the curved end thereof in a plane extending transversely to the parallel sides of the end plate. 'Ihe end plate 9 is slotted at I0 to avoid the establishment of a closed circuit path through the end plate adjacent the electromagnetic winding for preventing the setting up of undesirable eddy currents.
The end flange I I formed from plastic material has the face thereof recessed at IIa in a contour which conforms with the shape of the curved end of the end plate 9 for receiving the end plate 9 for thus reinforcing the plastic end flange and preventing warpage thereof.
The plastic end ange I I has embedded therein the thin flat sheet-like terminal plates I2 and I4. The terminal plates I2 and I4 are arcuate in shape and extend for distances substantially less than a quadrant. The terminal plates I2 and I4 have eyelet lug connectors IZa and I4a at one extremity thereof and lug connectors I 2b and I4b at the opposite ends thereof respectively, The eyelet lug connectors I2a and I4a serve as terminals for the opposite ends of the coil of the electromagzletic winding I5 while the lug terminals I2b and I4?) serve as terminal means for establishing connection with an external electrical circuit. The terminal plates I2 and I4 are apertured at spaced intervals as represented at I2c and |40 allowing the passage of the plastic material of the end plate II therethrough for firmly anchoring terminal plates I2 and I4 in embedded position within the plastic end flange I I.
The electromagnetic system as thus described is associated with the frame support I through fastening screw 3 able armature I6. The armature I6 has longitudinally extending actuating arms I6a and I6b thereon for operating spring pile-up assemblies supported by the magnetic frame I. provided on an extension of the armature I6 and serve as supporting means for the armature with respect to the projections Ib of the magnetic frame I. The armature I6 is maintained under tension by means of flat spring I8 which exerts continuous tension against the edge of the arma- A spring pile-up assembly is represented generally at 2i arranged for operation by arm Ib of the armature I8. A second spring pile-up assembly may be supported on the frame I for activation by the arm Ilia of the armature I6.
The method of reinforcing the plastic end plates 5 and II of the electromagnetic system by stiff metallic members and the method of embedding the terminals in the material of the plastic end plate I I has proved to be very effective in manufacture, production and use. I realize that modification may be made in detail in the structure of my invention and I desire that it be understood that I intend no limitations upon my invention other than may be imposed by the scope of the appended claims.
What I claim and desire to secure by Letters Patent of the United States is as follows:
