Title: Needle-bar Mechanism for Sewing Machines.
Inventor: MACDONALD JOHN KING
Filed: 1903-01-27
Granted: 1903-12-03
Abstract: 1918. Croll, J., Macdonald, G., and Macdonald, A., (trustees of Macdonald, J. K.), [Singer Manufacturing Co.]. Jan. 27. Sewing - machine needle-driving; buttonhole-sewing machines; multipleneedle machines; overedge-stitching machines; needleholders; oiling of thread, preventing. -Relates to that class of needle-bar operating- mechanism by which differential or irregular movements are imparted to the needle-bars, and consists in arranging this mechanism so that one or more needle-bars may be operated from a rotating crank. The invention is particularly designed for use in driving two out-of-time needles, co-operating with a thread-carrying and a non thread-carrying looper acting alternately, for the production of overseaming or buttonhole stitching as described in Specification No. 18,195, A.D. 1902, and, according to the present invention, two needle-bars are preferably so mounted as to be adapted to be turned, as for stitching around the eyes of buttonholes. Fig. 1 shows a front view of the head of a sewing- machine with parts removed and broken out, and Fig. 2 a plan. The two needle-bars 20, 21 are mounted in grooves in a guide 19, which can be rotated or turned on a vertical axis. Mounted between lugs 22 on each needle-bar are collars 23, 30 respectively, each of which is connected by the linkages shown to one or the other of the pins 15, 16 of a double crank fixed to a crank-head 14 operated by a shaft 13. With this arrangement, the needles reciprocate alternately, and the movements are comparatively slow during the upper portions of the strokes and very rapid during the lower portion, but the linkages may be arranged to reverse this. The needle-bars are cut away, as shown in Fig. 2, to lighten them. The guide 19 is preferably provided with grooves 37, Fig. 2, for the passage of the threads, the grooves being preferably covered with small plates to protect the threads from oil.

Title: Improved Brake Actuating Mechanism for use upon Cycles and for other like purposes.
Inventor: WERNICK HERMANN RICHARD
Filed: 1903-10-16
Granted: 1904-10-13
Abstract: 22,361. Wernick, H. R. Oct. 16. Brakes.-To facilitate the operation of cycle brakes and the valves and switches of motor cars &c., a hand-lever, made shorter than usual, is made to act directly or indirectly upon a second lever connected to the brake, valve, or switch, in such a manner that a rapid taking-up of the slack is followed by slower travel. The two members are so arranged that actuation of either of them causes the distances between the point of working contact and the axes of rotation to constantly change in relation to one another. As applied to a cycle, the pulling up of a lever 1, through an extension 2 and an abutment 7, actuates a small lever 6 connected to the brake. A covering-plate fitting upon an edge 15 of a plate 4 may be provided. If desired, one or two links may connect the extension 2 with the small lever to operate the brake, or a pivoted tumbler may be interposed between the tip of the extension and the small lever, and when a Bowden wire connection is used, an arm, such as is shown at 10, Fig. 6, extending from the plate 4 upon which the levers are pivoted, may be provided to form one of the stops. The mechanism may be arranged between the jaws of an ordinary clip, the pivots of the levers serving to secure the clip to the handle-bar, and the small lever may have a series of holes for the attachment of the brake wire. As shown in Fig. 6, the extension, made sickle-shaped, may engage a roller 22 upon the lever 6, or the lever, without an extension, may be itself curved to pass to the left of the roller. In a further modification for a " push-down " type, the extension of the hand-lever is directed downwards and bears a lug adapted to engage the small lever between its pivot and the point of attachment of the wire. Eccentric toothed segments, or a disc, upon which the wire is adapted to be wound, may be used in lieu of the extension and short lever, and the attachment of the wire may be made by a rack and segment. The abutment may be slotted instead of hollowed out as shown, and the lever then engages with it by its end or by a pin. For a " press-forward " lever, the lever and abutment may be made to act when the axes of the two levers are at right-angles.

Title: An Improved Process for Effecting the Desulphurisation of Lead Ores.
Inventor: SAVELSBERG ADOLF
Filed: 1903-11-11
Granted: 1904-08-18
Abstract: 24,493. Savelsberg, A. Nov. 11. Lead; silver; gold; treating.-The de-sulphurization of lead ores is effected in the converter, without a preliminary roasting, by the addition of limestone. From 15 to 20 per cent. of limestone is mixed with the ore, and sufficient silica should be present. The mixture is wetted with about 5 per cent. of water. To start the operation, the converter is gently heated with the aid of a bed of fuel and limestone, and then the charge is added by degrees. When the converter is full, the blast may be increased, but the temperature is controlled so that complete fusion does not take place. The final product is a solid mass of silicates, containing lead oxide, lime, silica, &c. ; it is turned out of the converter and smelted for lead. The process may be applied to lead ores accompanied by other sulphide ores, such as those of silver and gold.

