Title: Automatic control mechanism for linecasting machines
IPC: B41B27/10
Filed: 1965-10-28
Abstract: 1,131,471. Type-bar-making machines. MOHR LINO-SAW CO. 28 Oct., 1965 [28 Oct., 1964], No. 33693/65. Heading B6W. Control by record-strip; cutting slugs.-A line-casting machine is provided with a first mechanism to control the assembly of matrices and casting of slugs, and a second mechanism to control special functions such as setting of the slug saw, said mechanisms being actuated by signals in an information-bearing member such as a perforated tape, and a selection mechanism to render either said first or second mechanism responsive to signals and the other unresponsive, the selector mechanism being controlled also by signals. When a control blocking bar X, Fig. 2, is in normal position, the code bars CB control the push bars PB and levers 112 in normal manner. Two successive Upper Rail (UR) signals move the bar X to a position to block the normal operation of the bars PB, and move pairs of contacts CS 0 - CS 5 , Fig. 17, into position to be actuated by the bars CB, while information is stored in a command register. The bar X is restored by a Lower Rail (LR) signal, or by a solenoid RSO in certain abnormal conditions such as breaking of the tape T, the contacts CS being retracted and switch RSW being closed to reset the register. In particular, the slug-cutting saw S, Fig. 32, is set according to line length, and consequentially the jaw mechanism 460 and assembler mechanism 470 is also set, in response to the successive signals UR, UR, S, followed by figures giving the setting in picas and points. The position of the saw is communicated to a shaft 501, Fig. 33, and is detected by photocells and a light source 650 in conjunction with code dials PID (picas) and POD (points). The photo-cells control a reversible motor 530 to move the saw to its new position in response to voltage differences produced by the saw position and the number signals in the tape. The saw is kept stationary until casting is completed by a cycle switch CYSW, Fig. 42, co-operating with a cam 382. The travel of the saw is limited by switches ULS, LLS. In setting the saw, the motor 530 over-runs and reverses to the correct position. If two UR signals occur non-consecutively without an intervening LR signal, or if the tape breaks, a reject solenoid returns the bar X to normal position. The saw for cutting the slug to a desired width can also be controlled. The assembler elevator is prevented from operating except when the motor 530 is stationary. Until a slug has passed a photo-cell detector on the way to the galley, the following line is prevented from delivery to the first elevator by the operation of a detector DR, Fig. 22, which also controls the operation of the assembler elevator

Patent GB-337478-A (GB)
Abstract: 337,478. National Cash Register Co., Ltd., (National Cash Register Co.). Aug. 6, 1929. Hammer-impression arrangements. - In impression arrangements for cash registers and like machines having means for effecting two or more hammer-strokes during one cycle, independent hammer-operating means normally held in retracted position are released successively and are restored during one cycle. The platen 47, Figs. 1 and 3, is secured to a yoke 49, 50 pivoted on a stud 51 and provided with a cross-rod 53 which is held by means of a light spring 52 in contact with independent operating-means or bell-cranks 60, 61 pivoted on the stud. The bell-cranks 60, are restrained by a bail 65 secured to a rock-shaft 68 which is connected by linkage 80 to a rocker 84, Fig. 8, co-operating with cams 80, 81 on a shaft 82. Spring- urged detents 78, 79 pivoted on the shaft 68 have hooked ends adjacent to the bell-cranks, and shoulders 92, 93 in the path of the bail 65, the shoulder 92 being in advance of the shoulder 93. The movements of the bell-cranks are limited by a collar on the shaft 68, the bellcrank 61 having slightly greater movement than the bell-crank 60. On operation of the shaft 82, the cam 81 causes the bail to make three downward steps separated by pauses. During the first step the bell-cranks are released and permitted to engage the detents, and during the second step the bail engages the shoulder 92, thereby releasing the detent 78 and permitting the bell-crank 60 to operate the hammer. Thereupon the spring 52 retracts the hammer until the cross-rod 53 engages the bell-crank 60, and during the third step of the bail it engages the shoulder 93, the detent 79 being thereby released to permit of the bell-crank 61 operating the hammer. The cam 80 restores the bail in a continuous movement during which the bell-cranks are restored, the detents abutting on the ends of the bell-cranks until the latter are fully restored and then moving into normal position. To prevent operation of the hammer when no slip is present to receive the impressions, the device shown in Fig. 8 may be provided for locking the hammer until a slip is inserted in the shoot 31. The device comprises a rocking feeler 149 connected to an arm 151 engaging a pin 152 on a latch 146 which is pivoted on the bail-operating link 89 and co-operates with a stop 148. The link 89 has a slot 141 engaging a pin 87 on the rocker 86, a spring 142 being arranged between the pin and a pin 143 on the link. When no slip is present, the latch engages the stop and blocks the link, the pin 87 moving idly in the slot 141. When however a slip is inserted, the feeler and the arm 151 are raised and the latch is released, thereby permitting operation of the hammer. The shaft 68 may be provided with a hook 144 which engages a pin 145 on the yoke 49 to bold the hammer in retracted position, the hook being released when the shaft is rocked. The hammer may be adapted to give more than two impressions, and in machines having a set of hammers selectively operated for column-printing, each hammer may be associated with the above-described mechanism.

