My invention relates to a loud speaker mounting and has e ecial reference to means for mounting a lou speaker in an automobile in whatever place is suitable. In placing radio receiving sets and loud speakers in automobiles, serious difliculties have been encountered in finding a proper method of mounting loud speakers so that they will be held in place and will not vibrate or rattle because of movement of the vehicle or vibra-. tion from the engine.

The principal object of my invention is to provide means for mounting a loud speaker in any desired place in an automobile so that it will be held securely in place and will not rattle or vibrate.

While the invention is primarily designed for automobile use, yet it is not limited to this use alone as the same method of mounting may be used on the back or underneath art of radio cabinets having no loud speakers installed therein.

In the particular embodiment of my invention selected for illustration,

Figure 1 is a side elevation of a loud speaker mounted on a panel board.

Figure 2 is a ottom plan view of a loud speaker embodying my 1nvention and showing the method 0 securing the s eaker to the element secured to a panel boa or other suitable object.

Figure 3 is a section on the line 3-3 of Figure 2, and V Figure 4 is a detail of one of the springs or lugs for securing the speaker in place.

The loud s eaker well known esign its back, secured thereto by suitable fastenings, as the rivets 6, the clip members 7, each strip with a com forming the base 5, which represents any art by which 1t is secured to the speaker, an a. tongue spaced from the s eaker back with a space between it and tiie back open at the end of the tongue. These clip members 7 are arranged in circular series with their tongues all extended in the same circumferential direction. Each tongue has a depression 7 near its free end, toward the speaker back, forming a detent.

The plate 8 has radial arms 9, one for each distance from the bear and construction, has on ound bend clip member 7, and has compound bends at the junctions of the arms '9 withthemain art of the late, which is screwedto the veicle panel oard 10 with the arms 9 s aoed out therefrom by the bends. The s alrer 5 is placed against these arms 9 an rotated until the. Cllp members 7 snap over the respective arms 9, with eacharm held snugly between the chp member ton e and the s eaker back, and between the de tent 7 and t e shoulder formed byjthe compound bend of the clip member 7. The members 7v and arms 9 are each referably three in number, so that thedescri ed engagement firmly holds the speaker 5 from movement either toward or from the board 10, or parallel thereto. The arms 9 are projected from the board 10 far enough to hold the s eaker the'required to leave its back freely open, for efiicient o eration of the speaker; and the firm holdmg prevents vibration and rattling. so apt to occur on 9. vehicle, and which is especially objectionable for an acoustic instrument because of interference with the sounds produced thereby, as well as damage to its operating parts.

While the invention has been described above in its referred form, it will be obvious that V8.1'10l1S changes and modifications may be made therein without de arting from the spirit or scope thereof an it is therefore desired that only suchlimitations may be imposed thereon as are necessitated by the prior art or specifically set forth in the appended claims.

Having thus described'my invention, what I claim as new and desirevto secure by Letters Patent, is:

1. A device to mount an instrument on an upright support comprising a series of members on the back of the instrument, spaced out therefrom withone'end of each member free, leaving an entrance space thereunder, and a series of members on the face of the support, spaced out therefrom and so arranged that each member will enter the space under a respective member on'the instrument through the entrance space thereunder, the members on the instrument being so spaced therefrom as to hold the support members snugly to the instrument back, and the sup port members being so spaced from the support as to hold the instrument with its back a required material distance from the suprt. 2. A device to mount an instrument on an u right support comprising a circular series' of members on the back of the instrument, spaced out therefrom with one end of each member free, leaving an entrance space thereunder, said members being arranged with all of said entrance spaces opening in the same circumferential direction, and a series of radially extended arms on the support, spaced 15 out therefrom and so arranged that when theinstrument is placed against said arms and rotated each arm will enter a space under a respective member on the instrument through the entrance space thereunder, the I :0 members of the instrument being so spaced therefrom as to hold said arms snugly to the instrument back, and said arms being so spaced from the support'as to hold the instrument with its back a required material as distance from the support. I

3. A device to mount an instrument on an upright support comprising clip members each formed of a compound bent strip 0 resilient material with one end part fixed to 80 the back of the instrument and the other end part spaced from said back, said other end art having a 'depressionjtoward the back, orminga detent, and said members bein I arran ed in a circular series with said en 86 parts iaving the detents all presented in the 7 same circumferential direction, and a plate fixed on the face ofthe support having radial arms and compound bends spacing said arms from the support, the arms being so an b ran d that when the instrument has its bac placed against said arms and is rotated, sail clip members will snap their detents over repective arm, the end part of the clip members having detents being so spaced from the instrument back as to hold said arms snugly to the instrument back, and the detents bein so spaced from the respective compoun bends of the clip members as to hold said arms snugly between the detents and the compound bends of the respective clip members the number and dispos tion of the arms and corresponding clip members being such that the engagement of the arms and the detents and compound bends prevent movement of the instrument in all directions parallel with the face of the support, andsaid arms being so spaced from the support as to hold the instrument with its back a required material distance from the support.
