SHOCK-ABSORBER.
Specification of Letters Patent.
Patented Nov. 15,1921.
Application filed December 16, 1920. Serial No. 431,240.
To all whom it may concern:
Be it known that I, ARANT J. KRABER, a citizen of the United States, residing at Pittsburgh, in the county of-Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Shock-Absorbers, of which the following is a specification. T his invention relates to shock absorbers for motor vehicles for neutralizing or minimizing the effects of shocks and jars thereto, and resist the throw of the car body under the influence of road inequalities.
Objects of the device are to provide a shock absorber of the character described, in a manner as hereinafter set forth, which will operate to resist abnormal throw of the road conditions, without liability of breaking the spring or racking the car, and whichpermits of lateral movement of the car body without cramping or binding the working parts of the absorbing device.
. Further objects of the invention are to provide a device of the class stated which is simple in its construction and arrangement, strong, durable and efficient in its use, readily installed, attractive in appearance, positive in its action, and comparatively inexreference pensive to manufacture.
. To the accomplishment of these and such other objects as may hereinafter appear, the invention consists of thenovel construction, combination and arrangement of parts herein specifically described and illustrated in the accompanying drawing, wherein is shown an embodiment of the invention, but it is to be understood that the device shown is merely illustrative of what isnow thought to be the best embodiment thereof and that various changes in the form, minor details of construction may be resorted to, without departing from the principle or sacrificing any of the advantages of the.
invention, which come within the scope of the claims hereunto appended.
In the drawing forming a portion of this specification and wherein like numerals of designate corresponding parts throughout the several veiws:
Figure 1 is a sideelevation of the shock absorber, in accordance with this invention,
proportion, and
mounted on the front axle with a portion, of the latter broken away. i
Fig. 2 is a top plan view of the sustaining lever.
Fig. 3 is a side elevation illustrating a slightly modified form of shock absorber mounted on the rear axle with portions of the latter broken away. i
Fig. 4 is a sectional view of the rear axle perch and associated parts.
Referring to the drawing, the application of my improved device is illustrated in connection with the front and rear axles of a Ford automobile, but it will be understood thatthe same may be associated with any type of motor car, or for any purposes, wherein it is found applicable.
In the illustrated embodiment of the invention 1 indicates the front axle of an automobile, having mounted therein the usual spring perch 2. The angularly disposed apertured upper end 3, of the perch 2, instead of being positioned to extend inwardly, is positioned to extend outwardly toward the adjacent wheel, thereby eliminating the necessity of providing a special perch for use in connection with my improved shock absorber.
The sustaining lever 4, extending longitudinally with respect prises the body portion 5, a pair of inwardly projecting spaced arms 6, 7, and a pair of outwardly projecting and depending lugs, 8, 9. The lever 4 is pivotally connected to the perch2, by means of the bolt 10 which passes through the apertures 11 in respective lugs 8, 9, and through the aperture in the upper end 3 of the perch 2 which is positioned between said lugs 8, 9. Ample clearance is provided between the lugs 8, 9, so as not to impede the vertical movement of the inner end of the lever during the operation of the device.
The under side of the body portion 5 of the lever 4, adjacent to the lugs, 8, 9, is formed with an aperture 12 by which the upper end of a link hanger 13 is 'pivotally connected by means of a bolt 14. The end of the main automobile spring 15 is pivotally connected in the lower end of the hanger 13 by the bolt 16.
The arms 6, 7, of the lever 4, are formed to the axle 1, comwith the angularly disposed depending inner ends 17, 18, respectively, which straddle the spring passing therebetween.
Fixed to the center of the axle 1, by means of a spring clamp 19, is a leaf sustaining spring having a yoke-shaped end 21 secured by a shackle 22. The yoke portion 21 forms a guide-way 23 for the travel of the roller 24, mounted therein and rotatably carried by the bolt 25, which latter is fixed in the apertures 26 in respective inner ends 17, 18 of the lever 4.
The sustaining spring 20 may be comparatively light, owing to the length of the bifurcated inner end of the lever 41- and the connection of the vehicle spring 15, through the link hanger 13, near the outer end of the said lever 4,
The yoke portion 21 of the sustaining spring 20 provides a compensating connection to. permit of a variable movement of the roller 2A in the guide-way 23 during the functioning of the lever 4. g The action of the sustaining spring 20 not only serves to neutralize the abnormal recoil of the vehicle spring 15, but normally acts to minimize the jolts and jars concomitant in the operation of the vehicle spring under ordinary conditions due to small inequalities of the road.
The modified form of the shock absorber, illustrated in Fig. 3 of the drawing, is identical in operation asthat of the preferred form shown and described above, but differs slightly in construction, owing to the difference in construction of the front and rear axles of the vehicle.
In the use of of the vehicle, vided, which is the device on the rear axle a special perch 27 is probolted, as at 28, to the hub 1 disk 29. The lever 30 is formed with a de pending lug 31 which acts as an abutment to limit the outward movement of the link hanger 32, and in consequence the lateral throw of the car body carried by the vehicle spring 38. The sustaining spring 34 functions identically to that described relative to the sustaining spring 20 of the preferred form.
Due to the position of the gear housing 35 on the rear axle 36 an independent sustaining spring is provided at each end of the both I the axle. .60
chored resilient axle and secured thereto by means of a spring clamp 37. In the preferred form the sustaining spring 20 is anchored at its center by a clamp 19 to the center of the axle 1, thereby providing the sustaining element for devices mounted on opposite ends of What I claim is:
1.A shock absorber comprising an ansustaining element having a yoke-shaped outer end, a sustaining lever having its outer end pivoted and further having a depending inner end, a link pivotally connected at one end to the sustaining lever and adapted to have its other end attached to a vehicle spring, said link carried by the lever intermediate the ends of the latter, and means to provide a slidable connection between the depending inner end of the lever and the yoke-shaped outer end of the sustaining element.
