UNITED STATES MELVIN STEIN GER, OF PO TTSTOWN, PENNSYLVANIA.
ANGLE SPLIT RING.
Application filed August 28, 1924. Serial No. 734:,698.
My invention relates and is illustrated in the accompanying drawings in its application to the stamping of angle split rings such as are especially adapted for use in band brakes. It has been customary heretofore to make these angle rings of cast iron which is not altogether satisfactory, and in the few instances where they have been stamped from sheet steel discs are first punched and out of each of said discs is thereafter punched another smaller disc leaving a flat ring which may then be re-stamped to provide a flange or angle form in cross-section. This method of procedure, however, is not only very wasteful of material but also of labor, and also results in the construction of an angle band or split ring which is not sufliciently uniform. According to the preferred embodiment of my invention, when a split angle band of the character desiredis to be made, a long narrow strip of material which is first rolled to the proper diameter is thereafter stamped in two operations, the first of which partly turns the flange, and the second of which completely turns the flange forming an angle split ring in more uniform manner, much more quickly and with practicaly no waste of material, also producing a product which is practically clear of all irregularities and of great uniform strength.
In the accompanying drawings, I have illustrated in Fig. 1 in longitudinal section, an application of a split ring in position in a suitable form of die showing the manner of making the first turn of the flange thereof. Fig. 2 indicates a cross-sectional View of the product so formed, and Fig. 3 shows a strip of unformed metal in plan view. Fig. 4 is a further View of the dies in position making the second operation. Fig. 5 is a cross-sectional view of the ring after said second operation. Fig. 6 is a front elevation of a band brake formed as described. Fig. 7 is a cross-section on the line 7-7 of Fig. 6 looking from left to'right thereat. Fig. 8 is a stamping for the loop of said hand brake, and Fig. 9 a final stamping thereof, Fig. 10 being a view from right to left at Fig. 9.
11 indicates the base block of the die which is provided with a ring 12 normally projected upwardly by any suitable means such as the springs 13 around the bolts 14 which are preferably secured in the base block 11 in any convenient manner as shown.
The top of the base block is circular in crosssection and is provided with an annular seating for the split ring or hoop of steel such as 15. 16 indicates the upper part of the die which it will be observed continues upwardly with a bevel or angle 17, preferably at about forty-two degrees. When the split ring 15 is placed in position upon the block 11 as shown in full outline and the upper part 16 of the die is brought down upon the same, the upper portion of the ring is bent inwardly as indicated at 18, producing a slight curvature, as shown to better advantage in Fig. 2. After the bands have been thus shaped, the upper part of the die is changed, and the upper part 19 shown to advantage in Fig. 4, is substituted. This part of the die it will be observed is provided with a flat portion 20 at right angles to the vertical wall of the band, and when the same is brought down upon the band as shown in Fig. 4, the flange is formed at right angles as indicated at 21 in Fig. 5. In a band thus formed it will be found that the walls are substantially uniform throughout showing practicaly no wrinkles or crowding of material, and are of uniform strength.
In assembling the band brake, two split angle rings such as 22, 23 are associated side by side as shown to advantage in Fig. 7, which is the usual practice. In oining them, however, they are welded at spots such as indicated at 24, thereby making the application of rivets or other fastening means unnecessary, although if desired the end piece such as 25 may be riveted as shown at 26. 27 indicates the loop which is usual for attachment of the band and is preferably made with bifurcated ends 28/29 as shown to advantage in 95 Fig. 8. This is a flat stamping which in the second. operation is formed as shown in Fig. 9. The forked- like ends 28, 29 serve to allow for the passage of the flange 30 of the split ring when applying the loop, and the 100 loop may be spot welded as indicated at 31 to the other flange 32 of the ring. 33, 34: indicate the usual asbestos contacting surface for the band which may be applied in the usual and well known manner.
f course it will be understood that various modifications may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.
I claim 1. The band portion of a band brake mechanism comprising a pair of flanged rings secured parallel, and a loop substantially at the centre thereof upon the inside extending over opposite sides of said adjacent flanges and secured upon the inside of the rim thereof.
2. The band portion of a hand brake mechanism comprising a pair of flanged rings secured parallel, and a loop substantially at the centre thereof upon the inside extending over opposite sides of said adjacent flanges and secured upon the inside of the rim thereof, said loop formed out of an integral piece of metal having bifurcated ends 3. In a hand brake, a pair of split flanged rings spot welded together between adjacent flanges said flanges separated substantially at the center and loop at said separation.
In testimony whereof I hereunto afiix my 20 signature.
MELVIN STRINGER.
