W. H. SHEPPARD. GEOLOGICAL FAULT GUIDE. APPLICATION FILED JULY 9,1919.

2 SHEETS-SHEET I- w'. H. SHEPPARD, GEOLOGICAL FAULT GUIDE. APPLICATION FILED JULY 9, I919.

' Patented Aug. 15, 1922.

2 SHEETS-SHEET 2.

To all whom it may wmm= Be a known that I, im a a-H. sass;

rARD, 'a citizen of the United States, 'r'esid mg in the cityand county of San Francisco,

in the State of California, have invented certain new, and useful Improvements 1n Geological-Fault Guides, whereof the foli lowing is a specificationl This invention relates guides. I V

The invention is intended to facilitatethe study of geologicand mineral formations, and to indicate, especially to the miner, the probable course of veins and'o ther formations. To this end the "inventionconsists in a series of blocks,' which in normal juxtaposition fmay constitute a rectangle, or other figure. These blocks are separated byplanes which may represent cleavage or fault planes, the block in its entirety representing the country rock of a district.- on the surface of the block may be marked the strata of the district, preferably as it would appear before displacement, and any veins that may require study. i

The combined block thus represents a section of countr and by sliding the sub-mem-' bers upon eac other, will indicate the probable course of the formation to be studied.

To illustrate my invention I have selected the device illustrated in the accompanying two sheets of drawings, the same consisting of a rectangular block divided into 'five submembers, by planes as will be set forth hereinafter. The figures of the drawing are as follows:- I

Figure 1 is a perspective view of the rectangular compound block, composed of the five sub-members, and having marked thereon the normal strata, and a vein.

Figure 2 is a perspective view of the same after a distortion, in which only one submember is shifted.

Figure 3 is the same again, after a greater distortion, in which all the sub-members are shigted.

re 4 is a perspective view showing two only of the sub-members, the others being omitted for clearness of view, both of the sub-members shown being displaced, one of them being turned almost at right angles to its normal position.

Fi 'ure 5 shows the two larger sub-memhers butt to butt, the others being omitted.

fourth sub-"members;

to geological-fault p d-"to th rmembers" 5, constitute a wed aibt which member 5 is the edge. -Member 5, is a five sided solid, of which two sides are parallel and of triangular shape, and the other three enor osican-raunr Qu nn." I

Patentedihug."

) Figure 6 fshows the two larger fs'ub-meni bers in normal position, the" others beingv omitted.

I In the drawings :.-A is the ot ir'npoiindrec tangular block,' ma de upfof thesub-members 1, 2," 3,4,5. The member 1' isa quasip-arela lelopipedicah solid, wliose cross-section" in 'one"direction is ajt ."apijezoid.; Themejm'ber 1 'iscut ofl, making ita' SBVQIisided solid hav} j mg two pairs of opposed parallel si desfwith p-airs,,and l the othertwo: sides forming. anob'tuse wedge.

2 is 1 similar to member 1 but its acute angle one sidev atright'anglest a. both Members 3 'and4 are both six'side'di solids sides disposed about the same.

Upon the compound block, thus constituted, may be markedthe course of the-nor; mal' strata, as indicated by the dotted lines 41,04. In practice these strata may be marked by colored streaks or the block may be built of actual layers. The block may also have marked thereon avein b, ora number of veins may be marked thereon I have" marked but one, for the sake of simplicity.

In use, the-compound block A being marked as indicated to show the normal strata, and with a vein I), which in this case 1 may indicate a surface vein,;may rest nor mally upon a table. The block being tilted,.: say to the left, will assume the position shown in Figure 3, exhibliting a main iffaultf and local faults, and the displacement ofthe vein, and the user will see from the device what course he should follow to" find his vein,jif he loses it because offault. in the 'particularinstance selected for illustration,

member 1 will show the footwall'of the fault, and member, 2 the. hanging-wall of the i ig re 7 '1 shows the t me as uiiai aa fault, whilst members 3, 4., and 5-showthe shears.

Figure 8 developed by the "displacement,

would naturally be'filledby infiltration or 1 otherwise, and would constitute lenses of ore, whose location would be indicated by I The open spaescfd, 0-, shown in the block, and could be sought for accordin 1y. v

a-ving thus described my invention, and an embodiment of it, in the full-{clear and 5 exact terms required by law, and knowingthat it comprises novel, useful and valuable improvements in the art to which it pertains, I here state that I do not wish to be limited to the precise construction and arrangement of the several parts, as herein set forth,as the same maybe variously modified by a skilled mechanic without departing from the spirit of the invention. p

What I claim and desire to secure by Letters-Patent of the United States, is the following, towit:

1. A device of the character described, comprising a, block adapted to represent fault planes in geologicalformations, s'a'ld 20151061; being divided into a plurality o-f 2. A'device of the character described, comprising a block adapted to I represent fault planes in geological formations, Sfitld' oblique angled sub-members. I

block being divided into a plurality of sec- .tions having each a different shape fitted together.

3. A device of the v character described, comprising a block, adapted to represent fault planes in geological formations, said block being sub-divided into a plurality of respond with the shifted strata of the country represented will indicate the shifted position of the vein or other formatio 'i.

6. A device of the, character described, comprising a series of oblique-angledsubmembers, fitted together on plane surfaces,

and adapted to be shifted with referenceto each other upon said plane s'urface'. In testimony that 1 claim the foregoing I have hereto set my hand this 21st day WILLIAM H. SHEP RD) Witnesses FLORENCE L. 011512,
