Title: Improvements in Platen Printing Presses.
Filed: 1902-10-21
Granted: 1904-01-21
Abstract: 22,869. Waite, F., and Waite & Saville. Oct. 21. Platen presses; inking-apparatus.-Relates to improvements in platen presses, especially those of the type described in Specification No. 12,878, A.D. 1898. The inking-cylinder 8 is mounted on the rocking-arms 3 which carry the type-bed, and is driven by a sprocket-chain 12 which derives its motion, through gearing, from the wheel 7. The chain is diverted by guide-wheels 20 to clear the framework of the machine The inking-rollers 23 are carried by the ends 24 of spindles 25 mounted in swing brackets 26. Spiral springs 27, on the spindles, keep the rollers pressed against the cylinder or the type. A stud 43 on an arm 30 on one of the brackets 26 works in a slot in the bridle link 32, which is pivoted at the other end to a stud 33. As the type-bed moves away from the platen, the bridle link causes the inking-rollers to pass from the inking-cylinder down over the type on to the lower bearers 34, the reverse movement taking place as the bed returns. The stud 43 on the bracket 26 also moves in a curved slot 41 in arm 40 on the link 32. The slot is so shaped that the inking-rollers remain for a period in contact with the cylinder. To obtain a uniform application of ink, one or more of the rollers are made with wider end bowls than the rest, and are held clear of the type-bed by lifter bars 50 during the forward stroke of the rollers. On the return stroke, the lifter bars are moved out of the way, and the rollers ink the forme in the ordinary manner. The lifter bars have inclined slots 51 which engage with blocks 52 on the side of the type-bed, the bars being actuated by links 55 connected to arms 56 on a rocking-shaft 57. To straighten the sheets evenly against the platen, a light roller or rod 78, Fig. 7, is loosely mounted in slots 79 in the ends of arms 80 on a rocking-shaft 81. The shaft is rocked by a lever-piece 87 actuated by a cam 91. As the platen moves down to the type, the rod 78 moves against and over the sheet carried by the platen, and straightens it, finally passing off the sheet and allowing frisket fingers to come down on the sheet. The Provisional Specification also states that the inking-rollers may be run past the cylinder on to a distributing-plate.

Abstract: 23,865. Lloyd, W. J., and Priest, W. Nov. 3. Motor road vehicles.-Relates to tricycles and like vehicles provided with two independent motors, one running continuously, the other supplementing the power of the first when required ; also to means for supporting a fore-carriage on spiral springs. The supplementary motor is started or stopped by a lever putting a friction clutch into or out of gear, and simultaneously closing or opening its electric sparking-circuit. The two motors A, B are shown in plan in Fig. 3. The motor A runs continuously and drives the rear driving-wheel by a belt passing over a belt ring on one side of the wheel. Another belt passes over a belt ring on the other side of the wheel, and over a pulley c, mounted loosely on the crank shaft of the motor B, and connected to the outer part c' of a conical friction clutch. The inner part c<1> of this clutch rotates with the crank shaft, and is pressed into engagement with the outer part c<3> by a spring d when the short arm of the lever h is suitably moved. The arrangement by means of which the foot-lever l operates the lever h is shown in Fig. 4. The end of the long arm of the lever h moves in a slot i in a fixed bracket, the slot being formed with a notch i<2>. The foot-lever l has two lower arms l<1>, l<2>; the arm l<2> moves the end of the long arm of the lever h towards the right, against the resistance of the spring d connected with the friction clutch, until it springs into the notch i<2> ; the cam-shaped arm l<1> forces the long arm of the lever h downwards and out of engagement with the notch i<2>, so that it is free to move to the left under the action of the spring d. The position of the switch f, g for closing or opening the sparking-circuit of the supplementary motor B is shown in Fig. 3. Fig. 9 shows the method of supporting the forecarriage by spiral springs on a framing consisting of two parallel tubes m, secured by clips r to the ends of longitudinal frame tubes p, each tube m having one of the ends of a U-tube n secured to it, the bend of the U-tube being connected by a bracket x to the head tube. Rollers t, placed one on each side of the fore-carriage body, move in slots in plates s fixed to the framing.

Granted: 1905-11-30
Abstract: 7776. Ambler, F. April 12. Seats.-A dry seat for use in parks &c. comprises an endless band of wooden slats arranged to rotate on rollers mounted on the ordinary seat frame. The slats a, a', Fig. 4, are connected to a band b of fabric, leather, or hinged metal pieces or chains, and are shaped so as to gear with teeth formed on the roller d, which is mounted on a shaft f fixed at one end and spirally shaped within the roller so as to offer a torsional resistance to the movement of the slats ; or a separate spring or falling weight may be fitted to the shaft. The other roller c rotates freely on its bearings. A dry seat is obtained by moving the slats until the lower ones a<1> are brought to the top, and so that a catch k pivoted to one of the slats engages with a catch m, pivoted to a cross-bar n, bringing it into the position shown in Figs. 5 and 7. When a person sits down upon the slats, the end p<1> of a lever p is depressed, while the end p<2> disengages the catch k from the piece m, which then falls into the position shown in Fig. 4 and leaves the slats free to return when the sitter rises. The slats are prevented from returning too far by the engagement of a stop q<1>, Fig. 9, projecting from a plate q which slides in the framing A, with another stop s formed on. the roller d, the plate q being mounted on a screwthread d' formed on the axle of the roller. In a modification, the stops q, s are replaced by hooks w, Fig. 4, connected to one of the slats and adapted to engage with a projection v<1> on the framework. Water which drains from the upper slats a falls on to a shield x, and is conveyed away to the side of the seat. According to the Provisional Specification, the slats may be retained in the position for use by the engagement of catch-pieces with a " catch wheel " or the like.

Title: Improvements in connection with Meters for Measuring the Flow of Fluids.
Inventor: FERRIS WALTER
Filed: 1905-05-25
Granted: 1905-11-09
Abstract: 10,980. Ferris, W. May 25. Current meters.- I n liquid meters constructed on the Venturi principle, a secondary passage is arranged in connection with t h e main conduit through which fluid is passing, and is provided with a restricted throat, so that the velocity of the fluid at the throat will be greater that the velocity of flow in the main conduit. Several conformations and arrangements of the main conduit and secondary passage are described and shown in the Specification, Figs. 1, 4, 5, and 10 showing typical examples. Fig. 1 represents the application of the secondary passage to a main of uniform diameter. The increase of velocity at the throat shown results in a diminution of pressure at that point, and the difference between that pressure and the pressure in the main, as indicated by the gauge x<2>, is the measure of the velocity of the flow in the main. The application to a Venturi main is shown in Fig. 4. Gauges x<2>, x<1> indicate the differences of pressure at various points. The decrease of pressure at the throat of the Venturi main is measured by one of the gauges x<2>, and is considerably smaller than that indicated by the other gauge x'. The difference of pressure at each end of the secondary passage is considerable, and the reading of the gauge x<2> is correspondingly great. By this means, small velocities of'the flow in the main can be determined. As shown in Fig. 5, the secondary tube is arranged as a shunt to the main tube; Fig. 10 shows the application to a Venturi main of an arrangement similar to that shown in Fig. 5. Instead of gauges, helical blades rotating in the throat of the secondary tube and driving an external counter may be used.
