To all whom, it may concern:

Be it-known that I, ALPHONZO EUGENE ,MEEK, of Dallas, in thecounty of Dallas and State of Texas, have invented a new and use ful Improvement in Combination-Tools, of which the following is a specification,

architects, d raftsmen, millwrights, machinists, and all metal and wood workers, and which shall be ,light and convenient 'to carry and may be quickly adjusted to its different positions for use, in the manner hereinafter de-' scribed.

of construction and combinations of parts, as

I will be hereinafter described and claimed.

In the drawings, Figures 1 and 2 are respectively front and rear views of the device. Fig: 3 is an edge view thereof. Fig. 4 is a section on line m m; Fig. 1. .Fig. 5 is a detail view of the thread-gage;'.Fig. 6, a detail view of the level; Fig. 7 is a detail view of the inbevels, an inclinometer, wire'iron andthread gages, protractor, scale of cuts and lengths of all the angles around the circle, and tables useful 'to those in the mechanic arts. The main bar'or body A is slotted from one end at a, forming, a way for the quadrant-blade B, and from its opposite end at a forming a way for the angle-blade O, which forms a part of the. inclinometer, and the blades B and C are secured by screws D and E, having winged nuts (1 and e, by the tightening of which their respective blades may be secured .in any-desired adjustment. The front face ,of the body adjacent the openirig-fer-scrw" E is graduated at f, and a weighted pointerF is pivoted on said screw E and registers along said graduation f, the'body 'A, blade 0,.pivot,

and pointer thus forminga'n incl'inometer.

The openings of blade 0, through which the direction of length of said blade 0, so such A when the device is folded up. [It-willlbe noticed that the 'slots a 06 form the body A into a main strip A and strips A A On or around the edge of the main strip A ar'eformed onthe edge of the section A, as

mark across the opposite edge of the section. Theprotractor. is used as any other prodotting or indic'ingon the graduated edge.

provided for it in the main strip A', such blade may be set into the slot at of the body I The spirit-level G is fitted to enter a socket screw-E passes, slotted'or eldngated the I I provide protractor-graduations for. use by platting-engineers- Such graduation-marks V will be seen in --Fig.- 3, and the center'isv a tractor by simply placing the tool onits fiat side, withthe center on any given point on a line; and the degree-points are noted by socket being undercut at one end 9 to receive J the end g of the level, and the opposite end v .of such level is held by. means of ascrew G Fig. 1.

such level when in position forming practiv cally a part ofthe main strip A, as shown in Onits front face the bodvAhasinscribed tables H H, giving the length of. the sections. of diflierent polygonal frames which it may be'desired to fit in or around circles. 3 d On its opposite or rear face the 'bodyA is graduated. into a scale of inches and fractions thereof; "The quadrant B pivots on screw D and has it's blade I) fitted to' be i'ncasedin slot at. The edges 1 and? of thequadrant'head arid blade form atrue fixed try-square. The outer edge 3 of the quadrant-head is curved in the Y 3 are of-a circle, and such .head is properly graduated on its front face at-4 to-form it into a protractor, while the front face of the blade I) of such quadrant is inscribed with information to'aid in ascertaining the circum- 4 ference of a circle, the side of asquare equal agiven' circle, the side of'a square which may be inscribed in a given circle, &c.

, In describingthe protractor-graduations 4 I be said to be not used or applied from'a; given on the quadrant of the bevel-blade they may center, as commonly known in, protractors;

but are arranged to be used to get the de-' grees of -inclination readily and quickly by architects, millwrights', machinists, and carpenters by taking the reading of the graduaduction requires various angles of incline, to

run which is ordinarily ascertained by the' millwright by a brief draft. This arrangement by degrees on a bevel-blade givesthe whole matter at a glance.

It will be understood that a dot or indicator-point may be formed in the wall of opening 0, by which to insure accuracy in reading the protractor graduation-lines.

The curved edge of the quadrant-head is formed with openings 5, forming a metal and wire gage.

I form through the quadrant-head openings 6 and 7, the former forming wood-screw gages, I

while the latter. serve as wire-gages and as gages for nail and screw heads.

n the screw D, between the quadrant and the stamp A I pivot the thread-gage I, formed in sections I I, the edges of which are formed a p to gage threads from 8 to 40, as will be understood from Figs. 2 and 5.

When not in use, the inclinometer-blade C. may beslipped up in slot of and the shank" of the quadrant be turned into the slot a, when or for storing away.

It will be seen that the'slotting of the body at a. a enables the incasing f the plates 0 b the device .is in compact shape for carrying in said body and so protects such plat-es'when I not use. For this reason I prefer to pivoti the plates to the body in such slots. I also; prefer to provide a socket F, in which to seat; the pointer F and to providethe graduations a curved edge, and havinggraduations formf on the base wall of such socket.

It is my purpose to-construct the device of steel, and to mark the graduations and tables therein. v

The center gage-plate J is formed with a recess j, having its opposite walls j j diver'g-:

ing outwardly, and is supported on the main bar, being provided with openings j to receive steady pins or studs j on said bar, so the placing of the plate J on the bar with open-' ings 3 over pins 3' will insure the proper arrangement of the saidplate with reference to the'edge of the main bar, so the latter will be at a right angle to a line that will equally di-.

vide anglebetween the walls j of the recess in plate J. The plate J is secured to the main bar by a screw J, as shown. By the arrangement of the gage-plate as described,

such lines will mark the center of the shaft.

' Having thus described my invention, what I claim as new is- 1. The combination of the main bar, the center gage-plate having a recess formed with diverging walls, fastenings for securing the gage-plate to the main bar,with the side edge of such bar at right angles to a line equally 'dividingthe angle between the walls of the recess in the gage-plate, and a blade B, connected with said main bar, all substantially as described,wh'ereby when blade B is turned at right angles to the main bar one of the edges ofsaid blade will equally divide the angle betweenthe walls of the, recess in the gage-plate, substantially as set forth.

2. The combinationof the main bar having studsji the plate J, having recess j, and openings 3' to receive studs 3", and the quadrantplate having the edge of its blade equally dividing the -anglebetween the walls of recess ,7', substantially as set forth.

3. A'compound tool, substantially as described, comprising the body A, having a level, the inclinometer-blade pivoted to such body, the pivoted pointer, the graduations along which said pointer registers, and the quadrant pivoted to said "body, all substan- I tially as set forth.

; 4. The compound tool comprising the body A, the plate 0, having slot 0, the screw connecting said plate 0 to the body, the pointer F, and the graduations f, along which said pointer registers, the quadrant-plate pivoted to the body and having its head formed with ing slots a, a formed from its opposite ends, and havingasocket F and graduations f, the level on said body, the plate 0, the screw for pivoting said plate 0 tothe IIO body, the pivoted pointer registering along plate and the strip A of the body, all sub- 1grafiuations f, the quadrant-plate having a st'antiztlly as and for the purposes specified.

lea and a shank, the latter being fitted to slot at, and the head having Wire and metal ALPHONZ-O EUGENE MEEK' 5 gage, the screw for pivoting the quadrant-. lVitnesses:
