lteflgthule retentir in their Estufa atgnt animating ont of therme Be it known that I, SAMUELV S. Slnmof Newport, iu the countyof Cumberland, and State of New Jersey,

y have invented a newaiidiiipiovecl Oyster-Winder; and I do hereby declare y that the followingis a tull, clear,

and exact description thereof which will enable others skilled. in the vatto make and use the same, 'r'ei`erenee being had to the accompanying drawings, forming part of this specification.

Figure represents a f ront 'elevation,partly in section, of ,my-improved oyster-Winder.

Figure'Z is aside elevation, partly in section, of thejsame. l Figures 3 and 4 are detailside views of the samen Similar lettersof reference indicate corresponding parts.

This invention relates to-a new device, tobe 'used on boats, for winding` up oyster-d-redges, and its objectv is'to ,prevent-the reversing of the crank-shaft, in case t'he dredge strikes against a rock, or some other could also not he arrested, unless` the boat was stopped.

' Myimprovedwiuder is so arranged that, it' the'dredge is arrested by an obstruction, the -drain around which the rope is'wound will be automatically thrown out of gear with the crank-shaft, and the latter will notV at all bea'eoted by theensuing backwardmovement of the drum. i

',lhe' invention consists in theapplication'ot sliding drums around the winding-shafts, and is the device for throwing thesamo intl gear with each other; also, in the device" for holding them out of gear, when disengaged by the detention of the dredge. I

'I A, 'in the drawing, lrepres'entsrthe frame of my improved oy's'ter-wix'xder. The sam'e isu of suitable size andA shape, and made of suitable material, enough to support the winding-gear', and the weight attached tothe same,

- The frame' is intended to be setup in an oyster-boat, and in it are the hearings of one or more horizontal shafts,

B B, which are each provided with la crank, a, by means of which they'c'au be turned. On each axle, B, is mounted a drum, C, which can' turn loose on-,the shaft, and 'can also slide on the Bange. To 'one end of each drum, C; is arranged and firmly secured a gear-wheeh'b; which may mesh'into the teethf of agent-wheel, c, that is 'mounted on the shaft B, as shown in iig. 1;

'By means of a le'ver, D, which is pivoted to the frame A, and connected with a tread1e,'E, or some other." equivalent device, the. drum C can be thrown into gear. with the shaft.

To one fendo each drumr C',i s alsosecureda ring, d, which is' toothed on the face, as shown. F is a.

toothed segment pivoted toy the frame A, oppositev to the ringd, and connected with a slotted lever, 2, which caube raised vhy means of a' treadle, f, `or seine other equivalent device.

0n the end of the armF, on gue side of the toothed -Part of the saaie, is hung a smallfirictionolly,

as shown. v

"I he operation 'is ais-follows: The rope to which the dredge isattached is secured tothe drum C. When the rope is 'tob e wound around the drum,- the segment F israised by means of the lever`e,lso tl1`at when, then, the drum is pushed4 towards it and the gear-wheel c, by means o f the treadle E, the teeth of the ring Adwill mesh int'o thoseof the segment, while, at' the same time, the wheels 6 and c lwill gear together.

When thefc'rank a is turned, the drum C will also be turned, and the segment 'will rest against the end of the drum, being raised by every tooth of the ringd, andthenagain falling, of its'own weight,.into the space' be'tweentwo teeth. The arm c being slotted, falls as soon as the segment'has been brought into position, and. does not have its weight upon the segment.- All the parts are then in the position shown iu iig. 3 ofA the drawing.

, Should the dredge strike against an article, the. strain on the rope will at once draw the drum oil' the wheel c, and .will thereby disegage the drum fromv the shaft, so that the rope may unwind 'without affecting in thc least the motion of the shaft. t

While the drum is thus drawn back, the segment falls down, u ntil the pin h, which tits through tho slot in the rod e, reaches the lower end of that slot, asin iig. 4.. The roller g will thon, with its odge, touch the end of the drum C, and will Vinrrevolved 'by ,the same, thus not hindering its motion, but the` drum F will, in this position, prevent the drum from sliding towards the wheel c, and from becoming thereby connected with the shaft B.

The object of the arm Fis, therefore, to form a stop for keeping the shaft and drum outl of goor, when the I rope is unwinding, so that no accident can occur by the crank revolving.

I claim as new, and desire to secure by Letters Patentv 1. An oyster-Winding apparatus, cousstingof the shaft B, sliding drum C, gear-wheels bre, and d, and pvoted segment F, all made anti operating substantially as and for Vthe purpose herein shown and described.

2. Tlicilrum C, whenvarrangcd so that it can turn antl`slido on the shaft B, and when combined with the gears b t", and withl tho'lever D, all made and operating substantially asset forth. n

3. The block F, when pivotod to the frame A, and when provided with the friction-roller g,'as set toi-th.

4. The slotted bar e, for elevating tho block F,'in combination with the same, and with the drum C, all

made and operatingas set forth. v SAMUEL S. SHAW.
