HIRAM BARTON, OF EAST HAMPTON, CONNECTICUT.

IMPROVED HOUSE-BELL.

Specification forming part of Letters Patent No. 58,576, dated October 9, 1866.

To all whom it may concern Be it known that I, HIRAM BARTON, of East Hampton, Middlesex county, State of Connecticut, have invented certain new and useful Improvements in House-Bells 5 and I do hereby declare that the following is a full and correct description thereof.

My invention relates to bells in which the hammeris thrown back and forth across within the bell for the purpose of striking alternately on opposite sides.

My invention consists in combining with the hammer a circular flanged vibrating disk or cap plate provided with a stop and a spiral spring, the whole constructed and arranged substantially as herein described and shown, the disk-plate performing the oftice of sustaining and carrying the hammer back and forth,"

and also of a cover to protect the spring.

Figure No. 1 of the drawings is a plan view, and Fig. No. 2 a longitudinal section,of the bell and striking-machine.

The bell to is mounted, as usual, upon a standard, b, perpendicular to the bed-plate c. The vibrating cap-plate d has a central hub, e, which is bored to fit a stud-pin, d, which projects from the bed-plate c. The vibrating cap turns freely on this pin, beingkept in place by the screw-nut d The hammer e is mounted on the vibrating disk, the end of the wire arm 6 0f the hammer being driven into a hole in the boss 0 on the upper side of the vibrating cap-plate at a short distance from the axis or I center of vibration. Within the cap-plate lies a spiral spring, f, of either round or flat springwire, one end, g, being connected to the bedplate, and the other end, h, to the cap-plate.

A flange or rim, i, is cast on the under side of the cap-plate for the purpose of inclosing the spring to protect it, and also to give a steady support to the hammer and take off some of the strain from the center-pin. A stop, k, fast to the bed-plate, projects upward into the curved slot m in the cap-plate, for the purpose of fixing the range of motion of the plate in both directions to the proper extent of motion to strike the bell without holding the hammer in contact therewith so as to stop vibration.

The bell-wire a may be connected with the vibrating plate, as shown in the drawings, or by an eye or other similar connection screwed into the cap-p1ate at any proper point on the face of the cap-plate, which thus affords facility for making connections with a wire coming from any direction.

I claim- The arrangement and combination of the vibrating cap-plate, spring, and stop with the bell and hammer, constructed and operating substantially as described.
