TINMANS TONGS.

SPECIFICATION formingpart of Letters Patent No. 256,556, dated April 18, 1882.

Application filed January 9,7, 1882. (No model.)

To all whom it may concern:

Be it known that I, CHARLES R. EVERSON,

a citizen of the United States, and a resident of Macedon, Wayne county, New York, have invented certain Improvements in Tinmens Tongs, of which the following is a specification.

1 My invention relates to that class of tongs with broad flat blades used for bending plates of tin in roofing or in the making of eavestroughs; and my invention consists in constructing the tongs, as described hereinafter, so as to bend up flanges of any requireddepth less or greater than that of the blades, and whether the edges of said flanges are plain or ribbed.

In the drawings, Figure l is an edge view of my improved tongs. Fig. 2 is a side view,and Fig. 3 a view showing the trough.

The legs H H are pivoted by the bolt ac, and

ble manner, but between the rivet and the blades d d are curved or spread apart, so as to leave a space, y, for the purpose hereinafter described. The blades d d are long, narrow, 5

legs H E that they will lieflat together when said legs are closed, as shown in Fig. 1. Against guides s s on the blade d slide gages D D, each having a lug, 0, extending over the upper edges of both blades, and secured adjustably by screws f, which pass throughslots 12in the gages, as shown. I

The ton gs thus constructed are used in the ordinary manner 5 but. the extent of metal turned up to make the flange may be exactly determined by setting the gages so as to leave between the lower edges of the blades and the lips c the distance equal to the depth of the flange to be made. i

As ordinarily made, tinners tongs cannot be used for turning up flanges upon plates beaded above the latter are constructed in any suitabeveled at the lower edges, and so set on the or ribbed prior to bending. By spreading the legs to leave a sp c 3/, between the same above the blades, I leave room for the reception of the bead, as shown, so that the plate 5 can be as readily bent as it it had a plain edge.

- The gages may be formed and secured adjust-ably in any'suitable manner, and blades of any required forms and dimensions may be employed. 0

By the use of this tool I am enabled to make a trough of the form shown in Fig. 3, the same consisting of a flat sheet havinga rib at one edge and plain at the opposite edge, which may be inserted between the shingles while all the sheets are soldered flat together. The above-described tongs is then used to turn up the outer portion with its rib at about right angles to .the part lying upon the roof, thus forming a -shaped trough, which will et'fect- 6o ively collect and conduct the water, and which may be made and applied with less labor and expense than those of the ordinary construc-' tion.

I do not here claim the trough or manner of making the same, as this may form the subject of a separate application for Letters Patent.

I claim- A tinners tongs consisting of pivoted crosslegs H H and blades d d ,the legs being spread apart above the blades, and the latter being provided with gages secured adj ustabl y to one blade and extending over the upper edges of both, substantially as set forth.

Intestimony whereofI have signed my name to this specification in the presence of two subscribing witnesses.

CHAS. It. EVERSON.
