Daley, Clifton, N.J., assignor to Specialties Development Corporation, Belleville, N.J., a corporation of New Jersey Filed Feb. 11, 1960, Ser. No. 8,112 4 Claims. (Cl. 242-2 The present invention relates to the manufacture of articles composed of resin impregnated yarn such as fiberglass, and, more particularly, to a cup-shaped article of such manufacture which is adapted to be used as the end wall of a receptacle and to a machine and a. method for producing the article.
The present invention is primarily concerned with the manufacture of receptacles composed of resin impregnated yarn having a generally cylindrical side wall and at least one generally hemispherical end wall. It has been proposed to produce such receptacles by the combination of longitudinal end-over-end windings and hoopwindings. In such a receptacle, both types of windings provide side wall structure and the end-over-end winding provides end wall structure. However, unless an excessive number of layers of end-over-end windings are employed, which would greatly increase the Weight of the receptacle and would defeat the high strength for weight ratio advantage of such receptacle over metallic receptacles, the end wall does not have sufficient strength. Thus, in order to reinforce the end wall, metallic end fittings have been resorted to even though such fittings imposed a weight penalty.
Accordingly, an object of the present invention is to provide a cup-shaped article composed of resin impregnated fiberglass yarn or the like which is suitable for use particularly as an end wall reinforcing member for receptacles of the type mentioned hereinbefore.
Another object is to provide such an article in a simple, practical and economical manner.
Other andfurther objects of the invention will be obvious upon an understanding of the illustrative embodiment about to be described, or will be indicated in the appended claims, and various advantages not referred to herein will occur to one skilled in the art upon employment of the invention in practice.
In the drawings:
FIG. 1 is a schematic view of apparatus for making the cup-shaped articles illustrated in its condition at the start of the winding operation.
FIG. 2 is a view similar to FIG. 1 illustrating the article partially formed.
FIG. 3 is a view similar to FIG. 2 illustrating the article at the completion of the winding operation.
FIG. 4 is a fragmentary view partly in longitudinal section and partly in elevation illustrating the article embodied in a receptacle as an end wall reinforcing member thereof.
Referring to FIG. 1 of the drawing in detail, apparatus is shown which generally comprises a member having a convex surface 11, a second member 12 having a concave surface 14, a post 15 at the center of the surfaces, and means for causing hoop windings to be formed about the post.
The members 16 and 12 are connected together by the post 15 in spaced apart relation to provide a space 16 between the surfaces 11 and 14 which defines the wall thickness of the article to be formed. The post 15 may be removably secured to both of the members 10 and 12, but preferably the post is integral with or is permanently secured to one of the members and the other of the members is removably connected to the post by suitable means. For example, the post may be in securement with the member 10 and may be threaded at its upper end, the member 12 may have a central aperture 17 through which the post extends, and a nut 18 may be threaded over the upper end of the post.
In order to space the surfaces 11 and 14 apart a predetermined distance, a collar 13 may he slipped over the post 15 and seated on the member 10 before the member 12 is mounted as shown so that, when the nut 18' is secured, the member 12 is drawn against the collar to position the same and the collar is thus clamped between the members 11} and 12 to prevent rotation thereof. In this manner the collar serves as a post during the winding operation. When the cup-shaped article is to be used as an end wall member for a receptacle, the collar may have a flange 19 to provide a flanged spud which becomes part of the article and serves as an inlet and/or an outlet opening for the receptacle.
The means for causing hoop windings to be formed may constitute a shaft 20 connected to the member 111 and driven by a motor 21 for rotating the members 11) land 12, and a stationary eye 22 for guiding yarn to the lower end of the space i16 so that the yarn is wrapped about the post 15 and onto the collar '13. Alternatively, the members '10 and 12 could be stationary and the eye 2,2 could be on a flyer (not shown) which revolves about the members .10 and 12 to lay the yarn in the space 16. In both cases, the yarn is taken from a supply 2 4 and passed through an impregnator for applying the resin thereto.
In operation, with the members 1d and 12 secured as shown in FIG. 1, the leading end of the resin impregnated yarn is tied to the collar 13 and the drive 211 is started. This causes layers of hoop windings to be formed about the spud which build up in diameter (FIG. 2) and continue to build up land fill the space 16 and produce the. wall of a cup-shaped article 26 having the collar 13 and the flange 119 embedded therein (FIG. 3).
Thereafter, the nut 18 is unscrewed and the member 12 is removed to enable the article to be removed from the member 10. The article 26 which is composed of resin impregnated yarn, may be cured or partly cured in any desired manner. Preferably, a parting agent is applied to the members '10 and 12 which prevents the article rrorn adhering to these members.
As shown in FIG. 4, the article 2 6 with the spud embedded therein provides end wall structure for a receptacle 27 comprising layers of end-over-end windings 23 which hold the end wall in place and form side wall structure and hoop windings 2 applied over the windings 2 8 which form additional side wall structure. The windings 28 and 2a are formed of resin impregnated yarn similar to that used to produce the windings of which the article as is composed.
From the foregoing description, it will be seen that the present invention provides a simple, practical and economical manner of producing cup-shaped articles from resin impregnated yarn which is strong but yet light in weight.
-As various changes may be made in the form, construction and arrangement of the parts herein, without departing from the spirit and scope of the invention and without sacrificing any of its advantages, it is to be understood that all matter herein is to be interpreted as illustrative and not in any limiting sense.
