PHONOGRAPH.
Specication of Letters Patent.
Patented Aug. so, 191e.
A Phonographs, of which the following is a vio y10 formed therein.
spaced fingers 11 on the portion 9, one of specication.
The present invention relates to phonographs, and particularly to attachments for automatically stopping the machine when the record has been played.
One object is to provide a device of this character which is simple and eiective in operation.
Another objectis to provide 'such a device which is adapted to be readily attached to the present form of machine.
These and other objects may beattained by the construction shown in the accompanying drawings in which:
Figure l is a plan view of a phonograph machine; showing our invention applied, Fig.l 2 is a view of the invention detached from the machine, Fig. 3 isa vertical sectional view of Fig. l, on the line 3 3, Fig.
4l an elevation of the braking device, Fig..`
5 is a. sectional view on the line 5-5 of Fig. '-l, and Fig. ('is a detail view of the trip detached. c
ln the drawings 1 represents the motor of :1 phonograph machine, 2 the record carrying drinn, 3 the sound box having thelug 4, and the rider bar 5.
The invention herein contemplated is adapted for attachment to the rider bar 5.
The present device comprises the brake member 6, the trip member 7, and the )connecting link 8.
The brake member consists of the cylindrical portion 9 having a longitudinal bpre Laterally projecting which carries the adjusting screw 12,- serve as a clamp by means of which the member 6 is secured. to one end of the rider bar-5.
Sliding in the bore 10 is a plunger 13. The.. lower portion 14 of the'plunger is reduced" and protrudes through the bottom of the' member' 6, and has its extremity providedI with a milled head 15, adapted to be grasped by the fingers of the hand to the bottom of the bore and enclrcles th'e reduced end 14 thereof. The spring keeps the adju theA plunger 13. A coiled spring 16 is seatedbe-- plunger 13 at its upward limit of movement. Seated Iin a recess in the upper end of the plunger 13 is a friction block 18 of rubber, leather or other suitable material.
vA bayonet slot 19 is formed in the side of the portion 9 and directly above the upper of the clamp lingers 11.l An eye bolt 20 secured in any suitable manner as by a threaded end 29 tothe plunger 13, lies in the bayonet slot 19. l The trip member consists of the block 7 having the depending portion 22 and horizontal portion v23. The portion 23 is vertically perforated to receive'the adjusting screw 24, and transversely perforated as at 25 to receive the end' 27 of the connecting link-8. i The connecting link 8, is bent near each end transversely and forwardly atan angle so that vits ends 26' and 27 lie in a plane' parallel with the mainV portion thereof.
The end 26 -is provided'` with an -eye 28.
adapted to engage in the eye 80 of the bolt 20, andform a loose connection.
The operationof the device is as follows:
vThe brake member Gis secured to one end of the rider bar 5 by means of clamping lingers 11 and screwA 12. rThe block'i7 is placed on the opposite end of the rider bar 5 so that its horizontal portion 22 rests on the bar, andfrom the opposite endvof the ridery bar 5, to
be engaged by the lug llon the sound box 3. rilhe plunger 13 is pulled-back by means of the head 15 and turned until the bolt 2() engages in the transverse portion of the bayonet slot 19. The phonograph is started, and when the Sound box 3 reaches the end of the record thelug 4 will engage the trip block 7 and move it along the rider bar, thereby communicating.motion through the link 8 to the bolt 20. The bolt 20 will be moved in the slot 19 untilit comes o iposite the longitudinal portionV thereo 'It will thus be seen that-a very simple and'-` etective device is produced, and one which will not easily get out of repair.v .Further a The "springl will. then act on the plunger 13 zoo device is produced which can be readily attached to the rider bar of a phonograph without. any alterations in the form or construction of the machines on the market.
Having thus described the invention' what is claimed as new is:
l. The combination with a phonograph having a rider bar, of a brake member se cured at one end of said rider bar and including a trigger, a link loosely connected at one end to the trigger, and a trip block longitudinally adjustable on the link near its opposite end and loosely riding on the rider bar.
2. The combination with a phonograph having a rider. bar, oi an automatic. stop comprising a brake member having a hollow body provided with a bayonet slot, a spring pressed plunger playing in the hollow body and having a friction block on its outer end, a laterally projecting apertured thereof, an L-shaped trip member loosely engaging the rider bar near its opposite end and provided with an aperture and clamp ing screw, and a link adjustable in the aper- .ture of the trip member and having its opposite end engaging in the aperture of the said lug on the spring pressed plunger.
In testimony whereof we aiiix our signatures in presence of two witnesses. JOHN D. BOWERS. LEON MAYHUE. Witnesses:
