Filed: 1936-03-13
Abstract: 461,466. Ice-making. ELECTROLUX, Ltd. March 13, 1936, No. 7643. Convention date, March 14, 1935. [Class 29] A metal ice tray is provided with a handle 19 mounted upon a fixed or rotatable shaft 22 supported in a sleeve formed by turning over the front edge of the tray, said handle having lugs 21 adapted, upon pulling the handle, to abut against fixed stops 23 on the tray compartment and so release the tray. By pressing the handle inwards, the lugs 21, or projections 24, Fig. 7, thereon, effect the release of the cube-forming grid in the tray by contact with a cross-bar 18 secured to the grid. In a modification, handles 19, 25, Fig. 8, are provided at opposite ends of the tray for releasing the tray and the grid respectively. Fig. 10 shows a metal grid formed of strips 35 carrying ribs 36 and secured to an insert 30 shaped to the front of the tray and having a ledge 31 against which the handle lugs abut. The grid may be formed by bending a strip of metal substantially to the form shown in Fig. 10, or by securing together a series of units 40, Fig. 11. Further, the grid may comprise a U-shaped strip 35, Fig. 13, having ribs 36, Fig. 16, secured thereto. In another arrangement, the grid consists of strips 48, Fig. 17, secured to end-plates 30, 50 and having ribs 36, Fig. 20.

Sewing-machines; governing needle thread.- In a buttonhole sewing-machine having a needle which co-operates in successive reciprocations with a threaded and a non-threaded looper respectively, take-up mechanism is provided which acts differently up on the needle thread at alternate reciprocations. The shaft 8 driven by the main shaft 5 which operates the threaded looper 28 and the non-threaded looper 29 carried by the rotary turret 32, drives the needle-actuating shaft 14 at twice the speed of the shaft 5 through bevel-wheels 10, 12. Surrounding theshaft 14 is a sleeve 15 which is driven by bevelwheels 11, 13 at half the speed of the shaft 14. The take-up mechanism comprises a pair of camdisks 37 on the sleeve 15 co-operating with a pair of arms 40 and a plate 41, the arms and plate being pivoted at 38 to allcw them to be turned up for threading. The cam-surfaces a, b, c, Fig. 8, acting on the thread in co-operation with the non-threaded looper, pull off more thread than the surfaces a, d, b co-operating with the threaded looper. A pin 48 operatirg a thread lock is actuacted by a lever and a cam 44 on the sleeve 15. Needles, vibrating laterally.-A switch lever pivoted in the machine head has a fork 24, Fig. 4, adapted to engage a pin 25 on a link 26 fulcrummed on the needle bar yoke and is oscillated, when the needle is at the top of its stroke and the pin engaged by the fork, to jog the needle laterally. A pin 27 engaging a slot in the needle block 22 is adjustable along a slot in the link 26, whereby the extent of lateral vibration imparted to the needle may be varied.

Title: Processes of preparing allylic substituted 9-fluorenecarboxylic acids
IPC: C07C61/39
Filed: 1950-03-31
Abstract: 9 - Allyl - 9 - fluorenecarboxylic acid is prepared by reacting allyl-9-fluorene carboxylate with a basic reagent capable of converting the ester to an anion capable of spontaneous rearrangement.  The preferred basic agent is lithium amide but active metal hydrides, active metal alkoxides or Grignard reagents may be used.  The reaction is preferably carried out under anhydrous conditions in a solvent such as ethers, dioxane, and hydrocarbons. In an example 9-fluorene carboxylic acid is made by treating benzilic acid in benzene solution with anhydrous aluminium chloride, separated, and esterified with allyl alcohol. The allyl-9-fluorene-carboxylate so obtained is treated with lithium amide in toluene solution to form the 9-allyl-9-fluorene-carboxylic acid.

IPC: F16K3/02
Filed: 1917-06-07
Abstract: 111,437. Bence, E. H. June 7, 1917. Stop vaioes; closure members. -A penstock or sluice valve has a valve member adapted to be moved first parallel to its seat and afterwards turned away at right-angles. In the form shown in the Fig., the valve member 4 is hinged by lugs 5 to a screwed actuating spindle 7 which passes through a boss 8 on the casing and is engaged by a hand-wheel 9. The initial movement of the screw slides the valve member upwards to disengage the wedges 12 and slightly open the valve, while a continued movement brings cams 10 on the valve member into contact with abutments 11 to turn the member away from its seat. The cams on the valve may be replaced by pins working in fixed cam grooves. The wedges 12 may be dispensed with, and means other than a screw may be used to actuate the valve.

Title: Improvements in or relating to Lasting Machines.
IPC: A43D21/02
Filed: 1917-10-16
Abstract: 122,349. British United Shoe Machinery Co., (United Shoe Machinery Co.). Oct. 16, 1917. Lasting.-A lasting-machine, such as is described in Specification 14453/97, is provided with means which ensure that, when the machine is stopped, the gripper will be left open. In one construction, Figs. 1 and 2, a brake 12 adapted to engage the inside rim of the usual pulley 6 on the cam shaft 5 is mounted on a pivoted lever 15, which is normally upheld by a spring 13 and has slidably mounted in it a spring-pressed plate 26 arranged to co-operate with a block 25 adjustably secured to a member on a spring-encircled stem 23 passing through a bore in a slide 22. This slide, which is guided in the machine frame, carries a roll 21 and is forced upwards by a spring 19 to maintain the roll in engagement with a cam 20 on the shaft 5. When the treadle of the machine is depressed, the upper wedge-shaped end of a rod 10 is withdrawn from engagement with the plate 26, which is then moved by its spring beneath the block 25. The cam 20 has one high brake-setting point corresponding to the open position of the gripper, and when this engages the roll 21, the block 25, through the plate 26, depresses the lever 15 and applies the brake. In another construction, Fig. 5, the upper end of the rod 10 is adapted to engage a roll 11 on a strap 17 surrounding an eccentric 40 on the shaft 5. This strap carries a radiallymovable detent block 14 backed by a stiff spring 38 and adapted to co-operate with a finely adjustable plate 42 secured to a lever 44, which is pivoted at 46 on a bracket 48 attached to the machine frame. The lever 44 pivotally carries a leather &c. lined brake shoe 54, which is provided with an extension 56 having an opening 57 tn receive loosely a pin 58 fixed in the bracket 48 by a set-screw 59. A tension spring 62 is arranged between the pin 58 and a second pin 60, and adjustable stop screws 64 are provided to engage the pin 58 to determine the position of the brake shoe when released. When the starting treadle of the machine is depressed, the rod 10 is raised and the strap 17 swung to cause the detent block 14 to slide off the plate 42, whereupon the brake shoe 54 is lifted clear of the pulley 6 by its spring 62. When the treadle is released, the block 14 swings by gravity until it meets the plate 42, and, as the block is moved in and out by the eccentric 40, it first clears and then moves downward on to the plate; swings the lever 44, and applies the brake. Specification 122,211 also is referred to.
