CHARLES A. SCANLAN, OF CHARLESTON, SOUTH CAROLINA, ASSIGNOR OF ONE-FIFTH HIS RIGHT TO'ELISHA LINDSAY HALSEY, OF SAME PLACE.
IMPROVEMENT IN DREDGlNe-TONGS.
Specification forming part of Letters Patent No. 201,559, dated March 19, 1878 g application filed Y October 10, 1877.
are drawn together by a cord, to retain the,
rock within the graspy of the blades.
In the accompanying drawings, Figure 1 is a side view of the tongs, omitting a portion of the length of the handles. Fig. 2 is a back view of the same. Fig. 3 is a side view on a larger scale, illustrating certain modifications.
A A are a pair of handles of ordinary construction, pivoted together at a and secured in sockets B B of the blades, which blades are each formed with any desirable number of teeth, C C C, firmly tied together by throughbolts D, which clamp the teeth against the interposed sleeves E. The bolts D also secure the lower ends of brace-rods F, the upper ends of which are bolted at f to the upper part ofthe blade-socket, the bolt f, which thus secures them, being passed through the handle, so as to retain it. G G are eyes, which may project laterally from the necks of the blades, or may project toward each other, as preferred. They are employed for the reception of a rope or chain, H, which serves to hold the blades together in drawing up a piece of rock.
The implement is found highly useful in gathering phosphate-rock from beneath the water, and may be advantageously employed in all similar operations. The tongs may be made of iron or steel.
In the modification shown in Fig. 3 the sockets B B extend above the pivot a. The eyes G G may be located, as shown in Figs. l and 2, atthe upper ends of the brace-rods F, or they may be located on the side of each blade, as shown in Fig. 3, or they may be placed at any intermediate point, as may be preferred, or as the form and construction of the tongs may require. The brace-rods F may be bowed, as illustrated in Fig. 1, so as to admit rocks of any length between the blades, or they may extend straight across the bow of the blades, as illustrated in Fig. 3,
so as to retain small pieces of rock between the jaws.
By extending the rods in a straight line from the pivot a to near the extremities of the blades, as shown in Fig. 3, the said-rods are adapted to brace and support the blades, while they may be of smaller size.
Having thus described my invention, the following is what I claim as new and desire to secure by Letters Patent:
The dredging-tongs constructed with handles A A, teeth C C, bolts D D, sleeves E E, braces F F, eyes Gr Gr, and rope or chain H, as and for the purposes set forth.
C. A. SCANLAN.
