Speccaton of Letters Patent.
Patented Sept. ft2, i946.
' Application filed .Tune 14, 1915. Serial 1\T o. 34,079.
To all fr0/wm t may concern:
Be it known that I,-JorIN F. REYNOLDS, a citizen of the United States, resident of Cleveland, county of Cuyahoga, and State of Ohio, have invented a new and useful Improvement in Brake-Shoes, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying kthat principle, so as to distinguish it from other inventions.
My invention relates to brake-shoes, its object being to provide a brake-shoe construction which will be economical of manu facture and efficient in its operation.
Said invention consists of means hereinafter fully described and particularly set forth in the claims.
The annexed drawing and the following description set forth in detail certain means embodying my invention, the disclosed means, however, constituting but one of various mechanical forms in which the principle of the invention may be applied.
In said annexed drawing F igure 1 represents a rear elevation of a brake-shoe construction embodying` my invention, together with a portion of a-brake-rod upon which said shoe is mounted. Fig. 2 representq a side elevation of. said shoe. Fig. 3 represents a sectionof a shoe and connected parts, said section being taken upon the plane indicated by line III-III in Fig. 2. Fig. 4 represents a section taken upon a plane indicated by a line IV-IV in Fig. l. Fig. 5 represents a rear elevation of one of the springsconstituting part ofthe construction, and Fig. 6 represents a side elevation of such spring. Fig. 7 represents a plan of the intermediate member forming-part of' the invention and Fig. 8 a sidev elevation of same.
rEhe illustrated embodiment of my invention comprises a suitable supporting brakerod l whichextends, in the usual manner, in a direction parallel with the axis of the wheels of the vehicle and is movable toward and from same. The outer ends of this rod form journals upon which the shoes 2 are mounted. Each shoe consists of an iron casting, upon the inner face of which the friction member 3 is removably bolted in any desired manner. The shoe is furthermore formed with a central projecting portion 4 formed with an elongated slot 5.
This projecting portion is furthermore formed with two hollow bosses 6, 6, which form bearings for the end of the rod, as shown lin Fig. 8. Mounted intermediately of these bosses and having a width substantially equal to the distance between same, is a separate member 7, Figs. 7 and 8. This member is provided with a cylindrical seat 8 through which the rod l passes, as shown in Fig. 3, to which rod itis fixedly secured as hereinafter described. Member 7 is furthermore slotted as at 9, said slot being slightly enlarged as at 10,` the interior faces being recessed as at 11, l1, see also Figs. 3 and 4.
Surrounding the inner end of each boss 6 is a coil-spring l2, Figs. 5 and (S. rIhe one end 13 of each such spring engagesythc inner surface of the shoe 2, as shown in Figs. 2 and 4, and the other end 14 of same is bent so vas to lie within one of the recesses 1l of the intermediate member 7, the bent portions having accessto the recesses 11 through the enlargement 10 of the slot. This latter end of the spring is held in place againstl displacement by means of a vbolt 15 passing through suitable circular openings 1G formed in the slotted portion, as shown in Figs. 3 and 4. rFhis slotted portion of said member projects through the elongated opening 5 formed in the shoe, as shown in Fig. 4, and the slot intersects the cylindrical seat 8, so that by screwing up the nut on the bolt, the member 7 may be clamped upon the rod 1, thereby securing the entire brake-shoe in place thereon, as will be readily understood. The end 14 of each spring is in contact with that inner surface of the member 7 which lies nearest that surface of the shoe 2 which the other end 13 of such spring engages, as shown in Fig. 4. 'Ihese springs are of equal size and are of a diameter such that in order to assume the position given them as shown in Fig. 4, it is necessary to contract the diameter of the spring so that the ends 13 and 14, when in position in the structure, are a greater distance from each other than they would normally assume when the spring is in a condition of rest. The end 14 of each spring, therefore, exerts a pressure against the intermediate member which tends to oscillate it, but the two springs being of equal diameter and strength, these tendencies counteract one another and the shoe normally assumes, therefore, a position of rest u'pion ythe rod l. .Any displacement of the shoe vfrom this position, hence, is resisted by one orthe yother of the two springs.
".By means of the 'above-described con- .struction it will in consequence be seen that y the'art, the angular relation of the shoe changes inf accordance with the position of the` body of the vehicle with reference to theaxle and therefore with reference to the wheel-tire, so that various angles are formed between .the brake-slice and the wheel-tire prior to engagement, depending upon the depression 4or elevation of the vehicles body, the; .brake rod being mounted upon this body.: By reason of this arrangement, there- -ore,'i.t.will be seen that the friction member may `always be caused to engage the wheeltire. throughout .the full length of such member, so' that the shoe may always be caused to. operate with a maximum of efficiency.
Iny order to prevent asy far as possible dirt and .other extraneous matter from entering the interiori of. the brake-slice through the .opening 5 and through the space formed be- -tween the shoe and the intermediate membei-'7, the latter is provided upon its upper .surface and at the sides thereof, with two integral upwardly extending walls 17, Figs. .4, tand 8. These walls substantially ill `the openspace between .these members and .thus prevent the entrance of such dirt or Aother matter. The lower portion of the saidv member 7 need not be provided with these protecting walls for the reason that this part of the opening being upon bottom is normally protected from such entrance of dirt and the like by gravity.
Having fully described my invention, what I claim and desire to secure by Letters Patent is 1. In a brake-shoe, the combination of' a Asuitably supported and movable brake-rod;
suitably supported and movable brakeaod,
a slice provided with two hollow bosses each formed with a bearing for the reception of journals carried by said rod; an additional member ixedly mounted upon said rod and intermcdiately of said bosses, having a slotted lug extending outwardly through an elongated opening in said shoe and including a bolt passing through said lug; and two springs surrounding said bosses respectively, each having one end in engagement with said shoe and the other endinounted upon said bolt.
Signed by me, this 10th day of June, 1915.
