Title: Improvements in Apparatus for use in the Manufacture of Turbine Wheels, Rings or Drums.
Inventor: FERRANTI SEBASTIAN ZIANI DE
Filed: 1903-07-09
Granted: 1904-10-08
Abstract: 15,186. Ferranti, S. Z. de. July 9. Welding; working by electricity; boring and drilling; work - holders; tools.-In a machine for electrically welding turbine blades on to a wheel, ring, or drum a, and for slotting, drilling, or otherwise preparing the wheel a as described in Specification No. 11,921, A.D. 1903, the copper blade-holder c is gripped in the copper-capped bearing d of, and is locked by a wedge e at the proper inclination on, a crosshead f, which is reciprocated by the toggles n, o and the spring m on the slide h, the bottom of which is inclined to facilitate vertical adjustment. The carriage k is reciprocated on the box 13 by a rod 23 and a crank 22 which is alternately rotated half a turn in opposite directions by chain gearing 20, 19, 18, a worm 16, and a clutch arrangement on the main shaft 25. The slotting or other attachment 33 is secured to the bed 14, one or two stepped serrated cutters being used so as to complete a slot each time it is lowered by the screw 36 and the gearing 38, the work being steadied by a clamp on the pillar 33. The work a is intermittently rotated on the adjustable support 49 by gearing 46, 47, a ratchet-wheel and pawl 45, and two tappets 42 on a rod 41. At the end of the return stroke of the carriage k, the stops 30, 4 engage the rod 28 and the bell-crank lever 3, and move the arm 29 of the toggle o into a position to be locked by the trip lever 31, and the switch w into its " on " position, and the catch 2 into a position to be locked by the trip lever t. The carriage k is then moved forward into contact with spring buffers which take up any backlash and to bring the blade into contact with the wheel a. The crank 22 then lifts the trip lever 31, and allows the spring m to force the blade towards the wheel until a satisfactory weld is obtained, and then to depress the trip lever t and allow the spring x to break the circuit. The two parts of the slotted copper jaw-holder c, Fig. 11, are closed by levers and links 66, 68 and a handoperated cam or an electromagnet 76, or, according to the Provisional Specification, two vertical electromagnets may act on two hinged iron arms which almost touch at the ends of the jaws. The current may be switched on and off automatically. A sleeve 50 is secured to the shaft 25, and carries loose driving-pulleys 53, 54 with conical bosses to engage the sliding clutches 55, 56 secured to a rod 52, screwed at 59, and fitted with a nut 60 working between adjustable stops 61. When the shaft 25 has rotated sufficiently to turn the crank 22 through half a revolution. the nut 60 engages a stop 61, and throws the operating clutch out of gear. The other clutch may then be thrown in gear by means of the lever 62.

Title: Improvements in Recording Locks.
Inventor: VILBISS ALLEN DE
Filed: 1903-08-27
Granted: 1903-10-22
Abstract: 18,490. Vilbiss, A. de. Aug. 29, A.D. 1902, [date applied for under Patents Act, A.D. 1901]. Time-checking apparatus for workmen. A lock is provided with means for recording the time at which it is operated, and also the key which is used. The recording- mechanism is actuated by the motion of the key bit 4. The time indicator comprises the minute wheel 11 and hour wheel 10, on the edges of which are type characters. The clock mechanism wound by the spindle 14 is placed preferably inside the hour wheel 10, and is arranged to turn the wheels intermittently onetwelfth of a revolution, so that the uppermost characters indicate the approximate time. The key indicator consists of the wheel 20, having characters 23 on its edge to represent the different keys. The key bits of the different keys are made of slightly-different lengths, and, when the key is turned, the bit raises the lever 26 against the action of the spring 29, and, by means of the rack 25 and pinion 24, turns the wheel 20 and brings the character corresponding to the key used under the platen 50. In travelling over the curved neutral surface 32 of the lever 26, the key bit prevents the lever from descending. The hub 21 of the wheel 20 is notched, and is engaged by the spring 22 to steady it. The key bit engages a shoulder in the bolt 6, and, in withdrawing the bolt, causes the roller 55 to ascend the cam 56. This actuates the lever 51 and brings the platen 50 down upon the wheels, printing the time and the characters corresponding to the key on the paper strip drawn from the roll 42. The stop 54 prevents the bar 53 from swinging in the direction in which the cam moves. The type is inked by the roller 39, faced with felt. The paper strip is drawn off the roll 42 by the drum 40, operated by the ratchet 45, Fig. 2, on the pivoted lever 44, the end 48 of which is engaged by the key bit. The lever 44 has preferably a spring knucklejoint 49, so as to permit the key to move in the opposite direction. In the modification of this part shown in Fig. 3, the ratchet-wheel 46 is operated by the pawl 450, pivoted to the bolt 6. The wheels may have characters 100 on the sides, viewed through holes 101 in the lock casing. It is stated that other methods may be employed for printing the record, such as dies which would indent or puncture the strip, and that other means may be used for actuating the various parts.

