4 To all whom it may concern:

Be it known that I, HOWARD W. WVEED, a citizen of the United States, and a resident of Stamford, in the county of Fairfield and State of Connecticut, have invented a new and improved Folding Back, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved folding back for motor cycles, bicycles and like machines and deices, and arranged to enable the rider to readily swing the back into approximately horizontal position for mounting and dis mounting purposes, and to permit the rider to swing the back into upright supporting position, after: having mounted, to support the back of the rider while using the machine.

In order to accomplish the desired result use is made of brackets, preferably fixed to the under side of the saddle, a back having side arms mounted to swing on the said brackets to assume a folding or a supporting position, the said side arms having angular slots, arn s mounted to swing'on the brackets and having pins extending-into the said angular slots and handles held on the said arms and adapted to be taken hold of bythe rider to impart a swinging motion to the said arms and to the side arms of the back with a view to swing the latter from a supporting position into a folding position or vice versa.

A practical embodiment of theinvention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference inclicate corresponding parts in all the views.

Figure 1 is a reduced side elevation of the folding back as applied to the saddle of a motor cycle; Fig. 2- is a side elevation of the folding back in supporting position; Fig. 3 is a rear end elevation of the same; and Fig. 42 is an enlarged side elevation of the lower portion of one of the side arms of the folding back to more particularly show the shape of the angular slot.

To the under side of the saddle A are secured rearwardly extending brackets B connected with each other at their terminals by a cross rod C on which are mounted to swing the lower ends of'side arms, carrying at their upper ends a back E for the rider to lean against after being seated on the saddle A and at the time the back E is in Specification of Letters Patent.

supporting position, as shown in Figs. 1, 2 and 3. Each of the side arms D is provided with an upwardly extending slot D terminating in a forwardly and upwardly extending branch slot D as plainly shown in Fig. 4, and the slot in each arm is engaged by a transverse pin F held 011 the free end of an arm G secured to a shaft H journaled in the brackets B a distance in front and somewhat below the connecting rod C previously mentioned. Each arm Gr is provided with a handle I, within reach of the rider when the latter is seated on the saddle A or is in dismounted position. The arms G are so ar ranged relative to the slots D in the side arms I) that the pins F of the said arms G engage the upper ends of the branch slots D of the slots D at the time the side arms D are in upright position with the back E in supporting position. It will be noticed that when the parts are in this position the arms G hold the side arms D against rearward and downward swinging movement owing to the angular position of the arms Gr relative to the connecting rod C which forms the fulcrum for the side arms D. lVhen it is desired to swing the back E into a folded position then the rider takes hold of one of the handles I and swings the same downard so that the shaft H is rocked and with it the arms G to cause the pins F to travel down the branch slots D into the slots D and to then bear against the rear walls of the said slots to swing the side arms D downwardly and rearwardly into the folded position shown in dotted lines in Fig. 1. It will be noticed that when the back E and its side arms D are in this folded horizontal position the rider can readily dismount from the saddle A or remount the saddle as desired, and when the rider has remounted and desires to use the backE for supporting purposes then it is only necessary for the rider to take hold of one of the handles 1 and swing the same upward and forward to cause a like swinging movement of the arms G which by the pins F impart an upward and forward swinging motion to the side arms D to move the back E into upright or supporting position. In order to assist the upward swinging movement of the side arms D use is made of springs J attached at one end to the pins F and at the other end to studs K attached to the side arms D, as plainly indicated in Figs. 2 and 3. It will be noticed that when the side arms D are swung downward and rearward into folded position, the springs J are placed under-"tension, and when the rider swings the handles I upwardly and forwardly, as previously explained, then the spring J assists the upward swinging movement of the side arms D given by the arms G, as previously explained.

It will be noticed that the folding back is wholly in the rear of thesaddle A and the handles I can be readily reached by the rider when mounted on the saddle A to swing the back E into a folded or into a supporting position, as above explained. As the folding back extends in the rear of the saddle A it does not interfere with the riders freedom when mounted on the saddle. a In order to limit the downward and rearward swinging movement of the side arms D, the arms G are provided with recesses G adapted to engage the outer ends of the connecting rod C at the time the side arms D reach a folding position, as indicated in dotted lines in Fig. 1.

The folding back shown and described is very simple and durable in construction and composed of comparatively few parts.

Although I have shown the brackets B as attached to the under side of the saddle A it is evident, that I do not limit myself to this particular manner of placing the folding back in position as the said brackets B.

may be attached to the frame of the machine or any other part of the same.

It will be noticed that when the machine passes over a rough road, the back is not liable to accidentally swing into a folded position owing to the pressure exerted by the springs J on the pins F of the arms Gr, thus holding the pins against downward movement in the slots D. The springs J also serve to draw the pins F into final position in the upper ends of the branch slots D whenever the back is swung up into supporting positions. c

Having thus described my invention, I claim as new and desire to secure by Letters Patent said. brackets to assume a folding or sup-' p 1. A folding back for the saddle of a motorcycle, bicycle and like -machine, comprising brackets fixed to the saddle, a back having side arms mounted to swing on the porting position, the said side arms having lengthwise extending slots terminating in angular branch slots, and a handle fulcrumed on the said brackets and provided with arms having pins engaging the said slots to lock the said back against accidental folding movement when in supportingposi- Copies of this patent may be obtained for tion with the pins engaging the angular branch slots.

2. A folding back for the saddle of a motor cycle, bicycle and like machines, com prising brackets fixed to the saddle, a back having side arms mounted to swing on the said brackets to assume a folding or supporting position, the said side arms having lengthwise extending slots, terminating in angular branch slots, a handle fulcrumed on the said brackets and provided with arms having pins engaging the said slots to lock the said back against accidental folding movement when in supporting position with the pins engaging the angular branch slots, and springs attached at one end to the said side arms and at the other end pressing the said pins.

3. A folding back for the saddle of a motor cycle, bicycle and like machine, comprising-brackets adapted to be attached to the under side of the saddle at the back thereof, a rod connecting the rear ends of the said brackets with each other, a back having side arms mounted to swing on the said rod as a fulcrum, the side arms having prising brackets adapted to be attached to the under side of the saddle at the back thereof, a rod connecting the rear endsof the said brackets with each other, a back having side arms mounted to swing on the said rod as a fulcrum, the side arms having lengthwise extending slots terminating at their outer ends in branch slots extending forwardly and upwardly, a shaft journaled in the said brackets and located a distance in front of the said rod, handles attached to the said shaft, and arms attached to the said handlesand having pins engaging the said slots, the said arms being adapted to rest on the said connecting rod to limit the downward swinging motion of'the said arms.

In testimony whereof I'have signed my name to this specification in the-presence of two subscribing witnesses.
