Patented Apr. 12, 1932 UNITED stares PATENT* OFFICE FRANK C. HINCKLEY, F STRATFORD, CONNECTICUT, ASSIGNOR TO COLUMBIA PHONO- i GRAPH COMPANY, TNC., OF BRIDGEPORT, CONNECTICUT, A CORPORATION OF NEW` YORK PHONOGRAPH Application led September 26, 1930. Serial No. @4,4824

y V This invention relates to new and useful improvements in phonographs or talking machines and has particular relation to socalled portable phonographs, being an improvement on the structure shown in my United States Patentf1,776,905 of September 30th, 1930. i

An object of the invention is to p-rovide a phonograph which while small and compact and therefore particularly adapted for use as a portable or Stowaway phonograph yet is so constructed as to give large volume, its volume and tonal quality corresponding favorably with the volume and tonal quality of floor type phonographs. l

Another object is to provide a phonograph including animproved sound amplifying arrangement, the invention particularly relating to the bell or lmouthY portion of the amplifying system of anacoustic phonograph.

A further object is to provide a portable phonograph including a cover with which side wings co-operate when the cover is openwhereby to provide an extension for the horn or amplifier of the phonograph, a portionof said side wings being foldablewhereby when the machine isV closed as for transportation a compact and relatively small structure is had.

An additional Objectis to'provide a phono-y graph having characteristics statedr and wherein a record carrier ory other means within the lid or coveris so constructed that it divides the "bell or mouth portion of the amplifier which bell or mouth portion is formed by the cover ,and side wings inassociation with the body of the machine. kOther-objects and advantages will becom apparent from a consideration ofthe vfollowing description taken in connection withy the accompanying drawings whereinasatisfactory embodiment of the invention is shown. However, it isv to be understood that the invention is'not limited to the details disclosed since changes in the construction, combination and arrangement of parts will readily suggest themselves to' thosek skilled in the art. Since the invention comprehends all such variations and modifications as fall d within the scope of the appended claims, reference must be made to the annexed claims Figure l is a central longitudinal sectional view through the entire machine, the lid or cover being open, and the record carrying panel and khorn dividingmeans beinginy its lowered position; c v

Fig. 2 is a plan view of the cabinet or body of the machine, the cover or lid being removed andthe foldable portions` of the side wings being in folded position; n

Fig. 3 is a view looking from the right in lig. 2, the cover being in place and closed, a side wall ofthe body and cover being removed,` and the record supporting panel being shown in section; Y

Fig. 4 is a perspective view ofthe bell Vor mrith portion arrangement of the amplier; an A Fig. 5 is an enlarged sectional detail view showing the mounting for the lid orcover and the record carrying panel or horn dividing means. l

Referring in `detail tothe drawings,at 6 is shown the cabinet or body of the machine to one edge of which, preferably the rear edge, there is hingedly secured a lid or` cover 7 Within the cabinet or body 6 thereis dis# posed 'a partitionvor'motor board 8 secured inv any suitable manner as for example by having its edges set into the ,Walls ofa cabinet orbody asshownat9.vk f

The motor-boardor partition 8 is disposed relatively nearto the upper edge of the body 6 and a compartment 10V is formed beneath the motor board or between the motor board and the bottom 1l of the cabinet or body. At its rear edge the partition 8 is cut away as at 12 to form an exit for an amplifier 13 disposed within the compartment 10. The amplilier 13 willlater be more fully described..V

At itsunder side the partition 8 supportsy any suitable motor. indicated at 14 which through avertical spindle 15 extending upwardlyl through the partition, drives a turntable 16. Obviously, the turntable is for the 14 may be employed and that any type of turntable 16 may be employed, the particular type of motor or turntable having no relation to the present invention.

Through the forward end portion of the partition 8, or through that end or edge portion opposite the end or edge portion which is cut away as 12, the partition is provided with a sound entrance opening 18. A tone arm 19 carrying a reproducer 20 for cooperation with a record on the turntable 16, is secured to the partition 8 in a position to align its discharge end with the entrance opening 18 through thepartition 8.

It is to be noted that the entrance opening 18 is located in one corner portion of the partition 8. Secured to the underside of the partition in a position to receive sound through the opening 18 is the entrance portion of the horn or amplifier 13 which entrance portion may take the form of a casting 21 curving laterally of the cabinet as it curves downwardly and secured as by a flange 22 to the rear or small end of a horn or megaphone 23 which is preferably of metal, as for example tin.

