UNTTED TABS SOLON B. BRICKER, OF ST. PARIS, OHIO.

CLOCK.

Application filed October 14, 1911.

To all whom it may concern Be it known that It, SoLoN B. BRICKER, a citizen of the United States, residing at St. Paris, in the county of Champaign and State of Ohio, have invented certain new and useful Improvements in Clocks, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to clocks and has for its object the production of a striking device for the quarter of an hour, which may be connectedto the main striking gear of the clock, thereby doing away with the necessity of providing a separate gear for the quarter strike.

Another object of this invention is the production of a simple and etlicient shifting means for causing the different striking arms to operate.

With these and other objects in view this invention relates to certain novel constructions, combinations, and arrangements of parts as will be hereinafter fully described and claimed.

In the drawings: Figure 1 is a vertical fragmentary section of the striking mechanism. Fig. 2 is a vertical section through the clock frame showing the shifting means for the striking mechanism. Fig. 3 is a vertical section through the clock casing showing the operating mechanism for the striking device. Fig. 4: is a transverse section through the frame showing the striking mechanism operating device in bottom plan. Fig. 5 is a transverse section taken through the casing showing the shifting mechanism in top plan. Fig. 6 is a transverse section taken through the casing showing the arrangement of the control arms for the striking mechanism in top plan. Fig. 7 is a fragmentary vertical section taken through the back plate of the casing showing an end View of the releasing lever and wheel. Fig. 8 is a side view of the locking disk for the striking device. Fig. 9 is a perspective of the releasing lever of the striking device. Fig. 10 is a vertical section through the clock frame showing the releasing lever and wheel in side elevation. Fig. 11 is a fragmentary view of the casing showing the support for the clapper arms. Fig. 12 is a detail perspective of the control arms and support therefor. Fig. 13 is a perspective view of the shaft carrying the counting control arm.

Specification of Letters Patent.

Patented June 1, 1912.. Serial No. 654,686.

Referring to the drawings by numerals 1 designates the back plate of the frame which supports the front plate 2 in the unsual manner by spacing bars. The main shaft 3 passes through the plates 1 and 2 and carries near its end a cam-star wheel 1 upon which rests the curved end 5 of the arm 6 carr 1ed by the releasing lever 7. The re leasing lever 7 is pivotally secured to the back plate 1 as at 8 and is provided with a notch upon its upper edge which is adapted to be engaged by the angle end of the rais- 1ng arm 9 carrled by the control shaft 10.

A stop arm 11 is carried by the shaft 10 and is provided with a downwardly extendlng end adapted to engage one of the laterally extending lugs 12 carried by the checklng gear 13. A stop arm 1 1 is also carried by the control shaft 10 and is provided with a laterally extending end being adapted to en age notches 15 formed in the check disk 16. The arm 17 which controls the number of strikes by each clapper is also carried bv the controller shaft 10. This arm 17 is bent intermediate its end as at 18 so as to accommodate itself to the gearing carried by the frame. The end of the arm 17 is flattened and bent downwardly for forming a tooth gripping blade as at 19 for engaging the teeth of the counting wheel 20 hereinafter described. A shaft 21 is carried near the upper end of the frame upon which is mounted the check gear 13. A small gear 22 is secured to the gear 13 and meshes with a gear 23 carried by the shaft 29. A sleeve 25 is carried by the shaft 21 and one end of the shifting bracket 26 is secured thereto. The sleeve 25 is cut away at 27 to allow the gear 28 to rotate.

The strike operating shaft 29 is carried by the frame between the controller shaft 10 and the shaft 21. This shaft 29 carries the gear 23 hereinbefore mentioned, to which gear is secured the stop disk 16. The strike operating cam 30 is carried by a sleeve 31 which works upon the shaft 29. A pin 32 is carried by the shaft 29 and works in the slot 33 formed in the sleeve 31 so as to allow longitudinal movement of the sleeve but prevents the rotary movement thereof relative to the shaft 29. The striking cam 30 comprises a pair of fingers 34 which are curved upon their back to allow the clapper arms 35 to be easily operated. One end of the shifting bracket 26 is carried by the shaft 29 and a collar 36 is placed upon the collar 31 to hold the same in engagement with one end of the shifting bracket 26. A lug 37 is carried by one side of the shifting bracket 26 and is provided with a projecting finger 38 which finger is adapted to be engaged by the shifting arm 39 of the shifting mechanism. A gear 40 is carried by the shaft 29 and meshes with the gear 28 car ried by the shaft 28 for imparting rotary movement to the counting gear 20 through the medium of the gear 42. A gear 43 is keyed to the gear 28 for engaging the regular clock gearing.

A cam wheel 44 is carried by the main shaft 3 and comprises a pair of spaced disks between which fits the depending end of the shifting arm 45. The

arms

39 and 45 are carried by a shaft 46 which is supported upon a bracket 47, which bracket is sup ported by the front plate 2. A number of

gears

48, 49, and 50 are carried by the shaft 3 for connecting with the diiferent gears for operating the hour, minute and date hand of the clock in the usual manner.

A spacing member 51 is positioned between the back plate 1 and the front plate 2 and carries a hanger bracket 52 intermediate its ends. A clapper supporting shaft 53 is supported upon each side of the hanger bracket 52 and each of the shafts 53 has a coil spring wound around the same for nor mally holding the striking end 54 in engagement with the bell or signal. A finger 55 is carried by each shaft and is provided with an angle end fitting in the stop notch 56 formed in the plates 1 and 2 The upper ends of the clapper arms 35 are bent so as to face each other and are adapted to be engaged by the cammember 30 as hereinafter described.

From the foregoing description it will be obvious that as the main shaft 3 is rotated every one fourth of a turn the releasing lever 7 will be raised thereby raising the arm 9 and rotating the shaft 10, whereby all the arms carried by the shaft 10 will be raised and allowing the counting wheel to rotate and cause the clapper which is adapted to indicate the quarter of an hour to operate. This clapper just mentioned will be operated by the cam 30 as the same rotates, the rotary movement being imparted thereto by the

gears

20, 42, 28 and 40. The arms which are carried by the shaft 10 are held in their normal position by means of the spring 57 which bears upon the arm 11. As the shaft is operated one whole revolution the curved portion 58 engages the depending end of the arm 45 thereby swinging the same and causing the shifting bracket 26 to slide upon the shaft 29 so as to have the cam 30 engage the clapper which engages the hour signal and operate the same. As the shaft 3 continues to rotate the cam 30 will be again brought back to its normal position. The number of strikes is regulated by the counting wheel 20 which is engaged by the flattened end. 19 of the arm 17. This wheel 20 is provided with teeth formed upon the edge thereof in the following manner: one deep tooth indicating the end of an hour, one deep tooth indicating the first quarter of the hour, one shallow tooth and one deep tooth indicating a second quarter of the hour, two shallow teeth and one deep tooth indicating the third quarter of the hour and finally the number of teeth to indicate the succeeding hour. This is repeated around the entire wheel, the arrangement between each hour being the same as that just stated.
