In a single lens reflex camera, when viewing the image of scales 16, 18 in the eye-piece (not shown), light from the scales falls on a section 20a of a focusing screen 20, which is outside the effective exit pupil of the objective defined by lines 20b, -so that the image of the scales may be viewed independently of the brightness of the object viewed. Shutter speed is adjusted by a knob 17 connected to scale 18, and the lens aperture is adjusted by a ring (not shown) which rotates a ring 13 and thus scale 16 through a cable 14. Light 41 from a window 21 is reflected by a mirror 23 to illuminate the scale values at 40, which are projected on to screen 20 by a mirror 33, prism 37 and lens 38. To project the image to the eye-piece, section 20a may be planar, spherical or bonded to the lower surface of a condenser lens (not shown). Depressing shutter release 31 rotates mirror 23 to block window 21, and inclines mirror 33 to bring the scale image into the picture area on the film, when reflex mirror 19 is swung up (e.g. by connection with mirror 23). A lamp 42 is flashed upon shutter operation. Mirror 33 may be fixed and the scales recorded outside the picture area, the picture frame mask being cut away. Other scales e.g. a date indicator may be recorded. The scales may be viewed within the view-finder field in which case section 20a is preferably transparent when the screen 20 has a matt surface.

Title: Improvements in means for equalising the effective force exerted by the piston of a diesel or like engine
IPC: F02B75/06
Filed: 1924-08-19
Abstract: 243,059. Mauss, W. Aug. 19, 1924. Driving-gear.-Means for opposing the outward movement of a single-acting piston and assisting the inward movement, in a high-pressure internal-combustion engine, consists of toggles acted on by fluid-pressure pistons in a direction at right angles to the movement of the main piston. The toggle links 5, Fig. 11, act directly on the main piston 2 and on a stationary abutment 9, adjustable by a wedge. The knuckles of the toggles are acted on by pistons 3 in cylinders 4, which are in communication with a reservoir containing compressed air. The cylinders slide vertically in guides 10. In a modification the toggle links act on the rods of pistons 20, 20a, Fig V, which move oppositely, and act on the main piston 2 by means of liquid contained in a casing 17. The angularity of the toggle links can be varied by allowing liquid to enter or leave the casing 17, by means of a cock 27 and oppositely acting check valves 28, 29, communicating with a vessel 26 containing liquid acted on by air pressure. The pressure of the toggle can also be varied by varying -the pressure acting on the pistons 3. In the case of a four-stroke engine, the pistons 3 force air into the reservoir 11 during the power stroke, while during the exhaust and suction strokes a cam 34, operates a valve 33, to put the cylinders 4 in communication with the atmosphere.

[Class 80 (ii).] Relates to gears of the kind in which the drive is transmitted to the driven shaft by means of a radially adjustabe pin and ratchets and consists in means, both manual and automatic, for adjusting the pin. The pin 5 is mounted on a screw spindle 6 carried by a disc 2 loose on the driving shaft 1, and coupled by torque-responsive springs 4 to a disc 3 fast on the shaft. The spindle is connected by a train of gears 9, 11, 10 with a spindle 12 carrying a bevel wheel 13 in mesh with bevel wheels 14, 15. A pull rod 20 connects a hand-lever 22 with a brake ring 21 which may thus be caused to engage either of the wheels 14, 15. When this occurs, the spindles 12, 6 are rotated and the pin 5 is moved radially. The ratchet devices 30, 31 are operated by means of slotted levers 28 through which the pin passes. In a modified construction, Fig. 3, the pin 106 is shifted by bevel gears 107, 108 driven by a pinion 109 in mesh with wheels 117, 118. A double wedge ring 115 surrounding the drive shaft 101 is adapted to be shifted axially by pins 110 and springs 114 so as to engage either wheel. The pins are carried by slides 102 on one end of which is mounted a threaded ring 103 in the hub of a disc 105 carrying the pin 106. A disc 104 is fast on the shaft and is coupled to the disc 105 by torque-responsive springs 126. Variations in load cause relative motion between the discs which causes axial movement of the slides and therefore of the ring 115 so that the bevel gear is operated and the pin 105 adjusted. For manual control a box 120 is provided containing a train of gears 121 .. 124 the last of which is screwed to a loose bush 112, and the first keyed on the shaft. Normally the box is held stationary by means of a hand-brake or the like. Gear changes may be effected by moving the box sidewise by means of a lever at 125, the movement being transmitted to the ring 115 by the bush 112. If a constant speed of the driven shaft is required the lever is shifted for the desired speed and the brake released.
