Title: Improvements on Metal Cutting Machine for Planing and Shaping.
Inventor: RICHARDS GEORGE
Filed: 1900-09-14
Granted: 1901-01-26
Abstract: 16,345. Richards, G. Sept. 14. Planing and shaping. - A shaping-machine is constructed so that it may plane long work in the direction of its length, as well as shape it crosswise. The carriage 2, sliding on a frame 1, has a cross arm 51, on which the tool-box 3 slides so that the work 74 may be shaped crosswise while fixed on tables 24, 25 in front of the machine, or work 75 may be planed lengthwise on tables 23, 25 at the side. The carriage is traversed by a screw 6 driven by two pairs of pulleys and open and crossed belts, which are shifted by a shipper rod 19. The tables 23, 24 are vertically adjustable, the table 25 being bolted to the table 23, which has a receptacle 33 for tools. The feed is obtained from a fixed rack 36, with which gears a pinion 37 on a spindle 38 mounted in a bracket 85 on the carriage. The spindle is connected by a friction coupling 39 and bevel gearing 43 to a spindle 44, driving a shaft 48. The shaft 48 has a collar 57 with a ratchet pawl 58 operating an internally-toothed wheel 59 secured to a wheel 82, gearing with a pinion 79, which, together with a pinion 80, is mounted on a swinging arm 78. This arm may be swung to bring either of the pinions into engagement with a pinion on either of two shafts 76, 77, and thus rotate each of them in either direction to impart a lateral and vertical feed to the tool 5 in the usual way. The amount of the feed is determined by regulating the rotation of the shaft 48 to part of a revolution by means of stops 50, 53, in the path of a pin 49 on the shaft. The stop 50 is fixed, but the stop 53 is carried by a sleeve 52, angularly adjustable by worm gearing 54, and having a dial 55, acting with a pointer 64 to indicate the feed. During the part of the stroke in which the shaft is not rotating, the rotation of the pinion is lost in the friction coupling.

Title: Improvements in and relating to Electric Clocks and Indicating Dial Mechanism for Use in connection therewith.
Inventor: PALMER WILLIAM EDGAR
Filed: 1902-05-07
Granted: 1902-12-18
Abstract: 10,541. Palmer, W. E. May 7. Electric clocks.-A pendulum having a pawl 2 drives a ratchet-wheel 3, and one or more pins 5 on the latter disengage a latch 6 from a lug 10 on a gravity lever 7 pivoted at 8, which accordingly falls and gives an impulse to the pendulum. In so falling, the gravity lever completes the circuit of an electromagnet and is re-set by its lever armature, while distant electromagnets 24 also in the circuit drive indicators. The circuit is made and broken between a platinum-faced rib 16 on the gravity lever and an insulated pin 17 on a flat spring 14, which is normally held in tension by a latch 13, but is set free because a projecting screw 12 on the gravity lever strikes the latch. When the gravity lever is re-set, the rib puts the spring again under the latch. In the indicator shown in Fig. 3, the armature lever 26 rocks a disc 30 and a pawl 33 pivoted to the disc drives a ratchet-wheel 27, each tooth being alternately locked and passed by the notched hub 31 of the disc. In a modification, the pawl is attached to the lever.

Granted: 1903-11-19
Abstract: 28,509. Lake, H. H., [Stone, J. S.]. Dec. 24. Telegraphs.-Wireless-telegraph stations are so arranged that messages can be simultaneously received and transmitted without interference. The transmitting-antenna F, Fig. 1, is associated with the alternator a, key k, coil M, spark gap 8, condensers U, and coil M<1>. The receiving-antennµ V<1>, V<11> are preferably placed half a wave-length apart, and are connected to the oppositely-wound primary coils m of an induction coil M<11>, the secondary of which is associated with the coherer K and relay R. Radiations from the antenna V act equally on the antennae V<1>, V<11>, and produce zero effect on the secondary of the coil M". If the station from which messages are being received is in the plane of the antennae V<1>, V", the effect on the secondary of the received waves is a maximum. The receiving-antenna may be mounted on a frame capable of rotation, so as to receive with maximum efficiency from more than one discant station. Fig. 2 shows a modification, in which balance on the coherer K is obtained by the symmetry of the system with respect to the condensers C", C<111>, and in another modification, divided resistances are placed in the bridge arms c instead of the condensers C", C<111>.

Abstract: 5303. Meakes, J. G. March 6. Lathes; tool-holders. -A machine for turning taper wooden rods, such as puntpoles, tent - poles or billiard cues, has a hollow spindle c mounted in a headstock b and provided at its ends with cutter heads n, q. The stock S is fed through the spindle by feedrollers e journalled in standards f, the lower roller (not shown) being driven by worm gearing h, j, from a pulley shaft k, and the upper one being pressed upon the stock by springs. The stock is guided to the cutter head n by spring guides l, l<1>, the cutters o, p trimming the stock so that it can pass through the spindle c. The stock is finished in size and form by cutters o<1>, p<1> carried by radial slides r, r' on the head q. These slides are pressed outwards by springs 2 and by centrifugal force against inclined rods w carried by a sleeve v, which can be moved axially in the cutter bead q as the work passes through it to give the desired taper to the work by allowing the cutters and their slides to move outwards. The axial movement of the sleeves v is controlled by a yoked lever z<2>, z pivoted at z<3> and carrying a half-nut 3, which can be engaged with a threaded sleeve 4 on the spindle of the lower feed-roller, the sleeve and half-nut being interchangeable with others of different pitches to vary the taper. The feed movement of the half-nut takes place towards the machine so that a tappet 11 adjustable on the lever z can engage a detent 9, to release a spring- actuated lever 5 carrying a pin 8. The upward movement of the pin raises the lever z, disengaging the half-nut 3 and stopping the taper feed. A stop 12 limits the inward movement of the lever arm z. The finished rod passes between rollers m, both cf which are spring-mounted, the lower one being driven by gearing h<1>, j<1>.

Title: Improvements in the Manufacture of Aluminium Sulphate.
Filed: 1903-03-20
Granted: 1904-02-18
Abstract: 6458. Spence, H., and Spence & Sons, P. March 20. Aluminium sulphate. - Crystallized basic aluminium sulphate, containing one molecule of Al2O3 to two molecules of SO3, and easily soluble in water, is obtained by subjecting alumina in excess to the action of hot sulphuric acid under pressure, filtering, evaporating the filtrate, preferably in vacuum vessels, and separating the crystals from the mother liquor. When it is desired to obtain a larger yield of the crystallized sulphate than is possible by this method, the same solution is also treated with finely-divided lime or calcium carbonate under agitation until the desired basicity is obtained. The solution is then quickly filtered and evaporated, as before. If the sulphate contains any considerable proportion of ferrio sulphate, the latter is reduced to the ferrous state, preferably by adding a small proportion of alkali waste, which also precipitates any arsenic present.
