RICHARD S. TRUE, OF SYRACUSE, NEW YORK, ASSIGNOR TO THE R. S. TRUE COMPANY, OF SAME PLACE.

BICYCLE-SADDLE.

SPECIFICATION forming part of Letters Patent No. 495,442, dated April 11, 1893.

Application filed April 4, 1892- Serial No. 427,715. (No model.)

T0 on whom it may concern:

Be it known that I, RICHARD S. TRUE, a citizen of the United States, residing at Syracuse, in the county of Onondaga and State of New York, have invented certain new and useful Improvements in Bicycle-Saddles, of which the following is a specification.

My invention more especially relates to the seat and its supporting-springs, of a bicyclesaddle, and contemplates the production of a convenient, simple and easy-riding saddle, readily adjustable both in regard to the tension of the seat and its supporting-springs, their position relatively to their support on the bicycle-frame, and the variation of their angle relatively to their normal horizontal position or plane.

My invention constitutes an improvement on the bicycle saddle shown in United States Letters Patent No. 455,027 granted to my assignee, Thankful E.'True, June 30, 1891, and mypresent improvements consist in certain novel constructions, combinations and organizations of instrumentalities herein described and particularly designated in the claims.

Unless otherwise indicated, the parts are of usual approved construction and operation.

In the accompanying drawings,Figure 1 represents aperspective View of my improved bicycle saddle, detached from its support; Fig. 2, a side elevation thereof,including its support, on an enlarged scale, showing the seat in vertical, central, longitudinal section; Fig. 3, a plan view of the under side of the seat; Fig. 4, a vertical cross-section through the seat on the line 44 of Fig. 3. Fig. 5, shows a rear perspective view of the cantle frame detached; Fig. 6, a rear elevation thereof; Fig. 7, a detail View, in side elevation, of the supporting clamp with one of its clamping-disks or washers removed; Fig.8, a vertical cross-section through the clamp; and, Fig. 9, an elevation of theinner face of one of the clamping-disks.

The usual supporting-rod or standard A, is shown as provided with a substantially horizontal longitudinal bracket-arm a, on which the supporting-clamp B, turns freely and slides longitudinally, being provided with an eye I), and a set-screw b, to hold it in the position desired. The central upright plate B.

of the clamp, is shown as provided with a double flanged rim and a central perforation. Radial corrugations 29 ,19 on-the faces of these flanges, engage with corresponding corruga tions 0 on the inner faces of the flanged cupshaped clamping-disks or washers G, placed on opposite sides of the clamp-plate B, and firmly clamped thereagainst by a screw-bolt c passing through both the washers and the plate, and provided with a nut c at one end.

Longitudinal recesses in the clamping-disks receive the central supporting spring-rods D, which are adapted to slide freely endwise in the clamping-disks, which, in turn can be rocked on their central screw-bolt or pivot c, and securely clamped at any desired inclination, thus enabling me readily to move the rods backward or forward in the clamp, or to vary their inclination, so as easily to adjust the saddle to the size or weight of the rider. The drawings show the spring-rods as passing through the clamp below its pivot; but Fig. 7

shows the recesses in the clamp-disks as duplicated so that the spring rods may be clamped above the pivot as indicated in dotted lines, thus giving a wider range of adaptability to the saddle. The entire spring is shown as double or with its parts duplicated, as usual, though a single proportionately stronger spring would obviously serve the same purpose, though less efficiently.

' The central spring-rods D, carry coils D, at the front or bow of the saddle, the outer arms d, of which terminate under the seat H, and are bent inward to enter a sleeve 11, or these'arms may be united to form a bar, around which the tongue-strap of the bracing strips I passes, as hereinafter more fully explained. The opposite ends of the spring-rods respectively carry coils e, connected by short springarms E, with coils e, in turn connected by spring-arms F, with coils F, the outer ends or arms f, of which are bent into hook-shape and inserted into holesin studs g, on the outer side of the cantle frame G. These coils F, which I call the cantle-coils, are shown in the drawings as lying between the spring-rods D,-

and seat H, and assomewhat larger than the bow-coils D, thus givingslightly more play to the rear end of the seat, while the outer lower coil e, and inner coil 6 are shown as of equal 7 size, but of a somewhat smaller diameter than the bow-coils. The bow and cant-le-coils are also shown as projecting slightly beyond the front and rear of the seat respectively, While the lower center coils e do not extend quite so farbackward as the cantle-coils, below, be-

. at as, to the seat at or near their junction.u

rods D. The above explained-organization enables me to bring the seat closer to its support, and to use longer connecting-arms between the coils than could be done with the connecting-arms and coils between the-supporting spring-rods and the seat as isthecase in my patent above mentioned.

The cantle-frame G, is shown as consisting of a peculiarly-curved concavo-convex arched or bow-shaped bar, witha central boss or swell .1

g. :Thebracing strips I, pass over the back of the cantle-frame, and lie in the depressions 2', between the-central boss and the outer ends' of the 203111116-f12t1116, so as to make any even orflush surface over thecantle-frameforthe seat H.

The seat'proper H, of flexible .material, is shown as connected directly withthecantleframe and as having no other support .than said cantle-frame, andthe arms of the bowcoils, thusincreasingits elasticity. .EThe middle portion of the seat is made: in the shapeof a centrally depressed longitudinal gusset"- or gore h,- and thinner thanthe outerportions,

so as to prevent undue pressure on the overlying parts of the rider when seated.

Bracing-strips I, preferably of stout leather,

passover and are secured to, the back of the cantle-frame in the recesses Z, and extend for-.

ward under and close to-the seat on each side of its central depression, or groove h. These strips converge toward the saddle-bow, and unite witheach other near it being secured These strips terminate in a tongue-strap 2', which. encircles the loop or; stem d, of the bow-coils, and then passes backwardthrough a buckle is, secured on the forward converg ing ends of the adjusting-strips K, secured to the under side oflthe bracing-strips near their rear ends. By this organization, the springtension may be adjusted, and yet leave the seat and spring free toyield to prevent undue shocks to the rider in traversing rough .sur-' faces. The seat not being attached directly to the bow-springs but to the bracing-strips,

is free to flex crosswise, and its outer edges also tend to bend :inward and become narrower by use, not only by the yielding or inward turning of said edges, but by thecollapsing of its thinner, central depression or gored portion. I am thus by my improvements, enabled to secure an effective, simple,

convenient, safe, readily-adj ustable and easyriding bicycle-seat'admirably adapted to the needs of the rider.

Having thus fully described the construction and operation of my improved bicyclesaddle, what I claim therein as new and as of my own invention is 1. The hereinbefore described saddle-spring comprising a central supporting portion or spring-rod D, a bow-coil D, and a cantle-coil F above the rod D, both adapted to connect said central supporting portion and the seat, a spring-arm E, below thecentral supporting portion, and connected therewith, a second spring-arm F, connected with the first mentioned spring arm E, and with the cantle-coil F, and the device 13, for connecting the rod D to the bicycle-frame attached to. the rod D in front of the rear end ofthe. spring-arm E, substantially as set forth. 7
