FREDERICK WEHINGER, OF WATERBURY, CONNECTICUT, ASSIGNOR TO WATERBURY CLOCK CO., OF WATERBURY, CONNECTICUT, A CORPORATION.

CI-IIME-CLOCK.

Application filed February 21, 1918.

To all whom it may concern:

Be it known that I, FREDERICK WEHINGER, a citizen of the United States, residing at Waterbury, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Chime- Clocks; and I do hereby declare the following, when taken in connection with the accompanying drawings and the characters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this application, and represent, in

Figure 1 a view in left hand edge elevation of a chime-clock constructed in accord ance with my invention.

Fig. 2 a view thereof in front elevation.

.Fig. 3 a view thereof in vertical section on the line 3-3 of Fig. 1 looking from front to rear.

Fig. 4 a similar view showing the chimetrain after it has been warned and prior to its release, and the chime cut-out lever in its operative position in which it cuts out the chiming hammers.

Fig. 5 a detached perspective view in rear elevation of the four-point warning and releasing chime-cam, showing its turn-back bevels.

Fig. 6 a detached perspective view of the lifting lever, which co-acts with the said cam.

Fig. 7 a perspective view of the chime cut-out lever.

My invention relates to an improved chime-clock, the object being to reduce the width of the movement. so as to permit it to be introduced into a relatively small case, to make its parts accessible for adjustment and repair, and to reduce the cost of its production.

With these ends in view, my invention consists in a chime-clock characterized by havingfront, rear and intermediate movement-plates spaced apart to form front and rear train-spaces, and by having a timetrain and a strike-train located in such front train-space, and a chime-train in such rear train-space.

My invention further consists in a chimeclock in which the time, chime and striketrains are so interrelated that the chimetrain will be warned and released by the time-train, and so that the strike-train will Specification of Letters Patent.

be warned by the time-train after the chimetrain has been warned, and released by the chimetrain after the chime has been rung.

My invention further consists in certain details of construction and combinations of parts as will be hereinafter described and pointed out in the claims.

In carrying out my invention as herein shown, I employ a front movement-plate, intermediate movement-plate 5, and a rear movement-plate 6,. the said plates being spaced apart by pillars 7 to produce a front train-space 8 and a rear train-space 9. In the front train-space 8, I locate the timeand strike-trains which may be of any approved construction, and in the rear trainspace 9, the chime-train, also of any approved construction, and provided with a chime-drum 10 mounted on an arbor 11 j ournaled in the said plates 5 and 6 and set with chime-pins 12 co-acting with hammeroperating fingers 13 extending inwardly from hammer-hubs 14 provided with hammer-wires 15 carrying hammers 16. The said hubs 14 are mounted upon an arbor 17 supported at its ends in the plates 5 and G, and also mounting at its forward end a hub 18 provided with a hammer-wire 19 carrying a strikehammer 20 which is operated independently of the chime-drum 10 as will be hereinafter described.

It will be seen from the foregoing that I locate in the rear train-space 9 of my improved clock, not only the chime-train, but also the entire battery of chime-hammers 16 as well as the chime-hammer 20 and the various parts required for the mounting and operation thereof, whereby I am enabled to reduce the width of the movement without substantially increasing it in thickness from front to rear over an ordinary chime-clock in which the time, strike and chime-trains are arranged side by side in line between the front and back movement-plates and in which the hammer battery and the parts for mounting and operating the same are located entirely back of the back movementplate in an exposed and unprotected position where they virtually increase the thickness of the movement. I am thus enabled to reduce the width of the movement without substantially increasing it in thickness over clocks of the prior art in which an exposed ha-mmer-battery located back of the back movement-plate virtually doubles the depth ofthe movement so far as the problem of casing is concerned.

' Thecenter arbor 21 which is journaled in the

plates

4 and 5, mounts a warning and chime-train. (I may here say that I use the term lock-work in the sense in which it is generally used by clock-makers to ties--v ignate the arbors, wires and co-acting parts employed to control the stopping and releasing clocks.)

The arbor 28 mounts a lifting-hook 29 extending under a chime count-hook 30 of the strike-and chime-trains of mounted in a chimelocking arbor 31 jour-. naled in the plates 5 and 6 at a point substantially above the arbor 28. The said hook 30 co-acts with a chime count-Wheel- 32 mounted upon the third: wheel arbor 33 of the chime-train, the said arbor being journaled inthe plates 5 and 6' and carrying the third. wheel 34 which. meshes'into a wheel 35 on the arbor 11 and so drives the,

chime-drum 10. Atits rear end the arbor 33 mounts pinion- 36 meshed'into by the second Wheel 37 of the chimetrain, the said wheel being mounted upon the second arbor 38 of the-said train, and the sald arborhaving a pinion 39 meshed into by the maln:

wheel 40 mounted upon the chime-winding arbor 41, also mounting the cl'iinie-spring 42.

