To all whom it may concern:

Be it known that I, Lnsmr.

States,

citizen of the United A. BROWN, a and a resldent of Bedtord, in the county of Lawrence and State of Indiana, have and useful Invention which.the following is -made acertain new 1n Phonographs, of

a description.

This invention relates to phonographs of the type in which a traveling carriage. carrying a reproducer. styl my invention is a rotating record cylinder,

chiefly to provide efiicient us is fed axially past and the object of In my preferred construction, mg mechanism of' the phonograph is the operatstopped by the action of the traveling carriage in unlatching the end gate of the machine when the end of the record is reached,

or at someother 'de point, the

sired predetermined machine being automatically started when the end gate is closed, which would in practice, record has been gnserte of course, be after a new d on the mandrel.

' -More broadly,-my invention comprises efli-- ci'ent means for starting and stopping the operating -mechanism 0 preventing slipping of of the phonograph without regard to the end My invention also comprises means gate. V for the record when in place upon the mandre Other objects I proved details of tions of elements are Attention is hereby panying drawings, to

the provision of imconstruction and combi'na as described and claimed in the following specification and claims.

directed to the accom-. rming part of this specification,-and in which- Figure 1 represents a side elevation of a phonograph equipped Fig. 2

with my invention;' is a plan view of one end of the phonograph showing my improved starting and stopping means; Fig. 3 1s a detail view showing the tripping means carried by the traveling carriage; and

Fig. 1 is a view of the rotating mandrel showing my improved anti-slipping device attached thereto.

The same reference various vie'ws.

characters will be 'used to denote corresponding parts in the Referring to the drawings, the standards 2 rising from the. bed-pl for the rotating mandrel parts. The rotating record 4 is mounted as ate 1 carry bearings and other rotating mandrel 3 carrying by centers 5 in beara ing 6 at the left i 9 and carries the spring spring 19 will be put under tension.

reaches the end draw the starting viewed in Fig. 1, and in bearing? carried by end gate 8 at the right hand end of the machine. End gate 8 is pivoted or hinged at latch 10, which is adapted to latch the end gate in closed position, spring 10 carrying a lug 11,,which is adapted to co-act with the 'top of post 12 formed on'the end of straight edge 13. The end of spring 10 extends above the top of straight edge 13 into the pathot the camshaped lug 11 carried by the arm 15 of traveling carriage 16 straight edge 13. This cam 14 rides under the end of spring latch 10 when the reproducer stylus reaches the end of the record to lift the lug 11 of the latch out of contact with the top of post 12. Thereupon end gate.

thrown open by a spring S is immediately 17, which is coiled around the pivot-a1 stud 9 of the end gate, one end of the same being secured .to the end gate so that the said the end gate spring constantly tends to force to anopn position.

The starting to the spiral spring 19, the other end of which is secured as by the screw .20 to the post 12. Also secured to the startinglever '18 is the rod or link 21,-the opposite end of which extends through the hole or passageway 22 in the post 12, which guides the rod 21, the end of the said rod contacting the surface'23 of the-end gate whenr'the hand end of the machine asand riding on top of the lever 18 has connected there latter is latchedkin closed position. The

rod 21 is of such a length that when the end gate is closed and the. end of rod 21 is in contact therewith, as shown in Fig. 1 of the drawings, the starting be forced to its operating position, tor then being allowed to rotate the mandrel and feed of the same. Also", by this movement of the starting lever 18 to running position, the When the traveling carriage 16 of the record, the lug 1 1 will trip the latch 10, whereupon the end gate will fly open, the rod 21 will slip through the passage way 22 in' the post- 12 and the spring 19 will lever 18 to the right, stopping the machine. When a new record has been placed upon the mandrel, or when it is desired to again start the machine the end gate 8 willbe closed, the surface 23 of the same forcing the rod 21 to the left, as shown lever 18 will the mo the traveling carriage axially in l of the drawings, and again starting the motor.

My invention also comprises an anti-slipping device, as stated. This consists of a narrow strip of silk or other ribbon 24, which is secured firmly to the mandrel 3 longitudinally of the same as by means of nected t 25 whlch are secured tol -gate when closed, the rod being of such small brass clamps the two ends of the mandrel as by screws. The provision of the silk or other friction surface on the metal mandrel prevents all possibility of the slipping of records while the machine is in operation.

It is, of course, obvious that various changes may be made in the details of my invent-ion without departing from the spirit thereof; and I wish, therefore, notto be limited to the exact structure shown and described.

hat I claim as new and desire to proteot by Letters Patent of the United States is as follows 1- 1. In a phonograph, the combination with the starting lever and the reproducer carriage, of a hinged gate, means for latching the gate closed, means for autonnitically opening the gate when the carriage reaches the end ot the record, and connections for actuating the startinglever with the closing and opening of the gate, substantially as described. g 2. In a phonograph, the combination with the starting lever and the reprodneer carriage, of a hinged gate, means for latching the gate closed, means carried by the carriage for automatically opening the gate at a predetermined point in the travel of the carriage, and means connected with the starting lever for actuating the said lever in one direction or the other, operated by the closing and opening of said gate, substantially as described.

3. In a phonograph, the combination with the starting lever and the reproducer carriage, of a stationary member, a hinged gate and means for latching the same in closed position, a spring connecting the starting lever with the stationary member, a rod con- 0 the said lever and abutting the length as to force the lever to running position and tension the said spring when so abutting the gate, and means carried by the carriage tor nnlatching the gate, substantially as described.

4. In a phonograph, the combination with the reproducer carriage, of a hinged gate, means for latching the gate closed, means tending to open the gate, and means carried by the carriage for automatically releasing said latching means to permit said second named means to open the gate, substantially as described.

5. In a phonograph, the combination with the starting member and the reprodueer carriage, of a stationary member, a stylus memher, a hinged gate, meansv for latching the same in closed position, and means tending to open the same, yielding means connecting the starting member with the stationary member, a rod connected to said starting member, the said rod being movable by said gate to force the lever to running position and to tension said yielding means, and means carried by the carriage for nnlatching the gate to permit the same to be opened by said second named means, substantially as described.

This specification signed and witnessed this 29th day of March, 1909.
