IMPROVEMENT IN ROCFING-TONGS.

The Schedule referred to in these Letter s Patent and making part of the name.

I, GEORGE E. TAYLOR, of Philadelphia, county of Philadelphia, State of Pennsylvania., have invented an Improvement in Rowing-Tongs, of which the following is a specication.

Nature amd Object of the Invention.

Description of the Accompanying Drawing.

Figure 1 is a perspective view of my improved roofing-tongs;

Figure 2, a vertical section of the lower portion of the tongs; and

Figures 3 ande: illustrate a modification of my invention.

General Description.

A and A' are the two arms of the tongs, jointed at a, in the usual manner, and to each arm is secured a plate, B, the two plates serving to turn up the edges of the tinned roofing-sheet x.

In ordinary tongs of this class, there are xed pins Or stops in one plate, projecting through `holes in the i other plate, these pins determining the extent to which the edges of the roofing-sheets have to be turned up; hence, as deeper flanges have to be formed, in some instances, than in others, the roofer must furnish himself with a number of tongs, havingpins or stops at` diierent'distances from the lower edges of the plates B and B'.

In my improved tongs, I avoid this expense, by so securing two or more pins or stops to one of the plates,

that they can be readily detached and fitted to any one of a number oi' holes in the said plate, the said ,holes being at different distances from the lower edge oi' the same, and the oppositeplate being provided with similar coinciding holes, through which the pins may project.

Thus, in gs. 1 and 2, each plate B has a set of three holes on each side of the arms of the tongs, the three holes of each set being at different distances apart from the lower edge'of the plate, and the holes ot' one plate coinciding with those of the other.

The pin al is provided with a collar, hearing against the inside of one ofthe plates, and with a nut, hearing on the opposite side of the same plate, so that on removing the nut, the pin may be detached from one hole` iitted to another, and there confined by the nut.

In figs. 3 and 4, the plates B B are provided with diagonal slots, the pins being secured, by a thumb-n ut, f, to\the slots of one plate, and passing freely through the coinciding slots of the Opposite plate, so that the pins admitoi' Vthe desired adjustment to and from the lower edges of the plate.

It will be evident, Without further description, that my improved tongs may be readily adjusted for tnrn ing up ilanges of udifferent depths on the edges of roofing-sheets, and consequently, that a supply of Ordinany tongs, with a diierent arrangement of fixed stops, may be dispensed with.

Ola/im.

The combination, with roongatongs, of adjustable pins or stops, substantially in the manner described.

In testimony whereof, I haveY signed my name to this specitication, in the presence of two subscribing witnesses.
