Title: Improvements in and relating to Variable Speed Driving Mechanism
Inventor: CORDNER ROBERT ALLEN
Filed: 1902-05-29
Granted: 1903-04-16
Abstract: 12,233. Cordner, R. A. May 29. Driving-mechanism; brakes; clutches. -Relates to epicyclic variable-speed gearing for cycles, motor cycles, motor cars, &c., the gear-changing mechanism of which is also applicable for other purposes, as in connection with brakes and clutches. Fig. 1 shows a three-speed gear, applied to the hub of a bicycle wheel, in which two trains of epicyclic gearing are employed. The planet pinions of one train and the internal wheel of the other are carried by the chain-wheel h, and the planet pinions of the second train and the internal wheel of the first are carried by the hub k. The central wheels of both trains are grooved internally to engage with short teeth on a sleeve a which fibs over the end of the inner part of the hub, or on a part connected thereto, and is formed with two internal cone surfaces adapted to engage respec- tively with a conical collar on the fixed axle band with a conical collar on a sleeve c screwed thereon. The sleeve a is movable endways ; when at the outer end of its stroke it is held stationary by contact with the sleeve c and its teeth lock the central wheel of the outer epicyclic train, which then comes into operation for the high gear. When at the inner end of its stroke, the sleeve is held stationary by contact with the collar on the axle, and its teeth lock the central wheel of the second train, which is then in gear for the low speed. When the sleeve is in the intermediate position, it is free from the axle and its teeth engage with the inner wheels of both epicyclic trains ; the hub is then locked directly to the chain-wheel. The chain ring may be mounted on a free-wheel clutch. The movement of the sleeve is effected by securing it to a ring d<2> free to rotate, but not to move endways, in a casing d, which is itself mounted on a screw-thread on the part c, whereby, when it is rotated in either direction by any suitable means, it is caused to move endways and to carry the sleeve with it. Fig. 8 shows a modified arrangement applied as a two-speed gear ; a single epicyclic train is employed, the pinions of which are mounted on the hub, the internal wheel being mounted on the chain-wheel, and the inner wheel formed on the sleeve itself. In this case the ball cup O<2> is made removable, being formed with segmental slots in its eye to fit over segmental wings on the end of the neck of the hub ; this construction allows the inner wheel to be made smaller in diameter. The conical enlargement of the sleeve may be locked against the ring N<2>, which runs with the hub or against the collar screwed on the axle. A modified arrangement of the three- speed gear with the same construction of ball cup is described and illustrated, also a two-speed gear with the ball cup, as in Fig. 1.

Granted: 1903-06-25
Abstract: 17,128. Lawrance, J. P. S., and Zell, T. B. Aug. 2. Anchors. - R e - lates to anchors the flukes of which are arranged to oscillate to a limited extent with respect to the shank. Fig. 1 shows a plan view, the hubs being in section, and Fig. 2 a sectional view along the line b-b of Fig. 1. The flukes 5<b> are carried by hubs 7, provided with the usual fins 8. Each fluke is cast separate, and is kept on the spindle 6<h> by the collar 18, which, however, permits free oscillatory movements. These movements are limited by the action of the rib 27 and the cavity 25, the rib being carried by the spindle 6<b>. The head of the shank has a larger diameter than the hubs, and is rounded off as shown. In order to have an anchor of this character, the flukes of which work together, the extensions and interlocking-fingers 30 and 31 are formed as shown in Fig. 3.

Granted: 1903-06-18
Abstract: 26,464. Page, S. E., [United Shirt and Collar Co.]. Dec. 1. Folding -instruments.-Relates to a machine for folding the edges of blanks for collars, cuffs, &c., and preparing them for stitching. Fig. 5 shows two blanks with their edges folded in and placed face to face ready for stitching. Two opposite edges of a blank are folded simultaneously, and then the remaining edges are folded in, so that the corners are not puckered. Of the two blanks placed face to face, one has the long edges folded first and the other has the short edges folded first, so that the thickened parts do not coincide. The blank is placed at the centre of the bed B of the machine, Figs. 4 and 9, just above the heating-chamber B<2>. An expansible templet, which is shown separately in Fig. 6, is then lowered on to the blank. The templet is held in a stock V, which is carried by a lever a<2> turning on a pin a<3>and balanced by a counterweight Y<2>. One pair of opposite infolders then advance, and fold over the ends of the blank. The templet is then contracted, and the pressers are lowered on to the infolders in order to press the folded edges. The templet is then again expanded, and the other pair of infolders J is advanced, and the edges again pressed. The stock V which carries the templet is formed with slide-ways v<1> v<2>, v<3> in which move slides d<1>, d<2>, d<3>. To the slides d<1>, d<2> are attached templet plates p<1>, p<2>, and heads G<1> are secured to the slides d<3>. Pins m<5>, m<6> on the slides d<1>, d<2> enter cam-slots in the heads G\ and the heads are connected by links L to a lever h<3> turning on a pin w<2> on the stock V, so that, by operating the lever h<3>, the templet can be expanded and contracted. The infolders are formed with shanks i<2> sliding between guidebars i<4>, which are clamped to the bed of the machine by bolts b<3> entering annular slots N. The slides i<2> are connected to plates p<6>, pins P on which enter cam-slots in plates 8, which are bolted to a ring R. The ring R lies in an annular slideway in the bed B, and can be turned, in order to move the infolders in and out, by means of a handle H. The plates S can be arranged so that the infolders move inwards simultaneously, or so that one pair of infolders move inwards when the ring is turned in one direction and the other when the ring ismoved in the opposite direction. In Fig. 9, the infolders are shown fitted with buttonhole-tab folders or nosepieces n<2> each of which is pivoted to one infolder and has a pin n<3> entering a slot n<6> in an adjacent infolder, so that, as one pair of infolders advance the nose-pieces are swung about their pivots. The pressers J are carried by bolts j<3>, Fig. 4, mounted on a table j<4>. Side-plates j<5> attached to the table j<4> are connected by a bar j<6>, which can be pressed downwards by a lever L<3> turning on a pivot on a projecting-bar t<4> carried by the bed B and operated by a link t<3> from a treadle.

