BICYCLE.

SPECIFICATION forming part of Letters Patent No. 585,043, dated June 22, 1897.

Application filed July 20, 1896.

To all whom it may concern:-

Be it known that I, CHARLES H. METZ, of Waltham, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Bicycles; and I hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification.

This invention has reference to improvements in bicycles and similar vehicles, and relates particularly to the construction of the swiveled portion, in which the steering-wheel is mounted.

The object of the invention is to improve the construction of the yoke or crown connecting the arms, between which the wheel is operatively mounted and in which the spindle is secured to this end.

The further object of the invention is to so construct the yoke or crown that the lateral motion of the spindle with reference to the fork-arms will be resisted at bot-h sides by double inclined struts, the lines of lateral re-v sistance of each pair being in different horizontal planes.

. Another object of the invention is to so construct a yoke or crown of this nature that a sudden impact on the wheel or on the spindle may be distributed through the members of which the crown is composed and resisted by all of said members in combination.

Another object of the invention is to provide a light and durable crown having the greatest vertical extension without interfering with the running of the wheel and without the unnecessary lifting of the steeringhead.

The invention consists in a crown composed of members, the centers of each pair of the members being bent in opposite directions out of the planes of their end portions.

The invention also consists in a crown or yoke comprising a series of inclined strutplates.

The invention also consists in a crown having a lower member having end portions adapted to be secured to the fork-arms, upwardly-inclined struts,and a connecting-plate between the struts to receive the lower end of the spindle.

Serial No. 599,849. (No model.)

The invention still further consists in such other novel features of construction and combination of parts as may hereinafter be more fully described, and pointed out in the claims.

Figure 1 represents an elevation of portions of the fork-arms and of the spindle,the crown being secured thereto and a portion of the wheel being in position. Fig. 2 represents an elevation of the crown-plates, shown slightly separated. Fig. 3 represents a plan view of the lower crown-plate.

responding parts throughout.

In the drawings, 5 indicates the spindle, which is of usual construction and. is generally journaled in the bicycle-head. 6 and 7 are the fork-arms, between the lower ends of which the shaft carrying the wheel 8 is mo unted. The crown or yoke forming the connection between the arms 6 and 7 is formed of three members 9, 10, and 11. These are constructed separately in any well-known manner, as by forging in dies, and are afterward brazed together and to the arms 6 and 7 and the spindle.

The member 9 has the

end portions

12 and 13, with the

openings

14 and 15 of a crosssectional shape to correspond with that of the arms 6 and 7 and to closely lit the same. From the

ends

12 and 13 extend the u pwardlyinclined struts 16 and 17, which are connected by the plate 18, having the opening 19 to receive and closely fit the lower end of the spindle. The member 10 is of similar construction to that marked 9, its

ends

20 and 21 having openingsto receive the arms 6 and 7 and the central plate 22 having an opening to receive the spindle 5. The

struts

23 and 24. of this plate 10 incline downwardly from said ends.

The top member 11 has the ends 25 and 26, which rest on the upper ends of the arms 6 and 7, the inclined struts 27 and 28, extending upwardly from the ends, and the center plate 29, having an opening to receive the spindle 5.

The

center plates

18 and 22 of the members 9 and 10 are brazed together, and the

ends

20 and 21 of the member 10 are similarly secured to the ends 25 and 26 of the member 11, the openings in the members being in alinement. The arms 6 and 7 are now passed through the Similar numbers of reference designate coropenings in the ends of the members 9 and and pressed against the ends of the member 11. In this position these arms are secured to the end plates by brazing.

Reference to Fig. 1 of the drawings will indicate that, with relation to the arms 6 and 7, the spindle 5 is substantially supported by the inclined struts 16 17 and 27 28, the forward or backward pressure at the ends of the spindle or a breaking strain on the upper end of the spindle and the lower ends of the arms 6 and 7 is resisted by the leverage of the

plates

22 and 29 on the spindle and of the ends 12 13 and 21 and 26 on the arms 6 and 7, while a lateral breaking strain on the same portions will be resisted by the pairs of

struts

16 and 23, bearing against the lower end of the spindle, and by the pair of struts 24: and 28,1'esisting the upper portion, or if the strain is in the opposite direction by the corresponding pairs of struts.

Attention is particularly called to the large vertical extension and leverage of the crown on the arms 6 and 7 without interfering with the working of the wheel, the crown being secured to said arms as low down as possible.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A crown for bicycle-forks comprising a vertical series of inclined struts having sufficient width to resist a torsional strain, and portions forming connections between the struts and the fork-arms.

2. A compound crown forbicycle-forks com- 9 having the

ends

12 and 13 furnished with the

openings

14 and 15, the inclined struts 16 and 17 extending from the ends, and connected by the plate 18 having an opening, the member 10 having the plate 22 united to the plate 18 and furnished with an opening,

the

struts

23 and 24 inclined upwardly from said plate, the

ends

20 and 21 extending from the

struts

23 and 24 and having openings, and the member 11, the ends 25 and 26 of which,

are secured to the

ends

20 and 21 of the mem- 5o ber 10, and having the inclined struts 27 and 28 and the perforated plate 29 as described.

4:. In a crown for bicycle-forks, the combination with the fork-arms, and the spindle,

of a plurality of cross members secured at their ends to the fork-arms and having their central portions bent out of the plane of the ends and secured to the spindle.

5. In a crown for bicycle-forks, the combination with the fork-arms, and the spindle, 6')

of a lower member, secured to the fork-arms below their upper ends and having its central portion bent out of the plane of its ends and secured to the spindle, and an upper member secured to the fork-arms and to the spindle.