This horn 23 as shown is substantially Vrectangular in cross section and comprises top, bottom and side walls and the casting may be secured to the horn as by bolts 24. As herein disclosed the amplifier 13 is substantially the same as that disclosed in my patent above referred to and extends across the cabinet and then rearwardly therein, increasing in cross sectional 'area as it progresses from front to rear, and at its rear or discharge end being substantially the width of the cabinet. The side walls 25 and 26 of the horn portion 23 abut against the rear wall of the cabinet as does its bottom wall 27. These three walls are held in position and against rattle by meansof a block 28 having a curved surface 29 for the purposeof directing the sound upwardly through the cutout portion 12 of the partition. Top vwall 30 of the horn extends to a point substantially flush with the edge `of the cutout portion 12 and the rear edge portion of said wall 30 is rigidly secured to the partition as by means of a strap 31.

Lid 7 is connected to the cabinet 6 as by means of a hinge 32 and the lid has secured to it a pair of side members or wings 33 preferably of metal. These members or wings 33 are adapted to move into slots 34 in the cabinet when the lid is moved to closed position and when the lid is in open position these members 33 close the corners at the connection between the cover or lid and the cabinet or body. In this manner an extension of the amplifier 13 is provided since the lid, side wings and partition 8 cooperate to provide a bell or mouth portion for the amplifier.

Mounted within the lid and movable about the same axis as that about which the'lid moves, is a record carrier or panel 35. This panel 35 is hingedly mounted through the medium of a bracket 36 bolted or otherwise secured to certain of the leaves of the hinge 32 as at 37. curved on its rear side as at 39 and co-operating with the upper edge or lip portion 40 of a metallic strip 41. This is probably best shown in Fig. 5 and the strips 38 and 41 cooperate to provide an unbroken surface at the hinged connection between the lid and record carrying member and the body.

The panel 35 is movable to a position within the cover 7 where it may be temporarily held by means of a catch 42 co-operating with a catch plate 43. Links 44 pivoted within the lid as at 45 and slotted as at 46 to receive pins 47 on the edges of the panel operate to limit the swinging movement of the panel outwardly of the lid. A cover 48 is hinged to the panelV as at 49 whereby record compartment 50 is provided, records 51 being shown in the compartment in Fig. 5.

The'V record compartment 50 begins at a point spaced from the rear or lower edge of the panel 35 and between its lower edge and the inner end oi the record compartment, the panel 35 has an opening 52 through it, the opening being preferably lined with metal as at 52a. This opening provides a passage whereby sound passing upwardly through the cut-out 12 in the partition 8 is divided, a portion of the sound passing up forwardly of the panel 35 and the remainder of the sound passing through the opening 52 and up between the cover 48 of the record compartment and the inner side of the cover 7.

Hinged as at 53 to the side walls of the cabinet 6, are ak pair of foldable wings or members 54 and 55. These members, when open or in extended positions, are so disposed with relation to the side wings 33 as to overlap the forward edges of rsuch wings 1 and further the members 54 and 55 extend upwardly and at their upper or free edges bear against the inner surface of the side rails or edges of the lid 7 as shown at 56.V

`Members or wings 54 and 55 may be temporarily secured in their extended positions by means of suitable catch members 57 However, this catch means or members 57 need only be used vfor holding the wings 54 and 55 in their extended positions when the record carrying panel 35 is within the lid and secured by the catch 42. At other times, that is when the panel 35 is in open position it is disposed between the foldable side wings 54 and as shown in Figs. 1 and 4 and will hold them in theirextended positions.

It is, of course, only when the panel 35 is in its open or extended position as shown in Figs. 1 and 4 that a divided bell or mouth portion is provided for the amplifier. lVith Panel 35 carries a. strip 38 Q tinuation,

.the panel in its closed position, that is, with the panel within the lid and secured by the catch 42 but one large bellor mouth is provided for the amplifier, that bell or mouth `being forwardly of the panel: 35. However, this bell or mouth portion will be considerably `larger than that heretofore provided. Also,.when the panel is in open position the double or divided bell or mouth portion Lis obtained. f

. Whenthe machine Vis to be folded as for transportation, it is but necessary to release the members or wings 54 or 55 from the catches 57 ,to move the panel to a position within the lid and tothen fold the wings 54 and 55:.one upon the other as shown inFig. 2. Thelid or cover 7 vmay then be lowered to the positionshown iny Fig. 3,-the-lid having -been secured in open position by means of a catch member 58 cto-operating with one of they wings 33. V

v Catches 59 may be used for securing the lid o r cover in closed position and may be provided with a carrying handle 60. Further, the exterior of the cabinet and the lid is preferably coveredy as with leather or imitation leatheras shown at 61. The wings or members 54 and 55 are preferably of metal, as for example brass, and to. prevent these parts from unnecessarily vibrating and also to have them so color ofthe covering material 6l, .these wings are ,preferablyI covered on their, inner and.

outer` surfaces with such material designated 62 which may be glued or cemented or otherwise secured to them. s
