SPECIFICATION forming part of Letters Patent No. 623,158, dated April 18, 1899.

Application filed June 20, 1898. Serial No. 683,933. (No model-l ,To @ZZ whom, t m/cty concern:

Be it known that I, AUGUSTUS G. J Acces,- residing at Jonestown, in the county of Goa homa and State of Mississippi, have invented certain new and useful Improvements in XVinding-Indicators for Clocks, of which the following is a speciiication, reference being had therein to the accompanying drawings.

This in vention relates to winding-indicators for clocks.

The object of the invention is to produce an indicator which can be readily attached to clocks of ordinary construction and which will show a signaling device when the clock is nearly run down and may also have a mui'ller for the striking apparatus ofthe clock. The visibleindicator or signal is preferably a folding fan which may fold into small compass and can bespread with very small eX- pensc of power. A

The 'improvement consists in certain constructions and combinations substantially as hereinafter described.

Figure 1 is a ront elevation of aclock-iiront partly broken away to show the general arrangement of the indicator iu the position in 'which the indicator is inoperative. Fig. 2 is a similar View showing visible indicator and mufiler operating on the bell, as when the clock has nearly run down. Fig. 3 is a front elevation of the fan and its operating wheel or pulley and connections. Fig. 4 is a front elevation of the signal-operating mechanism and part of the frame and other portions of a clocleniovenient. Fig. 5 is an edge `view of the signal-motor attachment as applied to a clock-framel The attachments which I make for connection to a common clock are the motor part, shown in Figs. Ltand 5, and the fan, connected to a wheel and axle, Fig. 3, the parts being connected by an operating-cord, as indicated in the other figures.

Most clock-cases, as 1, have a molding, as 2, at the top of the casing, behind which there is a recess not visible directly from the front of the clock. This permits the attachment of my fan-shaped indicator 3, which when folded down will generally be invisible from the front of the clock, or if visible will appear merelyas a fan lying on the top of. the clock-case.

The narrower end of the folding fan 3 is at tached to a tape 4t, which partially surrounds and is attached to an axle 5,.and one of the fan-sticks 6 is attached to a base-piece 7, as by a cord 8. The axle 5 is supported on suitable standards or brackets 9 from the base, and theaxle has a wheel or pulley 1l rigidly connected thereto.

The partial rotation of shaft 5 in the direction of the arrow, Fig. 3, will spread out the fan, as indicated in Fig. 2, and the release of said pulley will permit the fan to fall back into the position of Fig. 3 or a lower position on base 7, either by the weight of the fan or by its tendency to close itself when made of such material that the fan tends to close, or by reason of a weight, as 13, attached to wheel l1, or any usual means for closing a fan. The cord 8 prevents fan-stick 6 from rising much beyond a position about parallel with the base 7 and a little above the same.

The base 7 can be attached to the top of the clock, as by screws, and a small hole through the top of the clock-case permits the passage of cord 14 to the interior of the clock behind the dial. Oord 14- is attached to the wheel or pulley 11, and a hole in the clockcase large enough to pass cord 14 is all the cutting found necessary with mostclocks in making my attachment. The fan can be opened or spread and closed 0r folded very easily, and when spread preh sents a large surface, which may have words or ornamental designs thereon. I am aware that signals have been used to show that clocks have nearly run down; but none of those with which I am 4familar can be made to show so large a surface with so little expenditure of power 'as my fan-signal.

The gearing or mechanism for operating the fan-signal I attach to the clock-movement frame. A convenient form of attachment is shown, wherein piece 2O is a metallic strip about as wide as one of the bars of a common clock-frame, and said strip or piece 2O has an integral hook 21 near its end and at the side, so that said hook will extend behind the bar 16 of the frame. The piece 2O has-a bracket 22 isneedful to attach the gearing to a common roo mechanism detachable.

clock-frame is to hook the hook 2l about the clock-frame and apply the one-tooth gear to the winding post. Of course attachment could be made to other forms of clock by slight changes. The whole mechanism might be applied to other forms of clock by slight mechanical changes or directlyand permanently to the clock-frame, but I prefer to'have the To base-piece 2O I attach the gear-wheel 30, said gear having teeth with which the onetooth gear 23 engages, either in winding the clock or as the winding-post moves. The gear 30 maybe provided with a stop-tooth to stop the clock when it shall have run down. The teeth on gear 30 are of such number as will about make a rotation of gear 30 while the clock is running down.

