WATCHCASE.

Application led August 14, 1922. Serial No. 581,802.

To all whom t may cof/teem.'

Be it known that I, Josemi LAsiio, a citizen of the United States, residing at 309 Grand Street, borough of Manhattan, city of New York, have invented a new and useful Improvement in Watchcases, of which the following is a specification.

This invention relates to improvements in watch cases and more particularly to that class known to the trade as two-piece cases such as are commonly used on wrist watches.

One of the objects of the invention is to provide a case wherein it is possible to examine the inner surface of the back cover of the case and the watch movement without the necessity of removing the movement from its position in the case.

Heretofore in the assembling of such watches, it has been customary to support the movement in the back cover of the case in Such a manner that when the case was opened, the dial face and the inner surface of the front cover only were visible, thus necessitating the removal of the movement from the case if it was desired to expose the movement and indices on the case.

Another object of the invention is to provide for snugly encasing the movement within the front cover of the case and to exclude dust and other foreign particles from entering into the spaces ordinarily eX- isting between the circumference of the movement and the encompassing cover. This object is achieved by providing a loose ring, shaped externally to fit snugly within the watch case and shaped internally to fit snugly around the movement. f

As a further object the invention contemplates the provision of a novel means for holding the case closed, which also acts to hold the ribbon or wrist band connected to the case.

With these and other objects in View which will become more apparent as the description proceeds, 'the invention consists in the novel construction, combination and arrangement of parts which will be fully set forth in the following specification, and illustrated in the accompanying drawing, in which,

Figure 1 is a face View of this improved watch case, showing the dial face, the movement being in place,

Figure 2 is a rear view of Figure 1 showing the case open, and disclosing the movement,

Figure 3 is aface View of the ring adapter, Figure 4 is an edge view partly in section of Figure 3, and

Figure 5 is an enlarged fragmentary sectional view of the case illustrating in detail the means for holding the same closed.

Referring to the drawings in detail, the numeral 10 designates in its entirety the watch case which comprises the front and back covers 11 and 12 respectively, hinged together as at 13. The front cover 11, is provided adjacent the hinge 13 with a loop 14 through which the wrist band or ribbon (not shown) is passed, and secured to the front cover. At the opposite side is a similar loop 15, the ends of whichvare passed through openings 16 in the cover and turned outwardly as at 17 'to engage in indentations 19 formed adjacent the matching edge of the back cover 12.

Fitted into the front cover 11 is a ring adapter 20 shaped externally to fit the inner contour of the cover 11 and this ring is shaped internally to conform to and receive the watch movement 21. Formed near the outer edge of the ring 20 is an internal annular lanige 22 which acts in conjunction with the customary half head screws 23, to retain the movement 21 in place in the ring.

In use, it will be seen that the ring 20 is secured around the watch movement 21 and then the ring and movement are set into the front cover 11 of the case as a unit. Obviously, the ring will act to exclude dust and foreign substances from entering the movement and owing to its snug fit in the cover 11 will cause the movement to remain in said cover when the case is opened.

While in the foregoing there has been shown and described the preferred embodiment of this invention it is to be understood that certain minor changes in the details of construction, combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as claimed.

What is claimed is:

1. A watch case comprising a front cover, a back cover hinged thereto, a ring adapter removably secured in the front cover to support a watch movement, means to secure the movement in said adapter, ribbon attaching means at the sides of the front cover, and means associated with one oisaid attaching means for holding the Covers normally in closed relation.

2. A Watch case comprising a front cover, a back @over hinged thereto, ribbon securing means at opposite sides of 'the front @oven-and arms on one of the ribbon securing means for holding the front and back covers closed.

3. A combination Watch case, comprising two shells, a hinged joint bet-Ween said two shells, a removable ring fitting into one of said shells and releasable means adapted to keep said shells in a closed position, said means comprising two elastic wire pins axially set at the inside of the Wall of one of said shells and two (5o-operating recesses in the Wall of the other` shell.

4. In a Watch case, a shell adapted to receive the movement of the Watch, a second shell to be used as a. Cover for the first shell, Wire catches axially and yieldingly set at the inside of the Wall of one of said shells and impressions provided inthe Wall of the other shell and adapted to receive said wire catches and keep said two shells in a closed position thereby.
