CONVERTIBLE BREAST AND BACK REST FOR BICYCLES.

SPECIFICATION forming part of Letters Eatent NO. 620,688, dated March 7, 1899. Application filed December 8,1897- Serial No. 661,152. (No model.)

To aZZ whom it may concern:

Be it known that I, JOSEPH W001), a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Convertible Breast and Back Rests for Cyclers, of which the following is a specification.

This invention relates to improvements in a device to be attached to bicycles to afford a rest for the breast or back of the rider; and it consists in certain peculiarities of the construction, novel arrangement, and operation of the various parts thereof, as will be hereinafter more fully set forth and specifically claimed.

The principal object of this invention is to afford a chest or breast rest or support for cyclers which can be readily secured to the upper part of the bicycle-frame, and when so placed may be adjusted to a proper position between the handle-bars and seat, and on or against which the rider can rest or lean, thus relieving the arms of the great strain and fatigue incident to the vibrations through the handle-bars and the continuous grasping of the same, as well as enabling him to exert more power through his feet and legs on the cranks and pedals.

In order to enable others skilled in the art to which my invention pertains to make and use the same, I will now proceed to describe it, referring to the accompanying drawings, in which-- Figure 1 is a view in side elevation of a bicycle, showing my rest attached thereto and in the position it will occupy when used as a breast support or rest. Fig. 2 is a similar view of the rear portion of a bicycle, showing the attachment secured thereto and in the position it will occupy when used for aback-rest. Fig. 3 is a perspective view of the spring-support and upper part of the supporting-arm. Fig. 4 is an enlarged perspective view of the securing-clamp, showing it closed and detached from the bicycle and illustrating its serrated arm or extension. Fig. 5 isadetached perspective view of the adj usting-arm. Fig. 6 is a plan view of a portion of the supporting-arm, adj usting-arm, and a part of the arm or extension on the clamp and illustrating the manner of securing said parts together; and

Fig. 7 is a rear perspective View illustrating a modification in the construction of the springsupport and upper part of the supporting-arm Similar letters refer to like parts throughout the different views of the drawings.

A represents the securing-clamp, which is adapted to be secured to the upper tube A of the bicycle-frame when the attachment is used as a breast-rest and to the saddle-post A when employed as a back-rest. This clamp is composed of two semicircular pieces a and a, hinged together at one of their sides, as at a as shown in Fig. 4 of the drawings. The oppo= site side of the piece ct from its hinged portion is provided with a transverse and open slot or for the passage of the head I) of the screw b,

which passes through an opening in the side of the piece a and is secured by means of a set-nut c of the ordinary or any preferred construction. The upper surface of the piece a may be provided on each side of the slot 0, with indentations or recesses a to receive the head I) of the screw. By loosening the nut c the head 17 may be turned until it is in alinement with the slot a through which it will pass and allow the piece a to be raised, thus permitting the clamp to be removed from the supportingtube. On its upper surface and extendingforwardly the piece a is provided with an arm or extension B, having a series of teeth or serrations b to engage similar teeth (1 on the adj listing-arm D, which is adj u stably secured on the arm or extension B by means of a bolt e, which passes through the openings e ande of the arms B and D, respectively, and a set-nut a which engages suitable threads on the end of said bolt. The opening e in the arm B is preferably rectangular in form to receive the rectangular portion of the bolt e, which construction preventssaid bolt turning therein. Around the opening 6 is formed a boss 6 which fits into the countersunk recess e of the adjusting-arm D, and thus centers the two arms B and D and causes their teeth to accurately register. vided with a longitudinal slot d for the re ception and operation of a bolt f, which passes through said slot and an opening in the lower end of the sup porting-arm E and is secured in place by means of a suitable nut. To the upper end of the supporting-arm E is secured a spring-rest G, which is composed of a bar The arm D is pro- IOO g, secured transversely to the end of the supporting-arm, and two flexible pieces g, which are fastened at their ends to the ends of the bar 9, thus formingabow-spring on each side of the cross-bar. The pieces 9 may be made of any suitable material, and when made of metal may be covered with leather, felt, or other suitable material or may be provided with a pneumatic cushion.

In Fig. 7 of the drawings I have shown a modification in the construction of the springsupport which consists in employing a bar 9 to which is secured, on one of its sides only, a flexible piece h, which is formed into a bowspring, as is clearly shown. In this modification the middle portion of the bar 9 is reduced and formed with a rounded portion g to fit within the sleeve h on the upper end of the supporting-arm and is fixed in the desired position by means of a set-screw 71. located in said sleeve. By using a doubled spring-support, as shown in Fig. 3 of the drawin gs, it is apparent that when the attachment is applied to the tube A of the bicycle-frame, as it must be when intended to be used as a back-rest, that one of the springs g will be in position for the back to rest against, and when the device is used for a breast-rest, as shown in Fig. 1 of the drawings, the other spring will lie against the breast, thus obviatingthe necessity of turning the spring-support on the supporting-arm, provision for which has been made in the modification illustrated in Fig. '7 of the drawings and which will allow the flexible or spring piece h to be turned to either side of the supporting-arm, as is obvious.

WVhile I have shown in Figs. 3 and 7 two forms or modes of constructing the springsupport, yet I do not desire to be limited to either of said constructions, as I may employ other supports and attach them to the supporting-arm E in any suitable manner.

The operation of my device is simple and as follows: To place the securing-clamp A on the desired tube of the bicycle-frame, the cross-head b of the screw 1) is turned so as to pass through the open slot a when the piece a of the clamp may be turned on its hinge and placed over or around the tube, when the head I) may be passed back through the slot a and turned crosswise thereof and secured in position by means of the set-nut c, which will firmly secure the clamp in the desired position. The adjusting-arm D, carrying the supporting-arm E, may be adjusted on the arm or extension B to any desired angle and the supporting-arm E adjusted to any desired position and there secured by means of the bolt f, passing through the slot 61 of the adjusting-arm.

Having thus fully described my invention, What I claim as new, and desire to secure by Letters Patent, is

1. The combination of a clamp having an arm or extension provided with a series of teeth arranged in a circle, with an adjusting arm having at one of its ends a series of teeth to engage the teeth on the arm of the clamp, and provided with a longitudinal slot, means to adj ustably secure the adj usting-arm to the arm of the clamp, a supporting-arm secured at one of its ends in the'slot of the adjustingarm, a piece or bar secured transversely and adjustably to the other end of the supporting-arm, and a spring secured at its ends to the ends of said transverse piece, to form a rest for the-breast or back of the rider, substantially as described.

2. The combination with a clamp comprising the pieces .a, and a, hinged together at their sides, the piece a, having the arm B, provided with serrations and also having the open slot a the piece a, having an opening in its side adjacent to said slot, a screw located in said opening and having the crosshead 17, adapted to pass through the slot a in the piece a, and a set-nut to engage the screw,

of the adjusting-arm D, provided with a longitudinal slot, and having serrations on one of its ends, means to adjustably secure the said adjusting-arm to the arm B, a supporting-arm adj ustably secured at one of its ends in the slot of the adjusting-arm, apiece or bar transversely secured to the other end of the supporting-arm and having secured to its ends a spring to afford a rest for the breast or back of the rider, substantially as described.

3. The combination in a clamp of the pieces a,and a, hinged together at one of their sides, the piece a, having the open slot a and the piece a, having an opening in its side adjacent to the said slot, a screw located in said opening and having thecross-head b, adapted to pass through the slot a in. the piece a, and a set-nut to engage the screw, substantially' as described.
