such as is provided for bicycles, motor-p cycles and other vehicles. l
It is a more particular object ot" the invention to provide auxiliary cushioning means interposed between the vertical spring post for the saddle or seat and the under side of said seat and connected with the latter whereby abnormal shocks or jars will be effectively absorbed.
ln one practical embodiment of my present improvements, I provide a laminated leat spring structure extending' longitudinally beneath the seat and connected at its torward end with the vehicle frame, said leat' spring at its rear end having sliding engagement with anti-friction bearing means lixed to the rear end of the seat and intermediate o'f its ends having sliding conne@ tion with the upper end of the spring post for the seat.
lt is another object of my invention to provide means whereby certain oit t-he'leaves or laminations of the cushioning spring may be longitudinally adjusted relative to the others and with respect to the point of connection of said spring with the upper end ot the seat post.
With the above and other objects in view, the invention consists in the improved seat support and in the forni construction and relative arrangement ot' the several. parts thereof as will be hereinafter vmore Yfully de` scribed, illust-rated in the accompanying drawing, and subsequently incorporated in the subjoined claims. Y

Referring in detail to the drawing, 5 designates a portion of the vehicle frame in which the vertically movable spring post 6 Jfor' the support of the seat or saddle is mounted in the usual manner. The saddle seat may be oit' any approved construction and is provided at its rear end with the usual cantle plate 9. The customary wire spring 10 is also arranged beneath the seat Jfor the purpose of longitudinally tensioning tlierlatter and as herein shown is provided with a transverse intermediate portion 11 seated under a curved lip 12. on the forward edge of the cantle plate 9. At opposite ends of said intermediate portion 11, this wire spring is lixed to the cantley plate by suitable bolts 13. Y The spaced side portions of theA spring 10 areforwardly extended from the cantle plate beneath the seat'l, in convergent relation to each other and are suitably connected with a plate 14 fixed to the under sideol the front end or pommel of the seat, as for instance by means of a suitable bolt indicated at l5.
l To the opposite sides ofthe longitudinal bar of the frame 5 the upwardly projecting plates 16 are rigidly lixed by the transverse bolt 17 and between the upper ends of these plates the forward end ot' a longitudinally disposed channel shaped bar 18 is pivotally mounted upon the transverse bolt 19. The rear end of this bar is connected with the forward end of the saddle seat by` the bolt as clearly shown in Fig. 1 of the drawings.
Upon the upper end of the springpost G a horizontally disposed plate 20 having side flanges 21 is rigidly fixed. These flanges adjacent their opposite ends are notched or recessed to receive the ends of the spaced bearing rollers 22., The rollers are retained in said seats by the side walls of a vertical loi;
U-shaped housing 23, said side walls being fixed to the flanges 21 by the screws 24.l The top wall of this housing adjacent its forward end is formed with a pocket or seat 2 5 for an upper bearing roller 26 positioned in the vertical plane of the forward lower bearing roller 22.
Supplementing the sustaining actionV of this auxiliary cushioning spring has its for-I ward end 28 downwardly extended and en.
gaged against the under side of the sleeve on the forward end 'of the spring leaf 2T as shown in Fig. 1 of the drawings. Beneath the leaf 2S the additional spring leaves 30 and 31 respectively are arranged, saidv lower leaf 31 being connected at its rear end with a bolt 32 which connects the ends of a U-shaped clip member 33 embracing the several leaves or laminations ofthe spring structure at a point rearwardly of the bearing housing- 23. It will be noted that the several leaves or laminations of the spring successively decrease in length from the upper toy the lower lamination, and therefore offer successively increasing resistance to vertically applied pressure. For the purpose of Y regulating thisy resistance, I provide the two lower leaves 3,0l and- 31 adjacent their forward endswith suitable notches orV recesses 34 for the purpose of receiving the` bolts 35` connecting theends of two transverse plates 36 extending above and below the series of spring leaves.V The two upperrspring leaves 27 and 28 are provided with a plurality of such notches or recesses 37 intheir opposite edges spaced longitudinally from each other. Thus, it will be apparent that by shifting the two lower leaves 30 and 31of the spring longitudinally witlr respect MVto the two upper leaves and engaging the bolt-S735 in selected recessesor notches 37 of the latter leaves, the rear end portions of the lower leaves 30 andV 31 may be adjustably...positioned with relation to the bearing rollers 22 and 26 inountedyon the upper end of the spring post G to thereby increase or decrease the resistance oifered by the rear end portion of the laminatedspringstructure to verti cally applied pressure.
To the under side of the cantle plate 9 a plate 3S is fixed at its rear end, the Aforward end of said plate having a Ytransverse seat 35) formed therein for a bearing roller 40.
rearend to the eantle plate and openl at its forward end. As clearly shown in Fig. 1 of the drawings, the rear end of the upper leaf 27 of the laminated spring structure extends longitudinally into this housing between the bearing roller Ll0 and the bottom .wall of the housing and exerts an upward bearing pressure against the under side of said roller.
ln the operation of the device above described, it will be apparent that the vxeig t of the rider on the seat 3 4is normally tained by the spring post t3, there being` little ilexure of the longitudinally cxtcndi gj lainii `Led spring structure from its neri dition. -ll'hen, however, the wheelsA of the vehicle encounter' obstructions or ruis in the road surface,resulting in an :abnormal sho/.li or jar to the vehicle frame, such sliorl: will be cushioned by the longitudinally filcuding auxiliary leaf spring, said ,spring at its forward end turning about the bolt il and flexing at its 'rear end as the bearing roller al) moves downwardly on the upward-` ly curved end of the spring lamination 27. In this abnormal vertical movement of the seat relative to the vehicle frame, the intermediate portion of the laminated spring will shift longitudinally relative to the upper end of the springpost (3 between the bearing rollers 22 and ll. Thus, it will be apparent that in this manner such shocks or jars will not be transmitted-to the body of the .rider but will be effectively absorbed by the longitudinally extending laminated spring interposed between the seat and the supporting post G therefor. Bj adjusting the lower spring leaves in the manner above explained, the,responsiveness of the laminated spring structure may be properly regulated in accordance with the weight of l the rider.
In Figs. 6 to 9 inclusive, I have illustrated an alternative means for yieldably connecting the rear end of the longitudinally extendingk spring with the seat. ln this construct-ion l provide a transversely positioned multi-ply leaf spring indicated at i2, the central leaf of which is extended beyend the ends of the upper and lower leaves and pivotally connected by the shackles -ri3 with the depending members #iai which are pivotally rsuspended from the transverse pins or bolts t5 in the rear ends of plates 4 6 which clamp the wire spring 10 to the under side of the cantle plate 9.
The transversely disposed leaf spring ft2 at its center extends over and upon the rear end of the uppermost leaf of the longitudinally positioned spring which is mount edupon the seat vpost in the manner above described, and is rigidly fixed thereto by means of the bolt 4:7. It will be apparent from this construction that the transverse spring 42 connecting therear end of the longitudinall spring with the seat provides loo lltl
