SQUARE.

Specification of Letters Patent.

Patented Dec. 24, 1912.

Application filed June 27, 1911. Serial No. 635,660.

To all whom it may concern:

Be it known that I, CARLTON E. IVIISIILER, citizen of the United States, residing at Shipshewana, in the county of Lagrange and State of Indiana, have invented certain new and useful Improvements in Squares, of which the following is a specification.

This invention relates to framing squares.

The object of the present invention is to provide a square particularly adapted for use by carpenters and others in the formation of mortises, the invention embodying such characteristics that the marking or mapping out of the mortise and the formation of pin holes for cooperation with the mortise joint may be greatly facilitated.

\Vith the above and other objects in view, the invention consists in the construction and novel combination of parts hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claims; it being understood that various changes in the form, proportion, size and minor details, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings :Figure 1 is a plan view of the invention. Fig. 2 is an end view of the invention. Fig. 3 is a perspective view of the invention applied to a piece of timber to illustrate the purpose of the invention.

Referring now more particularly to the accompanying drawings, the reference character 4 indicates a piece of timber illustrating where a mortise 5 has been formed in the face side of the timber and in Fig. 3 showing the square A applied to the timber for the purpose of forming another mortise.

The reference characters 6 and 7 respectively indicate parallel inner and outer ruling members which may be of the same length, or one, preferably the inner one, shorter than the outer ruling member. In any event, the ruling members are connected at one end by the transverse ruling member 8, the ruling members 6 and 7, while parallel, being preferably arranged in different planes so that when the ruling member 6 is disposed on the upper face side of the timher 4, the ruling member 7 may present its inner edge to the sideface of the timber t, as clearly shown in Fig. 3.

To provide for the above disposition of the ruling members 6 and 7 with relation to each other and the timber, the inner end of the transverse ruling member 8 is preferably bent at an angle to its body portion as indicated at 9 for the purpose of forming a joint for substantially snug engagementwith the right-angled faces of the timber and in this respect cooperate with the web 10 which connects the inner and outer ruling members 6 and 7 and which web is bentto provide for a snug joint with the rightaugled disposition of the upper and side faces of the timber.

The space between the ruling

members

6, 7 and 8 and the web provides an opening 11 which constitutes a band opening and by which the square may be readily suspended from a hook (not shown), if desired.

In the use of the invention the instrument is placed on a piece of timber so that the carpenter or manipulator may indicate the side lines 0 according to measurement for a mortise by marking along opposite edges of the inner ruling member 6. The end lines of the mortise are made along the connecting ruling member 8, the square being shifted, on the timber for such purpose. Of course, the end lines for the mortise may be made in any other manner and it is also obvious that the instrument may be so placed that one of the end lines for the m0rtise may be made along the outer edge of the ruling member 8 without necessarily shifting the instrument. At the time of indicating the side lines for the mortise it is preferable to indicate the point for the pin holes 12. For this purpose the outer ruling member 7 is graduated and used for measurements or for marking or for both in order to accurately locate the point for boring the hole 12 for the dowel or other pin (not shown) which passes through the hole 12 and into the tenon or other piece of material which is fitted in the mortise 5.

It will be noted that all three ruling members have their flat faces disposed in the same direction, by virtue of which, and the graduations on the ruling members, the measurements may be made by the carpenter or other manipulator without the neces sity of changing position, the graduations all being in View at the same time by a look in substantially the same direction by the manipulator.

What is claimed is l. A square of the character described comprising inner and outer graduated ruling members, another graduated ruling member disposed at the ends of the aforesaid graduated ruling members and at a right angle to the latter and connecting adjacent ends of the latter, the connecting graduated ruling member being bent intermediate the inner and outer graduated ruling members to dispose the outer graduated ruling member in a different but parallel plane with the plane of the inner graduated ruling member, and a Web connecting the inner and outer graduated ruling members bent intermediate its end to correspond with the bend in said connecting graduated rul ing member and in spaced relation to the latter to provide an opening by which the rule may be carried or supported, the inner graduated ruling member being spaced from the outer graduated ruling member a distance substantially half the length of the bent portion of the third mentioned graduated ruling member and the bent Web, whereby measurements and rulings may be made on one face of a piece of material between opposite edges of the material and along both sides of the inner graduated ruling member.

2. A square or" the character described comprising inner and outer graduated ruling members, another graduated ruling member connecting adjacent ends of the inner and outer graduated ruling members, the connecting graduated ruling member between the inner and outer graduated ruling members being bent at a right angle, and a web connect-ing the inner and outer graduated ruling members in spaced relation to the connecting graduated ruling member and intermediate its ends bent at a rightangle, the bent web and the bent graduated ruling member disposing the inner and outer graduated ruling members in difi'erent parallel planes so that measurements and rulings may be made on one face of a piece of material between opposite edges of the material. and along both sides of the inner graduated ruling member and measurements and rulings made on another face of the same material Without removing the inner and outer graduated ruling member from the material.

In testimony whereof I aflix my signature in presence of two witnesses.
