摘要： 25,462. Colman, T. B. Nov. 15. Panels &c.-Panelled work for doors, partitions, &c. is constructed of a wooden skeleton framework B, C covered on both sides with fire-resisting material E and on one or both sides with wood veneer H, panels F of fire-resisting material covered. with wood veneer being secured in rabbets in the frame B, C so as to form air spaces D to lessen the transference of damp and heat through the structure. Instead of fitting the panels in rabbets, they may be secured in grooves, or to fillets mounted in grooves in the frame bars.

摘要： 10,589. Colman, T. B. May 4. Revolving doors.-Relates to revolving doors comprising either a number of manually or automatically collapsible radial wings, or a single central door with straight or curved end wings, and consists mainly in the provision of a revolving soffit. In the arrangement shown in Figs. 1, 5, and 8, the radial wings a hinged, preferably as described in Specification 22,552/10, to the central spindle, are connected by slip bolts or bullet catches k to a revolving soffit c, which is supported at the centre by an annular collar d bearing on a fixed collar e, and at its circumference by bearers g engaging a fixed ring h. The ring h may be carried by the soffit and the bearers by the casing i. The collars d, e and soffit c are slotted at m, n, l respectively to enable the door, when collapsed, to be pushed to one side on the usual trolly mechanism, the slot l being closed by a folding shutter. The disks b of the hinges are connected in pairs by rods q inserted and held by screws in slots in the wings a, the spaces between the central spindle and wings being occupied with filling-pieces v, carried by the spindle and grooved to engage beads w on the wings. In the application of a revolving soffit to the revolving door shown in Figs. 10 and 12, similar fittings g, h, d, e are used, but the slots m, in the collars d, e are omitted. The hinged end wings o, which may be straight or curved, are automatically collapsible and are provided with hinged portions P held in place by leaf springs or by bullet catches in the soffit, so that the wings may be forced out by excess of pressure from the inside. The central portion is provided with a folding swing door L, or with a pair of swing doors. The door is carried by a beam B secured to the revolving soffit c by bullet catches or slip bolts, and carried by a spindle C rotating on ball bearings and carrying a cam D bearing against a spring or weighted arm E for returning the door 'to its open position. The door revolves, at the bottom, on a pivot carried by the plate K, or on a spring- pressed pivot carried by the door L or on the floor, in which case the plate K is dispensed with.

摘要： 22,552. Colman, T. B. Sept. 29. [Cognate Application, 26,310/10.] Revolving doors.-Relates to revolving doors having three or more radial wings, which, after being folded together, can be moved bodily to one side of the door casing. In the arrangement shown in Figs. 1 and 3, each wing p is pivotally connected by pins f to lugs m on pairs of disks d rotatably mounted on ball bearings between collars b, c carried by a central spindle a, each pair of disks being connected by a rod h. The wings p are retained in the radial position by spring catches n, Fig. 3, which yield on excess of pressure in case of panic. In a modification, the wings are retained in the radial position by the engagement of spring catches on the wings with cross arms q carried by the upper end of the central spindle, one arm being hinged at r to turn back to allow the door, when folded, to be moved on one side. Spring catches may also be used between the wings and the central spindle, or the wings may be held in the radial position by yielding cables. In the modified form of crossarm shown in Fig. 9, the wooden arms x , reinforced with a metal core x , are secured in sockets x' of a casting y secured to the spindle a by screws z. The lower edges of the arms are lined with metal perforated for engagement by the spring catches on the wings. In the arrangement shown in Fig. 7, a door, consisting of wings p , p rigidly fixed to a spindle a and wings p , p hinged to the wings p , p , has its wings held in the radial position by hinged distance-pieces b, b , the free ends of which engage socket-plates d on the wings. To collapse the door, the distance-pieces b are released by means of screwed sleeves b , whereupon the distance-pieces b may be turned back, and the wings folded and pushed on one side. The door casing may be provided with the usual hinged sections.
