Title: Improvements in or relating to telescopes
IPC: G02B23/00
Filed: 1938-04-27
Abstract: 514,124. Telescopes. COOKE, TROUGHTON, AND SIMMS, Ltd., and TAYLOR, E.W. April 27, 1938, No. 12627. [Class 97 (i)] A telescope of the kind in which the main body containing the objective and eyepiece remains fixed, whilst an external mirror is provided for reflection of an external image along the line of sight which, by rotation of the mirror, may be varied between the vertical and the horizontal, has a prism or equivalent system of mirrors disposed between the eyepiece and the objective and having one roofed and one plane internal reflecting surface for erecting the image. The telescope may be monocular or binocular. As shown, between the objective 5 and its focusing eyepiece 7 there is a prism 15, which in side elevation appears as a parallelogram. This prism has a roofed top wall 17, and is disposed so that the light from the objective falls upon one of the interior surfaces of the prism roof 17 and is internally reflected from the one roof wall 17 to the other and is finally reflected to the plane base of the prism and thence to the eyepiece. The prism is held in position by a V-shaped clamping member 18. The end of the prism adjacent the eyepiece has a field stop-plate 19 of known construction arranged over it which carries fine wires, or alternatively cross-lines may be ruled on the adjacent face of the prism itself. The external mirror 13 occupies the full and dotted-line positions respectively for vertical and horizontal lines of sight, but intermediate settings of the mirror may be used. The reflected image of the object in the mirror 13 will be inverted while the objective will produce a further.inversion and a reversal from left to right, and the prism will produce a further reversal. In this way the final image viewed through the eyepiece will be totally erect. The mirror 13 may be silvered, or of stainless steel. The preferred parallelepipedonal prism has parallelogram sides with acute angles of substantially 45 degrees whilst the chamfering to produce the roofed surface is also substantially at 45 degrees.
