Specification of Letters Patent.

Patented July 11.9, 1921..

Application filed October 1, 1920. Serial No. 413,989.

To all whom it may concern:

Be it known that I, GEORGE F. VorrH, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Repeating Devices for Talking-Machines, of which the following is a speclfication.

One object of my present invention is to provide a repeating device of the same general character as that disclosed in my U. S. Patents, N os.'1,248,0 l1 of Nov. 27, 1917, and 1,349,240 of Aug. 10, 1920, which will in clude improved means for controlling the transfer of the reproducing element of a talking machine so that said reproducing element may be quickly transferred from one playing groove of a record to another playing groove so that the device is particularly useful for playing dance music where no extended interruption of the playing is desired even though the record is not completely reproduced for. each repeating action of the device.

Another object is to provide means whereby the device will remain in operative position upon the center post of the turntable even though said center post is exceptionally short and does not protrude far beyond the surface of the record.

Another object is to make my invention of a simple yet durable construction which can be qulckly and easily manufactured.

These objects, and other advantageous ends which will be described hereinafter, l attain in the following manner, reference being had to the accompanying drawings in which- Figure 1 is a top plan view of a repeating device made in accordance with my present invention,

2 is a fragmentary elevation looking in direction of the arrow w in Fig. 1 and drawn on an enlarged scale,

Fig. 3 is an enlarged fragmentary section taken on the line 33 of Fig. 1,

Fig. 4.- is a fragmentary perspective view showing certain the needle controlling elements in an inverted position,

Fig. 5 is a fragmentary top plan view showing a slight modification of certain of the parts illustrated in Fig. 1 and 6 is a fragmentary'top plan view showing a slight modification of the which connect with the center post of the turntable.

Referring to the drawings and particularly to Figs. 1 to 4 inclusive, my improved repeating device includes a plate 7 having a hole 8 therein through which the center post of a talking machine is adapted to project and I preferably provide a disk 9 having a hole 10 (see Fig. 3) in register with the hole '8. The disk 9 has upwardly projecting hooked arms 11 which freely pass through slots 12 in the plate 7 so that while the hooked arms connect the disk 9 to the plate 7 they will permit the plate 7 to tilt slightly, for reasons hereinafter obvious, without completely detaching the device from the center post which passes upwardly through the holes 10 and 8; it being noted that even though the plate 7 tilts, the disk 9 will remain fiat upon the record so that if the post is short and the plate 7 tilts to a position above the top of the post, the post will still remain in the hole 10 of the disk 9. The slots 12 are made sufficiently large to permit this tilting action.

The plate 7 supports a number of guide rails 13 which are preferably made in the form of partial spirals and these guide rails are made in the same manner and for the same purpose as disclosed in my above mentioned patents; the rails being operative to be engaged by any part such as 26 which is connected to the sound box and which is capable of spanning or bridging the upper edges of said rails so that the rails will move the sound box in a direction away from the center of the record toward the initial playing grooves of the record. An arm 14 of the plate 7 has portions 15 which embrace a casing 16; said casing forming a guideway fe l a flattened tube 17 which extends inwardly and at its innermost portion is provided with a beveled end surface 18. This tube 17 has a wire 18 secured therein provided with points 19 as clearly shown in Figs. 2 and said points 19 being the grooves of the record and during the rotation of the record will, due to their engagement with the grooves of the record, automatically slide the tube 1i" toward the center of the record until the points 19 reach the innermost groove of the record and thereby stop further inward movement of the tube These points 19 made comadapted to engage into will hereinafter eled surface 22 extending at a slant away from the edge 23 of the casing 16; said casing 16 is cut away at a slant as shown at 24 and it will be noted that during the playing of a record, a part of the sound box or reproducing element will be engaged by the edge 23 of the casing and as the record is played, the sound box and cooperating parts will move along the edge 23 onto the edge 25 of the tube 17 and then in engagement with the beveled surface 18 and the pressure exerted against said surface 18 will cause the flattened tube 17 to be moved outwardly to free the reproducing parts, after which the entire device will rotate with the record and the part 26 will be engaged and lifted by the end portions 27 of the rails 13 in the same manner as described in connection with my above mentioned patents and the sound box and reproducing elements will be moved by said rails in a direction away from the center of the record and since the buffer 20 is in line with the ends 21 of the rails 13, the buffer 20 will be engaged initially by said reprodu cing parts as they leave the control of the rails 13 and the beveled end of the buffer will be bent so as to,permit the reproducing parts to again engage the edge 23 to again cause the playing of the record. The beveled surface 18 is preferably made at such angle that when the reproducing element engages it to push the tube 17 outward, the reproducing portion of the sound box will still be in one of the playing grooves of the record. During the outward movement of the flattened tube 17 due to the engagement of the reproducing elements with the edge 18, the points 19 will be automatically pulled out of the grooves immediately adjacent the inner part of the record and in this manner the reproducing needle of the talking machine will release the de vice before the record. has been entirely played. In order to insure that the recordengagin t reproducing element is transferred outward y to a playing groove of the record. I provide a switch 28 w ich is pivoted at 29 on the arm 19; said switch being adapted to be manually moved on its pivot to bring its end 5G into engagement with the outer rail and cause said outer rail to be bent slightly inward and thus deflect the record-- engaging reproducing element to any one of the outer playing grooves of the record.

