ROBERT` BRIGGS. PHILADELPHIA, PENNSYLVANIA.
Lette/rs` `Patent No. 98,020, dated Dccemlwr'fll, 1869.
tMPRovEn MACHINE FOR MAKING FERRLEUS.
The` Schedule referred to in these Letters Patent and making part of the same.
`Be it known that I, ROBERT BnrGGs, of 'Philadel- `phia, in the county of Philadelphia, and Statcof Pennsylvania,haveinvented certain new and useful V-Improvements in the Manufacture of Sockets or Fei-rules cf Wrought-Iron, and in `Machines for Making the same; and I do hereby declare the following lto he a full and exact description thereof,reference-heiligheid to theaccompauyiug drawings, making a part of this Figure 3 is` an endview of the'same machine, showing the gearing for driving the rollers.
Figure 4 is an opposite `end view of the same machine, showing the rollers, mandrel, &c.
Figure 5 is a top view of the same machine.
y'lhe sameletters indicate similar parts upon the several views, as follows:
lA A is the tube to be cut off.
B B is the socket/or ferrule.
G C, the bed-plate. D D the stands.
P E E E, the driving-gear wheels; E', the central wheel. l
F F, the pulley.
G G G', the shafts, G being thelupper shaft.
H H I-l, the rolls, H' being` the upper roll.
I I, the cutter. ,l
J J, the mandrel.
j', the collar ofthe mandrel.

K, the withdrawing-lever.
K', the hand withdrawing-lever.
7.', the connecting-link.
L, the level' to relieve the mandrel; l is the arc to i lock this lever.
M, the treadle to operate the top roller.
l m fm, the side-connecting links, which join the box or bearing of the top roller with the treadle.
N, the weight.
O, the `ball-box or hearing for one end of the top roller-shaft. i
l), the sliding box or bearing at the other end of the top rollenshaft. A l
Q, Vthe arcin which the lever K moves.
q, notch tolo'ck K".
To enable others skilled in the `art to make and use my invention, Iwill proceed to describe the same.
The usual and customary way of makin g iron sockets or ferrules has been to take a strip. of metal, of suitable width and length; to scarf or bevel cti the ends, and turn them up together; to join the ends at a welding-heat, by a hammer, upon the beak of an anvil; and to finish by swaging or rounding and sizing upon a mandrel, in a hollow bed or die, by the application of a top-swage or die with a hammer.
In my improved manufacture, I take a piece of tube, which has been either but or lap-welded, and at a welding-heat place the end of it upon and against the shoulder of t-he project-ing mandrel, in the interstice between the three rollers of my. machine. Then, by the application of the foot upon the treadle, the top roller is brought downnupon the end of the tube, the cutter making an indentation at the proper place for the length of the socket, and Vby the coutinuedcompression from the treadle, the rollers having a transverse motion given them, as shown on the drawing, the socket is cnt off, sized, by closing down upon the mandrel, and great uniformity of thickness of metal of the socket insured. After the socket is cut od the tube, the mandrel is withdrawn by the withdrmv'inglevel' K, through the hand withdrawing-lever K' and the connecting-link k.
Upon relieving the treadle, the weight which counterbalances it and the top roller and its bearings, lifts the roller, when, upon replacing the mandrel Vto its projection for making the next socket, the finished socket will be expelled from between the rollers.
It would be practicable to svage the end of a tube upon a mandrel by a hammer, which should have cutters placed in the bits or dies, to cut off the end. The hammer could be similar' to an ordinary tilt-hammer, or like the reciprocating hammer known as a Radus forge, the mandrel being drawn out by a withdrawing-lever behind, in a way similar to that hereinbefore described for the three-roller machine; but] think that sockets or ferrules of the kind I have invented can be made more satisfactorily and cheaply by the three-roller machine than otherwise.
My improved three-roller machine, for the mannfacture of sockets or ferrules, 'consists (the form in which I preferto construct it) ofthe bed-plate C C andthe stands D D, which constitute the frame-work for carrying the shafts G G G.
` These shafts have at one (or the driving) end, the
train of `gear-wheels E E E, which are driven by thecentral wheel E', (this wheel may be an external gearwheel, with the three others around it; or aninternal gear, including or surrounding the three others.)
The central wheel E has upon the same shaft or sleeve the pulley F, to which motion can be given by a belt.'
The two lower shafts, G G, run in fixed boxes or bearings in the stands D D, but the upper one, G', has a ball4 (or a l pivot) bearing at the end next the gearwheel E, and a sliding (or lifting) bearing at the end next the roller H'.
The shafts project .beyond the frame on the front (or working) end ofthe machine, and carry the rollers H H H', ,the iirst two, HH, being plain, andthe third having a cutter,1, either formed upon it or placed with it on the shaft G'.
The length ofthe shafts is so great that the slight angular motion which it is needful to give to the upper shaft G', does not interfere with the action of the gear-'wheels E E E E', nor praetieably et'eet the parallelism of the sockets when finished, although they may vary slightly in thickness.
rlhe lever to relieve the mandrel is hung by its eeriirc to the front stand, D, (locked by the aro 1,) and it supports the centre or fulcrum of the withdrawinglcrer K. lhe upper end ofthis lever K is forked, and'iu the fork the mandrel J rests, the collarj of the mandrelembracing the ends ofthe fork.
The mandrel is placed in the interstice ofthe three shafts, the front end proiecting through a hole in the stand D., between-the three rollers H H H. This end of the mandrel is tapered, and has the shoulder j, to forni a stop for the end ofthe tube from which the socket is to be made.
The withdrawlngdever K is connected by the link to the hund withdrawing-lever K', in front of' the machine.
This lever K' moves in the arc Q, and is locked by the notch q'in that are. When thus looked, the workman can use as much force as desirable in pushing;` the tube-end on to the mandrel, and after the completion of the rolling, the workman, by springing the lever K sideways ont ofthe notch q, can then operate the lever K, and withdraw the mandrel from the finished socket.
The treadle M is hung upon the bed-plate, with the connterbalance weight N at the back end, and a footpad ou the front one. To this treadle are attached the side conneetingdnks 'm m, which join the lifting-bearing of the top shaft G and roller H' and cutter I, so that the workman, by placing` his foot on the treadle, can cnt off and roll the socket, and release the same by removal of his foot. 1
I am aware that the rolling of metals transversely to the axis ofthe bar, in the interstice between three rolls, is an old device oflong-kuown use.
I am aware that a machine having rollers disposed as I have described, has been proposed and putin use sockets or ferrules upon a mandrel supportinfs,T the welded collar, which had. previously been made from a strip of metal, (see Lon-don Engineer, vol. xxi, p.176;) but What I claim as my invention, and desire to secure by Letters Patent, is-
l. The combination of the annular cutter with the swaging-roll, and of' these with the supporting-rolls and mandrel, as herein described, for the. manufacture of sockets or il'errules ofwrought-iron, ii'om tubes previously either but or lap-welded, by cutting,r oli" the suine, simultaneously with the swaginbnr or closing down upon a mandrel, as hereinbefbre described1 2. The arrangement oi the mandrel J, in combina tion with the rolls H H H and the withdrawingdever K, substantially as and for the purpose described.
