Title: Improvements in Screw Cutting Machines
Inventor: LAKE DAVID
Filed: 1901-05-10
Granted: 1901-07-20
Abstract: 9719. Lake, D., and Crellin, E. W. May 10. Milling; lathes.-A machine for cutting screw-threads has a bracket bed B', vertically adjustable on a standard A by a screw C' and gearing, a handle being placed on the shaft C which has a pointer and scale. A milling-cutter i is carried in a segmental headstock g, angularly adjustable on the standard to set the cutter at the desired angle across the work W. The cutter is driven from a cone pulley h<7>, through gearing inside the standard, belt pulleys h<3>, h<2>, shaft H, and spiral gearing h. The rod W to be cut is carried by a chuck D<2> free to rotate on the end of a screwed sleeve D, through which the rod passes. The sleeve is journalled in a carriage D<5>, and engages a half-nut in a bracket secured on the bed. The sleeve is rotated by change gearing p from a shaft N', driven by spiral gearing n from the shaft H, and the chuck is rotated by gearing d' and a shaft M driven by the change gearing p. The rotation of the sleeve and rod at relative speeds determined by the change gearing causes a thread of the desired pitch to be cut, the shape being determined by the cutter. The carriage travels on guides E, one of which has a rack S, with which gears a pinion s<2> on a hand-operated spindle s<1> carried by the carriage, so that the latter can be quickly returned when the half-nut is disengaged. The work is guided and steadied under the cutter by V-blocks J, mounted on the bed and set up by screws. These are caused to grip the rod when the chuck is opened and the carriage moved back to bring a fresh length of rod forward. If it is desired to cut close up to the chuck, as in making bolts, the blocks J are drawn back, and a second set K used, these bearing on the threaded part of the work. A finishing-cutter L is mounted on a slide L<1> between the two pairs of blocks to clean and finish the thread after the milling-cutter,

Title: Improvements in and relating to the Stowing and Lowering and Raising of Boats on Board Ship.
Inventor: WADSWORTH FRANCIS HENRY
Filed: 1902-05-08
Granted: 1902-12-24
Abstract: 10,568. Wadsworth, F. H. May 8. Boat raising, lowering, disengaging, supporting, and securing gear.-Relates to apparatus for stowing, lowering, and raising boats on ships. Each boat 4, Figs. 1 and 2, rests in chocks 3 of the form shown and adapted to slide in inclined channelshaped ways 1, preferably of metal, secured to the deck by supports 6 and bolts. The chocks are, preferably, locked to their guides by pins or bolts 9 carried by a sliding frame 5 operated by a handlever 10, to which it is connected by a pin and a slot. Each chock, preferably, has a hinged joint, so that, when its lower portion passes beyond the ship's side, it falls down and frees the boat. When the chock falls overboard, its loss is prevented by a line or chain. The davits 13 are set a sufficient distance apart to allow the boat to swing outwards without canting, the boat being suspended by the usual tackle 14 and gripes 15, which may carry rings or links to engage the bolts 9. Bolts 19, carried by short chains, are used to hold the boat in place temporarily. To check the boat from going out too quickly, a bridle 16 is, preferably, secured by a line 17 to a cleat or the like on a stayed standard 18. A number of boats may be stowed side by side on launching-ways connected by horizontal transverse rails extending across the ship, the locking-frame in this case being operated by a screw and a hand-nut. In a modification, one section of each chock is carried by one of the curved arms of a duplex davit, preferably of compressed steel. The davit arms are connected together by stays and slide in the launching-ways. The other section of each chock is, preferably, formed partly of metal and partly of wood, and the two sections are connected together by a hook catch. The davits are, preferably, secured to and operated by a wire, cord, or chain wound round a winch drum, stops being provided to limit the travel. Fig. 10 shows a modification in which the supporting-chocks 3 are connected by rods carrying rollers 32 guided by channel-beams 1, in which they are traversed by hand-operated chain gearing to which the rods are temporarily connected by hooks 41 or the like. Boats, mounted as shown in Figs. 1 and 2, may be mounted between and connected to the duplex davits.
Patent GB-190211618-A (GB)
Title: Improvements relating to Apparatus for the Manufacture of Chains.
Inventor: LEMAITRE GEORGES
Filed: 1902-05-21
Granted: 1903-05-21
Abstract: 11,618. Lemaitre, G. May 21. Bending; shearing.-Consists of a machine for. making ovallink and like chains from wire. The wire is fed by rollers a, a<1>, Fig. 1, so that its leading end abuts against the further side of a guide-way formed in the framing of the machine. A ram d fitted in the guide-way is then raised, Figs. 8, 9, 10, and 11, shears off the length of wire required for one link, and carries it upwards into contact with the mandrel g, which has been advanced to bring the larger of its acting parts into the plane of the wire. The ram is fitted with a sheath d<1> and with a spring clip d' which serves to hold the blank down upon it. All these parts move upwards together on a carriage f, but, after the blank has been pressed into contact with the mandrel and become slightly bent, the dies e, mounted on horizontal slides one on each side of the mandrel, are advanced to press the blank round the mandrel, and one of them, being provided with an inclined finger e<1> which makes contact with a projection on the sheath, pushes this downward, leaving the top of the ram clear. The movement of the sheath, through the agency of a spring d<5> which normally rests in a notch, pushes back the spring clip. The dies, having advanced and pressed the blank round the part g' of the mandrel, rest while the mandrel is moved back and then advance to close the blank round the smaller part g<5> and finish the link in engagement with the last-formed link which lies in a groove in the mandrel. On the descent of the ram the sheath d<1> is held up by the spring d<2> until the spring d<5> re-engages the notch d<6> and the spring clip resumes its normal position. When the wire orifice in the guide-way is uncovered, the rollers, which had in the meantime been slipping over the wire, now advance it as before. The finished chain is taken off by a wheel overhead through a vertical slide h adapted to be turned on its axis through a right-angle. In a modified arrangement, the ram is replaced by a pair of pivoted arms which act in the same way in shearing off the blank and further to press it round the mandrel for a preliminary bending, the final form being given, as before, by the dies. In another modification, Figs. 21, 22, and 24, the sheath d' and the spring clip d<2> are controlled by a lever d<12> which engages with tappets on one of the horizontal slides. The machine is driven by a shaft c which carries a series of cams and a shaft b geared to the shaft c by worm gearing. An automatic device may be fitted to stop the machine in case of the imperfect formation of a link ; a jockey pulley bears on the chain just below the overhead wheel ; this supports a weighted lever formed with inclined projections which, when allowed to fall, separate the members of the driving-clutch.
