'fiAnemg-z BELLST SPEGIEIGATION forming part of .Letters Patent No. 229,569, dated July 6, 1880.

' Application filed April 12, 1830. (No model.)

Newport, in the countyeof Campbell and State of Kentucky,'have invented certain new and useful Improvements in Banging Bell's, (Case F and I do herebydeclare the followingto beafull, clear, concise, and exnctdescription of the .pjanying drawings, forming same, sufficient to enable others skilled in the art to which my inventionappertainsto make and use it, reference being had to the accompartof this specification, wherein;-

Figure 1 is an elevationyofa hell hung in accordance with my-inve ntion. 2 is a topsection of the stirrup-bolt, and Fig. 3 a side view of the suspending and the bell shown insection.

'Similarletters' of reference in the drawings indicate the same parts.

.My invention relates to the method of hanging light bells, more particularly alarm-bells,

from two hundred to seven hundred pounds weight, such as are usually employed for firealarms audit has for itsobject to simplify and reduce the cost of hanging the bells and. to preventthe jarring of the bell-supports when the bell is struck and during its vibrations.

In furtherance of this object the invention consists in the construction of a suspendingplate fastened to the top of the hell, combined with a stirrup-bolt secured to a beam, whereby the bell is suspended to swing freely when struck by the clapper, and without having its 'vibrations interrii-pted or resisted by the susv n vices.

In the drawings, A represents the bell, having an opening in the top to regeive-the boss of a crown-plate, B, to which the clapper O is pivoted.

D is the suspending-plate, placed over the opening in the top of the bell and bolted to the crown-plate, so asto clamp the bell between them.

The suspending-plate is cast with two standards, E E, uponits upper surface, through crown plates, with which two bolts, 1* F, are passed to secure it to the crown-plate.

The proximate faces of the standards are united by a round or circular bar, G, over the center-0t the plate, an d under this bar the loop of the stirrup-bolt IE is passed. The upper ends of the stirrup-bolt are then inserted in a timbcror beam, and held in place by nuts above the beam, shown in Fig. 1.

By this method of hanging the hell it is per mitted to swing when struck by the clapper, the cross-hart} turning freely in the stirrupbolt for the purpose. Therefore the swinging movements and the vibrations of the hell are not communicated to the beam tojar and strain inner-are the Vibrations of the bell interrupted.

Instead of pivoting the clapper to the under side of the crown-plate, thelatter may be'recessed or slotted to receive the end of the clapper and provided with bearings for the clap per-pivot in line with the edge of the opening in the top of the bell, as shown and described" in another application which I have made for Letters Patent of the United States.

The power for striking the bell is necessarily applied to the lower end of the clapper, preferably by means of ropes which pass over pulleys, as shown in the drawings, Fig. 1.

Having thus described my invention, what 1 claim is-- 1. The suspending-plate D, cast with the bolt-standards E E, united by the round or circular cross-bar G, in combination with the crown-plate B and the open-top bell, substantially 'a'sulescribed, for the purpose specified.

2. The combination of the suspending-plate- D E G, the stirrup-bolt H, and the crown-plate B-with the open-top bell, substantiallyas described, for the purpose specified.

In testimony of which invention I have hereunto set my hand this th day of March, A: D. 1880.
