No. 797,511 Claims priority, application Germany Mar. 7, 1958 8 Claims. ((31. 57-1) The invention relates to the constructional design of a spinning or doubling frame. In the normal recognised design of machine the headstock and the spring pieces of the machine are joined together in the top section by socalled roller beams on which the roller stands are mounted, usually being bolted thereto. Both the manufacture, and in particular the erection, of the standard design of spinning and doubling frames are expensive and lengthy processes. Upon final erection of the machine, after the roller beams have been fixed in place the roller stands carrying the rollers for delivering the yarn have to be mounted and very accurately aligned. Any adjustment to the height of these stands is thus a matter of very considerable difiiculty. Furthermore, the roller beams themselves present the grave disadvantage of having to be machined on all sides, this occasioning stresses in the original castings from which they are madethereby giving rise to subsequent deformation of the roller beams. It is quite possible for deformation resultant upon these stresses to reveal itself only months after. Because of this (and also as a result :of incorrect adjustment of the height of the roller stands) repeated breakages occur in the bearings of the delivery rollers.

One very big disadvantage of the spinning or doubling frame in the recognized construction as aforesaid, is the fact that these machines have to be completely assembled by the makers in their erection shops. In view of the size and great length of the machines, not only does this necessitate a very extensive time for the erection, which of itself increases the cost of the machine, but also means that large erection shops are essential to permit the complete assembly of these machines.

The fundamental idea of the present invention is to build spinning or doubling frames on the subasscmbly principle thereby ensuring that the spring pieces and the parts attached to them are all fully identical and that all mountings for the components extending the full length of the machine are arranged on these spring pieces. it is also claimed that, in consequence of the special design and disposition of the bearers on the spring pieces the manufacturing process, including not only the mounting of the bearers on the spring pieces but also and particularly the erection of the entire machine, will be very considerably simplified and speeded up.

Thus according to the present invention in a spinning or doubling frame the headstock of the machine and the spring pieces therefor, which constitute individual, single castings and which extend the full width of the machine, are firmly joined together only by long rods or some similar arrangement in the upper section, and in the bottom section by the spindle rails; at the same time all mounting parts for the components along the entire length of the machine are secured to the spring pieces, the latter being of identical construction, and this applies particularly to the roller stands (i.e. drafting roller stands), the driving shaft bearings, the vertical push rods for the up and down movement of the ring plate carriers, and the brackets for the creel.

This new machine frame construction considerably simplifies manufacture but most particularly simplifies the erection of such machines. In particular, it is no longer necessary for the machine to be assembled in its entirety on the manufacturers premises; instead it is SliillClGll't for 3,9?5,341 Patented Jan. 29, -163 the machines to be built up partially, in small sections. For example, the complete headstock and the spring pieces may be prefabricated as units. This means the saving of many hours of erection work and, furthermore, only a fraction of the space is required for the erection shops to permit of the assembly of such machines. The full extent of this very considerably simplified method of manufacture and erection is most notably attained if the supports, particularly for the roller stands, the driving shaft bearings, the brackets for the creel and also the carriers for the push rods on the face of the spring pieces are positioned in attachments parallel to the face of the spring pieces and are all fixed in precisely the same position at each spring piece by means of screws or bolts disposed longitudinally of the frame.

The invention will now be described further, by way of example only, with reference to the accompanying drawings, in which:

FIG. 1 is a part exploded diagrammatic representation of the assembly of a doubling frame;

FIG. 2 is a front view of a spring piece of this machine;

FIG. 3 a side view of the spring piece, partially sectioned to line III-Ill of FIG. 2;

FIG. 4 a plan view of the spring piece of FIG. 2;

FIG. 5 a view of a spring piece as in H6. 2 with all mountings fastened to and centered on this spring piece; FIG. 6 a vertical section on line VIVI of HG. 5;

FIG. 7 a part horizontal section through the spring piece of FIG. 5;

FIG. 8 a spring piece, represented diagrammatically, showing the setting arrangements;

FIG. 9 a section, to a larger scale, along line lX-IX of FIG. 5; and,

FIG. 1-0 a section to line XX of FIG. 5.

Referring now to the drawings, the headstock of the machine, carrying the gearing is marked 1. To couple this headstock to a support 2 standing at some considerable and varying distance from it, for example, four feet six inches, rods 3 or some such similar arrangement are provided, these serving to connect together the headstock and the supports 2 in the upper section of the machine. In the bottom section of the machine the headstock and the supports 2 are rigidly held together by the spindle rails 4 bolted therebctween, the parts being securely attached to the narrow sides 40 of the supports 2. The supports 2 are single castings in the form of a framework and extend across the full width of the machine.

