Specification of Letters Patent. Patented Apr. 26, 1 910.
' Application filed August 25, 1909. 1 Serial No. 514,579.,
the ocular-sof which, for being adaptable.
to the interpupillary distance ot' the ob; server, are mounted so as to be each-rotatable about an axis parallel to the axis of the emerging rays. In most cases, the two oculars of such .a'dou'ble telescope are connected in such a manner. thatb) rotating one of them about its eccentric axis of rotatlon the other is taken along by an equal .angle in thevopposite direction. .The niost simple connection hitherto employed for this purpose consists in each ocular being titted with a toothed rim concentric to its axis of rotation and engaging the corresponding rim of the other ocular.
The present invention consists in particularl v simple and cheap means for connecting the ocnlars. 'lhe toothed rims concentric to the axes of rotation of the oculars are replaced by likewise concentric drums aml crossed bands tixed on these drums.
in the annexed drawing: Figure 1 is,a sectional plan view of a double telescope constructed according to the Fig. .2 is a vertical section on the line 2-2 of l ig. 1.
The axes of rotation of the oculars ll coincide with the axes of the objectives I). In
eachocular, the eccentricity of the exit axis to the axis of rotation may result from an image-erecting prism system arranged in the case c. There are two drums d concentric invent ion.
to the axes of rotation of the oeulars a and rigidly connected with the latter. In the example shown, each drum comprises only a single drum surface. vThe two crossed bands 0 and f areshown as being made in one piece, a being slotted in its middle portionand f narrowed in the same portion, so that, in the crossing point, f can ass throughthe slot of e. The bands are red to the'drums (l by means of screws g.
I claim: 1. The combination; with the optical pa of a double telescope, of two front casings rigidly connected together, two hinder easings rotatably mounted on the front casings, the axis of rotation of each hinder casing bein}; eccentric to the optical exit axis, and both eceentricities being equal, two drums having the same diameter and being mounted on the hinder casings concentrically to the axes of rotation and crossing. bands fixed to both drums.
2. The combination, with the optical parts of a double telescope. of two front casings rigidly connected together, two hmder casings rotatably mounted on the front casing, the axis of rotation of each hinder casin being eccentric to the optical exit axis, an
both ecceutricities being equal. two drums having the same diameter and being mounted on the hinder casings concentrically to the axes ot'rotatiou and crossing bands fixed to both drums aml made in one piece, the
middle portion of one band being slottedand the middle'portion of the othernd narrowed.
