IPI-IONUG-RAEH CABINET.

Application filed June 6,

This invention relates in general to phonograph cabinets, and more particularly to the projection and amplification of sound reproduced therein, one object of the invention being to provide an improved construction for projecting the sound upwardly and outwardly above the motor and tone arm supporting board or partition of the cabinet, and improve the projecting and amplifying of the sound and the quality of the tone.

Another object of the invent-ion is to provide a cabinet having; a horn-like recess above the motor supporting partition, :1 portion of the walls of said recess being formed by said motor supporting partition and the remainder of said walls being formed by a structure having; a configuration similar to 1 half horn formed. by dividing a horn on its longitudinal axis mounted on or forming a continuation of said motor board, means being provided for admitting the sound from the tone arm of the instrument into the inner end of said recess, whereby the said horn-like recess amplifies and projects the sound outwardly above said motor board.

Other objects of the invention are to provide a construction whereby the sound from the tone arm is divided, a portion of it being projected upwardly over the motor board and a portion being projected downwardly and outwardly beneath the said motor board or partition; and to provide such a con struction wherein horn-like recesses are provided. both above and below said motor board so that the two recesses serve in effect as one large horn with the reproducingmechanism in the center thereof.

Further objects of the invention are to provide a phonograph cabinet having; a movable cover mounted above the motor board, and adapted in one position to enclose the reproducing mechanism and in another position to cooperate with the tone arm and serve as a horn forprojecting the sound; to provide a cabinet having a horn comprising a throat portion connected at one end to the tone arm and opening at the other end upwardly through the motor board, and another or bell portion comprising substantially a half horn connected at its small end to said throat portion and cooperating with said motor board to form a horn-like recess above the motor board to project the sound from said tone arm; to provide a cabinet having a movable cover of a configuration similar to a half born formed by dividing a 19531. Serial No. 475,266.

horn on its longitudinal axis, said cover being mounted on said motor board and in one position forming a continuation of the same to form a horn-like recess, the said cover in another position serving to enclose the reproducing mechanism; and to obtain other results and advantages as will be brought out by the following description.

Referring to t 1e accompanying drawings, in which like numerals of reference indicate the same parts throughout the several views,

Figure 11 is a front elevation of the construction shown in Figure 10.

In the embodiment of my invention shown on the drawings, the reference character A designates the body oortion of the cabinet and the reference claracter B the motor board or supporting partition for the motor desired manner as indicated at 10.

throat pro ects downwardly beneath the par- C which is diagrammatically illustrated. Above the partition B the cabinet is formed with a hollow substantially rectangular e2:- tension D which is preferably built into the cabinet A the said extension being formed at the front thereof with an opening E in which is pirotally mounted on horizontal pivots 1 the swinging cover 2. The cover 2 has a configuration similar to a half horn which would be formed by dividing a horn on its longitudinal axis, the large end or mouth 3 of the cover being substantially semi-circular in shape and of a diameter slightly greater than that of the opening E in the extension D. The opening E in the extension D is semi-circular and the cover 2 is adapted to swing about the horizontal pivots 1 so that at one position, as shown in Figure 1, the front end or mouth 3 of the horn like cover 2 rests upon the partition 13 while the small or throat end 4rthereof is positioned adjacent the top of the opening E. hen in this position the cover 2 cooperates with the XtQllSlOll D to enclose the turntable 5 and tone arm 6, the cover being formed at its sides with an extension 7 which extends around the throat end 4- of the cover so as to close the opening E when the cover is in closed position, as shown in Figure 1. In the other position as the cover 2 swings about the pivots 1 it moves into the extension D and the sides and throat end a thereof rest upon the partition B, as shown in Figure 2.

A throat 8, which can be conveniently formed of cast metal, is mounted on the partition B and is connected at one end 9 there of with the tone arm 6, the tone arm being swiveled over the end 9 of the throat in any The tition B and the end 10 thereof is curved upwardly and opens through the partition 13, the throat increasing in size from tne end 9 thereof to the end 10. lVhen the cover 2 is swung into the extension D of the cabinet the throat end 4: thereof rests upon the edges of the end 10 of the throat S, as shown in Figures 2 and 3, so that the walls of the cover 2 form a continuation of the throat. It will thus be seen that with the side edges ot the cover 2 resting on the partition B, as shown in Figures and a horn-like recess is formed above the partition B, the said parti tion forming a portion of the walls of the said horn-lihe recess and the cover 2 forming the other portion of the walls in substantial continuation of the partition 13. The sound issuing from the tone arm (5 is thus directed through the threat 8 upwardly into the hornlike recess and is amplified and projected outwardly by the cover 2 and partition B which form in eii'ect a horn.

