.D'REDGE FOR SHELL-FISH.

' SPECIFICATION forming part of Letters Patent No. 279,373, dated June 12, 1883.

Application filed March 27,1883. (No model.)

To all whom it may concern:

Be it known thatl, -AUGUSTUS F. FRIEND, of Gravesend, in the county of Kings and State of New York, have invented a new and useful Improvement in Dredges for Clams and other Shell-Fish, of which the following 7 is a full, clear, and exact description.

7 Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts of all the figures.

Figure 1 is a plan view of my improvement, part being broken away. Fig. 2 is a sec tional side elevation of the same, taken through the line x m, Fig. 1. Fig. 3 is a rear elevation of one of the gage-wheels, its axle, and a part of the draw-bar. I

The object of this invention is to facilitate the digging of clams and other shell-fish.

The invention consists .of the combination and arrangement of parts substantially as hereinafter fully set forth and claimed.

A represents the draw chain or rope, the rear end of which is branched, or is attached to a bail, B. The ends of the branches or bail of the draw-chain are connected by clevises G or other suitable means with the draw-bar 1), upon the opposite side of and equally distant from its center.

In the ends of the draw-bar D are formed holes to receive the upright arms of the right angled axles E, which are secured in place by set-screws F, so that by loosening the said set-screws the said axles can be raised and lowered to cause the machine to work deeper or SllflllOWGl in the ground, as maybe required.

Upon the outer arms of the axles E are placed wheels or shoes G to roll or slide upon the surface of the ground and support the forward end of the machine at the required ele 'vation.

To the inclined bars of the plow-plate J are attached the forward ends of the parallel bars or rods K, the rear ends of which are attached to the rear bar of the said plow-plate. The rods K are placed at such a distance apart that. the clams or othenshell-fish cannot pass through the spaces between them.

, To the rear bar of the plow-plate J is hinged the cross-bar L, to which are attached the forward ends of the bars or rods M, which are an isosceles triangle, and has its middle part parallel with each other and at such a dis= tance apart that the clams or other shell-fish cannot pass through the spaces between them, while the sand will be allowed to pass freely. The rear ends of .the bars or rods M are at= tached to a cross-bar, N, which is made longer than the cross-bar L, and is provided at its ends with wheels or shoes 0 to move along the surface of the ground. Vith this construction the screen L M N, as the plow H J K is drawn forward, will be drawn forward in an inclined position, its forward end being hinged to the said plow beneath the surface of the ground, and its rear end being held above the surface of the ground by the shoes 0, so, that the sand will pass through the spaces between the rods M, while the clams or other shell-fish will slide up the rods M to the surface of the ground and pass off the upper end of the screen L M N.

To the rear edge of the cross-bar N is at tached the lower part of the mouth of the bag P, which is made of woven wire or chains andwith the upper part of itsmouth extended farther forward than the lower part. edge of the upper part of the mouth of the bag I is attached to a cross-bar, Q, to the ends of which are attached the rear ends of wires orchains The forward ends of the wires or chains B are attached to the ends of a crossbar, S, which is attached at its center to the plow-beam I-I, above the forward part of the plow-plate J. With this CO11S'D1ll0hl01],QS the shell-fish pass from the rear end of the screen L M N they are received in the bag 1 and detained while any sand that m be with them is washed out by the water.

In a slot in the forward part of the plow- The L beam H is pivoted at its angle the lever T, the lower arm of which projects to. the rearward and is curved upward, as shown'in Fig. 2, to adapt it to serve as a shoe when forced down into contact with the ground.

To the end of the upper arm of the lever T is attached the end of a cord, U, which passes back to and around a pulley, V, pivoted to a support attached to the middle part of the cross-bar S. From the pulley V the cord U passes along the draw-chain A to the place where the power is applied, so that it can be conveniently reached and operated. with this construction, when the cord U is drawn upon, the lower arm of the lever T will be forced down upon the ground, raising the for ward end of the'plow beam H and the point of the plow-plate J, and causing the plow to run out of the ground, so that the machine can bev 'bentlwer T, the cord U, and the pulley V,

substantially as herein shown and described, whereby the point of the plow-beam can be raised to cause the plow to run out of the 1 ground, as set forth.

AUGUSTUS r. FRIEND.
