METAL-WORKING- MACHINE.

Specification of Letters Patent.

Patented Sept. 14, 1909.

Application filed January 4, 1909. Serial No. 470,670.

. To all whom it may concern.'

Be it known that I, PATRrcK J. HAVEY, residing at Swissvale, in the county of Allegheny and State of Pennsylvania, a citi- Zen of the United States, have invented or discovered certain new and useful Improvements in Metal-"Working Machines, of which improvements the following is a specification.

The invention described herein relates to certain improvements in apparatus for upsetting a portion of the end o a pipe, spreading such upset portion to a plane at right angles or approximately at right angles with the axis of the pipe, thereby forming a flange and then facing such flange portion, said several steps forming parts of a continuous operation.

The invention is hereinafter more fully described and claimed.

In the accompanying drawing forming a part of this specification Figure 1 is a top plan view of my improved apparatus; Fig. 2 is a sectional elevation on a plane indicated by the line II-II Fig. 1; Figs. 3 and 4 are sectional views illustrating the construction of the chuck carrying the parts directly operative on the pipe to effect the upsetting, iianging and facing operations; Fig. 5 is a sectional detail view showing the thrust bearing carrying the upsetting, flanging and facing head, and other parts adj acent thereto; Figs. 6, 7 and 8 are detailed views illustrating the several steps effected in the operation of my improved machine.

In the practice of my invention, suitable means such as a fluid pressure cylinder l is secured to or in proper relation to guideways 2. A thrust block 3 is secured by a bracket 4 to the end of the ram 5 of the fluid pressure cylinder and around this thrust block is arranged a sleeve 6 engaging the thrust block as against any longitudinal movement relative thereto but free to rotate freely on the thrust block as hereinafter described. The sleeve 6 is provided with lugs 6a adapted to engage lugs 7 on the face plate 8 of a chuck carrying the tools operative on the pipe. This chuck as clearly shown in Fig. 3 is mounted in the sleeve 9 provided with diametrically arranged lugs 10 and 11. One of these lugs is provided with an eye for the reception of a guide rod 12 while the opposite lug 11 is provided with a hook adapted to engage the opposite guide rod 13. This construction permits of the turning of the chuck to one side for the insertion and removal of pipe. The pipe to be operated on is held by clamping

jaws

14 and 15 mounted on the

rods

12 and 13, the upper section ofl the clamping jaws being weighted so that the upper section will readily swing up out of the way when it is desired to insert or remove the tube to be operated on.- A shaft 17 is so mounted in the ram 5 and thrust block 3 as to be capable of rotation and longitudinal movement therein. This shaft is provided at one end with a beveled pinion 18 adapted to engage correspondingly shaped pinions in the chuck as hereinafter described. This shaft has a pinion 19 mounted thereon, said pinion adapted to intermesh with a pinion 20, the latter also intermeshing with a pinion 21, both pinions being carried by a swinging frame 22 loosely mounted on the shaft 17.

On a driven shaft 23 is mounted a gear wheel 24 which may be constantly or intermittently driven andwhich will also intermesh with either one or the other of the pinions 20 or 21. lBy swinging the frame so pinion 20 will engage with gear wheel 24, the shaft 17 will be rotated in one direction. When the frame 22 is swung so as to cause the pinion 21 to engage the gear wheel 24 a reverse rotation will be given to the shaft 17 as the motion imparted to the pinion 21 is transmitted to the shaft through the

pinions

20 and 19. The shifting of the frame 22 can be effected in any suitable manner as for example by a lever 25 provided with a suitable latch lever 25a, whereby it may be locked in either of its positions. The thrust sleeve 6 is provided with a toothed rim 26 engaging the gear wheel 27 on the shaft 23.

