Fig. 6 is a detail sectional view of said device, taken en line 6 of Fig. 5.

Referring in detail to the drawing. avehicle, here shown as a motor vehicle 10, has associated therewith a radio apparatus housed in the cabinet 12. The latter may be conveniently and reliably mounted for operation by the operator of the motor vehicle in the dashboard 18 of said motor vehicle, in a neat and ornam ntal relation. However, it is to be understooiii that the invention may be applied in connection with any type of radio set. or with various; kinds of apparatus and mountings that may advantageously embody the im 'irovements herein disclosed.

The cabinet casing 16 for the receiving set extends behind the dashboard 18 through an opening 20 therein, said opening being closed by a panel 22 forming the front of the cabi: net. 1.2. the panel 22 having edge portions or flanges \vhich seal the space between said casing and opening 20 and which seat against the outer edge surfaces of the opening 20-, this arrangement, by reason of the int-liuationot' the dash board 18. permitting the radio set 12 to be firi'nlysupported on the dashboard 18. The usual operating knobs 26 and indicator dials 28 are mounted on the panel 22. A cable 30 extending forward through a front wall 32 of the vehicle may have associated therewith suitable means to connect the receiving set to suitable sources of power for its proper operation. A conductor 34 may connect the receiving set to an antenna (not shown). Said antenna may be of any desired type, as, for instance, the arrangements shown and described in my application, Serial No. 224,159, filed October 5, 1927. The cable 30 and the conductor 34 may be connected to the receiving set in any suitable manner. If desired, the connection may be made permanent; preferably the connection will be made by multiple contact cap and plug members.

The cabinetcasing 16 is mounted for sliding movementthrough the opening 20 of the dashboard 18. the latter being provided with a pair of spaced angle brackets 36. secured by means of the bracket legs 38 to the inner face 40 of the dashboard 18, the set being positioned between said brackets. Each bracket 36 has a slot 42 extending rearwardly of the dashboard 20 in the upper portion of the bracket rib 46, the central axis of said slot being substa ntially perpendicular to the plane of the dashboard.

On the rear face 48 of the casing 16 adjacent side edges of said casing are mounted a pair of carrier arms 50, secured to said face Opposi'ely extending carrier arms or trunnion pins 553, projecting laterally from arms 50, are received in the slots 42, openings 54 formed in the upper edge 44 of brackets 36, and communicating with said slots, affording means for removably mounting said pins in said slots. Said pins and slots are so disposed as to maintain proper alinement of the casing 16 with the dashboard opening 20. Said slots 42 slope downwardly away from the dashboard 20, pin receiving depressions or recesses 56 being provided at the rear ends of said slots for a purpose hereinafter appearing.

To assemble the radio set 12 with the dashboard 18, the pins 53 of the carrier arms are first engaged in the slots 42 by passing them through the openings 54, after which the receiving set will be positioned with its panel board 22 facing downward, as shown in dot and dash lines in Fig. 3. The entire set is then pulled forward, with the panel 22 clearing the lower edge of dashboard 18, the pins 53 riding in the slots 42. When the panel 22 has completely passed the dashboard, the entire set is swung upwardly with pins 53 as pivots, into the position shown by the dash lines in Fig. 3. These movements are possible since the opening 20 is cut into dashboard 18 so as to open downwardly, the body of the casing 16 entering said opening, after which the pins 53- are moved down the incline of the slots 42 until the panel board 22 closes the opening 20. In this position, the dashboard forms an abutment for the panel board 22, preventing the set from swinging about pins 53, the latter being then positioned in the recesses 56 which thus assists in efi'ectively retaining the set in its mounted position. The movements detailed above may be reversed and the set may be brought into either position shown in dash lines or dot and dash lines. Thus, the move ments of the radio set from its mounted position provide accessibility to the interior of the radio set for inspection, repair or renewal of radio tubes and accessibility to the space in back of the dashboard in case of needed attention to dashboard instruments or other apparatus, without completely removing the radio set from its supporting means, i. e with the radio set still retained by its su porting means. Or, the radio set may be readily completely detached from its supporting means.

To prevent unauthorized removal of the set and to fasten the set positively in position on the dashboard, a securing means or locking device 58 is provided. Said locking device is preferably positioned at the upper part of the cabinet and includes a casing 60, secured on the rear side of the panel board 22, a properly formed cutout 62 in the dashboard above the opening 20 being adapted to receive the casing 60, so that it is properly positioned relative to a strike 64 mounted on said dashboard. The casing 60 may be made of any suitable material, preferably .metallic cover plate 66, which may be spotwelded to, the panel board 22. The casing a rotary movement.

may be formed with flanges 68 for securing means to said plate 66. .The casing 60' is further provided with an 0 ening '70 through an end wall 72 thereoi through which a bolt 74 is movable to engage the strike 64. Preferably the bolt 74 has a shank 76 slidable on the wall 78 of the casing op-- osite the plate 66, said wall having guide ugs 80 to retain the shank 76.for slidable movement therebetween.

