    Provisional Specification. A.D. 1868.—N° 885. 3 TV. 8f TV. Arthur’s Improved Trass. the requisite curve for attachment to either side. When this curved lever is used the plate may he convex in one or both directions, and less in length by about one-fourth, such reduction of length to be from its upper end. In umbilical hernia the plate is of an oblong shape 5 from above downwards, and is retained in its position over the hernia by two cross bars fixed across the plate at either end; two straps are required, one round the hips, the other round the waist, for attachment to the upper and lower levers or cross bars. The straps are made of strap leather, with the smooth or cuticular side to the wearer’s skin, 10 and beveled off to nothing on the other side. The transverse section of the strap would be represented by Fig. 4. We call our Invention the )(-shaped balanced or crucial truss, con¬ sisting of a plate which covers the hernia, together with arms extending at either side for the attachment of a strap which passes round the pelvis 15 and above the hips, called the pelvic strap. # We claim a plate of any shape with arms or levers fixed or sliding extending from any part of it, which shall cause it to be balanced over the hernia by the application of a pelvic strap. We claim any plate or pad which shall have the pelvic strap attached 20 to its centre, that is to say, one half above, the other half below the strap attachment, and which shall thereby be balanced over the hernia. We claim the application of a curved bar or lever with rotary action, for fixing with increased power in certain cases the lower end of the plate, together also with its mode of attachment to the pelvic strap at 25 the opposite side of the body. We claim the application of sliding levers with elastics or springs attached posteriorly for the purpose of compensation. We claim the application of elastics or springs to the anterior ends of the levers for the purpose of compensation. 30 We claim straps beveled off to nothing on the rough side, and with the cuticular side applied to the skin for the purpose of sustaining the plate. The plate (see Fig. 5) will in many cases require a larger superficies above than below the cross bar, because of having more firm support for the lower portion.
