Working model of a patent electro-magnetic engine,yth oscillating motion and four inches stroke. ThePeculiar features of this invention are, that any length ofroke with a direct pull, of a succession of polar extremi-le s, extending to the whole periphery of the acting surfaces,^ iri he produced, and that the destroying effect of the.Parks is prevented; the power has been found to increasea simple ratio to the diameter of the piston,t; '' r °°4en model of the same, of an improved construc-° n > hy which a stroke can be made of any length withfix l 0110 ma g lle t; one pole consisting of three coiled ringsCQ .f to two plates, and the other of a single ring likewiselle o, forming the piston, the motion of which is guided
by rollers; the rollers at the same time serve as a meansby which magnetic contact is established between tbspiston and the stationary part of the magnet. The modelrepresents a vertical section of the arrangement, and itwill be seen that it allows any length of stroke, with anunlimited extension of the diameter of the pistons.
The following is a description of the improved electro-magnetic arrangement, represented in plan and sectionin the accompanying drawing. This arrangement con-sists of only one hollow electro-magnet, the respectivepoles of which are divided in three square rings, aaaand add, being conical inside and outside, connected withthe bows h, by means of the cross pieces £ e. From thetop and bottom of this arrangement, extend from thesaid bows, four plates d, with ribs which are connectedin the centre with corresponding brass-plates and ribs e.These plates are applied for guiding the motion of thepiston f serving at the same time as a means by whichmetallic contact may, during each stroke, be establishedand broken between it and one of the respective poles.Four pair of rollers are for this purpose placed insidethe piston on hollow shafts, which are arranged each onthe four-way principle, with a ring or cylinder, laid inwith diamagnetic metal between the bearings and shafts,so that the magnetic part of the bearings may bobrought in contact either with the similar parts of therings, or the diamagnetic parts of the same. The requiredmotion of the rings is produced by the cranks of g g andg'g', which are connected with the connecting-rod h bythe smaller rods i, so that each pair of the cranks move inopposite directions. In the position represented in thedrawing, magnetic contact is established between the north
