WINDING AND SETTING ATTACHMENT FOR CLOCKS.

SPECIFICATION forming part of Letters Patent No. 381,603 dated April 24, 1888.

Application filed July I, 1887. Serial No. 243,068. (No model.)

To all whom, it may concern:

Be it known that 1, JOHN ZELLY, a citizen of the United States, and a resident of Cincinnati, in the county of Hamilton, State of Ohio, have invented certain new and useful Improvements in Winding and Setting Attachments for Clocks, of which the following is a specification.

The several features of my invention and the advantages arising from their use conjointly or otherwise will be apparent from the following description.

In the accompanying drawings, forming part of this specification, Figure 1 is a front elevation of the lower part of a hanging clock provided with my improvements. Fig. 2 isa side elevation, on an enlarged scale, of part of the mechanism shown in Fig. 1. Fig. 3 is an enlarged view showing the winding-stem and upper part of the operating-rod. Fig. at is a rear view of a standing clock embodying my invention, part of the rear plate being broken away. Fig. 5 is a central sectional elevation of the clock shown in Fig. 4. Fig. 6 is a side elevation, on an enlarged scale, of the device for setting the hands, as shown in Fig. 5. Fig. 7 illustrates a modification of-the device for setting the hands. Fig. 8 is a view of a portion of the front plate of the clock. Fig. 9 illustrates the construction of the operatingrod.

My device may be attached to any form of clock. For hanging clocks the handle for winding and setting the clock projects downward. For standing clocks the mechanism is modified so'that the handle for winding and setting projects from the face of the clock. It has also been necessary to adapt the mechanism to clocks provided with aspring and barrel and those having aspring without the bar-- rel. This latter form of mechanism is also applicable to clocks provided with weights. In clocks having a spring without a barrel thespring is wound by and in turn imparts its motion to the arbor which passes through its center. The device shownin Fig. l is adapted for use with such a clock.

A represents the central arbor of the timespring and B the central arbor of the striklug-spring.

0 represents the front plate of the clock.

011 each of the arbors A and B is a loose toothed wheel, (respectively designated A B,) both of which wheels gear into the idler D. The ratchets A B? are rigidly attached to the arbors A and B and rest against the faces of the wheels A B. The pawls ab are attached to the wheels A B, and areheld into the ratchets by the springs a b. Each of the pawls a b terminates in a long tail, a b curving around the arbor. The idlerD has rigidly attached to its face the-beveled gear-wheel D, which meshes with the beveled gear-wheel D on the top of the stem E. The stem E is supported in suitable brackets, e e, projecting 6 from the face of the plate 0, and terminates in the squared end 0, which is larger in diameter than the stem above it. The stem E is received into the upper end of the rod F. The upper end of the rod F is provided with a chamber, j, which is large enough to allow the rod F to be rotated about the enlarged head 6 of stem E. The entrance f of the chamber f is contracted and squared, so as to fit the head 6. The rod F, projecting downward, 7 passes through an opening in the bottom of the case, (not shown,) and the friction there is sufficient to support the rod F.

The yoke G is attached tothe plate O by the pin 9, which passes through the slot 9 this arrangement allowing the yoke G to slide up and down on the plate O a limited distance. The arms 9 0f the yoke G, when raised, impinge against the tails a b of the pawls a b, liberating the pawls from the ratchets. The yoke G is provided with the flange 9, through which the rod F passes. The eollarf is rigidly attached to the rod F, and the spiral spring f rests on it and has above it the sliding collarf. The rod F isprovided at its upper 0 end with the gear-wheel F. The stem H is placed behind the idler D, and is provided at its ends with the gear-wheels 7th, the stern being supported in suitable bearings projecting from the 'late 0, so that it can be rotated. 9 The whee h meshes with the crown-wheel h, which is mounted on the arbor h of one of the train of wheels which moves the hands.

The mode of operation of the device is as follows: When the parts are in the position :00

shown in Fig. 1, the clock is ready for winding. On rotating the rod F the stem E is similarly rotated, and through the bevel D D and idler D imparts motion to the wheels A B. If the rod F be rotated to the right, the wheels A and B will be turned in the direction of the arrows. The effect of this movement will be to wind the time-spring; but the striking-spring will remain unaffected, the pawl b slipping over the ratchet B". WVhen the rod F is rotated in the opposite direction, the striking-spring will be wound. These springs may be wound either by a succession of short oscillatory rotations in opposite di-- reetions, or each spring may be completely wound separately. In unwinding the springs turn the ratchets in opposite directions, which motions would mutually stop each other if the wheels A B were left connected to the ratchets. To prevent this stoppage, they are disconnected by raising the yoke G, whose arms striking against the tails of the pawls a I), throw these pawls out of gear with the ratchets. The yoke G is raised by pushing the rod F, which causes the collarf to strike against the flange 9, thus raising the yoke. The parts are so adjusted that raising the yoke G suffi ciently to liberate the pawls a I) does not compress the springf.

When it is desired to set the hands of the clock, the rod F is pushed up until the wheel F meshes with the wheel h. In this position the head e is received in the chamberf, and when the rod F is rotated no effect on the winding mechanism is produced; but this rotation of the rod F serves to put in motion the mechanism for moving the hands. In setting the hands the spring f is compressed and serves to return the rod .F to its proper position after the hands are set.

It is sometimes desirable to have the rod F quite long-in fact, several feet long. To accommodate this length and to adjust it to any desired length, it is preferably made in sections, which telescope together and are fixed in position by cross-pins, as illustrated in Fi 9.

In the modification shown in Figs. 4, 5, and 8 the stem E is attached directly to the idler D and projects forwardly through the front of the clock. The spring I surrounds the stem E, and is headed by the movable collar l. The rod F is much shorter in this form of device than in the other. Near its end it is provided with the annular groovef and when it is pushed down on the stem E, compressing 'the spring I, the lever Jis forced into the groovef by the springj and holds the rod F in its position. In this position of the rod F the enlarged head 0 of the stem E is received in the chamberf, and, turning the rod F, produces no effect on the clock mechanism. lVhen the lever J is raised, the rod F is released and thrown forward by the spring I. It may now be adjusted in the position shown in Fig. 5, with the contracted squared opening f engaging the head 6 when it is in position for winding the clock, which operation is the same with this form of device as with the other.

The device for setting the clock consists in providing the minute-hand arbor K with teeth and the rod F with the crownwheel L. To set the hands it then only becomes necessary to force the rod F down until the crown-wheel L engages with the teeth 7c, when by turning the handle of the rod F the hands may be set as desired. The device for setting the hands may also be arranged as shown in Fig. 7, where a crown-wheel, k, is attached to the minutehand, and the crown-wheel L is correspondingly enlarged in diameter. \Vith this arrangement it is necessary to have the minutehand rigidly-secured to the arbor K.

Then the springs are surrounded by drums M, as shown in Fig. 5, they are wound, as usual, by rotating the central shaft; but in unwinding the motion of the spring is imparted to the barrel, and not to the shaft, which latter is held stationary by the ratchet N. It is therefore unnecessary in this form of device to detach the ratchets A B from the wheels A B.
