CHILDS SEAT FOR BICYCLES.

Specification of Letters Patent.

Application filed September 7, 1910. Serial No. 580,855.

To all whom it may concern:

Be it known that I, lVILLIAM H. MARTIN, a citizen of the United States, residing at Bisbee, in the county of Cochise and Territory of Arizona, have invented certain new and useful Improvements in Childrens Seats for Bicycles; 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, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in folding childrens seats for bicycles and comprises a simple and efficient device of this nature which may be securely held to the head of the fork and frame of the machine, means being provided for adjusting the chair and for holding it in open relation.

The invention comprises various details of construction and combinations and arrangements of parts which will be hereinafter fully described and then specifically defined in the appended claims.

I illustrate my invention in the accompanying drawings, in which Figure l is a perspective view showing the application of the invention to the frame of the bicycle. chair folded. Fig. 3 is a detail sectional view through a pivotal braceholding member mounted upon the seat of the chair. Fig. 4 is a detail view showing the adjustment of the connections for holding the chair to the frame of the bicycle, and Fig. 5 is a rear view of the back of the seat and the metallic angled members fastened thereto.

Reference now being had to the details of the drawings by letter, A designates the bot tom and B the back of the chair, said bottom having flanges A, and B designates a rightangled metallic member to whlch the back is fastened. The rear end of the seat is pivotally connected to said angled member B by means of the pins B and brace bars, designated by letters C and D, are pivoted the former to the flange A and the latter to said member B, one upon either side of the bottom and back respectively, said braces being pivotally connected together at D.

Pivotally connected to each brace bar D is a bar E and to each bar C a bar E, and

2 is a view illustrating the said bars E and E are pivotally connected by means of the pivotal pin F. A strap G connects the two bars E, being fastened in a slot E therein and is provided for the purpose of holding the child in the seat while the brace bars E, D and C, as well as E, szfive to hold the child from moving latera y.

A foot rest, designated by letter H, which may be made of any suitable material, such as intersecting bars as shown, is provided and the rear end of said foot rest is pivotally connected to the bars I which in turn are pivotally connected to the inverted U- shaped members J which are secured to the under surface of the seat adjacent to its forward marginal edge.

Pivotally connected to the member B adjacent to their lower ends are the strips K which are pivotally connected by means of the pins K with the strips K and strips L are pivoted by means of the pins L to the strips K and in turn pivotally connected at L with the bars I. Links 0 are pivotally connected at O to the strips L and in turn pivotally connected to the links 0 which are pivotally connected to the pins 0 fastened to the strips I. The outer end of the foot rest is held by means of the links P which connect said foot rest with said inverted U-shaped members J.

Fixed to an ear of the bracket member Q, one adjacent to either side of the bottom and fastened to the under face thereof, is a bar R having a recess R formed in its outer face, and R is a s ring fastened to the bar R and adapted to form a closure to said recess and serving to hold the link K therein when the seat is open in the manner shown in Fig. l of the drawings. Said springs serve to hold the parts of the chair from folding. hen the parts are folded, the hooks M which are pivotally mounted upon the member B are adapted to engage the headed lugs M upon the standards A, as shown clearly in Fig. 2 of the drawings.

It will be noted that the backs of said angled members B have slots B parallel to each other and longitudinally formed therein and in which the bolts B are adapted to be adjustably held by means of the nuts upon the bolts, and B are ears which are apertured for the reception of said bolts and each ear carries a pivotal pin B upon which a rod B is pivotally mounted and on the outer end of each rod B is pivotally fas- Patented Nov. 15, 1910.

tened a concaved clamping member B The two clamping members, one mounted upon each of said rods, are adapted to engage the horizontally disposed tubular portion of the bicycle frame and held in clamping relation therewith by means of the bolts B and the nuts B thereon. A bracket member, designated by letter T, is fastened to the faces of the members 13 and has a concaved portion T which cooperates with a clamping plate T to embrace the head of the fork of the bicycle and said clamping members T and T are held by means of the bolts T having nuts T thereon. In order to hold the parts in folded relation, straps S and S are fastened one to each member B, one strap containing a buckle adapted to receive the end of the other strap, as shown in Fig. 2 of the drawings.

From the foregoing, it will be noted that, by the provision of a seat made as shown and described, a simple and efficient device is provided whereby the seat may be securely held to the frame of the bicycle in open relation for use or, when not in use, reduced to a compact form for storage or shipment.
