Patented May 11, 1954 2,677,858 F I CE CRADLE FOR TOP APRONS AS USED IN HIGH-DRAFT SYSTEMS Howard E. Kuehn and Ross B. Newton, Whitinsville, Mass,

assignors to Whitin Machine Works, Whitinsville, Mass, a corporation of Massachusetts Application April 8, 1953, Serial No. 347,508 2 Claims. (01. 19-131) This invention relates to high-draft systems by slip roll previously described.

It is the general object of our invention to provide an improved cradle or apron support to be used in the second construction. This cradle is designed so that it may be easily applied or conveniently removed, when and as desired.

More specifically, we provide a cradle having slight inherent resilience and so constructed that it will firmly grip a fixed guide-bar associated with the bottom apron.

Our invention further relates to arrangements and combinations of parts which will be hereinafter described and more particularly pointed out in the appended claims.

A preferred form of the invention is shown in the drawings, in which:

Fig. 1 is a sectional end elevation of parts of a drawing frame embodying our invention;

Fig. 2 is a perspective cradle in attached position;

Fig. 3 is a detail view of a guide-bar;

Fig. 4 is a diagrammatic view indicating how our improved cradle is attached to the permanent or fixed guide-bar;

Fig. 5 is a front modification; and

elevation showin a, detail Fig. 6 is a sectional side elevation, taken along the line 6-6 in Fig. 5.

Referring to Fig. 2, our improved cradle comprises side plates I c and II, spaced apart and held in fixed relation by a cross bar I2 which also acts as a guide-bar for the top apron. The ends I 4 of the bar I2 are reduced in size to provide shoulders and are inserted and secured in slots I 5 in the side plates m and I I.

The drafting assembly with which our improved radle is to be used is shown in Fig. 1, in which a relatively long bottom apron is driven by the middle bottom roll 2i and passes around a fixed guide-bar 22 and a yieldingly-mounted weighted tension roll 24.

The usual front rolls and SI and the usual back rolls 32 and 33 are also provided, and a previously described.

The side plates i c and I I are made of some material,

lower edge of the guide-bar. The inherent remit easy removal when desired.

The upwardly extendin arms 53 of the side plates are convenient in applying pressur when attaching the cradles to the bar 22, and they also provide additional side surface for guiding the edges of the top apron 46. construction is shown in Figs. 5 and 6 may also be narrower in their upper portions as shown at to increase It will be particularly noted that no tools are required for attaching or removing these cradles, and that the cradles and top aprons may be placed in operative position without stopping the rolls 2|, 36 and 32. The

versa as desired.

Having thus described our invention and the advantages thereof,

the bottom apron, said cradle comprising spaced and a connecting cross bar which acts as a guide-bar for the top apron, said side plates being inherently resilient and having spaced gripping portions which are yieldable for firmly seating said cradle on said fixed guide-bar.

2. A cradle for the top apron of a double apron high-draft system having a fixed guide-bar for the bottom apron, said cradle comprising spaced side plates and a connecting guide-bar, said side plates each having a shoulder to engage one edge of said fixed guide-bar and having an integral hooked arm to engage the other edge of References Cited in the file of this patent UNITED STATES PATENTS
