Title: Improvements in or relating to cam drive mechanisms
Inventor: BALLANTYNE JAMES GRAHAM
IPC: F16H25/02
Filed: 1959-10-12
Abstract: 932,273. Cam mechanisms. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Oct. 19, 1960 [Oct. 12, 1959], No. 34490/59. Class 80 (3). [Also in Group XXIX] A member 18 is moved linearly in a direction B by the reciprocation, transverse to this direction, of two or more out-of-phase members 15, 16, engaging a waveform cam surface, such as a slot 17, on the member 18. Guides (not shown) assist the members 15, 16 over each apex of the cam. As shown the members 15, 16 are reciprocated by pistons 21, 22 which also control (through means not shown) respective reversing valves 26, 27 and stop valves 34, 35. A valve 23 controlling the direction A of fluid flow is set to determine the direction B of motion of member 18. In the position shown valves 34, 35 are closed and fluid flows from valve 23 to the top of cylinder 19, fluid expelled from the bottom of this cylinder being fed to the top of cylinder 20. Hence both pistons 21, 22 are depressed, fluid from the bottom of cylinder 20 being returned to valve 23. As the member 15 nears the cam apex 37, valve 34 is gradually opened to short-circuit cylinder 19 so that piston 21 idles and the member 15 is moved over the apex by the continuing movement of member 18. Thereupon the valve 26 is automatically switched to supply fluid to the bottom of cylinder 19 and the valve 34 is again closed so that member 15 is now moved up the cam part 17a while member 16 continues its downward movement. Similarly as member 16 reaches the apex 37 the valves 35, 27 are automatically operated to enable it to idle over the apex. In a modification the cam slot is replaced by a singlesided cam of waveform engaged by three reciprocating members one of which acts in opposition to the others to take up backlash. Alternatively two such cams running along the length of the output member may each be engaged by three reciprocating members, said six members being arranged in three opposed or three staggered pairs.

In a machine according to claim 1 of Specification 931,796 the flange forming means operates inwardly to form an inwardly projecting marginal flange on the upper. The outer mould 234 comprises a resilient pad. The upper assembled on the heated heelward part 226 of the inner form is gripped and stretched toewardly by operation of treadle rod 214 which first closes joint 206 and then rocks bracket 210, the latter being adjustable heightwise by means of handwheel 212, and is clamped to the forepart 325 of the inner form by side clamps 218 operated via toggle 222 by means of handle 224. The outer form 234 is yieldably mounted, by means of an adjustable spring, on a carriage 236, and is moved to engage the back-seam of the shoe by means of a handle 24 operating via toggle 239. The flange former 242 is fixed to carriage 236, and when the outer form yields on engagement with the shoe the flange former continues to move with the carriage and wipes the margin of the upper inwardly. A pneumatic device 232 is then actuated by means of valve 233 and acts via pivoted lever 230 to force the inner form part 226 still harder into the outer form 234. The latter yields a little more and causes a slight additional wipe to take place. The single wiper 242 is heated electrically, and may be replaced by a pair of conventional type heated hinged wipers.

Filed: 1935-12-14
Abstract: 467,214. Type-bar-making machines. SHALOM, S.-E. ISH-, and BLOOM, O. I. Dec. 14, 1935, No. 34763. [Class 100 (iii)] Keys and keyboards; matrices.-Relates to the method of composing in languages, such as Hebrew, that comprise a large number of characters, according to which a number of the characters are built up from elements, which are meaningless in themselves and are carried on separate matrices, as shown in Fig. 8. (1) In order to facilitate composition, each key bears a representation, not only of the element or part-character on the corresponding matrix, but also of the complementary part or parts of a character. The operator thus has a complete character before him instead of a meaningless element, and is thereby aided in the selection of the succeeding elements necessary to complete the desired character. The parts of each character are displayed in a contrasting manner ; they may be partly in black and partly in outline, as shown in Fig. 3, or may be in contrasting colours. (2) A set of fifty-six element-bearing matrices is provided, from which all of the characters of the fount known as " classical " Hebrew, which are more rounded in form than the " modern " or square-shaped characters, can be built up. The remainder of the ninety keys of an ordinary keyboard may be used for complete characters and punctuation marks. As the fount is not divided into upper and lower case characters, each matrix may bear a character in outline in addition to the usual solid character, as shown in Fig. 4.

Another bellowsshaped element 21 is fluid tight connected to the portion 14 and the plate 16 and is connected to a pump 23. If an increased static load is applied to the vehicle, and the sprung member A sinks below a predetermined level, the pump 23 can be made to force selected volumes of fluid into the chamber 24 and therefore to lower the plate' 16. This causes the pressure, in the chamber 20 (and also therefore in the chambers 12); to increase and reset the sprung member A to its normal level. In a modification, Fig. 2 (part only, shown), the hydraulic control chamber is formed by a casing 25, the mouth of which is sealed by a flexible wall 26 connected at 28 to the plate 16. The chamber 24 could be connected to an engine lubricating circuit with the addition of an adjustable pressure-reducing valve.
