Abstract: 14,958. Mitchell, J. L. Aug. 21. Undercutting &c.-Relates to a chain-cutter machine which is advanced into the coal and then cuts along the face. The base consists of two parts A', A', with link and cam attachments A<4>, so that the rear half A' can be removed when cutting along the face. A slide B, working in guides a<7> on the fore part A', carries the cutter chain and driving &c. gear. The chain is constructed with several forms of links, viz., links h with top and bottom cutters h<1> held by dovetails and a dovetail key and set-screw h<6>; links i with sliding guards i<1>, which are caused to project by advancing the cam plates N so as to mask the cutters h<1> at the side when the machine is advancing into the coal ; links l with central cutters l<1> held in place by slotted eccentric spring pins m and connecting-links j, k. The inner ends of the guards i<1> have hooked ends, and also the connecting - links k have hooked projections which take over the flanges of the slide B. The chain is driven by a sprocket-wheel b<4> tbrough a clutch b<6>, which connects it to the dished spur-wheel b<2> driven by the pinion b<1> on the armature shaft of the motor B<4>. The spurwheel b' is fast on the shaft U, which is thrown in and out of gear, by a clutch operated by a lever with a sprocketwheel o<2> through the slow feed and quick return gearing f, g. When auvancing into the coal, the chain 0 is fixed to the forward part of the frame, and passes round the guide-wheel o' to the driving-sprocket o', so that the cutting- mechanism is hauled forward. When cutting along the face, the guide-pulley q is turned into a vertical position, and the chain is led round it to an anchor fixed on the forward side, while the other end of the chain passes from the driving-sprocket o<2> round a guide-wheel o<3> on the back to a ratchet drum fixed at the other end of the face. By slacking or tightening the chain, and hauling on it, the machine is guided and fed along the face at any desired angle, as it pratically pivots on the guide-wheel q, no guide-rails being used.

After a cuff, rib-top, &c. has been knitted, a slack or tight course or a few rows of waste to be cut are made, and then the frame-needle loops Y, Fig. A, are pressed off, and a draw-thread course, shown in a thin line, is made. Two ordinary courses are now made, and then some of the frame-needle loops or machine-needle loops are transferred to right or left ; for instance, the loops A and B may be transferred to the needle C. A plain course is now made, and then another transferring or lace course, and so on. Welts, tuck-courses, and slack and tight courses, and openwork or lace and plain courses may be made automatically in any order. When the drawthread is removed, the loops W form a fan, as shown in Fig. B and the loops V twist up. The loops are transferred by points G or H, carried by fingers G' on bars F<4> supported by the usual brackets F<3> on shafts F<2>, as shown in Figs. 1 and 2, which show parts of the usual type of machine described in the above-quoted Specifications. An extra set of threads J<1>, with special guides J, may be used to wrap a coloured thread round any particular empty needle A, to produce various effects. In automatically forming tuck courses or welt courses, alternating in any order with lace and plain or ribbed courses, the various parts of the machine are controlled by four sets of cams, any set of which can be brought into action by shogging the cam shaft into four different positions, or by shogging the cam shaft ipto two or three positions, and the trucks into the other positions. In order to prevent wear of the trucks K<1>, Figs. 3 and 4, they are bored out larger than the pin K, and the annular space is filled in with bearing-rollers K<3> retained by washers K<3>. Lubricating-channels are marked K<4>.

