UNITED STATES LEWI LUBIN, OF BROOKLYN, NEW YORK.

WATCHCASE.

Application led February 16, 1922. Serial No. 537,053.

T 0 all whom t may concern.:

Beit known that I, LEwI LUBIN, a citizen of Poland, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of, New York, have invented a new and Improved Watchcase, of which the following is a full, clear, and exact description.

This invention relates to improvements in watch cases, and more particularly to an improved full movement frame for watch cases, an object of the invention being to provide a movement frame which snugly fits within the watch case and which supports the movement and is capable of ready removal from the watch case to facilitate access to the movement for repairing the latter.

Wvith watches as heretofore made a great difficulty has been experienced in repairing small movements,such as employed in ladies wrist watches because the balance stall'I of the movement is apt to be destroyed or injured by removing or replacing the same in ther-ase, and it is the purpose of my invention to provide a movement frame which supports the movement, which fits the case and which is capable of ready removal carrying with it the movement, so that the movement can be repaired without the necessity of removing the'movement from the frame. l

This is designed as an improvement upon the structure disclosed in my Patent No. 1,376,776, granted May 3, 1921..

With these and other objects in view the invention consists in certain novel features of construction, and combinations and arrangements of parts as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings- Figure 1 is a front view showing a wrist watch on an enlarged scale, in which my im roved movement frame is located.

igure 2 is' a rear view of Figure 1.

Figure 3 is a view in elevation showing the back of the watch case in open position.

Figure 4 is an exag rated View in' longitudinal section throug the watch case and movement frame, the movement being-omitf ted. f

Figure 5 is an inner face view of the case front.

Figure 6 is an inner face view of the case back. l

Figure 7 is a plan view of a case lining or band.

Figure 8 is a plan view of my improved movement frame.

Figure 9 is a view in transverse section on theV line 99 of Figure 8.

1 and 2 represent the case front and case back back respectively of my improved watch case, and it'will be noted that I have illustrated an elongated form of Watch case which is very attractive form of watch case in general use in connection with ladies wrist watches. A

Within the case front 1 I secure a lining or band 3 which projects beyond the edge of the case front and constitutes a flange, over which the case back snugly fits, and is held by means of a lug 4 over which the recessed end 5 of the case back is snapped.

6 represents my improved movement frame which conforms in exterior shape or outline to the internal shape of the watch case and is of asize to snugly lit within the lining 3.

It is, of course, to be understood that the particular. external shape of the frame is to be varied in accordance with the shapetof the case into which it is to fit, and that the invention is not limited to the particular shape of case and movement frame shown.

The movement frame 6 is hollow and comprises a single member, although it may be composed of parallel plates 7 and 8 soldered or otherwise secured to an outline strip 9, or otherwise formed as may be desired. It is to be understood that the movement frame will be light in weight, yet sufficiently strong to perform its functions.

This movement frame in Lits opposite walls is provided with openings 410 and 11 respectively. These openings are concen tric, but the opening 10 is appreciably larger than the opening 11, so that the movement 12 can be readily inserted into the frame through the opening 10 and conned in the frame by reason ofthe fact that the opening'll is too small in diameter for the movement to be forcedtherethrough.

It is to be understood, of course, that the movement 12 is of the same diameter as the opening 10 tosnugly fit within the frame and may be secured therein in any approved manner.

The winding stem 13 of the movement 12 is projected through an opening 14 in the frame 6 and through the 'lining 3 and case front 1 and is provided with the ordinary crown\l5. This crown 15 must, of course, be removed before the movement can be inserted or removed from the frame.

It is to be understood that after the movement is once inserted in the movement frame, it is not ordinarily necessary to ever remove the movement from the frame. In the event it is necessary or desirable to remove the movement from the Watch case, the movement frame 6 is removed from the oase and carries with it the movement and permits repair of the movement and access toboth sides of the movement Without disconnecting the movement from the movement frame. This is of great importance in repairing small Watches with delicate balances, because such balances are easily injured if the movement itself is handled and is forced out of and into the ordinary case in common use.

With my improved movement frame the movementl becomes, in eect, a part thereof after having been once inserted in the frame and the frame can be easily handled and removed and replaced Without disturbing the balance of the movement. To facilitate the removal of the movement frame, the lining or band 13 is provided at diametric'ally opposite points With recesses 16 fo-r the insertion of a suitable tool to force the movement frame out of the case.

it is obvious that various changes might be made in the external shape of the move- .ment-frame, as it is to be understood that the movement frame will conform to t-he shape of the Watch case, and it is also to be vunderstood that various changes might be made in the general form and arrangement of the parts Without departing from my invention. I, therefore, do not limit myself to the precise details of construction set forth, but consider myself atlberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claims.

I claim:

1. The combination with a Watch case comprising a case front and a case back, constituting a complete enclosure, of a lining band snugly fitting the case backfand having an edge projecting beyond the edge of the case back, which constitutes a flange over which the case front snugly fits, a lug on said band, said back having a recess into which said lug projects to hold the band in place, and a movement frame conforming in shape to the interior space of the band disposed Within the lining band.

2. The combination with a Watch case comprising a case front and a case back,

constituting a complete enclosure, of a 1ining b'and snugly fitting the case back and having an edge projecting beyond the edgey of the case back, Which constitutes a iiange over Which the case front snugly fits, a lug `on said band, said back having a recess into
