ANTHONY ISKE, OF LANCASTER, PENNSYLVANIA, ASSIGNOR TO ISRAEL Ii. LANDIS, OF SAME PLAGE.
DOOR-BELL..
SPECIFICATION forming part of Letters Patent No. 378,317, dated February 2l, 1888.
Application filed April 22, 1887. Serial Xo. 235,758.
To @ZZ whom, t may con/cern:
Beit known that I, ANTHONY Isnn, a citizen of the United States, residing at Lancaster, in the county oi Lancaster and State of Pennsylvania, have invented certain new and useful Improvements in Door-Bells; 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.
The object of this invention is to provide a bell which will be rung, without any sudden jaror shoclnbytheopening ofa door,andwhich Will'continue ringing a predetermined length of time, depending on the adjustment of the parts, which is variable at will.
IIitherto bells used for shopdoors or similar purposes have generally been arranged to be struck by some projection, which gives the bell a violent jar and may injure it. In no case, so far as I am aware, has the duration ot' the ringing been within control. I avoid these objections by means of the devices hereinafter particularly set forth and claimed.
In the accompanying drawings, Figure l represents a front elevation of my door-bell and operating mechanism, with part of the door and door-frame to which they are attached, the door being closed. Fig. 2 represents a plan View, the door being open and the alarm in operation. Fig. 3 represents a detail plan view of the lever. Fig. et represents a detail View of the inainspring, Winding-pulley, and some ofthe proximate parts.
A designates a. door, B a door-frame, and C a broad ilat bar attached at one end to the latter near one of its upper corners, the said bar extending upward, as shown, or, if preferred, horizontally over the doorway. This latter cnd of the bar carries a casing, D, which incloscs a pulley, E, and has a train of clockwork, It, and a bell, G, attached to it. The shaft II of pulley E has the inner end of the mainspring I of said train attached to it, said spring` being Wound around said shaft and attached at its outer end to one of the pillars .I
ofthe plates K of said train of clockwork. Said shaft I-I also carries a gear-Wheel,L,which meshes with a pinion or lantern Wheel, M, on
'said door-frame.
(No model.)
rocking escapeinent-shaft P engage this escapement-Wheel. This latter shaft carries also a hammer, Q, which operates against the bell G so long as the clock-Work F (comprising said mainspring, gear-Wheels, and escapement) is in action. A cord, R, is attached to the pulley E and passed around it, so that a' pull on said oord Will turn said pulley and Wind the spring I. I therefore call this the winding-pulley. The said cord passes out through an opening, d, in casing D, then down to and around a pulley, S, which is free to turn on a stud, s, attached to bar C near its lower end. said cord It passes again, in a second line at right angles to the first, to the opposite upper corner of the door-frame, Where there is another pulley, T, on another stud, t, attached to The said cord, after passing around said pulley T and through a guide-eye, U, is finally attached to the short arin o of a bell-crank lever, V, which is pivoted at its angle to a bracket, V', attached to the upper part of said door-frame. Said lever has horizontal vibration when set free, but is held stationary by contact of its long arm c with a rigid upwardly-extending nager, IV, attached to the door when said door is closed. Under such circumstances the mainspring I is under tension. When the door opens, the finger W is removed from the long arm o of the lever V,and said mainspring I is left free to operate. 'Ihe length of this operation and the consequent ringing of the bell are regulated bytwo or more holes, w w', arranged in serieslengthwisc in the short arm o of said lever V. By shifting the cord from one of these holes to another the leverage is correspondingly increased or diminished, and the niainspring I is Wound thereby to a greater or less extent for the purpose above stated.
To lessen the friction between the ringer W and the lever V, the former is provided with an anti-friction roller, X. I also iind it convenient to use a sheet-metal cover, Y, for the clock-Work F, and to make the cord in tivo sections connected by a metal ring, Z. There is no novelty in these devices, however, and they are not at all necessary, although it is desirable to protect and hide the clock-work in some way.
The bell-andalarm operating mechanism Thence IOO herein described may of course l ,ben used` without change with a sliding door or a Window, as well as with the ordinary hinged door which has been shown.
I am aware that it is not new to provide a door with a finger which, when said door is closed, holds an alarm out of action against the tension of a spring, the opening ofthe door leaving the alarm mechanism free to sound.
Io This construction I do not broadly claim; also,
I am aware that the combination of the winding-pulley, winding cord, and clock-work alarm,with tripping devices operated by opening a door, is not broadly new, being shown in a previous patent granted to Anthony and Albert Iske, therefore I do not broadly claim the same.
Having thus described my invention,'what I claim as new, and desire to secure by Letters 2o Patent, is-
1. A lever and a linger attached to the door for holding said lever stationary while the door-ais closed, in ,combinatonwtha windingpulley,the mainspring of an alarm mechanism, and a cord attached to said lever and attached to and wound around said pulley in order that a pull on said cord may wind the alarm mechanism, substantially as set forth.
2. `The bell-crank lever V, having a series `of holes, 'w w', for the purpose stated, the cord
