original no. 1,596,445, dated August 17, 192e, sex-iai No. 101,681, sied April 13, 192e. Application fer reissue led December 8, 1926.
' invention-relates to new and useful irnprovements in a shock absorber, which 1sV vide a shocklabsorber including a cylinder divided into chambers by .apiston slidable within the cylinder, the` former having a pair of opposed valve controlled passage- Ways to permit the transfer of air from one chamber to the other, while the cylinder is` provided with one or more valve controlled air passageways at each end thereof, one of,
which permits the egress -oflalr from the cylinder, while the other, when used, permits ingress of air.
' A further obiect of the invention is to pro vide an exceedingly simple, effective and inexpensive shockv absorber, which will be strong, durable and efficient in operation.
A still further object of the invention is to rovide means for attaching the shock absorber to a vehicle andto provide means -for allowin a certain sidewise movement of the parts w en used. f
With these ends in view, this invention consists in the details of construction and combination of 'elements hereinafter set forth :and then specifically designated by the claims.
In order that those skilled'in the art to which this inventiony appertains, may understand how tov make and use the same, I wi-ll describe its construction in detail, referring by numerals to the accompanying drawings forming apart of this application, in which: f i
Figure 1 illustrates one method of attaching one of the shock absorbers to the frontof an automobile of a certain type.v
Figure 2 illustrates the method of'fasten ying 'a shock absorber to the rear of'an automobile.'
Figure 3 is an enlarged vertical sectional view` of the shock absorber. q
Figure 4 is a plan lview thereof; and Figure 5 is a sectional viewof a ball and socket joint, which will permit `universal movement of the shock absorber relative t0 the part to which it is attached. Y
Serial No. 153,435. V Y.
'l In carrying out my invention asl herein embodied, represents the cylindrical body of the shock absorber, having a head 1-1 atone end and another head 12 at thev other end, and these heads may be mounted on the body in any suitable or well-known manner as by threading, brazing, welding or the like. From each head leads an outlet passageway 1,3 with which is associated the valve seat 14 for the recept-ion of a valve 15 normally held against its seat bythe spring 16, one end of which rests against the valve 15 as the movable element and the other end against a cap 17 as the stationary element. The cap 17 is provided with an aperture 18 for the passageway of air and is threaded or otherwise suitably adjustably mounted upon the valve casing 19, whereby the tension ofy the spring may be varied, and it is to be understood th`at the cap may be held in-its adjusted position after the spring has been properly tensioned.
VVithinthe body ot the device is slidably mounted a piston 20 which divides the interior of said body into two chambers 21 and 22, and said piston has' a piston rod v23 connected therewithv passing through one of the heads of the shock absorber, and this head is provided with va stulng box 24 to hold a suitable packing 25 compressed by the gland 26.
On both faces of the piston are mounted the cup washers 27 which are held in place by themetal washers 28, the latter being secured by the nuts 29 on the piston rod. A
-pairo-f air passageways 30 are provided in bracket 36V fastened to a vehicle spring 37 by means of. suitable U bolts 38 or their equivalent, it being understood thatv a. portion of the bracket extends beyond the sides of the spring a sufiicient distance to accommodate the nuts 39 having'v threaded 'connection with the piston rod. To connect the shock absorber with the body of the vehicle; the head 11 has a short rod 40 mounted thereon and, if found desirable, said head may be provided with an internally Vthreaded socket 4l to receive said short rod, which, in the case of the forward shock absorber, passes through a portion` of the bracket arm 4l, as shown in Figure l, and has suitable nuts 42 threaded thereon to engage the bracket arm. l"Vhile in the case of the rear shock'absorber, as illustrated in Figure 2, a short rod 40 passes through a bracket. plate 43 which extendsfrom the side of the frame or chassis,A and it is to `be understood that the bracket arm 41a is also secured to the side rail of the chassis.
In most cases the construction'above described and the method of mounting the shock absorbers is the preferred one, but under some conditions, it is advisable to make a less rigid connection between the several parts, and to this end I may provide a ball and socket joint or other. equivalent connection, but for convenience of illustra- OU, Ihm@ ShOWIlefgSOCletAfc as connected with the shock absorber', either to the piston rod 23 or the short rod 40, while the ball 45 is provided with a shank 46 by which it may be attached to any one of the brackets above mentioned. Such an arrangement will permit the usual swinging of the body rof the automobile relative to the chassis.v
`In actual practice, it has been found that when the springs of the several valves have been properly tensioned, the movement of the body downward will be slow and easy,
' while the rebound may be slightly faster, but
any movement `of the body upward beyond its normal position will be quickly checked so that said body during a majority of the time is in its natural position. When the shock absorber is working the movements of the piston cause the air in one chamber to flow through a passageway in the piston to the other chamber, and .in case of some eXtra large obstruction in the roadway, the piston moves a greater distance than ordinarily so that the air in the chamber becomes quickly compressed, the excess air may be expelled through one of the outlet valves at an end of the shock absorber.
If it is found desirable that the air in the shock absorber should be replenished, this may be accomplished. automatically by plac-A ing another valve casing 47 at each end of .the device and associated with an air inlet passageway 48 in which case the valve 49 engages a seat 50 about the inlet 5l in the cap 52 and said valve is held against its seat maintain the prqper pressure in the shock absorber.
Of course I 'do' not wish to be limited to the exact details of construction as herein shown as these may be varied Within the limits of the appended claims without departing from the spirit of my invention.
Having thus fully described my invention, what I' claim as new and useful is l. A shock absorber including a cylindrical receptacle closed at both ends, outlet passageways leading through the closed ends, springvactuated valves controlling said passageway/s, Aa piston slidably mounted within the receptacle and having air passageways therethrough, a spring actuated valve controlling each passageway, the valve of one passageway being opposed tothe other, and a piston vrod attached to the piston and passing through one of the closed ends of the receptacle. p
