THOMAS C. BELDING, OF CANTON, OHIO, ASSIGNOR TO THE OANTON'STEEL ROOFING COMPANY, OF SAME PLACE.

TUBE-MAKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 445,517, dated January 27, 1891.

Application filed June 13, 1890. Serial No. 355,317. (No model.)

T at whom it may concern:

Be it known that I, THOMAS C. BELDING, a citizen of the United States, residing at Oanton, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Forming-lvlachines; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings,

:0 making a part of this specification, and to the letters of reference marked thereon, in which- Figure 1 is a perspective view showing't-he machine complete. Fig. 2 is an end view at Z. Fig. 3 is a transverse section on line w 00, Fig. 1. Fig. t is a transverse section through line y y, Fig. 1. Fig. 5 is an end view of the opposite end from that shown in Fig. 2. Fig. 6 is a view of the different-sized gear-wheels and crank. Fig. 7 is a view of a portion of the table. Fig. 8 is a detached view of the yoke and gear-wheels. Fig. 9 is a View showing the swinging-roll connection.

The present invention has relation to formin g-machines designed and calculated to form eaves-troughs, pipes, and conductor-pipes; and its nature consists in the different parts and combination of parts hereinafter described, and particularly pointed out in the 0 claims.

Similar letters of reference indicate corresponding parts in all the figures of the drawings.

In the accompanying drawings, A repre- 5 sents the legs orsupports, which are substantially of the form shown and as illustrated in Fig. 3. Their top or upper ends are united together by means of the cross-bar or bridge a, which cross-bar is formed integral witlrthe 4o legs or supports A.

To the top or upper ends of the legs or supports A are securely attached, by means of the cap-screws b or their equivalents, the longitudinal bars B.

5 To the top or upper edges of the longitudinal bars B are seated the housings C, said housings being securely held in proper position by means of the cap-screws h or their equivalents. The housings O are provided with the flanges 71 which flanges embrace the outer edges of the longitudinal bars B and are for the purpose of assisting in holding the longitudinal bars in proper position and relieving the cap-screws from any lateral strain.

Within the housings O are located the journal-boxes D and D, which are held in the desired position by means of the side flanges b Within the boxes D and D are located the bushings c, which bushings are located as illustrated in Fig. 3 and are for the purpose of receiving the ends of the rolls E and E.

To one end of the forming-rolls E are securely attached the cog-wheels d, which are for the purpose of communicating rotary motion to each of said rolls E by means of the crank d or its equivalent. The forming-rolls E are held in proper relation to each other by means of the screws (1 the top or upper ends of said screws being provided with the hand-wheels For the purpose of parting the forming-rolls E when released the springs e are provided, which springs are located between the boxes D, said springs being recessed into said boxes, 7 5 substantially as illustrated in Fig. 3.

The cap F is attached to the top of the housings O by means of the cap-screws b or their equivalents.

To the side of the forming-rolls E is 10- 8o cated the adjustable forming-roll E, which is journaled to the sliding boxes D. These sliding boxes D and the adjustable formingroll E are held at the desired point of adj ustment by means of the screws G and G.

For the purpose of adjusting the formingroll E up or down, and at the same time keeping the said roll in line longitudinally with the forming-rolls E, the bottom or lower ends of the screws G are provided with the beveled gear-wheels g, which mesh with the beveled cog-wheels g, located on and attached to the shaft 71., thereby causing said screws G to rotate in unison when the shaft h is rotated.

For the purpose of causing the wheels 9 and g to mesh as the vertical screws G move up and down, the yokes h are provided, which yokes are located substantially as illustrated the conneeting-links J.

in the drawings. The bottom or lower ends of the yokes h receive the shaft h, and the top or upper ends or portions receive the lower portions of the screws G.

Vhen the forming-roll E has been adjusted to the desired point with reference to the forming-rolls E, the forming-roll E is securely clamped by means of the set-screws G.

For the purpose of communicating rotary motion to the adjustable forming-roll E the cog-wheel H is provided and is securely attached to one of the forming-rolls E in any convenient and well-known manner, which wheel meshes with the cog-wheel H, as illustrated in Fig. 5, and for the purpose of communicating rotary motion to the forming-roll E at different points of adjustment differentsized wheels H are provided, the size of the wheel corresponding with the degree of adj ustment of the forming-roll E.

The shaft I is located substantially as illustrated in the drawings and is journaled to the brackets I or their equivalents.

To the shaft I are securely attached the operating-levers 1 which operating-levers are preferably located as illustrated in Fig. 1.

