DOORBELL AND BURGLAR Application filed July 2, 1928. Serial No. 289,928.

the invention consists in the novel arrange ment, construction and association ofparts,

- as hereinafter set forthanddescribed, reference being bad to the accompanying drawings, where,

Figure 1 is a plan view of the alarm;

Figure 2 is a sectional view on line 22 of Figure 1;

Figure 3 is a side View of the alarm;

Figure 4 is a view showing the manner of installing the invention as a burglar alarm in a resident; and,

Figure 5 is a view showing the burglar alarm as installed in a bank.

The alarm sounding mechanism embodies a supporting panel 1 of Wood or other suitable material uponwhich is fixed a hell 2 and a spring motor 3 for operating the bell striker 4. The spring motor and striker mechanism maybe of any conventional typeand is adapt ed, for the purposes of the invention, to oscil-V late the striker continuously about its pivot 5 until the spring is fully run down or until movement of the striker is checked, as here-L inail'ter explained. A lever 6 is pivotally mounted at 7 on the panel and extends crosswise of the latter between the bell and the spring motor, holes 8 and 9 being provided in the opposite endsof the lever for the at- I tachment thereto of operating cords or cables. Rigidly fastened to one arm of lever 6, so as to extend angularly therefrom in a position to engage the striker 4;, is a stop or check member consisting of a Hat resilient spring 10 having its free end ,11 bent, as shown. When the device is installed, the

mechanism is concealed by acover casing 12 dence with its inner end contacting with the spring check member 1Q. The lever 6 is normally positionethas shown in Figure 1, so

that the bent end 11 of check member 10 bears Ida-inst the striker 4 and prevents it from oscillating under the influence of the spring \motorr When the push button isforced in 1 wardly,it flexesthe check member 10 out of engagemeiit. with the striker and thus permits the latter to operate against the bell; Upongrelease ofthe push button, the check member springs back} into the path of the striker and preventsv further movementof the same.

- lVhen using the device as a burglar alarm for a dwelling, the panel 1 is preferably mounted upon a window facing,and' an operating cord or cable 15 is connected to the lever may be anchored at one end 16 to the door casing 17 and extended acrossthe door and behind a pulley 18 on theopposite casing, from'whence it is passed across one or more windows 19, to which it is connected at 20. It is also connected,as shown at 21, to the lever 6 of the alarm. Hence, any opening movement ,1 6. As shown in Figure l, the operating cord I y k of the door or windows will exert a pull on the cord that will result in the lever 6 being so moved about its pivot as to drawthe check 10 back from the striker 4 a distance sufiicient to enable the latter to operatefully and ring the bell. The cord may be formed of detachasshown in Figure 5, and a single operating cord 22 connects with the leverG andleads down through thereof into the bookkeqoefis balcony 23, extending substantially the length of the balcony, then down and under the flooring 24 in front of the tellers cages and under the offices, being anchored, as shown at 25. Suitable pulleys 26 are arranged to support and guide the cord in its movements and pull ropes 27 are attached tothecordfor the convenience'of the bookkeeper in the balcony;

In the lobby and office, push buttons 28 are located at convenient places in the flooring, and when depressed by the foot will exert pull on the operating cord suilicient to move a the lever 6 and release the striker mechanism,

whereby the alarm will be sounded.

Variations may be resorted to within the Cit scope of the inventionand portions of the -improvement-smay be used Without others."

Having thus described the invention, What is claimed as new is:

1. An alarm sounding mechanism including a support, a bell fixed thereon, a bell sounding mechanism including a striker adapted tov be oscillated about its pivot, a lever pivotally mounted on the support and having holes in its opposite ends for the at-v tachment thereto ofoperating cords or cables,

a spring check member fastened to one arm "oi the lever in a position to engage and prevent operation of the striker when the said arm is moved in the direction of the latter, and ajslidable push button extending through the support and adapted when forced in- Ward-1y to move the check member out of engagement with the striker; V r

2. An alarm sounding mechanism includinga'supporting panel, a bell mounted thereon, a pivotally mounted bell striker, clock Work for oscillating the striker on its pivot, a

anchored at one end and having its free end check member consisting of a fiat spring i normally engaged with the striker to prevent operation thereof, and a push button slidably fitted in an opening in the panel with its inner end bearing against said check member,

said push button being adapted when forced inwardly to flex the said check member out of engagement with the striker.

3. A combined door bell and burglar alarm consisting of supporting panel, a bell mounted thereon, a striking mechanism including a bell hammer, a centrally, pivoted lever mounted on the panel and adapted to be con- JEFF DAVIS PHILYAW.
