PORTER I-I. ADAMS, OF BROOKLINE, AND FREDERICK MEYER, 0F CANTON, MASSACHU- SETTS.
ALARM-BELL.
To all whom it may concern:
Be it known that we, PORTER H. ADAMS and FREDERICK MEYER, citizens of the United States, and residents, respectively, of Brookline, in the county of Norfolk, and Springdale, Canton, in the county of Norfolk, both in the State of Massachusetts, have jointly invented a certain new and useful Improvement in Alarm-Bells, of which the following is a specification, reference being had to the accompanying drawings.
This invention relates to the class of alarms used, more or less commonly, by the drivers of automobiles, ambulances, fire department vehicles and the like, and our immediate object is to provide at reasonably small cost a plurality of bells of different tones, preferably harmonizing tones for automobiles, and clanging, discordant, tones for fire department vehicles and this desirable result we attain by the use of aplurality of bells which may be rung by a single movement of a suitable plunger which may be operated manually or by foot, as may be most convenient.
For the purpose of clearly demonstrating our invention we have provided the annexed drawings wherein Figure 1 is a perspective view of our improved device having the plunger removed. Fig. 2 is a sectional view taken on the line 22 of Fig. 1 and showing particularly our method of arranging the several clappers.
Fig. 3 is a detached view of the plunger which, in this case, includes a head designed for hand or foot pressure.
Referring now to the drawings, the numorals 1O, 11 and 12 represent bells of any suitable construction, preferably as dis closed. The several bells being fixedly secured to a central tube 13 which in turn is adapted to receive a plunger 14. Integrally located upon the said plunger are lugs 15, 16 and 17 so designed and located as to engage projections 18, 19 and 20 upon clapper arms 18*, 19 and 20 The said projections extend through openings in the tube 13 into the path of the lugs 15, 16 and 17, as the rod Specificationpf Letters Patent.
Patented Jan. 115, 191%. Serial No. 155,674.
14 is forced downward in said tube. The clapper arms are pivoted in collars 21, 22 and 23 which are soldered or otherwise secured to the tube, as will be best seen by reference to Fig. 2 of the drawings.
lVe have caused to be inserted within the tube 13 a spring 24 for the purpose of re turning the plunger to its normal position (indicated by dotted lines in Fig. 2) and, at the same time, produce a double action upon the bell clappers inasmuch as either an upward or downward motion of the plunger 1% brings the lugs 15, 16 and 17 into engagement with the clapper projections 18, 19 and 20 thereby causing the clappers to strike the bells.
Our described improvement may be screwed, or otherwise secured, to any available surface such as a baseplate 25, whereby a rest for the spring 24 can be secured; or shoulder suitable for supporting the said spring may be formed integral with the tube 13.
It is obvious that the construction as herein disclosed produces a double acting chiming bell alarm that is specially noticeable and etlicient and one that will return automatically to its initial position immediately upon releasing the plunger from pressure.
Having thus described our invention we claim as new and wish to secure by Letters Patent 1. A chiming bell comprising a plurality of bell members, clappers for said bell members, and an operating plunger common to all of said clappers.
2. A chiming bell comprising a plurality of bell members of different tones, clappers for said bell members, and an operating plunger common to all of said clappers.
3. A chiming bell comprising a plurality of bell members, clappers for said bell members, an operating plunger common to all of said clappers, and means for automatically returning the said plunger to its normal position.
