Title: Improvements in Apparatus for Measuring the Magnetic Properties of Materials.
Inventor: BAILY FRANCIS GIBSON
Filed: 1901-05-01
Granted: 1902-04-24
Abstract: 8943. Baily, F. G. May 1. Magnetic measurements. - The permeability of two iron or other specimen rods, with a definite magnetizing force, is measured directly by making them the chief parts in a magnetic circuit, magnetizing them by passing a measured electric current through surrounding coils, causing a part of the magnetic flux to deflect a freely-movable magnetic system, returning this to a zero position by adjusting the position of a small coil carrying the same current, and observing the position of the coil on a stationary scale. Hysteresis may be observed by use of different magnetizing-currents. Fig. 4 shows a section of a suitable instrument. The two rods are placed parallel and extend through long magnetizing-coils. The rear ends of the rods are clamped in holes in a soft iron block, and their front ends I are clamped in two blocks B, separated by a thin flat plate of copper G. The magnet system S' may consist of two magnets, arranged astatically, and suspended with two poles near the copper plate G, the upper poles being within the small coil C, which can be turned on a horizontal table. The magnet system has a pointer P extending between stops, which allow a small movement from a zero mark. The small coil carries a pointer over a graduated arc. In modifications, a single movable magnet is used, either inclined, or placed horizontally between the copper plate and the lower part of the adjustable coil, which may be movable bodily away. The Provisional Specification mentions subdivision of the magnetizing-coils.

Title: Improvement in Overseaming Machines.
Inventor: NORTH WILLIAM STANLEY
Filed: 1902-01-02
Granted: 1902-03-20
Abstract: 167. North, W. S. Jan. 2. Overedge-stitching machines; doubleloop stitching-machines; knitted-fabric sewing-machines; ornamental-sewing machines; trimming or cutting. - Cooperating with the usual vertical eyepointed needle are a loop-taker S, Fig. 7, which carries a loop of needle thread up over the edge of the work, and a threaded looper L, which penetrates this loop of needle thread, and the loop of which is penetrated by the needle. The looper L is arranged at right-angles to a shaft mounted wholly above the work-plate and inclined upwards away from the needle-bar, the looper L thus moving in a curved path inclined to the cloth plate, from a point in rear of and to one side of the needle, to a point in front thereof. The looptaker S is operated by a pair of cranks 20, 21, on which it is mounted. A stationary pair of cutters are provided to trim the edges in advance of the needle, and, to vary the width of the seam, the needle is shifted laterally. For this purpose, the needle-bar is mounted in a swinging frame, carrying, on an arm 59, Fig. 4, an inclined stud 67 engaged by the forked end of a lever 63. In the other end of this lever is a screw 73, which is normally held by a spring 76 in contact with an adjustable stop 77, so as to fix the position of the needle-bar. The lever 63 may be raised by a treadle, and is automatically returned by the spring 76. The needle-bar, looper shaft, and loop taker are operated in a usual way through ball-jointed links. Governing needle thread and under thread.-The needle thread pull-off and take-up is shown in elevation in Fig. 4, and to a larger scale in plan in Fig. 3. The needle thread passes through the normally-fixed eyes 84, 85, and through an eye 87 in an arm 83 on the top of the looper shaft. The movement of the eye 87 to one side of the line joining the eyes 84, 85 effects the pull-off, and to the other side the take-up. The eye 84 is adjustable on the machine arm, and the eye 85 is connected by a link 86 to the needle-bar frame, so that the thread is supplied in accordance with the width of seam. The pull-off for the looper thread, Figs. 3 and 4, comprises the stationary thread eyes 91, between which moves a fork having thread-engaging shoulders 90. A cam plate 92 situated in the fork is connected with the lever 63, so as to determine the point at which the thread is disengaged from the shoulders 90, and therefore regulate the supply in accordance with the width of seam.

