GAGE FOR MARKING SPOUTING.

SPECIFICATION forming part of Letters Patent No. 407,288, dated July 16, 1889.

Application filed February 23, 1889. Serial No. 300,856. (No model.)

To all whom it may concern.-

Be it known that 1, Louis S. FLETCHER, residing at Blue Springs, in the county of Gage and State of Nebraska, have invented certain new and useful Improvements in Marking-Gages for Spouting, &c., of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to a spout-gage for carpenters, millwrights, and others.

The object of the invention is to producea gage by which a spout or brace can be marked and cut to fit and connect conveyer or other spouts or timbers which stand at Various angles to each other.

In mills and elevators many spouts are used for the passage of grain, flour, 850. These spouts are generally rectangular Wooden spouts. The spouts stand at all sorts of angles and inclines with relation to each other. It frequently becomes desirable to connect these spouts with a branch leading from one to another, and it is a diflicult matter to determine the exact angle of junction, so as to cut the connecting spout to fit. To overcome this difficulty I have devised the present invention.

Figure 1 is a perspective view of my gage, parts being broken away. Fig. 2 is a crosssection at w 00, Fig. 1. Fig. 3 shows a modification of the extensible staff or standard. Figs. 4 and 5 are perspective views of spouts and connections.

A A, Figs. 4 and 5, represent spouts or grainconductors. B B represent branch pipes connecting the same. To make proper connections it is obvious that it is desirable to lay off the angles at C O O, &c., and cut the branch pipes to fit exactly into the position they are expected to occupy, and it is also desirable to cut the pipe at a single operation and not to depend on frequent trials, as is generally the practice.

D D, Figs. 1, 2, and 3, indicate an extensible staff or standard made in sections. The

central portion D may be an angular piece of metal or wood, as in Fig. 1, or a tube, as in Fig. 3, the sections sliding or telescoping on each other longitudinally. As many sections may be used as the length of the spout to be cut may render necessary. The end sections E E of the stafi D D' are anglepieces, preferably of metal, and each side plate is slotted at F near the outer end of the section. Agage-plate G, having a cross-slot H near its inner end, is attached to the section E by a set-screw I. The gage-plates G will thus extend outward from the corner at the same angle as the plates forming the section E; but the gage-plates can be swung to any angle about their pivots I, and can also be moved to a little distance along the slots F. By turning up the set screws or clamps the gage-plates can be held in any position to which they may have been adjusted.

In use the staff is extended along the line the branch pipe is to occupy until the proper length is determined. Then the angle-plates E are placed against the corners of the spouts A and the gages set to accord with the opening in the sides of these pipes or spouts. The device can then be placed against a branch spout-section, and this section marked to the exact length and angle necessary to make an exact fit. The spout-section can then be sawed to fit in place as a branch, suitable cut-oifs being provided in the main spouts.

It is obvious that the gage may be used in the same way to mark off braces between timbers, &c.

The section D, Fig. 3, is then brought down at the end S to form a socket for a tubular extension-piece. Other common forms may be used.

What I claim is 1. The combination, with an extensible body or staff, of a plate having two plane faces at an angle to each other, and a gage piece attached to each of the faces and each adjustable to any angle in the plane of the face, substantially as described.

2. The combination, with the extensible body, of the angle-plate perforated near its end, a perforated gage-piece secured to each face of the angle-plate and movable in the plane of that face, and a clamp for securing each gage in adju 31c (1 position, substantially In testimony whereof Iaflix mysignature in as described. presence of two witnesses.