Abstract: 386. Briggs, W. C. Jan. 6. Cutting tobacco &c.-Fig. 1 shows a plan of the machine for stemming tobacco and other leaves. The leaves are fed by hand on to the part Jw, Figs. 1 and 3, or J<Î> of the belt J, which travels over the pulleys j, j<1>, j<6>, j<7>. Part of the leaf is then nipped between the toothed carrier G and the endless travelling cord N which runs in the groove n<2>. The leaf is thus brought to the stemming or stripping rolls R, R<1>, and stem-drawing or traction rolls T, T', Figs. 1, 10, and 12, which are driven in the direction shown by the arrows. The rolls R, R<1> have threads r<2> which form gradually increasing channels in which the leaf stem travels. Just after the end parts of the wings of the leaf have been separated from the stem, the tip of the stem is cut off by a rotary cutter. The rest of the wings are then stripped off. The stripping may be done from the other end of the leaf. Leaves which have not been treated or have been only partially treated pass back to the part J<w> between the belt J and a second belt J<1> which travels over the pulleys j, j<1>, j<5>, j<4>, j<3>, j<2>. As it travels back, the leaf is nipped between the endless travelling cords W, W<1>, placed in an inclined position as shown in Fig. 1. The leaf is then pulled out laterally and is caught by the cord N. The carrier G is driven from the main shaft B by toothed gearing F, g and drives a spur-wheel on the shaft k<4> connected to the shaft L. The various shafts are connected by toothed gearing and sprocket chains.

Abstract: 18,716. Kenrick & Jefferson, and Jefferson, F. T. Aug. 30. Filing papers and documents. - The drawers of filing- cabinets are made with a compact form of slide, a removable compressor, and a simultaneous locking-device. The drawer a, Fig. 8, has a slot a' extending from front to back, in which extension slides b are fitted flush with the side. The edges of the slot a<1> have tongues a<2> extending from the rear to about the middle, and have grooves extending from the middle to the front. The edge of the extension slide is grooved to fit the tongue a<2>, and at the front.is a stop b<2> sliding in the grooved part of the slot ; or the end of the slide b may carry rollers, Fig. 14, with ribs b<4> for smooth running. At the rear end of the slides b and on the outer faces are stop-bars c, with india-rubber buffers c' working in recesses d in the sides of the drawer. More easy running may be obtained as before by wheel stops. When the drawer is opened, the slides b travel with it until stops c reach the front, when the drawer continues to work on the slides b until the stops b<2> reach the front ends of the tongues a<2>. On closing, the drawer and slides first travel together. The invention may be applied to the bottom instead of the sides. The compressor f consists of a continuous frame-like back having a projecting foot or slide f which is passed through an opening in the bottom of the drawer at the back of a longitudinal slot extending to the front. The foot f<2> is shaped to slide along the slot, and the compressor is kept in position by the pressure of the papers tending to overturn it and causing the foot to grip the bottom. If the compressor from readjustment reaches the back of the drawer, it may be lifted out from the widened end of the slot and the full capacity of the drawer utilized. In addition to the engagement of the compressor with the edges of the slot, it may work upon a wire or rail h, Fig. 8, extending from front to back and tempo. rarily locked in position by the engagement of a pin h<1> on the knob h<2>. The crossing pin h<1> is kept in its inner bearing against the iuner side of the front plate i by a spring k. When the rod h is to be withdrawn, it is rotated to bring the pin h<1> coincident with notches in the plate i when the spring forces the knob and rail outwards. The simultaneous locking-device for the drawers comprises a vertical bar l, Figs. 2 and 6, with a notch at the level of each drawer arranged to coincide with a notch in the plates r screwed at the bottom of the drawers. The upper end of the bar l is connected by a pin l<1> and the crank plate m to a rod n passing from back to front. A second crank plate m<2> is fixed to the rod n and a pivoted plate o connects the plate m<2> to the bolt of an ordinary key lock p. By turning the lock, the vertical rod l may be raised to bring its notches level with those in the plates r, when the drawers can be withdrawn.
