Title: Improvements in or relating to friction dampers
IPC: F16F7/09
Filed: 1962-04-25
Abstract: 945,917. Friction-vibration-dampers. HOUDAILLE INDUSTRIES Inc. April 25, 1962 [July 31, 1961], No. 15785/62. Heading F2S. In an hydraulically-operated friction damper wedge-shaped friction shoes 22, acting against a cylinder 20 and located between a wedge-ring 92 and a piston-ring 24 fixed to and slidably mounted on respectively a reduced portion 86 of an hydraulic cylinder 28, are urged radially outwardly by the hydraulic pressure built up in a chamber 74 as a load, imposed between rods 12, 14 connected respectively to the cylinders 28, 20, causes a hollow piston 30 with a head 54 to move into the pressure chamber 36 of the cylinder 28. Hydraulic fluid passes from the latter through an orifice 26 in the cylinder 28 and into the chamber 74 to actuate the shoes 22 and also through spaced orifices 32 in a metering tube 34 to a reservoir space between an end plate 48 for the cylinder 20 and a piston 38 which is fixed to the outer end of the piston 30 and has a ring seal 50, 52 which engages a liner 50 on the cylinder 20. A spring 40, located in a chamber 58 between a seating 102 on a cylinder cap 62 secured to the inner end of the cylinder 28 and the piston 38 also provides resistance to compression. The chamber 74 is defined by the space between the piston ring 24 and the cap 62 which is sealed against an axially-extending flange 80 on the ring 24 by " O " and back-up rings 76, 78. The piston 30 is maintained in sealing relationship with the external chamber 58 by means of a resilient annular seal 60 which is urged against the cap 62 and the piston 30 by a spring 68 which acts between a collar 70 on the inner end of the cylinder 28 and a bearing-ring 66. The pressure chamber 36 may be replenished through an orifice 42 closed by a filler plug 44. In a modification, Fig. 3, a piston-rod 120 with a head 164 is slidable within a cylinder 130, the highpressure chamber of which communicates with the space within a reservoir tube 106 through a series of spaced orifices 134 in the wall of the cylinder 130. The cylinder 130 has a pressure wall 131 which is slidable within the reservoir tube 106 and which, with a wedge ring secured to the inner end of the tube 106, defines a pressure chamber 132. When the piston head 164 moves into the cylinder 130 fluid under pressure passes from the high-pressure chamber 135 through an orifice 138 in the wall of the cylinder 130 and a transfer tube 140 to the chamber 132 to urge the cylinder wall 131 away from the wedge ring 133 so that a wedge-shaped piston 129 carried by the cylinder 130 is pressed into engagement with shoes 128 to increase their friction action against a barrel 118 having an end-plate 116 fixed to the piston-rod 120. The piston 129 is also urged against the shoes 128 by a spring 144 which is constrained between the end plate 116 and the back wall of the piston 129. A guide bearing 170, secured by a pin 172 around a reduced portion of the pistonrod 120 provides, with the piston head 164, a space 174 between the rod 120 and the cylinder.

Uniting bands 7 are pressed against a composite rod of alternate cigarette and mouthpiece portions C<1>,M, C<2> by a conveyer 1 and means are provided which, while the bands are still partially on the conveyer 1, tend to urge the side portions of the bands not in contact with the rod against the rod to prevent them curling downwards. A web 5 of cork tipping material is coated with adhesive at 5a and fed on to a suction drum 1 which moves at a greater speed than the web 5 and which has a suction compartment 3. Spring-loaded knives 6, operated by a hammer 18, cut the web at intervals to form uniting bands 7 which are moved away from the uncut web by the drum 3 and the central part of each band is pressed against the composite rod. Immediately thereafter the bands 7 pass beyond the suction compartment 3 of the drum 1 and compressed air from a compartment 8 in the drum is blown through the holes 2 to urge the sides of the band 7 upwards and prevent them curling downwards until they reach the conveyer band 23 of a folding mechanism which wraps the bands around the rod. The invention is also applicable to the application of uniting bands to separate assemblages each consisting of two cigarette portions with a double-length mouthpiece therebetween.
