Applicationled June9,1906 Serial NO- 32919521' To @ZZ whom,v it may concern,.-

Be it known that I, WILLIAM E. THORNE, a citizen o f the United States, residing at 1115Detroit street, in the'city of Denver,

county of Denver, and State of Colorado, have invented certain new and useful Imrovements in Revetments, of which the folowing is a specication.

My inventionvrelates to improvements in the construction of revetments--or ri rap- Work of any sort. It consists, essential y, of

the use'of a woven-.Wire base and cover appropriately secured, the stone or material used'being laid between. It has been found 'that it is diiiicult-to lay up loose" stone to form a revetment without supporting or binding the stone into place in some manner; but the methods heretofore in use have not resulted satisfactorily. This is especially true where the revetment is made upon a sloping embankment. The advantages of my improvement will hereinafter be specifically pointed out. l In the accompanying drawings, Figure 1 is a pers ective view shQwing a transverse section o a revetment constructed upon a slope for the purpose of retaining the water and of preventing the same from Wearingiaway the Fig. 2 shows a vertical crosssection of a damconstructed in my improved manner:- Fig. 3 shows a Wall made up of successive'layers of stone, a sheet of woven `wire being laced between each two laye-rs thereof, the inding-wires passing outwardly from one sheet to another.

In the drawings, 1 isthe embankment in transverse section.

9 indicates the surface of the embankment above the revetment.

2 is the foundation or base, of'woven wire, which is laid upon the ground Ain beginning the construction of a revetment in my. im-

proved. manner. The meshes of the Wire may be of any desired size or weight, -and the wire is iirmly bound and strengthened along its edges. After this foundation-wire is laid wires (indicated at 3) are secured to the foundation-wire.'4 'lhese wires 3 are intended to act as tie or binding Wires in the manner hereinafter shown. The binding-wires 3 are arrangec' in staggered series `at intervals, whichwill be determined by the size of the stone used. A section of the stone wall, as indicated at 4, is then laid up. When the desired height is reached, a cover or top section ceeds as a ove stated.

of wire 5 is laid'upon the wall, and the binding-Wires 3 being irmly secured tothe b ottom-or foundation-.Wire 2 at 8 are carried through the meshes of thetop section 5 and twisted together, as indicated at 6. In this manner is -formed a basketor binding-support for the loose stonework composed of a foundation-section, tie-Wires secured thereto- 'and extended at a right angleoutwardly therefroml in a .staggered series at intervals determined by the size of the stone used, these tie-wires extending upward through the layers of stone andhaving their upper ends free above the top of the Wall.' A coversheet ofwire is then laid on'and thel tie-wires are passed through the same and twisted,A tightly 'to secure their upper ends in the cover-section of wire.' It is apparent -that the wall laid up in this manner is very solid -I and substantial-and bound'together in such manner that the stone cannot fall apart. If in time the wire rusts and breaks, it will be found-that the Wall has settled and the parts have become so closely united that the wall will still remain intact. Further, a wall constructed in this manner is bound together throughout and forms a continuous vstrucel ture, one part'depending'upon another, a result which would not be possibleif only loose stone were used without the bindingsheets and ties of wire to consolidate the whole into one structure.

It is seen that this ,construction is of use in building dams also, and I have shown a dam in section in Fig. 2. 10 designates -anchor boulders o1; stones, to which are secured the binding-Wires 11. As the successive upper layers of stone are placed the Wires 11 are brought-out until the dam has the height de- 4 sired, whereupon a cover-sheetof Woven wire12 is laid overthe whole and r'lnly secured in place by the' binding-wires 11, In the construction of dams-loose stones 13 are dropped into the stream until. the stone reaches' a height slightly above the surface of the Water.4 The anchor boulders or stones are then laced, and the construction pro-` In this construction the base or lower sheet of woven Wire is not employed. It is apparent, however, that it may bc utilized in the place of the' anchoraboulders, if desired.

The construction herein shown is believed to be new and has been demonstrated to be a very substantial improvement 1n the con- IOO IIC

' of dams.

een be practiced by one person alone end 1s struction of riprep or e revetment of any kind end has the advantage ofbeing not only durable, but renders it possible to use loose stone for revetment purposes where it would be impossible to do so if the methods now in use would'heve to be resorted to. Where the water covers the stone, loose materiel, such es hay or straw, muy be used for pack-- ing, und thereby the siltwill be retained, which will make the well more compact. However, it is to be understood that i do not use wire e .temporary expedient, for it is shown that the wire has wearing qualities, and it serves to bind together the lstone structure for u long period of time.

The well me y be leid up in successive layers of stone with the foundation-sheet of woven wire et the bottom, und e cover-sheet maybe used with euch layer. The binding-wires muy be brought throu h from thebottom sheet and secured in esc of the upper sheets as they ere laid on. ln this manner thewell muy be formed more comp actly und securely.

The binding-wires are preferably formed with double or treble strands, and in securing thev seine to the successive sheets of woven wire they may be straddled through the meshes, and thus furnish e 'firmer engagement.

My improved construction of revetments is simple'end een be readily utilized by lendowners and others interested in the preservetion of the banks of streams or the formation It is seen also that the invention durable and admits of .quick repair when needed.

sensei What I claim as new, and desire to secure by Letters Patent, is-

1. A revetment, dem, or the like, comprising e vmess of disposed parts, e flexible covering for said mess, end Ineens for securing seid covering to oints below the surface ol' said mess, wherey seid loosely-disposed parts are bound together.

x2. A revetment, dem, or the like, compris-- ing a mess of material composed of looselydisposed `erts, e flexible coverin `forl said- -mess, bin ing-wires secured tosai covering and penetrating seid mess and secured 'at points below the surface of said mass. 8. A revetment, dem, or the like, comprising e mess of material composed of. looselydisposed parts, en upper stretumoflexible materiel constituting e 'covering for seid mess, e substretum of'fiexible' material, and binding means secured to said substretum and brought outwardly through seid. massend secured to seid upper stratum.

4. A revetment composed 'of e foundation of wire mesh, loose stone leid thereon, a cover of wire mesh upon seid stone, arid tiewiresl secured to seit foundation wire mesh and assed upwardly through said stone and lirmy secured to seid cover of wire mesh, whereby the stones ere rmly bound and secured in place.

in testimony whereof l affix my signature inthe presence of two witnesses. I
