May 2, 1933. .1. WALDHEKM I CLOCK SILENCING DEVICE Fil ed Feb. 18, 1927 Patented May 2, 1933 PATENT @FFKIE JOHN WALDHEIM, F ELIZABETH, JERSEY CLOCK SILENGING BEVICE Application filed February 18, 122?. Serial 1%. 169,137.
This invention relates to a clock silencing device.
The ticking of a clock in a bedroom has, in many cases, proved an annoyance to the extent of preventing people from sleeping, and for this reason many persons who would like to have a clock in their bedroom are deprived of the convenience of an alarm clock to awaken them because the ticking sound of the f clock keeps them from falling asleep, and in the absence of an alarm clock they must depend on others for awakening them. The present invention provides means for *ilencing the ticking sound of the clock. To this end there is provided a sound proof casing including an outer shell which may be lined with sound deadening material such as felt. The casing includes a body partwhich encases the clock, and a door which may be pivoted on the body part so that it may be opened in order to put the clock in the case, to give access to the winding handles of the clock, or enable the alarm of the clock to be heard.
A feature of the invention relates to means to automatically release a latch, which normally holds the door shut, so that the door may be automatically opened to let the sound out of the casing so that the alarm may readily be heard when it is sounded in order to awaken the sleeping person.
Another feature relates to means to arrest the door in a partially open position, sufficient to enable the alarm to be heard. The door is arrested in this position to keep it from accidentally striking other objects which may be located near it.
A further feature of the invention relates to means to release the door from its partially opened position, at will, so that it may be completely opened in order to wind the clock or permit its removal.
Other features and advantages will hereinafter appear.
Figure 1 is a front elevation of the casing showing an alarm clock therein.
Figure 2 is a vertical section taken on the line 2-2 of Figure 1.
The casing or cabinet 5 includes a body part 6 and a door 7 both of which may be die cast. The body part and door are pro vided, respectively, with lugs 10 and 11 through which passes a rod 12 to form a hinge 13 for said door.
The body part 6 is provided, at its end' opposite the door 7, with a cylindrical sight opening 1 1- through which the face of an alarm clc 15 n ay be observed. Said sight opening is closed by a circular, glass or other transparent plate 16 which is support 60 ed in the casing by a shouldered ring 17 of sound deadening material, which material mav be of felt, said ring 17 being eifective to keep the plate 16 from touching the body part or shell 6. "i
The shell 6 may be substantially cylindrical and is provided with a lining 18 of sound deadening material. A pad 20 of sound deadening material covers the floor 21 of the body part 6 and the feet 22 of the f t clock rest upon said pad. A flat ring 23 of sound deadening material holds the plate 16 on the shoulder 21 of the ring 17. The ring 24 is wide enough to keep the front of the clock 15 from touching the glass plate 16 so?? as to prevent the sound vibration of the clock from being transmitted to said plate. The lining 18 and the pad 20 abut against the ring 23 to hold it, the glass plate 1.6 and the ring 17 in place, said lining and pad be-: ing secured in position in any convenient manner as for example by glue. The casing is further lined with a flat piece 25 of sound deadening material on the door 7 and which may be secured. thereto in any convenient-$ manner. Strips 26 of sound deadening material may be provided between the ends of the lining 18 and the pad 20.
It will be understood that the ends of the lining 18 form with the pad 20 a clearance-9 cut-out 27 for the feet 22 of the clock. A clearance cut-out 28 is provided in the lining 18, at the top of the casing, for the carrying ring 30 of the clock and the post 31 to which said ring is connected.
It will also be understood that the plate 13 forms with the clock crystal 32, a double closure, at the front of the casing, with an air or sound insulating chamber 32 therebetween.
It will readily be understood that when the door 7 is swung to the position A, in Figure 2, that the clock may be removed from or inserted into the casing or that the clock winding handle 32 and the alarm winding handle 33 may be manipulated. After the clock has been placed into the casing, and against the ring 23, it may be secured in place by a split spring ring 34 which may be contracted by two finger pieces 35 to permit its insertion into the casing, against the back of the clock, and which expands to grip the lining 18, to assist in holding the clock in the case against accidental displacement.
To keep the door 7 closed there is provided a latch element 37 which may be supported on said door. The latch has a portion 37 which engages behind a lug 38 inte ml with the body part 6 of the casing.
e latch element is secured to a stub shaft 40 which serves as a pivot and is supported in a boss 41 on the door 7; said shaft being provided with a finger piece 42 by which the atch element may be operated manually to open the door at will. Said latch element includes an arm 43 which plays between two ins 44 and 45 to limit its motion in either irection.
It is desirable to silence the clock so that the ticking sound thereof cannot be heard as above explained. It is also desirable to hear the alarm 45" of the clock when it is sounded. Accordingly provision is made to automatically open the door 7 when the alarm is sounding. To this end the arm 43 of the latch element is provided with a projection or pin 46 which extends into the path of the alarm winding handle 33. As soon as the alarm starts to sound the handle 33 rotates in a reverse winding direction (clockwise in Figure 1) to engage the pin 46 to swing the latch element 37 about the axis of the shaft 40 to swing the portion clear of the lug 38. The door may then be swung, by gravity, about the axis of the hinge 13, since the center of gravity of the door is to one side of the axis of said hinge, to let the sound of the alarm out of the casing.
To arrest the door in a partially open position and prevent it from striking other objects which may be near it, the latch element is provided with an arm 47 having another engaging portion or stop 48 to engage the lug 38 to arrest the door 7 in position B, Figure 2. The latch arm 43 may be provided with a weight 50 which tends to return the latch to its normal position on the door.
When the door is to be opened to the position A, from the position B, the latch element may be differently actuated by the fingerplece 42 to swing the stop 48 clear of the lug 38. When the door 7 is completely open, as in position A, access may be had to the clock for winding or removal from the casing.
The casing may be provided with a base 51 to which are secured feet 52 of sound deadening material to support the casing.
It will be understood that in order to sto the alarm the door is opened to po ition K so that the alarm stopping lever (not shown) may be reached.
While certain preferred embodiments of this device have been shown and described, it will be understood that changes in the form, arrangements, proportions, sizes and details thereof may be made without departing from the scope of the invention as defined in the appended claims.
