JOSEPH BORNAND, OF PELHAM, AND BUROHARD THOENS, OF NEW YORK, N. Y.

PHONO GRAPH.

Specification of Letters Patent.

Patented at... 1 o, 1907.

To all whom it may concern:

Be it known that we, JosnPH BORNAND, a citizen of the Republic of Switzerland, residing at Pelham, 1n the county of Westchester, State of' New York, and BUROHARD THOENS, a subject of the Emperor of Germany, residingin the city, county, and State of New York, haye invented certain new and useful Im rovements in Phonographs, of which the ollowing is, a specification.

The invention relates to phonographs or talking machines in which the sound tube is stationary and the record is movable.

It resides in the means for mounting the sound tube and for mounting and operating the record support, so that the record will be automatically moved by the engagement of the stylus of the sound reproducer with the spiral groove in the record. The record supppirt is so mounted and connected with a ed source of power that it maybe driven without any interference with its motion in a straight line beneath the'stylus of "the reproducer.

In the accompanying drawingsFigure 1' is a sideelevation showing the device; Fig. 2 1s a plan of the same device; Fig. 3 is an elevation of a modified form of the device; and

' Fig. 4 is a plan viewof this modification.

Referring particularly to Figs. 1 and 2, 1 represents a box or casing in which there may be placed any ordinaryform of motor.

' A s indle lettered 2 extends through the top of t e casing near one side and is adapted to be driven by the motor within the casing. Two parallel track-ways 3 are placed on top of the casing at opposite sides of the spindle 2 These track-ways are inclined to the horizontal andserve as supports and guides for the rollers 5 of a movable carriage or frame 4/ The frame 4 has a cut away portion which ermits it to straddle the spindle 2. In the rame 4 is mounted the spindle 6 which carries at its upper end the circular flat disk 7 which serves as a support for the record. This plate 7 has on its lower side a proj ection 8 which fits over the pin 9, passing through the spindle 6, and thus the plate is locked to the spindle and made to rotate therewith. A third spindle 10 is pivotally mounted upon two arms lettered 17 extending from the spindle 2, and also upon two pivoted arms 18 extending from the spindle 6. On the spindle 2' and between the arms 17 is mounted a sheave 11, and opposite this sheave on the spindle 10 is mounted the sheave 12. Between the arms 18 a sheave 1 3 is mounted on the spindle 10, and a corresponding sheave 14 is mounted on the spindle 6. These sheaves are connected by

belts

15 and 16, so'that any rotation of the spindle 2 is imparted to the spindle 6' and to the record support 7. The sound tube 19 and reproducer 20 are fixedly attached to the casing 1 by means of the bracket 21 and clamp '22.

In the modification shown in Figs. 3 and 4, instead of using the inclined track-ways we have provided a spring 23 connected by a band 24 to the carriage 4. This spring, like the inclined ways, tends to move the car- .riage in onedirection. In this modification furthermore we have substituted for the! sheaves and connecting belts the meshing and

gear wheels

25, 26, 27 and 28. It will be understood that other forms of connecting gearing or operating means might be em loyed instead of the particular forms descrlbed, without departing from the main plan of my invention- In operation the flexible connection between the spindle 6 and spindle 2 which includes the

pivoted arm

17 and 18 permits the carriage to move freely towards or away from the spindle 2 without interfering with the rotation 'of the record support. The inclined track-ways ,3 in Figs. 1 and 2 and the spring 23 in Figs. 3 and 4 are so. adjusted and proportioned as to almost, but not quite,

' overcome the friction and inertia of, the ,car-

riage and operating parts, so that very little force is required to move it in one direction.

When it is desired to use the device to repro duce a record, therecord is placed on the sup ort 12 and the stylus of the reproducer 20 is placed in'the outer turn of'the spiral groove in the record and power is applied to the spindle 2, so as to rotate the record. The stylus will follow the spiral groove and being stationary will, by contact with that groove, move the record and its supportlng parts, including the carriage, transversely beneath it. I

We have found that the character of the sound produced is much improved by having the sound tube fixed and stationary instead of having movable parts. We believe that the movable parts interfere with the proper transmission of the sound and we desire to claim broadly this feature of a-fixed' in which it is moved by the reproducer.
