Patent GB-189811186-A (GB)
Title: Improvements in Machines for Tapping Nuts.
Inventor: CARTER JAMES EDWARD
Filed: 1898-05-17
Granted: 1899-04-08
Abstract: 11,186. Carter, J. E., and Wright, S. A. May 17. Tapping.-In a nut-tapping machine, the nuts are contained in a hopper 31, with a sight-hole 31<a>, the bottom nut being fed forward and held by a slide 26 while being tapped by a verticallymovable tap 19. After tapping, the nut falls over the tap and down through a hollow spindle 1. This spindle carries the tap, and is moved vertically at the desired rate by a screw 38 engaging a nut 39 mounted on a spindle. The spindle is rotated by a worm gearing from fast and loose pulleys 9, 10 on a shaft 6, the worm-wheel 2 being mounted in bearings 3 on the frame 5, and feathered to the spindle. A head 1<a> on the spindle slides and rotates in a cylindrical cam-box 20, shown with the cover-plate removed in Fig. 1 and in section in Fig. 3. The box has cam surfaces 20<b>, 20<c> which effect the projection of pairs of spring grippers 13, 14 at the required intervals to hold the tap, the grippers being locked in their operative positions bv collars 22, 23, on vertically-movable rods 22<a>, 23<a>. The screw 38 is driven by the gearing 48, 47, and shaft 44, through either one of the trains 41, 43 or 42, 45, the former giving the spindle a quick downward withdrawal, and the latter a slower upward feed. Either train maybe brought into operation by a clutch 40, and the reversing is effected automatically at each end of the stroke by a lug 53 on the nut 39 engaging adjustable collars 55 on a rod 49 connected to the weighted clutch-operating lever 50. At the commencement, a nut 25 is held by the slide 26 over the tap 19, which is held by the upper pair of grippers 13 only, as shown in the Figures. As the spindle rises, the lower grippers also engage the tap and are locked by the collars 23, and the rods 22<a> are depressed to release the upper grippers, which, when the nut is tapped, spring back above the surfaces 20<b> and allow the nut to fall on to the lower grippers. The screw 38 is then reversed, the upper grippers again engage the tap, and the lower grippers are unlocked by the upward movement of the rods 23<a>, and then retracted, allowing the nut to fall down through the spindle. At the top of the stroke the head engages a spring pin 32, which normally locks the slide 26 carrying the nut, and releases the slide, which is withdrawn by a, spring 29. A bent lever 27, the lower end of which engages the underside of the head, causes the slide to feed forward a nut during the downstroke. A grooved pulley 11 is provided for driving a lubricating-pump. The trains of wheels for operating the screw 38 may be changed for different pitches of taps, and by providing extra operative parts, driven from an extension of the shaft 6, different sizes of nuts maybe simultaneously tapped.

Title: Improvements in or connected with Generators for Acetylene Gas.
Inventor: ROSENTHAL KURT ERDMANN
Filed: 1898-06-24
Granted: 1898-10-08
Abstract: 14,049. Rosenthal, K. E. June 24. Acetylene.-Relates to generators for acetylene gas in which the supply of carbide is automatically regulated by the sinking of the gasometer. The carbide is placed in pipes c leading from a closed chamber b to the water and closed by sliding plates d operated by suitable levers h. A stop f is mounted on a screw e connected by suitable gearing to the gasometer, so that the descent of the latter causes the stop to move along the screw e and engage successively the levers h, thereby allowing the carbide to fall down the pipes c over cones t on to bars s immersed in the water. The latter is fed in through a nozzle p, the waste material being removed through an aperture q. Holes m, v, and n are provided for the gas conduit, the water gauge, aud manometer respectively. When the carbide is used up, the pipes are again closed, and another charge previously placed in the chamber b is scooped into them by means of an arm actuated from the outside by suitable gearing k.

