Title: Gear selector mechanism
Inventor: LANZENBERGER H
IPC: F16H63/38
Filed: 1973-02-12
Abstract: 1369419 Change-speed control FRIEDRICH DECKEL AG 12 Feb 1973 [11 Feb 1972] 6863/73 Heading F2D A gear shift mechanism comprises a rotatable selector plate, at least one lever for moving sliding gear-wheels and rotatable in a plane substantially normal to the axis of rotation of the plate, at least one conical socket on the lever or the plate, and a group of pins on the plate or the lever for co-operation with the conical socket(s) so that a change of ratio is effected by axial movement of the plate to disengage a pin from a socket, followed by rotary movement of the plate to select a desired ratio, and axial movement of the plate to engage a pin with a socket, the conical formation of the socket having a self-aligning action with the pin so that the leveris repositioned to establish the desired ratio. As shown, the selector plate 1 may be lifted against a spring 14 by a milled head 13 to withdraw a pin 2 from a socket 5 carried by a lever 6 pivoted at 7, and a pin 3 from a socket 8 carried by a cranked lever 9 pivoted at 10. The plate may then be turned to any of nine positions, indicated by a dial plate 22 and located by a pin 21 coacting with holes 20, and pressed downwardly, assisted by the spring 14, to cause other pins to engage the sockets and cause angular movement of one or both of the levers. Nine pins 3 are arranged in an outer group on three concentric circles, and nine pins 2 are arranged in an inner group on three concentric circles. The width of the mouth of each socket is at least twice the difference between the radius of the largest and smallest circle on which its associated pins are arranged, and as the relative movement between pins and sockets is substantially radial relatively to the plate 1, parts of the conical surfaces of the sockets are unnecessary and may be cut away, as shown on the socket 5. In a modification, each lever is connected for rotation with an element situated above a casing part 40 and carrying three upstanding pins for co-operation with downwardly facing sockets on the plate 1. Also described is a mechanism comprising a rack connected by a pinion and a one-way clutch to one of the gearwheels and operative to turn that wheel as the selector plate is lowered to facilitate gear engagement.

Title: Stepped pulley drive
IPC: F16H7/08
Filed: 1927-03-11
Abstract: 267,550. Maschinenfabrik Oerlikon, (Assignees of Hildebrandt, J.), March 11. 1926, [Convention date]. Variable-speed belt gearing; gearing for stopping and starting machinery.-In stepped-pulley gearing, a tension-pulley 7 for the belt 3 is carried in a fork turning about a rod 6 and is pressed against the belt by a weighted chain 8 passing over a sprocket 9 loose on a rod 13. The sprocket 9 is integral with a clutch disc 12, a clutch roller 16 pressed by a spring 18 jamming between the disc and an arm 15 on a sleeve loose on the rod 13 and secured to a worm-wheel 14 engaged by a worm 19 on a shaft 20 rotatable by a crank 21. During drive, the roller 16 bears upon an adjustable stop 17 so that it is disengaged from the parts 12, 15 against the action of its spring 18 and the weight acts freely upon the pulley 7. On rotating the arm 15 in the direction of the arrow, the clutch roller 16 becomes operative and the sprocket 9 is rotated to remove the pull on the pulley 7, so that the drive ceases. The fork 11 is adjustable laterally so that the belt is properly positioned by a guide 33 on the fork and a guide 23 on a frame 22 which slides on the rods 6. 13 and carries the whole of the belt-tensioning means. The frame 22 is moved to shift the belt upon the stepped pulley 2 by a crank 27 turning in the main frame and carrying a pin 25 engaging a slot 26 in the frame 22. When the belt 3 is loose, the pressure of the roller 16 causes sufficient friction between the disc 12 and rod 13 to prevent sliding of the frame 22, and when the belt is tight, similar friction may be produced by pressing the arm 15 on the frame.

