Application filed September 3, 1927. Serial'No. 217,480.

This invention relates to geometrical instruments and its general object 1s to provide an adjustable roof and truss framing gage tool, for obtaining lengths and cuts of common rafters, hips, valleys, jack rafters, ties, brace lengths and cuts, hips and jacks for skylights in sheet metal work and all truss `members instructural iron work, as well as all other truss members and the like such as knee braces, internal braces, top cords and struts, in an easy, accurate and inexpensive manner and with very little effort.

A further object of theinvention is to provide a gagetool of the character above set forth, thatissimple in construct-ion', inexpensive to manufacture, and includes Aa number of rules cooperatively associated for determining the length and cuts of the members referred to and in a manner whereby the rules can be easily moved with respect to each other and retained in any desired setposition.

Another object of the invention is to provide a gage tool which includes a number of rules provided with novel means for securing l the same together for cooperative association. This invention 'also consists in certain other features of construction and in the combina.- tion and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing our invention in detail, reference will be had to the accompanying drawings wherein Vlike characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a top plan view of the tool forming the subject matter of the present invention.

Figure 2 is an edge elevation thereof.

Figure 3 is a sectional view taken on line 3-3 of Figure 1 looking in the direction of ,the arrows.

Figure 4 is a sectional view taken o-n line 4 4 of Figure 1 the arrows.

Figure 5 is a perspective view of the sliding block which is secured to the jack rule for mounting the same for slidable movement on `the run rule. v f

Figure 6 is a similar'view of the run and rise rule slidingy blocks or tongues. n

Referring to the drawings in detail, the refd erenc'e' numeral 1 indicates the vertical or rise rule which is provided. with a geneve 2 and looking'in the direction of h as its upper end arranged in curved formation as at 3 with a shoulder 4 disposed at the puncture of the curved portion with the body of the rule, as best shown in Figure 1 of the drawings. o

` `Hingedly secured to the rise rule adjacent its upperend and on theedge opposite the curved portion isa hypotenuse rule 5 which hascounter-sunk in its edge opposed to its hinged edge, one end portion of a strip 6. The strip k6 is curved from its secured end portion in a manner tol follow the curvature of the curved portion 3 and is adapted tobe disposed in contacting engagement therewith. The curved portion of the strip is provided with a longitudinally disposed slot 7 vthrough which is arranged a. screw 8 having wood threads on one portion for securing the same' in the end of the riserule adjacent one edge as shown, and lthe remaining portion of thev screw 8 is provided with machine threads to accommodate a'nut 9. By this arrangement, it will be obvious that the hypotenuse rule is hingedly secured to the rise rulefand can be disposed at any desired angle within the range of the slot 7 and secured at said angle through the medium of the nut 9. The curved portion has arranged on one of its faces degree graduations which are indicated by the `reference numeral 10. y

The-rise rule has secured to its endoppoy site the curved portion` a straight stripll which has one end extending beyond the inner edge ofthe rise rule'and terminates in a curved spring finger 12 adapted to vbe received in a recess 13 formed in the adiacent end of the hypotenuse rule for securing the latterin cont-acting engagement with the rise rulev as will be apparent.I I v f Mounted for slidable movement with re` spect to the rise rule is a run rule 14 which is `provided with a groove 15 longitudinally disposed therein forv the greatest portion of its length, and which terminates adjacent one end while its oppositeend is disposed in com- Vmunication with a slot 16 extending the re-v maininof distance of the run rule as best shown in Figliie 1 of the drawings.l

In Figurer` I have shown the means for slidably securing the run rule to the rise rule and for moving the' run rule.transversely.r

thereof, and thisl means includes an elongated hollow member 17 square in cross section, which has extending laterally therefrom a 11u substantiallytriangularly shaped projection is having termed therewith ene portion of a a the `groove 2 and slot 1G.

block member 19, whi'ie theremaining portion of said blofl; member extends from the opposite side of said member 17 as shown. The block member 19 has, projecting from its desired -and 'retained `in their #respective adusted positions.

