Goonnrcn, of the city of Joliet, in the county of Will, and State of Illinois, have invented certain new and useful Improvements in Machinery for the Manufacture of Clay Pipes; and we do hereby declare that the following is a'full, clear, and exact description thereof, reference being had tothe accompanying drawings, making a part of this specification, in whichv Figure 1 is a transverse section. ' Figure 2, an end view of the shaft and propelling-screw or beater. Figure '3, a side view of the heals supporting the cutting-disk. Figure 4 a top view of the same.

Like letters refer to the same partsin all of the figures. The nature and object of our` invention consist in constructing a machine for the manufacture of clay pipe with'a horizontal tempering-mill, and a vertical tempering and expelling-mill, so'as to temper the clay properly without taking it to a high elevation, and render the machinery more compact; in the construction and Ylocation of a disk, to be supplied with cutters, so that when cutting it will descend with the same motion as the pipe, to produce an even and square out, andcut a large Vor e'ven'small pipe into desired lengths or sections, while the pipe is continuously made in a vertical position; in suspending such disk or wheel by weightedguides, adjusted with or to act in unison with the weights which support the pipe in the peculiar -construction of the knife or cutter, so that it can'be operated by stationary cams or inclines; in providing the guides with double-acting cams or inclinesythe arrangement of weights andl rests so that the weights Vwill increase in number on a single cord as the weight of the pipe increases; and in the several new combinations' hereinafter set forth and claimed. To'enable others skilled in the Vart to make and use our invention and improved machinery, we will proceed to describe its construction and operation. y The cylinders B and C are supported by a frame, A, constructed in any-convenient manner. The cylinder B is made of iron or other suitable material, and is about six feet in length, and in diameter tapers from three to two and one-half feet. .Thecylinder, or temperer and ejector C, is of the same diameter, and extends below B suiiiciently to allow the' dies' to have their upper extremities located jest below the lower internal line of B. Inside of the cylinder B abeater is placed, the shaft E of which is provided witharms or knives a, which temper the clay and at the same time carry it forward to C, by reason of the incline of their faces, they being set at an angle as shown; The shaft E is supported at the outer end by the head ofthe cylinder, and at the inner by the cross-bar The inner end of the shaft 4is provided with a. beater, F, cut into two parts, each being carried and setatl an angle with the shaft, substantially as shown in iig. 2. A shaft, N, which passes through a hollow shaft, 0, with a similarbeater, d', is placed in the cylinder C.' The hollow shaft O is also supplied with a series lof similar plates d d, so arranged in their curves and angles as to assist vin tempering the clay and force it downwards.A AThey rotate in a direction opposite to the beater d, s'o as to prevent as much as possible the rotating ofthe pipe as it is forced through the dies, which object is also `aided by having the beater d so locatedthat the principalportion of its operation is above the lower internal line of the cylinder B. Cylinder C may be operated by a single shaft, but not as well. '.l'othe'se shafts O and N are attached at the upper ends mitrewheels M and L, which are operated by the mitrewheels J land-K on the shaft I, from which shaft a rotary motion is given to the shaft E by means of the pulleys G H and belt c. At the lower end of the cylinder C the die Q R is attached-the outer portion R by means of iianches and screws or bolts, and the inner portion or cone by the bolt or screw and nut t' of the head P, which is permanently attached to the cross-rod or bar e. Opposite te the post C We attach to thc cylinder C an arm or pendanQS', aud equidistant between the two, on one side, a similar one, S, to which are attached guide-grooves, or they are cut into them as shown, and also into a head attached to the post C.. Into these grooves are fitted guide-.heads U, so as to play up and down. To these guide-heads are attached guides or arms V, fitted to the groove s of the disk T, which'they support. On the under side of the arms V a double-acting cam, z', is placed, (tig. 12,) so as to approach nearly to the disk and to L the shortest incline a spring, y', is fastened, the point of which approaches so near the disk that in operation it will catch the heel t of the knives. The disk or cutting-wheel T is made of iron or other suitable material, and is about twofeet in diameter.. 'Its periphery isy provided with a square-shouldered groove, which is about.onc inch in width and'depth, in which the guide-arms V slide. On the under side, opposite to eachother, are placed brackets vg, which support the knives or cutters L. The knives or cutters h are about nine inches in length, and cut with either edge. At the outer end a heel or projection, t, is turned upwards, by means of which, with the cams t', the cutters are forced in, and also withdrawn. As the three supports of the disk are not placed so as to be equidistant from each other, we attach side-supports r(iigs. 4 and 10) to thearms V, which are fitted to the groove on the side opposite to the pendant S, and attach an arm or handle, u,i(g. 10,) to the disk, by which it is turned on the guide-arms V and side-rods r. Directly and centrally beneath the die we place standard l, `which passes through a cross-bar, Y, down into a har,- Z, near' the base A. This standard is provided with a turn-table or head, k, upon which the board X rests. This standard supports the pipe as it is being formed by means of a system of weights attached by the cords n. to the bar Z, which bar is tted into and slides in grooves made for its reception in the posts B. These posts are made hollow, and the interior is provided with steps or ledges z, sothat weights will rest at dierent points in the post. The lower weights are made slightly-wedging, or are chamfered-so as not to catch upon the ledges for the upper ones, and `they are strung upon a single cord, which is fastened to the lower one p. Two weights for cach post will be found sufficient, and, as the weights descend7 each one will bc left upon its own ledge, while the rope or cord will continue to pass through them until the