摘要： 311,839. Francois Cementation Co., Ltd., Degenhardt, W. R., Fraine, A. F. de, Bicknell, R. A. W., and Bicknell, A. Jan. 23, 1928. Digging-apparatus. - In a rockabrading machine for tunnelling and shaft-sinking, of the kind comprising a rotary member provided with loosely-pivoted tools which, during rotation of the member, move outwards into operative position under centrifugal force, the rotary member is carried by a tool arm operated so as to cause the tool to move in a spiral path over the face of the tunnel or shaft. Pivot pins B, which may have rotatable sleeves B , are carried by spaced discs C and ring-shaped cutters A, with integral teeth, are mounted on the pivot pins and have an internal diameter substantially larger than that of the pivot pins so as to be movable outwardly under centrifugal force. In modified forms, the ring-shaped cutters have renewable radial teeth or have plain peripheries of wedge-shape or rounded section. Radial slots or elongated holes may replace the circular bore of the cutters and more than one cutter may be mounted on each pivot pin, cutters on adjacent pins being staggered. The discs Care rotatably supported by a frame D carrying a motor which drives the discs through ropes. The frame D is fixed to an inner shaft F which passes through an arm F', the arm F being universally pivoted and controlled as in Specification 297,137 to move the cutters in a spiral path to cover the entire face of the tunnel &c. A ball f , by which the spiral movement is communicated to the device, has peripheral grooves engaged by forks on the shaft F and a part f of the gear which effects the spiral movement, whereby the frame D is rotated so that the axis of the cutter head always lies radially of the tunnel. Current is supplied to the motor through collecting rings e. Specification 238,262 also is referred to.

摘要： 297,137. Francois Cementation Co., Ltd., Degenhardt, W. R., Fraine, A. F. de, and Bicknell, R. A. W., and Bicknell, A., (Representatives of Bicknell, R. H.). June 14, 1927. Digging apparatus.-In an excavating, tunnelling or shaft sinking apparatus of the automatically controlled type described in Specification 238,262, wherein an abrading tool is mounted on a universally-pivoted arm and is moved so as to act on all parts of the working face, the tool is so guided that the product of its linear velocity and active area is approximately constant so that an approximately constant volume of material is removed per unit of time. Preferably the active area of the tool is constant and the velocity approximately constant. As shown, a wheeled frame A carries brackets B in which a traversing arm B is universally pivoted, the arm B carrying a cutter B operated percussively by liquid-wave transmission ; the liquid is supplied from generators C, on a separate truck C , through pipes C , C , C , C', C , the pipes C , C', being arranged to pivot about axes aligned with those of the universal mounting of the arm B. The arm B is balanced by a counterweight B , preferably built up of lead disks, and has at its rear end a ball-shaped member B engaging a socket D, Fig. 6, in a block D' slidable in radial guides in a rotary member D carried by a tubular shaft D , while the block D engages a crank pin D on a disk D carried by a shaft D ; the member D is driven from a motor D through belt gearing and worm gearing D', while the crank disk D is driven through differential gearing d , d , d , d , whereby the cutter B is given a spiral motion. A clutch may be provided between the gears d , d whereby either gear may be engaged with the shaft D . The linear velocity of the cutter is maintained constant by means of gearing d , Fig. 11, driven with the member D and driving a disk D which, through a connecting rod d , moves a belt D on tapered pulleys D , D through which the drive is communicated from the motor D ; alternatively, the rod d may control a variable resistance by which the speed of the motor is varied. A rearward extension of the shaft D acts through worm gearing E , E , to drive a cam E which, after each half cycle of the arm B, acts through a lever E , pawl levers E , ratchets E', and pinions E to drive pinions E engaging racks, whereby the machine is advanced. Debris is removed from the working face by a scraper G carried by a frame G which is reciprocated through a lever G from a cam G moving with the member D , the mechanism being turned so that the scraper always clears the tool B ; the frame G has rollers cooperating with pivoted inclined members G' whereby the scraper is lifted over the debris in its forward stroke. The scraper delivers to a sectional conveyor comprising hinged plates F carried by reciprocating members F driven from a motor F through a belt F , reducing gearing and a connecting rod F . The tool comprises annular edges b' divided by radial and diametric grooves b of variable depth the grooves being continued so that peripheral cutting edges B are formed. During operation, shocks are taken up by toggles Ex engaging the. turnel wall. The cutter may operate in circular paths, being moved radially after completing each circle. Other than circular tunnels may be formed; to form elliptical tunnels, the machine may act at an angle to the direction of the tunnel.

摘要： 309,518. Francois Cementation Co., Ltd., Degenhardt, W. R., Fraine, A. F. de, Bicknell, R. A. W., and Bicknell, A. Jan. 9, 1928. Drills. - In tunnelling-apparatus wherein an abrading tool is moved over the rock &c. to form a channel so as to leave a central core &c. which is then blasted &c., the tool being continuously moved upon a suitably shaped guides rail &c. during the abrading operation, the guide rail &c. is carried by a structure supporting the portion of the tunnel already formed. In Figs. 1, 3 and 4, an arcuate or other guide rail C is attached to segments C secured to the tunnel lining C , shock absorbing material being interposed. A frame B is slidably supported by means of rollers B engaging the inner and outer surfaces of the guide rail, the frame being rearwardly extended and provided with a further roller B engaging the tunnel lining. Cables B attached to the frame, pass within the guide rail and over pulleys B , B , Fig. 4, at the ends thereof to a winch B reversed automatically or by hand, whereby the frame B is traversed; alternately, a motor on the frame may drive members engaging teeth or a friction rail carried by the guide rail &c. to effect the traversing. A block A is slidably adjusted on the frame B by a screw AS and carries a pillar A on which is mounted the body A of a percussive tool of the hammer type, operated by fluid wave transmission ; alternative inlets A are provided for the fluid, the inlet not in use being plugged. A serrated wedge A' is secured to the rear of the tool body and co-operates with a second serrated wedge A' to take up rearward thrust of the tool; the wedge A' is laterally adjusted as required by means of a screw A carried by the frame B. Shock-absorbing material may be provided behind the. wedge A , and the wedges may be replaced by a plain thrust-block. As the cut extends, the tool may be extended by interposing distance pieces a, Fig. 7, secured by pins or bayonet joints; a detachable yoke. member A‹ may be provided to support long distance pieces. The tool may be adjustable radially and where other channels are required at different radial distances, the frame B may carry an inwardly extending radial arm on which the tool is adjustably mounted. The segments C' may extend close to the smooth wall of the tunnel to prevent escape of grout forced behind the lining; bags of sand &c. may form an additional seal. In a modification, Fig. 8, the tool body A' is carried by a platform D and slidable in a trunnion D rotatable in a bracket B on the frame B; a link D connects the platform D to the bracket B , and an arcuate rack D' on the platform engages a pinion D rotatable by a hand wheel D through worm gearing D to adjust the platform D, the arrangement being such that the cutter A advances in a straight line parallel to the axis of the tunnel. A fluid-wave generator D and motor D are carried by the platform. The frame B is held on H-tracks C by inner and outer rollers B and radial rollers B x and carries a seat for the operator and also a motor E acting through worm gear E and pinions E or friction wheels to traverse the frame B. Slip-clutches may be provided in the traversing gear. The iool body may have a curved shield on each side. Rotary cutters may replace the percussive tools. The machine may cut a complete circle or a segment only, as against the roof when tunnelling below rivers to prevent damage to the roof when blasting. Reference has been directed by the Comptroller to Specification 291,880.
