BICYCLE-SADDLE.

SPECIFICATION formingpart of Letters Patent No. 568,973, dated October 6, 1896.

Application filed March 12, 1895. Serial No. 541,421. (No model.)

To ctZZ whom 212? m by concern:

Be it known that I, ARTHUR L. GARFORD, a citizen of the United States, residing at Elyria, in the county of Lorain and State of Ohio, have invented certain new and useful Improvements in Bicycle-Saddles; 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 improvements in bicycle-saddles, and particularly to the mech anism for adjustably connecting the seat or cover with the frame, whereby the said seat may be tightened or loosened, as desired.

The object of the invention is to provide a simple, cheap, and easily-operated adjustable connection between the seat and saddleframe; and the invention consists in the construction and combination of parts hereiuafter described and claimed.

In the drawings, Figure 1 is a side view of asaddle containing my invention, a part of the seat being cut away. Fig. 2 is a longitudinal vertical sectional view of the adjustable connection between the seat and frame. Fig. 3 is a front view of the saddle, and Fig. at is a perspective view of the plate D.

Referring to the parts by letter, A represents the saddle-frame, which may be made of any suitable material and in any desired form. In the form shown it is made of a single piece of flat spring-steel, which is curved substantially as shown, and its rear end is bolted to the cantle F. At the front end of this spring are the two substantially parallel cars a a, which lie approximately at right angles to the spring. The car a is formed by turning up the end of the spring, and the ear (1, is the projecting part of an angle-plate which is riveted to said spring.

An internallythreaded sleeve O lies in holes in the two ears a a. This sleeve is formed as a cylinder with an external annular flange c at one end; but in order to prevent the sleeve from turning in the ears Ct a the sleeve is flattened (by grinding it oif) at its rear end, and the hole in the car a is shaped to fit it. lVhen the sleeve is passed through the holes in said ears, the projecting rear end of said sleeve is upset, thereby preventing its removal.

The two ears a a and the sleeve 0 are provided for the purpose of furnishing a bearing in which the adj ustin g-screw, hereinafter described, may turn. Although this specific form of bearing is, in my opinion, neater and cheaper than any other, and although it is of my invention, nevertheless the. construction of this bearing may be varied to a considerable extent without affecting the mode of operation of device and without departing from the invention as claimed in those claims which do not specifially name this particular form of bearing.

D represents a plate, preferably stamped from sheet metal, having three arms cl cl cl, which are bent backward into different planes approximately at right angles to the plate itself, and are secured by means of rivets or other means to the under side of the front end of the seat, and when so secured the middle part of said plate lies at substantially right angles to the top of the seat.

E represents a screw which fits and screws into the sleeve 0. Its front end is cylindrical and lies in ahole d in the plate D. Just back from its front end is an annular flange c, which bears against the plate D. In the front end of this screw is a slot with which a screw-driver may engage. The front part of the seat is not bent down, as is common in bicycle-saddles,wherefore a screw-d river may be easily caused to take into said slot. The above construction is very simple and cheap in construction, very neat in appearance, and very effectire in operation, for it is apparent that as the screw is turned so as to move it out of the sleeve the flange c is pressed against the plate D, thereby tightening the seat-leather.

I am aware that the described saddle is not the first which employs a screw asthe means for adjusting the tension of the seat, andl do nottherefore seek to claim, broadly, the use of a screw for this purpose.

Having described my invention, I claim- 1. In a bicycle-saddle, the combination of a saddle-seat bent downward at the sides but not at the front end, and a transverse vertical plate having side arms which are secured to the downwardly-tnrned sides of the seat near the front end thereof, and a rearwardlyextended arm which is secured to the under side of the seat, with a seat-support secured to the rear end of the seat, and having at its front end two separated vertical cars, a threaded sleeve extending between and secured to said ears, a screw which screws into said sleeve and has a cylindrical front end which passes through a cylindrical hole in the transverse plate, and an annular flange which bears against the rear side of the said plate, said screw having a longitudinal slot in its front end, substantially as and for the purpose specified.

2. In a bicycle-saddle, the combination of a flat-spring seat-support having an upwardlyturned end, an ear lying parallel with said end and secured to said support, an internally-threaded sleeve lying in holes in said ear and end, one of said holes being uncylindrical, and the part of the sleeve lying in said hole being correspondingly sliaped,said sleeve having an external annular flange at one end and having its other end upset, with a seat, a transverse plate secured to and projecting downward from the under side of one end of said seat and having a hole through it, and a screw adapted to turn in said sleeve, having a cylindrical front end which extends through the holes in said plate, and having an annular flange which bears against said plate, substantially as and for the purpose specified.

' In a bicycle-saddle, a stamped metal plate having a hole through it and having three arm's bent backward from the top and sides thereof and lying in planes approximately at right angles to the plane of said plate, substantially as and for the purpose specified.

4:. In a bicycle-saddle, the combination of a saddle-seat bent downward at its sides but not at its extreme front end, and a transverse perforated plate lying beneath said front end and having three rearwardly-extended arms which are respectively secured to the top near the front end thereof, and the two adjacent downwardly-turned sides of said seat, with a seat-support secured at its rear end to the rear end of said seat, a bearing for an adjusting-screw secu red to the front end of said-seatsupport, and an ad justing-screw which screws into said bearing and has (i) a cylindrical front part which passes through the perforation in said plate, and is slotted in its front end to receive a screw-driver, and an an-'
