STYLUS GUIDING ATTACHMENT FOR SOUND-RECORDS.

Specification of Letters Ma. Pat ted Sept, 29, 1914,

Original application filed May 20, 1913. Serial No. 768,845. I Divided and 'this appllcatio n filed oct b 9 1913. Serial No. 794,307. 1

Be it known that I, CHARLES-W. EBELING,

a citizen of the United States, residing at Wheeling, in the county of Ohio and State of \Vest Virginia, have invented a new-and useful Stylus- Guiding Attachment for Sound-Records, of which the following is a specification.

The present invention relates to improvements in stylus guiding attachments for sound records, the present application being a divisional application of my co-p'ending application filed May 20, 1913, Serial No.

768,845, one object of this invention being the provision of coiiperable means, carried by the reproducerand the sound record,

whereby the stylus is held above the recordduring a portion of the revolution thereof and finally delivered into the phonic groove thereof at the proper point.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter de scribed and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed Without departing from the spirit of the invention.

In the drawings Figure 1 is a'plan view] of a disk record with the present attachment applied thereto. F ig. 2 is a side view 01. a record and reproducer with'the present at tachi'nent in use in guiding and retaining the stylus from contact with the record. Fig. 3

'1 being disposed in usual relation to the re-'- producer and stylus.

-Connected to theperiphery of the record, as clearlyillustrated, is. a segmental mem- A ber 2, provided with a track or rib 3, whose upper surface is cam-shaped so that the sty lus, as will presently appear, when the highest pointof the track 3 is engaged, Wlll beheld above the surface-"of the record, as clearly illustrated in Figs. 2 and 3, tobe deposit d in the phonic groove when the lowest point of the guiding rail or track 3 is reached.

In-order to accomplish-this, the segmental member 2 is attached at the desired point to the periphery of the disk 1, by means of the" fastening cleats 5.

The portionof the present device carried by the reproducer R, includes an attaching plate 6, attached to such reproducer by means of screws 7. fixedly by the plate 6, and is provided with a recessed and shouldered portion 9, which Asleeve 8 i s carried as will presently appear, limit-s the rotation fit upon the rib or track 3, and as clearly shown in Figs, 2 and 3, holds the reproducer R in such position, that the pointed end of the stylus-S will be elevated above the surface of the record.

A spring 16 is coiled upon the spindle 10. between the inner end'of the sleeve 8, and

' the block 12, and has .oneterminal secured .at 17'to the sleeve 8, while the other terminal is attached to the block 12,-said spring having a normal tension tozelevate the screw, 13, and the'arm 14 to thedotted line position, Fig. 2. When the forkedend 15 015 the arm 14 is'positioned upon the track orrib 3, the spring 16 is wound, but due tothe weight of the'reproducer R, the parts will assume the, position, as shown in Figs. 2- and 3, so.

that as the disk- 1 is rotated, the forked end 15 of the arm 14 will rideuponthe rib 3 and when the same has becomedisengagedtherefrom, the pointed end of, the stylus S w will be presented to'and placed at the selected point of the phonic groove of the a record. -When the arm 14 has been released, the spring 16 will move the same to the dotted line position, Fig. 2, so that the arm 15 will be out of the path of the rib or track '3, as the same again approaches the stylus and rep-roducer record.

In putting the present invention into practice, the track '3 is properly attached and due to the rotation of the adjusted relatively to the record, so that when the stylus carried by the reproducer is held above the record by means of the arm l4,-tlie rotation of the record through its platform and the consequent movement of 'the track 3 will cause the gradual lowering of the reproducer and stylus so that the point of thestylus will be presented to a selected point, orat the beginning of the phonic groove of the record. The curve of H the track 3 is parallel to the curve of the phonic groove 4E to thus insure the'proper delivery of the stylus to the phonic groove.

'a spring for swinging t e trac means out of the ath of the track after the. stylus has been p aced in the phonicv groove.

3'. The combinationxwith a sound record' What is claimed 1s; 1. The combination with a sound'record and a reproducer and stylus, of means for placing t e stylus in a selected point ofthe phonic groove of the record, including a raised track carried by the disk adjacent the periphery thereof, said track having its.

upper edge formedwith a gradual incline and upon a curve parallel to the phonic groove, and means carried by the reproducer for sliding engagement with the track to hold the stylus above the record' until gradually lowered by the inclined portion of'the.

track into the phonic groove.

2. The combination with a sound record and a reproducer and stylus, of means for placing the stylus in a selected point of the phonic groove of the record, including a raised-track carried by the disk adjacent the periphery thereof, said track having its upper edge formed with a gradual incline and upon a curve parallel to 'theiphonic groove, laterally swin fngqmeans carriediby' the reproducer for sli ing engagement with the tracktohold the stylus above the record.

until adually lowered by the inclined portion 0 the track into the honic. oove, and engaging diskand a-v jrepro'ducer and stylus, of; means for-placing the stylus in a selected-point of.

the phonic grooveof, the record disk-including a raised track, means carried thereby for attaching thetrack to the recordgjdisk adja- 4. The combination with a sound record disk and a reproducer and stylus, of means for placing the stylus in a selected point of the phonic groove of the record disk, including a raised track, means carried thereby for attaching the track to the record disk adj acent the periphery thereof, said track having its upper edge formed with a gradual incline and upon a curve parallel to the honic groove, laterally swinging means carried by the reproducer for sliding engagement with the track to hold the stylus above the record disk until gradually lowered by the inclined portion of the track into the phonic groove, and a spring for swinging'vthe track engaging means out of the path of the track after the 'stylus has been placed in the phonic groove.

5. The combination with a sound record disk and a reproducer and stylus, of means for placing the stylus in a selected point of the phonic groove of the record disk, including a curved support, means for attaching the support to the record disk, a raised track carried by the support, said track having its upper edge formed witha gradual incline and upon a curve parallel .to the phonic groove, and means carried by the reproducer for-sliding engagement with the track to hold the stylus above the record disk until gradually lowered by the inclinedportion of thetrack into the phonie-groove,-- 6.,The combination. wit a sound record disk and a reproducer and stylus, of means for placing the stylus in a selected point of thephoni'c groove of the record disk, includingfta curved support, means for attaching the support to the record disk, a raised track carried by the support, said track havin its upper edgeformed with a gradual inc ine and upon a curve parallel to the phonic groove, laterally swinging means carried by the reproducer for s1 ing engagement with the track to hold the stylus above the record disk until gradually lowered by the inclined portion of the track into'thephonic groove,

and a spring for swinging the track engagmg means out of the path of the track after the stylus has been placed in the phonic groove.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of two witnesses.

CHARLES W. EBELING.
