To all whom it may concern:
Be it known that I, CHARLES L. DEroL- Linn, a citizen of the United States, residing in the borough lof Brooklyn of the city of New York, in the State of New York, have invented certain new and useful Improvements in Watches, of which the following is a specification, reference being had to the accompanying drawing, lforming a. part hereof. Y
The effect upon watches of sudden changes of temperaturev has long been understood. The burden of takingprecautions to prevent such changes of temperature is thrown upon the user. In the recent and greatly extended use of wrist watches, particularly among military men, it has been found that the deficiencies of such `watches as reliable time-keepers are due in large measure to the fact that by reason of the immediate contact with the flesh of the wearer they are subjected constantly to a temperature which, although not excessive, is` considerably higher than the normal atmospheric temperature. Apparently the bad effect of this constant temperature above the normal is due directly to the effect of such continued high temperature uponthe lubricant, which after a considerable period of time is found to have disappeared or to have been chan in quality to such'an extent that the tlme keeping qualities of the watch are reduced. The object of this invention is to provide practical and eflicient means for protecting a watch, particularly a wrist watch, from the effect of long continued heating above the normal by reason of the immediate contact with the flesh of the wearer. Practical considerations of use make it impossible to resort to expedients which would otherwise suggest themselves, that is to say, the watch must not be unduly thick and it must not have within the case any material whichk might, in the course of time, release dust to enter the movement of the watch. On the other hand, the most effective heat insulating materials are for the most part of such character that they will absorb moisture or grease or will wear rapidly if in contact with the flesh of the wearer. The object of this invention, therefore, is to provide eicient means for insulating a watch, particularly a wrist watch, from the heating action to which it would otherwise be subjected by reason of contact with the wrist or bod of the wearer, and shall meet the practica requirements of use as above suggested. In
accordance with the invention the provision for heat insulation is external to the watchcase which incloses the movement and provision is also made for the protection of the heat insulation.
The invention will be more fully explained hereinafter with reference to the accompanying drawing in which it is illustrated as embodied in several possible constructions, and in whichigure 1 is a .view in rear elevation of a watch yto which the invention is applied.
Figs. 2, 3, 4, 5, 6 and 7 are detail views in section, on the plane indicated by the broken line 2 2 of'Fig. l, showing different embodiments of the invention.
bviously theheat insulating means may be applied both to the front and back of a watch, but for ordinary purposes, particularly in a wrist watch, it is suflicient that the insulation be applied to the back of the watch, as indicated in the several figures of the drawing. Itis suiiicient, therefore, to represent in the drawing the back member of the watch as having the insulating means embodied therewith. In the application of the invention illustrated in Fig. 2, the back member a of the case is shown as recessed on its rear or outer face, as at a', to receive a. sheet b of suitable insulating material, such as asbestos. The material named and found generally desirable as a heat insulating material would not wear well if subjected to friction and would absorb dampness and grease. It is therefore necessary to protect externally the insulating means and for this purpose there is provided a cap c which extends nearly over the entire surface of the insulating material, but is not allowed to come directly in contact with the rim a of the case member, in order that the transmission of heat to the watchcase from the cap by conduction may be avoided. The cap therefore is extended not quite to the rim but far enough to protect the insulating material from wear, a narrow, annular space between the watch and the cap and the rim of the case being left, as at a. For securing the cap in position, pins may be employed as they are commonly employed in securing a watch dial in position. The conduction of heat from the cap to the case through such pins is negligible.
If desiredv provisionmight be made for insulation by a dead air space as well as by such insulatingv material as asbestos. I In Fig. 3, the cap 0 has at its periphery a lip or ange c2 Which raises theV cap suttcie'ntlyf to form under it a dead air space. As shown mainly to prevent direct contact, at its edge7 of the. cap c' With the case memberra.
Y In Fig. 15, the rim at of the case member is shownv as adapted, like the bezel of a Watch# case, to receive a metal disk orplate a5 which; has secured to it by. pins c. the asbestos-in-U sulation Z) and the protectingcapfc, sub-' stantially as shown in Fig. 22 the metaldisk a5v 'being held in placein the rim by pressing the metal o-the'rim down upon the edge of 'l i the case member external to the heat insulatthe plate. In Fig. substantially .as in Fig'. 2, with the insulating material applied thereto substantially asin Fig. 2 but with the protecting cap 'c2 held in place,V with the insulating 'materia'l.'V by having the edge of the recess in the-case member rolled down upon itfas shown at a7. VThis arrangement,v hovvever, 1sV less desirable :because jofuthe contact of metal to metal between the cap and the case member."l
"InF-iglV 7 is illustrated an arrangement similarto that shovvnin 5', in which the? `Genies.fiitlisimtenfc may be .obtained for 6, the case member anj is shown December, A.D. 1918.
metall plate Aordisk a5 is :secured in the rim a4, but in this case the insulating material Vb is carried around the edge of the protecting plate c3, as shown at as and the edge 0f the rim a4 is rolled down to hold the insulation and the cap in place.
Various 'other embodiments ofthe invention will suggest themselves.
I claim as my invention: Y l. In a Watch case,y the combination of a case member and a protecting plate secured to thecase member and heatV insulation in-y Y Y terposed between the case member and the 2.V In a Watch case, the combination of a case member andasheet of heat insulating material applied toy the casef'memberv eX- ternally and a protecting plate secured to ingfmaterial." f '1V '3; Ina Watch case, the'combination of a casemember and arprotecting' plate secured to the case member, Va sheet of insulating material applied to fthel external face of the case-member, and a protecting cap secured to the case member-.and havmgits edge restg ing against thesheet of insulating'materialV and out of contact With the case member.
