Mud and rain guards.-A splash guard is permanently or detachably affixed to the rear of a boot or shoe so as to be moved up or down into operative and inoperative position so as when not in use to lie against the heel portion of the upper. In one form, Fig. 5, a shell portion B ornamented as desired is clipped or otherwise secured to the heel of the upper of a, boot or shoe and.carries, on a strip b, a number of vanes A, slots a in which are guided by pins b secured to an outer plate B of the shell B, so that, as the strip b is moved up or down in a slot b in the plate B' by a knob b attached thereto. the vanes a are operated to open or close in the manner of a fan. In a modified form, Fig. 6, a series of vanes A are carried on a pivot a adapted to be moved in a slot b in the outer plate B of a shell B adapted to be clipped to the rear of the shoe upper, and the vanes are formed with shoulders so as to be opened out fanwise when the shoulders contact with the edge of a slot in the shell B when the pivot a is moved upwards. A second series of vanes A carried on a common pivot a' and operable by a knob a carried by a U-shaped stirrup is provided to form a lower guard. The vanes are given an outward set from the heel to avoid contact with the wearer. In alternative forms, the vanes may project spproximately horizontally from about the middle of the depth of the upper at the heel and are bent to lie along the upper in the retracted position, or the guard may be retracted between layers of the upper through a horizontal slot formed in the outside layer.

    • 644,102. Printing-machines. COOK, E. R. Jan. 22, 1948, No. 1988. [Class 100 (ii)] In a printing-machine in which one or more impression cylinders 9, 9a are carried at their ends by endless travelling elements, e.g. sprocket chains by which the axes of the cylinders are caused to move in an orbit within which a stationary type bed is mounted, the cylinders are guided by a pair of complementary continuous tracks 5, 6 at each side of the machine and the cylinders are rotated by rollers 18 engaging with a fixed driving track 17 corresponding in shape to and spaced from each continuous guide track 5, 6. The machine comprises main frame side plates 1 braced by struts 2 and embraces a sub-frame assembly, held by flanged bolts 3 to the side plates, and which carries the stationary type bed 4 and also the guide tracks 5 and 6 one pair at each side of the bed 4. Spaced from the guide tracks 5 by bolts 8 are the fixed driving tracks 17 formed by teeth in plates 7 or comprising an endless fixed chain 17 which engages and causes to rotate the rollers 18 shown as sprocket wheels secured on the cylinder shaft drawn over the fixed chain 17 by links 25 attached to travelling chains 19. The cylinders 9, 9a have grippers to pick up and release the paper sheets. The travelling chains 19, one of which is positioned at each side of the machine, are driven by sprocket wheels 20 on a driven shaft 22. Shaft 22 carries a roller which transfers ink to rollers 10, 10a, situated between the impression cylinders and similarly drawn by links 28 attached to the travelling chains 19. The impression cylinders are held away from contact with the transfer roller by the portion 5a, 6a, Fig. 4, of the tracks 5, 6 while the inking rollers travel in the portion 5b, 6b enabling them to contact the 'transfer rollers. The tracks 5, 6 also guide the impression rollers into engagement with the bed 4, the axial alignment of the impression cylinders being effected by rollers 15 on the ends of the impression cylinder spindles which engage rails 13 inwardly projecting from the side plates 1. For two colour work two type beds may be arranged in series with ramps fitted in the guides so that the rollers contact only their corresponding type bed. The transfer roller 29, Fig. 5, over which the inking-rollers 10, 10a pass, is supplied with ink by a supply roller 32 mounted on an arm 33 oscillated by a rod 36 from a cam mechanism 38-41 driven from the machine and synchronized therewith so that the arm swings towards the roller 29 before the rollers 10, 10a reach it. In the other direction of swing, the roller 32 contacts a doctor roller 44 which revolves in an ink duct, and at each swing an extension 50 of the arm 33 engages an arm 47 so as to push it anticlockwise and a pawl 48 thereon engages a ratchet wheel 49 which rotates the roller 44 one step. In a modification the inking mechanism comprises an ink slab situated inside or outside the path of the cylinders 10, 10a and the inking rollers 9, 9a contact the slab as they pass either by the force of gravity or by spring action. To enable the inking rollers to be coated with ink before printing is commenced and without the type being inked a forme chase 55, Fig. 3, on the type bed is normally displaced from the path of cylinders 9, 9a and rollers 10, 10a by means of springs 66 mounted on a series of pins 65 screwed to the chase and which extend through the type bed 4. The chase is moved into operative position by a hand lever which through parallel linkage moves four wedges 57 to engage in slots in lugs 56 depending from the chase 55 which is thereby moved, against the pressure of springs 66, towards fixed stops 67 to render the inking roller effective.

    • 8738. Sayer, R. C. April 29. Wheels with motors.-Relates to fluid-pressure motors of the impact-wheel type, specially adapted for use in combination with the wheels of road vehicles. An important feature of the invention consists in varying the power and speed by varying the distance from the axle at which the fluid pressure is caused to act upon the vanes of the rotor, and this principle is applied either to single motors or to two or more concentric motors. Fig. 2 shows a section through a pair of concentric motors arranged as a wheel to run on roadways, and Fig. 4 is a transverse partial section. The fixed axle a carries a fixed spherical chamber a fitted with any number of valves a , through which the fluid pressure is admitted to peripheral chambers f, by means of which it is directed against several series of vanes or buckets g carried by a semi-spherical rotor h. The valves a are arranged in pairs, one set forward and the other for backward rotation, and the several pairs of valves are disposed at varying distances from the axle. These valves are actuated from a lever e through a central shaft e and chain gearing, in such a manner that they are opened in succesion, commencing at the one nearest the axle. Attached to the rotor h is a hemispherical chamber j, communicating through suitably-arranged ports with the chamber a and furnished with a number of pairs of valves j arranged similarly to the valves a and actuated from a lever a through a sleeve a and chain gearing. Through the valves j , the fluid pressure enters chambers j , which direct it against valves or buckets k on a second concentric rotor l. The chambers f, j are, in each case, followed by a series of expansion chambers f , Fig. 4. In the arrangement described above, different powers and speeds may be obtained, not only by adjusting the valves, but also by arranging that one or the other or both of the motors shall be operative. For this purpose, the rotor h may be connected either with the rotor l or with the fixed axle a, or the two rotors may be disconnected by means of a movable key c . This key is actuated from the double piston of a fluid-pressure cylinder b, the admission of fluid pressure to either end of which is controlled by a tap a actuated through a rod d from the lever d . The minimum power is obtained by connecting the two rotors together ; the power is increased by connecting the rotor h to the fixed axle ; and the maximum power is obtained by freeing both rotors. The application of the invention to a single motor having the form of a sphere flattened at one end is also described, and it is stated that the motor may have a cylindrical shape. An arrangement suitable for lower powers is described, in which fixed valves such as a are dispensed with, and a valve carried by a movable arm is brought opposite ports arranged on either side of a central line and at varying distances from the axle.
