Y. SINGLETON. No. 4536. What we claim as our invention, and desire to secure by letters patent, is the manner in which we lay out and form the two straight sides of the buckets we use on our improved wheel, to wit: the extreme points of the buckets being placed at the distance of thirty degrees, or thereabout, from each other, their two straight sides meeting at an angle of twenty degrees, or thereabout, and their rear sides being at an angle of thirty degrees with the radius of the wheel, as laid out according to the directions, substantially as herein set forth. FREDERICK P. HAWILAND. EBENEZER TUTTLE. No. 4537. I am aware that one division of mails, carrying one color or set of colors, have been connected with two trap-boards, by having two sets of trap. boards one above the other, requiring separate and distinct movements to operate them, thus rendering the machinery more complex and expensive; and therefore I wish it to be distinctly understood that I do not claim as my invention simply connecting one division of mails carrying one color or set of colors; but what I do claim as my invention, and desire to secure by letters patent, is connecting each division of mails with two divisions of tail cords, as herein described, whereby I am enabled to use but one card for each lash of any number of picks, as described. And I also claim as my invention connecting, by means of horizontal slides, all the trap-boards with one vertically sliding frame, as herein described, whereby all the trap-boards are operated by one lever, as herein described. JOHN, PERRINS. - No. 4538. Having thus fully described the manner in which I construct and arrange my apparatus for the opening and closing of the valves of registers for air-heating furnaces, what I claim therein as new, and desire to secure by letters patent, is the manner herein set forth of employing a hemispherical body, furnished with volute-formed openings or threads, which receive and operate upon pins extending from the middles of the valves adapted thereto ; the whole combination and arrangement, and the consequent operation of the parts, being substantially the same with that herein fully In testimony whereof, I have hereto set my signature, this fourteenth day of February, A. D. 1846. HENRY F. BAKER. No. 4547. Having thus fully described the manner in which we construct and operate our improved excavating machine, what we claim therein as new, and desire to secure by letters patent, is the manner herein described in which we have connected and combined the scraper-staff, or arm, with the machine, so that it may be raised or lowered by means of the racks and pinions, (by the aid of the triangular piece.) arranged and operating as set forth ; thereby dispensing entirely with the hollow mast, and with the toothed gearing and chains combined with said mast, as used for that purpose in the original machine of Otis. DANIEL CARMICHAEL. JASON C. OSGooD. , No. 4548. What I claim as my invention in the above named machine, and desire to secure by letters patent, is— First. The method of arranging screw-blanks and all other similar articles and regularly delivering them by means of two inclined rollers, substantially as described, whereby the rollers, by their inclination and rotation, cause the screw-blanks thrown into the hopper promiscuously at the up-. per end to arrange themselves with the shanks hanging in the space between the rollers and the heads resting on their peripheries, and thus gradually to descend towards the delivering end; and this I claim whether both or only one of the rollers be made to rotate, or whether the rollers constitute the bottom only or the entire hopper. - Second. I claim the delivery slide in combination with the tube or any analogous device, into which the blank or other similar article is discharged, substantially as described, whereby the blanks received from a hopper or other feeder are delivered in a vertical position into a conveyor, and the further delivery from the hopper is checked until a repetition of the operation is required, as described. Third. I claim so operating the fingers as to receive the blanks, &c., in a vertical and change them to a horizontal position, and move them forward to introduce them in the gripers, substantially as herein described. Fourth. I claim the gripers in combination with the sliding spring turn screw, substantially as herein described, by means of which combination the blank is prevented from turning by the turn screw in the nick, the gripers simply holding it steady and in such a central position without defacing the head and shank, and by which also the turn screw is made to enter the nick irrespective of its direction when the blank is introduced as described. Fifth. I claim governing the motions of the chaser towards and from the axis of the blank, by combining the chaser-head with a carriage and sway-bar moved by a cam, substantially as described. And I also claim connecting one end of the sway-bar with an adjusting slide, when this Doc. No. 52. 257 is the combination of the two side flues D, with the vertical flues of the elevated oven, as represented in the accompanying drawings at D, figure 1, and DD, figure 2, and set forth in the foregoing description. - JOHN B.T. CLUTE. No. 4544. What I claim as my invention, and desire to secure by letters patent, is making one arm of the cleviee to extend back to within reach of the person who holds the plough, to which arm a regulator is attached for goverming and securing the same, and thus giving any desired pitch to the plough without stopping or checking the team; using for the construction of the same the most proper, cheap, and durable material which will produce the intended effect. CHARLES L. MEECH. - No. 4545. What I claim as my invention, and desire to secure by letters patent, is the application of a flexible hoop, ring, or band 1, to an opening 8, communicating with a hollow or chamber 2, in the rim of a wheel A, in such a manner as to close the opening 8 in a part of its circumference and leaving it open in the remainder, thereby allowing a communication with the chamber 2, upon one side of the wheel A, while the opposite side is closed, and the moving agent confined in such a manner that its power is expended directly and constantly upon the periphery of the wheel A. The said hoop or band 1 may be made of any flexible substance; may be made of any convenient form; may be made continuous, or jointed, or a part only of the hoop or ring 1; may be used and applied to the opening 8, in the same manner as a portion of the continuous hoop or ring 1, above described. 2. The hoop or ring 1 may be applied to either side of the chamber 2, in such manner as to produce the desired effect, operating as a circular valve. RICHARD FIELD STEVENS, M.D. No. 4546. ! What I claim and desire to secure by letters patent is one or more reverberating chambers, (made and arranged as above set forth,) in combination with the fireplace and boiler; the same being made to revolve and retain the volatile products underneath the boiler long enough to be consumed thereunder, as above explained. And I also claim the manner of arranging the air distributing boxes, with respect to the bottom of the boiler, in combination with the curved deflecting bottoms of their respective chambers, in order that the flame produced by combustion of the volatile gases, or other matters passing over the perforated plates of said air-boxes, may be blown in jets against the bottom of the boiler, as set forth ; the said mode of arranging the said air-boxes consisting in giving each of them an inelined position, substantially as represented in the drawings; and as above specified. - - :... :: * * In testimony whereof, I have hereto set my signature, this fourteenth day of February, A.
