摘要： 184,298. Evans, H. L. May 25, 1921. Sashes balanced one against another.-Relates to windows of the type in which the sashes are 'balanced one against another by means of wheels gearing into racks, secured to the sashes, and consists in constructing the wheel-gear chamber in the fixed frame with an upper partition e , a lower partition f , and a removable door l , as shown in Fig. 2. The ordinary type of window having duplexshoots can be adapted for this mechanism bv first cutting away the parting bead d and forming the chamber as shown in Fig. 1. The gear-wheels are formed of three ply metal.

摘要： 291,663. Evans, R. E. L., Evans, R. Y. K. N., and Evans, D. K. L. N. Oct. 5, 1927. Castors.-A cylindrical peg e to receive a sucketted castor c is permanently secured to the leg f of a metal article of furniture, and is of substantially the same diameter as the leg. The castor socket comprises a tube a rigid with the yoke and provided at its lower end with a seating d to engage the peg. The latter may be a piece of rod, chilled in, or a tube with a plugged end, Fig. 4, fitted over the leg of the article. Specification 18783/94 is referred to.

摘要： 561,317. Locking levers &c. EVANS, A. H. L. Jan. 26, 1943, No. 1276. [Class 80 (iii)] A self-locking coupling for use in operating gear for sliding windows or the like comprises a fixed cylindrical casing 10 receiving a driving member having a handle engaging portion 18, a bearing journal' 12, a flange 19 and axially extending lugs 24. The latter co-operate with loose segmental plates 26 having a curved surface engageable with the inner surface of the casing 10. A spring 21 fixed in a groove in the flange 19 has dragging effect on the casing. The driven member comprises a pinion 29, for engagement with a rack on the window, and a cam 31 approximately elliptical with flats 32. The cam 31 engages between the plates 26. A pin 36 centres the driving and driven members. Rotation of the driving member will cause rotation of the driven member by engagement of the lugs 24 with the plates 26. Should the driving member be stationary and the driven member be turned, then the cam 31 will cause axial separation of the plates 26 and these will frictionally grip the casing 10 and locking will result.

摘要： 392,981. Drum controllers. EVANS, R. M. L., Roselands, Harboro' Road, Ashton-on- Mersey, and ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Crown House, Aldwych, London. Dec. 2, 1931, No. 33426. [Class 38 (iii).] A controller comprises a main drum 1 actuable to various positions on either side of a zero by a handle 21, and retained in such positions by a notched plate 22, which may be devoid of notches at the two extreme positions, so that the drum is returned to an intermediate position by a spring 35 when the handle 21 is released from an extreme position. An auxiliary drum 2 is urged away from its zero position by a weighted lever 62, but is restrained from movement by a roller 71 thereon engaging a cam 70 of the drum 1, until the drum 1 is displaced, and is returned to zero when the drum 1 is returned to zero. The speed of movement of the drum 2 is limited by a pendulum escapement device 82, 86. Movement of drum 2 from its zero position can be prevented by a coil 100 energized by the back E.M.F. of the motor, so that upon sudden reversal of the drum 1, the drum 2 cannot move from its zero position until the motor has slowed down sufficiently. The drum 1 may prepare the armature and field circuits and effect release of a brake, and the drum 2 may connect the circuits to the power supply, exclude resistance, and in the extreme positions cause field weakening.

摘要： A tool bit holder that accommodates and secures specific ranges of hexagonal wrench sizes in different physical orientations therein, for four purposes: speed rotation of the tool for fast bolt extraction, support of the hexagonal wrench's shaft for an increased torque application, mechanically strengthening of a hexagonal wrench, and for the application of torque centered about the longitudinal axis of the working arm of the hexagonal tool bit so as to prevent the stripping out of the hexagonal socket in the mechanical fastener.
