BENJAMIN C. SCHUTTE, OF HOOK, NEW YORK.

SPECIFICATION forming part of Letters Patent No. 762,661, dated J une 14, 1904.

Application filed October 18, 1902. Serial No. 127,766. (No model.) 6

To all whom it may concern:

Be it known that I, BENJAMIN O. ScHnTTE, a citizen of the United States, and a resident of Red Hook, in'the county of Dutchess and State of New York, have invented certain new and useful Improvements in Regulating Mechanism for Sound Reproducing Machines, of which the following is a specification. My invention relates tomechanism operated by spring-motors, and more especially pertains to said mechanism when adapted to the requirements of sound-reproducing machines of the class represented in a general way by phonographs and graphophones; and the principal object of my invention is to provide an improved form of duplicate brake mechanism to regulate the operative speed of the springoperated gearing. By my invention I also provide an improved driving-gear andin a general way an improved construction of mechanism for devices of the class named. 4 The construction of the improvement will be fully described hereinafter in connection with the accompanying drawings, which form part'of this specification, and its novel features will be defined in the appended claims.

In the drawings, Figure 1 is a reverse or bottom planview of a machine embodying the invention. Fig. 2 is an end elevation of the same. Fig. 3 is a detail sectional view on the line 00 w shown in Fig. 1. Fig. 4 is a detail sectional view on the line y 3/ shown in Fig. 1. Fig. 5 is a fragmentary View showing winding mechanism.

Corresponding parts in all the figures are denoted by the same reference characters.

The reference-numeral 1 designates the bedplate of the machine, secured to the under side ,of the lid 2 of the cabinet, within which the mechanism is incased.

3 and 4 designate parallel brackets depending from the bed-plate and provided at their ends with bearings 5 for the motor-shaft 6. Upon this shaft 6 is mounted a cylinder 7, containing the springs for driving the motor. I preferably employ what is known as a triple spring motor, containing three springs; but as the motor proper, embodying the cylinder and springs, forms no part of the present invention a more detailed description thereof is not deemed necessary.

Awinding gear-wheel 8 is mounted upon the shaft 6 at one end of the cylinder to mesh with a pinion 9, mounted upon a windingshaft 10, and concentric with said wheel 8 is a ratchet-wheel 11, coacting with a pawl 12 to prevent backward movement of the motorshaft. At the opposite end of the cylinder a driving gear-wheel 13 is mounted upon the cylinder or casing 7 said gear-wheel meshing with a pinion 14., fixed upon a shaft 15, supported in bracket-bearings 16 and 17, depending from the bed-plate.

Upon the outer end of the shaft 15, on the outer side of the bracket 16, is a gear-wheel 18, adapted to mesh with a pinion 19, fixed upon the outer end of a shaft 20, supported in bearings in the

brackets

16 and 21, depending from the bed-plate.

shaft 24, the latter being revolubly supported at its upper end in a bearing formed in the bed-plate and adjacent to its lower end in a bearing formed ina plate 25, secured to the bed-plate by a plurality of parallel vertical arms 26. I

Fixed to the lower end of the shaft. 24 is a gear-wheel 27, meshing with a pinion 28 on a vertical power-shaft 29, said shaft 29 carrying at its lower enda gear-wheel 30, meshing with a worm 31 on the governor-shaft 32. The governor-shaft 32 is supported in bearings formed in parallel bracket-arms 33 and 3 1, depending from 'the plate 25. A button or keeper 35 is pivoted to the bracket-arm 33 and adapted to bear against the adjacent end of the governor-shaft to prevent longitudinal play thereof.

Upon the governor-shaft 32 is a fixed collar 36, connected on opposite sides by means of expanding springs 37 to the hub 38 of a disk 39, fixed upon the end of the governor-shaft and having a sleeve extension 40, formed with diametrically opposite slots into which extend pins 11, projecting from the shaft. On each spring 37 is secured a weight 37.

Fulcrumed to one side of the plate 25 ad- A bevel-gear 22 on' the inner end of the shaft 20 meshes with a bevel gear-pinion 23, mounted on a depending jacent to the disk 39 is a bell-crank lever 42,

provided at the end of its depending arm with a pad or shoe 43, of rubber or equivalentmaterial, which isadapted to bear against the inner face of the disk.

The forward end of one arm 42' of the bellcrank lever 42 is connected to a screw 44, extending through an opening in the cover of the cabinet and is provided with a knurled knob 45. A spiral spring 46 surrounds the pin 44 below the cover.

Projecting from the plate 25 is a sleeve or housing 60, Within which is mounted a brakeshaft 47, provided at one end with an arm 48, to which is secured a brake-shoe 49, of leather or like yielding material. The opposite end of the brake-shaft 47 is connected to a lever 50, which extends through an opening in the cover and frictionally contacts a flat spring 51, arranged on the under side of said cover.

The brake-shoe 49 is adapted to engage the rim of the disk 39, while the spring 51 is arranged to frictionally contact the brakelever and hold it in the desired position either in or out of contact with the rim of the disk 39, according to Whether it be desired to stop or to start the mechanism. It will be readily seen that the parts which control the operation of the mechanism of the instrument may be operated by means of the

members

45 and 50, which are readily accessible to the operator, and that said parts are void of complication and certain of operation.

Power applied by the spring-operated cylinder 7 will be so communicated by means of the gear-wheel 13, pinion 14, gear-wheel 18, pinion 19, shaft 20, bevel gear wheel 22, bevelpinion 23, shaft 24, gear -wheel 27, pinion 28, shaft 29, and worm-wheel 30 to the worm 31, thus rotating the latter, and with it the shaft 32, carrying the pins 41, (one only being shown). By means of the collar 36 the governor, comprising the springs 37 and weights 37 is rotated with the shaft 32, and torsion of the springs 37 is prevented by means of the pins 41, which engage in the slots which are formed in the sleeve extension 40 of the hub 38, to which one end of each spring 37 is attached. The speed of rotation is regulated by means of the brakeshoe 43, which may be adjusted to various positions axially of the governor-shaft, said adjustments being effected by rotating the screw 44 by means of the knob 45, the screw 44 either raising or permitting the spring 46 to urge downwardly, as the case may be, the arm 42 of the bell-crank lever 42, thus moving the arm 42", and with it the brake-shoe 43, toward or from the disk 39. When the governor is rotated, the weights 37 are cenquired position frictionally contacts the disk 39 when the desired speed of rotation of the governor has been attained, thus preventing the mechanism from attaining a greater rate of speed than the one desired.

I do not desire to be understood as limiting myself to the details of construction and arrangement as herein described and illustrated, as it is manifest that variations and modifications may be made in the features of construction and arrangement in the adaptation of the device to various conditions of use without departing from the spirit and scope of my invention and improvements. I therefore reserve the right to all such variation and modification as properly fall within the scope of my invention and the'termsof the following claims.