Title: Improvements relating to Coin-controlled Apparatus for Delivering Gas and other Fluids
Inventor: REEVES EDWIN ARTHUR
Filed: 1902-10-28
Granted: 1903-03-05
Abstract: 23,572. Reeves, E. A. Oct. 28. Gas meters; liquid meters ; coin action ; coindischarging mechanism. -The delivery valve 22, Fig. 14, of a prepayment gas or other fluid meter preferably has a leather or other yielding facing 23, through which passes a tube 24 with a central partition 25 and a slot 26 at one side. This slot allows a small amount of fluid to pass after the valve is closed. The tube is held in position by a spring plate 27, and is pivoted to an operating-lever 29 on a shaft 28 mounted in plates 6. This shaft has a slotted arm 34, Fig. 2, engaged by a pin 33 on an arm 32 carried by a shaft 30 carrying another rock lever 31 with a notch to engage an operating-tooth on a disc 12, Fig. 1, loosely mounted on a spindle 8. This spindle is operated in one direction by worm gearing, as shown, from the shaft 3 which operates the meter recording-mechanism 4. The spindle 8 carries a fixed wheel 9 and a loose wheel 10 geared together through pinions 14, 14<a> mounted on a wheel 11 integral with the disc 12 and geared, as shown, with pointers 88, which indicate the amount of unconsumed fluid paid for. The valve is opened by coin-controlled mechanism arranged in a casing 35 and consisting of a drum 36 having a radial slot 40 to admit a coin into a pocket carried by a disc operated by a handle 43. The drum has an annular flange 37 secured to the casing by bayonet joints. The coin depresses a spring-raised lever, which enters a slot in the coin pocket and is connected by levers and links to a lever the end, which is thus brought into the path of a lug 73 on an arm 56<a>. This arm is fixed to a plate 56 adjustably clamped to a slotted graduated plate 55 by a screw 62 to vary the price of the fluid, and carries a spring pawl 57 engaging a ratchet disc 59 geared as shown to the shaft 8. The coin is discharged through an opening 38, return of the coin pocket before discharge of the coin being prevented by a lever 68 held against a stop 64 by a spring 65. The disc 55 and the pawl are returned by the action of the coin-controlled operating-lever on a lug 60. The motion of the different parts is limited by stops. To prevent more than a certain number of coins from being inserted in the machine at once, a spring-supported stop lever is arranged with one arm in the path of a pin 92 on the wheel 86, so as to bring its nose 91 into engagement with the carrier when the maximum number of coins have been inserted.

Title: Improvements in Electric Arc Lamps.
Filed: 1903-01-13
Granted: 1903-11-19
Abstract: 896. British Thomson-Houston Co., and Murphy, E. J. Jan. 13. Arc lamps.-To prevent the pumping of brake lamps when starting, the weight, the movement of which by the regulating-solenoids applies the brake, is so formed and placed that its inertia tends to apply the brake more forcibly when the carbons are suddenly checked in separating. The brake band h is fixed at both extremities to the weighted lever k, which is pivoted at o to one end of an operating-lever m, centred on the same shaft as the brake wheel. The other end of the operating- lever is connected by the rod n to the regulating solenoids. On starting the current, the rod n rises and the lever m moves the end of the lever k off the brake-releasing stop l, applies the brake, and separates the carbons. The motion is suddenly arrested by the dash-pot, but the inertia of the lever k binds the brake more tightly. The action may be intensified by a flat spring placed as shown, and may also be applied to other forms of braking.

Granted: 1903-05-21
Abstract: 8248. Zimmer, E. April 9. Lighting gas.-Ignition by catalytic igniters mounted upon the upper end of lamp chimneys is rendered more certain, and the igniters are protected from the products of combustion escaping after the gas has been ignited, by the employment of a sheet-metal or mica deflector a, v, arranged somewhat like a slipper pivoted at d with its sole uppermost. The heel a, which rests upon the edge of the chimney c when the burner is not alight, is counterbalanced by an adjustable or other weight g on the toe v. When the gas is turned on, it is deflected by the sole on to the catalytic igniter z, which is mounted within, or upon, an independent support immediately in front of the open toe part, and the gas is ignited. The ascending products of combustion then turn the heel a of the counterbalanced sole upon the pivot d. Slippers or deflectors constructed of mica may be formed in two or more parts connected together, and the toe part may be secured by wire hoops, or by a metal sleeve, which may also serve as the counterbalance weight.
