the armature in its movement toward and from the magnet. This magnet core 23 is surrounded by a cup-shaped flange 24, between which and the core are arranged the coils of the magnet. tuting the core and its coils, is pivotally mounted on a cross shaft 25. The arm 3 carries a rheostat 26 whose arm 27, which cooperates with the resistance terminals, is over-balanced by a weight 28 (see Fig. 1), which weight tends at; all. times to more the arm 27 so as to cut out all resistance from the magnet windings 29 is a rod. having a roller 30 at its upper end, which roller is arranged under the weighttal end of the rheostat arm. This rod pivotally connected at its lower end to a foot lever 31. nected to the arm 3 and to the foot lever and tends to hold said toot lever and roller 30 elevated at all. times, in which elevated position all the resistance of the rheostat is cut into the magnet circuit. {The upper end ot rod 29 passes through a perforated lug on th arm 2-, which guides the said rod it its movement. The rod slides treely through this perforated lug. and when pressure released from the foot lever, the spring 32 will cause said foot lever to rise and lift the rod so that the weighted end ot the rheostat arm will he ehwaled. \Vhcn the foot lever is depressed the lfl l Qt) is drawn down and eoincidentallv therewith the spring 32 is placed under tension so as to move the main lever 23, causing the sad iron 13 to he lowered against the goods. The armature ":1 will he caused to approach the magnet so as to reduce the air gap hetween the armature and said magnet. and consequently the armature is .--.nh ieeted, by virtue ot its proximity to the magnet. to a strong magnetic influence.

in operation, the cloth to he pressed is arranged in position on the pressing hoard and the iron adjusted over the starting point. The operator then depresses the loot lei er. and the upper end ot lever 23 is awaited 't'orward. The tension of the spring 5: normally holds the rod 29 ele' rated and c use pientlv the weighted end of the lever 27 is elevated and when the foot lever is depressed, the spring 3'3 is expanded and the rod 25) is lowered. thus permitting the weighted end .ot the lever 27 to move downward while the opposite end of said lever i-z etevated therehy cutting out the resistance otter-ed hy the rheostat. and directing the rurrent thr ugh the main Poll of the magn t. in this manner the initial depres sion ol' the loot lever Ill. hy virtue of the strength ol spring It. will unbalance the main lt'\'tl., ll(l cause the iron to he gently hrought into contact. with the cloth to he pre ed wi t hout disturhiug the position oi the rla-ostat. arm which, during this unhal- The magnet. consti- A tension spring 82 is eon-' ancing movementof the main lever, result;- ing from the initial depression of the foot lever, will remain in position to at; in all of the resistance. When the m ement of the main lever is arrested by l waging the iron into contact with the cloth, then a continned depression of the foot lever will expand the spring 32, ahd draw the rod 29 downwardly with respect to the main lever, which downward movement of rod 29 will lower the supporting roller 30 with respect to the pivotal point of the rheostat arm, and permit the weighted end of said arm to move downward gradually, cutting out the resistance. The operator may, by the position of the foot lever, thus control the amount of current admitted to the magnet, after the iron is on the cloth, and when the foot lever is released the resistance. is first cut in so as to reduce the magnetism, after which the main lever, being over balanced, moves to its normal position, and lifts the iron from the cloth, and raises the foot lever. The lower \the foot lever is depressed, the more resistance is cut out, and consequently the magnet becomes stronger until'it reaches its maxim1un va no. The armature disk on the forivard\end ot. the arm 3 is located in the magnetic field and is consequently intiuenced by heing attracted to the magnet, and considerahle pressure may be exerted on the iron 11. The operator has tl amount of pressure exerted on the iron directly under his control. and this pressure may he regulated according to the position of ihe toot. lever. To cut out the magnetic pressure it; is only necessary to release the foot lever and permit it to rise under tension of spring 32 so as to etl'ect the elevation of the weighted end of the rheostat lever. in this uan ner, resistance is cut into the magnet cult and the further upward movement in the foot, lever permits the springs 20 to exert their energies in lifting the iron from the hoard.

in order to neutralize the residual magnetism of the core of the magnetand to avoid a tardy release of the armature dish, from the zone of intluenee ot the magnet resulting from such retained saturation, after the resistance is cut into said circuit, I arrange a high resistance coil (4 on the core 2 3, which high resistance coil is wound in a direction opposite that of the main coil 6 of the magnet, which latter coil is composed of heavier wire.

v is a, switch in the maid line circuit for cutting in and cutting out current to the magnet circuit. The current enters the magnet circuit through wire (5 which is connet-ted to one post of the rheostat 96. A wire 6 leads t'rom the other post of the rheostat through the main coil b of the magnet, and thence hy wire t' ot'the magnet to the return wire ot the main line circuit. The

circuit at all-times, prevents any sparking at the terminals with which the resistance arm coiipe ates, and being in parallel with said rheostat will otter the path for a small portion of the current, the amount of which, passing through the high resistance coil, is determined by the amount of rheostatic resistance cut in the magnet circuit. For instance, normally all of the rheostatic resistance is cut into the magnet circuit tllltlille high resistance coil is energized to its maximum. The armature disk, however, being elevated away from the core of the magnet will, on account of the wide air gap, not be influenced by any magnetic lines of force which might be generated on account of this high resistance coil. In starting the machine, however, the rheostatic resistance cut out of the magnet circuitand as the main winding 7) of the magnet is wound in the opposite direction it will take comparatively few countenmagnctic lines of force to neutralize the high resistance coil d. Then, as more rheos-iatic resistance is cut out, the main coil 1) becomes more power-- fully energized, and the magnet becomes stronger. In cutting in rheostatic resistance in the main magnet winding 7). the reverse is true. lhe coil b becomes gradually weaker until its value is encountered by the high resistance coil, and when the greatest-amount. of rheostatic resistance is cut in, the resistance coil attains its maximum value, which utilized to neutralize the tendency of the core to retain the magnetic saturation resulting from the energization of the main coil 5. there is no lag or tardy In this way, release of the armature disk, and consequcntly the machine is thus made sensitive and instantly responsive to the will of the operator.

. Appropriate means for lubricating the joints of the moving parts is provided,such, for instance, as arranging an oil cup above and a drip cup under the pintle 4, and a spring-pressed, oil-saturated disk under the non-magnetic post 22 which fits loosely in the opening, constituting an oilv well, in the core so as to sustain the magnet in its upright position.
