T0 00% whom, it may concern.-
Be it known that I, AUGUST FARRENSTEINER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Shaping and Cutting Machines, of which the followingis a specification.
My invention relates to that class of machines which are provided with a number of operating-tools revolving in circular paths about the article being operated on.
The principal objects of my invention are to produce a simple and efficient machine of this kind, to adapt the same particularly for use in shaping the external surfaces of tubular and cylindrical articles, such as metal pipes, as by smoothing or forming in them annular depressions, and to provide in connection with such arrangement a convenient and accessible cutting device.
To this end my invention contemplates providing a rotary carrier for the tools and arranging the latter upon the carrier, so that they may be moved toward or away from the article in question when the carrier is in motion or at rest, and providing, further, a central holder adapted to receive said article and maintain the same in a stationary position while being operated on by the revolving tools.
As a preferred arrangement the operatingtools are supported at the ends of a number of levers, which are arranged upon the carrier parallel, or substantially parallel, to its axis of rotation and which vibrate in radial planes to reciprocate the tools into and out of operative position.
In case the article in question is tubular the central holder consists of a mandrel upon which the article may be slipped and held during the operation.
The cutting device is arranged conveniently near the rotary tool-carrier.
In the accompanying drawings, Figure 1 is a side elevation of a machine embodying my invention. Fig. 2 is a top plan View. Fig. 3 is an end elevation, and Fig. 4 is a central and vertical longitudinal section of the same. Fig. 5 is an end elevation of the rotary toolcarrier. Fig. 6 is a central longitudinal section of the same, showing a. section of pipe undergoing operation. Fig. 7 is an end elevation of the cutting device and a pipe-section in position to be cut thereby. Fig. 8 is a side elevation of the same.
The machine I have shown is arranged for operation at both ends and is particularly adapted for service in connection with metal pipes and analogous'tubular articles. One end is equipped with mechanism by which the pipe may be externally smoothed and the other with mechanism for forming a peripheral groove or indentation in the same. The machine therefore is provided with the frame or bed A, which is mounted 011 suitable legs a and which supports the central standard B. To the sides of this standard 13 are bolted a couple of cylindrical-shaped castings O, which are arranged to lie horizontally over the bed A in the direction of its length and which form the supports or bearings for the rotary tool-carriers D. These tool-carriers D are also desirably cylindrical in' form and are internally bored to fit over the supports or bearings C.
In order to avoid objectionably great contacting surfaces between the internal supports or bearings C and the rotary tool-carriers D, one or both of the opposing surfaces on the same are reduced for a portion of their length, forming a recess 0, Fig. 4, between the two.
As a means for preventing longitudinal movement on the part of the tool-carriers the supports 0 are provided with the annular flanges 0, against which the inner ends of the carriers D are set, and the rings or collars E, having annular recesses corresponding to the flanges c, are bolted against the ends of the carriers, thereby embracing said flanges. This arrangement also allows the gear-wheels F to be secured to the tool-carriers for communicating a rotary motion thereto, said Wheels being fitted over the ends of the carriers and bolted between the rings E and the lugs G on the carriers.
The rings or collars E are desirably constructed in two sections and secured together by the bolts e. (Shown in Figs. 1 and 2.)
The operating-tools are carried by a number of levers H, which are shown pivoted at points 72 at the outer ends of the tool-carriers C, so that the vibratory movement of the levers will swing the tools in radial planes. As a means of swinging these levers the collars J are mounted upon the carriers, so that they rotate with the latter, but are capable of independent longitudinal motion as well. The inner ends of the levers II are connected to the collars by the links K, the arrangement being such that a movement of either collar toward the end of the machine to which it is nearest will result in operating the levers attached to it to move the tools radially inward. The springs L tend to hold the collars J normally away from the outer ends of the carriers.
As a means for causing the longitudinal movement of the collars J, I have provided the levers M, which are operated by the treadles N. The latter are pivoted at n to the bed of the machine A and provided with the angular extensions N, having at their lower extremities the bolts n, which slide in the slots min the levers. These levers M are pivotally connected to the bed of the machine at m and are arranged to swing in planes parallel to the longitudinal axes of the toolcarriers. Eachlever Mis branched or forked above its point of pivotal support m, as best shown in Fig. 3. These forked portions are arranged to lie on either side of the collar J and are provided at their upper ends with pins M, which engage the groove j in said collar for longitudinal movement independent of its rotary motion.
