Abstract

Improvements in the principal patent 232,843, by "an adjustable mechanism to regulate the inclination and clamping of devices for drawing", characterized in that the substantially horizontal and parallel axes mounted, with the faculty of axial displacement, in the support frame of the board assembly, are of tubular constitution, closed ends and have practiced, in their two end parts, two pairs of coaxial holes each other, of which only a pair of each axis are acolisados and corresponding the two pairs of the front axle with other two separate pairs of circular holes that includes the horizontal tubular element of the aforementioned support frame, which houses the aforementioned axis while the pairs of orifices of the rear horizontal axis correspond to other pairs of holes, acollised, which have, in an annular direction, two mounted sockets coaxially and loosely on such rear axle and collaterally emplaced with the ends of the horizontal tubular element of said support frame that locates such an axis and is, consequently, of shorter length than the homologous and parallel front element, all in such a way that the sliding supports are substantially vertical, and cylindrical articulated, superiorly, to the board, besides passing through the respective pairs of holes of the corresponding axes, the front ones are inserted with the respective pairs of holes of the previous tubular element of the support frame, and the rear ones with the holes of the respective casings; with the particularity that by one of its ends, precisely the one that comprises the pair of acollised orifices, those repeated axes are authorized to receive the screwing of individual rods, operable at will, operatively arranged to press on the corresponding sliding rods all of so that, when these mentioned pressure rods are screwed, they are applied with force against the surface of the corresponding sliding paths, front and rear, immobilizing them in the position immediately prior to the tightening of the pressure rods, in coadjuvation with the corresponding pairs of holes of the front tubular element of the frame and of the support and of the rear sleeve, respectively, previous displacement and support take on the rear tubular element of the support frame, of the latter, at the same time that they establish, respectively, the sensitive displacement the axial axis of the horizontal axes in the sense of reducing the dimensions of the coinciding portions of the pairs of circular holes of such axes and of the front tubular of the support frame and the posterior bushing, respectively, after displacement and support bearing on the tubular element. Rear 40 of the frame 12, of this last bushing and, therefore, blocking the other sliding rods, front and rear, simultaneously with the other two, likewise, anterior and posterior.
