Application filed December 3, 1909. Serial No, 531,183.

To all whom it may concern: i

Be it known that I, FRANK VSETECKA,

' citizen of the United States,. residing at /Vaucoma, in the county of Fayette and 5 State of Iowa, havevinvented certain new 'and useful Improvements in Automobile- Horns, of which the following is a specification. I r This invention relatesto pneumatic-signals and more particularly to a horn'especially adapted for use on automobiles and the like.

- The object of the invention is to provide a comparatively simple and thoroughly eflicient device of the character described, designed to take the place of the ordinary rubber bulb and so constructed that the same may be readily taken apart to effect any necessary repairs thereto.

A further object is;.-t0 provide a horn in which the vibratiniieed' is; actuated to sound an alarm by sliding the bulb or cap longitudinally on the air conductor.

A further object is to rovide an .au't0 mobile horn including a sliding cap or bulb having'a cylinder disposed within the same for the reception'of a stationary plunger, there being a coil spring interposed between the plunger and cap for returning the latter to normal positionafter said .capis depressed. I

A still further object of the invention is generally to improve this class of devices, so as to increase their utility, durability and efiiciency, as well as to reduce thec'ost of manufacture. I

Further objects and advantages will appear in the following description, it being understood that. various changes in form, proportions and minor details of construction may be resorted to within the scope of the appended claims. I

For a full understanding of the invenl l0I1 and the merits; thereof and also to acquire a knowledge; of the 'details ,of construction and the means for effecting the result, reference is to'be had to the'follow- .ing description and accompanying drawings, in which:

' Figure 1 is a side elevation of aportion of an automobile rovided with a horn constructed inaccor ance with my invention; Fig. 2 is a vertical sectional view of the alarm; Fig; 4 is a transverse sectional view -taken on the line 44 of Fig. 2 and looking in the direction of the arrow.

Corresponding and like parts are referred to in ,the following description andindicated in all the views of the drawings by the same referencecharacters.

The device comprises a tubular member or air conductor 5 having its upper end threaded at 6 and its lower end 'operativ'ely connected with a coupling 7 carrying a vibrating reed or other sound producing element,.indicated at 8. 4

Slidably mounted on the air conductor 5 is a bulbous cap-piece or'actuating member preferably formedof metal and constructed in two sections 9 and 10; The upper section 9 is substantially sphericalin contour and is provided atitslower end with interior threads 11 for engagement with the correspondingly-threaded end of the lower section- 10, there being an annular shoulder 12- formed on said lower section for engagement with the adjacent end of theupper' section 9, as shown. "The lower section 10 is preferably inclined or tapered in the di-- rection of the. air conductorf 5 and is provided'with a centrally disposed opening 13 85 thus to allow the cap'to slide freely on the to permit the passage of said conductor,

conductor when it'is' desired -to actuate the med 8 to sound an alarm. Disposed within the upper sectiont), is a cylinder 14, the

lower endof which extends within the s'ection 10 and is welded or otherwise rigidly secured thereto, the lower or fixed end of the cylinder 14 being provided with an in wardly extending stop flange 15 for engagement with the p unger 16. The plunger 16 comprises spaced disks or plates 17 having a strip of leather, rubber or other yieldable material interposed between the same and retained in position by means of clamping; nuts 18 bearing against the disks l7, and engaging the threaded end 6 of the conductor 5, as best shown in Fig. 2 of the drawings.

.A coil spring 19 interposed between the H plunger 16 and theupper end of the cap section 9 for the purpose of returning the cap to normal position after the same. has been depressed to actuate-the soundingelementS; In order to permit the escape of air from horn bulb showing the cap piece in noromal position;'Fig. 3 is a similar view of the bulb or cap piece depressed to sound an the chamber 20 when the cap is released, the walls of the opening 13' are formed with a plurality of spaced grooves or recesses 21 through which the air is forced when the conductor '24 with said coupling member 7,

cap is moved to extended position by the action of the coil spring 19.

The upper section 90f the cap is prefer- I ably covered with a strip of leather, rubber 'or other yieldable material 22 so as to permit the operator to readily grasp the cap when operating the device.

Thus it will be seen that when a downward pressure is exerted on the capfithe latter will slide longitudinally on thei'air bond'uctor 5'and the airin the upper section 9-will be forced through said air conductor '5 and against the reed 8 so as to'vibrat'e' the same and sound an-alarm, the 'spring'.19 serving to return the cap to extended or normal position after the hand has-been released from said cap.-

Thehorn proper, indicated at 23 may be connected directly with the coupling member 7 or through the medium of a flexible 1 as shown in Fig. 1 of the drawlngs.

' -It will herebe noted that the-,construction B-y removing the upper section 9 and detaching the coupling member 7, the lower section 10 of the bulb carrying the cylinder '14, may be removed from the air conductor 5 so as to expose the plunger 16 and its associated parts when it is desired to effect any repairs thereto.

" of the-device is such that the cap will work equally as-w'ell in cold weatheras in warm- I weather, which is a very important feature "in thisclass of signals. p I I Having thus described the invention, whatv is claimed as-new is:

" '1. .An automobile horn including an air 1 conductor, a sound producing element disried by said conductor,

posed'wi'thinhthe conductor, a plunger cara cap surrounding the 'plun gerya' cylinder secured to and entirely *housed' within the cap and bearingagainst .Isaid plunger; for guiding the'cap, said cap and cylinder being fthrough' Said'co'nductOr to the sound producing'element, and a spring dispose'dwith in' the cylinder and having one end thereof .within the conductor,

the air conductor, a e'aphavlng an inner wall .posd within the conductor,

tions being provided v movable longitudinally of the conductor for forcing a current of air 2. An automobil including an air conductor, a sound-producing element disposed fitting around the plunger and movable with said cap longitudinally of the conductor for directing a current of air through one end of the conductor to the soundproducing element, said cap having an opening therein'for the reception of the conduc tor, there being a-series of spaced grooves formed in the wall of the opening and communicating with the interior of the cap, and means interposed between the plunger and cap for returning said cap to normal position..

3. An automobile horn including an air conductor, a sound producing element disposed within the conductor, a plunger carried by said conductor, a cap movable longitudinally of the conductor and formed of d'etachably connected sections, .a cylinder carried by onev of the cap sections and forming aguide for the plunger, and means interposed between the plunger and the upper 'a plunger secured to section of the cap for returning said cap to I normal position.

4t: An automobile horn including an air conductor, a sound producing element disthreaded on the upper end of said conductor a cap movable longitudinally of the conduetbr and formed of mating sections having interengaging parts, one of said secwith an opening for the reception of the conductor and having a series of grooves formed in the walls thereof and'icommunicating with the interior of the cap,'a cylinder carried by one of the cap sections for guiding the plunger andhaving its lower end provided with an inwardly extending stop flange, and a spring interposed-"between the plunger and the upper section ofthe'cap; a
