Application April 22,

7 Claims.

This invention relates to saddles of the type adapted to be used for bicycles, motorcycles, velocipedes and the like and more particularly to a saddle of the spring supported type.

Our invention relates to improvements in saddles of the type of that disclosed in United States Letters Patent to David S. Troxel, No. 1,022,447, patented April 9, 1912, wherein movements of the saddle, in use, in both upward and downward directions, are cooperatively resiliently resisted by spring sections alternatively acting as compression and tension springs.

While the saddle of the above type is still in popular wide-spread use, in the interests of compactness of construction, better appearance, and the elimination of the downwardly projecting clothing-catching spring and spring securing ends, other saddles having but a single spring action, have also been more recently in demand even though the same riding comfort is not achieved.

An object of the present invention, therefore, is to provide an improved cycle saddle of the double-action tension-compression spring type,

wherein the present day aesthetic objections to saddles of the type disclosed in the said Troxel patent, are absent.

Another object of our invention is to provide a double-action spring supporting structure for a cycle saddle which will be more presentable in appearance than those previously proposed.

Another object of our invention is to provide an improved saddle of the double-action supporting spring type which will be more efficient in operation than prior saddles with which we are at '4 present familiar.

Other objects of our invention and the invention itself will become more apparent by reference to the accompanying drawings of an embodiment of our invention, and from reference to the following description of the said embodiment, wherein reference is made to the said drawings, and in which drawings:

and

Fig. 7 is a fragmentary detail view, showing the connection between the link means and the springs.

Referring now to the drawings, the saddle seat is illustrated generally at l and comprises a padded saddle covering 2 of any desired construction, and a metallic seat frame, suitably formed to constitute the lower surface of the seat and to which the padded covering 2 is suitably aiiixed, in any desired manner.

At 4 there is shown a saddle clamp of any well known type for securely clamping the cycle saddle onto the top of a saddle post, and in the type shown, the clamp 4 is adapted to clamp the saddle onto the horizontal forwardly directed arm of an inverted substantially L shaped saddle post, the lower depending arm of which is preferably rigidly secured to the frame of the cycle.

The clamp t is secured to a pair of parallel members 5' of a preferably sheet metal reach member 5. Secured to the underside of the seat frame 3 is a spring wire 6 bent substantially to V-form and extended adjacent the confluence of the converging lateral arms 6 and 6 to form spring coils 6s, adjacent the pommel portion of the saddle. The spring rails are axially aligned to define a two-section spiral spring, the inner adjacent ends 6-6 being given the form of a loop t o which is interlocked with a tongue 'l-t of a sheet metal element 7 bridging the forward ends of the reach element members 5 and secured thereto in any suitable manner. such as by the riveting or heading-over of the portions 7 projected through openings extending laterally through the forward ends of the said members 5. It is to be understood that other suitable means may be employed for hingingly connecting the forward end of the reach member 5 to the saddle.

The spring wire arms 6' and ii" are fastened to frame 3 in any suitable manner as by projecting the arms through a clip 'IC secured to the under side of the frame adjacent the spring coil t -s and providing eyes on the ends of the arms a and 6" which may be telescoped over laterally spaced bolts 8 secured at the rear of the saddle to frame 3. Bolts 8 also project through the perforated arms of a pair of loop elements 9 and through a perforation provided in a leg of a pair of generally inverted L-shaped brackets It, the loop element, spring arm end, and bracket l9 being secured on bolt 8 by a nut I l.

Each loop element 9 pivotally receives one of a pair of laterally extending arms [2 of a link element or hinge member is which is provided in its lower portion with spaced bearings i l-Id for receiving a pin 15. Encircling pin I5 is one end of a second link or hinge member l6 having the opposite end encircling a pin l'l extending between the parallel members 5 of the reach memher.

A second pair of brackets !8, generally of in verted L-shape are bolted to the frame 3 and a pair of springs l9|9 are supported between the brackets ii) and [8 preferably so that they are suspended below the seat portion. Springs iii are of helical type and or generally conical form hav-- ing their extremities anchored to brackets 99 and If! by bolts l0 and I8 respectively in a generally horizontal position. A pair of link elements 21! are each hooked around pin 15 at one end and at their opposite ends are secured to springs 19 by engaging bolts 2| projecting laterally through eyes We formed at the junction of portions E90 and l9t of the springs and clamped thereto. It will be noted that the portion l9a of each spring is normally under tension or compressed and the portion l9t is normally under compression or expended. Thus, the links 28 are connected be-- tween these two forces of the spring sections which provide a double action oompression-tem sion type of movement. Both springs I9 are connected to a generally U-shaped strap 22 engaging bolts 2! to insure that both springs will be equally subjected to tension and compression.

The means for clamping the saddle to the saddle post constitutes no essential part of the present invention and any suitable clamping means may be employed although we preferably employ the clamp means illustrated herein and more fully described in a co-pending application entitled Cycle saddle clamp Serial No. 64,906 filed February 20, 1936.

The parallel members 5' of the reach member are perforated intermediate their ends to receive a headed bolt 23 also projected through a pair of clamp members 24-24 and a generally U-shaped intermediate clamp member 25 whereby the saddle post 26 will be tightly gripped by jaws of member 25 upon tightening of a nut 2? engaging bolt 23 to draw the arms of the member 25 together.

The operation of the saddle will now be described and is best illustrated in Figs. 3 and 6, Fig. 6 being mainly diagrammatic. When the saddle is not under load it will assume the position illustrated in Fig. 3 and in full lines in Fig. 6, it being understood that the parallel reach members 5' are securely clamped to the saddle post and are substantially immovable with respect thereto. Upon the weight of the rider being applied to the saddle and mainly at the rear portion of the saddle the rear portion of the saddle will be forced downwardly whereby link element 13 will assume the position [3' causing pin [5 to move rearwardly substantially horizontally and assume the position i5 and resultantly member IE will assume the position l6 pivoting around pin l1 since the reach member 5 is fixed with respect to the cycle frame and saddle post. Pin i5 will carry link elements 26 rearwardly to the position 2G and also strap 22 to the position 22' thereby compressing spring portion lQ-t and placing spring portion l9c under tension.

It will be noted that the aforementioned movement of the saddle and supporting structure is a combined rearward movement and downward movement or that one pair of springs absorbs both vertical and longitudinal movement. The inter-locking of tongue 'lc at the forward portion of the supporting structure with loop 6- permits both a pivotal movement and a limited longitudinal movement of the spring coil 6s relative to the reach member. Upon continued application of load to the saddle due to road impact and the like transmitted to the cycle frame and saddle post, primarily through the rear wheel of the cycle, the angle between link member i3 and member It will tend to decrease and in-- creased compression will be exerted on portion I9t of the spring and increased tension on portion I 9c of the spring. The reverse will be true if the major portion of the load were concentrated at the pommel portion of the saddle and in this case the portion l9-c will be placed under compression and the portion l9t under tension so that in either event a double action of compression and tension cushioning shock is provided by the springs 19. Also, each of the spring portions [9-0 and I9t exert a snubbing action tending to dampen continued movement of the saddle or to quickly bring the saddle to a stable position Where the spring pressure is equalized in correspondence with the load.

Thus, we have provided a relatively simple sup-- port for cycle saddles wherein a pair of horizontally disposed springs and associated linkage not only provide a saddle of pleasing appearance but are adapted to resiliently absorb both longitudinally and vertically directed movements 01" the saddle relative to the saddle post.

Although we have shown and described a preferred form of our invention, we contemplate that numerous and extensive departures may be made therefrom without departing from the spirit of our invention or the scope of the appended claims.
