MACHINE FOR CUTTING AND CRIMPING PIPES.

To all whom it may concern:

Be it known that we, THEODORE A. JANs- SEN and HARRY W. MoA'rs, citizens of the United States, residing at Sterling, in the county of Whiteside and State of Illinois, have invented certain new and useful Improvements in Machines for Cutting and Crimping Pipe and we do declare the follow ing to a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use 'the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

Our invention has reference to machines for cutting and crimping pipe, and is specially designed to be used in operating upon pipes formed of light material, such as stovep I3y the use of the device it is possible to cut the pipe at a pre-determined point and crimp the opposite end thereof in thesame operation, the pipe being held and fed in the machine so as to insure a perfectly true cut, at right angles to the line of the machine. It is also possible, by a slight adjustment to cause the pipe to be out only, the crimping mechanism being rendered inoperative.

In the drawings: Figure 1 is a side elevation of our invention. Fig. 2 is an enlarged detail, with the plate 53 in position. Fig. 3 is a detail, showing the collars 36 and 37 in side view. Fig. 4 is a rear view of the plate 43 and appurtenant parts, with some of-the parts in cross-section. Fig. 5 shows one of the blocks 54, in detail. Fig. 6 is a vertical cross-section, in the line w0c of Fig. 1.

Similar numbers refer to corresponding parts throughout the several figures.

1 represents a support, adapted to be fastened to a bench or other suitable place, by means of a clamp-foot 2 and bolt 3 therein. A standard 4 is revolubly mounted in the support 1 by means of a cylindrical shaped shank 5 on the lower end of such standard, engaging a similar recess 6 in the support. Such standard may be held from rotation by means of a set-screw 7 held in the wall of the support 1 and impinging the shank 5 with its inner end. Greater stability of the part 4 upon the support 1, and greater ease of operation thereof, is secured by means of a circular plate or collar 8 on the lower end of the Specification of Letters Patent.

standard 4, and a similar plate 9 on the upper end of the support upon which said firstnamed plate rests.

Integral with the standard 4 is an arm 10, provided on its outer end with a bearing 11, the standard 4 being also projected upwardly into a plate 12, integral with the upper part of which is an arm 13, parallel with the arm 10, and in vertical alinement therewith. On its outer end the arm 13 is provided with a head 14.

A rotary shaft 15 is journaled near its outer end in the bearing 11, and near its inner end in the plate 12, the inner end thereof being provided with a crank 16. A similar shaft 17, parallel with the shaft 15, is supported near its outer end in the head 14, and at its inner end in the plate 12, rotation being imparted to the shaft 17 from the shaft 15 by means of a gear wheel 18 fixed on the latter shaft and meshing with a similar wheel 19 on the shaft 17.

The outer end of the shaft 17 is capable of vertical movement by being supported in a block 20 having vertical play in a recess 21 in the head 14. The block 20 can be raised or lowered by means of a screw 22 working in a threaded perforation 23 in the head 14, the lower end of the screw 22 being provided with a circular plate 24 held in a recess 25 in the upper face of the block 20 by means of a plate 26, secured to the face of the block, and through which the lower end of the screw passes. The upper end of the screw 22 is provided with a crank 27 by means of which it is operated.

The inner end of the shaft 17 is permitted a limited amount of vertical flexibility by means of a recess 28 in the upper part of the plate 12, in the lower end of which recess is a journal-block 29 bearing upon the upper face of the shaft. In the upper end of the recess is a bolt 30, between which and the block 29 is an eXtensile coiled spring 31.

On the outer end of the shaft 15 is a feedroll 32, integral with which is a rotary cutter 33, and on the outer end of the shaft 17 is a similar feed-roll 34, enga ing the feed-roll 32. Integral with the feed-roll 34 is a rotary cutter 35, adapted to work with the cutter 33 in cutting the pipe.

A pair of collars 36 and 37 are slidably mounted on the shafts 17 and 15, respectively, by means of ribs or feathers 38 on the inner faces of the collars, engaged by longi tudinal channels 39 in the shafts. The collars are held in vertical alinement by means of annular grooves 40 therein, engaged by a pair of plates 41 secured to a plate 42. The plate 42 is permitted vertical movement independently of the shaft 15 by means of a recess 43 in the lower end of such plate, and by means of an opening 44 in the upper part of the plate 42 the shaft 17 is permitted a limited amount of vertical play independently of such plate.

At one side the plate 42 is provided with a perforated ear 45, in which is held a set-bolt 46, and at the opposite side said plate is pro- Vided with a perforated ear 47 in which is held a thumb-screw 48. The bolt 46 and screw 48 are adapted to impinge the sides of the arm 10 with their inner ends, and hold the plate 42 rigidly attached thereto. Fixed to the collar 36 is a crimping-roll 49, and a corresponding crimping-roll 50 is secured to the collar 37. Integral with the rolls 49 and 50 are feed rolls 51 and 52, similar to the feed- rolls 32 and 34. A plate 53 can be attached to the outer face of the plate 42 by means of a thumb-screw 54 held in perforations in such plates. The plate 53 is held from movement upon the screw 54 as a pivotal point by means of arms 55 bearing upon the edge of the plate 42. The plate 53 is of the same thickness as the crimping rolls, and when in position prevents the'insertion of the end of the pipe beyond the inner edge of the feed- rolls 51 and 52, and prevents the crimping of the end of the pipe. The plate 42 may be provided with a similar plate 53 on the opposite side of the machine, if desired. On one of the faces of the arm 13 is a gage 56, indicating in feet and fractions of a foot the distance from the cutting point of the wheels 33 and 35.

- To operate the machine the thumb-screw 48 is loosened, permitting the plate 42 to be moved longitudinally of the shafts 15 and 17, such plate carrying with. it the collars 36 and 37 and crimping and feed rolls attached thereto, The plate 42 is again secured in place at the point which will give the desired length to the pi e to be severed, by re-setting the screw 48. f it is intended to crimp the end of the pipe the plate 42 is set so that the outer face thereof is on a line with the mark on the gage 56 which indicates the desired length of out. If it is intended to cut the pipe, without crimping the end thereof, the plate 42 is set so that the line between the crimping wheel 49 and feed-roll 51 is opposite the desired mark on the scale. It will be obvious that with the plate 53 attached to the plate 42 the inner end of the pipe will extend to the inner edge of the feed- rolls 51 and 52.

With the plate 42 located in the proper position, the crank 27 is operated to raise the shaft 17, separating the feed- rolls 32 and 34, and also the cutters 33 and 35, sufficiently to permit the insertion of the pipe. The same operation opens the feed- rolls 51 and 52 and crimping wheels sufficiently to permit the engagement of the end of the pipe thereby. The pipe is then inserted, and the crank 27 operated to lower the shaft 17, causing the pipe to be engaged by both pair of feed rolls, by the cutter-wheels, and by the crimping wheels, if such wheelsare being used. By the operation of the crank'16 the shafts 15 and 17 are then rotated toward each other, resulting in the cutting of the pipe.

As the feed- rolls 51 and 52 are similar to the rolls 32 and 34, and rotate coincidently therewith, the pipe which is being cut is rotated with the same degree of speed at the inner end thereof, as at the point where the cutting is performed, resulting in an even circular cut, at right angles to the line of the p1 e.

.lt is necessary to have the arms 10 and 13 of sufficient weight and strength to prevent the cutter-wheels from springing apart during the cutting operation.

The amount of flexibility of the shaft 17 at its inner end may be varied by raising or lowering the bolt 30, whereby the tension of the spring 31 is correspondingly diminished or increased.

What we claim as our invention, and desire to secure by Letters Patent of the United States, is:
