Letters Patent No. 95,128, dated September 21, 1869.

IMPROVEMENT IN WATCHES.

The' Sbhedule referred to in these Letters Patent and making part of the same.

To all 'whom 'it may concern Be it known that I, CHARLES S. MosnLEY, of E1- companyingdrawngs, making part of this specification,

in which- Figure 3 is a view in which the barrel-bridge is removed.

.Figure lis a section,- through red linea: y. Figure 2 is a ont or side view. 1

The running-parts of the watch are not shown in any ofthe gures.

, The object of my invention is, the exclusion of dust from the watch-movement.

To enable others skilled'in the art to-Inake and use my improvement, I proceed to describe its construction and operation.

In the drawings- A represents the pillar-plate, and B, the top plate of a watch.

These plates are made in the usual manner, except.

That part C which rests upon the top plate is ofthe usual form; but at right angles withv this part C, is a thin piece, c, extending tothe pillar-plate, and having a projection, d, which passes over the barrel.

The barrel-bridge (with the additional parts c d attached) is made from a single piece of metal.

The dotted lines (ig.2) indicate the position ofthe ends of c.

It is evident that when the barrel-bridge is constructed as described, that part lettered c (Z, so far as it extends around 'the edge ofthe movement, protects the same from dust.

rIhe protection is rendered complete by the use of two short, thin strips or ribbons of metal, a a, of such Width as to fit into the grooves b b', and of' such length as to reach' from the edges of the' part c of the bridge C around far enough to have their ends meet on the opposite side; Y

These strips, or ribbons, may be made of brass, rolled out thin, or of the same material that watch# springs are made of, they being made' suliiciently lexble to adapt themselves to the curve of the grooves b b.

These two strips'a a, when thus inserted, together lwith' the projecting portion c of the-bridge C, form a protection, enclosing the works, and excluding dust and dirt therefrom.

The outer ends of the strips aY a are to be provided with a hole', or projection, into or against which .to place anyisuitable instrument for removing the strips, when necessary.

, 'It is obvious that, if preferred, the two strips a a maybe made inrone piece, instead of two, and used in the same manner. In any event-,the ends should fit snugly against the sides of the part c of the bridge G, so as Ato make a tight joint at that point.

I am aware that so-called dust-rings are used;

lbut my device has several advantages over these. It

is more compact, and accomplishes the object more ei'eciively.

Having thus fully described my invention,

. -What I claim as new, and desire to secure by Letters Patent, is as follows:

1. 'The'combnation of the bridge C, provided with the lip c and the strips a., when arranged substantially as described. v

2. 4Providing the plates A B with grooves b b', substantially as and for the purposespspeciied.

3. The metallic strips a a, in combination with the plates A B, having the grooves b b', substantially as and for the purposes'specied.
