14. For an improvement in the machine for Cutting Crackers, &c.; John Johnson, and Otis Freeman, Boston, Massachusetts, May 17. Claim. "We shall claim causing the cutter frame with the cutters, after the impression has been given upon the dough, to move away from the inclined bed, or apron, over the bed, and leave the scraps and waste dough upon the apron, or bed, and to drop the crackers, or biscuits, upon a shelf, or other suitable receptacle separate from the apron, or bed, all in the manner as above set forth; the said shelf, cutters and apron being constructed and operating substantially as set forth; also the mechanism by which the cutter frame is operated and turned from a horizontal position to an inclined one, the same consisting of the curved bar, and horizontal bar, in combination with the mechanism which draws the cutter frame towards the inclined apron, or bed; the whole being constructed and arranged as set forth."

15. For an improvement in the Washer, for cleansing Satinets and Woolen Cloths; William Soule, Stafford, Tolland county, Connecticut, May 17.

This is for an alleged improvement on the washer, which consists of two rollers; the box in which the rollers work is divided into two compartments, an upper and a lower one, by a partition perforated with holes, for the passage of the cloth, and others provided with valves to retain the suds in the upper, or permit it to descend into the lower chamber.

Claim. "What I claim as my invention, is the application of the partition and valves for the upper suds chamber, with the cocks for drawing off the suds, when retained in the upper chamber, to the washer described and set forth."

16. For an improvement in the Cooking Range; Herbert H. Stimpson, Boston, Massachusetts, May 17.

Claim. "I do not claim the introduction of the smoke, heat, or other volatile products of combustion, to the sides of an oven of a cooking range through lateral flues proceeding from the boiling chambers, or space under the boilers; but that which I do claim consists in the manner of arranging the flues which proceed from the boiling chamber and fire place, and pass in contact with the oven, so as to equally, or thoroughly, distribute the heat over the exterior of the oven, and permit the operations of baking and boiling, to be carried on without shutting off, or interrupting, the communication between the fire place and flue space beneath the oven, and around its sides; the said arrangement consisting in carrying the lateral flues, or those proceeding from the boiling chambers, directly against the front parts, or halves, of the sides of the oven, and thence horizontally over, and in contact with, the top thereof, and opening the same at the top of

the oven into the discharge flues, as described, in combination with carrying the main discharge flue of the fire place beneath, and in contact with the oven, and around and in contact with the rear parts, or halves, of its sides and top, the same being connected with the discharge flue leading to the chimney, and the whole being substantially as set forth."

17. For an improvement in the Smut Machine for cleaning Wheat, &c.; Henry B. James, Mount Holly, Burlington county, New Jersey, May 17.

This machine is a modification of that class of smut machines which have been extensively used, and which, therefore, have been the prolific source of improvements, or modifications, and hence of patents. It consists of a set of beaters, or fans, on a vertical shaft within a case, through which the grain passes to receive the action of the beaters, or fans, and of an upward current of air produced by the action of the fans. In this instance, the case is conical, and fluted on the inside, and the beaters, or fans, are constructed in a manner fully expressed in the subjoined claim. The top of the case is provided with a spiral flue, or trunk, through which the grain passes into the machine, and where it is acted upon by the current of air before it reaches the beaters, or fans.

Claim. "What I claim as my invention, is the arrangement of the circular trunk, as described, to conduct the air, and float out foreign matter from the machine, and the fans constructed of two, or more, sets of leaves, or plates, arranged one above another on a common shaft, said plates being placed diagonally upon said shaft, and arranged so that the leaves of one tier shall break joints with those above them, to act upon the grain, in combination with a stationary inverted cone, roughened on the inner surface by slight flues, or otherwise, and to produce a current of air through the machine, as described."

18. For a Harrow, or Sward Cutter; Dennis Rice, Rowe, Franklin county, Massachusetts, May 17.

The teeth of this harrow are arranged in the usual manner, in a triangular frame, but, instead of being straight and pointed, they are bent back in a segment of a circle, with the front edge sharp, to cut the sward.

Claim. "What I claim is the mode described of constructing the sward cutter harrow; that is to say, by using and combining with the harrow frame a suitable number of movable harrow teeth of the above description, for the purpose specified."

19. For a Revolving Rule, for measuring surfaces, and particularly applicable to lumber; Charles Ross, Piqua, Miamia county, Ohio, May 17.

A wheel, of one foot in circumference, is so arranged in a case, as to have a portion of its periphery project beyond the case, and a por

tion of its face visible through a hole, the edge of which is graduated to correspond with concentric circles on the face of the wheel, graduated in the manner of the common lumber rule. The shaft of this wheel is geared with the shaft of a cylinder, so that the latter will make one revolution to thirty-six of the former, there being thirty-six divisions to indicate the number of revolutions made by the wheel; and the shaft of this cylinder is geared with another cylinder, which makes twelve revolutions to one, to mark the number of revolutions made by the first cylinder. The scales on the wheel and cylinders are so arranged as to give the superficial as well as the running


Claim. "What I claim as my invention, is the combination of the common board rule with the self-calculating cylinders, and their combined application to the measurement of plane surfaces in general, but more particularly to the measurement of the superficial contents of boards, plank, and lumber."

20. For an improvement in Lamps; Henry B. Fernald, Boston, Massachusetts, May 17.

In this lamp there is an annular distributing reservoir some distance above, and communicating with the burner by a tube, (designated in the following claim by the letter a,) and by another tube (b,) with a hand pump, in a main reservoir in the pedestal of the lamp, by which the oil is forced up into the distributing reservoir. There is another tube to discharge the surplus oil from the distributing reservoir, and the tube (a) that supplies the burner, into the main reservoir-the tube (b,) for these purposes, extending to the upper level of the distributing reservoir, and communicating by a hole with the tube (a)at, or near, the level of the burner.

