To alwhom it may concern:

Beit known that I, JUIJUS RoEvnR,-of the city of New York county of 'Kingsg and State of New Yor have invented a new and useful in'iprovement in Record-Holders, of which the following is a full, clear, and exact description.

My invention relates to improvement in record holders `for phonograph records.-

These come in cylindrical form, and my invention relates es ecially to that-class of holders which hol a series of records on a wheel or other rotary device so that the records can be brought into successive operation. In record holders of this kind it has been found diiiicult to get a structure which would permit a record to be easily slipped on or removed, and which would hold the record lightly yet securely and permit it to be easily adjusted so that the needle of the machine will strike exactly the right point. Most record holders have devices which while entering the record, also grip the ends of it, and these are objectionable because they do not allow sufficiently for the contraction and expansion, and they are awkward to handle and manage.

The object of my invention is toproduce a simple form of record holder which is cheap, and to which a record can be easily applied, and further to produce a record lholder which will hold the record in a manner to permit it to be adjusted with the utmost nicety, which will not interfere with the contraction and expansion of the record, and which will have no parts gripping the ends ot the record.

Another object ot my invention, and the main object in fact, is to produce a satislfactory record holder which will permit a record to be instantly slipped on endwise over the holder, without the necessity of adjusting or operating any mechanism. 1n my invention the only part that touches the end of the record is a light finger connected with a tension spring, and this touches merely one point on one end of the record.

v tteterence is to be had to the accompanying drawings forming a part of this invention, in which similar reference characters indicate corresponding parts in all the views.

Figure l is a longitudinal section of a record holder embodying my invention,

showing a record thereon and showing the' holder vattached to a" mac ine. Fig. 2 isa cross section on the line 2-2 ot Fig. 1 through the record holder the record being removed. F 3 is an end view of the record holder with the record thereon. Fig. 4: is a broken longitudinal section of a slightly modified form ofI record holder, and 5 is a cross section on the line 5-5 of Fig. 4.

The means for carrying the record holder is immaterial Iand* forms no part ofthe invention. Tn order that the invention may be understooch however, l haveillustrated a wheel having spokes 10, each of which has a bearing sleeve 11 arranged "parallel with the axis of the wheel, and in this is held a shaft or spindle 12 having cones 13 and 14 thereon which form parts of the ball bearings 15 and 15a. At one end the shaft has also a friction wheel 16 to drive it, but any form of rotary supporty can be substituted for the wheelv spokes 10, any desirable bearings can beV used for carrying the shaft 12, and any preferred means can be employed for driving the shaft witho'ut in the least ad'eeti'ng the principle of my invention.

The record holder proper is carried on the shaft or spindle 12, and it comprisesan elongated hub or sleeve 17 having radial spokes 17, and longitudinal ribs 18 at the ends of the spokes, these ribs being spaced apart so that they will ht snugly against the inner wall of a record 19, and the parts 17, 17a and 18 thus form a spider lwhich can be slightly smaller `in cross section at one end than at the other,'so that the record 19 which hase similar inner conformation, can be readily slipped on the spider and will be frictionally held by the ribs 18. Ubviously there can be any desired .number of these ribs 18 yand corresponding spokes 17a, and in Fig. 2 1 have shown four such parts, and in Fig. 5, three. For convenience the spider of the record holder has at the outer end a handle 20 which can conveniently bein the form of a milled "wheel as.

shown, and by this the spider can be moved longitudinally. The spider is easily adjustablelengthwise on the shaft 12, but it must also stay in the lace where it is tinted, and T use a spring ra for this purpose, which is preferably in t e form of a late sprin 21 attached to the inner end ot the hub 1 and the shaft 12 extends through the spring. The spring has' outwardly extending curved arms 22 which have a tendency to come together. and which thus grip frictionally the shaft 12, but the ends of the spring arms 22 are curved outward so that t e spider can be readily pushed on 'the shaft. Obviously the particular vconstruction of the spring drag or friction device can be changed without affectingthe principle of the invention, although I claim the structure of it as shown, Aand prefer this arrangement.

It is sometimes necessary to provide a nicer ad'ustment of the record 19 on the holder t an is afforded by simply pushingit upon' the holder as already de-l scribed, and to this end I use the following device. A light rod 23 `extends longitudinally through the spokes 17 of the spider, and at its outer end the rod is curved to give it a spring action as shown at 24, and it terminates in a light finger 25 which presses against the outerend of the cylinder or record L9. The inner end of the rod 23 connects by a light tension spring 26 with one of the ribs 18 of the record holding spider, and the connection can be conveniently made by having a` lug 27 on the rib. lt will be seen that after the record is placed on the recordholder, it can be nicely adjusted thereon by moving it one Way or the other against the tension of the spring 26, and this tension is so light that it will not of itself move the record when the latter is adjusted. When the-record'is to be removed, the finger 25 is turned over to the position shown by dotted lines in Fig. 3.

ln Figs. 4 and 5 l have shown this adjusting device on the record holder ina manner Which will permit of a rather nicer adjust-- ment, and in which the tendency .of the spring 26 to slightly shift the adjustment is split sleeve 29 which is supported on a shortV spoke 17b of the record holder, and the rod 23a which corresponds vto the rod 23 already described, is moved in and lout in this split or. friction sleeve. For' convenience the rod is provided with a handle 28 which can be a milled wheel..- Near thev outer end of the rod 23EL is a coiled spring 30, preferably doubled, and this has a terminal finger 31 which enga es lthe endof the record 19, and like the ger 25, the finger 31 can be turned over with the rod 23a so as to clear the record 19 when the latter is to be pushed on and o.

From the foregoing description it will be seen that when the'engaging finger of the adjusting device is simply turned to one side, the record 19 can be readily slipped on I and off the record holder, that the record holder as a whole can be instantly and nicely adjusted by simply grasping the handle 20 and moving it in or out on its spindle 12, and that a still nicer adjustment can be effected by moving the record on the record holder. Further, that the spring fingers 25 or B1 serve to hold the record against any displacement, and that the ends of the record are left entirely clear except for. the

4the walls of a record, a frictiondevice securing the sleeve slidablyV on the shaft, and

lan auxiliary yielding tension device arranged longitudinally of the spider and engaging one end of the record.

2. A record holder comprising a supporting shaft, a rigid spider having ribs to engage the Wall of a record, and a sleeve to slide on the shaft, a friction spring secured to the spider and engaging the shaft, a sliding tension rod mounted on the spider and engagin one end of the record, and a spring having ess tension than the first mentioned spring connecting the tension rod with the spider.

3. A record holder, comprising a supporting shaft, a rigid spider longitudinally movable thereon, and 1n frictional engagement therewith, said spider being adapted to engage the inner wall'of| a cylindrical record, l

and a s rin -pressed tension rod arranged longitu inal y in the spider and adapted to turn on its axis, said rod having a finger to engage the end of a record.
