RADIO PANEL Filed Feb. 19, 1925. 4 Sheets-Sheet f1 Ey. y.


RADIOPANEL Application led February 19, 1925.

' This invention relates to means for mounting an apparatus, and for instrument panels for mounting instruments and methods of making the same. More particularly, this 'g invention relates to radio panels, that is socalled Wireless instrument boards or panels on which are mounted various instrumentalities used in reception or transmission by so-called wireless communication.

In the present method of mounting instruments of the nature described, it has been customary in mounting the same upon any base board or panel, irrespective of the relationship of one instrument to the other, care being merely taken to effect the wired relationship of the instruments to each other with as few parts as possible for proper mounting, to obtain the most compact arrangement of the instruments. Such arrangement is only accomplished by a cut and try or empirical method. Where this method is adopted the inductive relationship of the instruments is not always the same as in the position in which they are finally mounted because the panel did not enter into consi eration when the experimental arrangement Was made. Also as wireless communication is necessarily still in the experimental stage, repeated modification of the mounting of the instruments on the panel is only accomplished with considerable labor and eX ense.

his invention has for its object the provision of instrument panels or boards for mounting instruments, premitting of universal or experimental arrangement of parts to procure the most desirable relationship between the parts quickly, efiiciently and permanently or temporarily without introducing any unaccountable factor in the finally positioned apparatus lafter an adjustment has been attained experimently or by prearranged design.

Further, this invention has for its object the provision of a panel or instrument support and methods of mounting the same which will permit ready additions or adjustments of instruments forming the parts of a complete apparatus without resorting to the use of any tools ordinarily employed or in Serial No. 10,159.

any way affecting the appearance of the panel or board that holds the same.

My invention still further contemplates the new and novel combination of a panel hav-- ing universal attachability of the instruments and instruments mounted thereon, and of means for mounting the same.

For the attainment of these objectsand such other objects as may hereinafter appear or be pointed out, I make reference to the accompanying drawing and specifications forming a part hereof, which serve to illustrate preferred embodiments of my invention.

Fig. l is a perspective view, illustrating a cabinet including my new panel.

Fig. 2 is a side elevation of a portion of a panel and instrument mounted thereon.

Fig. 3 is a partial view in side elevation, taken from the rear of a modified form of panel.

Figs. 4 and 5 illustrate still further modified forms of my panel.

Fig. 6 is a section taken on the line 6 6 of Fig. 3.

Fig. 7 is a perspective view of an instru-v ment cabinet showing an instrument mounted thereon.

Fig. 8 is another form of panel and base board in perspective.

Fig. 9 is a plan view of another form of panel partly assembled.

Fig. l0 is a section on the line 10-10 of i Fig. 9.

Fig. 1l is a perspective view of an insulating strip.

The panel l() is formed of reticulated or oraminous member, preferably formed of insulating material, such as bakelite or other phenolic condensation product, or hard rubber, glass or other similar insulating material, though in instances as will be hereinafter described this panel may be made of electrically conductive material. This foraminous or reticulated member 10 may be in 95 the form of a grid having openings ll and walls 1Q, made by a molding process or from woven material, provided the walls are so thin as to present the maximum number possible of openings of a size to freely accommo- 2 i isoasi date the average adjusting members of in- -struments such as turning posts of variable condensers, variometers, tuning coils or any other instrument operated through the panel face and having any adjusting member.

In Fig. 2 I have illustrated a portion of a panel having square openings and have shown an instrument such as a typical variable resistance element or rheostat 14, having attached thereto screws 15, and held in position on the panel by key-hole'washers 1`6 of a size considerably lar er than the apertures of the panel and which has the narrow ortion thereof engaged under the screw ead. The adjusting element of the rheostat is shown'at 17.

In Fig. 7 a simi-lar view is shown wherein a typical variable condenser is similarly mounted and the adjusting post 18 is shown extending through one of the apertures 11, the instrument being similarly held in means of key-hole washers 16 over the screw heads 15.

It will thus be observed that for mounting any instrument on the panel 10, the attaching screws that are usually provided are preferably positioned in the places provided for them, the screw heads and Shanks are then inserted at any desired position through the panel the apertures being of a size considerably larger than screw-heads or adjusting posts, it will be comparatively simple to have all these elements, that is, the adjusting post 17 or screws protrude through thejpanel and find aligning opening for these members. Thereafter the large portion of the key-hole washer is slipped over the screw head and then slipped downwardly over the shank. By reason of the fact that the key-hole washer is larger than the aperture,.it will prevent the displacement of the instrument to which the screws are attached, and maintain the same in position. The screws are then turned suiiiciently to take up the slack,

and ti hten the same.

In i 1 and 7, I have illustrated cabinets wit my new improved form of anel, which is ready for use with any desired) type or number of instruments.

In Figs. 4 and 5 I have shown modifications of my im roved panel with the apertures of dierent ormation, in order to increase the relative Ossibility of the screws or adjusting mem rs of any instrument aligning with the holes provided in the panel.

