Title: Improvements in, and connected with, Shuttle-changing Mechanism of Looms for Weaving.
Inventor: WALKER ALBERT EDWARD
Filed: 1901-08-12
Granted: 1902-11-12
Abstract: 16,156. Walker, A. E., Walker, A., and Walker, G. Aug. 12. Loom shuttle-changing mechanism; shuttle boxes; weft, cutting.-The shuttles 3 are supplied from a magazine 4 to a rotary shuttle box 2 by means of a feeder 6 pivoted about the same centre as the lay-swords and actuated by means of a cam 12. The feeder is connected by a link 80 to a lever 76, which is oscillated by the usual shuttle box turning- cylinder 60 and its connected mechanism. Spring- actuated sliding-fingers 5 are fitted within the feeder 6 and support the shuttles 3, except when the feeder has come into contact with the shuttle box for the purpose of supplying a full shuttle ; in this position, the fingers are forced backwards by reason of the contact of their front and preferably rounded or conical euds 19 with the shuttle box. During the transfer of a shuttle, the shuttles in the magazine are supported by a curved rest 56 carried by the feeder, which also carries end guides 43 to direct the bottom shuttle in its descent to the fingers. A fixed stop 17, against which the fingers strike during the return stroke of the feeder, ensures their being forced beneath the magazine. The front of the magazine is partially closed by a cover 39, beneath the cloth side of which the weft threads pass from the shuttles 3. Grooves 38 formed in the ends of the magazine, and a central guide 45 on its rear side, serve to guide the shuttles 3 during their descent. Each compartment of the shuttle box has a spring- pressed bar 22 normally projecting across the entrance to the compartment, and having an inclined surface against which the incoming shuttle presses so as to force the bar backwards. During the passage of the incoming shuttle into the box, the swell is pressed backwards by a projection on the central part of the bar 22. The Provisional Specification states that the swell may be released by means of a spring buffer or projection on the feeder. Simultaneously with the transfer of a full shuttle, the empty shuttle is released by means of a spring presser 35 mounted on the feeder and adapted to strike against the ends 34 of two levers 30 pivoted to a plate 21 to which the corresponding bar 22 is attached. In fast-reed looms, each shuttle compartment has a swell, such swells being arranged to engage the stop-rod finger in succession; to this end, the arrangements described in Specification No. 15,998, A.D. 1901, may be employed. The weft is severed at the selvage by means of a knife 59 on the lay, and shearing-edges formed on a plate secured to one end of the shuttle box. The shuttle box checking-mechanism described in Specification No. 15,998, A.D. 1901, is preferably used in conjunction with the shuttle box turning- mechanism.

Title: Machine for Wrapping Pamphlets or similar Articles.
Inventor: FAIRWEATHER WALLACE
Filed: 1902-05-06
Granted: 1903-03-19
Abstract: 10,383. Fairweather, W., [Sheldon, E. P.]. May 6. Wrapping - up newspapers, pamphlets, &c.- Pamphlets, newspapers, ..,&c. are automatically formed into a roll and enclosed in a gummed wrapper. The pamplets 14 are taken singly by an oscillating sucker 151 and delivered to a wheel 29, where each is seized by a gripper 160 and conveyed to the recess 23, where it is released and rolled up by rollers 30, 31, 32, 33 geared up so as to revolve in the same direction. A wrapper is cut off from a web by a knife 100, gummed by a pad 130, and fed into the recess by a finger 84, when the pamphlet has reached the condition shown in Fig. 8. Guides 200, 227, 201 assist in forming the roll, and the last guide recedes as it is completed. When it is quite wrapped up, it falls into a recess in the wheel 29, and is carried past the guides 200, 207, and expelled by a finger 175 on to a travelling band 233, by which it is conveyed along under a guide 238 out of the machine. The shoot 13 for supporting the pamphlets has a grid bottom 16, which turns about the shaft 17 and has hooks 19 at its forward end which release the pamphlets one by one. These rest against a stop 232 at the top, and may be pressed forwards by a weighted frame, a plate being thrust upwards between them at every operation to relieve the forward ones of pressure. The rollers 29, 30, 31, 32, 33 are made up of numerous wheels with gaps between them, the wheel on one shaft coming opposite the gaps on the adjacent ones. The wrapper web is fed forwards by rolls 51, 53, driven by change-speed gearing, comprising a stepped-tooth wheel 66, engaging a wheel 67 on the arm 69. The rolls 51, 53 feed the web continuously and cause it to hang in a loop, to be drawn upon by the intermittentlyacting feed-rolls 57. The gumming-pad 130 receives its gum from a horizontally-reciprocating roller 116 which travels between it and the roller 111. The wrapper blank presses under guides on the table 80, being fed forwards by a finger 84, which engages a hole in the blank and is raised and lowered by its bell crank 85 working over a cam surface 87, and by rollers 190, 223. The gripper 160 is opened to receive and release the pamphlet bv fixed cams, such as 165, engaging its lever 162. The gripper may press the edge of the pamphlet into a recess in the wheel 29 and form a bend, which facititates the beginning of the rolling process. The ejecting-finger 175 is worked by a cam 174 acting on its lever 173. The sucker 151 is controlled by an oscillating valve on its trunnion 149, which puts it into communication alternately with the atmosphere and its exhausting-pump 144. The machine has two active belt pulleys, so that the belt may drive the exhausting-pump alone, or both the pump and the wrapping-machine.

Abstract: 24,542. Kellner, C. Nov. 8. Raw materials, treating.-In a modification of the process described in Specification No. 5420, A.D. 1890, for the production of cellulose, for use in the paper industries, by the treatment of plants with the electrolytic products of an alkaline or metallic chloride. the cathode products of the electrolysis, e.g., alkalies and alkaline carbonates, are reserved for the market. The plants are treated with water, or preferably with milk of lime or a dilute solution of an alkali or alkaline carbonate, and, after removal of the excess of liquid by a hydro-extractor or by pressure, are subjected to the action of chlorine gas obtained from the electrolytic cell. The incrusting - substances (lignilies) in the plants are thus oxidized and rendered soluble in hot water or dilute alkali, and the plants are then immediately removed and treated with hot or cold water to remove the soluble portions and the hydrochloric acid produced. Any incrusting-substances still remaining with the cellulose is removed by treatment in a hot or cold bath of milk of lime, or dilute solution of alkali or alkaline carbonate, or both in succession. The residue, consisting of almost-pure cellulose (vegetable fibre), is washed, and may be bleached, and is then dried and employed as a raw material for making paper.

Fig. 1 shows a side elevation, partly in section, and Fig. 2 a rear - end elevation of the arrangement. The trolley pole is mounted on a pivot a<1> carried by a standard b which can rotate on the vertical pivot b<1>. This standard b also carries a pin c, on which a collar e is fixed at one end, the other end passing through a plate hand the two limbs of the lever g and carrying a wheel t between these limbs. A spring d is fixed at one end in the sleeve e, the other end passing round the plate h and into the holes f in the lever g. A pawl p, pivoted at q, is pressed against, the wheel t by the spring r and connected to the rod v. The longer end of the lever g is connected to the rod m which, like the rod v, works loose in a projection from the trolley pole and carries a stop ring o. When the trolley wheel leaves the conductor, the stop ring x is knocked upwards, causing the pawl p to leave the tooth s, when the spring d forces the lever g in the direction of the arrow. During its motion, the nose y of the lever g presses against the projection z on the pawl, thus lowering the trolley pole. To re-set the mechanism, the trolley pole is pulled down so that the projection n acting against the stop ring o turns the lever g until the pawl catches in the tooth s, as before.
