- Be-it known that I, JULIUs R. lVnMLIN- a citizen of the United States. residing at; ooklyn, in the city of New Yonk, State and useful Improvements in Shoring, of which the following is a specification.

This .invention relates to shoring and especially to suchas is used for holding up the sides of ditches and-trenches.

The principal objects of my'invention are to 1gfirovide such' a shoring as will insure eat safety, byentirIy preventing the falling or caving in of the walls of an exaeration, and that will also have all the strength and rigidity required for the pur ase, With'the least possible weight; that can e readily and quiekl" applied and removed, and the vertical 's'e'c ons of which can be .My invention consists in the construction hereni'deseribed and set forth.,

The accompanying drawing illustrates one embodiment of my invention, in which,

the vertical members or sheets of the shoring; Fig. 2 is a similar View of two adjacent members in the. position they'will assn'ine in relation to each other when in view of one of. said members, but of a spective view of a part of a trench and my, improved shoring applied thereto, and also showing the method of'application;

Heretofore, in the digging of trenches'and ditches, the shoring or temporary support for the Walls of these excavations has been made of wooden planks, the planks being across the planks. the said Wales or rangers being in turn held in place by struts or braeesextending across the trench or to some bearing within the excavation. The

tidns or the shoring cannot be relied v upon for strength, as they are never of uniform strength, and they are'likely to have weak be the strongest. Mereover, in order to is necessary to give them considerable thick drive down into-the earth, es ecially when it: i hard, and the act of, timing often;

thermdre, these planks can be .used only two or three times at best, and they require so much bracing and the operation of driving them is so slow that the entire shoring operation by means of planks or boards is very expensive. If any of the planks break during the process of driving them into the earth, it renders them useless for the purpose intended.

My invention overcomes all the above dif ficulties; it provides vertical members for shoring that have the greatest strength and least weight and thickness, that can be readily driven with little power into the earth, that can be properly guided While being driven, so as to attain. their proper positions relatively to the trench'or excavation and their adjacent sections, that can be used "over and over again, and that can be readily removed as, soon as the retaining Wales or brasserie-removed. In the drawing, similar figures represent like parts. I

l is 'a vertical member 'or unit of my improved shoring, and, as shown, is provided Withlongitudinal projections and recesses 2 and 3, respectively. The particular form of the member or unit of my 35 shoring as shown in the drawing is that of "a corrugated or wavy sheet or plate of metal, this form being especially suitable for the purpose for 'which'it is intended,

as giving'the greatest strength and stiff ness with the least practicable weight and thickness,-and also as being thin enough, or sharp enough, at its edge'or point to be readily driven into the earth, and also as providing a number of vertically extending ridges and recesses that will register with corresponding recesses and ridges in the adjacent member and thereby permit the proper guiding of the same while it is being driven and aftenthe shoring is in position.

In addition to the vertical sections or members 1, the shoring consists of breastpieces, wales or rangers i eiztending longitudinally within the trench and transversely across and bearing against the vertical thembers 1, and struts or braces 5 with their ends bearing against the wales i so as to force tliefi'i against the members; 1: I

Fig. 1 illustrates my im roved shoring 110. as applied t6 tiiili, On Sia 6f the trench and shoring being broken away to more clearly show the construction and application, it being understood that, in this case,

there is another line of vertical members their ends.

The mode of application is as The trench is dug a few feet, 6 being the .wall. of the trench and 7 its bottom. The

wales or rangers 4 are then extended longitudinally with the trench bearing against the wall 6; then the struts or braces are applied between the two opposite wales with their ends bearing against the said wales. The members 1 are then driven between the wale and the adjacent wall down to the bottom 7 of the trench, the Wale 4 being a guide to the front of members 1 during said operation. The said members 1 are preferably driven one at a time, an edge or a longitudinal ridge of 1 one member being made to engage with a corresponding bend or recess of the contiguous member, so that the two will overlap and keep their proper positions relatively to each other.