Granted: 1899-01-28
Abstract: 24,568. Fell, J. C., [American Writing Machine Co.]. Nov. 21. Type-writers.-Relates to means for connecting and disconnecting the platen from its line-spacing mechanism, so that the platen may be rotated independently to any extent when desired. To the end of the platen 45 is screwed a cylindrical piece 15, 16 having a central hole for the platen shaft 9. Inside the part 16 turns the flange 36 of the ratchet ring 35, with which the line-spacing pawl 37 cooperates. On a pin 21 on the piece 15, 16 is pivoted one end of a C spring 20, the other end of which is pivoted at 22 to a lever 26 pivoted at 27 in the piece 16. When the spring 20 is extended as shown in Fig. 3, it grips the flange 36 so that the platen and ratchet 35 turn together. The spring may be contracted, as in Fig. 4, to free the ratchet 35 by turning a sleeve 29, on the platen shaft, by means of its knob 19. On the end of the sleeve 29 are lugs 30, 31 which engage the end of the curved lever 26 and move it to contract the spring. The platen, when thus freed, may be turned to any extent independently of the line-spacing ratchet 35 &c.

Title: Improvements in Apparatus for Separating Steam or Vapour from Liquids and Regulating the Discharge of the Latter, more particularly applicable for use in the Manufacture of Sweetmeats.
Inventor: SANDERS CHARLES HENRY
Filed: 1898-12-31
Granted: 1899-11-25
Abstract: 27,637. Sanders, C. H., [Shaw, E.]. Dec. 31. Float valves; tubular valves.-Relates to apparatus primarily intended for separating steam or vapour from hot syrup employed in the manufacture of sweetmeats, and for regulating the discharge of the syrup. The apparatus is, however, applicable generally for separating steam and vapour from liquids and regulating the discharge of the same. Syrup from a closed heating-coil is delivered at 8 into a chamber containing a float 7 and two valves 4 and 5. The valves, which are attached to the float, control respectively the dis. charge of the syrup and the escape of the steam or vapour, and are so arranged that both are not fully open at the same time. When, by the rise of the float, the steam valve is closed, the consequent increased pressure causes a quicker deliveiy of the syrup. The valves may be raised by hand, to enable the apparatus to be emptied and cleaned, by lifting the weighted lever 12 and so bringing a cam finger 11 into engagement with the valve 4. A guide-plate 9 prevents the entering syrup from splashing on the valve 5 and the float 7. The valve 5 preferably consists of a sleeve or socket fitting over a cylindrical projection 3<a> in which lateral ports are formed.

Granted: 1900-12-01
Abstract: 18,712. Thompson, W. P., [Vereinigte Maschinenfabrik Augsburg und Maschinenbaugesellschaft N³rnberg A. G.]. Oct. 19. Elevated railways.-Relates to points and switches for suspension railways. The tongue c is curved on its upper surface to carry the wheel flanges over the main rail a, and is grooved so that the wheels f run on their flanges while they are passing over the thin part of the tongue lying on the main rail. To allow for the rise of the supporting-hook h, the under part e of the main rail is thrown to one side, and replaced by a guide k under the tongue c when the latter is thrown into position. The tongue is connected by a link t to the concentrically-pivoted toothed sector q, which is supported by guide-wheels r and operated through spur and bevel gear from a shaft l.

Patent GB-190101016-A (GB)
Title: Improvements in Dynamo-electric Machines.
Filed: 1901-01-15
Granted: 1901-03-23
Abstract: 1016. British Thomson-Houston Co., [Thomson, E.]. Jan. 15. Converting alternating and direct currents; transformers.-Relates to single-phase alternating-current machines provided with commutators. Such machines may be driven by mechanical power and deliver both alternating and direct currents, or they maybe used to convert alternating into direct current, or conversely. Mechanical power may be taken from the machines as well. The invention consists in preventing sparking in such machines by the use of a commutator in which the segments are crowded together at some portions and more widely spaced at others. Fig. 4 is a diagram of a two-pole " Gramme " machine, in which the reference numeral 13 designates the usual armature winding, 22 the commutator, 20 and 21 the commutator brushes, and 17 the collecting-rings connected to diametrically-opposite points 18, 19 on the armature. Supposing the machine to be converting from direct to alternating currents, it will be seen that, in the position shown in Fig. 4, the electromotive force in the alternating circuit is a minimum, and the machine is consequently absorbing power, or running as a motor. A backward or negative lead of the brushes is therefore required at that moment to ensure sparklessness, and this is practically produced by the method of constructing the commutator, for the coil 14 undergoing commutation is in the neighbourhead of the trailing pole corner. When the axis 18, 19 is across the magnetic field, the machine is acting as a generator, and in that case also the requisite lead-now a forward one-is obtained. At an intermediate position the lead is zero.
