L. C. LETZKUS SECTIONAL RUG PAD Filed Sept. 24. 1925 Patented ea. 28, 192a MEN SECTIONAL nus PAD.
Application filed September 24, 1923. Serial no. 601,648.
To all whom it may concern: 1
Be it known that 1, L110 0. LETZKUB, a citizen of United States of America, and residing at Pittsburgh in county of Allegheny, State of Pennsylvania, have invented a new and useful Improvement in Sectional Rug Pads, of which the following is a specification.
My invention relates to sectional rug pads for deadening the sound and preventing the wear of rug and refers particularly to such a form of rug pad which can be used permanently and can be speedily placed under a carpet or rug and when so placed will be perfectly sanitary and dust proof.
The object of my invention is to provide a cheap, simple rug pad which can be made up in sections to fit any size rug or carpet and which can be collapsed or folded into a neat form for transferring from point to to provide a sectional rug pad which will be sanitary and moth proof and which will not need to be fastened or tacked to the floor, and which will not be torn or harmed by a vacuum cleaner passing over same, and which when not in use can be folded neatly and packed away in a minimum amount of space.
My inventionis designed primarily to eliminate the present inefiicient method of padding'carpets and rugs so often used at the present time and to provide a pad which will be practically as permanent as the rug or carpet under which the same is used.
My invention consists, generally stating, in the novel arrangement, construction, and combination of parts as hereinafter more specifically set forth and described and particularly pointed out in the appended claims. To enable others skilled in the art to which my invention appertains to construct and use my improved sectional rug pad, I will describe thesame more fully, referring to the accompanying drawing, in
which Fig. 1 is a perspectlve view of a section 0. my rug pad containing three units.
Fig. 2 is a partial top plan view showing the method of hinging or lacing the units together v 1g. 3 is a cross sectional view taken on the lines III-III of Fig. 1.
Fig. 1 is an end view showing three of the units folded together.
Like symbols of reference herein indicate like parts in each of the figures of the drawmg.
As illustrated in the drawing m improved rug pad is preferably forme into binding is individual as to each unit and,
is for the purpose of efficiently sealing the chamber 7 aga nst the admission of any dust or other foreign substance.
While I have shown the three sections in Fig.' 1 on the drawing, I do not limit myself to any particular number as sizes and shapes of rugs or carpets will necessitate the regulation thereof to actual conditions.
The units are hinged together by strong heavy cord which is laced through the tape or fabric 8 on the ends of the units and is cross-laced in order to provide a suitable hinging member which will permit of each unit being folded over in either direction onto or below the successive units. This method of stitching will be started b passing the strand of twine 9 doubly t rough the ends of the units to be hinged and on the second turn the two ends 10 and 11 of said twine will be crossed and then will be brought through opposite sides of the ends of the respective sections, passed across the joint of the same and again brought u on opposite side of the respective units. his method of stitching or hin ing will give a very effective hinged joint of double strand with a single piece of twine 'or cord.
By this form of hinge the upper faces of the units 2 and 3 and the lower faces of units 1 and 2 can be folded together and units will lie close together as the strands.
of the stitching will slide through the openin s provided for the same by the stitching.
%Vhile I have shown this particular method of stitching as the one preferably to be used in my improved rug pad, I do not limit myself to this method in particular but various modifications and changes in the manner of joining the units together with a cord or twine may be resorted to within the scope of the appended claims, without departing from the spirit of the invention or sacrificing an of its advantages.
What I claim as my invention and desire to secure by Letters Patent is:
1. A rug pad comprising a series of units, each unit consisting of two flat sheets of material, a corrugated member interposed between the same to provide a cushioning member, and a laced hinge member joining said units together. r
2. A. rug pad comprising a series of units 20 each unit consisting of two flat sheets oi material, a corrugated member interposed between the same to provide a cushioning member, and a laced hinge member joining said units so that the strands of same may 25 slide therein to allow the faces of said units to be folded together.
In witness whereof, ii, the said Lee C. Ln'rznns, have hereunto set my hand in the presence of two subscribing witnesses.