On the disk-face of wheel SO I attach a disk 3l, provided with a broken-face ring`32 or a projection from the body of the disk in form of a broken ring. The disk 3l has a curved slot 33 therein, and a set-screw 3i in this slot serves to adjust the disk 3l relatively to wheel 30, so that the break in ring 32 may be adjusted circumferentially on gear 30 to permit the device to be made operative at a little less than a rotation of gear 30, say about twentytwo, twentythree, or twenty-four hours in a one-day clock or at seven or seven and one-half days in an eight-day clock.

A bentlever is supported on a pivot, as 3G, which pivot is supported on a suitable bracket, as 37, connected to piece 20. An arm 38 of this lever rests against the broken ring 32 as gear 30 rotates, taking disk 3l with it; but when the break in the ring moves opposite the end of this arm 3S the arm 3S swings through the break in the ring under the iinpulse of weight 39, attached to long arm of lever 35. This depression of the weight 39 draws on cord Il and spreads the fan at the top of the clock. At the same time an arm i0 of lever 35 is swung against the bell or sounderaf) of the clock and the bellis muffled. The spread fan and muffled bell are indicated in Fig. 2. The upper end of arm 38 has a hooked end with its outer under surface inclined, as indicated in Fig. 5. The arm 3S is slightly elastic.

Vhen the indicator 3 is spread, the clock may run until it runs down, but the spread fan will show that winding should be attended to, and the muliied bellwill indicate the same fact.

The direction of movement of gear 30 in running down is shown by the arrow, Fig. l. In winding the clock the gear 30 rotates in the direction indicated in Fig. 2. The screw Stby such rotation engages the right-hand side of lever-arm 3S and swings said lever to the position of Figs. l and at. The hooked end of lever 3S will ride over ring 3251i moving out, but will engage the outerside of said ring and will be prevented from swinging in toward the center of the ring except through the break in the ring.

The weighted arm of lever 35 may be in itself enough to spread the fan without an additional weight. rIhe winding of the clock permits the folding of the fan and removes the mufiie from the bell.

It must be understood that in many details of my mechanism modifications may be made without departing from the spirit of the invention. I believe the invention to be as broad as the claims herein.

What I claim isl. A fan indicator for clocks, consisting sentially of a folding fan, a shaft to which the fan is connected, so that the fan is spread by the partial rotation of the shaft in one direction, and allowed to close by the partial rotation in reverse direction, a supporting-base by which the fan and shaft may be attached to a clock-case, and means for connecting the shaft to the clockmovcment to be actuated thereby. l

2. In combination with a clock-case, a fansupport connected to said case, a folding fan on said support, a shaft connected to the fan to spread the same and a pulley on said shaft, a cord connecting said pulley to the clockmovement, and means for closing the fan, all combined substantially as described.

3. In a clock winding-indicator, the basepiece 20 having means for attachment to the clock-movement frame, a single-tooth wheel supported on said base-piece and engaging the winding-post of the clock, a gear actuated by said single-tooth wheel and carrying a broken ring-bearing, and a lever having' an arm in position to swing through the break in the said ring, said lever connected to and operating a visual signal, all combined substantially as described.

Lt. In a clock winding-indicator, the base piece having means for attachment to the movement-frame,a gear-wheel carried by said base-piece and driven from the clock-movement, the broken ring carried by said gear, a lever suitably supported and having an arm in position to bear against said ring and to swing through the break thereof, and a mullle connected to said arm and in position to IOO IIO

muilie the striking apparatus of the clock when the lever moves through the break in the ring, all combined substantially as described.

5. In a clock winding-alarm, the combination with the clock-movement, of a visual signal actuated to indicate the need for winding the clock, and a inutile connected to the visual-signal-actuating mechanism and actingon the striking mechanism of the clock simultaneously with the display of the visual signal and for the same purpose, substantially as described.

G. In a clock winding-alarm, the combination with the clock-movement, of a gear-wheel driven from said movement, a broken ring or bearing adj ustably connected to said gear, a lever having an arm bearing on said ring in position to swing through the break thereof,

normal position by the Winding of the clock, io

all combined substantially as described.

In testimony whereof I aiTiX my signature in presence of two witnesses.
