SHUCKAIESQIRIBER,

specification of Letters State-11 1;, ,p t m y 11 1199140 Application filed November 5, 1913. Serial No. $99,308.

'0 all whom it may concern:

Be it known that E, Koren Sumo, a subject of the'Emperor oi l apamand resident of Reno, in the county of Washes and State of Nevada, have invented a new and useful improvement in Shock-Absorbers, of which the following is a specification.

lady present invention relates to vehicle springs, and more particularly to a spring mounting" equally adapted to the fore and rear ends of frame to he supported and involving a spring arrangement ror the purpose of neutralizingheavy strains and slid den jolts and jars, being therefore in the nature of a shock absorber.

The object of my invention is to provide an arrangement Which will be highly of fective in its action, and strong and durable in use and l. have shown an arrangement to this end in the accompanying drawings in which,

Figure 1 is a side elevation. illustrating the parts under normal pressure. Fig. 2 is a similar view showing the in the positions they will occupy under sudden unusual strain or an exc ssive load, and Fig. 3 is a transverse, vertical section alren on an en larged scale through certain oi the parts, suhst nti on the line 3-3 of 2.

ow to these figures, A indi rams, and indicates either rear axle, as the case may he. .l. lowe spring C is secured, loy means of a yoke or other connection 5, at a point adjacent to its inner end, upon the axle B and is suitably connected at its outer elongated opposite end to the adjacent end of the main frame A.

In the present instance I have shown the '2? spring arrangement as applied tothe rear portion of a vehicle in which case the rear end of the leaf spring; U will be connected, by link 0, to the roar downwardly and in uardly curved end of of a leafspring D, the opposite end of which is secured by a yolrc or other means upon the rear end of the frame. It is to he noted, however, that in applying a spring arrangement to the forward portion of the main frame A, the outer elongated portion of the lower leaf spring C is directly united with the usual downwardly curved forward portion of the frame.

Secured at a central point to the extremity of the inner short end of the leaf sprlng C is a second leaf spring E, it being noted ally support heavy loads.

that both the leaf spring 0 and leaf spring E last mentioned are disposed longitudinally with respect to the main frame and that the inner end of the upper spring E is connected, by a link 6, to the frame A, intermediate the ends of the latter,

As shown particularly in Fig. 8 the outer end of the second leaf spring E supports a transverse pin 6, to the laterally projecting extrenntles of which are connected the upper ends of spring arms F depending upon opposite sides of the elongated portion of the first spring 0. A yoke or band C is secured about the elongated portion of the first or lower spring 0 at a point between its outer extremity and the axle B, the lower portion of this yoke or band C having; transversely projecting pins 0 to which the lower curved or curled ends of depending sprlng arms F are secured as by means of transverse bolts, rivets or similar connections. In this manner the several spring parts inchfoing the upper and lower leaf springs E and "their connecting arms F act through one another to take up and neutralall sudden jolts and jars and to effectull claim:

1. in a shock absorbing spring arrangement of the character described, the combination of a supporting axle, a main frame, a longitudinally extended leaf spring secured at a point adjacent its inner end upon the axle, and having connection at its outer elongated opposite end to the adjacent end of the frame, a second longitudinally extended leatspring secured at its center to the inner short end of the first leaf spring, the inner end of the second leaf Spring being secured to the main frame at an intermediate point of the latter, a pair of spring arms secured to the outer end of the second leaf spring and having curved lower portions depending upon opposite sides of the first leaf spring, and a yoke secured about the first leaf spring at a point between its outer end and the supporting axle, and provided with laterally projecting portions to which the lower curved portions of, the depending spring arms are secured.

2. In a shock absorbing spring arran ement of the character described, the com 1- nation of a supporting axle, a main frame, a longitudinally extended leaf spring secured at a point adjacent one end and having connection at its opposite end with the i-lti main frame, a second leaf spring centrally connected to the short end of the first leaf spring and having connection at one end with the main frame and spring arms depending from the opposite end of the second leaf spring and having connection with the first leaf spring at a point intermediate its elongatedend.

3. In a shock absorbing spring arrangement of the character described, the combination of a supporting axle, a main frame, a longitudinally extended leaf spring secured at a point adjacent. its inner end upon the axle and having connection at its outer elongated opposite end to the adjacent end of the main frame, a second longitudinally extended leaf spring secured at its center to the inner extremity of the first leaf spring, the inner end of said second leaf spring being secured to the main frame, and spring arms depending from the outer end of the second leaf spring and having lower curved portions connected to opposite sides of the first leaf spring at a point intermediate the elongated outer portion of the latter.

4. In a shock absorbing spring arrange ment of the character described, the combination of a supporting axle, a main f 'ame, a longitudinally extended leaf spring secured at an intermediate point upon the axle and having connection at its outer end to the main frame, a second leaf spring intermediately connected to the inner end of the first leaf spring, the inner end of said second leaf spring being connected to the main frame, and spring arms depending from the. outer end of the second spring and having curved lower ends connected to the first leaf spring at a point intermediate the outer end portion of the latter.

5. In ashock absorbing spring arrangement of the character described, the combi nation of a supporting axle, a main. frame, a longitudinally extended leaf spring secured at an intermediate point to the supporting axle and having connection at one end with the main frame, a second leaf spring having an intermediate connection with the opposite end of the first leaf spring and having connection at one end with the main frame, and a flexible connection between the opposite end of the second leaf spring and the first leaf spring, at a point between the supporting axle and the frame connected end of the first leaf spring, substantially as described.
