' 18 Claims. (oi.15s 24.)

roller pivots or trunnions, and particularly the pivot to which oneend of the operating spring of the roller is anchored, for the'purpose of pre-.

venting wabbly action of the roller and to pre vent rattling or other undesirable noises ordinarily produced by relative movementbetween the trunnions and their supporting brackets as a result of vibrations occurring in. the bodies of the vehicles; l i

The present invention is particularly adaptable'for use with rollers havingtrunnions of the type shown and described in the applicants copending applications, Serial No. 636,071, and Serial No. 636,072, filed respectively on October 3, 1932, each of which, and the present application, are continuations in part of the applicantsprior 25 application, Serial No. 580,706, filed December In the accompanying drawing:

Fig.- 1 is a perspec'tiveview of abracket in accordance with the principlesof the pres- 3 ent invention; l

Fig. 2 isa sectional elevation taken on" the line 2--2,'Fig. 1; 3

Fig. '3 is a view'similar to Fig. 2, butshowing a roller'trunnion in positionin the bracketifand Fig.4 is a sectional-plan view taken on'the The bracket forming the subject of the p resent application is composed of two sheet metal stampings, land 2 respectively,which are rig- 4O idly secured together in a manner to prevent relathereof. The base 10 is'provid'ed'with apairor made flange 16 disposed in substantially the same plane as the flat neck portion 140i the bracket.

7 The outer edge 1'7 of the flange 16 is bent inwardly to a plane substantially paralleling that of the said flange, thereby providing a groove 18 that is adapted to receive a substantially flat head plate 20 which forms the major portion of. the stamping 2. Thj"0lll71 edge of the head plate 20' is seated in the groove 18 andis rigidly secured-"therein by the inturned edge 17 of the I flange 16 when the said edge 17 is bent around the said outer edge of the plate, 20 and pressed inwardly overtheplate toward thebase of the flange. g m

. Extending from one side and in the plane of the head plate 20,;along and adjacent the neck 14 and conforming. to the general shapethereof,

is an ear 21. The opposite edges of the ear 21 are seated in grooves 18a, 18a respectively which are formed along the opposite sides of the neck 14 7 5 by turning the outer edgesl7a, 17a on said neck over the corresponding edges ofthe ear 21, the grooves 18a, 18aLof the neck l l'forming continuationsofathefgroove 18that extends around the hollowhead 1.5,:the inturned edges 17a, 17a

of the neck '14 constituting continuations of the head. s

"Theilstamping 2,. particularly, is composed of relatively stiii sheet metal, such as iron, steel,

brass, etc. having a substantial degree of inherent resiliencygor capable. of being temperedor otherwise hardened to provide such resiliency as may. be .required for. purposes hereinafter set forth. 1 I q The headplateZO is provided with an opening 25 whichis adapted to receive one'of the trunnionszc ofa spring-loaded roller Xyas illustrated in FigsBand l. i

In the present instance, the trunnion :c is'rotatably mounted in one end of the roller X. and

is provided with a prcjectingend that isof'rectangular cross section: The particular trunnion illustrated in the present case is the one't'o which one end of the operating spring of the roller is anchored, the "oppositeiendotthe spring being anchored to the; barrel of the, roller, thetrun nion, therefore, is" arranged to be nonrotatably supported by thebracket to provide for. rotation of the roller in one direction by the spring con- 1 fined within the roller, ,theroller revolving on and 1 about the fixed trunnion. i In order to accommodate the rectangular cross sectionof the trunnion rand to 'prevent;,rota-;

tion of the trunnion relative to,.the bracket, the 9 i opening in the head plate 20 is correspondingly of rectangular form, the length and the width of the said opening 25 being such as to snugly fit the rectangular end of the trunnion x.

In order to prevent relative lateral movement between the trunnion :c and the bracket and to provide a firm bearing for and longitudinallyof the trunnion one or more of the; sides of the opening 25 is provided with a springtongue 26. In the present instance a pair of such tongues are respectively disposed at opposite ends of the open-. ing 25, in opposed relation to each other, and extend substantially at right angles to and from the plane of the head plate 20., said tongues prmjecting into the dish-like head 15, of the bracket and firmly clamping the trunnions therebetween. The

tongues

26, 26 afford such sturdy support for the trunnion that the trunnion is held rigidly in a position perpendicular to the head plate, permitting free rotation of the roller without permitting any wabbly action thereof.

For the purpose of the present invention the planes of the

tongues

26, 26 are slightly convergent, in order that the said tongues will press firmly against opposite sides of the trunnion a:

when the said trunnion is inserted within the opening 25 ofthe bracket, as illustrated in Fig. 3, whereby the tongues '26, 26 are spread from their convergent relation shown in Fig. 2 to the substantially parallel relation shown in Fig. 3. Such construction and cooperation of parts eliminates any play or relative movement between the trunnion and the bracket, such as may result from slight variations between the cross sectional dimensions of the trunnion and the'opening within the limits prescribed by the manufacturers" tolerances, thusv any rattling or other undesirable noises resulting therefrom will be eliminated.

In the present instance, the

spring tongues

26, 26 are formed as integral parts of the head plate 20 and the resiliency of the sheet metal of which the stamping 2' is formed provides the necessary resiliency in the

tongues

26, 26 to;permit thesaid tongues to yield as the trunnion is inserted therebetween and at the same time cause the tongues to. grip the trunnion firmly at oppositely disposed points, to prevent relative movement between the trunnion and the bracket and to support the trunnion in rigid perpendicular relation to the head plate of the bracket to avoid any wabbling or looseness as the roller is rotated about. the pivot or trunnion.

The

tongues

26, 26 and the opening 25 may be readily produced by forming an H shaped slit in the head plate and bending the two portions lying between the side slits at opposite sides of the cross. slit outwardly in opposite directions along lines parallel to the cross slit andconnecting the opposite ends of the parallel side slits.

As shown in Figs. 3 and 4, the hollow dish-like head 15. serves as a means for completely hiding the end of the trunnion and the spring tongues from view.
