANIA.
Application filed March 30, 1921. Serial No. 456,864.;
To all whom it may concern:
Be it known that I, ELMER C. Poor, a citizen .of-the United States, and resident of New Castle, in the county of Lawrence and State of Pennsylvania, have invented certain new and useful Improvements in Conveying Mechanism, of which the following plate, and without disturbing the position of the plate or plates next to the one being moved.
The primary feature of my invention is to provide a magnetic conveyerfor conveying metal plates or sheets from a pile, or singly, if desired, having a plurality of diametrically disposed poles around its periphery adapted to contact with the face of the outermost plate, and to so spread the path of the magnetic lines or circuits over the plate that there is no tendency for any of the magnetic lines to pass therethrough into thenext adjacent plate or plates, such terminals or poles being of such form as to concentrate the lines of force into a relatively small area when entering the plate;
thereby increasing" the pull or. holding power of the magnet.
Referring to the accompanyin drawings: Figure 1 is a side elevation 0 a magnetic conveyer co structed in accordance with my invention.
Figure 2 is a sectional elevation line 11-11 of Figure 1.
Figure 3 is a sectional end elevation of the conveyer.
Figure 4 is a side elevation ofa modified form of conveyer. v Figure 5 is a cross sectional elevation on the line VV of Figure 4.
Figurejfi is a side elevation of another modified form of conveyor utilizing an acon the tive magnet to compel plates to adherethereto.
Figure 7 is a cross sectional elevation on the line VII-VII of Figure 6. Figure 8 is a side elevation of still another modified form of conveyer.
Figure 9 is an end elevation of the conveyer of Figure 8.
Figure 10 is a sectional elevation on the line X-X of Figure 9.
-Figure 11 is a plan of a modified form of magnet adapted to be used with the conve er'of Figures 8, 9 and 10. e v
eferring particularly to Figures 1 to 3 of the drawings, the numeral 2 designates a permanent magnet which is mounted within a pair of hollow cylindrical casings 3, having their inner ends spaced apart and joined by a non-magnetic hollow cylindrical tubular member 4. Suitable stub shafts 5 are threadedinto the outer ends of the casings 3 and serve to support the magnet for rotation.
The hollow cvlindrical casing members 3 are formed from soft iron or other suitable material which will readily convey the circuit or attracting forces from the magnet 2, thus forming unlike poles through which a circuit will be completed when they contact with a metal plate to be conveyed.
ing members 3 is fluted, forming a series of diametrically disposed knife-edge ribs or projections 6 adapted to successively engage the plate being conveyed, as the conveyer is rotated. The projections ,6 on the opposite/members 3 will form opposite or unlike pole contacts, adapted to complete a The outer surface or periphery of the cas-' circuit through the plate they contact with.
The knife-edgepole contacts 6' serve to concentrate the forces of the magnet in the immediate'plate being conveyed, and, there fore, when the plate being conveyed is taken from a pile of plates, the lines of force are prevented from spreading into the next adjoinin'gplate and only one plate will be moved by the magnet.
1 In Figures 4 and 5 I have shown a slightly modified form of conveyerin which 8 designates a central shaft or core of nonmagnetic material upon which is mounted a pair of cylindrical pole members 99 composed of soft iron or other similar material. The members 9-9 are provided with diametrically disposed slots 10 spaced around their periphery for the reception of permanent magnet bars 11, which extend across both the members 9- 9.
The walls of the members 9--9between the slots 10 are beveled, forming knife-ed e ribs or projections 12 adapted to successive y engage the plate being conveyed. as the de using permanent magnets.
vice is'rotated. The projections 12 on the opposite members 99 W111 form opposite in the slots 10.
slots 10by a tie ring 13 or othersimilar device.
In Figures 6 and 7 I have shown a slightly further modified form of conveyor, in which 14 designates a central shaft or core composed of soft iron or the like magnetic material, upon which is mounted a pair of cylindrical pole members 15-15 of like material. The members 15 15 have their inner ends recessed for the reception of the ends of a spool 16 of an active magnet coil 17 The spool 16 is journaled for free rotation on the shaft or core 14, and is enclosed by the tubular shell 18 whlch has a fluid tight connection with the spool 16. The spool 16 and shell 18 are preferably formed of brass or other non-magnetic metal.
The shell 18 has an apertured and internally threaded boss 19 extending therefrom, and a conduit 20 is threaded therein through which the power lines are run to the coil 17.
The pole members --15 have their peripheries grooved or tedfforming a series of diametrically dispos o knife-edge ribs or projections 21 adapted gage the plate being conve.
. 11 Figures 8 to 10 I have shown still another modified construction of conveyer In this construction 26 designates a spider member which has its ends reduced forming bearings 27, and is preferably composed of brass or other non-magnetic metal.
'The spider member 26 com rises a body portion having diametrically isposed pairs of arms 28. A U-shaped. permanent magnet 29Lis secured to each pair of arms 28, and
has knife-edge line contact plates 30 secured to each pole adapted to successively engage.
the. plate being conveyed.
net adaptedto be substituted for the permanent magnets of Figures 8 to 10, which comprises a U-shaped core member 32 having a coil 33 wrapped thereon and having knifeedge contact plates 30 secured to each pole adapsed to engage the article to be conveye It will thus be seen that I have provided the The bars 11 are adapted to be held in the .o successively enconveying a single*plate from a pile of plates without disturbing the other plates of pile.
While I have shown and described a permanent magnet for energizing the pole members of some constructions, and active magnets for others, it will be understood that either form'of magnet'may be used, and various other modifications may be made within the scope of the appended claims without departing from the spirit ofmy in-.
