The objects and advantages of my inven tion will be readily comprehended from the 15; detailed description of the drawings, where- Figure 1 is a side elevation of my improved means and portion ofa truck frame provided w1th apocketformed to receive the link and keeper elements.

Figure 2 is a cross sectional View taken on the line 22 ofFigure 1 looking downwardly. Figure 3 is. a perspective View of one of a pair of complementary keeper elements, as

,employed in Figure 1.

Figure 4 isa top plan view illustrating a modified form of keeper elements adapted more especially for use with the U-shape type of hanger.

Figure 6 is a vertical sectional view taken on the line 66 of Figure looking in the direction of the arrows.

Figure 7 is a cross sectional view taken on the line 7-7 of Figure 6 looking downwardly. I, p

Figure 8 1s a perspective vlew of one of the keeoer elements employed'with the construc-' tiori shown in Figure 5. Figure 9 is a perspective view of a portion of truck frame provided with-my improved integral pocket.

The exemplification of closed in the first three figures of the drawings is especially intended for use inconnection with the continuous or closed link type of hanger, a portion whereof is shown at The truck frame 16, at a point adjacent to the so wheels of the truck, lie-preferably provided Figure 5 is an elevation of the construction shown in Figure fl:-

theinv'ention as dis- I 1928. Serial No. 291,925.

with a projection or arm 17 the outer end whereof and on one face, namelythe face disposed toward the wheels of the truck, is pro vided with the vertically spaced portions 18, 18 arranged to provide a socket or pocket therebetween.

The portions 18, 18 are. preferably arranged at an upward inclination toward theouter ends. so that the socket or pocket will decline toward the inner closed end'thereof, Where the two portions 18, 18 are reenforcedand'pr vided with the ribs 19 formed integral'with the opposite sides of the portions.18, 18';'the ribs or integral portions being provided at the forward side with an arcuateface-zas very clearly shown in Figure 9. By reason of the formation of the arm with the ribs 19, 19, the pocket between the portions 18, 18, at the inner end, is provided with'the socket por tion 20. The lips or. projections 18', 18, ad-

' jacent to their outer ends, are provided-with the registering bolt-receiving openings 21, 21; and the upper projection 18 is shown re enforced by the vertically, disposed vrib 22 extending lengthwise offthe arm '17 and preferably taperingtoward'the outer end of the arm, as shownin Figure 9.

Where the continuous type of link hanger 15-is to be employed, keeper elements 23, one of which is shown in Figure 3, are preferably employed. Tlie'pocket, intermediate of the projections or portions 18, 18 of .the arm, are adapted to receive a pair of these keeper elements 23, which are identical in construction, with the matchingor abuttingfaces'provided with the longitudinally disposed groove 24 adaptedto' receive the upper end of the link 15'. The longitudinal sides of the keeper elements 23, which are to be locatedwithin the pocket, are each provided" with the angula'rlyformed shoulder 25 terminating shortof-the ends of the keeper elements, so asto fit withintlie: socket at the innerend: of v the, pocket between theiribs 19,- 19.

The ends of the keeper elements, adjacent, to the shoulder 25, are preferably formed arcuate as shown at 26, 26 so as to seat against the arcuate faces ofthe vertical ribs19, 19.

that with. t

t is apparent from the structuregshown e. projection or shoulder on the top and bottom keeper elements 23 seated within the socket rearward of the forward faces of the ribs 19, that longitudinal movement of the keeper elements'23 is impossible and that a proper positioning of these elements is ensured.

The projections or extensions 18, 18 of the 3 arm 17 of the truck frame, in addition to having the outwardly upward slope as previously stated, are preferably formed to slightly diverge toward the outer ends, thereby providing a pocketof slightly greater vertical dimensions at the outer end than at the inner end thereof. The keeper elements changeable and permitting either keeper ele- V ment to be located either above or below the a hanger, with the result that easy assembly is made possible and low cost of manufacture provided.

The forward longitudinal sides of the keeper elements 23 are each shown provided with an arcuate-groove 28 disposed vertically .across the front sides to receive or permit passage of a bolt 29 which is inserted through the registering holes 21 of the projections or extensions 18 of the arm; the bolt passing through'the grooves 28, causing the keeper elements 23 to be held in the pocket.

By reason of this construction and arrangement, it is apparent that practically no I strains are placed on the bolt 29 and that accidental displacement of the keeper elements is less likely. I 7

In order to prevent the accidental loss of the retaining bolt 29 (a remote possibility with the construction shown), I prefer to provide the bolt locking means'30, the construction whereof is more clearly disclosed in Figure 6. This locking means consists of a bendable thin sheet metal plate having an aperture at one end for passage of the bolt 29, while the plate, after passage of the bolt 29 therethrough, is then bent'upwardly and rearwardlyover the head of the .bolt, as

is shown, thus preventingv accidental displacenut on the lower end of the bolt.

pe'rrnit the application of the bolt locking ment of the'bolt'29 in the event of loss of the In order to means, the upper flat face of the keeper element 23 is provided witha depression 31, see

Figure 3, of a depth commensurate with the thickness of the keeper plate 30 so as to pergitudinal movement, as well as proper bearing for the ends of the pin provided.

