Description
' H. BROWN. Nautical Alarm-Bell.
Patented Dec. 16, 1879.
UNITED STATES PATENT OEEIoE. v
HENRY BROWN, OF CHARLESTON, SOUTH CAROLINA, ASSIGNOR TO HTM- SELF AND ALFRED BROTHERHOOD, OF SAME PLACE.
IMPROVEMENT IN NAUTICAL ALARM-BELLS.
Specification forming part of Letters Patent No. 222,622, dated December 16, 1679; application filed May 21, 1879.
To all whom it may concern:
Be it known that'I, HENRY BROWN, of Charleston, in the county of Charleston and State of South Carolina, have invented certain new and useful Improvements in Nautical position that the motion of the Waves will cause it to roll from side to side and strike against the interior of the bell.
In the accompanying drawings, illustrating my invention, Figure 1 is a side elevation, partly in section, showing aportion of the top of a buoy with my improvements applied. Fig. 2 is a plan view of the radially-grooved disk or table upon which the striking-ball rolls.
A indicates a buoy, which is to be anchored so as to float within a limited space. E indicates the bell frame or support secured to the top of the buoy, and 0 indicates the bell secured rigidly within the frame by means of a nut, or in any convenient manner. D indicates a circular disk or table supported upon a block or standard on the top of the buoy,
and preferably of adiameter something less than the greatest diameter of the bell. This disk is placed slightly below the bottom of the bell, and is grooved radially upon its upper surface, and a heavy metallic ballisplaced loosely upon it, so as to roll in the radial grooves back and forth by the tilting orswaying of the buoy under the influence of the waves. The radial grooves prevent the ball from moving in a circular direction, and cause it to strike direct blows against the interior surface of the hell.
I provide springs E around the circumference of the disk, projecting so as to be struck by the ball when coming in contact with the bell and throw it back ontof-contact with the bell after it has imparted its stroke. These springs should be as numerous as the radial grooves. In the center of the disk there is a flat, circular, plain surface, so-that the ball may readily take any direction from the cen ter.
Having thus described my invention, what I claim as new is 1. The combination, with the bell, of a grooved disk carrying a ball for striking the bell, substantially as described.
2. The combination of the rigidly-suspended bell, the grooved disk, the 'ball, and the ballretracting springs, substantially as described.
111 testimony whereof I have hereunto subscribed my name.
HENRY BROWN.
Witnesses it FRED. BROTHERHOOD, JAMES W. GETTY.
