G. NAUMAN. MACHINE FOR FORMING RIDGE BARS.
(No Model.)
No. 421,961. Patented Feb. 25, 1890.
UNITED STATES ATENT OFFICE.
GEORGE NAUMAN, OF CANTON, OHIO.
MACHINE FOR FORMING RIDGE-BARS.
SPECIFICATION forming part of Letters Patent No. 421,961, datedFebruary 25, 1890.
Application filed May 1, 1889- Serial No. 309,261. (No model.)
To all whom it may concern:
Be it known that I, GEORGE NAUMAN, a citizen of the United States, residing at Canton, in the county of Stark and State of Ohio, have invented certain new and useful In1- provements in Machines for Forming Ridge- Bars; 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, making a part of this specification, and to the letters of reference marked thereon, in which Figure 1 is an isometrical view showing the different parts properly located. Fig. 2 is a view of the rear end of the sheet forming device. Fig. 3 is a view of the front end of the sheet-forming device. 4: is aside elevation of the sheet-forming device. Figs. 5 and 6 are side elevations of the different rolls. Fig. 7 is a side view showing the machine complete. Fig. 8 is a view of the deliveryrolls, showing their gearing. Fig. 9 is an end view of a ridge bar properly formed.
The present invention has relation to machines for forming ridge-bars; and it consists in the different parts and combinations of parts hereinafter described, and particularly pointed out in the claims.
Similar letters of reference indicate corresponding parts in all the figures of the drawings.
In the accompanying drawings, A represents the base-frame, which may be substantially of the form shown in Fig. 1. To one side of the base-frame A is journaled the shaft a, which shaft is provided with the screws 7), which are for the purpose of communicating rotary motion to the difierent rolls by means of the screw wheels B. The rolls 0 and G are calculated and designed to bend or curve a sheet of metal into the form shown in Fig. 5, leaving the straight flanges or portions at The rolls D and D are provided with the V-shaped flange and groove 0 c, which are for the purpose of forming a sheet of metal into a V shape, as illustrated in Fig. 6, at which time it enters the mouth of the formingbar E. The forming bar or Within the bar or block E is located the bar or guide cl, to which bar or guide d is attached the flaring block (Z The bar or guide 01' and the flaring block (l are securely held in proper position by means of the arm 6 or its equivalent. The block E is securely held in proper position by means of the post or standard f, which is attached to the frame A in any well-knownmanner. The delivery end of the tapered openingdis round, as illus* trated in Fig. 2, and forms the bead g. It will be seen that as the sheet of metal is forced or pushed through the opening (Z and past the guide cl and block d the head 9 and the 6 5 flanges g will be formed. Itwill also be seen that the guide cl will prevent the sheet from buckling.
For the purpose of causing the sheet to be conveyed after it has passed through the ma- 7o chine proper, the grooved rolls F are provided, and are located as illustrated in the drawings. Rotary motion is conveyed to the roller F by means of the gearavheels F It will be understood that ridge=bars can be formed of any desired length.
For the purpose of holding the rolls 0, C, D, and D in proper position, the'housings G are provided, which are attached to the base A in any well-known manner.
Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. The combination of the frame A, the bending-rolls O, C, D, and D ,the rolls 0 and 0 located in advance of the rolls Dand D and in line with each other, the bar or block E, provided with the tapered opening (Z, the guide (1'', centered therein and carried by the flaring block (1 and means for holding said the screws b, the wheels B, the bending-rolls O and C, D and D, the pair of rolls 0 and 0 being located in advance of the rolls D and D, the block E, provided with the tapered 5 opening d, the tapered block (1 having attached thereto the guide 01, centered in the opening d, and means for supporting the for rotating said delivery-rolls, substantially 1o as and for the purpose specified.
In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
GEORGE NAUMAN.

JAMES STEEN, FRED W. BOND.