Fig. 5 in dotted lines shows the switch 28 having been moved into such position.

It will be understood that the flattened tube 17 is freely slidable within the casing 16; the parts being made of such material as will not cause great friction therebetween. In other words it requires a very slight push of the flattened tube to slide the same within the casing. The only friction which must be overcome is the friction caused by the points 19 in being moved laterally across the grooves of the record. In actual practiee 1 have found that a device constructed as above described when placed upon a record will automaticall cause the movement of the tube 17 inwar ly due to the engagement of the points 19 in the grooves of the record and that when the reproducing parts or part of the talking machine engages the beveled surface 18 that the tube 17 will be slid outwardly to release itself from said reproducing element and the repeating action will take place just before the record has been completely played. If it is desired to completely play a record the switch 28 can be moved into its normal position as shown in Fig. 1 and a slide strip 31 within the tube 17 can be moved outwardly so that its end 32 will project beyond the beveled surface 18. When this action occurs the device will not be released from the reproducing parts until the reproducing parts have passed beyond the outer end 32 of the strip 31 after which the device will be released and will rotate with the record to cause the groove-engaging reproducing element to be transferred again to an outer groove of the record. After the rotation of the device it will engage the reproducing portion of the machine as above specified and the rotation of the device will be stopped. This stopping action may cause a slight tilting of the device but in view of the provision of the disk 9 as above described, this tilting action will not be suf- 11o ficient to release the device from the center post even though the center post does not project far above the record.

1n Fi 5 I have illustrated a construction in whici the casing and flattened tube is 115 eliminated and I have substituted a single slide strip 31 which is slidably connected to the arm 1-1 and it will be noted that with this construction the reproducing portions of the talking machine will be engaged by 120 the strip 31 and after said reproducin portions have freed the outer end 33 of said strip 31 the device will operate to repeat in the same manner as above described.

In Fig. 6 I have illustrated a construction 125 in which the plate 7 instead of a single hole 8 may be provided i a slot having individually curved s 8 arranged side by side, each of wt capabie of re-' ceiving the center post of a talking machine 130 turntable so that the same device can be used for records of different sizes. In all other respects the construction shown in Fig.

6 is similar to that described in connection with the previously described figures and I have given similar arts corresponding reference numerals. owever, it will be understood that if desired the disk 9 can be omitted in all the forms of my present invention where the turntable central post protrudes far enough to permit a slight tilting of the device without detaching itself from the plate 7 It will of course be understood that if the disk 9 is used in connection with the slot 34 that it will have registering curved portions with the parts 8 above described.

While I have described my invention as taking a particular form, it will be understood that the various parts of my invention may be changed without departing from the spirit thereof, and hence I do not limit myself to the precise construction set forth, but consider that I am at liberty to make such changes and alterations as fairly come within the scope of the appended claims.
