Title: Improvements in Means for Propelling Bicycles and Analogous Vehicles.
Inventor: MALLETT FRANCIS WILLIAM
Filed: 1897-07-20
Granted: 1897-09-04
Abstract: 17,089. Mallett, F. W., and Hulbert, W. A. July 20. Driving-mechanism for bicycles &c. Thrust-rods enclosed in the lower back forks are reciprocated by projections on the driving-wheels, clutches imparting motion to the rear driving-wheel. Two thrust-rods D, provided with flexible ends D<1>, D<2>, are arranged in the lower back forks A<2> and acted on by returning and cushioning springs D<4>, D<5>. These rods are reciprocated by spurs or projections C<2> on wheels C' fixed on the pedal-crank axle, the motion being imparted to the rear driving-wheel axle by clutches. The clutch preferably employed consists of a ring F, mounted loosely on the wheel hub, and connected by a spring arm F' to the flexible end D<2> of the thrust-rod D, and by a link F<4> to a clutch block F<5> acting against an annular flange E<6> formed on the hub. A movement of the rod D first slightly rotates the ring F, which causes the toggle link F<4> to press the clutch block F<5> into firm contact with the flange E<6>, the further movement of the rod then imparting rotary motion to the flange and hub. The wheels C<1> are arranged to act alternately, each wheel being provided with seven spurs C' to give seven reciprocations to the thrust-rod for each revolution. To cause a braking action between the clutch block F<5> and the flange E<6>, when desired, wedges G are provided, which may be inserted between blocks A<6> fixed to the casings A<4> and the clutch blocks F<5> when the blocks are nearing the end of their stroke. The wedges are carried by bell cranks G<1> actuated by rods G<2> passing through the framing to a handle located near the handle-bar. The flexible ends D', D' of the thrust-rods are made to fit the stays and casings accurately, and they are guided by rollers a', a<6>. Casings A', A<3> and A<4>, A<5> are fitted to the ends of the stays A<2> to enclose the gearing. A brake arrangement C<5>, C<6>, a<1>, a<2> is provided to prevent the pedal-crank axle from being rotated in the wrong direction, as this would destroy the ends of the thrust-rods. When descending hills &c. the cranks remain stationary and serve as foot-rests ; to exert a braking effect by means of the wedges G forward pressure on the cranks is necessary.

The tube A, Fig. 1, drawn in an ordinary manner to a uniform bore, is further drawn upon a mandrel B which has reduced parts b, b<1> corresponding to the required thickened portions of the tube. The tube and mandrel are now subjected to the action of a releasing-machine, and the mandrel is afterwards withdrawn so as to leave a tube of uniform internal bore, as shown in Fig. 3, but with thickened ends. If the tube is required to be of uniform external bore, it is subjected to a further drawing on a loose mandrel, the bulb B' on the original mandrel being in this case dispensed with. To obviate the waste formed by cutting-off the closed ends A', the mandrel, Fig. 17, may have a squared end for receiving a stem D, between which and the screwed-on sleeve E the bent-over flange A<3> on the tube is secured. The shaped parts may screw on to the long plain part of the mandrel, and the grooves e,f in the shaped parts are of use in withdrawing the mandrel from the tool. Tubes of tapering thickness may be made in the same manner by employing corresponding mandrels.

Abstract: 14,019. Buchanan, R. Aug. 4. Drawings to Specification. Processes for reduction of grain.-Relates to a process for flour milling, and the arrangement of the plant therefor. The main object of the process is to reduce the amount of "break flour," the bulk of which, the Specification states, is not produced in the break, but is the result of the violent action-the products are subjected to in the various scalping and dressing machines commonly employed. These machines are now dispensed with, and the products are separated by air-purification, with or without a preliminary sifting which separates from the products of the first break the coarse feed for the second break. The air purifier separates the remaining products into "tailings," which consist of finer feed for breaks or fluted rolls ; into "throughs," which consists of coarse and fine semolina, coarse and fine middlings, dunst, and heavy flour; and into products separated by The air current, consisting of light branny particles, light flour, and dust. These products, thus separated, are then treated as in the ordinary process.
