I COIL MOUNTING CLIP Filed June 25, 1949 iNvENToR'.

WILMER H. CHuRcH LL,
Patented Mar. 24, 1953 COIL MOUNTING CLIP Wilmer H. Churchill, Wellesley, Mass., assignor to United-Carr Fastener Corporation, Cambridge, Mass., a corporation of Massachusetts Application June 25, 1949, Serial No. 101,307
The invention relates to a snap-in clip for mounting a cylindrical part to a support and more particularly to a snap-in clip for mounting a cylindrical radio coil form' having a coaxial core-adjusting screw on a sheet metal support.
The oscillator coil for television sets comprises an elongated cylindrical core member having a predetermined number of windings and an axially movable core therein adjustable longitudinally of the coil. Satisfactory operation of the device requires that the core be accurately positioned in the coil and this has'been accomplished by the use of an adjusting screw rotatable in and extending coaxially from one end of the coil. This arrangement, however, has not proven v entirely satisfactory since the adjusting screw tends to creep or turn in its support due to vibration or other causes and thus varies the position of the core in the coil with consequent adverse effects on operation.
is the provision of a simple and efficient snap-- in clip for mounting a coil form in a support wherein improved means are provided for tensioning the adjusting screw against accidental turning.
Another object of the invention is the provision of an improved snap-in clip for mounting a coil form in a support wherein the coil form is positively gripped to prevent accidental displacement or turning thereof.
These and other objects and advantages of the invention will be apparent to persons skilled in the art from a consideration of the attached drawings and annexed specification illustrating and describing a preferred embodiment of the invention.
In the drawings:
Fig. 1 is a side elevational view of the improved snap-in clip of the present invention as viewed from the bottom in Fig. 2;
Fig. 2 is a top plan view of the clip;
Fig. 3 is a bottom view of the clip;
Fig. 4 is a side elevational view of the clip as viewed from the left in Fig. 2;
Fig. 5 is a partial sectional view of the clip as- 2 Claims. (Cl. 248'2'7) 2 r sembled with an oscillator coil and mounted in a panel; and Fig. 6 is a sectional view of a portion of the assembly shown in Fig. 5 taken at right angles to the view of Fig. 5 i
Referring now to the drawing the snap-in clip of the present invention comprises a generally U-shaped member Ill which may desirably be pressed out from a shaped blank of resilient sheet metal such as spring steel. The bottom. I I- of the U-shaped member Ill constitutes the base of the device and is provided with a threaded opening or helix l2 to receive the threaded adjusting screw l3 of a coil l4. The part to be supported, such asthe coil I, may be of a type frequently used as an oscillator coil of a television set and in general co nprises a sleeve I 5 having a winding l6 thereon connected to suitable terminals (not shown) and a core ll longitudinally adjustable in the sleeve l5 by the adjusting screw 13. The adjusting screw I3 may have a slot l8 in the end thereof for-engagement by a suitable tool such as a screw driver or the like. 7 j
Extending upwardly from the base I l of the U-shaped member [0 are a pair of oppositely positioned arms I9 and 20 which carry at their upper ends wing portions 2i and 22. The wing portions 2| and 22 extend laterally outwardly from the arms l9 and 20 preferably at an acute angle thereto so as to tension the device when positioned in a support 23. One of thewing portions is provided with a small tongue 24 turned downwardly therefrom adjacent the end thereof and adapted to engage an opening 25 in the support to prevent rotation of the device.
In accordance with the present invention the arms [9 and 20 are formed with upper relatively wide supported part or coil- engaging portions 26 and 21 and lower screw-engaging portions 28 and 29. The coil-engaging portions 26 and 21 are shaped to snugly engage the lower surface portions of the coil [4 and for this purpose are preferably curved on arcs of a circle having a diameter substantially equal to the diameter of the coil. By virtue of the inherent resiliency of the arms l9 and 20 the portions 26 and 21 firmly grip the coil to prevent turning or accidental dislodgment thereof from the clip. Additional means for preventing turning or dislodgment of the coil are provided in the form of pointed projections 30 and 3! which extend outwardly and downwardly from the opposite edges of each of the portions 26 and 21 and are turned inwardly slightly at their pointed ends so as to bite into the sleeve 15 of the coil. This arrangement plus the inherent gripping power of the portions 26 and 21 insures that the coil will not turn in or he accidentally displaced from the clip.
The portions 28 and 29 of the arms l9 and 29 represent an important feature of this invention in that they subject the adjusting screw .!3 to tension friction to prevent accidental turning thereof from a predetermined adjusted position. This is accomplished by reversely bending the portions 28 and 29 so that the curved portions '32 and 33 thereof yieldingly engage opposite sides of the adjusting screw. The gripping action thus exerted by the curved portions 32 and 33 creates suflicient frictional resistance to prevent accidental turning of the adjustingscrew but permits ready adjustment thereof by a suitable tool.
The base portion l I also carries the latch arms 34 and 35 which extend upwardly therefrom in slightly diverging relationship and terminate short of the wings 2| and 22 by an amount equal .110 the thickness of the support to be engaged.
The latch arms 34 and 35 are positioned between the arms I9 and 29 and are adapted to engage the underside of a support as shown in Fig. 6.
The assembly of the device of this invention with a coil and the installation of the assembly in a support is very simply accomplished merely by inserting the coil in the U-shaped member it and then inserting the U-shaped member ID in an apertured support until the latch arms 33 and 35 snap outwardly into engagement with the lower face of the support. This flexes the wings 21 and 22 upwardly an amount depending on the thickness of the support and securely anchors the clip in the support so that it will not wobble or move around. Rotation of the clip is prevented by the key 24 which is positioned in an opening .25 of the support. Rotation and accidental dislodgment of the coil from the clip is prevented by the gripping action of the portions .26 and 21 and the projections 30 and 3|. Accidental rotation of the adjusting screw is prevented by the tensioning action of the curved.
It will thus be seen that the present invention provides an improved snap-in clip for coils and the like wherein the coil is securely held against rotation or accidental dislodgment and the adjusting screw is tensioned against accidental rotation. Although illustrated and described with particular reference to its use as a mount or holder for an oscillator coil of a television set it 4 will be realized that the clip of this invention may have a wider application to coils and articles of a similar nature.
Various modifications of the invention described and illustrated will most likely occur to those skilled in the art to which the invention relates and may be made without departing from the spirit of the invention, the scope of which is indicated in the attached claims.
I claim:
1. A snap-in clip for attaching a coil to an aperturecl support comprising: a base portion having a central opening and screw thread engaging means for engaging a bolt which may be disposed to extend through said opening; oppositely positioned arms extending upwardly from opposite side edges of said base portion, said arms including portions at their outer ends for engaging a coil form which may be disposed therebetween and inwardly curving portions adjacent the base portion providing opposed surfaces for frictionally engaging such a bolt at points axially spaced from said base portion; outwardly extending lateral flanges extending from the outer ends of said arms to provide surfaces for engaging one face of such a support adjacent the aperture therein; and oppositely disposed resilient latch arms extending from said base portion intermediate said first-mentioned arms, said latch arms extending upwardly and outwardly to dispose the free ends thereof in engagement with an opposite face of such a support.
2. A snap-1n clip in accordance with claim 1 wherein the coil form engaging portions include pointed projections extending inwardly and downwardly therefrom and adapted to bite into the side wall of a coil form to prevent rotation or accidental dislodgment of said coil form.
WILMER. H. CHURCHILL.
