IPC: B23B11/00
Filed: 1935-05-23
Abstract: 439,351. Making nuts and bolts; lathes. HAHN, H., HAHN, O., and TESSKY, K., (trading as INDEX-WERKE HAHN & KOLB), Esslingen-on-Necker, Germany. May 23, 1935, No. 15002. Convention date, May 28, 1934. [Classes 83 (ii) and 83 (iii)] Combined turning, boring, and screwing.- An automatic lathe has a gripper-arm for conveying cut-off workpieces to two or more further working positions in which the disengagement of the arm from a stop that determines its position is derived from the working movements of the gripper. A nutblank 10, Fig. 3, is cut-off at 1 and engaged by the rotatable and axially-movable gripperarm 3 which, in conjunction with the guide rails 18, 21 and positioning device 24, carries the blank to the countersinking position I, Fig. 1. The gripper engages a stop 5 in this position, the latter being slidable axially and urged outwardly by a spring 8, Fig. 4, as the gripper is moved inwardly for the countersinking operation the stop is also similarly moved and a spring-pressed latch 15 pivoted at 13 finally engages a projection at the side of the stop and holds it so that when the gripper is moved away from the countersinking tool it is free from the stop 5 and may be moved to the next position II where the nut is fed on to a revolving tap 16, Fig. 3, in this position a plunger 17, Fig. 4, is depressed by the gripper which releases the stop 5 which is re-set for the next set of operations on a nutblank. Further working positions may be provided and instead of the countersink a slotting saw may be employed : the invention is also applicable to making screw-bolts.

Abstract: 895,173. Mixing appliances; proportionate feeding. TARUKAWA, T. May 12, 1958 [May 13, 1957], No. 15098/58. Class 86. [Also in Group XVIII] In an electrically controlled mixing apparatus for mixing predetermined weights or measured quantities of liquid and/or powdery stock materials, and delivering the mixture, in automatically repeated cycles (see Group XVIII), the stock materials are automatically fed to each measuring tank or weigh bin 1, 2, 3 until it contains the desired quantity whereupon an associated switch device S1, S2 is operated to effect closing of a further switch S3 (or S4 or S5) which controls the discharge mechanism of the tank, the respective switches S3, S4, S5 being connected in series whereby discharge of the tanks or bins 1, 2, 3 into the mixer 9 is simultaneous and takes place only when all the bins or tanks are correctly filled. After sufficient time for complete discharge from the bins or tanks, the respective discharge openings are closed and material feed, which had previously been automatically cut off, restarted. The mixer 9 shown is of the rotary drum type with a discharge shoot 10 which is electrically controlled so that sufficient mixing time is provided before discharge, and so that the bins or tanks 1-3 cannot feed into the mixer whilst the shoot 10 is in discharge position. The mixer may also be of the kneading type, the drum being stationary during mixing and rotatable through 180 degrees for discharge.

Title: Improvements relating to electrical time base circuits and the like
Inventor: NAGY PAUL
IPC: H03K4/22
Filed: 1950-06-16
Abstract: 679,294. Saw-tooth generating circuits. NAGARD, Ltd. Jan. 31, 1951 [June 16, 1950], No. 15125/50. Class 40 (vi). In a saw-tooth generator of the Millertransitron type a rectifier is connected to the screen grid to maintain it at a constant potential during the sweep in order to prevent non- linearity due to changes in screen grid voltage caused by unwanted components of the triggering signal fed to the screen or suppressor grids. As shown, the rectifier D is connected between the screen grid and one of the positive potential points 3a, 3b and thus limits the screen potential to a steady value somewhat less than normal. The potential may, however, drop to the low value required during the fly-back. A further rectifier DS similarly limits the suppressor potential. Synchronizing signals are fed from the anode of a limiter valve V to the screen grid and the circuit may be converted to a single stroke type by operating switches B<SP>1</SP>, B2 and B3 which connect the suppressor to a negative potential, the rectifier D to a lower positive potential and suitably adjust the cathode bias of the limiter valve V. The switch B2 may, however, be omitted if the screen resistor R3 is used also as the anode resistor of valve V (Fig. 4, not shown).

