In Fig. 2, this top has been phonograph which is so combined with a moved so that it is slid downwardly behind table, for example a library table, that the the phonograph mechanism proper with 15 table may be used for its ordinary purposes only the upper portion and'a portion of either while the phonograph is playing or the projecting part 5 showing. 1 at other times; to provide a phonograph so Figs. 3 and 41 show the position of the combined with a library table that the parts various parts of the phonograph mechanism are readily accessible either for operating within the compartment 2.

The

Q It is to be noted that the first form of the horn portion 17 is of substantially U-shape' 1 invention illustrated in the drawings is and tapers gradually from the point where shown in Figs. 1 to 5, inclusive, and that it joins the stationary portion 22 of the the second and third modifications, which sound arm to its other end located between merely illustrate other possible forms and the bottom curved portion 23 of this U- not all possible forms, will, in assembled shaped horn and the upper portion of its enlarged end. the inner edges horn and is joined thereto by a sliding tight fit joint; The edges 25 may be conveniently lined with felt so as to insure a tight joint between such edges and the adjacent portions of the member 17. A deflecting wall 26 extends from the upper edge of the openi-ng ly downwardly. The sound; waves, upon striking this deflecting wall, are projected outwardly through the other portion 18 of the horn.- 4

It will therefore be seen that this particular arrangement of the removable panel makes it-convenient in assembling and also in repairing the machine as the removable panel, the sound arm, and the portion 17 of the horn may be completely removed from. the machine.

When the machine is in use, the top 4 of the compartment 2 may'be raised and the record placed upon the disk 9. Thereafter the machine may play eitherwith the top 4 open as shown in Fig. 2 or with the top closed as shown in Fig. 1, the sound in either case issuing outwardly through the slatted opening at the front lower portion ofthe table. The volume of the sound-may, of course, be regulated by the adjustment of the slats 19. 4 and the handle 12 folded flat against the side of the machine or else completely removed, thereby giving the eflect of an ordi-' nary library table which may be of course used in its usual capacity.

In the modified forms shown in Figs. 6, and 7 the removable panel construction is employed in the same manner as in Figs. 1 to 5', inclusive. I

Fig. 6 shows a form of the device in which the phonograph casing 27 is supported by means of flanges'28 and 29 upon slides 30 and 31, such slides or flanges being provided with rollers so as to minimize the friction. This casing 27 is adapted to slide into the compartment 32 which last compartment corresponds to compartment 2 inthe first form of the invention. The casing 27 carries the entire phonograph mechanism and is provided in its outer wall with a series of adjustable slats 34.

In-.orde'r to insure equal movement of the device when it is drawn outwardly, two pairs of links 35, 36 and 37, 38 are provided with the outer link in each pair attached to the rear portion of the casing 27. The rear end of the links 36- and 37 are rigidly attached to a shaft 39 mounted in the rear portion of the table. When eitherof the links are moved due to the motion of the upper or lower portion of the casing 27, the other pair of links is simultaneously moved by the motion communicated thereto by the shaft- 39, thereby insuring equal inwardly of the portion 17 and diagonal-,

The top 4 'is closed as in'F1g..

movement of the upper and lower portion of the casing 27. These links may be so arranged that when the phonograph casing 27 is in its extreme outward position the links will lock this casing against 'acc1- dental inward motion by their toggle joint action. In order to cause these links to pass over dead center, an'arm 40 is rigidly attache-d adjacent the lower portion of the shaft 29 and is connected by means of a rod 41 with a handle.42 extending outwardly at the lower front portion of the table. The rod 41 may conveniently be guided through an eyelet 43 secured to the lower portion of the table and may be of such length that when the casing 27 is fully retracted the handle 42 is positioned beneath the forward edge of the table. The winding crank may extend at any desired point from the casing and has been omitted for the sake of clearness.

In this modification, the phonograph is pulled outwardly and a record placed thereon, and the machine started. It may be allowed to play while in the extended position or while in the retracted position.

Fig. 7 shows a further modification of the invention in which the casing 44 of the phonograph is hingedly mounted at 45'adjacent the lower portion 46 of the table. It

is adapted to rock inwardly into the compartment 47 and occupy the dotted line position shown in this figure. In orderto allow' adequate clearance for the casing 44, when it is being swung inwardly or outwardly, the flap 48 is hinged at 49 so that it may extend downwardly in its normal position or horizontally as shown in full lines. When in the horizontal position, it is retained by means of a catch 50, such catch being released by means of a cam 51 operated by a handle extending outwardly from the end of the table. A link 52 is positioned-upon each side of thecasing 44 and is pivotally secured at 53 to the table. The free end of the link 52 is-provided with an elongated slot 54 which cooperates with a pin 55 cured to the casing 44., It will'thus be seen line position when the casing 44 is swung inwardly, and swings outwardly to the full line position when the casing 44is swung that the link swings inwardly to the dotted used as-desired andthat the library table may also be used in its normal capacity. It will also be seen that all of the parts of the phonograph are readily accessibleand may be easily assembled during its manufacture.

- movable from the panel Great compactness is secured by this invention without a sacrifice of desirable acoustic properties.

I claim: v

1. A phonograph including the combination with a supporting frame, of means secured to the frame for rotating a record, a whollyremovable panel separately secured to the frame, a sound arm and reproducer associated with said removable panel and removable therewith, and an amplifying horn composed of two sections,'one of said sections being permanently associated with the frame and the other being associated with said repanel and adapted to register with the first mentioned section when the panel is in place upon the frame.

2. A phonograph comprising a main cabinet, a fixed horn portion disposed within the cabinet, means above said horn portion for rotating a record, a removable panel disposed totherear of said record rotating means and normally supported Within the cabinet, and a second horn portion supported and provided above the panel with a sound arm and reproducer in communication therewith, said panel, sound arm,

shelf therein,

reproducer, and horn portion being slidably removable as a unit from said cabinet.

3. A phonograph comprising the combination with a box-like cabinet, a horizontal and means supported from said shelf for rotating a record, of a Wholly removable panel at the rear of said shelf and constituting'an extension thereof, an amplifying horn portion permanently associated with the cabinet beneath said shelf, and a second amplifying horn portion of substantially a U-shaped contour associated With the removable panel and provided with an opening registering with said first mentioned horn portion, said second horn portion being of such a character that it can be Withdrawn with the panel in a sliding movement through the opening left by said panel Without disturbing the means for rotating the record.

In testimony whereof I afiix my signature the presence of two Witnesses.
