COIL SUPPORTING MEANS Filed Feb. 12, 1945 INVENTOR. EDMUND f. LAPHMg-Jx,
Patented June 28, 1949 COIL SUPPORTING MEANS Edmund F. Lapham, Jr., Norwell, Mass, assignor to Federal Telephone and Radio Corporation, New York, N. Y., a corporation of Delaware Application February 12, 1945, Serial No. 577,489
Claims. 1
This invention relates in general to means for mounting articles and more particularly to means for detachably securing coils wound upon tubing.
It is very often found necessary to change coils in radio and other like instruments. This chang ing of coils has always been a source of annoyance, and at times has been found to be quite difficult. Therefore, it is very important that some form of fastening means be adapted that not only securely retains the coil on the frame of an assembly mounting, but which also facilitates replacement of the coil member whenever it is found to be necessary.
One of the objects of this invention is to provide means whereby a coil member can be easily and securely mounted upon a support.
Another object of this invention is to provide means for automatically securing a coil member into a fixed position on a support upon engagement with a supporting frame.
One of the many features of this invention is the ease with which a coil member may be detachably secured upon a supporting member and then looked to said supporting member.
Another feature of this invention is the positioning of the locking member relative to the coil and coil support so it can readily be removed when a change of the coil is found necessary.
In carrying out one form of my invention I prefer to loosely position the coil member upon a supporting member keyed to a frame, temporarily holding them together by means of a wire-like key member insertable therethrough, and then looking them together by distorting the key member by effecting a relative movement between the coil member and its supporting member.
Further objects and features of this invention will become apparent upon considering the following description when read in connection with the accompanying drawings; in which:
Fig. 1 is a perspective view of my invention exploded to more clearly show its constituent p s;
Fig. 2 is an assembled plan View, partially broken away to more clearly show the co-operation of its parts before the coil supporting member is finally drawn up to effect the locking condition;
Fig. 3 is an end elevational view of Fig. 2;
Fig. 4 is a side elevational view of my invention after the coil supporting member has been 2 completely drawn up and the locking of the parts has been effected.
Referring to the drawings, the coil l is preferably wound upon a tube or hollow cylinder 2. This tube is adapted to be positioned on the coil supporting member 3, which member is in turn adapted to be secured to a frame 4, or other like member, by a threaded nut 5.
It is preferable to first loosely position the coil supporting member 3 in the frame 4 before attaching the coil member I thereto. For this purpose the supporting member 3 is provided with an extended portion 6 of elongated shape which is placed into the opening or recess 1 of the frame, which opening is of approximately the same configuration as the extended portion 6 and serves to key the supporting member 3 to the frame thereby preventing any rotation thereof. To loosely secure the supporting member 3 to the frame 4, the supporting member is further provided with an externally threaded portion 8, extending coaxially from the firstmentioned extension 6, and to which the nut 5 is threadably engaged.
Having thus loosely positioned the coil supporting member 3 on the frame 4, the coil member I and its tubing 2 is then placed into position upon the coil supporting member. The large disc-like portion of the supporting member 3 has an external diameter slightly less than the internal diameter of the tube 2 whereby the tube 2 telescopes thereupon. It will be understood, of course, that the member 3 may be otherwise constructed if desired. For example, the member 3 need not be arranged to be received within the tube but the relation between these parts in this respect may be reversed. The article to be supported may also comprise a shape other than a hollow tube.
To detachably secure the tube 2 to the supporting member 3, the tube 2 is provided, adjacent one end thereof, with two pairs of oppositelydisposed holes or openings 9, 9 and the disc-like portion of the supporting member is provided with a pair ofsubstantially parallelly spacedapart openings or grooves Ill, I0 substantially midway between its two faces. However, as the distance from the holes 9, 9 in the tubing 2 to one end thereof is slightly greater than the distance from the openings [0, ID in the disc-like portion to the same respective end, the holes 9, 9, when aligned with openings [0, l0, permit the end of the tubing to extend slightly beyond the one face of the supporting member 3.
To hold the coil I in position on the supporting member I and the frame 4, a securing key ll preferably.of resilient wire, is provided. This securing key is preferably formed approximately U-shaped to provide a pair of legs which are placed through the holes 9, 9 in the tubing 2 and the openings l0, ID in the supporting member 3 to loosely hold the tubing 2 to the supporting member preparatory to the coil i being either detachably secured into position or for its removal.
To loosely lock or secure the coil i into fixed position with respect to the supporting member 3 and the frame 4, it is only necessary to rotate the nut and thereby draw the supporting member toward one face of the frame 4 as clearly shown in Fig. 2 of the drawings. Further rotation of the nut 5 will move the supporting member 3 further toward the face of the frame 4- while the tubing is held against endwise movement by abutting the frame. This relative movement between the tube 2 and the supporting member under the action of the threaded nut causes a disalignment of the holes 9, 8 and the openings l0, ID with the result that the securing key II will be distorted, thereby binding the tubing to the supporting member. This result is best seen in Fig. 4 of the drawings.
If and when it is found necessary to remove the coil or change the coil for another, the nut I is slightly loosened to realign the holes 9, 3 and the openings i0, i0 thereby releasing the securing key i I so that it can be withdrawn for the purpose mentioned above.
Should the coil admit of a tuning element, the supporting element 3 may be provided with a coaxially located opening, which may be threaded or not, depending upon the type of adjusting mechanism to be used for the tuning element. In the Figs. 1 to 4 inclusive, I have shown a tuning element l2 fastened to one end of an externallythreaded rod l3, which rod is threadably engaged in an internally threaded opening i4 located substantially coaxially in the supporting member 3.
While I have shown and described one embodiment of my invention, it is to be clearly understood that such illustration is made only by way of example and not as a limitation on the scope of the invention as set forth in the foregoing objects and accompanying claims.
I claim:
1. Means for securing a hollow, cylindrical member to a support comprising a frame having an opening therein smaller than the diameter-of said member, a supporting member, said cylin drical member having openings in its periphery adjacent one end thereof, said supporting member having a portion in peripheral engagement with said cylindrical member intermediate the ends thereof and having openings in said portion in alignment with the openings in said cylindrical member, said supporting member having another portion adapted to extend through the opening in said frame, a resilient key member insertable through the aligned openings in said cylindrical member and said supporting member and means adjustable longitudinally of said cylindrical member to secure the portion of said supporting member extending through the opening in said frame for causing said cylindrical member to abut against said frame whereby said key member is distorted.
2. Means for securing a hollow, cylindrical member as claimed in claim 1, wherein the portion of said supporting member extending through the opening in said frame is threaded.
3. Means for securing a hollow, cylindrical member as claimed in claim 1, wherein said cylindrical member has two pairs of oppositely disposed openings in its periphery adjacent one end thereof and said supporting member has openings therein for alignment with the openings in said cylindrical member and said key member is U- shaped, the legs of which are insertable through the aligned openings of said cylindrical member and said supporting member.
4. Means for securing a hollow, cylindrical member as claimed in claim 1, wherein a wire coil is wound about said cylindrical member.
5.