Title: Improvements in nailing machines
IPC: B27F7/13
Filed: 1925-10-29
Abstract: 257,555. Lamb, A. Oct. 29, 1925. Loose-nailing. - A nail separating and delivering device comprises a plate 37 mounted on a transversely reciprocating bar 32 and arranged at the foot of the usual nail chutes 15. Recesses 38, Fig. 2, in the plate 37 normally coincide with the ends of the chutes and receive the end nails. The bar 32 is normally held in a. position to allow this by a spring 53, but is moved to the right to transfer the nails in the recesses 38 to the tubes 33, by a rod 51 and bell-crank lever 52 acting through the intermediary of springs 35. This yielding operation prevents damage by misplaced nails. The lever 52 is operated by a tappet 54 on the driver bar 5 at each reciprocation of the latter. To prevent a second reciprocation of the separator 37 until the nails already fed to the nail chucks have been driven, the bell-crank lever 52 is held in its raised position by a catch-lever 55 until the latter is released by a stud 58 as the driver bar 5 is completing its driving stroke. An alternative means for operating the selecting bar and preventing double feeding is shown in Fig. 4. As a hammer bar 5<1> moves nearly to the top of its stroke, a tappet 54<1> strikes a lever 20 so that a forked end 21 moves a sleeve 22 and a selector bar 37<1> through springs 35<1>, to the left. As the bar 5<1> descends, the selector mechanism, being balanced, does not move until a stop 24 engages a hooked link moving the mechanism to the right. Specification 257,385 is referred to.

Title: Improvements relating to rotary printing and numbering machines
IPC: B41F33/04
Filed: 1939-05-24
Abstract: 529,182. Printing-machines. HALLEY & SONS, Ltd., J., and HALLEY, A. M. May 24, 1939, No. 15357. [Class 100 (ii)]  In a rotary printing or numbering machine in which the printing operations are controlled by sheet detector mechanism the detector mechanism acts to trip the printing or numbering cylinder if a sheet is not fed, and the printing cylinder remains out of operation until the sheet feed is restored and then comes into operation automatically. The printing or numbering cylinder 9, Fig. 1, is mounted in pivoted frames 6a connected by a connecting-rod 10 to a lever 11 fitted with a roller 11a resting on a disc 13 formed with a recess 13a. The roller 11a normally rests in the recess 13a and the roller 9 is in printing- position. If however a sheet is not fed to the machine the disc 13 is rotated to move the recess 13a out of register with the roller lift and the roller 9 is moved out of printing position. The disc 13 is rotated by a pawl 16 operated by an oscillating lever 20, the pawl being adapted to engage a pin 13c on the disc 13 when a lever 18 is moved from full line position to the dotted line position by the action of the sheet detector mechanism. The pawl 16 is controlled by stops to be set to engage either the pin 13c or pin 13b, and after it has acted on pin 13c to trip the impression it remains in this position until the resumption of sheet feed moves the pawl to engage the pin 13b and return the disc 13 to the position shown. The pawl then oscillates idly as long as the sheets continue to be fed. The form of the pawl 16 and its operating lever may be modified. The detector mechanism for operating the shaft 19 of the lever 18 is shown in Fig. 4 and comprises a latch member 25 which can engage a fixed bar 26 when no sheet is fed to the impression cylinder 15, but is freed from the bar 26 when a sheet is fed. In the latter case motion is given to the shaft 19 by a pivoted rod 33 carried by a lever 34 oscillated by a cam 30. The rod 30 engages a rod 37 secured to a lever arm 19a on the shaft 19, the rod 37 being controlled by guides 38. If a sheet is fed correctly the latch 25 does not engage the bar 26 and a roller 29d on a lever 29 can follow a cam 30 and so cause a bar 31 to move the rod 33 out of the path of the rod 37, and no actuation of the lever arm 19a takes place.

