VACUUM APPARATUS FOR STRIPPING CARDING ENGINES.
Application filed October 21, 1827, Eaeriai 227,808, and in Great Britain fictober 26, 1926.
These improvements relate to vacuum apparatus for the stripping of the cylinders carding engines, of that type wherein a nozzle carrier, bearing exhaust nozzles for tl e vacuum stripping of the main cylinder and the adjacent dofl'er cylinder of the carding engine, traverses a double screw shaft and is tiltable to remove the nozzles from the cylinders. Such tilting has hitherto been effected by the displacement of a guide rod, the slackening of screws, or like positive operations. The objects of our improvements are to provide in apparatus of this type means for traversing the nozzle carrier whilst maintaining the same in correct relation to the cylinders being stripped; for tilting the carrier when desired without interfering in any way with the supporting or adjusting means, and for adj listing with exactness the position of the nozzles. The apparatus is thus improved and simplified in its parts.
With these objects inview our improvements comprise a rail on each side of the screwed shaft and parallel therewith, memhers on the nozzle carrier slidably engaging with these rails. A clamp which is pivoted to be swung out of the way when desired,
normally acts as a stop at one end of the screwed shaft when the nozzle carrier is in stripping operation. hen it is desired to tilt the nozzle carrier when stripping is suspended the clamp is merely swung over and the nozzle carrier can then be drawn further along so that the slidable member before referred to may leave the side rails or one of them, the tilting thus taking place automatically. The disposition of the parts is therefore such that when the nozzles are again to come into operation for stripping it is only necessary to move the carrier along and cause its sliding members again to make contact with the side rails, swing the pivoted clamp over to the position where it acts as a stop for the nozzle carrier, and stripping can again commence with the apparatus in exact position which it before occupied in relation to the card cylinders.
The improvements in a very convenient form as to mechanical details will now be fully described with reference to the accompanying drawings wherein Figure 1 is an elevation, viewed from the dofl'er cylinder side of the carding engine, of the improvements;
Figure 2 is a plan of Figure 1 and Figure 3 is an end view taken from the right of Figure 1, showing the arrangement of the pivoted clamp member and other details.
Referring to the drawings the nozzle carrier is provided with the nozzle at which is adapted to strip the main cylinder, and with the nozzle 5 for stripping the dotting cylinder. The doffer cylinder is indicated at A in Figure 3, and the main cylinder for the stripping of which nozzle 4 is provided is not shown. Nozzle member (5 has connected thereto a flexible tube which is in communication with an exhausting means, and a handle for a usual type of nozzle valve is shown at 7. The nozzle carrier is mounted on a central sleeve or boss 8 having a crutch of known type which engages in the thread of a double screwed shaft 9 through a longitudinal slot 10 formed in an outer sleeve 11. The latter surrounds the shaft 9 and not only serves for the smooth traverse of the nozzle carrier along the cylinder surfaces but prevents the filling up of the thread of shaft 9 with dust and fly.
The shaft 9 is rotated by means of a pulley 12 which itself is driven at the desired speed from any convenient part of the carding engine drive, and the said shaft is borne in the end brackets 13 and 1&- which are themselves screwed to further brackets 15 and 16 secured to the side cheeks l7" of the carding engine. To the brackets 15 and 16 are bolted two upstanding brackets 17 and 18 to which are secured by bolts 19 two rails 20 and 21 which are parallel to the shaft 9 but at different levels as seen clearly in Figure 3.
On the main cylinder nozzle 4 is cast a lug 22 tapped to receive an adjusting screw 23, and the doifer nozzle 5 is provided similarly with a lug 24 and adjusting screw 25. On the bearing bracket l4see Figure 3 and also right hand side of Figures 1 and 2is cast a lug 26 on which is pivotally mounted by the pivot pin 27 a semi-circular clamp 28 which normally, when the apparatus is in use is turned up to embrace and rest upon the upper surface of the sleeve 11. This clamp, in this position, serves therefore as a removable stop for the nozzle carrier at the end of its traverse.
When the stripping apparatus is in operation the nozzle carrier, engaged with the double screw shaft 9 through the slot 10, of sleeve 11 as stated, performs the reciprocating traverse of the shaft 9 in known manner, the clamp 28 being turned over upon the sleeve 11 to act as a stop but the nozzle carrier has at all points in its traverse a three point sup port, to wit, the sleeve 11, the rail 20, and the rail 21, the ends of the screws 23 and 25 acting as shoes which slide alon the said rails. A touch ensures that the nozzle carrier at the end of its traverse will engage the return screw of shaft 11. When it is desired to withdraw the nozzle carrier from its cylinder stripping position the clamp 28 is swung over to the position shown in dotted lines in Figure 3 and the said nozzle carrier is then free to be drawn further along the sleeve 11, until the screws 23 and 25 leave the ends of rails and 21. The side supports thus being removed the nozzle carrier can be swung around the sleeve 11 as a centre and it is then out of action until again required.
T he rails 20 and 21 are described and shown as being of the same length, but one of them may be shorter than the other so that when the clamp 28 is in the position of Figure 3 that screw 23 which acts as a shoe on the said shorter rail will fall as a result of the movement of the nozzle carrier.
Again, should it he thought at any time sutlicient to dispense with the sleeve 11, the nozzle carrier may ride upon the screwed shaft 9 and the clamp be adapted to embrace a reduced neck on the end of the shaft, the
function being exactly the same as above de scribed. Vie prefer the protective sleeve 11 for the reasons already stated.
The provision of adjustable screws 23 and 25 allows of a inicrometric adjustment of the nozzle carrier in'a very simple and convenient manner and the mounting of brackets 18 and letin their cradle brackets 15 and 16 ensures that when it is thought desirable or expedient to remove the shaft 9 and rails 20 and 21, these members will, when again placed in position,
resume the exact position they occupied before removal.
2. In vacuum stripping apparatus for card ing engines of the type referred to and having the features claimed in claim 1, members on the nozzle carrier which members slidably engage with side rails the said members being screws which are vertically adjustable.
3. In vacuum stripping apparatus for carding engines f the type referred to and having the featines claimcc in claim 1, a protective sleeve for the double screwed shaft on which sleeve the nozzle carrier may move, and a longitudinal slot in the said sleeve to allow engagement of the nozzle carrier with the threads of the double screw shaft which the sleeve encloses.
-l-. Vacuum stripping apparatus for card ing engines of the type referreijl to and having the features claimed in claim 1, and further characterized in that the double screw shaft and side rails are secured in end brackets which themselves are rcmovably screwed in cradle brackets substantially as hereinbefore setforth.
In testimony whereof we have hereunto set our hands,
ARTHUR Kill-ill. JOHN QAKD *N PO'lf'lllClt.
