To all whom it may concern:

Be it. known that I, CHARLES M; lrlrzenns, a citizen of the United States, residing in the city of Newark, in the county of Essex and State of New J ersey,have invented certain new and useful Improvements in Phonographs, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it per- .tains to make, construct, and use the same, reference being had to the accon'ipanying drawings, and to letters of reference marked thereon, which form a part of this specification.

The object of my invention is to increase the simplicity in construction and. operation of the phonograph, by decreasing the numher of parts of which the machine is composed, by lessening or avoiding the necessity foradjustmcnt of the various parts in practice, andby increasing the convenience of manipulation of the machine. To this end, I have made many changes, all with the objects of increased simplicity, convenience, and efliciency.

Heretofore, it has been cnstomar 1 to rotate the mandrel shaftby directly connecting the same with the motor shaft.- by snitable pulleys, belts or gear wheels. One feature of my invention is an improvement upon this arrangement; and consists in rotating the mandrel shaft without directly connecting it to the motor shaft. by means of pulleys, belts, gear wheels or the like, by causing said mandrel to rest upon and be rotated by frictional engagement with a belt which passes over a. pulley on the motor shaft. and overa. pair of pulleys and under an idler, which are conveniently secured in a case upon the top of the machine, and in which the mandrel shaft is supported and rotated.

In the accompanying drawings forming a part of this specification, Figure 1 is a side elevation of my improved machine, partly in section. Fig. 2 is a plan view. Figs. 3 and 4 are end elevations of the same; and Fig. 5 is a vertical sectional view taken on lines a'-a: of Fig. 1, looking in the direction indicated by the arrow.

Similar letters of reference refer to like parts throughout the specification and drawmgs. A

In the drawings, a represents the case of the machine andb-the ton. to the under side I of which is mounted in any convenient manner, a motor 0 of the usual type. A casing u:

of any desirable shape is secured to thetop of the machine, and provided with two small pulleys a and an adjustable idler f. A drirmg pulley g is secured to the motor shaft, over \\-'ll1Ch the belt h passes, which drives and also passes-over the pulleys a and undcr' the idler f, which are located in the casing 11. In the drawings. I have shown an elongated slot. h in both sides of the casing.

through-which a stud 7L passes. upon which is loosely mounted the idler 7', said stud being provided at one end with a knurled nut h". which together with the stud atl'ordsa ready means for changing the vertical position of the idler, in order to adjust the belt 72-. An adjustable bracket 1' provided with a nut section 1 is cbnvenicnttr mounted upon the top I) of the machine.

The phonogram -mandrel is mounted upon a shaft /.'-and has extending from one side thereof, the feed screw 1 which is in engagement with the *nut section i. The bracket (Z in its top side, is cutaway at 011, so as to ex iose the bolt l2.

From the oregoing description. it will be seen that the phonogram carrying shaft is is in no way geared to the motor by gears or belts, as has been customary heretofore. but that the shaft l simply rests upon the belt. l1, between the two )ulle' vs c, and is driven by frictional engagement therewith,

and that the other end of the shaft which is screw-threaded. is m engagement wlth the screw-threaded nutscction 2 by means of which the phonogram cylinder is slowly displaced in the direction indicated by the the feed screw Z which extends from one end of the phonogram mandrel j.

4 represents a sound box of the usual type, convenientl secured to the top of the machine, and, esigned to receive a sound horn of the ordinal kind.

From the a ove description, it will be phonogram carrying shaft.

apparent that I have produced a. phonegraph possessin' the features of advantage enumerated as esirable, and-I wish it .to

be understood that I donot desire to.be

limited to the exact details of'construction shown and described, as obvious modificain. the art.

I claim: V y

1. In a phonograph, the oombinationof a motor, a .frictionallydriven phonogram tions will suggest themselves to those skilled carrying shaft, and ,means' arranged upon 3; In a phonograph, the combination of a motor, a frictionally driven phonogram carrying shaft, a supportprovided with a nut sectionfor supporting one end of said shaft, and driving and. supportingmeans operated by said motor for supporting and frictionally driving -.the other end of said 4. 'In a phonograph, thecombination of a motor, a frictionally driven phonograni carrying shaft, a support provided with a swiveled nut section for supporting one end of said shaft, and an adjustable driving and supporting means operated by said motor for supporting and frictionally driving theother end of said phonogram carrying shaft.

5. In a. phonograph, the combination of a motor, alpair of pulleys connected by a belt with the motor and a phonogram carrying shaft resting upon and supported by said belt and driven by frictional contact therewith.

6. 'In aphonograph, thecombination of "a motor carrying a pulley, a pair of pulleys mounted in a casing and connected by a belt with the pulley on-the motor, and a phonogram carrying shaft resting upon and supported bysaid belt and being driven by frictional engagement therewith.

-7. In a phonograph, the combination'of a motor, a pair' of pulleys and an idler mounted 'in a casing and connected by a belt with the motor,'and a phonogram carrying shaft resting upon and supported by said belt and being .gagement therewith. -8. In a phonograph, the combination of a motor carrying a'pulley, a pair of pulleys mountedin a casing and connected by a belt with the pulley on the motor, a support provided with a swiveled nut section and aphonograin carrying shaft resting upon said belt and swiveled nut sectionand being grliven by frictional engagement with said 9. In a phonograph,.the combination of a spring motor, a casing provided with a pair of pulleys and an idler, said pulleys and idler being connected by a belt withsaid spring'motor, a support provided with a swiveled nut section and a'phonogram carry:

ing shaft resting. upon said belt and swiveled nut section and being driven by frictional engagement with said belt.

10. In a phonograph, the combination of a motor, a pair of pulleys and an adjustable idler mounted in a casing, and connected by.

driven byfrictional .en-

a belt with the motor, a support provided with-a nut sectionand a phonogram carrying shaft resting upon said belt and support and beingdriven by frictional engagement with said belt;
