IMPROVEMENT IN CLAY-PIPE MACHINES.

TO ALL WHOM IT MAY CONOERN:

Be it known that I, GEORGE D. GOODRICH, 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 I do hereby declare that the following is a full, clear, and exact .description thereof, reference being had to the accompanying drawings of two sheets, forming a part of thisspecitication, in which- Figure 1 is a side view with a portion of one of the posts removed.

The nature and object of my invention consist in constructing u series of machinery to be used in ther manufacture of clay pipes for drain tile, sewer pipes, Src., so that the operation will -be continuous from the time the clay is forced through the mould until the same trough is returned to receive a section of pipe, and the pipe cut into properlengths or sections from a mould 'through which the pipe is passed-continuously; in providing such machinery with an improved platform for receiving-the pipe from the mould into the receiving trough; in providing a wheel to operate the sliding-shaft and'cutter; in providinga sliding-bar below such platform with stops to regulate and adjust the lengths of the section of pipe; in providing such wheel and sliding-bar with cams and spring; in providing the wheel with arms extending beyond and the entire length of the receiving platform to which the cutting wiresare attached; in constructing and providing an elevator i at the side of the receiving platform, and operating at the side of asingle post or standard to receive and elevate the trough and pipe; in the peculiar arrangement and construction'of such elevator; in providing such postV or elevator with an automatic stop and rest; iu the peculiar construction of such rest; in providing the operating shaft with a cylinder operated by a lever-spring catch and conical or wedge-shaped retractor; in providing such machinery with a post orstanda-rd, having guides on the side to guide the dumping platform in providing dumping platforms, one of which will operate the other in the peculiar construction of such dumping platform in providing a. platform to receive the empty troughs from such dumping apparatus, and in the several combina- "tions hereinafter set forth and claimed as new.

To enable other skilled in the art to make and use my invention and my improved machinery, l will proceed to describe its construction and operation. Y Y

It is designed to use this machinery in a two-story building, in which event A1 will represent the first door, and Az the second, and the posts of the frameA will represent the walls or supports of the building. In a onestory building thc frame A will be made in any convenient manner. The mould is not represented, but the -pipe is discharged from the mould through the standard or post, B, on tothe sliding support, C, which will slide upon the arms j so as to occupy a portion of the space between the post- B and the trough O. I attach a post, H, to the floor, opposite the post 13, at a. suitable distance therefrom; and at a proper distance above the floor to give the arms of the cutter a free movement I insert a bar or shaft, J. 'llo this shaft I attach the wheel I and collar b, of the cutter and the lo'wer arms or timbers of the carrying device. These arms, L, areiprovided on each side with screws, a rt, upon which the cross-bars t and m rest, and by means ot' which the height of the frame is adjusted to adapt itto the size of the pipe passing into the trough O. To these cross-bars m and on I attach wheels or rollers, 'l, which'extend beyond the bar m, and arc provided with flanges at each end to keep the movable platform N', (more fully shown at tig. 13,) in position. Cross-timbers or bars, H', supporting the crosswheels or rollers. yu., are placed upon the bars m.. The rollers 11 are also provided with Hanges, and project slightly above the movable platform N'. Upon these c1ossrollei's the trough is placed, as shown. To the shaft attach a slidingfbar, K, at the upper side this shaft at the outer end it may he attached to C by z', or left, as .own; and naar this 'posses under the collar b of the cutter; at the other end the arms or stops dare attached. heee arms d project upwardssuiiciently to stop the friction of the pipe from carrying the trough O over-thi rame, und the shaft is secured in place by passing under the rim of the circular band, Z, of the wheel I, (figsv 1.5 and 17.) 'llo the sides, of this bar J l attach a spring, g, (tig. 17,) which is provided with a'hook, fz, whidh operates on a catch, 1.', which is attached to the sliding-bar K, and is unhooked by the camsfk of the plate l of the wheel l. To the wheel l are attached arms, c c, at Vopposite sides, which are extended far enough to allow the lient portion to pass entirely around the receiving frame or device, and are long enough to pass beyond said frame. To the bent'portion of these arms l attach small \vires,'ff, at their outer ends, and at vthe inner ends they are attached to the Wheel l and the collar in any-convenient manner. 'lhcse wires are placed so as to come very near the ends of the trough 0, and' by giving the wheel l a half revolution, cut the continuous pipe into proper lengths or sections, when it is ready to bc removed and elevated to the upper floor. For lthe purpose of elevating it I attach to the side ofthe standard or post D, which has a T-shapcd groove or guide, Z', 'which guides the head P of thc elevator. This. lread ('gs. 4, 5, and 6,) is made of suicient length to keep it steady and prevent bending on the guide, and on each side is a. projection, .which has'an upper and lower cam, o and n, .and to its front is attached a plate, m', which is provided' with arms, Il, that are carried outfand bent to receive the ends of the ytrough O. At the upper end of the head l? thercis an eye orloop attached, into which the cord, @,is fastened; a similar one is made at the lower end to attach a weight if necessary.' At a proper distance above the second door or top of the framabeut arms', W, (liga. l, 2and 3,) are hinged' to the sides of the pgst D, so as to stand over the bent` arms l Z. The ends 'of these arms are extended through the post D into the guide cavity Z, so as to he operated by the 'cams n and o at the sidesV of the elevator head l. They are also provided with springs, 2, to throw them under the trough O assoon as ithasbcen elevated to the required height. These springs, in the form of attachment shown, at their outer ends rest Vagainst pendent projections attached to the bent arms, but may be applied directly tothe back of the arms',or in any convenient manner, the design being to malte the arms work automatically, so that the attendant will not need to he alivays at this point. To complete the automatic Working I attach to a driving-shaft, Q, a small head, z, permanently, and .fi-cylinder, R, loosely. This cylinder is slid` upon the shaft by means of the lever w, and when brought against the, head :c it is held by friction or proper clutches, and secured hy the spring u, which is provided -With a stop, y, (figs. l and 4,) that rests against the upper end of the lever w. A cord, q, is attached to this'cylinder and passes up over a sleeve or pulley on the top of the post S, and over to a similar one at the top of the post D, and down to the head P of the elevator. '.loA this oord attach a conical block, t, which is attached to the cord at such a distance from the springV u as that when the elevator passes the bent arms w, this block will press the spring and release it from the lever w, so that the cylinder R will cease revolving with the shaft, and'the elevator commence descending. The upper end of the lever w is made wide enough for the stop y of the spring u to rest 'against it in, order to prevent the conical block from catching in its ascent. The empty troughs are lowered by means of the apparatus attached to the shaft E, shown at figs. 1, '.7, 8, 9, and 10. This standard or post is provided on bpposite sides with T-shaped grooves or guides, Z, similar to that in post l). The top of this post is provided with cross-bars, t" i', which support the frictionuollers g g', over which passes the cord a', which supports at each dnd a dumping frame, only one of whichfis shown, but both are made alike, and a description ofcne will apply tofbrth. The head h is fitted to the interior of the guide groove Z, andhas a projection at its front to which the upper end of the arm Y is hinged. .This arm is also bent, and is of suflicient length to pass over and to the bottom of aftrough, where its lower end is hinged to a projection, e', of the bottom X.' The bottom X has eyes or loops at each end, and lateral projectionspm, at the inside, which are fitted to the sides of the post E. bail, b', bent in the form shown in figs. l and 9, is attached at the eyes e to the bottom, and at .the upper end to the cord a. This cord a passes over and around the rollers or pulley g and under. the friction clutch c, (iig. 8,),and is provided with a swelled or double conical block,'f, which operates the friction clutch d', which is also double acting. Thel object of this is to check the motion of the dumping frame in its descent, so that the empty troughslwill not be precipitated upon the platform F withtoo much force and injure the troughs. When the bottom X passes .below the end of the post E, it swings under the end of said post, when it will turn upon the bail la and dump the trough; the block f should therefore be so located that it will strike the friction clutch just before the bottom X passes below the end of the post, and being double acting only one will be required forbcth frames, but if desired it can be duplicated and pla-ced on both sides. A. dumping platform F, provided with rollers v, is placed below the end of the standard or post E, te receive the empty troughs as they l escend. The rollers v are placed on the same plane as the `upper rollers u of the receiving frame. This platform is'supported in position by any convenient method. The sizes of' the several posts of my machinery will be governed by the length of the sections of clay pipe to be made, and by the material used in its construction, as it can nearly all be made of wood, or may be economically made principally of iron. Ordinary sections of pipe weigh from forty to about one hundred and twenty pounds in the trough, so that a strength of parts which will sustain a Weight of two hundred pounds iivill be sullicient.

