MOUNT I NG Filed Nov. 10, 1936 Patented Dec. 13, 1938 UNITED STATES PATENT OFFICE 3 Claims. 1 ((1248-27) The present invention relates to a suspension mounting and more particularly to a device for retaining a" condenser, coil, resistor or other electrical component or unit and mounting this unit in a predetermined adjusted position in an opening in a radio or other electrical chassis or frame. Among the objects of the present invention is to provide a novel suspension mounting and support for such'mentioned units having longitudinally spaced resilient gripping members adapted.

I to biteinto and resiliently but firmly grip and amaintaih the unit in axial alignment with the mounting device and in a predetermined ad- Qfjustdjlorigitudinal position.

' A further object of the invention is toprovide mechanism for resiliently mounting such a unit or component in the chassis or frame of a radio with the required snugness to hold it firmly in 29 place, but at the same time with suiiicient resiliency to withstand severe shocks encountered in handling and shipping the device.

A furtherobject is 'to provide a novel mountingdevice so formed and constructed as'to be resiliently but firmly retained. in the frame or chassis of a'radio set, and in turn, resiliently and Y firmly retain a condenser or other electrical unit or component. By this construction and ar-.

trangement, the mounting and/or the electricalunit may be quickly assembled, removed or replaced when the occasion requires.

' A still further object of the present invention is to provide amounting device in which the entire mounting operation may be completed llwithout the use of-any, tools, jigs, etc., and by vides mountingwith oppositely projecting resil-" ient members so'formed as to resiliently grip I and retain a condenseror other electrical unit of component, andalso lock this unit in a firm but pressure release position in the chassis or frame.

Further objects are to providea construction of maximum simplicity, 'efilciency, economy and 60 case of assembly and operation, and such further objects, advantages and capabilities as will later more fully appear and are inherently possessed thereby.

The invention further resides in the construell tion. combination and arrangement of illustrated in the accompanying drawing, and while, I have shown therein a preferred embodiment, it is to be'understood that the same is susceptible of modification and change, and comprehends other details, arrangements of parts,

. features and constructions without departing from the spirit of the invention. I

Referring more particularly to disclosures in Figs. 1 and 2, the novel mounting device preferably consists of an annular flange or base of metal and formed or provided with a central opening and longitudinally spaced resilient srip's 2 and 3 projecting in opposite directions. In its preferred form this mounting'is made of a stamping with the longitudinally spaced sets of resilient grips 2 and 3 in staggered relation and so formed 7 and arranged that one of them extends upwardly and inwardly and the succeeding one extends in a downward and inward direction 1 to resiliently grip an object at spaced points and thereby provide a more firm mounting or support therefor. These members are constructed of resilient and tempered metal and so shaped and arranged as to, resiliently but firmly grip at longitudinally spaced points, the side walls of a unit such as a condenser, coil, resistor or other object, for main taining in suspension su'ch condenser normally in axial alignment with respect to the mounting device and in a predetermined longitudinally adjusted position without other means of support, and for permitting the condenser to be readily pressure mounted and demounted.

-As shown in Figs. 1 and 2, and in the mounting I disclosed in Fig. '4. the lower resilient grips 6 3 are each formed or shaped to provide an annular groove or corrugation 5 for the reception of the plate or pan 6 forming a part of the chassis of a radio set or other structure. By reason of this construction, the mounting device. when pressed into the opening in the plate or pan 8, will lock therewith by a resilient and yieldable grip and he retained against accidental displacement, although allowing for ready pressure removal and/or replacement by manually exerting a push or pull on the mounting device without the use of tools of any kind. Due to this arrangement of locking the mounting and plate by means of the resilient grips, the resilient gripping pressure of these members against the object will be increased or accentuated.

In utilizing my suspension mounting, preferably it is put into use by first pressing the mounting into a suitable opening of a slightly larger diameter, such as the opening in the pan 6 shown in Figs. land 2 and elsewhere, then the condenser 4 is grasped in the hand and moved into the opening in the mounting by a twisting pressure. As the condenser is initiallyadvanced into the opening, one set of the longitudinally spaced resilient but firm gripping'members first grips the condenser, or other object which is being mounted, then as the mounted object is further moved into the desired predetermined, longitudinally adjusted position, the other set of longitudinally spaced resilient but firm ripping members likewise grips the surface of the object to be mounted. At this stage a fulcrum action is set up which causes the gripping members in both sets of gripping members to impinge and resiliently but firmly grip the surface of the condenser and automatically axially align it with respect to the mounting device. Wherrthe condenser has been moved to the desired position it is there resiliently but firmly held in such longitudinal, predetermined adjusted position without any other supporting means. At the same time it is mounted in such a way as to permit it to yield under abnormal strains or stresses, either axially or longitudinally, such as might be imposed in handling or in use and further permits the ready readiustment of the longitudinal position or the replacement or removal of the condenser. However, if desired my novel suspension mounting may be applied to the condenser or other object to be mounted before it is put in its position for use.

