Abstract: 5758. Bowell, G. B. March 18. Electric clocks.- Relates to an e l e c t r o-magnetic rotary step-by-step device suitable for secondary electric clocks &c. An iron disk c, with shaped projections as shown, is mounted to rotate in the field of an electromagnet a. An " all-or-nothing de- "vice," on the break of the electric current, moves the disk farther forward so as to bring it into its most favourable starting position for the next cycle of operations. The "all-or-nothing device" may consist, as shown in Fig. 1, of two pins n on the disk, and a lever m pivoted at h and weighted with an iron bar d, which is raised when the electro-magnet is energized. The pins are free to revolve when the lever m has moved to the left. A banking-spring is arranged as shown. The pins may gear directly with a wheel, or be fixed to one of a train of wheels as shown. The electro-magnet may act directly on the arm m. In the form shown in Fig. 2, a spring m or a spring lever or weighted lever bears on the pins n; or the spring m acts on a cam on the arbor. Gear-wheels or a worm-gear may be used instead of the two pins.

Granted: 1906-03-08
Abstract: 21,325. McNeil, J. Oct. 20. Sliding valves.-For discharging large vacuum pans and the like, a circular valve having an inclined surface upon its back is carried upon a truck having a counterpart surface, means being provided for moving the truck to and fro and for moving the valve up and down the incline on the truck. The valve A, Fig. 1, engages a seat C and is carried upon a laterally-moving truck D, having flanged wheels E running upon tracks F. The upper parts of the sides of the truck are inclined and carry antifriction rollers G which engage the edges of inclined depending webs H formed on the back of the valve. The truck may be moved by any convenient mechanism, such as a screwed spindle J and a rotatable nut (not shown). When the truck is moved to the right, the weight of the valve causes the latter to descend the incline until lugs K on the truck engage tappets L formed on the web M of the valve. The valve and truck are then drawn clear of the orifice. When the truck is moved back again, the valve is simultaneously moved back until a projection N thereon engages the edge of the seat, when continued movement of the truck forces the valve tightly on the seat. Engagement of the lugs K with tappets 0 prevents excessive wedging action. The various details may be modified.

Title: Improvements in or relating to the Windings of Dynamo-electric Machines and Electric Transformers.
Inventor: FIELD MICHAEL BIRT
Filed: 1906-01-13
Granted: 1906-10-18
Abstract: 966. Field, M. B. Jan. 13. Armatures; field magnets.-Conductors laid in slots are formed of a depth decreasing from the root to the mouth of the slot, or the layers are made of conductors having different specific resistance, so that the sum of the ohmic and eddycurrent losses is reduced to a minimum. The depth of the upper conductors a, Fig. 2, within the slot in the laminated core c is reduced, and the depth of the lower conductors b is increased, as shown. A similar result is produced by reducing the depth of the active portion d, Fig. 3, of the upper conductor, and increasing the depth of the active portion e of the lower conductor b, the end conductors in both layers being of normal depth. The layers of conductors may be of different specific resistance, e.g. the first layer may be of high conductivity copper and the second layer of phosphor-bronze, all conductors having the same cross-section. The end conductors of the core of higher specific resistance may be of material of lower specific resistance. To enlarge the section of the conductor leaving the slot to reduce ohmic losses and present a larger surface for cooling, additional material may be affixed by riveting, welding, &c. In the case of formerwound coils, the lower turns are wound with a number of strips laid one above the other and connected in parallel, the number of strips being gradually decreased as the winding progresses, connexions being made by riveting &c. where each strip ends, to enable the current to distribute itself among the laminµ, The invention is applicable in some cases to stranded conductors. In the case of alternating-current machines, the reduction of depth of the conductors at the parts where the cross flux due to the current in the conductors themselves is a maximum may be used also for reducing the inductance of the winding.

Granted: 1907-10-31
Abstract: 24,667. Bolas, T. Nov. 3. Sensitized plates etc.; developing.- Relates to the preparation of self-developing plates &c., as described in Specification No. 1201; A.D. 1888, in such a manner as to avoid the defects of patchy halation due to the existing methods of applying and separating the constituents of the developer, and also to avoid the waste of materials by reason of the diffusive action between the chemicals.- Alternative methods are described. The developing-materials A, B on the back of the plate may be separated by a neutral material C, having, anti-halation properties similar to that of the developing-materials if the plates are translucent, the plate is coated so that the back is uniformly covered with anti-halation material. A separating-layer of sub-acid material may be used to prevent any alkali from diffusing into the normally acid reducing-agent. Or the constituents of the developer may be separated on one or both sides of a sheet or film other than that bearing the sensitive surface, and the same attached to the plate. When one of the constituents of the developer is translucent and does not react upon the unexposed emulsion, it may be coated upon the front of the film or incorporated with the emulsion; the other constituent being coated on the back of the plate. Specification No. 22,727, A.D. 1901, is referred to in connexion with this method. Again, one part of the developer is put as a margin round the sensitive surface on the front of the plate, and the other constituent is spread on the back. The compositions, when arranged round the margin of the plate, may be coloured or tinted'. Full detailed description of various compositions and formulµ for the developer are given. A preservative solution for saturating the sensitive layer, containing an ammonium salt in combination with hydroxylamine. is used when the reducing-agent is mixed with the sensitive layer and the plate developed by an alkaline reagent. In connexion with the acid or reducing constituent of the developer, the use is described of acids, such as salicylic or citric acid, of sulphites, or of acids and sugar-like bodies either separately or together ; and in connexion with the alkaline constituent, the use of bicarbonates of sodium, potassium, or lithium is mentioned.

