A window or door assembly comprises a fixed frame; a closure movably mounted in the frame; a rod 20; means mounting the rod along a member of the frame, the rod being rotatable about an axis along the said member of the frame, and the rod also being longitudinally movable along the said axis; an abutment 32 carried by the rod and rotatable into or out of the path of movement of the closure; means to prevent rotation of the abutment out of the path of movement of the closure when the rod is at one position along the said axis; and a handle 42 which is operable to move the rod longitudinally and to rotate the rod. As shown the handle has an open ended slot 50 in which the abutment 32 of the rod is disposed and the arrangement is such that the rod as well is being pivoted about its axis is also moved longitudinally to disengage a pair of flats 40 on the rod from a corresponding pair of flats of a nylon block 22 and which form the means which prevent the rotation of the abutment. The block 22 and a second bleak 24 mount the rod on the frame. The flats 40 are provided on a portion of the rod which is offset from the remainder of the rod. The rod also causes a second abutment 1-30 as shown. The rod and the abutments can be made of a single piece of material. The abutments are covered by a sleeve.

Title: Improvements relating to the manufacture of tin-plates and other like plates or sheets and machinery employed therein
IPC: B21B47/02
Filed: 1923-08-08
Abstract: 221,329. Thomas, H. S., and Davis, W. R. Aug. 8, 1923. Plates and sheets.- A machine for doubling metal sheets has combined therewith mechanism for mechanically transferring the doubled sheets to a shearing mechanism incorpor - ated in the machine. The doubled sheet is received between rollers 9. 10 which feed it past guides 11 to an inclined roller - way 12. The sheet passes thence between rolls 9, 15 which apply a final doubling pressure, to an endless chain conveyer 16 or to an inclined roller-way, from whence the sheet passes to a further roller-way 17, or chain conveyer, until arrested by the depending finger 18<a> of an adjustable transversely swinging stop 18. In a modification, a weighted lever may remain normally in the path of the advancing sheet, the lever being tripped by a stop on a chain conveyer 22. A flap 24 over which the sheet slides may be tilted, either by a. stop on one of the chain conveyers or by the motion of the lever in the modification referred to, in order to bring the doubled sheet into a horizontal plane so that chains 22, 23 provided with stops 22<a>, 23<a>, may convey the sheet in a transverse direction between the rotary cutters 27, 28 of a shearing- mechanism. During this transverse movement the free or folded edge of the sheet is held on a bridge member 30, by a weighted roller 31. The doubling may be performed by the machine described in Specification 181,844, [Class 83 (iv), Metals, Working].
