Definitions

  • rlhis invention relates generally to shockl absorbers for automobiles, the invention having more particular-reference to a shock absorber utilizing air compression'.
  • T he invention has 'for an object the provi- ⁇ sion of a novel and improved shock absorber of the piston and plunger type which operates by air compression, a furtherobjectof the invention relating to the increase of general cushioning eiiect by the use of a plurality of cylinders that telescopeone into the other.
  • Fig. 1 of the drawing is a central vertical sectional view of my improved shock absorber.
  • Fig. 2 is a transverse sectional view thereof taken on the line 2-2 of Fig. l.
  • the reference numerals 10, 11 and 12 designate three cylinders which are closed at the bottom by the bottom members 10', 11 and 12 respectively.
  • rEhese cylinders are open at their upper ends, thetop cylinders 10 fitting intor and forming a plunger in the intermediate cylinder 11, while the latter lits 'into the upper end of the lower cylinder 12 and forms a plunger in the latten Fitting slidably in i the top cylinder 10 is a plunger 14.
  • This plunger 14 is formed on its upper end with an upwardly projecting ear 15, while the cylinder 12 has formed on the bottom thereof a downwardly projecting ear 164 these ears 15 and 16 forming the medium of attachment of the device to the body and aXle of the automobile, Vand being here shown as provided with apertures 17 to receive fastening pins or bolts. It will be understood'of course that any suitable provision maybe made for att-aching the plunger le and the cylinder 12 to the proper automobile parts.
  • the plunger 14, and cylinders 10 and 1,1 have their upper halves of diminished di- 1924. Serial y No. 725,411.
  • a tube 25 Fixed at its lower end to the bottom 12 of the lower cylinder 12 is a tube 25 that extends upwardly through the bottomsof the other cylinders 10 and 11.
  • This tube is surrounded ⁇ by an exterior sleeve 26 which is of approximately the same length as the tube and which lits 'snugly in the apertures provided in the bottomsof the cylinders 110 and 1l.
  • the tube 25 andwsleeve 26 are formed with rows of registering apertures 27 and n 28 that are placed throughout the length of said sleeve and tube, these apertures constituting' ports through which air passes into and out of the cylinders 1O,11,and.12.
  • the tube sleeve 26 At its upper end, the tube sleeve 26'fits frictionally in a bushing 29 -itted into the lower end, of a longitudinal passage 8O inthe plunger 114, this Ypassage accommodating the tube and sleeve when the parts move in a collapsing direction.
  • Fixed ⁇ at its ends to the sleeve 26 is a pin 31 that passes through short lonapertures 28 and 27 in the sleeve and tube are 1n registry with one another'.
  • I may vary the degree of air compression resulting in each cylinder as the downward movement of the parts occurs, which may be effected byslightly varying the positions of the openings in the lower parts oi the sleeve so that the latter do not move entirely out of registry with the openings in the tube at any time.
  • a shock absorber including a cylinder
  • a plunger operable to vary atmosphericpresi sure therein
  • a valve device including an apertured tube secured at oneendV 'toi saidl cylinder andi communicating with the yatmosphere, and an apertuiied sleeve movable with said plunger longitudinally of said tube to bring the'y apertures', ⁇ in the sleeve into and outr of registry with those in said tube to open and shut oiii" comnmnicatio'n between said cylinder and the; atmosphere.
  • a shock absorber including a cylinder, a plunger'operable to vary atmospheric piressure therein, and a valve device including a tube and a'sleeve each havingapertures, one
  • a shock absorber for automobiles comprising a cylinder ⁇ a.. tube fixed at its lower end in the bottom of saidcylinder and communicating with the atmosphere, a plunger, a sleeve surrounding said tube, said sleeve being' rictionally engaged with said plung er, and (3o-operating means on said sleeve andtube arranged to permit of limited sliding movement of the sleeve on the tube, said sleeve andtube having apertures therein adapted to bemovedinto and out of registry by sliding movement of the sleeve on the tube.
  • a shock absorber for automobiles comprising a plurality of vertically disposed cylinders itting; tele'scopieally intoY one another, a plunger'itting into theltop cylinder, a tube fixed at its lower end in the bottom of thelow'er cylinder, a sleeve-'surrounding Vsaidtube,fsaid sleeve and tube ex-vr tending upward through the bottoms ofthe upper cylinders, said sleeve being rictionally engaged at' itsv upper end with the said plunger, a pin fixed in said sleeve and passingthrough short' verticalY slots inthe said tube to limit sliding movement of the sleeve on the tube, said sleevel and tube having rows of apertures spaced substantially throughout thelength thereof, said apertures being adapted to be moved into and out of registry with one'anoth'erby sliding movement of the sleeve on the tube.
