shackle connection, which will ,require little or no attention in. use, eliminate the usual problems of lubrication, and which in operation'will noiselessly cushion vibrations, road shocks or the like.'

A further and important object of the .1nventionv is to provide a resilient mounting which will'readily yield to permitrel-ative movement-of the spring and frame in a longitudinal direction, but will be resistant to the highly objectionable side sway between the parts. l l Y Other objects and advantages will be ap-y parent fromthe following detailed specification'A of a vpreferred 'embodimentof the invention, 'taken in' connection with the accompanying drawing, in which- Figs. 1 and 2 are detailviews, partly in section'and partly inelevation, vshowing respectivelythe connections between opposite ends of the rear spring with the chassisframe.

Referrin more specifically to the drawing, the re erence character 1 represents one of the longitudinally extending channeled` side members of the 'chassis frame, which terminates at its rear end in ahorn ordownturned` portion 2, and 3 indicatesl a semi` elliptical multideaf spring to flexibly support the frame4 on the rear axle. While reference herein is only made-toene of the rear s rings, it will be obvious that the same shac e connections are for use with each of the vehicle springs, both at .the front and the rear. i j

The driving connection for the front end' of the spring 3 is (illustrated in Fig. 1, which constitutes a. pivotal mounting therefor. In this case, there is provided a block of vcushioning material, preferably lconsisting of a- Y body of rubber or other elastic substance 4, having integrally lembedded therein by vulcanization or the like,a link or strap 5` of flexible, .but inextensible material, such as :fabricj: thlor brous material, or if desired,

` vthis s'tfra'pfiinay be formed of thi'n sheet metal haying a comparatively high degree of resillency. A retainer cup 6, pressed or stamped from sheet metal, is riveted or bolted a nut 9: Spaced longitudinall 1927. Serial No. 173,384.

at 7 to the bottom flange ofthe channel frame member 1,#and the cushioning block is contained within this cup, and may be placed y therein under a slight initial compression.

The dexible strap 5 is bowed upwardly, due either to preforination or deformation 'of the block within the cup, and a fastening bolt 8 passes upwardly through the block at the bight of the bowed strap and is secured to the bottom flange of the frame member 1 by on either side of the bolt 8 are fastening olts lil-10' extending downwardly through the block at opposite ends of the strap 5,-being secured to the front end of the spring -3 by nuts 11-l`1.

provides a link between the spring and frame, which, since it is inextensible, does not permit side sway or relative ltransverse movement between the longitudinally spaced. fastening bolts. -Howeven the bow or Vlongitudinal undulation in the strap allows its inherent flexibility to act in a longitudinal bottom of the horn ,2, is provided at either end with an in-turned ear or channel portion 14 into which channels are inserted ribs or beads 15 of the resilient block. The elastic cover 16, surrounding the bowed or undulating strap 17, extends beyond the ends of the strap for some distance, and .is preferabl provided with transverse openings 18, whic serve to increase its elasticity and facilitate longitudinal distortion. The fasteningbolt 19 extends-through the block at the bight of the strap 17, and is secured to the spring end The strap 5 Within its elastic envelope 4 thusy by nut 20. Here again, the bowed strap'l'( reinforces the block against sidesway, but readily yields or flexes with the longitudinal distortion of the elasticbodv 16. upon deection and extension of the vehicle spring 3.

While the subject matter has, vdescribed more or less specifically"in its'l preferred. form, it is to be understood that the invention is not limited tothe exact details set forth, but that such modiiications may be ya chassis frame and a vehicle spring, of flexible connections between the ends of the spring and the frame, including elongated blocks of elastic material, longitudinally undulated fabric reinforcement strips lembed ded within the material, retainers for said blocks .carried by one of the members to be connected, and 'fastening bolts extending through the blocks and passing through both the elastic material and the'embedded fabric and secured to the other of said members to be connected.

2. In a motor Vehicle, the combination with a chassis frame and a load supporting spring, of a hinged connect-ion therebetween, including a bowed flexible link having its op osite ends secured to one of said parts and its ight secured to the other of said parts, and elastic cushioning material interposed between the link and said parts.

3. In a motor vehicle, the combination with a chassis frame and a load supporting spring, of a hinged connection therebetween, ineludin a bowed flexible link and a relatively thick envelopeof elastic cushioning material Surrounding said link, means securing the opposite ends of the link to one of said parts and means securing the intermediate bight thereof to the other of said parts. i

4. In a motor vehicle, the combination with a chassis frame and a load supporting spring, of a flexible connection therebetween, includf ing a block of elastic cushioning material and a flexible but'inextensible strap inteorally united with said block, said strap eing bowed in the direction of relative movement of the parts, a container for the block carried by one of the arts, and a fastenin element associated Wit the block at the big t of said Ibowed strap and secured to the yother of said parts. 5. In a motor vehicle, the combination with a chassis frame and a load supporting spring, of a flexible connection therebetween, including a block of elastic material and a bowed strap of flexible fabric embedded within said elastic material, means to secure the ends of the block to one of the parts, and means to secure an intermediate portion of the block at the bight of the bowed fabric strap to the other of said parts.

6. In a motor vehicle, the combination with a chassis frame and a load su porting spring,

of a flexible connection there etween, mcluding a block of elastic/material, a flexible but i-nextensible strap embedded within said elastic material in'nndulating relation throughsecure the block to the respective parts at longitudinally spaced apart points.
