CRlMPlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 349,355, dated September 21, 1886.

Application filed May T, 1886. Serial No. 201,495. (No model.)

To all whom it may concern.-

Be it known that I, FRANK It. PAOKHAM, a citizen of the United States, residing at Mechanicsburg, in the county of Oliampaign and State of Ohio, have invented certain new and useful Improvements in Crimping-Machines, of which the following is a specification.

This invention relates to that class of crimp ing-machines in which two crimping-rolls mounted on separate bearings are adapted to intermesh and be revolved to crimp the ends of pipe or other similar articles, to produce a taper thereon.

The obj ects of the invention are, first, to provide a crimping-machine for crimping pipe or other articles, and adapted to form an ogee groove or head at the same operation which produces the crimping, the machine being capable of an adjustment whereby the ogee or heading rolls may be dispensed with without the necessity of supplying blanks to fill the spaces previously occupied thereby; second, to provide for crimping short flanges or projectionssuch as bucket-lids, &c.whereby the projecting flanges or rims thereof may be formed 011 a taper when made from a straight piece of metal; third, to provide a novel arrangement for adjusting the angle of the rolls, to produce a greater or less taper and vary the depth of the crimps; fourth, to provide for varying the depth of the beading with reference to the crimping, whereby light or heavy bead-' ing may be produced with any desired length or depth of crimps, fifth, to improve the general construction of machines of this class, cheapenin g their construction, and at the same time adding to the efficiency of their work. To this end my invention consists in the various constructions and combinations of parts hereinafter described, and pointed out in the claims.

I11 the accompanying drawings, Figure 1 is a side elevation view of a machine embodying my invention. Fig. 2.is a plan view of the swinging arm for supporting the upper roll, the ogee-roll being shown thereon in dotted lines. Fig. 3 is a sectional elevation View of the frame, the upper supportingarm being removed. Figs. 4 to 8, inclusive, are detailed views of some of the various'parts. Fig. 9 is a front elevation view showing the supplemental Shaft in the upper supporting-arm.

Fig. 10 is a side elevation view showing the machine adapted for crimping short projections or flanges. Fig. 11 is a transverse sectional elevation view on line X X in Fig. 10. Fig. 12 is a detailed view of the supplemental shaft with the roll shown in section thereon. Fig. 13 is a detailed view of the auxiliary roll.

Like parts are indicated by similar letters of reference throughout the several views.

The main frame A consists, essentially, of the bearing B, at the bottom of which is aprojection, B, to fit the usual supporting-standard, and a single upwardly-projecting side or wing, A. To the rear end of the wing or side A is pivoted .a supporting-arm, O, which is providedat the front end with a sleeve or socket, 0, adapted to receive the shaft or hearing which supports the upper roll, D. The lower roll, D is supported on a shaft, D which extends through the bearing B of the main frame. The rolls D D are provided in the usual manner with a series of serrations or flutes to produce the crimps, and are preferably made of the same diameter throughout. In order that the crimps may be produced of a varying depth, and thus form the crimped end of the pipe on a taper, the upper shaft or bearing is supported at an angle to the lower shaft, D.

It is sometimes desirable that the angle at which the rolls stand in relation to each other he changed, so that the taper may be formed for a greater or less distance on the end of the pipe and a variation secured in the depth of the crimps. Itis desirable, however, that the rear ends of the rolls remain flush with each other. In order to provide for this adjustment, I support the pivot a, on which the swinging arm 0 is journaled, in a slotted open- 0 ing, a, formed inthe wing A on the arc of a circle struck from the intersection of the crimping-rolls at their rear ends.

The pivot a. is preferably made in the form of a bolt, which passes through the slotted 5 opening a, and is provided at the outer end with a nut adapted to screw thereon, a shoulder being preferably formed, so that the bolt may be tightened in the side wing of the frame without binding the supporting-arm thereon.

The socket or sleeve 0, in which the upper shaft, D is supported, is of the same diameter throughout, and is provided on one side with a set-screw, b, by means of which the shaft "f in the shaft D.

D" will be held in any desired position in said sleeve. On the upper part of the wing A is a projectinglug, 0, through which projects the end of the usual hand-screw, c, the end of which is adapted to bear against arm 0 to adjust the position of the upper roll, a coilspring, a, supported on the frame A, being adapted to support the weight of the upper roll and the swinging arm 0 and press said arm against the adj Listing-screw c.

The upper shaft, D, is preferably passed through an arm, (I, provided at the rear with a small projection, (7, adapted to engage in an opening, d in the frame A. This lever d is provided with a hook, to which may be attached a chain or suitable connection leading to a foot-treadle, by which the position of the upper roll may be changed, thus dispensing with the use of the hand-screw c.

E E are the ogee or beading rolls, which are usually employed in connection with the crimping-rolls to produce a groove or head in the pipe being crimped. In order that these rolls may be dispensed with, when desired, without the necessity of supplying their place with blanks, as heretofore, i so construct and arrange the shaft D that it may be readily moved longitudinally to take up the slack or space left at the end thereof when the beading-roll is removed. To do this I construct the shaft of the same diameter throughout, and provide means for securing the shaft against longitudi nal motion in the different positions of adjustment, which means permit the shaft to be revolved in either position of adj ustment. The shaft is also provided at the forward end with suitable means for connecting the rolls thereto, so that said rolls will revolve therewith, but in such a manner that the shaftmay be moved longitudinally in relation thereto. This I preferably accomplish by providing in the forward end of the shaft 1) a keyway, c, with which a suitable spline or projection, e c'-', on the rcspective rolls is adapted to engage.

