Title: Improvements in the manufacture of non-woven webs
IPC: D04H3/07
Filed: 1959-01-20
Abstract: 843,087. Adhesively united thread fabrics; laminates; laminating apparatus. KIMBERLY-CLARK CORPORATION. Jan. 20, 1959 [Feb. 6, 1958], No. 2123/59. Class 140. A method of making a continuous non-woven web comprises superposing on a layer of strands a second layer the strands of which lie at a substantial angle to the strands of the first layer, cutting the web so formed along the length of the strands of the first layer so as to trim the strands of the second layer, and applying, before the trimming step, a third layer to the web comprising strands at least adjacent to the line of trimming to be effected. As shown (Fig. 1), a sheet 81 of non-woven fabric or other sheet material is guided on to the surface of a moving belt 83 by rollers 82, 84, whereafter it is overlaid with longitudinal threads 86 from a creel 87 which pass over comb 92 and are then coated with adhesive by applicator roll 93. The thread reinforced web and belt 83 carrying it are then guided about a stationary cylindrical mandrel 96 so as to form a helix thereon, the belt being pulled by means not shown. The mandrel (Fig. 2) has a helical spline 129 to guide the belt 83. Rotating carrier 97, mounted coaxially with the mandrel, applies threads 99 to the moving web in a direction normal to that of the previously applied threads 86. Just before or at the time belt 83 is removed from mandrel 96 a slitter 102 engages the web to sever the cross-threads 99 parallel to the marginal edge of the web. Threads 37 and 38 from spools 35 and 36, respectively, are fed through adhesive applicator 39 and thence are applied to opposite sides of, and close to, the longitudinal line along which cutter 102 will sever cross-threads 99 of web 110. Sheet 81 may be omitted, in which case threads 86 are supported directly by belt 83: alternatively belt 83 may be omitted, in which case sheet 81 serves as the support for threads 86. The thread-reinforced product 110 is separated from belt 83 (when this is used) which passes over rollers 103 and 104 while the product 110 passes about heated roller 106 in contact with heatresistant roller 107 to cause the adhesive applied to threads 86 to become more plastic and to flow about the junctions of threads 86 and 99. The product is then finally conveyed by roller 108 to slitting means 109 where it is cut to a desired width and wound about wind-up reel 111. Threads 37 and 38 may be trimmed away by slitting means 109. For threads 37 and 38 there may be substituted narrow tapes of suitable material. Specification 797,520 is referred to.

Title: Improvements in hat-shaping or blocking machines
IPC: A42C1/04
Filed: 1929-01-22
Abstract: 313,949. CassÚ, M. June 20, 1928. [Con. vention date]. Blocking; drying; softening; stretching in manufacture.-In a hat shaping machine, the collar 15 for forming the joint line with the brim is elastic and so shaped that its normal diameter is considerably larger than the block 4 but when in operation it contacts with the part of the hat backed by the brim plate 5 its diameter decreases to form the joint line. The block 4 and brim plate 5 are of perforated metal. The plate 5 forms the top of a chamber 6 supported by a tubular shaft 11 communicating with a vacuum chamber 12. A steam pipe 8 opens into the chamber 6. The collar 15 is elastic and normally of truncated conical form. The brim of the hat is held by spaced grippers 3. In operation, the work is positioned, the block 4 is raised and the collar 15 lowered as usual. The resistance of the hat causes the collar 15 to approach the form of a flat ring, its diameter decreasing, this deformation reaching a maximum as the collar 15 contacts with the part of the hat backed by the plate 5. Steam, meanwhile, percolates through the hat. When the shaping is complete, the steam is shut off and the valve 14 opened causing cold air to be drawn through the hat to dry the same.

Title: Improvements in or relating to ratchet gears
IPC: F16H29/02
Filed: 1929-01-22
Abstract: 328,233. Abbott, G. J. Jan. 22, 1929. Controlling variable-speed gearing.-A ratchet driving device comprises a toothed barrel or drum to which rotation is imparted by a pawl or pawls adapted to oscillate and at the same time to move axially in relation to the drum. The arrangement enables a prolonged drive to be effected before the pawl goes out of action by reaching a blank or non-toothed surface on the driven member, and is shown applied to control variable speed gearing of the expanding pulley type wherein it is desired to maintain a constant speed of the driven shaft notwithstanding fluctuations of speed of the driving shaft, as in driving a lighting dynamo from the track wheels of a railway vehicle. The expanding pulleys (not shown) are controlled in known manner by rotation of a screwed shaft C, the driven pulley being mounted on the shaft B. The ratchet drum D is secured on the shaft C and is preferably formed with teeth arranged helically, blank portions at each end of the drum preventing over-rotation of the shaft. The drum is driven in either direction as required, to correct the gear ratio, by pawls mounted in a frame comprising loose end plates E on the drum shaft connected by crossbars E<1>, E<2>, E<3>, the frame being maintained in constant oscillation by connection through a link H<6> to an eccentric H<4> on the boss of a gearwheel H<2> driven through gears H<1> from the driven shaft B. The pawls comprise oppositely directed elements G, G<1> rotatably mounted on a sleeve F slidable on a squared shaft E<4> which is rotatably mounted in the end plates E of the oscillatory frame, the sleeve F being formed with an outwardly directed flange F<2>, to which the tails of the pawls are connected by springs G<2>, and an inwardly directed flange or tongue F<1> which engages the helical groove between the teeth on the drum, thereby imparting axial travel to the pawl carrier as the drum is rotated. When the driven shaft B rotates at a predetermined normal speed, both pawls are out of action. If the speed departs from normal, the shaft E<4> is rocked to throw one or other of the pawls into action through the medium of a centrifugal governor J on an extension B<1> of the driven shaft B. The governor acts through a spring-pressed sleeve K, a grooved collar K<5> on which is engaged by forked arm L<1> on a rock shaft L coupled through a crank arm L<4> and link M<2> to an arm M on the shaft E<4>. At normal speed, when the pawls are out of action, the end M<1> of the arm M is concentric with the drum.

