JULIUS ROEVER, OF NEW YORK, N. Y.

RECORD-HOLDER.

' Application filed July 22, 1910, Serial No. 573,157.

To all whom it may concern Be it known that I,JULIUs Ronvnn, of the city of New York, county of Queens, and

State of New York, have invented a new and useful Improvement in Record-Holders, of which the following is a full, clear, and exact description.

My invention relates 'to improvements in record holders for phonograph records and especially to that class of holders WhlCll are mounted on a wheel or other rotary device, so that the records can behrought into succcssive Operation. In record holders of thiskind it ha's been found difiicult to get a at the sametime structure which would permit of a record being easily Slipped on or off the holder, and permit of the record bemg easily adjusted so that the needle of the reproducer' will strike exactly in the right point of the record.

I The object of my invention is toproduce a record holder which will permita record to be instantly slipped on endwise over the holder Without the necessity of operating or adjusting any mechanism, and in which the.

record can then be accurately adjusted in of the reproducer.'*

A further object of my inventionis to produce a holder which is cheap to manufacture and simple. in constru'ction,,and one in which the friction of rotation is reduced to a minimum.

Other objects of my invention are to produce a record holder upon which a record can be easily placed or removed, and on which the ends of the record are left entirely free so that there is, no danger of breaking them, and nothing to interfere with their adjustment, and further to produce a record holder vvhichcan not only be adjusted in and out on its supports, but has a central driving spindle extending through the support, and which can be entirely removed when necessary.

Another important feature of the inven tion is this: Pu vv.ograph records are of two general kinds, known in the trade as wax records and indestructible records. The indestructible records can be carried on a skeleton holder, but the wax records cannot. l'iccause they are likely to collapse. Moreover, on record holders having a solid face, the wax records in either ve"y warm or very cold weather are likely to stick so Snecification of Letters Patent.

that they break in taking them 011'. I provide my record holder, however, with longitudinal corrugations so that it presents a good gripping surface the cylinder, but will not stick closely to the wax record, and so such records can be easily placed on or taken oil the record holder, while the holder is also as well adapted to securing a so-called'indestructible record.

Reference is to be had to the accompany ing drawings forming a part of this specification, in which similar reference characters indicate corresponding parts in all the views. Figure 1 is a longitudinal section of a record holder embodying my invention, and Fig. 2 is an end view of the holder proper.

Themcans for carrying the record holder is immaterial and forms no part of this in vention. I have, however, illustrated it as mounted on a horizontal disk 10. The record, holder is supported by the post 11 which may be secured to the disk 10 or integral therewith. This post 11 terminates at its upper end in a horizontal casing 12. The record holder 13 is supported by the shaft or spindle 14 which is preferably integral therewith, and which "extends through the sleeve 15, which sleeve is supported within the casing 12. The sleeve '15 is screw threaded at each end to receive the collars 1G and 17. These collars are beveled at their inner ends and when screwed onto the ends of the sleeve 15, form cones for ball bearings. Bearing cups l8 and 18 are supported rigidly within the casing 12 and are adapted not to contact with the sleeve 15, these cups 18 and 18" togeher with the cones 16 and 17, forming hearings for the balls 19.

The record holder proper 13 is in the form of a shell slightly larger in circumfercnce at its inner end, and has its outer surface longitudinally corrugated as shown at 13 in Fig. '2, and is adapted to fit snugly against the inner surface of a phonographic record. The shell 13 is closed at its outer end, and has for convenience a handle 20 by which theholder 13 and the shaft 14 may be adjusted longitudinally in relation to the sleeve 15. The shaft 14 is movablev longitudinally through the sleeve 15, but is turnable therewith, and to this end I proto the inner Wall of vide a keyway 21 in the sleeve 15 and a key 21 upon the shaft 14. The collar 17 is elongated at its outer end forming a sleeve 22 upon which is mounted the friction disk 23 which is supported rigidly upon the sleeve 22 against the shoulder of the collar 17. The friction disk 23 may be rotated in any desired way. I have not shown means for rotating it, as such means form no part of the present invention. It is apparent, therefore, that when the friction disk 23 is rotated, the collar 17 together with the sleeve 15 and the shaft 14 will rr iate with it within the casing 12 on the ball bearings provided therein. I thus provide a record holder which will rotate With a minimum of friction and also very smoothly and accurately, and on Whichthe record may be adjusted very nicely in relation to the stylus of the reproducer.

It will be seen that one can grasp the handle 20 and not only adjust the record in and out on its support, but can pull the spindle or shaft 14 entirely out if desired, and if necessary to do any work on the record or other parts. This is often a great advantage.

I claim 2-- 1. A record holder comprising a horizontally arranged cylindrical casing, a sleeve held to rotate in the casing, a collar on the sleeve projecting from the end of the casing and carrying driving means, and a shell or mandrel open at its inner end and closed at its outer end, said shell or mandrel having a rigid internal spindle sliding freely in and removable from the aforesaid sleeve, but arranged to turn with the sleeve.

2. A record holder comprising a horizontally arranged casing, a sleeve turning in suitable bearings within the casing, meam for driving the sleeve, and a shell or mandrel adapted to support a record, said shell or mandrel being open at one end, closed at the other, provided with a handle at its closed end, and having a rigid spindle arranged longitudinally Within it, said spindle being freely movable in the aforesaid sleeve and detachable therefrom, and also arranged to turn with the sleeve.