To the shaft I are attached the arms J, and to the free ends of these arms are attached The opposite ends of the links .l are attached to the connecting-bars .1. One end of the conneeting-bar J 2 is attached to the lower forming-roll E, and the other end is attached to the swinging roll K.

For the purpose of preventing the connecting-bars J from interfering with the sheet of metal said bars are recessedinto the formingrollE and also into the swinging roll K. The swinging roll K is located as illustrated in the drawings and is for the purpose hereinafter described.

For the purpose of preventing the lower forming-roll E from springing while in use the rolls K are provided, which are held against and in contact with the said lower forming-roll E by means of the bracket K which bracket is preferably attached to the plate K For the purpose of preventing the adjustable roll 1 from springing the rolls L are provided, which rolls are j ournaled to the sliding bracket L. This sliding bracket extends downward and passes'through the plate L and the center bar or bridge a.

At about the center of the machine I locate a vertical screw G formed and operating enactly the same as the end screws G from the shaft it through pinions g g. This screw bears against the bracket L as clearly shown in Fig. 4.

\Vhen the adjustable formin g-roll E is elevated by means of the screws 6%, the center screw will elevate the bracket L, together with the rolls L, and when said adjustable forming-roll is lowered the bracket L will follow down the adjustable forming-roll by its own weight and the weight of the forming-roll E thereby causing the rolls L to follow the movements of the adjustable forming-roll E.

For the purpose of providing a counterweight for the swinging roll K the weight M is provided, and is located substantially as illustrated in Fig. 1. This weight M is attached in any convenient and well-known manner to the free end of the bar N, which bar is fulcrumed at or near its center to the 'barN, which bar is securely attached to some part of the frame, such as one of the longitudinal bars B.

To the opposite end of the bar N is attached the bottom or lower end of the link N the upper end of said link being attached to the arm 0, which arm is securely attached to the shaft I.

For the purpose of locking the sliding bracket L at the desired point of adjustment the set-screw c' is provided, which set-screw is located substantially as illustrated in Fig. 4.

The table P is located in front of the forming-rolls E and is securely attached to the longitudinal bars B by means of the brackets P or their equivalents.

In use, when it is desired'to form an eaves trough or pipe, the sheet of metal is placed upon the table P, at which time the formingrolls E are rotated, thereby drawing the sheet of metal between said rolls, at which time the swinging roll K is elevated by means of the operating-levers I and their attachments, thereby elevating the outer portion of the sheet of metal, which in turn causes said sheet of metal to follow up and pass between the adjustable forming-roll E and the upper forming-roll E, 1 thus converting a strip of metal into the desired shape to form an eavestrough pipe or water-conductor pipe.

It will be understood that by providing the swinging roll K the sheet of metal will be bent upward uniformly from end to end.

The regulating-screws R are located substantially as shown in Fig. 1 and are for the purpose of providing stops for the operatinglevers 1 It will be understood that these regulating-screws R-will limit the downward movement of the operating-levers I and when it is desired to form eaves-troughs of small diameters it is necessary to bring the.

swinging roll K nearer to the forming-rolls E than 11: 1s when eaves-troughs of large diameter are to be formed. lVhen it is desired to bring the swinging roll K close to the forming-rolls E, the regulating-screws R are lowered, thereby permitting the operating-levers I to be forced farther downward.

The swinging roll K is designed and calculated to rot-ate as the sheet of metal from which an eaves-trough or pipe is to be formed passes over said roll; but it will be understood that a non-rotating roll or bar may be used and the same result accomplished so far as the bending up of the outer portion of the sheet of metal is concerned. I

Having fully described my'invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a metal-forming machine, the combination of forming-rolls E E, the adjustable forming-roll E, the sliding bracket L, carrying the roll, the swinging roll or bar K, located at the entering side of the machine, and the operating-levers 1 substantially as and for the purpose specified.

2. The combination of the shaft I, having attached thereto the operating-levers 1 and the arms J, the connecting-links J and J and the swinging roll K, substantially as and for the purpose specified.

3. The combination of the shaft 1, having attached thereto the arm J, the connectinglinks J and J the swinging roll K, the counter-Weight M, the bar N, fulcrumed at or near forming-roll E, and the roll-carrying bracket L, of the vertical screws G G operating on the forming-roll and the bracket, and the shaft h, rotating said screws through bevelgear g g, substantially as described.

In testimony that I claim the above I have hereunto subscribed myname in the presence of two witnesses.