In Fig. 4, it will be seen that six vertical members have been driven, as above stated, and for some distance below the bottom of the trench, and another member has been partly driven and is just about to be forced into the bottom of the trench. If vfor'any reason it be not desired to drive the members 1 into and below the bottom 7 of the trench, it may be necessary and expedient to have additional wales and struts at and near the bottom of the trench, to hold the lower portions of the members 1 against the wall 6.

In Fig. 2, the registering portions of the two contiguous members 1 are shown as overlapping a little more than any of the two adjacent sections in Fig. 4. When the sections are made with alternate ridges and recesses of similar size and similar distances apart, it is obvious that the two contiguous -S8CtlO11S or members 1 can be made to overpracticable and A may be made by denting the section as at 8 in Fig. 3. before the sections 1 are driven.

, This usually provides a. waterand quicksand-tight joint between the sections; but, if any leakage occurs, it is readily stopped by tightening the bracing and thus increasing the pressure of the wales. Inasmuch as the shoring is flexible and of double thickness only at theoverlapping joints the pressure of the wales is received mainly by the joints and a tight joint secured. This can follows not be accomplished with ordinary shoring or with the tongued and grooved planking frequently used.

After the trench or ditch has been dug down to the required depth and the work to be done completed, the excavation is usuall refilled andthe shoring is no longer needs It is obvious that, as soon as the wales and struts are removed, the sections -1 will fall apart and can be readily taken out and be ready for-re-shoring.

While I have described my method of shoring-as applied to a trench, it is evident that it is applicable to any kind of excavation with slight modifications. For instance, if the excavation is too large for the struts 5 to extend horizontally across, the said struts 5 are arranged to bear at one end against the wales 4 and at the other against the ground of the excavation itself or some other object.

I prefer to use corrugated sheet metal for thevertical sections 1 for the reasons above stated, and also for the reason that they can be obtained thus in an almost infinite-variety of widths andthicknesses, and because of the great facility of procuring such forms.

I am aware-that corrugated sheets and other stifi'ened plates have been used for roofing and for sheet-piling, but such sheets were secured together by either nails or other fastening's. This construction is not 'appropriateffor temporary shoring .of vertical walls of earth, as it would beexceedingly difiicult, if not imp ossible,.to separate the plates if used as vertical ,sections after they have been so secured and driven into the earth. Moreover, such constructionhas never been used for the purpose of this invention, and could not separate or drop apart and be readily removed in the-same manner asfmy improved shoring. I do not limit myself to the recise construction above described an shown, as many changesmay be made therein without departing from the spirit of my invention or sacrificing its chief advantages.

What I claim as new and desire to secure by Letters Patent, is: l

1. A wall shoring comprising a plurality of independent sheet metal sections, having curved adjacent edges, and with the edge of one section engaging, but not locking with, the curve of the adjacent section, a removable bar or vwale extending transversely across said sections and a strut bearing against said bar or wale.

2. A wall .shoring comprising a plurality of independent corrugated sections, and with a longitudinal ridge of one section engaging with a corresponding recess of an adjacente ex section, and a removable bar'or wa tending transversely across said sections.

3. A wall shoring-comprising a plurality of independent corrugated sections, and with.

evaees against said-bar or wale. I 4. A metallic shoring comprlsing series of. independent longitudinal corrugated plates adapted to supporta' bank ofearth' or similar material with their adjacent edges laterally overlapping to the extent of at least a. part of one corrugation, in combination Wlth waling pieces arranged against the free surface of said piling, and supporting means abutting said 'waling pieces for holding same and the piling in 'position.

,5. A'wall shorin comprising a series of independent vertica ly arranged, corrugated plates, assembled with their adjacent edges in lateral contact and overlapping: the exposed surfaces ofsaid plates lasing supported y transverse waling pieces and struts, to form substantially water-tight joints and permit the ready disengagement of said plates when-the supports are removed.

6. A wall shoring com rising a series of longitudinally coilfilgate metal plates,each having means on one of its lateral edges for forcing a driven late into close contact with an adjacent p ate, and means for supporting the exposed surface of said plates.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing Witnesses, this 21st day of September 1907.v