The `operation is as follows: The ground or prepared clay is forced at 1 Ifrom the mould through the post` B into the sliding rest c which slideson its arms j', about half-way from the .post to the trough, and should be located about one-eighth of one inch higher than the trough O it then passes into and through the trough, which4 is prevented from sliding or rolling back bythe stops a, which are held and locked by the springs g. When the pipe has passed'through the trough the attendant then takes hold of the arm e and gives the Wheel I a half revolution, which fmotioucauses the wiresfto pass through the pipe and cut it at both ends, and also releases the spring catch g k by means of the cams k and the stops d, when the trough is rolled back till the Acircular cavities nf' are directly over the rollers u, which lets the trough down on to the platform'li which rests upon the rollers T, when it'is pushed with N down to the post D, 'which brings the trough over the arms Z. The cylinder R is then thrown into gear and it is taken up on the-elevator; platformN is immediately returned to its position,`

another trough taken from, platform F and rolled to the same place which the other occupied. When the head? of the elevator reaches the points 7: of the arms w, the cams o, pressing against the back of the points fc', open the arms'and allow the 4trough to pass through, and the springs z will return them as soon as the trough passes them, or the points r pass the lower end of P g and to ensure their perfect Working, the cams n atthe lower end of the head block Pstrike against'the front of the points 7c and force them under suiliciently by its weight in descending., A'ssoon as the head block is'pa'st the points la', theblock t on the cord strikes the spring u and releases the cylinder R, when the' elevator will descend, leaving the trough on the spring arms zu this is necessary, as it would require an additional attendant if this part did not work automatically. The trough is then taken and emptied, when it is thrown on to the platform X, where its Weight causes it to-descend. The

peculiar construction and method of hanging this platform causes it to vkeep nearly horizontal until it `passes the bottom ofthe post, when it will cant and slide the trough ol into platform F, when it is ready to be used again, and the friction clutch d with the conical block j will break the'force of the descent so that it will be landed without injury. I use five of the troughs O in, operating the machinery, and when complete .will be found-very useful in the manufacture of clay pipes, where the pipe is made continuous and in ahorizcntal position.
