JACKSON JOHNSON, OF ROCHESTER, NEW YORK.

SPEOTFICATION forming part of Letters Patent No. 786,646, dated April 1, 1905. Application filed February 24, 1904. Serial No- 195,107.

To add whom it may cancel-It.-

Be it known that I, JAoksoN Joinrsorr, a citizen of the Dominion of Canada, residing in the city of Rochester, in the county of Monroe -and State of New York, have invented a new and useful Vertical Combination Shear-Gage for Cutting and Marking, hereinafter known as Johnsons Perfection Combination Shear- Gage, of which the following is a specification.

My invention relates to improvements in shear gages wherein a double adjustable clamp with pivoted and sliding connection is carried on a vertical bar which has a detachable base. Thus the combination of these and other detachable parts is used in conjunction with a pair of shears or otherwise, Figures 1 and 2.

The objects of my improvements are, first, to obtain the correct and uniform length of a ladys skirt; second, to obtain the uniform width of strips of cloth in cutting; third, to locate buttonholes, &c.. equidistant. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Fig. 1 is a perspective view of part of the combination in conjunction with shears for trimming the bottom of a skirt. Fig. 1 is a view of the triform arm removed. Fig. 1 is a view of the guide-wire removed. Fig. 1 is an edge view of the graduated bar. Fig. 1 is aface view of the same. View of the base-plate. Fig. 1 is a plan view thereof. Figs. 1, 2 show in side and edge views the removable spring-clasp designed for use with the clamp seen in Fig. 1 Figs. 1", 2 3 show in top. side, and edge view the clamp. Fig. 2 is a perspective view of the entire combination for marking the bottom of a skirt. Fig. 3 is a horizontal view of parts of the combination E, C, and B in Fig. 1, used in conjunction with shears for cutting strips of material of uniform width, also in conjunction with buttonhole-shears to locate the holes equidistant.

'lhroughout similar letters refer to similar parts.

The clamp member E, Fig. 1, has a pin N in one side and a set-screw G, Big. 2, in other Fig. 1 is an edge side entering small dents in. the ends of the rivet or screw which holds the shear-blades together, thus afi ording means of pivoted detachable connection with shears or other appliance, as shown in Fig. 1 and Fig. 2. The clamp member E has also two embossed loops O, which afford means of sliding on and detachably clampin it to the vertical bar C by the use of set-screw H. The vertical bar 0 is supported in a vertical position on detacha'ole base F by means of guide-wire B passing through the two embossed loops L and through the end of the vertical bar U. Thus guide-wire B and triform arm A (which also passes through one embossed loop M) form additional area of base. The combination thus assembled, as in Fig. 1, forms a gage by which, in conjunction with shears or other appliance, the uniform length of a skirt is obtained by cutting or otherwise. (See Figs. 1 and 2.)

As seen in Fig. 3, the device is adapted for cutting folds and other narrow pieces of clcth of uniform width. The guide B is run along the edge of the cloth and the shears sever the goods, making all strips of uniform width.

In Fig. 2 the device is arranged to form a gage for making a line around the bottom of a shirt at any desired point within eight inches from the floor. The graduated arm C extends vertically from the base F, as in Fig. 1, the clamp member E in this instance forming acrayon-holder, the crayon S being held in the clamp member E by a removable spring-clasp D, seen detached in Fig. 1 and held by the set-screw G.

In the use of the form seen in Fig. 1 the device may be stationary and the skirt moved with relation thereto, or vice versa, and in marking the buttonholes with the device, as in Fig. 2, the same course may be pursued.

What I claim my invention, and wish to secure by Letters Patent, is-

1. A graduated bar, a wire arm B carried ed with said bar, a clamp member adjustable on said bar, and means in the clamp member for holding the article to be carried thereby.

2. A graduated bar, a wire 3 carried at one end thereof, a base, an arm detachably supat one end thereof, a base detachahly connectl l l 1 said bar, and means in said clamp member 10 whereby said clump member will hold either a cutting-tool or a crayon-holder, as and for the purpose specified.

JACKSON JOHNSON.
