TEMPLE MOUNTING MEANS FOR LOOMS Filed April 28, 1964 INVENTOR.

RALPH H. BROWN JR.

A TTORNE Y United States Patent f 3,258,037 TEMPLE MOUNTING MEANS FQR LOOMS Ralph H. Brown, Jr., Ashland, Mass, assignor to Draper Corporation, Hopedale, Mass., a corporation of Maine Filed Apr. 28, 1964, Ser. No. 363,215 5 Claims. (Cl. 139298) This invention pertains to loom temples and, more specifically, to improvements in their support mountings on a loom.

It is a general object of the invention to provide an improved temple mounting means supported below the plane of the fabric in a loom, which includes a single continuous shaft having resilient torsional bushings constructed and arranged to permit at least one of the temples to be biased in a direction opposite to the motion of the fabric as it is formed.

It is a further object to provide an improved temple mounting means in which the temples may be adjusted laterally to accommodate the weaving of fabrics of different widths.

A further object is to provide a temple mounting means wherein means are provided on a common supporting shaft to permit one of the temples to be fixedly positioned relative to the other.

A still further object of the invention is to provide a temple mounting means which permits the temples supported thereby to be individually and independently biased in a direction opposite to the motion of the fabric as it is being formed.

Further objects and advantages of the invention will become apparent from the following more detailed disclosure.

Temples are normally utilized on practically all looms for weaving to maintain the fabric relatively taut at the sides thereof and in close proximity with the fell of the fabric or point of weaving, all of which is old and well known to those conversant .with the art.

The type of temples more commonly used are of the rotary type which utilize one or more rolls, the surface structure of which is adapted to grip or hold the fabric by its edges more or less securely. The types of rolls also vary considerably to accommodate different types of fabric and may be covered with rubber, cork, leather, or other materials and in many cases are provided with pins which actually project into and through the fabric.

As is well known in the art the interlacing of the filling threads with the warp threads creates sufiicient tension at beat-up whereby the fabric as formed has a natural tendency to contract and to become narrower than its reeded width. To maintain the fabric at its reeded width, the temples are set to reciprocate, that is, they are set beyond the front center of the lay so that at each beat-up of the latter the lay or abutments attached thereto are caused to strike What is termed the heel of a temple to move the same slighly toward the front of the loom. As the lay starts to move rearwardly, the temples assume their initial positions through the biasing force under which they are assembled. This means of temple setting causes the temple rolls to maintain their grip on the fabric very close to the fell line or point of weaving to prevent contraction of the fabric as it is formed.

In shu-ttleless looms such as those made by Draper Corporation, at Hopedale, Massachusetts, in which filling yarn is inserted in the form of loops or hairpins, the edge or selvage on one side of the fabric has what is known as a fringe selvage; or, in other words, this fringe is formed by the ends of the hairpins which protrudefrom the side of the fabric.

With this type of fabric, the tension referred to and described above is not created at that side of the fabric on which the fringe selvage is formed, and it has been 3,25%,h3'? Patented June 28, 1966 found desirable on many types of weaves to fixedly position the temple at this side of the loom so that it simply serves as a means for guiding this portion of the fabric. The opposite side of the fabric, however, is subject to this tension and requires a reciprocating temple to grip and hold the fabric outwardly to its reeded width.

The mechanism according to the instant invention provides a temple mounting means which is constructed and arranged so that the temple disposed on that side of the loom where .the fringe selvage is formed is fixedly positioned and the temple at the opposite side of the fabric is set and supported to move to and fro in a known manner.

This temple mounting utilizes a continuous shaft extending across the loom with the ends thereof being provided with torsion resistant bushings which are suitably supported intermediate the framework of the loom. The temple which is permitted to move has its supporting arm attached directly to .the shaft adjacent one end thereof and the torsional bushings provided on the ends of the shaft provide not only a suitable long-lived bearing upon which the shaft may be oscillated to and fro, but also the biasing force necessary for returning the temple to an initial position from which it is displaced upon successive beat-up movements of the lay.

A sleeve member encompasses the opposite end of the shaft and is fixedly positioned with respect to said shaft to permit the latter to oscillate on its bearings which are assemblled within the sleeve.

The temple supporting arm at that side of the loom is fixedly attached to the outer surface of the sleeve and maintains the temple carried by said arm in a relatively fixed position to guide that side of the fabric having the fringe selvage.

