Granted: 1901-10-19
Abstract: 20,491. Stott, M. Nov. 14. Lathes; end-facing.-A machine for removing the burr from bolt-heads has a hollow spindle a with fast and loose pulleys d, e, and a central rod i to receive the bolt n'. The rod has a squared end k passing through a bracket j to prevent the rod from rotating. The rod is normally projected from the opposite (left) end of the spindle by a spring m to allow the bolt to be inserted, and is moved inwards by a treadle-lever o causing the rim of the head to be trimmed by a cutter g. Any metal forced inwards by the cutter g is removed by a cutter h, which faces the underside of the head. The cutters are mounted in a head f on the rotating spindle. An adjustable stop l on the rod k limits its movement when operated by the treadle, to bring the underside of the bolt-head in line with the cutter h. When the treadle is released, the lever o is withdrawn by a spring, allowing the rod and trimmed bolt to be projected by the spring m.

Title: Improvements in Printing Presses.
Inventor: GRANDY HENRY ATWOOD
Filed: 1901-10-11
Granted: 1902-01-09
Abstract: 20,366. Grandy, H. A. Oct. 11. Cylinder machines with plane printing-surfaces ; rotary machines.-Relates to gripper mechanism for cylinder machines, particularly the colour-printing machine described in Specification No. 18,643, A.D. 1892, [Abridgment Class Printing other than letterpress &c.]. In the gap 15 of the cylinder 10 is a shaft 16 on which the gripping-fingers 17 are adjustably fixed, and by which they are rocked to grip the sheet on the edge 14 of the gap. The shaft 16 is rocked by a pinion 20 engaging . a segment 21 on a lever having a roller 26 engaging a cam 27. The part of the lever carrying the roller 26 is adjustable. The cam 27 does not rotate, but is movable to bring a depre-sion 29 into and out of the path of the roller. This depression 29 permits the grippers to open, but is normally out of operative position, and the cylinder 10 retains the sheet for a desired number of revolutions. The cam 27 is moved, to cause the opening of the grippers at the desired intervals, by a lever 28 engaging a cam 291 on a shaft 30 driven by gears 31, 32. In applying the mechanism to the colourprinting machine described in the above-mentioned Specification, the grippers are actuated so that the cylinder retains the sheet through one or several revolutions. Fingers 33 are provided for lifting the edge of the sheets from the surface 14 after the grippers 17 have opened. The fingers 33 are fixed on a shaft 34 fixed in collars 35 loose on the gripper shaft 16. An arm 37 fixed on the shaft 34 is pulled by a spring 38 to hold the fingers 33 down on the surface 14. An extension 39 of the arm 37 bears a curved adjustable hook 40 concentric with the shaft 16. On the shaft 16 is a latch 42, which engages the hook 40 and lifts the fingers 33, after the grippers 17 have been opened. A cam 44 draws the latch 42 inwards, and it releases the hook 40, permitting the lifting-fingers 33 to drop before the grippers 17 are closed.

Title: Improvements in Machinery for Crushing or Grinding Ore, Rock Cement, and the like.
Inventor: HONEYWOOD DAVID
Filed: 1901-10-31
Granted: 1902-11-29
Abstract: 21,952. Honeywood, D. Oct. 31. Fluid-pressure hammers. -Relates to a machine in which ores,rock, cement, &c. are ground or crushed between reciprocating heads or stamps d, g which are caused to move towards or away from each other in a crushing-chamber 29 by fluid pressure exerted upon pistons secured to their stems. The piston c, Fig. 3, works in a cylinder b placed under, and in communication with, a pump k, the piston m of which is driven by a crank and connecting-rod from a driving-shaft s. The pump piston in moving to the right forces air through the port 14, the chambers 3, and the passage 2 into the chamber 1 in the cylinder cover from which it enters the cylinder b by lifting the valve 8. When the piston c has been pushed forward beyond the port 17, the additional air supply forces it onwards at a greater speed. The air on the opposite side of the piston is in the meantime forced out into the cylinder k through the ports 19, 18. The return stroke is effected in the same way by forcing air in upon the other side of the piston. The areas of the ports 14, 18 are adjustable by means of screw plugs 15 for the purpose of varying the stroke of the piston c. The piston-rod 9 is hollow and receives the shank 10, upon the end of which the crushing-head d is secured by a bayonet connection and a set-screw 13 ; at the rear end the shank carries, on a sleeve 21, a spur-wheel 11 by which it is rotated through a train of gearing from the driving-shafts. The cylinders and pistons at the opposite end of the machine are of the same construction, but made adjustable along the bed ; the pump piston is worked simultaneously by linkwork from the other pump, and the crusher head may be rotated in the opposite direction.
