anchor which is separate from the strip and is .insertable throughthe latter to provide lugs on opposite sides of the strip.

A further object of the invention is to provide anchoring plates which may be engaged with the stripsin a facile manner and are secured thereto to prevent accidental displacement of the plates. 7

Coordinate objects of the invention are to provide anchors which are engageable through the strips at any point intermediate the longitudinal edges of the latter to prevent lateral displacementof the strips to provide anchors of this character which are engaged with the strips in such a manner as to provide gauges to automatically regulate the depth of penetration of the strip into the screed coat and correspondingly to define the thickness of the terrazzo which is laid on the screed coat; to provide anchoring plates which may be quickly engaged with the strips and are secured thereto to prevent relative movement of the plates and strips; to provide anchoring plates which not only serve as anchors and gauges in the manner set out above, butwhich may likewise be used to unite adjacent strips together in orderto eliminate relative movement of the adjacent strips; and to provide anchoring plates or .35 gauges which are relatively flat and are sep arate from the strips which permits the strips and anchors to betransported separately, the construction of the anchors being such as to permit assemblage of the same with the strips on the job.

Other objects of the invention will be apparent from the following description of the present preferred forms of the invention, taken in connection with the accompanying drawings, wherein V Figure 1 is a fragmentary top plan view of pattern and guide strips constructed, in accordance with the present invention, illustrating the application of certain forms of my improved anchoring plates thereto;

Figure 8 is a fragmentary perspective View of a pattern strip, adapted for there ceptionof a bifurcated anchor plate.

In the use of guide and pattern strips, it is customary to first pour a plastic composition, 1 known asqthe' screed coat or layer, upon'a solid foundation and when the consistency of the screed coat has changed into a semi-plastic condition, the strips are placed in a vertical position and one of the longitudinal edges thereof urged into the screed coat. It is customary in the art to strike out or otherwise integrally form anchors on the strips which tend to stabilize the latter and, in addition, limit the extent of penetration of the strip in the screed coat. The top layer, such as terrazzo, or the like, is then laid on the screed coat above the anchors, the top of the terrazzo being flush with the upper marginal edges of the strips. T he strips in this way tend to unite the screed coat with the upper mosaic coat in a manner well-known in the art. It is the purport of the present invention to make the anchors separate to permit sliding the same transversely through the strips in order to provide anchoring elements at directly opposite points on the strip, to eliminate the possibility of lateral tilting of the strips; Moreover, the anchors are relatively narrow to reduce the surface area to be impinged by the plastic material to eliminate. the possibility of distorting the strips. I have herein illustrated different forms of anchor plates which serve not only to anchor the strips, but likewise to act as height gauges,

' some of the ,fOl'DlS of which are capable of uniting the strips together.

- 7 In the'drawings, strips 9 are shown which are preferably inadeof brass and are of standard construction, except 'for the provision therein of openings generally designated 10.

The openings may be single or double, de-- pendingtupon the configuration ot'cthe' plate used, as more fully hereinafter described.

' drawin s.

Moreover, the openings may be arranged along the longitudinal center "of the strip or may be offset fron the longitudinal center in order toincrease or decrease the thickness or the upper inosaic layer. ,The'openings' are:

elongated, extending" horizontally to correspoi'idingly position the plates inserted therethrougl'l so that the upper and lower facesof the plates Will be parallel to the'lonfgitudinal 'edges oft'he strips,

- The preferred forni of'plate, as illustrated to advantage in Figure 3,- cousists of web-- long .bec- 1 1, one-end of which is bifurcated to. provice fur-cations 12. The fur'cations are adapted for use ina variety of Ways. I For instance, the fifurcations may beinserted. through twin slots or 'o aenin'gssuchas shown in the strip illustrated in Figure 8 of the When used in this Way'the opposite ends of the plate on each side of the strip are equi-distant from the opposite faces of the latter, to provide oppositelydisposed lugs the lower faces of which are adapted for impingement against the upper surface of the screed coat, while the upper faces thereof are adapted to receive the outer or niosaiecoat thereon. Ihe bight betw en the intentions is adapted to receive the-plastic Z material therein sons to lock the anchor plate from displacement. The bifurcated plate" may also,'as illustrated in Figures 1 and 2 of the drawings, be used to connect adjacent right-angular strips together. When used in this way, the furcations 12 are inserted through twin slots formed in one of the strips Tand will straddle the terminal of'the' adjacent strip. Theadjace'nt strip fits in the bight between the furcations and abuts the r ight ang.

Hular strip which carries the" anchor plate.

Thebifnrcatedplateinay also be used to connect adjacent guide strips which'are arranged in end toend relation, as shown in Figure 3 of the drawings. lVhen used in this manner,

the furcations 12 of the plateare engage-able through complemcntal openings formed in the adjacent. ends of the strips to thereby efl'e'ct a'loclting'engager'nentof the latter. When the anchor plate is used in this manner, the

plastic material is permitted to gravitate through the bight between the furcations to I lock the anchor plate frorn displacement! It i is desired to the plate withnieansby "which it is seemed-to the strip or strips and it has been found desirable, for this purpose,

or slots in the strips through which the plate 7 passes. The protuberances used on the plate ll co'nsist of longitudinally extendingiribs 7 13 Whichare pressed outw'vardly through one face of the plate; Preferably the protuberances extend for anappreci'able distance mid way the euds of the plate, to exten'dcompletely across the siots or openings in the strips in which the anchor plates are engaged.

This'ionn of plate is provided with longitudinally extending rotubermces 18, formed on opposite sides of the tongue 17.

The plate 16 is adapted for insertion horizontally through the guide strip and is used in'the same manner as the platesfll and 14. The plastic material is permitted to ss through the opening .19 formed by stri hg out the tongue 17 to further lock the plate 7 from displacement.

In the for'rn of invert tionshmvnin Figures 6 and 7, a plate desigj1'1ated20,is employed, whiclii's equipped with a pa r of tongues 21, used inthe same manner as the tongue 17 In addition, the plate 20 is equipped with a stud or protuberancQQ, which coj-acts with the tongue 2 1to prevent longitudinal movement of the plate through the guide strip 7 i In using border guide strips, sufiicient space anchor plates in order to reduce cost to an absolute minimum,

Although I have described herein the pre ferred forms of my invention, it is, nevertheless, to be understood that various changes may be employed in making upthe anchor plates and associating them with the guide and pattern strips in harmony with the teaching of the present invention. It is of the essence of importance, however, that the guide strips he provided with slots or openings which are adapted to receive anchor plates extending transversely therethrough in a horizontal plane, and so constructed that they wi ll be locked from displacement in the strips. The bifurcated anchor plate constructed in accordance with this invention not only serves in the capacity of an anchor plate and gauge, but when used as set 'outherein, it serves to positively lock adjacent strips together and prevent relative movement thereof, which has been a source of anno ance to worlnnen in' laying floors of this-kind heretofore.
