To all whom it may concern:

Be it known that Lla'rnicn J. ODoN- NELL, a citizen of the Unitedfitates, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Combined Door-Knobs and Push-Buttons; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to figures of reference marked thereon, which form a part of this. specification.

This invention relates to a combined doorknob and push-button that is designed to provide a knob that is mounted on a spinspindle is vtubular and dle, which spindle is adapted to act as a tube for the wires, the knob also having, on

its periphery, a series of push-buttons which,

are adapted to 'make electrical connection when pushed.-

The invention is further designed to provide the knob with buttons that are normally a slight distance below the surface of its periphery so that they are not actuated accidentally when the knob is grasped and turned.

The invention is illustrated in the accom panying drawing, in which-Figure 1 is an elevation half 'insection of the improved knob, and Fig. 2 is a face view broken away to show the interior construction. Fig. 3 is a diagrammatic view of a wiring system in which the knob is used.

. The knob can be made in any well known manner, but is preferably made of two members 10 and 11, the member 10 having a collar 12 thereon which is screwed or otherwise secured to a s indie 13, which orms conducting means for the wires to be hereinafter described; The member 10 is provided with a series of radially arranged perforations 14 which are enlarged at the bottom to 'form a recess 15, and in each perforation 'ber 10 and then through the tubular spindle 13, passing out through an opening 27 in the side of the tubular spindle. The two members 10 and 11 are prei erably held together by of thescrewvs Q8, and in'this way a structure that is free from unnecessary projecting elements is devised and one in which a multiplicity or series of push-buttons are available on the periphery of a. knob for a door or for other like purposes, it being understood that the periphery of the knob can be provided with suitable legends identifying the buttons, or the buttons themselves can be marked. In Fig. 3 is iilustrated, diagranunati the arrangement the diffs ent slow the wires 18 each running t bell 29, and each bell 2? is conne d w wire 30 which runs to a battery 31 or other suitable source of electrical energy, the return wire 25 connecting the battery with the contact ring. The outward movement of each button is limited, and preferably by making a flange 32 on each butt-on 16, the flange engaging the end or the reces The push-buttons arranged 1 periphery of the knob are close one-i gether to ermit a group them be ated by the fingers of one so different apartments are to h" ously called, as in the case of is desired to arouse them, be and simultaneousiy done.

Having thusdescribed my invention, what I claim is 1. A door-knob of the conventional type forming a grip, a tubular spindle on which the knob is mounted, ssh-buttons arranged to slide in the eripery of the knob and radially in relation to the spindle, the buttons being arranged slightly below the surface of the periphery of the knob, contacts adapted to be operated. by each button, and wires connected with the contacts, said wires comprising electric circuits, one of which is closed when a button is pushed, the dis position of the buttons below the surface of the knob preventing any accidental operation when the knobis grasped to be turned.

2. A knob, a tubular spindle on which the knob is mounted, a series of buttons radially arranged to slide in the knob, a contact ring in the knob, a wire passing through the spindle and the knob and connected with the contact ring, sets of electrical contacts in the knob each set being adapted to be brought together when its button in the series-of buttons is pressed, wires passing from one contact of each set to the contact ring, and wires passing through the tubular spindle and the knob and connected with the second contact of each set of contacts.

3. A door-knob, a tubular spindle on which the knob is mounted, the knob having a chamber therein, a contact ring in the chamber, a wire passing from the contact through the chamber and the tubular spindle,

a series of push-buttons slidably arranged in the periphery of the knob, the knob having a recess underneath each push-button, a contact strip bearing on each push-button to normally hold it in its inoperative position, a wire connecting each contact strip with the contact ring, and a second contact in each recess, each of the second contacts having a wire passing therefrom through the chamber and the knob and through the tubular spindle.

4. A door-knob of the conventional type, a tubular spindle on which the knob is mounted, the tubular spindle acting as a conductor for wires, contacts in the knob, the wires being connected to the contacts, the wires being adapted to conduct an electric current, and push-buttons each adapted to operate a set of contacts to close the circuit, the buttons being arranged around the periphery of the knob whereby a multiplicity of the buttons can be operated by the fingers of one hand.

In testimony, that I claim the foregoing, I have hereunto setmy hand this 20th day of January, 1910.

PATRICK J. ODONNELL.
