OYSTERFEAKE.
ToALL WHM ITAMAAY conocen:
Be it known that I, ASA BARRETT, ofthe city and county of Baltimore, and State of Mhryland, have 'inventedl a new and improved Oyster-Rake; and I do hereby d'eclnre that the lfollowing is j a full, clear, and
exact description 'of' the -cons'tiiuction'and operatien'f the' sortie, reference being had to the annexed drawings, making a partof this speciication,'in'which- Figure 1 is aperspetive view'. v Figure 2 is a' side elevation, a. portion of one of the rake-headsbeingbroken away, to show the interh This invention is a simple and easily-operated device, bypvbich oysters can be fished up from great deptnfs.
In the drnwngs, A A represent two rake-heads, hinged 'together along their upper edge, und lprovided withteeth a'ayef the form, and arranged in the manner shown in the draudngs. B is a heavy bar,'extending between the heads AA, being supported Aby ears b'b, -at either end ofthe rake.
The lobject of the bar is to furnish s u'iiicient weight to overcome tb'e force of' the spring S, which is coiied around the bnl', 01 applied in any other suitable manner, and so attached to the heads, on .eitherside of it, esv
to press 'their lower edges apart, and open the rake, when not eounteracterl by the Weightedl bar'.
C C are two crossed r'ods or bars, extending upwnrds from ythe two ral e-heads, and united at their top oy 'means of two rods :D` D; hinged to them, and a link, E, whichconnects the two rods D D, as shown-in iig. 1. From the link'E, e. chainor cord, F, extends up to the vessel, passing over a pulley, G, in the yard-arm, or
.in scrane, II. The rodsD aud'C :any be connected by a k'nuekle-join't,dd, if desired, so that theyvezm' bg The operation of this1 device is as i'ollowsi When lowered upon the oyster-bed, the'forceofvthe springs s s and the weight of the arms C C cause the teeth "to spread apart, assuming the position showni in fig. 1, But when, by means of the cord or chain,` the link E is drawn up, the upper ends of thearms are drawny togetberk closing the teeth together, and intercepting the oysters between them. The-weight of the bar Bidrawrsidown 'so heavily as to bring the teeth closely together, their ends interlocking, sorthat none of the oysters can escape. The device cnnbe lowered to any depth-where it is possible to find oysters, opera-ting fjust as easily and perfectly in deep' soundings as where the'water is shoaL It is cheap, simple in construction, and but little liable to get out of repair. i
Having-thus described my' invention, what I claim as new, and desire to secure by :Letters Patent, is The instrument above described, consisting ofi the rake-heads A A, teeth a a, spring S, and. weight B, in combination with the crossed rods or arms C O, and the connecting-rods D D, and link E, substantially as and for the purposefspeoied.
