Abstract: 1,157,264. Measuring speed and torque electrically. SUN ELECTRIC CORP. July 5, 1966 (July 16, 1965], No.30203/65. Heading G1N. A vehicle test bed has two rollers 13, Fig.2, on a shaft carrying an eddy current brake 20, and two rollers 14 mounted on a second shaft carrying a tachogenerator 18, a vehicle under test being arranged with one driving wheel engaging one roller 13 and one roller 14, and the other driving wheel engaging the second roller 13 and the second roller 14, the output of the tachogenerator being compared with a signal preset on a potentiometer 24 to represent a desired speed, and the brake being operated when the actual speed exceeds the desired speed so as to maintain the desired speed. The brake 20 is resiliently mounted and carries an arm (21, Fig. 1, not shown) which moves a potentiometer tapping 22 by an amount proportional to the torque developed, this being indicated on a meter 26. The test is carried out with the throttle of the vehicle fully open. A second meter 27 is connected across the tachogenerator to measure actual speed. In a second arrangement (not shown), a predetermined torque is set on a dial 30 and a corresponding electrical signal is developed and compared with the measured torque signal from the tapping 22, any positive difference being used to operate the brake to thereby maintain a constant torque. This enables simulated acceleration tests, etc., at constant torque to be carried out, the speed being measured at 27. The presetting controls 24, 30 are mounted with an amplifier 25 in a remote unit placeable within the vehicle, and a manual override may be provided for braking the vehicle. Cooling fans for the brake are provided (28, Fig. 1, not shown) and disc brakes (29) serve to retain the rollers while the vehicle is driven on to them.

Title: Safety devices for power tools

Filed: 1976-07-22
Abstract: 1536595 Clutches; controlling clutches; safety devices TEXTRON Inc 22 July 1976 [25 July 1975 (2)] 30519/76 Headings F2C F2J and F2L A safety device for inclusion in a power saw, comprises a releasable coupling connecting a centrifugal clutch and a power source to cutting means, the coupling being so arranged that, upon the occurrence of a kick-back during use of the saw, the centrifugal clutch is disengaged from the cutting means. The centrifugal clutch may comprise spring mounted shoes (6b) (Fig. 4, not shown) attached to a driving shaft 1 and engageable, by the action of centrifugal force, with a rotatable drum (5), auxiliary shoes (11) being provided for driving engagement of the drum (5) at low rotational speeds of the shaft (1). The drum (5) is attached to dished member (16) (Fig. 3, not shown) of the releasable coupling. The member (16) pivotally supports an annular pawl 17a having a nose portion 17d for engagement with abutments 15 on a member (14) fixed to a sprocket (2) which drives the cutting chain of the saw. The pawl 17a is urged by a spring 19 towards a position of engagement with one of the abutments 15 but by the action of centrifugal force it is urged to a position of disengagement, the latter being prevented during normal running by a pivotal latch 20. When during use, the saw kicks back, a safety guard 38 tilts (leftwards as seen in Fig. 1) and this causes rotation about their pivots of members 30, 33. As a consequence, a helical brake band 27 trained around a drum 26 attached to the sprocket is tightened to provide a braking effect on the sprocket (2) and simultaneously a nose portion of the member 33 pivots the latch 20 so as to free the pawl 17a and permit it, under the action of centrifugal force, to disengage from the abutments 15. Upon manually displacing the guard 38 back to its normal position, the brake is released and a second pivoted latch 23 is tilted by a further nose portion of the member 33 to permit the pawl to re-engage with the abutments 15 and thereafter resume drive from the centrifugal clutch to the cutting chain.
