DOOR BELL.
Patented Mar. 9, 1886.
Ila-337,658.
UNITED STATES PATENT OFFICE,
ELLIS S. BLOOMFIELD, JR, OF JERSEY CITY, NEW JERSEY.
DOOR- BELL.
SPECIPECATION forming part of Letters Patent N 0. 337,658, dated March 9, 1886.
Application filed August 6, 1885.
To all whom it may concern.-
Be it known that I, ELLIs S. BLOOMFIELD, Jr.,' a citizen of the United States, and a resi-v dent of Jersey City, in the county of Hudson and State of New Jersey, have invented a new and useful Improvement in Gong-Bells, of which the following is a specification.
My invention relates to that class of gongbells in which the bell-pull for operating the bell is retained in place by the spring that opcrates the hammer; and it consists in attaching to the base-plate, forthe tripping-lever to rest against, an adjustable stop, instead of the rigid stop, as ordinarily constructed.
The object of my improvement is to give the tripping-lever more play than is usually allowed to it, thereby keeping up the tension upon the pull-wire after it has become stretched from use.
Figure 1 is a side view of the gong and plate; Fig. 2, a front view of the plate and mechanlsm.
Similar letters refer to similar parts in both figures.
In Fig. 2, B is the base-plate; O, the tripping-lever, working on the fulcrum P.
L is the hammer, and G the hammer-arm, which is made of wire bent into suitable form to make a hearing about the fulcrum k, and also a loop, K, in which one end of the spring F is secured, and an eye in which the pivott' on the. trip is retained.
H is the trip, with a pinion, 1;, secured in an eye formed on the hammer-arm for the purpose, moving freely therein, and by means of a spring coiled about the base of the pinion (an end of which is seen at n) and the shoulder r, resting against that part of the hammer-arm coiled about the fulcrum at k, is retained in position to be engaged by the nose h of the tripping-lever, to which is attached at f the other'end of the spring F.
Serial No. 173,706. (No model.)
E is a movable stop secured to the baseplate by the pin e, so that it can be turned back out of the way, as shown by the dotted lines.
R is a stop to prevent the tripping-leverfrom being pulled out too far.
The manner of operating is this: The hammer-arm is moved inward away from the gong by the action of the tripping-lever against the trip until it escapes, when the spring F throws it quickly back against the stop m, and the elasticity of the arm G allows the hammer to reach the gong and make the stroke, after which, bythe further action of the spring F, the tripping-lever O is returned against the stop E. The trip H is moved back out of the way by the tripping-lever in passing, but is returned to position by the spring at, readyfor another operation. The first position of the tripping-lever O and the movable stop E, as shown by the black lines, is sufficient for the proper w rking of the bell; but after the pullwire has been properly adjusted to it in this position the stop E may be thrown back out of the way, as indicated by the dotted lines, and the tension of the spring F on the tripping-lever will cause it to strain the pulling wire and always keep it taut, and the attachment on the outside of the door or on the other end of the wire will be held snugly in place. I claim The combination of the tripping-lever t and the hammer-arm G, having the trip H attached thereto, the spring F, and the movable stop E, substantially as shownand described.
In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 3d day of August, 1885.
