VEHICLE SPRING;
This inventiony relatesv to vehicleJ springs, and the purpose of the. invention is to provide suitable springs for eliminating or 'reducing the jars of vehicles when passing over rough roads, and also for eliminating or reducing the undesirable effects of the rebounds of the vehicle as it is forced upwardly or, downwardly by the springs. Other objectsv of the invention will be apparent from a consideration of theaccompanying drawings andthe following description thereof.
Of the drawings, Fig'l is a rear elevation of a vehicle chassis with springs attached thereto, which embody the features of my invention; and Fig. 2 is a section along the line 2 2 of Fig.l 1.
Iny carrying out my. invention I replace the ordinary elliptical or semielliptical leaf springs, or other springs, with coil springs so arranged as to provide resilient means tending to prevent relative movement of the axle andthe chassisframe, andithus to reduce the undesirable effects when the wheels go over obstructions or pass into depressions, andA also to reduce'the effects of the rebound of the chassis in either case. While I show and describe herein particular details of my preferred form of apparatus, yet it is to be understood that modifications Amay be made in details thereof without departing from the spirit of my invention as set forth in the attached claims.
The frame 3 of the vehicle, which in this instance is an ordinary automobile, supports brackets 4 to which are pivoted cylinders 5, having restricted open ends 8. In the cylinders 5 are pistons 6 having stems 7. Between the restricted end and the pistons in each cylinder is a compression spring 9. The upper ends of the pistons are pivoted to a head of a piston stem 11. To the other end of the piston stem 11 is a piston 12 which is mounted in the cylinder 13. The cylinder 13 is fixed by any suitable means such as the casing 14 to the axle 15 .of the car, and a compression spring is mounted in the cylinder 13 on the stem 11.
From a consideration of this apparatus, it will appear that if the wheels 17 which are mounted on the ends of the axle 15, strike an obstruction so as to elevate one or both ends of the axle, the springs 9 will be compressed as the axle 15 will be forced towards the frame 3; and the pistons 6, be-
ingy connected by the piston: stems 7 to the..
axle;v This will give a cushioning effect.V
which@willimaterially reduce the jar on-.the
frame.; TalleI springs, howevem will, as is; usuallm such1cases,.tend to force theA framev upwardly somewhat, but thistendency will be overcome or.y reduced by the effect of the compression4 spring lxwhich will be com? pressed'thereby; Onthe otherhand, if one" ofthe wheels passes into a depressionthe tendency ofthe frame to pass downwardly. will be reduced: by theV compression spring: 9,in'thecylinders 5, andat the same time the compression spring 16 willreduce the effect; .ofi therebound as the frame is forced up` wardly by the springs 9i In ageneral way,
this describesthe action of: the springs withf. reference to the relative movementl of the frame and the axle.
However',l toassist inl thel action of thel springs andito reduce the noise and friction liquid to pass from one side Vof the piston to the other as it operates. This not only lessens any wearing tendencies of the parts, but it cushions the pistons, thus reducing the strain on the springs, and also the tendency of the pistons to strike against the ends of the cylinders. Also, I place in the lower end of each cylinder a disk 21 of yielding material such as rubber which still further reduces the jar and noise of the pistons as they strike on the ends of the cylinder.
In order to avoid any liability of the frame striking the head 10 or other portions of the apparatus, the brackets 4 have arms 22 which curve outwardly from the frames and thus the beams of the frame are at one side of the spring apparatus and cannot strike the head 10. By the Various arrangements for preventing rebounds and jars the severe stress which ordinarily would affect the springs is eliminated or so reduced that liability of fracturing the springs is substantially eliminated. The cushioning effect of the liquid in the cylinders and of the rubber disks 21 and the counter effects of the spring 13 with reference to the springs 9, eliminates the stress on the springs sufiiciently to prevent fractures thereof.
I claim as my invention:
1. In a vehicle having a frame and an` axle,a cylinder pivoted to said frame and having a restricted open end, a piston in said cylinder, a stem fixed to said piston and projecting out et' said open cylinder end, a compression spring in said cylinder between said piston and restricted end, and resilient means pivotally connecting the projecting end of said stem with said axle, said means comprising a second cylinder with its closed end rotatably mounted on said axle, and having a restricted open end, a piston in said second cylinder, a stem fixed to said piston and projecting from said second cylinder, and means pivotally Y connecting the projecting ends oli' said two stems.
2. In a vehicle having a frame and an axle, a cylinderl pivoted to said frame on each side of said axle and having a restricted upwardly extending open end, a piston in each ol said cylinders, a stem ixed to each of said pistons and projecting upwardly out of said vopen cylinder' end, compression spring in each of said cylinders between said piston and restricted end, resilient means pivotally connecting the projecting end of each of said stems with said axle, said means comprisinga second cylinder with its closed end rotatably mounted on said axle, and havinga restricted open end, a piston in said second cylinder, a stem ixed to said piston and projecting from said second cylinder, means pivotally connecting the projecting ends of said three stems, and a liquid in each of said cylinders.
insecte 3. ln a vehicle,.a frame and an axle, two cylinders pivoted to said frame and posi.- tioned above but on opposite sides of said axle, the lower ends of said cylinders being closed and the upper ends having restricted openings, a piston in each cylinder, a stem lixed `lo each piston and projecting upwardly from its cylinder, a compression spring on each stem between the piston and the upper end of the cylinder, and resilient means connecting the projecting end of each oi said stems to said axle.
Ll. ln a vehicle, a 'frame and an axle, two cylinders pivoted to said frame and positioned above but on opposite sides of said axle, the lower ends or said cylinders being closed and the upper ends having restricted openings, a piston in each cylinder, a stem 'ixed to each piston and projecting upwardly from its cylinder, a compression spring en each stem between the piston and the cylinder end through which the stem projects, and resilient means connecting each of said stems to said axle, said means comprising a third cylinder' with its closed end rotatably iixed to the axle and with its other end open but restricted, a piston in said third cyliilder, a stem l'ixed to the piston of said latter cylinderl and projecting from the cylinder, a coil spring within Said cylinder encircling` said stem, the projecting ends of all of said stems being pivotally connected.
