' I TALK NG MACHINE.

Appfication filed June 12, 1-919. Serial no. 303,349.

To all whom it may concern: A

Beit known that I, BERT E. LANE, acitizen of the Dominion of Canada, residing at Camden, in the county of Camden and v1i State of New Jersey, have invented certain new and useful improvements in Talking Machines, of which the following is a'specification.

One object of my'invention is to provide improved sound conducting means for talking machines which can be made cheaply and durably. I

Another object is to soconstruct my invention that it will permit the free movement of the sound transmitting elements of a talking machine and to avoid undue friction between the several parts. a

A still further ob ect is to make the parts of my invention in a manner so that they can be easily assembled or taken apart.

Another object is to so construct my in vention that it will be of comparatively light weight but will be'of suchstrength'as to vwithstand hard usage without injury thereto. V

These objects, and other advantageous ends which will be described hereinafter, I

attain in thefollowing manner reference be-" inghad to the accompanying drawings in which- 7 Figure 1 is a fragmentary elevation of a portion of a talking machine showing in central vertical section myinvention as forming'a part thereof,

Figure 2 is a fragmentary section taken on the line 22 of Figure 1, r

Figure3 is asection taken on the line 3-3 of Figure 1,

Figure leis a perspective View of an 'am-' plifying box or housing which forms apart of my invention,

Figureb is a from which the box or housing of Figure is made, said-blank being'starnped or cut from a piece of sheet materiahan'd Figure 6" is a top'plan view of a rollerretaining ring which forms a part of my invention. F: i .Referring to the*drawings,;10 represents V a cabinet of a talking machine and maybe developed form or blank made any suitable form including a platp form 11 and a baseboard 12. The plat form 11 is. spaced above the base board as illustrated and provides acompartment 13. y A box or housing 14 is made of sheet mav terial bent from a blank form 1'5, as shown e p in Figure 5; The form 15 includes" two op-r positely yflared extensions 16 and 17 which project .from a central portion 18 and two transverse extensions 19 and 20 which are substantially rectangular. The form lfi is adapted to be bent on the dotted lines 21 and each of the oppositely flared extensions 16 and 17 have edge portions 22 which,- when bent upon the dotted lines 23, .pro-, vide flanges 2 1 for embracing the bent extensions 19 'and20, asclearly shown in F igs ure's 1, 2 and 4:. Each of the portions 22' has small flaps or ears 25 bent therefrom, said ears having holes 26 throughwvhich screws 27 can-be inserted to secure the housing it to the base board 12 within the com- 'partment 13; -The extension 16 has a large circular hole '28, and the section "17 has a smaller hole29. These holes 28 and Y29 are so arranged that when the formic is bent to provide the housing 1 1' that theira'xes will be coincident and vertical; A cup- 30 i is adapted to fit withinthe hole '29 and has a flange 31' adaptedto rest upon the inner surface of the extension-17 ,(see Figure 1).

Inorder that the cup 3Ov be of suflicient depth for the purpose intended, the base board 12 ispreferably provided with a cavity 32 into which the lower portionv of the cup 30 fits. t i Y The housing 14 constructed as above described "will flare forwardly Within its width and into this housing fits the rearportion of a sound-amplifying horn 33, said horn flare ing forwardly in the usual manner. The rear end portion 3 10f the amplifying horn stops'short ofthe rear end portion 35 of the housing 14, as clearly shown in Figure 1,

and a sound conducting 1 tube 36 extends v substantially. vertically through the compartment 13 into the housing 14:, said tube passing through the hole 28 and having an aperture 37- in its side adapted to permit the'sound to pass into the amplifying horn 33, as will hereinafter be more fully described. A block 38 forms a closure for the lower end of the tube 36, said block having an upwardly and rearwardly extending curved surface 39 which is substantially tangent to the inner bottom surface of the horn 33 and the inner rear surface of the tube 36 so as to cause the sound,passing downwardly through the tube 36 to be deflected forwardly through the amplifying horn 33. The block 38 has a pivot rod 40 secured therein, said pivot rod being substantially vertical and having a portion projecting; into the cup 30. A ballbearing 4 1 is interposed between the bottom of the cup and the bottom of the pivot rod and serves to take the thrust and support the weight of the tube 36 and at the same time permit said tube 36 to freely turn.

The tube 36 extends through a hole 42 in the platform 11 and has a. portion which extends above the upper surface of said plat-- form. A tone arm 43 has a: substantially vertical portion 44 which fits within and 4 is secured to the tube-36 by rivets 45 or other suitable means. The tone arm 43 supports a sound box 46 in the usual manner andserves toconduct the reproduced sound into the tube 36 and then outwardly through the amplifying horn 33.

A hearing plate 47 has a hole 48 therein 3 which is in register with the hole 42 and throughthis hole 48 the upper portion of the tube 36 extends. A cap or cover plate 49 is mounted on the bearing plate 47, and screws 50 secure the plates 47 and 49 to the platform 11, said cap plate 49 also having a hole 41 in registry with the holes 42 and 48 but of smaller diameter than the outer diameter of the tube 36 The portion of the plate 49 which includes the hole 51 is positioned directly'above the upper end of the tube 36 and thereby prevents the tube 36 from raising out of its proper position. The bearing plate 47 has a plurality of annularly arranged bearing sockets 52 into which fit the trunnions 53 of bearing rollers 54 The peripheral surfaces of the bearing rollers 54 are adapted to engagethe outer surface of the top portion of the tube 36 and retain the tube 36 in a vertical position and permit its free rotation. The upper end portions of the trunnions 53 fit within holes 55 in the roller retaining ring 56. The retaining ring 56 is secured to the plate 47 by screws 57 and permits the plate 49 to be removed in'case it is desired to raise the tube 36 for cleaning or repair purposes, it being noted that it is merely necessary to remove the screws 50 in order to permit the entire tone arm and tube 36 to be removed from the cabinet.

1 The housing 14 can be easily and quickly made by cutting or stamping the form and bending the game into shape. The form 15 can be made of sheet metal or other flexible sheet material and is much more serviceable than a casting and is less liable to fracture even if the same is dropped or during transportation. Further than this, the arrangement of the holes 28 and 29 is such that the parts will be in substantially practical alignment and can be quickly put together. The cabinet 10 can be so made that the cavity 32 can be spaced from the rear and side surfaces of the compartment 13 so as to serve as positioning means for the housing 14; it merely being necessary to insert the housing from the front of the compartment 13 until the cup 30 registers with the cavity 32. The hole 42 in the platform 11 can be made appreciably greater than the outside diameter of the tube 36 so as to compensate for any'slight difference in alignment between the several parts and in this manner it is unnecessary for a workman who is erecting or assembling the parts to. bother or take time in finding centers, as is usual the custom with constructions of this character made prior to my present invention.

lVhile T have described my invention as taking a particular form, it will be under stood that .the various parts of my invention may be changed without departing from the spirit thereof, and hence I do not limit myself to theprecise construction set forth, but consider that I am at liberty to make such changes and alterations as fairly come within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is I 1. A talking machine including a unitary amplifying horn housing having two holes in alignment with each other and positioned one above the other; a sound conducting tube entering said housing through the upper one of said holes; and means providing a pivotal thrust hearing for said tube and positioned within the other of said holes; substantially .as described.
