IMPROVED MOiDB OI" FILLING MARSHES.

TO ALL WHOM IT MAY CONCERN;

p Be it known that I, GEORGE HOWELL, of the city and county or, Philofleiphia, and State of Pennsylvania, have invented a new and improvedMode of Filling Marshes, 85o.; and I do hereby declare that the folloviing is afnll and exact description thereof, reference being had to the accompanying drawings and to the letters oi' reference marked thereon.

My invention is :in improvementon my mode of filling marshes, A35e., patented November 12, 1857, und

inninly consists, iirst, in anV excavating and pumping-apparatus, combined 'with o. scoxv or boot, beneuth which it is plnced for iheremovel of the mud oreorth from the hed o the river or other sheet of water; the'saidieppzr rntus being submerged and elevated et pleasure by means ot' vertical screws operated by ineens of ageored connection with a driving-shaft of esteem-engine. In the second place, the improvement consists in o. novel mode of detcrminingthc'proper depth to submerge the apparatus; und, in the third place, in a mode of holding it in its oltitudinol position. The construction and arrangement of the appara-tus will be understood hy the following description. In the accompanying drnwings, which make a part of this specification- Figui-e1 is alplon of the apparatus, in combination with a. scow.

'Figure 2 is a side elevation of the same.

Figure 3 is a. view of the excavating-caso A from beneath.

Figure 4 isv on end view of one of the shafts B, providednith stirrers C.

Figure 5 is e side view of one of the gripes W.

Figure 6 is an isometrical view of the gauge S.

Figure 7 is afvievv of the geared lever Q, and parts in connection.

Figure 8 is a front view of the same.

Likeletters in all the iigur'es indicate'the same parts.

A is o. cose, containing o series of revolving shztftsB, which are provided with stirrers C for loosening the mud or earth und mixing it Vwiththe water it underlies, so as 'to bring it to the proper consistency to be sucked up and removed by the pump D, which is secured to the suction-pipe E. Spid pipe has n nnge, a, which is bolted to the upper suri'ace of the cose A,-so as to rise and follwith it in its adjustment. The shoi'ts B have wheels b, which gear intoI the pinions c on'the longitudinal .shaft F, and themotion is given to said shaft by means of its connections with the vertical shuft G, there being 'o bevel-pinion, el, on the lower end of saidshoft. There is a pinion, d1, on the upper'end of the shaft, which gears into the wheelv e, on one end-of4 the shaft H,

whichpasses through the body of the pump D, and has on its other end a. spur- Wheel-,f, which gears into the.

pinion f -on the short shaft H'.. The said shaft has n connection with the counter-shaft I in the frame J, by means of the belt g and pulleys 7i z.

' The counter-shaft is driven by the shaft K of the engine, which in practice is placed on boardV thc s-coiv A', there beingra pulley, z', on the shaft K, und i on the counter-shaft I, cpnnectedy bythe belt j.

The pump is rotated by means of the belt k, which connects the pulleylof pump and Z' ofthe counter-shai`t. The framed', which supports the counter-shaft', .turns partially onthe drivingshoi't Krto provide forltighL ening the belts, there being coupling-rods M and M', connecting witlr scour A and frame J, as seen iu iig. 1; The case A is submerged and elevated by means of the vertical screnwrods N, whichore connected with it :xt their loner ends, as seen in iig. f?. The upper ends of the rods are provided with bevel-Wheels o, that Ageur into the pinions o. on the shafts O, O1, and O zfsothet by turning one of said shafts the same motion is 'given to thefour vertical screw-rodsN, which motion is`given by mea-ns of the beltPfpulley q, on the driving-shaft, and q on the short shaft L, on the shifting-lever Q, and upright projection r, on one Voi' the pedestuls R. On the other end of said shaft L there is a spur-pinion, s, which geors' into the pinions s* :ind e? on-the pronged end of the lever. When the screw-rods N are not to be opernted,"the lever is in the position seen in figs. 7 and' 8, sheet No. 2, which. keeps both of the pinions s and e2 out of gear with thc'wheel t on the shaft-O1; but when motion is to be gvento the rods, for the elevation or depression oi the case A, one ofthe pini'onsfis brought into gear with the wheel. The reverse motion is given by reversing the lever. 'There is a milled heed, u,for

fastening the lever against the projection r of the pedestal R, the screw-stem v of the head playing in the eccentric slot w of the projection. i

The scow has an opening in its bottom large enoughto receive the ease A when in shallow water. There is a gauge-rod, S, which is provided with a. foot, S', that sinks into the mud and determines the depth, slightly yresting on the end of the screw-rod N when the case is submerged the proper depth.

There are chains T 'l over the pulleys UU inthe standards V V, 'which are provided with weights :c to keep them tight. The lower ends ofthe chains branch oif to each side of the case A, and are fastened thereto. Whcn the case is at its proper depth, the gripes WNV-are drawn inwards in the standards by means of hand-wheels X X v on the screw-Shanks of the gripes to' confine the chain against the standards,pand thus secure said case in its position.

The stirrcrs C are made of Hat springs of steel, as represented in figs. 3 and 4, and have a bent form, so as to cause them to readily spring when they strike any unyielding object, to keep them from breaking. Otherwise the construction'and arrangement of the stirrersare the same as represented in my patent, dated November 12, 1867.

l` attach a hose or tube to the flange y ot'A the pump l) for-` conveying the mud to its destination.

'.lhere arelinks Y, Y, and Y2, which connect the case A and Vscow A at side to give a parallel motion und firmness to thc-former, to take the strain oil' the rodN. There are also guiding vertical rods Z Z, the lower ends of which are secured to each end of the case, and their upper ends pass through the scow, as seen in figs. 1 and 2. 4

It will be seen that when the case is loweredgto its proper depth, and the stirrer-shafts are revolved rapidly by means of their connection witlrthe driving-shaft'K, through the gearing above described, the mud and Water become thoroughly mixed, andare sucked up .by the pump D and forced through the hoseor tube.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The combination and arrangement of the case A with a scow or boat by means of the vertical serewrods N, wheels o, pinions o', and`shafts O, O, and O2, the said parts being arranged and operating substantially as described. y

2. '.Lhc combinatioirof the links Y,Y, and Yz with the case A and scow A', for giving a parallel motion to lthe'former, substantially as described.

3. The combination of the vertical rods Z Z with the case Aand scow A', substantially as described.

4. The geared shifting-lever Q, arranged and operating in relation to the driving-shaft K and shaft O, substantiallyin the manner and for the purpose specified.

5. The combination of the chains Tpulleys U, standards V, and gripes W, with the case A and scow A', for 'holding the case in its altitudinal position, substantially as described.

6. The combination of the coupling-rods M and M' with the case A and'scow A', substantially as described and for the purpose specified.

'In testimony whereoil have hereunto Iset my hand and aixed my seal, this 17th day of February, 1868. I GEORGE HOWELL.- [1.. 5.] Witnesses:
