REWINDING- DEVICE FOR, PHONOGRAPH MOTORS.

Application filed May 26, 1922. Serial No. 563,893.

T all whom it may concern:

Be it known that I, LEONARD E. Porrn, a citizen of the Unitedstates, and resident of Fall River, in the county of Columbia and State of Visconsin, have invented certain new and useful Improvements in Rewinding Devices for Phonograph Motors; and I do hereby declare that the following isia full, clear, and exact description thereof.

My invention refers to phonographs or talking machines, and it has for its object to provide a simple, economical, and'effective rewind attachment :to the spring motor, usually employed in such machines, whereby said motor is manually wound by a single pull movement to store the necessary power for completely demonstrating a record of ordinary type, whereby the objectionable feature of a motor becoming run down during its action upon a record is obviated, and whereby it is unnecessary, at any time, to completely wind the motor by the ordinary method of hand cranking. v

A further object of the invention is to pro- 25 vide a manually controlled re-wind attachment which may be adjusted to re-wind in proportion to the complete number of revolutions required in operating upon a record. Thus,by this means, obviously the operator, when inserting a fresh record, will, by a single movement of the attachment, wind the motor so as to completely play the record so inserted.

Another object of my invention'is to provide an attachment for re-winding the motor, the arrangement and construction of which is such that a gear train, associated with a spring drum mechanism and clutch, when actuated manually, will impart a predetermined number of spring Winding revolutions to the motor shaft, the clutch permitting free movement in a reverse direction of the motor shaft, whereby the re-winding attachment remains inactive during the time that the spring motor is operating to drive or impart rotation to the record disc.

With the above and other objects in view, the invention consists in certain peculiarities of construction and combination of mechanical elements as will be hereinafter fully set forth with reference to the accompanying illustrations and hereinafter claimed.

In the drawing Figure 1 represents a plan view of the standard motor driven phonograph or recording machine, having attached thereto a re-wind mechanism embodying the essential features'of my invention, with parts of the phonograph being broken away and in section to more clearly illustrate details of con struction pertaining to my invention.

Figure 2 is a detail cross section of the same, the section being indicated by line I 22 of Figure 1, and

Figure 8 is another detail cross section, as indicated by line 33 of Figure 1.

Referring by characters to the drawing, A

I represents the cabinet or casing of a ,phonograph or recording machine, B a housing which contains a motor of the spring type, (not shown), and C the motor shaft. D represents the ordinary type of disc for carrying the records, which disc has rotatory movement'imp'arted thereto through a suitable "gear connection, (not shown), from the motor. Y

Secured to the'inner wall of the casing is a U-shaped bracket 1, having journals for'an arbor 2, which arbor is positioned parallel with the motor shaft 0. Rotatably mounted upon the arbor 2 is a toothed gear whee13, which gear Wheel meshes with a toothed pinion 3, that is fast on the motor shaft 0. The hub of the gear wheel 3 carries a spring pawl 4, which pawl engages a ratchet wheel 5, that is secured to the arbor 2. "Owing to this clutch connection, when the gear :wheel'3 is rotated in the direction, as indicated by the A arrow in Figure 2 ofthe drawingffrom, the arbor 2, it will impart rotation to the motor shaft C, whereby the motor is wound a predetermined number of turns with relation to a single rotation of the gear wheel 3.

When power is imparted to the shaft C by the motor spring in a reverse direction, I

it will be noted that the clutch controlled gear wheel 3 will revolve loosely upon the arbor, whereby the mechanism associated therewith, will remain inactive.

Secured to the arbor 2 is a drum 6, havingcoiled thereabout a cable or runner 7 the inner end of which is secured in any suitable manner to the faceof the drum. The runner is extended through a slot 8 formed in the wall of the casing A, and said runner, at this point, has attached thereto any convenient handle or grip 9. Also secured to the arbor 2 is the innerv end of a coil spring 10, the outer end of the same being secured to a stud 1, which projects from the bracket 1.

It will, also, be noted that in order to maintain proper relationship between the re-winding attachment and the motor shaft (3, the bracket is provided with a hub 0, which forms a journal about the shaft C, whereby the same is held in position with relation to the re-winding mechanism and its train of gears. Obviously, the clutch mechanism, just described, may be utilized in connection with the pinion 3, whereby the same result is attained, and it is, also, an obvious mechanical modification, in connection with this change of clutch, to rigidly attach the winding drum and its spring control to the large gear wheel 3, in which case the coil spring 10 could be readily housed within the shell of the drum 6.

From the foregoing description, it is also within the scope of my invention to utilize some type of lever in connection with the runner 7 which lever may extend out through a suitable slot in the casing, whereby the manual power applied for re-winding the motor can; be increased through the leverage connection. It will, also, be seen that when it is desired to play a record, the operator, after inserting the same upon the disc D, will grasp the grip 9 and draw out the runner 7 its approximate full length, whereby the drum and its arbor 2 will re tate in the direction as indicated by the arrow in Figure 2.

In this re-wind operation, it will be noted that the auxiliary spring 10 will also be wound, due to rotation of the arbor, and the gear wheel 3 will thereby impart winding movement to the shaft C to thus wind up the spring motor for storing suflicient power to completely play the record inserted in the machine. Upon release of the grip 9, the

auxiliary spring 10 will cause the arbor to rotate in a reverse direction, whereby the runner will be re-wound upon the drum- 6 naeaeoa and in performing this operation there will be no movement imparted to the gear wheel 3, due to the slip-clutch connection between it and the arbor. In other words, the gear wheel 3 is loosely mounted upon the arbor shaft and rotates in one direction only, while the drum oscillates back and forth to impart motion to the motor shaft C and to rc-wind the cable or runner 7.

While I have shown and described a simple exemplification of my invention minutely as to details of construction, it is understood that I may vary such details of con-- struction within the scope of the pending claim, as they may hereinafter be interpreted by those skilled in the art.

It is, also, apparent from the foregoing description that I may, in some cases, provide an adjustable stop, which may be associated with a runner, and which step will predeterminedly limit the re-wind movement. This suggestion may, in some cases, be advantageous where records are used of greater or lesser diameters. I

I claim:

The combination of a phonograph, including a spring motor having a winding spindle, and a rewinding mechanism comprising a bracket having a bearing for said spindle, a second shaft carried by said bracket,- a spring urged drum mounted upon said shaft, a relatively large gear carried by said shaft, a relatively small pinion carried by said spindle and meshing with said gear, a clutch adapted to operatively connect said relatively large gear and said shaft when said drum is rotated in a direction against the action of the spring, a flexible member wound about said drum, and a manually operable handle projecting from said phonograph and attached to said flexible member.

In testimony that I claim the foregoing I have hereunto set my hand at Fall River, in the county of Columbia and State of Wisconsin.

LEONARD E. POPPE.
