Abstract: 3838. Haddan, R., [Moore, M. G.]. Feb. 15. Shirts; collars.-Applied to thecollar and cuff folding - machine described-- in Specification, No. 22,115, A.D. 1902, [Abridgment Class Sewing &c.] is a double templet comprising two series of plates h<1>, Fig. 13, mounted at right-angles to one another, and used to defineopposite - edges of the collar blank. The invention-consistsÀin imparting to the templet a cycle of movements, in which one series of plates is first depressed on to the collar while one edge is folded, then withdrawn and lifted, and the support rotated so that the second series can be similarly dealt with. The templet is automatically locked' to prevent unintended displacement, and to permit of all the movements, the blanksupporting bed is divided longitudinally, and one part together with the corresponding folder is removable. Each series of templet plates is mounted on blocks h, Fig. 1, fixed to two-armed brackets f, which' are adjustably secured at intervals on a. rotatable bar e. The bar e is of square cross-section between its supporting journals d, which are attached rigidly to an upper bar c forming the backbone of the templet. To obtain the movements of the templet to and from the work, the ends of the bar c are mounted in horizontal grooves in parts b depending from a cross-bar a<1>, which is reciprocated vertically by side bars a. To move the templet sideways so as to free it from the folded blank before the lifting movement, the bar c has a sliding engagement in the grooves of the parts b, and is moved transversely in them by a rod i, Fig. 4. One end of the rod is connected to the bar, and the other has antifriction rollers n engaged by a parallel motion mechanism m, Figs. 1 and 4, the function of which is to give the horizontal, without interfering with the vertical, motion. This horizontal motion of the templet as a whole is utilized to rotate the bar e with its brackets carrying the plates, so as to bring over the work the series of plates for defining the opposite edge of the blank. A pair of pawls l, Figs. 1 and 6, are pivoted on each of the parts b, 'the pawls oscillating in parallel planes, and being pulled by springs l<1> against fixed stops l<2>. Each of two pairs of fingers j, one pair on each end of the bar e, is arranged in the plane of one of the pawls, so that, at each transverse movement of the whole templet, one of the pawls will be pressed against its stop and rotate the bar e, and the 'other pawl will be moved idly round against its spring. The parts are so proportioned that this rotation is through a right-angle, leaving the next series of templet plates in readiness over the work. To prevent accidental lateral motion, the templet bar c is locked to the cross-head by causing bolts on the latter to slide into a notch in a plate on the bar. This is effected by a rod o, Fig. 9, made to reciprocate horizontally by a separate parallel mechanism p, Fig. 1, and having a cross-bar o<1> on it connected by links o<2> o<3>, o<4> with the bolts q. After rotation of the bar e to the desired position, accidental rotation is prevented by means of vertical gravity bolts s, Fig. 7, which drop into notches in a disk t, Figs. 1 and 7, on the bar, and are there held by forwardly extending projecting parts of the sliding bolts q. This arrangement causes the bolt q to leave its notch in the crosshead plate before releasing the bolt s. To allow the templet to make its transverse movements, the bed is divided longitudinally so that the front part v, Fig. 13, together with its infolder 13, can be dropped. A bar, passed at each end through vertically movable brackets, supports the section v, and the flat tops of the brackets support the infolder. The other half of the bed and its infolder are supported by another bar, which rests on fixed stops but may be raised by the pressure heads of the machine when the whole of the bed is raised to press a blank. Spring-pressed plungers project up from the bed under the infolders, and prevent shifting of the blank after the templet is removed.,
