CARPENTERS SCRIBEB.

Application filed January 5, 1923.

To cZZwZmm iii-mayconcern.-

Be it known that LTHOMAS H. KING, a c"iZe'n or the United States residing at Charlotte, in the county of ldecklenburg and Sit-ate of North Carolina, have invented new and useful Improvements in Carpenters Scribers, ot which the following is a specification.

The object oi this invention is to produce a scribe --'l or carpenters use which will materially facilitate the accurate cutting of boards or timbers that are designed to have their ends in contacting engagement with upri .ts or other timbers.

'ihe drawings which, accompany and rm part of this application illustrate a satisfactory eml'iodiment of the improve ment reduced to practice, and wherein Figure 1. is a view illustrating the manner in which the tool is employed for scribing siding boards so that the same will accurately engage the corner post of a building.

Figure 2 is a view showing the manner in which the device is employed for scribin a base board with respect to the vertica stile of a door casing.

Figure 3 is a view showing the manner in which the tool is employed for scribing the upper board of a door casing so that the same will accurately engage the mitered upper edge of the vertical board or stile ot' the casing.

Figure 4 is a perspective view of the tool.

Figure 5 is an approximately central vertical longitudinal sectional View therethrough Figure 6 is a sectional View on the line 6-6 of Figure 5.

Remaining views illustrate details.

In frame building constructions the outer or siding boards 1 are designed to be cut transversely so that the ends thereof will snugly tit against the corner board As the siding boards are necessarily of a length greater than the distance between the corner boards 2, precision in cutting the boards in order that a tight joint may be made between the sidings and the corner posts, is an absolute necessity. The siding boards are arranged in lapping relation and therefore an ordinary rule or square cannot be successfully used in scribing theboards. In carrying out my invention, I malre use Of a tool that includes parallel arms, and which arms are connccted at one of their ends by what 1 will term a head. Each armincludes an inner member 3 which has its sides beveled inwardly from its outer i e to a suitable away fr inner tace, and

st ted c numeral I) the n ace provided with receive the tongue ns 7 is provided 5 o contact with members 3,

ing its i ner i a CiOVG-tztl-lQCl groove 6 to Suitable binding inea upon the outer m mber c the tongues -l of the inner whereby the outer members may be sustained adjusted on' the inner members. Each inne i nber or arm has one oi itsends both thickened and widened to provide shoulders 8 net which the s'lidable members 5 aout ween the same are moved thereagainst. The nds of the arms just referred to, indicated for distinction by the numeral 9, each l'iave a squared opening 10 therethrough and is further provided -with a threaded opening through which a binding screw 11 'i'iitSSi-ES, the said screw entering the opening 10 to engage a bloci: 12 that is received through the openings and that passes through sonared opening i3 in the block sectiois 14-, that head. desired number ill constitute the of block sections are cinployeth whereby the arms of the tool are sustained at determined spaced relationsso that the siding or other boards of dillerent thicknesses may be received between the arms.

The thicker block 14; has its opposed faces provided with projecting lugs 15 that are designed to be received in openings 16 on the inner faces of the narrower blocks, when the latter are employed the outer of the narrower blocks being provided with lugs 1'7, and these lugs well as the projecting lugs on the first mentioned block are designed to be received in openings 18 on the inner faces of the arm sections 3. In this manner. a tight joint is at all times sustained bet icon the head sections and the arms.

()n one of the outer. sections 5 of one of the arms there is a projecting lug 19 having a dove-tailed opening therethrough to receive a cross sectionally dove-tailed shaped rule 20, suitable binding means 21 passing through the lug d contacting the rule. The rule orovides the device with a gauge wherebv the lap of the siding boards can be accurately arranged. To accomplish this, the lug is positioned beneath a siding that is already secured, andv the rule is adjusted so that the same will contact with the lower edge of the siding board about to be secured. 7

To allow the siding boards to be properly scribed, the head sections of the improvement are adjusted so that the siding boards of determined thicknesses will be properly received between the arms thereof, and

;the tool is thus arranged on the board and is brought so that'one of its edges will contact with the inner edge of the corner board 2, when a scribe line is marked on the board to be cut. In this manner, an accurate out can be made so that a tight joint will be established between the siding andthe corner boards. i

As disclosed in Figure 2 of the drawings,

the tool can be successfully used for producing an accurate joint between a'base board and the vertical stile of a' door frame. Also, as disclosed in Figure 3, the upper board of the door frame can be properly scribed to'fit the mitercut at the upper end of the vertical stile. This allows a great saving of the carpenters time, inasmuch as mitered joints produced in the usual man-- ner require planing by what is termed a block plane before an accurate fit is obtained between the'joi-nts. It is thought that the foregoing description, when taken in connection with the drawings will fully set forth the construction, operation and ad vantages of the improvement, it being, of course, understood that the tool is susceptr ble to other uses than those herein described, and further that I am not to be restricted to the precise structural details herein a1- luded to, but may make such changes therefrom as fall Within the scope of what I claim.

Having described the invention, I claim 1. A carpenters tool, for the purpose set forth, comprising a head made up of a plurality of superimposed blocks, interengaging means between the contacting faces of the blocks, an element passing centrally through the blocks, two parallel arms extending inQthe' same direction away from the ends of the blocks and receiving the element 'therethrough at'opposite ends of the block, respectively, binding means between each arm and the element, interengaging block, each "of said arms comprising an inner member secured to said element and having a dove-tailed tongue and an outer member having a dove-tailed groove to slidably receive the tongue, and binding means between the outer and inner members of the arms.

V 2. A carpenters tool, for :the purpose set forth, comprising a head made up of a plurality ofsuperimpcsed blocks, ,int'erengaging means between the contacting faces of V the blocks, an element passing centrallyl through the blocks, parallel arms extending in the same direction from the head, each receiving the element therethrough, binding a ture. r I THOMAS H.
