The adapter includes an apertured plate 24 between an existing apertured plate 23 in the flue, from which a damper plate has been removed, and the flange of a flanged duct 25 which is lowered into engagement with the combustion products outlet of the stove when fitted into position. An outer frame 2 of the stove supports a wire mesh or expanded metal screen 3. A flue damper plate 17 is linked by a crank 18 to a notched operating arm 8. The stove is closed by two pivotally mounted glass panelled or metal doors 5. Each door includes upper and lower pivot pins (26, Figs. 8, 9) removably mounted in apertures in a surrounding frame. In the case of metal doors, expanded metal may be used to cover the exposed surface of each door to define a space therebetween for convection airflow and to prevent contact with the heated door surfaces. Primary combustion airflow into the stove is controlled by two slidable doors (9, Fig. 1). A smoke deflector 25b to deflect downdraught 27 forms part of the duct 25. In another embodiment (Figs. 12-17), an existing flue damper plate (41) defines in a permanently open position a smoke deflector. The flue adapter includes a plate (48) having an opening, relatively slidable plates (51) to alter the location of the open area of said opening to match the location of the adapter duct (50), the assembly formed by the plates (48, 51) being held against a permanent damper frame (23) by extensible struts at opposite sides of the fireplace, each strut including two slotted T-bars. Some of the heated air flow in the space between stove and fireplace may be led through one or more ducts in the fireplace leading to a wall or floor outlet(s) which may be provided with a fan(s) for assisting airflow (Fig. 11). A boiler 70 may be placed in the stove combustion chamber and connected in parallel with the main hot water boiler 76 of a central heating system.

Title: Improvements in electric starters for internal combustion engines
IPC: H02K23/52
Filed: 1924-07-09
Abstract: 234,660. BarÚnyi, K. A. July 9, 1924 Dynamos, regulating; motors, controlling; commutators.-In an electric starter for internal-combustion engines comprising an armature having a high-resistance generator winding and having means for connecting either the generator winding or the motor winding to the commutator, for example, as described in Specification 208,396 the change of connection is effected by a number of pairs of elongated switch members adapted to be moved longitudinally relatively to each other. In the arrangement shown in Fig. 1, the shaft consists of two parts 4, 5 capable of slight relative angular movement. The commutator and armature are secured to the part 4, and the engine shaft is connected to the part 5. A tubular contact member 10 provided with insulated metal sleeves 12, 14 on opposite sides of a collar 11 projects outwards from each commutator segment. The ends 2 of the motor coils are brought through the segments 7 and tubular members 10 and are connected to the sleeves 12, while the generator coils 1 are connected to the sleeves 14. The commutator segments are connected through the collar 11 to the sleeve 12 or 14 by means of slidable sleeves 17. The contact sleeves 17 are secured to an internally-threaded ring 20 engaging with a sleeve 21 which is rotatably mounted on an extension 22 of the commutator. The sleeve 21 and shaft 5 are connected together through a ring 23 so that when the shaft sections are rotated relatively to each other (i.e. when the starting current is switched on), the sleeve 21 moves with respect to the commutator and effects a movement of the sleeves 17 into the position shown so that the low-resistance winding is in circuit. When the engine starts and overruns the motor, the switch is reversed so that the armature is connected up for generating. Fig. 6 shows a modification in which the contact-making members are disposed inside the commutator segments 26. The insulated sleeve 29 is connected at 32 to the low-resistance coils, and a central insulated rod 33 having an enlarged end at 35 to the high-resistance coils. By means of a slidable rod 30, the sleeve 29 or the rod 33 can be connected to the commutator segment. Fig. 8 shows a modification in which a tubular armature shaft 50 is rotatably mounted on a shaft 51 connected with the transmission gear. The screw-threaded sleeve 65 for effecting the required movement of the switch members is secured to the inner shaft 51, and between this sleeve and the armature shaft, there is a ring 69 provided on its opposite faces with segmental lugs 70, 71 the total circumferential length of which equals half the circumference. The sleeve 65 and shaft 50 are provided with appropriate lugs so that the two shafts can rotate through an angle of 360‹ or more relatively to each other. The shaft 51 may be connected at one end to a crank handle and at the other end to changespeed gearing of the type described in Specification 213,026.
