Abstract: 863,918. Spindle retaining means. KEYSER, J.J. Dec. 9, 1958 [July 7, 1958], No. 39579/58. Class 120(2) Holding-down means for a spinning or twisting spindle comprises two members, one rigid and the other a flexible annular disc, both members being housed within either the spindle top or the fixed base in such manner that the spindle top may be secured or released by an exclusively axial motion. The flexible member is preferably supported on one side against a shoulder and the rigid member shaped so that withdrawal of the spindle top requires a greater force than its replacement. In Fig. 1, a groove 9 in the spindle base 3 carries the disc 10 which cooperates with a lip 7 on the whorl 2 of the spindle top. In Fig. 3 the base 3 carries the disc 17 above a neck bearing 4 and a frusto-conical part 14 of the spindle top forms the rigid member. In Fig. 5 the disc 21 is mounted between two rigid discs 22, 23 on the base 3 and co-operates with the part 20 of the spindle top positioned above a footstep bearing 5. In all embodiments the disc may be mounted on the spindle top and the rigid member on the base. The members may serve as sealing or guard elements to prevent penetration of dust or discharge of lubricant.

Abstract: 339,815. Singer Mannfacturing Co., Ltd., Rickey, W. J., and Tivendale, W. Dec. 30, 1929. Straightening ; working at specified temperatures. - In straightening sewing machine and other needles by hammering, the needles are heated preparatory to or during the hammering operation in order to reduce liability to breakage. The needles may be fed in succession to a number of hammers 4 from a hopper by a pair of oppositely rotated screws 1, 2 and between a vertical rest and a spring-mounted pressure bar 22 provided with a face of rubber or other frictional material to ensure rotation of the needles during traverse. In the path of the needles is arranged a square casing 6 of metal such as copper which may be chromium-plated, over which the needles roll. This casing contains a cartridge 7 enclosing a resistance wire connected to a source of current through a rheostat. The temperature of the heater may be between 300‹ F. and 700‹ F. A recess 12 in the upper face prevents overheating of the needle points. The casing is adjustable by screws and slots in a carrier 14, which may be moved transversely by a push-rod 15 to place the heater out of action when the machine is stopped. The operative position is determined by a spring-detent 18 and notch 19. In another form, the needles may be fed from a hopper 24 to a single hammering station 25' by a reciprocating slide 25, an electric heater 7 with a copper cap 7' being mounted beneath the hopper and being raised and lowered by a hand lever 33. The needles are rotated during hammering by a friction disc 26. The feeding and/or the straightening operations may be effected manually. In one form, the needles may be fed by a pair of screws over the heater and then over a rubberfaced anvil on which the operator straightens the needles by a hand hammer after stopping the feed. The anvil may be of steel and may contain the beating cartridge. Specifications 28625/10, 26094/11 and 26096/11 are referred to.

Title: Circuit arrangements
IPC: F02P5/15
Filed: 1974-09-13
Abstract: 1479467 Counting apparatus ROBERT BOSCH GmbH 13 Sept 1974 [14 Sept 1973] 39936/74 Heading G4D [Also in Division F1] A digital circuit arrangement is provided for initiating an operation, ignition or fuel injection or valve operation, in an I.C. engine at an angular position of the crank-shaft determined by the operating parameters of the engine. The arrangement shown includes a pulse tachogenerator 10 for producing a train of pulses, a periodic time counter 27 for determining the periodic time of the tachogenerator pulses, a final state memory 28 for storing as a binary number this periodic time, a characteristic curve pulse generator 30 for producing a train of pulses which are non-uniformly distributed over the angular distance traversed by the crank-shaft and a counter 35 for counting these pulses, so that an initiating output signal is obtained from comparator 39 when the count in counter 35 is the same as that in memory 28. The output from pulse tachogenerator 10 which produces narrow pulses is used to control the transfer of data from counter 27 to the memory 28 and presetting data from memory 41 into counter 27. The oscillator 26 produces pulses whose frequency varies with the induction manifold pressure as detected by bellows 20 which alter the position of core 23 in coil 24. The presetting data is stored in read only memory 41 which is addressed by lines 43 which may signal conditions of engine start by switch 48 and/or the output of an exhaust gas probe (switch 49). The desired value is derived from tachogenerator 30 which consists of a wheel rotating with the engine crank-shaft and having unevenly spaced teeth around its periphery for co-operating with pick-up coil 33. The arrangement of teeth is such as to provide the desired ignition advance/time period characteristic. A crank-shaft driven switch 36 is provided to reset the counter 35 and load it with a presetting count from memory 42 which is similar to memory 41 and, as shown, is addressed at input 44 by a signal responsive to engine temperature as detected by NTC resistor 47. Preferably the wheels 11, 31 and switch 36 are replaced by an optical tachometer arrangement including marks scribed in tracks around a disc and read photoelectrically. The reference pulse from switch 36 is arranged to occur at 42‹ BTDC so that counter 35 starts to fill at 40‹ BTDC and provision is made by extending the marks for the ignition to be retarded to a position after TDC under extreme cold conditions.

