Title: Change speed gearing for motor vehicles
IPC: F16H3/08
Filed: 1929-04-29
Abstract: 333,201. Seidel, A. April 29, 1929. Variable-speed gearing for vehicles comprises an over.driving train of gears 7, 9, 10, 8 which is moved bodily along with a clutch sleeve 3 to change between direct and over drives, and may be used as a self-contained unit, as shown in Fig. 1, for use in series with a change-speed gear, or may be incorporated in a countershaft changespeed gear, as shown in Fig. 7. The two-speed gear shown in Fig. 1 is in position for yielding direct drive, the clutch teeth 5 on sleeve 3 engageing like teeth 6 on the end of the driving-shaft 1. Helical silent gearing is preferably used. The sleeve 3 drives shaft 2 to which it is splined, and the toothed gearing is at rest. Gears 9, 10 are loose on countershaft 11. To change to overdrive, rod 21 is moved to the right of Fig. 1 and upwards of Fig. 3, whereby a female cone surface 19<1> within gear 7 engages a cone surface 19 on sleeve 3. The gearing is thus set rotating, whereby clutch teeth 16 within gear 7 are enabled to engage outwardly-projecting clutch teeth 6, and also clutch teeth 4<1> within gear 8 are enabled to engage rotating clutch teeth 4 on shaft 2, which is thus accelerated. In Fig. 3, 21<1>, 21<2> arethe control rods for the main change-speed gear, and 12 is a gate in which works a control lever. In order to reach position S for the overdrive, the control lever must pass from position D1, the direct drive in the main gearing, to position D2, the direct drive for the auxiliary gearing. Positions L are neutral. The form of clutch teeth is best shown in Fig. 7; the inclined ends of the faster-running teeth 5 ratchet over the slowerrunning teeth 6 until engagement is possible. The overdrive is passed through a clutch 4<1>, 4. Reduced and reversed drives are obtained through the gears 87, 88, 97, 101 and an idler (not shown). A form of incorporated gear is described in which the gears of the overdriving train are long enough to allow the countershaft gears 9, 10 not to slide, while the clutch gears 7, 8 and sleeve 3 slide relatively to them.

Title: Recording and playback arm operating and setting means for dictating machines
Inventor: JR ANTHONY CHARLES DENAPOLI
IPC: G11B3/06
Filed: 1956-05-03
Abstract: 800,700. Dictating-machines. SOUNDSCRIBER CORPORATION. May 3, 1956, No. 13723/56. Class 40 (2). A dictating-machine employing disc records is provided with recording and playback heads 49, 48, respectively, on arms 47, 46 traversible in opposite directions inwardly across the record D by a power drive, and with means for simultaneously lifting and retracting said arms to the outer zone of the record operated by lifting a part 29 of the casing 28 overlying the heads and record disc. The arms 46, 47 carrying the heads hinge about flat hinge-springs 56, Figs. 3 and 4, mounted on hubs 52, 53, Fig. 12, frictionally coupled to shafts 61, 62 rotated by means of a worm 67 and wheels 63, 64. During the first part of the lifting of flap 29 the heads are lifted from the record by a bar 120 engaging lugs 134, 135 on the arms 46, 47, the bar 120 being lifted by means of lugs 128, Fig. 11, which engage the ends 130 of levers 121 carrying bar 120. Further opening movement of flap 29 causes the heads to be swung outwardly, ready for record changing, through the medium of a link 94 and a bell-crank 99 coupled to the hubs 52, 53 via links 104, 103, respectively, whereby the hubs are rotated on the shafts 61, 62 against the friction coupling thereon to the positions shown in Fig. 4. The links 103, 104 are slotted as at 105, 107 to provide lost motion so that the flap may be closed without interfering with the positions of the heads which are then free to traverse inwardly. The relative positions of the heads when lowered are such that the play-back head is placed at a slightly greater radius from the record centre and therefore trails somewhat behind the recording head and may, therefore, monitor the recording. In the event of it being decided by an operator to defer playing back, the play-back head may be lifted by handle 140 and swung back against the friction drive to engage a latching element 142 from which it may be released by pressure on a thumb-piece 151. Similarly the handle may be used for back-spacing the head at any time it is required to repeat a reproduced passage. The recording head may be held to suspend a recording by operation of a control 160, Fig. 3, which lifts the head by means of a slotted arcuate spring-plate 157 and holds it against the traversing friction drive by means of a plunger 153, Fig. 16.

Title: Improvements relating to the manufacture of spiral metal pipes
IPC: B21C37/12
Filed: 1927-05-23
Abstract: 284,518. Freeze, J. R. May 23, 1927. Pipes.-In making sheet-metal pipes by feeding a metal strip, converting it into helical form and continuously welding the abutting edges thereof, the coiling is effected on a roll or mandrel by members disposed on each side thereof. The pipe is formed by forcing a strip A by feed rolls 82, 30 driven by a worm gear 26, 27 and spur gear from a motor 22, along a table 24 with curved guides 25 and between an idle roll 9 and a pair of fixed rods, or driven or idle rolls 4, 5, and thereupon butt-welding the seam between the adjacent edges of the unbent and bent portions of the strip by an arc welder 18 arranged over the end of the roll 9. The rolls 4, 5, 9 are mounted in standards 2, 3 on the base 1. The roll 9 passes through a slot 6 in the standard 2 and is supported at one end on a pair of rollers 14 carried by a screw-adjusted block and at the other end in a journal adjustable by a screw 10 in the standard 3. The roll 9 may thus be adjusted to suit the diameter of the pipe. In order to vary the pitch of the helix, the feed rolls and their driving mechanism and the table 24 are mounted on a base 21, which is angularly adjustable about a pivot 1a in vertical alignment with the welding point. In order to obtain pipes of any length, a second strip may be butt welded to the rear end of the first strip during formation of the pipe. For this purpose a T-bar 40 arranged at an angle to the line of feed serves as a guide for an arc welding head 41. The ends of the strips are secured together in butted relation by a clamp 44 which has a cross bar 45 resting on the strip A. When this bar engages a roller 43 on the head 41, the latter is traversed along the bar 40 so as to weld the strips together.
