- provements in Spring Suspensions, of which the following is a specification.

Our invention relates'to spring suspensions of the type disclosed in application for United States Letters Patent, Serial No; 383,189, wherein the spring and the vehicle body or other related parts are connected by flexible 1inks Which are rigidly secured at their opposite ends and which are so constituted *as to permit perfect freedom of spring action While controlling-side sway and other objectioneble movements.

The objects of our invention are to provide simple 21nd practical means for enabling the attachment anduse of suspension means of this character with vehicles new on the market and ineveiqy day use. i

In the accomplishment of these objects We have devised various forms of attachment devices capable of ready application to the forms oi vehicle springs used with different makes or" cars.

In the accompanying drawings we have illustrated 21 number of difi'erent forms the invention may take, but wish it understood that further modifications may be made without departure from the true spirit and scope of the invention as hereinafter defined and claimed.

1n all the forms of the invention iilus-r treted the flexible connecting link, which is designated 25 and. which is made up of one or more layers of suitable flexible nieterial such rubber impregnated belting of the like, is .lly secure held at its opposite ends betvieen i cooperatingoi 17) else theclemps which app '3 to-one spring member alike in the v consist in. each stance of a channel sped bracket 26 sdspted to overlie the of the main lest of the spring and on ungeai with side walls ere bracing the edges of tee spring and perfo rated in line with the eye 28 which is ordi. narlly turned in the end of the main leaf to receive it fastening belt 29" The side Walls'of these :chonnei bracket are also shown as per-fore d at points inward "from the ends of the'springs to re eive e supple mental fastening belt which extends across the face of the main lest so to secure the bracket egeii nivotei movement about the main fastening holt The clamp carried by ti cnonnei bracket consists oi. cooperating relatively fixed and movable jaws 31 and 32 secured together by bolts, rivets or other fastenings These clamp jaws have relatively Wide clamping faces so as to securely grip the songs links over extended areas and hence to iii iilv secure the same without liability of teerinlg' or abrasion.

The attachment device for the other end of the link like 'ise is made up of coopen sting relatively fixed-end movable clamping jaws 34:..35 secured firmly together over the other festeniogs 36.

. Ford car. The bracket 26 being of a size to fit the forward front spring it will be evident that this makes it possible to substitute this improved Form of link suspension in place 01 the usual Ford rigid link suspension by simply attaching brackets 26 to the ends of the front spring and replacing the usual shackle posts with our special clamp supporting posts 3?. In making this change the bolt 29 may be the same bolt which was formerly used for the connection of the rigid suspension links at the ends of the front spring and the auxiliary securing bolts-- may be taken from the clips ordinarily used on the spring and which become unnecessary when the channel brackets 26 are applied. since these brackets may overstand the second leaf. as We have indicated, and hence operate in the capacity of spring clips.

The form of rear spring connection shown in Figs. 3 and 4c is generally similar to the front spring connection, thcmain difference being that the clamp carrying post 38 is provided with a horizontal boltextension 39 instead of the Yertical bolt extension shown, to lit a corresponding horizontal seat on the rear axle housing.

in Figs. 5 and. 6 'WGllfiVQ illustrated a connection for the rear end of a semielliptic rear spring. The spring attached bracket and clamp construction is generally similar to that first described and the only practical diii'erence is that in this casethe attachment bracket for the opposite end ofthe link is provided with cars a l pierced to receive the shackle bolt 4-2 at the rear end of the side sill 43 of the frame said bracket also having an extension 44 in rear of the bolt 42 forming a lever bearing against the inner curved face of the sill member and ordinarily secured by a rivet or bolt fastening 4-5.

The construction illustrated in Figs. 9 and 10 is generally similar to that last described but in this particular instance it will be noted that the leverage extension 44 of the "frame attachment bracket 40 overlies the top orouter side of the frame member 43. this on account of the fiat angle of the rear end oi the member.

For the connection of the rear ends of front semiclliptic springs we may use constructions like tl: ,2 shown in Figs. 1 8, i142. and l5-li. i it each of those instances there braclmt H3 which adapted to he screwed by bolts, i? to the sill "I being suitably snake of in the and 8 and 15 and 16 the clamp 3 35 is directly carried by this bracket Whereas in the form shown in Figs. ll and 12 an attachment like that shown in Figs. 5 and 6 is used embodying parts 4:0 and 4:4. and secured by a shackle bolt 42.

For a three-quarter elliptic rear end suspension we may usea structure like that shown. in Figs. 5 and 6, as illustrated in Figs. 19 and 20, the leverage ext-s... .ion 44 in this case being designed to bear against the inner end portion of the upper leaf spring 47 instead of against a rigid frame member; Y

in Figs. 13 and 14: we have illustrated a form of attachment for the front ends of front springs similar in general respects to the constructions described except that in this case the clamps are disposed to hold the connecting link substantially horizontal and are provided with cooperating bearing pads el8-49 standing in overlapping relation and bearing on opposite faces of the interposed intermediate portion of the link. The upper bracket is designed to be attached to the forward end of the side frame member 43, being generally similar to the brackets illustrated in Figs. 5, 9, 11 and 19 in that it has ears 41 to fit the forward end of the frame pierced to receive the forward shackle bolt 50. This bracket also in this case is shown provided with rearwardly extending leverage projections 51 overlying the upper face of the side sill and secured down by a bolt or rivet 52.

In Figs. 17 and 18 we have illustrated a form or front end connection for a rear scmielliptic' spring like the connection last described in. that the link is interposed between bearing surfaces to operate as a cushion but differing from that form in that the clamps are arranged to support the link on a downward forward incline so as to adapt the same to take the forward thrust of the spring occasioned by the propelling effort of the rear wheel. The upper bracket member 53 in this case may be a special bracket or the one which is provided on the car for the regular rigid-shackle.

In the platform type of spring suspianlsion a connection is used such illustrated in Figs. 21, 22 and 23. The brackets 54, 55 which are attached to the longitudinal side spring and the transverse rear springs 56 and 57 respectively are generally similar to the channel brackets 26 already described ti clamp jaws 'ti .i an