The pocket in the arm 17 of the truck frame may be identical in construction to that previously described, being formed adj acent to the inner vertical rib 19 with a groove'or socket 36 to provide clearance for the enlarged eyeletted end 35 of the U-shape hanger 32 and thus permit free oscillation of the latter during the operation of the brake mechanism. 7 i

The keeper elements 34 have their'main or intermediate portions formed substantially similar to the keeper elements 23 as is apparent from a comparison of Figures 3 and 8, with their matching faces each provided with the longitudinal groove 24 and their inner longitudinal sides provided with the shoulder 25 adapted to fit into the socket 20. at the inner end of the pocket between ribs 19. The keeper elements 34 at each end are provided with an extension 37 shown formed integral with what may be termed the outer longitudinal side of the keeper elements; said extension curving or extending toward the rear longitudinal side of the keeper element and in spaced relation with the main portion thereof to provide the sockets or slots 38 for. reception of the upper. eyeletted ends 35 of the U-shapehanger 32and permit free oscillatory movement of the hanger 32.

The ends of the extensions 37 are enlarged as at 39 and provided on their'lower or matching faces with grooves 40 aligned with the groove 24: to receive the ends of the hanger supporting pin 33; the outer faces of the enlargements of extension 37 being preferably provided with the'walls 41 which close the outer ends of the grooves 40 and thus prevent longitudinal movement of the pin 33 in the composite groove 2 1-40.

The keepers 34 (of which a pair are emwedging fit into the gradually and slightly flared pocket between the extensions 18 of the arm 17 of the truck frame; 7

The keeper elements 34;, as shown in th drawings, are preferably of slightly greater transversewidththan the keeper elements @23, for thepurpose of ample strength and mu: "the keeper elements 23 to be properly are therefore provided with the bolt-receiv restate ing apertures 42 instead of the grooves 28 as in Figure 3, so that the retaining bolt 29 will not only pass throu h the apertures 21 of the extensions 18 of the arm, but will also pass through the holes 42 in the two superposed keeper elements 34.

The keeper elements 34, like keeper elements 23, have been shown on their upper fiat faces with a similar depression 31 for the purpose of receiving the bolt-locking element 30 previously described.

In practice, where a continuous link 15 is employed, the upper end of the link is inserted into the groove 24 of the lower keeper element 23; the upper keeper element 23 is then put into position with its grooved face downwardly so that the matching grooves 24 of the two keeper elements or blocks will constitute a suitable channel whereby free oscillatory movement of the hanger or link 15 will be permitted.

lV here the U-shape hanger 32 is employed, the supporting pin 33 is passed through the upper eyeletted ends 35 of the hanger 32 and the intermediate part of the pin placed in the intermediate groove 24 of the lower keeper element, with the ends of the pin, namely the ends beyond the eyeletted ends 35 of the hanger, resting in the aligned grooves 40 of the extensions 37 of tne keeper element 34. The upper keeper element 34 is then put into position with its grooved face downwardly so that its grooves 24-40 may register with the grooves of the lower keeper element and thus completely enclose or house the hanger supporting pin 33.

The assembled elements (either of the construction shown in Figure 1 or of the type shown in Figure 4) are then inserted into the flaring and upwardly outwardly sloping pocket formed between the extensions 18, with the shoulders 25 disposed into the pocket at the inner end intermediate of the ver tical ribs 19.

These shoulders not only tend to center the keeper elements in proper position, but will also prevent any lateral or sidewise movement of the elements. With the keeper elements and hanger or supporting pin and hanger in place as previously described, the

locking bolt 29 is then inserted into place thereby maintaining the keeper elements in their wedged position in the pockets.

It is apparent from the constructions de scribed that either type of keeper elements may constitute an upper or a lower element as they are identical in construction and therefore interchangeable; and it is also apparent that substitution of either type of hanger link may be made.

It is also evident thatno great strains are applied to the retaining bolt 29 and that accidental removal of the bolt, where the retaining means 30 is not employed, is also less likely because of the general constructioii aI id arrangement, even though the niits entire bolts'29 slio'uld'be lost; while-chatter or'vibration betweenthe elements and the truck frame is prevented and the possibility {if wearitlms inaterially' reduced; while at the" same time a considerable saving in ma terial and expense is possible because of this general construction and-arrangement.

While I believe the constrtictions shown "described to 'be' 'the best, embodiments or invention, certain modifications ma be made without, however, departing from the spiritof my-invention.
