Specification of Letters Patent.

Patented Oct. 26, 1-909.

Application filed January 20, 1908. Serial No. 411,828.

To all whom it may concern:

lie it known that I, lis'rnu lY-ianim, a citif zen of the lInited States, and a resident of Orange, in the county oflissex and State of has for its objectthe provision of (1) means i i applied to the traveling sound box carriage which permits a slight elevation thereof, such as is necessary in order that the sound record ma be applied to or removed from the mandrel, but which prevents the said carriage from being raised more than the slight distance referred to; and (2) an im proved form of interchangtatble gearing for operatively connecting tliema idrel and feed screw shaft. and which can be shifted so as to change the relative speeds of said rotary members, whereby the instrument will be capable of operatingupon sound records of different pitch, as for example, sound records having respectively one hundred and two hundred threads per inch.

With these ends in view my invention consists in the features hereinafter described and claimed.

Reference is hereby-made to the aeeompanying drawings, of 'Which Figure 1 is a front elevation, partly in section, showing a phonograph constructed in accordance with my invention; Fig. 2, is a plan view of a portion of the phonograph showing the interchangeable gears for operatively connecting the mandrel and feed screw shaft; Fig. 3 is a side elevation of the base of the phonograph and its driving 1110- tor as viewed from the right in Fig. 1; Fig. t is a side elevation of the phonograph as viewed from the left, Fig. 1; Fig. 5 is a detail side view' of the movable frame or support which carries a part of the interchangeable gear mechanism; Fig. 6 is a rear view of the same; and Fig. 7 is a detail plan view of the means for holding the'starting and stopping lever.

The phonograph shown comprises a base or bed plate 1, from which the frame work of the driving motor 2 is suspended. The said motorisprefcrablyaspring motor comprising the usual spring barrel, countershafts, gears and governor shaft to which the governor is applied, and which comrises centrifugal weights 3 anda. slid'able friction disk at. The speed of the motor is regulated by a friction pad 5 of felt or other suitable material, which is secured to one end of an L shaped lever 6, which is pivoted at the point T to the post- 9 carried by the frame of the motor. The other arm extends immediately in front of the head of an adjusting screw 8, which is threaded in the )ost- J.- As the screw 8 is screwed into'thc post. 9 it permits the friction pad 5 to be moved away from the disk 4, and thereby allows the motor to run at an increased speed. A movement of the screw 8 toward the arm of the lever 6 causes the friction pad to move toward the disk l and thereby diminishes the speed at which the motor can run; thus a very simple adjustment is provided which permits, of the motor running at any'definite speed within the range at which it is capable of operating.

The means for starting and stopping the motor consists of a lever 10 pivotally connected at 11 to the post 12 carried by the motor frame, and-which carries at its lower end a pad 13-5, so situated as to be brought into contact with the disk 41-, for stopping the motor, said position being illustrated in Fig. 1. "When the. upper end of the level- 1O is moved toward the left, the pad 13'will be withdrawnfrom engagement-with the disk 4-, and the motor will thereupon start. The

17 each of which is adapted to receive the end of the lever 10. The spring holdsthe lever firmly in position at either end of the slot, and at the same time readily permits the lever to be moved from one extreme position to the other, oneposition being indicated in full lines, Fig. 7; and the other in dotted lines.

The means here described for regulating the speed and the starting and stopping of the motor are not here claimed.

. The phonograph also comprises a mandrel 1S rotatably supported in any suitable mannor, as for example, thc'ends of the mandrel may be journaled upon a horizontal rod 19, which is bolted at one end to the upright 20, formed integral with the base 1, and the mandrel is provided with a pulley 21 over which the driving belt from the motor runs.

