Abstract: 303,987. Paulin, J. G. Dec. 6, 1927. Barometers.-Comprises a particular construction of barometer of the type in which the elasticity of a spring system or the like is used to balance the pressure exerted upon the vacuum box and in which the movements of the latter are indicated by a zero pointer connected to the member through a gearing device. The vacuum box 2 is connected to the under side of a frame member 1 and has attached to it by means of a nut 17 one shank of a. bent leaf spring 18 the upper shank of which is clamped in an interstice in a bar 20. This bar bears against two stop screws 21 and is provided with a projecting. arm 22 the end of which is connected by a screw 23 to a base plate. The leaf spring 18 is designed to relieve the vacuum box of the normal atmospheric pressure. The leaf spring is provided with two laterally projecting laps 24 to which are atttached the lower ends of two helical springs 26 the upper ends of which are secured to a yoke 25 rigidly connected with a nut 13 adapted to be adjusted by a micrometer screw 12 Journaled at the lower end in a fixed bearing 27. The nut is kept from rotation by a forked member 15 engaging a guide 16', the screw 12 being rotated to adjust the tension of the comparatively weak springs 26 which can be made of very hard material. The lower shank of the leaf spring 18 is provided with an angularly bent extension 18<1> forming a tongue 30 located between two stops 29 which limit the movement of the diaphragm box, and two projections 7<1> to which are attached vertical bands or strings 6, 6 connected by horizontal bands 5, 5 to arms on a floating spindle 3 the ends of which are supported on tensioned springs 32 the spindle carrying a pointer 8. In use, when a change of pressure occurs, the diaphragm box is restored to its initial position by operating the screw 12, a pointer 28 moving over a dial 9<1> and the pointer 8 being restored to zero.

A displaceable toilet seat cover comprises a disposable easily-torn sheet 12 with forward, rearward and lateral edges, having a generallycurved slit 15 separating a central flap 16 partially from the main body of the sheet 12 and a pair of tear slits 18, 9 extending transversely from a sheet edge defining between them a tongue 22 for accommodating means whereby a number of superposed sheets can be secured in pack form to a backing member 26, the rearward slit 19 being longer than the forward slit 18 and formed with a section adjacent its closed end generally convergent toward a projection of the line of the forward slit. Preferably, Fig. 1, the convergent section of the slit 19 is a curve of approximately constant radius with the adjacent end of the slit 18 as its approximate centre of curvature and the slits 18, 19 are rearward of a transverse line 17, approximately midway between the forward and rearward-edges, two pairs of slits being approximately opposite one another. Two pairs of slits 23, 24, approximately opposite one another, extend transversely of the flap 16 from the edges thereof, to accommodate tongues 25 for further securing the sheets 12 to the backing member 26, formed like the slits 18, 19 and also located rearward of the line 17, the slit 18 being nearer the line 17 than the slit 23. In a modification the slits 24 are a portion of the slit 15, extend in a direction roughly parallel to the slits 23, and converge at the closed end like the slits 19. In a pack identical sheets, Fig. 3, are folded along the line 17 with the backing member 26 on the outer side, having the superposed tongues secured to it adjacent to an edge with perforations 29. When the sheets 12 ere folded transversely away from the backing member 26, hung from the perforations 29, the forward and rearward portions depending in substantially vertical nested relationship from the tongues 22, 25, the forward edges of the sheets 12 project downwardly beyond the rearward edges. By downward pulling of a tab 13, to which recession 14 corresponds, it is torn through the tongues and removed. The sheets 12 may be mechanically-dispensed from a case.