This form of temple mounting aside from permitting the temples to be independently controlled provides added rigidity to their mounting through use of the continuous shaft extending across the loom. This added rigidity corrects an unfavorable condition experienced in mountings of the prior art wherein a certain amount of flexing or winking of the temples is experienced due to the beat-up motion and the fabric tension created during weaving.

Should it be desired to have that temple move which guides the fringe edge of the fabric, a modification is provided and includes a torsional type bearing attached to the outer surface of the aforementioned sleeve. The sleeve being mounted in this manner is oscillated independent of the shaft and the temple arm attached thereto being under a certain amount of torsional strain biases the temple carried thereby toward the direction from which the fabric is being formed.

Looms of the type to which the instant invention is applicable are well known to those familiar with the art and for a more detailed disclosure of them, it is considered sufficient at this point merely to call attention to certain patents which are illustrative of the type of loom to which the present invention pertains. Reference is hereby made to the United States Patents Nos. 2,604,123 and 2,705,508.

The invention will be described hereinafter in greater detail by reference to the accompanying figures of drawing, in which:

FIG. 1 is a front elevation of a loom with the invention applied thereto;

FIG. 2 is an elevational view and partially in section taken from the front of the loom showing the temple mounting means according to the invention and the means by which it is attached to a loom; and

FIG. 3 is a view similar to that of FIG. 2 but showing only the mounting means for the left-hand temple and the modification which permits this temple to be rocked to and fro or oscillated with the sleeve upon which it is mounted.

Now referring to FIG. 1, part of a shuttleless loom is illustrated including loomsides 10 and 11,

longitudinal frame members

12 and 13, with member 13 being broken away for clairty to show the location and attachment points of the device according to the invention as applied to a loom.

At each side of the loom there is provided an

enclosure

15 and 16, respectively, within which is oscillated by a suitable known mechanism a tape wheel to which is attached a flexible, filling inserting member.

Harness frames 17 are suspended from a spring top

motion including brackets

18 and 19 and spring biased cords 20 running over a series of

sheaves

21 and 22.

The fabric woven is taken up in a roll 23 which is supported in a known manner by cloth roll stands 24 and 25, respectively. These cloth roll stands are disposed intermediate the loomsides 12 and 11 and attach at their lower ends to frame member 12 and at their upper ends to the underside of member 13.

The temple mounting device according to the invention and which is indicated generally by numeral 26 (FIGS. 1 and 2) extends between the cloth roll stands 24 and 25 and is supported by the latter by means of bearing

housing brackets

27 and 28, respectively, which are suitably attached thereto and adjacent the upper surfaces thereof. A continuous shaft 29 extends between and is supported by the

housing brackets

27 and 28. The ends of this shaft are machined to a lesser diameter than the portion intermediate said ends and are threaded as at 30 and 31 for fixedly retaining torsion resisting, resilient bushings generally indicated by numeral 32 thereon by means of hex nuts 33 and 34 (FIG. 2).

These bushings 32 include an outer sleeve 35, an inner sleeve 36, both of these preferably being formed from sheet metal and having between them a resilient rubber, or rubber-like annular bushing member 37 which is bonded to the adjacent surfaces of the sleeves.

As seen looking from the front of the loom, the outer sleeve 35 of the bushing assembled on the right-hand end of the shaft 29 is clamped in the housing bracket 28 and restrains said bushing against lateral and rotary movement. The inner sleeve 36 is compressed axially since it is caused to bear at one end against a shoulder on shaft 29 and is clamped by means of the hex nut 34 at its pposite end. The left hand end of shaft 29 is supported in a similar manner by the bearing housing bracket 27, but includes a sleeve member 38 which encompasses that end of said shaft and extends for a portion of the length thereof. The bushing 32 at this end of the shaft assembles in the same manner to said shaft as the one on the right-hand side. The outer sleeve 35 of this bushing rather than being clamped directly by the bearing housing bracket 27 is fixedly held by the inner surface of the sleeve member 38 and the outer surface of said sleeve member is fixedly positioned by the clamping pressure of said housing bracket 27.

A guide bushing 39 is disposed within the sleeve member 38 at its inner end and serves as an additional guiding surface for the shaft 29 which passes therethrough.

