BICYCLE-FRAM E.
SPECIFICATION forming part of Letters Patent No. 662,115, dated November 20, 1900.
Application filed April 20,
T0 all whont t pta/y concern:
Be it known that I, JOSEPH S. DIKEMAN, of Torrington, in the county of Litchfield and State of Connecticut, have invented certain new and useful Improvements in Bicycle- Frames; 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 an improvementin bicycle-frames, and is designed more particularly as an improvement on the construction disclosed in my Patent No. 647,812, granted to me April 17, 1900.
My invention consists in the combination of a ring provided with necks or lugs for the attachment of the forward reach and central brace, end rings each having a neck or lug for the attachment of a rear stay, and a twopart crank-bearing located within and carrying said end rings and secured to the central ring.
My invention further consists in the combination of a central ring having two lugs or necks thereon, two end rings interlocked with the central ring and having lugs or necks for the attachment of the rear stays or braces, and a sectional crank-bearing supporting said end rings and secured to the central ring.
My invention further consists in the parts and combination of parts, as will be more fully described, and pointed out in the claims.
In the accompanying drawings, Figure lis a view in side elevation of'myimprovement. Fig. 2 is a view in section of the same. Fig. 3 is a view showing the several parts detached, and Fig. l is a View of a modified form of central ring.
A represents a split ring provided with two lugs or necks a and b, the former of which is for the permanent attachment of the forward section of the reach, while the latter is for the permanent attachment of the central or seat-post tube of the ordinary safety-bicycle frame.
In Figs. l, 2, and 3 I have shown this ring provided at its edges, adjacent to the slit therein, with the ears c d, the former of which is perforated for the free passage of a screwbolt d, while the latter is threaded internally 1900. sena No. '13,643. No man.)
for engaging the threads of said screw-bolt. This ring A is also provided at its side edges with laterallyprojecting ears e, which latter tit within similarly-shaped recesses e/ in the end rings B B', thus locking the three rings A, B, and B' against rotary displacement. The end rings B and B' are each provided with a rearwardly-projecting lug or lugsf, to which the rear stays or braces are secured by brazing or otherwise. The three rings A, B, and B' are secured together and retained against lateral displacement by the two-part crank-axle bearing C. Each section of the bearing C is provided at its outer end wit-h a flange g, which overlaps the adjacent end ring and prevents lateral displacement thereof, and each section is also screw-threaded externally at its inner end to engage female threads formed on the inner face of the central ring A. It will thus be seen that by assembling the three rings A, B, and B and securing the two-partorank-hanger bearing therein that the end rings B and B are retained against lateral displacement or separation by the end flanges g, while the ears e and recesses e prevent any rotary displacement of the rings. The notches in the Iianges g of the bearing-sections C are for the application of a wrench employed for securing the sleeves into position. thus been assembled they can be still further locked by tightening up bolt d in the ears c and c of the ring A. Each section C of the crank-axle bearin g is counterbored at its outer end, as shown at 7L, for the reception of the bearing-cups, (not shown,) adapted to support the ball-bearings in which the crank is mounted. With this construction it is evident that the rings B and B and stays carried thereby may be removed and replaced without disturbing the rest of the frame. This is found especially desirable in assembling the frame. I have also shown the rings B and B each provided with two necks or lugs f for the attachment of Atwo stays, such as shown and claimed in United States Patent No. 63l,282, granted to C. S. Dikeman August 22, 1899; but it is evident that I may employ rings each having one lug only or more than two, the number of necks or lugs on each ring B and B' being unimportant.
After the parts have IOO By constructing the parts so that the crankbearing may be vreadily removedand replaced it enables the bearing, with its bearing cups and balls therein, to be readily and quickly removed for cleaning, repair, and renewal.
In Fig. 4c I have dispensed with the slitted central ring shown in Figs. l and v2 and employ a solid ring. Itis also evident that other f slight changes in the construction of the several parts might be resorted to without departing from the spirit of my invention. -IIence I would have it understood that I do not confine myself tothe details herein shown and described, but considei` myself at liberty tol make such changes as may fall within the spirit and scope of my invention.
Having ,fully described `my invention, what I claim asn ew, and desire to secure by Letters Patent, `is- 1. The combination with a ring Aprovided with necks or lugs for the attachment of the forward .reach and central brace, and end rings, each having `a neck or .lug for the attachment of a rearstay, of a two-part crankbearing located within said rings andrsecnred L andracfh `secu red at its inner .end to the ycentral ring.
4. The combination with a central ring and two end rings the central ring being screwthreaded internally of a crank-bearing composed of two tubes eac-l1 having a fiange at its outer end and screw-'threaded externally at its inner end -to engage the female threads on the .central ming.
5. The combination with a central ring and two end rings the said rings being interlocked at their edges `to ,prevent their rotary movement- `or displacement, oia crank-bearing composed of two short tubes each having a flanged onter end and screw threaded inner end, the said screw-threaded inner end adapted to engage female threads on the central ring.
In testimony whereof I 'have signed this to the central ring. specification in the presence of two subscrib- 2. The combination with a ring having two lugs or necks therein .and .two end rings fori the attachment of `the rear stays, of ,a crank-i` bearing composed `of two `tubes each havingi; an end ange, the two tubes being removably ing witnesses.