Abstract: 1,178,228. Winding mandrels. E. W. BLISS CO. 23 Aug., 1968 [18 Oct., 1967], No. 40385/68. Heading F2U. An expanding winding mandrel has segments 50, Fig. 4, expandable outwardly relative to a fixed portion 14, Fig. 1, and sheet material securing means which comprise a stationary gripper jaw 86 in one segment, a rotatable gripper jaw 92 in the same segment and operating means, connected between the non-movable portion and the rotatable gripper jaw, automatically rotating the gripper jaw in a clamping direction when the segment is expanded outwardly. When rod 32, Fig. 1, is moved axially by a mechanism (not described) a spider member secured thereto and engaged at its radial ends with outer wedge bars 26 moves the latter axially along inner wedge bars 18 so that the engagement of ramps 24, 28 causes the outer wedge bars 26 to move radially inwardly or outwardly. The outer wedge bars 26 have inclined surfaces (30), Fig. 3 (not shown), which engage corresponding surfaces (50) of spring-loaded segments (48) and 50 which thereby move inwardly or outwardly with the outer wedge bars 26. Each segment 50 has the hardened stationary gripper jaw 86 in an insert 84 and a further insert 88 mounting the rotatable gripper member 92 having a shaft portion 94 and a jaw portion 96. The shaft portion 94 has at its left-hand end in Fig. 1, a crank 118 which engages by a pin 120 in the end of a spring-loaded operating member 112. The latter has a shaft 106 which passes through a block 104 secured by a pin 102 to an end plate 74 secured to the non-movable portion 14. Thus as the segment 50 is moved outwardly the operating mechanism tends to maintain a fixed distance between pins 120 and 102 causing the gripper member 92 to rotate to grip the sheet material 98, any slight differences in material thickness being accommodated by the compression of spring 124. Another segment 50 may have a similar gripper mechanism which is orientated to grip material for winding in the opposite direction of rotation. The right-hand end of shaft portion 94 is fixed to a cam (130), Fig. 8 (not shown), whereby the gripper jaws can be levered free .should they become jammed on the sheet material.

When bobbin changing is initiated, a suction head 2 is moved by parallel linkage 11, 12 on to the bottom bobbin in the magazine to draw off the tip bunch. As the transfer hammer inserts the bobbin into the shuttle, a striker 116 on the hammer depresses a jaw 108 into contact with a spring jaw 109 to grip the weft; a flap on the jaw 108 closes the suction mouth to prevent any further weft from being drawn in. A continuation of the jaw 108 on the opposite side of its pivot 106 comes above a latch 113, which snaps under it to hold the jaws closed after the suction head has returned to the right. If the tension on the weft becomes excessive, the spring jaw 109 permits some weft to be drawn out of the suction head. On the next beat-up movement, a striker 117 on the slay disengages the latch 113 to allow a torsion spring 111 to open the jaws. When the temple cutter operates, the tip bunch is disposed of through the suction pipe 3.
