.2,610,233 r soLnNolD con. sUrPoR'r Anewn. Caldwell, Ballston Lake, N. Y., assignor to General Electric Company, a corporation of New York Application July 12, 1950, Serial No. 173,425
2 Claims. l
My invention relates to solenoids and has for its purpose the provision of a simple, inexpensive and effective means of accurately holding the coil of a solenoid in its C-frame support.
Former methods of positioning a hollow coil in a solenoid spaced the outer surface of the coil with respect to the frame of the solenoid. The plunger operates within the space enclosed by the coil, so that the thickness of the coil between the inner and outer surfaces was required to be maintained rigidly to prevent interference of the plunger stem with the inner coil surface. Since the body of the coil was built up by successive applications of liquid insulating material it was dililcult to maintain constant spacing between the inner and outer surfaces. To eliminate this difficulty I conceived the idea of locating the coil with respect to its inner surface.
In carrying out my invention I provide a laminated C-shaped magnetic frame for a solenoid having inwardly extending stubs on the ends of the frame arms to restrain a hollow operating coil within the C-frame. A pair of tongue plates supported by the frame extend into the hollow of the coil and contact the inner surface of the coil to restrain transverse motion of the coil with respect to the frame.
For a better understanding of my invention reference is made to the acompanying drawing in which Fig. 1 is an elevation of a solenoid incorporating my invention; Fig. 2 is an end View of the solenoid; Fig. 3 is a view along 3 3 of Fig, 2 looking in the direction of the arrows; Fig. 4 is a view along 4-4 of Fig. 1 looking in the direction of the arrows and Fig. 5 is a view along 5-5 of Fig. l looking in the direction of the arrows.
According to the drawing a coil I is positioned between parallel arms 2 and 3` of a laminated C- frame 4. Coil I is held axially against the intermediate member 5 of frame 4 by stubs 6 and 'I extending inwardly from arms 2 and 3 respectively. A stem 8 of a plunger 9 reciprocates within a plunger aperture provided in coil I. A yoke Ill is secured to frame 4 by bolts II. The inside surface of the horizontal portion I2 of yoke I is provided with a thin cushion I3 of resilient material to limit the stroke of plunger 9 out of coil I. The head of plunger 9 secured to the stem is constructed wider than the opening between stubs 6 and 'I to limit the movement of plunger 9 into coil I. Flat tongue members Il centrally disposed between the upright members of yoke IU extend within and contact the inside surfaces I of coil I to restrain the coil against (Cl. F-338) transverse movement with relation to frame 4.
In the arrangement of the solenoid according to the above description the inside surface of coil I is positioned with respect to frame 4 so that the outer transverse dimensions of the coil are no longer critical. As long as coil I fits between the arms 2 and 3 the thickness between the inner and outer surfaces of the coil is immaterial. Also interference between plunger 9 and coil I is eliminated, since plunger 9 must reciprocate between legs I4 of yoke IIJ.
While a particular embodiment of this invention is illustrated and described modifications thereof will occur to those skilled in the art. I
desire it to be understood therefore that this invention is not to be limited to the particular arrangement disclosed and I intend in the appended claims to cover all such modifications which do not depart from the spirit and scope of this invention.
What I claim as new and desire to secure by Letters Patent of the United States is:
1. In combination, a solenoid comprising a laminated C-frame including a pair of parallel arms and a member joining a corresponding pair of the ends thereof, said parallel arms having a pair of stubs projecting inwardly from the opposite ends thereof, an operating coil having a plunger aperture therein and provided with an inside surface surrounding said aperture, said stubs restraining said coil axially against said joining member, a yoke secured to said frame and provided witha plate portion perpendicular to the axis of said coil and flat tongue members secured to said frame and extending Within said aperture, said tongue members contacting said inside surface to secure said coil transversely with respect to said frame and a T-shaped plunger having a stem portion slidably disposed within said aperture and between said tongue members and a head portion wider than the opening between the ends of said arms and disposed between said plate portion and said arm ends to restrict movement of said head portion therebetween.
2. A solenoid comprising a laminated C-frame including a pair of arms and an intermediate member joining said arms, an operating coil provided with an axial plunger aperture therein, means for restraining said coil axially against said intermediate member, a yoke member including a plate portion disposed opposite the ends of said arms and tongue portions secured to opposite faces of said C-frame and extending into said aperture to restrain said coil transversely Within said C-frame and to form guides therein, a T-shaped plunger having a stem portion sliclably disposed Within said aperture and between said guides and a head portion wider than the opening between said arms and disposed between said plate portion and said arm ends to restrict movement Yof said head Aportion therebetween. i f