In each of Figs. 1, 2, 4 and 6, the ends or gripping surfaces or points I of the spaced members 3, are adapted to bite into the surface or material of the member being held, while the resilient gripping members 2 in Figs. 1 and 2 and the resilient gripping members 8 of the mounting, l of Figs. 3 and 7, have ends 8 so formed as to receive and frictionally and tensionally engage the surface or casing of the member 4, so as to retain the member in adjusted position or be seated in grooves or depressions provided therein.

As disclosed in Fig. 4 the upper gripping members iii of the mounting I may also be formed to provide a relatively sharp edge or end I l adapted to bite into the material of the member to be held.

In Fig. 5 the upper and lower gripping members ii of the mounting I! are similar in contour and the ends i3 thereof are adapted to tensionally grip the member I with greater surface area than the forms shown in the preceding views.

In Figs. 8, 9 and 10 there is disclosed an alternate construction of mounting II in which the upper resilient gripping members 2 are preferthe members ably of a contour or configuration as shown in Figs. 1 to 5 inclusive, while the; lower set II and II are of similar contour except that ll are formed with a wider groove l1 than the groove ll shown in Fig. 10 and the members I! are so formed as to frictionally and tensionally engage and be retained in a plate or pan I! of greater thickness than the plate or pan 2. shown in Fig. 10. Thus by reason of this construction, a standard form of mounting may be employed and locked to the chassis pan, plate or other base even though they may vary in thickness.

The present device is preferably made of some suitable metal which may be readily treated for hardening and spring tempering so that the gripping members may have suflicient resiliency w cause them to resiliently grip the object to be mounted with a resilient but firm grip. In forming the gripping members the conformation of both. the bottom and top sets is preferably such that the object to be mounted will be gripped near the free ends of these members.

It will be appreciated that as the object is inserted in the mounting, the contact of the lower set of gripping members with the surface of the object to be retained will tilt or cant the base and the other set of gripping members about the support or base so that the upper set will more forcefully grip or bite into the surface of the object. Also, this base or support will help to retain pressure on the bottom grips and prevent their deformation.

To further prevent the unintentional removal of the condenser by a person, for example, grasping the condenser to move or lift the set in which the condenser is mounted, it may be desirable to so form the lower grips as shown in Figs. 2, 4 and 6 so that the contact edges of the grips bite or cut into the surface of the material of the condenser thus insuring against accidental removal merely by a straight manual upward pull. When it is desired to intentionally remove it, then the condenser is given a pull upwardly with considerable force concomitantly with the twist of the condenser.

To facilitate the application and holding prop erties of my suspension mounting the ends of the upper resilient grips terminate at an angle to their plane. Thus the leading edge of the grip first impinges and bites into the surface of the object being mounted, and it is desirable when mounting an object therein that it be turned as it is forced into the mounting.

When it is desired that the object or component be either inserted into or withdrawn from the mounting with equal facility, the upper and lower resilient gripping members will preferably be formed as shown in Figs. 3 and 5 so that these members will each present the same surface conformation and gripping action.

When the mounting is employed for supporting an electrical component, and the pan or base is constructed of metal, it may be advisable to suitably insulate the mounting. This can be readily accomplished by inserting insulating filler or medium between the pan and mounting wherever these two members may contact, and/or between the mounting and object to be retained.

It will be obvious that various modifications of the present device may be made, as for example by forming the end of each gripping member in accordance with the surface contour of the memher to be gripped. It may also be advisable to roughen, corrugate or kn'url as at 25, the ends of 7s the gripping members so that they may more readily grip the particular type of material forming the outer surface of the member to be mounted.

From the above disclosure it will be apparent that although the invention is disclosed as mounting a condenser, coil resistor or other electrical unit or component. it is equally well adapted for use in retaining numerous and varied objects which are to be retained in a resilient but firm position, although permitting their ready removal or replacement. It will be further apparent that the conformation of the lower gripping members is such that a curved recess is formed to receive and lock onto an edge 0! the pan,- base to support upon which-the object is to be mounted, and thereby anchor the mounting in assembled position.

I It is to be understood that although the mounting is disclosed as circular, it may be readily varied in shape to accommodate and retain ob- Jects that may be other than cylindrical.

Having thus disclosed the invention, I claim:
