AUTOMATIC CHECK FOR PHONOGRAPHS.

Specification of Letters Patent.

Patented Get. 18, 1910.

Application filed July 26, 1909. Serial No. 509,475.

I To all whom it may concern:

States, residing at White Bear Lake, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Automatic Checks for Phonographs, of which the following is a specification.

This invention relates to improvements in automatic mechanism for stopping the motor of a phonograph when the reproducer has reached the end of the record cylinder:

An object of my invention is to provide an extremely simple and inexpensive device of this character which may be readily attached to phonographs at present constructed and which may be adjusted to conform to graph mechanism.

prises the main longitudinal the various Another object is 4 to provide a device which will be automatically set in the proper position for stopping the motor of the machine, when the starting lever has been moved to its proper operative position,

A further and more particular object is to provide a controlling lever and support therefor of novel and simple construction.

In the drawings; Figure 1 is a perspective view of the large size type of phonograph, showing the stop mechanism applied thereto, Fig. 2 is a similar view of-a smaller size type of machine, with a slight modification of my device, Fig. 3 is a detail view-of the controlling lever, comprising my invention.

Referring to Fig. 1 of the drawings, 1 in-- dicates the casing for the motor mechanism, and 2 the frame This mechanism comshaft 3, the cylinder 4, the feed block 5, the reproducer arm (3, and the reproducer 7. These various elements comprise the principal features of the ordinary phonograph as at present constructed and are su tably connected and 0perated by the motor mechanism contained within the casing. In this type of machine the stopping lever 8 protrudes from the casing through a slot 9 formed in the base plate of the supporting frame 2, and extends for some distance above the top thereof. To the upper end of this lever one end of the longitudinally extending controlling lever 10 is secured, this lever being supported upon the base plate of the frame 2 by means of links 11 which are pivotally supported upon said lengths of the records which are upon the cylinder.

which supports the phono- I plate and connected to the controllinglever, Be it known that I, JOHN J. Monmssnv, a citizen of the United so that longitudinal'movement of the controlling lever will oscillate the starting lever, and the controlling lever will rock upon the links. The other end of the controlling lever 10 is extended rearwardly and upwardly as shown at 12 and its posit-ion with relation to the reproducer of the phonograph mechanism, is such that the same will contact with the portion 12 of the controlling lever to stop the operating mechanism, as will be later described. The links llare carried by suitable bracket platesll having two perforations therein receiving suitable fastening members engaged with a part of the phonograph frame, the plates being provided at one side with an upwardly extended perforated ear 11 in which there is engaged a suitable pintle, upon which thelink is pivotally carried. The brackets 11, the links and the two members of the controlling lever,10 are all formed of sheet metal, which reduces the cost of the device to a minimum and simplifies its construction to a marked degree) V To provide for the stopping of the mechanism at various periods of the longitudinal movement of the reproducer, the arm 12 cured to the controlling lever 10 and lead justable with relation to the end of the cylinder. A recess 13 is formed in one side of the controlling lever 10, said recess opening atthe end of the lever opposite to the of connection with the starting lever 8 and this extension 12 has-its lower horizontal point portion suitably reduced in width and thickness and is disposed slida-bly within the recess 13, the shoulder formed by the reducing of this horizontal, portion being adapted to abut the end of the controllinglever, when-at the limit of its inward movement. A longitudinal slot 14 extends the greater portion of the length of t-hehorizontal portion of the member 12, the shank of the set screw 15 being extendedthrough the same, and screw threadedly engaged in the extremity of the controlling lever, by which means it will be seen, that the member 12 may be extended outwardly longitudinally of the phonograph cylinder, so that the wardly extended portion rearwardly and up thereof may be disposed to engage the reproducer at the point at which the record of the cylinder terminates. The set screw 15 machine.

't peo will secure the member 12 in its adjusted po- 11, which are pivotally connected with the base of the frame 2 will thus be disposed at an inclination to the controlling lever and when the starting lever is again actuated to start the operating mechanism, the controlling lever will be drawn to the left, whereupon the links 11 will vagain assume their vertical positions and the rear ardly and upwardly extending end portion of the controlling lever will be returned to its normal operative position.

In Fig. 2 I have shown my improved stoppin mechanism applied to the smaller phonograph now in common use.

11 this COIIStI'L'lCtlOIl of the machine, the main shaft 3, above which the feed block 5 is disposed, is located behind -nd in parallel relation to the cylinder 4. T he reproducer arm is directly connected with the shaft 3, and extends over the front of the cylinder and has secured therein the reproducer 7', thus greatly contracting the length of the The stopping device does not essentially differ from the construction which is employed in the machine shown in Fig. 1. In this form, however, but one link 11 is necessary to support the longitudinal controlling lever 10. This link is pivoted to the lever and to the base of the supporting frame, and operates inasimilarmanner to the links 11 as previously described. One end of the controlling lever 10' is secured to the upper end of the starting lever 8, and is adapted to actuate the same to start and stop the operating mechanism when moved to either end of the slot 9. The other 'end ofthe controlling lever is extended rearwardly and upwardly and is adapted to be engaged by the lower end of the reproducer to move the starting lever to the right, when the reproducer has reached the end of the record upon the cylinder. The controlling lever 10 will also returned automatically to its normal operative position by the movement of the starting lever to the left when it is desired to start the operating mechanism.

' mazes From the foregoing it will be seen that I have provided an extremely simple inexpensively'constructed device which may be readily secured upon phonographs of the various types as at present constructed, and requires no especial provision by means of which the same is to be attached to the supporting frame. I My improved stop mechanism is particularly adapted for use upon commercial phonographs, where-it is essential-that the operator should be relieved from the many attentions which it is necessary? that he should give to the machine during the transcription of the record. .By the use of my improved stop mechanism the operator may give his entire attention to the elucidation of the matter recorded upon the cylinder, whereby much better results may be secured than have heretofore been possible.

What is claimed is An automatic stop for phonographs or the like, comprising a combination with a frame, a lon tudinally movable reproducer and an oscil ating starting lever projecting upwardly through the frame, of a controllin lever secured at one end to the a per en of the starting lever, said controlling lever having a long tudinal recess formed in one side thereof and opening on the opposite end to that secured to the starting lever, a bracket plate secured on the frame below said controlling lever, said plate having an upwardly extending perforated ear, a intle therethrough, a link pivotally mounte upon said pintle and pivotally connected to said controlling lever intermediate of its length, a rearwardly and upwardly extended arm having a horizontal extension, said horizontal extension being reduced in width and thickness for a greater portion of its length, said reduced ortion being provided with a longitudinal s ot throughout its length, said reduced portion being slidably. mounted in .the recess, a set screwextendingthrough said controlling lever, 'said arm being ad justably disposed in the path of therepro- JOHN vJ.
