CARPET-STRIP ANcHonAGE.

Application led October 30, 1922. Serial No. 597,700.

To all whom t may concer/rt.'

Be it known that I, MAHLoN a citizen of 4the United States, residin at Chicago, in the county of Cook and tate of Illlnois, have invented certain new and useful Improvements in a Carpet-Strip Anchorage, of which the following is a spec1- fication.

This invention relates to certain improvements in a means for securing to hardened ioors a strip to which the edge of a carpet may be attached. The anchorage of my intake a variety of forms, and be used wit floor, wall, and partition constructions of. various kinds. The several modifications shown in the' accompanying O. Kassen,

drawings are suggestive of different conditionswlth which the present anchorage may It is a primary object of my invention to provide for the purpose'named an anehorj age which will be secure ,at all times; which may be produced and installed at small expense; and which is adaptable as wellto a variety of 'conditions in building construetion. :These and other objects of my invention will appear hereinaftewfrom the speci` fication and claims to follow, taken in connection with the accompan ing drawings wherein various forms of t e present anchorage are set forth in themanner following:

Figure 1 which represents in cross section the lower portion of a wall or partition extending upwardly from a hardened floor, such as would result from theuse of concrete, shows a carpet strip anchored in place with the aid of a device which embodies this invention; v

Fig. 7 represents in p an an anchorage which exhibits a still further modification; Fig. 8, which is a view similar to Fig. 5, shows another form of the anchorage;

Fig. 9, whichl is also a view generally sim-A ilar to Fig. 5, shows a form of anchorage intended for one strip only when placed adjacent a hollow wall or partition;

Fig. 10 exhibits an'anchorage adapted for use with a slightly modified wall or partition construction; and

Fig. 11 represents a still further modification of anchorage adapted especially for use adjacent an 'outside wall, of brick or masonriiy. f

he anchorage of this invention is adapted for use with building having a construction such, for example, as is shown in Fig. 1,

wherein is shown a concretev floor A from which rises a waill or partitlon B which ma be formed hollow, or otherwise, in accor ance with usual practice. Near the fioor line grounds C are carried by the wall or partition as is also 'a plaster coating -D in flush relation therewith. A base board E is also connected with the grounds in the usual manner, and adjacent thereto is a carpet stripF-of approved design having its rear edge disposed beneath the'base board. A

tongue and groove connection between the base board and carpetlstrip is also shown in certain figures of the drawings, in accordance with common practice, but so far as this' invention is concerned, such a formation may `be wholly dispensed witlnfsince experience has proven that it may not be safely relied upon to hold the carpet strip in lace. A

ith a type of building construction such as has been described, the anchorage of my invention may be employed to special advantage. As shown in Fig. 2, it may consist of a plate 10 having ton ues 11 struck up from its body at points w ich are equidistant from its ends andspaced apart from each other about the thickness of thepartition r tile; in addition, each plate end is formed with aplurality of pointed teeth y12 which upstand for a desired distance. Asshown, these erid wings are three in number,` and may rise from the Hoor i n the mannershown, or otherwise. By spacingv the two ton ues 11 so as to lie adjacent opposite sides o the tile, the anchorage will be so centered as 1e upon the oor and extend through or below the wall or partition whichv asv 'may beoiset so that the middle wing is his los

lio

to project its opposite ends for an equal distance on each side of the wall. After erecting the Wall or partition, a carpet strip may beK arranged on each of its opposite sides being driven to position over .the pointed teeth atthe plate end, by which action the teeth become embedded in the strip. By offsetting these wings in the manner shown, I practically eliminate all possibility of the wood cracking or splitting during this operation. This strip in these circumstances is held securely in place' upon the floor and may not be pulled away from the partition even when subjected to the very severe strain imposed by a carpet which is secured thereto in the usual'manner. The addition of the base board E as is customary, is primarily to present a finished appearance` but need not in any measure contribute to the present anchorage except in so far as it may act to prevent its working upward and thence 'off i of the teeth which grip therewith.

In Fig. 3 I have shown a` slightly modified anchorage construction which is especially adapted for use adjacent an outside wall B, such, for instance. as" is formed of. brick. With such a wall 'is associated the usual grounds C, plaster coating D, base board E,

and carpetstrip F, all as previously explained. Ananchorage forthis latter part,

however, may conveniently comprise a plate 15 havinn' upturned teeth 16 at one' end thereof, the oppositepla-te end being downwardly turned as at 1t to'provide in effect a flange. In the plate body, it may be preferred to form one or more holes 18 and likewise otherholes 19 in the flange portion thereof. An anchorage answering to this description is designed for installation previous to hardeningr of the floor so that its flange may be embedded therein in proximity to the wall. In such a construction the concrete or mortar isA free to enter the holes-18and 19, thus adding to the security of the anchorage. Because each plate is located close to the wall. it follows that its teeth are lcorrectly positioned relative to the strip which `is thereafter hammered down thereupon in the manner already' explained. A construction such as this, provides a se.- cure anchorage for the strip such that it will not be displaced through pull of the carp\e`t when attached thereto.

T he anchorage forms described up to this point may be modified in certian particulars without sacrifice of the features underlying this invention. In Figs..5 to 11. inclusive, are set forth certain forms which the anchorage may take. these being offered as typical of various changes in form, shape, and contour which may advantageously be employed according to the conditions created by the building construction with which the anchorage must co-operate.

lThe anchorage shown in Fig. 5 is adapted 'A for use with a wall construction similar in all .respects to that shown 1n Fig. 1, and accordingly the parts which are common to .the two figures bear like reference numerals. The anchorage per se consists of a plate 20 adapted to berested onthe floor with its ends extending laterally to each side of the wall or--partition- At each plate end is an extension tongue 21 which initially protrudes beyond the forward edges of each carpet strip. Upstanding teeth 22 are provided at each end of the plate body in position to enter the carpet strip when the same is driven down thereupon, as shown in Fig. 5. The platemay-take the form which is shown in Fig. 6 with its tongue 2l extended from a middle position at each plate end, in which event the teeth lieto either side thereof. lith such van anchorage` the extremities 23 of each tongue may be bent upwardly and around so as to be clinched down upon the carpet strip in the manner shown in Fig. 5. Such a lconstruction serves to reinforce the connection' between the carpet strip and the anchorage which is provided therefor.

