Title: Improvements in or relating to clutches
IPC: F16D11/02
Filed: 1945-04-11
Abstract: 590,044. Positive clutches. BRITISH UNITED SHOE MACHINERY CO., Ltd., and KEALL, F. B. April 11, 1945, No. 8936. [Class 80 (ii)] Engagement of a radially sliding key 14 of a one-revolution clutch in a power press, e.g., for cutting out sheet-leather in boot manufacture, is cushioned by connecting the key-engaging driving-dog 22 with its supporting and driving flywheel 20 through a toggle, either limb 28 or 34 of which is in the form of an extensible spring, e.g., 28 which acts to thrust the driving-dog in the direction of drive. Friction augments the spring resistance, and after a limited yield, drive becomes positive through contacting stops and the spring is relieved of stress. The driving-dog 22 is circumferentially slidable in a housing 24, secured to the driving flywheel 20 and is pressed by the spring 28 against a stop 26 in the housing, the spring-reaction being taken by the rigid toggle-limb 34, pivoted at 36 on the flywheel 20 and, in the starting position shown, bearing against a stationary pin 40. In operation, when control means, not described, permits the key 14 on the driven-shaft 10 to move outwards, it is engaged by the driving-dog 22 and drive passes from the flywheel 20 through the rigid limb 34, spring 28, dog 22 and key 14 to the driven-shaft 10. The spring 28 yields and the dog 22 slides circumferentially on faces 54, 56, which provide frictional resistance, until faces 50, 52 on the dog 22 and housing 24 abut, whereupon the drive becomes rigid. On further rotation, the rigid limb 34 rides off a stationary cam surface 42, adjacent the pin 40, whereupon stress in the spring 28 is relieved by opening of the toggle 28, 34, against a light return spring 38. At the end of a revolution the key 14 is retracted by means not described, and the toggle-limb 34 resets in the starting position shown, by a cam extension 35 of the limb which rides up the fixed pin 40. In a modification, Figs. 2, 3 and 4 (not shown), the driving-dog 22 has a pin-and-slot connection with the flywheel 20, the step 50 being omitted, and the rigid and spring limbs 34, 28 of the toggle are interchanged. The stationary stop 40 and cam surface 42 are also omitted, the knuckle of the toggle being moved inwardly to straighten the toggle as the spring yields, by means of a member sliding on a curved face on the flywheel, the member being pivoted on an extension of the rigid limb and arranged to abut a surface on the spring limb after a predetermined yield of the toggle is prevented. The drive is thus picked up gradually by the spring. An additional spring may be arranged circumferentially between the driving dog 22 and the adjacent rigid limb. Specification 22,023/05, [Class 31], is referred to.

[Classes 13 and 118 (ii).] Sound locating apparatus consists of one or more pairs of horns A, B connected to ear-pieces 14a and secured to a frame 9 which is trunnioned in standards 6 on a rotatable carriage 7. The centres of the mouths of the horns in each pair are separated by a distance not greater than the longest wave - length to be received, and each horn has a crosssectional area varying exponentially according to the equation A = A0e<mx>, where A is the area at a distance x from the small end A0, and m is 4#/L, L being the longest wavelength to be received. As an example, for a total length of horn of 126 ins., the rectangular mouth section 11 is 48 ins. long, and the reverse curve section 12, support section 5, and flexible section 13 are each 26 ins. The diameter of the large end is 30 ins., and that of the small end from # to 1 inch. For a frequency of 30 cycles per second, the constant m is 0À03 for inch units, and the area A increases by 6 per cent for every two inches of length, giving an angle of 30‹ between opposite walls of the mouth. The elbow 15 has a radius not less than the dimension of the horn section in the plane of the bend, and the section 12 is formed with a web 16 to which the mouth section is attached. The wall 17 of the mouth section is flat and the other three walls are flared, the wall 18 having a more pronounced curvature to baffle non-frontal waves, as shown in Fig. 4 ; this effect is aided by slightly converging the walls 17 of opposite horns.
