Patent GB-189920390-A (GB)
Title: Improvements in Apparatus for Automatically Connecting any Two of a Number of Electric Circuits Branching from a Central Station.
Inventor: CEREBOTANI LUIGI
Filed: 1899-10-11
Granted: 1900-10-06
Abstract: 20,390. Cerebotani, L. Oct. 11. Distributing ; lighting systems of. - Relates to means for connecting any two electric circuits through a central station, applicable for telegraphy, telephony, lighting, controlling mechanical operations, &c. The apparatus depends upon the use of polarized magnets at the central station, and the sending of currents in opposite directions from the transmitter. Fig. 1 shows the central station apparatus for automatically connecting a station S with any one of a number of branch circuits. A switchboard F is fitted with a number of contacts connected to the branch circuits, and a contact C connected to the transmitter S is adapted to be moved over the board to make the desired connection. The contact C is connected to a grooved board P adapted to be moved horizontally by a toothed wheel h and vertically by a wheel h<1>. Two sets of polarized electromagnets B, B' and D, D<1> have their armatures arranged to operate ratchet or like mechanism for rotating the wheels h, h<1>. When " positive " impulses are sent by means of the key k<1>, the armature g<1> is rocked and the wheel h<1> turned, so raising the contact C. Then, on sending "negative" impulses by the key k, the armature g rocks, and the board and contact passes horizontally over the board to the desired contact. The receiving-instruments are adapted to respond to a positive current only, and hence this movement of the contact C does not affect them. When the desired contact is made, communication is made by positive currents from the transmitter S. The parts are restored to a position of rest by again sending negative impulses until the board is moved sufficiently to the left for the wheel h<1> to be over the deep groove t, when the springs E, e pull the board back. In a modified arrangement, instead of directly connecting up the circuits, a relay is operated in the branch circuit. Figs. 8 and 9 indicate the additional apparatus required when any two of a set of circuits are to be connected in such a way that the connection cannot be interfered with by another call. Each station, such as J and VI, has two wires, one for sending and the other for receiving. Each sending-wire 14 is connected to a contact C, Fig. 1, there being a switchboard F for each station. Each receiving- wire 15, 16 is divided into as many branches as there are stations, and the branches are connected through magnets 6, having permanently-magnetized cores, to the switchboards F. The circuits are normally made through the contacts 8, 9, but, when a circuit is completed at one of the switchboards, the current energizes the magnet 6 and its armature 13 is attracted. Each armature is connected to the arm 9 by a cord 19, and the general connection is thus broken. A communication circuit is at the same time completed through the connections 9, 20, 21, 22, and 8.

Title: Improvements in Bearings for High Speed Spindles and the like.
Inventor: RABBETH FRANCIS JAMES
Filed: 1899-11-24
Granted: 1900-02-03
Abstract: 23,480. Lake, H. H., [Rabbeth, F. J.]. Nov. 24. Emery wheels.-Relates to bearing for spindles of emery wheels &c., applicable to any high-speed bearings in which there is danger of vibration being set up owing to the centre of inertia not lying on the mechanical axis. A spring a, of corrugated or undulating form, is interposed between the bearing-sleeve b and casing c, the coils of minimum diameter clasping the sleeve and those of maximum diameter fitting tightly in the casing, while the intermediate coils form an elastic cushion. The ends of the spring may engage in slots in the sleeve and casing, if the friction alone is insufficient to prevent rotation of the sleeve. When the bearing is applied to a spinning-machine spindle, as shown in Fig. 4, the sleeve b<10> may be screwed on to the block e forming the footstep. If the tapered end of the spindle d<10> fits too tightly in the sleeve, the latter is rotated and is screwed downwards. The rotation of the sleeve is, however. resisted by the friction of the coils a' of the spring on the part b<12> of the sleeve, so that the downward movement of the sleeve is only continued to the extent necessary to relieve excessive friction.

Granted: 1902-11-06
Abstract: 23,922. Darby, J. H., and Stevens, A. J. Nov. 25. Moulding fuel &c.-A rammer or stamper H, for compressing fuel for a coke oven into a trough or box, or for other purposes, is raised by a driving- wheel J arranged opposite to a roller h mounted in sliding bearing-blocks I forced inwards by springs i, and is released by cams on a shaft j, driven by an engine Q, acting on the blocks I so as to force the roller h back against the springs. A toggle or eccentric friction grip M, or other catch, may prevent the fall of the stamper until the catch is raised out of action by a hand-lever m. Notches in the stamper come opposite to the wheel and roller when the stamper is in its highest position, and the stamper remains at rest until released by the hand-lever m. The machine is mounted on wheels R, and is moved backwards and forwards by pawls 0 which engage with a double rack or ratchet bar P, and are operated by a crank disc N and rocking lever n. A sliding sleeve o on the rack P can be moved by a handle to throw either of the pawls out of action, and stops may be provided at the ends of the rack to hold the sleeve and reverse the motion of the machine automatically. A bolt or catch of the sleeve handle holds the sleeve in any required position. Friction clutches may be used instead of the rack and pawl arrangement.

