To all whom it mag/concern.- p

Be it known that I,-GUsTAv DIEZEMANN,

` of West Hoboken, Hudson county, in the State of New Jersey, have invented certain cient,r and thoroughly reliable apparatusy which may be easily applied to a vehicle intermediate its body portion and springs and -I so regulated in` relation to the weight of the vehicle in order that the shock produced When the Wheels encounter an obstruction or denressionlin the road and the consequent tion will be entire y overcome, theaction of the car over the road rendered smooth and free from all sudden jolt or undue vibration,

` and, nally, the tractive power of the wheel and the speed of thecar materially increased.

To the attainment of these ends my inven# tion consists in the novel details of construction and in the combination, connection, and

arran ement of parts hereinafter more fully descri ed, and then pointed outin the claims.

In the accompanying drawings, wherein like numerals ofreference indicate like parts, Figure 1 is a side view of a portion of a vehicle-.body and a lspring with a suspension device constructed according to and embodying my invention applied thereto. Fig. 2 is an enfarged detail side view of the suspension device, showing the same attached to the body and spring; and Fig. Sis a section taken on the line 3 3 of Fig. .2.

In said'drawings, 1() designates the apparatus, comprising a support or plate 11, having an angular projection 12, extending upwardly therefrom at a point near its center,

whereby the apparatus may be secured to 'the frame of the vehicle.

13 13' d enote hollow integral cylindrical casings or barrels, whose open ends are pro-v vided upon their lnner surfaces with screwthreads and their closed opposing ends provided vwith centrally-located apertures 14,

15 denotes a shaft extending through the v apertures 14 in the ends of the casings or barrels 13 13' and having its end located within the barrel 13', provided with an integral-iiat lhead. 16, corresponding in diameter substantially with that of the interior of the barrel 13', While the opposite end of said lower end of the link 30. The said bearing shaft 15 is provided with a transverse.

rectangular slot

17, and 18 denotes a removable head having a central openin 19 therein, corresponding in diameter wit that of the shaft 15, and a pin 20, extending throu hsaid removable head and the opening 19 t erein and adapted to be received by theslot 17 when said removable head is adjusted in position upon the end of said shaft 15. A

21 21` denote caps provided .upon their edges with screw-threads adapted to enga e those upon? the inner surfaces of the barre s 13 13', and 22 22 circular recesses provided in the outer surfaces of said caps'21 21 ada ted to receive the ends of a spanner or otfier instrument,wherebvsaid caps 2 1 21 maybe se- I cured and'adjusted inthe ends of said barrels. rebounding of the arts to their normal posi-V 23 23 denote annular packings, preferably made of hard fiber, which are disposed upon"v 7e l the shaft 15 intermediate` the -heads 16 1 8 and the closed ends of the barrels 13 13', andv 24 24 denote fiat circular disks composed of the same material as the annular packings 23 2 3 and'interpose'd between the outersurfaces of the heads 16 18 and the inner-sur -faces of the caps 21 21.

In order to prevent the rotation of the annular packings, the same are provided in their edges Withrecesses 25 and screws 0r pins 26, which extend throughthe barrels 13 13'into said recesses, and* thushold the same duly in position.

27 27 denotel `oil-holes through which a suitable lubricant may be introduced into the barrels 13 13'.' l

28 denotes an armfwhich is keyed to the shaft 15 intermediate the barrels 13 13' by means of a pin 29, and the outer end of said i arm pivotally connected to one end of

alink

30, and 31 denotes a bearing consisting'of a plate 32, having a lateral projection provided with upwardly-projecting ears or lugs 33, in-

termediate of which is plvotally secured the 31. is secured to the upper surface of the` spring 34 near the vehicle-axle by U-bolts or straps35. It is to be noted that-in my improved construction I provide a plurality of frictionbearings, which may be increased by incor-f porating into the structure any number of removable heads, such as 18 47, and the yfrictional engagement of the fixed and removable heads so regulated as to eect the requisite or desired degree of retardation by turning the caps 21 21 more or less, and thereby IOO IIO

increasing or diminishing, as the case may ibe, the degree of frictional contact between the fixed and removable .heads and the fiber packings and the surfaces of the barrels contacting therewith.

It is to be noted that my apparatus is applicable to wheeled vehicles of all descrl tions, and that by its ap lication thereto t e rising and falling of the body upon the axles or running-gear and the consequent compresslon and expansion of the springs will be so retarded as to render the, action of the vehicle smooth and free from all undue jolting or vibration.
