Abstract: 631,806. Knitting. JASKA, Ltd., and HUNT, J. V. E. Oct, 8, 1946, No. 30008. [Class 74 (ii)] A knitted fabric has two yarns laid in and interlooped, but not knitted, at each course or spaced courses of the fabric. The yarns are interlooped at desired wales and may each be interlooped in different wales in the same course as well as being interlooped in different wales in different courses. As described, two yarns y<SP>1</SP>, y<SP>2</SP> are interlooped at adjacent wales B, C and D, E in every course 1, 2, 3, 4 of a plain fabric and are interlooped at every fourth wale in a course and in the same wale every alternate course. Alternatively a course or courses having only one yarn interlooped may be spaced between courses having two yarns laid in. The fabric is produced on a circular loopwheel machine, provided, as described, with four feeders between which are positioned single, obliquely disposed, yarn laying-in wheels. For laying in two yarns at selected courses, one or two of the feeders are rendered inoperative or an additional yarn laying-in wheel is associated with each of the existing yarn laying-in wheels.

A dispensing stopper 7 of resilient plastics has an internal screw-thread 10 which is engaged with a screw-thread 3 around the neck 2 of a resilient plastics container 1, a lower broadened portion 11 of the stopper skirt 9 having an inwardly-directed stop lug (12), Figs. 2, 3 (not shown), which on initially screwing the stopper on to the neck is forced over an outwardly projecting stop lug 4, Fig. 1, at the base of the neck. The stopper 7 can then be further turned to screw it fully home; the amount the stopper can later be unscrewed is limited by engagement of the stop lugs 4, (12). A dispensing port 13 is provided in the stopper skirt 9, and a ring-shaped sealing lip 16 within the stopper top 8. In the form shown, when the stopper 7 is unscrewed as far as the lugs 4, (12) will permit, the port 13 is raised above the mouth of the container neck 2, and liquid within the container can be dispensed through the port. When the stopper 7 is screwed home, the port 13 is below the mouth of the container neck 2, and a raised bead (15), Fig. 5 (not shown), around its inner end, is seated firmly against the outer face of the bottle neck; at the same time, the sealing lip 16 is engaged with the mouth of the container. As illustrated, the port 13 projects radially through a projection 16 on the stopper skirt 9; in one modification, the port (18), Fig. 6 (not shown), projects axially through the skirt to a projection (19) on the stopper top (8). In another modification, when the stopper (29), Fig. 7 (not shown), is unscrewed to its open position, the port (35) in the stopper skirt (31) is aligned with a port (27) extending radially through the container neck (26).

Time recording mechanism for a ticket cancelling machine comprises a clock motor driving a cam member to operate a switch in the circuit of a solenoid for driving time print wheels, and percussion means controlled by the insertion of a ticket to effect printing of the time on the ticket. The machine described is similar to that of Specification 1,065,764. A clock motor 23 drives a cam 24 which changes over a two-way switch 25 four times each revolution. At each changeover a circuit is completed through one of two alternative branch circuits to a solenoid 26 which operates through a claw member 27 to step on the lowest order time printing wheel 6. Also, through a further claw 54 and ratchet wheel 55 a second cam 56 is stepped on and changes over a second two-way switch 57 to prepare the other branch of the circuit for the next changeover of switch 25. A further two-way switch 50 in the circuit of solenoid 26 is controlled by a member (49, Fig. 3, not shown) on the guillotine operating link and prevents operation of solenoid 26 while a ticket is being printed.

Pistons. - In a piston comprising a cast head and a wrought-metal skirt, the latter is formed with an intermediate attachment flange engaging a concentric shoulder on the head and carries a scraper or other ring adjacent the attachment. The skirt 2, Fig. 1, may be turned from the solid, the flange 3 being secured to a seating 6 by studs 5 and engaging a shoulder 15 in the head. The seating 6 is formed partly in the gudgeon-pin bosses and partly on a ring connecting the bosses which ring may be divided or unbroken.

The outer part of the groove is left unflattened to accommodate a scraper ring, and the shoulder thus formed engages a shoulder on the head, as shown. In a two part skirt the parts may be spaced by a ring 19, Fig. 3, forming a scraperring groove and provided with draining channels 20, 21. Alternatively, the parts of the skirt may be spaced by folding the flange of one or both parts. The spacing-ring may be replaced by tongues 30, Fig. 7, turned up from the bottom or sides of a groove in a one-piece skirt, or in the sides of a groove formed between the parts of a two-piece skirt. The skirt may be secured by a clamping ring 28. Specification 286,867 is referred to.

Title: An improved method of planing helical teeth, more particularly for bevel gears
IPC: B23F1/04
Filed: 1920-10-27
Abstract: 153,026. Brandenberger, H. May 2, 1919, [Convention date]. Gear-cutting; tools.-Helical bevels are generated by a process in which the cutting-edge of a tool working in a straight line towards the apex of the pitch cone of the rotating blank is inclined to the line of cut and is perpendicular to the straight lines on the pitch plane along which the tool moves towards the cone apex. Any suitable mechanism may be used to give the required rolling motion to the blank in addition to the motion producing the helical formation of the teeth. In Fig. 5, s represents the apex of the pitch cone, and the dotted line x-y shows the intersection with a tooth flank of the pitch plane of the crown gear imagined to be in contact with the pitch cone. The cutting-edge 13 of the tool is at right-angles to the line O-S. Thus, during the rolling of the cone on the plane of the imaginary crown wheel, the whole of the flank 5 in a plane at right-angles to a generator is cut with the same disposition of the cutting-tool so that teeth of theoretical accuracy may be cut. Figs. 7, 8, and 9 show one form of tool operating in accordance with the invention, the cutting-edge 9 being inclined to the line of cut 10 and at rightangles to the line of motion 11 of the tool. The edges of the prism are inclined at an angle # to the crown wheel plane 2<1> and at an angle e to the line of motion of the tool so that a clearance angle # to the line of cut is obtained. To cut gears of different root angles, the position of the cutting-edge of the tool is re-set by altering the angle #, this adjustment being subject to the condition that a clearance angle # must always exist.
