Similar projections but; in different. positions are formed in the groove 6 of this member 5. These may conveniently take the form of screws 8, which pass through suitable slots in the members 3. These screws are preferably surrounded by a sleeve 9 of resilientmaterial such as rubber. In the grooves 4 and 6 are spring buffers 10 also of some resilient. material such as rubher. The projections 7, on the member 3 bear against the one set of ends of the buflens 10 or thelike, while the screws 3 on the other member 5 act as buttresses for. the other ends of the butters 10. The two members, 3 and 5, are clamped together face to face by a ring 11, or the like, so that they cannot move toward or away from one another although they may have some small rotary movement relatively to one another against the resistance of the resilient buffers 10. In consequence of this device when the needle is in use a certain amount of yield is afforded the needle carrying member 5 and this yielding action is exerted in a circumferential direction about an axis passing parallel with the diaphragm 12, although a movement of the needle carrying member 5, in the direction in vhich the needle tends to move while deflecting the diaphragm 12, is also provided. The back plate 5 is held to this member h by screws or the like passing through the rubber washer the holes in the member 5, through which such screws pass being made slightly larger than actually required. By this means relative circumferential movement of the diaphragm currying element 5 to the member 3 is allowed while a metal to metal contact is also obtained thereby preventing relative movement of these two members in-any other direction.
In constructing a diaphragm according to this invention a disk of wood 12 is provided some distance within its periphery ridge, which revents warping of the diewith a circuar concentric flange, 13, or phragm by atmospheric changes and the like. The portion. of the disk 12, withirrthe ridge or flange 13, is preferably made somewhat thicker than the rest of the diaphragm. It is found that. a wooden diaphragm of this character may be used for a long period without, warping and the sounds reproduced by it are of an exceedingly mellow tone. Instead of employing wood however for the diaphragm, other non-metallic materials or compositions such as-Gallalith (which consists of carbon milk and potato or the like) may be used.
It will be seen that. many modifications may be made in the method of carrying this invention into effect without in any way departing from the spirit of the same.
hat. I claim as my invention and desire to secure by Letters Patent, is:--
In a sound reproducing or recording apparatus, the combination of a casing; said casing having inner and outer walls spaced apart to provide sounding boxes; a needle vcarrier; a diaphragm; a sound pipe connected at one end with the needle carrier; a boxing disposed centrally of the casing and connected with the other end of said sound pipe; said boxing comprising a plurality of substantially rectangular walls; and a plurality of trumpets of equal length connected with said boxing; said trumpets extending through the inner walls of said sounding boxes and having their outer edges meet.- ing flush with the inner surfaces of the outer walls of said sounding boxes, substantially as described.
In witness whereof I have hereunto set. my hand in the presence of two witnesses. HENRY GEORGE WEEDER. \Vitnesses:
