Title: Multiple friction clutch
IPC: F16D21/06
Filed: 1935-07-29
Abstract: 457,023. Friction clutches ; changespeed gearing. SCHOU, C. E. J., 69, Kalfarvei, Bergen, Norway. July 29, 1935, No. 19565/36. Divided out of an application under which a Specification was laid open to inspection under Sect. 91 of the Acts, Jan. 29, 1936. [Class 80 (ii)] A multiple clutch suitable for change-speed gearing comprises nested friction clutches which are engaged by spring means common to them all. Thus, spring means 6, Fig. 1, engages all three plate clutches which have driven discs 7, 8, 9 fast respectively upon nested shafts 10, 11, 12. There is a common driving plate 2 which carries a casing 2b forming the abutment of the springs 6. When disengaging levers 60 are free, the springs 6 engage the three clutches simultaneously. As a flange sleeve 23 is moved left of Fig. 1, the clutches are disengaged in the order 7, 8, 9. The sleeve 23 turns the levers 60 clockwise of Fig. 3. At the first step, the levers 60 engage nuts 65 and pull rods 62 and a plate 3 right far enough to free the driven disc 7. The plate 3 like other plates 4, 5 slides on bolts 2d carried by the plate 2. The discs 8, 9 are still both driven and held engaged by the springs 6. At the second step, the rods 62 are still carried right, but rods 63 farther from pivots 61 of the levers 60 are engaged and carried a greater distance right so that the plates 3, 4 separate and free the disc 8, leaving the disc 9 alone driven. Further rocking of the levers 60 about their pivots 61 causes rods 64 still farther out to be engaged and pulled right at a still greater rate so that the plates 5, 4 are separated to free the last clutch 9.

Title: Improvements in and relating to the delivery of bobbins from winding machines
IPC: B65H67/04
Filed: 1953-07-15
Abstract: 735,492. Winding and packaging bobbins. SCHARER, K. J., [trading as MASCHINENFABRIK SCHARER]. July 15, 1953 [July 21, 1952], No. 19633/53. Class 94 (1). [Also in Group IX] Apparatus for winding and packaging bobbins comprises an intermittently-rotating turret 1 carrying three winding spindles 3 each formed with a base 3a for the reception of a bobbin B, the turret being indexed to position each spindle in turn at a winding station where it is coupled to a drive spindle (not shown) and then at a discharge station where the wound bobbin is removed by an ejector 5 which is reciprocated along a guide 4 in synchronism with the movements of the turret. The ejector deposits the bobbin in an arcuate cradle 6 pivoted at one edge to a rod 7 which is mounted on a slide-member 14 reciprocable on a vertical guide 13. The cradle rests at its other edge on an abutment carried by a transverse plate 8 secured to the rod and carries a depending feeler 9 arranged to engage the bottom or bobbin content of a removable open-sided magazine 37 so as to cause tilting of the cradle when the slide-member has been lowered by the required amount. The movements of the latter are determined by the engagement therewith of a pin 35 on an endless chain 26 passing over an upper sprocket mounted on a fixed spindle and a lower sprocket integral with a pinion 30 mounted on a spindle carried by a spring-loaded lever 23 pivoted at 24. A second lever 16, 19, pivoted at 17, is coupled at one end to the ejector 5 by a chain 20 and spring 21 and carries a roller 22 at its other end arranged to engage in notches 23a and 23b of the lever 23. As the ejector moves to the right, the lever 16, 19 is operated to move the roller 22 out of the notch 23a and into the notch 23b whereby the lever 23 is swung about its pivot to cause the pinion 30 to mesh with a drive pinion 32. The chain is thus driven to cause the slide member to move downwards until the feeler 9 causes the cradle to tilt so that the bobbin rolls off into the magazine. The slide member is then raised to its original position to position the cradle for the reception of the next bobbin, and at the end of this movement a roller 15 thereon engages the lever 16 and swings it to the left, thereby returning the roller 22 to the notch 23a so that the lever 23 is returned to its original position by its spring to disengage the pinions 30, 32. Several turrets and associated mechanism may be arranged side-byside so that bobbins are fed simultaneously into a similar number of magazines supported on a common platform 36, see Figs. 6 and 6a (not shown).
