It will also be understood that the magnet will be employed in each performance illustrated in Figs. 8, 9, and 10, the magnet being omitted from said views, but essential to support the dolly block for each performance set up in said views.
In Figs. 12 to 16, inclusive, is illustrated an arrangement wherein permanent magnets are employed, the structure consisting of a casing rectangular in form, and having a rectangular opening H centrally passing therethrough, the body having side and end walls 30 and 3 i, respectively, externally, and side and end walls 32 and 33, respectively, internally, said walls having a bottom 34 integrally joined thereto, whereby the structure is channel li removable head 35 to close the channel. A plurality of permanent magnets 36 are positioned in spaced relation in the oppositely disposed side channels, said magnets being assembled on their respective shafts 31 and 38 in such a way that the legs of the magnets will extend through opening J in the bottom of the channel. The shafts are iournalled in the outer end walls 3| and adapted to turn in all of the magnets except the magnet at each outer end of each assembly, the latter named magnets being secured to the shafts and rockable therewith, the other magnets being permanently carried by screws 39 passing through the head and into the magnets at their upper extremity. It will be seen that shaft 31 outwardly extends through one end wall and has a crank 40 secured thereto as rocking means for the shaft-and magnets carried thereby, the other shaft 38 being rocked through the medium of a connecting arm 4| that has ends hingedly connected to cranks 42 and 43 respectively that are mounted rigidly on shafts 31 and 38, respectively, as shown in Figs. and 17, whereby the said outer positioned magnets at the ends of their respective shafts are rocked from engagement with their respective leg openings to reduce magnetic power of the magnet assembly for the purpose or reducing friction when the magnet is moved, the function being the same as described for the electromagnets, it being understood that the casing of the permanent magnet arrangement has similar casters positioned in each corner thereof.
And other modifications may be employed as lie within the scope of the appended claims.