last one reaches the bottom or the cord is taut. The upper ones o are made hollow,so thattheir weight can be increased or diminished as occasion may require, by filling or vtaking out sand, lead, or other detached substances. As the pipe increases in length it will increase in weight; so, as the standard Z descends with the bar Z, the detached weights will be taken up on the cord n, and the'supporting weights increased. The particular adjustment of the weights to the siz'e and consequent weight of the pipe will be made by the loose orv detached weight or substances in weight o. A carriage or endless carrier, D,is so vplaced below the board X, that when the pipe is Acut audits whole weight falls upon the board X, it will descend and rest upon such carrier; the foot is then applied to the treadle m, which. causes the standard to descend still further, and withdraws the turn-table 7c from the board, when it is removed with the section of pipe and another put in its place, when the foot is removed, and it is carried up to its place to receive another section of pipe.l The same weight is used to balance the disk and control it, as it is much heavier than the weight W, and is connected with the guide U of the post C by the eordf. The weights o are so adjusted and located that Lheweight of the pipe does not cause the lower weights to reach them until the section is ready to be cut, and as the weight then raises them, the disk is relieved from the weight ot' o, and will commence descending with the same motion as f the pipe or bar Z; and as soon as the entire `weight of the cut section comes'upon the boardX, it drops to the carriage or carrier, whilevtheI pins w prevent the disk from passing belowthe pendantsff; and when thc bar Z, with the standard i', a'scends, the `disk will also ascendv to its original position, In operation, the moistcned clay is placed in the hopper at D, when it is tempered and carried forward by 'the horizontal beater into the vertical one, which revolves in an opposite direction, so as to counteract, as much y as possible, the rotary motion of the pipe as it passes through the die. The rotary motion is also considerably checked by placing the lower internal line ot the cylinder B below the lowestflanges of the vertical beater. The rotary motion of the perfectly-formed pipe is therefore slight. The pipe, it will be evident, is forced through the die continuously. Different-sized pipes are made in the same machine by changing the die Q R. As thc pipe is forced through the die, it descends and strikes the board X,-,which at its highest point is only supported by the light weights p p. As the board descends, the weights p come in contact with other weights resting upon ledges similar to these shown, and so descends until the weights in their ascent reach weight o. The'dstancc the pipe has now descended being the length of the section, the disk will commence descending with the same motion, when'the section must be cut, which is done by taking hold of handle u and rotating the disk half-way Q, around, or accordingto the number ot' cutters. When the movement ot' the disk is commenced, the heel t of the y; 'cutters will come in contact with'the cams or` inclines st', which will force them forward through the pipe. When Vthe disk is rotated half around, the section will be cut, and the heels t of the cutters will come in contact with ,t the springs;l attached to the shorter side of the cam or incline, and the cutters will be withdrawn at the same instant that-the cutting is completed, and leftl in position by a slight reverse motion. The section of pipe -is carried from the machine on the carrier D with the board X as soon as released from the head lc, and; when 4 carried from the machine, is taken from the carrier by a pair of tongs, shownvat tig. 9, which is provided with i feet g, fitting the boards X, and carried any desired distance. A large number of the boards X will he found desirable. It is necessary to make clay pipe ot" large diameter vertically, to prevent its collapsing, also to support it so that it will neither stretch.n0r bilge, and to sc construct the support that it will partake of the rotary -motion of the'pipe, which, to a greater or less degrce, is unavoidable, (and, -to a degree suicient to polish the 1 pipe, desirably,) when made continuous by screw-beaters. The boards X revolve freely upon the mandrcls K of the standard, so that all of these conditions are fully met in our improved machinery, by which clay pipes of a large diameter can be accurately and rapidly made. We do not claim the cylinders and beaters broadly, as, taken separately, both have been before known and used; nor do we cla-im broadly the useor employment of weights coming into play at several stages in the descent of a receiving-platform for the pipe, as the;l have been heretofore known and used in a cumbersome form, each weight having a. separate part or support and a separate cord; but whatwe claim as new, and as our invention, and desire to secure by Letters IPatent, is a 1. The grooved disk T, when applied to a clay-pipe machine, and arranged to descend while cutting the pipe,.w.ith the same motion asthe pipe. 2. The combination of a suspended rotating disk or wheel, T, with one or more cutters i. 3. The weighted guide-heads U, when provided with ai'ms V,'substantially as and for the purposes specified. 4. The two-edged knives or cutters'h, provided with the heel or projection t. 5. The cams z', provided, with the spring j, substantially as and for the purposes specified. 6. The combination and ,arrangement of the cams z' and springs j with the cutters h, heel t, and rotating disk T. i l 7. The combination and arrangement of the guide-heads U with the weights o and W, substantially as specified. i 8. The arrangement of the Weights op upon a single cord, so as to increase the weights as they ascend, substantially as specied. 9. The rests or ledges z, in combination with a series orA weights increasing in lateral dimensions, operated by a single cord, substantially as specified. i V ` 10. The arrangement and combination of thecross-bars Y Z, standard Z,- and mandrel k, with the cords n, weights op, and ledges z, substantially as and for the purposes specified. l 11. Tile combination and arrangement of a descending platform for receiving vertical pipe, constructed and arranged substantially as specified, with a rotating disk provided with cutters, and descending-with the same motion as the platform while cutting, substantially as specified. - GEORGE D.
