turnover/ Burrs MACHINE r01; CUTTING HOOPS- To ALL WHOM IT MAY CONCERN: H 7

Be it known that JOHN TIXOMPISO-N, of Rochester, in the county of Monroe, and State of New York, invented a new and useful Barrel-Hoop, and Machine for making the same; and I do hereby declare that the followin is a full clear and exact descri ti'on, thereof reference bein had to the accom an in drawin s (3 Y 7 7 43 D g 7 making a part of this specification, in which- Figure 1 is a plan or top vieiw of the machine.

Figure 2 is averticals'eetion taken in the plane indicated'by the red line 1) in fig. 1. v

Figure 3i s a transrersesection of a hoop.

Similar-"letters of'refercnee indicate corresponding parts in the several figures.

The nature of my invention consists, first, in a Vooden'hoop produced by being cut in a bevelled form from the edge of a plank or bolt, said hoop being cut by a lateral out of the knife across the edge of the plank; and,'second, in a machine'for cutting said hoop.

To enable others to make and use my invention, I will describe its construction and operation, first describing the machine.

The several letters A, in the drawings, representthe bed-frame of. the machine; 13, the sliding frame; G, the

self-adjusting restior cutting bed; D, the knife; E, the ratchet-wheel, which governs the changes in the position of the rest C; F is the driving-shaft, and G the connccting-rods. The bed-frame A may be made of wood or iron, as may also the reciprocating frame 13 and cutting-bed O. The frame A is provided with lugs, H, which clasp the sides of frame'B. The knife Dis made the. length of a hoop, or a little more, and its edge may be provided with one or more offsets, as'scen at (t, fig. 1, each section, however, being parallel to the rest G. The gauge-rest b may be made adjustable,vertically, by means of set-screws, shown by dotted lines at n, fig. 2,

passing through slots in the girt A and into the verticalplatep of the gauge. The object of this adjustment.

is to regulate the thickness of the hoops. The rest G, if made of wood, may be faced with a plate of iron at the lower edge toward the knife, in which'cnse this plate may project at each end into a. recess, 0, formed in each side rail of the frame B, and constitute the pivot on which the rest swings. The latter should be so hung as to just clear the knife while passing over it. The adjusting lever J of the rest is operated by the pins 0 in the ratchet-wheel E, which is hung to the arm K, the latter being fixed to the sliding frame B. The wheel is provided with eight hook-teeth, t, (or twice runny teeth-as there are pins, 0,) and the spring pawl (Z prevents it from turning one way, while the spring catch 7: which is fixed to the bcd-frn-ine, turns it one notch in the opposite-direction at every turn of the driving-shaft. The rest 0 is kept in its place by the buttons g, fig. 1, and the bolt or plank from which the hoops are'being out is pressed firmly against the rest by the springs s, which are fixed to the sliding frame B. The timber is first sawed into planks or boards corresponding in thickness to the desired width of the hoops. The bolts are then made by-outting the planks into hoop lengths: A bolt is then placed between the springs s and rest C and the brackets-1', with its lower edge resting upon the gauge b, and as the rest is driven to the left the knifc cuts one hoop from the belt at one stroke, but only one third its length at a time, which requires so much-less power than to out the whole length atoncc. Then the sliding frame returns the ends of the relieving bar it strike the lugs H just before the frame reaches its back ward stroke, thus forcing the springs s, to which the bar is fixed, away fromthebolt, and its own gravity carries it down upon the gauge. The next strobe relieves the bar and the springs again catch and hold the bolt during the next cut. While this adjustment of the bolt is being effected the wheel E is turned onc notch, causing the end of the lover J to fall from pin c to pin 0", thereby changing the positionof the rest, the top being thrown back from the position shown by the dotted lines J, fig, 2. This gives the bevel}? making one edge of the hoop thick and the other thin, as shown .in fig. 3, which conforms it to the shape of the barrel or cask. At the nextstroltc, the wheel E being turned one tooth more, the pin c is carried up and the end of the lever J with it, where the lotter is held until after the next cut is made, and the next adjustment of the wheel drops the lever to the next pin, and so on. If necessary, there may be a spring or weight attached to the lever J to keep it down upon the pins. The sides of the hoops produced'by this machine are perfectly smooth and ready for use in that respect, and the edges may be made smooth also, when desirable, by planing the lumber before it is cut up. The bolts may be soaked in water, orsteamed if desired, preparatory to cutting them, and after one is placed in' the machine no further attention is required until it is nearly cut up, when another may be supplied; and in the interim the operator may be feeding the hoops to a crimping-machine, or he may be asserting and packing them. The sawed hoop is by far the cheapest heretofore made, but while one hoop is being sawed a perfeet cutting machine working upon my plan will produce from txvcnty to thirty in a much more perfect condition as regards finish. They may be made of any=desirezl "width or thickness, end more or less bevelled to canform them to the bilge or swell of the barrel or cask. The red lines in fig. 3 indicate a remaining portion of the plank from which the hoops are being cut. I

What I claim as my invention, and desire to secure by Letters Patent, is 1. lhe combination of the irregular shaped knife D with the automatically adjusting rest C and adjustable gauge 11, as and for the purpose setforth. v

2. The employment of the knife D, constructed. with one or more offsets in itscutting'edge, as described and for the purpose set forth. I 3. The combination of the wheel E, the spring pawl d, and clutehf, or-their equivalents, with the rest C, as and for the purpose set forth. i

' 4. I claim as an improvement in the manlifact'ur'c of hoops the cutting of the hoop from" the edge of the plank by a ent' alternately in a bevel line and in a right line to the side of the plank or in alternate bevel lines.
