CLOCK-WINDING MECHANISM SPECIPICATION forming part of Letters Patent No. 366,429, dated July 12, 1887.

Application filed June 2, I886.

To ctZZ whom/it may concern.-

Be it known that I, ABE RoBINsoN, of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Olock-WVinding Mechanism, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved automatic winding mechanism for clocks actuated by springs.

ating a train of gear-wheels connected with the spring-barrel 0f the clock mechanism, and of an automatic wind-wheel-lock.ing device;

The invention also consists of various parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying. drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is an elevation of my improvement, parts being in section. Fig. 2 is a bottom view of the same. Fig. 3is a rear View of the locking device in its locked position. Fig. 4 is a similar view of the same in an unlocked posi tion. Fig. 5 is a crosssection of the same on theline 00 a: of Fig. 4. Fig. 6 is a face View of the transmitting-wheel of the locking device. Fig. 7 is asimilar view of the same from the other side. Fig. 8 is a central section on the line 11g of Fig.2. Fig. 9 is an inner face view of the transmitting wheel for the striking mechanism, and Fig. 10 is an enlarged detail plan view of the locking device.

Awind-wheel, A, of any approved construction,is mounted in a frame, B, attached to the casing C, in which is mounted, in a suitable frame, D, an ordinary clock mechanism actuatcd by a coil-spring, one end of which is at tached to the barrel E, the other end being attached to the spindle F, which forms a bearing for the barrel E, which operates the clock mechanism in the usual manner.

The casing O is preferably made in two parts, separated by a partition, 0, so as to establish a flue, 0 from which the air or draft passes through the wind-wheel A and rotates the' same, and then the air passes into the flue or 0 shaft connected with the rear end of the frame B of the wind-wheel A.

The wind-wheel A is mounted on a shaft,

The invention consists ofa wind-wheel actu- I Serial No. 203,920. (Modem A, which has its'bearing on the casing 13 and the partition 0, passing through thelatter and being provided on its inner end with a crankarm, G, which connects loosely with the arm H, attached to the spindle I, having its hearing on the swinging frame J, pivoted on a stud, J, attached to the plate J mounted on the'frame D, carrying the clock mechanism.

On the spindle I is secured a pinion, 1, which meshes into the gear-wheel I", attached to a spindle, 1 having its bearing in the swinging frame J, and the spindle l is provided with the pinion I, which can be thrown in and out of gear with the gear-wheel K, which is one of a train of gear-wheels connected with the gear-wheel L, mounted on the spindle F, which forms a bearing for and is connected with the spring-barrel E. The gear-wheel L meshes into the gear-wheel M, secured to the spindle M, which carries loosely the gear- Whecl M, operating the striking mechanism of the clock in the usual manner. To the gearwheel M is attached one end of a spring, M", one end of which is secured to the ratchetwheel M, also placed loosely on the spindle M and engaging a pawl, M mounted on the frame D, carrying the clock mechanism. The ratchet-wheel M is fastened to the spindle M and engages aspring-pawl, M pivoted on the ratchet-wheel M".

On the gear-wheel L is mounted a trans verse spindle, N, which carries onone on one face of the wheel L, a cam, N, and, the other end,on the other face of the wheel L,carries a segmental gcarwvheel, N, which engages with a stud, E, attached to thespringbarrel E, so that for every revolution of the wheel L the segmental gear-'wheel N is turned the distance of one tooth and the cam N is turned the same distance.

On the cam N rests the collar O, placed loosely on' the spindle F, which collar is raised or lowered by the action of the turning of the cam N. On the collar 0 rests the free end of the spring O, secured to the plate J and the free end of the spring is provided with the gages with the swinging frame J. 'To the latter is secured a spring-catch, Q, the free bent end of which engages a hook, 0 formed on the plate 0". A pin, 0, projects from the upper end of the plate 0", and is adapted to engage with an arm, J secured to the swing ing frame J at its pivoting on the said stud J. The motion of the swinging frame J is limited by the stop-pin It, projecting from the plate J into a notch, J.

The lever S is pivoted to a stud, S, secured to the swinging frame J, projects through a slot in the partition O,and has its bearing in the plate S attached to the said partition 0. The outer spring end of the lever S is out of contact with the wind-wheelAwhen the clock is to be wound up, and is in contact with the wind-wheel A, and prevents the turning of the same after the clock is wound up.

