REPEATlNG lVlECi-iANlSlt l FOR PHONOGRAPHS.
SPECIFZCATIGN forming part of Letters Patent No. 695,272, dated March 11, 1902. Application filed November 5, 1901. Serial No. 81,176. (No model.)
To aZZ whom, it may concern:
Be it known that I, JOHN JAKOB BILLI'NG, a
citizen of the United States, residing at Philaof Philadelphia and delphia, in the county State of Pennsylvania, have invented a new and useful Repeating Mechanism for Grap'hophones, of which the following is a specification.
My invention relates to repeating mechanism for graphophones, my object being to provide automatic means for returning the needle after it has traversed the record back to the initial position.
Referring to the drawings, Figure 1 is a plan view of my device in the initial position that is, the beginning of the record. Fig. 2 is a side View of same. of same. Fig. of the shoe.
Similar numerals refer to similar parts throughout the several views.
1 represents the revolving record-table, the record-score being in a horizontal plan and in a spiral from the outer circumference toward the-center. The arm 2, carrying the reproducer 3 and needle 4:, is pivoted on a horizontal pivot 5 to post 6, which is in turn pivoted vertically at 7 to bracket 8, so that as the record-table 1 travels in the direction shown by the arrow in Fig. 1 the needle 4- is carried toward the center of the table to the end of the record-score. At the end of therecordscore a continuing-groove 9 is provided in the surface of the record-table having an accentuated spiral which serves to carry the needle to the position toward the center of the table in Which the point 10 of the extension 11 from the reproducer 3 cooperates with an inclined spiral groove 12 in post 13, which is rigidly secured to the record-table and adapted to rotate with it. This serves to raise the reproducer and needle out of engagement with the record-table. The groove 12 then extends outwardly along the arm 1% for the purpose hereinafter described. By the gearwheels 15 and 16 beneath the record-table 1 motion is communicated from the drivingshaft 17 to the horizontal shaft 18, which terminates in an attenuated shaft 19. Secured to the arm 2, about midway its extremities, is the downwardly-extending member 20, car rying at its lower extremityan approximately 4 is a detail, slightly enlarged,
Fig. 3 is an end viewhorizontal extension or shoe 21, having a laterally-extending offsetfrom the plane of the part 20 toward the revolving table and provided at its under side with a suitable surface 22, such as rubber or leather, forfrictional contact with the revolving shaft 19.
Referring to Fig. 2, it will be seen that when the needle is in the operative position in engagementwith the record the lateral extension of the shoe 21 lies beneath the shaft 19 and travels entirely beneath said shaft 19 prior to the engagement of projection 10 with spiral incline groove 12. It is then raised bythis spiral incline 12, the arm being raised, as above described, lifting the needle above the record and carrying the shoe 21 to an elevation above therevolvingshaft19. The point 10 then traveling along the groove 12 is carried outwardly to the end of the extension 14. This reverses the horizontal movement ofthe arm 2, so that when the point 10 leaves the groove 12 at the end of projection 14 the laterally-extending part of the shoe 21 is resting upon the revolving shaft 19, which by its frictional engagement with the surface 22 of projection 21 carries the arm hack gradually to the initial position, so that when the extension 21 leaves the shaft 19, as shown in Fig. 1, the needle has been bronghtintoa position to engage with the beginning of the record, the incline of projection 21 being nicely adjusted, so as to deliver the needle back to the record without unnecessary impact. A stop 23, preferably of incline resilient material, may be provided to positively limit the retu in movement of said needle and then permit it to slide quietly into position.
What I claim is-- 1. In a repeating mechanism for graphophones a lifting deviceprovided witha spiral incline groove rotatable with the record-table and a projection connected with the reproducer adapted to engage in said spiral incline groove for lifting the reproducer-needle from engagement with the record-table.
2. In a repeating mechanism for graphophones a centrally-located projection from the record-table provided with a spiral incline groove, said groove first contracting and then expanding, and a projection connected with the reproducer adapted to engage with said groove to lift the reproducer-noedlo from engagement with the recordtable and reverse the horizontal movement of said reproducer.
8. In a repeating mechanism for graphophones a centrally-located projection from the record-table providedwith a spiral incline groove, said groove first contracting then expanding, a projection connected with the reprodncer adapted to engage with said groove to lift the reproducer-needle from engagement with the record-table and reverse the horizontal movement of said reprodncer, and frictional means for carrying the reproducer back to the initial position after it leaves said spiral incline groove.
4. In a repeating mechanism for graphophones the combination of a spiral groove is the record-table for cooperating with the needle to continue the movement of the reproducer toward the center of the record-table, a centrally-located post rotatable with the record-table provided with a spiral groove first ascending and contracting then expanding horizontally, a projection connected with the reproducer adapted to engage with said groove to lift the reprodncer from the recordtable and change its direction of motion, a shoe connected with the reproducer-supporting means and a rotatable shaft adapted to cooperate with the shoe to complete the return movement of the reproducer to the initial position.
5. In a repeating mechanism for graphophones the combination of a lifting device provided with a spiral incline contracting and expanding groove centrally located and rotatable with the record-table, a projection connected with the reprodncer for cooperating with said groove a rotatable shaft and an arm connected with the reprodncer-supporting means having frictional engagement with'the rotatable shaft.
6. In a graphophone having a horizontal plane-surface record-table, a spirally-grooved post centrally disposed and rotatable with said table, said spiral groove first contracting then expanding, a reproducer-supporting arm, a projection connected therewith to cooperate with the spiral groove, a rotatable shaft and means for communicating motion thereto in connection with the movement of the table and a member connected with the reproducer-supporting arm having frictional engagement with the rotatable shaft after the disengagement of the cooperating projection and spiral groove, substantially as described.
'7. In a repeating mechanism for graphophones a rotatable shaft driven by the record-driving mechanism, a friction-shoe connected to the reproducer-supporting arm to cooperate with said rotatable shaft and automatic means for lifting the reproducer out of engagement with the record-table and for carrying the friction-shoe into cooperation with the rotatable shaft.
8. In a repeating mechanism for graphophones a rotatable shaft driven by the recorddriving mechanism, afriction-shoe connected to the reprodncer supporting arm to cooperate with said rotatable shaft and automatic means for lifting the reproducer out of en- 'gagement with the record-table and for carrying the friction-shoe into cooperation with the rotatable shaft, and an inclined resilient stop to limit the return movement of the reproducer and to guide it into the initial position.
