VEHICLE-SPRING. H

spring members being connectedwith the frame by` a link, each .of these spring members has a terminal, the terminals being disposed at` opposite sides of a connecting member which is normally secured to a frame or axle. Flanges with sleeves are bolted in the recesses, and these flanges are-disposed from the sleeves away from the frame, and in and against the adjacent terminals of the spring i members, so that bolts may be disposed v so through the openings in the sleeves in the flanges, for securing the flanges to the connecting member, and additional bolts may be disposed in openings in `the flanges, vand in the terminals of the spring members, for holding the terminals of the spring members in position. A spiral spring which is provided'is connected by tie members having turn buckles, with the link at one of the spring members, and with the frame at the other spring member, so that the spiral spring will give the desired resiliency, when the yvehicle on which" the spring is used travels over slightly uneven ground.'Y When the vehicle travels over very roughground,

the said spring members take up and do most of the work of the spring. lIn this way my spring is sensitive when 'such a' quality isdesirable, without'impairing its usefulness under other conditions.

IIn vehicle springsas they are now coni Vstructed most .of the breakage takes place on the rebound. This weakness is done away I rebound my spring memberswhich are of thejusual leaf-'spring type, will not bend,

but, on the contrary, they will straighten. This removes the danger of rupture on the rebound of the spring.

Additional objects of invention will appear in the following complete specifica- Specication of Letters Patent.

the views, in which- Figure l is an elevation showing my improved spring; F ig..2 is a sectional view on the line 2-2 of.Fig. 8 ,Fig 3 is a plan view of Fig. 2; and Fig. 4. is an elevation of one of the leather members, which are disposed between the terminals of they spring members and the connecting member. l

lBy referring ,tothe drawings .it will be seen that a lframe member` 5 is provided,

which may bepart of an automobile body,

and that this framemember 5 has the depending end 6 towhich the end 7 of the spring member 8 is articulated. The end 9 of the other spring member 10 is articulated to a link 11, this link 11 being articulated to the frame member 5 at 12.` f

The spring members 8 and 10 are construct ed each of a plurality of leaf springs, which fare secured together bythe clamps 13. 'A tie members 14 has aterininal 15, which is articulated to the'depending end 6 ofthe frame member 5, this tie member lfibeing connected with ya tie `n lember 16 by a turn A. tie member l8.is articulated at its end 19 to the link l1, andthe end 9 of the spring member l0, this tie member ,'18 being connected with a tie member 20 by a turn buckle 21. The tie members 16 and 20 are secured to the spirall spring 22. Disposed below the spiralspring 2 2 there is a connecting member23, this connecting mem-` befr 23 having recesses 24, one at each end in which the terminals 25 of the spring members 8 and l0 are disposed, these terminals 25 beingbent away from the frame 5, as

shown in Eig. 2 of the drawings.

As ameans gif-securing in the recesses 24 these 'terminals`25of the spring members 8 and l0, Iprovide flanges 26, which have Isleeves 27,-'through which the boltsf28 are disposed, these bolts l28 extending through at the sides of the recessesfl, It will be noticed that the `flanges 26 extend from. the

sleeves 27 away ffromlthe kframe 5, so thatv at each end ofthe connecting member 23 a ,bolt 30 may be disposedthrough the openmember` 23 In the drawings s1milar characters of lreif?- ingsl 31 inthe flanges 26, and also through openings S32/'in thelenf: rings, of lwhich the spring members'Send l are eonrxieted. This bolt 80 has a nut 33, which is disposed through an angular openi. 34, in a leather or other non-metallic mem r 35, this nonmetallic member 35 being disposed between the terminals 25 of the spring members B and 10,-and the ends fof the new.. The nuts 33 extend beyond the mem ers 35, into openings 37 in disconnecting member 23.

As my vehicle'sprin'g is constructed, the spiral spring 22 is delicate enough so that it will with vthis ends Af ende of ithe spring members 8 and '10, make 'the vehicle spring sensitive u to a certain point, ont 'beyond that point Ehe bodies of'the spring 'members 8 and 10 'will 4'occasion the vehicle spring to stiien so 'thatwhile my Vehicle spring has the necessary sensitiveness, when' this 'quality is desirable, it 'does not lessen its eiectiveness under other conditions.

While the ordina-ry vehicle is very apt to rupture on the rebound, this danger is wholly eliminated by my vehicle spring, for on the rebound the spring ymembers 8 and 10 straighten, instead of beingbent ebnormally, as is the case 'with vehicles rings of other types. The connecting mem er 23 is secured to an axle el) by the members eil.

It will be understood 'that with the connection as it has Vbeen described the spring will not be rigidly secured to the axle, but when in use will have a movement which will relieve the spring from much strain.

Having thus described my invention, I Gleim as new and desire "to secure by Letters Patent:

1. In 'a vehicle spring, a frame, two spring members connected with the frame, a connecting member, the sring members having terminals bent away rom the frame, two flanges, one secured at a side o'f each terminal, and pivoted means for securing the flanges to the .connecting members.

2. In a vehicle spring, a Trame, two spring members connected with the frame, a. connecting member, the s ring members having terminals bent away rom the 'frame and one disposed at each side 'of the connecting member, two flanges disposed against the outer sides of the terminals, and pivotal means for securing the flanges to the connecting members with the flanges eX- tending fronithe said means and 'away from the frame.

3, In a vehicle spring, a frame, two spring members connected with the frame, a connecting member, the spring members having terminals bent 'away from the frame and one disposed at each side of the c'onnecting 'I member, two flanges disposed against the outer sides of the terminals, pivotal means for securing the flanges to the connectingrom 'the seid means :and eway from -t e frame, and means .for'securirm the lla-nges to the terminals.