At the rear end of the frame A is provided a hinged latch, f, adapted to engage in grooves The rolls are held 011 the end of their respective shafts by means of nuts F F. These nuts are preferably screwed into the end of the shaft and are provided in the center with a suitable opening, {1, adapted to receive the end of a square key or wrench, by which they may be screwed into or out of their respective shafts.

\Vhen it is desired to use the machine without the ogec or head rolls, the nuts F F are withdrawn and the ogee-rolls removed. The latch f is raised from the groove 1'' and the shaft I) slipped back until in the position shown in Fig. 3 the latch f is dropped into groove f, The set-screw b in the upper supportingarm, 0, is loosened and the shaft (1 is slipped back through the sleeve 0 until the space oeoupied by the roll E is taken up. The nuts F F are then replaced and the machine is ready for operation without the ogee-rolls.

The nuts F F, I preferably make with a very thin head, which, if desired, may be countersunk in the end of the roll. in this way when the ogeerolls are removed the ends of the crimping-rolls are left unineumbercd, so that they may be employed for crimping short projections or fiangcssuch as the projections of bucket-lids, 850.

It is sometimes desirable, especially when crimping stove-pipe of poor quality, thata variation be effected in the beading formed therein without varying the crimps or taper of the end of the pipe. For this purpose I provide a supplemental shaft, D", adapted. to fit into the sleeve 0 of the supporting-arm C. This shaft D is provided at the forward end with a cam, D on which the ogce-roll is journaled, the crimping-roll beingjournaled on the main part of the shaft in the usual manner.

The end of the shaft 1) is provided with a socket, adapted to receive the end of a suitable key or wrench, by means of which the shaft may be turned to any desired position.

XV hen it is desired to effect a variation in the groove or bead without changing the crimp produced in the pipe, the shaft D is removed from the sleeve and the shaft 1) substituted therefor.

It will be seen that by turning the shaft D in the hearing or sleeve 0 the ogee-roll may be broughtinto any desired position with relation to the lower roll. The crimping-roll being journaled on the main portion of the shaft, whose centeris on a line with the center ofthc sleeve C, no variation is produced therein by the revolution of theshaft l). The ogee-roll, however, being journaled on the cocentric portion D of the shaft, maybe placed in any desired position with reference to the lower roll by simply turningthe said shaft in its bearings. The eccentric is preferably formed so that, if desired, the ogee-roll may be raised sufficiently so that it will be entirely withheld from contact with the work.

In order that the swinging arm 0 may beheld firmly against lateral motion, and at the same time be permitted to rise or fall in :uljustment of the ei-impingrolls, 1 provide on the side thereof a projection, ll, near the front end, adapted to pass through a slotted opening, h, in the side or wing of the frame A, a washer, h", being provided thereon on the outside of the said wing, as shown in Fig. 11.

The side of the arm 0 next to the wing A. is faced off to form abearing against the said wing. By this construct-ion thearm isadapted to move freely up and down upon its pivotal bearing a, but is held against lateral motion thereon.

In Figs. 10 and 13 I have shown crimpingrolls adapted expressly for crimping short projections or flanges, such as the projections or rims of bucket-lids or similar constriurtions. These rolls 1) D are each provided with an extended sleeve or collar adapted to take up the space on the respective shafts D and D occupied by the cri mping-rolls and ogee-rolls. The lower roll is provided with a suitable projection adapted to engage in the keyway in shaft D, the said rolls being of sufficient length to stand flush with their respective shafts on the said journals.

When it is desired to crimp a projection close up to a shoulder or corner, the nuts F F may be dispensed with, the pressure of the work against the rolls being sufficient to hold them in place.

It will. be seen that by the construction above described I provide a machine capable of ready adjustment for any kind of work. The frame, being formed with a single wing or side projection, may be readily cast with the slotted openings therein without the use of cores.

By the construction of the hinged supp ortingarm 0 above described in connection with the frame A, it will be seen that the bearing for the upper roll, D, is independent of the swinging arm, and may be readily removed and replaced as desired. By this construction the labor in fitting up the machine is materially decreased. The lower shaft, D, being of the same size throughout, may be formed from cold-rolled shafting with very slight fitting thereon. All the parts are exceedingly simple, and may be readily constructed and assembled with very little fitting, except such as may be accomplished by ordinary straightforward machinework.

It is obvious that the constructions may be considerably varied, if desired. Instead of the latch f, asuitable sliding pin or key might be used with equally good results.

If desired, several grooves might be employed in the main shaft to provide for different-sized rolls or different adjustments of the machine.

The lever d or the hand-screw c 1nay either be employed to the exclusion of the other, or both may be used, as desired.

Other modifications may be em ployed,which will readily suggest themselves to the mind of an ordinary mechanic.