The operation is as follows: WVhen the windwheel A is caused to rotate by the air passing up through the flue G the several parts of my improvement are in the position shown in Figs. 1, 2, and 8--that is, the swinging frame J is so placed that its pinion I meshes into the gear wheel K of the train of gear wheels which rotates the gear-wheel K and the pinion 1, deriving its own rotary motion from the wind-wheel A,whieh imparts a rotary motion to the spindle I by the crank-arm H, and the spindle transmits its rotary motion to the said pinion I, by means of the pinion I, meshing into the gear-wheel 1 mounted on the same shaft 1 with the pinion 1. The train of gearwheels K imparts a rotary motion to the gearwheel L in the direction of the arrow a, (see Fig. 3,) and the mainspring, being attached by one end to the barrel E and by the other end to the spindle F, carrying the wheel L, is wound up, the barrel E remaining nearly stationary, only driving the clock mechanism, which is not interfered with as long as the winding up lasts. The gear-wheel L also turns the gear-wheel M on the spindle M, but does not turn the gear-wheel M,which operates the striking mechanism as the pawl 1W glides over the ratchet-wheel M, (which is also turned by the rotation of the spindle M,) and consequently does not move the gear-wheel M as long as the winding up lasts.

For every revolution of the gear-wheel L the pin E',att aehed to the spring-barrel E, to rns the segmental gear-wheel N the distance of one tooth, and consequently turns the cam N the same distance, so that the collar 0, resting on the cam N, is forced sidewise by the same, and when the mainspring is entirely wound upin the barrel E the collar 0 is in its uppermost position on the cam N and forces the free end of the spring 0' outward, which releases the spring Q, attached to the swinging frame J, from the notch 0", and the lever]? is moved in the direction of the arrow 1) by the inclined slotO", so that the spring P throws the swinging frame Jinto the position shown in Fig. 4, whereby the swinging frame J disengages the pinion I from the gear-wheel K of the train of gear-wheels connected with the gear-wheel L. The arm J then rests on the lug O, and prevents the voluntary return of the swinging frame J. Thissudden movementof thesw1nging frame J forces the arm S to move in the direction of the arrow 0, the plate S being fulcrumed, so that the spring end of the arm S engages with the wind-wheel A and pre vents its further rotation. The mainspring, attached to the barrel E and the spindle F, causes the latter to rotate in the inverse direction of the arrow a, as soon as the said spring is wound up, as above stated, and the wheel L is then also rotated in the same direction with the spindle F, and thereby reverses the motion of the segmental gear-wheel Nand the cam N, so that the collar 0 and the free end 0" of the spring 0 are gradually drawn inward until the cam is in its innermost position when the mainspring is nearly unwound. Then the lug 0, moving inward with the free end of the spring 0, releases the arm J and the inclined slot 0, and the free end 0' ofthe spring 0 forces the lover I? back to its former position, so that the spring arm l throws the swinging frame J to its former position, (shown in Fig. 3,) whereby the lever S disengages the wind-wheel A, and thereby the latter is free to rotate, and the pinion I again meshes into the gear-wheel K of the train of gear-wheels which imparts motion to the gear-wheel L and the spindle F in the direction of the arrow a, and the winding of the mainspring again commences, as above described. The springQengages with the notch 0 and holds the swing ing frame J in a locked position. \Vhen the mainspring is unwound, the wheel L operates on the gear-wheel M" by means of the gearwheel M, turning the spindle M, which rotates the ratchet-wheel M, and as the pawl M is now in active engagement it turns the ratchet-wheel M", to which the pawl M is pivoted, and first compresses the spring M to its limit, and then turns the gear-wheel M, which operates the striking mechanism.

It will be seen that when the motion of the gear-wheel L is reversed, so as to wind up the mainspring, the compressed spring M" keeps the gear-wheel M" in motion until the mainspring in the barrel E is wound up again, as the pawl M holds the ratchet-wheel M" in position, so as to permit the spring M to act on the gear-wheel M and, consequently, on the striking mechanism, which is not interfered with whether the mainspring is wound up or unwound.

The movement of the swinging frame Jmay be utilized in many ways to lock or unlock the wind-wheel A as, for instance, a double door attached to the frame 13 could be opened or closed by the movement of the swinging frame J, which opening and closing of the door would cause a stopping or running of the wind-wheel.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1.