In Fig. 7 I have shown in plan an anchorage having many characteristics similar to that just described in connection with Fig 6. .In this construction use is made of la plate 25 whose extremities 26 are adapted to extend out beyondv the forward edges of the two carpet strips. Thereafter these extremities are bent up and around so as to be clincheddown upon each strip in the manner described in connection with Fig. 5. .Such an anchoragedepends solely upon its clinched connection with the two strips to hold-the same in place, inasmuch as I have not provided any teeth for gripping the strips. It should be borne in mind. however, that the teeth may be added to this construction, in which event an. anchorage ,very similar to Fig.l 6 would result. Likewise if the tongues of Fig. `6 be omitted, the result will be an anchorage very similar to that of Fig. y2. The tongues 11 shown in this latter-figurewhich serve to center the plate relative to the partition, may or may not be used, according as is desired, the construction of Fifr. 6 suggesting a construc- -tion where suci tongues are wholly dispensed with.

Referring now to Fig. 8, the building construction therein showniis in all respects similar to that indicated in Figs. 1 and 5, excepting that the wall or partition is indicated as hollow so as to present inner wall surfaces 27. rIhe anchorage used in such a wall may follow identically that which is shown in Fig. 2 with the one exception that the tongues 11 are .shown as spaced closer togetherso as to lie adjacent theinner surfaces of the partition rather than the outer surfaces thereof. This difference, while trifling, is nevertheless suggested at this point, as indicating one further modification which, in some cases, may be preferred. In this same figure the several teeth 12 are shown as struck up in the same plane, insteadI of being offset. It is not considered that this is to be preferred, but is represented as indicative of a possible modification, although very slight, from the exact form shown in Fig. 2.

Fig. 9 sets forth a wall or partition construction in all respects similar to that of Fig. 8, it being particularly noted that the partition used is hollow. The anchorage in this case is intended for holding a carpet strip on only one side of the wall or partition. 'lhis being the case the plate 3b therein shown is formed with struck-up teeth 31 at one end in position for embedment in the carpet strip, and at its other end is provided with an up-turned Harige adapted to rest against one of the inner faces of the wall or partition. In this construction, as elsewhere, the carpet strip backs up to the base board, so that it may not be further moved toward the wall or partition, while the anchorage which bears against the Aproximate inner face of -the partition serves to hold the strip against outward movement therefrom.

It may be desired to utilize m invention with wall or partition constructlons wherein a combination base board and border is vused. As an example of this I have .represented in Fig. 10 a wall'or partition B rested upon a floor 36 of concrete, a base board 37 being arranged at the juncture of the wall or partition with the floor line. This base board combines in its construction a border section 38 which is suitably supported upon a base of mortar or cement. lVith such a con uction it is common to mold the floor rwry'th a groove which is thereafter filled by rout or mortar 40, as shown.

A wall and floor construction 'answering to the preceding description imposes special diliculties in the way of an anchorage for a carpet strip F such as is shown in juxtaposition to the border section 38. To an- -vchor such a strip in position I employ a plate 41 one portion of which 'is rested on the fioor beneath the border section 38. The end 42 of this plate portion is suitably formed for embedment in the mortar, a flange being suggested for this urose. The other end of the plate is provi ed with a propriate teeth which are adapted to e driven into the carpet strip when the latter is pounded thereupon. As shown, one of these teeth 43 may be elongated to project clear lthrough the carpet strip, permittin its extremity to be downturned or clinched thereupon. lVith suchl a construction the carpet strip is most securely held in place. l would have it noted that this provision of an elongated tooth whose extremity projects through the upper side of the strip, thereby adapting it to be clinched thereupon, may be employed with equal advantage with any of the other constructions herein disclosed.

Another type of building construction where special difficulties are interposed in the way of an anchorage for the carpet strip is suggested in Fig. 11. In this case, I have represented a wall or partition'B which may be made of brick-or concrete.

The' floor in this construction is shown as monolithic, its ends being partly received and supported within the wall, as shown. The carpet strip in this case is anchored with the aid of a plate 45 having upturned teeth 46 adapted for embedment therein when the strip is driven down thereupon.

As shown, the plate is provided with an up- `wardly extending ton ue 47 struck from its body, and adapted to ear against the proximate face of the wall or partition, thereby centering the anchorage in relation to the strip which is to be held. This plate which is rested upon the floor may be provided with a crimped or corrugated rear end portion 48, or be otherwise formed in such a manner as to adapt it for reception within the mortar space which underlies the first brick that 'is rested upon the floor. When the mortar is finally placed in this space, the plate will be securely held against displacement so that a firm anchorage for the strip is provided.

It will be understood that the various formsv of anchorage herein described will each consist of a plurality of plates that are positioned along the wall or partition at desired intervals so as to effect a secure connection with the strip. Devices of this character may be produced with the aid of dies at small expense, and possess the advantage of being readily installed as the buildin operation advances. In accordance wit common practice the base board is adapted to lover-lie the rear edge of the strip, and because of this relationship of the parts the strip cannot work loose from its anchorage unless the base board be first removed/ to permit the necessary movements for this purpose.

I claim:
