ATTORNEYS novelty will be apparent from Patented Feb. 11 193$ UNITED STATES PATENT GFFICE Application July 13, 1933, Serial No.

Renewed July' 1, 1935 9 Claims. (Cl. 208) My invention relates adapted to be used for velocipedes, and the like, and particularly to a saddle which is supported at the rear end by a pair of springs, one on each side, each spring including a tension portion and a compression portion with both portions of each spring arranged to support the load imposed on the saddle.

It is an object of the invention to: provide a saddle of the type referred to of improved construction, aifo'rding a high degree of comfort in use.

Another object of the invention is to provide a saddle whichwill be simple in construction, inexpensive to manufacture, and which is efficient in operation.

A further object of the invention is to provide an improved saddle employing a minimum of parts which are capable of being very inexpensively fabricated.

Another object is to provide improved means for connecting the spring or springs with the reach bar.

Other objects of the invention and features of the following dewith the accompato saddles of the type bicycles, motor-cycles,

scription taken in connection nying drawings, in which:

Fig. 1 is a bottom plan view of one form of improved saddle provided by my invention;

Fig. 2 is a longitudinal medial sectional view of the saddle shown in Fig. 1;

Fig. 3 is a sectional view taken substantially along the plane 3-3 of Fig. 1;

Fig. 4 is a sectional view taken substantially from the plane 44 of Fig. 2;

Fig. 5 is a fragmentary rear elevational view of another embodiment of my invention;

Figs. 6, '7, and 8 are views similar to Fig. .5, but with the seat element removed, and showing other embodiments of my invention; and

Fig. 9 is a sectional view taken from the plane 9-9 of Fig. 8.

Referring to the drawings, I have shown in detail a preferred form and several modifications of the saddle construction provided by my invention.

In the drawings I have illustrated at I the saddle seat element, the construction of which constitutes no essential part of my invention which may, according to the well known practice, comprise a sheet metal frame 2, an inner or bottom cover 3 of leather, cloth, or the like, an outer cover 4 of leather or the like, and suitable filling material 5.

A U-shaped yoke 6 having the closed end thereof disposedadjacent the frame 2 and extending transversely thereof,is hingedly or pivotally connected to the frame by clips 7, or by other suitable means. The legs of the yoke 6 depend from the frame as at 8, and extend axially through aligned springs 9. As shown in Figs. 2 and 3 of the drawings, each of the springs 9 comprises an upper portion In and a lower portion II, the upper portion being an open wound conical spring and the lower portion being a more closely wound helical spring. The lowermost portions of the springs are tightly wound, as at l2, .and grip the ends of the members 8. It will be seen that the springs 9 are each constructed of a single continuous length of resilient flexible material and have two portions, a. tension portion and a compression portion.

As shown in the drawings, there is a forwardly and rearwardly extending reach member indicated generaly by the reference character l5, which may be constructed in any desired manner and which, as shown in the drawings, comprises a pair of generally parallel arms [6 which are joined at their forward ends by a yoke portion I 8.

The forward end of the reach member may be secured to the saddle seat element in any desired manner, and as shown in the drawings, the sheet metal body of the seat element has a portion l9 depressed from the main body and the forward end of the reach member is fitted between the portion I 9 and the body of the seat element. The portion l9 may then be depressed, as at 20, between the arms [6 of the reach member so that the forward end of the reach member can slide slightly relative to the saddle seat when weight is placed on the seat, but cannot pull out from under the portion l9. A saddle post clamp device, indicated generally at 2|, is clamped upon the midportion of the reach element.

The arms of the reach member are bent outwardly adjacent their rear ends and terminate in eyes 22 which are slidably fitted on the rods 8. It will be seen that the rear ends of the arms of the reach member extend between the convolutions of the springs 9, preferably at about the point where the conical portions and helical portions meet.

When weight is placed on the saddle, the upper portions of each of the springs is pushed downwardly and one of the convolutions of the spring engages an arm of the reach member, as at 23, sothat the conical portion of the spring is compressed. This permits the rod 8 to move downwardly, and as the lower end of the spring is rigidly secured to the rod, and as one of the convolutions of the spring is held by the arm of the reach rod, the lower portion of the spring, that is,,

the helical portion, is expanded.

