Patented Nov. 1, 1932 UNITED STATES SAMUEL STEI1\l'.'/1I]EYPZ,V OF KISPEST, HUNGARY DOORMAT Application filed June 30, 1928, Serial No. 289,577, and in Hungary October 15, 1927.

This invention relates to improvements in mats, and has for its object to provide a mat of the type ordinarily located at a doorway including a grating provided with cleaning elements and a dirt collector thereunder, the

grating being inserted in a grid-like underwith parts removed, of the grating'or framev structure provided with cleaning elements; f

ao Fig. 2 is a similar view of the grid-like underframe;

Fig. 3 is a fragmentary perspective view, with parts broken away, showing the two separable parts of the mat assembled;

Fig. 4 is a detail view in top plan of a part of a modified form of mat; p

Fig. 5 is av detail section on the line 5-5 of Fig. 4';

Fig. 6 is a fragment-ary section similar to 80 Fig. 5 showing further modification of the invention.

Referring to the drawing in detail and more particularly to Figs. 1w?) thereof, the grating A provided with the cleaning elements g and the grid-like underframe B are constructed in such manner that the two parts may be rolled up separately or together as,

for instance, when storing or transporting or Y when removingV the matfrom the dirt cleaner (not shown) during the operation of cleaning the mat.

The grating or frame-like part A of the mat is composed of flexible strips t of leather, rubber or equivalent material to which pairs of brush bars el and e2 are secured by retaining members 1 into which the extremities of the brush bars are removably inserted. Brushes g are suitably attached to the bars el and e2 and the latter with the brushes g may be conveniently and compactly folded with the flexible strips t as a unit or in conjunction with the other part B of the mat.

The part B is composed of flexible strips t similar to the strips t and to which are secured pairs of bars the bars of each pair being arranged to accommodate in the space 01 therebetween, a pair of brush bars el and e2 and the bars Z) of the respective pairs being spaced apart as indicated at 02, thus providing an open skeietondike underframe.

Although it is preferable for convenience in rolling the mat to form the strips and t of flexible material, it will be understood that these parts may be replaced by rigid frame members.

y In the form of the invention illustrated in Figs. et and 5 the retaining members l for the brush bars el and c2 are secured to strips t and provided with 4recesses in their upper portions of the same shape and accommodating the dovetailed extremities cl3 of said bars, the latter being retained in position in said recesses by longitudinally displaceable cover plates 1 confined in position by clips or loops Q suitably secured to the members l. By removing Vthe cover plates l the brush bars el and e2 may be removed or interchanged as desired.

In theV form of the invention shown in Fig. 6 the retaining members l recessed as inFigs. 4 and 5 are provided with hinged cover plates 1 by which the brush bars are held in position.

The spaces 01 and 02 between the bars b of the underframe B and the brush bars 'el and e2 permit the matto be conveniently rolled as a unit when so desired, the bars b being slightly less in length than the distance be tween the retaining members l for the brush bars. It is also desirable to secure cushioning elements ci between the brush bars el and e2 of each pair to maintain these latter in spaced relation to prevent the collection of dirt upon the bars. As the brush bars are fastened only at both ends they are subject to deformation Vwhen pressure is applied thereto as when treading upon the mat, the extent of deformation possible being suggested in Fig. 3 where one of the brush bars indicated by the vertical arrows is shown in a lower position than its companion bar. When treading on the mat the deformation or bending of the brush bars relatively to the bars b of the underframe disposes the bristles g below the plane of the bar thereby protecting the bristles against mutilation and causing the bristles to be cleaned.

What I claim is:

l. A mat comprising' an under frame including a plurality of spaced bars and llexible means connecting the ends of the bars7 and an upper frame including a plurality of spaced parallel cleaning elements and flexible means connecting the cleaning elements, said cleaning elements being removably positioned between the bars.

2. A mat comprising an under frame including a plurality of spacedparallel bars, means connecting` said bars, an upper frame, placed on the under frame and adapted to be lifted therefrom, said upper frame includinga plurality ofspaced parallel cleaner bars arranged in pairs and carrying bristles7 means connecting the ends of said cleaner bars, each of said pairs-of cleaner bars being' arranged between two adjacent bars of the under frame7 and means for maintaining the cleaner bars in spaced relation.

3. A mat comprising an under frame including a plurality of spaced parallel bars and means connecting said bars7 an upper frame placed on the under frame andadapted to be lifted therefrom, said upper frame including a plurality of snaced parallel clean- .er elements fitted between the bars of the under frame, llexible strips connecting the ends of the cleaner elements, and carrier members on said strips detachably receiving the ends of the cleaner elements,

In testimony whereof I have sioned my name to this specification.

SAMUEL STEINIETZ.
