Specification of Letters Patent.

Patented May 1, 1917.

Application filed July 31, 1914. Serial No. 854,309.

1 skilled in the art to which it appertains to make and use the same.

This invention relates to portable cabinet gramophones and refers more particularly to an improved amplifying device for use 5 with instruments of that description, which folded int amplifying device is of the type which is so constructed as to ena re itto be collapsed into a small comp s so that the machine is easily portabl since the amplifier can be a small space when not in use .en the amplifier is in the playing pos' ion it is of relatively large size thus giv- '.g the reproduction a full and clear tone instead of the small muffled and pinched tone 5 usnally observed with small cabinet machines.

The present invention refers to an improved construction of amplifier of the before mentioned description comprising a tapering board provided with two side walls and another tapering board hinged with respect to the first board and also provided with two side walls adapted when the amplifier is opened or collapsed to slide with re- 5 spect to the first mentioned side walls, with or without a hinged extension flap at the end of one of the main boards, such flap being preferably provided with a fixed or pivotally attached secondary flap or flaps.

In the general way of carrying out my invention I provide a small case at the lower portion of which islocated the motor, in the ordinary way. The sound box, and the tone arm, are carried by suitable means in the 4,5 correct position and the sound conduit is carried toward the back of the cabinet and opens suitably into the amplifying device, which forms the principal feature of the present invention. This device comprises a 0 lower preferably fixed portion which is tapered and where fixed may be arranged horizontally or at any desired angle this lower portion being provided with two upwardly extending side walls. Mounted in hinged relation to this first portion is the upper portion which is also tapered and which is provided with downwardly extending side portions or walls adapted to slide with respect to the fixed portion previously referred to. The upper portion of the device may have pivotally, slidably or otherwise attached thereto a secondary flap or flaps which may be turned into any suitable position according to requirements.

In one particular way of constructing a portable cabinet machine according to my invention, I arrange the motor and working parts as previously described and in such a way that the sound conduit is continued into an elbow or the like containing by preference a reflector adapted to reflect the sound waves into the amplifier. This amplifier consists of (1) a lower fixed inwardly tapering or outwardly flaring shelf or board located above the tone arm, having two fixed vertical walls and (2) a movable upper part or cover of suitable shape which is hinged and comes above the vertical walls and is provided with downwardly extending fixed flaps or walls which are somewhat triangular in shape and are parallel with the vertical walls previously mentioned.

The portion of the cover carrying the downwardly extending walls is cut out in tapering form and hinged at the back in such a way that by turning it upon the hinges the amplifier is opened more or less while retainin its rectangular form in cross section, the side walls fitting closely by sliding with respect to one another. In place of the tapering portion of the cover turning up, the cover itself, that is the whole top of the cabinet may turn up, the hinge and the downwardly extending walls being suitably located for this purpose.

At the front edges of the cover I provide a hinged flap which may form a portion of the front of the cabinet when closed, forming the door of the cabinet or it may lie against the same. The hinged flap may be provided with secondary hinged or sliding which shows various methods of constructing the portable cabinet gramophone, according to my invention.

Figure 1 is a sectional side elevation of the machine with the parts in the closed position;

Fig. 2 is a similar view to Fig. 1 with the parts in the open position;

Fig. 2 is a detail view in perspective showing how the flap f is held in an elevated position when opened.

Fig. 3 is a front elevation of Fig. '2. Fig. 4 is a plan of Fig. 3. Fig. 5 is a perspective view of the machine on a smaller scale.

Fig. 6 is a similar view to Fig. 1, of a modified form of the machine.

Fig. 7 shows plan of a detail;

Fig. 8 shows another detail.

The same letters of reference are employed to denote the same parts in all the views.

Referring to the forms of the device shown in Figs. 1 to 5 the amplifier comprises a lower fixed inwardly tapering outwardly flaring board a. This bottom board a; is furnished with two upwardly extending side walls I), b. c is an upper tapering or flaring board hinged at (Z to the top of so the cabinet and provided with downwardly extending side walls 6 at such distances apart as to be adapted to slide on the outside of the upwardly extending side walls I). f is an extension flap which is hinged at g to the forward end of the board 0. This flap 7 is so arranged that it can be turned down so as to come in front of the machine as shown at Fig. 1, or so that it can be turned up and retained in the upward position as shown in Figs. 2 and 2 by means of fastenings or catches such as indicated at h Fig. 2. k is are side flaps connected to the extension flap f. The flaps is spring inward slightly so that when the extension flap f is raised as indicated in Fig. 2, the inner edges of the flaps Ia will bear against the edges of the walls 6 or the catches It will bear against the edges of said walls 6 as indicated in Fig. 2.

This arrangement may be effected in va- 5l rious ways, for instance each of the flaps may be mounted upon a rotatable pivot as shown at m, Fig. 7, so that these side flaps may be turned into a vertical plane at right angles with respect to the hinge d, as shown at Fig. 7 when it is desired to turn down the extension flap f, in which case vertical slots n, n are provided at the front of the cabinet through which the said side flaps is can pass when the amplifier is collapsed. It will be seen that when the flaps 7c are turned into the position shown at Fig. 7 upon being turned back they clear the edges of the side walls 6.

In other cases the side flaps 70 may be rigidly fixed to the side edges of the extension flap 7, in which case the slots n must be of somewhat triangular shape, that is made wider at the bottom than at the top, in order to enable the side flaps to pass into the cabinet when the amplifier is collapsed.

Any suitable means may be provided for holding the amplifier in the open position. This may for instance consist of a rod 1) hinged at g to the top board a, the other end of the rod 2 being adapted to engage in any one of a number of teeth upon a rack 1' provided at the side as seen clearly in Fig.

2. One of these rods 11 may be provided on each side. The ordinary'elbow communicates with the back of the amplifier and 30 with the tone arm and sound box in the customary manner, and the machine is furnished with all the otherusual parts incidental to a gramophone.

Referring to the modified form of the 5 machine shown at Fig. 6,- in this case the elbow in connection with the tone arm is dispensed with and the aperture of the tone arm comes directly beneath the top board a of-the amplifier, the hinge d of which in this case is arranged near the top edge of the cabinet.

The top of the cabinet may be raised as a whole, in which event the downwardly extending side walls 6 are so located as to give the desired tapering passage, or in other cases a portion of the top of the cabinet may be cut out in tapering form and hinged to form the top board 0 of the amplifier and have the downwardly extending 10 side walls 6 attached along the side edges thereof.

The form of the machine shown at Fig. 6 is more compact than that illustrated at Figs. 1 to 5, and is suitable for a cheap class of machines.

The front extension flap 7 is in this case preferably not of tapering form but rectangular as shown in the diagrammatic plan at Fig. 8.

The rectangular extension flap may also be used with other forms of the machines where desired,

A door or doors may be provided in any suitable position for enabling access to be obtained to the turn table and sound box.

In general the construction may be varied to suit requirements according to the instrument to which the invention is to be adapted.
