Granted: 1899-06-24
Abstract: 9257. Clark, A. M., [Wagner Typewriter Co.]. May 2. Type-writers.-Relates to paper carriage and index mechanism for type-writers. The paper carriage, which is adapted to reciprocate in the main frame, is provided with an auxiliary frame 3 which forms the platen frame and carries the platen 4. The frame 3 is provided with suitable mechanism for moving it in a vertical direction. Feed-rollers 8, which pass through apertures in the paper shield 5, are loosely mounted upon a shaft. 9 carried by arms 10. The arms 10 have sleeves 12 with ratchet faces which engage corresponding ratchet teeth on sleeves 14 loosely carried on a rod 15. Each of the sleeves 14 is connected by a coiled spring 17 to a fixed sleeve 18 on the shaft 15, so that, by the rotation of the sleeves 14, the tension of the springs upon the arms 10 may be adjusted. Cams on the ends of the shaft 9 engage arms 20 near each end of the platen, which arms are fixed upon a longitudinally-sliding rod 21. The arms are provided with extensions 22 having cam fingers 23 which co-operate with an abutment 24 connected with the support 25 of the marginal rollers 26 adapted to bear upon the paper near each end of the platen. The supports 25 consist of spring arms secured at 28 to the frame 3. By moving the rod 21, the rollers 8 and 26 are moved into or out of contact with the paper on the platen. A hand lever 29 is provided for the operation of this rod. An independent feed-roller 33 is pivoted in a spring frame 34 secured to an extension of the rod 15, and is kept in contact with the platen by the spring of the frame. The frame 34 is provided with a pin 37 which engages a cam 38 carried by the rod 21 so arranged that the operation of the rod causes the roller 33 to be moved out of contact with the platen. The rod 21 is also provided with studs 39 carrying pins 40 which engage slots in a movable indicator bar or scale 42 connected to the platen frame by a link 43. The indices upon the scale are so arranged that an index will always be brought to the printing point when the scale is elevated by the lever 29. The scale also indicates the line on which the characters will be written. When the scale is moved to the position shown in dotted lines, Fig. 2, it does not interfere with the writing. In Fig. 4 a type-bar 46 is shown in the printing position with a ribbon 47 interposed between the characters on the type-bar and the paper on the platen.

Patent GB-190013139-A (GB)
Title: Improvements connected with the Lighting and Extinguishing of Street and other Gas Lamps at Predetermined Times.
Inventor: HOOK HARRY
Filed: 1900-07-20
Granted: 1901-01-19
Abstract: 13,139. Hook, H. July 20. Lighting and extinguishing gas.-The cock controlling the supply of gas to the main or pilot burner of street or other lamps is actuated at predetermined times by clockwork mechanism. This mechanism c rotates, once in twenty-four hours, a wheel d, to which the hands e, e' are fixed in positions corresponding to the predetermined times. As the wheel d revolves, the hand e fixed to it strikes against the crank f, and lifts the lever g, which, by means of a pin g<1>, raises a lever h. The engagement of this lever with a catch i normally prevents the wheel from being rotated by the spring l. The lifting of the lever h causes a second lever h' on the spindle h<2> to rise into contact with an arm carried by a lever j<1> mounted on the same spindle J<2> as a second lever n. When the lever g has raised the lever h clear of the catch i<1>, the rotation of the wheel i is prevented by the engagement of a stud i<2> on it with the curved portion of the lever g, as indicated by dotted lines in Fig. 2, and the lever h<1> passes beyond the arm j, allowing the roller j<3> thereon to fall back into the depression m on the cam k. The hand e has then passed clear of the crank f, and the lever g has fallen back to its original position, releasing the wheel i, which then revolves, the lever h being held clear of the catch i by the lever h<1> resting on the arm j. The revolution of the wheel i is communicated by gearing to the cam k, which lifts the roller j<3> from the depression m, thereby releasing the lever h from the arm j and allowing the lever h to fall. The fall of the lever h to its original position in engagement with the catch i<1> is, however, prevented by a pin n' on the lever n until the roller j<3> falls into the second depression m<1> on the cam k, when the lever h engages with the catch i<1> and stops the movement. By means of a rod o connected to the cam k at k<2>, the movement of the cam is transmitted through the pivoted lever p and the chains r to the lever s of the gas cock. Similarly the lever s of the gas cock is again actuated when the hand e<1> strikes the crank f.
Patent GB-190102526-A (GB)
Title: Improvements in Cork Extractors
Inventor: HADDAN HERBERT JOHN
Filed: 1901-02-05
Granted: 1901-04-06
Abstract: 2526. Haddan, H. J., [Callahan, J.]. Feb. 5. Corkscrews and cork-drawers.-The corkscrew 20 is revolubly mounted in the sliding block 16, which is connected by the link 14 to the arm 13 of the pivoted operating-lever 12. The block 16, and the nut 22 through which the corkscrew works, are prevented from rotating by their projecting wings 17, 23 engaging the guiding-ribs 18. The nut is recessed at 26, Fig. 4, to receive the projection 29 of the rod 27, which has also a pin 32 adapted to engage in the aperture 33 of the casing, and two arms 35, 34, the latter of which is normally engaged between the projections 36 on the casing 10. During the operation of extracting the cork, the bottle is held between the two pivoted jaws 47, which are lined with rubber &c. 49, and are closed round the neck by the rollers 41 on the operating- lever 37 engaging the cams 50 on the jaws. The jaws are provided with hooks 51 engaging the guide-plate 52, and, when closed, are locked by the lever 42 so as to leave both hands of the operator free. The lever 42 is pivoted on the lever 37, and has a cam surface, which forces the gripping-plate 44 into engagement with the wedging-surface 43 on the casing. In operation, when the bottle neck has been inserted and locked between the jaws 47, the lever 12 is pulled forward and downward, thereby causing the block 16 to descend, and the screw 20 to enter the cork. When the link 14 has passed the " dead point," the further movement of the lever causes the link 14 to engage the arm 35 of the rod 27, and to turn the rod so as to release the arm 34 from the projections 36. The same movement of the rod disengages the pin 32 from the aperture 33, and engages it in the recess 21, Fig. 4, in the block 16, so locking the block 16, rod 27, and nut 22 together. A further movement of the lever 12 raises the block, rod, and nut, and extracts the cork from the bottle. The return movement of the lever 12 re-sets the parts, and strips the cork from the screw. If the bottle is allowed to remain in the gripping-jaws, the cork can be re-inserted in the bottle by the return movement of the lever.