Title: Portable stroboscopic apparatus
IPC: G01P3/40
Filed: 1936-12-09
Abstract: 474,554. Stroboscopes. OEHMICHEN, E. E. Dec. 9, 1936, No. 33865. [Class 97 (i)] Portable stroboscopic apparatus having adjustment of the sharpness and luminosity of vision and binocular vision by observation through regularly spaced openings in the circumference of a disc, to which a mechanical movement imparts a controllable rotary movement, and wherein the speed of the disc is obtained by observing the position of a pointer which moves in front of the divisions of a dial, is characterized in that a governor is operatively associated with the pointer by a lever co-operating with a cam secured to the pointer and carrying a member co-operating with the governor. In the form shown in Fig. 1, the apertures 12, 12<1> register with the openings in the disc 8 shown separately in Fig. 3. Of the four openings 19 one two or all may be exposed by suitably positioning by the knob 13, Fig. 1, the openings 17 of the concentric selector disc 9. The index 10 observed through the window 20 shows the number exposed. The openings can be partially closed by a small relative movement of the discs 8 and 9. The knob 7 locks the disc 8. The speed control device is shown in Fig. 9. The knob 14, Fig. 1, rotates by gearing 50, 51, the axle 48 carrying the pointer 49 moving over the scale 15, and the cam 47 which operates the lever 41, 42 with a friction pad 44 engaging the plate 39 of the governor. The two parts 41, 42 of the intermediate lever are fixed by the screw 52 and are relatively adjustable to give the correct zero setting of the pointer. Figs. 10 and 11 show a device for adjusting the relative settings of the discs 8 and 9 while both are rotating. The pin 56 on the disc 8 projects through an arcuate slot 57 in the disc 9. Two spring loaded plungers in chambers 58, 59 prevent the passage of the pin 56 more than halfway on the slot 57 until sufficient force is applied. Movement of the pointer 64 brakes one of the discs 8, 9, through springs 60, 61. If it is moved to position 2 and released the selector disc 8 is retarded and the pin 56 moves forward to the spring plungers to give position 2 for the disc 9. If pointer 64 is moved to 4 the selector disc is braked hard and the pin 56 forces the spring plungers apart to give position 4. To return to position 1 the pointer 64 is placed on 1, when the disc 8 is braked and the disc 9 moves forward by inertia. The spring plungers may be shaped to facilitate the return movement. The Specification also contains a description of a movable masking plate with narrow slits to limit the size of the observation apertures 12, 12<1> and outlines a differential arrangement with two stroboscopic discs rotating at different speeds. A discussion is also given of the appearance of a periodic motion when observed stroboscopically with a frequency which is a multiple or sub-multiple of that of the observed object. Specification 114,830 is referred to.

Abstract: 1292246 Latches EWALD WITTE & CO 20 July 1971 [3 Sept 1970] 33943/71 Heading E2A The bifurcated latch bolt 20 of a vehicle door is fastened by a lever-detent 25 which may be rocked clockwise to the releasing position by axial movement of a push-rod 9 under pressure from end 6 of a manually operated lever 5 acting on arm 7 on the rod, this rod also having a forked arm 8 at its end by means of which it may be rotated to an ineffective position by a crank-pin 10 projecting from a barrel lock 4 or by means of an internal actuator rod 19. In the unlocked condition, inward movement of the rod 9 causes a projection 32 on the rod to abut a projection 25'' on the lever to rock it to the bolt-releasing position, spring 24 then turning the bolt anticlockwise to free the striker from slot 21. The push-rod 9 may be rotated by the key-operated lock, as described, and also by a toothed gear link (not visible) connecting this rod to a rocker 30 operated by internal actuator rod 19. When rotated to its locking position, the projection 32 fails to engage the projection 25"' on the latching lever 25. A cam surface 31 on the rocker 30 engages the arm 25" of the lever 25 to enable the door to be released from the inside even when locked from the outside. If the door is slammed when locked, a plate 28 coupled to the lever 25, rises to abut a pin 27 projecting from the shaft to rotate it to the unlocked condition in which it is capable of displacing the lever 25.