IPC: E04F15/20
Filed: 1935-03-06
Abstract: 453,059. Securing battens &c. to floors, roofs, and walls. KAHN, C., 35, Ferncroft Avenue, Hampstead, London. March 6, 1935, No. 7023. [Class 20 (iv)] A clip for securing fillets or battens to concrete and other floors, roofs, and walls comprises a metal base 1 for attachment to, or embedding in, the structure and a metal member 5 adapted to be secured to the fillets or battens, these two members 1, 5 being secured to the opposite surfaces of an intermediate member 3 of soundinsulating material, such as asbestos, by rivet or like members which pass through the intermediate member 3 and have their ends countersunk in such member so that there is no soundconducting contact between the said metal members 1, 5. Each rivet or like member is countersunk in the opposite face of the intermediate member 3 to that on which is located the metal member 1, 5 secured by the said rivet or like member. The base 1, Fig. 2, is U-shaped and is secured to the intermediate member 3 by rivets 4 having their heads countersunk in the upper surface of such member. The legs of the base 1 have punched-out projections 1<1> to provide anchorage in a concrete structure. The member 5 is in the form of two ears bent from a metal strip which is anchored to the intermediate member 3 by a central rivet 7 having its head countersunk in the lower surface of such intermediate member. Prior to use, the ears 5 are bent over in overlapping relation and are each formed with a transverse shoulder to facilitate bending into a vertical plane. The base 1 shown in Fig. 4 is formed from a single metal strip which is doubled on itself and has its ends 8 bent outwardly. The doubled portion has tongues or barbs 10 bent therefrom to anchor the device in a concrete structure or in a joint of a brick or block wall. In another form, the base is in the form of a flat strip as shown in Fig. 5 having its ends extending beyond the ends of the intermediate member and provided with holes for nails, screws or bolts for attachment to a brick or block wall or to a wood joist or other support. The ears may be formed from separate members which are connected by an interposed metal strip by welding or other means. The attachment of the metal member 5 by means of a single rivet provides a pivotal mounting whereby the member may be turned to the correct position to receive the fillet or batten. When desired, the member 5 may be secured by two rivets. If desired, the member 5 and the base 1 may each be provided with projections adapted to extend through the intermediate member and welded to disc or other metal members which are countersunk in the opposite face of the intermediate member to that on which the corresponding member 1 or base 5 is located. The clip may be formed with one ear only.

Title: Electronic timepiece
IPC: G04G5/02
Filed: 1976-02-23
Abstract: 1509862 Electronic timepieces DAINI SEIKOSHA KK 23 Feb 1976 [4 March 1975]  07036/76 Heading G3T [Also in Division H1] An electronic timepiece (e.g. a wristwatch) including an oscillator circuit 101, Fig. 2, followed by a frequency divider 102, driver circuit 103, and a reversible stepping motor 104 coupled to a time display 108 (e.g. using hands) via gear trains, has setting switches S 1  and S 2  for advancing and retarding respectively the time indication and at a rapid or slow rate depending upon the length of time a respective switch is maintained closed. Circuits 110A, 110B determine whether a respective switch has been closed for more than 0À5 secs. For example, if S 1  is held closed for less than 0À5 secs, circuit 110A output causes a pulse generator 112 to add one pulse to a train of alternate positive and negative pulses which are received by the driver circuit 103 from the divider during normal operation of the timepiece. Likewise if S 2  is held closed for less than 0À5 secs, a control signal from 110B causes an output from generator 112, which closes a gate in driver 103 so as to block one drive pulse. Thereby the time indication is advanced or retarded by 1 sec. If S 1  is held closed for more than 0À5 secs a control signal F from circuit 110A causes a pulse generator 111 to send an additional pulse train Fig. 3B (not shown) to the driver circuit 103 which pulse train is at a higher frequency than the normal pulse train, Fig. 3A (not shown). Similarly, when S 2  is held closed for more than 0À5 secs a control signal R causes a higher than normal frequency pulse train, Fig. 3C (not shown) to be applied to the driver circuit, the first pulse of this train being of longer duration than the subsequent pulses so as to cause reverse rotation of the motor 104. Thereby rapid advance or retard of the time indication is effected. As shown Figs. 4, 5, the switches Si, S 2  are constituted by a stem 122 having a radial projection 123 engageable with either one of a pair of fixed contacts 127 depending upon the direction in which the stem is rotated. A spring member 124 acts to return the stem to its median position. However, if the stem is rotated through an angle # 2 so that its projection 123 rides over a U-shaped portion of a contact 127, the projection and contact will remain engaged until the stem is manually returned whereby closure of a switch for more than 0À5 secs can be effected. For brief closure of a switch the stem is rotated only through an angle # 1 .

Patent GB-979228-A (GB)
Title: Method and apparatus for producing and packaging glass fiber strand
IPC: D02G3/18
Filed: 1963-02-22
Abstract: Glass fibres 16 are gathered into a strand 20 which passes over a constant speed capstan 24, or other constant speed pulling means, serving to attenuate the fibres and the strand 20 is then wound on to a forming tube 38 at a tension substantially lower than that used to attenuate the fibres.  The motor 40 used to drive the forming tube 38 may be a constant torque high slip induction motor or a constant horse-power high slip induction motor.  In the latter case the strand is wound on to the package at constant tension while in the former case the tension decreases with growth of the package. The tension preferably lies in the range of 30 to 200 grams and particular values may be selected by varying the voltage applied to the motor 40.  The capstan 24 is driven at constant speed, e.g. by a synchronous motor 26, and is provided with a dancer pulley 28 to take up slack and to ensure gripping contact of the strand with the capstan.  In an alternative arrangement (Fig. 2, not shown), the winding means are mounted above the pulling means and no dancer pulley is required.  A conventional traverse 36 is provided and the motor 40, <PICT:0979228/C1/1> collet 34 and forming tube 38 may be reciprocated to form a package of desired shape, e.g. having successive cylindrical layers of decreasing length.  Size is applied to the fibres 16 by means of a suitable applicator 18.  Specification 585,094 is referred to.