The tool is extremely useful for obtaining the lengths and cuts of root members andv lends, ears 2O arranged in spaced parallely bracing means 'therefor and the operation pairs and adapted to slidably receive one of the portions adjacent the slot 16 in the run rule 14, as shown in `Figure y1 ofthe drawings. When in this position, the member 17 is disposed in the groove 2 ot'rthe rise rule, .andthe member 17 and block 19 are each vv'provided withspring'fingers indicated respectively by the reference numerals c,2l-and 22 for engagement with one ot the lwalls of One of theends lof theblock 19 is provided with asquare opening adapted to reeeiveandito .be sevcured therein the square end.v of a screw 24 :which threadedly receives a serrated nut 25 mounted-in a bracket 26 secured to the slotted 'end ofthe run. rule. The bracket is provided `withzan opening to allow `for the passage of .the screw 2Ll--and upon rotating the nut.25,`it will :be apparent that the `run rule will be capable of being-'moved approximately the lengthfof the screw 24, and transversely A,of

the rise ruie. The run rule is urthersecured #tothe rise. rule and 1s movable longitudinally ithereof'due tothe yarrangement of the block 1 `=member ltin'the groove2.

The vjack rule which is Vindicated bythe reference numeral :27 is rprovided with a revcess 28 vadjacent one end to slidably receive yithe'run rule and secu ed to the jack rule in therecessx28fthereoftirough the medium of screws 29 is a block 30 which is provided with Aspringfinger-s 31 arrangedto engage oneot' kt'hefwalls of the `groove 15 of the run rule as best shown in Figure 1.. This arrangement allows thejack rule to be Asli'dably `mounted xon the run rule, and to be positioneditoward and away `trom the-frise rule as-will beap- `parent.` yThe run rule and jack rule are disposed to overliethe'rise rule and. hypotenuse rule, and ity will ,benotedthatthe run rule isfprovided'with a bevelededge 32 andthe jack 'rule is also provided with :a beveled edge 33 disposed' in confronting relation with -the'inn'eredge of. the rise rule.

Each of the' rules are :graduated Vorlaidl ott to a. foot scale, and these graduations are disposed uponthe beveled edges v32 and 33 'of theki run lrulev andjack rule, while' the rise rule l and 'hypotenuse rule' have their; gra'duations 'disposed adjacenttheir confrontingsedges. The'j ack rule .is further` provided :with jack spaces 34 arranged `for sixteen inch, Ieigfl'iteen finchlaznd'twentysfour inch spaces.l i

` From `the above description and fdisclosnre ofthe drawings, it will be obviousxthat-we "have-provided lan adjustable roof landzftriiss l:framing .gage tool including a plurality. of

'cooperatively associated' rules securedto :and

- arranged withrespect'to each other in fa'y manner '.Whereby theyffcan be easily :adjusted as Ithereoil for obtaining the lengths and cuts oil a common ratter may be brieiiy described as follows:

Considering that the roof is nine feet rise andthirteen feet run, and with all raft-ers set .at `sixteen .inches center ato reenter, place Athe `run rule as shown in Figurel ofthedrawings, move the run rule onrise rule, so that graduation'9 on'i'ise rule intersects with'thefzero fof iiiirriile, which is the rise, then move tthe `hypotenuserule to thirteen on run rulewhieh is therun, and.` at theinterseetionof therun rule and hypotenuse Irule the vlength of the ratter can be ascertained. For ysteelfsquare marking of rafters use;nine for riseicut, and thirteen oivrun cutias-shown on rise rule; and runv rule, which are the cuts for common rafters. Forgetting cutswith ordinary@ carpen-ter bevel square, v )lace heel o-l bevel square on .hypotenuse "rule and `blade fagainst .run rule, this will give bottomcut of'rattefr and i'er top eut of ratter piitheel on bevelfagainst the hypotenuserule, and bladeg-againstrthe rise rule. lBy the use of theftoh'the'lengths Aand .cuts are extremely accurate, and it ,will be apparent that lwhile we have illustrated the application oiE the'toolitor commonznafters, it can be used `with as much simplicity with hips,fvalleys,fjack rafters aand other members.

It is'thou'ght from theforegoing desc-rip- ,tion that the advantages land'novelr features ot' our invention .will be' readilyv apparent.
