Inventor: BURRIDGE LEE SPEAR
Filed: 1907-02-11
Granted: 1907-08-22
Abstract: 3361. Burridge, L. S. Feb. 11. Typewriters.-Relates (1) to automatically - reversing ribbon-feed mechanism, and (2) to variable-t h row ribbon - vibrating mechanism, shown as applied to a Sun machine. (1) The spools on opposite sides of the machine are driven by toothed gearing from a tilting shaft 27, Figs. 1 and 6, actuated by pawl- and - ratchet mechanism 25, 24 from the usual universal bar 12, engaged by the type-bars 1 and controlling the carriagefeeding mechanism. The shaft 27 is carried by a bail 72 pivoted on a screw 73, and extends through slotted links 78 on levers 76 arranged for actuation by shifters 80 pivoted on the arms 43, 45 of a second universal bar 44, engaged by the key-levers. 9 and independent of the carriage-feeding mechanism. Followers 84, 83 riding on the ribbon spools co-operate with the shifters 80 normally to prevent engagement with the levers 76, engagement being allowed when the end of a follower drops into an opening 87 in the spool core. In order to reduce the force required to separate the ribbon gears 28, 29, Fig. 2, the gear 29 is not on the spool 30, but is connected through gears 91, 90. The gear 90 is secured on a hollow hub 92, on which the spool is yieldingly retained by a spring 97. The space key 101, Fig. 1, operates the escapement mechanism through the arm 23 connected with the universal bar 12 and carrying the ribbon-feed pawl 24, which is tripped by the rear end 103 of the space-key lever to prevent ribbon feed. (2) The ribbon - vibrator 33, Fig. 1, is operated from the second universal bar 44, the arm 43 being connected by a link 42 slotted at 59 over a wrist 41 on an arm 40 of a rock-shaft 36 carrying the vibrator in arms 35. For variable throw, the link 42 is provided with a wrist 61, engaging in a slot 60 in the arm 43 and adjustable by means of a finger-piece 63 and lever 64, retained by a spring detent 70. The slot 60 preferably terminates in an enlargement 62 so that the vibration can be completely prevented for mimeograph work &c. In order to obtain a uniform movement of the universal bar 44 by the several keylevers 9, the rear edge of the universal bar is stepped. In order to adjust the vibrator with the platen 5 in the carriage-shift movements, the link 42 is connected by a link 49 to the shift frame 50, and the wrist 41 is cammed forwardly by the slot 59 when the link 42 is lifted by the frame 50. The ribbon guides 32, Fig. 6, are situated directly over the spools and forward of the vibrator and diverging rearwardly and downwardly.

Abstract: 4583. Brookes, A. G., [Foote, T. M., Wolfe, W. F., and Young, A.V.]. Feb. 25. Switches.-The movable contacts of a switch are mounted upon a universal joint, and an undulating motion is given to them whereby they are bridged by a third fixed or movable contact-piece. A ring 3 is supported by two set-screws 2 carried by supports 1, while a disk 5 is carried by two screws 4 on the ring 3 placed at right-angles to the screws 2. Depending from the disk 5 are two projections 6 carrying set-screws 7, which support a ring 8, the ring being provided with set-screws 9 supporting a ring 10. The ring 10 carries supports 11, the upper ends of which are provided with insulating- pieces 12, upon which rest contact-rings 13, 14. Each of these rings consists of one or several parts insulated, from each other, the ring 13 being connected to a source of current, and the ring 14 or its parts to some power-absorbing, machine. A clock-work or other driving-mechanism is arranged under the disks, and is adapted to drive radial arms 25, 26, 27, 28 carrying four wheels such as 29, 31, 32, &c., the wheels 29 31 being of different diameters, while two others of equal diameter are intermediate of the wheels 29 and 31. Above the disk 5, a short column 15 of insulating-material carries a revoluble lever 16. An adjustable lever 18 carrying a contact-shoe 20 is pivoted to the arm 16 at 17, the inclination of the arm'being varied by a screw 21. As the wheel 31 revolves, the highest point of the contact-rings 13, 14 revolves, and when it comes under the arm 18 the shoe 20 bridges the contact-pieces, and the circuit is completed. Two levers such as 18 may be provided so that two circuits may be completed.intermittently, the interval between the completions being varied by varying the position of the arms ; or, the arm 16 may be given a revolving motion, the relative speed of arms 25, &c., and the arm 16 varying the period of contact or the interval between two contacts. By mounting the disk 5 on a universal joint, the action of the switch is not affected by the .oscillations of the body upon which it is placed. If the outer ring 14 is divided into two parts each connected with a motor and a common source of current, the latter being connected to the ring 13, motors will be driven intermittently.