Claim. "I claim the apparatus added to, and combined with, the burner, and the main reservoir, for the purpose of maintaining the oil in the wick case at a constant level, with respect to the wick; the same consisting of the distributing fountain, and tubes (a and b) proceeding therefrom, and opening into, or communicating with, each other, (at the level, or about the level, of the top of the burner,) and with the column, or reservoir, as before set forth; the whole being arranged and operating in connection with the burner and fountain beneath the same, substantially as specified."

21. For an improvement in the Smut Machine for cleaning Grain ; Abraham Straub, Milton, Northumberland county, Pennsylvania, May 17.

"The nature of this invention consists in forming an involuted conductor for the grain, from the centre to the periphery, under the fan upon the runner, at which point it is subjected to the action of the beaters, and wind from the fan at the same time, and is cleaned of all the loose dirt and smut as fast as it is broken.

Claim. "What I claim as my invention, is constructing the runner in the manner set forth, having involuted conductors on it, intersected

at the periphery by beaters, and surmounted by a fan; the whole being arranged substantially in the manner and for the purpose specified."

22. For a machine for Trimming the ends of Bristles in making Brushes; Samuel Taylor, East Cambridge, Middlesex county, Massachusetts, May 17.

The brush to be trimmed is placed on two guide rails made adjustable, to regulate the length of the bristles; and below this is a plate with V shaped teeth, made sharp at the sides, and below this, and in contact with it, there is a rotating cutter, which acts in connexion with the teeth, in the manner of shears, to cut the surplus length of the bristles.

Claim. "I claim the apparatus, or means, of receiving and holding the bristles to be cut, (the same consisting in a series of teeth, &c., extending from a plate, and having their edges, or sides, sharpened as described,) in combination with one, or more, revolving, or movable, cutters placed directly beneath the said teeth, and arranged and caused to pass in contact, or nearly so, with them, so as to act in connexion therewith, similar to scissors, or shears, and cut, or separate, those parts of the bristles extending below the teeth from the remainder, or parts above them, and thereby reduce all the bristles of the brush as set forth; and I also claim the combination, with the above, of the mechanism for holding, or guiding, the block, or brush, or presenting the bristles to the cutters and teeth, in such manner as to cause them to reduce, or cut, the said bristles to a regular, or requisite, length; the said mechanism consisting of the adjustable rails, or guide bars, arranged over the cutters and teeth, and in connexion therewith substantially as described."

23. For an improvement in Awnings for the front of shops, &c.; John Sebo, Wilmington, Delaware, May 25.

This awning is attached, by its upper end, to a roller having its bearings in staples attached to the house, and its other end to a pole, and from this pole a set of sustaining cords extend over the awning around the roller next the house under the awning, and thence around a roller on posts at the edge of the walk; and below this, and revolving with the same velocity, there is another roller, on which wind another set of cords. The first set of cords not only sustain the awning, but, by winding on the roller at the top of the posts, answer the purpose of rolling it up on the roller next the house, whilst the second set of cords unroll it-the two sets rolling and unrolling on the two rollers, which have for this purpose equal velocities.

Claim. "What I claim as my invention, is sustaining the roller, next the house, by means of a cord passing over pulleys, and winding up with the cloth, conducted in the manner and for the purpose set forth; I also claim, in combination with the awning, the rollers, one for the awning, and the other for the sustaining cords, as described."

24. For an improvement in Oil Boxes for preventing journals from heating; Elisha Reid, Columbus, Georgia, May 25.

Claim. "What I claim as my invention, is the prevention of heating journals and boxes, by surrounding the boxes with a reservoir of water, in such manner as to prevent the access of water to the oil box and journals, as described, thereby preventing heat, and, consequently, the drying away of oil, and wear of the rubbing surfaces, and the necessity of frequent oiling, using for the reservoir any material suitable, and any composition of metal for the bearings."

25. For an improvement in the process of Converting Iron into Steel; Simeon Broadmeadow, New York City, May 25.

The patentee says, "My improvement consists in the using of a permanent roof of fire stone, or fire brick, in place of the temporary covering heretofore employed. I also use a sliding shutter, which is placed in front of the furnace, so that it may be brought down as required. My improvement in the manufacturing of the steel, after the process of cementation has been completed, consists in the taking of the bars first from the upper part of the convertory, whilst they are at the highest temperature to which they are to be brought, and subjecting them immediately to the action of tilting, or of rolling, without the necessity of reheating. To do this, a part of the upper layer of bricks, which enclose the converting oven, is first removed, so as to enable oue to draw out the upper bars, and as the bars are successively operated upon, the bricks are further removed, until the whole contents of the convertory have been tilted, or rolled. As this process goes on, the sliding shutter is brought down, so as to enclose the part from which the bricks have been removed. By this procedure several advantages are attained in the process of manufacturing steel. Under that hitherto followed, the whole charge has been allowed to cool down before removing the steel from the convertory, and this necessarily resulted in great loss of time; the bars after being removed, had to be reheated, in order to their being tilted, or rolled: by this reheating time was consumed, and the steel actually injured, it being a well established fact, that every time steel is highly heated it is deteriorated."

Claim. "What I claim as new, is the improvement herein described, of taking the steel from the oven in its heated state, and subjecting it to the action of rollers, or of the tilt hammer, without the necessity of reheating the bars; by which improvement said manufacture is greatly facilitated, and the quality of the steel much improved."

26. For improvements in the Engine, to be actuated by Inflammable Gas, or Vapor; Stuart Perry, New Port, Herkimer county, New York, May 25.

"In my inflammable gas, or vapor, engine," says the patentee, "the power which is to be obtained from it for the driving of ma