To actuate the bolt 74,-a tumbler lock 82 of any particular construction may be. provided and may have a barrel 84 threaded into an annular flange 85 struck out of the plate 66 and retained thereagainstby a locknut 87. Within said barrel are mounted the operating elements of said lock, the face 86 of said barrel being provided with suitable key receiving means 88 by means of which a pin90, having a crank arm 92 secured thereto and to the rotary parts of said lock, may be given The crank arm 92 is mounted for rotation in a plane substantially parallel to the plane of the shank 76, and has a projecting crank pin 94 so mounted-as to be received in a slot 96 transverse the shank 76. Since the pin '94 is mounted on crank arm 92 eccentrically withrelation to the pin 90, when rotary movement is imparted to the pin 90, therpin 94will reciprocate shank 76 longitudinally of the casing 60. It will now be apparent that when the bolt 74 is moved to engage the strike 64, the receiving set cannot be moved relative to the dashboard, and

is consequently effectively retained in proper-- ly mounted, elevated position.

While the invention hasthus far been described in connection with its application to aportable radio apparatus for auto vehicles,

' like. I

' To provide the locking device 58 with au-.

it will be'understood that the cabinet construction and its mounting may be equally employed-or adapted for housing other apparatus or implements, such as tools for the vehicle and the like. The cabinet in that instance, while arranged in -relationto the dashboard of the vehicle in the manner above 5 described, will have a particular desired construction so as to serve as a. tool chest or the tomatic and semi-automatic circuits for switching the circuit or circuits of the receiving setto disconnect the latter from circuit when it is desired to remove the set from its mounting, or to connect or disconnect the receiving set, at the option of the operator, when the set is 'lockedin place, switch means 98 is provided, preferably within the lock casing 60, and controlled by the arm 100, which may be actuated by the shank 76. The

1 arm 100 may be mounted for pivotal movement on a shaft 102 carried'transverse the easing60, so that the free end of said arm barely clears the .upper surface of the shank 7 6 and is engaged between the nubs 104 and 106, so as to be swung through a predetermined angle when the bolt 74 is projected or retracted.-

The arm 100 is formed at its pivoted end with a finger 108 having secured thereto aspring maybe secured to the rear face of the plate 66 in any suitable manner to position the termi- .nal 112- relative to the end of the contact 1 spring 110, the terminal 112 being connected by any suitable means (notzshown) to the receiving set;- When the bolt 74 is fully re-v tracted to release the set for removalfrom the dash board, the nub 104 will pass and release the end of the arm .100, whereupon the spring 116, coiled around the shaft 102 and having its ends secured respectively-to'the finger 108 on the arm 100 and to a securing means 118, which functions as one terminal of the switch and is located on the block 114, will throw said arm in counterclockwise diretion so that the circuit will be broken. The spring 116,'while .normally separating the use contact spring 110 and the terminal 112, re-

tains the arm 100 in operative position for proper action with the nubs 104 and 106, when the bolt 7 4 is again moved from its retracted position, the sprin 116 being of such elas ticity that the arm T00 will readily respond to motion when engaged by said nubs. i

If the bolt74-isfully projected, the nub104 easily passes the end of the arm 100 against the resistance of the spring 116, finally abutting the stop or lip 120 formed by the opening 70 in the casing 60, the arm 100 being then engaged between the nubs 104 and 106,

and the circuit maintained broken until further aetuation' of the bolt 74 6 Thus, a full projection or a full retraction of the bolt 74 disconnects the radio set circuit when lie-desires to remove the set from its mounted position for inspection or reair.

It will be understood that a plurality of contact springs may be provided to take an A...

Also, the operator is enabled toautocare. of a plurality of circuits, and to be actuated as a unit by the arm 100. Where but one circuit is to be controlled, the arm 100 and-the finger 108 may be of metal in one piece. the casing thereby providing a terminal for the circuit. Due to the sensitivity of the arm 110, the nubs 104, 106, may pass and repass the end of the arm 100, actuating the switch elements in the desired manner with ease and simplicity.

It will thus be seen that there is provided a device in which the several objects of this invention are achieved, and which is well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention, and as-various changes might be made in the embodiment above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawing is to be interpreted as illustrative and not in a limiting sense;