As can be seen from FIG. 5 the supports 2 are all made identical, and carry supporting elements which are repeated along the whole length of the machine. Thus the following supporting elements are all bolted to the supports 2; the roller stands 5, driving shaft bearings 6, in which an integral elongated shaft member is mounted as shown in FIG. 6, and the winding drum bearings 7, in which an integral elongated shaft member 13' is mounted, as shown in FIG. 6, brackets 8 for the creel and also the vertical push rods 9 for the vertical movement of spinning device, such as the ring plate carriers. The carriers 10, bearing the ring plates 11, are (in the case of the double sided machine shown) rigidly fixed together by means of a stirrup 12 and are moved up and down in the normal manner from the lifting shaft 13 by means of a lifting chain 1.4;

The ring plate carriers 10 serve also as supports for carrying thread guides 15 and

antiballooning rings

16 and 17. To this end vertical rods 18 are fixed to the carriers In, the rods 18 having disposed thereon a bracket formation 19 and collars 2d, 21.

Parts

19, 20, 21 serve to carry

shafts

22, 23, 24, running longitudinally of the machine on which are mounted the thread guides 15 and the

anti-ballooning rings

16 and 17 respectively.

Shafts .22, 23, 24 are supported in a pivot bearing in parts 3.9, 2t 21. To allow the doiling of the spun or double bobbin, collars 2d, 21 can be moved upwards on the rods 1% by means of endless chains 25, till they come into contact with part 1'9, when thread guide 15, and

anti-ballooning rings

16 and 17 can be swung upwards until they assume a vertical position.

As can be seen from tle drawing, the roller stands 5, the driving shaft bearings 6 and 7, brackets 3 to the creel, and also carrier plates 26 are bolted to the faces of the supports 2 by means of bolts running parallel to the length of the machine. For the correct alignment of all elements of the frame, support portions 22 29, 3t 31 (FIG. 3) are provided on the supports 2, the surfaces of the supporting portions 2%, 29 and 3%, 3i lying in parallel planes parallel to the main plane of supports 2. Due to this construction, not only is manufactore considerably simplified {drill-holes and bolt holes extend all in the same direction) but also the erection of the frame. A further advantage of this arrangement for the fixing of the individual supporting elements to the supports lies in the fact that the mountings can be very easily set during assembly, and in any required direction, as indicated on 5. Qorrespondingly therefore the supporting

elements

3, 6, "1', d and 9 previously mentioned are firmly located in precisely the same position on each support 2 by the use of centering devices, for example jigs or gauges, whereupon they are then firmly locked in this position by the dowel pegs 27 and form supporting units With supports 2.

Preparation and assembly is effected as follows; the faces of supporting

portions

28, 29, 3d and 31 are first prepared and suitably machined so that the surfaces of all of them are absolutely parallel to each other and to an imaginary plane of symmetry of the support 2. The surfaces 40 (see FIG. 1) of the supports 2 are provided with bores 41, using drills and gauges to receive the spindle rails and the holes running longitudinally of the machine are bored in the supports 2 to serve for fixing supporting

elements

5, 6, 7, 8 and 9. Since all the holes are tapped the above mentioned supporting elements can then be located by means of a gauge, jig or other centering device and firmly fixed to the supports 2 in their precise final position by means of bolts (or screws) indicated by reference numerals 32 to 37. Then the holes for the dowels 27 are drilled and said supporting elements are firmly fixed in their final relative position by means of said dowels. In this manner, the supporting units are prefabricated.

The manner of positioning and fixing the push rods 9 can be seen from FIGS. 5, 9' and 10. A carrier plate 26 is in every case bolted to the lowest support portions 31 by means of a bolt 35 and fixed in place by dowel pins. The thickness of this carrier plate corresponds to the diameter of the push rod 9, the plate being made With a slot 49 bored in it in which push rod 9 is held both vertically and laterally. A bored slot 43 is in each case provided in the plate shaped stand to serve as a top bearing for push rod The push rod can be inserted in both slots 49 and d- The push rod is likewise held by the

holder plates

33 and 39, the latter being bolted to stand 5 and carrier plate 26 by means of

bolts

37 and 35 respectively. Dowels 27 can be provided to prevent the push rods 9 from turning.

The supporting units, prefabricated in the manner described and fitted with supporting elements 5 to 9, facilitate the assembly of the machine to an extraordinary degree. The supporting units are fastened together and to the headstock solely by means of rods 3 which are inserted in the holes 52 of the supports 2 and are bolted up accordingly. To allow of adjustment of the supporting units upon erection in the spinning or doubling room in the mill, setting screws are fitted to the supports 2, during manufacture of the latter, these setting screws being precisely adjusted as each supporting unit is assembled and are then looked in place by means of the two nuts 44.

The assembled supportin units are aligned in the mill by two setting gauges 4-3 laid on the setting screws 43 of two adjacent supports 2, see 8. These two gauges are fined beforehand to the spindle rail 4- at the same distance apart as the supporting units. By laying a spirit level on the spindle rail, the supporting units are then so adjusted as to be perfectly upright and perfectly level. The supports 2 are provided with feet adjustable as to height to assist in this worl: of levelling off, these feet including base plate 17 and adjustable bolts as locked in place by nuts When the supporting elements of all units are thus aligned, the elongated shaft members 13 can be easily mounted in the bearing parts of supporting elements 6, '7 and the same is true for elongated members mounted on supporting elements 5, and on other supporting elements of the units.

Although a particular embodiment of the invention has hereinbefore been described, in no way is the invention restricted to the precise details set out. Further embodiments will present themselves to one skilled in the art which may be used with advantage for other purposes.