The pivots 1 may be of any desired construction, and for the purpose of illustration, in Figure 3 I have shown the sides of the cover formed with studs 11. which rotate in bearing sockets 12 mounted in the sides of the extension D.

In Figures 6 and 7 I have shown a modi fied form of my invention in which the sound from the tone arm is divided, a portion of it being projected upwardly over the partition 13 and the other portion thereof being projected downwardly beneath the partition B. In this form of the invention the hornlike recess above the partition B is formed by the said partition and a member 13 of a configuration similar to a half horn, an additional swinging cover 1-1 which operates similarly to the cover 1, being provided for en closing the turntable 5 and tone arm 6. In Figure 6 the cover is shown in a closed position by solid lines and in an open position by dotted lines. The throat 15 in this form of my invention has one end thereof connected to the tone arm 6, as at 16, the other end of the throat being bifurcated, the arm 17 thereof projecting upwardly through the partition B and the arm 18 thereof being connected to a horn 19 arranged below the partition B and opening through the front of the cabinet, as indicated at 20, in the usual manner. With this construction the sound from the tone arm passes through the throat 15 and is divided so that a portion thereot is projected through the l10111l1l B recess formed by the member 13 and the partition 3 and the other portion thereof is projected through the horn 19.

In both of the constructions shown in Figures 1-5 inclusive and Figures 6 and 7, the sound being projected over the tone arm and turntable 5 tends to reduce the surface noise incident to the operation of the needle upon the record, and the projection and amplification of the sound is greatly improved and the quality of the tone enhanced. In the constructions shown in l igurcs 3 and 7 the reproducing mechanism is arr ia'ed between two horns so as to more thoroughly eliminate the surface noises from they projected sound. In this construction also the volume of sound is greatly increased due to the separate amplification of the sound through two horns. The construction shown in Figures 15 inclusive also has the advantages that the horn is located abore the reproducing mechanism so that more space is available for the storage of records, if dcsired.

In Figures 8 and 9 I have shown a construction substantially indentical with that shown in Figures 6 and 7 except that the partition B serves as a portion of the walls of both the upper horn and the lower horn. The lower horn 21 is shown as substantially rectangular in crosssection, see Figure 9, the upper wall 22 thereof being directed against the underside of the partition B, as shown HID in Figure 8. It will thus be seen that the turntable and tone arm 6 are mounted substantially in the center of a large horn which is formed by the walls of the upper horn 13 and the lower horn 21, the side walls of the said arms being substantially a continuation of each other with the partition B interposed between them.

Figures 10 and 11 illustrate another modification of my invention in which the cover is pivotally mounted at 24c similarly to the cover 2 and is formed with a transverse partition which terminates in a fiat portion 26 adapted to engage the upturned end 27 of the tone arm 28, when the cover is thrown into an open position as shown by solid lines in Figure 10. The flat portion 26 is formed with an. opening 29 which registers with the end of the tone arm 28, and it will be seen that the sound issuing from the tone arm will pass through the opening 29 through the horn-like passage formed by the walls of the cover 23 and the transverse partition 25. The tone arm is preferably swivelcd as at 3 in axial alinement with the opening 29 so that the end of the tone arni always registers with the said opening in all positions of the tone arm. The cover 23 thus serves as a horn, and after the sound is projected be yond the partition the partition B cooperates with the cover 23 as a portion of the walls of the horn to further project and amplify the sound.

While I have shown and described several possible embodiments of my invention, it will be understood that this is for the purpose of illustrating the principles thereof only, and that many modifications and changes can be made in the detail construction of my invention without departing from the spirit or scope thereof. Therefore, I do not desire to be understood as limiting myself except as required by the following claims when construed in the light of the prior art.

Having thus described the invention, what I claim is:

1. In a phonograph cabinet, the combination with a body portion providing a chamber and means for mounting sound reproducing i'nechanism in said chamber, of a movable member which in one position closes said chamber and in another position cooperates with it to form an outwardlyopening horn-like recess, and means for discharging sound from the sound reproducing mechanism through said horn-like recess.

2. In a phonograph cabinet, the combination with a body portion having a partition fori'ning a wall of a chamber and adapted to support sound reproducing mechanism in said chamber, of a movable member which in one position closes said chamber and in another position cooperates with said partition to form an outwardly opening hornlike recess, and means for discharging sound from the sound reproducing mechanism through said horn-like recess.

3. In a phonograph cabinet, the combination of an extension and a partition form ing a chamber for sound reproducing mechanism, a movable member cooperating with said extension and in one position closing said chamber and in another position forming an outwardly opening horn-like recess, and means for discharging sound from the sound reproducing mechanism through said horn-like recess.