Title: Improvements in Machines for Backing and Hollowing Cask Staves.
Inventor: DUNBAR ALEXANDER
Filed: 1907-03-18
Granted: 1908-03-12
Abstract: 6438. Dunbar, A. March 18. No Patent granted (Sealing fee not paid). Shaping by cutting.- In a machine for backing and hollowing cask staves, of the kind in which the stave is passed laterally between revolving cutters, the stave is straightened, clamped, and unclamped automatically, the cutters being moved to give any desired curvature to a bread or narrow stave. A transverse slide 37, reciprocated by a crank and connecting-rod, carries cams 28, 36 and two stops 50, 54, Figs. 1 and 6. The cam 28 engages rollers 29 on a rod 26<a>, which oscillates a quadrant 25 on a pivot 26, so as to raise by slides 18 the work-carrying table and by rods 24 to bring down a presser-bar provided with weighted pressers 21 to straighten the stave. The cam 36, through a block 35, rod 34, and lever 33, oscillates a shaft 31, so that, through a lever 30 and rod 32, a frame 1 comprising two side pieces 8 and a rock-shaft 2 is reciprocated in guides 3, Fig. 5, in the main frame. The frame 1 carries slides 5 provided with clamping-bars 6, Fig. 5, normally held in clamping position by rods 9, 10 and spring- controlled or weighted levers 7, 8 on the rockshaft, but periodically released and returned to position by the stops 50, 54, which respectively raise the lifting-bar 39 and diagonal levers 40 or allow them to fall ; the stop 50 strikes a finger 51 on a rod 46, and the stop 54 strikes the end of the rod. The rod 46 is pivoted at 47 to a block 43, which through a roller 48 and cam 49 on the frame is consequently moved in guides 45 and operates the levers 40 through the rod 44 and lever 42 on the rock-shaft 41. The rod 46 is retained in the position in which the clamps are open by a catch 52, which is lifted by the stop 54 on the return motion. The roller 48 is held in contact with the cam-way 49 by the weight of the bar 39, levers 40, &c. The bearing-blocks 56 of the cutter spindles 57, Fig. 1, are movable and have rollers 58 resting on templets 59 carried by the sliding frame 1. The templets, which are of gradually varying curvature are movable in transverse slides in the frame 1 so as to adapt the curvature to the width of stave. This is accomplished by the rods 63, which are operated by the rocking lever 7 and carry pins engaging inclined slots in the templets. In another form, Fig. 11, the bearing-blocks engage levers 70 on rock-shafts 69 carrying levers 68 for the rollers 58, which contact with vertical templets 59, which are vertically adjustable by a bell-crank and rod connected with the lever 7. To adjust the upper cutter to the thickness of stave, Fig. 1, the rollers 58 are journaled on blocks 66 adjustable by screws 67 in the bearing-blocks 56. The central parts 12 of the clamps may, be fixed, and the end parts 13 movable in slides 14 by weighted levers 15 loose on the shaft 2 ; or all the parts on either bar may move in unison or independently. The work table may have a loose top supported on ball bearings to allow a slight lateral movement.

Granted: 1908-05-04
Abstract: 10,387. Rost, R. May 4. Rotary disk valves ; plug cocks ; closing, retarding ; shocks, preventing.- Relates to a mixing-valve for baths &c.' capable of delivering hot, cold, or hot and cold water as desired. The-rotary disk valve m is flexibly connected, preferably by an india-rubber disk p, with a hollow cone k. The cone k is connected with the handle n, and is provided with an annular rib o, two transverse ribs o<11>, and a rib o<1> extending around a half of the base of the cone. These ribs form a closed cell adapted to govern the outlet q. The valve m is pressed against its seat a<1> by a spring f abutting against a disk f<1> provided with holes f to allow the fluid to press the disk p uniformly upon the valve. The passage b<1> connected with 'the supply pipe and the passage d<1> leading to a heating-apparatus open into the valve seat a'. When the valve is in the position shown, cold water entering the passage b<1> passes through the hollow cone, the port r in the valve, and the widened opening in the valve seat a<1> of the passage d<1> to the heating-apparatus, and thence. as hot water through the passage g<1> and the annular space u in the casing a to the outlet q. A mixture of hot and cold water is delivered. when the port r lies partly over one of the recesses s, Figs. 2 and 4, in the seat a<1> and partly over the widened opening of the passage d'. When the valve is turned farther so that the port r lies wholly over one of the recesses s, cold water is delivered. When the port r is brought over the lower part of the seat a<1> to close the valve, the friction between the cone and the cap h, caused by the increased pressure of the fluid within the cone, prevents the rapid closing of the valve and the consequent shocks,
