FIECHTER Mg@ @9% HIS AT TORN EYS United States Patent O 3,129,557 SETTING MEANS FOR WATERTHGHT CLGCK Rene A. Fiechter, 137 Hollywood Ave., Douglaston, N.Y. Filed ct. 18, 1960, Ser. No. 63,312 5 Claims. (Cl. S15-85.5)
The present invention relates to clocks and more specifically to new and improved clock apparatus that is of particular utility in applications where unfavorable ambient conditions obtain as on shipboard, for example, although it is not limited to such use.
It has been difcult heretofore to keep clocks in good operating condition for extended periods under the generally adverse conditions prevailing on shipboard. The humidity is usually very high and in the case of ocean going vessels the atmosphere frequently contains line droplets of salt water. These conditions tend to cause rapid oxidation of metal clock parts and of the lubricants commonly employed to reduce friction in the clock mechanism. Clocks incorporating electrical components such as switch contacts and transistors, for example, are also adversely .affected by these unfavorable factors. As a result, the timekeeping qualities of clocks used on shipboard tend to be soon impaired and frequent failures occur. This presents difficult and expensive problems of maintenance on a large vessel where a considerable number of clocks are used.
It is an object of the invention to provide new and improved clock apparatus which is fully protected against adverse ambient conditions such as high humidity and salt water droplets.
Another object of the invention is to provide new and improved clock apparatus of the above character incorporating novel time setting mechanism.
These and other objects of the invention are attained by mounting the clock mechanism in a sealed envelope which is either evacuated or contains an inert gas. In this fashion, the delicate clock mechanism is made completely inaccessible to unfavorable ambient conditions that might tend to damage it or impair its timekeeping qualities. The invention also contemplates the provision of means for changing the time setting of the clock mechanism without removing it from the sealed envelope in which it is contained.
For a better understanding of the invention, reference is made to the following detailed description of several representative embodiments thereof, taken in conjunction with the accompanying drawings, in which:
FIG. l is a view in longitudinal section of clock apparatus constructed according to the invention; and
FIG. 2 is also a view in longitudinal section of a modied clock apparatus embodying a different form of time setting mechanism from that shown in FIG. l.
While the invention may be effectively utilized in conjunction with any form of clock movement whatsoever, it will be described herein, for purposes of illustration, as applied to a conventional electric (transistor or switch contact) clock movement.
In the form of the invention shown in FIG. l, a .con ventional electric clock movement with the usual dial 11, and minute and hour hands 12 and 13, respectively, is mounted within a sealed envelope 14. The envelope 14 comprises a rear plate 15 having a central cylindrical well 16 formed therein to receive the clock movement 10 lCe and a front cover member 17 cemented or otherwise secured to the outer edge of the plate 15 so as to form an airtight joint. The cover member 17 should be made of a transparent material such as glass and the rear plate 15 may also be made of glass, although other suitable materials can be used. Leads 18 and 19 for supplying electrical energy to the clock mechanism 10 extend from the latter to sockets 20 and 21 sealed in the rear plate 15 and accessible from outside the envelope 14. Also sealed in the rear plate member 15 is a short tube 22 of glass or other suitable material through which the envelope 14 may be evacuated and then sealed. If desired, an inert gas such as nitrogen may be introduced into the envelope 14 after the latter has been evacuated and before the tube 22 is sealed.
The sealed envelope 14 is mounted llush against a body member 23 having a central recess 24 formed therein to receive the central cylindrical well portion 16 of the rear plate 15. A bezel member Z5 retains the envelope 14 and the body member 23 releasably in assembled relationship. Preferably, suitable annular gaskets 26, 27 and 28 made of ilexible material such as rubber, for example, are interposed between the envelope 14 and the body member 23, as shown in FIG. 1. Also, a gasket 29 is preferably interposed between the outer lip 30 of the bezel member 25 and the envelope 14.
The body member 23 is hingedly mounted at 31 to a backing plate 32 which may be secured in any suitable manner to a wall or other support. Formed in the backing plate 32 is a recess 34 which cooperates with recesses 35 and 36 formed in the body member 23 to constitute a battery chamber 37 and a passage for leads therefrom to the sockets 2l) and 21 in the rear plate 15 behind the clock mechanism 10. A conventional dry cell battery 38 is mounted in the chamber 37 between spring contact brackets 39 secured to the body member 23. Leads 40 and 41 connect plugs 20a and 21a inserted in the sockets 20 and 21, respectively, to the two battery terminals as shown in the ligure.