Patent GB-190123136-A (GB)
Title: Improvements in, and relating to, Friction Clutches.
Inventor: DRING JOHN
Filed: 1901-11-15
Granted: 1902-10-09
Abstract: 23,136. Dring, J. Nov. 15. Motor cycles; clutches.-Relates to a cone friction clutch normally kept in action by springs, and to means for disengaging the same from a distance. The invention is described in connection with a motor bicycle, but it is also applicable in motor cars generally. The hub a of the bicycle driving-wheel carries, on a free-wheel clutch, the chain-wheel c which is driven by the pedal crank axle ; it also carries a disc d to which is secured a conical shell i; the cone k, to which is fixed the wheel r, driven by the motor, is pressed by springs o into contact with the conical shell and thereby connects the wheel r to the hub. To disconnect the motor, the cone is pressed inwards by means of a nut t, screwed on the fixed collar s, which is turned, from any convenient point, by means of the Bowden mechanism described in Specifications No. 25,325, A.D. 1896, and No. 9206, A.D. 1901, [Abridgment Class Mechanism &c.]. Ball bearings are introduced between the nut and the cone, and between the abutment disc and the disc d. The wheel c as well as the wheel r may be driven from the motor, thus forming a two-speed gear.
Patent GB-190124996-A (GB)
Title: Improvements relating to Motor Road Vehicles
Filed: 1901-12-07
Granted: 1902-05-22
Abstract: 24,996. Lake, H. H., [Olds Motor Works]. Dec. 7. Motor road vehicles.-Relates to carriages propelled by oil engines, and comprises the construction of the vehicle frame and manner of supporting the body thereon, also change-speed and reversing transmission gearing, and certain features in the construction of the engines, together with the controlling-means therefor. Fig. 1 shows a longitudinal section through the vehicle. The frame consists of a central rigid portion 1 carried by downwardlyinclined springs 2, 2 attached to the front and rear axles 3, 4, the attachment at the rear being effected by clamps 12 which permit of adjusting the tension of the driving chain 9. The motor itself extends from front to rear of the frame 1, and contributes to its rigidity. Fig. 8 shows a cross-section through the vehicle body and frame passing centrally through the engine valve-chest, and Fig. 16 shows diagrammatically the automatic pump mechanism for supplying hydrocarbon from the fuel tank 53 to the carburetter 49. Fuel is caused to flow to the carburetter, whenever the engine is working, by the pumping action of a diaphragm chamber 55 connected to the crank chamber by a pipe 56, and thus subjected to the pulsating action of the air therein. The fuel is delivered from the valve chamber 58 to a receptacle 54, whence it flows to the carburetter. A lifter 67 is provided for replenishing the receptacle 54 at starting. For starting the engine a crank handle 83 is provided for revolving a countershaft which drives the engine crank shaft by means of a chain and a oneway clutch, which allows the motor when started to over-run the countershaft. The exhaust valve lever 29 is arranged to be moved at starting longitudinally on its fulcrum spindle at 30, so as to be acted on by a cam which keeps it open during the greater part of the stroke. The transmission gear is shown in Figs. 11 and 12. The driving chainwheel 87 in this is driven by epicyclic gearing from the shaft 7, Fig. 1, either at the low forward speed or backwards, and is driven direct at the high forward speed. To the chain-wheel are attached heads 88, 89, one carrying planet pinions 102 gearing with the internal wheel 95, and the other forming an internal wheel gearing with planet pinions carried by a head 96. The driving-shaft carries pinions 93, 94 gearing with the planet pinions, and the driving is forward or backward according to which of the heads 95 or 96 is held stationary by the brake straps shown. The forward fast speed is obtained by pressing the friction blocks 111, carried by spring arms 110 on the shaft, against the head 95 by means of the levers 112 acted on by the sliding wedge collar 115. The brake-straps are tightened by cams on a rocking shaft 118, the motion being transmitted to the straps by thrustrods contained in tubular tension rods 127.
