SOUND COLLECTING AND irnANsriIT'riNe Original application filed May 29, 1924, Serial No. 716,626,"and in GreaitBrifti e r'ii 20, 1925. primed and this application filed April 21 1927. Serial lilo, 185,570. 4
This invention relates to sound-collecting and transmitting means, and in the embodiment shown as illustrative of the invention it is particularly adapted for use with dictation machines.
This application is a division of my copending application, S. N. 716,626, filed May 29, 1924.
The drawing is a side elevation, partly in section, of the embodiment of the invention herein claimed.
As in the usual form of device now used on dictating machines to collect and transmit sound from the dictator to the recording mechanism, the speaking-tube 10 is connected in any suitable manner to a handle 11a, having a hook-shape guard 12 which engages a part of the dictators hand, while the handle 11a is being held, and which assists the dictator in holding the handle. Opposite the guard 12 on the handle 11a, there is provided a button 13 which is used to control the operation of the machine from the handle 11a.
In sound-collectors, heretofore provided for use in dictating machines, the mouthpiece was connected to the handle portion by a tube which was bent so that, when the handle was held substantially vertical in front of the dictator, the mouthpiece would extend at an angle from the handle in the direction of the dictators mouth. When held in this position, the control button 13 was directly in front of the dictator, while the guard 12 was at the opposite side of the handle, a position which it was necessary to maintain due to the location of the mouthpiece with relation to the handle.
Hence, it is desirable that the mouthpiece be adjustable so that the position of the receiving or lip engaging portion thereof may be adjusted about the axis of the handle relatively to the hand-engaged parts on the ham dle 11.
The present invention provides a construction which permits setting the lip engaging portion 16a in relationship with the handle 11a to suit the convenience of the person clictating. For this purpose, the mouthpiece 15a is made with a beaded connecting portion or base 26, and the handle 11a is provided with a socket 29 comprisinga'plurality of'resilient i tongues'27 adapted to'en gage over the bead, thereby removably and rotatablyholding the mouthpiece.
The socket 29 comprises aneck 28 fixed-in the handle 1 1a and resilient tongues 27 are formed to extend'upwardly and inwardly to yieldingly hold'the mouthpiece under all normal"conditi'ons and yet permit'a rotating movement of the mouthpiece about the axis of the handle.
' The present invention also provides an improved mouthpiece construction per se. In this mouthpiece 15a, the lip-engaging portion 16a, the horn portion 14a and the connecting or base portion 26 are made as an integral unit, the former being at'an angle with relation to the latter forthe convenience stated above. The mouthpiece is preferably made by casting or molding processes, and hence can'be made to flare outwardly and to the side as much' as desired and permit's' the end or lip-engaging portion "to be 'oftheright size andiat the proper angle for dictating purposes.
may'be'varied to provide a mouthpiece of goodresonance: "For instance, the wallof "the lip engaging'portion may bemade substantially thickerthanthe wall of the horn portion as shown, and it is, of course, desirable thatthe lip-engaging portion be; so mades'o as to decrease-its tendency to vibrate when receiving sound and to withstand shocks due to accidental striking of the lipengaging portion against dictation machines or other objects.
Furthermore, when so made, the inner sound-conducting surface will provide a direct, unbroken and smooth conductor for free passage of the sound to be recorded.
This construction also permits easy removal of the'mouthpiece 15a from the handle 11a (by a strong outward pull) to facilitate the cleaning of same.
Variations and modifications may be made within the scope of this invention and portions of the improvements may be used without others.
Having now described the invention, what is claimed as new and for which it is desired to obtain Letters-Patent, is
1. A sound-receivingrdevice for dictation machine sound-conveying tubes comprising a handle, a mouthpiece having a base] poition, a lip-engaging portion, and a hornshaped portion formed integrally with the lip=engaging portion and being flared upwardly from the base portion and curving to position the lip-engaging portion at an angle to the axis of the base portion, the" walls of said mouthpiece being of progressively greater thickness" fromf'the base portion to the lip-engaging portion, and means engaging the base portion for removably and rotatably holding the mouthpiece to the handle portion. v
2. A sound-collector having a mouthpiece portion a horn portion integral therewith, and; having the lip of the mouthpiece portion disposed at an angle with relation to the base of the horn portion, thewalls of said mouthpiece being of greater thickness adjacent the lip engaging portion than adjacent the base of the horn portion.
A sound-receiving device for dictation machine sound-conveying tubes comprising a handle; a mouthpiece having a base portion, a lip-engaging portion, and a hornshaped portion formed integral with the'lipengaging portion and being flared outwardly from the base portion and curving to'position the lip-engaging portion at an angle to the axis of the base portion, said base portion being provided with a bead; and means comprising resilient tongues and engaging the bead on said base portion for removably and rotatably holding the mouthpiece to the handle portion, said means yieldingly holding the mouthpiece on the han'dle permitting removal thereof by hand without the use of tools, the walls of said mouthpiece being ofprogressively greater thickness from the base portion to the lip engagingportion.
Signed at Detroit, in the County of Wayne and State "of Michigan, this 18th day of April, 1927'. o