The third wheel 34 of thefchime-train meshes into a pinion 43 on the arbor 44 of the fourth wheel 45' which meshes into a pinion 46 on the arbor 47' of the fifth wheel 48 which meshes into a pinion 49 on the arbor 50 mounting a fly 51, all of'the partsi last mentioned belongingto the chime-train. The fourth wheel 45 carries a locking-pin 52 co-acti'ng with the hooked end of a locking-wire 53 mounted in the chime-locking arbor 31 and and raising alifting-hool': 54' mounted in a strike-warning arbor 55' journaled between the plates 5 and 6and mount ing at its forward end a strike-warningwire 5'6'wh1ch reaches forwardthrough the intermediate movement-plate 5 and coacts with a locking-pin 57' in the fourth wheel: 58 of the strike-train which is located in;

the front train-space 8. The fifth wheel 48 of the chime-train carries a chime-warning pin 59 co-acti'ng' with the bent end of a chime-warning wire 60 which is mounted in the chime-warning arbor 28.

The center arbor 21 also mounts a onepointfstrike cam 61 locatedin thev front train-space 8 at a point in front of the chime-cam 22 and operatingonce an hour upon the bent lower end of a strike liftingwire 62 depending from an arbor 63 jour-" naled between the

plates

4 and 5 and pro vided at its forward end with a hook 64 which, operates to lift a strike count-hook 65 mounted in the forward end of a counthook arbor 66 journaled between the

plates

4 and 5, the flattened outer end of 67 of the count-hook co-acting with an ordinary strike count-wheel 68 concentric with the strike-winding arbor 69.

The count-hook arbor 66 mounts the strike locking-hook 70' the bent outer end; of which co-acts with the strike lockingpin 57 aforesaid. The said arbor 66 also mounts a cam-hook 71'which co-acts With a cam 72 mounted upon the arbor 73 of the third wheel 74' of the strike-train, the function of the hook 711 and cam 72 being to lift'the flattened end 67 of the strike counthook 65 clear of the teeth of the strike count-wheel 68 in the usual manner. A tripping wire 75 depending from the hook 64'provides for manually starting the striketrain' so as to synchronize it with the timetrain when required.

The strike third wheel arbor 73 projects at its rear end through the intermediate plate-5 and is provided with a hub 76 carry ing two strike-pins 77 which engage with the hooked outer end of the strike hammertail' 78 mounted in the strike-hammer hub 18 aforesaid, whereby the strike-hammer 20 is operated when the strike-train is released, for striking the hour, 6

The stri ke-train is driven by a strike ma'in spring 79 located in the space 8, mounted uponthe strike winding-arbor 69 and driving the main wheel 80 of the strike-train, the said wheel 80 meshing into a lantern pinion 81 on the arbor 82 of the second wheel 83 of the strike-train. The said arbor 82 is furnished at its forward end with a pinion 84 which meshes into, and. drives the count-wheel 68. The said second wheel 83 meshes into a pinion 85 on the third wheel arbor 73 carrying the third wheel 74 which meshesinto a pinion 86 upon the, arbor 87 of the fourth wheel 58 of the strike 7 train, the said wheel 58 meshing into a lantern pinion 88 upon the arbor 89 carrying the fly 90. The parts last described form the strike-train and are located within the front train-space 8.

The time-train, also located within the front train-space 8, V consists as. herein Sl10W11,,0f21- main wheel 91 driven by a time spring 92 on the time winding-arbor 93 journaled in the

plates

4 and 5. The wheel 91 meshes into a pinion 94 on the arbor 95 of the second wheel 96 which meshes into a pinion, 97 on the arbor 98 of the third wheel 99 which meshes into a pinionlOO on the ar-.

bor 101 of the fourth wheel- 102 which.

meshes into a pinion 103 on the arbor 104 of an escapement-wheel 105 co-acting with a verge 106 on the verge arbor 107. The secondwheel 96 of the t-imetrain meshes into a center wheel 108 on the center arbor 21 and drives the same. The arbor 21 is pro vided with a cannon pinion 109 meshing into a minute-wheel 110 mounted on an arbor 111 carrying a pinion 112 which meshes into an hour-wheel 113 carrying an hoursocket 114:, this dial-Work, so called, being located directly back of the front movementplate 4.

To enable the user of the clock to cut out, and so silence the chime at any time, I employ an arbor 115 mounted in the plates 5 and 6 and designed to project through the dial (not shown) for the application of a key to its squared forward end. bor is provided at its rear end with a hub 116 located within the rear train-space 9 and furnished with an operating and locking pin 117 co-acting with an inclined operating face 118 upon the upper end of a locking cut out lever 119 also furnished at its upper end with an overhanging hook 120- having a. locking stop-notch 121. The said lever is hung upon a stud 122 and formed at its lower end with a rearwardly turned arm 123, the upper edge of which normally stands adjacent to the inner ends of the hammer-wires 15 of the chime-hammers 16, the arm being cut away as at 124: to clear the strike hammer-wire 19 so as to prevent the same from being effected by the operation of the lever 119.

