Application filed March 80, 1916. Serial No. 87,71 2.

' for reproducing sounds through the medium and associated bearing:

of a record impressed on a tape or ribbon.

Sound reproducing machines now ingeneral use, utilizing cylinder, or disk records, can play but a limited time, two to four prohibiting the use of larger records.

An object of this invention is to provide an instrument, and a record therefor, which will play for an extended period of time.

Another object is the provision of an instrument having a resonance chamber underlying the record at the point where the reproducing stylus contacts with the record.

A further object is the provision of a record bearing medium comprising a rectilinear strip having a plurality of records indented on each side thereof.

With the foregoing and other objects in view, which will appear as the description progresses, the invention consists of the novel construction and arrangement of parts set forth, and illustrated in the accompanying drawings which form a part of this specification, wherein is set forth an embodiment of the invention, but it is to be understood that such changes, modifications and variations may be resorted to as come within the scope of the claims appended hereunto.

Referring to the drawing, wherein similar reference characters designate like parts-in the several views, Figure 1, is a front elevation of anembodiment of the invention:

Fig. 2, a plan: Figs. 3, and 4 are respectively, end views: Fig. 5, a central longitudinal section of the resonance box: Fig. 6, a transverse section of the resonance box: Fig. 7, a longitudinal central section of the spindle Fig. 8, ,a perspective view of the record ribbon.

Referring now more in detail to the drawings, the reference character -1 4 designates a cabinet, which may be'of any'desired design, or construction. Upon the cabinet at tone arm 24. The band has impressed,

-2- is erected which carries a sound box 3.

ed with the tone arm by means of a sliding sleeve -4 which may be moved in and out, to adjust the sound box in different positions, it being maintained in adjusted posltion by means of a pin -5, on the sleeve, which engages in notches -6- on the tone arm. A resonator -7- is erected on and extended laterally from the top of a vertical hollow column -8- which is erected onthe cabinet in proximity to the tone arm, and in such relation thereto that the needle -9- of the sound box will rest on the resonator. The resona'tor is preferably a skeleton frame 10, secured to and in communication with the interior of the column 8, and is covered with a suitable membrane, or skin 11-. As illustrated, the resonator is rectangular in cross section and inclined on its longitudinal axis at a suitable angle to the horizontal. Shafts 12 and 13- are suitably jounnaled in a frame comprising front and back plates 15 and 16-. Rotative movement is imparted to one of the shafts as 13, by any suitable means, such as a belt 17- which leads to a suitable source of motive power, usually a spring or electric motor located in the cabinet. A suitable friction device, such as a spring 18, bears on the other shaft 12 and serves the movement thereof. The

shafts

12 and 13 extend forward a suitable distance from the frame and are provided on the ends thereof, with suitable coupling devices, such as sockets 19- which have bayonet slots 20, for the reception of spindles 21. The spindles are adapted to fit in the sockets 19, and are provided at each end with a radial pin 22 adapted to be engaged in the 'slots 20. The spindles are also provided with axial depressions 23--, in each end for the reception of a pivot bearing, to be hereinafter described. The spindles are also provided, intermediate their length, with suitable means, suchas a pin 2L, for the attachment thereto of a band, ribbon or tape '-25 of suitable material, such'as celluloid, y means such as a tab, -26, secured to each end of the band and having an eye 27- adapted to be engaged over the pin The sound box is connector indented,

to steady on either or both surfaces, a plurality of resonator, resting thereon between guides -29, under a guide roll -30-- and the.

, end tab attached to a spindle which has been inserted in the socket of the accumulator shaft 13. The sound box 3 is then adjusted, by sliding it in or out of the tone arm 2, to adjust the needle 9, in the desired record groove. Compartments, or

magazines

31, and 32 are positioned respectively in front of the

sh ts

12 and 13 to accommodate the record rol As illustrated these magazines comprise rear vertical members, or, bars -33,' with upper and lower lateral arms 34-: and 35- extendingforward therefrom a distance substantially the same as the width of the record roll, Tome of these arms, as 35, a gate -36-- is hingedly conv outer ends of the spindles. It is obvious that the bars 33,

arms

34 and 35, and gates 36 face, The records run in opposite'directions nected and is adapted to be engaged with, and held in closed position, by a latch -37-, on the other 'arm., Intermediate the length of each gate, is a pivot -38-, which is ositioned in a depression -,39-, co-axially with the respective shafts. This pivot 38 is adapted to engage thebearings 23 in the may be developed,or extended, to completely inclose the record roll. When-a record has been played, the record band accumulated on a roll in the receiving 'chamber, may be removed and placed in a-suitable repository,

or it may be placed on the primary shaftand connected .up as previously described, in order to play a recprd" on the opposite suron each side, thus avoiding the necessity of rewinding a roll before it can be used again scribed, a r l extending therefrom and provided with a .55
