RICHARD VALSI'I, OF NEV YORK, N. Y.
SOUND-RECEIVER FOR SPEAKING-TUBES.
SPECIFICATION forming part of Letters Patent No. 415,929, dated November 26, 1889.
Application iiled June l.1 1889. Serial No. 312,889. (No model.)
To a/ZZ whom t may concern:
vBe it known that I, RICHARD WALSH, of lthe city, county, and Stateof New York, have invented a new and Improved Sound- Receiver for Speaking-Tubes'of which the following is a full, clear, and exact description. My invention has special reference to receivers for connection to speaking tubes or trumpets used to improve the hearing, and has for its object to provide a simple, inexpensive, and efficient device of t-his character.
The invention consists in certain novel features of construction and combinations of parts of the sound-receiver and in the mode of connecting it to the air-tube of the instrument, all as hereinafter described and claimed.
Reference is to be had to the accompanying drawings, forming apart of this specification, in which similar letters of reference indicate corresponding parts in all the gures.
Figure l is a side elevation, partly in perspective, of an ear-trumpet or hearing-tube Vfitted with my improved sound-receiver, parts being broken away and in section. Fig. 2 is an enlarged central sectional side elevation of the sound-receiver and adjacent portion of the connected tube, and Fig. 3 is a cross-sectional elevation taken on the line :wein Fig. 2. The drawings represent the present preferred form of the sound-receiver A, which has an inner face or lining B, of cork-wood, and an outer metallic casin g or guard C, which serves chiefly as a protection to the cork-wood lining, but also by its quality of resonance improves the effect of the lining as regards clearness of enunciation of sounds due to speaking into or toward the receiver. I prefer to make the receiver in the conical or round tapering form shown; but it may be square and tapering, or of pyramidal or other tapering form.
The sound-receiver is connected to one end of a tube D, which is provided with the usual ear-piece E, and has an inner metallic lining lF, consisting, preferably, of one piece of brass wire bent into a continuous coil, which eX- tends from the soundreceiver to Ithe earpiece.
The cork-wood inner face or lining Il of the sound-receiver is of itself a most excellent conductor of sound, as I have discovered and amply demonstrated by many practical tests; but I have also proved that by bringing the inner end of the cork lining into communication or direct contact with the extremity of the inner metallic lining or coil F of the tube D the receiver is more eflicient in giving clearness of enunciation at the ear-piece.
I show the cork-wood lining B made up of thin tapering sections or plates of cork, which are preferably made to adhere closely to the inner face of the thin outer resonant brass casing or guard C, which is shown with a bead e around it -to facilitate a rm or more convenient hold of it by the hand of the user of the instrument. The cork-wood lining may, however, be otherwise litted in the light strong casing or guard within the scope of my invention; in fact, I may make the sound-receiver entirely of cork-Wood, which would necessarily provide the receiver with a cork-wood inner face which would receive and conduct the sound-waves to the tube and ear-piece.
lVithin the sound-receiver I prefer to fix or attach a central longitudinal partition or plate G, which is preferably made of corkwood,and extends from a little beyond the outer end of the receiver to a point about at or a little inside of the center of the receiver. This partition catches the sound-waves and deflects or guides them into the throat of the receiver and thence to the tube and ear-piece Y should the receiver not be held immediately in front of the person speaking into or toward it. More than one of these partitions may be used; but I get very good results from the one partition set centrally, as shown in the drawings.
At and across the inner part of the soundreceiver is fitted a perforated or wire-gauze partition or plate H, which guards the inner end or throat of the receiver and also the metallic lining F of the tube D from too sudden impact of sound-waves 5 or, in other words, this transverse partition breaks or tones down the sound-waves to give a clear enunciation at the ear-piece of what otherwise would be harsh or discordant sounds.
In connecting the sound-receiver to the earpiece tube D the end of the tube is placed Within an inner ferrule l), which is iixed to the casing B, and at its outer end has a bead or ICO rib b.4 Two or three strips I, of velvet or other suitable liexible fabric or material, are then laid upon the ferrule and the tube D, and are secured to the ferrule by a Whipping of cord or Wire J, Which securely binds the fabrics I to the ferrule, and While the end of the tube l) is held snugly to the inner cork face or lining of the receiver a second Whipping` of cord or Wire K is bound around the tube and the outer ends of the fabric-strips I, which makes a strong, flexible, and efficient connection of the sound-receiver and tube.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
l. A sound-receiver for speaking-tubes, made With an inner face or lining of cork- Wood, substantially as herein set forth.
2. A sound -receiver for speakingtubes, made with an inner face or lining` of corkwood, and an outer casing,` or guard therefor, substantially as herein set forth.
3. A sound-receiver for speaking-tubes, made with an inner face or lining of cork- Wood, and an outer metallic casing,` or guard therefor, substantially as herein set forth.
et. A sound-receiver for speaking-tubes, iliade with an inner face or lining of cork- Wood, combined with a sound-tube provided With a metallic inner lining, with which the cork-Wood inner face or lining,` of the receiver gonlllnunicates, substantially as herein set 5. A soundreceiver for speaking-tubes,
made with an interior longitudinal partition, substantially as herein set forth.
G. A sound -receiver for speaking-tubes, made with an interior longitudinal cork-wood partition, substantially as herein set forth.
7. A sound-receiver for speaking-tubes, made With a cork-Wood inner face or lining and a longitudinal cork-Wood partition, substantially as herein set forth.
8. A sound-receiver for speaking-tubes, provided with a cork-Wood inner face or lining,` and a longitudinal cork-Wood partition, combined with a tube having a metallic inner lining, with which the corlmvood inner face or lining of the sound-receiver communicates, substantially as herein set forth.
9. A sound-receiver for speaking-tubes, provided With a cork-Wood inner face or lining and a transverse perforated or Wire-gauze partition, substantially as herein set forth.
lO. A sound-receiver for speaking-tubes, provided with a cork-Wood inner face or 1ining', a longitudinal cork-Wood partition, and a transverse perforated or Wire-gauze partition, substantially as herein set forth.
Il. The combination, with a sound-receiver and air-tube, of flexible strips laid on the receiver and tube, and cords whipped around the receiver, the flexible strips, and the tube, substantially as herein set forth.
