FRAME FOR MOTOR-CYCLES.

Specification of Letters Patent.

Patented Mar. 18, 1913.

Application led September 13, 1912. Serial No. 720,302.

To all whom t may concern Be it known that I, ARTHUR H. BILSTEN, a citizen of the United States, residing at VOrt-hington, in the county of Nobles, State of Minnesota, have invented certain new and useful Improvements in Frames for Motor-Cycles; and I-do hereby declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention is directed to improvements in frames of motor-cycles or the like, and has for its object to provide the rear fork thereof with a spring connection for lessening joltings or jars during the travel of the machine.

With these and other objects in view, this invention resides inthe novel features of construction, formation, combinations and arrangements of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawing, in which Figure 1 is a side elevation of the rear portion of a motorcycle frame, showing the same equipped with the spring connection. Fig. 2 is a longitudinal sectional view through one of the arms of the rear fork. Fig. 3 is a sectional view on line 3 3 of Fig. 2. Fig. 4 is a similar view on line 4-4 of Fig. 2.

Referring to the drawing the numeral 1 designates the rear portion of a motorcycle frame, the same consisting of the usual seat mast 2, to the upper end of which is secured the upper end of the rear fork 3, the arms 4 of which are formed from tubular metal. Secured to the lower end of the seat mast 2 are the forked arms 5 to the outer ends of which are pivotally connected the sections G, the purpose of which will appear later. The arms 4 are threaded interiorly at their lower ends for engagement by the sleeves 7. Passing through the sleeve 7 and within the arms 4 are rods S, the upper ends of which are provided with disks 9 which are engaged upon their under surfaces by the upper ends of the coil springs 10, the lower ends of which rest upon the upper ends of the sleeves 7 said springs encircling that portion of the rod which reciprocates in the arms 4. Surrounding the lower ends of the rods 8 are coil springs 11, the lower ends of which rest upon a ianged disk 12 secured to the rods 8 and near the lower ends thereof, the upper ends of said springs bearing against the bottom of the sleeve 7.

The eXtreme lower ends of the rods 8 project slightly below the disks 12 and are pivotally connected to the outer ends of the sections 6 so that when the machine is traveling over rough or uneven ground the jar and jolting incident thereto will be lessened or relieved by the springs 10 and 11, the springs 11 serving to cushion the shock upon upward movement of the rods 8 and the springs 10 the downward movement thereof.

1. In combination, a cycle frame having forked tubular rear arms having their upper ends connected to the seat mast of the frame, forked arms secured to the lower end of the mast, sections pivotally connected to the outer ends of the last named arms, rodsslidably engaging the tubular arms and having their lower ends pivotally connected to the outer ends of said sections, and means for yieldably holding the rods connected to the tubular arms.

2. In combination, a motorcycle frame comprising a seat mast, forkedv tubular arms connected at their upper ends to the vseat mast, sleeves secured in the lower ends of said arms, forked arms having their inner ends secured to the lower end of the seat mast, sections pivotally connected to the outer ends of the last named arms, rods slid ably mounted in the tubular arms, said rodshaving their lower ends pivotally connected to the outer ends of lsaid sections, disks secured to the upper ends of the rods, coil springs surrrounding the upper ends of the rods and having their upper ends engaging said disks and their lower ends the sleeves, similar springs surrounding the lower ends of said rods and having their upper ends bearing against the lower ends of said sleeves and their lower ends resting upon disks secured near the lower ends of said rods.

In testimony whereof, I afix my signature, in presence of two witnesses.

ARTHUR H. BILSTEN. Witnesses: l
