DUNCAN R. MUVICKER, OF ST. LOUIS, MISSOURI.
BEPEATING ATTACHMENT FOR TALKING MACHINES.
Application led October 16, 1922. Serial No. 594,940.
To all whom it ma, concern:
Beit known thatl DUNCAN R. McVrcK- ER, a citizen of the nited States, residing at St. Louis Missouri, have invented a new and useful llepeating Attachment for Talking Machines, of which the following is a specification.
This invention relates to repeating attachments for talking machines, and consists in the novel construction hereinafter disclosed.
An object of the invention is to provide an attachment that may be placed upon a talking machine record arranged to cooperate with the needle of the talking machine to cause the record to repeat once, and then stop the machine.
Additional advantages of the construction i will be -apparent from the detailed description thereof taken in connection with the accompanying drawing, in which- Fig. l is a plan view illustrating the attaehment applied to a record.
Fig. 2 is a vertical section on the line 2-2 of Fig. 1.
In ythe embodiment of the invention illustrated in the drawin the attachment is shown applied to a talking machine record in association with the revoluble table l of the talking machine, said table being provided with the central spindle 2 over which the talking machine record 3 is mounted, the record resting on the table in the usual manner and being revolved therewith by the talking machine mechanism.
The attachment itself consists of a member preferably formed with a series of radial arms 4, a central connection 5 for the arms, said central connection being provided with an irregularly shaped opening 6 to adapt the attachment to reco-rds of different sizes. It will be understood, of course, that the attachment may be made solid, but it is prefer- .able to make it as illustrated so as to make it as light as possible in order that it may not interfere with the normal operation of the talking machine. The attachment itself may be made of pressed Celluloid or other suitable material.
At the outer extremity of the arms 4 is a helical shaped flange or rim 7, formed on gradually decreasing radii extending from the outer t0 the inner circumference of the grooves of the record. In this ilange or rim 1s a helical groove 8, and cut through a widened arm 9 of the attachment is an L-shaped slot 10 and an L-shaped slot `by a thimble 13l that extends 11, the slot 10 having its short arm near the axis of the attachment, and the slot 11 having its short arm near the periphery of the attachment. It will be noted that the long arm of the slot 11 is longer than the long arm of the slot 10, so that the inner extremity of the slot 11 extends within the normal inner circumference of the grooves of the record. The groove 8 connects with the kshort arm of the slot 10 at one end and with the short arm of the slot 11 at the other end.
IThe path of the needle of the talking machine is indicated arrows in Fig. 1. It
b will be understood that the talking machine is provided with the usual pivoted tone arm that supports the sound box, said sound box being provided with a reproducing needle 12. In order to connect the attachment with the talking machine record the attachment is laced on the upper face of the record and) is connected over the edge ofthe record through the extremity ofthe arm 9.
.In the operation of the device the reproducing needle is placed at the starting point 14 and travels inwardly in the slot 10 during the first reproduction of the record. After the needle has reached the inner extremity of the slot 10 it moves at an angle through the short arm of the slot and is carried into the groove 8. Continuous rotation of the table l carries the needle through the .groove 8 to the short arm of` the slot, again bringin the needle in contactwith the record. he needle then travels inwardly in the slot 11, reproducing the record for the second time. As the long arm of the slot 11 extends within the inner circumference of the record grooves the needle moves inward] suiiiciently to operate the usual stop evice of the talking machine.
I am aware that the invention may be modifie-d in certain particulars without departing from the spirit and scope thereof, and I do not limit myself to the exact details shown and described but what I claim and desire to secure by Letters Patent is 1. A device of the character described, comprising a member adapted to be placed upon and connected with a talkin machine record and having a slot for 51e initial inward travel of the talking machine needle and having a groove connected with said slot into which said needle moves from the slot, said groove being formed on gradually increasing radii to move the needle from the inner circumference to the outer circumference of the record rooves, said member having a second s ot connected with the outer end of said groove into which l the needle moves fora second reproduction of the record.
2. A/ repeating attachment for talking machines comprising a member including a central hub having an opening therein to receive the central spindle of a' talking machine record table, arms radiating from said hub and one of said arms having se arated slots therein, a helical rim supported y said 3. A device of the character described comprising a member adapted to be placed upon and connected with a talking machine record and having an angular slot for the initial inward travel of the talkin machine needle and having a groove extending from the end of one arm of said slot into which groove the needle moves from the slot, said groove extending from said slot on gradually increasing radii to move the needle from near the inner circumference to the outer circumference of the record grooves, said member having a second angular slot the end of one arm of which communicates with said groove and into which the needle moves for a second reproduction of the record, said second slot extending and terminatin inwardly beyond the inner end of the rst-named slot, and inwardly from the normal inner circumference of the record grooves.
