37. For Improvements in Excavating Machines; Martin Newman, Jr., Lanesborough, Susquehanna county, Pennsylvania, November 19.

"The nature of my invention consists in a rotating cylinder or drum, hung in suitable frame work, so constructed that it can be elevated or depressed, or moved in either direction sideways; the cylinder is driven in either direction by a band or chain from a pulley actuated by suitable mechanism; attached to the band or chain is the bucket or scoop which digs out and carries away the earth; this is provided with wheels, and while it is not upon the drum, runs up on a railway on the frame, but when it comes in contact with the drum, it has a motion in a circular direction, and at that time it is intended to perform its operation, being returned along the railway when full by reversing the motion of the band or chain until it reaches the back of the frame, when the bottom is caused to fall or open and discharge the dirt."

Claim. "What I claim as my invention, is, 1st, operating the bucket by giving motion to the band or chain, and to the drum in one direction to fill the bucket, and then reversing its motion so as to draw back the bucket to be emptied, in the manner substan、 tially as herein described.

"2d, I claim the manner substantially as herein described of closing the bottom or trap of the bucket by means of the spring or incline, over which it passes in its forward passage."

38. For an Improvement in Pessaries; Jonathan Hovey Robinson, Charlestown, Middlesex county, Massachusetts, November 19.

"Although I have described particular mechanism as applied to the frame, for raising the strip of metal high enough above the bed die to admit of its being turned over as explained, I do not claim such mechanism in itself separate, or uncombined with the frame and machinery by which the strip of metal is progressively advanced towards the dies, but what I do claim is the combination of such raising mechanism with the machinery for imparting to the strip of metal its progressive forward movements as specified; the mechanism so combined with the said machinery, being the bale, the rod, the lever or arm, the crank, shaft, drum, belts, and the arins l', m', of the lever beam; the whole being arranged, and made to operate together substantially as specified.

"And I further claim, in combination with the mechanism which produces the progressive advancing movements of the strip of metal towards and between the cutters, the mechanism for producing the retrograde movement of the pincers, after the strip of metal has been entirely operated upon by the cutters; such mechanism being the pulleys, the endless belt, the movable frame, and clutch, or their equivalent, the vertical rock shaft, and its arms, the cams, the lifting bar, and its spring catch, together with the slide, and its projections, the whole being constructed and made to operate together essentially as specified. And I claim the combination of the arm 2,2 with the shaft w, and the mechanism for moving the clutch, the said arm being for the purpose of creating a retrograde movement of the clutch, so as to unclutch the pulley t,' from the shaft e, and this when the entire retrogradation of the nippers has been effected the same being accomplished as herein before specified.

"And in combination with the mechanism which produces the reciprocating rotary movements of the nippers or strip of metal held thereby, I claim the combination of mechanism for arresting or stopping such rotary motion immediately on the final retrogradation of the pincers taking place, such mechanism being the levers z,4 and n,3 the connecting rod p,3 arm g,3 shaft r,3 arm 8,3 spring catch y, as applied together and to the lever beam, and lifting bar y,2 as described.

44. For an Improvement in Ship Ventilators; Ralph Bulkley, City of New York, No

vember 26.

"The nature of my invention consists in providing ventilators with floatable valves to be acted upon by the water which casually rises in contact with the ventilation, whereby the air orifice of the ventilator becomes closed during the time the water remains in contact with it."

Claim "What I claim as my invention is, the combination of 'floatable valves' with ventilators for ventilating vessels and steamers, and the combination of 'floatable valve ventilators' with vessels and steamers. The valves to be acted upon, by the raising and the falling of the water when in contact with the ventilator. The rising water to cause the valve to close the air orifice and prevent the entrance of water, and the falling water to permit the valve to recede by its own gravitation, and thereby open the air orifice. The devices and operations of the same as herein described, for the objects and purposes herein set forth."

45. For an Improvement in Gang Ploughs; Henry Cowing, New Orleans, Louisiana, November 26.

"The object of my invention is to furnish to the agriculturist a labor-saving machine, whereby steam may be profitably employed instead of manual labor or horse-power, in ordinary field operations, and elsewhere, especially in ploughing and cultivating land."

Claim. "I claim the inclined coulters, so arranged as to throw out the ploughs without breaking, when they meet with an obstruction, in the manner and for the purpose set forth.

Claim. "I claim the boxes, oscillating upon fixed points, and having the flat bar springs attached to them, in combination with the chains, and the regulating screw and nut; for giving a more free and easy motion to the picker staves, and for the more effectually controlling and graduating the amount of pick."

54. For a Combined Boiler, Cupola, and Grate; Loftis Wood, City of New York, November 26.

Claim. "What I claim therein as new is the boiler descending from the top to the bottom of the cupola in combination with the removable grate, the water contained in the boiler surrounding the heated iron and coals substantially as described.
