BELL DOOR-KNOB.

SPECIFICATION forming part of Letters Patent No. 590,192, dated September 14:, 1897'.

Application filed y ,1897. Serial No. 685,133. (No model.)

To aZZ whom it may concern:

Be it known that we, EDWARD H. KINNA- MAN and BENJAMIN F. FLOUERS, citizens of the United States of America, residing at Fort Collins, in the county of Larimer and State of Colorado, have invented certain new and useful Improvements in Bell Door-Knobs, of which the following is a'specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in door-bells, and more particularly to bell door-knobs.

The object of this invention is to provide a combination door-knob and bell which is exceedingly cheap and simple in its construction and one which can be easily secured to any of the doors and locks now in use.

With these objects in View our invention consists in the particular construction of the various parts and in the novel manner of combination or arrangement of said parts, all of which will be described hereinafter and pointed out in the claim.

In the drawings forming a part of this specification, Figure 1 is a side elevation of the knob, spindle, and bell and knob combined embodying our improved features. Fig. 2 is a central vertical section through the same. Fig. 3 is a detail View of the clapper, mounted in the lower portion of the bell.

Referring to the drawings, A represents a square hollow spindle having a slot B in one end thereof, and mounted in the said slot a.

ratchet 0, provided with a band a, which is clamped around the spindle and secured to the sides of the ratchet. This ratchet is onehalf the length of the said slot and is adj ustably held therein by the said band. If preferred, the ratchet and band may be made in one piece and adjustably secured therein in any manner desired. A spiral spring b, having one end secured in the recess 0 of the hollow spindle A and he other in the recess 01 of the ratchet O,serves to keep the said ratchet located in the lower end of the slot, and when the said spring is contracted by forcing the ratchet to the upper end of the slot it is partly secreted within the recess 0 and partly within the recess cl.

The end of the spindle nearest the slot is internally screw-threaded and provided with a shoulder e for the support of the gong or ringing portion of the bell D,which is secured thereon by the screw f,which passes through the said bell and engages the internal screwthreads. Mounted upon the spindle below the slot is the lower portion ofthe bell E, having secured to its bottom a platform g, said platform having an aperture h, through which the spindle is passed. This platform is also at right angles to the said platform. sired, this platform might be dispensed with and the ears cast on the lower portion of the bell. Pivotally secured between these cars is a cam 'i, which is held in engagement with the ratchet O by the spring j, and secured to the upper portion or end and to one side of the said cam is an S-shaped wire Zc,having secured to its loose end a clapper L. Secured to the other end of the spindle is a knob F, provided provided with oppositely-disposed ears bent 7 If dewith an aperture rn, in which is secured the press-button G, provided with a shoulder at on the inside of the knob,whicl1 prevents the said button from falling out. Connected to this press-button is a rod H,extending through the hollow spindle and having a washer 0 secured thereto, in order to give the said rod a central location in the said spindle. The end of this rod is supported in the recess 19 'of the ratchet C.

By pressing the button the ratchet is made to traverse the slot in the shaft, thus throwing the cam into and out of engagement with the said ratchet and operating the clapper, which rings the bell repeatedly. It will thus be seen that we provide a bell door-knob which is compact, durable, and simple in its construction and will proficiently perform all of its intended functions.

Having thus described our invention,what we claim as new, and desire to secure by Letters Patent, is v In a bell door-knob the combination. of a square hollow spindle having a slot in one end thereof and a ratchet mounted in and adapted to traversev the said slot, a spring engaging said ratchet, a platform secured in the lower portion of the bell, said platform havin g an aperture through which the said spindle passes and oppositely-disposed ears bent at right angles to-the said platform, a cam pivotedly secured between the said ears, said cam supporting the clapper and held in engagement with the ratchet by a spring, a rod connecting the said ratchet with a push-bu tton, substantially as shown and for the purpose set forth.

In testimony whereof we have affixed our signatures in presence of two witnesses.
