摘要： A focusing system for long focal length objectives, having an intermediate tube between the camera and the objective proper. For purposes of focusing, there is a displaceable part movable longitudinally through the intermediate tube, and movement of this part serves to move the lens elements axially for focusing. A receiver portion on the bottom of the intermediate tube receives interchangeably, in quickly attachable and detachable manner, either one of two different focusing mechanisms, the first having the shape of a gun stock with a trigger-like member serving to focus the lens quickly but not necessarily precisely when quick picture shooting of moving objects is desired, the second mechanism having means for accurate focusing and a tripod thread socket. Provision is made for turning the camera 90 degrees to change the format of the picture. Mechanism is provided for pre-setting the diaphragm aperture, and for operating the diaphragm of the lens at the front end of the intermediate tube from the camera located at the rear end of the tube, with provision for adjusting these mechanisms properly when the camera is turned to change the format, without turning the objective at the front of the tube. It is not necessary to detach either the camera or the lens when changing from one focusing mechanism to the other, or when turning the camera to change the format.
摘要翻译： 用于长焦距物体的聚焦系统，在相机和物镜之间具有中间管。 为了聚焦的目的，存在可纵向移动通过中间管的可移动部分，并且该部分的运动用于轴向移动透镜元件用于聚焦。 中间管底部的接收器部分以可快速连接和可拆卸的方式可互换地接收两种不同的聚焦机构中的一种，第一种具有具有触发器构件的枪料形状，用于快速聚焦镜片， 不需要精确地当需要快速拍摄移动物体时，第二机构具有精确对焦的装置和三脚架螺纹插座。 提供了将相机转动90度以更改图像的格式。 提供了用于预先设置光阑孔径的机构，并且用于在位于管后端处的照相机上操作中间管前端处的透镜隔膜，当照相机为 转向改变格式，而不转动管前面的物镜。 从一个对焦机构更换到另一个时，或者转动相机以更改格式时，无需将相机或镜头分离。

摘要： The invention contemplates an improved binocular telescope construction of the variety wherein a bridge provides articulated connection of the two telescope systems, so that by folding at least one of these articulated systems back against a side of the bridge, the instrument may be compacted when not in use. The invention is particularly concerned with provision of a single focusing drive for the focusing optical elements of both telescope systems, the drive being operative regardless of the extent of articulated expansion or contraction of the bridge-connected systems. The invention also features provision of such focusing by movement of optical elements contained within the overall telescope-housing length, so that such length does not change in the course of focusing. Various embodiments are described.
