PHONOGRAPH-DISK HOLDER.

Specication of Letters Patent.

Patented Feb. 22, 191e.

Appncation filed August 3, 1.915. Serial No. 43,458.

T 0 all whom t may concern:

Be it known that we, LEANDER E.W1L-

'KINsoN and JOSEPH M. PEIRCE, citizens of Phonograph Disk-Holder, of which the foll lowing is a specification. y

This invention relates to a phonograph disk-holder and. more particularly to the type of holder shown and described in the patent to Mitchell, No. 895,655, gust 11, 1908. A

It is the general object of our invention to improve the construction of thev disk-holder shown in the Mitchell patent with increased economy of manufacture and eiiiciency in operation.- p

Vith this general object in view, one feature of our inventionrelates to improvements in the supporting` structure by which we simplify the assembling of the disk-holdf ing levers within the inclosing casing.4 With this improved construction no longitudinal movement of any of the parts within the casing is necessary when inserting or removing .the partsf therefrom.

Further features of our invention relate to .improvements in the construction ofthelevers themselves and to certain' arrange4u ments and combinations of parts which will be lierinafter described and more particu.- larly pointed out in the appended claims.

A preferred forni of our invention. is shown in the drawings, in which- Y Figure 1 is a front elevation of the casing, a portion thereof being broken away to show the parts inclosed thereby; Fig. 2'is a sec'-` tional side elevation taken along the line 2-2 in Fig. 1 but showing the 1door in raised position; Fig. 3 is a right-hand side elevation of one of the supporting brackets;'Fig. 4 is a detail side elevation of a portion of one or' the disk-holding levers; Fig. 5 is an end elevation of a portion of one of thelevers looking in-the direction ofthe arrow 5 .in Fig. 4; and Fig. 6 is a detail sectional plan view taken along the line 6f6 in Fig. 2.

Referring to the drawings, We have shown our phonograph disk-holder as mounted within a casing 10 provided with a handle 1l and having a door 12 provided with lprof jecting pins l13---13 slidable in grooves 14E-14: formed in the side walls of the casing 10 near the upper ends thereof. Stops 15-15 issued Aui are secured to the side Walls and serve to retain the open door in .raised position. v

The phonograph disks D are each' supported in pivoted curved levers 16 grooved 1n their upper'faces to receive the disks and substantially conforming in curvature to the 'contour of the disk. In the preferred form, each lever is formed of a single 'piece of sheet metal pressed into the requisite curved outline and Vprovided with a deep groove upon its inner or upper surface.

N earl the central portion of eachlever, a Vprojection or lug 17 is secured to. the'lever vand 1s provlded with a transversely-extending opening 18. As 'shown in the drawings, the proJection 17 is also formed of sheet metal and 1s pressed into a U-shaped section,

being solderedor' otherwise secured atrits upper end to the lever 16.

The levers 16 are pivotally Supported upon a rod 19 extending through the several openings 18 inthe projections 17 and acting asa pivotal support for the entire series of levers. The rod 19 is supported at. or near each end in brackets 2O and 2]. formed of l sheet material and 'secured to the casing 10 by Screws 22 extending through flanges 23 provided at the lower endsof the brackets.

While We haveshown the brackets as separately formed. it will be understood that ,the

21' may be formed from two brackets Z0 and a single piece 4of material if so desired. Each'bracket isprovided with an upwardly7 and rearwardly inclined open slot 24 within Which-the'rod 19 may bereceived. With this construction, the brackets 20 andv 2 1may be securedv withinthe casing and the levers 16 may lbe assembled upon, the rod 19, the rod 19 being thereafter inserted in the-slots 24 without' the necessity of providing openings in the sides of the casing. such as are shown in the Mitchell patent. This method of assemblingthe parts possessesimportant advantages, as it permits the disk-holders to be used in any casing of suitable size without in any way disfiguring of thecasing. l In order to yposition the levers Within the the outer surface casing, We provide a stop rod 25 supported in open Slots 26 in the brackets 20 Aand 21, and for holding the levers in open or forward position we provide a. second stop rod 27 which is mounted Wardly-extending lportion of. each lug or in slots 28 in the brack- Y vets 2O and 21, said rod 27 engaging a downprojection 17 when its respective lever is moved outwardly, as clearly shown in F ig. 4.

The'slots 2i, 26 and 28 are so disposed angularly that the side walls of the slots will prevent displacement of the rods by the pressure of the disk-holding levers when in either open or closed position, while at the same time they permit ready insertion of the rods after the brackets have been placed Within the casing.

In order to identify the different records, a numbered plate 30 is secured to the bottom of the casing 10 in such a position that the ends of the projections 17 are closely adjacent to the numbers upon the plate when the disk-holding levers are in their rearl position, the projections 1,7y then acting as indicators for distinguishing the dierent records.

' Having fully described the construction of our improved phonograph disk-holder, theoperation thereof will be evident from inspection of the-drawings. Any desired "record may be withdrawn from the casing by grasping the projecting handle 31 provided at the upper end of each lever 16 and thereby, `swinging the selected lever outwardly to the open position shown in dotted y lines in Fig. 2, in which position the disk 3.0

may be readily removed. `The lever will be lretained in open position by the engagement-of its projection 17 with the stop rod 27 while the remaining levers are held in uniform closed position by engagement with the stop rod 25.

. Having thus described our'invention, it will be evident that changes and modifications can be made therein by those skilled Y in the art without departing from the' spirit andscope thereof as setforth in the claims,

and we do not wish to be otherwise limited to the details herein disclosed, but

What we claim is:-

' 1. A phonograph disk-holder having, in v combination, a plurality of grooved diskholding levers, a rod upon which said levers are pivoted, a pair of stop rods eective to position said levers'- in either open or closed position, and supports for said. rods each having a plurality of open slots adapted to receive said rods and so disposed that said rods cannot be displaced therefrom by thev action of the levers in any position.

2. A phonograph disk-holder having, in combination', a plurality of disk-holding levers each having a projecting lug near its central portion, a rod upon which said lugs are pivoted, a second rodl engaging said lugs and acting as a stop for said le'vers when in open position, a casing within which said rods are supported, and a numbered vplate secured in said casingto designate said` levers, said lugs being positioned closely adjacent said plate' when the levers are in closed position and acting as indicators therefor.

3. A phonograph disk-holder having, in combination, a casing, a plurality of diskholding levers, and means for pivotally mounting said levers in said casing, said means comprising brackets secured in said casing, and a rod extending through an opening in each lever, said rod being received within open slots in said brackets, and said slots-being upwardly and rearwardly inclined, whereby said rod and levers may be readily inserted in and relnoved from said brackets as a unit after the brackets are mounted in said casing, and whereby they `are held against 'j accidental displacement LEANDER E.
