The lower tion' ofthe endfof the device; Y 50 surface 'of-the connector 2l Vis provided'with'a .Fig.,5is'a side" elevation of thev device with th rack tooth 28 adapted under the impulsion'of extension elements or connectors removed from springl'l to be kept'in engagement with oneor thei housing;VA another of therack teeth' il. 'As is usualwith "Eigxfis' a perspective View of an end of one the operation of racks, teeth Il and the tooth 28 ofthe Connectors; rf; d6 are so constructed that the rack plate I5 `canbe end of the casing shown in Fig. 4 and numbered' 29 is pivotally mounted on a shaft 3U and is constructed as a part separate from the casing but forming, when in position, a continuation thereof. The top of this pivoted portion of the casing is provided with an upwardly extending lip 3| which can be engaged by the finger to pivot this portion. This pivoted portion of the casing is provided with forwardly extending fingers 32 which are normally adapted to extend under a shoulder 33 suitably formed in the turned-over end of the connector 2 I. I will be apparent that when the finger engages the lip 3| to move it to the right, as
shown in Fig. 4, the fingers 32 will be elevated and carry with them the folded connectors 2D and 2| lifting them against the resistance of spring 21,
lfront end of this rack plate to the position shown in Fig. 5 or further and thereby provide a greater `length of band. When the connectors are folded within the casing, it is also to be noted that the degree to which the rack plate is pushed into the housing may well determine the tightness with which the band encircles the body member, since this plate is connected to an adjacent link of the band.
The purpose of displacing the connectors and 2| from the housing is to temporarily greatly expand the length of the band so that it can be easily removed from or disposed on a wrist or other body member which it is to encircle. After the band is disposed thereon, then the links are folded and moved back into the housing and the rack plate is moved as far into the housing vas is necessary to cause the band to properly and snugly embrace the body member. This adjustment. of the rack plate can be made very finely by reason of the engagement of the tooth 28 with any one of the teeth on the rack plate. A mere ip of the finger on the lip 3| will permit the rack plate to be moved back a suihcient distance to permit the removal of the connectors out of the housing. In the movement of the folded connectors back into the housing, it is clear that the turned-over end of the connector 2| on which the shoulder 33 is formed will slip `past the fingers 32 which are resiliently mounted and will then snap under the shoulders as shown in Fig. 4. The spring 21 will maintain the parts in engaged position until the disengagement thereof is positively effected by the lifting of the ngers 32 in the manner above described.
It is therefore obvious that the device is compact, durable, strong and composed of a minimum number of simple parts which definitely cooperate `to permit the removal of the device from a body member with ease and the attachment of said device to said member with equal dispatch and the final adjustment of the device on the body member with any desired degree of snugness.
While the invention has been described in detail and shown with respect to the accompanying drawing, it is not to be limited to such details,
since many changes and modifications may be made in the invention without departing from the spirit and scope thereof. Hence, it is desired to cover any and all forms and modifications of the invention which may come within the language and scope of any one or more of the appended claims.
