Title: Improvements in or connected with kinematograph apparatus
IPC: G03B21/46
Filed: 1919-07-04
Abstract: 144,118. Barr & Stroud, and French, J. W. July 4, 1919. Kinematograph apparatus.-Film-centring with corresponding adjustment of shutter is obtained by several forms of mechanism. In the construction shown in Fig. 1, the driving-shaft A' has mounted on it a rotatable bracket D which carries the shutter-driving helical pinion C, the sprocketdrum driving pinion F, and the sprocket drum itself (not shown) connected to the pinion F through an intermittent-motion drive. Two universal joints G and an intermediate shaft G' allow the shutter E to remain vertical and also allow slight extension movement when the pinion C is adjusted and therefore moved farther away, or nearer to, the shutter in its rotation about the shaft A<1>. To centre the film, the carrier D is sufficiently rotated around the shaft A<1> by the hand-operated pinion B<1> and the rack D<1>, which gives a certain amount of additional rotation to the film-driving pinion F and a corresponding amount to the shutter-driving helical pinion C, thus ensuring synchronism during adjustment. In the construction shown in Fig. 2, the helical pinion is replaced by a bevel-gear. In the construction shown in Fig. 5, the helical pinion C' is mounted on the carrier D by end abutments P, P', which allow endlong movement of the pinion C<3> on rotation of the carrier, so that the axis of the pinion C<3> remains horizontal, and universal joints become unnecessary.

Title: Improvements in stop mechanism for yarn winding machines
IPC: B65H63/08
Filed: 1933-06-14
Abstract: 420,982. Stop-motions, tension arrangements and thread guides for yarn - winding machines. JARDINE, Ltd., J., 26, Deering Street, Nottingham, SWINDALL, J. W., 7, Haddon Road, and JONES, F. H. HASLAM-, 31, Violet Road, both in West Bridgford, Nottinghamshire. June 14, 1933, No. 16924. [Class 120 (ii)] Stop mechanism for yarn-winding machines comprises mechanical means which are adapted to raise a spool D from its driving drum E, Fig. 1 in combination with means which are adapted to connect the spool raising means to the longitudinally reciprocating thread guide bar J so that the said spool raising means are actuated by the latter when a spool is full or the yarn supply breaks or fails. A transverse stop slide A having an inclined cam part A<1> is mounted so as to be movable in a fixed guide way C. To the rear end of the slide A a stop lever G, G<1> is pivoted at A<2> the longer arm G being approximately horizontal while the shorter arm is approximately vertical and adapted to engage a catch B on one arm B of the spool cradle B<2>. As the spool is wound the cradle arms B rise and when the spool is completed the arm G<1> is released by the catch B<1> and the end of the arm G falls into the path of a cam incline H on the bar J, the lever G, G<1> together with the slide A being forced back thereby the cam part A<1> engaging the cradle arms B and lifting the spool D off the driving drum E. In a modification adapted to act on breakage or failure of the yarn a detector lever K, Figs. 2 and 3, is pivoted to the lower end of each thread guide J<1> and the lower end is extended to form a catch K<1>. The upper part bears on the yarn F against the action of a light spring. When the yarn fails the lever K is released and the catch K<1> falls and engages the free end of one arm M of a bell crank lever M, M<1> pivoted on a bracket L<1>, thus moving the lever M, M<1> and through a link O turning a second lever P pivoted to the bracket L<1>, the lever P lifting the cradle arms B, Fig. 2. In this case the slide A and lever G are inoperative. This modification can also be adapted to stop the machine when the spool is full by shaping the lever K so that when the yarn F has been raised to a certain point in the guide J<1> the catch K<1> will be lowered to engage the arm M. A pin G<2> on the lever G is adapted to engage a fixed catch V when the arm G is raised and the catch V is so formed that the pin G<2> moves clear thereof when the arm G falls. To maintain the tension constant and uniform each yarn passes over a cloth covered surface S and through two thread eyes R<1> between which the yarn passes under a roller T<1> carried on a lever T, Fig. 5, and is pressed downwardly thereby on to a pad. The Provisional Specification describes also a spring plunger device for re-setting the stop slide and cradle.
