ATTORNEY UNITED STATES PATENT OFFICE.
FREDRIGK HILDEBRANDT, OF NEW YORK, N. Y.
MACHINE FOR BEADING STOVE-PIPE ELBOWS.
SPECIFICATION forming part of Letters Patent No. 247,347, dated September 20, 1881.
Application filed October 18, 1880. (No model.)
To all whom it may concern Be it known that I, FREDRIoK HILDE- BRANDT, of the city, county, and State of New York, have invented certain new and useful Improvements in Machines for Beading Stove- Pipe Elbows, of which the following is a specification.
This invention relates to an improved machine l'or heading the edges of the sections of stove-pipe elbows, so that this work may be accomplished around the entire edge of a section in a uniform and rapid manner without requiring the exercise of special skill, as requiredin working the beading-machinesin general use.
In the accompanying drawings, Figure 1 represents an end elevation, and Fig. 2 is a side elevation, of my improved machine for beading the sections of stove-pipe elbows.
Similar letters of reference indicate corresponding parts.
A in the drawings represents the supporting-frame of my improved beading-machine, which is provided with the customary upper and lower beading-rolls, B B, which are revolved by means of a hand-crank and transmitting-gearingin the usual manner. The upper beading-roll, B, is adjusted higher or lower by means of a tap crank and screw pressing upon the journal-bearing of the shaft of the upper roll. An adjustable gage, 0, serves to regulate the distance of the head from the edge of the pipe-section, as customary in this class of machines, The lower beading-roll is providedwith a torwardextending guide-cylinder, B as shown clearly in Fig. 2. In place of the same a loose roll placed upon the forward-extended shaft of the lower roll, B, may be used. An inclined guide-plate or apron, D, is rigidly attached to the lower part of frame A, vertically below the lower beadingroll, B. The lower beading-roll, B, is provided with an annular raise, a, at the inner end, having an angle of about forty-five degrees or less, and the upper roll, B, with an annular groove, b, of corresponding angle and depth, as shown in Fig. 2. The raise a and groove I) produce the bending of the bead by one operation. This feature secures, in connection with the extension guide-cylinder and fixed apron, the beading of an elbow-section by one revolution of the same between the rolls.
In heading the section of a stove-pipe elbow the wider portion of the same is first introduced between the beading-rolls and allowed to rest upon the extension cylinder or roll B By turning the actuating-crank the edge of the section is carried along the gage O and between the beading-rolls and is beaded, the workman simply holding the section of elbow in contact with the sliding gage C. When by the rotation of the beading-rolls the narrower half of the pipe-section is passed through between them the wider part t'orms contact with the lower guideplate or apron and is guided along the same, so as to allow the proper formation of the narrower partof the elbow-sec tion. In this manner an elbow-section can be beaded in an accurate and uniform manner, without requiring any special skill in holding the same for the proper action of the beadingrolls thereon.
Having thus described my invention, Iclaim as new and desire to secure by Letters Patent- 1. As an improvement in beading-machines, the combination of a pair of beading-rolls, B B, the lower one of which is provided with a forward-extending extension cylinder or roll, B adapted to support the elbow-section, an adjustable gage, O, and a fixed inclined gageplate or apron, D, placed below the lower beading-r0ll, substantially as described.
2. In a beading-machine, thecombination of the lower beading-roll, B, having an annular raise, a, made at an angle of fortyfive degrees or less, the upper roll, B, having an annular groove of corresponding concavity, said lower.
roll being provided with a forward-extending extension cylinder or roll, B adapted to support the elbow-section, an adjustable gage, O, and a fixed inclined gage-plate or apron, D, placed below the lower beading-roll, substantially as described.
In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 13th day of October, 1880.
