JOSEPH PRYOR, OF WENDRON, CORNWALL, BUILDER, for an improved threshing machine. Enrolment Office, July 28, 1841. This machine consists of a strong wooden frame standing on four legs, or otherwise supported in a substantial manner. An axle lying across the frame, and working in suitable bearings, has keyed on to it at one end a heavy fly-wheel, at the other a large spurwheel; outside of these wheels, at the two extremities of the axle, there are two winchhandles, by which the machine is worked by hand, or it may be driven by any other convenient mover. A second axis, lying parallel with the former and similarly mounted, carries a pinion which gears into the spurwheel before mentioned, and also a wooden drum, from the periphery of which project eight, or any other convenient number of angular iron beaters. This drum has a moveable case or covering over its upper cir cumference, with an opening in front, through which the grain is supplied to the machine from a feeding-table. Below the feeding-table there is a sliding rack, having a concave wooden surface corresponding to the outer circumference of the drum and beaters, upon which surface a series of angular iron plates are fixed; this rack slides backward and forward upon a bearer stepped into the frame of the machine, its distance from the drum being regulated by an adjusting screw, which works through a fixed nut in the cross rail. A rapid motion being communicated to the drum, and the corn fed in, it is carried down under the drum, and the seeds separated from the straw by the action of the beaters and the rack The claim is to the general arrangement and combination of parts, by which a new and improved mode of operating is introduced.

Mr. Oxley's Plan for a Steam Vessel.-Sir,-I have just been looking over the original drawings of the plan of the steam vessel I invented in 1807, and of which the description appears in No. 937 of your interesting journal of this day, and by comparing the two together, I find that in the original, the figure, No. 1, in your Magazine, is in mine called a side view, in which some parts are omitted to prevent confusion in the delineation, which parts appear in the other drawing; and I also find figure 2, in page 67, is called a bird's-eye-view, which is intended by me to show the manner of stopping the vessel, or reversing the motion thereof. Have the goodness to give this note a place in your next number (No. 938) which will render the description perfectly understood by all your readers. I remain, Mr. Editor, most respectfully, your very obedient servant, London, July 24, 1841. THOMAS OXLEY. LONDON: Edited, Printed, and Published by J. C. Robertson, at the Mechanics' Magazine Office, HOLLOWAY'S PATENT HEAD FOR OPEN CARRIAGES. In a recent number we inserted a notice, copied from a provincial paper, of a valuable improvement in Britzska-heads, patented by Mr. N. I. Holloway, and the patentee has enabled us this week to lay before our readers a full description of the peculiarities of his very ingenious contrivance. The subject is one of considerable interest, relating, as it does, to the improvement of a most important branch of our domestic manufactures. English pleasure carriages have long maintained an unrivalled celebrity throughout the world, and the improvements we are about to describe will add another feature to the numerous comforts and conveniences for which they are so pre-eminently distinguished. The advantages of the patent head are that when down, the entire head lies on the elbows of the hind seat like a half head (from which, without the closest scrutiny it cannot be distinguished,) and yet can be raised almost instantly, and form a closed carriage for four persons-as shown on our front page. It may be extended to enclose only two persons, when in addition to the shutter in front, it has side glasses, allowing a comfortable entrance and plenty of room inside, in which form it is shown on the opposite page. This head is applicable to all the various styles of light open vehicles now so much in use. It is composed of five round-cornered bows; the third, fourth, and fifth are secured by hinges and goosenecks to the top of the standing pillars; . the second has a dove-tailed catch and bolt on its extremities, to secure it when up, to the top of the front elbow rails, the ends of which stand over the door joints to receive the glasses; the first how is hinged to the second, and a German shutter arranged in it. The flap on the front seat falls behind the front elbow rail, and consequently passes through the first bow when the head is up, and only reaches far enough to receive the end of the German shutter. The doors are grooved for double glasses, which are either separate, drawn up, and placed one above the other; or they may be hinged together, and when drawn up, the inside glass is turned down and placed outside of the frame and doorrail. The bows are set with webbing in the usual manner, and covered with leathers similarly to a half head; the portion of leather between the second and third bows, extends only about 7 inches down the side of the head, the edge being squared with the second and third bows and webbed; a piece of good webbing extending from the second to the third bow, keeps this edge firm. The cloth head lining at the same point is finished on the edge with a piece of pasting lace; in all other respects it is finished like a half head. The tops of the glasses, when drawn up, pass between the leathers on the outside, and the cloth on the inside, requiring no rail to receive them. A pair of joints, extending from the second to the third bows, strike up that portion of the head, and may be placed either inside or outside; other joints extend the head between the hind elbow and the third bow, and between the first and second bow in the same manner. A leather curtain extending across the front, webbed at the corners, buttoning over the top and down the sides of the front bow and along the front elbow rails, closes that portion of the head when the carriage is required for four persons: this curtain may be secured to the top of the front flap and folded up when not in use, or it may be entirely removed or placed in a box under the coachman or footman's seat. To secure the second and third bows firmly together when the head is down, a notched pin extends from the back of the second bow some 7 or 8 inches from its ends, and a corresponding plate is secured to the front of the third bow. Suppose the head up, and it is required to be put down: after removing the curtain, or folding up the German shutter, and dropping the glasses into the doors, unbolt the locks or second bow loosen the joint between the second and third bow-lift the first and second bows across the door when the leather will fall between the second and third bows; in the same manner, insert the |