A spur gear 22 is fixedly secured to the mandrel, and there is a spur gear 23 fixed to the feed screw shaft 24, which is rotata bly supported by the base 1 in any suitable manner. In order to operatively connect the gears 22 and 23 with interchangeable driving mechanism, I provide a frame or support 25 shown indetail in Figs. 5 and (5. This frame is applied to the upright 20 of the base 1, and is movably supported thereby in the following manner: The pin 26 which extends outward from the frame 25 passes through a boss 27 iptegral with the upright 20, and the same is provided with a removable head 28 which acts-as a stop for limiting the inward movement of the said frame, the outward movement thereof being limited by the engagement of the main body of the frame with the-upright 20. The frame 25 is also provided with a projecting arm 29 in whose extremity is threaded a screw 30 which is adapted to bear against the upper surface of the upright. 20, and which pro-- vides for a slight angular adjustment of the frame around the pin 26 as an axis. The.

end of the screw 30 is pressed against the surface of the" upright 20 by means of a spring 31, which is secured to said upright! by the screw 32, and. whose free end is bent into the shape clearly shown in Fig. t, so as to press downwardupon the arm 29 when the same is elevated by the adjusting screw 30. The spring 31 also acts as a guide for said arm 29' when the frame 25 is moved in and. out for the purpose of shifting the gears carried thereby. The said gears comprise two sets, one set consisting of a sin 'le spur gear rotatably mounted upon a stud 3% carried by said frame 25 and adapted to operatively connect the gears 22 and.23 when the frame 25 is inits extreme outward position as shown in Fig. 2. The other set consistsof atrain of spur gears 35, 36, 37 and 38 and said-train is so arranged as to operativelyvconnect the gears 22 and 23 when the frame 25 is in its extreme inward position.

The various gears are so proportioned that when the gear 33 is in mesh with the gears 22 and 23, the feed screw shaft 24 will be driven at theproperaspeed for operatively feeding the sound box carriage 39 with respect we sound record, the pitch of whose record groove is one oue-hundredths of an inch, and when the gear train 35, 36, 37 and 38 is in operative connection with the gears 22 and 23 the feed screw shaft 24 will be rotated at a speed. suitable for operatively feeding the sound box carriage with respect to a record the pitch of which is one twmhundredths of an inch.

Inorder to shift the gearing from the position shown in Fig. 2, all that is necessary to do is to move the frame 25 inward by pushing upon the head 28 of the pin 26,

so that the gear '33 will be moved'out of engagement with the gears 22 and 23, and the gear train 35, 36, 37 and 38 will be brought into operative relation with said gears, and in order to provide for slight variations in the position of the frame 25, which would tend to prevent the gears from properly meshing with the gears 22 and 23,

the angular adjustment of the frame 25, by

means of the screw 30, as previously described, is provided.

r The sound box carriage 39 is sleeved at its rear upon the guide rod 40, and its forward end rests upon the straight edge or track 41, a lift lever of the usual form being pivoted, upon the pin -13 and serving to elevate ,the

said carriage a sufficientdistanc'eto cause the stylus of the reproducer or recorder to clear the surface of the sound reco.rd, 1n order that the record may be removed from the mandrel or applied thereto, Further upward movement of the carriage is, however, preventedby reason of the engagement with from the carriage as shown inFig. i, andis so formed that its extremity will impinge against therear surface of the track ,t1, 111 ease the attempt is made to raise the car-j .90 the track ll of the arm ital, which depends I riage beyond the position to which it may be elevated by the lift lever 42, thus preventing i the carriage 39 from being swung 'com pletely around upon the rod 40, or into such a position aswould expose the feed nut its supporting spring.

, 11,; Having now described my invention, what,

I claim is:

1.111 a phonograph, the k:ombina -tion' the guide rod 40 and sound box carriage sleeved thereon, said carriage bemgmovable vertically sufficiently to enable the recordf ing or reproducing'stylus to clear the record surface, and means for preventing further vertical movement of the said carriage,'sub stantially as set forth. 4 i I r 2. In a phonograph, the combination of the guide rod 40 and sound box carriage sleeved thereon, .of a track 41, upon which the forward end of the said carriage is sup-..
