Patented Dec. 24, 1929 UNTED SITES HAROLD J'. MGRE, 0F MIDDLETOINN, CONNECTICUT BUFFER FOR CLEANING AND SIMILAR TOOLS Application filed october 19, i926. Serial No. 142,588.

My invention relates to the class of devices that are employed to prevent mai-rino' of polished or finished surfaces, as furniture, baseboards, etc., and an object of my invention,

among others, is the provision of a device of this class that shall be particularly etlicient for the purpose for Whrh it is intended.

One form of bull'er embodying my inven tion and in the construction and use of Which the objects herein set out, as Well others,

may be attained is illustrated in the accompanying drawings, in Which- Figure l is a View of a cleaning tool provided with my improved buffer.

Figure 2 is a view, scale enlarged, of a fragment of my improved butter.

Figure 3 is a View in cross section through the same.

Figure d is a view in section on plane denoted by the dotted line e't--l of Figure Figure 5 is a view in sect-ion on plane denoted by the dotted line 5 5 of Figure il.

The scale in Figures el and 5 is greatly eX- aggerated.

A common form of cleaning tool employed at the present time, is of the type known as a pneumatic cleaning tool and in the use of such devices upon floors and similar places it is essential that means be provided to prevent the marring of furniture, baseboards, and other parts by Contact with such tools in their operation. Various forms of buffers have been employed, such as those of felt or similar soft material or rubber in various forms. These have not proved highly satisfactory for the reason that they Will soon become inellicient by reason of stretching so that they will not be retained in place, or by reason of so much give that the tool may be brought into contact with the finished surfaces.

It is a purpose of my invention to provide a structure that, While having the necessary elastic qualities, will enable it to endure for a long period, yet at the same time have the necessary features requisite for a buffer to prevent marrin g of polished or other finished surfaces. Such a structure is shown in the accompanying drawings, in which I have il- 5 lustrated my improved buffer in connection with a cleaning tool denoted generally by the numeral (l. rthe head 7 of this tool is provided with a Groove 8 in which my improved butter 9 located.

This butler is composed of a combination of threads suitable for buffer purposes and threads for imparting elasticity to the structure. Such a structure may consist of Wea-ves of various sorts, but a Weave that I have found particularly adapted for this purpose comprises one embodying the characteristics of what is known as a bon weave, and which Weave I have adapted for my purpose by iinorporating the elastic threads as hereinbefore mentioned, together with means for maintaining the position of such threads and thereby preserving the form of the strip from which the buffer is made.

rlhis fabric comprises warp threads l0 and weft threads ll which may be Woven in many di'lferent ways to accomplish my purpose, my invention embodying elastic threads l2, which will generally consist of rubber, comprising a part of the warp. These elastic threads may vary in number and in arrangement, as may be desired, in the form herein shown there being two layers of such threads extending substantially across the strip. In order to prevent these elastic threads from distorting the strip, or, in other Words, to maintain the form of the strip, I provide holding threads 13 that are passed preferably across the strip in the direction of depth thereof. These threads may be arranged in various Ways, an arrangement which I have found satisfactory comprising ay holding thread located between each of the vertical rows of elastic threads l2, which rows in the present instance each have two threads and which holding threads are anchored to the weft threads in any suitable manner, as by passing the holding threads entirely through the fabric or strip, between the Warp threads 10, and over and between the filling or weft threads 11, and as shown especially in Figures 4 and 5 of the drawings As hereinbefore stated the general Weave may be of many different types and the elastic threads and holding threads therefor comprising my contribution to the art may be arranged in dilferent Ways, my invention embodying the incorporation of the elastic threads for imparting resiliency to the strip and the holding threads for maintaining the elastic threads in position and thereby maintaining the Jform of the strip, especially in cross section, that herein shown providing a strip of substantially rectangular form in cross section.

In accordance With the provisions of the patent statutes I have described the principles of operation of my invention, together With the articles Which l now consider to represent the best embodiment thereof, but l desire to have it understood that the article shown is only illustrative and that the invention may be carried out by other means and applied to uses other than those above set out.

I claim- 1. A buffer strip comprising Warp and Wett threads Woven into flat tubular formation with the Warp threads omitted at the edges in the Warp plane ot the elastic threads, a double layer of elastic threads Woven into the bore of said formation, and helder threads separate from the -Warp threads Woven through the strip in parallelism With the Warp threads and spanning on the surfaces of the strip a dilerent number of weft threads than the span of the Warp threads.

2. A buffer strip comprising Warp and Wett threads Woven into double ply tubular formation, a double layer of elastic threads Woven into the bore of said formation, and holder threads separate from the Warp threads Woven through the strip between the elastic threads in parallelism with the Warp threads but spanning in each ply a different number of Wett threads than the span of the Warp threads. y
