MELVIN STRINGER, OF NEW. YORK, N. Y.
BAND BRAKE.
Application filed Octolier 19, 1925. Serial No. 63,234.
My invention relates to improvements in band brakes, and more particularly has ref 'erence to and is illustrated in the accompanying drawings in its application to a split band brake, which may be an internal band, such as are commonly used in automobiles and is inthe nature of a modification of my co-pending applicatiOn S. N. 734,935.
According to a preferred embodiment of my invention, the brake is operated at the I split or opening in the band insuch a man- ,ner that the trailing side or end of the band is advanced over the opposing side in applying the brake, so as to apply the band more uniformly to the drum throughout its length, thereby increasing its efficiency and braking power.
ltn the accompanying drawings, I have illustrated in lFig. 1 in perspective a suitable form ofband brake embodying an application of my invention. Fig. 2 is a similar view illustrating a modification. Fig. 3 is a broken section illustrating the arrangement of the separating strips.
1 indicates a steel band which is split or separated at the ends as indicated at 2 and which is provided with a suitable bearing or support 3. I
-ln Fig. 2 a two-part reinforcing web 4 and 5 is shown and may be used, the same preferably being secured to the band by cates a spring across the split of the band.
8and9 indicate links pivotally mounted as shown in the toggle 10, said toggle being suitably secured to the usual pin 11 for rotating the same.
The link and toggle pins 12, 13 are usually mounted equally distant from the center of rotation of the toggle 10, but according to the preferred embodiment of any invention, and assuming that the vehicle is traveling from left to right, looking at the drawing, the pin or bearing 12 is at a slightly greater distance from the center 11 than the pin or bearing 13. This causes the end of the band pointing in the direction of rotation of the Inplace of the toggle, other means may be employed for opening theband, such for instance as the cam 10 shown in Fig. 2 and in such case the adjacent ends of the band may be turned in and backed by the webs 4 and!) as shown. Also in the modification shown in Fig. 2, the ends of the spring 7 may be secured in the reinforcing webs as shown instead of to the link bearings 14, 15 shown in Fig. 1..
Referring more particularly to Fig. 3, it will be seen that the separating strips 6 are spot welded to the inside of the band 1, and to the periphery of the reinforcing piece 4, as shown at 16, 17, leaving a space between said pieces and said band.
of 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. In a band brake of the class described, a substantially fiat steel band, and substantially fiat steel reinforcing webs substantially at right angles thereto and at the center of one side thereof, said webs separated from said band providing a space therebe tween.
2. In a hand brake of the class described, a substantially flat steel band, and substantially flat steel reinforcing webs substantially at right angles thereto and at the center of one side thereof, said webs separated from said band providing a space therebetween and said webs secured to said band.
3. In a band brake of the class described, a substantially flat steel band, and a twopart substantially flat steel'reinforring web substantially at right angles thereto, said band turned in at the ends thereof and said web abutting said turned-in ends and sepaa rating pieces between said web and said band.- 7 1 4. In a band brake of the class described, 5 a substantially fiat steel band, and a substantially fiat two-part steel reinforcing web substantially at right angles thereto, said band turned in at the ends thereof and two of the ends of said web abutting said turnedin ends and a spring adjacent the ends of 10 said band and anchored to said webs and separating pieces between said web and said band.
In testimony whereof I hereunto aflix my signature.
MELVIN STRIN GER.
