Anderson, Oak Park, 111., assignor to American Telephone and Telegraph Company, a corporation of New York Application May 17, 1932, Serial No. 611,908 1 Claim. 74112) This invention relates to measuring devices shaft 2 is adapted to be rotated continuously at and more particularly to registers for measuring a constant speed, for example, by means of a the elapsed time of telephone conversations. synchronous motor.

As shown in Figs. 1-7, the apparatus consists" which is pivoted at 2| to the bottom of the case, in general of a case I, a driving shaft 2, a drivand a peculiarly shaped spring 22.

released spring 1, and a reset spring 8. Driving Spring 22 is shaped more or less like a horse 60 shoe. One end of said spring is fastened to shifting fork 20 and the other end rests against the opposite side of the case. The position of this spring, with respect to the other parts of the register, is, shown in Figs. 1,2 and 3. Near its curved part this spring is bent inwardly to form flange 24.
Clutch control means 6 is T-shaped with one end of the top member being bent upward, as shown at 25 in Fig. 1. The vertical member extends downwardly through a slot in-case l and is pivoted to the sides of the case at 26. The lower part 21 of the vertical member is cylindrically shaped and is positioned within the curved part of clutch spring 22, as shown in Fig. 1.
Control or release spring 1 is positioned beneath the dial wheel assembly and the clutch control means, one end thereof being fastened to the bottom of the case. At one point on said spring a part thereof is bent upward to form flange 28. At another point thereon a part thereof is bent upward to form flange 29. The free end of said spring is bent upward to form a third flange 30. Flange serves as a holding means for clutch control means 6, flange 29 I serves as a stop for the dial wheel assembly when it is being reset and flange 28 when pressed down by tripping member 3|, which is fastened to the periphery of the dial wheel member, causes the release of the clutch control means 6.
The reset means consists of coil spring 8 wound around hub 32 of dial wheel member II. The inner end of said spring is fastened to a bar 33 of hub 23 of gear 10, which bar protrudes through a slot 34 in hub 32. The outer end of said spring is fastened to the side of the case as shown in Fig. 3.
As stated above, shaft 2 and gear 3 rotate continuously at a constant speed. When the register is in its inoperative condition, end 25 of clutch control means 6 is pressed down and cylindrically shaped arm 21 thereof is positioned in front of flange 30 and rests lightly against spring 22. As a result, dial wheel assembly 4 remains in its disengaged position with respect to rotating gear 3, as shown in Fig. 3. When end 35 of clutch control means 6 is pressed down, arm 21 thereof moves to a position at the rear of flange 30 as shown in Fig. 1, and is held in such position by flange 30. Arm 21 when in this position exerts pressure on the curved part, particularly on flange. 24 of clutch spring 22. Pressure exerted on this part of spring 22 causes its ends to move toward each other. This movement of the end which is fastened to shifting fork 20 causes the entire dial wheel assembly to slide along hub 9 to a position such that escape ment spring l9 flts in between one of escapement teeth 12 and one of escapement teeth l3 and such that the regular teeth of gear 10 mesh with the regular teeth of gear 3. Since the forward edges of escapement teeth 12 are straight or horizontal, escapement spring 19 prevents the rotation of dial wheel member I l. However, since the forward edges of escapement teeth 13 slope I toward the face of gear I!) and since dial wheel member II is loosely mounted on gear H), escapement spring i9 does not interfere with the rotation of gear l0, and hence, gear ill begins to rotate with gear 3 at a constant predetermined speed. Since one end of escapement tension spring 16 is connected to gear Ill and the other end to dial wheel member II, the rotation of gear [0 distorts spring 14. The rotation of gear 10 causes escapement spring i9 b l f ed.
by the sloping edge of the next succeeding one of teeth l3 gradually out of engagement with the straight or horizontal edge of tooth 12. This disengagement occurs when the straight edge of the next succeeding one of teeth 13 is substantially in alignment withthe straight edge of tooth 12. As soon as this disengagement occurs, tension spring 14 becomes effective to cause dial wheel member II to rotate very rapidly in the same direction as gear 10 and quickly overtake said gear. As dial wheel member ll rotates, escapement spring l9 slides down the sloping edge of tooth 12, so to speak, until it reaches a position such that the straight edge of the next succeeding one of teeth 12 encounters said spring. The engagement of said next succeeding one of teeth 12 with escapement spring 19 again prevents the rotation of dial wheel member H. The further rotation of gear [0 again causes escapement spring l9 to be lifted by the sloping edge of the next succeeding one of out of engagement with the straight edge of tooth l2, and the cycle of operations described above is repeated until dial wheel member H has rotated substantially one revolution. The position of escapement spring [9 and the positions of teeth 12 and I3 are such that only one numbered section on the periphery of the dial wheel member H is visible through window l5 at any one time. The speed at which gear Ill rotates is such that each successive number on the periphery of the dial wheel member remains visible through window IS a predetermined period of time, for example, five minutes. At the end of each period of time the number then visible quickly disappears and almost simultaneously with such disappearance the next higher number appears. When dial wheel member ll rotates substantially one revolution, tripping member 31 comes in contact with and presses down flange 28 of control spring 1. This causes flange 30 of spring 1 to be pressed down to a position below arm 21 of clutch control means 6. Clutch spring 22, being distorted, quickly moves arm 21 to its normal unoperated position in front of flange 30, which, of course, causes arm 25 to move downward and arnr 35 to move upward. Simultaneously with the release of clutch control means 6, the ends of spring 22 spread out. or move apart. This movement of the end to which shifting fork 20 is fastened moves said shifting fork to the right, which in turn slides the entire dial wheel assembly to the right along hub 9. This disengages gear 10 from gear 3 and teeth 12 and I3 from escapement spring 19. Reset coil spring 8, which was wound up by the rotation of gear l0 and dial wheel member ll, now becomes effective to cause the entire dial wheel assembly to rotate in the opposite direction until tripping cam 3| comes in contact with flange 29 and stops the reverse rotation of the dial wheel assembly, at which time the dial wheel assembly is in its normal zero position. The apparatus is now in its inoperative condition. It can be seen from the above descriptionthat at the end of a predetermined number of timing periods the apparatus automatically releases the clutch control means and the clutch means and automatically restores itself to its normal inoperative condition. However, it may be restored to its normal inoperative condition at any time by pressing down end 25 of clutch control means 6. If end 25 of clutch means 6 is pressed down teeth I 3 gradually against flange 30 with sufiicient force to cause bered I suddenly disappears and section numflange 30 to move down and permit arm 21 to bered 2 immediately becomes visible through position in front of said flange.
