Description
C. H. STAHMER BRAKE TTORN o.
iiatented lian9 2G,
a Werner CARL H. STA-IMER, O
SONORA, CALIFORNIA.
BRAKE.
Application led October S, 1923.
To UN 1v/7i ont it muy concern.'
Be it known that i, Cant. Sfmrirrnn, a citizen ot the United States, and a resident ot Sonora. county ot Tuolumne, 'tate of California, have invented a new and useful Brake, ot' which the toll-owing is a specification.
This invention relates to brakes as used on vehicles, or revolving machinery generally, but has particular' reterence to brakes on automobiles as used en the outer surtace of brake drunis secured to the wheels thereof.
The principal objects ot n'iy invention are to produce a contracting band brake adaptable to the use mentioned which will give a more-powerful and more unitorm grip on the brake drinn than the band or externa brakes now in use, and this in a structure ot great simplicity.
i achieve niy objective in the construction shown in the drawings hereto, and in which:
Figure l is a side elevation, partly in section, showing my brake in position around the outer surface of a brake drinn.'
Figure Q is a cross section or' Figure l along the line 2-2 showing one of the guidingl incinbers tor the band;
Figure S is a section along the line of Figure l showing one of the pressure distributing rollers; and
Figure iv is an enlarged perspective sketch showing the slotted anchorage end of the hand with the wrapped portion extending therethrough.
By a glance at Figure l it will be seen that iny new arrangement consists essentially ot a brake band wrapping entirely around the drinn, passing the anchorage end and again inaking a turn around the druin outside of the tirst wrapping producing a double or superimposed coil effect.
rllhe brake drinn is designated (l). the contracting band (2) which is suitably lined with brake lining secured to the band by rivets The anchorage end is designated (5) and is anchored at (6) to the vehicle or inachine (not shown).
The anchorage end is apertured at (7), as shown best in Figure 1li, and reinforced by the anchorage lug aseshown at (1G) and the tree end is notched or reduced in width as shown at (8) to tree-ly pass the aperture, after which it is wrapped around the tirst wrapping as shown at (9) spaced theretron'r Serial No. 667,300.
by a. plurality oitl pressure rollers (l0) carried on brackets (ll) secured to the secondary wrapping and is guided laterally by brackets (l2) secured to the first wrapping. rThe final or tensioning end ot the band is secured at (l) to any suitable tensioning ineinber, here shown as a brake rod (14) having an adjusting turn buckle (l5).
Figure 3 shows clearly in cross section the pressure rollers (l0) bearing on the first wrapping ot the brake band, and Figure 2 shows the outer ,vrapping guided in the brackets ln Figure l it will be observed that the rollers (10) and rivets are so spaced relative to each other that the rollers have a smooth unbroken surface of the band to roll on in tightening the brake as the band is pulled by the rod (le) to actuate the brake. ln Figures l and 2 are shown ingers (17) extending troni brackets l2) and overlapping the drinn edge to prevent the brake working over bodily into the spokes ot the wheel.
The inaterial of which iny brake band is uiade is preferably spring steel. so that it will contract evenly against the drinn when the rod is pulled and release evenly when the rod is reversed or released, and also so the outer wrapping will exert siiitiicient pressure on the rollers without undue tiattening between the rollers where it is unsupported thereby. YVhile show rollers tor applying the pressure to the inner troni the outer wrapping it is apparent, these could be siniple blocks, or he dispensed with altogether, but the use oi rollers as shown greatly reduces the friction otherwise developed.
in operation, iny band when pulled contracts upon the drinn in the usual way but by reason ot the extra wrapping and rollers it is further forced against the drinn evenly all around, thus greatly increasing the effectiveness ot the brake by utilizing the entire effective braking surtace ot the lining in.- stead ot' wearing it principally at two places only as with the bands in ordinary use.
l claim:
l. ln a band brake, ai drinn, a band wrapped therearound in overlapping layers, rollers between and spacing the layers and brackets extending 'troni one ot the layers revolvably supporting the rollers.
2. ln a band brake, a drinn, a band wrapped therearound in overlapping layers, rollers between and spacing the layers and brackets extending from one oi the layers revolvably supporting the rollers, and means for laterally aligning the layers.
3. In a band brake, a drum, a band 5 Wrapped therearound in a double overlapping relation, brackets carried by the outer Wrapping, rollers rotatably carried by the brackets and arranged to bear against the inner Wrapping upon tightening the band.
4. In a band brake, a drum, a band wrapped therearonnd in a double overlapping relation, brackets secured to the inner Wrapping for laterally guiding the outer Wrapping, brackets carried by the outer Wrapping, rollers rotatably carried by the bracketsr and arranged to bear against the inner Wrapping upon tightening the band.
5. A contracting band for a brake druni, said band being of resilient metal notched for passing itself to forni a double concentric loop, brake lining riveted to the inner side of the inner loop and rollers carried by the outer loop spaced to bear on the inner loop between the rivets.
