Filed: 1927-09-15
Abstract: 302,625. Royce, F. H. Sept. 15, 1927. Shafts; securing together machine elements for transmitting rotary motion.-In resilient driving- means, shown applied to the drive of a timing- gear bevel wheel i from the crank shaft b of an engine, a rigid shaft c<2> and a torsionally flexible shaft c<1> are rigidly coupled torsionally at one end to the shaft b while at the other the shaft c<1> is coupled to the wheel i and the shaft c<2> is connected to the shaft c<1> by a friction coupling allowing only a limited amount of lost motion. The friction coupling serves to damp torsional oscillation of the shaft c<1>. The end of the shaft b is carried in a bearing a and has internal serrations b<1> engaged by similar serrations on the shaft c<1> and on a sleeve c<6> secured to the shaft c<2>. At the other end serrations c<9> on the shaft c' engage with the sleeve of a friction disc c<10>, pressing, under the stress of star shaped springs f, f<1>, upon a flange c<12> on the shaft c<2>, which bears against a flange d<2> on the sleeve d secured to the wheel i<1> friction discs g, g<1> being interposed. The flange d<2> is secured to a drum e carrying a flange e<1> against which bears the spring f, the drum being notched to engage notches of similar size on the disc c<10> and of smaller size on the flange c<12>, thus providing for lost motion between the shaft c<2> and the parts c, d. The notches on the flange c<12> normally lie centrally in the notches in the drum e when the engine is at rest. For starting the engine, a worm-wheel y connected by a friction coupling to the sleeve d is rotated. According to the Provisional Specification, the spring f<1> may be reversed, so that its arms bear on the disc c<10>.

Title: Improved Method and Apparatus for Creped Sheet Production.
IPC: B31F1/16
Filed: 1967-05-26
Abstract: 1,194,252. Corrugating. CARTIERE AM. BROGIO BINDA S.p.A. 26 May, 1967 [26 May, 1966], No. 24759/67. Heading B3Q. [Also in Divisions D1-D2 and E1] Metal foils (e.g. of aluminium) are creped and rendered extensible in all directions by engaging the sheet between opposing areas of two flexible elastic members, each defining a single fluid chamber, distended under fluid pressure within the chambers, and reducing the distension of both areas simultaneously to contract the sheet in all directions. As shown, two rubber sheets 3 and 3<SP>1</SP> are clamped at their edges and inflated by compressed air. A sheet 22 is laid on the lower rubber sheet, and the plate 5, to which the sheet 3 is clamped is lowered, by sliding it along the uprights 6, 6<SP>1</SP>, until the two rubber sheets are in contact over an area greater than that of the sheet 22 (Fig. 2, not shown). The air is then slowly released from inside the rubber sheets, while continuing to lower the plate 5 so that the rubber sheets contract, and contract the sheet 22 also. It may then be pressed between two smooth surfaces. In a continuous process (Fig. 4, not shown), two hollow rollers are supported on parallel shafts and communicate with a supply of compressed air. Each is surrounded by a resilient sleeve, which can be distended by the coinpressed air, through ducts in the hollow rollers, but the distension is restrained on the offrunning side by felt strips running over idler rollers. A strip is fed through the apparatus, is first engaged by the sleeves near the point of their maximum distension and contracts as they contract towards the nip of the rollers. Increased creping can be obtained by repeating the process, and Fig. 5 (not shown) shows three of the continuous apparatus arranged in series for this purpose.
