Granted: 1899-08-23
Abstract: 18,167. Powell, E. L. Aug. 23. Wire &c. compensators.-The wire or chain c from the balance lever on the signal post is passed under guide-pulleys d and over the pulleys e', e' on the rocking frame e, the free end being passed once or more round the pulley e' or otherwise prevented from slipping, and having attached to it a weight c', which keeps the wire &c. c under a constant tension. The pulley e' is connected by the pawl f<2> and ratchet-wheel e<5> to the brake drum f on the spindle f the brake strap f<3> being connected at one end to the weighted lever g pivoted at g', and at the other end to the cross-bar h connecting the ends of the bell-crank levers h<1>, which are connected through the link j, bell-crank levers k, and link l to the operating-lever m. One arm of the levers k carries a weight k'. During the first part of the movement of the lever m, the frame e remains stationary, while the brake strap is tightened, and the drum f and pulley e' rotated to take up any slack in the wire. When the cross-bar h comes against the frame, the continued movement of the lever m tilts the frame and lowers the signal. The brake connections prevent any undue strain on the wire &c. in case the signal reaches its extreme position before the lever m is fully operated. In a modification, the parts are,arranged and weighted so that the brake strap is always tight.

Patent GB-190002542-A (GB)
Title: Improvements in Knitting Machines.
Inventor: SALDIN MAX
Filed: 1900-02-08
Granted: 1900-05-05
Abstract: 2542. Saldin, M. July 17, A.D. 1899, [date applied for under Sec. 103 of Patents &c. Act, A.D. 1883]. Parallel knitting-machines.-Relates to a machine for knitting mittens, sweaters, gloves, &c., in which a single large or two smaller tubes to form sleeves or fingers can be produced. A double thread-carrier, shown in Figs. 5, 6, and 7, has a pair of latches J, J<1>, by which its jaws can be closed or opened ; the carrier is connected to a pivoted lever G' rocking between stops and guides to give the required lag in a usual manner ; the latches can slide in grooves in the carrier, and are pivoted by pin K<3> to levers L, L<1> pivoted to the lever G'. These levers L, L<1> carry arms L<3>, L', having turned-up projections L<6>, L<7> adapted to come in contact with fixed cams N and with adjustable cams O, 0'. Spring catches engaging with grooves G<7>, G<8> hold the levers L and L' in one of their two positions. According to the position of the levers L, L', the mouths G', G<5> of the carrier are closed or open. The cams O O<1> are fixed on two shafts P, P', which can be adjusted longitudinally to two positions, and one of them can be rotated so as to place its cam out of the track of the corresponding projection on the levers L, L<1>. In making a large tube, only one yarn is placed in the carrier, the carrier mouth remaining constantly latched. On commencing to make two tubes, the shafts P, P' are adjusted until both cams O, O<1> are in action and comparatively close together, and both yarns are placed in the double carrier. Owing to the action of the cams N and O, O<1> on the levers L, L', the yarns are alternately carried along and dropped, thus making two tubes, but the yarns are both knitted together for a few courses on a few of the junction needles, thus forming a crutch. When the crutch is finished, the shafts P, P' are adjusted, and the cams O, O<1> separated, so that one thread is dropped before the other is picked up, thus making two independent tubes. In a modified form, pivoted gates are used instead of sliding latches, these gates being operated by rocking shafts, bell cranks, &c. and cams analogous to N, O O<1>.

