I Letters Patent No. 110,619, dated January 3, 1871; antedated December 21, 1870.

IM PROVEMENT IN STO N E-DRAGS.

The Schedule referred to in these Letters Patent and making part of the same.

To all persons to whom these presents may come:

Be it known that I, ELIJAH O. ALLEN, of Deerfield, of the county of Franklin, of the State of Mas- 1 has-"been attended with much necessary waste of 'material:

In earrying out my invention, I construct each of the sections in separate pieces, that is, a bottom plank and a bow-plank, which Iv arrange end to end, and fasten to a separate metallicconnection.

In'the drawing, each of the sections is represented as composed of a bottom plank, a, and a bow-plank, b, there being usually three of the sections which are arranged edge to edge in manner as shown.

Themetallic connection shown at A is to be cast in one piece of metal, and consists of a bent base plate, 0, furnished with a series of triangular ribs, d, arranged across it, and in the hollow of it in manner vas represented, the two next the middle of the plate being connected at their front ends by a cross-rib, e, directly in rear of the middle-of which is an elongated slot, j; which is made through the connection A, and continued through the bow of the drag,

The' ribs not only serve to strengthen the connection-piece but to sustain stones when laid on them,

and to prevent such stones from jamming or injuring the links of the draft-chain when inserted in the slot.

The connection-piece laid on the angle between the bow and bottom planks, is to be secured to thBlILby screws g g, or by bolts or rivets, and the bow-planks b b b, are to be further held together by a head-bar or piece, 13, extended across and fastened to them,

the same being arranged as represented.

The usualguard-ledges h i i are to :be bolted to the end and sides of the bottom, audio rise above such, in manner as shown in the drawing. I

A drag so made is not only much stronger and bet-' ter'than one as constructed in manner as herein first described, but is easier of repair, and more durable.

I claim as a new or improved manufiicture- 1. A stone-drag,'as constructed, with separate bottom and bow-planks ab, and a metallic connection,

A, as described, arranged. and combined together, and with guard-ledges h e e, and a head piece, B, all substantially'as specified;

2. The metallic connection A, as composed of the base, bent and slotted as described, the support or guard-ribs, and the cross-rib, arranged and cast in one piece, as set forth.
