IPC: B23B41/00
Filed: 1923-05-25
Abstract: 220,400. Kitson, H. V. May 25, 1923. Boring-bar machines; boring and turning mills.-Wheel centres and the like are machined on a vertical turning and boring mill having an annular work-table rotating about a vertical axis, a boring-bar axially movable in relation to the table, and tools independent of the boring-bar, the majority of the tools being provided with automatic stops. The boring-bar is advanced through the table from above and is supported below the table, and the bar and the table are positively rotated in opposite directions. A back-toback machine is provided comprismg two work-tables 28 having clamps 31, 31a for the work. Each table is independently driven from an electric motor or a belt pulley 49 through a clutch 54, horizontal shaft 48, vertical shaft 43 and spur gear 45. The boring-bar 35 is also driven from the vertical shaft 43 through a clutch 50 and gearing 42, 41, 40. The boring-bar is provided with a two-speed and reverse feed through two clutches on a shaft 65 and a rotating nut 70. The slow feed is obtained from the vertical shaft 43 through spur gears, a vertical shaft 62, and skew gears, and the fast feed is obtained direct from the power shaft 48. The slow and fast feed clutch is controlled by a hand lever 79 or may be automatically tripped by a nut on a power-driven shaft 83. A hand lever 82 controls the clutch for reversing the feed, and a hand-wheel 95 is provided for feeding by hand. Eight tools A - - H, Fig. 7, are carried in separate tool-holders, all except two, B and G, being fitted with automatic feed and stop motion in addition to the hand gear. The automatic feed for the tools is obtained through screw-andnut gearing driven through clutches from vertical shafts 101, 163 gearing with the toothed ring 45 on the work-table. The tools A, B are carried by a common vertical slide 112 but are on independent horizontal slides 114, 113. C, Dare on independent vertical and horizontal slides, and E, F are on a common vertical slide 171. The tools G, H, Fig. 22, for working on the underside of the boss of the work are carried in holders within the annulus of the work-table. The tool G is fed vertically by a hand-wheel 194 through shafts 193, 198 and worm and screw-and-nut gearing, and is fed radially by the hand-wheel 195 through shafts 196, 191 and worm gear. The tool H is mounted in a holder 199 traversed horizontally in a slide, 200 by rack-and-pinion gear 201 actuated either by a hand-wheel 205 or automatically by a cam 213 rotating with the work-table and operating a pawl and ratchet gear. The slide 200 is moved vertically by means of a hand-wheel 208.

Title: Improvements in and relating to Signalling Appliances for Collieries and the like.
Inventor: SAMSON JOHN
IPC: B66B19/06
Filed: 1916-10-02
Abstract: 108,397. Samson, J. Oct. 2, 1916. Order apparatus.-An electrically operated signalling appliance for collieries &c. has a pointer on a spindle 2 moved step by step by the action of a pawl u on a ratchetwheel 5 mounted on the spindle, the pawl 6 being operated by electromagnets 8 acting on an armature 7 connected to the pawl. A spring-held pawl 12 prevents backward rotation of the wheel 5, but can be withdrawn to release the wheel by electro-magnets 16 acting on an armature 15 connected to an arm 14 which can bear upon a pin 13 on the pawl 12. The electro-magnets 16 are energized either by a time-lag device or by contacts arranged preferably on the winding engine indicator dial to complete the circuit when the cage has reached a pre-determined point in the shaft, both means being included in the apparatus. The time-lag device consists of a cylinder 17 containing oil &c., the piston-rod 19 of which is connected to one arm 20 of a bell-crank, the other arm 21 being hinged to a rod 22 passing at its other end through an eye 23 on an extension 24 of the armature 7. The armature 7 in being attracted raises the piston in the cylinder 17, but on being released allows the piston to fall slowly owing to the eye 23 sliding on the rod 22, and to work a two-way switch. A lever 28 on the spindle 2 operates the two-way switch 29 when the pointer is at zero or at its higher limit.

Title: Improvement in the Feed Controls of Combined Surfacing, Boring, Milling and Drilling Machines.
IPC: B23B39/02
Filed: 1918-08-29
Abstract: 127,167. Kearns, J. R. C., and Kearns & Co., H. W. Aug. 29, 1918. Combined turning and boring or drilling machines; boring-bar machines.-In a machine for surfacing, boring, milling, and drilling, the radial feed of the facing-tool holder is effected through a vertical spindle from the main feed-box for the work table and sliding head, so that a large number of rates of feed may be obtained. The spindle a which is carried by the sliding head A is rotated by a pulley a<1> through belt gear and rotates by skew gear c<1>, c<2> the vertical spindle c of the feed-box C. This spindle carries two opposing bevel-wheels, either of which is put into gear by a clutch, according to the direction of motion desired. These bevel-wheels are geared to the bevelwheel d<3> on a shaft. d<4>, which is connected by gears e<3>, e<1 >or c', e<2> and a clutch f<1> to the shaft f to impart either a faster or slower rotation to the spindle f. Any of four sets of gears g, h may be put into action by a sliding pivoted feather i<1> on the spindle i, which is connected with the table and sliding head. The spindle i also carries a pinion j<1> engaging a wheel j<2> loosely mounted on the shaft f. This wheel gears with a spur-wheel on a shaft parallel thereto, which is also provided with a bevel-wheel engaging a bevel-wheel on a second vertical shaft l. This shaft drives, by skew-gear l<2>, l<3> and clutch m<1>, mounted in the sliding head, the shaft m , on which is mounted the spur-wheel n<1> geared through the wheel n<2> to a wheel n<3> connected with the track-wheel o of an epicyclic bevel-gear. The boring-spindle a, which carries the facing-chuck, normally rotates the feed-spindle u for the sliding facing-tool holder at its own speed by a spur-wheel p, which rotates the spur-wheel q carrying the free bevelwheels o', the wheels o<1> rotating the wheel o<2>, which carries a pinion s gearing with a spurwheel t on the spindle u. Any rotation given to the wheel o from the train of gearing previously described increases or retards the rotation of the spindle u as compared with the spindle a, and so effects the radial feed of the sliding facing-tool holder in its head in any manner, for example such as is described in Specifications 12122/12 and 19066/13. By the mechanism described, eight rates of speed in both directions may he imparted to the feed-spindle. The spindle m is provided with a hand-wheel v to effect the feed by hand.
