BICYCLE-SADDLE SPRING.

Specification of Letters Patent.

Patented March 10, 1908.

To all whom it may concern:

Be it known that I, MILLER M. DEEM, a citizen of the United States, residing at Reading, in the county of Berks and State of Pennsylvania, have invented certain new and useful Im rovements in Bicycle-Saddle Springs, of which the following is a specification.

This invention relates to improvements in bicycle saddle springs, and the object of the present device is to provide an attachment y means of which the strain is removed to a point remote from the bolt which secures the spring to the pommel while still retaining the proper resiliency at the forward end of the saddle. There are several reasons for thus removing the strain. First, it reduces very materially, the chances of breaking the pommel at this, its weakest point, and also that it provides a movement of the forward end of the saddle not heretofore obtained.

Heretofore the forward end of the spring has been secured to .the saddle at the oint where the bolt entered the pommel. Mg object has been to remove the point of connection from this oint, because it is necessarily weakened by t e bolt hole and I have provided an attachment to the spring whereby the forward end of the spring is given a pivotal or movable connection with the saddle the forward end of the saddle is given the roper resiliency and the point of connection between the saddle and spring removed from the point where the bolt enters the pommel, preferably to the rear thereof and nearer thecenter of the saddle. This attachment consists of a plate of metal, capable of being adjustably secured to the pommel and having an eye in its rear end in which the forward end of the truss spring is pivotally secured. The invention is more fully described in the following specification and clearly illustrated in the accompanying drawing, in which Figure 1 is a central longitudinal sectional view of a saddle with my invention applied thereto. Fig. 2 is a plan view of the forward end ofthe spring with the saddle removed.

The numeral 1 designates the saddle and 2 the pommel thereof. The usual rear springs 3 are used and to these I secure the truss spring 4. The forward end of this truss spring is bent to form two loops 5'and is then brought back to a point approximately in line with the center of the saddle. At this point 6 it is engaged, pivotally, by the end of a plate 7. This plate 7 is secured to the under side of the pommel by means of the bolt usually usedfor securing the forward end of the truss spring. This plate consequently forms what may be said to be a part of the pommel, at the same time the connection of the spring to the pommel is removed to the'point 6, considerably to the rear thereof and away from the bolt which holds it to the pommel, where the plate is formed with an eye 8 and in this eye, the end of the spring is pivoted, and this pivotal'connection allows a very considerable movement of the forward end of the saddle, while any jolt or strain to which the pommel is subjected is removed to this point 6.

It will be seen that with this construction of truss spring the forward end of the saddle is allowed considerable room for vertical movement, which has been almost wholly unobtainable where the spring has been secured to the pommel directly at the bolt. In this case it has been necessary to depend on the compression of the forward coil or loop of the truss spring for any resiliency obtained; With my construction the movement is obtained through the spring of the socalled tongue 9 formed by the end of the truss spring in its return from the forward curve, to the point of its pivotal connection to the saddle thus allowing a movement not obtainable where the spring is formed with a complete convolution at the forward end.

Having thus fully described my invention what I claim and desire to secure by Letters Patent is In a bicycle saddle spring, a truss spring M. M. DEEM.
