Trimimings.-An apparatus for covering, with a leather or like strip 67, the moulding 68 shown in Fig. 10, comprises means for positioning the cover strip about the moulding, for engaging said cover and allowing prongs on the moulding to pierce the cover, and for turning the prongs to secure the cover in place. In Fig. 8 is shown the covering strip 67 in successive stages of being wrapped round the moulding 68, which is provided with prongs 70 for piercing the strip, as shown at 70<a>, and for being clenched over, as shown at 70b. The moulding is also provided at intervals with plates 71 having upstanding nails 72 thereon. The guide 27 for the covering strip is shaped to embrace the strip and turn it into a tubular shape round the moulding as it passes to a pair of oppositely-inclined grooved wheels one only of which 47 is shown. These wheels co-operate with a wheel 21 which has a cylindrical grooved portion corresponding to the shape of the moulding. The groove may be in a cylindrical block fixed in the periphery of the wheel 21 and the block may be die-cut to emboss the surface of the covering strip such as leather while being applied. Discs 35 are carried by spring plates 31 and have bevelled surfaces which project over the grooves in the wheel 21 and are slightly spaced apart to allow the passage of the upstanding nails 72 in the moulding. The upstanding prongs 70, however, are turned inwardly bv the bevelled surfaces, having been previously forced through the cover and slightly bent to a vertical direction from a slightly inclined direction. The nails 72 in the strip pass through a tapered guide to a slot in a wheel 51 which further clenches the prongs 70 so as to deeply embed them in the cover. Power is only applied to the shaft 14 by a crank 23 or any other suitable means, the wheels 47, discs 35 and wheel 51 being all frictionally actuated. The core material of semi-hard rubber, carrying a metallic clamping member 69 provided with the prongs 70, is supplied on reels, as also is the covering material.

Abstract: 672,171. Cycle driving - mechanism. WINDLE. J. F. Aug. 3, 1950 [July 31, 1950], No. 19078/50. Class 136(ii) A driving mechanism for bicycles, tricycles or similarly propelled vehicles comprises a main free wheel driving gear 2 which drives by means of a chain 3 a gear 4 of the fixed wheel type secured to the driving axle 5 of the vehicle, a secondary free wheel driving gear 10 in driving engagement with the chain 3, and reciprocating means operatively connected to the gear 10 and reciprocable as a result of the movement of the body of the rider when the vehicle is in motion to effect rotation of the gear 10 to drive the chain 3. The gear 2 is also operable by pedals independently of the gear 10. The gear wheel 10 is mounted on a stub shaft 9 slidably mounted in slots 7 formed in brackets 6, spring means urging the gear 10 into the position shown in Fig. 1. The teeth of the gear 10 are in mesh with the teeth of a jockey wheel 11 which is mounted on a stub shaft 12 slidable in slots 13 in brackets 14. The teeth of the jockey wheel 11 are formed by the links of an endless chain wound on a supporting hub. The saddle pillar 20 is slidably mounted in the cycle frame 1 and is urged upwardly by a spring 21. The shaft 9 of the gear 10 is attached to one end of a cable 25, the other end of which is attached to a bracket 24 provided on the saddle pillar 20. The weight of the rider in the saddle causes gear wheel 10 to move forwardly and the interengaging teeth of the gear 10 and the jockey wheel 11 produces a counter clockwise rotation of the gear 10 which will drive the chain 3. On release of the weight of the rider from the saddle the gear 10 is returned by spring means to the position shown in Fig. 1. To permit free movement of the gear 10 the stub shaft 12 of the jockey wheel 11 is mounted on a pivoted rod 15, Fig. 2, so that it may oscillate in a' vertical direction within the slot 13. In a modification applicable to a tricycle, as shown in Fig. 3, the oscillations of the saddle pillar 20 are transmitted to the stub shaft 9 of the gear 10 by a compression spring 28 and a curved link 29. The gear 10 is urged rearwardly by a spring 30 and guided in its sliding movements by a rod 31 which is pivotally connected to a crank 33. The stub shaft 12 of the jockey wheel 11 is carried by links 35 pivoted on the stub shaft 9 of the gear 10. The ends of the shaft 12 project through slots 36 formed in brackets 37 which are pivoted at 38 to the tricycle frame 1.

Abstract: 1,182,133. Coating pipes; coating apparatus. RAYMOND INTERNATIONAL Inc. 26 April, 1967 [12 May, 1966], No. 19195/67. Headings B2K and B2L. [Also in Division F2] Mortar is deposited in pipes and trowelled using a resiliently compressible trowelling means, an inwardly projecting ring being applied to the end of the pipe so that the trowelling means is restrained in size on entering the pipe. In Figure 1 motor-driven equipment 11 is advanced through a pipe 10, the equipment having a distributor head 12 for discharging mortar in plastic condition onto the interior of the pipe to form a rough lining 13. A frusto-conical resilient trowelling element 14 formed of sheet metal is pulled through the pipe by a rod 15 attached to the mortar distributing equipment. The trowelling element is formed with a plurality of leaves 16 and 17 the edges of which slidably overlap at 18 so that the trowelling elements become constricted in diameter upon entering the pipe. A ring 20 is clamped by thumb screws 21 onto the entry end of the pipe so that a flange 22 on the ring defines a diameter equal to the desired smooth lining diameter. The ring causes the trailing elements gradually to be restricted to a corresponding diameter. A ring is similarly clamped on the other end portion of the pipe so that a trailing edge 14a of the trowelling element is retained against an expansion until it passes the edge of the flange on the ring.

H. ; 329, Cortland Avenue, Detroit, Michigan, U.S.A.) July 6, 1935, No. 19351. Convention date, Oct. 8, 1934. [Class 83 (iv)] Angular-bending.-In a machine for bending strip for vehicle window frames &c. in which a pressing tool irons the strip about a rotating die, means is provided for moving the geometric centre of the die relatively to the centre of rotation of the table to prevent injury to the parts when using a non-circular die. A die 18 of suitable contour is mounted on a table 19 slidable in a guideway 22 in a track 10 rotated from a shaft 17. A guideway 31 in the bottom of the table engages a slider 30 on a pin 29 adjustable by a hand screw. The position of the pin 29 is adjusted so that the motion of the die, due to the guideways 22, 31 is away from the presser 52 as it approaches a part of greater radius and vice versa. The table is rotated from an electro-motor 12 through a clutch 13 controlled by an air cylinder 97. The pressing tool 62 is controlled by an air cylinder 65. Hand operated valves 108, 109 control a main air valve 102 and the supply to cylinder 97. Clack valves 121, 122 and a valve 110 operated by stops 112, 113 on the table 19 are fitted. Operation. The strip 37 is secured to the die 18 by a clamp 51. The valve 108 is operated and air pressure from supply 101 operates piston 104 to turn valve 102 and admit pressure to cylinder 65 to project the ironer against the work. The valve 109 is then operated to engage the clutch 13 causing the table to rotate. When the concave part of the die has passed the pressing tool 62 a clamp is dropped to hold this part of the work against the die stop-motion. When the table has rotated 350‹, the cam 113 operates valve 110 to admit air to cylinder 105 to reverse valve 102 to stop the table and to allow a small piston to retract piston 64 and ironer 52. The valve 109 is again operated, the clutch is re-engaged and the table is finally stopped by cam 113 at 360‹ rotation and the strip is removed. To stop the machine in an emergency, the lever 111 of valve 109 is lifted and air passes through valve 122 to cylinder 98 to disengage the clutch and throw the valve 102 to exhaust position.
