To ALLfwHoM. rr MAY coNcnRN'z Be it known that I, ALBERT McALrINE, of Pittston, in the county of Luzerne, and State of Pennsylvania, have invented new and useful Improvements in Machines for Cutting or Shaving Hoops for Barrels, Casks, Btc.; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification.-

'lhe machine embraced. in the present invention consists of, a revolving wheel made ofv a circular `elliptic shape around its periphery or edge, where it is provided with a series of similar-shaped knives or cutter-blades secured to the outer periphery of said Wheel at equal distances apart, arranged with a head-block located directly opposite the revolving cutter-wheel, adjusted by set-screws so as to permit the hooptc passat any thickness required and to be out or shaved concave so as to t the shapezof `the cask or barrel. In connection with the above, I have also arranged a feed and a pressure-roller, in such a manner as to draw the stuff being cut, through the machine'as `fast as acted uponv by the revolving cutter-wheel, leaving the uncut part of the hoop in the hand of the operator, perfectly under his control, so that however winding or crooked the pole may be, it i's cut an even thickness in all its parts and in such manner so as not to disturb the bark on said hoop only so far as may be required to reduce the hoop to an even thickness. In the accompanying plate of drawings my improvements in machines for shaving hoops are illustrated- Figure 1 being an elevation of the front side of the machine; and

Figure i?, a plan or-top view of the same.

Similar letters of reference indicate like parts.

A, in `the drawings, represents the framework of the machine, which may be of .any suitable construction t-o accommodate the'varions working parts of the same. B a wheel or plate, having its edge or periphery C made of a circular elliptic shape, and provided with a series of cutter-blades, D, at equal distances apart and of a corresponding shape thereto. This wheel B is secured in a vertical position to one end of a horizontal shaft, E, arranged to turn in suitable bearings of the upper cross-pieces F, of the framework A.' G a pulley on shaft E, to whichthe driving power used is to be connected in any suitable manner for driving said shaft E and thus revolving the cutter-wheel B. I-I a head-block, secured by means of set-screws II to the framework A, ina vertical position, and directly infront of the wheel B, between the round edge H2 of which Nand the saidblock I-I is an opening or space, K, the width of which is to be adjusted to the thickness of hoop that it lis desired to shave inthe machine. To shave a hoop in the machine, the pole from which it is to be shaved is first inserted in the same between the head-blcck H and the wheel B. When revolving the latter, its cutters successively act upon the saidstick cutting it across the grain in-to a thickness corresponding to the width of the space between the head-block and the cutter-wheel, for the whole or only a portion of its length, as it is fed through and between said head-block and the cutter-wheel, by the hands or in any other suitable manner. To feed the stick through the machine, I have provided an arrangement of a feed and a pressure-roller to be now described.

L the feed-rollenplaced in a vertical position back of the cutter-wheel, so" as to bear' upon the cut side of the hoop as it passes from the cutter-wheel. This feed-roller isiiluted or corrugated in the direction of' its length, and is secured to the upper end of a vertical shaft, IWI, arranged to turn in suitable bearings of the framework A. N a horizontal bevel gear-wheel, secured to shaft M, at or near its lower end, with which gear-wheel a vertical bevel gear-wheel, O, engages; which is attached t'o one end of a horizontal shaft, P, arranged to turn in bearings of theframework A, and connected through pulleys Q, R, and B2, and belts S and T, with the shaft carrying cutter-wheel B. U the nessure-roller, hung through similar spring-arms V, one at each end, to the framework A, so as to stand in a vertical position to one side of the feed-roller back ofthe head-block; the pressure-rollers being arranged lto revolve in the said spring-arms. W Aset-screws, in framework upon the inside of the spring-arms V, the object Vof' which is to so hold the spring-arms as to preventv the pressure-roller from running in contact with the feed-rollenwhen no stuff is passing between the two.

From the above description the operation of the feed and pressure-rollers in connection with the cuttingwheel is plainly obvious, as 'by'the manner in which the pressure-roller is hung, it is capable of holding the hoop' tight between it and the feed-roller, as it passes from the cutter-wheel, whether such hoop be more or less thick. In conclusion, it may be here` remarked, that, from the manner in which the stuff' passs to the cutter- Wheel, and from the factthat it is cut by the edge of the Same and through convex-shape cutters, in the direction of their length, it is plainly obvious that the stick While beingcut is under the perfect control of the operator and workman, so thatitfcan be turned either to the right or left as may he found necessary in order to cut the stick to the best possible advantage for securing the greatest amount of strength in the hoop, as, for instance, to cut out this or thahknot or haw, as it or they may occur in the stick.

. What I claim as new, and desire to secure by Letters Patent, is

Dressing barrel hoops their entire length to a thickness by the cutterwheel B, when arranged to operate with the guide or head-block H, pressure-roller U, and feed-roller L, all constructed substantially as described.

The above specification of nay invention signed by me this 6th day of November, 1866. l
