Apr'il'ZB, 1957 I I E. DAUSCH TEXTILE DRAWING MECHNISMS 2 Sheets-Shea?l l Filed Dec. 7, 1955 United States Patent O TEXTILE DRAWING MECHANISMS Erwin Dausch, Esslingen, Neckar, Germany, assignor to SKF Kugellagerfabriken G. m. b. H., Schweinfurt, Germany Application December 7, 1955, Serial No. 551,696
Claims priority, application Germany December 8, 1954 14 Claims. (Cl. 19-135) The present invention relates to textile drawing mechanisms and more particularly to textile drawing mechanisms which include a set of top belts guided by a top belt cage and cooperating with `a set of top rolls of the drawing mechanism.
In textile drawing mechanisms `of this type the top belt cage is loosely connected to the top roll .loading means and has a certain amount of play which sometimes results in improper alignment of the top belt cage with respect to the remainder of the drawing mechanism. Such improper alignment results in undesirable operation of the drawing mechanism.
One of the objects of the present invention is to provide a top roll loading means and a top belt cage which cooperate with each other in a manner which guarantees proper alignment of the top belt cage.
Another object of the present invention is to guarantee this proper alignment of the top belt cage While at the same time providing the top belt cage with the necessary freedom of movement with respect to the top roll loading means.
A further object of the present invention is to provide an arrangement where proper alignment of the top belt cage is assured and at the same time a spring for urging the top belt cage downwardly toward the drawing belt is unnecessary. An ladditional object of the present invention is to provide an arrangement where the top belt cage cooperates with a saddle member of the top roll loading means in a manner enabling this -saddle member and cage to retain the shaft of the top rolls cooperating with the saddle member in its operating position while at the same time guaranteeing proper alignment of the top belt cage.
Also, the objects of the present invention include the 'provision of a structure capable of accomplishing the above objects `and at the same time being ruggedly and simply constructed and reliable in operation.
With the above objects in View the present invention mainly consists of a textile drawing mechanism which includes a top roll loading means provided with a saddle member. A top belt cage member cooperates with this saddle member, and a guide means is formed in part by the cage member and in part by the saddle member for guiding the cage member for turning movement with respect to the saddle member substantially about the axis of the top rolls which cooperate with the saddle member.
s The novel features which are considered as characteristic for the invention are set forth in particular in the appended claims. The invention itself, however, both as to its construction and its method of operation, together with additional objects and advantages thereof, will be best understood from the following description of specific embodiments when read in connection with the accompanying drawings, in which:
` Fig. l1 is a fragmentary partly sectional side elevational 'view' of a textile drawing mechanism including the struclture of the present invention, Fig. 1 being takenalong Patented Apr. 23, 1957 2 line 1-1 of Fig. 2 in the direction of the arrows and being turned through with respect to Fig. 2;
Fig. 2 is a view of the top rolls loading means and top belt cage of Fig. 1 as seen from the underside of Fig. 1;
Fig. 3 is a side elevational view of an arm of the top roll loading means which includes the saddle member of the present invention;
Fig. 4 is a sectional view taken along line 4--4 of Fig. 3 in the direction of the arrows;
Fig. 5 is a fragmentary perspective view of the saddle member according to the present invention;
Fig. 6 is a perspective view of the .top belt cage member according to the present invention;
Fig. 7 is a sectional elevational view taken along line 7 7 of Fig. 1 in the direction of the arrows;
Fig. 8 is a fragmentary view illustrating the top belt cage of Fig. 1 in a position where the top rolls cooperating with this cage are adapted to' be released;
Fig. 9 is a sectional elevational view corresponding to Fig. 7 of a diiferent embodiment of the present invention;
Fig. 10 isa sectional fragmentary side elevational view of la third embodiment of the present invention;
Fig. l1 is a fragmentary side elevational view of another embodiment of the present invention;
Fig. 12 shows the structure of Fig. 11 in a different position; and
Fig. 13 is a fragmentary sectional view taken along line 13--13 of Fig. l1 in the direction of the arrows.
Referring now to the drawings, and to Fig. 1-8 which illustrate one embodiment of the invention, it will be seen that a top roll loading means includes the elongated channel member 1 which is open at its bottom and which is adapted to be located in a known manner or is adapted to be retained in the operating position indicated in Fig. 1 with a releasable catch mechanism or the like. The channel member 1 is provided with a pivot pin 3 which exitends between its side walls, and an elongated member 2 is provided with downwardly extending lugs through which the pivot pin 3 extends, so that the member 2 is turnable upon the pivot pin 3, in the manner indicated in Figs. 1 and 2, the member 2 being located between the side walls of the channel member 1. The member 2 extends forwardly over the horizontally extending lower portion of a stop member 4 of substantially lv.shaped lcross section, as indicated in Fig. 1, so that when the member 1 is raised to an inoperative position, the downward movement of the member 2 will be limited by engagement with the stop 4.
The member 2 is provided with a pair of downwardly extending lugs 5 which carry a pivot pin 6 extending between these lugs 5, and an elongated arm 7 is pivlotally carried by this pivot pin 6 in the manner indicated in Figs. l and 2. The member 7 is provided intermediate its ends with a pair of downwardly extending walls forming from the member 7 saddle member 8a. Adjacent its forward end the arm 7 is provided with a saddle member 9 formed by downwardly extending wall portions integral with the arm 7. The saddle member 8a coopertateswith a set of top rolls 10 having their shaft engaged by the saddle member 8a in a well known manner, and a front set of top rolls 11 cooperates with theV saddle member 9. Springs 12 cooperate with the channel member 1 and the arm 7 for urging the ltop rolls 10 and 11 downwardly, in the manner indicate-d in Fig. l, when the channel member 1 is in the operating position indicated in Fig. l, these top rolls 10 and 11 are cooperating with bottom rolls, in the manner indicated in dot-dash lines in Fig. 1. v H
i The front wall of the channel member 1 `is provided with an inwardly extending bottom ange 13 over which the proections 15d of the saddle member 8d. As may be seen from Fig. 12, when the cage member is turned upwardly to a position where the projections 15d register with the cutouts into which they extend, then the shaft of the top rolls is surrounded by less than 180, and
in this position the top rolls can be easily removed. A
It will be understood that each of the elements described above, or two or more together, may also iind a useful application in other types of textile drawing mechanisms differing from the types described above.
' While the invention has been illustrated and described as embodied in textile drawing mechanisms having guides fora -top belt cage, it is not intended to be limited to the details shown, since various modifications and structunal changesl may be made without departing in any way from the spirit of the present invention.
Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can by applying current knowledge readily adapt it for various applications without omitting features that, from the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention and, therefore, such adaptations should and are' intended to be comprehended within the meaning and range of equivalence of the following claims.
