United States Patent COIL CLIP CONNECTION FOR CYCLE SADDLE Maurice J. Walsh, Worcester, Mass., assignor of one-half to The Faulhaber Company, Monroeville, Ohio, a corporation of Ohio, and one-half to The Persons-Majestic Manufacturing Company, Worcester, Mass., a corporation of Massachusetts Application January 10, 1957, Serial No. 633,411

Claims. (Cl. 155--5.22)

This invention relates to saddles for bicycles, velocipedes and the like, and more particularly to a new and improved saddle supporting and tensioning means.

The nose coil of a cycle saddle must be adapted to withstand frequent and violent flexing occurring at or near the point of attachment of such coil to the saddle. Such attaching means, therefore, must be adapted to withstand various stresses and strains occurring during the operation of such a cycle, and yet such means should be capable of being produced at a relatively low cost and, at the same time, be capable of quick and easy installation.

Therefore, an object of this invention is to provide an improved connection for the nose coil of a saddle to the base member thereof.

Another object is to provide a simple, easily constructed and readily assembled means for attaching a nose coil to a saddle, which will withstand the frequent flexing occurring at or near the point of attachment.

Other objects of this invention are to provide a saddle construction, adapted to be produced at a relatively low cost, the same being sturdy and reliable in operation and quickly and easily installed.

The foregoing and additional objects and advantages of this invention will appear during the course of the following description of one illustrative embodiment of the invention.

In the accompanying drawings forming a part of the description of this invention:

Fig. 1 is a side elevation view of a bicycle saddle showing a partial section of the nose coil connection;

Fig. 2 is a central, vertical sectional view through the forward portion of the saddle illustrating the means for attaching the nose coil;

Fig. 3 is a partial bottom view of the nose coil showing the cover plate;

Fig. 4 is a partial bottom view of the nose coil connection with the cover plate of Fig. 3 removed;

Fig. 5 is a bottom view of a portion of the saddle, while Fig. 6 is a perspective view of a nose coil ends and the cover plate.

In the drawings, the numeral 10 refers generally to a saddle of the type adapted to be used on bicycles, motorcycles or the like. The same is provided with a pair of spaced rear supporting springs 11 connected to the opposite ends of a transverse bracket 12 secured to the rearward 'end of a reach 13. The reach 13, disclosed in the illustrative embodiment, comprises a single strap of metal bent into a U-shape at its forward end as indicated at 14 and provided with spaced rearwardly extending portions 15 and 16. An angularly adjustable clamp 17, positioned between the spaced reach portions 15 and 16, is formed with serrated surfaces engaging serrated clamp plates 18. A bolt 19 extends through spaced reach portions 15 and 16 clamp 17 and clamp plates 18 in such manner that, when the bolt 19 is tightened the reach portions 15 and 16 are pressed toward each other thereby compressing the clamp 17 so that it grips a saddle post 20.

The seat portion of the saddle 10 comprises a pair of similarly shaped metal base plates 21 and 22, and a by tongues-26 struck from the plate 21 passed through aperture 27 in the plate 22 and bent firmly against the under surface of the plate 22. One of the tongues 26 preferably is located near the front of the seat in order to cooperate with the attaching means for the nose coil.

The nose coil 28 consists of a single piece of suitable wire doubled upon itself at its center, as indicated at 29. The doubled portion 29 of the wire is formed into a loop 30. Straight wire portions 31 and 32 extending from the loop 30 are wound into spring coils 33 and 34 and then bent to form straight spaced parallel end portions 35 and 36 terminating in short inwardly extending ends 37 and 38 bent sharply substantially at right angles to the parallel end portions 35 and 36. The forward U-shaped 1 end 14 of the reach 13 is formed with a notch indicated at 39 while a bolt 40 extends through the two reach members 15 and 16 a short distance rearwardly of the notch 39, the bolt 40 passing through the loop 30 formed at the doubled end of the nose coil wire, and when tightened pivotally secures the loop 30 of the nose coil to the reach- 4 13. The straight portions 31 and 32 between the loop 30 into spring coils 33 and 34 pass through the notch 39 and engage the upper edge 41 of the notch 39 when the saddle is completely assembled.

The base plate 21 is formed with a depressed port-ion 42 extending into an opening 43 into the lower base plate 22 for securing the nose coil to the base plate 21. The

depressed portion 42 of the, base plate 21 is provided centrally with a square opening fitting the square shoulder of a carriage bolt 44. The cover plate 45 is formed with an aperture 46 receiving the bolt 44 and is also provided with side flanges 47 adapted to engage the under surface and on opposite sides of the in-turned tongue 26 struckfrom the base plate 21 and positioned rearwardly of the bolt 44.

A nut 50, screwed on the bolt 44 serves to press the cover plate 45 tightly against the under surface of the straight portions 35 and 36 of the nose coil, and in turn, to press the upper surface of the straight portions 35 and 36 against the under side of the base plate 22 with the, down-turned ends 37 and 38 extending through the holes 48 and 49 respectively. Be means of the foregoing construction, whenever the cover plate 45 is assembled over the straight wire portions 35 and 36 and the bolt 44 andthe nut 50 are tightened, the wire portions 35 and 36 are firmly secured in position and thereby are prevented from escaping from their attachment, by movement in any direction.

in any event are of less depth than the thickness of the wire portions 35 and 36 plus the height of the end por tions 37 and 38, so that when the cover plate 45 is secured in position, the wire end portions 37 and 38 cannot escape from the holes 48 and 49.

It will be understood by those skilled in the art that the nose coil may be formed from spring steel wire, which is first wound and bent into the desired shape and then given a spring tempered by conventional treatment. In the embodiment herein disclosed the nose coil is initially formed with the straight portions 31 and 32 separated Preferably the flanges 47 are of less depth, than the thickness of the wire portions 35 and 36, butfrom straight portions 35 and 36 through a greater angle than that which the parts assume in assembled relation, so that it is necessary to tension the coils 33 and 34 by bending the opposite ends toward each other to assemble the nose coil in position. After the parts are assembled, unwinding of the coils to relieve the initial tension by upward movement of the straight portions 35 and 36, is prevented by the long bearing surfaces of these straight portions 35 and 36 against the under side of the base plate 22. Similarly, unwinding by downward movement of the straight portions 31 and 32 is prevented by the engagement of the loop 30 around bolt 40 and the engagement of the straight portions 31 and 32 with the edge 41 of the notch 39. At the same time, the nose coil is free to yield to provide a resilient support of a part of the weight of the rider on the seat, since the front end of the seat and the coils 33 and 34 may move downwardly With the loop 30 pivoting around the bolt 40, accompanied by further winding up of the coils 33 and 34 to provide increasing spring force with increased movement. Also in the present embodiment of my invention, straight end portions 35 and 36 are initially tensioned to lie substantially parallel to each other slightly closer together than the holes 48 and 49. The tongue 26 is arranged to enter between and spread the ends of the wires 35 and 36 to the exact spacing of the holes 48 and 49 for facilitating assembly.

While a preferred embodiment of the invention has been described in considerable detail, it will be understood that various modifications and rearrangements of the parts may be resorted to without departing from the scope of the invention as defined in the following claims.