In Fig. 3 I have illustrated another form of panel in which reinforcement or metallic elements 13 are included in the anel walls. These reinforcements or metal 1c elements serve also as shielding material or deflector of body capaci of the operators in devices of t the character herein dealt with, in away which will be readily appreciated by those skilled in the art to which this invention relates.

Fig. 6, which is a sectional view of the device such as shown in Fig. 3, shows the method of mounting the reinforced, metallic elements within the walls of the insulating panel and, in addition, shows a covering material 19, such as muslin or the like, which may be superimposed upon the outer portion of the panel 10 when the panel which has had instruments mounted thereon in the manner above described and which are desired to be maintained in permanent form, so as to hide the method of mounting of the instruments on the panel itself.

In Fig. 8, I have shown a still further modification wherein the panel is made of woven rodsor similar elements. In this view the baseboard 20, as well as the panel 10, is made of reticulated or foraminous material. The instruments are mounted in a wa similar to that shown in Figs. 2 and 7 and eld in position detachably by key-hole washers, such as have been above described. These rods may be firmly attached at the points they Contact or -frictionally engage to an extent suiiicient to permit of a slight amount of relative movement, to allow for that, slight amountof resilience necessary to position instruments or their attachin parts, where the latter are not readil capa le of aligning with the apertures of t e panel.

For purposes of illustration, I have shown a variable resistance element 21, a variable condenser'22, a variometer 23, an audio type of socket 24, a grid-leak or the like 25, in the manner in which they will a pear when viewed from the inside of the cabinet, on the baseboard and panel.

The foraminous or recticulated panel, such as I have above described, may be made of insulatingmaterial and molded in a way such as will be obvious to those skilled in the art, or may be sawed, drilled, cut or weven, particularly as in the modification as shown in Fi 8.

Further, t ou h I have described my panel as being made o insulating material for certain purposes, it may be made of metallic or conducting material, particularly where the instruments that are to be mounted have their individual parts insulated by self-contained insulating members.

Where apparatus is used in which 'the attaching members or screws have their bosses of smaller size than the apertures of the panel, I contemplate providing means to act as the equivalent of large bosses by slipping an ordinary washer on the screws or attaching member on the inner side of the panel of the screw or attaching member. It willalso be i observed that though I have described attaching screws as the means for mounting the apparatus, these may be omitted, particularly in apparatus where the adjusting or turn- 1n post also serves as the attaching means.

urther, it will be observed that the attaching screws themselves may be made to give additional adjustability of alignment with the apertures of the panel by making said screws adjustable as by an eccentric or slidable connection to the instrument.

In the modification shown in Fig. 9, 30 is a frame having notches 31 formed therein on the inner face adapted to receive insulatin strips 32 having a series of complementa notches 34 adapted to receive the strips laid crossWise to it which are similarly notched.

A grid or foraminous frame may be built by inserting strips 32 with the notched members 34 in one direction. Cross strips are then laid transversely to the irst group of strips. The complement-al notches 34 engaging each other to the medial depth of the strips so that the combined thickness of the two strips at the point of engagement equal the thickness of each strip. NVhen the grid is completed, a frame 33 corresponding in shape to the frame 30 is secured over the ends of the strips to hold the same in place.

As shown in Fig. 9, the grid may be built up completely to lill all the notches in the frame there provided, or for any special Work, portions of the strips may be omitted to accommodate various types of instruments that it may be desired to mount on the panel.

The strips 32 may be made of molded insulating material with the notches formed there in by the molding process or in which the notches 34 are cut from the same. However, I prefer to make these strips of fabric material such as canvas which is dipped into insulat-ing material and baked. The insulating material that mayT be used for this dipping process may he the Well known liquid bakelite or other similar insulating material which is applied to the fabric material, and thereafter the fabric so dipped is stamped, cut or molded into the form of strip shown in Fig. 1l to be cut into lengths for diii'erent size panels or frames to receive the strips.

In this manner, it will be observed that an instrument panel may be assembled having apertures which are adapted to receive the attaching elements of almost every kind of radio instrument so as to make the same substantially adapted to universally mount any desired kind of instrument. Further, with strips as mounted in the panel as described in Fig. 9, making it possible to add to or omit any desired number of strips, the possibilities of forming the aligning apertures for the attaching elements of instruments is further increased.

In this way, it will be observed that I have provided a device which is of particular utiiity to experimenters for quickl and elli* ciently mounting instruments to o tain best operable results With Wireless systems that are known, or for use for students to experiment empirically for best operable conditions with. instruments of the type used in the class to which this invention relates when variably positioned in reference to each other. Also new parts, additions or substitutions may be made with already existing assembl instruments without undue or any distur ance of the parts already mounted and Without any drilling operation, or in any Way modifying the existing panel or instrument board.

I claim:

1. In combination a radio anel comprising plurality of predetermined regularly arranged apertures thereon, forming the major portion of the area of the panel and of a size capable of universallyl receiving attaching members of radio instruments, attachin members disposed through such apertures and means for engaging such attaching means for retaining such instruments in position.

2. An instrument panel having predetermined regularly arranged apertures and forming the major portion of the panel and formed oversized as to form universal reception and alignment of the spaced attaching members of radio instruments.

In witness whereof, I have hereunto signed my name.