Bushings 32 assembled in the manner described provide a resilient mounting for shaft 29, and when the latter is caused to rotate slightly in an anti-clockwise or forward direction, it immediately returns to that position from which it 'was displaced when the forces that caused its movement are removed and which will be more fully described hereinafter. Sleeve member 38 being fixedly positioned permits shaft 29 to oscillate within said sleeve.

A temple supporting arm 40 having a temple 41 attached to the upper end thereof is secured to and adjacent the right-hand end of shaft 29 (FIGS. 1 and 2). Intermediate the position of the supporting arm 40 and that portion of the shaft supported by the housing bracket 28 a collar member 42 is provided having a means on the upper portion thereof adapted to cooperate with a laterally extending finger 43, which forms an integral part of 4 bearing housing 28, to limit the movement of shaft 29 in a clockwise direction. This means of limiting the movement of shaft 29 permits the bushings assembeld on the ends thereof to be pretensioned or preloaded thereby causing said shaft to be continually urged in a clockwise direction as seen looking from the right-hand side thereof.

The left-hand temple 44 is attached to the upper end of a temple supporting arm 45 the lower portion of which is secured to the outer surface of the sleeve member 38 adjacent the housing bracket 27.

This form of temple mounting has the benefit of added rigidity through utilization of a through-shaft construction and is constructed and arranged so that one of its temples is fixedly positioned with respect to other which is caused to be pivoted to and fro by the combination of the lay with which it makes contact at beat-up and the torsional stress applied thereto by the resilient bushings assembled on the ends of the shaft 29.

Should it be desired that both the rightand left-hand temples be allowed to contact the lay and to be rocked to and fro, a modification of the invention is provided as shown in FIG. 3.

This modification provides a shaft member 46 which is similar to shaft 29 but does not have the left-hand end thereof machined to a lesser diameter and threaded as said shaft 29.

A sleeve member 47 encompasses this end of the shaft and in place of the resilient bushing 32 said end is journaled in a guide bushing 48. Bushing 48 is fixedly positioned within the outer end of the sleeve 47, the outer surface of which serves as the inner sleeve or casing of a torsion type bushing generally indicated by numeral 49. This bushing includes an outer sleeve 50 and has a resilient rubber, or rubber-like, annular bushing member 51 bonded to the adjacent surfaces of the sleeves. The outer surface of the sleeve 50 is clamped and firmly held Within a bearing housing bracket 52 which is similar to bracket 27 but designed to accommodate a torsional bushing of larger diameter. This bushing 49 provides a resilient mounting for the sleeve member 47 and the temple supporting arm 45 and temple 44 when mounted thereon can be set in a similar manner to temple 41 and its supporting arm 44 so that it will also be caused to rock to and fro.

Like the means for limiting the movement of shaft 29, sleeve member 47 is provided with a collar member 53 having a means on the upper portion thereof which is adapted to cooperate with a laterally extending finger 54. This finger forms an integral part of bearing housing 52 to limit the movement of the sleeve 47 in an anti-clockwise direction as seen looking from the left-hand side thereof. This means of limiting the movement of the sleeve 47 permits the bushing 49 forming a part thereof to be pretensioned or preloaded thereby causing said sleeve to be continually urged in an anti-clockwise direction and independent of the shaft 46 journaled within and which extends therefrom.

In operation, the right-hand temple being set beyond the front center of the lay is caused to be rocked to and fro with its supporting arm that is attached to shaft 29. Contact with the lay moves the temple slightly toward the front of the loom and as said lay starts to swing rearwardly, the temple is returned to its initial position by the biasing force of bushings 32 upon shaft 29.

The left-hand temple and support therefor being fixedly positioned on sleeve member 38 simply serves to guide the left-hand edge of the fabric having the fringe selvage heretofore described.

With the modified version of the invention, both the rightand left-hand temples are permitted to move, but do so independently of each other. The right-hand end of shaft 46 (not shown) utilizes the same components as shaft 29 thereby permitting said shaft to oscillate within the sleeve member 47. The sleeve member 47 being a part of the torsional bushing 49 allows said sleeve to be oscillated independently of the shaft 46.

While one embodiment and a modification of the invention have been disclosed, it is to be understood that the inventive concept may be carried out in a number of ways. This invention is, therefore, not to be limited to the precise details described, but is intended to embrace all variations and modifications thereof falling within the spirit of the invention and the scope of the claims.
