Granted: 1906-01-10
Abstract: 503. Techel, H., and Salaschek, M.. Jan. 10. Gas and like engines, reversing in. The valves, igniters, &c. of a multi-cyclinder engine are worked from a shaft which always runs in the same direction. When the engine is to be reversed, the position of the cams relatively to each other on the cam shaft is changed, the shaft as a whole is turned through an angle which is dependent upon the angle the crank shaft has moved through from a given point at the time of reversing, and the direction of running of the crank and cam shaft is changed by reversing-gear. Fig. 4 shows the invention applied to the admission valves of a three-cylinder, four-stroke cycle engine. The cam shaft is disengaged from the driving-wheel A, say, its parts D', D<2>, D<3> are then disengaged from each other, and the cams are adjusted by spur gearing 2, 3, which is brought into action for the purpose, and the cams are re-engaged. The cam shaft is then adjusted as a whole by a hand wheel H and is engaged with the other driving-wheel B. The application of screw gearing, epicyclic gearing, and helical sleeves for moving the cams relatively to each other is also described.

Abstract: 1468. Hill, H. H. Jan. 25. Filing papers &c.-Relates to loose-leaf books, ledgers, &c.in which the papers &c. are filed upon loops carried by slides. The member 2 having the leaf-holding hooks 11 is secured with sliding contact to the fixed member 1 by reason of T-shaped studs 3, 4, engaging with grooves 6, 7 formed on the fixed member, the latter having co-operating hooks 10 secured upon it. The device is locked in its closed position by the T-shaped stud 5 engaging beneath the lug 8, which is raised up from the member 1 so as to be parallel with its surface, and the motion of the sliding piece 2 is also limited by the stop 9. The ends of the hooks 10, 11 are cut diagonally to prevent the papers filed from accidentally slipping off the hooks when in their closed position. The device is secured to the book cover by cementing to it a strip 17 of linen placed between the member 1 and a trough 16 secured to the member 1 by rivets 15. The hooks 10, 11 are made from sheet metal, each hook 11 being formed with a V-shaped notch into which fits the rounded end of its co-operating hook 10. Fig. 9 shows another form of binder, in which the upper member 2<a> is connected to the lower member by lugs 4<a>, cut from the part 2<a>, passing through slots 6<a> in the lower member, beneath which they are bent laterally to provide heads for engaging the underside of the fixed member. The lower member, the hooks 10, and the side members 1<b> are cut from a single sheet of metal, and the upper member 2<a> is also formed similarly. The side members 1<b> are clinched over a sheet of metal, which is of the same size as the member 2<a> and is cut with slots to allow of the movement of the lugs 4<a>, and also over a strip of linen which is cemented to the book cover. The sheets to be filed in the binders are perforated with longitudinal slots parallel to the edges of the sheets, in order to hold the sheets more securely than would be the case with circular perforations.