Patent GB-190215024-A (GB)
Title: Improvements in Regulating Devices for Ribbon Feeds.
Inventor: MARVIN HARRY NORTON
Filed: 1902-07-05
Granted: 1903-07-04
Abstract: 15,024. Marvin, H. N., and Casler, H. July 5. Feed-motions.-Relates to apparatus in which a strip, tape, or ribbon of metal &c. is fed forward in predetermined lengths, such, for example, as some forms of coin-controlled vending-machines; in which a strip or tape &c. is operated upon, or sold in, successive lengths, and applicable to various machines to control the feed for a given operation of the machine. The tape &c. 32 from a reel 91 passes round rollers 92 and between a slide 96 guided on a rod 94 and a serrated clamping-piece 97 pivoted to a bell crank 100. A rod 101 pivoted to the bell crank has an offset blade 103 which rests on a roller 104 on a slide 105. On inserting a coin into a shoot and pressing a slide 107, the slide 105 is moved to the right and the roller 104 presses the rod 101 to the right, extends the spring 102, and releases the clamp 97. The slide 96 is now free, and it falls till it rests on the stop 108. The rod 101 comes in contact with a pin 109, and its left end is disengaged from the roller 104, allowing the spring 102 to close the clamp 97. The tape is now free, and can be pulled or fed outwards till a predetermined length, namely, the distance between the stops 108, 110, has been delivered. In a modified form shown in Fig. 5, the slide 106, when pushed in after the insertion of a coin, acts through a bell crank 122 and link 123 to draw down the joint of a pair of toggle levers 115, 115<a>, and so draw a roller 111 away from a block 128, and allow it to rotate under the action of a spring until teeth 117 come in contact with a stop 119. Teeth on a block 120 prevent the tape from being fed forwards during this rotation of the roller 111. The springs 124 bring back the toggle to the position shown. The tape 32 can now be fed forward, and it rotates the roller 111 by friction until the teeth 117 come back to the position shown, and thus jam the tape against the block 128 and prevent further feed. When the roller 111 has nearly returned to the position shown, a pin 118 acts through a lever on a bell clapper 126 and sounds the bell 127.

Above the reflector is a grating g, and a top k is perforated so that hot air escapes into the atmosphere. The top may be made flat, to support articles to be heated. Switches may be used to vary the number of lamps and resistances in circuit.
Patent GB-190219474-A (GB)
Title: Improvements in the Manufacture of Earthenware Sanitary Pipes, Cable Conduits, Ridge Tiles, Roofing Tiles and other like Objects.
Inventor: STANLEY REGINALD
Filed: 1902-09-05
Granted: 1903-07-23
Abstract: 19,474. Stanley, R. Sept. 5. Moulding pipes, cables, conduits, ridge and roofing tiles, &c.-The invention is shown as applied to the manufacture of pipes without sockets. The clay is delivered into the space between a core 107 and a shell 108, and is subjected to end-pressure, in the same manner as is described in Specification No. 11,372, A.D. 1902, by two plungers 117, 112, of which the lower 112 is kept fixed during the compression. Means are provided for delivering the pipe downwards, for withdrawing the core, and for lubricating the shell. According to the Pro- visional Specification, it is also proposed to de- liver the pipe upwards. As the top plunger 117, hollow at the end to admit the core 107, descends into the shell, bolts 118, normally pro- jecting under the action of the spring 119, bear upon the shell 108 and force it down against the action of the spring 109. After the shell has moved down a short distance, wedge-bars 120. carried on the lower end of the shell, release the lower plunger by withdrawing from the slots 116 the locking-bolts 115 of the crosshead 113 bearing the lower plunger. At the same time the shell is allowed to return to its first position by the bolts 118 of the top plunger being forced in by plates 121, which are moved inwards by engaging with wedges 124. The plungers then descend with the pipe between them, the core being also carried down by the solid part 125 of the top plunger, until the pipe is free from the shell. The core is completely withdrawn during the ascent of the top plunger by means of wire ropes or chains 126 attached to the bottom of the core and passing under pulleys 127 and over pulleys 128 at the top. The crosshead 130, upon which the top plunger is mounted, carries expansible jaws 131 normally kept closed by springs 133, shown in Fig. 16, to lift catch-blocks 134 on the chains 126. The jaws are opened, to let the catch-blocks through during the descent of the top plunger, by wedges 135, and then close, lifting the catch-blocks as the top plunger ascends, and drawing the core below the top of the lower plunger, so that the pipe can be removed. The catch-blocks are then released by the wedges 136 opening the jaws on the ascend- ing crosshead. Counterpoises attached to the core by chains 138 passing over pulleys 139, Fig. 19, fixed to the bed-plate 141, raise the core to its highest position, a collar 143 on the core lifting the lower plunger to the locking position. The shell may be lubricated by pads 145 in the top plunger supplied with oil through chaanels 148, Fig. 17, fed with oil from a reservoir or from the upper part 146 of the plunger. The lower plunger may be similarly supplied. The other articles mentioned, such as multiple-way conduits, may be manufac- tured by using a suitable number of moulds and cores of the requisite shape.
