Patent GB-1526185-A (GB)
Title: Camera
IPC: G03B17/42
Filed: 1977-03-11
Abstract: 1526185 Camera mechanism FRANKE & HEIDECKE GmbH [trading as ROLLEI-WERKE FRANKE & HEIDECKE] 11 March 1977 [28 May 1976] 10377/77 Heading G2A A camera has a handle which moves out of, and back to, a basic position transversely to the optical axis for winding and shutter cocking, the handle being engageable with a rack which drives the film winding shaft and also being engageable with a cover plate which moves to cover or uncover the lens and/or viewfinder. The Figs. show the mechanism in the basic position. The handle 7, in the form of a slider, is at the extreme right of its path, the cover plate 10 covers both the viewfinder 2 and the lens opening 3, and the shutter drive slider is retained in the cocked position by a pawl 53. The end of a feeler lever 42, Fig. 5 (not shown) resets on the film (57). If the slider 7 moves to the left, a hook 16 at one end engages and moves the rack 18 similarly. The movement of the rack, via a train of gears 61-64, rotates the wheel 59 which winds on the film. The end of the feeler lever 42, Fig. 5 (not shown) drops into a perforation (68) in the film, so that the lever is pivoted clockwise and blocks further film movement. At the same time a slider 8 rigid with the slider 7 engages and pushes the cover plate 10 to the left, uncovering the openings 2 and 3. The camera is now ready to make an exposure. If, however, it is decided not to make an exposure, and the openings 2 and 3 are to be blocked again, slider 7 is moved to the right again, to the Fig. 2 position. Rack 18 also moves back again, but the gear train 61-64 includes a slip clutch arrangement, so that the film winding wheel 59 is unaffected. Slider 8 entrains the cover plate 10 and moves it back to its Fig. 2 position. Mechanism is provided whereby in this position the rack 18 and the slider 8 come out of engagement. If an exposure is to be made, slider 7 is moved to the left as before, and the previously described sequence of moves repeated. The release button 5 is pressed, which pivots the pawl 53 clockwise, releasing the shutter slider 45, which runs off to the left under the action of a spring 46. A dog 51 on the slider strikes an arm of the shutter blade 48, and pivots it briefly to uncover the exposure aperture. To make a further exposure, or to return the camera to the rest position, sliders 7 and 8 are moved back to the Fig. 2 position, which also cocks the shutter again.

Abstract: 419,860. Steady rests. HAHN, H., HAHN, O., and TESSKY, K., (trading as INDEX-WERKE HAHN & KOLB), Esslingenon-Neckar, Germany. April 11, 1934, No. 10872. Convention date, May 4, 1933. [Class 83 (iii).] A guide bush 6 mounted in the end of a lathe spindle 1 to form a rotary steady rest for bar stock is slotted from opposite ends at 7, 8 and is provided with tapered ends co-operating with cones 3, 5 provided respectively in a cap 2 screwed on the spindle 1 and in a collar 4 screwing on the cap 2. Adjustment of the collar 4 varies the internal diameter of the bush 6 to the exact size of the bar stock, and locking is effected by a nut 9. The bush 6 may be reversed in the spindle when the outer end of the bore has become worn, but in a non- reversible modification, the bush is tapered at one end only. In a further modification, the conical surface 5, Fig. 3, is formed in the cap 2 screwing on the spindle 1 and the conical surface 3 is formed on a bush 12 resiliently pressed by springs 13 so as to allow the diameter of the bore in the bush 6 to vary automatically to suit variations in the bar stock. The springs 13 are seated in a ring 14, the bush 12 being accurately centred by the ring 14 and the ring by the cap 2. The bar stock is fed through the bush 6 during machining and the bush is made of hard bronze or other hard non-ferrous metal so as not to sieze on the bar stock or score it during feeding. The device may also be incorporated in a steady rest mounted in front of the lathe spindle and rotated from the latter.

Fig. 1 shows a battery in which the bottom cell which may be made of steel for strength is formed with hooks 7 at its rounded corners, the top cell being closed by a steel dish 8 having projections 10 and a terminal lug 9 as shown in Fig. 4. The dish may be provided with a carbon coating so that it forms an electrode of the top cell. The end of a thread 11 may be secured by pinching one of the hooks 7 upon it. The thread is then passed over the top edge of the dish 8 and down to another of the hooks 7, then across the bottom cell to a, third hook 7 and up to the top of the battery and down to the fourth hook 7 which - is pinched to secure this end of the thread. The battery may finally be coated with paraffin wax and enclosed in a rubber or plastic sleeve. Alternatively the battery may be waxed and sheathed and the thread binding applied outside the sheathing. In a modification the thread-retaining devices are not carried by the end cells but are formed 'on separate steel plates as shown in Fig. 5. Lugs 14 help to locate the thread in addition to the corner hooks 13. Fig. 6 shows a modification of the dish shown in Fig. 4 in which the lugs 10 are replaced by notches 16.

[Also in Divisions E2 and H3] The motion of a tuning knob 6 is stopped and locked by a mechanism included within the knob. Stopping is provided by eccentrically mounted gearing 4 which engages within slots on a stator 5 connected to the knob 6 and the locking mechanism consists of a spring 1 also connected to the knob such that a wedge 31 can be inserted into the spring to expand it against the walls of a braking case 2 rigidly connected to a panel 9, when the lever 3 is pivoted about 33 in the position shown. Release of the locking means occurs when the lever 3 is pivoted out from the knob (Fig. 9, not shown), where it provides a handle for rapid rotation of the knob. The stopping mechanism consists of two gear wheels (41, 45, Fig. 3, not shown), connected together and arranged to rotate about the braking case 2 so that when a tooth 42 on the top wheel (45) engages the solid wall of the stator 5, rotation of the knob is stopped; this corresponds to one of the end stop positions.
