provement in Ties for Anchoring Floor Sleepers, and declare,thetollowingto be. a liull, clear, yand exa-et description ot the. same,

l such as will enable others fslrilled'in the art to which :it pertainstoinale land use k; theV same, reference being had to the1acoenipany ing; drawings, which forma ypartent this speci'lieation.

lt'ly invention relates toan',improvement in ties for anchoringrloorsleepers to a con crete -bed or z slab. i

In laying wooden flooring upon ,a concrete base it is essential that thei floor sleepersf-.fto which the wood flooringl is nailed,-fshou:ld be securely `anchored against displacement upon the concrete bed orbase. Heretofore it has been customary to insert a plurality oli metal strips in the concrete bed or-basev while the latter is in a plastic condition,-,the strips lbeingw embedded so that they may project above the plane .oli the; bed for attachment to the floor -slcnnpersl This device has been oundobjectionable because of the difculty in inserting and lin ing up the strips in the concrete bed, and furthermore it requires the workman to walk over the plastic `surface of the concrete bed, rst to embed the strips in the concrete and then to nail them to the sleepers laid upon the slab ;-and asv the surface of the concrete slab may be more or less uneven it is difficult to properly align the strips so that their upper edges will be on an even plane` y To overcome this and other objections is the purpose of this present invention which consists of a device constructed of sheet Inet-al in the torni ot a yoke with corrugated walls extending downwardly and projecting laterally from each side of the sleeper to provide bonding ineans whereby it inlay not become separatedfroin the concrete filling, which aflordf-ia; sullicientxband1` to ;iinsuratheglanchor plate being ,securely ahold thy the concrete illing. j v

A further object of the invention is to prio vide` a device which is. not, tapete be tipped when lodged inthe sleeperathrough work-` neenl walking; :overthe ,surfaeerori .due to; the

concrete :filling i, itself when L :poured 1,.,bettveen the. sleepers., eausingftheanchors ,to f tilt1-by the weight ,of the; lilling if: tilled nnequally OnbeCauseonaside ot the sleeper receives the' filling betere the other gw-the :narrow :edge of the device `not `offering suieientsurlace tor the :concrete flillingto lodge uponawherebyit may `-be 1- tipped i nnevenly 'i in i. theosleeper.

1With the foregoing and other objectsiin view ,which will Vappear lathe-.description proceeds` the: invention,` 'further resides in the details of constructionz` hereinafterdescribed and claimedr itbeing funderstood 'that changes inay be. urna/de; in' the precise ambodilnent` of the 1 :invention:v herein :disclosed without dci parting from, the spirit. ofrthefsarne.

ln the vdrzmuings ,aooompanyingfthis speci-y .through a plurality ot sleepers fitted with anchor `or tie plates as shownl in Figure l,

the slab between the sleepers being covered with concrete substantially level withthe topv yof' the sleepers, upon which is secured a wooden `flooring.

Fgure is a fragmentary plan View of a concrete bed, showing a. pair or sleepers with theanchor plates in,` position.

Figure 4 is a perspective view of a modiication in which the corrugated side walls of the anchor plate are iniperforated in counterdistinction to the form shown in Figure 1.

Referring now to the letters olf refer--r ence placed upon the drawings:

` A, denotes a concrete bed or slab as usual-` ly prepared to receive the wooden floor sleepers B, placed thereon in spaced relation to cach other. V

C, indicates a sleeper tie, or anchor plate constructed of sheet metahits cen'tral bridge portion C being adapted totenter a transverse. lerf out in the to'p of the sleeper.

The depending portions Cb of the anchor plate adjacent the side walls of the sleeper are corrugated as shown` at CC toincrease E designates a wood flooring secured to thesleepers B. J

Cf represents Aslots formed in the side walls of the anchor plates through which the concrete filling may pass to increase the bonding surface. i f

When embedding the'tie in the floor sleepv ers it is not necessary to' 'cut a lerf of a depth equal to the width of the bridge connecting the depending sidel portions of the anchor plate together, as all that is required `isto make the cut suciently deep so that the edge oi' the tie may be embedded that it may be driven flush with the top'of the floor sleeper by. a blow of the hammer. After filling the spaces between the sleeper with concrete the flooring may be ynailed to the sleepers.

It will be noted that in the use of this device it is not necessary for a workman to walk over the concrete slab to nail the ties to the sleepers, nor are the anchor plates apt to be disturbed by workmen walking over the concrete, or before the concrete filling is poured between the sleepers as only a narrow edge is presented which the workman is apt to take pains kto avoid especially as the upper surface is inclined'away from the connecting bridge, thereby making it more difficult to walk upon.

Having thus described my invention what f sheet metal, member including spaced legs and a connecting bight portion, the device adapted to straddlea floor sleeper with the bightportionlodged edgewise in a kerfl cut in the sleeper with the legs projecting laterally from the sides of the sleeper in a line with said kerf, the legs ybeing corrugated and each leg having a slot therein.

2. A device for anchoring ioor sleepers to a concrete slab, comprising a U-shaped sheet metal member including spaced legs and a connecting bight portion, the device adapted to straddle a iioor sleeper with the bight portion lodged edgewise in a kerf cut in the sleeper with the legs projecting laterally from the sides of the sleeper in a line with said lrerf, the legs being corrugated.

3. A device for anchoring floor sleepers to a concrete slab, comprising a U-sha'ped sheet metal member including spaced legs and a connecting bight portion, the legs and bight portion being. disposed in the same pla-ne and the device adaptedV to straddle the floor sleeper with the bight portion lodged edgewise in a kerf cut in the sleeper with-r the legs projecting laterally in alinement with the ends of the bight portion and in line with the said kerf. i

In testimony whereof, I sign this specification in the presence of two witnesses.
