VIVIAN B. FULLER, OF INDIANAPOLIS, INDIANA.

AUTOMATIC WINDING DOOR-BELL.

SPECIFICATION forming part of Letters Patent No. 755,568, dated March 22, 1904.

Application filed May 11, 1903. Serial No. 156,591. (No model.)

To all whom it may concern:

Be it known that I, VIVIAN B. FULLER, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Automatic Winding Door-Bells, of which the following is a specification.

This invention relates to improvements in door-bells in which a gong is sounded by blows from a spring-actuated hammer; and the object of the invention is to provide means by the opening and closing of the door for auto- "matically winding the spring.

The object also is to provide a regulative meansor governor which will prevent the overwinding of the spring.

I accomplish the objects of the invention by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a detail in horizontal section of a door and its casing, showing my invention applied thereto; Fig. 2, a front or outside View of the ringing device with the gong and outer plate of the frame removed to reveal the inside mechanism; Fig. 3, a back side view of Fig. 2; and Fig. 4:, a section on the dotted lines 4: 4 of Figs. 2 and 3.

I Like characters of reference indicate like parts throughout the several views of the drawings.

5 is a door, 6 the door-casing, and 7 the hinges by which the door is hinged to the casing.

8 is a spindle or short shaft which is mounted in a frame comprising a pair of plates 9 9, (see Fig. 4%,) connected by posts 10. This frame is secured to a base 11, which is fastened by screws 12 to the door. The spindle 8 has the sleeve 13 mounted loosely on its inner end and extending through the inner plate 9, so as to receive'the ratchet-wheel 14, which is mounted in a fixed manner thereon. Fastened to the side of the wheel 14: is the drum 15, within which is the band-spring 16, the inner end of which is fastened to the spindle 8 and its outer end to the inner wall of the drum, as shown in Fig. 4:. Mounted loosely on the shaft 8 is the cog-wheel 17, which is separated from the drum and spring by the washer-plate 18. Mounted in a fixed manner on shaft 8 is the ratchet-wheel 19,

the spindle 8, pawl 20, and ratchet-wheel 19, I

permitting the proper rotation.

22 is a pinion mounted on a. shaft supported by the frame. The pinion is driven by engagement with wheel 17, and mounted on the same shaft with said pinion is the escapementwheel 23, which is controlled by the anchor 24:, mounted on a suitable adjacent shaft which also carries the rod 25, which terminates with the hammer 26. The latter is vibrated by the above mechanism, thereby striking and ringing the gong. A longitudinally adjustable shaft having the disk 27, said shaft being held by spring 28 in normal position with said disk under hammer-rod 25 to prevent the vibration of the latter, is moved by push-rod 29, terminating with a suitable button, so as to release the hammer-rod.

I will now describe the means for winding the spring 16 by the swinging of the door. The action of the spring 16 on wheel 14 is resisted by the spring-actuated pawl 30; but obviously by rotating the wheel 14: in the direction permitted by its pawl drum 15, to which one end of spring 16 is fastened, will be rotated, so as to wind up the spring.

31 is a drum mounted in a fixed manner on sleeve 13, to which it is secured by screw 32. The outer end of the sleeve has the annular flange 33, between which and the drum 31 is the ratchet-wheel 34:, having a hub on one side which is extended into the bore of the drum. This hub is mutilated on one side to receive a post 35, seated in sleeve 13. The

adjustment of the wheel 3A on said sleeve is.

limited by contact of the post with the ends of the hub mutilation. The diameter of said hub is enough less than that of the bore of the drum to allow the introduction of the coiled wire spring 36 between them. The in- 100 ,7 in c, i ,1 I

ner end of this spring is secured to the drum 31 and the outer end to the ratchet-wheel 34. (See Fig. 4.) When the tension on the bandspring 16 is less than thetension of spring 36, a rotation of the ratchet-wheel 34 will in like measure rotate the drum 31, and thence through sleeve 13, ratchet-wheel 14, and drum the spring 16 will be wound, the ratchetwheel 34 and drum 31 acting through spring 36; but when the tension of spring 16 exceeds that of spring 36 the rotary movement of the ratchet-Wheel 34 will not move the drum 31; but the wheel will oscillate within the limits fixed by its mutilated hub and post 35. The desired maximum tension of spring 36 is given at the time of assembling the wheel and drum on sleeve 8.

Mounted upon the drum 31 is an additional drum 37 having an annular channel in which is seated the coiled wire spring 38. One end of this spring is fastened to the plate 9 of the frame and the other end to the drum 37 Pivotally secured to the drum 37 is a pawl 39, which is pressed by spring 40 into engagement with the teeth of the ratchet-wheel 34. Also secured to the drum in a rigid manner is the lever 41, to the outer end of which a chain 42 is fastened. The door is mortised in the manner shown in Fig. 1 to receive the above-described winding-drums, and leading into this mortise from the back edge of the door is the bored hole 43, through which the chain 42 is threaded in the manner shown, and the end of the chain is made fast to the door-frame by staple 44 or other suitable means. Preferably the mouth of the bore will be reinforced with a metal thimble 45 to prevent wear. 7

The opening of the door drawson the chain, thereby shifting lever 41 and moving drum 37 Pawl 39, by engaging ratchet-wheel 34, moves the latter wheel, which through spring 36, drum 31, sleeve 13, wheel 14, and drum 15 winds spring'16 till tension of latter reaches that of spring 36, when the continued opening of the door oscillates lever 41 and its drum and ratchet-wheel 34 without further winding of spring 16.

Spring 38 in drum 37 is for the purpose of returning the drum and lever 41 to first position after release by the chain.