Title: A type printing telegraphic system
IPC: H04L19/00
Filed: 1936-01-29
Abstract: 469,662. Type printing telegraphy. LAUDANO, F. Jan. 29, 1936, No. 2609. [Class 40 (iii)] In a system of typeprinting telegraphy, actuation of one of the keys of the keyboard transmitter closes the line circuit and sets intc rotation synchronously moving members at both transmitter and receiver which are arrested by opening the line circuit after a displacement determined by the character to be transmitted ; the rotary member at the receiver is a typewheel and, after a printing movement, both members return to their initial positions in a reverse direction. As shown the rotary members 4 at the transmitter T and receiver R are turned anticlockwise by a spring-urged toothed sector 11 when the pawls 8 are withdrawn from the ratchet wheels 3 by the energization of the line magnets 13 when the line circuit a is closed by one of the character keys 15 which is held closed by a magnet 14 also in the line circuit. The line circuit is reopened at the transmitter when an insulating member 7 attached to a conducting disc 2, rotating with the member 4 reaches the brush 6 individual to the depressed key 15. The members 4 are arrested by the release of the pawls 8 which close the contacts 18 to energize the magnets 17 whose circuits have been prepared at the contacts 19 which close when the sectors 11 move from their position of rest. The magnets 17 reset the sectors 11 and thus return the rotary members to their initial position. For printing, a magnet 26 at the receiver is connected in parallel with the magnet 17 and operates a hammer 20 to raise the paper strip 23 against the type 2b carried by the member 2 rotated with the wheel 4. Pawls 24, 25 advance the tape 23 and ink ribbon 22 respectively. The speed of the rotary members is controlled by governors 12 which may be thrown out of action by a free wheel device during the return movement.

Filed: 1958-01-27
Abstract: 877,566. Moulding gear finishing tools. NATIONAL BROACH & MACHINE CO. Jan. 27, 1958 [March 18, 1957], No. 2620/58. Addition to 829,130. Class 87(2). A gear finishing tool, more especially a gearlike hone for use in finishing gears, is made according to the method claimed in the parent Specification, by forming a hollow gear-shape mould having an accuracy equal to that required in the tool and filling with a mixture of abrasive particles and a dimensionally stable uncured resin compound which is then cured. The mould is made, Fig. 2, by supporting a pilot 24 on a bottom plate 23 surrounded by a ring 26, positioning a master gear 32 on the pilot 24, resting upon top of the master gear 32 a cover plate 36 through which extends a plurality of openings 38, filling the space between the master gear 32 and the ring 26 with a resin compound which is then cured, and finally removing the master gear 32 to leave a hollow gear-like cavity in the mould in which stands the accurately centred pilot 24. An annular core body 16 of metal, e.g. cast iron or a suitable resin compound, is then mounted, Fig. 9, on the pilot 24, the cover plate 36 replaced, and one of the openings 38 in the plate connected to a source of plastic abrasive resin compound air being expelled through the remaining openings 38. As the resin reaches the openings 38 adjacent the one being supplied, it commences to flow out of these openings at which instant suitable plugs are inserted and this operation is continued until the mould cavity is full. Epoxy resins are the most suitable, in particular when compounded with equal parts by weight of powdered silica. Tools in the form of internal cylindrical gears and bevel shaped gears, as well as external cylindrical gears, can be made by the method of this invention. Specification 800,680 also is referred to.

An irrigating device comprises a spraying element 3, having closely spaced and relatively widely divergent apertures 7, which oscillates about a shaft 2 carried on the forked end of a standard 1. The'element 3, having a water inlet 4, is driven by a double-acting piston 15 which is connected by a piston rod 12, comprising coaxially disposed tubes 17, 18, to a valve housing 11. A rod 9, adjustably secured against the shaft 2, is connected to the valve housing. The annuler space between tubes 17 and 18 is connected by an aperture 19 to the space above the piston, and the lower end of the inner tube to the space below. Valve housing 11 has a water inlet 26 fed from a flexible hose 28, and an outlet 250 connected by a flexible tube 251 to an outlet nipple 252. An oscillating plug 23 within housing 11 allows the supply of water alternately to the upper and lower spaces of the cylinder 14, the water in the space below the piston being exhausted through the outlet nipple 252 when the space above the piston is being supplied and vice-versa. The plug 23, secured to an arm 30, is rapidly moved from one position to the other when the piston reaches the end of its stroke, by projections 33 on a lever 34 pivoted on housing 11 at 35, and operated by two stops 36 on a fixed rod 37. The angle through which the element 3 is swung is varied by adjusting the lower stop 36, and its angle to the vertical at the start of a stroke adjusted by adjusting the rod 9 about the shaft 2. Reference has been directed by the Comptroller to Specification 632,140.
