Title: Clutch-brake driving mechanism
IPC: F16D67/02
Filed: 1953-04-23
Abstract: 725,202. Motor driving arrangements. SINGER MANUFACTURING CO. April 23, 1953 [May 1, 1952], No. 11184/53. Class 35. [Also in Groups XXIV and XXXIV] In a drive unit of the type in which either a flywheel 23 (driven by an electric motor) or a brake member 25 is engaged by a clutch disc 19 on a shaft 18, when the latter is slidden axially upon operation of a control lever 28, means are provided whereby the lever is adjustably spring urged to maintain the clutch disc in the neutral or disengaged position and these means can be alternatively so adjusted that the clutch disc is maintained in engagement by spring-force with either the brake member or the flywheel; in the latter cases the force necessary to engage the disc with the flywheel or brake, respectively, can be adjusted to require a light pressure for initial engagement, followed by a substantially greater pressure for complete engagement. The control lever 28 is pivoted on a pin 29 secured to the casing and carries at its end a fork 36, Fig. 2, and pin 33, the latter engaging in a groove 15 in an axially slidable and rotatable sleeve 14 supporting the driven shaft 18 to which the clutch disc 19 is secured. A C- shaped bracket 41 secured to the casing has a slot 43 in its bottom portion along which are slidable two set-screws 44, 48, and a pin 37 on the control lever passes through a hole in a U-shaped return lever 40 lying within the bracket 41. A hairpin spring 52 engages the bracket and a recess 54 in the return lever to urge the latter downwardly on to the screws 44, 48 and, through the pin 37, react on the control lever 28. By sliding the screws 44, 48 along the slot 43, the fulcrum point or points of the return lever 40 are adjusted, and hence the effect of the spring 52 on the lever 28 is controlled. For example, with the screws 44, 48 moved in the slot 43 to the position shown in Fig. 1 where the recess 54 engaged by the end of the sprong 52 lies between them, the lever 28 is biased to the neutral position, and vertical adjustment of the screws, by turning them, controls the distance separating the clutch disc 19 from the flywheel and brake and the space between the two screws controls the effective pressure of the spring 52. When the screws have been slidden along the slot 43 to the position shown in Fig. 4, with the recess 54 to the right of both of them, the control lever 28 is biased to the brake engaging position; initial depression of the control lever to disengage the brake and engage the clutch requires a light force to overcome the pressure of the spring 52 as the return lever pivots about the screw 44, complete engagement requiring greater force as the lever now pivots about the screw 48 with increased lever length between its fulcrum and the recess 54. Similarly the screws can be slidden along the slot 43 to the right so that the clutch disc 19 is engaged with the flywheel 23 by the pressure of the spring 52, which pressure has to be overcome by the operation of the lever 28 to disengage the clutch.
