1 Claim.
Our invention relates to terminals for wrist bands for watches, and the object of the invention is to provide terminals that will secure to a band watch cases of great differences in span between the facing arms of the case.
Another object of the invention is to provide terminals for wrist band ends which are simple and sturdy in construction and easy to attach, the moving parts of which terminals will not bind,
Generally the ends of a wrist band for a watch case terminate in a tube, into which expanding pins are fitted in accordance with the spread of the facing arms of the watch case. in consequence, it is necessary to stock with expanding pins of different lengths. Our object is to obviate this necessity and provide the ends of the band with expanding pins that will take care of the variety of watch cases generally encountered in the trade.
In the appended drawing, forming part of this application,
Figure 1 is a section of our terminal on line I-I, Figure 2;
Figure 2 is a cross-section on line 2-2, Figure l and Figure 3 is an end elevation of the terminal.
Referring to the drawings, 5 and 6 are the telescoping pins, each provided with a head 'I at the free end thereof. A sleeve 9 is provided for each pin, and it is secured to each head 'l by rolling a portion of its curved periphery into the annular groove 8 formed in the head 1 of the pin. The major part of the sleeve extends over the reciprocating part of the corresponding pin, and each sleeve is provided with an outwardly flaring flange l at the free end of said sleeve; the two flanges being proximate to one another to abut before the telescoping of the pins and 6 are at the end of the inward movement of the pins. A spring H is mounted within the sleeves 9 over the pins 5 and 6 normally to move the pins and sleeves apart.
Engaging the sleeves 9 is a drum I2 formed at each end of the band by rolling the material thereof into the shape, as best indicated in Figure 2, and turning over the edges of the material to form the ends of the drum. The inside diameter of the drum is substantially equal to the diameter of the flanges i0 of the sleeves 9, while the openings in the ends of the drum are substantially lequal lin diameter to theouter diameter of the sleeves 5, so that the sleeves can Cl. 2li- 265) be reciproeated within the drum by the spring l I without binding in the drum, because the telescoping pins act as axial guides for the sleeves. A trunnion la is provided at the end of each head projecting outwardly of the sleeve for engaging the facing arms of a watch case. The maximum expansion of the terminal is indicated by the dash and dot lines in Figure 1, and that is when the anges i0 but against the inner surface of the drum ends.
The provision of the telescoping pins as axial guides for the sleeves 9 prevents the binding of the sleeve within the drum l2 when the sleeves are mostly out of the drum under the action of the spring H, for in that position the flange l0 of each sleeve is in proximity of the end of the drum, and the telescoping pins maintain the sleeves in proper alinement with the drum at that time.
We claim:
In a wrist band terminal, a pair of telescoping pins, each provided with a head at its free end. a sleeve shorter than the pin for each head, each of said heads having an annular groove and one end of said sleeve having a portion of its curved periphery rolled into the annular groove of a corresponding head, so that the major part of the sleeve extends over the telescoping pin to which it is secured, each sleeve having an outward ange at the free end, a coil spring on said telescoping pins butting with its ends the heads of the pins, said spring being housed within said sleeves, a drum shaped member forming part of the band engaging the iianged ends of said sleeves, each of said sleeves passing through the corresponding end of the drum to permit said sleeve to telescope within the drum under the action of the spring, and a trunnion directed outwardly from the head of each pin and in alinement therewith.