Granted: 1904-06-09
Abstract: 10,571. Adams, T. E. May 7. Rock drills. - Relates to percussive drills driven by rotary electric or other motors. The slide 5, on which the drill casing 6 is fed, is attached to a bracket 4 carried by a clamp 3 on the bar or post, and anglebars 7, 8, with interposed shims, are fixed to the casing 6 to take over the edges of the slide 5. The motor casing is held by the trunnion ends 17 of a spring fork 15, which is secured by cottars in rings on either side of the bracket 4. The motor casing consists of a central ring 21 with two end shells 22, one riveted and the other screwed in place, and these shells carry ball bearings with dustexcluding washers for the armature shaft. A shaft 11 of angular cross-section extends through the armature shaft 10 and the hollow shaft 12, by which the crank shaft 39 of the drill is driven through bevel gearing. Washers 35, 45 are placed on the shafts 11, 12 near the bearings to throw off water and dirt by centrifugal action ; the washer 45 is formed with knobs, so that is can be used to turn the shaft by hand. The hollow shaft 12, with its bevel gearing, ball bearings, and dustexcluding washers, is enclosed in a box, which can be transferred from one side of the drill to the other, the bearing at the opposite end of the crank shaft being similarly transferable. The drill spindle 61 is reciprocated by a yoke 60 which is driven from the crank shaft 39 and lies between springs 65 on adjustable collars on the spindle. The springs may be of volute or other form, but preferably a series of helical springs of different lengths are used, as shown to increase the resistance at the ends of the stroke. Rotation of the drill is effected by straight and spiral grooves 68, 69 on the drill spindle, engaging respectively with two ratchet-wheels 67, which are prevented from rotating, each in one direction, by loose rollers 71, riding up the ratchet teeth and binding against the casing. An adjustable sleeve or bushing 75 is fixed in the casing in front of the ratchet gear, and carries a number of cushioning-springs 78. The tool is held by spring-pressed jaws 83 in the conical shank 89 which is screwed on the end of the spindle, a hardened steel abutment 81 being provided. A flexible dirt shield 16 is attached to the chuck 79 and to the drill casing. A sliding cap 99, held by a spring bolt, closes the other end of the drill casing. The feed-screw works through a pair of feed-nuts, one fixed and the other adjustable for wear, the latter being held by a spring catch on the casing engaging in notches on its edge. Undercutting &c.-To adapt the above-described drill for shearing or undercutting in coal mining, it is swung in a vertical or horizontal plane about the support by a worm 112 and segmental wormwheel 113, the latter being clamped on the post or arm, as shown in Fig. 13.

Title: Improvements in Apparatus for the Simultaneous Transmission of Telephonic and Telegraphic or other Currents over the same Line.
Inventor: TURCHI CARLO
Filed: 1904-06-04
Granted: 1904-08-25
Abstract: 12,691. Turchi, C. June 4. Telephone systems.-Telephone communication in a metallic circuit is carried on simultaneously with the transmission of another current along both linewires, by use of a differential inductance coil connected as shown, at each end of the circuit. The transmitted current may be another telephonic current, or may serve for telegraphy, or for simultaneous telephony and telegraphy ; or any alternating or continuous current may be transmitted. The differential inductance coil is wound on a bobbin having three compartments, the two end ones being short as compared with the middle one ; two wires cd, gh are wound together in the middle compartment, and are in series with two wires ab, ef, wound separately in the end compartments. In the middle compartment, the two wires alternate in position in each layer and in successive layers to keep down their relative electrostatic capacity. An iron core ST is adjustable longitudinally in the bobbin by a screw to vary the inductances of the windings ad, fg. The terminals A, D of the two line-wires are connected respectively to the terminals d, g of the windings. The terminals a, f of the windings are connected to the terminal M of the telegraphic or other apparatus P, the other terminal H of which is earthed. The resistances of the line wires being nearly equal, adjustment of the core ST enables the electric potentials of the terminals A, D, produced by the apparatus P, to be kept equal ; the current from the apparatus P divides through the windings ad, fg in opposite directions, so that the only impedance to it is that of the metallic resistance. The telephone apparatus T<1>, t is connected to the terminals A, D ; a very small part of the telephone current is wasted by passage through the windings da, fg, which act together to oppose such currents inductively. A telephone circuit provided at each end with a differential inductance, as shown, may be connected at M by a single wire to another like circuit, and so on, in a series. Telegraphic or other currents may be sent over the whole system thus formed ; communication may be had between any two telephones, additional wires being used in pairs to connect together the corresponding terminals A, D at the ends of each single wire intervening between the two telephones.