Title: Improvements in the Manufacture of Explosives.
Inventor: CORNARO GIOANNI
Filed: 1907-04-19
Granted: 1907-09-05
Abstract: 9170. Cornaro, G. April 21, 1906, [date applied for under Patents Act, 1901]. Explosives. - One or more very finely divided common metals, such as antimony and aluminium, which, when mixed with potassium nitrate or other highly.oxidized compound, oxidize with violence and the development of much thermal energy, are utilized as explosives. Greater explosive force is obtained if an intimate mixture is employed of two or more metals which begin to oxidize at different temperatures, the successively-formed oxygen compounds developing increasing quantities of heat, thereby facilitating the oxidation of the metal or metals which oxidize at the higher temperature. Whenpotassium nitrate is employed as the oxidizing- agent, the explosion does not take place below 300‹ C., and is not readily produced by impact or friction. The cooling and condensation of the gases which occur on explosion causes the production of a thick, slowly-dispersing smoke, enabling the location of the explosion to be detected at a distance. Metals liable to become oxidized at ordinary temperatures may be coated with an inflammable paste produced by mixing soot, boiled linseed oil, and essence of turpentine.

Title: Improvements in and relating to Steering Gear for Traction Engines.
Inventor: BARTHOLOMEW JOHN BARTON
Filed: 1907-10-21
Granted: 1908-05-07
Abstract: 23,246. Bartholomew, J. B. Oct. 21. Traction engines.-A traction engine is provided with a special form of combined manual and powerdriven steering-gear which may be worked by a single handle or wheel. An I-beam 7 projects from the main frame 1 and overhangs the axle 8 of the steering-wheels, the axle being pivotally secured to the beam. A steering-fork 9 receives the telescoping rod 10 which is mounted in the forward end of a U-shaped frame 11, which is pivoted to the nut 12 on the steering-screw 13 and has a tail-piece 14 slidably mounted in the bracket 15. The nut 12 is moved to turn the steering-axle. The hand steering-wheel 21 is connected by the shaft 20 and gearing 19, 18, 17, 16 with the shaft 13. The spurwheel 22 on the screw 13 is driven by a pinion 23 on the shaft of an engine 24. To control the engine 24, the hand-wheel 21 is secured to a sleeve 27 carrying a nut 28 which engages threads 20<1> on the shaft 20. At its forward end, the nut 28 is grooved to receive a strap 29 connected by links 30 to the forked arm 32, which is mounted at one end of a shaft 33 extending across the main frame and carrying at its opposite end a second crankarm 34. A link 35 connects the arm 34 with the links of the engine 24. By turning the wheel 21. the engineer gives to the nut 28 a combined rotary and longitudinal movement ; the latter movement rocks the shaft 33 so as to swing the arm 34, thus starting the engine and steering the vehicle. As the shaft 20 is connected through gearing with the screw 13, the rotation of this screw by the engine shaft turns the shaft 20 so as to restore the nut 28 to its normal position and stop the engine. To turn the steering-wheels in the opposite direction, the movement of the hand-wheel 21 is reversed, thus shifting the nut 28 so as to reverse the engine 24. To change from power to hand-steering, the upper end of the shaft 20 is squared to slide within a sleeve 41 which fits within the upper end of a sleeve 27 and the hub of the hand-wheel. The outer end of the sleeve 41 carries a clutch-wheel 42 provided on its inner face with a series of notches 42<1> and adapted to be locked to the hand-wheel. When the engine is to be steered by power, the hand-wheel is disconnected from the clutch wheel 42, when it is steered by hand, the toggle-lever clutch is thrown into gear so that sleeve and shaft work together as one piece. The engine 24 is preferably disconnected from the screw 13 when steering by hand, and suitable means such as a locking-pin 45 is mounted in a collar 46, which is keyed to the end of the shaft 13 and serves to retain the gear 22 in position.
