Specification of Letters Patent.
Patented Oct. 13, 1908.
Application filed September 28, 1907. Serial No. 394,943.
T 0 all whom it may concern:
Be it known that I, GEORGE LEw1s PAT- TERSON, a citizen of the United States, residing in the city, county, and State of New York, have invented certain new and useful Improvements in Electric Bells, of which the following is a full, clear, and exact description.
My invention relates to signals and more particularly to improvements in electrically operated bells and the like.
In electric bells it is customary to provide a protecting cover for the electro magnet and other operating parts.
The object of my invention is to provide a cover of such construction as to more perfectly protect the operating mechanism.
In the accompanying drawings, I have shown my improved cover as preferably constructed, but it is to be understood that changes may be made in details without departing from the scope of the invention.
In the drawings Figure 1 is a top plan View of a bell frame and operating mechanism of an electric bell with the cover removed. Fig. 2 is a front elevation of a part of the frame and cover, showing the hammer rod opening, said view being relatively enlarged. Fig. 3 is a side view of the same parts, the cover being partly shown in section.
1 represents the bell frame of usual form, having an extended base for the mounting of the operating mechanism. 2 is the protecting cover for said mechanism adapted to be secured on the base frame 1. 3 is an opening in the side of the cover to allow for the vibration of the hammer rod 4:, which extends therethrough. 5 is a flange around the bottom of the cover 2, having a recess 6 on the 10 inthe latter.
2 at this point. This opening 3 affords easy access for dampness, dirt or other foreign substance. To close the opening 3 without obstructing the operation of the hammer arm 4:, I provide a shield 9, fitting neatly around the hammer arm 4. 11 is a bracket lip or casting formed on or secured to the base 1 adjacent to the opening 3, and of such height and width as to substantially close said opening beneath the path of the hammer arm 4. 12 is a stud on the bracket 11, adapted to engagethe shield 9 through a slot The shield 9 and bracket 11 together entirely close the opening 3. So far as necessary, the shield 9 will both slide and swing on stud 12 and thus freely follow the vibrations of the hammer rod.
From the foregoing it will be seen that the packing strip 7 makes an effective joint between the cover and the base, so that with the assistance of the shield 9 the interior mechanism will be protected at all times against dust and dam ness. While the shield as shown is pivote to the base it is in efiect a part of the protecting cover when the parts are assembled.
It will be seen that the two parts 2 and 9 form, in effect, when assembled, a twoart cover or protector for the interior mec anism.
What I claim is 1. In an electric bell, the combination of a base, a cover secured thereto having a slot, a vibrating hammer rod passing through said slot, a bracket below the path of operation of the hammer rod inline with said slot, a shield located between the bracket and said cover, and a stud and slot connection between said bracket and shield. I
2. In an electricbell, the combination of a base, a cover secured thereto having a slot, a vibrating hammer rod passing through said slot, a bracket below the path of operation of the hammer rod in line with said slot, a shield arranged between the bracket and said cover, a slot in said bracket, and a stud on the shield standing in said slot.
