MECHANICAL BELL-OPERATING- DEVICE. 7
Specification of Letters Patent.
Patented Oct. 13, 1908.
Application filed. August 20, 1907. Serial No. 389,411.
To all whom it may concern:
Be it known that I, JOSEPH GRAVELLE, a citizen of the United States, residing in the city of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Mechanical Bell-Operating Devices, of which the following is a specification.
V This invention relates to a call bell or other signal bell to be operated by hand regulated mechanical means.
The object of the invention is a bell of the trembler type but having mechanical means for operating substituted for electromagnets and batteries.
The invention consists in the novel features of construction hereinafter described, pointed out in the claims and shown in the accompanying drawings, in which Figure 1 is a detail perspective view of the bell, a housing inclosing a portion of the mechanism being indicated in dotted lines. Fig. 2 is a detail side elevation of the operating mechanism removed from the housing, certain shafts being shown in section, and the position of the parts when the lever is drawn outwardly being shown in dotted lines.
In these drawings A represents a metal plate having at its lower edge an angled foot portion A by means of which it can be secured in position, and mounted upon the plate A is a bell B. The front face of the plate also carries an angled and up wardly extending bracket 0. A lever E has formed upon one side and intermediate its ends a toothed disk E forming a rack segment and the lever is pivotally connected to the plate A by a suitable pin passing through the center of said segmental disk E. A pull wire D is connected to one end of the lever E and a coil spring G secured at its lower end to the plate A has the upper end secured to the remaining end of the lever E. A shaft H journaled in the plate A and in the bracket C carries a pinion J which meshes with the ratchet teeth of the segment E and also carries a toothed wheel A bell striker K ispivotally mounted upon a pin K carried by the bracket 0 and the striker-rod is pivoted upon this pin and carries upon opposite sides of the said pin, teeth K which engage teeth of the wheel J.
It will be obvious that as the wire F is drawn outwardly the disk E willbe rotated, thus rotating the pinion J and wheel J, and the teeth of the wheel J being alternately in engagement with the teeth K will impart during the rotation of said parts a trembling motion to the striker-rod K, thus sounding thebell in the same manner as an electromagnet.
A housing D shown in dotted lines incloses the bracket C, the lever E and the adjacent parts.
Having thus described my invention what I claim as new and desire to secure by Letters Patent is- A device of the kind described consisting of a bell, a pivoted toothed striker-rod, a lever, a spring connected to one end of the lever, a pull device secured to the opposite end of the lever, a shaft, a toothed-wheel on said shaft in engagement with a tooth of the striker-rod, a pinion on said shaft, a ratchet segment engaging said pinion and carried by the lever midway its ends, the pivotal point of the lever being at the center of said segment.
JOSEPH GRAVELLE.
