Referring now to the drawings in more detail, Figs. 1 to 5 a.nd 7 to 10 disclose varlous embodiments of the invention, wherein the carrier above referred to ls of spherical form, and made.
- netic bar 39.
a plurality of pin-like elements 31, 38 the tapered.
of any suitable matenal, either resllient; or not, insulating or non-magnetic material. Howevger. it is preferable to make the carrier :tor Certaln purposes out of rubber or rubber composltion.
In Figs. 1 and 2, there is shown a. ball-shaped carrier 20 having recesses 21, 21a which may be diametrically opposed and arranged in the surface of the said carrier. Withln said recesses 2I2ia there are located the arcuately shaped perman'ent magnet pieces 22, 22a, the respective upper surfaces of which a1'e coterminus wlth the spherical surface of the ball. The said magnetic pieces may be ceme11ted or otherwise flxed in place within said recesses and besides being utilizable as magnets also serve as instrumentalities to give momentum to the ba.ll 29 when set in motion. It 1s further to be noticed that the magnetic pieces may also act as reinforcing elements for the ball 2ll. This latter purpose becomes more apparent from the disclosure in Figs. 3 and. 4 where the permanent magnet pieces comprise four arcuately shaped members 23, 23a, 23b, 230, a pair of which substantially xtends, respectively, along the circumference of the ball carrier 25, euch pair being substantially a.t right angles to each other. The magnet pieces 23 t.o 230 are inserted in respective recesses,one of whlch is indlcated by numeral 24.
Fig. shows a ball-shaped carrier 26 through which passes a pin 21 made 01 magnetic material. the said pin preferably having fiared ends or tips 28, 29 whose surfaces are contoured 110 conform with the spherical shabe of the said carrier 26. It, is understood that the magnetic piece 21 may comprise an integral member, as shown in Fig. 5, o1 may be bullt up from two or more pieces, which are threadedly or otherwise connected together.
Flg. 6 shows a disc-shapecl carrier having permanent magnetic elements 31 and 32 which are attached either fixedly or slidably to the circumferential wall 33 and to ab least one of the side faces 34 of said ca.rrier. It is 130 be noted that; part 31a of magnetic element 31 is positioned flush with the rolling surface of wall 33 whereas part 31b of saicl element either projects from side wall 34 or may be even with said side wall 34. By slidably fitting said piece 31 into said carrier 30 part 3Ib may be regulatedly spaced from side face 34. It is umlerstood that either wall 33 or one of the side faces, say 34, may be utilized as the contacting surface with a suitable support (not shown), so that either part 31a o1 3lb may be the utilized part of the magnetic piece 3I.
In Fig. 7 centrally disposed within ball-shaped carrier 35 is a substantially rectangular mag- Driven within ball carrier 35 is or pointed ends of which contact the said bar 36, whereas the head portiong 31a, 38a are substantially flush with the outermost surface of said carrier 35.
In Fig. 8 the ball carrier 39 contains a similar bar magnet 49, the pin-like elements 4l, 42 being however dlsposed such that the respective heads thereof 41a, 42a are in close contaet with said bar 40 whereas the pointed ends 4lb and 42b slightly project b. yond the outermost curved surface of ball carri-ar 39.
In Fig. 9 the ball-shaped carrier 43 is provided with a; horse-shoe magnet 44, which ends are ca.rried to the surface of said carrier and are joined by a keeper or rmature 45, the latter being preferably secured to said carrier at 46 in any sultable manner. A bar magnet 41 may also be placed withln ball 43, edges 48 of which bar may slightly project from the surface 43 of said ca.rrler. The lnner end. 01 bar 41 may be somewhat fiared, as lndlcated by numeral 49 to facilitat securement of sald bar wlthin said carrier.
Flg. 10 lllustrates on an enlargea scale a portion cf ball carrler 43 wlth a parl; 01 horse-shoe magnet 44, the keeper 01' armature shown in Fig. 9 belng ellminated. Edges 50 01 the magnet 44 slightly protrude from the surtace 01 sald ca.rrler 43 to provlde' efiective attra.ction surfaces an said carrler.
Fig. 11 shows 9, carrler 5I barrel-shaped in form provided wlth magnetlc power pleces 52 arranged in spaced apart relation on the curved surface of said carrler.
Figs. 12 und 13 disclose a skeleton or frame 53 having cross arms 54, 55 made of magnetic material anal in which may be contained a. spherical body 56, as shown in Fig. 14. The
curved cross arms 54, 55 thus form part of the arcua te surface of sald b0dy 58.
Fig. 15 shows in top plan vlew a spherical narrier.51 in which there is disposed a magnet bar 58 from the polar area of which extend differently sized elements 59, 50, 5l which conduct magnetic fiux of different intensities to various .points cf the surface of carrler 51.
Figs. 16 und 17 illustrate a spherical bocly 62 in which is centrally located a magnetic eure 63 with which contacts a pin-shaped mernber 64 conductin g magnetic power flux 1:0 the surface of said body or carrier 62 and which further counects with a. secondary conductor 65 removably positioned at the surface of the body 62, the said c0nductor 65 having a projection 66 embedded in the material of body 62.
In Fig. 18 the carrier 61 has magnetic bar 68 embedded in its spherical surface and connecting with a conducting member 89. Member 69 is preferably pivoted at 10 110 bar 68 and is providecl With a. pin H to secure the said member 69 at any desired location of said surface determinecl by said pivot connection I9.
The aforesaid devices each including a carrier and magnetic power means connected therewlth may be employed for numerous purposes, as lt will be easily realized.
It is obvious from the above disclosure that a device of the aforesaid nature may be utilizecl particularly in games, wherein magnetic attraction o:f object or objects is desired during various stages of the game.
Fig. 19 shows examples how, for instance, the invention may be employed. There is disclosed, for example, one row of objects I5, I6, 17 made of material which may be attracted by 2. magnet, as, for instance, sheet iron and which may carry suitable indicia such as numbers 2 5, 3, etc. Ball carrier 78 has the magnet 19 ancl it is evident that by rolling the ba1l 18 along the surface 80 and in alignment with one of said objects, say16, the carrier'may pick up by means of its magnet 19 the said object IG. It is of course necessary tha.t the object 16 be in the pa.th cf the rolled magnet I9 to be attracted and kept thereby.
Again the top 81 which carries the magnet 82 may be spun on im pivot 93 by means of a handle 84 in the dlreiztion of the object 85 resting in standing position on surface 89, the said object 85 being made o f a material, such as sheet lron.
wh1ch lends 1tself to belng attracted by said mag net 82.
As the top 8I skims past object 85 the 1atter will be attracted. or displaced by the magnetic influence o1 magnet piece 82.
Although I have described my: improvments w1th conslderable detail and with respect to certain partlcular f0rms of my inventlon. I do not deslre to be lim 1ted to such detail since many changes and modlfications in the torm, arrangements, proporti0ns and sizes thereof may well be made without departing from the splr1t and scope of my invention in 1ts broadest aspect.
