Specification of Letters Patent. Patented Nov. 30, 1909.

Application led January 23, 1906, Serial No. 297,457. Renewed April 3, 1909. Serial No. 487,767.

mechanism may be taken up and also to substitute for the sprocketchain shown in said application a connecting bar in place thereof for connectingv the running gear of the car with the ratchet mechanism mounted on the bed thereof. I .accomplish these objects by means of the device herein described and shown in the A4accompanying drawing inl which Figure-l is an elevation of my device in place on a car, a fragment only of the car andthe supporting spring being shown.

' Fig. 2- is a vertical longitudinal section the projectin -ratchet shell vreferred to the main springs yvill permit the taken on the dotted line 2-.-2 in Fig. 3 looking in the direction indicated by the arrows placed thereon. Fig. 3- is a transverse central vertical section taken on dotted line 3 3 in Fig. 1 looking in the direction-indicated by the arrows thereon. Fig. 4;- is a fragmentary view of the annular metallic 1friction ring-showing the hub-engaging ,kiln the drawing A is the frame which supports the body of the car to which my device is secured and which rests upon the supporting spring B. Theusual clips D secure the spring to the-axle C and extend above and hold the plate E in rigid engagement with the spring. A swinging bar F is pivoted at its lower end to the plate E extending upwardly and is ivotally connected to arm (21 integral with the In, this device like the one axle to be thrown rapidly upwardly in the direction `'of the body of the car. when an obstruction is' encountered inthe road and at the same time 'will prevent the from exerting theirgnnrmalstrngthito sudden'ly throw the body-df the Vcar ,upwardlythe wear on l. the friction leather rings 1n theA ratchet.

lsprings y und away from the springs. I have in this instance provided a roller ratchet combined with an adjustable clutch which will permit encywhen the wheel is thrown up suddenly springs from immediately exerting'their full. impulse upward on thebody of the car, but will permit them tol exert that impulse gradually and elevate the body of the car easily thereby vided to prevent the same.

The ratchet clutch vmechanism contained frame A of the car as 'shown in Fig. l by. the bolts H extending through ltlneiange I on the frame I of the ratchet.4 bolt J extends. outwardly through the frame I and shell Gand secuifgs the ratchet mechan- Aismthereto as showny in enlarged section in Fig., 3. Surroundingthisfbolt and lying between the head thereof and the hub I of the frame is mountedthe spiral spring K. The object of this spring is to take up pads or washers L which extend around the hub l ofthe frame are subjected to and I .accomplish it in this way: On the outwardly projecting Screw threaded end of this bolt is a nut M which serves to'hold the flange .N of the annular ri-nglNT in spring pressed engagement with the annular metallic friction ring O and crowd the same firmly against the leather clutch washer L lying next thereto. The ring O has a downwardly projecting lug O which extends into the seat I in the hub of the frame I and prevents the ring from rotating on the hub, but permits a longitudinal movement thereon of the ring allowing the ring to move inwardly on the hub and always hold the clutch pads spring pressed no matter how much wear may be had on the leather pads. 'f

The ratchet wheel Q, carrying ratchet teeth Q on the periphery thereof-,is loosely `mounted on the hub and 'carries 1 on the periphery thereof roller seats for the re- 'ception` of the 'roller ratchets R'. These ratchet rollers are disposed in the usual way around the ratchet wheel and in the roller seatsl provided therefor and are the springs to retain their unlimited resili in the direction of the body of the car, but' the clutch mechanism Awill prevent the and thereby prevent the usual jar occasioned when no clutch mechanism prointhe shell -G is detachably secured yto the'- the wear that the annular leather clutch A i iiioniiiei iii ri on iiiziei'iiil hei'i imi nini i ei.' dif. i :i riwerermi ceiniifeiini; '.'sziii inner disks, e lee snrr-iiiinim eziiil :ininiliis and if i, iers iii the reeesees in anni iinniiliis 70 Jy nid ing ring nizrv ireigelv rein one fiioii, lint will eiinse said friction disks to operate when iiiovcd in the "te direction, in x:ins for :idjnstiing the i `iid einer sind inner disks epoxi 75 "'eiinl.y und ininipeiisnliei innig seid pressure ii n ixed to seid locking1 ring inni s! attached to ii Second iirin whit-ii ',lfhen if. n e, shock absorber, the combination -vi'itii 'tr-anichnving :i huh, a holt having; 'i
