CABINETED. PHONO'GRAPH.

Specification of Letters Patent.

Patented Sept. 19, 1916.

Application filed February 15, 1916. Serial No. 78,361.

.Monticello, in the county of Sullivan and State of New York,have invented certain new and useful Improvements in Cabineted Phonographs, of which the followingis a specification.

The invention'is an improvement in cabineted constructions for phonographs, suitable especially for embodiment in table form, the phonograph being accessible without disturbing the top. Phonograph mountings wherein this is possible are known, but they have involved .the use of swinging phonograph supports, and their horns have been built in stationarily as a part of the cabinet, as is the general practice in cabineted machines. In such constructions the manner of mounting the phonograph sup port has rendered it ill adapted to sustain the considerable strain which is imposed upon it by the weight of the motor and other parts when the support is drawn out from the casing, and, furthermore, because of the swinging mounting, it has been necessary to sacrifice the best acousticresults by an awkward arrangement of the horn, and to provide pivotal joints between the horn and the phonograph support. The purpose of this invention is to overcomethesediflicuh ties and disadvantages and to provide a construction which will be of great strength and rigidity, convenient in use, and wherein the parts will be advantageously disposed with regard both to the character of the space available and the soundingqualities of the machine.

In the accompanying drawings illustrating the preferred embodiment of the invention: Figure 1 is a longitudinal vertical sec tion; Fig. 2 is a vertical transverse section on the line 22 of Fig. 1; Fig. 3 is an end elevation; and Fig. 4 is a fragmentary plan,

the carriage being shown pulled out some what farther than'is necessary for the purpose of inserting or removing a record.

The phonograph and its horn are housed in a horizontally elongated casing 1, forming the upper part of a table, whereof 2 are the supports. The top 3 of the table, which forms the top of the casing, is fixed, not requiring to be moved in order to obtain access to the phonograph mechanism. The forward end of the casing is substantially Y carriage;

open, to constitute a sound exit, and may be occupied by a lattice screen 4. The opposite end is closed by a movable wall 5. United with this wall is a phonograph car riage 6, which preferably carries both the phonograph and the horn, and is drawn straight outward whenit is desired to in- I sert or remove a record. g

In the preferred embodiment of the invention illustrated the carriage comprises side. guide rails 7 united to the movable wall 5, and a motor board 8 mounted upon and further uniting the rails at their rear portions. The said rails are shown supported on the bottom wall of the casing, whereon they may travel easily by virtue of the provision of rollers 9, and further guided byledges 10, which project inward from the sides of the casing and include guide portions cooperating with the rails at both top and sides. i I

The phonograph mechanism, of ordinary construction, includes a motor 11 secured to and beneath the motor board, a turntable or record support 12 and a swinging reproducer arm 13 carrying a sound box 14; The side rails 7 project for a substantial distance beyond the motor board and as shown are extended almost to the sound exit 4. The

horn 15 extends straight forward in the space between the side rails, with its forward end in proximity to the sound exit, as shown. in Fig. 1, and is preferably united rigidly at its rear end to the underside of the forward portion of the motor board, in communication with the hollow reproducer arm, the horn thus being movable with the The bottom wall of the horn is shown substantially horizontal, .while its upper wall inclines upward above the plane of the motor board and its side walls flare outward, at approximately equal angles, to or beyond the forward portions of the side rails, the horn as thus constructed being adapted with relation to the phonograph mechanism for accommodation in a chamber -of comparative shallowness, yet being of a shown mounted on the end of a lever 20,

which is pivotally secured at 17 tothe motor board and provided with a rubber covered stud 18 to contact with the periphery of the turntable. The arrangement is such that when the lever is moved in one direction, as permitted by a slotted opening 19 in the wall 5, the brake stud is carried away from the turntable, so that the latter may revolve, while when moved in the opposite direction the stud is brought to bear against the periphery, being held there by the action of the record support itself. In addition, the pivot 17 may be made with sufiicient friction to hold the lever either on or off, or special means may be provided for the purpose.

-When the carriage is drawn outward the length and rigidity of the guide-rails 7, half of which, more or less, remain within the guides, together with the counterbalancing elfect of the horn, the greatest mass of which is located toward the end of its lever arm, insure firm support to the projecting portion of the carriage, weighted by the motor and associated parts. When the phonograph is not in use the carriage is pushed all the way in, this being also the usual position when a record is being played, but if desired the sound may be varied by leaving the carriage partly out, thus increasing the distance between the mouth of the horn and the sound exit.

What I claim as new is:

1. A cabineted phonograph comprising a horizontally elongated casing having a sound exit at one end, a carriage guided for rectilinear movement in said casing and withdrawable at the opposite end thereof, the said carriage comprising elongated side guide rails whereby it is supported when in projecting relation, and a phonograph mechanism support united to said side rails at the rear portions thereof, a phonograph mechanism carried by said support, and a horn movable with the carriage, said horn having its rear end in fixed connection with said support and thence extending straight forward between the side rails with its forward end normally in proximity to the sound exit.

2. A cabineted phonograph comprising a horizontally elongated casing having a sound exit at one end,-a carriage guided for rectilinear movement in said casing and withdrawable at the opposite end thereof, a phonograph mechanism mounted on said carriage, and a horn also carried thereby and projecting straight forward between the side guides of the carriage with its mouth normally in proximity to the sound exit.
