To all whom itmay concern.- g

vBe it known that I, RICHARD H. Nonnls, of Pat-A Same.

Figure 3 'is an end View, partly in section, of the same.

Similar' letters of reference indicate corresponding parts.

This invention relates to spooling-registers, and consists in certain improvements thereon, which' will be specified hereinafter.

The invention consists in so hanging the frame which carries the main train of wheels, that one motion on a spring knob will at once release them, and throw the train and the hands moved by the same hack to zero. Thereby a new start at counting can he take whenever desired. v

A, in the drawing, represents a cylindrical case of suitable size. On its face is arranged a dial-plate, B, which has figures marked near its edge to denote tl number of yards that are measured.

O is a shaft fitted through one side of the 'case A, andL provided with a wheel, D, at itsonter end. The edge of this wheel is grooved', to'receive the thread to he measured. y

From the ease projects a loose frame, E, which has two loops, a. a, through which the thread is passed.

Between the loops a is suspended from the thread a weight, F, which serves as 'a brake.

In case the thread breaks or becomes slack, it drops between the edge of the wheel D and a fixed` post, l), and prevents the further motion of the wheel.

0n the inner end of the shaft 0 is mounted a worm, o, which meshes' "into the teeth of a wheel, d said wheel being, together wit-h a pinion, e, that is connected with it, mountedupon a vertical arbor, L'th'at projects from the. bottom of the ease.

Within the case A is pivoted by a pin, g, a frame, G, which carries the main train ofwheels, of which one (H) is held in gear withthe pinionc, as in fig. 1.

A spring handle, I, 'projects froln the 4frame G,

through the side of the case A. When the knob on' the end of thehsndle is pushed, it will move the frame G so as to cariythe wheels H and e out of gear.

The wheel H isfhung loose on its shaft h, but couneetedbypawl und ratchet i with the same, in such manner that it vmay turn iu one direct-ion'loose on the shaft, while in the -other direction it will always rcvolve the same with it. '.Ihe arrow -1, iig. 1, indicates the direction in which the shaft h is always in gear with H.

0n theshaft h. is mounted a pinion, j, which meshes into the teeth of a wheel, k, whose shaft Z is hung on the frame G. A main-spring, m, tends to rotatethe shaft l and wheel lk in the directionfof the arrow 2.

.A wheel, n, on the shalt Z, meshes into the teeth of a wheel, o,v hung loose on the shaft h. One hand, p, is fastened to the shaft h, and one, q', upon the tubular shankof the wheel o, both hands being above the dial-plate.

J is a gong-bell fastened to the side of the case A. L is the clapper for striking the same. The clapper is fastened to a ,spring rod, r, which holds it off the hell, but which hasa projection ear, s, above the wheel H. Ou the wheel H is secured a cam, t, which once during every revolution reaches the ear s and moves the same, so as to wind the spring on the clapper-stem,

thereby, when it releases the ear, applying the clapper and sounding the alarm.

M is a curved wire of peculiar form. It is pivoted to the frame G, and has one arm, u, above the face of the wheel k, and another arm, V, above the face of the wheel H. A spring, w, draws the latter arm away from a pin, z, that is fastened to a bar projecting from the shaft h.

rlhe operation is as follows:

The thread to be spooled is wound once around the i wheel D, and passed through the loops a and weight F, as indicated in fig. 2. As it isdrawn along it will rotate the wheelD and shaft C, and the motion will, by the worm c and wheels d e,- be transmitted Vto H, by which it is also transmitted to It and all the other wheels. The wheel H is so geared that it will make one revolution while hundred yards pass over the wheel D, and the wheel o is geared so that it makes vone revolution during the passage of every thousand yards. The hand p will, therefore, show on the dial-plate the number of yards spooled, up to one hundred, while the hand q will on an inner scale show them up ,to one thousand. Whenever ahu'ndred yards has been measured, the elapper is moved by the cam t, andthe bell' J struck.- While the apparatus is thus in motion, the spring -m is being wound up by the wheel k, and it will,

as soon. as the wheel His thrown olf theI pinion c by the pusher I, unwind rapidly, and move all the wheels back to their oliginal position and the hands-to zero.

In order' to eii'ect an accurate stop, the wire'M is provided. Just in reaching the zero position,'a pin, y, on lf, strikes the arm u, and moves thereby'the other arm V in the way ofthe pin Z on H. Thus both wheels, k and H,' are arrested at the proper point.

I v'Phe wheel H is, by the pawl and ratchet, held so fast that it will in every direction move with the shaft h. Only if the latter is locked by the lpin z and arm V,

thewheel H may be turned independently opposite to the arrow 1, to bring the cam tin play at the desired time. To thus set the cam, a key may be applied to the arbor j, as in fig. 2, to wind the wheels,

In or'der to prevent the overwinding of the spring m, and the passage of the hands beyond the 1,000, or other largest figure, therein a. pin, z, on the flame' G',

against which the pil' y will force the arm u of thev wire M, to lockthe wheel k and prevent further aetion. The wheel d .is hung looseon the shaft j; al-

though tight enough to move together with the same. 1

1. An instrument for automatically recording and vannouncing a given length of thread when wound upon the spool, consisting essentially of a dialplatevwith yard notations thereon, the grooved thread-wheel D, th'e frame E having thread-loops a a, weight F, the worm c, themovable frame G holding main train of wheels, spring handle I, shaft h having pawl and ratchet connected therewith, cam-wheell H and e'ar s, the gong J, and elapper L, all arranged, connected, and operated as set forth.

2. The combination of wheel 1c having. pin y thereon, wire M, springen, and pin a: on 'frame G, with the driving spur-wheel H having pin z thereon, connected and disconnected with the worm-shaft, as set forth, to alternately wind up and unwind the registering mechanism in the manner described.
