Abstract: 231,100. Baker, C. A. Oct. 30, 1924. Reels and winches, rod.-In reels for fishing rods of the kind which are provided with variablespeed winding mechanisms, the reel shaft 2 is mounted in a gear box 3 and carries a slidable member 25 with gears 5, 6 which engage gears 17, 18 respectively on the driving spindle 7. The lateral movement of the member 25 is obtained by a. bar 27 engaging a groove 26 therein and movable against a compression spring by a cam member 32 actuated by a link 35 and finger-piece 39, means for indicating the position of the gears and retaining them in their adjusted position preferably being provided on the gear box. The gears 17, 18 are connected to the spindle 7 by a friction clutch consisting of a leather washer 19, a metal washer 20 and screw adjustment 14. A ratchet wheel 22 engages a spring pawl to prevent the spindle running back. The outer end of the reel shaft is mounted in a shallow box 44 on which is carried an adjustable click 51 engaging a serrated wheel on the reel.

Title: Improvements in and relating to shuttles of looms for weaving
IPC: D03J5/00
Filed: 1921-09-30
Abstract: 189,592. Wright, C. S. Sept. 30, 1921. Shuttles; Shuttles, changing bobbins in, automatically.-Relates to shuttles having a bobbinreceiving recess and a forked bobbin-holding spring of which the upper edges 11 of the arms are bevelled and are slightly below the top of the shuttle 1, and consists in making the vertical dimension of the arms 6 greater than the diameter of the heel of the bobbin 3. The shoulder 12 formed by the bevelled edge 11 of each arm is considerably above the notches 7 which receive the rings on the heel, and is spaced from the bottom of the arm by a distance at least equal to the diameter of the heel, so that when a bobbin has been introduced, it will have its diameter carried below the ridges before the spent bobbin has been ejected, the resiliency of the arms forcing the heel into the notches, thereby shortening the stroke of the transferrer 9. The guidemember 15 is curved at 16 to guide the bobbin easily into position.

Title: Improved means and process for producing balls, rollers and other articles from bars or rods
IPC: B21H1/14
Filed: 1935-09-21
Abstract: 443,418. Rolling balls &c. BRITISH TIMKEN, Ltd., and ELLIS, L. M., Cheston Road, Aston, Birmingham. Sept. 21, 1935, No. 26195. [Classes 83 (ii) and 83 (iv)] Balls, rollers, or other profiled articles are made from a rod fed axially between a pair of conical rolls 1, with inclined axes, forming a tapering pass, one or both rolls having grooves 4, and ribs 3 of gradually increasing depth and sharpness which gradually groove the rod deeper until each ball is twisted off therefrom by the greater peripheral speed of the larger end of the roll. A peg 23 in one roll engages and discharges the balls from the pass as they are formed and they are free to fall through the cut away end of guides (not shown). Fig. 5 shows a mill for making rollers for roller bearings in which the top grooved roll 1 forms a pass with a pair of bottom rolls 1<a>, the spiral rib 3 of the top roll being of gradually increasing depth. The pass can be adjusted by distance washers 19 which locate the tapered roll shell along its inclined shaft 5 as required.
Patent GB-1220163-A (GB)
Title: Mechanical-pneumatic servo control system for high speed impact devices
IPC: B21J7/24
Filed: 1968-05-31
Abstract: 1,220,163. Pneumatic hammer. CHAMBERSBURG ENG. CO. 31 May, 1968 [12 June, 1967], No. 26202/68. Heading B3H. A pneumatic hammer for use with compressed air or other gaseous medium has a ram 22 connected to and driven by a piston 18 reciprocable in a cylinder 16 and the air or gas supply above the piston is controlled by pneumatically operated inlet 70 and exhaust valves 40 operated by air or gas from the supply through a pilot spool valve 130. A throttle valve is provided in the inlet passage and operated by a treadle 14 through linkage 112, 106. The ram is guided in the frame 12 by four guides 24 and the cylinder 16 and fluid passages provided in the yoke 14 bolted to the frame. A gas reservoir 30 is provided in the yoke and the gas is pressured from a regulating valve 38. A passage 32 leads to the cylinder so that the pressurized gas raises the piston when the upper part is exhausted. The exhaust duct 42 of the upper part extends through the reservoir so that the exhaust gases cooled by sudden expansion are heated by the pressurized gas heated by friction when passed through the passage 32. This prevents icing of the exhaust valve. The exhaust valve, Fig. 7 (not shown), is spring biased open and closed by compressed gas from the spool valve to move a cup-shaped closure member (54) against a valve seat (50). The inlet valve, Fig. 9 (not shown), is of the poppet-valve type (74) and spring biased closed and opened by compressed gas from the spool valve which moves a cup (82) to displace the valve stem (76). A footoperated throttle valve is positioned upstream from the inlet valve and comprises an apertured sleeve (102), Fig. 5 (not shown), rotatable in a bore normal to the inlet passage (98). The sleeve is rotated by a lever 106 and spring biased into the closed position. The pressure supplied to the upper part of the cylinder is greater than the pressure in the reservoir so that when the exhaust valve is closed and the inlet valve opened the ram is caused to descend. A relief valve is provided in the exhaust duct 42 to prevent build up of pressure above the piston on the return stroke. An inlet port by-pass passage (122), Fig. 4 (not shown), is provided in the yoke 14 to a normally closed relief valve 120. This passage allows the air pressure to be applied above the piston when the inlet port is blocked by the piston. The spool valve, Figs. 10A, 10B, 10C, 10D, 10E (not shown), is moved by a lever linkage 146, 152 pivoted at 154 and operated by a cam follower 150 running on a cam 156 on the ram. The size of the impact can be controlled by the degree of opening of the throttle valve and if the valve is kept open by the operator the hammer will automatically recycle. A single blow may be effected by a quick depression of the treadle 114. Specification 1,220,164 claims a pneumatic hammer of the above type in which the exhaust gases are heated by heat-exchange with the gas in the reservoir to prevent frosting of the exhaust valve.

Pleating head 71 is fixed to one of a series of radially-disposed mounting blocks 67 bolted to a platform 65 and is fixed relative to the shaft 64. Head 70 is pivoted on an arm 73 extending from block 67. The sealing jaws 82, 83 are mounted alongside the pleating heads and have heating elements 90, 91 adjacent their sealing surfaces 92, 93 for sealing the tubular material after its passagethrough the pleating heads. The action of both the pleating heads and the sealing jaws are effected by piston-cylinder arrangements driven by air coming from shaft 64 via valves 103, 106 to one or the other end of cylinders 74, 95, thus driving the pistons. The continuous length of flexible tubing coated with stripes of adhesive at positions intended for sealing is produced from a web 14, (Fig. 1) of material supplied from a roll 13.