I have shown at the right end of the machine, Figs. 1, 3, and 4, tools for smoothing the external surface of a metal pipe, as, for instance, a welded joint between two pipe-sections. (See Fig. 4:.) These tools consist of a number of rollers or smoothing-wheels P, in this case three, which are carried by the slides P, which latter are adjustably held in the slideways Q, secured to or forming a part of the levers H. A downward pressure on the right treadle N will move the collar J outward, thereby swinging the levers II and forcing the wheels P against the rough portion of the pipe. The rotation of the tool-carrier causes the revolution of the wheels P around the pipe, which is continued until the latter is properly smoothed. The pipe is preferably held during such operation upon the mandrel R,which is rigidly held by being fitted at the center of the support G. This mandrel B may be of a diameter to accommodate the smallest size of pipe to be treated and is desirably constructed with a detachable end section B, which may be replaced by similar sections of greater diameter for pipes of larger size, it being evident that the pipe need fit the mandrel closely only at such points as are subject to the action of the rollers P.
At the left end of the machine I have shown, Figs. 4, 5, and 6, mechanism for forming a peripheral groove in a pipe. Such mechanism consists of wheels or rollers S, carried by the slides S,which are adjustable in the slideways S, Fig. 2, the latter being secured to or forming part of the levers 1-1. These levers H are connected and operated as are those at the other end of the machine. The revolution of these wheels or rollers S, while pressed against the pipe X, will form in the latter an annular groove, as shown in Fig. (3. In order to limit the depth of the groove, I have provided the stops T, which extend radially inward from the extensions H of the levers H. The inner ends of these stops are recessed at T, the curvature corresponding to the convexity of the pi pe-section X and their sides are beveled, as at T, the result being that when the levers H are swung sufficiently to cause the stops T to come into contact with the pipe X the concave surfaces T on the stops completely embrace the pipe and their beveled edges T meet, thereby preventing any further inward movement of the rollers S and limiting the depth of the gooove in the pipe.
The stops T are desirably made adjustable, and to this end I have shown them connected to the lever extension 11 by the bolts t,by turning which grooves of greater or less depth may be formed.
The pipe may be held in various ways, but, as a matter of further improvement, the mandrel R is extended, so as to be available at this end of the machine also, and the pipe is slipped thereupon, as shown in Fig. 4. It will be observed that in order to permit easy access to the mandrel and the ready manipulation of the pipe upon the same the supporting-heads O are bored for a portion of their length, as shown in Fig. 4.
At the outer ends of the tool-carriers D, I have shown the flanges d, which serve to protect the tools from external interference and also to prevent them from flying outward in case they should become loosened.
In Figs. 2, 3, 7, and S is shown the cutting device, which comprises the rotary cutter a, which may be a suitable tempered metal disk mounted on the shaft to, and the reciprocating rod V, carrying the wheels V at its upper extremity. The rod V is subject to the spring \V, tending to force it away from the cutter u, and is operated by means of the foot-lever Y and may be, if desired, inclosed in a casing, as Z, Fig. 3. In practice the pipe is placed upon the wheels V and the lever Y depresed, thereby forcing the pipe against the cutter a. The pipe may then be turned to permit the action of the cutter around its entire circumference.
A convenient arrangement is to provide a cutting apparatus at each end of the machine whereby a length of pipe may be operated on by either set of revolving tools and then cut at that end of the machine, or vice versa. WVith this in view I have mounted a cutter at each end of the shaft u, and provided cooperating mechanisms for each cutter, and have supported said shaft at one side of the rotary tool-carriers by means of the standards A, whereby a cutting apparatus may be reached bya side movement from either tool-carrier.
IIC
The standards A also support the rotary driving-shaft A which is situated between the shaft to and the tool-carriers and transmits power to both the intervening gearwheels. A couple of belt-pulleys A are provided for said shaft, and a fly-wheel A may be added, if desired.
What I claim is- 1. In a machine of the class specified, the combination of the rotary tool-carrier having a hollow longitudinally-extending cylindric portion; the cylindric support adapted to fit within the bore of the cylindric extension of said carrier; a number of levers arranged longitudinally of the tool-carrier, and pivotally connected therewith so as to swing in planes which are substantially radial to the axis of rotation; a collar surrounding said carrier and arranged for sliding movement longitudinally of the same; links connecting said levers with said collar; a pivotally-supported lever having forked portions which are arranged on either side of the said collar, and are provided at their ends with means for engaging said collar for sliding movement; and spring means tending to retain the collar in the position in which the levers lie as nearly parallel as possible to the axis of rotation of the carrier, as set forth.
2. In a machine of the class specified, the combination with a rotary support for the grooving-Wheels S, of adjustable stops attached to said support and arranged to meet the article being grooved when the groove is sufficiently deep, as set forth.
3. In a machine of the class specified, the levers H provided with the adjustable grooving-wheels S, and with adjustable stops T having recessed ends T and beveled sides T, substantially as, and for the purpose set forth.
4. The combination, with the rotary cutter, of the reciprocating rod V, provided with the wheels V; the spring W to which the rod is subject; and the operating-lever Y, substantially as described.
