APPLGATION FILED AUG. 8, 1911.

HARRISON HURLBERT BGYCE, 0l?l OYSTER BAY, NEW YORK.
DIAPI-IRAGM SI/GNAL-HGRN,
. Befit known that l, Harrelson H. Boren, a citizen ot the'fUnited States, residing` at Oyster Bay, Nassau county, State oi New -Yorln'have invented certain new and useful Improvements in- Diaphragm Signahllorns, of which the following is a full, clear, and
` exact description.l
^ My invention relates to signals or alarms for automobiles, boa-ts and the like, and particularly to that type of `a horn in which the noise producing element is a rapidly vibrated diaphragm.
The object of the present invention is to provide a simple and effective means for vibrating said diaphragm, as well as to provide in an alarm superior structural details.
In the accompanying' drawings Figure 1 Ais a plan view of' the horn complete. 2 is a rear end elevation. Fig. 3 is in the main a section on theline 3-3. Fig. 4 is an end elevation of certain parts on the plane of the line 4 4, looking in the direction of the arrow.
l represents a motor arranged within a suit-able casing 2, which'may be provided with -a suitable bracket 3 for securing the instrument to the vehicle. n
i is a diaphragm casing secured to one as shown.
5 represents the front cover, which may carry a hornslike extension 6. y
A' is a ydiaphragm. which is properly supn ported at the front end4 of 'the diaphragm casing l and which may be held thereto by the cover 5, said parts being clamped together in any. suitable way, as by screws 8.
The arm l1 is preferably made irw'fl y spring steel, and the hammer norma j'. stands slightly spaced away from the diaphragm aforesaid. The center .of the daA phragin may, if desired, be provided with a reinforcing Ablock or'anvil facing the ham-- Specification of Letters Patent.
end ofthe case 3 in any suitable manner,l vbut preferably arranged eccentric thereto,
mer lll, which block-or anvil, as well as the hammer 14, may be hardened to ,resistlwear.
l0 as .well as thel front .shaft bearing' of the motor l. The .end of the arm 11 projects vinto the path of movement of the blades l0, and may be suitably shaped to be engaged thereby, wherebythe free end of the arm 1l will be pressed back and quickly released so that the spring tension will throw the hammer 14: ahead against the diaphragm to vibrate the latter. The end of the arm ll may be suitablyshaped to best receive the pitched surface of the blades 10. it being preferable to form a slight twist in the end of said arm 11 vcorresponding' generally with the pitch or the blades 10. The blades 10, as well as the end of the arm l1, should preferably be hardened to resist wear.v
In operation itis obvious that, as the motor revolves, each blade 10 will contact with the 'free end of the arm l1, pressing the same back and quickly releasing it so that the hammer 14 will spring forward and strike the diaphragm 7 to vibrate the same. These.
blows rapidly repeated produce a strikingly eil'ective alarm note, which is prolonged so long as the rotor 9 continues to revolve. The rotor 9 may be driven by any suitable means. In this particular instance I have indicated an electric motor associated with the several parts in such a way as to avoid the necessity of exible shafts and other connectionsalthough obviously in a broad sense my invention is not restricted to the particular type of driving` means employed.
It might be mentioned that it. is preferred to locate suitable washers of relatively soft material around the edge of the diaphragm 7 and between the same and the walls of the casing` by which it is gripped,
While l have shown my invention in its preferred form, I appreciate that various moditications and arrangements can be .made without departure from the spirit or scope thereof.
'What l claim is l. In an alarm of the character described, a diaphragm, av holder therefor, a hammer arranged to vibrate said diaphragm, and means for actuating said hammer comprising a rotating element and, a pitched blade.
2. ln an alarm. et the character described,
a'tented July 2i, lgid. Application led ugust 8, 1911. Serial No. 642,963'. y
a diaphragm, a holder Itherefor, a hammer ladjacent to said diaphragm but normally a diaphragm,
free therefrom, and means for vibrating said "I hammer comprising a rotating element and a pitched blade carried thereby arranged to engage the hammer.
3. In an alarm of the character described, a diaphragm, a hammer-adjacent thereto, a spring arm carrying said hammer, and means for vibrating vsaid hammer comprising a rotating element and a pitched blade carried thereby arranged to engage said arm.
4. ln an alarm of the character described, a` hammer adjacent thereto, a spring arm carrying said hammer, and means for Vibrating said hammer comprising'a rotating element and a pitched blade carried thereby arranged to engage said arm close to the hammer.