Patent GB-190206395-A (GB)
Title: Improvements in Typewriting Machines.
Inventor: FELL JOHN CORRY
Filed: 1902-03-15
Granted: 1902-05-15
Abstract: 6395. Fell, J. C., [Felbel, J.]. March 15. Type-writers. - Relates to the spools, winding- mechanism, and ribbonvibrators, which constitute the inking ribbon mechanism of typewriters. The ribbon 12 extends across the machine between spools 13, one of which is shown in section in Fig. 3. The driving-shafts 14 of the spools are slotted at their upper ends, and in the slots are pivoted at 20 blocks 21 bearing spring arms 22 terminating in latches 23<a>. When the spool is placed on the shaft and pressed down, it overrides the latches 23<a>, which then open outwards and lock the spool in position. A pin 26 extending upwards from a collar 25 on the shaft 14 enters an aperture in the bottom flange 17, and positively drives it. When it is desired to release the spool, a thimble 24 is pressed down, thus exerting a cam-like action on the latches 23<a>, which are forced inwards so as to free the spool. Each of the shafts 14 carries at its lower end a bevel gear 31, above which is a friction spring 32 to prevent the spools from turning too freely. The gears 31 engage with pinions 33 on shafts, which bear at their rear ends the pinions 36. On a transverse shaft 38 are mounted pinions 37, either of which can be brought into gear with the corresponding pinion 36 by sliding the shaft 38 longitudinally. The shaft 38 is provided near its centre with an annular groove in which engages the front end of a pivoted snapping-catch, which renders an intermediate or inoperative position of the shaft 38 impossible. The sheave 49 of the carriage-driving spring drum bears a pawl 50, which actuates a ratchet-wheel 51 during the forward movements of the carriage. The ratchetwheel is secured to a bevel gear 52, which is always in mesh with a similar gear 53 loosely carried on the shaft 38. A sliding clutch connection 57 between the gear 53 and the shaft enables the aforesaid longitudinal movement to be given to the shaft when reversing the ribbon. The usual crank handle 63 is provided on the shaft 38. The ribbon vibrator is shown detached in Fig. 8. It consists of a single stamping, of which the edges 75 are folded inwards, so as to engage guiding- grooves formed in the outer side edges of the type guide 11. The guiding slots 81 for the ribbon incline downwards and outwards, as shown. The vibrator is actuated by a link 68, which receives movement from the same universal bar that actuates the escapement-dog rocker. The housings 84 which surround the spools are formed with rearwardly-inclined guiding-slots 88, Fig. 2, which deflect the ribbon downwards and prevent it from creeping upwards on the spools.

Abstract: 4611. Lyon, C. E. Feb. 27. Single-acting engines; valves and valve gear; valves, reversing. - Relates to a single-acting engine, in which the connecting-rod end acts as the distributing-valve. In the engine shown in Fig. 2, the connecting-rod is secured by a cottar e to a cylindrical plug d, which oscillates in a hole through the piston a. The connecting-rod and crank work in a closed chamber. The cylindrical plug d is formed with recesses or passages g, h, which make communication between passages i, and passages o, m, n in the piston. The passage.i, as the piston reciprocates, communicates with the steam pipe k, and the passage j with the exhaust pipe l, while the passages m, n, o lead to the interior of the cylinder. The engine can be reversed by means or a valve p, which slides in guides on the upper face of the piston, and covers either the port m or the two side ports o, n. The valve p is moved by means of a cam t on a vertical spindle u, which passes through a stuffing-box in the cylinder cover and through the boss of a reversing-lever w, with which it is connected by a slot and key. The boss of the lever turns in a bearing at the head of a bracket x. In the modified arrangement shown in Fig. 3, the rod u reciprocates in a vertical tube z, with which it is connected by a slot and key. The sleeve z has a hemispherical head, and turns in a seating in the cylinder, against which it is forced by the steam and by a spring 5, which is confined between the reversing-lever w secured to the sleeve z and the boss 3 on the cylinder cover.
