devices for retaining rugs, carpets, 'and like articles of'loor-covering in adjusted position when placed loosely upon theloor and for retaining such articles in their ori al sha e by preventing the. curling of the e ges, which so vcommonly occurs in these fabrics after long use.
The object of my invention is to provide a device of the class just described'which will oifer a maximum of resistance toaccidental dis lacement and to the tendency onthe part of t e fabric .tb curl or otherwise lose its origin'al shape with the minimum material and at a minimum cost and to provide such a device which will be-chea in manufacture, simple in construction, an eflicient in operation.
My rug-holder is homogeneous in structure and is made of a single iece of rubber provided with an edging of abric or other ysuitable materialformed with needle-holes for the passage of the thread which binds the holder to the rug. By using'the one material-rubber--homogeneit of structure is obtained, all cements are dispensed with and the life of lthe structure is lengthened, and va light, comparatively cheap, strong, stiff, and resilient holder results, having all the natural adhesiveness of rubber without the defects of l the spring-steel rubber-coated combinations .o now on the market.
In order to distribute the material of the holder to the best advantage for the purposes in view, the holder is made in the form of an arrow, the head of which is provided at the point with a bulb which is in line with the shank, the latter extending diagonally back toward the center of the rug, wh1le the arrowhead iitsy into the corner of the rug.' Thus if the toe of a shoe worn by a person walking in o the room should strike against the holder the blow would naturally be received by the bulbous point of the holder and by it transmitted in a direct line to the shank, which by reason of its long lever-arm would resist the tendency 5 to displacement and restore the rug to its 'speci'ncation ef Letter Patent. appunti@ alea nioh 1, 190e. seala. 309.609,

mogeneous nature of the material of which the shank of the'holder is made and its sti'ness combined with resiliency (it vwill be under. stood that the deviceis suitably vulcanized) all aid to make the device most efficient in operation.
process of moldin lt e iirml securing the older to the rug are provide `dand the disadvantages of passin the thread through the rubber of the holder ltself' are avoided.
- In the drawings illustrating the' principle of my invention and the best mode now known to me of applying that principle, Figure -1 is a plan view of the bottom of a rug having attached to it rug-holders embodying my invention. Fig. 2 is a plan view of the floor side or face of my rug-holder; Fig.3 is a modified form of whatis shown in Fig. 2, and
my rug-ho der.
The body ortion or head va is'molded in one piece withJ the shank b and in the process of molding the edging d, of fabric or other suitable material, 1s inserted and becomes thoroughly embedded in the matrix of rubber, so as to be firmly secured to the molded holder, from the head of which it projects along the sides thereof. Through needle- ,holes e, formed in the edging d, a bindingthread is assed to secure the holder to the rug f, as il ustrated in Fig. 1. By fthe provision of the edgi d the thread does not have to be interposedletween' the floor-face of the rubber-holder and the floor, and thus is pre-l served all the natural adhesiveness of the rubber face. Further, the holder is much more expeditiously secured to the ru and the thread'is not hable to rot out, as when in contact with rubber. The floor side of the holder is represented .in Fig. 2, while a modified form thereof is shown in Fi 3. In Fig. 2 the lower face of the holder 1s illustrated as rovidedl with points pro'ecting outwar y therefrom, and in ig. 3 t e squares or blocks h are substituted for the points g. These oints g and blocks h sustain the pressure of the weight of the overlying material and adhere firmly to original adjusted position. Further,th'e.ho-

f Fig'. 4 is a'lplan view of the top or rug side of- A IOC .los
the floor, providing a frictional surface which resists blows tending to displace the rug and also overcomes any tendency of the fabric to .slide along theloor.
The rug side or top of rthe holder, Fig. 4, is iiuted, the lines i j being slightly raised above the surrounding level. These lines are shown in two sets, the lines of one set running in a different direction from the lines of the other set. The lines engage the rough under surface of the rug, carpet, or other fabric, and thereby overcome the tendency of the fabric to curl, creep, `or otherwise change its original sha e. On one side the holder :adheres to the Y oor and -on the lother side closely .to .the rug..
The point lof the head a is formed with :an enlargement :or bulb c, which lies directly in line with the shank t. This bulb c .adds very materially to the stiffness and strength of the structure, both of which are cardinal points in these devices. The bulb c i's naturally in a position to receive blows tending to displace the rug and transmits such blows to the 'shank b in a direct line, the shank b by its stiffness and resiliency, cou-pled with a long lever-arm, resisting the tendency to displacement :and restoring the rug to its origij nal adjusted position.
I am aware that metal devices of this class have been made pads :of soft rubber attached to them to give a frictional surface; but such devices do not possess the durability of my holder, as the rubber and metal frequently separate -alonlr the layer .of cement used to join them, and the rubber is liable to crack and break off, due to the unequal bending of the metal and rubber. My holder is perfectly homogeneous in structure, being made up of one piece v,of molded rubber.
I am also aware that devices of this class are already upon the =market in which a joint exists between the head or body portion and the shank member. In my holder the shank is integral with the body portion and Weaknessl `and lack of stiffness `due to joints are avoided, while the required flexibility and resiliency are obtained by the mise olf rubber as a material.
The piece of fabric which forms the edging d may extend throughout the holder from side to side thereof, t ereby oHering a large surface for the binding action of the rubber to act upon and serving to strengthen the structure as a Whole.
As shown in the drawings, the iiuting on the rug side of the holder (see Fig. 4) is very slightly raised above the'edgin d, and Ithe latter .and the iiuted surface `are rmi-ght into close contact with the under surface of iihe rug.. On the lother hand,(-see 2 and 3,) the blocks or profections lon the ioor side of Ithe holder exten a comparatively long distance from the -edgin d and serve to raise the rug some distance om the floor, thereby serving to prevent by their natural adhesiveness any slidin` of the rug .at the corners. The thickness o the body portion or coating below the fabric d is march greater than that of the body portion or coating above that fabric :on the rug side 'of the holder, as -be readily seen by comparing either Fig. 2 Vor Fig.. .3 with Fig. 4.
41. A rug-holder made up .of .a single piece of rubber molded into shape and having -a l body portion and :a shank extending from said bodywportion, and an edging of lfab-ric molded with said body portion :and proj-ecting therefrom for attachment to the rug.
2. A rug-.holder made up of a single piece of rubber rmolded into shape and having a body portion provided with corners and :a shank extending from said body portion; one of said corners being formed with a bulbous enlargement in line with said shank.
