`- To all 'whom t may concern A Be it known that we, EDWARD B. H AFNER and JOHN T. Renners, citizens of the United States, residing at St. Louis, Stateof Misl souri, have `invented certain new and useful Improvements in Brake-Bands, of which the following isa full, clear, and exact description, reference being had to the accompany- Q ing drawings, forming a part hereof.
le The presentinventiorns directed `to iinprovcments in brake-bandsthough not nec`` a essarily restrictedthereto, as the same prin-` ciplc may be applied to friction clutches asy will hereinafter more lfully appear. The object sought is toprovide a brake-band for the brake drums of transmission shafts and the like which will have a cushioning edect as the band alternately gri s and releases its .hold on the drum, this e ect being brought about by a resilient member or spring inter'- posed between two sections of the band as will herein more fully appear. The presence of the spring eliminates all shocks when the brake is applied, said spring adjusting itself to the weightof the mass whose rotation is to be arrested, and when applied to the drum' of the transmission shaft of a motor vehicle the occupants of the vehicle are subjected tono jars whatsoever. The advan- 30 tages of the invention will be apparent from the followin detailed description in connection with vt e 'accompanying drawing in which Figure l represents a cross-section of a drum of the transmission gear of an ordinary automobile or self-propelled vehicle .showing our invention applied thereto; Fig. 2 is a side View of one-half of the brake band showing our improvement; Fig. 3 is 40 a face view of the brake-band, parts being 4broken away; Fig. 4 is a side elevation of the @am4 hubl of the pedal lever carried at one end 0f the' edal shaft; and Fig. 5 is an end view of t e hub.
Referring to, the drawings, D represents the drum on the transmission shaft S of an ordinary automobile, the same beingmnuntn ed in the casing or transmission housing C as well understood in the art, the parts referred to being shown herein more or less conventionally. Encompassin the drum is -the open bra e band 1 provi ed with the usual liner a' of fabric, leather or other suitable material, said band having riveted 5 5 thereto at a point'substantially opposite the gap in the band, one end of a supplemental y speiacation of Letters-raten.' 'patented July 22, 19195 application-andinas14,1918. seriainogaaaosa. 'l
or complementary band or strip 2 to the free end of which is secured one of the shoese," the opposite shoe e being secured to the op-` posite end of the band '1. Riveted to the 60L strip 2 at a point about midwa of its lengthy is one end of a sinuous spring hand or plate`,l or equivalent resilient member 3, the opposite endbeing, loose and the spring being free toyie'ld betweenv the bands 1 and-'2. 65 The free end of the member 3 terminates' at a point near the free end of the Jband, Y The shoes e, e, as well known in the art, are y forked, the forks loosely embracing Vthe pedal shaft e one end of which terminates in a nut @engaging the outer face of the' :fork of the shoe secured to the band 1, the l oiposite' end of the shaft passing loosellV t rough the bearing 5 of the casing. against which the opposite fork 'or that it? terminating the shoe secured to the bandi# bears as an abutment. The shaft 4c beyoni the bearin '5 carries the canali-ub from which lea s the usualpedal lever 7 termiIk hating in the pedal 8. -An expansion spring 8T 9 coiled about' the shaft 4 is interposedbe" tween the shoes e, e, thus insuring 'the 7ermanent engagement oithe forked-eindj of one of the shoes against the bearing'.. 'As Q well understood in the art .the outer-end of' the bearing 5 is provided with cam 'formations o which are engaged by corres onding cam formations c on the inner en of the hub 6. When the driver ap lies his foot to the pedal 8 so as to rock the ub -6 in'proper 9o direction to cause the cam formations c to ride up`on the cam formations c of the bearing 5, the result is that the shaft a is pulled outward vthereby drawing the shoes e eftogether, and contracting the band. .this of course'brakes the drum. In the present improvement however the draft is exerted on the opposite free ends of the bands 1 and 2 respectively, so that the. latter (band 2 vmust act on the drum through the 100 interme iate spring or cushioning member 3. The drum 1s thus gripped by the draw* ing together of the-free end of the sup lemental band 2 andthe opposite free endp of the band-1, the spring 3 'between the bands inf acting as' a cushion or moderator to Areduce the jar and insure -a uniformly progressive application of the brakes. The grip on the drum is thus softened andthe absencejo shocks and tremors Iis marked ,when a plied il@ to the transmission gear of the or mary automobile.
cla-im is:
1. A brake-band comprising a main band having lts endsfree, a supplemental band se- .cured at one end to the main band and disposed adjacent thereto, the opposite end of the supplemental band being free and cooperating With the opposite' free end of the main band, and a cushioning member havn one end fixed to one of the bands at al point between the fixed end of the supplemental band and the free ends of the bands,
-said member being confined between the Supplemental band and the main band.
2. A brake-band comprising a main band having its ends free, a supplemental band secured at one end to the main band and disposed adjacent theretov` and extending over a substantial portion of the length ot' the main band, the opposite end of the si|pplernental band coperating with the 'opposite end of the main band, a sinuous spring strip having one end secured to the supplemental band, and interposed between the supplemental and main bands, the opposite end of the strip being free.
A brake-band comprisino a main band having its ends free, a supplemental band secured at one end on the outside of the main band at a point substantially opposite the gap in the band and extending to a point adjacent one end of the main band, a sinn ons spring strip' or plate interposed between the main and supplemental bands, one end of the spring being secured to the supplemental band at a point removed from the free end of the band, the spring being free to yield between the bands and havingits opposite end free and terniinating at a oint near the free end of the supplemental and.
In testimony whereof we alix our signaturesthis 11th day of June,'1918.
