CHECK STRAP FOR LOOMS Filed Feb. 9, 1949 JNVENTOR. HENRY M. BACON Y C EC STRAP FQR. LOOMS.
Wash., assignor to The Dayton a corporation of Ohio Henry M. Bacon, Lacey,
Rubber Company,
Application February 9, 1949, Serial No. 75,387 4 Claims. (Cl. 139-161) The present invention relates to check straps for looms and more particularly to checkv strapsv for fly shuttle looms which are designed to, check rearward motion of the picker stick caused. by impact of the shuttle, as well as forward motion, of the picker stick, after it hasv thrown the. shuttle. in its return through the loom.
Straps of thistype have previously been made of leather either in the form of a strap having the ends bolted together and to the loom frame to form a loop, or in the form of an endless band which surrounds the stick and is supported: by friction fingers which restrain movement of the strap under the impact of the picker stick. In order to obtain uniform action of the shuttle it is important that the performance of the check strap should also be uniform. Since the strap is subjected to repeated impacts of the rapidly moving picker stick it must have sutficient strength, flexibility and resilience to provide. the necessary restraining action upon the stick without excessive wear and without excessive frictional drag. Furthermore, the strap must not be sensitive. to changes in temperature, of humidity as is generally the case with leather.
The object of the present invention is to provide a check strap which will not, be subjected, to the aboye, disadvantages and which will have long life, flexibility, the correct frictional resistance and. resiliency, and which shall not be sensitive to. changes. in temperature and humidity.
In accordance with my invention, a, check strap having an endless annular form is. provided having a novel construction and which will have. a long life. while avoiding the objections to. the use of leather. This endless type of check strap is particularly adapted for mounting in association with friction fingers in a manner such that each blow of the stick causes the strap to. move an increment progressively moved in a horizontal so that the strap is between the friction fingers. In this step by step manner manner each impact is strap. In such a strap it, is important to have a maximum of strength, flexibility and impact resistance, and also to provide a uniform rate of movementunder impact These results are obtained by forming a continuous strap composed, of successive layers of fabric, rubber and cord, in which the outer surface layers of the strap are formed of one or more layers. of fabric and one or more intermediate layers of longitudinally arranged reinforcing members, such as layers of parallel cords, the cord layers being separated from the outer fabric layers by cushioning layers of rubber.
taken by a different point on the The accompanying drawings illustrate the various forms of my invention in greater detail.
Referring to the drawings:
Fig. 1 illustrates the endless annular check strap of the present, invention in perspective.
Fig. 2 is a cross sectional view of one form of the invention taken along line 2'-2' of Fig. 1.
Fig. 3 is a cross sectional view of another form of the invention taken along line 2-2 of Fig. 1.
The strap shown at 10 in Fig. 1 is illustrated in a tensed and elongated position. In practice, the strap is disposed with the loop in a horizontal plane with the picker stick positioned within the loop. The strap is supported between friction fingers and is moved in a step by step manner between the fingers as the stick strikes the inner wall.
Two forms of strap construction are illustrated in Figs. 2 and 3. It is generally preferable to make these straps by first forming a cylindrical sleeve of the desired dimensions made up of the various layers of materials, and
2,698,032 Patented Dec. 28, 1954 drel is then wrapped with one, or more layers of fabric.
as shown. at 15 in Fig. 1 and 22 in Fig. 3. This fabric may be rubberized, or impregnated with rubber, either natural or synthetic, and may, if desired, have a skin surface coating of rubber. The fabric may be square woven, and either bias laid or straight laid, depending:
upon the specific ultimate properties desired. If desired, bias and straight laid fabric layers may be alternated; One or more layers of fabric may be applied tothe drum. The term bias laid means that the fabric is cut at an angle to the direction of the threads or cords thereof and is applied to the drum=with thethreads at an acutev angle to the longitudinal axis of the drum.
Over the fabric layer or layers is superimposed a cushion layer of rubber shown at 14 in Fig. 2 and 21 in Fig. 3. Upon the cushion layer is then wound a layer of cords shown at 13 in Fig. 2 and 20 in Fig. 3. These cords may be of cotton, rayon or. nylon and preferably have been, preliminarily treated or impregnated to improve their adhesive properties for rubber. This treatment may be by impregnation with rubber latex or rubber solutions, or with a resorcinol formaldehyde latexcomposition as used in the treatment of tire cord. The
manner, and the windings may be contiguous or spaced as desired. The cord may be woven together and placed around the drum as a cord fabric and may be applied embedded in rubber.