Patent GB-190200494-A (GB)
Title: Improvements in connection with Railway Fog Signalling Apparatus
Inventor: WALKER ALFRED GEORGE
Filed: 1902-01-07
Granted: 1902-09-11
Abstract: 494. Walker, A. G., and Bailey, G. H. Jan. 7. Fog and audible signals.-The detonators 4 are contained in recesses 1<a> in a horizontal plate or magazine 1, mounted on a pivot 2, the detonators having recesses 15 to receive the projection 11 on the feed bar or pusher 8, which advances the detonators in succession into position on the rail. The bar 8 is connected by a rod 9 &c. to the ordinary signal lever, or may be operated independently. On the forward movement of the bar, its projections 14 fall over the inclines 18*, so that the projection 11 engages a detonate, which it then pushes forward on to the rail. On the return movement, the projections 14 rise over the pivoted triggers 16, and so disengage the projection 11 from the spent detonator, which is stopped by the weighted trigger 17 and, at the next operation, is pushed forward over the rail by the following detonator. When the detonator has not been exploded, the backward movement of the bar 8 is stopped when the detonator reaches the trigger 17, the bar remaining in engagement with the detonator. The movement of the magazine to bring the detonators successively into position to be fed by the bar 8, is effected by projections 12, 13 on the bar engaging the triangular projections or teeth 5 on the magazine. On the backward movement of the bar, the inclined face 12<a> of the projection 12 engages a face of one of the teeth 5, and effects a partial movement of the magazine. On the forward movement of the bar, the face 13<a> of the projection 13' engages another face of the same tooth, and completes the feed movement of the magazine. The apparatus is protected by a cover 6. In a modification, the magazine is arranged vertically, and its feed movement is effected by three inclines on the bar 8 engaging teeth 5 on its circumference, a check pawl being employed to prevent backward movement. This form can also be adjusted vertically to the height of the rail.

Title: Improvements in and connected with Furnace Charging and Distributing Apparatus.
Inventor: BLECKLEY HERBERT SANDERSON
Filed: 1902-03-01
Granted: 1902-08-28
Abstract: 5193. Sleekly, H. S., Atherton, T., and Massey, E. March 1. Charging; indicators.-The charging - hopper, which receives iron ore, coke, &c. from tipping- skipa b, is made with an upper cylindrical compartment i, the lower part k of which is movable to allow the charge to escape round the fixed cone into the lower part p of the hopper, whence it is discharged by an ordinary movable cone q. The sleeve k and cone q are operated by power cylinders o, v or other motive appliances, acting through levers m, s, and the valves of these cylinders are provided with interlocking- gear, shown separately in Fig. 7, so that both cannot be opened together. Both valves are operated from the engine room below by means of a lever 12 adjacent to the winding-engine which elevates the skips, the movements of this lever being communicated by rods and bell cranks, or other suitable mechanism, to a shaft 17, Fig. 7, having arms 18, 19, which operate the valve spindles 20, 24 of the respective cylinders v, o. These arms engage recesses in blocks attached to the valve spindles, but the upper jaws of the blocks are curved as shown, so that when one valve spindle is depressed, the end of the other arm (18 or 19) engages with the curved portion on the other valve spindle and locks it. To indicate the height and distribution of the charge in the furnace, a number of sliding rods z are arranged round the top of the furnace, one only being shown in Fig. 1. These rods are attached to chains passing over guide-pulleys to winding-pulleys 5 in the engine room, there being a separate pulley for every rod. The pulleys are mounted on their operating-shaft as shown in Fig. 6, being turned to raise the rods by arms on the shaft. On lowering them, however, as soon as each rod touches the surface of the charge in the furnace, the corresponding pulley ceases to rotate. The pulleys also operate miniature rods 35 in a model of the furnace top situated in the engine room, and the position of the rods 35 corresponds with those of the rods z. Models 36 and 37 of the cone and sleeve of the charging-hopper are also connected to the levers operating the actual cone and sleeve, so as to indicate the positions of the latter. The pulleys 5 are operated by motor apparatus the controlling-lever 38 of which is so arranged in proximity to the lever 12 controlling the charging- hopper, that the charging-cone q cannot be opened until the rods z have been raised clear of the charge already in the furnace.
