Continuation of application Serial No. 5126,76@ filed March 25, i922. This application filed November 22,

T0 all whom t may concern:

Beit known that I, SIDNEY B. SEGURA, a citizen of the United States, residing at Houston, in the county of Harris and State of Texas, have invented certain new and useful Improvements in Shock Absorbers for JAutomobiles, of which the following is a speciiication, reference being had to the accompanying drawings.

It is the purpose of the present invention to provide a device of this kind, by which the shocks due to the rebound movements of the automobile may be absorbed, as well as the shocks resulting from the downward movements of the body.

Heretofore, the shocks resulting from the rebound movements, have been absorbed by cushions above a member of the body, and the shocks created by the bod7 on its downward movements have been absorbed by cushions below said member.

However another purpose is to reverse the order of this arrangement, thatris to say, to absorb the shocks incident to the downward movements of the body, by cushions disposed above an oscillatory member, and to absorb the shocks incident to the rebound movements of the body, by cushions arranged below said oscillatory member. It has been found that this order of arrangement absorbs the shocks more uniformly, enabling the occupants of the vehicle to ride with greater comfort and ease than has been accomplished before.

A further purpose is to provide an oscillatory lever or member, one end thereof being connected to the usual leaf spring of the body, and the other end operatively mounted between upper and lower cushions whereby the shocks, resultingA from the downward movements of the body, are absorbed by the cushions above, and those resulting from t-he rebound movementsv of the body, are absorbed by the cushions below.

A' still further purpose is the provision of an improved means for mounting said cushions and the oscillatory lever or member, whereby these results may be accomplished more effectively and ata relatively low cost.

Also it is the aim to provide shock ab` sorbers applicable to the forward and rear springs. and axles (preferably of a Ford automobile). without making any material Serial No. 602,574.

alterations inthe construction of the automobile.

It is to be understood that the particulars herein given are in no way limitative `and that while still keeping within the scope of the invention, any desired modifications of detail and desired proportions may be made in the apparatus according to circumstances.

The invention Ycomprises further features and combination of parts, as will be hereinafter set forth, shown in the drawings and claimed.

In the drawings Figure l is a rear view of an automobile showing the rear shock absorbers mounted in position, showing one ofv them in section;

Figure 2 is a view in front elevationv of an automobile, showing the forward shock absorbers, there being a portion of the forward axle in section, showing how the hanger for the lower cushion'is reinforced relatively tothe axle;V l Figure 3 isa, vertical sectional view on line 3-3 of Figure 1,showing the construcf ltion ofthe shock absorber at right angles to that shown in the preceding figures;

Figure l is an enlarged detail perspective view of the rearv hanger; Figure 5 is a detailview ofthe U-shaped saddle which straddles the upper and lower cushions and has the lower'ends of its arms operatively connectedto they axle.

Figure 6 is adetail perspective view of one of the spring abutments.

Referring tothe ,drawingsl and 2 desig nate the forward andrear axles of the automobile, and 3 and 4; denote the forward and rear springs thereof, while l5l and 6 designate the forward and rear hangers of the shock absorbers. Each hanger rises from the axle, and near its lower portion is provided with a lateral plate 7 which carries a cup 8. The lower portion of each hanger is provided with a Ushaped crotch 9, whichstraddlesthe axle, there being a bolt 10 passing throughV the extremities of the arms or side walls of the crotch and engaging below .the axle, to securely anchor `the hanger ina perpendicular position on.

the axle. It is, to be noted that the hanger, the plate, and the cup are all constructed, in a one-piece casting, soas toV insure rigidity and:strengtlr he'gouterl end of the'vplate 7 of eachy rear hwger is connected at ll to the rear axle brake housing, which is adjacent .the rear hub brake drum.

The construction of each forward hanger is modified, to the extent of arranging the bolts a adjacent the outer end of the plate 7 of the hanger, instead of at the inner end. Furthermore the inner end of each forward hanger has an extension or lug 12, which enters an opening in the forward axle, and receives a nut on its lower end, which nut bears against the under face of the axle, and by this construction the forward hanger is held in place and prevented from moving inwardly.

rlhe upper end of each hanger is bifurcated, and arranged between the arms 13 caused to be formed by the bifurcation 14 and fulcrumed upon a pin 15 is a lever 16. rlhe inner end of the lever 16 is downwardly turned as shown at 17 and is connected to a link 18, which in turn is fastened at 19 to a leaf spring 2O of the automobile rllhe outer end of the lever 16 terminates in a head 21, which extends at right angles to the lever 16, in a direction above and below the lever. The upper and lower ends of the head operatively engage sockets 22 and 23 of the reversely disposed cups 24 and 25. Arranged above the cup 24 is an additional cup 26, the upper face of which is provided with a recess 27. The cups 8, 24, 25 and 26 are spaced and are arranged in axial alignment and cooperating between the cups 8 and 25, and between the cups 24 and 26 are coil springs 28 and 29. These springs 28 and 29 are under compression, therefore the tendency of each spring is to expand.

Straddling the cups is a saddle 30, so that the upper transverse portion 31 of the saddle will engage the groove or recess 27 in the upper face of the cup. ln other words the transverse portion 31 of the saddle is countersunk in the cup, so that the upper face of the transverse portion is flush with the upper face of the cup, there being a suitable bolt 32 passing through the transverse portion and into the cup, to secure the saddle and the cup 26 together. The arms of the saddle extend downwardly on opposite sides of the various axially aligned cups 8, 24, 25 and 26, so that their lower ends will protrude below the under face of the axle. The extremities 33 of the arms of the saddle receive bolts 34, which pass under the axle, thereby securely fastening the saddle in position.

The sockets 22 and 23 are of sufcient size to permit the head 21 to move freely therein, so as to compensate for the oscillatory movement of the lever' 16. 1t is well understood that when the wheels of the vehicle come in contact with a gully or depression in the roadway the body of the vehicle moves downwardly very sudden, creating shock. rlherefore the shock incident to the downward movement of the body has been absorbed by cushions or springs under a member carried by the body. ln the present instance, it will be noted that the cushion or spring for absorbing a shock 1ncident to the downward movement of the body is located above the lever 16, therefore, when the body moves downwardly, the lever 16 is oscillated, causing the head 21 to move upwardly additionally compressing the spring 29, and allowing the spring 28 to expand. ln shock absorbers heretofore produced, the shock incident to the. rebound movement of the body has been absorbed by means above a menibeixcarried by the body. However, in the present case the cushion or spring for absorbing the shock incident to the rebound movement of the body is located below the lever 16. therefore, well understood that when the body in the present case makes its rebound movement, the head 21 of the lever 16 moves downwardly, compressing the spring 28,

and allowing` the spring 27 to expand, *f

thereby absorbing the shock, as a result of the rebound movement of the body.

lt will be noted that due to the links 18 the body of the vehicle is permitted to have lateral play relatively to the hangers 6, for it is clear that if it were not for the links 18, considerable lateral strain would be imparted upon the hangers 6, as a result of any movement of the body in a horizontal or lateral direction.

This application is iled in continuation of the application of Paul A. Leckrone and Sidney B. Segura, filed March 25, 1922, Serial No. 546,764.
