Specification of Letters Patent.

Patented Au 27,1912.

Application filed October 1'9, 1911. Serial no. 655,557.

To all whom it may concern Be it knownthat I, GUSTAV KANTER, a subject of the Emperor of Germany and King of Prussia, and a resident of Hamilton street, in the post-town of Murtoa, in the county of Borung, State of Victoria, Coinmonwealt-h of Australia, have invented certain-new and useful Improvements in or Relating to Pneumatic Shock-Absorbers for Vehicles, of which the following is a specification. 2

This invention relates to pneumatic shock absorbing devices interposed between the ve hicle body and the wheels thereof and preventing the conveyance of road or other shocks from the wheels to the said body.

The object of the invention-is to provide a device particularly for use in con unction with an automatic pneumatic vehicle wheel,

such as that disclosed in concurrent application tor patent filed prior hereto :by the presentapplicant. By the invention astorage reservoir 1s provided for surplus air pumped by the vehicle wheels which air when excessive in the reservoir may be led therefrom and utilized for any other purposes desired- -But in order that this in vention may be better understood reference will now be made to the accompanying sheet. of drawings which is to betalien as part of this specification and read herewith z- Figure 1 is a sectional view of this invention receiving air through a dead or fixed axle. Fig. 2 is a sectional view of this inventlon receivlng air through a l1ve or revoluble axle. Fig. 31s a view of a collapse preventer.

=4: and amp leather 38. above the baseplate is an inner collar 5' This invention includes a'casinghaving a base plate 2 upstanding above whichis anouter collar 3 provided with piston rings Also upstanding havingair outlet passages .6 formed therein,

each controlled by a non-return valve 7. VVithi'n the inner collar 5 is a minor cover 8 provided wit-h piston rings 9 and a cup leather 391and also having in its top a depression or saucer 10. Upstanding from the-minor cover S are a plurality of studs l0 around each of which is a minor cushioning spring 41. Around the outer collar 3 is a major cover 11 having at or near" its top apivot pin 12 mounted lug .13. At the topof the major cover 11 is a lubricating cup 14 from which passes a minor vertical lubricating passage 15. A lubricant drips within the inner chamber.

from this assa 'e into the saucer 10. Also Formed by the outer collar 3 and the 0 major cover 11 between the inner collar' 5 and the mmor cover 8 is an outer chamber.

Formed in the outer collar 3 are oulet passages 44 each controlled by a non-return valve 45. with the outer chamber. Formed by the inner collar 5 and minor cover 8, and within the same is an. inner chamber. Upstanding within the inner chamber is a pillar 42 on the top of which reposes a non-return inlet vhlve 17. This controls a. delivery port 18 in the said pillar. Communicating with the delivery port IS, when (Fig. 1) a dead axle such as 19 is used, is an axle delivery port 20. Supported by the pillar 42 is also a major cushioning spring 43. Any number of pillars and springs 43 may be used.

When a live axle (Fig. 2) such as 21 is used a collar 22 is provided thereon. Around said axle in the said collar is formed an annular groove 23 with whichcommunicate subsidiary radial ports 24. These communicate with .a major delivery port 25in the axle. Then a live axle is used there is also provided upon the outer collar 3 a subsidiary collar 28 provided with an annular groove lonnnunicat-ing with the groove 26 is a delivery port 27 which conveys air from the groove to the delivery port in the pillar In addition to the foregoing with motor or like vehicles there may be pivoted to any suitable part of the vehicle by a pivot pin 29, a lever 80 locked in any desired position The said passages communicate in any well known way. Should four absci-hers be used, two above the front axle and two above the back axle of a vehicle, (although any number may be used) the said lever 30 may be pivoted in close proximity to the drivers seat. A lever 31 is then pivoted by a pivot pin 32. to any suitable part of the vehicle near the rear thereof. Connecting the levers 30 and 31 is a link 33 having near its front end a depending portion'3 l'from which projects a finger 35.

'Protruding from the lower end of the lever 31 is an elbow 36 having a foot 37. Upon a vehicle stopping the driver by the'lever 80 causes the finger 85 to en age the front axle of the vehicle or a protu erance 46 project- 110 lug therefrom while the elbow 36 engages the rear axle or a protuberance 47 projecting 3 escapes by the non-return valves 45. This cranked and provided with, a depending portion and finger. Upon the driver wish- 5 mg to start the vehicle the lever 30 is again operated disengaging the finger 35- and elbow 36, which permits the vehicle body and the major cover or covers 11 to descend forcing air from the outer chamber. This air may be utilized to start the engine.

I With this invention the vehicle body may be supported'by the pin 12 and air is admitted to'the absorber from the axle whether it be a live axle or a dead axle, into the inner chamber. Upon a predetermined pressure being reached air escapes from the inner chamber into the outer chamber. case the covers 8 and 11 are elevated to a greater or lesser extent. 'Upon a shock bemg communicatedto the absorber the covers rise or fall around the inner and outer collars 3 and 5. When a predetermined pressure is reached in the outer chamber either through an over suppl or byreason of the rising and falling oft e outer cover 11, air

air may e directed where and as desired and used for any purpose, Itmay be heated and expanded, used for ower, assimilated I 3 0 with Oll, spirits or -the li e and used as an aj lluminative, or be utilized in other ways such as for sounding an alarm signal.

.' .JWhile the inner chamber is belng' filledwith air theminor cover rests upon the majo'r cushioningspring s and the major cover upon the minor cushioning springs.

Having now described my invention, what I claim as new antkdesire to secure by Letters Patent is:

1. In; improvements in or relating to pneumatic shock absorbers {or vehicles, a casing consisting of'an outer collar and an inner collar, a mlnor-cover moving vertically in relation. to the said inner collar and a major cover moving vertically in relation to theouter' collar, sald minor and major .cov-' ers being relatively movable.

5. In improvements in or relating to pneumatic shock absorbers for vehicles, an axle having a port, radial ports communieating-with saidport, a collar on the axle having an annular groove communicating with the radial portiif'ani outer chamber" above said axle, a co lar, an inner chamber within said outer chamber, a port communicating with the an nul'ar groove of the outer chamber collar and the-said inner chamber. r
