UNHED STATES PATENT- OFFICE.
- CHARLES OBERLE AND ERNST FALLER, OF NORTH TARRYTOWN, NEW
YORK, ASSIGNORS TO- MAX H. C. BROMBACHER, OF SAME PLACE.
PIPE-FORMING MACHINE.
SPECIFICATION forming part of Letters Patent No. 543,558, dated July 30, 1895.
Application filed September 30, 1392. Serial No.447,392. (No model.)
To all whom it may concern;
Be it known that we, CHARLES ()BERLE and ERNST FALLER, of North Tarrytown, Westchester county, and State of New York, have invented a certain new and useful Improvement in Pipe-Forming Machines, of which the following is a specification.
This invention relates to machines for forming pipes, such as stovepipes and the like; and it consists in a construction whereby a sheet of metal cut to the required size has the seam-1aps formed on the opposite edges, the metal turned in cylindrical form, and the seam-laps pressed together, or, in other words, completing a pipe in one machine.
Heretofore it has required one machine to form the seam-laps, another machine to turn the sheet in cylindrical form, and another machine to press the seam.
We will describe a machine embodying our improvement, and then point out the novel features in claims. 7
In the accompanying drawings, Figure 1 is a front elevation of a machine embodying our improvement. Fig. 2 is a top or plan view thereof. Fig. 3 is an end view. Fig. 4 is a view of the end opposite to that of Fig. 3. Fig. 5 is a transverse vertical section. Fig. 6 is a plan View of a portion of the machine, partly in section.
Referring by letter to the drawings,A designates the forming-roller,A the lower or. pressure roller, and A the turning-roller. All of the rollers have j ournal-bearings in the standards A extending upward from a suitable base. The bearings for the roller A are fixed, but the bearings for the rollers A and A are vertically adjustable, so that said rollers may be moved vertically.
The roller A has its bearings in blocks a. a movable in slots formed in the standards A directly above the roller A, and the roller A has its bearings in blocks 0t sliding in slots in the standards at the rear of the rollers A A. Each block has connected to it, by means of a swivel or ball-and-socket joint a an adjusting-screw of. These adj usting-screws engage in tapped holes in the top plates of the standards A and evidently by manipulating these bolts the said rollers may be adjusted the standard A At the opposite end the journal of the roller A is provided with a pinion 1) adapted to mesh with a' pinion b on the journal of the rollerA and impart rotary motion to the roller A.
The roller A is rotated by the contact of the pipe metal with it.
The roller A has longitudinal grooves O C.
formed in it. These grooves are undercut, or arranged on a tangent, to receive the edges of the sheet metal 'to form the seam-laps.
The operation of the machine as so far described is as follows: The crank-shaft is placed in gear with the wheel B, so that a fast motion may be imparted to the rollers. A sheet of metal has one edge placed in the groove 0. Then by rotating the rollers the sheet is curved transversely and a seam-lap formed. This lap is disengaged and the sheet is reversed and its opposite edge is placed in the groove 0. rollers in the reverse direction from that of their former movement the second lap is formed and disengaged from the groove 0. The two laps may now be hooked together and the crank-shaft geared with the wheel B to impart a slow motion to the rollers for pressing the seam. The rollers are now operated to press the seam between the rollers Now by a rotation of the A A and the pipe removed in a finished condition. To obviate the necessity of adjusting the roller A'to increase the pressure for pressing the seam, we may employ a presserplate. This presser-plate consists of a strip of metal 0 having inwardly-turned ends 0 journaled loosely on the journals of the roller A. When the rollers are rotated to press the seam, this resser-plate is placed between the pipe material and the roller A.
The finished pipe may be removed from the roller A by moving the said roller longitudinally until the journal is removed from the bearing-block a and tilting the end of the roller upward, as shown in dotted lines, Fig. l. During this tilting movement the block a will swing on its ball-and-socket joint. By employing the ball-and-socket joint the bearing of the roller is rendered more even than is possible when the ordinary connections are employed.
For the purpose of moving the roller A longitudinally we employ a lever C having a loose connection with the journal of said roller, (here shown as by meansof a stud or screw 0'.) One end of the lever is provided with a suitable handle, and the opposite end is fulcrumed to a stud c adjustably connect-- ed to the standard A by means of ascrew 0 extended through aslot in said lever into the stud c \Vhen the roller A is in position for forming a pipe, it is held from longitudinal movement by engaging the lever O with a detent 0 extended from the standard A as shown. lVhen it is desired to move the roller A longitudinally, for the purpose described, it is only necessary to release the screw of the block a, so that the lever C may be lifted from the detent c and then moved outward, or
the lever may be of resilient metal and spring out of engagement with the detent.
Having described our invention, what we claim is- 1. In a pipe forming machine the combination with the pressure roller and the turning roller, of the longitudinally movable forming roller having the grooves, and gearing for imparting a fast or slow rotary movement to the pressure roller, substantially as specified.
2. In a pipe forming machine the combination with the pressure roller and the turning roller, of the tilting longitudinally movable roller having the longitudinal grooves, and a pressure plate movable between the pressure roller and the turning roller, substantially as specified.
3. In a pipe forming machine, thccombination with the pressure roller and the turning roller of the forming roller movable longitudinally, a lever for moving said roller longitudinally, and the swinging bearing block for said roller, substantially as specified.
In testimony whereof we have signed our names to this specification in the presence of two subscribing Witnesses.
