Title: Crutches
IPC: A61H3/04
Abstract: 135,040. Spielmann, Sir I. Jan. 18, 1919. Crutches.-Comprises a special construction of wheeled crutch apparatus or walking-machine for invalids, of the kind in which a pair of crutches are mounted on a wheeled base frame so as to be adjustable in height, inclination, and distance apart. The special features of the present construction consist in (1) the provision of a base frame comprising four members rigidly or detachably connected together and arranged so as to be no higher from the ground than the tops of the small supporting wheels, (2) in the mounting of the crutch members upon side frames supported directly on the members of the base frame, and (3) by preference, arranging the side members and the base frame to fold up flat when not in use, to minimize storage space. The apparatus comprises a three-wheeled base comprising four members a, a<1> which may be connected rigidly, but are preferably connected detachably as shown by means of the double-eyed screw clamps b. Similar clamps h permit of the side frames f being adjusted laterally or angularly on the base members a. The side frames carry adjustable hand rests l and telescopically mounted crutch heads k. By slackening the nuts h<1>, the two side frames can be folded substantially into the plane of the base plate so that the whole apparatus can be laid flat against a wall for storage purposes. Detachable cross stays may be fitted between the side frames if desirable, and one end member a<1> of the base frame may be made readily removable to avoid the user having to step over it when entering the machine,

Abstract: 1,120,941. Variable-pitch marine propellers. YARROW & CO. 8 July, 1965 [8 April, 1964], No. 14529/64. Heading B7V. In a ship, means are provided for controlling the pitch of at least two variable-pitch propellers 12, 18, Fig. 1, in relation to the angular position of a rudder means in such a manner as to prevent the propellers opposing the steering action of the rudder means. The propellers may be driven by either a main prime-mover 1, e.g. a diesel engine, or a subsidiary primemover 2, e.g. a gas-turbine engine, through a clutch 3 or 5, and a gear train 6-10 and 13-16, the clutches being arranged so as to prevent engagement of both of them simultaneously. Alternatively, the propellers may be driven by either one or both of two main prime-movers (19, 20), Fig. 3 (not shown), or a subsidiary prime-mover 2, through a corresponding clutch, or clutches, 5 (23 and/or 28) and a gear train 10, 16 (20, 21, 22, 24, 25, 30, 32). The ship may be furnished with three prime-movers, e.g. gasturbine engines, which may be identical to one another, clutches associated therewith being arranged such that the propellers can be driven by any combination of the prime-movers through a suitable gear train. The means aforesaid for controlling the pitch of the propellers 12, 18 or that of two similar propellers 33, 34, Fig. 5, may comprise slidable members, or slides, 43, 51 coupled by levers 42, 50 to pitch-control boxes 41, 49 on a pair of propeller-shafts 35, 36, said slides being mounted on plungers 44, 52 that are lodged in cylinders 47, 54 hydraulically or pneumatically connected to a bridge control 48 for regulating the pitch of the propellers independently of each other. When a pair of rudders 40 are angularly displaced from a fore-and-aft position in one direction or the other, one of two cams 56, 57 attached to a rudder-coupling bar or tiller link 55 depresses a plunger 56a or 57a, that is lodged in a cylinder 56b or 57b, hydraulically or pneumatically connected to a plunger 60 or 61, which engages with the lever 42 or 50, adjacent thereto, whereby the pitch of the associated propeller is reduced sufficiently to prevent the propellers opposing the steering action of the rudders. Alternatively, the levers 42, 50 carry slides (62, 64), Fig. 6 (not shown), which are coupled to the plungers 44, 61 and 53, 60, respectively. As shown, the propellers 33, 34 are driven by a single prime-mover 38 through a clutch 39 and a gear-box 37. The connections between the various plungers and the control 48 may be electrical instead of hydraulic or pneumatic. Any of the prime-movers may be constituted by a steam-turbine engine or a reciprocating- piston steam engine, or may be replaced by an electric motor.

Abstract: 378,945. Sole-trimming machines. BRITISH UNITED SHOE MACHINERY CO., Ltd. and HALLAM, H., Union Works, Belgrave Road, Leicester. May 20, 1931, No. 14854. [Class 60.] Guides and rests ; gauges ; trueing rotating tools.-In a machine for bevelling the edges of soles, particularly the heel edges of reinforced loose insoles, the sole is moved substantially parallel to the axis of a grinding-wheel while maintained in a position non-radial to the wheel by guiding means which may be adjusted to vary the angle of the bevel produced on the sole. The shaft 5, mounted in a head 3 is rotated at approximately 2500 r.p.m. and carries a grinding-wheel 7 which is about 7 inches in diameter and ¥ inch wide, preferably of soft composition. A bracket 9 carries a circular dust-collecting hood 11 enclosing the wheel and provided with an opening 83 connected to the exhaust passage 87 leading from the hood. The spring 83 is closed by a butterfly valve 89 which may be opened periodically by the operator to allow the suction to draw away accumulations of dust. A stationary sleeve 13 enclosing the grinding-spindle carries a bracket 17 having a guide rib over which moves a slide 21. The slide is adjusted along its guide by a threaded spindle 29 operated from a hand-wheel 31 and is clamped in position by a bolt 25. The forward end of the slide has an arcuate guideway 37 along which is adjustable a block 39 carrying a bifurcated member 41 which straddles the grinding-wheel and which carries, on a pivot 45, the spring-urged work support 43. The member 41 also carries an adjustable work-positioning foot 51 and the work, shown as a reinforced insole, is held between this foot and the work support 43. An edge gauge comprising a blade 53 is secured to the rear of the foot and is arranged to project about 1/32 inch from the lower surface of the foot to a position closely adjacent the grinding-wheel. The guideway 37 is concentric with the lower edge of the gauge and the adjustment is such that the angle of the bevel may be varied between 11‹ and 31‹. The screw spindle 29 serves to adjust the workguiding mechanism as the grinding-wheel wears away. A dressing-wheel 55 comprising a number of corrugated steel discs mounted on a pin 57 is carried on a link 59 and may be brought into operation by means of a hand-lever 65 which is moved against a spring 73 which normally raises the dressing-wheel clear of the grinding-wheel. To allow access to the wheel one side of the hood is formed as a door 77 pivoted on a pin 79 and secured in the closed position by a screw 81.
