PHON OGRAPH.

Specification of Letters Patent.

Patented Aug. 6, 1918.

Application ala February 14, 191s. seriax No. 217,211.

To all 'whom t may concern:

Be it known that I, JOHN M. WADDELL, a citizen of the United States of America, Greenfield, in the county of Highland and State of Ohio, have invented a new and useful Improvement in Phonoaphs, of which the following is a specication.

An object of my invention is to produce an improved phonograph in which improved 'instrumentalities are employed for modiying the intensity of the sound waves without producing muiiledv effects, while simultaneously serving ornamental and useful (pui-Roses in an article of furniture other than onograph cabinet.

his and other objects are attained in the phonograph described in the following specification and illustrated in the accompanying drawings, in which;

-Figure 1 is a front elevation of a phonolgra h embodying my invention.

1g. 2 is a transverse sectional elevation taken on the line 2 2 of Fig. 1.

sol h Fig. 3is a plan'view of the phonograph embodying my invention, Ythe lid being completely ra1sed. p

. Fi 4. is a transverse sectional view taken on t e line 4 4. of Fig. 3, the lid being own in normal raised position. In the illustrated embodiment ofmy imroved phonograph I have shown a cabinet having the form of an old fashioned drop ,leaf table, the lid 5 of the phonograph being the table top when in closed position, and the dro leaf of the table forming the Vsound modi ying damper 6 of the phonoph when dropped. Beneath the. lid 5 have rovided a box-like container f? which is divi ed into two

compartments

8 and 9, in thel former of which the phonograph mechanism 10 is mounted and in the latter of which the record racks 11 are located.

The phonograph mechanism consists of the usual record turn table 12 located above a platform 13 beneath whichthe motor for rotating the turn table is locat he usual sound box 14 and tone arm 15 hi are .located above the platform for coperatlon 4with the turn table, and the sound amplifying horn 16 which is located beneath the platform an'd which has its opening in the sideof the container 7 as shown in Fig. 1.

Between compartment 8 and compartment 9 I have located two

walls

17 and 18 which are spaced apart and between which is lolocated and may be of any cated a mechanism for controlling the operting the movements of these elements to he independent if desired. This mechanism consists of an arm 19 which is pivotally mounted between its ends as shown in l `igs. 2 and 4, a link 20 which connectsy the arm and damper, and a spring 21 which connects the lower end of arm with a bracket 22. The upper end of arm 19 is provided with a roller 23 which is caused to bear upon and roll in contact with a track 24 secured to the under side of lid 5. The track is provided with a portion 25 which the roller engages when the lid is in closed position as shown in Fig. 2, and a portion 2G which is engaged by the roller when the lid is raised as shown in Fig. 4. Link 20 connects arm 19 and damper G by means of a pin 27 which cngagcs a notch 28 in the link, and a bracket 29 which is secured to the damper and which pivotally connects with the opposite end of the link.

In compartment 9 the record racks 11 are desired type, the racks shown being preferred since they hold the records in staggered relation to enable them to be conveniently removed. A receptacle 30 is provided lor the reception of a record duets-i'.

In the operation of my improved phonograph the lid is raised to the position shown in Fig. 4, spring 21 acting simultaneously to cause roller 23 to assist in the lifting operation and when the Vroller engages ortion 2G of. the track 24 the lid is retalne( in the lifted position. If notch 28 of link 20 has been disengaged from pin 27 previous to lifting lid 5, the notch and

28 and 27 will engage when the lid has been brought to position shown in Fig. 4. If it is desired to close the lid after engagement of the notch and pin, the lid is lowered and in so doing, the link, through its connection with arm 19, is caused to swing damper 6 outwardly to the position shown in Fi 2. This results in opening the mouth o the amplifying chamber 16 as shown in Fig. so lthat the fuli volume of sound from a record being played. may be had. 'When the lid is down and the damper raised, a table top of good proportions is obtained, and in. order to hold'thc lid dawn when pressure is brought to bear upon damper 6, I have proviiled o Patch 3l of any suitable form adapted to secure the lid to the body.

Should it he desired to lower the damper independently of the lid movement, the link may be disengaged from arm 19 by pushing upon the link from the under side of the damper when it is in the raised position as shown in Fig. 2. or by disengaging the link from the arm previous to the loweringl of the lid, by means of

notches

32 and 33 which permit the, link to be grasped by the fingers. In my improved construction I have produced a phonograph which provides a sound damper which operates to reduce the volume of the sound without giving it the usual characteristic boxed in effect. This is because of the space 34 provided between the damper and the end of the horn. The sound waves are free to pass out around the bottom and ends of this space, but, because they are 'interruptedl they do not issue forth in the same intensity as when the damper is raised. 'hen the damper is raised it acts somewhat as a sounding board adapted to aid in the reloduction of the selection beingr played.

aving thus described my invention, what I claim is:

1. A phonograph consisting of a cabinet having a phonograph mechanism therein, a sound amplifying horn connected with said mechanism and opening in a wall of the cabinet adjacent to the mechanism` a sound dan per pivotally mounted adjacent to thtI upper edge of the horn opeuin, a lid pivotally mounted on the cabinet above the mechanismA and means connecting the lid and the damper, whereby the damper will be raised when the lid is closed and lowered when the lid is raised.

2. A phonograph consisting of a cabinet` having a phonograph mechanism therein, a

sound amplifying horn connected with said mechanism and opening in a wall of the cabinet. adjacent to the mechanismv` a sounl damper pivotally mounted adjacent to the upper edge of the horn opening, alid pivotally mounted on the cabinet above the mechanism, and means detachably connecting the lid and the damper, whereby the damper will be raised when the lid is closed and owered when the lid is raised or whereby the damper may be detached from the lid for independv ent operation thereof.

In testimony whereof, I have hereuntt` subscribed my name this eleventh day of February, 1918.
