Description
UNITED STATES PATENT OFFIC WALLACE r. MUNGER, on NEW BRITAIN, CONNECTICUT, ASSIGNOR To P.
a F. OORBIN, OF'SAME PLACE.
IMPROVEMENT IN DOOR-BEL LS.
' Specification forming part of Letters Patent No. 116,082, dated June 20, 1871.
To all whom it mag concern: Be it known that I, WALLACE T. MUNGER, of New Britain, in the county of Hartford and State of Connecticut, have invented and made an Improvement in Door-Bell Attachments;
and the, following is declared to be a correct purpose I make use of a revolving tumbler actuated by the spindle of the crank, and acting upon a loose spur-cam wheel that gives motion to the lever of the hammer when moved in either direction, and there is a certain amount of play or motion allowed between the tumbler and the spur-cam wheel, so that thecams may be freely moved out of the way of the end of the hammer-lever as said lever is moved to strike the bell.
In the drawing, Figure l is an elevation of the parts of the bell attachment with the bell and cap-plate removed. Fig. 2 shows the Capplate removed. Fig. 3 is a section of the parts at the line as w; and Fig. 4 is a section at the line 3 y. I
The base-plate a is made with a stud, b, carryin g the bell c. d is the hammer upon a spring-arm or lever upon the fulcrum e,- and t is the end of such lever, against which the spur-cams 0 on the wheel 1' operate. The wheel 1" revolves with the spindle h and a crank thereon; but instead of being directly connected thereto there is a revolving tumbler, s, intervening, the same beingconnected with the spindle h by a square hole for the spindle to pass through, and there is an arm, t,iupon said tumbler s that extends between two stops, 2 2, upon the spur-cam Wheel 1', and this ca-m- 'wheel 1" has a circular bearing upon the tumbler s, and the parts are held in position by hammer down upon the bell, the part i of the lever presses the said cam-Wheel around sufficiently to prevent the cam obstructing the movement as the bell is struck, the space between the stops 2 and arm 1. allowing of this movement. -This construction allows of the parts being made so that they willoperate when the crank is turned in'either direction. The dotted lines in Fig. 1 show the hammer drawn back, and as the hammer descends the cam-surfaces slide upon each other and the cam-wheel 1" is moved forward, and the stop 2 (against which the arm t had acted in raising the hammer) moves on away from that arm, so that there is nothing to prevent the hammer descending with rapidity to strike a sharp blow upon the bell. To obtain the required space for the tumbler s and wheel 7', theyre- Witnesses:
