Abstract

Fig. 1 illustrates a prior art right-angle attachment for a dial indicator, to allow measurement by the dial indicator in an axis perpendicular to the axis of the indicator follower. Forces out-of-line will have a tendency to deflect the dial indicator mounting bracket 10, or cause misalignment of the right-angle bracket 12 with the dial indicator follower 14. Forces in-line will cause the attachment to function properly as will a force which is nearly in-line.

Device for Transmitting Radial Force into In Line Force

Fig. 1 illustrates a prior art right-angle attachment for a dial indicator, to allow measurement by the dial indicator in an axis perpendicular to the axis of the indicator follower. Forces out-of-line will have a tendency to deflect the dial indicator mounting bracket 10, or cause misalignment of the right-angle bracket 12 with the dial indicator follower 14. Forces in-line will cause the attachment to function properly as will a force which is nearly in-line.

To overcome damage to the dial indicator 20 and allow measurement at a right angle to the axis of the dial indicator follower, a rigid support member 16 is attached to the housing 18 of dial indicator 20 in Fig. 2. The rigid support member 16 has a channel 22 formed therein to contain balls, such as ball bearings 24.

Retainer strip 26 attaches to support member 16 to retain balls 24 within channel 22. The device is calibrated such that the deflection of any work piece or force exerted, such as indicated by the arrow in Fig. 2, will be transmitted through the balls in the channel 22 and displace the dial indicator follower 14 rendering a reading.
