DEVICE FOR CONTROLLING SHOCK.

Specification of Letters Patent.

Patented Nov. 19, 1918.

Application filed December 11, 1916. Serial No. 136,334.

To all whom it may concern Be it known that I, CHARLES BRYAN BILL- INGHURST, a citizen of the United States, and a resident of Pierre, in the county of Hughes and State of South Dakota, have invented an Improvement in Devices for Controlling Shock, of which the following is a specification.

My invention is an improvement in devices for controlling shock, and has for its object to provide mechanism for use in connection with motor vehicles of every character, for absorbing shock and jar resulting from the movement of the vehicle over the road and wherein an improved form of hanger connection is provided for interposition between the body and the axles of the vehicle.

In the drawings:

Figure 1 is a bottom proved device.

Fig. 2 is a partial rear view of a motor vehicle provided with the improvement.

Fig. 3 is a partial perspective view of the device looking from below.

The present embodiment of the invention is shown in connection with a motor vehicle, being arranged between the body 1 and the springs 2 which are mounted on the axles 3. Inner and outer frames 4 and 5 are provided, the said frames being substantially rectangular in outline, and of channel material, as shown, the inner frame 4 being arranged with the channel inward, while the outer frame 5 is arranged with the channel outward. That is the body portions of the material of the two frames are adjacent.

The outer frame 5 is provided at each side, and near the ends of the sides, with depending standards 6, each standard having at its lower end a pair of laterally spaced inwardly extending lugs 7, and each pair of lugs is connected by a pin 8. The inner frai e 4 is provided rt each end with a pair of similar standar s J. the said standards 9 being?' near the ends of the ends. and each sizzndam 9 ii p:'o" dcd at its lower end with :i'pair of outwardly facing laterally spaced lugs 10. crcIi pair of lugs being connected by a pin 11. Adjacent each standard 6 the inner frame is provided with a pair of lugs 12. and cccb hair of lugs 12 is connected by plan view of the ima crors pin 13. Adjacent to each standard 0 the outer fr me 5 is provided with a pair of dependin lugs 14.:1nd each H'UX ot lug: is connc .ed by v. cz'css pm 13. 'lhe pins 15 are directly above the pins 11 and the pins 13 are directly above the pins 8, and each pair of pins 813 and 11-14, is connected by a hanger 16 and 17, respectively of flexible non-elastic material, as, for instance, leather.

In the present instance, each of these hang ers is composed of a loop engaging the pins, the intermediate portions of the loops being secured together by rivets or the like. The inner frame 4 is connected with the body 1 in any suitable or desired manner, and the outer frame 5 is connected with the springs 2 shown. Thus the inner frame and the body are suspended from the outer frame and the springs by non-metallic flexible.

hangers, which interrupt any vibrations transmitted from the outer to the mner frame. Both frames are cushioned against the road by the springs and the tires, so that a minimum of shock and jar is transmitted to the body.

In the drawings the flexible hangers are shown to be attached at the ends of the frames, but it is obvious that attachments could bemade at different parts of the frames; for instance, the pendants 9 and hangers 17 could be attached to the side members of the frame midway between the ends thereof, and the pendants 6 and hangers 16 could be attached to the ends of the frame.

As is known, all shock and vibration work upward from road contact, and go first to the ends of the outer frame, because the springs are attached at or near the ends. If there is a rigid metallic connection, between the body of the vehicle and the outer frame, these vibrations are directly transferred from the outer frame to the body. In the present construction, however, this direct metallic connection is broken or interruotcd by CITSTQ IEQ between the body and the frame liex'bl non-metallic connection". It is obviom that any shock making compression in he direction of the length of he (tn-metall c connection would be abrorbcd ly the sa d conne tion. The same is true with checks and jars lateral to the lfi,Qi,l1 of the said connection. The only thock or iar hat cculd by any possibility be tran fer ed dirc th would be those of tcrsoa in the length of the connection, and practice shows that thee rhocks are lessened and for the greater part eliminated. The straps do not :1 t a: cushions, but as interstantially "rectangula't frames, the inner frame being adapted to support the body, and the outer frame being adapted to be connected with the springs of the vehicle and I a flexible noi' -metallic connectionbetween the inner and the a outer frames for sup porting saidinner frame near the level of the outer frame, said connection comprising depending hangers on the frames and straps of flexible non-metallic .material between the hanger and th other frame.

2., A device for controlling shock in m0'- tor vehicles comprising inner and outer substantially rectangular frames, the inner framebeing adapted to support the body, and the outer frame being adapted to be connected with the springs of the vehicle, and a flexible non-metallic connection between the inner and the outer framesfor supporting said inner frame near the level of the outer frame, said connection comprising a pair of depending. standards at each side of theouter frame and at each end of theinner frame, and a flexible non-metallic strap con necting each standard to the adj acent frame.

3. Adevice for controlling shock in motor vehicles comprising inner or outer substantially rectangular frames, the inner framebeingadapted, to support the body, and the outer frame being adapted to be connected with-the springs of the vehicle, and a flexible non-metallic connection beixes-e11nie inner and outer frames for supporting said inner frame near the level of the outer frame, saidconnection comprising one or more depending standards at each side ofthe outer frame and at each end of the inner frame, and a flexible non-metallic strap connecting each standard to the adjacent frame. i

4. Means for controlling shock in motor vehicles, comprising inner and outer frames, one of said frames being adapted tosupport a body and the other being adapted for connection with the springs, depending hangers at the sides andends of the frames, the

hangers at the ends: being on one frame and the hangers at the sides on the other frame, and flexible non-metallic connections between the hangers and the otherframe.

H 5.. In amotor vehicle, means for controlling shock, comprising a non-metallic flexible' connection between. the body and the springs, said connection comprising supporting members for the body and other members for limiting the upward movement of the body with respect to the springs.
