Claims.

This invention relates to an attachment for wrist watches and more particularly for combination with the spring lug pins in the ears of wrist watches.

It is an object of my invention to provide an attachment forming a belt clamp or the like for combination with the spring lug pins supported between ears of a wrist watch holding a wrist watch attached on the belt and to be clamped thereon instead of wearing on the wrist, the attachment including spring means normally urging the wrist watch supported upon a bracket of the clamp and permitting tilting of the watch when worn on the belt for ready inspection thereof, and alternatively including prop means combining with the clamp whereby the wrist watch may be braced in upright tilted position on a night table or the like, to form a stand for the wrist watch.

Still more particularly it is an object of my invention to provide an attachment forming a belt engaging clamp supporting a wrist watch for combination with the spring lug pins held between ears thereof and including a body of sheet material spaced into spaced branches joined resiliently by a loop to form a belt engaging clamp. In said device the branches comprise a front face clamp arm and a rear face clamp arm, a portion of said front face arm being shaped to form a tubular or ring-shaped bracket normally to sleeve over the spring lug trunnioned between the ears of the wrist watch. The clamp coordinately forms a base for the wrist watch, cooperating with a prop member pivotally supported on the opposed spring lug to brace the watch in a tilted position on a surface.

To attain these objects and such further objects as may appear herein, or be hereinafter pointed out, I make reference to the accompanying drawing forming a part hereof, in which:

Figure 1 is a perspective view showing my device with a fragmentary portion of the belt to which it is attached;

Figure 2 is a perspective view showing the watch tilted for inspection;

7 Figure 3 is a section taken on the line 3-3 of Figure 1;

Figure 4 is a magnified section taken on the line 44 of Figure 3;

Figure 5 is a section taken on the line 5-5 of Figure 4;

Figure 6 is a side elevation of the watch and attachment used as a travelling watch;

Figure 7 is a rear view taken in the direction of the lines 1-1 of Figure 6.

Summarizing my invention, it has as its object to provide a belt clamp having a bracket which may fit between the spring lug ears of a wrist watch to serve as the pivot about the spring lug pin normally used in the wrist watch and which serves as a pintle to convert the wrist watch from one worn on the wrist upon removal of the bracket bands to one which may be worn on the belt and in this position permitting tilting of the watch from a normally spring biased position against the body or belt to facilitate reading of the watch. Coordinately, the belt clamp attachment contemplated by me forms a base for the wrist watch, cooperating with a prop member attachable to the opposed spring lugs whereby a travelling watch supportable on a night stand or the like is secured.

Making reference to the drawing, I show a fragment of a waistband or garment belt Ill which may be used to support the wrist watch attachment H and which comprises a strip of sheet metal bent to provide spaced branches l2 and I3. joined by the loop l4 which normally biases the branches I2 and I3 toward each other. The rear face clamp arm I2 is died-out to form spaced arms l5 and I6, joined by the cross branch I1 and providing an abutting edge l8 and flared side edges l9 and 20, converging from the abutting edge for purposes which will appear as this description proceeds. The front face clamp arm II is generall ring shaped, having an aperture 2| through which the rear face clamp arm 12 is accessible. A cross arm 22 is formed adjacent the loop [4, supporting a bracket 23 of generally tubular contour, whose edges 24 may fit between the cars 25 of the wrist watch 26. The ears 25 normally employed trunnion the spring lug pin 21. The bracket 23 retains the helical spring 28, having one end 29 anchored in a slot 30. The opposite end 3| of the spring extends through a slot 32 to bear upon the edge 33 of the watch.

With the arrangement provided, the watch 26 is biased by the spring 28' to lie in contact with the front face clamp arm l3. The watch is mounted in inverted position upon the belt H], as shown more clearly in Figures 1 and 2 and when so worn, may be read merely by tilting the watch horizontally, as shown in Figure 2, for inspection.

When not in use the attachment includes a prop arm 34, having a sleeve 35 at one end, which may fit between the ears 36 of the wrist watch sleeved over the spring lug pin normally employed in this position to connect the bands of 3 a wrist watch strap. As in the prior embodiment, a spring 31 is retained within the sleeve 35 and has its opposite ends sprung to move the prop member 34 normally toward the back 38 of the watch. The prop 34 is formed with a leg portion 39 having a shoulder 40 which may fit between the branches I9 and 20 of the rear face clamp arm l2. When not in use as a wrist watch clamp support on the belt 10, the clamp may rest upon the surface S, as shown in Figure 6.

Tiltingthe Watch for reading as a travellingclock or night watch may be effected by pivoting the brace arm 34 against the resilient tension of the spring 31 until the leg portion fig'abuts the edge l8 and the shoulder portions 40 contact the 34 from moving to the collapsed position shown in Figure 2, bracing the wrist watch face'in-a' partially erect position.

Itvvill thusbe observed that RI "have provided an attachment 'forready combination with the spring lug pin and ears of awrist'watc'h, "and upon removal of the usual wrist watch bands, I may convert the watch to one which "may be worn on the belt oriin a similar att'a'chingp'osition. When worn as'shown-i'n Figures '1, 2*and 3', the watch is held against displacement bythe' clamping action of the rear "face clamp arm l2 and the front fac'eclamp arm f3.

Additionally'where the portion 39 engages the belt held between th'e arms l2 and I3, accidental, displacement of thewatch'fro'm the 'bltismini mized.

It willalso be' understood that while I show the prop arm '3 in a position *normally tending to bias the prop arm outwardly, a reverse biasing action is feasible provided'th'e spring '31'i's less intense than the spring action between theiarms l2 and I3, thereby cooperatingwithlthe clamp arm frictionallyto engage the belt'l Band further minimizing accidental displacement.

Having thusdescribed my invention andillustrated its use, what 'I claim as'ne'w'an'd desire to secure by Letters Patent, is:

1. An attachment forming a belt clamp or the like for combination with thespring lugs of a wrist watch comprising a strip having branches joinedby a loop to form a front face'clamp arm and a rear face clamp arm, the front face clamp arm having'a bracket adjacentsaid loop :to 'lie adjacent the spring lug ears of the Wrist watch and sleeved over the spring lug normally trunnioned between the ears, and "spring means biased against said clamp arm.
