Title: Improvements relating to actuating mechanism for variable speed gears
IPC: F16H63/30
Filed: 1933-02-24
Abstract: 410,580. Controlling variable-speed gearing. ARCHDALE & CO., Ltd., J., and JEWSBURY, J., Ledsam Street, Birmingham. Feb. 24, 1933, No. 5672. [Class 80 (ii).] Variable-speed gearing is controlled from a shaft or member d which is turned to different final positions by the sliding of a preselected member b. The slider b is first turned from a preselector h so as to slide in different guides or be otherwise held while sliding in different fixed angular positions so that the final position of the transmitting member d is varied. In a form shown in Fig. 1, the member d is a sleeve which turns upon the slider b which passes through it. Upon a crank k the slider b carries inner and outer bowls b, m, Fig. 2. The preselector h turns the slider b so as to bring the outer bowl m opposite one of a number of guide slots p in a fixed cylinder o. Then a lever c, Fig. 1, which may be connected to the main clutch pedal on a vehicle, slides the slider b so as to bring the inner bowl l against a profile cam n on the member d, the member d is turned until the bowl reaches the bottom q of the V-cam n. There is a return spring r. A cam g is shown by which the member d operates a gear-changing striker fork e, but the gearchanging means beyond the member d may be of any suitable form such as a simple lever. In a form shown in Fig. 4, the cylinder o and outer bowl m are dispensed with. The slider b is in the form of a cup carrying the inner bowl l and having a sliding-pin u and gear connection t with the preselector h. The preselection turns one of a number of notches v on the slider b opposite a dog x operated by the lever c which dog holds the slider b against turning as the bowl l strikes the profile cam n and turns the transmitting member d to its final characteristic position. In a form shown in Fig. 5, the profile cam n is on the slider b which is kept from turning after preselection by engaging guide slots 2 on a fixed shaft y which passes through and supports the member d which carries the bowl l which co-operates with the cam n.

Abstract: 563,334. Fish dressing machines. FISADCO, Ltd., and LAWRIE, F. April 19, 1943, No. 6266. [Class 28 (ii)] In a fish dressing machine the tails of the fish are gripped between one or more smooth-faced hammer-like members 11, 12, and a serrated plate 13. A series of such grippers are mounted on a rotary table 7, receiving the fish from pocket 1 of an adjacent rotary feed table. The fish are then operated on in turn by a slitting disc knife 8, a gill remover 9 and a disc cleaning-brush 10. The hammers have narrow faces and the serrations are formed by parallel grooves at an angle different to that of the hammers. The serrations are undercut as shown in Fig. 4 to assist the grip on the tail. The serrated plate may consist of a brass serrated face 30 and a steel bar 31 with an intermediate resilient layer of rubber. The hammer 11 is part of a bell-crank lever continuously urged down by the pull of a spring, but is controlled in its rise and fall through a pin-and-slot connection 26, 27 to the hammer 12 which is raised by a fixed cam 15 against the pull of a spring 20.

Abstract: 176,387. Wagner, K. W., and K³pfm³ller, K. March 7, 1921, [Convention date]. Void [Published under Sect. 91 of the Act]. Thermionic relays. -To increase the speed of telegraphing over long lines such as submarine cables, the effect upon the receiving apparatus is made to depend upon a current-time curve which is the sum of the curve for the rise of current under constant electromotive force applied to a simple line' 'and a curve derived therefrom by differentiation, together with one or more curves derived by second and higher differentiations. The lower curve, Fig. 5, represents the rise of current under constant electromotive force in a simple line, current strength #0 being plotted against time. In known apparatus the effect in the receiver is made to depend upon this curve compounded with a curve derived therefrom by differentiation. The present invention seeks to approximate more closely to the desirable rectangular form of curve by including also components due to second and higher differentiation, the current In being of the general form In = a (#0 + #1 #1 + #2 #2 + ... + #<n> #<n>) where a, #1, #2 .. #<n> are constants depending upon the electrical constants of the circuits used in a manner described in the Specification, and #1 = d#0 / dt, #2 = d<2> #0 / dt<2> , ... #<n> = d<n> #0 / dt<n> The upper curve, Fig. 5, represents the approximation obtained by the use of four terms in which the numerical values of #1, #2, #3, #4 are respectively 1.4 x 10-<1>, 4.5 x 10<-3>, 4.5 x 10-<5>, and 1.4 x 10-<7>. Fig. 6 shows a suitable circuit arrangement in which resistances Q1' Q2' Qn in series are bridged by condensers K1, K2, Kn, and resistances r1, r2, rn, rn + 1 are in parallel.

Filed: 1923-03-07
Abstract: 207,448. Rogers, F. H. March 7, 1923. Regulating.-In hydraulic turbines and pumps, the gates or guide vanes 7 are actuated by a rotatably mounted ring 12 and links 11 connected to levers 10 on the valve spindles, the arrangement being such that a steady movement and pressure of the ring 12 transmits a decreasing movement and an increasing force to the gates in the closing direction. The ring 12 is actuated by a piston rod 14, and may be located outside the ring of gates. The links 11 are formed as safety members which yield under excessive stress or strain arising, for example, from an obstruction in the gates. Fig. 3 shows such a link comprising two parts 25, 26 held against relative sliding by a split ring 27 adapted to be sheared under excessive compression or tension. Other forms of safety links may be used, including breakable pins and the like, and devices for preventing fouling of the released parts.
