Abstract: 198,064. Carbone, T. L. Feb. 25, 1922. Arc lamps. - In a brake regulating-device, a double pawl is brought into engagement with the brake wheel by means of a radius arm pivoted on the axis of the brake wheel, a second arm pivoted on the outer end of the radius arm, and a connecting rod between the second arm and a solenoid core, this rod passing between the brakewheel axis and the common, pivot of the two arms. In one arrangement, the outer part of the radius arm g, Fig. 1, comprises two plates connected by two pivots h, o and a piece g, g. On the outer pivot h is mounted the second arm i carrying the double, pawl k, and on the inner pivot o is a lever p, the short arm of which bears against the back of the pawl, for additional security, except when the long arm of the lever p encounters a stop q. The solenoid core is connected to the pivot of the pawl k. In a modification, the lever p is replaced by a small lever which engages the base plata of the mechanism in order to free the pawl; also the second arm carrying the pawl extends back past the brake wheel and passes under a disengaging- stop. The small lever acting against the back of the pawl may be omitied, and the brake-wheel made smooth instead of serrated. In a further modification, the pawl is carried by the radius arm, and the second arm connected to the core has an abutment which bears against the back of the pawl except when an extension of this arm rises against a stop. In another construction, two links t<1>, x<1>, Fig. 8, are attached by a common pivot to a rod w<1> carrying the solenoid-core. One link t<1> is pivoted to the radius arm s<1>, and the other link x<1> is pivoted to a third link y<1> pivoted to the arm s<1>. The common pivot of the links x<1>, y<1> carries the double pawl z<1>. An extension of the link t<1> carries a roller v<2> which engages the base-plate to release the brake-wheel. The radius arm s<1> is adjustably clamped to an eccentric on the axle of the brake wheel. A counterweight o<1> is adjustably mounted on a lever m<1>, secured to a collar which can rotate on the axle of the brake wheel and carries a second arm slotted to take over the common. pivot of the links t<1>, x<1> and core-rod w<1>.

Title: Cold-molding process and product thereof
IPC: C08L61/06
Filed: 1924-03-04
Abstract: A composition containing a filler and a potentially-reactive phenol-aldehyde resin is mixed with sufficient of a high-boiling aldehyde capable of acting as a solvent for the resin, such as furfural, to yield a mass mouldable in the cold; articles are cold-moulded, and are baked at a temperature sufficient to transform the resin, but insufficient to vapourize a material proportion of the aldehyde.  The potentially-reactive resin may comprise a phenol-aldeyde condensation product in which the reaction has been stopped before the infusible stage is reached, or to which aldehyde hardening agents have been added.  Suitable high-boiling aldehydes are benzaldehyde, hexoic aldehyde, iso-hexyl aldehyde, manno-heptose, methyl-furfural.  According to an example, abrasive grains are mixed with a potentially-reactive phenol resin, preferably in powder form, a high boiling aldehyde, as furfural, is added and the tacky mass is moulded under heavy pressure, the article is removed from the mould, baked and allowed to cool slowly.

Filed: 1916-04-19
Abstract: 103,912. Platt Bros. & Co., Marsden, T. R., and Wilkinson, H. April 19, 1916. Guards, controlling. - A counter - balanced pivoted lap - guard for exhaust openers, Buckley openers, scutchers, &c., is locked at the commencement of the lap to prevent access to the lap and lap rollers, and as the lap is formed is gradually raised through the medium of the rock head until fully open. The guard a, which is fixed on a cross-shaft c pivoted in slots d, may be grid-like or of sheet metal and provided with a pivoted flexible flap a<1> and side pieces a<2>; it is counterbalanced by a weighted arm f, f<1> on the shaft c. Until the lap has been sufficiently formed to obviate danger, the guard is held locked by the engagement of a projection p on it with a pin q on the rack head h. As the rack head h rises, the pin becomes disengaged from the projection p, and an adjustable bowl j carried by the rack head lifts a lever k connected with the shaft c and gradually raises the guard as the lap is formed until it assumes a vertical position. Whilst being raised by the bowl j, the lever k is beneath an adjustable pin s on the rack head and therefore cannot be raised by hand. When the operator winds down the rack head, the pin s acting on the lever k restores the guard to the closed position shown in Fig. 1.

Title: Improvements relating to tail wheels and the like for aircraft
IPC: B64C25/50
Filed: 1934-01-31
Abstract: 431,042. Aircraft tail supports. DOWTY, G. H., 17, Lansdowne Crescent, Cheltenham, Gloucestershire. Jan. 31, 1934, Nos. 6233/35 (divided out of 421,223), and 5088/35. [Class 4] A tail wheel mounting for aircraft in which there is provision for castoring rotation incorporates an automatic device which effects self-aligning only in a substantially unloaded condition of the tail wheel which is rendered tree from the device when loaded. The tail wheel is secured to a member 1 pinned to a tube 2 which slides in a tube 3 secured to the aircraft. The tube 2 is formed with a cylindrical portion 6 having a diagonal face 7 co-operating with a similarly inclined face on a member 9 slidably mounted on a tube 5 fixed within the outer tube 3. The member 9 has a pin 10 which moves in slots 13 in the tube 5 and has a rod 11 which slides in a bush 12 rigidly fixed in the tube 5. When the tail wheel is loaded, the tube 2 moves inwardly so that the surfaces 7, 8 are separated and the tube 2 is freed for unimpeded rotation relative to the tube 3. When the load is removed, the surfaces 8, 9 are brought into engagement by the spring 15 and effect rotation of the tube 2 to the predetermined aligned position 1. The shock of recoil of the tube 2 when the load is removed is taken by a spring 14 on the rod 11. In a modification, the tube 2 is formed with a waist 20 normally opposite a friction lining 24 in a fitting 21 secured to the tube 3 and provided with a clip 23 and bolts 25 for circumferential adjustment. When the tube 2 moves inwardly its normal outer surface engages the friction lining so that the castoring rotation is damped. In a further modification, Fig. 3 (not shown), a lever pivotally connected to the tube 3 has one end which enters a circumferential slot in the tube 2 and the other end connected to a lever operating a cam which tightens a friction band surrounding the tube 2 when the latter moves inwardly. Specification 421,223 is referred to.