It will be understood that the battery 38 can easily be removed and replaced simply by pivoting the body member 23 about the hinge 31 to provide access to the battery chamber 37.
In accordance with the invention, the clock mechanism 10 is adapted to be set to the correct time by magnetic means external to the envelope 14. In one embodiment, this may be a simple bar magnet 42 which is positioned with one pole against the outer face of the envelope 14 adjacent the minute hand 12. The latter should be made of magnetic material such as soft iron, for example, so as to be attracted to the magnet 42. Also, provision should be made, as by bending the tip 43 of the minute hand 12 forwardly towards the cover member 17 of the envelope 14, to insure that the minute hand 12 will not come into engagement with the hour hand 13 while the clock mechanism 1t) is being set. By moving magnet 42 in a circular path in contact wih the outer face of the envelope 14, the minute hand 12 can be rotated to any desired setting. If desired, an annular groove 42a may be formed in the outer face of the envelope 14 to serve as a guide for the magnet 42, but this is not necessary.
FIG. 2 illustrates another form of magnetic means for setting the clock mechanism 10 from outside the envelope 14 according to the invention. In this embodiment, the minute hand 12 extends almost to the inner side wall of the envelope 14 and it terminates in a pole piece 44 of magnetic material such as soft iron. The minute hand 12 is adapted to be moved by a permanent magnet 45 which normally is kept away from the pole piece 44 but can be moved into close proximity thereto when the clock setting is to be changed. To this end, the magnet 45 is carried by a ring gear 46 disposed in an annular groove 47 formed in the body member. Resilient means such as the springs 48 normally urge the ring gear rearwardly so that the magnet is kept away from the pole piece 44 on the minute hand.
The ring gear 46 is adapted to be rotated about the body portion 23 by a pinion 49 carried by a shaft 50 which can be turned by a knob 51 located at the front of the clock apparatus. The shaft 50 is also mechanically connected to the ring gear 46 by any suitable coupling 52 permitting rotation of the shaft 50, so that when the knob 51 is pulled away from the clock and turned, the magnet 45 can be brought into proximity with the pole piece 44 on the minute hand 12, which they will follow the magnet 45. One advantage of this structure is that the magnet exerts only a radial force on the minute f hand 12 so that there is no likelihood of the minute hand 12 coming into engagement with the hour hand 13.
In order to protect the clock movement 10 from the effects of the magnetic field, a magnetic shield 53 of suitable material such as soft iron may be interposed between the dial 11 and the clock movement 10. Alternatively, the dial 11 may be made of suitable magnetic material so as to serve as a magnetic shield.
It will be apparent that the novel clock structure of the invention enables maintenance procedures to be greatly simpliiied. In the irst place, by mounting the clock movement in a sealed envelope which protects it from adverse ambient conditions, the number and frequency of clock failures is much reduced. Secondly, when failures do occur, it is a very simple matter to remove the defective clock movement in its sealed envelope and to replace it with another in good working order. This requires only that the body member 23 be swung upwardly about its hinge 31 to permit the plugs 20a and 21a to be removed from the sockets 20 and 21 and that the bezel member 25 be detached so that the envelope 14 containing the clock movement 10 can be removed and replaced by another. An adequate supply of replacement clock movements in sealed envelopes can be kept for long periods of time even in ships stores on shipboard and still remain in perfect condition,
If the defective clock movement is an inexpensive one, so that repairs would not be worth while, it can be thrown away in its sealed envelope. On the other hand, if an expensive movement is used, the defective unit can be returned to a repair facility for removal from its sealed envelope and repair, following which it can again be mounted in a sealed envelope and returned to stock.
The invention thus provides novel clock apparatus that is of particular utility under adverse ambient conditions, such as those that prevail on shipboard. By mounting the clock movement in a sealed envelope that is either evacuated or contains an inert gas, it can be effectively protected from humidity or salt in the air. Moreover, the invention provides highly eifective'magnetic means for setting the time of the clock movement from the outside of the envelope in which the movement is contained.
The several specific embodiments are only typical and many variations in form and detail are possible within the scope of the invention. For example, the envelope may be made of materials other than glass, provided only that it is impermeable to air and humidity and permits the hands to be viewed therethrough. A rechargeable battery may be used in place .of the dry cell 38. Also, while the several clocks shown are intended to be mounted on a wall or the like, the invention can be embodied in other forms of clocks as desk clocks, mantel clocks and the like, and shapes other than circular may be used. Other modifications will be apparent to those skilled in the art.
The invention, therefore, is not to be limited to the specific devices described herein but is intended to encompass all modications thereof falling within the scope of the following claims.