It will be seen from the foregoing de scription that although the strike and chime trains are located on opposite sides of the intermediate movement-plate 5, their lockwork is intenrelated so that the chime-train may be utilized for controlling the release of the strike-train, although the same is warned in the usual manner by the timetrain whereby the operation of the striketrain is brought into proper sequence with the operation of the chime-train, and also whereby the chime-train is relieved of the burden of warning the strike-train which my invention devolves upon the time-train.

For the purpOse of describing the operation of my improved chime-clock, it may be assumed that one of the points 23 of the four-point chime-cam 22 has lifted the lifting lever 27 whereby the chime-warning arbor 28 is rocked and the chime-warning wire 60 lifted into the path of the chime-war ingpin 59 in the fifth wheel 48 of the chimetrain. At the same time, the lifting-hook 29 acts to lift the chime count-hook 30 out of one of the notches in the chime count-wheel 32. Through the lifting of the count-hook 30. the chime-locking arbor 31 is rocked to lift the hook 53 out of the path of the locking-pin 5-2 in the fourth wheel 45 of the This archime-train. Then the locking-pin 52 is released, the chime-train is driven by its spring 42 until the warning-pin 59 is engaged with the upturned end of the chimewarning wire 60, as shown in Fig. 4:. The chime-train is now warned. The action just described, takes place innnediately previous to every quarter hour, and every time it takes place the rocking of the arbor 31 acts through the chime-locking wire 53 to raise the lifting-hook 5 1 and so rock the strike warning-arbor 55 carrying the strike warning-wire 56 which is lifted into the path of the strike locking-pin 57 in the fourth wheel 58 of the strike-train. However, such periodic lifting of the hook is without effect except on the hour or in other words, at the conclusion of the fourth quarter, when directly after the warning of the chime-train as described, the single point strike-cam 61 will operate through the strike lifting-wire 62 to unlock the strike-train which will now start and run until its pin 57 has been brought into engagement with the bent end of the strike warning-wire 56 which has been brought into its path by the rocking of the strike-warning-arbor 55 by the action of the chime lockwork as previously described. The strike-train having thus been warned by the action of the time-train, is now held in readiness to be released by the action of the chime-train after the conclusion of the chiming operation.

The chime-train having thus been warned as described, at the conclusion of the quarter, whatever quarter it may be, the lifting-lever 27 will drop off the particular point 23 now in play of the chime-cam 22. The lever 27 will now fall and permit the chime warningwire 60 to drop downward out of the path of the warning-pin 59 and thus permit the chime-train to run through its chiming phase and ring the chimes. During this time, the chime locking-wire 53 will be held in its elevated position in which it clears the lockingpin 52, by the riding of the chime count-hook 30 upon the periphery of the chime countwheel 32, whereby the locking-hook 53 is prevented from co-acting with the lockingpin 52 until the count-hook 30 has been given the opportunity of dropping into the succeeding notch of the count-wheel 32 which takes place at the conclusion of the chiming phase. When the count-hook 30 drops into the notch as described, it permits the strike warning-arbor 55 to rock, and hence the strike warning-wire 56 to drop down out of the path of the strike locking-pin 57 in the fourth wheel 58 of the strike-train. Now if the strike-train has been previously warned by the time-train, which will be the case if the chimes were last rung on the hour, it will be released by the chime-train for striking the hour, which will be done in the usual manner under the control of the count wheel of the strike-train. It will thus be seen that under my invention, the strike-train after having been warned by the time-train after the warning of the chime-train by the timetrain, is released by the action of the chimetrain when the same has completed the ringing of the chimes. The mechanism employed to release the striketrain by the chime-train operates every quarter, but is only efiective when the operation of' the time-train has previously effected the warning of the strike train, which is done only on the hour.

In setting the clock, it is often desirable to turn the hands counter clockwise. This is provided for without deranging the mechanism, by forming the-points 23 of the cam 22 with turn-back bevels 24 which act upon the hook 25 of the lever 27 to spring the same laterally, permitting the points .23 to ride past it, without deranging the mechanism.

To silence the chimes, it is only necessary to apply a key to the projecting squared forward end of the cut-0ut shaft 115 and turn the same counter-clockwise, whereby the operating and locking pin 117 acting upon the face 118 of the cut-out lever 119 rocks the same on. its stud 122 and causes its bent lower end to rock the hammer-hubs 14 so as to clear their fingers 13 from the action ofthe chime-pins 12, as shown in Fig. 4, the lever 117 being locked in this position by the entrance of the pin 117 into the bottom of the notch 121 formed by the overhanging hook 1-20. On the other hand, by applying the key to the shaft 115and turning the same. clockwise, the lever is allowed to drop into its retired position in which the chimes are per mitted to sound and in which the leveris locked by the entrance of the pin 117 into the locking notch 125 in the edge of the hool 1200f the lever as shown in Fig. 3.

As shown, the hammers are arrangedto ring chimes located in the bottom. of the clock-case. They may, however, be constructed and arrangedato ring chimesloc'ated upon either side of the case or within the top thereof, these being details not connectedwith my present invention. 7
