Application filed April 29, 1924. Serial No. 509,828.

The present invention is designed to minimize shock, jolt and vibration of a vehicle when passing over an uneven surface, thereby addin to the comfort of the occupant and reducing the wear and tear upon the vehicle and motor to the smallest amount possible.

The invention relates more particularly to the vehicle spring, its disposition and the mountings therefor, the latter being attached to the body of the vehicle and constituting connecting, supporting and guide means.

Other objects andadvantages will be apparent and suggest themselves as the'nature of the invention is understood.

lVhile the drawings illustrate an embodiment of the invention it is to be understood that in adapting the same to meet different conditions and requirements, various changes in the form, proportion and minor details of construction may be resorted to without departing from the spirit of the invention.

Referring to the accompanying drawings forming a part of the application:

Figure 1 is a front view of part of a vehicle illustrating the application of the invention,

Figure 2 is a sectional view of one of the inner mountings for a quarter spring.

Figure 3 is a sectional view on the line 3-3 of Figure 2,

Figure 4 is a sectional view on the line 4-4 of Figure 2, and

Figure 5 is a detail sectional veiw on the line 5-5 of Figure 2.

Corresponding and like parts are referred to in the following description and (ilOSlgfnated in the several views of the drawings by like reference characters.

The numeral 1 designatesthe body of a vehicle and 2 an axle which is provided near each end with a spring perch 3 to which a quarter spring 4 is connected by means of a shackle 5. The springs 4 are laminated and are built up of leaves which may be connected in any usual or preferred way. As shown, bolts 6 connect the leaves at the inner end of the spring. A hanger 7 is pro vided for the inner end of each quarter to the body of the vehicle.

conform approximately to the outer ends of. the springs. The outwardly facing sides of the hangers 7 are open, as indicated at 8, to provide clearance for the inner ends of the springs 4, whereby the same may have a free vertical play. Helical springs 9 and 10 are disposed within each of the hangers 7, the one above and'the other below the springs whereby to cushion the action thereof. The springs 9 and 10 are secured to the respective springs 4 by means of the bolts 6. as indicated most clearly in Figure 4.

Abracket 11 is provided for each of the quarter springs 4 and is attached at its upper end to the vehicle body 1, and the respective springs 4 pass loosely therethrough so as to have a free vertical play but pre vented from having any relative fore and aft, movement. The brackets 11 function .as guides and act jointly with the hangers 7 to hold the springs 4 in given position, while at the same time admitting of vertical movement thereof to compensate for shock, vibration and jolt.

What is claimed is:

Shock absorbing means comprising oppositely disposed quarter springs shackled at their outer ends to an axle of the vehicle, oppositely curved hangers depending from the vehicle body and receiving the inner ends of the respective quarter springs, helical springs disposed within each of the hangers, the one above and the other below the quarter springs. and brackets depending from the vehicle body and loosely engaging the quarter springs and acting jointly with the hangers to prevent fore and aft movement ofthc quarter springs while at the same'time admitting of free vertical move ment thereof to compensate for shock, vibration and jolt. said brackets being relatively close to the sides of the body and materially spaced from the hangers.

In testimony whereof I affix my signature.

JOSEPH LEVESQUE.
