My invention relates .to Supporting devices,

and particularly to a supporting device in the formof a plate and Cooperating parts to enable a radio receiver to be conveniently mounted in position.

An object of the inventionisto provide a supporting device which comprises a mounting plate for a radio receiver in a location where the receiver can operate properly, but be out of the way; and which-will yet enable the receiver to be easily lifted out when inspection or repair is necessary. Such a type of supporting devise is particulaly useful in automobiles and in other places where there is little space available'ior radio receivers; so that the receiver must be disposed the driver or other occupants, but where it can be kept serviceable and capable of beingat some point where it will not interfere with reachedwhenever removal is required.

In the preferred embodiments of this invention herein shown, the radio receiver can be very securely mounted and very readily taken down; and while it is engaged with its supporting device it hangs securely in place without departing from the principle ofthe invention or exceedingits scope. 3 On the drawing:

Fig. 1 shows in perspectives. supporting device and the casing of a radio receiver for which the device is provided;

Fig. 2 is a perspective view of part of said receiver showing the elements to cooperate with the mounting plate;

Figs. 3, 4 and 5 are detailed views showing modifications of portions of the mounting plate to be engaged by the receivers;

1932. Serial No. 810,852.

Fig. 6 is a side view partly in section of another form of supporting device and Fig. 7 is a detail of Fig. 6.

The same numerals identify the same parts throughout.

Referring first to Figs. 1 and 2, I show at V 1 amounting plate on which is to be securely but removably hung a radio receiver enclosed in a casing 2. This receiver is of a portable type for private automobiles and police cars;

and it can be conveniently secured on the in- 7 side of a car at the fore part thereof, 'ust behind and under the instrument board. or thispurpose I provide a number of bolts 3 and the upper and lower portion of the plate 1 has separate rows of holes 4 so that the bolts can pass through the plate and aiiix it conveniently to the inside front surface of the body of the car; as illustrated at 5 for exampie, in Fig. 6. The upper edge of the plate is notched at 6; and the upper part of the adjacent side of the casing 2 is provided at each end with a small metal plate 7 fastened to the casing and having integral tongues 8 cut from their lower ends and bent outward and downward as shown at 9. These ton es engage the notches '6 at both ends of t e plateand the down-turned ends go behind the plate 1 and grip. it snugly. At the lower edge the same side of the casing has elements in the form of strips 10 projecting below the bottom of the casing 2 and having openings 11. The plate 1 is of sufiicient height, to cause the lower edge to be below the bottom of the casing when the tongues 7 engage the notches 6 and adjacent the lower edge of the plate 1 in line with the openingsll are aper-- tures 12. The

openings

11 and 12 aline with each other at each side and the openings 12- may be threaded so that binding screws with milled heads can be passed through the openings 11 and turn in the aperture 12.

Henge to put the casing 2 in place on the mounting plate 1, it is simply moved up to the face of the plate 1 and the tongues 8 are dropped down into the notches 6, the ends of these tongues 9 going down behind the plate 1. Screws '13 are then inserted and can e tightened as desired and-easily removed. The openings 11 may be elongated laterally .ing shape. ,through these openings they receive spacing to allow for slight variations in the fit of the parts 8 into the recess 6 and the relative positions of the strips 10 and openings 12.

With this construction the radio receiver can be mounted ver securely and held fast against vibration. t can be easily taken off merely by removing the screws 13 and by lifting it above the plate 1. The radio receiver is .of course only diagrammatically shown and is provided with as many leads 14 and 15 as are necessary extending to the outside for making electrical connections with the battery, the antenna and the loud .speaker.

In Fig. 3 the plate 1 is shown as having the recesses 6 made by cuttinginto the upper edge of the plate and bending back the parts between the two cuts as shown at 16. Fig. .4 shows recesses 6 at, the very ends of the plate; and Fig. 5 shows a small recess made as in Fig. 3 by cutting the top and bending .over the upper corner.

To secure the plate the bolts 3 are provided with suitable heads and squared or otherwise polygonal portions 17 to fit the selected openigg s 4, which are of correspondhen the bolts are passed sleeves 18 which separate the plate from the nner surface of the car as shown at 5. Fig. 6 indicates diagrammatically a part of the .wall or shell of the body of the car with opemngs for the bolts 3 and the ends of the bolts are threaded to receive washers 19 and nuts 20. The openings indicated at 4 may be disposed both at the upper and lower part of the plate, so that the plate is held firmly ,at three points.

a catch havin Fi 6 shows another form of mounting for a ra '0 receiver in which the back of the receiver has elements 7 a with turned-out lower parts 8a and down-turned lower edges 9a .to engage recesses as above described in the plate 1 which is secured to the inside surface of a wall of the car as indicated at 5. The lower edge of the plate 1 may have a small projection which is turned over towards the wall 5 to form a shoulder and this projection may be provided by shaping the plate so that 1t is integral therewith, or a small angle piece may be riveted to the rear face of the plate 1 to provide this projection. At 23 is lever 25 swivel ed at 26 to the bottom ofthe casing 2. The swivel point 26 will be in front of the omt of attachment of the element 23 one'end pivoted at 24 to athe slate and the casing 2 is then swung towar s the plate 1 to carry the ledge 22 beneath the projection 21. Hence vertical movement of the casing 2 which might tend to disengage the elements 7a from the plate 1 is prevented. The end of the element 23 is thenhooked over the projection 21 and the lever 25 is pulled back so as to tighten the element 23. Thus the receiver is secured and it can be taken of! simply by swinging down the lever 25 to loosen the catch 23. The element 23 may be simply a closed link like the links in a chain.

In the foregoing description it will be seen that this supporting device is very simple but extremely practical. It is admirably ada ted to mount the receiver securely and hol it against vibration and permit the read removal of same.

ith the construction above described the casing 2 can be mounted on either the inside a or outside of the partition between the motor and the driver. The radio receiver can also be hung in this way on the back of the front seat or to the wall inside the car at either side of the rear seat as well as on the inside of a trunk carried by the car.

The screws 13 and other parts can, of course, be of any type and the plate 1 may also have studs 27 to engage the adjacent face of the receiver 2 and keep the turneddown ends 9a of the elements 7a in tight engagement with the plate 1.

Having described the invention, what is claimed is:

A supporting device for a casing comprising a plate having notches in its upper edge with transverse rows of apertures below said notches to be selectively used in combination ,with bolts to secure the plate in position, the apertures being polygonal and the bolts having correspondingly shaped portions to fit the apertures, spacing sleeves to envelop the bolts between the plate and the support to which it is attached, the casing having elements secured thereto and comprising downward extending tongues to engage the notches in the up er edge of the plate to enable the casing to be hung thereon, studs on the plate below the notches to space said casing from the plate and'keep said elements in tight engagement with the plate, and detachable means for securing the lower part of the easing to the plate adjacent the bottom edge 1 thereof.

In testimony whereof I aifix my signature.
