DOOR-LOCK ATTACHVI ENT.

SPECIFICATION formingpart of Letters Patent No. 705,236, dated July 22, 19102.

Application filed September 20, 1901. Serial No. 75,662. (No model.)

To all whom, t may concern,.-

Be it known that we, ANDREW T. HATFILL and GEORGE B. LEE, citizens of the United States, residing at Decorah, in the county of Vashington, State of Idaho, have invented certain new and usefullmprovements in Door- Lock Attachments and We 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.

This invention relates to door-locks 5 and it has for its object to provide an attachment therefor whereby when the door-knob is operated in either direction to open the door a bell will be rung.

A further object of the invention is to provide a simple and cheap construction wherein by a simple adjustment the knob-spindle will be permitted to turn freely of the lock mechanism to soundthe bell a number of times without operating the look mechanism.

Other objects and advantages of the invention willl be understood from the following description.

In the drawings forming a portion of this speciiioation, and in which like numerals of reference indicate similar parts in the several views, Figure 1 is an edge view of a door equipped with the present invention. Fig. 2 is a vertical transverse section through the bell, the knob-spindle, and the lock mechanism. Fig. 3 is a section on line 3 3 of Fig. 1, the gong being indicatedin dotted lines. Fig. 11 is a transverse section through the knob carrying the striker-pins. Fig. 5 is a view showing the clapper in elevation with the studs or strikers, the door-knob spindle being in section and the positions of the belland its support being indicated in dotted lines.

Referring now to the drawings, the lock mechanism includes the usual yoke 5, which carries the locking-bolt G, the ends of the arms of the yoke being alternately engaged by the tumbler or rocker? to retract' the yoke against the tendency of the springvS. Through the rocker is formed an opening 9, through which is'passed the knob-spindle 10, the central portion of which is rounder to permit of free turning in the opening. In a wall of the opening 9 is formed a seat or recess 11, which is disposed for engagement by a key or feather 12, which is slidably mounted in a guideway formed in the spindle and in the inside knob 13, the feather being held normally and yieldably engaged with the recess or seat by means of the helical spring 11, which encircles the feather and bears at one end against a stop on the feather and at the opposite end against the knob. Thus normally the feather is engaged with the recess to lock the spindle to the rocker, so that the lock will be opened when either knob 13 and l-is operated.

Then the feather is drawn outwardly, however, the spindle turns freely in the rocker, and the lock is not operated. To facilitate outward drawing of the feather, a ring 16 is engaged with its outer end, and when the feather is drawn outwardly this ring may be folded inwardly to lie against the side of the feather and to rest against the end of the knob to hold the feather withdrawn, so that the lock cannot be operated by rotation of either knob. Y

On the inside of the door 17 to which the mechanism is secured is mounted a gong 18 on an arch-shaped support 19, carried by a plate 20, which also carries a stud 21. A spring-plate 22 is engaged at one end in this stud, which is beneath the gong and at the opposite side from the knob 13,and the springplate, which has its edge outwardly, is taken through the arch and outwardly from under the opposite edge of the gong and is passed through a slotted stud 2d adjacent to the gong, the free end of the plate being disposed in the path of movement of a series of studs or strikers 25, mounted upon a disk 26 on the knob 13. Attached to the spring-plate at a point beneath the gong and extending at both sides thereof is a transverse clapper-bar 2S, having heads29, so that when the free end ofthe spring-plate is moved laterally ineither direction it is bowed at the point of attachnient of the clapper-bar to carry one head away from the gong, and when the plate is released the plate in its recovery throws this head against the gong to vibrate it. `Vheu the feather is in engaged position, the knobspindle has only such a degree of rotation as will cause one of the striker-pins to engage first one side and then the other of the free end of the plate to bow it first one way and then the other as the spindle is oscillated.

IOC

Thus in whichever direction the spindle is turned to open the lock the pin will engage, bow, and pass beyond the end of the springplate to sound the gong. When the feather is withdrawn from active position, the spindle turns idly and the striker-pins successively engage the free end of the spring-plate and cause the gong-to sound a number of times for each rotation of the spindle corresponding to the number of pins and without opening the lock.

It will be understood that in the oscillation of the spindle rst one striker-head or clapper-head and then the other will engage the gong; but when the spindle is continuousl y rotated the same head successively strikes the gong.

In practice modifications of the construction shown may be made, and any suitable materials and proportions may bensed for the various parts without departing from the spirit of the invention.

What is claimed is;

1. The combination with a lock mechanism and a knob-spindle for operative connection therewith, of means for throwing the spindle into and out of operative relation to the lock mechanism, a striker carried by the spindle, a gong, a spring-plate lprojecting at one end into the path of the striker and fixed at its opposite end, and a clapper carried by the spring-plate, the gong being disposed for engagement by the clapper when the springplate is released by the striker.

2. The combination with a lock mechanism including a rocker, of a knob-spindle passed through the rocker, a feather carried by the spindle for engagement with the rocker to lock the latter thereto,` means for holding the feather yieldably engaged with the rocker, means for holding the feather in disengaged position, a striker carried by the spindle, and a bellhaving a clapper disposed for operation by the striker.

3. The combination with a lock mechanism and a knob-spindle for operating it, of a striker carried by the spindle, a gong, a spring-plate fixed at one end and extending with its other end beneath the gong and into the path of the striker for operation thereby, stops at opposite sides ofthe spring-plate between the point of attachment of the end of the plate and the striker, and a clapper attached to the plate at a point between the stops and the attached end of the plate.

4. The combination with a lock mechanism including a spindle of means for throwing the spindle into and ont of operative relation to the mechanism, a gong, a spring-plate attached at one end beneath the gong and projecting with its opposite free end therefrom, strikers carried by the spindle for engagement with the free end of the plate, stops at opposite sides of the plate at a point between its ends, and clappers carried by the plate at a point between the stops and the attached end of the plate for engagement with the gong.

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