It will be seen that the load on the saddle is supported in two ways; that is, by the tension sp in and by the compression spring. Since the load is supported by two springs, I am enabled to reduce the size of the springs over construcpression springs,

pending rods tute a compression spring,

below the portions of reduced diameter constitute 2 tions where all of the weight is transmitted to the spring in a single manner. By thus making the springs lighter, they may be made more elastic and thus give an easier support to the rider. It will be seen that in the construction provided in this application, while the springs operate both as compression springs and tension springs, they are constructed as a single spring, from a single continuous length or wire. This greatly reduces the cost of manufacture of the springs, and also eliminates the necessity curing the two springs together. It will also be seen that the reach bar is directly interlocked with the springs without the use of bolts, washers or other intermediate parts. V

7 Somewhat different means of connecting the ends of the arms of the reach bar to the springs is illustrated in Figs. 5 to 8 inclusive. As shown in Fig. 5, the ends of the arms 30 of the reach bar are provided with closely bent loops 3| which engage the inner face of one of the] convolutions of the springs 32 adjacent the mid-portion of the springs. In the form shown in Fig. 6, the arms 53 of the reach member extend between the convolutions of the springs 35 and diametrically across the springs, terminating in closed loops 34 which engage the outer portions of one of the convolutions of each of the springs. Each of the arms 33 of the reach bar tion of another convolution of the sp-ring'adj acent the inner edge of the spring, as at 36, so that load on the spring is transmitted to the reach bar at two points adjacent opposite sides of the spring.

It will be seen that in the embodiments of the invention shown in Figs. 5 and 6, the springs 32 and 35 are substantially identical in construction with the springs 9 employed in the saddle illustrated in Figs. 1-3, and are formed of a single continuous length of resilient flexible material, and have two portions, a compression portion located above the end of the arm of the reach member, and a tension portion located below the end of the arm of the reach member.

A still difierent form of the invention is illustrated in Fig. '7, and. as illustrated, each of the springs :28, which are generally similar to those employed in Fig. l, is provided with a small loop or eye ll adjacent the mid-portion. The ends or" the arms 52 of the reach bar are off-set slightly as at ii and extend through the eyes 4 I. The portions of the springs above the eyes are comwhile the portions below the eyes are tension springs. The springs 4ll,'like those illustrated in Figs. 2, 5, and 6, are constructed of asingle continuous length of resilient flexible material.

A still different form or construction embody- 'ing this invention is shown in Fig. 8. As shown in the drawings, the springs50 employed in this form of construction each comprisean upper portion 5!, which is an open wound, generally conical portion, and a lower portion 52, which is'a more closely wound, generally helical portion. Intermediate the conical and helical portions, and connecting the upper portion and the lower portions, are convolutions of greatly reduced diameter, as at 53, which closely surround the de- 54 of the U-shaped member 55. The ends 51 of the. arms 56 of the reach bar extend around the smaller convolutions 53 so as to be in load supporting engagement with these convolutions. The portions 5! of the springs 59, above the portions of reduced diameter constiwhile the portions 52 for any means for se also engages a pertension springs. It will be seen that the spring employed in the form shown in this figure, like the other springs illustrated in this application, is constructed of a single piece of wire.

It will be seen that in each of the embodiments of the invention illustrated and described, a single spring having both tension and compression portions is employed. It will further be seen that the reach bar has load supporting connection with the springs intermediate the ends of the springs and that weight on the saddle is transmitted {to the reach-bar through opposite ends of the springs; that is, by compressing the upper portions of the springs between the seat element and the reach bar, and by extending the lower portions of the springs when the lower 'e'n'd'sof the depending rods to which the springs are se cured, move downwardly away'from the ends 01 the reach bar. 7 r s It 'will'also be seen'that in" each of the embodiments of the invention illustrated and described herennthat the lo'adsupportingmeans, that is, the reach bar, is directly interlocked with the springwithout the use of bolts, or cla'mping or special securing means of any kind.

The saddle construction provided by tliis 'application affords a high degree of comfort in use, and is simple in construction, is inexpensive to manufacture, and employs *a of which are capable of being easily fabricated.

While a preferred form ofthe invention and several modifications have illustrated in detail, it should be understood'that many changes and modifications may *be made within the scope and spirit of my inventionavithout sacrificing its advantages.
