CARPENTEBS BEVEL.

Application filed July 26,

To all iv/20m it may concern:

Be itknown that I, OTIS EAST; a citizen of the -Ulrited states, and a resident oi. Hastings-upon-l-Iudson, county of lVe'stchester, and-State of New York; United States of America, have invented certain new and use ful Improvements in Garpenters- Bevels. of which the-following is a specification.

This invention relates-t carpenters tools and particularly to tools ofthe type known as bevels or bevel squares.

One object of the invention is to provide a tool of the-character described having adjnstable blades at both ends of the tool thereby increasing the utility thereot;

Another object ofthe invention .is to provide a tool so constructed that a blade atone endof the handle can be set at one definite angle and the blade at the opposite end can be set at another definite or pretermined angle.

Further objects of the invention will ap pear from the following description taken in connection with the drawings which form a part of this applicationand in which,

The invention briefly described. consists of atool comprising a lifandle having a pair of separate side members and a plurality of blades pivotally and slidably mounted 1923: Serial 'No. 653,63l.

on pins disposed.adjacentthe ends otthc handle. Certain of the blades are adjustable to predetermined angles with respect to-the handle and in the particular embodiments of the inventionshown theside members of the handle havemeans such as shoulders formed-thereon for positioning the blades at'such predetermined:angles, these slroulders forming stops. By providing adj ustable blades at both ends of the handle the utility of the tool is increased since a blade at one end may be set atone angle and the blade at the other end may beset'ntedifleren-t angle.- Further details of the invention will appear from the following. descrip-tion.

Referring first to the embodiment of the invention shown in Figs. 1-10 inclusive, the handle of the tool comprises side members and 21 which are disposed in spaced relation with respect to each other and-are con nected by means. of

pins

22 and 23, eaclrpin having a head 24 at one end thereot and a squared portion adjacent the head and received :in asquare hole 26 in the side member 211 (Fig, 7). Eachpin has threadedon its opposite end a thumb nut 26 for clamping tthe blades in adjustedposition between t he side mem bers of the handle.

Each pin has pivotally ar dslidablr mounted thereon a plurality ol blades and in the embodiment shown in Figs. 1 10, blades .r and Bareniounted on pin andbladcs (l and D=aremounted on pin 22. Each of these blades has alongitudinal slot 30 therein thepins being disposed in the slots of theb'lades. The blades are also beveledat their free ends asshown at 31. The side member 20 of theliandle has a-shonlder 32 (Fig; against which the be eled endill of the blade D seats when this blade is in foldedposition. The side member 214m" the handle has a shoulder 33 against which the end l of the blade- A seatswhen this blade is in folded position.

Means is provided on the side member 2) for positioningthe blade B at right angles tothe handle and this means consists of a beveled shoulder adapted to. engage a beveled'edgc portion 3601* the blade B when this blade is swung to a. position at right al'lgles to the handle.

Means is also provided on the side member 21 for positioning the blade; C at; an angle of degrees withrespect to the handie. This means consists.- of a beveled shoulder 37 engageable by a beveled edge 38 of the blade C when this blade is swung to an angle of 45 degrees with respect to the handle. The beveled ends 31 of the blades B and C engage respectively the

pins

22 and 23 when these blades are in folded osition.

lVith the form of the invention shown in Figs. 1-10 inclusive and just described, the blades A and maybe swung to any desired angle with respect to the handle or these blades may be retained in folded position and the blades B and C may be swung respectively to angles of 90 degrees and 45 degrees with respect to the handle. The blades may be clamped in any desired degree of adjustment by means of the thumb nuts 26*.

In Figs. 11 and 12 the blade B is swung to a position at 90 degrees with reference to the handle and the beveled edge 36 of this blade engages the beveled shoulder formed on the side member 20.

Alsoin these figures the blade C is swung to a position at 90 degrees to the handle and the beveled edge 38 of this blade engages the beveled shoulder 37 formed on the side member 21 of the handle. The blades A and D are in folded position and the thumb nuts 26 are turned until the blades B and C are firmly clamped between the

side members

20 and 21 and are thereby retained in adjusted position.

A simpler form of the invention is illustrated in Figs. 13 and 14 inclusive, and in these figures one blade is mounted on each end of the device. The handle in this embodiment comprises side members 40 and 41 v connected by

pins

42 and 43 having heads 44 and squared portions 45 received by square openings in the side member 41. Thumb nuts 46 are threaded on the

pins

42 and 43. A blade E is pivotally and slidably mounted on the pin 42 and the blade F is similarly mounted on the pin 43. These blades are beveled as shown at 47 at their free ends. The beveled end of the blade F seats against a shoulder 48 formed on the side member 40 and the beveled end of the blade E seats against a shoulder 49 formed on the member 41, The blades E and F may be swung to any desired angle with respect to the handle and may be clamped in adjusted .position by means of the thumb nuts 46.

Although certain specific embodiments of the invention have been particularly illustrated and described, it will be understood that the invention is capable of modification and that further changes in the construction and in the arrangement of the various cooperating parts may be madewithout departing from the spirit or scope of the invention as expressed in the following claims.

What I claim is v 1. A tool comprising. a pair of side mem bers disposed in spaced relation, pins connecting said members and located adjacent the ends thereof, an adjustable blade mounted on each pin and foldable between the side members, and raised means of the thickness of the adjacent blade on said side members forming stops for limiting the pivotal move-- ment of another of said blades and positioning said other blades at predetermined angles with respect to the side members.

2. A tool comprising a pair of side members disposed in spaced relation, pins connecting said members and located adjacent the ends thereof. a slotted, adjustable blade mounted. on each pin and fold-able between the side members, and shoulders on said side members forming stops for limiting the pivotal movement of another of said blades and positioning said other blades at predeterjonined angles with respect to the side memers.

3. A tool comprising a pair of side members disposed in spaced relation, pins connecting said members and located adjacent the ends thereof, an adjustable blade mounted on each pin a shoulder on each side member raised to the thickness of the adjacent lade and means on said pins for clamping the blades in adjusted position.

4. A tool comprising a pair of side members disposed in spaced relation, pins connecting said members and located adjacent the ends thereof and adjustable blades mounted on said pins and foldable between the side members and beveled shoulders on said side members raised to the thickness of the adjacent blades forming stops for limiting the pivotal movement of others of said blades and positioning the blades at predetermined angles with respect to the side members, such of said blades as are thus positioned by the beveled shoulders having edges beveled to cooperate with the bevel of the shoulders.

5. A tool comprising a pair of side members disposed in spaced relation, pins connecting said members and located adjacent the ends thereoi and adjustable blades mounted on said pins and foldable between the side members and beveled shoulders on said side members raised to the thickness of the adjacent blades forming stops for limiting the pivotal movement of others of said blades and positioning the blades at predetermined angles with respect to the side members, such of said blades as are thus sitioned by the beveled shoulders having edges beveled to cooperate with the bevel of the shoulders, and other adjustable blades also mounted on said pins, the blades which are arranged to be positioned by said shoulders being provided with slots.

In witness whereof, I have hereunto set my hand this 14th day of July, 1923.

OTIS EAST.