Another cushioning layer of rubber is then applied over the cord layer as shown at 12 in Fig. 2 and 19 in Fig. 3. In the form shown in Fig. 2 one or more fabriclayers 11 are then wound around cushion layer 12. These are. preferably rubberized as in the case of Figure 15 and may be of the same or different construction. The number of layers same as or more or less than those on the inner layer. In the modification shown in Fig. 3 an additional layer of cords 18 is applied followed by another cushioning rubber layer 17 prior to application of fabric layer or layers 16. For certain applications it may be desirable to provide more than two cord. layers, each layer being separated from the other by a cushioning layer of rubber.
The assembly of the laminated layers described above is now ready for vulcanization. Preparatory to this it is rag wrapped to place the respective layers under pressure in order to obtain a unitary structure after vulcanization. This is accomplished by tightly winding strips of heavy fabric known as rag wrap material around the assembly.. The wrapped drum is then placed in an autoclave where it is vulcanized in the presence of steam in a conventional manner. The various rubber materials have, of course, been compounded with vulcanizing agents, acceleratory agents, pigments, fillers and the like as is well known in the art.
After vulcanization the assembly is taken from the autoclave and the wrapping removed. The cylindrical composite sleeve while on the mandrel is then cut into a plurality of bands or straps of the desired width, being severed circumferentially by means of knives spaced at the desired distance and the resulting check straps removed from the mandrel. As shown in Figures 2 and 3, the side edges of the respective layers are exposed by the severing operation.
It maybe noted that in the drawings in Fig. 2, for example, layers 12, 13 and 14 are shown as separate and distinct. This is for the purpose of illustration only since during the vulcanization process the whole is fused into one integral unit with the fabric layers becoming bonded to each other and to the adjacent rubber layers, while the rubber layers become integral with the cords embedded therebetween. The cords are shown as embedded in a rubber layer, but where the cord is wound directly on the cushion layer and then the other cushion layer is applied thereover, the cords may be considered to be embedded between these two layers. The resultant product of Fig. 2 will, therefore, consist of fabric layers, a cushion layer, a row of cords, another cushion layer above the cords, and
of fabric on the outer layer may be the other fabric layers, with the cord embedded between the cushion layers which are integrally united.
Check straps for looms corresponding to the structure shown in Fig. 2 were formed as follows:
plies rubberized square woven 8 02. cotton fabric, bias laid 1 ply cushion layer of neoprene 1 ply rayon cord .053 gauge 1 ply cushion layer of neoprene 6 plies rubberized square woven 8 oz. cotton fabric, has
laid
The above layers were assembled on a drum in the order given and wrapped, vulcanized and cut in the manner described above to form a number of check straps 9 inches long, /2 inch wide and A inch thick.
Other check straps conforming to Flg. 3 of the drawing were formed as follows:
4 plies 8 oz. enameling duck square woven, bias laid, to .025 gauge per ply, skim layer ofgum on each side 1 ply .012 gauge butadiene acrylic nitrile copolymer rubber (Hycar) 1 ply cotton cord .022 gauge 1 ply Hycar .012 gauge 1 ply cotton cord .022 gauge 2 plies 8 oz. enameling duck as above The above layers were assembled on a drum, as described above, and vulcanized, then cut to form straps 1% inches wide, 7 inch thick and 26 inches long.
In preparing the cushioning layers descrlbed herein, or in rubberizing the fabric or cords, either natural or synthetic rubbers as well known to the art may be used. The term rubber as used herein is intended to and does include the natural rubbers as well as the synthetic rubberlike and vulcanizable elastic materials known as synthetic rubbers including the rubberlike conjugated butadiene hydrocarbon polymers and copolymers with styrene, acrylonitrile and other monomers copolymerizable therewith containing an active CHz=C group, the halogenated d1- olefin polymers of the chloroprene type known as neoprene, the polysulfide rubbers of the throkol type, and the isobutylene-diolefin copolymers of the butyl rubber type.
For some purposes it may be desirable to subst tute a fabric layer for the cord layer and it has been poss1ble to fabricate check straps of this type consisting of a plurallty of layers of fabric each separated from the other by cushioning layers of rubber. In general it is preferred to have rubberized fabric on the outer surfaces of the strap due to their high resistance to friction and abrasion. In some cases, however, it may be desirable to have the surface layers of rubber superimposed upon the outer fabric layers. The fabric may thus be consideredas embedded 1n rubber. The cords referred to herein are generally composed of natural or synthetic textile fibers, usually cotton, rayon, or nylon. Instead of being spun orwoven, the cords may in the case of synthetic material be of the extruded type. In some cases it may be desirable to utilize as cords, Woven or cabled wires of steel or other metal.
While the foregoing structure has been described in connection with acontinuous annular member, it may also be utilized in the fabrication of check straps of other types, for example, where a strap is used WhlCh is fastened at both ends to the loom.
The foregoing disclosure sets forth the principles of the invention and any other modifications thereof WhlCh may come within the scope of the invention are intended to be covered by the appended claims.
