IPC: F23D11/00
Filed: 1918-01-23
Abstract: 120,489. Babcock & Wilcox, (Babcock & Wilcox Co.). Jan. 23, 1918. Liquid-fuel furnaces.-An oil-burning apparatus fitted to a furnace chamber consists of a burner 17, a mixing-chamber, and means for admitting air thereto, an air-deflecting plate 6 near the burner tip 18 and at the air end of the mixing chamber, and blades 4 secured to the inner wall of this chamber. Fig. 3 is a central longitudinal vertical section, the burner being shown in elevation, and Fig. 8 a vertical transverse section along a line parallel to and a little to the left of the plate 14 shown in Fig. 3. The mixing chamber comprises a cone-shaped casting 3 set in the furnace wall 1 with its narrower end directed towards the furnace. On the inner surface of the casting are the blades 4, which are substantially triangular in form witli two straight sides and a curved side conforming to the curvature of the inner surface of the casting; the blades are inclined to the front plate 2 of the furnace wall at an angle of about 60‹. The blades 4 are strengthened by a ring 5 cast with them, and the deflecting-plate 6 is also held against the ring 5. The plate 6 comprises two rings 6<2> and 8, between which are blades 6<1>, and is constructed in the manner described in Specification 27672/11; a flat deflecting-plate, like that described in Specification 18712/11 may be used. Some of the blades 4 have lugs engaging with the ring 8 and support the plate 6 in a central position. Fitted to the furnace plate 2 is a cylindrical box or casing 10 to the front flange 13 of which is bolted a cover plate 14 with a central aperture and hubs 15, 16 supporting the burner 17 of any suitable kind, such as, for example, that described in Specification 18711/11, [Class 75 (i), Burners &c.] On the hub 16 is adjustably mounted a collar 19 formed with an internal chamber to which oil is supplied by a pipe 20 and from which the oil is conducted to the burner by a goose-neck held in position together with the burner by a yoke 22. The casing 10 is formed with ribs 24 between which are air openings 25, which may be provided with doors 26 pivoted on pins 28 and normally kept fully open by the action of springs 30 surrounding the pins. Adjustment or complete closure of the doors 26 is effected by means of spider arms 33 extending from a rotary collar 32, on the hub 15, and a ring 34; this ring is connected to a handle 36 which traverses an are-shaped slot in the plate 14. When the ring 34 is rotated the arms 32 press upon angle-irons 31 on the doors 26 and force these outwards against the pressure of the springs 30. Bevelled or other suitable seats for the edges of the doors are formed on the sides of the ribs 24. The passage through the collar 15 is closed, when the burner is withdrawn therefrom, by a flap door 37, to prevent, inrush of air.

Title: Tool lifting mechanism for planing machines particularly high-speed planing machines
IPC: B23D13/00
Filed: 1952-01-18
Abstract: 695,263. Planing. KLOPP, F., [trading as KLOPP-WERKE GES.]. Jan. 18, 1952 [Feb. 13, 1951], No. 1453/52. Class 83 (iii). A planing machine comprises an angularlyadjustable head 41 on a ram 1, a screwed feed spindle 40, and a reciprocating member 55 on an operating shaft 36 and actuating a member 61 parallel to the spindle to lift the tool during the return motion of the ram. The ram 1 is mechanically or hydraulically reciprocated and carries an oscillating arm 5 bearing two rollers 8, 9 respectively engaging. adjustable stops 11, 12. The arm 5 is linked to a second arm 20 which, through a lost-motion system of sectors formed with slots and projections, transmits an adjustable degree of rotation to a, bevel wheel 35. This rotation is converted into a vertical feed-movement of the angularlyadjustable tool-holder 49 through bevel wheels 38, 39 and the screwed spindle 40 engaging a nut 43 fixed to the holder. Step-by-step feed of the tool is ensured by braking the shaft 36 carrying the wheels 38, 35 by an adjustable device 81, and braking the shaft 16 by a similar device, thus causing a pawl 32 to slip on each return movement. To cut out the feed, a lever 77 is operated to disengage the bevel wheel 38. Cutter-releasing.-Movement of the arm 20 also oscillates a member 57 to reciprocate the sleeve 55. The movement of the sleeve advances a pin 59 to rotate the square shaft 61 engaging a pin 70. The latter engagesan adjustable bolt 71 on the tool-box 53 pivoted at 52. A spring 64 returns the tool on the cutting-stroke. Stop mechanism.-If the nut 43 is fed too far in a downward direction it pushes the wheel 39 out of engagement and stops the feed. If it is fed too far upwardly it engages a collar 63 on the rod 61, thus allowing a lever 66 to pivot about its axis 67 and leave the wheel 39 unsupported.
