IVIIIIIIAM TIIOM, OF INDIANAPOLIS, INDIANA.

FLANGlNG-NACHINE.

SPECIFICATION forming part of Letters Patent No. 398,674, dated February 26, 1889.

Application'filed March 27, 1888. Serial No. 268,714. (No model.)

.To all whom, it 71mg/ concern:

Be it known that I, W'ILLIAM THOM, ot" the city of Indianapolis, county of Marion, and State ot Indiana, have invented certain new and uset'ulImprovements in Automatic Lock- Seam Elbow Hook Flanging Machines, ot which the following is a specification.

My said invention consists of an automatic machine t'or forming a hook-flange on the edges oi' sheet-metal cylinders, such as are usedin the manufacture oi stove-pipe elbows, the edges ot which have been straighttlanged. on another machine for this purpose,

(shown in an accompanying application filed ot' even date and numbered 208,7 13,) and thus produce an elbow the sections of which are united by a lock-seam,7 as shown in Patent No. 365,652, issued to me June 28, ISST.

Referring to the accompanying drawings, which are made a part hereof, and on which similar letters ot' reife/rence indicate similar parts, Figure l is a side plan from the right. Fig. 2 is a :t'ront section from dotted line 2 2 in Fig. l. Fig. 3 lis a side plan trom the left on the dotted line 3 in Fig. 2. Fig. 4 is a top plan on dotted line l #t in Figs. l, $5, and

Fig. 5 is an enlarged section of the revolving head. Fig. o is a plan of the cranklever. Fig. 7 is a section showingI the rockpivot. Fig. S is a section of an elbow as uished by my said machine.

In said drawings, A represents the cast-iron frame, and A', A2, and A the cross-bars securin said frame together. The drivin gshalt B has its bearings in the box A, which is secured to the cross-bar Al.

On the shaft B are two pulleys, B being the idler, and B2 the drivingpulley, which communicates the power through the shaft B and bevel-gears BL Bi to the revolving head E, carrying the cone-rollers II. The head E runs around and upon the central stationary standard, D. The pinion Bi drives the spurwheel B6 on the counter-shaft- C, which is supported at each end by lug-bearings A5 A5. The cam L is also mounted on said countershatt- C, its periphery traveling on the trietion-roller K1, which is inserted between the two sides of lever K5, Fig. '7. The connectingrod KA1 is provided witlra screw-thread on its lower end and two lock-nuts, K", for adj ust ment, The upper end of said connectingrod K11 is secured to the lower end otl the crankdever K3 by pin or bolt Km. The cranklever Kii swings on a fulcrnm at K9 and secured to the lug KS, which is bolted to A. The hood K is secured to the crank-lever Kis by screw K for adjustment, and is rigidly held by lock-nuts K2.

The lower end of K is provided with a balljoint, l), and is fastened by means of screws c c and plate d, so as to permit the hood K to adjust itself to any angle, so as to fit and bear evenly on the top of the elbow-section M. The hollow hub of the head E extends down through the bridge-tree A2, and has its bearings therein and rests on the shoulder E.

The head E is provided with slots E2 for adjustment of the studs E, which support. and bear the cone-rollers II. The rollers II are held on said studs by the screws E". rlhe head F is mounted on the top ot' the central stationary standard, D, and rests on the spiral spring I, which .is supported by collar .I and set-screw J, and is confined at the top by a washer and machine-screw, F2. On the top ot the east-iron hea-d F is a steel ring, F3, which forms a seat for the elbow-section M while being operated upon by the rollers II. This ring F3 is rendered adjustable by means of the slots F5, and is secured to said head by the screws and nuts Fi.

On account of the peculiar angular shape of the elbow-sections it has heretofore been difficult, even at great expense, to procure a close-tting and uniform support all around the inside ot' said angular elbow-sections. To accomplish this I set an elbow-section on the top of the steel ring, as shown in Fig. 5, and then fill the inside (to the proper depth) with molten metal, F4, which admirably accomplishes the desired result, and as the metal, F4, wears oft it can be .readily replaced, as before. IVhen the hood K is forced down on the elbow-section M, the head F (resting on spiral spring I) yields to said pressure and slides downward on the standard D. A keyway is eut in the top of the standard I) and a corresponding one in the hollow hub F, and a splice, D', inserted rigidly in the standard D, so that the IOO head F may be permitted to slide up and down on said standard D and yet be prevented from turning by the action of the rollers H.

By means of the adjustment obtained through the slots F5 in head F the steel ring F2, with the metal, F4, can be set back, so that the throat M2 of 'the elbow-section M can be placed nearer the cone-rollers H4 at M2 and farther away at M, soas to offset and equalize the existing variation in the distance (owing to the peculiar angle of the elbow-section, the metal at M ruiming toward and the metal at M2 away from the rollers) between the metal Y and cone-rollers at M and M2.

Having thus fully described the construction of my machine, its operation may be briefly recapitulated as follows: The machine being automatic in its operation, it is only necessary for the operator to insert and remove the elbow-sections, which is easily done at the rate of one thousand per hour without fatiguing the operator. The machine is set in motion and the elbowsection inserted While the periphery of the cam L is traveling on friction-roller K10 from a to a', during which time the hood K remains in position, as shown in Fig. 3; but when the periphery of the cam at a passes over the friction-roller K10 the lever K5 is suddenly depressed by the action of the cam L, and through said lever K2 the hood K is brought down on the elbowsection M, which is thereby forced downv on the cone-rollers H, as in Fig. l, and thus the hookflange is formed and the operation completed, the spring N returning the levers and hood to former position for .repeated operations.

Having thus fully described the construction and operation of my said machine, what I claim as new, and desire to secure by Letters Patent, is as follows:

l. In an automatic lock-seam elbow hook- Hanging machine, the combination of the driving-shaft B, head E, gears B" and B5, conerollers H, vertically-moving head F and adjustable hood K, and means, substantially as described, for pressing said hood against the upper edge ot' the pipe-section, substantially as set vforth and described.

2. In a machine for forming hook-anges, the combination, with the standard D and the head E, ruiming loosely on said standard, ot" gearing rotating Asaid head, cone-collars H, mounted in said head and adjustable thereon, the head F, splined on the standard D, the spring I, adjustable collar J, and means, substantially as described, for pressing the pipesection down on the head F, substantially as described.

3. In a machine for forming hook-fianges, the combination, with the shaft B and standard D and with the gears B4 B5, of the countershaft C, gears B3 and B6, the lever K5, connecting-rod K4, the lever K2, the hook K, adj ustably mounted thereon, the head F, splined on the standard D and having a seat for the pipe-section, the cone-rollers H, head E, and cam L, substantially as described.

4. In a machine for forming hook-flanges, the combination, with the standard D, of the head E, having slots E2, the cone-rollers H, having their supports adjustable in said slots, gearing for rotating the head E, the head F, splined on the standard D, the spring I, collar J, and means, substantially as described, for clamping the pipe-section upon the head F, substantially as described.

5. In a machine for forming hook-flanges, the combination, with the standard D and with gears Bl B5, ot the head E, the adj ustable cone-rollers H, the head F, splined on standard D and having the ring F2, and cast ring F4, the spring I, collar J, set-screw J', and means, substantially as described, for clamping the pipe-section upon the head F, substantially as described.

In witness whereof I ha ve hereunto set my hand, at Indianapolis, Indiana, this 3d day of March, A. D. 1888.
