ANTISQUEAK CUSHION FOR AUTOMOTIVE BRAKES.
Application filed February 11, 1925. Serial No. 8,895.
This invention relates, generally, to improvements in brakes for automotive vehicles and the like; and the invention has reference, more particularly, to a means in combination with the brake-bands and their linings adapted to provide against squeaking, squealing and chattering when the brake-bands aretightened on the brake drums.
The invention has for its principalobject to provide a resilient cushion intermediate the ends of the brake-lining and the brakeband, whereby the shock and stress of initially applied pressure in operating the brakes is absorbed and compensated, so that operative pressure of the brake-band is more evenly distributed around the brake-drum, and tendencies of the brake-lining to chatter and squeak, by reason of unequal distribu-.
tion of friction, is eliminated.
The invention has for a further object'to provide a novel means for applying the resilient cushions in proper assembled relation to brake-bands and their linings, both in connection with new and old brake assemblies.
Other objects of this invention, not at this time more particularly enumerated, will be clearly understood from the following detailed description of the same.
The invention is clearly illustrated in the accompanying drawings, in which:
Fig. 1 is a plan view of a resilient cushion member, made according to and embodying the principles of this invention, the same being detached from 0 erative relation to a brake-band and its lining; Fig. 2 is a. similar plan View with the novel applying tool or clip attached thereto, and by aid of which the cushion may be operatively assembled with a brake-band and its lining; Fig. 3 is .a longitudinal section taken on line 3-3 in Fig. 2; Fig. 4 is a transverse section taken on line 4-4 in Fig. 2; Fig. 5 is a side elevation of a brake-drum and brake-band with its lining, the same illustrating the novel resilient cushion members operatively assembled in connection with said brake-band and lining; and Fig. 6 is a fragmentary transverse section, taken on line 6-6 in- Fig. 5.
Similar characters of reference are employed in all of the hereinabove described views, to indicate corres onding parts.
Referring now to sai drawings, the reference character 1 indicates the novel resilient cushion member. The said cushion member 1 consists of a preferably rectangular body, which may be of a thickness preferably not exceeding one-eighth of an inch,
and of a length somewhat exceeding thewidth of the brake-band and lining with which the same is to be assembled. The said cushion'l is preferably made of rubber, but
troduced between the brake-band 6 and lining 7 adjacent to each end of said brakeband. Ordinarily, when the brake-band 6 is actuated to contract the same around the circumference of the brake-drum 8, andthus cause the lining 7 to frictionally bind upon or grip the brake-drum surface, the outer end portions of the brake-lining 7 will be immediately thrust or jammed against the brake-drum surface, and as a result, before the frictional grip of the lining is equally distributed along the brake-drum surface,
there is a tendency of thebrake-band lining to squeak, squeal or chatter. When, however, my novel cushion members are inserted between the end ortions of the brake-band and its lining, an the brake band is actuated or contracted, the first thrust of the endportions of the lining against. the brakedruni surface is partially absorbed by the cushions 1. so that said end-portions will yield radially outward relative to the brakedrum, until the contraction of the brakeband draws the lining firmly and evenly down upon the brake-drum surface, thus uniformly distributing the frictional pressure, and therefore eliminating all tendency to speak, squeal or chatter.
In order to make easy and convenient the process of assembling the cushions 1 in operative relation to the brake-band 6 and its lining 7, and especially when applying said cushions to old equipment, I provide adjacent to one end of each cushion 1 a transverse rowof perforations or eyes'3, and I same on through.
also provide a novel attaching tool or clip 2 which is designed to cooperate with the perforate end of the cushion 1, so as to be coupled therewith. Said attaching tool or clip 2 comprises a main body, preferably made of sheet metal, which is doubled upon itself as shown more particularly in Fig. 3. One free transverse end of said clip body 2 is provided with a plurality of upturned teeth 4, corresponding in number'and spacing to the number and spacing of the perforations or eyes 3 provided in the end of the cushion 1. The other free transverse end of said clip body 2 is disposed to fornf a cover portion 5 adapted to engage and close over the free ends of said teeth 4. It is preferable to taper the width of said clip body 2 from its toothed end toward its doubled end, as shown in Fig. 2.
The said attaching tool or clip 2 is operatively coupled with a cushion member 1 by spreading apart the free end portions of the former to receive the perforate end of the latter, so that the teetha may be entered through the perforations or eyes 3, as shown in Figs. 2, 3 and 4. Vhen the attaching tool or clip 2 is thus coupled with a cushion member 1, the doubled or outer end of the tool or clip is inserted, at the desired location, between the brake-band 6 and its lining 7. This operation may be aided by first inserting a screw driver or other sharp tool between the brake-band and its lining, to thus produce an initial separating opening into which the end of the tool or clip may be inserted. The tool or clip having been inserted between the brake-band and its lining, the same is thrust laterally from one side of the brake-band to the other, until its free end projects beyond the opposite side from that at which it was entered, whereupon the operator grasps the outwardlv projecting end of the tool or clip and pulls the The cushion member 1 thereupon follows or is pulled after the tool until it is properly seated intermediate the brake-band and its lining. Since the cover portion 5 closes over or covers the teeth 4, the latter can not catch or otherwise obstruct the movement or passage of the tool or clip between the brake-band and its lining. As before stated the cushion member 1 is made somewhat longer than the width of the.
brake-band and its lining, and consequently its perforate end, when the cushion is roperly positioned, will project outwardly beyond the side of the brake-band and its lining, and, therefore, the tool or clip 2 may be readily detached from the cushion, by separating the free end portions and then Leagues withdrawing the teeth 4 from the perforations or eyes 3 of the cushion.
Having thus described 'my invention, I claim:
1. A resilient cushion for the purposes described having initially attached thereto a removable metallic clip, said clip being disposed in endwise extension from one end of said cushion.
2. A cushion for the pur oses described, said cushion comprising a re atively thin resilient body of rectangular shape, said body having a transverse row of perforations adjacent to one end thereof to receive the attachment therewith of a metallic clip for endwise extension therefrom.
3. A cushion for the purposes described, said cushion comprising a relatively thin resilient body of rectangular shape, said body having a transverse row of perforations adjacent to one end thereof, and a detachable metallic clip,. said clip comprising a clip body doubled upon itself, one free transverse end of said clip body having a plurality of upstanding teeth to pass through said perforations of said cushion, and the other free transverse end of said clip body providing a cover portion to close over the free extremities of said teeth. 4. The combination with a brake-band and its lining of a resilientcushion member ositioned between the brake-band and its ining adjacent to a movable end of said brake-band, said cushion member having initially attached to one end thereof a removable metallic clip for threading and drawin said cushion member into place interinedlate said brake-band and its lining.
5. The. combination with a brake-band and its lining of a resilient cushion member positioned between the brake-band and its lining adjacent to a movable end of said brake-band, said cushion member having a transverse row of perforations adjacent to one end thereof, and a detachable metallic clip for threading and drawing said cushion member into place. intermediate said brake-band and its lining, said clip co1nprising a body doubled upon itself, one free end of said body having a plurality of upstanding teeth to pass through said perforations of said cushion member, and the other free transverse end of said-body providing a cover portion to close over the free extremities of said teeth.
In testimony that I claim the invention set forth above I have hereunto set my hand this third day of January, 1925.
CHARLES E. CHRISTENSON.