Title: Improvements in Appliances or Means for Protecting Sown Seeds, Growing Vegetables and Plants and the like
Inventor: CORBETT ALBERT SAMUEL
Filed: 1904-03-02
Granted: 1905-01-12
Abstract: 5145. Corbett, A. S. March 2. Seed and plant protectors.-In appliances of the kind described in Specification No. 12,744, A.D. 1903, for protecting bulbs, sown seeds, seedlings, sproutings, shoots, growing vegetables, and other plants, and the like, means are provided for loosening or tightening the threads, cords, wires, &c., for automatically keeping them taut, for temporarily moving them to expose the plants, and for scaring birds. Fig. 1 shows one way of adjusting the threads. An adjustable and removable thread-carrier d is connected to one of the fixed standards b by one or more screws e passing through eyes e<1> and provided with nuts e<2>. In a modification, the thread carrier slides on screwed arms projecting from the standard b. Swivelling screws may be fitted to screw into the standards, or any other arrangement of screws may be employed. The bar d may be arched or straight. In another arrangement, the arms projecting from the bar d or the standard b are plain or perforated, and adjustment is made by means of clamping-screws, set-pins, cottar-pins, or the like. In order to keep the threads taut, compression springs are inserted between the standards or carriers and heads or nuts on the screws, or on arms on which the carrier slides. The thread carrier may be directly connected to the standard by tension springs. In order to render the plants more easily accessible, a thread carrier of any length is centrally pivoted to the top bar of the support, and is normally held in place on top of the standard by a pin or other fastening. In modifications, the carrier is hinged to the support at one end, or centrally pivoted on it, so that it may be turned into a vertical position. Fig. 16 shows another modification, in which the threads are carried by pivoted segments d<2> capable of being closed up together. In another modification, the thread bars are completely detachable from the standards, being provided with pegs to fit into holes or sockets in the top bars or other parts of the standards. The thread bars may be staple or gable shaped, and may be arranged to carry wire netting. The standards may be provided with upright perforated bars to allow of adjustment of the height of the protectors. Tensioning-appliances may be applied to all the thread carriers. Fig. 19 is an end elevation of a rotatable cage-like protector in which the threads are carried by wheels, discs, or the like i, which rotate when the threads are touched, and thus scare the birds. The pivots of the wheels may be vertically adjustable in a series of holes in the standards, and two or more wheels may be mounted on one standard.
Patent GB-190407085-A (GB)
Title: Improvements in the Feed Motions of Machine Tools Grinding Machines and the like.
Inventor: LIEBERT HENRY
Filed: 1904-03-24
Granted: 1905-01-26
Abstract: 7085. Liebert, H. March 24. Lathes; shaping milling; feed-motions.-In a feed -motion for contour work in lathes, also applicable to shaping, milling, grinding, and other machines, the tool a is held on a floating slide b, Fig. 1, to which is attached a roller which works between reversed scrolls or spiral cams c<2>, c<3>. The scrolls are carried on shafts c, c<1> driven at the same speed, and their shape is such as to give the contour desired. The traversing motion is obtained from a lead-screw b, and may be accelerated or retarded by means of a second pair of scrolls. The roller actuated by the latter has a lever which carries a rack operating a pinion by means of which relative motion between the slide-rest and the nut which engages the lead-screw is obtained. In a modified form, Fig. 6, the traversing motion is obtained from scrolls d<11>, d<12 >placed at right-angles to the axis of rotation. In this example, also, two rollers d, d' working on the outside of the scrolls are used to copy the motion from scrolls to the tool a<3>, and the scrolls are themselves provided with right and left handed screws d<4>, d<5> engaging with nuts so that they rotate as they slide along their feathered shafts d<8>, d<9>. This construction enables the contour of the scroll to be spread out and thus give wider bearing-surfaces for the rollers to operate on. The application of a similar feed-motion to a shaping- machine is also described, and, by substituting a milling-cutter or grinding-wheel for the cutting- tool, the apparatus can be applied to milling and grinding machines.

Attached to the bar 18 of the carriage frame is a toothed rack 24 in gear with a pinion 25 or a shaft provided with a toothed wheel 29, Fig. 3. The pinion 25 is connected to the wheel 29, so as to rotate in one direction, as the carriage is drawn along by its spring drum when writing, by a ratchet and pawl 31, 30. The teeth of the wheel 29 are engaged by stops 34 on a wheel fixed to a shaft 33 at right-angles to the shaft 26. The teeth 34 are in several rows, three in the case illustrated, the teeth of each row being staggered in relation to the other rows. On the shaft 33 is a ratchetwheel 35 which is turned one or more teeth at each depression of a key, so as to permit the wheel 29 to pass one or more of the stops 34 and thus to space the carriage one or more steps. The ratchet-wheel 35 is rotated by a pawl 39 operated by an arm 41 connected by a rod 42 to the universal bar 12. The keys are caused to depress the bar 12 to different extents, according to the width of the characters operated by the keys, by means of notches or projections in or on the keys. The keys representing the widest characters are formed with projections, those representing characters of intermediate thickness are plain, and those representing the narrow characters are notched or recessed where they engage the bar 12.

Granted: 1904-11-24
Abstract: 16,320. Grossmann, A. July 23. Speed indicators. -The speed of a shaft is determined by intermittently coupling i for fixed intervals of time to an indicating-counter, graduated, in accordance wit h the fixed interval, to show the speed. Clockwork p e r - forms the coupling and uncoupling by means of electromagnets. The shaft 1, of which the speed is to be determined, drives one part 1<b> of a coupling, the other part 1<a>, sliding on but rotating with the spindle 3, being forced into engagement normally by the spring 16, and withdrawn when the electromagnet C is energized. When the parts are coupled, the bevel-wheel 14 is turned against the torsion of a spring 2, which is fixed thereto and to the framework 15, and the bevel-wheel 11 rotates the disc a by means of a pin b engaging with a catch 4, thereby rotating the indicating-hand 8 through the wheel work 9. If the electromagnet C be now de-energized, the spring 2 will return the parts, but the disc a and the indicating-hand will be held in position by a brake 5 upon the disc, the spring 6 between the wheel 11 and the disc being consequently put under torsion. If, now, an electromagnet releasing the brake be energized, this spring will return the disc a and the indicator hand to zero. The energization of the electromagnets at the required intervals is effected by clockwork. The rack 10 carries a recording- style.
