STYLUS GUIDING DEVICE. APPLICATION HLED NOV. 20. 91s

1,803,9GQ. Patented May 20, 1919.

5] vwe wtoz STYLUS-GUIDING DEVICE.

T0 (ZZZ whom it may concern Be it known that I, HARRY HORN, a citizen of the United States, residing in the city of Brooklyn, county of Kings, and State of New York, have invented a certa n new and useful Stylus-Guiding Device, of which the following is a specification.

It is well recognized that there is a great deal of breakage in phonograph records, owing to carelessness or inexperience in placing the stylus in tracking relation to the record, the breakage being due to the fact, mainly, that the reproducer and tone arm are allowed to drop on to the edge of the record with such force that the recorf. is either seriously scratched or broken. In

either event, the loss is a very substantial 1 one, yet, so far as applicant lmeans of the type herein under is aware, no consideration has been devised to obviate the breakage or injury adverted to.

The present invention overcomes the disadvantages specified and others, and provides in a simple, efficient and economical manner, a means wherein it is practically impossible to injure or break a record.

Speaking generally, the invention, from a structural standpoint, embodies a member, preferably mounted on the topof the phonograph cabinet, adapt-ed to cooperate with the stylus and record in such manner that when the stylus is placed thereon it may be moved laterally into tracking position on the record in such manner as to preclude all danger of sc atching or breaking the record.

From a more specific standpoint, the invention embodies a stylus supporting member adapted to be screwed into or otherwise mounted on the top of the phonograph cabinet, in such lateral and vertical proximities to the record or its support, that when the stylus is placed thereon it may be moved toward the record, arm or otherwise, in such manner that it is brought into gentle engagement with the record and automatically assumes the proper tracking position.

Features of the invention other than those specified, will be apparent from the hereinafter detailed description taken in conjunction with the accompanying drawings.

In the accompanying drawings, '1 have illustrated one practical form of the invention but the construction shown therein is to be understood as illustrative, only, and not as defining the limits of the invention.

Specification of Letters Patent.

by taking hold of the tone Patented May 20, 1919.

' Application filed Ii'ovember 20, 1918. Serial No. 263,283.

Referring to the drawings,

tive. with the device of this invention mounted on the cabinet; and

Fig. 2 shows a fragmentary section of a phonograph, with the device of this invention shown in cooperative relation with the stylus and reproducer; and

"Fig. 3 shows a fragmentary perspective view of the device of this invention.

Referring to .the drawings, 1 is the top of a phonograph cabinet, 9. the record holder, 3 the record, 4: the tone arm, 5 the reproducer, 6 the stylus and 7 the device of this invention, as a whole.

The particular form of the invention shown, embodies a screw, screwed into the top of the phonograph, as shown at 8, and having a top 9, preferably composed of glass, porcelain or other suitable hard material. The top member 9 is preferably provided with a groove 10, and the same is preferably inclined, as shown, so that the stylus will readily slide down the inclined path thus formed. The stylus supporting member is so positionel that the inner edge of the head 9 is substantially in vertical alinement with the outer groove of the record, although the inner edge may be positioned intermediate the outer circumference of the record and the groove, as, in either event, it will assume a proper position in the groove. lVith regard to its vertical position, the screw is so adjusted that the bottom well of the groove is so slightly above the record, as to be substantially flush therewith. Only sufficient space need be left to permit of inserting a record thereunder, although a fall of the stylus on to the record of a sixteenth of an inch, or slightly more, would not, ordinarily, injure the record. In practice the device, and particularly the incline or track 10, is usually made of a color contra-sting with the color of the record whereby said device may be more readily located when it is desired to move the stylus to inoperative position.

From the foregoing description, the operation of the invention will be readily understood, but it may be briefly described as follows: A record having been placed in position on the holder, all the operator need do is to swing the tone arm into such position that the stylus 6 ispositioned within the groove 10, whereupon, a slight lateral movement causes the stylus to gently engage the record and cause, it to automatically assume its proper tracking positlon thereon.

It, will be understood that the invention may partake of various forms, both as to the construction of the top member 9 and as to the manner of mounting the stylus support with reference to its cooperating parts, without departing from the scope of the invention, the scope of which is commensurate with the appended claims.

What I claim as new and desire to secure by Letters Patent is:

1. In a phonograph, a stylus supporting device mounted in normally fixed position adjacent the edge of a relatively rotatable record, and adaptedto partially overlie said record, whereby, When the stylus is posi tioned thereon, it may be moved therefrom into su'l'istantially correct tracking on the record. 7

2. In a phonograph, a rotatable record, a stylus supporting device independent of the record for support and mounted to normally remain stationary While the record rotates, said device being provided with an inclined guide-way in which the stylus is adapted to be supported when oil the record,

position said guide-way overlying a portion of the record and terminating adjacent the outer sound groove thereof, whereby said stylus may 'be moved down the guide-way into cor rect tracking positionon the record.

In testimony whereof, I have signed my name to this specification.

' HARRY HORN.'
