Application filed November 12, 1925. Serial No. 68,737.

This invehtion relates to an amplifying device for use with radio receiving sets,

known-as loud speakers. The object of this invention isto provide an improved device of this nature, articularly applicable to the cone-type loud speaker. I

The features of the invention hereinvolved have to do more especially with the method or means provided for supporting) unit, which latter may e of the parts are concerned, and by reason of the .novel means provided many advantages are obtained not heretofore possible with the usual mounting means and arrangement.

;With this object in view, I have provided a mounting device which is provided with a base, adapting it tobe placed upon a table, etc., and two vertical supports attached at opposite sides of the base. At the top and carried by these vertical supports is a circular member to which a. cone-shaped vibratory member is attached, this cone-shaped member being connected to and operated by a loud speaker unit in the usual manner. The construction and operation of this coneshaped member and loud speaker unit does not, per se, form a part of m invention,

which has'to do-with the metho and means provided for supporting the same in a horizontal position instead of in the usual vertical position with a support at one edge only.

Among the advantages found by mpuntmg the cone and its operating unit in a horizontal position is that the same is more generally non-directional in sending out the sound waves. Whether these waves are thus projected as horizontal waves or not, I have not determined, but I have found an improved quality of the tone produced when my arrangement is used over that produced by the usual vertical mounting of the cone.

Furthermore, with my arrangement, the device may, be made very ornamental 1n appearance which is a desirable feature in the present evelopment of devices of this na-.

ture.

' On account of the double su port for the cone, greater rigidity is secur and the device is very substantial in construction. This makes itpos'sible to readily adapt the loud speaker for use as the base element for a table lamp, which may bereadily attached thereto without interfering with the operation of the loud speaker unit.

In the drawings accompanying this applithe loud' cation, I have shown one embodiment of my invention and in the description of the sevany suitable size or shape and arrangedto rest upon a table or other article of furniture, as desired. Two vertical supports, 2

and 3, are attached at opposite sides of the base 1. The supports may be of suitable ornamental design, as desired.

A circular member 4 is mounted in a horizontal position on top of the two vertical supports 2 and 3. This circular member is relatively rigid in construction. A coneshaped vibratory member 5" is mounted at its edge upon the circular member 4 and is connected with a loud speaker unit, indicated at 6, in the usual manner. That is, the cone-shaped vibratory member and loud s eaker unit may be of the usual construction, but with the diflerence that the cone is mounted in a. horizontal position-and carried u on two vertlcal supports at its opposite e ges.

One of the vertical supports is provided with a longitudinal opening extending therethrough, through which opening the wire connections to the loud speaker unit 6 may be led. Suitable channels arealso provided in the base 1 forbringing these wire leads to the outer edge of the base for connection to the receiving set, as indicated In order to provide a more substantial construction, a metal tube '8 may be positioned in the longitudinal opening in'the vertical support, its ends extending through ahy desired design, at the upper end of the support 2, the wires for the lamp being brought through the vertical support 2 in a similar manner.

It will be seen that by providing the horizontal mounting of the loud speaker unit and cone and two supports at opposite sides it is possible to combine the loud speaker combination, a base, vertical supports at tached to opposite sides of said base, a circular member carried in a horizontal position by said vertical supports, and a coneshaped vibrato member supported horizontally by sa-i circular member adapted forconnection with a loud speaker unit.

2. In a device of the class described, in combination, a base, vertical sup rts at tached to opposite sides of said ase, one of said supports being provided with a longitudinal opening therethrough, a circular member carried in a horizontal position by said vertical supports, and a cone-shapedv1- bratory member supported horizontally by said circular member adapted for connection with a loud speaker unit;

3. In a device of the class described, in combination, a base, vertical supports each provided with a longitudinal opening therethrough and attached to opposite sides of said base, a circular member carried in a horizontal position by. said vertical supports, and a cone-shaped vibratory member supported horizontally by said circular member adapted for connection with a loud" her and provided wit fastening means at each end securing-said members together,

and a cone-shaped vibratory member carried in ahorizontal position by said circular member and adapted for connection with a loud speaker unit.

5. In a device of the class described, in combination, a base, vertical supports attached at opposite sides of said base, and a cone-sha ed vibratory member adapted for connection with a loud speaker unit and supported at opposite sides thereof ina horizontal position b said vertical supports.

Signed at New ork, in the count of New York and State of New York this 10 day of Nov. A. D. 1925.
