Specification of Letters Patent.

To all whom it may concern Be itknown that 1, MILES GANDY, a citizen of the United States, and a resident of Cedarville, Cumberland county, NewoJersey, have invented certain Improvements in Oyster-Dredge Catchers, of which the fol lowing is "a specification;

and the object of my invention is to facilitate thehandling of the dredge on andofl the boat, more particularly in launchingthe dredge'from the 'side'of the boat after-lit hasbeen emptiedof the oysters.

My invention comprises a supplemental: support for thedredge, which support is so mounted and arranged as to gIG Zt tlY 'f EL cilitate the launching of the dredge and materially reduce thehard work usually at- These and otherfeatures of my invention are more fully described hereinafter, reference being had tothe accompanying drawings, in which:

"such frame carrying the rake and the bag.

After the oystersihav'e been caught,- the dredge. is. of course, "hauled up over the' side of the ,boat,and oyster boats are usually provided with aroller of cons derable size, subsequently the dredge frame is drawn.

As ordinarily constructed and/as; operated, the. dredge is dragged over the s de ofthe boat and over the roller"until the re'a'r*end of the dredge rests upon the roller. The

Locatedinside themain -roller2 and dis it posed above the same is an element whichmay comprise a'smaller roller or a bar 5, 10 0" i from thebar as to ride .over .theedge of either thev dredge or the catching device.

which element is carried by a frame 6, which may be journaled or hinged in brackets 7, and carries a suitable torsion spring 8Whose+ normal tendency is to keep the roller or bar 5 close up against the roller 2. When the dredge is dragged inboard, it passesup over the main roller 2 and the supplemental roller (or bar) 5 until the teeth 9 of the dredge come: over the side, and these catch against the supplemental roller (or bar) 5. in the manner shown in Fig. 2, moving the roller or bar and its. frame against the ten? sion of the spring, and preventing the dredge dropping onto the deck. =Ihe oysters are now emptied on the deck, and upon the dredge being relieved of this; weight, the spring 8 will react and move the dredge outboard a slight distance to the position shown in Fig. 3, so that it only becomes necessary for the men to push it over the rollers 5 and 2the rest of the distance for proper launching; I t

The swinging frame 6 is shown as pivotally mounted or hinged at the side of the boat. It will be understood, however, that this structure may be hinged at any convenient point on the boat, so long as it is in proper position with relation to the roller 2 and has proper en agement with the torsion spring to effect retractive movement thereotwith the dredge.

It will be understood, of course, that I; do not wish to be limited to the particular character of spring supporting means employed, since any form of spring that will yield under the weight of the full dredge and react to move the dredge slightly out board .when the oysters are emptied, may be employed.

As noted, I may use a bar instead of the supplemental roller 5, and my claims are intended to cover the use of either orboth devices.

In some instances, particularly where the draft of" the chain is at a'low angle, it may be desirable to dispose the catching means much closer to, the main roller 2, and for this purposeI may employ a structure such as shown in Fig. 4, in'which a plate or bar 5 with a relatively sharp edge is carried by the frame 6 in lieu of the supplemental roller 5.

In either instance, I prefer a construction that may be moved to such a position as'tov release the rake of the dredge should the hauling gear bring the latter too far into. boat. Under such conditions, .the catcher will be forced down against the tension of the spring, and the rake teeth will ride over the roller or be lifted so. high the same; permitting the, dredge to fall onto the deck without danger ofdfamaging I claim:
