1 DOOR BELL AND KNOB.
Application filed April 8,
To aZZ w/wmizf may concern." Be it known that I, THOMAS M. KwAs- Nnasin, a citizen of the United States, residing at 62 New Litchfield St, Torrington, county oi? Litchfield, State of Connecticut, have invented an Improvement in Door Bells and Knobs, of which the following is a specification.
This invention provides a novel and compact arrangement of door latch operating mechanism and door "bell, wherein one of the door knobs of the latch operating mecha nism consists of a bell of the push button type and the other knob carries a push button by means of which the bell may be made to ring.
With the above and other objects in View, the invention consists of the combination and arrangement of parts as now to be fully described and hereinafter specifically claimed:
In the accompanying drawing forming a part of this specification,
Fig. 1 is a fragmentary elevation of a portion of a door, showing the outside knob and its push button; and i Fig. 2 is a sectional view on line 2-2 in Fig. 1, but showin a portion of the outer edge of the door anv the door lock and latch in elevation. r
10 denotes a door, 11 the lock thereof and 12 a latch of any ordinary or preferred construction which is carriedby the lock. 13 is a hub which is located in the door and lock and is constructed to carry a spindle 14: the ends of which extend beyond the hub at both sides of the door. The spindle may be of any ordinary construction suitable for its purpose. When now door knobs have been fixedly attached to the ends of the spindle, the door latch operating mechanism is complete. By turning either knob the spindle is turned in the hub to actuate the latch. The structure thus far described tudinal opening, denoted by 15, for a purpose to be explained. The outer door knob, denoted by 16, may be of wood or other suitable material, and'the inner knob. denoted by 17, may be of material suitable for a door bell. The knobs may be attached to theends of the spindle in any suitable manner. As

shown, they are provided on their under .sldes withprojecting portions which are hollowed out s as to fit the spindle. Set screws 18 hold the knobs to the spindle. Outer knob 16 is cut away as shown at 19 to provide for the insertion of apush button 20 in this knob, and between the hollowed out and cut away portions of knob 16 isa longitudinal. opening 21 which is adapted to aline with the opening through the spindle. Inner knob 17, as shown, is provided with a spring winding portion 22 'which serves as the bell proper, and beneath the spring winding portion with bell operating mechanism (not shown). A. bell control button 23 extends fromthe bell operating mechanism and is arranged so that it alines with the longitudinal hole in the spindle. It is to be understood that the particular kind of push button bell to be used with the present invention is immaterial, it only being necessary to provide a bell which comprises the inner knob of a door and which can be actuated from a push button in the outer knob. A relatively long pin 24 having a head 25 extends loosely through the opening in the spindle and through opening 21 in knob 16 so that its head rests against the bell control button and its end opposite the head rests against the bottom of the push button, as very clearly disclosed in Fig. 2. The head of the pin is of a size to preclude its passing into the spindle, as will be readily understood, and the bell control button is spring pressed so that it normally assumes the position in which it is shown in Fig. 2. The pin is of proper length to position the push button about as shown in Fig. 2. I
When the push button is forced a slight distance into knob 16. the headed end of the long pin will cause the bell control button to move to the left in Fig. 2, that is, to operate the bell. When the push button is released, the spring pressed bell control button will move back to its normal position and cause the pushbutton to return to the position it occupiesin Fig. 2.
single structure, door latch operating mechanism and a door bell, a combination heretofore unknown, as far as I am aware. The advantages of this novel combination will be at once apparent. Frequently, door bells are positioned in doors and in the neighbor'- It will be seen that I have provided in a i hoodor doors in obscure positions Where they are hard to find. The novel door bell of the present invention'is located in a most prominent and in very' convenient -position. 7
It is to be understood that while I have described a specific structure of door knob and bell, such changes may be made in the construction of parts as fall within the scope of the appended claims. The combination door-bell and inner knob as disclosed herein is a satisfactory and convenient arrangement. Itwill be seen that the-bell can be easily wound by simply turning spring winding portion 22 on its pivot. In other 'words, the inner lamb and door bell may be constructed after the fashion of a bicycle bell of an ordinary and well known form.
In addition, if found desirable, the bell winding portion may be-locked in position 7 so that it will not be accidentally turned when the latch is'being operated from the inside, and the lock may be actuated'to release the bell winding portion when the bell operating' mechanism needs winding. I The door bell and lnner knob can also ofcourse -be painted any desirable color and can'be made to otherwise appear as a duplicate of the outer knob.
What I desire t claim is:
1. In a door latch; the cembination of an outer knob, an inner knob, a hollow spindle therebetween, a push button centrally disextending between said push button and bell 7 control button and provided with an enlarged head adapted to abut the head on said bell control button, saidstem engaging the push button for actuation thereby, all of-said buttons and stem beingfreely rotatable relative toeach other. v V In testimony whereof I afiix my signature.
