Title: Improvements in or relating to machines for making bottles or the like
IPC: C03B9/325
Filed: 1922-12-14
Abstract: 205,737. Wade, H., (Lockwood, L. V.). Dec. 14, 1922. Blowing. - In a bottlemaking machine of the type having a series of moulds carried by a rotatable carrier, threaded mandrels having gears free to slip on their axes are mounted in nuts carried with each mould, and racks are mounted on each side of the path of the gears, one rack being employed to raise the mandrels and the other to lower them. The racks are preferably yielding mounted to prevent jamming. As shown in the Figures, the invention is shown applied to a machine having invertible moulds. Each mould B<2> comprises a pair of main-mould sections 3 and a pair of ring-mould sections 3<a>, each pair meeting in a vertical plane and pivoted at 4 to a face-plate 1<a> mounted on trunnion 1, which in turn is carried by a bearing 2 on a table B. The sections 3 are connected by links 19 to a plunger 18 passing through the trunnion 1 and provided with a roller 18a which engages cams C, C' to open and close the moulds. A tubular member 5b carried by studs 3a from the face-plate 1<a> and interlocking with the ring-sections 3a, carries a nut 5, through which the threaded shank 7<c> of a mandrel E works. The upper end of the mandrel is provided with threaded tip 7<a> adapted to enter the ring-mould, and the lower end carries a gear E<1>, frictionally connected with the shank by means of the conical member 11<a> which is pressed by the spring 11<c> into the conical seat 11<b>. A rack F, yieldingly supported by bell-crank levers 12 on a standard 13 secured to the machine carriage, operates the gear E<1> to raise the mandrel E. A stop 8 on the shank 7<c> engages stops 9, 10 to limit the motion of the mandrel, the gear E<1> then slipping on its axis. Springs 15 operating between lugs 14 and the arms of the levers 12 allow of movement of the rack F. A similar rack F<1>, operating on the inside of the path of the gears E<1>, lowers the mandrels after the moulds leave the glass-charging station. This rack is also yieldingly mounted on a standard 17 by means of bell-crank levers 16 and springs 16<a>. At the bubble-blowing station the device G is pressed against the hollow stem of the lowered mandrel by means of the pneumatic plunger 25, air supplied by the pipe 21 passing into the mould by the passage 6<a>. On leaving the bubble-blowing station, the moulds are inverted by the gears 20 secured to the face-plates 1<a> engaging a rack D. The moulds are also opened and the blank transferred to a blowing machine. The moulds may be maintained in a vertical position during their travel by suitable locking means or by frictional contact between the trunnions 1 and bearings 2.

Title: Improvements in and relating to spindle mountings for silk twisting and like frames
IPC: D01H7/22
Filed: 1938-11-25
Abstract: 521,725. Spinning-spindle apparatus. SCRAGG & SONS, Ltd., E., and SCRAGG, T. W. Nov. 25, 1938, No. 34300. [Class 120 (ii)] In a machine where the spindles are held with their whorls against an endless driving band, the bolster of each spindle is slidably mounted in a slot 9 in the supporting member 7 attached to a part 8 of the frame. The spindle bolster 13 has a flanged top 14 with a projection 16 resting on a cam face 10 rising from the support 7. The bolster is held in its normal vertical operating position by a spring 17, but rotation by means of the handle 16 causes the projection 16 to ride up the cam surface 10 so that the bolster swings outwards in the slot 9 to bring the spindle and other parts to the position shown in Fig. 3 where the driving is discontinued and the top is given clearance for doffing. In the modification shown in Fig. 6 the supporting member is a ring with an. underplate 19 to receive the thrust of the spring 17. A pin 20 attached to the bolster projects through the plate 19. When the bolster is rotated by the handle 15 a projection 16 on the flanged top 14 rides up the cam surface 10 to throw the bolster and spindle to the position shown in Fig. 6. Brakes may be fitted to arrest the rotation of the spindles when they are pulled away from the driving belt, and the compression of the springs 17 may be regulated by adjustable nuts 17a.

Filed: 1970-07-16
Abstract: 1352834 Baling machines MASSEY-FERGUSON-PERKINS Ltd 2 July 1971 [16 July 1970 21 Oct 1970] 34433/70 and 50074/70 Heading B5F A hay pick-up drum or reel 5 of a baling machine 1 is driven by an endless belt or chain 14, the driving pulley or sprocket 12 of which is positioned at a higher level than its driven pulley or sprocket 11 so that when the reel is braked the increased tension occurring in the working lower run of the chain 14 raises the reel 5. The latter may be braked when its tines 10 encounter a minor ground obstruction 22 or when a reel brake band 40 is deliberately applied by the tractor driver pulling on a rope 60 to actuate a spring biased brake lever 38. When the reel 5 is raised the slack occurring in the return run of the chain 14 is taken up by a mechanism 13 comprising a snub idler sprocket 17 and a floating idler sprocket 19 mounted between a pair of spring biased pivotal arms 20. A suspension rod 30 constituting an adjustable height stop is connected between a pair of pivotal arms 8 rotatably carrying the reel 5. The rod 30 is connected to one of the arms 8 by a bolt (32, Fig. 4) which passes through a rod slot 33 so that, although resisted by a pair of spring loaded friction pads (34), it can move up and down as the reel 5 passes over ground obstructions. The rod 30 is also provided with notches 47 engageable by a pawl which is formed by one leg 48 (see also Fig. 5) of a spring biased U- shaped rod (49). The other leg (57) of the rod (49) carries a pulley (59) about which the rope 60 passes so that upon actuation of the brake band 40 the pawl is disengaged from a notch to allow the reel 5 and rod 30 to rise. An adjustable stop 60 limits upward movement. A shaft 3 taking power from the tractor drives baler knotter chains 15, 16 and the reel chain 14 via the sprocket 12. A porcelain guide 61 directs the rope 60 to the driver.

Title: Improvements in stop motions for gill spinning frames
IPC: D01H13/16
Filed: 1930-11-18
Abstract: 362,641. Electric stop motion for gill spinning frames. SCOTT, W. J., 78, Collins Street, Woonsocket, Rhode Island, U.S.A. Nov. 18, 1930, No. 34673. [Class 120 (ii).] In a gill spinning frame having sliver draft rolls and a spindle carrying a winding spool a stop mechanism, including a member adapted to be moved by abnormal sliver thickness, is mounted between the draft rolls and the spindle. Each sliver 21 passes through draft rolls 22, a comb 23, and a second set of draft rolls 24, 25, through the spacer frame 28 which carries the stop-motion control members and over a roller 29 to a spindle 10, guide eye 14, flyer arm 15, and bobbin 16. The bobbin rests on a drag washer 17 on the lifter plate 18 reciprocated by the mechanism 19, 20. The spindle is driven through pulleys 11, 13 and the belt 12. The spacer frame 28 comprises a bar 30 on which are mounted vertical slotted member 31, and a spacer member 36 the ends of which move in the slots in the member 31. The member 36 is held in a desired position relative to the bar 30 by bolts adjustably positioned in the slots 31. A contact pin 39 is connected to the spacer member 36 so that the occurrence of an abnormal sliver thickness rocks the member 36 and causes the contact pin 39 to engage a second contact pin 43, mounted on one of the members 31 but insulated therefrom, to complete an electric circuit. The completion of the circuit energizes an electromagnet which attracts to it an armature plate thereby freeing interengaging latch and catch members so that an operating lever normally held by the latch and catch members in inoperative position may move under the influence of a spring to shift a driving belt from a fast to a loose pulley.