Filed: 1900-02-16
Granted: 1900-05-12
Abstract: 3115. Haddan, R., [Dubessy, M.]. Feb. 16. Swivel looms.-Relates to an attachment to pcwer looms for producing embroidered or tissuefigured fabrics. One or more rows of shuttles 8, Fig. 1, are suspended by brackets 10, 10<1> from a bar 9, having end pieces 11, 11<1> to slide in brackets 12, 12<1> on a sliding frame mounted upon the lay cap 1, and are lowered into the warp, against the action of spiral springs 20' on the shaft 13, by means of a connection 18 from an oscillating lever 43, and intermediate connections 16, 17, 16', 17<1>. These shuttles are actuated for figuring by a sliding rack 24<1>, opetated by a sliding bar 26, bellcrank lever 28, and connections 31, 31<1> from oscillating levers 45. The levers 45 are connected by spring connections 42 to jacquard mechanism, and are held out of action until the moment of picking by a vertically-moving frame 46, Fig. 2, which is released at the proper time by a sliding rod 49, having adjustable stops to engage with an oscillating lever 50; this lever is operated at every swing of the lay by means of a shaft 54, Fig. 1, and connecting-rod 53. The parts of the frame carrying the shuttles are connected together by screwed rods 6, 7, and the whole can slide upon rods a on the lay cap 1. It is moved from side to side by connections 38, 38' from oscillating levers 44, 44<1>, and it is held in the extreme positions by catches 34, 34<1> and inclined stops 37, 37<1> until released by pieces 36, 36<1>, on the rod 35, to which the connections 38, 38<1> are attached. If the shuttles fail to enter their boxes properly, a roll 32<1> fails to enter its notch in the bar 26, and tilts a slotted swinging lever 32 ; this shifts a finger 33 projecting through the slot, and stops the loom. The ordinary weft shuttle is prevented from acting, during the operation of the figuring-shuttles, by putting its picking-motion out of action by connections 56, 56<1> from the levers 43, 55. The connections 18, 31, 31<1>, 38, 38<1> are inextensible metal tapes.

Abstract: 3667. Haenichen, A. Feb. 24. Winding - machines; spindle apparatus; rollers and roller heads.-The yarn is delivered from rotary delivery spindles l, and wound by means of a drum winding - arrangement above. Fig. 1 shows two sets of apparatus arranged one above another, the winding- drum shafts r being driven by suitable gearing from a vertical shaft h driven from the main shaft f. The delivery spindles on the same level are all driven by a single band k, which passes over pulleys j on the shaft hand pulleys n on sliding brackets o, which are automatically forced outwards so as keep the bands at a uniform tension by means of weighted rods g<4>, the ends of which engage with cam surfaces h<2> on the frame. The thread-guide rails u are operated by cams w and spring levers v, and are mounted on brackets i<3>, i<2>, carrying antifriction rollers. Ball bearings are applied to most of the rotating parts. Fig. 2<a> shows one of the bearings of the horizontal shaft f. One set of balls runs in a race formed partly in the pedestal z and partly in an adjustable collar a<1>, while another set runs in a channel in the pedestal and against the face of a collar a<4> on the shaft. Fig. 2 shows the upper and lower bearings of the vertical shaft h. The brackets b<5> are vertically adjustable on the frame. The bush d<3> is also adjustable in the upper bracket, while the lower end of the shaft takes into a suitable aperture in the lower bracket, a collar c<5> on the shaft, or a washer d<1> beneath it, resting upon antifriction balls c<4>, which run in a channel on the upper surface of the bracket. The bearings j<4>, Fig. 5, of the drum shafts r are mounted on vertically-adjustable spindles which are carried by brackets i<4> secured to the frame; k<1> are cups to catch the dripping lubricant. The spindles l are each carried by a bracket m', Fig. 6, which is pivoted to a fixed bracket k<5> and is pressed by a spring n<1> against the driving-band k. The spindle wharve may, however, be held out of contact with the band k by means of an arm p<2>, which may be caused to engage with a spring catch p<4>. The lower end of the spindle takes into a suitable step in the lower part of the bracket, while the upper part of the bracket carries a sleeve n<5>, Fig. 7, which is provided with a ball race to accommodate balls which are engaged by a collar o<4> on the spindle and protected by a screwed cap o<2>.

Title: Improvements in Acetylene Lamps.
