XVILLIAM H. CROSBY AND THEODORE J. TELLEFSEN, OF BUFFALO,
NEWV YORK.
S EAT- POST BRACKET.
SPECIFICATION forming part of Letters Patent No. 600,276, dated March 8, 1898.
Application filed June 3,1895. Serial No. 551,435. (No model.)
To all whom it may concern.-
Be it known that we, WILLIAM H. CROSBY and THEODORE J. TELLEFSEN, citizens of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Seat-Post Brackets, of which the following is a specification.
Our invention relates to an improved seatpost bracket for bicycles, formed from a single piece of sheet metal, and will be fully and clearly hereinafter shown and described, reference being had to the accompanying drawings, in which- Figure 1 represents a face view of the sheetmetal blank. Fig. 2 represents an inside face view of the blank after having passed through the stamping-die. Fig. 3 is a side elevation of the same, looking in the direc tion of the arrow V, Fig. 2. Fig. 4 is an end elevation looking in the direction of the arrow 1V, Fig. 2. Fig. 5 represents a side elevation of the completed device. Fig. 6 represents a top view of the same, showing the rear slotted tightening portion. Fig. 7 represents an inverted plan view of Fig. 6 on a reduced scale.
Referring to the drawings in detail, the first operation consists in cutting the blank. (Shown in Fig. 1 in the usual way in a die.) The two curved parts 1 and 1 in said Fig. 1 represent those parts of the blank which form after passing through the second operation and being pressed into shape in a die, as in Figs. 2, 3, and 4, the rear hollow clamping portions 2 and 2 of the completed de-- vice. The inward-curved sides or edges 3 and 3 and 3 and 3 of said blank (see Fig. 1) become the straight parallel sides 4 and 4 and 4 and 4 of the semicircular or concave portions 5 and 5 (shown in Figs. 2 and 4) and form the two halves of the tubular seat-post A. (Shown in Figs. 5, 6, and 7.) That portion-of the blank having the slightly-curved sides or edges 7 and 7 and the straight edge 8 form during the said second operation the two substantially semicircular or concave portions 9 and 9, having the sides or edges 10 and 11. (Shown in Figs. 2, 3, and 4.) This operation is done in a well-known pressing or stamping die, all the several parts being brought into the shape substantially as shown in the said Figs. 2, 3, and 4 at the same time. The next or third operation consists in forming the stamped or pressed blank (shown in Figs 2, 3, and 4) so as to bring the parts in tubular form and the edges 10 and 11 together and the edges 13 and 14 nearly together, thereby completing the device and forming the backwardly-inclined saddle-seat tubular portion A and the substantially horizontal tubular portion B and the hollow clamping portions 2 and 2, substantially as shown in Figs. 5, 6, and 7.
It will be noticed that the edges 13 and 14 (see Figs. 6and 7) do not come close together. The object of this construction is to allow the portions 2 and 2 to be drawn toward each other and thereby tighten the tubular portion A rigidly to a seat-post to which it may be attached, the usual bolt and nut 15 (shown in Fig. 7) being used for that purpose.
This seat-post bracket is secured to a bicycle-frame in the well-known manner by brazing or by other well-known means. It is constructed, preferably, of sheet-steel and makes a light but very strong device for the purpose for which it is adapted.
We claim as our invention A seat-post bracket for bicycles, stamped from a single piece of sheet metal and formed with a straight end 8, the opposite side portions 7 and 7 merging in theinwardlycurved side portions 3, and forming the side of the sheet, the two upper outwardly-curved diverging end portionsl and 1, a slot separating said end portions and bounded by the interior inwardly-curved side portions, 3', and comprising, when stamped into shape, two duplicate half portions, each consisting of a semicircular concavo-convex forwardextending portion, a semicircular concavoconvex downwardly-extending portion, and a hollow clamping portion at the rear of the downwardly-extending portion, the two said portions being bent in relation to each other so that thetwo fortvm d-extending, portions form a tube tore,ce,i ze the end of thetop' frame-tube, and when fitted thereto expose no joint to an upper View, the downwardlyextending portions forming a tube to receive the end of the seat-post-frame tube, and the 7 t JAMES SANGSTER,
two clamping portions forming a device to receive'a screw-bolt to clamp the downwardlyextendingportions around the seat-post, substantially as described;