Title: Improvements in or relating to Phonographs
Inventor: CASTAGNA JOHN FRANK
IPC: G11B3/00
Filed: 1968-04-02
Abstract: 1,166,582. Disc record players. J. F. CASTAGNA. 2 April, 1968 [5 April, 1967], No. 15723/68. Heading G5R. The record player comprises in combination a sound-reproducing cone fixed in position, a needle, and a mechanical linkage, including successive sections interconnected by highlycompliant articulated portions, directly connecting the cone with the needle, whereby the cone is directly responsive to needle movements. As shown, a needle N is secured in a horizontal portion H of a linkage L which takes the form of a one-piece member moulded of polypropylene. The portion H has two integral hinges 53, 59, which lie along its longitudinal axis AA. The hinges are formed by sections, e.g. 51, 52, of V-shaped cross-section whose apex edges coincide to form the hinge line, e.g. 53. Hinge section 51 is cemented to a resilient pad 54, which in turn is cemented to the underside of a tone arm 15; an arm portion 62 extending upwardly from hinge section 58 is inserted in a pocket 28 in arm 15. Thus, the portion H is rocked about its axis by the needle N as it responds to the record groove modulations. This horizontal rocking movement is converted, by a hinge 70, Figs. 4 and 5, to vertical reciprocating movement of a vertical portion V of the linkage L. The tone arm 15 is supported by bearing ears 36A at the top of a yoke member 35, which also has a bushing 38, 39 which swivels in a bearing portion 41 integral with the phonograph deck 12 to provide horizontal movement. The vertical portion V includes an offset portion 77 which extends through an opening 40 in the yoke and bushing and is secured by a wedge 79 in the bushing 33 of a sound reproducing cone C. Thus, the cone C is directly responsive to movements of the needle N. The sound is emitted from the phonograph casing through perforations 18 in deck 12. Hinge 70, which lies in axis CC, is laterally offset from axis AA by an amount which may be pre-selected. The volume output of the cone C is directly proportional, while the compliancy of the linkage is inversely proportional, to the amount of offset. Vertical movement of tone arm 15 is permitted by another integral hinge 66, and horizontal movement by a further integral hinge 74. By alignment of hinges 53 and 59 along axis AA, the inertia of body portion 46 of portion H is minimized. This in turn, together with the high compliance of all the articulated portions of the linkage L, ensures minimum wear of the record grooves. The phonograph is suitable for incorporation in toys, e.g. talking dolls.

Abstract: 102,487. Kubel, S. J. Nov. 27, 1915, [Convention date]. Sheet-registering devices. - A sheet gauge or stop is adjusted step by step in either direction by electro-magnetic mechanism controlled by switches arranged either adjacent to, or remote from, the gauge. As shown, the device comprises ratchet-wheels 20, 21 on a shaft 12, which is screw-threaded to engage a plate 14 connected to the gauge 16 by pins 15, The ratchet-wheel 20 is operated by a dog 29 on an arm 27<1>, which is formed on the armature 27 of a solenoid 25 and is loosely connected to the armature 28 of a solenoid 26, a spring normally holding the arm away from the armature 28. On energizing the solenoids 25, 26, the arm 27 is attracted to the armature 28, thus bringing the dog 29 into engagement, and the armatures rise and cause the ratchet-wheel to turn through one tooth each time the solenoids are energized. The ratchet-wheel 21 is operated in the opposite direction to the ratchet-wheel 20 by devices similar to those described above, comprising a dog 29<1> on an arm 27<11>, which is formed on the armature 27<a> of a solenoid 26a and is connected to the armature 28<a> of a solenoid 25<a>. The gauge is held in the set position by means of a detent 37, which can engage holes 22 in a collar on the shaft 12, the detent being formed on the armature of a solenoid 35. The solenoids of each gauge are arranged in the circuits shown in Fig. 9, the pairs 25, 26 and 25<a>, 26<a> being controlled respectively by push-buttons pa, pb on the gaugesupport or by push-buttons p, p<1> arranged at a distant point, such as the delivery end of a printing-press. The distant push-buttons of all the gauges employed may be arranged in a block. The gauge-support consists of an arm 1 which is provided with a bracket 11 for supporting the solenoids. As applied to the side and front stops of a printing-press, the arms 1 of the side stop may be adjustably secured to the feed-board, and the arms 1 of the front stops may be adjustably secured to brackets on the usual rock-shaft, screws being provided for coarse adjustment.