Inventor: GENESE DAVID
Filed: 1900-05-15
Granted: 1901-03-30
Abstract: 8973. Genese, D. May 15. Acetylene lamps.-In this lamp for domestic, cycle, carriage, and other uses, the pressure of the gas generated automatically controls the flow of water from a porous chamber, to which the water is admitted as required by means of a handactuated valve, the carbide is contained in a telescopic chamber to allow of the expansion of the residue, and a storage chamber is provided for the gas beneath a practically non-oxidizable, selfcleaning, shadowless burner. Water supplied by the hand-actuated valve 8 to the porous chamber 15 drips into the porous recess 22 and percolates through the porous extension 23 of the telescopic cover 19 of the calcium carbide holder 17. The upper part 21 of the cover 19 slides within a guide 25, of which the upward movement is limited by a stop 30. The upper edge 18 of the bolder 17 and the lower edge 20 of the cover 19 are corrugated to permit of the escape of the gas when the cover is in its lowest position. The gas then traverses the perforated flanges 28, 27 of the guide 25, the pipe 35, and the valve 36 to the storage chamber 31, from which issues the burner tube 32. Acetylene burners. -A flat burner for acetylene gas, in which the outlets of the several independent converging passages are at such distances apart that the separate flames unite to form a solid flame in the same plane as the burner, is produced by piercing a piece 41, Fig. 6, of sheet platinum or other metal with holes 47, by tapered platinum or other mandrels 46, bending over the part 43, forming edges 45, Fig. 9, and pressing in a die 48, Fig. 8. The burner thus formed may then have the mandrels 46 withdrawn, and be fixed in position for use, but it is preferred to jacket it previously with porcelain, lava, or other non- friable and refractory substance, the burner 34, upon removal from the mould 50, Fig. 10, presenting the appearance shown in Fig. 11.
Patent GB-190012278-A (GB)
Title: Improvements in Apparatus for Analysing Gases and Indicating and Recording the Results of the Analyses.
Inventor: ARNDT MAX
Filed: 1900-07-07
Granted: 1900-09-01
Abstract: 12,278. Arndt, M. July 7. Indicating and registering volume of gases.- Relates to apparatus for rapidly performing a number of gas analyses by the absorption of one constituent in a suitable liquid, no cocks, valve?, or tubes requiring to be alternately squeezed and released, being employed. Two forms are illustrated, that shown containing an automatic recording-mechanism in addition to the ordinary scale. The air or gas to be tested enters by a tube 1, passing if desired through a filter 1<b>, and flows into a gas chamber 3 by way of a bend 1<a> and a tube 2. Connected with the chamber 3 is a gas outlet 4, which may also have a filter 4<b>, and the inlet of which is exactly on a level with the zero of the indicating-scale 5. The lower part of the vessel 3 is connected by a flexible tube 6 to a vessel 7 containing water or other liquid 8 to act as a seal. The vessel 7 can be raised and lowered as desired. When the vessel 7 is in the position shown, the gas can pass completely through the chamber 3. On raising the vessel 7, the inlet 1<a> is first closed, and then the outlet 4, after which the enclosed gas is driven through a narrow outlet 9 and flexible tube 10 to a vessel 11<a>, containing balls or tubes 12<a> to increase the surface, and supplied with a suitable absorbing liquid from a vessel 11, which may be below the vessel 11<a> or may surround it. The absorbing liquid is thereby driven downwards, and rises in the vessel 13<a>, and in the outer vessel 11. When the absorption is complete, the vessel 7 is lowered until the liquid levels in 7 and in 3 are the same, the unabsorbed gas returning to the latter vessel. The percentage of gas absorbed is now shown on the scale 5. By lowering the vessel. 7 still further, the apparatus is ready for a second analysis. In the form shown, when gas enters the absorber 11<a>, the air at the top of the vessel 11 becomes compressed, and any desired proportionate amount of it may pass to the elastic bag 16, while the remainder passes up a tube 17 to a receiver 20 dipping into liquid 19 and carried by an adjustable lever 22. The latter is provided with an arm 23<a> having a marking-stud 23 at its free end, which produces a vertical line on paper 25 wound around a rotating drum driven by clockwork. If no gas is absorbed, the receiver would then rise to its fullest extent and the marker would therefore rise to the top horizontal or zero line on the paper, but, if some has been absorbed, it would fail to rise to that line by a greater or less extent according to the amount of gas absorbed. Mention is made of testing furnace and smoke gases, and testing for carbonic acid, carbonic oxide, or oxygen with this apparatus.
