Patented Aug. 16, 1938 2,126,906 UNITED STATES PATENT OFFICE 2,126,906 CLOCK Herschel McCurdy, Detroit, Mich. Application April 1, 1937, Serial 134,398 2 Claims. My invention relates to a new and useful im provement in an insulated escapement for use on clocks and the like. It is an object of the present invention to provide a clock with an escapement enclosed in a sound-proof housing so that the ticking which is ordinarily heard to proceed from a clock will be silenced and a silent operation of the clock made possible. 10 Another object of the invention is thepro vision of a device of this class which will be simple in structure, economical of manufacture, durable, compact and easily and quickly in ’ stalled. 15 Other objects will appear hereinafter. The invention consists in the combination and arrangement of parts hereinafter described and claimed. The invention will be best understood by a ref 20 erence to the accompanying drawing which forms a part of this speci?cation and in which, Fig. 1 is a side elevational view of a clock with a part broken away and embodying the invention which is shown in section. 25 Fig. 2 is a sectional View taken on line 2—2 of Fig. 1. Fig. 3 is a fragmentary sectional view taken on line 3—-3 of Fig. 2. Fig. 4 is a view similar to Fig. 1 showing a 30 slightly modi?ed form of the invention. As shown in the drawing, the shaft 8 on which the escapement wheel 9 is ?xedly mounted is extended and the escapement wheel is enclosed in a sound-proof housing If]. The shaft H on 35 which the detent yoke I2 is ?xedly mounted is also enclosed in the housing Ill so that the entire equipment is enclosed in the sound-proof enclosure. In this way the ticking sound is en tirely eliminated in a clock of this type. It will 4.0 be noted that the housing I0 is mounted on the upper wall 3 of the clock works frame all of which are enclosed in the casing Hi. In Fig. 4 I have elevated the frame to pro vide a yoke 15 in which the end of the shaft 8 45 is projected to form a bearing therefor. The end of the shaft II is also extended into the elevated portion I5 to provide a bearing, and the sound proof housing It’ is mounted so as to embrace the escapement movement. In this way I have provided a clock action 50 which is of the usual spring operated type and in which there has been a silencing of the ticking (CI. 58-53) ' sound which usually emanates from clocks of this type. v While I have illustrated and described the pre ferred form of construction, I do not Wish to limit myself to the precise details of structure shown but desire to avail myself of such vari ations and modi?cations as may come within the scope of the appended claims. Having thus described my invention, what I claim as new and desire to secure by Letters Pat 10 ent is: 1. In a timepiece of the class described, a sup porting frame embodying a. pair of oppositely disposed plates; means for securing said plates together in spaced relation; a clock mechanism 15 mounted on said frame between said plates; a sound-proof housing positioned on said frame with one of the sides of said housing engaging the outer face of one of said plates; means for securing said housing in ?xed relation to said 20 plates; a pair of shafts journalled in said frame and projecting through the plate engaged by said housing and extending into said housing; an escapement wheel ?xedly mounted on one of said shafts in said housing; a pinion mounted on 25 said last-named shaft between said plates and cooperating with said clock mechanism for rotat ing said last-named shaft; and a detent mount ed on the other of said shafts within said hous ing for cooperating with said escapement wheel. 30 2. In a timepiece of the class described, a sup porting frame embodying a pair of oppositely disposed plates; a clock mechanism mounted on said frame between said plates; a sound-proof housing positioned on saidv frame with one of 35 the sides of said housing engaging the outer face of one of said plates; means projecting through said plates and through said housing for securing said plates together and securing said housing thereon in fixed relation thereto; 40 a pair of shafts journalled in said frame and pro jecting through the plate engaged by said hous ing and extending into and terminating in said housing; an escapement wheel ?xedly mounted on one of said shafts in said housing; a pinion 45 mounted on said last-named shaft between said plates and cooperating with said clock mecha nism for rotating said last-named shaft; and a detent mounted on the other of said shafts with in said housing for cooperating With said escape- 50 ment wheel.
