Dec. 23, 1958 H. WALSH- DIELECTRIC TELESCOPING BUCKET Filed Aug. 14, 1956 INVENTOR. /1/ EL f /V Mu 5H BY ATTQFJVEY United States Patent Office 2,865,421 retreated Dec. 23, 1958 My invention relates generally to buckets, and speciiical ly to buckets used for transporting tools and equipment which buckets are formed of non-conducting material, and are capable of being telescoped into a small;r size for convenience in storage.
It is among the objects of my invention to provide a.
bucket which is safe to use to transport tools andy ma terials in the vicinity of high-tension electric lines.
It is a further object of my invention to provide a. bucket which may be collapsed for the purpose Ofcom-- serving storage space when the bucket is not in. use.
Yet a further object of my invention is to provide: a capacious bucket for the transportation of tools and equipment.
Among the further objects of my invention is to pro-- vide a bucket which is durable, compact, lightweight,A strong and relatively inexpensive.
These objects and advantages, as well as other objects. and advantages may be achieved by the device illustrated in the drawings in which:
Figure l is a partially-sectioned, side-elevational view of a dielectric telescoping bucket illustrative of my invention;
Figure 2 is a partially-sectioned, side-elevationalf view of such a bucket distended;
Figure 3 is a partial, vertical-sectional view thereof; and
Figure 4 is a perspective view of the bottom of the bucket disassociated from the other parts.
Referring now to the drawings in detail, a bucket made in accordance with my invention is provided with an annular top frame. This frame is composed of nonconducting material, such as tibreboard. This frame 11 has a top enlargement 12 which defines the upper limit of the overlap of a web with the frame. It is preferred that the frame be annular, although it may be square or in some other shape. The frame is provided with a downwardly extending portion 13. A web 14 which is tubular in form and closely conforms to the outer diameter of the frame 11 surrounds the portion 13. In order to provide for great strength of attachment, the top edge of the web is folded over so that there is an underlying overlapping portion 15. The upper portion of the web 14 and the overlapping portion 15 are secured to the frame 11 by rows of stitches 16. While the web has. been referred to as tubular, it may be formed of a sheet of material the edges of which have been secured together by stitching. It should be formed of a nonconducting material, and is preferably made of heavy canvas. A relatively coarse material such as heavy canvas is rather stiff and has a high co-efficient of friction. This is advantageous in that when the bucket is collapsed, as shown in Figure 1, the webbing where it is attached to the frame is folded upwardly inside the frame and is engaged with the external surface of the bottom. By' reason of the close t of the bottom 17 with the fran-re- 11, the web 14 at the point of attachment to the bottom will frictionally engage the web 14 at the point for storing, shipping, or carrying purposes.
where it folds upwardly inside the frame 11 (see Fig. l).-
At the bottom of the web, a bottom 17 is attached to the web. This bottom is attached to the web 14 by having the web disposed against the inner side wall of the bottom 17 with the lower edge 18 of the web folded upwardly to form an overlap 19 for additional strength. This web is secured to the bottom by two rows of stitching 20. The lower edge 18 need extend only to the floor 21 of the bottom 17. lt is preferred that the bottom 17 be formed of a single piece of leather molded to have a floor 21 with upstanding, slightly diverging flanges 22 to which the web 14 is secured. While leather is indicated as the preferred material, many other materials, such as breboard, plastics or other relatively rigid fabrics could be used.
In the interest of having the bottom 17 telescoped within the frame 11, it is essential that the external diameter of the slightly-deformable bottom 17, be substantial that of the internal diameter of the frame 11 with one layer the web lying between them as shown in Figure 1. Thus, when the bucket is telescoped, the bottom 17 will form a receptacle for the folds of the web 14, which will substantially lie in the bottom and will push up one layer of the web, so that it intrudes between the bottom 17 and the frame 11 and by reason of the proximity of the said members and the web 14, they will be maintained in frictional engagement with each other and the bucket will remain telescoped during its period yof non-use without any substantial tendency to unfold. 'Through the top of the frame 11, immediately below the enlargement 12, a pair of diametrically opposed holes 23 are provided for the insertion of a handle 24. This handle 24, like the other elements of the bucket, is formed lof a dielectric material such as manila rope with the end portion properly interwoven and spliced to the main portion.
This construction provides a bucket that is compact When the bucket is expanded from its telescoped condition, it is ycompletely safe for transporting tools, supplies and equip- Vment from the ground to the top of poles, towers and other :structures from which are suspended high-tension lines. 'To use a conducting bucket of metal under such circum- :stances is extremely hazardous and my bucket is complete- @ly safe for such usage.
