Application ,filed March 28, 1927. Serial K0. 179,157.
This invention relates to vehicle springs and-moreparticularly to springs for automobiles.
'The principal object of .this invention is to provide a spring so constructed that the weight orbody carried by this spring will tend-tobe carried under momentum without subjecting the body or weight to any sudden, upward, downward or tilting motion. a
A further object of this invention is to provide an upper and lower spring member, so arranged that the lower spring member constantly acts as a check against undesired movement of the body ,of'the vehicle such as upward or swaying movements which are common to vehicle bodies when suspended by springs of ordinary use whenthe vehicle is'traveling over uneven road surfaces.
Another object of the invention to'provide upturned ends of a spring which are drawn down and caused to be .at constant tension over a n--arc-shaped surface of two lever members functioning with. an upper and lower spring and atsuspension 'points from'the vehicle. 7
A still further object is to provide a spring device so constructed that the weight or body carried by said springs tends to becarried forward in a desired even way and not materially affected by alight or heavy load. lVi-th the foregoing and other objects in View which will appear as the "description proceeds, the invention resides in :the combina'tion and arrangement of parts and in the details of construction hereinafter de" scribed and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.
The invention is illustrated in the accompanying drawing wherein Figure 1 is a side elevation of the device.
Figure 2 is a sectional view taken on line Q2 of Figure 1. v
Figure 3 is a detail view showing a member of Figure 1.
Figure is a detail view of Figure 1, showing an end of a spring with an upturned end not under tension.
By referring to Fig. 1 it will be seen that I have-provided an ordinary vehicle axle 1 supported by wheels 2. The axle 1 is pro vided with support members 3 located near the outer end of said axle.
' As the description of *thisdevice; roceeds,
'tobe carried rests upon any ordinary-frame member 4. Rigidly attac-hedto this frame member 4 at a central point 5 by meansof clamps=6 is an upper spring .7 comprised o'f a'plurality of leaves.
' "By referring to Fig. 4; it will be seen that the outer ends 8 of the upper spring 7 is provided with an upper curve when .not under tension. The outer ends8 .as shown in Fig. 1 are under tension and securely clamped to levers'9 by means of clamps 10.
The outer ends 11 of'the levers'9 'arelsecured to the support members '3 "by means of shackles 12. The upper or inner ends 18 of the levers 9 are secured to a .pair of shackles .14. This pair of shackles 11 1 have their ends secured to a common pivot 15. This pivot lain-turn is secured to a lower spring 16 by means of a clamp 17 which holds the common pivot 15 at a central point on the lower spring '16, which isilocated di rectly underneath the, upper spring ,7. The outer ends 18 of the lower spring16 aresecured to shackles 19. .The upper ends 20 of-the shackles -l9rare securedito yoke shaped membersQl'in such amanneras to allow for the clearness of the levers-9 at points 22 so that levers f9 may be allowed a desirable range of movementwwhen the vehicle wheels 2 are subjected to uneven surfacesiofa -road-' way. The upper ends 23 of the yoke shaped members 21 are rigidly secured at the outer ends of the frame member 4 by any desirable means.
By referring to Fig. 8 it will be seen that 9 automatically shortening or lengthening the range of the spring 7 and to utilize the upturned ends 8 of the spring 7 when under tension, as the wheels 2 of the vehicle or the weight carried upon the frame member 4 are subjected to such movements as to cause an upward or downward movement of the inner ends 13 ofthe levers 9.
It is obvious that the upper spring 7 may be made of any desired strength and length in order that the same may function within a range limited within its suspension. It is also obvious that the lower spring 16 may be made in varying lengths and strength in order to meet varying conditions which it is desirable to meet in constructing a spring device for varying roads and various constructions of vehicles. It is believed that under ordinary conditions the lower spring '16 should be built so as to be more flexible than the upper spring 7 in order to allow for a longer range ofupward and downward. movement of the wheels 2, without subject ing the load resting upon the frame member 4 to upward thrusts and rebounds or swaying or tilting movements. One of the common objections to springs utilized for the purpose of carrying loads is that very little consideration has been given to the undesirable action of springs which are set in motion when a vehicle travels over uneven surfaces. These undersirable actions of springs cause rebounds of the load carried and subject the wheels to undesirable downward thrusts into depressions'in a roadway.
In this invention these undesirable actimis of springs have been considered with a view of reducing these objectionable features to the minimum. In the construction shown and described it is obvious that the lower spring 16 when placed in proper assembly in connection with the other elements of the device should be under constant tension in order that the up turned ends 8 of the upper spring 7 are drawn down and also under constant tension, thereby producing reserve energy in the outer ends 8 of the spring 7 to be used to minimize the tendency of the wheels to be dropped violently into depressions of the roadway. In regard to the lower spring 16,
it is obvious that when this spring has been assembled, as above described, there is a constant downward pull at each outer edge of the frame member 4:, thereby acting asa snubber for checking rebounds that would otherwise result when a vehicle is traveling over uneven roads.
What I claim is:
combination with an axle and support members attached thereto, two levers inserted between two springs, the outer ends of said levers pivotally connected to the supports attached to the axle, the upper spring rigidly secured at a central point to a frame member to which is attached a body, a lower spring and means for securing outer ends of said lower spring to outer ends of the frame member above mentioned, inner ends of said levers pivotly attached to said lower spring, a curved upper surface on each of said levers, upturned ends of said upper spring, means for keeping said outer "ends of upper spring under constant tension, substantially as described for the purpose set forth.
2. In a device'of the class described, an axle and support members attached thereto, two levers inserted between two springs,the outer ends of said levers pivotly connected to the supports attached to the axle, the upper spring rigidly secured at a' central point to a frame member to which is attached a body load, a lower spring and means for securing outer ends of said lower spring to outer ends of the frame member above mentionethinner ends of said levers pivotly attached to said lower spring, a curved upper surface on each of said levers, upturned ends of said upper spring, means for keeping upper and lower springs under constant tension, means for keeping outer ends ofupper spring pulled down against curved upper surface of each of said levers and under tension.
In testimony whereof I afiix my signature.
