CRIME-CLOCK.

Specification of Letters Patent.

Patented May 6, 1919.

Application filed January 10, 1918. Serial No. 211,181.

T 0 aZZ whom it may concern Be it known that I, JAMES B. PHILLIPS, a citizen of the United States, residing at Grand Rapids, county of Kent, State of Michigan, have invented certain new and useful Improvements in Chime-Clocks. of which the following is a specification.

This invention relates to improvements in chime clocks.

The main objects of this invention are:

First, to provide an improved chime attachment for clocks which may be quickly and easily installed in connection with the clock mechanism as an independent unit.

Second, to provide an improved chime clock which is comparatively simple and compact in structure.

Further objects, and objects. relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which:

Figure I is a detail rear view of a structure embodying the feature of my invention, only ortions of the rear plate and the driven spin le of the clock movement being shown, the casing being omitted.

Fig. II is a detail plan view of the mechanism shown in Fig. I, the clock movement being mainly omitted.

Fig. III is a vertical section on a line corresponding to line 3-3 of Fig. II, showing the mechanism in its initial or first position.

Fig. IV is a detail section similar to that of Fig. III, showing the parts in another position.

Fig. V is a. detail section similar to that of Fig. III showing the mechanism in striking or chiming position.

Fig. VI is a detail section similar to that of Fig. III, showing the mechanism advanced one step from the position shown in Fig. III.

Fig. VII is a detail section on a line corresponding to line 7-7 of Fig. II.

Fig. VIII is a detail view, partially in section, on a line corresponding to line 88 of Fig. II, showing details of the chime proper.

Fig. IX is a detail section on a line corresponding to line 99 of Figs. I and II.

Fig. X is a view of the actuating drum extended.

In the drawing similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing, 1 represents the rear movement or frame plate of a clock movement. The details of the clock movement are not shown as they form no part of this invention. The clock movement is provided with a driven minute hand spindle 2 on which I mount a star wheel 3 for actuating the releasing or trip lever I. This lever, in the structure illustrated, is formed in sections 5 and 6 mounted upon a block 7 pivoted at 8 on the clock movement plate 1.

A set of chime bars or sound tubes 9 are mounted on the bracket 10 which is in turn mounted on the rear casing wall 11.

The hammers, designated generally by the numeral 12, are pivoted on a spindle 13 projecting from the rear frame plate 14 of the chime movement.

The hammer actuating drum is mounted on the shaft 15 disposed parallel to the spindle 13. This drum is formed of a plurality of disks 16 having tappets, 17 thereon adapted to engage coacting tappets 18 on the ham mers as the drum is revolved actuating the hammers as indicated by dotted lines in Fig. VIII. The tarppetsare spaced as desired on the disks, the disks preferably being adjustable on the shaft 15 so that the tappets may be brought into desired relation. In Fig. X I show the disks unrolled in order to disclose the relation of the tappets illustrated. The means for adjustably securing the disks upon the shafts are not shown as they form no part of this invention.

The shaft 15 is driven through a suitable spring mechanism, designated generally by the numeral 19, the shaft 15 being geared to the power spring. The shaft 15 is provided with a stop disk 20 having stop notches 21, 22, 23 and 24 therein. A stop dog 25 is mounted on the pivot 26 to coact with this stop wheel. Below this stop dog is a release member 27 mounted on the pivot 28 and projecting to beengaged by the release lever actuated by the star wheel. The stop notches 21, 22, 23 and 24 are spaced differently on the stop wheel so as to secure the actuation of the chime for different lengths of time, for dilferent periods, such as the quarter, half, three-quarter and hourly periods. vAs indicated in Fig. X, ta-ppets are arranged so that the sound bars are" struck in difierent order and also a larger number of strikes for each succeeding period during the hour,

As the movement of the star wheel is uniform some time is required for the release of the actuating lever after it is lifted to stop dog releasing position. In order that the stop, dog may be free to engage after each actuation I provide an escapement mechanism cOmpriSing a pair of escapement dogs 29 and 30, the dog 29 being mounted on the pivot 28 of the release mechanism 27 and the dog 30 on the pivot 26 of the stop dog. These escapement dogs are disposed to coact with pins 31 and 32 on the wheels 33 and 34:, respectively, the pins being arranged so that when the parts are in their initial position the dog 30 is in position to engage the pin 31 and when the stop dog 25 is disengaged the escapement dog 29 is in position to engage the stop pin 32.

The wheels 33 and 34 are, in the structure illustrated, part of a chain of driving gears for the governor 35 which is of the fan type.

The chime movement is mounted in the casing at the side of but independently of the clock movement which permits the structures being manufactured and assembled as independent units, which is of manufacturing advantage in that the clocks maybe sold independently or in connection with the chimes as desired and also a complication of the clock mechanism is avoided.

Various of the parts are shown conventionally, as their structural details form no part of my invention and will, it is believed, b readily understood. 7 I have illustrated and described my imrovements in one form in which I have embodied the same. I have not attempted to illustrate or .describe certain variations in structural details which I contemplate as I believe the disclosure made will enable those skilled in the art to which my invention relates to embody or adapt the same as may be desired.

Having thus described my invention, what I Iclaim as new and desire to secure by, Letters Patent, is:

1. In a structure of the class described, the combination with a clock movement including a driven spindle, a star wheel on said spindle, a trip lever disposed to be actuated by said star wheel, a set of sound members, hammers pivotally supported to coact with said sound members, a hammer actuating drum provided with hammer actuating tappets, a drum driving mechanism comprising a stop disk, a coacting pivoted stop dog, a pivoted, release member for said dog actuated by said trip lever, a pair of escapement dogs one of which is mounted on the stop dog pivot and the other on therelease member pivot, and escapement wheels provided with pins coacting with said escapement dogs.

2. In a structure of the class described, the combination of a set of sound members, hammers pivotally supported to coact with said sound members, a hammer actuating drum comprising a plurality of disks disposed side by side and provided with hammer actuating tappets, said disks being ad justable relative to each other to determine the order of actuating the hammers, a drum driving mechanism comprising a stop disk provided witlrdifferently spaced notches, a coacting stop dog, and a release means therefor.

3. In a structure of the class described, the combination of a set of sound members, hammers pivotally supported to coact With said sound members, a hammer actuating drum comprising a plurality of disks dis posed side by side and provided with hammer actuating tappets, a 'drum driving mechanism comprising a stop disk provided with difi'erently spaced notches, a coacting stop dog, and a release means therefor.

In witness whereof I have hereunto set my hand and seal in the presence of two witnesses JAMES B. PHILLIPS. [L. s]
