BRAKE FOR PHONOGRAPHS.-
APPLICATION FILED MAR. II. m1.
Patented Mar. 19, 1918.
.. h I JIIIF MICHELANGELO IBONO, OF NEW YORK, N. Y.
4 v BRAKE FOB PHONOGRAPHS.
Specification of Letters Patent.
Patented Mar. 1c, 1918.
Application filed March 17, 1917. Serial No. 155,396.
To all whom it may concern:
Be it known that I, MIOHELANGELO BONO, a citizen of Italy, and a resident of New York city, in the county and State of New York, have invented certain new and useful Improvements in Brakes for Phonographs, of which the following is a specification.
This invention relates to a novel phonographic brake which is simple in construction, may be readily set to engage the turn table with records of diiferent lengths, and is reliable in operation.
In the accompanying drawing:
Figure 1 is a plan of a brake embodying my invention;
Fig. 2, a side view thereof;
Fig. 3, a front view;
Fig. 4, an enlarged section on line 4-4 Fig. 1, and
Fig. 5, a similar section on line 5-5 Fig. 3.
The casing 1 of the phonograph carries the turn table 2, and is furnished with a bracket 3 in which is mounted the pivoted tone arm 4, all as usual. At one side of easing 1, there is pivoted at 5 to a fixed bearing 6, a lever 7, having an upwardly bent end 8 that constitutes a pusher. This pusher is adapted to engage the rear end of a tubular plunger 9, into the front end of which is fitted a flexible plug 10 constituting a brake shoe, that .is adapted to engage the turn table 2. Plunger 9 is movable within a tubular bearing 11 fastened to casing 1, and provided with a longitudinal slot 12, that receives a pin 13 extending from plunger 9, and constituting a stop that limits the play of the plunger.
Upon lever 7 is adjustable a finger 14, which is bent at its heel 15 around the lever, in such a manner that it may be readily moved along the same. This finger is adapted to be projected across the record 16 and is provided at its free end with a notch 17 adapted to be engaged by the stylus 18.
In use, the finger 14 is so set that its notched end 17 will be positioned directly within the innermost groove of the record. When the piece of music has been played, the stylus by striking the finger will cause the latter to turn lever 7 on its fulcrum 5, so that pusher 8 will move plunger 9 inward and thus apply brake shoe 10 to turn table 2.
When a new record is to be applied, lever 7 is swung back to carry finger 14 0E turn table 2, and plunger 9 is manually retracted within bearing 11.
By setting finger 14 nearer to or farther away from the fulcrum 5 of lever 7 the device may be readily adapted for records of difl'erent lengths.
It will be seen that my brake is simple in construction, reliable in operation, and that it may be readily applied to a phonograph without requiring any material alterations therein.
I claim:
1. A phonograph brake comprising a lever, pivoted to the phonograph casing, a finger adjustably engaging the lever and adapted to be projected across a record, and a brake shoe operatively engaged by the lever and adapted to be pushed by said lever against the record.
2. A phonograph brake comprising a lever, a finger adjustable thereon and adapted to be projected across a record, a bearing, a-
plunger slidable within the bearing and adapted to be pushed by the lever toward the record, and a brake shoe carried by the plunger.
3. A phonograph brake comprising a lever, a finger adjustable thereon and adapted to be projected across a record, a hearing, a tubular plunger slidable within the bearing and adapted to be pushed by the lever toward the record, a brake shoe fitted within the plunger, and means for limiting the axial movement of the plunger within the bearing.
MICHELANGELO BONO.
