However, `the covering of the tubing ends in between operations on _the tubing should be such> as not to add ma terially tò the necessary labor in connection with the tubing and. notto add materially. to the eX'- y pense ofthe ultimate installationof the tubing. With the foregoing in mind, it is an important object of the instant invention to provide a meth od ofand means for very economically and sim k ply capping tubing in a temporary manner. Another object of the invention resides in the provision of a method of and means for quicklyy and easily capping tubing temporarily in a man ner and by means which, to a reasonable extent, will denote tampering with the capping material. Another object of the invention is the provision of capping means for the ends of tubing, Which » means are simple in construction, highly eco nomical to use, and which eifectively close the tubing ends, keeping out dirt, moisture, and other foreign matter, the means being as simple in removal as in application. A further object of the invention is the pro vision of capping means 'for the ends of tubing, which means are of such construction as to be y Figure13 isa fragmentary projectional view of a piece of tubing with which theinstant inven tion may be associated; and ` , „ , f Figure vIl is a'fragmentaryprojectional view similar to Figure 3, showing the tubing of Figure 3 cappedwith the structure of Figures 1 and v2. ` , As shown on the drawing: In the illustrated embodiment of this inven tion, with reference moreparticularly to Figures 1 and 2„'there is shown Ya device for temporarily capping a tubing, ypipe„conduit, Yorthe like. -‘The de'vice‘includes a fabric member 5 having an adhesive surface S, and the member in the illus trated instance is shaped generally in the form of a Maltese cross. This member may be made of any suitable material, but is preferably of a rather "substantial fabric of the character com monly used in the manufacture of the commonly known adhesive tape employed for surgical pur-V poses. Also, the member may be of the character of the so-called “Scotch” tape insofar as the adhesive surface is concerned. In any event, it is desirable that the member should‘have an ad hesive surface of the pressure sensitive type per mitting attachment and removal.

In Figure 3, merely by Way of illustrative ex ample, a conduit arrangement is shown which a sleeve 9 and a connection member such as a bushing l0 or the equivalent` is attached. The device of Figures l and 2 may be used to cap the structure of Figure 3 by placing the disk 1 in the opening at the end of the bushing I6, and then folding the arms of the cross-shaped device down over the nut portion of the bushing as clearly shown in Figure 4. It Will be noted that in this folding process certain overlapping portions at the side edges of the arms of the cross-shaped device will occur as indicated at ll so that there economical to use, no tools being necessary to manipulate the capping devices, and the devices themselves are sufficiently economical to Warrant discarding after a single usage. Further, the con struction of the capping device is such as to make it function to a considerable extent as a tell-tale in the event of unauthorized tampering with the tubing.Y It will, of course, be understood that various details of construction may be varied through a Wide range without departing from the prin will be a complete coverage of the end of the con-V ciples -of this invention and it is, therefore, not duit or tubing as far back as the skirt of the at«` thepurpcse to limit the patent granted hereon tached device extends.
