Title: Improvements in Roundabouts or analogous Devices for Purposes of Amusement.
Inventor: LEWIS JAMES
Filed: 1899-05-11
Granted: 1899-09-09
Abstract: 9936. Lewis, J., and Davies, G. R. May 11. Roundabouts.-The improvements, though applicable to various kinds of roundabouts and to other analogous devices for amusement, such as switchbacks, are more especially applicable to those carrying seats representing horses, and are such as to suggest the idea of racing. In the case of a circular roundabout driven in the ordinary way, each section, Fig. 3, of the roundabout supports, say, a couple of platforms which revolve about independent axes i, i, carry the rotating horses. The horses, as well as the platforms, are operated by suitable bevel gearing such as that shown, so that, in general, compound circular or cycloidal or epicycloidal motions are given to the horses. In addition, each horse is rocked by being pivoted at the top of the vertical spindle f, and by means of depending arms g' bearing against a rotating eccentric flange e'. The rocking motion may be obtained also by replacing the arms by an eccentric-rod connected to a bracket on the horse. To give the horses a slight turning or angular movement to the right or left as they pass from the inside to the outside position, the holes in the gear-wheels f, f<2> may be made eccentric. The gearing for the platforms may be overhead, in which case, the horses are supported on depending rods.

Granted: 1900-06-14
Abstract: 12,400. Fisher, I. H. June 14 Tip-carts.-Relates to a cart for mixing, transporting, and dumping concrete, mortar, &c. A drum, made in two halves 3, 3<a>, hinged together at 18 and fastened by spring catches 20 which engage a tongue 19, is secured upon an axle provided with road wheels 1. The shafts or handles 8 of the cart have bearings which fit over necks formed inside the bosses of the road wheels, and between them and the ratchet-wheels 5, also secured to the bosses. The half 3<a> of the drum has pivoted on each side a pawl 6, which by engagement with the ratchet-wheel causes the rotation of the drum as the cart moves forward ; the pawl is thrown out of action, when the charging-door 23 is opened, by a pin on the door acting against the tail 6<a> of the pawl. The door, when open, rests upon a cross-bar 37, supported by brackets on the ends of the shafts. When it is required to dump the contents of the cart, the catch 15 is raised to liberate the spring bolt 10, which is then shot forward into the path of the catches 20; these, as the drum moves round, engage with it, and are moved apart to liberate the tongue 19 ; as the axle continues its rotation, the half 3<a> of the drum moves with it, and leaves behind the half 3, which slides outwards over guideways formed on the shafts, and in so doing pushing back the bolt 10 to its retracted position ; at the same time the pin 29, acting in conjunction with a hook 30, draws the pawl out of gear with the ratchet-wheel. The pawl may be held out of gear by causing a notch formed in the hook to engage with a fixed stop 32.

Abstract: 19,650. Cooper, S. Sept. 30. Clutches ; driving-mechanism.-Relates to clutch driving-gear for bicycles, motor cycles, &c. arranged to give a fixed or free wheel. The hub 2 carries a collar 4 with ratchet teeth which engage clutch blocks 13 working in recesses in the looselymounted chain-wheel 8, and kept in place by plates 3, 9. The hub also carries a collar 16 on which slides a cup 17 with a bevelled flange 19. A forked spring 22, fixed to the stay 21, engages a groove on the cup, and forces it inwards so that its flange acts on the clutch blocks 13, and retains them in contact with ratchet teeth, thus forming a positive connection between the hub and chainwheel. The cup can be moved outwards by operating a lever mounted on the top bar of the frame and suitably connected by rods to a lever 28 engaging a bolt 32 carried by the spring 22. When the cup is moved outwards as shown, the clutch blocks are free to rise over the ratchet teeth, thus giving a free wheel. The cup may be operated through cords &c. A spring band encircles the clutch blocks, so as to keep them in operative position. The chain adjustment is preferably fitted to the bottom bracket, but may be applied to the rear axle by using swinging stays on which the spring 22 and the operating-mechanism are mounted so as to move with the wheel.

Granted: 1901-02-16
Abstract: 10,063. James, R. W., [Menns, W. K.]. May 31. Striking-mechanism for announcing the nautical watches, the hours and the half hours being struck by a single hammer. A cross-arm 10 on the minute-hand arbor 11 bears a pair of pins 12, 13 to lift every half hour the warning-piece 15 on the last wheel of the train by acting on a branch 14. In turn the warning-piece lifts a detent 16, resting on it, from a pin 25 on the preceding wheel 26, and with the detent the rackhook 34 from the end of the rack 35. The rack falls till its arm 36 feels the snail (not shown), which is divided into four steps, and is driven by motionwork at one fourth the speed of the minute-hand. When the cross-arm lets the warning-piece drop, the gathering-pallet 33 resets the rack, and the rack book and detent drop into their initial positions. The striking-wheel (not shown), which turns a quadrant for each revolution of the gathering- pallet, bears four pairs of pins to lift the hammer 29 by catching a pin 21 which projects from its arbor 18. A spring 19 bearing on a pin 20 throws the hammer to give the blow on the gong. At the half hours the hammer is prevented from striking the second blow as follows :-A long lever 45, which has a spring branch 47, is lifted against a spring 32 on the hammer arbor 28, because a pin on the first wheel 38 of the motion-work puts the branch in tension and the rack returned to its initial position detaches a detent from the lever. Owing to the end thrust of the pin on the hammer, the lever does not fall again till the next full hour, when the hammer is lifted again.

Title: Improvements in Speed Changing and Clutch Mechanism for Motor Vehicles.
Inventor: RENAULT LOUIS
Filed: 1901-11-09
Granted: 1902-09-11
Abstract: 22,664. Renault, L. June 6, [date applied for under Sec..103 of Patents &c. Act, A.D. 1883]. Motor road vehicles.- Relates to clutch, braking, and speed changing and reversing mechanism for motor vehicles. Fig. 4 shows in plan, and Fig. 5 in vertical section, a form of gearing giving three speeds and reversal. Fig. 2 shows a transverse section through one end of the gear. The motor shaft a is capable of being connected through the medium of the cone clutch b, c with the shaft d. On this is carried loosely a pinion s, which is permanently connected by a Cardan joint at u with the driven shaft v. Motion is communicated in various ways from the shaft d through a parallel shaft w to the pinion s. Firstly, provision is made for connecting and disconnecting the clutch b, q and applying a strap brake on the drum t by operating a single lever 22. The movement of this lever first acts by a cam 23 on a rod 24 carrying a fork 27 whereby the clutch can be disengaged in opposition to the spring e. By a further movement, the lever 20 may then be operated, whereby the brake strap is tightened. The changes of speed and reversal are produced by sliding the double pinion i into different positions along the shaft d, and concurrently moving the shaft wand another shaft carrying an idle reversing-pinion bodily nearer to or further away from the shaft d, so as to put the pinions in gear. For shifting the pinions i, a shaft k, with cam.grooves by which the fork j can be adjusted, is provided. To permit of the shifting of the shaft w, and the reversing-pinion, in the manner indicated, the shafts are mounted in eccentric bearings x, y. The partial rotation of these eccentrics is effected by racks such as 2, Fig. 2, acted on by cams m, n on the shaft k. All the speed changes and reversal are under the control of a single rack 5, by the movements of which the shaft k can be made to assume different positions. To allow for the teeth not being exactly opposite, the movements are not absolutely compulsory, springs p being interposed as shown. The arrangement is also so disposed that at the highest speed no intermediate pinions are in use, the pinions i being directly clutched to the pinion s.
