SIG-NAL-SOUNDER.

Specification of Letters Patent.

Patented Oct. '13, 1914..

Application filed April 6, 1914. Serial No; 829,781. a

To all whom it may concern- Be it known that I, WILLIAM BAU'MGART- NER, a citizen of the United States, residing at Mendocino City, in the county of Mendocino and State of California, have invented certain new and useful Improvements in Signal-Sounders, of which the following is a specification.

My invention relates to that class of signal-sounders in which reeds are vibrated by a fiuid current underpressure.

My invention is applicableto any use requiring the sounding ofa signal, the volume of sound being controlled by the size of the device and its tone or pitch being in accordance with the reeds used. The pressure current may be steam,or air, or any gaseous fluid and the source of pressure maybe varied according to circumstances and the use to which the device is put. For the sake of illustration and description, I will,disclose the device in the shape of a horn, such as may be used for automobiles, though it is to be understood that it may assume var ous shapes and sizes and it may be provided with various sound-amplifiers. 1

The object of my invention 18 to provide a simple signal-sounder, adapted for wide limits of volume and pitch, and to this end my. invention consists in the novel signalsounding device which I shall now fully describe by reference to the accompanying drawings, in which- Figure 1 is a longitudinal section of my device, the sound-amplifienbeing in elevation. Fig. 2 is a perspective view of the pair of opposing spaced reeds. Fig. 3 is a cross section on the line mm of Fig. 1.

Fig. i is a cross section on the line y-y of Fig. 1.

1 is a union indicating a connection for the device to any suitable source of fluidpressure.

2 is a pipe-section forming the housing for the reeds. This housing is fitted at its rear end to the union 1, and said rear endocarries a cross bar 3. In the forward end of the housing is fitted or provided a barrier or block a with a slot 5. To the forward end of the housing 2 is fitted a sound-carrying pipe 6, the rear end of which is enlarged to form a chamber 7 which, from its function, may be termed a reverberating chamber.

To the forward end of the pipe 6 is fitted the sound-amplifier or trumpet 8. The

reeds are 9. These, in their best form, are

metallic.- There is a pair of these" reeds which may be formedof a'single piece bent double'or twoseparate pieces; ,The reeds lie opposite and spaced from one another. At their rear ends they are fitted into the cross bar 3 of the reed-housing 2. thence pass forwardly in said housing, wholly free thereof and of eachother, and freely through the slot 5 in the forward vblock 4 and their extremities are best caused oped by the reverberating chamber 7 of the pipe 6.

They

In operation, the fluid pressure admitted to the rear end of the reed-housing 2 and" passing out'through the contracted slot 5 of the block l will cause the reeds to vibrate,

and theirfree extremities actingvery much 3 like the lips of a human operator will, in con unction with the reverberating chamber, produce 7 a characteristic sound very se viceable as a signal. I

I cla1m:

1. In a signal-sounder, the combination. of

a pipe for receiving a pressure.fluid-current; a pair of opposmg, spaced reeds within. said pip'e,said reeds being fixed at one endand thence extending in the same direction as the How of the fluid current; and a slotted barrier in the pipe through the slot'in which the free extremities of the reeds pass and beyond which they project. I

2. In a signal-sounder, the combination of a pipe for receiving a pressure fluid-current; a pair of opposing, spaced reeds within said pipe, said reeds being fixed at one end and thence extending in'the same direction as the flow of the fluid current; and a slotted barrier in the pipe, through the slot in which the free extremities of the reeds pass and beyond which they project, said pipe having. an

enlarged chamber enveloping the free ex-' tremities of the reeds.

3. In a signal-sounder, the combination of ties within said chamber being divergent one through the slot in which the forward ends.

of the reeds pass and beyond which they projeot; a sound carrying pipe secured to. the forward end of the reed-housing and enve1- oping the projecting ends of the reeds beyond the slotted block; and a connection with a source of fluid-pressure at the rear end of the reed housing.

5. In a signal-sounder the combination of a pair of opposing, spaced reeds; a housing for said reeds having a support at its rear end in which the rear ends of the reeds are fixed, and a slotted block at its forward end through the slot in which the forward ends of the reeds pass and beyond which they project; a sound carrying pipe secured to the forward end of the reed-housing and formed with an enlarged chamber enveloping the projecting ends of the reeds beyond the slotted block; and a connection with a source of fluid-pressure at the rear end of the reed housing.

6. In a signal-sounder, the combination of a pair of opposing, spaced reeds having their forward ends divergent one from the other;

a housing for said reeds having a support at cured to the forward end of the reed-housing and enveloping the projecting divergent ends of the reeds beyond the slotted block; and a connection with a source of fluid-pressure at the rear end of the reed housing.

7. In asignal-sounder, the combination of a pair of opposing, spaced reeds having their forward ends divergent one from the other; a housing for said reeds having a support at its rear end in which the rear ends of the reeds are fixed, and a slotted block at its forward end through the slot in which the reeds pass and beyond which their forward divergent ends project; a sound-carrying pipe secured to the forward end of the reed-housing and formed with an enlarged chamber enveloping the projecting divergent ends of the reedsbeyondthe slotted block; and a connection with a source of fluid-pressure at the rear endof the reed housing.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
