SHOCK-ABSORBER FOR MOTOR-CARS.
Specification of Letters Patent.
Patented Na. 19,1907.
Application filed July 16. 1906- Serial No. 326.471.
To all whom itmay concern:
Be it known that I, ARTHUR DUTRIEUX, manufacturer, residing at Le Quesnoy, France, have invented certain new and usein Shock-Absorbers for Motorars.
This invention has for its object improvements in apparatus for softening the tre idations of, the springs of motor cars an the like and it is specially intended for avoidin the abrupt expansion of the compresse springs.
The apparatus differs from others hitherto made for the same urpose, on one hand by its eculiar form which ermits one to reduce to t e utmost not only t e space occu ied by the ap aratus, but also its weight an on the other hand by its organization with 'a view to easy working.
' The invention is fully described with reference to the accompanying drawings in which:
. Fi ure 1 is a diagrammatic view of the apparatus showing how it is fixed on the frame of the car and its connection with the axle of the wheels. Fig. 2 is a transversal section of the apparatus at an enlarged scale. Fig. 3 is a transversal section of the apparatus through the line X X of Fig. 2.
This apparatus is composed of a box or chamber 1, which seen on the front side has the form of a sector, and which is fixed on the frame 7 of the car. This box contains a pallet 2, working as a piston. The iston is oscillating within the box 1 filled Wit a coniquid (oil, mixture of water and glycerin,consistent grease, etc.) and in order to permit the liquid to pass from one side of the piston to the other, holes have been rovided through the piston, and through a iiexible plate fixed on the said piston in such a manner that the liquid can flow easily in one direction through the piston and on the contrary with difficulty in the other one. For this purpose, the piston 2, is traversed b. numerous small canals 15. A flexible plate 21 is applied to one of the faces of the piston 2 and is there fixed only by one of its sides 22, as to be lifted by pressure of the liquid, which traverses the canals 15 in the directionofthe arrow f. The flexible plate 21 has three or four holes 23, which are in the prolongation of the canals 15.
T e piston 2, having to oscillate under the rings, is
of which is fixed a lever 4. A connecting- -rod 5 is movably connected in one of its extremities at a convenient point of the lever 4 and in its other extremity on the axle 6 or on the hoop of the spring 8.
The box 1 (Fi s. 2 and 3) has a hub 9, in which is engaged the extremity of the axle 3 and a screw cap 10 destined to introduce the h uid. The box 1 is shut by a cover 11.65 w 'ch is fixed by means of bolts passin through the eyes 12. The cover is provided with a collar 13 to give passage to the axle and to receive the stuffing-box 14.
The axle 3 of the apparatus is rovided with a ring 17 beveled on its perip cry and the ring 17 is applied against a beveled shoulder made in the collar 13 of the cover 11 by means of a screw 18 pressing against the extremity of the axle 3.
A stuffin box 14 cooperates with this arrangement or obtaining the tightness of the joint. The small conuecting-rod 5 is pivotally connected in one of its extremities on a sliding socket 19 engaging the lever 4 on which it is fixed by a screw and it is ivotally connected in its other extremity a ove the axle 6. By this means. it is ossible to va the length of the arm of the ever 4, accor ing to the degree of sensibility, which is desired to be given to the s ring and accordin to the load of the car. 11 case the length 0 the connecting-rod 5 is insufficient to have the fastening-point sufiicientl far on the lever 4 a longer connection ro is used.
' As it is desirable that the apparatus be regulated according to the more or less great elasticity of the sprlngs a canal 25 is provided in the nave connecting the two compartments of the box together; the passage of the liquid through the canal is regulated by ascrew lug 26.- Likewise as it is desirable that t e smaller vibrations of the springs maybe freely produced without being hindered by the resistance of the liquid against me the iston small. grooves 27 have been made in t e walls of the box around the-medium position of the iston, facilitating the passage of the liqui from one side of the piston to the other during the smaller vibrations and on the contrary, the piston produces its whole moderatin effect as soon as the springs have been strong y compressed.
A safety valve 16 is provided in the piston 2 opening in the direction of the arrow f in case of a stron er pressure by which the apparatus would e injured.
The apparatus operates as follows: When the springs are in the normal position the piston 2 is in the middle of the box; when the I siprings are bent .the piston is moved in the flowing only through the ho es 23 of the plate 21 WlllCh are in the-prolongation of the canals 15.
Having so described the nature of my invention and hoW it is that What I claim is:
- s rin and body of a vehicle, a sector-shape 0 am er on sald body, a swinging pallet in said chamber having anumber of passages therein, a' yielding plate secured to said pallet near its center of movement and provided with holes opposite some of said passages but closed opposite others, and means connecting said springto said pallet .whereb the latter is caused to swin in correspon vence with the bending of t e former, substantially as described.
i 2. In combination with the supportin spring and body of a vehicle,
spring and body of a vehicle,
performed I declare proi'ecting out of the chamber, a 1. In combination with the .supportin I a sector-shape chamber on said body, a shaft passing through said shaft, a yielding plate secure against one face of said pallet and an adjusting screw passing through the wall of said cham- :ber back of said shaft, said chamber having a by-pass canal cut in its wall around said shaft and across the inner end of said screw, substantially-as described.
3. In combination With the supporting a sector-shaped chamber on said body, a swinging pallet Within said chamber, a shaft for said pallet lever on sai shaft, and a connecting piece adjustably secured to said lever at one end and to a portion of said sprin at itsiother end, substantially-as describe 4. In a device of the class described, a sector-shaped chamber, a swinging pallet Within the same, ayielding plate fixed against one face of said pallet, a safety valve in said pallet and a spring controlling said valve, substantially as described.
