TANDEM ATTACHMENT FOR MOTOR-CYCLES.
Specification of Letters IPatent.
Patented Dec. 19, 1916.
Application filed July 15, 1915. Serial No. 40,084.
To all whom. it may concern:
Be .itknown that I, CLARK Summon, a citizen of the United States, and resident of Huntington Beach, in the county of Orange and State of California, have invented certain new and useful Improvements in Tandem Attachments 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.
My invention relates to a tandem attachment for motor cycles, and more particularly to that type of attachment wherein the weight carried thereby is supported on leaf springs.
Many attachments of this sort are on the market at the present day. However, most of these are of com licated construction reuiring frequent a justment and affording little comfort to the user. Therefore, one feature of my invention resides in the provision of a simple and efficient tandem attachment requiring practically no adjustments and constructed in the most improved manner, thereby affording great comfort to the user.
The prime object of my invention lies in the construction of a motor cycle tandem attachment in which curved leaf springs are used to impart resilienc Another object l0Sl( es in making the saddle post members and foot supporting members integral so that both may 0 supported by the same resilient means and therefore move simultaneously.
A still further object resides in the novel manner of mounting the attachment on the means for attaching the entire structure to the frame of a motor cycle.
Other objects and novel features of my invention will be apparent from the following description in connection with the accompanying drawing in which I have illustrated a preferred embodiment of my invention, which I have found in practice to give good results.
Referring to the drawings: Figure 1 is a perspective view of a preferred form of tandem attachment constructed according to my invention. Fig. 2 is a detail plan view illustrating the top of the saddle post members. Fig. 3 is a diagrammatic view Near the showing the position in which the tandem attachment is placed on a motor cycle.
In detail, the tandem attachment as shown in the drawing, comprises the two saddle post members 1 and 2 converging at the top and terminating in a horizontally extending saddle post 3. At the lower ends of saddle post members 1 and 2 are the foot supports 4 and 5, respectively, and preferab y in the form of pedals; and at the upper ends of these members, below the curved or convergin portions, are brackets 5 and 6. ottom of the lower end of each saddle post member, arranged to guide the saddle post members, are brackets 6 and 7, each slotted as at 8 to fit on the axle of the rear wheel of a motor cycle, as shown in Fig. 1. Secured to the brackets 5 and 6, by means of shackles 9 and 10, respectively, are the upper ends of the curved leaf springs 11 and 12, which have their lower ends seated on brackets 6 and 7 and held in place by bolts 13. The brackets 6 and 7 are provided with lubricators 14 to grease the saddle post members 1 and 2.
Attaching members 15 are secured to the frame of the motor cycle by clamps bolted through holes 16 therein and not shown since any suitable clamp of well known form may be adapted for this purpose; and riveted, or otherwise secured to these members are uprights 17 connected at their upper ends by a handle bar 18.
livoted between the upper ends of the attaching members 15 and at the crotch of the conver ing ends of the saddle post members 1 (UK 2, is a supporting bar 19 which serves the purpose of maintaining the saddle post bars in their proper upright position and yet allows them to' reciprocate when shocks are imparted thereto. To hold the lower brackets 6 and 7 in proper relation with respect to the rest of the attachment, strut members 20 are provided which are attached at one end to the attaching members 15 and at the other'end to brackets 6 and 7, respectively. Also, disposed between the shoulders 22 on saddle post members 1 and 2, and brackets 6 and 7 are the coil springs 23 for a purpose to be set forth in explaining the operation of the attachment.
The operation of the attachment is as follows: When the weight of a person is carried by a saddle 24 on the saddle post 3 and on foot supports -1 and 5, the weight is so mrtod on springs 11 and 12 by reason of the iact that the upper ends of these springs are shackled at 9 and 10 to the saddle post members 1 and 2, whereas the lower ends are fixed to brackets 6 and 7 in which the saddle post members are guided for reci nocating movement. Thus it will be seen that when the motor cycle to which the attachment is allixcd. passes over an obstruction in the road. these springs 11 and .12 act to absorb the intensity of the shock or jolt. However, in order that the recoil of springs 11 and 12 may not be too abrupt. thereby causing inconvenience to the occupant of the attachmeni, coil springs 23 are provided. These coil springs have an expanding tension but are compres ed by the recoil of springs 11 and 12, thus absorbing the abruptness of the recoil.
It will be evident from the foregoing description that the attachment herein descri wed and in connection with the accompanying drawing, illustrates one ractical embodiment of my invention; it is nowever to be understood that I do not limit my inrention to the embodiment heroin shown and descrilu except in so far as the appended claim imports.
I claim:
A tandem seat attachment for motor cycles, comprising a bracket for attaching same to the frame of a motor cycle, saddle 0st members pivotally attached to said iiracket at their upper ends, pivoted links attached to said saddle post members adjacent to their upper ends, brackets carried on the rear axle of the motor cycle having sleeves thereon for slida'bly holding the saddle post members adjacent to their lower ends. coil springs carried on said saddle post members beneath the brackets for cushioning same, and bowed 'leaf springs connecting said pivoted links and lower brackets, substantially as described.
In testimony whereof, I have signed this specification in the presence of two subscribing, witnesses.
