ALBERT A. \VAYMIRE, OF \VOODS, OREGON.

COMBINATION-TOOL.

SPECIFICATION forming part of Letters Patent- No, 738,130, dated September 1, 1903.

Application filed February 2, 1903. Serial No. 141,682. (No model.)

To all whom it may concern:

Be it known that I, ALBERT A. WAYMIRE, a citizen of the United States, residing at 'Woods, in the county of Tillamook and State of Oregon, have invented new and useful Im lVith these and other objects in view, which will appear as the nature of the invention is better understood, the same consists in the novel construction and combination of parts of the combination-tool of the character defined, as will be hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, and in which like characters of reference indicate corresponding parts, there is illustrated one form of embodiment of the invention capable of carrying the same into practical operation, it being understood th at the elements therein exhibited may be varied or changed as to shape, proportion, and exact manner of assemblage without departing from the spirit thereof.

In the drawings, Figure 1 is a view in elevation of a combination-tool constructed in accordance with the present invention. Fig. 2 is a detail view of the handle. Fig. 3 is a similar view of the blade. Fig. 4 is a view in longitudinal section.

Referring to the drawings, 1 designates the handle, and 2 the blade. These parts may be made of any suitable material, preferably of metal, and are divided by graduation-marks into increments of an inch or, if preferred, into divisions of the metric system. As a matter of further specific improvement if so desired one side of the handle and of the blade may be provided with the usual divisions of an inch and the other side of each with divisions of the metric scale, and as this will be readily understood detailed description thereof is deemed unnecessary. The handle and the blade may be made of any preferred length, and in this instance the blade will represent a length of two feet and the handle a length of one foot, so that when the parts are straightened out or are in alinement the device may be used as a yard-stick.

The blade is provided at one end with a threaded orifice 3, surrounding which is a protractor f to be used in determining different angles of bevels that it may be desired to strike, and the handle is provided with an unthreaded orifice 5, through which passes a setscrew 6, the lower portion of which is threaded to engage the threads of the opening 3 and is provided with a collar 7 to bear upon the upper side of the handle, thus to effect clamping of the two parts together. The upper end of the set-screw is provided with flanges or projections S as usual to permit the turning of the device, and its lower portion terminates in a point 9, which projects beyond the blade and is designed to constitute both a fulcrum and a pivot-point for holding the blade in position while the handle is being turned about the set-screw when the device is used as a com pass, to effect which the handle is provided with a plurality of alined orifices 10, through which the point of a pencil or other scribing instrument will be passed in inscribing circles or semicircles. The orifices may be placed at anyv preferred distance apart-say oneeighth of an inch-thereby affording an extended range of usefulness for the device. In order that circles or semicircles may be inscribed that could not be struck from the orifices as shown, supplemental orifices 11 may be provided, arranged in staggered order with orifices 10, so that under the arrangement provided a circle of any desired diameter may be struck. The end of the handle adjacent to the orifice 5 terminates in a pointer 12, which is designed to coact with the graduation-marks of the protractor in determining the angle of the bevel to be out. In using the device asa try-square the handle will be set exactly at right angles with the blade in the usual manner and be clamped by said screw. Where used as a bevel, the handle may be set at the re quired angle by coaction between the pointer 12 and the graduation marks of the pro- ICO tractor. Where used as a pair of calipers, the handle may beset at an angle to the blade, and the article to be calipered may be inserted between the handle and the blade, as will be readily understood. here employed as a compass, the pivot 9 will be sunk into the surface upon which the circle is inscribed and the point of a pencil or scriber is inserted through one of the orifices 10 or 11, and the handle will then be swung in a circle, with the shank of the set-screw as the fulcrum. The provision of the pivot 9 in this connection is essential, inasmuch as it will operate positively to hold the blade against any lateral movement when once positioned. lVhere employed as a gage, the handle is adjusted at right angles to the blade and the blade is pressed against the side of the object to be gaged, and a pencil or scriber is passed through the appropriate orifice in the handle according to the line to be marked.

It will be seen from the foregoing description that while the device of this invention is exceedingly simple in construction it combines in a novel and feasible manner all the elements necessary and that are usually accomplished by six implements-namely, a rule, try-square, bevel, calipers, compass, and gage.

I claim- 1. A device of the class described, comprising a folding graduated blade and handle, each provided with a terminal orifice, the orifice of the blade being threaded and surrounded by a protractor-scale and the orifice of the handle being smooth, and a set-screw passing through the said orifices and provided with a pointed extremity projecting beyond the face of the blade to forma fulcrum, substantially as described.

2. A device of the class described, comprising a folding graduated blade and handle, each provided with a terminal orifice, the orifice of the blade being threaded and surrounded by a protractor-scale and the orifice of the handle being smooth, the handle being provided with a plurality of orifices and with a terminal pointer to coact with the protractor-scale, and a screw passing through the said orifices and provided with a pointed extremity projecting beyond the face of the blade to form a fulcrum, substantially as described.

3. A device of the class described comprising a folding graduated blade and handle, each provided with a terminal orifice, the orifice of the blade being surrounded by a protractor-scale, and the handle being provided with a plurality of rows of orifices arranged in staggered order and with aterminal pointer to coact with the protractor-scale, and a set-screw engaging the said orifices and provided with a point or pivot, constituting a fulcrum.

In testimony whereof I have hereunto set my hand in presence of two-subscribing witnesses.

ALBERT A. lVAYMIRE.
