FIRE ALARM BELL ACTUATOR.
APPLICATION man JUNE 21.19l9.

NORRIS PETER5. lNc.. LITHO, WASHINGTON. By C WELLQINGTON S. CLAY, OF HUTCHINS O N', MINNESOTA.
FIRE-ALARM-BELL ACTUATOR,
Application filed June 21, 1919. Serial No. 305,851.
; To all whom it may concern Be it known that I, WELLINGTON S. CLAY, citizen of the United States, residing at Hutchinson, in the county of McLeod and State of Minnesota, have invented certain new and useful Improvements in Fire- Alarm-Bell Actuators; and I do hereby declare the following to be a full, clear, and exact'description of the invention, such as will enableothers skilled in the art to which it appertains to make and use the same.
This invention has for its object the pro.- vision of a simple and highly efficient mechanism for operating or sounding large bells or gongs for various purposes, such for instance, as for sounding a fire alarm in small towns or communities. stated, the invention consists of the novel devices and combinations of devices hereinafter described and defined in the claims.
In accordance with this invention, a hammer carried by a suitable lever is operated through suitable gear mechanism, from an electric motor. This electric motor may be operated through a circuit controlled from a telephone station or from any other suitable station; but this feature of operating the motor has not to do with the present invention.
In the accompanying drawings which illustrate the invention, like characters indicate like parts throughout the several views.
Referring to the drawings:
Figure 1 is a side elevation of the improved gongs or socalled actuated mechanism, some parts being broken away;
Fig. 2 is a fragmentary view in side elevation of similar parts shown in Fig. 1
viewing the same from opposite side; and
Fig. 3 is a plan view showing the hammer and its operating lever and associating parts.
A portion of the gong or bell as shown in Fig. 1 is indicated by a numeral 4. The mechanism of the bell or gong actuating device is mounted on a suitable bed plate 5. The hammer carrying lever is made up of a main member 6 and laterally spaced flat bars 7. These members are rigidly secured together by rivet, or the like, at 8. A roller or small wheel 9 is located between and journaled to the ends of the lever Generally l bars 7. The lever made up of theparts 6 3' and 7, is intermediately pivoted at 10 toa pedestal 11,'rigidly secured on the bed plate 5.
The hammer equipped lever 6-7 is downwardly pulled by a-spring 12 attached to" the bed plate 5 by an anchoring hook 13,
and its upper ends to ,a' hook-equipped bracket 14 that is longitudinally adjustable onthe lever section 6, and isyadapted to be 1 rigidly secured thereto, by a set screw 15.
The bellor gong striking movement of the hammer 1s cushioned by a coil buffer spring '18. This spring 18 surrounds the upper end of a rod 19, which, at its lower end, is
25 on base5. Shaft 24 carries a large gear 26 that meshes with a small gear or pinlon 27 of a counter shaft 28. This shaft 28 carries a large spur gear 29 and is journaled in a pedestal 30 on base 5. Gear 29 meshes with a pinion 31 that is carried by the armature shaft 32 of a small electric motor 33 mounted on base 5.
Operation.
Motor circuits are of course, adapted to be closed at a distant point so as to throw the motor into action at will. When motor is thrown into action the tappets 23 will be moved at a relatively slow speed and in succession will come into .action on the roller 9 of the hammer lever 6-7. Each time a tappet 2?) acts on rollers 9 it raises the hammer equipped end of lever, against projection of spring 12, and when the tappet runs out of engagement with said roller, the I hammer lever will be suddenly relieved, and under the action of spring 12, the hammer 16 will be thrown against the bell or gong 4. The bell striking movement of the hammer, however, is cushioned by frame 18. In fact, it is highly; important that spring 18 should be so set that, normally, it will estals and provided at its long end Witha bell striking hammer, and provided at its short ends with roller, a main spring connecting the long end portion ofsaid lever to said base support, a fixed post rising from said base and extendingby the-short end of said lever, a coiled springonsaidpost reacting against the short end of said lever and against an adjustable abutment on the upper end of said post, and amotor actuated tappet operative on the roller of said lever to intermediately retract said lever and to release the same. 7
2. The combination With a bell, of a-base support, having. pedestals thereon, a'strik from said base between" the laterally spaced 7 member of said lever, an adjustable nut on the end of said post, and spring on said post reacting against said nut and against short end of said lever, said latter spring'operating to overcome the main spring to such an extent as to hold said hammer so that it will be normally disengaged from said bell and a motor actuated tappet opera'tive'on the roller of said'leven'to intermediately retract said lever and to release-the'same.
In testimony whereof I aflix my signature in presence of two Witnesses; V
