4 Claims. 1

My invention relates to watch band terminals for wrist bands for watches, and the object is to provide a terminal that will secure to the band a watch provided with rings or eyelets for attachment.

Another object of the invention is to provide the band with terminals having two relatively movable latching members, both actuated by the same means.

In the appended drawing, forming part of this application,

Figure 1 is a section on line i-l, Figure 4,

showing the terminal in locked position;

Figure 2 is a similar section on line 22, Figure 3, showing the terminal open;

Fi ure 3 is a section on line 3-3, Figure 1, in the direction of the arrow on the top of the figure;

Figure 4 is a section on line l l in the direction of the arrow at the bottom of the figure;

Figure 5 is an edge elevation of the liner;

Figure 6 is a, plan of the movable arm; and

Figure '7 is an edge elevation of same.

Referring to the drawings, a liner it formed of a plate having a semi-circular edge II, from which edge a fixed arm l2 extends co-planar with the rest of the plate but disposed towards one side. The arm 52 on the inner face and near the end thereof and towards the inward edge has a flange l3 rising at right angles to the plane of the plate. Preferably the outer surface of said flange I3 is fl sh with the edge from which it rises.

Pivoted on the inner face of the liner it with one end thereof is an L-shaped lever 14. The pivoted leg E5 of the lever is within the area of the arm l2 except of the pivot 16, which is located near the junction of the arm with the semicircular edge H. The other leg ll of the L- shaped lever extends through an opening is in the flange is. To properly centralize the open? ing 58 with the leg H, a spacer I9 is provided between the end of leg :5 and the liner IE at the pivot H5.

The liner ii! has a collar 28 rising from the inner face thereof and concentric with the semicircular edge ll of the liner it. See Figures 3, 4, and 5. An arm 2! having the contour of the fixed arm 12 is provided with an extension 22 ofiset laterally of the arm 2! to permit said extension to lie on the outer face of the liner 5 5 with the arm 2| being directly opposite and co-planar with the fixed arm of the liner. See Figures 6 and 7.

The extension 22 has a bore 23 of the same diameter as the bore of the collar 29 to accommodate a rivet 2 whereby the arm 2! is connected pivotally to the liner in to swing to and from the fixed arm i2 along the semi-circular edge H. The swinging movement of the arm 2| on the liner I0 is limited by the engagement of a lug 25 rising from the extension 22 of the arm 2| with a slot 26 in the liner Ill, as best seen in Figures 1, 2 and 7.

The edge of the arm 2! proximate to the fixed arm 52 has a flange 2! similar to flange l3 on the arm l2 and in alinement therewith. The-flange 2'! is provided with an aperture 28 to receive the end 29 of the leg ll of the L-shaped lever M.

This end 29 has a notch 29 adapted to engage the inner face of the flange 21' of the swinging arm 2 I.

Mounted on the outside of the collar 20 is a helical spring 32, one end 31' of which engages the lug 25 of the pivoted arm 2|, while the other end 32 of the spring 30 engages a notch 33 in the leg 15 of the L-shaped lever M. The tendency of the spring 30 is normally to move the L-lever l4 and the pivoted arm 2| apart but prevented from so doing in the closed position of' the terminal by the latching of the movable arm 2! with the L- lever I5.

The liner I 9 with its fixed arm l2 receives a cover or top 34, which cover on the open side has notches (not shown) to engage and rest on shoulders 35 (see Figure 5), and the liner II! also has depressions 35, see Figures 1 and 2, to accommodate the tongues (not shown) by means of which the cover is locked to the liner. A cover 3? is also provided for the arm 2!, that is to say, that portion of the arm which extends past the curved edge of the liner H3. Said arm has at the end thereof shoulders 38 for engaging the corres onding notch in the open end of the cover 31.

The arm 2! has also depressions 39 to house the the arm. These tongues are not shown in the drawing.

The liner In on the inner face thereof and near the straight edges extending from the semi-circular portion thereof is provided with ears 4!), substantially in alinement on an axis that is par allel to the straight edge ii of the liner. The aperture 42 in the ears forms means for attaching the terminal to a band.

The terminal in closed position has the two arms i2 and 2! spanned by the leg I! of the L- lever M. The notch 29' at the end 29 of the leg I! is engaged by the flange 2! through the aperture 28; see Figure 1. To open the terminal either to remove or to attach a watch to the terminal, the leg I I of the L-lever is pressed to move against the resistance of the spring 30, thus pivoting the L-lever M on the pivot 16 to disengage notched end 29 of leg I! from flange 2! of the swinging arm 2|, thereby permitting the swinging arm 2| and the L-lever M to separate. See Figure 2. In said figure the L-lever is shown in position when the notched end 29 has just released the arm 2| by the disengagement of said notched end 29 of the leg I! from the flange 27. The movement of the L-lever on the pivot l6 away from the s inging arm 2| is limited by the engagement of the leg I! with the edge of the aperture iii in the flange l3 near the end of the fixed arm l2.

To span the gap between the fixed arm l2 and the s inging arm 2| in closing the teminal, the arm 2| is moved to engage the notched end 29 of the leg I! of the L-lever l4. bringing the ap-- ertured flan e 21 of the pivoted arm 2! into engagement with the notched end 29 of the leg H, which causes the said L-lever to move on its pivot l6 and bring the notch 29' in latching position with the said flange 21 of the swinging arm.

I claim:

'1. A band terminal comprising a liner having a fixed arm to one side thereof and co-planar with the liner, a second arm pivoted to the liner to swing to and from the fixed arm and oo-planar with said fixed arm, means for limiting the movement of the pivoted arm on the liner and providing a gap between the arms, a latch pivoted on the liner and extending from the fixed arm towards the pivoted arm, a helical spring mounted on the liner and having its ends connected respectively to the latch and to the pivoted arm, said spring normally tending to move said latch and arm apart, said latch and pivoted arm having coupling means adapted to interlock by the action of said spring, whereby the gap between the arms is spanned by said latch, said latch being adapted to disengage the pivoted arm when it is moved against the resistance of the spring, a cover for the liner with its fixed arm, and a cover for the pivoted arm.

2.
