carpenters gages in which toothed wheels are made to revolve on adjustable axles and mark the wood over which they roll; and the objects of my invention are, first, to provide toothed marking-wheels that will climb over uneven-grained wood and make a plain mark or marks and so provided with sleeve-like hubs as to. prevent them from wabblingj sec- 0nd, to provide adjustable arms on which the marking-wheels are attached, so that said arms can be moved to adjust the wheels to desired distances from the gage-base and from each other, and, third, to provide means for extending the length of the gage-rods and telescoping them to a compact form when not in use; fourth, to provide means to fixthe rods and their connections rigidly at any desired position of adjustment; fifth, to provide a practical pivot on the gage-base for the drawing of arcs of circles. I attain these objects by means of the mechanism illustrated in the accompanying drawings, in which.'

used. 3 is a front view of. one of the marking-wheels, showing the teeth w w.

Similar letters refer to similar parts throughout the several views. 1

The gage-base or shoulder-slide e constitutes the base or framework of the entire instrument.

In the gage-base eis a large cylindrical hole, through which tube 3/ slides loosely and is retained therein by means of thumb-screw f being tightened on it.. In tube 3 is inserted a longer 'tu be h, which slides loosely through it, and upon the front end of said tube y is rigidly attached an' annular shoulder 6, against which shoulder works the sleeve-hub t of marking-wheel Z. Tube 71 is still longer than tube and works loosely within tube it. Tube h is used simply as an extension-tube for the purpose of extending the length of the gagearm and may be of any desired length that the particular class of work may require.

face of tube It.

Tube y has slots in the end where it is covered by band-nut a and has threads cut on the outer surface'of that end to the purpose of receiving band-nut a.

toolis not in use, tube gmay be drawn to the right till marking-wheel Z is within the recess 9 and then thumb-screw f tightened against Screwingon band-nut a tightens tube g on tube h and prevents a slipping motion between them. When the tube 1 at the place where tube y has slots cut through it, and the pressure of screw f will spring the side of tube y against tube A, and

thus hold both y and h firmly. Tube z'is supposed to be shorter usually than tube It, so

that the spring m maybe always held within tube It, and thus serve its sole purpose as a friction-spring to prevent a slipping motion operator.

In using the gage with a short tube it, as

between tubes h and dunless desired the shown in the Figs. 2 and 3, loosen band-nut a and pull tube It to the right till it covers friction-spring m. Then tighten band-nut a,

which will hold tubes y and h rigidly together. Then slip tube .y to the right till marking-wheell is fully within recess p, and

then tighten thumb-screw f. Then tube z' can be slipped to the left as far as desired and will be held in place by means of friction-spring m pressing against the inner sur- Should it be desired to set both marking-wheels j and Z, they can be adjusted by sliding their respective tubes carryingthem. In the left or front end of tube 71 is inserted and rigidly fastened a small journaltube 70, which is allowed to protrude from the left end of tube'c', so as to form a journal or bearing for the hub s of marking-wheel j, which is held in place by the screw r. On the top of gage-base e is a hinged tongue at, having a cone-shaped point 0, which is used as a pivot for drawing arcs or circles with the gage. To use this pivot, the tongue at is lifted fromthe groove d and turned up and to the left and dropped into said groove dagain, so that p not in use, it can be latched down in the grooved out of the way, as shown in Figs. 1 and 2, being hinged on base e by pin'c.

On tube 3 there is a scale of inches and subdivisions of inches from marking-wheel Z to the shoulder z of the gage-base e, the said scale being marked on the outer surface of tube y, measuring from the right-hand side or rear of the gage-base e to the right on tube y, and also on tube 2' there is a scale of inches and subdivisions of inches showing the distance between marking-wheel j and markingwheel Z, and the scale counts to the right from marking-wheel f. In using the scale on tube d it is intended that tube h will be shoved or pulled back out of sight under marking-wheel Z, so that the scale on tube a can be plainly seen.

In using a single wheel to make a single mark with the gage it is intended to have wheel Z rigidly held against shoulder .2 by tightening screw f.

I am aware that prior to my invention carpenters gages with sliding arm and with adjustable markers have been used and that toothed marking-wheels have been used on them for the same or various purposes. I therefore do not claim such a combination as I have herein described, broadly; but' What I do claim as my invention, and desire to secure by Letters Patent, is

1. In a carpenters gage the base 0, provided with recesses 9 to receive marking-wheels Z and j, and with groove (Z, to receive the hinged tongue n, which carries pivot-point 0, and with thumb-screwf, so arranged and threaded as to clamp rigidly tube y; all in combination with tubes 1 Z1. and vi, substantially as described and for the purposes set forth.

2. In a carpenters or woodworkers gage, or marking instrument, tubular rod 1', provided with toothed marking-wheel j, secured to it by means of tube-journal Z: and screw and slotted tube y, provided with toothed marking"- wheel Z annular flange Z; and band-nut u; all in combination with tube /1. and gage-base 4', substantially as described and for the purposes set forth.

3. In a marking-gage the tube 1', provided with the friction-spring m, fastened to tube X at a, and made to intercept the inner surface of tube Z1. to prevent a sliding motion with slight force; in combination with tubes 1/ and h and gage-base 0, all substantially as described and for the purposes set forth.

t. In a marking-gage, the hinged tongue/1, carrying pivot-point 0, attached to gage-base (a; all in combination with tubes 1/ and having a graduated measure-scale on them; substantially as described and for the purposes set forth.

In testimony whereof I have subscribed my name to this specification in the presence of the two following witnesses.

GEORGE \V. PEYTON.