When it is desired to operate on the pipe which has been previously clamped in the

jaws

14 and 15, the ram 5 of the cylinder 1 is caused to move forward thereby pushing the end of the thrust sleeve 5 against the face plate 8 of the chuck and thrusting such chuck into operative relation, as hereinafter described, with the end of the pipe. The bevel pinion 18 on shaft 17 engages when the shaft is shifted as hereinafter stated with the beveled pinions 29 on the ends of shafts 30 in the chuck. These shafts are provided at their outer ends with pinions 31 intermeshing with pinions 32 on the threaded shafts 33. On these shafts are mounted nuts 34 preferably having conical bosses or projections 35 forming bearings for the rollers 36 which operate to upset and Y Y spread the end of the pipe. The nuts V34 are provided with.v lugs which engage with and are held from-turning by guides 37 in the chuck. These several parts are so constructed and arranged that when the shaft 17 is rotated in one direction the nuts will be moved inwardly and when in the opposite direction will be moved outwardly e in a necessary it is preferred that the rollers which are loosely mounted on the screwy shafts 33 should be held against the nuts by springs 3S so that they will follow the nuts andbe in proper position when the latter are adjusted, and the sections held in operative relation to each other. In ways 39 arranged at right angles withV the ways 37 are mounted'blocks 40 adapted to be shifted by the screws 41 to the desired position as hereinafter stated, and carrying rollers 42 loosely mounted on pins projecting from the blocks 40.

, The end of afpipe vhaving been properly heated, the pipe is placed in position between

theV jaws

14 and 15 with a desired lengthprojecting from the jaws 14. An

anvil ring 43 is then slipped over the projecting end of the pipe, and the nuts 34 and lrollers 36 having been soadjusted relative to each other and the diameter of the pipe,

that the neck or upsetting portion a of the rollers will bear upon the end of the pipe, the chuck is forced toward the pipe by the outward movement of the ram 5. The thrust sleeve is then rotated and with it the chuck so as to carry-the rollers around the end of the pipe. The chuck is moved forward to upset the portion of the pipe between the anvil ring which bears against vthe clamping jaws 14 and the rollers 36 by the ram of the cylinder 1. At the same time that therollers Yare adjusted as above stated, the blocks 40 are also ,adjusted so that the rollers 42 will hear against the inner periphery of the pipe during the upsetting operation, so that. all the enlargement of the pipe during such upsetting will occur outwardly. After the desired upsetting or thickening of the metal has been efected, the shaft 17 is shifted longitudinally so that the pinions 18V will engage the pinions V29 and the frame 22 is swung so as to bring the pinion 20 into engagement with the gear wheel 24. By the rotation of the shaft 17, the nuts 34 and rollers 36 will be gradually moved outward, forcing the yconical portions b of the rollers to operate on the previously thickened por- 'tion of the pipe, and spread the thickened metal out radially to. form a Hange, the inward movement ofthe chuck against the pipe being continued. By these conjoint movements the thickened portion of the pipe 'ssaesi will be bent into the form of aV flange as Y shown inFig. 8. In order to face the flange thus formed cutting tools 44 are secured to the nuts 34 in such position that when Vthe nuts are moved outwardly as heretofore de scribed'these tools will be caused to traverse the outer face of the Hange formed on the end of the pipe.

After the completion of thepipe, the shaftY 17 is withdrawn and the ram 5 with Ythe parts carried thereby retracted by anysuit` able means for example anauXiliary Huid pressure cylinder '4G having its ram conf` nected by `rods 47 to lugs 4S on the head of the ram 5. i

By making therollers 36 in sections necks a of different lengths to Ysuit the thickness to be produced in upsetting can be readily A placed in position, and the entire roller need not be replaced. The disk portion o of the rollers will serve as a stop by bearing against the anvil 43.

I claim herein as my invention 1. In a tool for Hanging pipe, a chuck i" y' provided with rollers, in combination with means for rotating the chuck, means for moving the chuck in the direction-ofthe Y length of thepipe and thereby effecting an Y.

upsetting of the wall of the pipe adjacent to its ends by thej actionof the rollers thereon the end of a pipe, means for adjusting the Y rollers toward and from each other, and with adjustable rollers adapted yto bear against the inner periphery of the Ypipe in combina-tion with means for movingV the chuck in the direction of the length of the )i e means for rotatino` the chuck. and 1 C means for moving the interiorly operating rollers to form the flange.

4. In a tool for HangingA pipe, a chuck provided with rollers adapted to bend the end wall outwardly to form a flange, cutters forV facing the Hange and with means for moving the rollers and cutters outwardly during the rotation of the `chuckin combination with means for rotating the chuck. Y i
