Application November 22, 1932 Serial No. 643,910
"1 Claim. (01. 74-110) This invention relates", to .improvements'in braking devices and has particular reference to means for increasing brake leverage.
The principal objectof the invention is to produce a device which may be attached to the ordinary brake system of a motor vehicle or any other device wherein there is a pulling action. A further object is to produce a device which is economical to, manufacture and simpleto install.
A further ob ect is to produce a device wherein the slack within the brake rods may be easily.
. taken up in the device.
Astill furtherobject is to produce a device. wherein there may be a quick application of the brakes during the initial movement of the brake pedal and later an increased leverage effect during the latter part of the brake movement.
Other objects and advantages will be apparent during the'course of the following description;
In the accompanyingdrawing forming a part of this specification and in which like numerals are employed to designate like parts throughout a the same,
the manner in which the same might be attached to an ordinary brake mechanism,
Fig. 2 is a view similar toFig. 1, showing the parts in braking position, and
' Fig.3 is a modified form of our device.
In the accompanying drawing wherein for the purpose of illustration is shown a preferred em bodiment of our invention, the numeral 5 designates a cross rod ofa braking system, or may be the pivotal connection of a brake arm" 6. To this arm 6 is usually connected *a brake rod 7 andis pivoted asat 8.- My invention consists in inserting" between the rod 7 and the arm 6 a casting 9 which is held to the lever 6 by the pivot pin 8. This casting has arms 11 and12 through which" set screws. 13 and 14, respectivelypass and engage the lever 6. Within the casting 9 is formed a slot 16 in which is positioned a roller '17, which roller is carriedlin 'aclevis 18secured to the pull rod 19, which pull rod is in turn connected to the brake pedal not shown- The operation .of our device isas follows:-
Assuming that the samejhas been applied to Fig.=1 is a side elevationof our device showing a braking system as shown in Fig. 1, the parts will be in the positions shown, and it will be noted that the pivotal point of. the roller is a distance A fromthe cross rod5 and this distance I A is less than'the distance from the cross rod a to the pivot 8. It will, therefore be apparent that when the pull rod 19 is moved toward the right of the drawing, the amount of movement will be increased to the brake rods 7. As soon asv the slack has been taken up in the brakes the parts will have moved from the position of Fig. 1 to the position of Fig. 2 and the roller 1'7 willhave moved from: the top ".of the slot 16 to the bottom'of the slot 16' and therefore the distance Aof Fig. 2 is greatly 'increasedfrom that of Fig. 1. greater leverage is exerted on'the cross rod 5,
arm 6 and brake rod 7, thus making it easier to apply the brakes as they are undertension.
Inthe form shown in Fig. 3, the construction accomplishes the same purpose and it will, be 7 noted-that the pullrod 19, yoke 18 and roller 17 are the same as shown'in Figs; land 2, and that l the roller 17 travels in the slot 16 in a connector 22, which is secured to the .rod 5 at any point i Within its length. Of course, the rod 5 need not 3 necessarily be a portion of a braking system, the essential'feature of our device being that we can increasethe leverage as the movement of the pull rodincreases.
It is to be understood that the form of our invention herewith shown and, described is to be L 1 taken as a'preferred example of the same and a secured to said lever, a brake rod pivotally se-v curedto said lever, adjustingvmeans for positioning said'casting on said lever with respect to its pivotal connection, said casting having a slot formed therein and. a movable element carried in said slot and'capable of being connected to apull rod. 1 v
