VELOQlPEDE-SADDLE.

SPECIFICATION forming part of Letters Patent N 0. 464,653, dated December 8, 1891.

Application filed October 21, 1890.

To all whom it may concern:

Be it known that I, EMMIT G. LATTA, a citizen of the United States, residing at Friendship, in the county of Allegany and State of New York, have invented new and useful Improvements in Velocipede-Saddles, of which support the saddle that the same may be tilted into a convenient position for mounting and so that the same may be adjusted to any desired inclination.

Another object of the invention is to prevent the sides of the flexible saddle from yielding excessively under unusual shocks or strains.

In the accompanying drawings, consisting of three sheets, Figure 1 is a side elevation of my improved saddle with a portion of the flexible seat broken away to fully expose its front support. Fig. 2 is a top plan view of the saddle with the flexible seat omitted. Fig. 3 is a top plan view of the seat. Fig. 4 is a longitudinal section of the saddle, showing the same in a normal position. Fig. 5 is a similar view thereof, showing the saddle tilted into the position for mounting. Fig. 6

' is a cross-section in line v t, Fig. 4, showing theconstruction of the spring whereby the portions of the divided saddle are spread apart. Figs. 7 and 8 are cross-sections in lines to w and a: m, Fig. 4, respectively. Fig. 9 is a side elevation of a modified construction of the saddle. Fig. 10 isa fragmentary longitudinal section of said modification. Figs. 11 and 12 are cross-sections in lines y y and 2.2, Fig. 9, respectively.

Like letters of reference refer to like parts in the several figures.

A represents the saddle-pillar, having the usual horizontal extension A, and B is the flexible seat.

0 represents a double coiled spring supporting the rear end of the seat, D a double spring supporting the front end of the seat, and E a curved rigid bar or frame connecting the front and rear springs, and which is capable Serial No- 368,8Z7. (No model.)

of sliding lengthwise in a clip F, secured to the pillarextension. The rear spring is preferably composed of a single piece of wire detachably secured at its bent central portion to the rear end of the frame by a bolt 0 and having its ends secured to the flexible seat in any suitable manner. The rear spring is prevented from sliding upon the curved bar E by a clamping plate or washer c, which straddles the double portion of the spring and is provided with grooves in which the ad jacent parts of the spring are seated, as rep resented in Fig. 8. The clip F is provided with a horizontal opening, through which the pillar-extension passes, and is adjustably secured to the extension by a set-screw f. The clip is formed on its upper side with a concave seat f for the curved bar or frame G represents a trip-lever pivoted at its lower portion to the clip F by means of a horizontal bolt g, passing through lugs or cars formed on the upper side of the clip. This trip-lever is provided at its lower e'nd,on the front side of its pivot, with an eccentric g, which bears against the upper side of the curved bar E when the lever is in the locked position (represented in Figs. 1 and 4,) so as to clamp the same in the clip F. The lever is formed with a curved upper portion and is provided at its lower portion on opposite sides of the clip F with downwardly-projecting arms h 71.

11 represent spiral springs attached at their rear ends to the rear spring 0 and at their front ends to the arms h, respectively, and which tend to swing the lever forwardly, so as to cause the eccentric to clamp the curved bar E against its seat.

j represents a nose or projection formed on the front side of the trip-lever near the lower end thereof, and which engages in a longiis not reliably clamped by the eccentric of the lever the nose j also serves to prevent displacement of the bar in its clip by striking the front end of the slot.

\Vhen the springs I are below the pivotbolt of the eccentric-lever, as shown in Figs. 1 and at, they tend to hold the lever in a locked position, while upon swinging the lever rearwardly to release the bar the springs assume a position above the pivot-bolt of the lever and tend to hold the lever in an unlocked position. The lever is provided in rear of its pivot with a nose or detent 70, which limits the rearward movement of the lever by striking the curved bar E and prevents the springs from pulling the lever rearwardly too far.

When the lever is in the unlocked position, (represented in Fig. 5,) the curved bar may be forced backwardly in the clip to the posit-ion represented in said figure, the springs I being strained or distended by this movement of the bar. The bar is locked in this position by the detent 7; of the lever, which enters a notch or recess 7; near the front end of the bar, as shown. The detent of the le ver is made wider than the slot in the curved bar to prevent it from entering the slot. \Vhen the saddle is thustilted, the curved upper end of the lever projects through a slot or opening formed centrally in the flexible seat. The position of the saddle represented in Fig. 5 is very convenient for the forward mount of a bicycle or tricycle having a depressed reach or main frame.

Upon mounting the tilted saddle the rider strikes the projecting curved end of the triplever and swings the same forwardly. As soon as the strained springs I have passed downwardly below the pivot-bolt of the lever they contract, drawing the curved bar E forward into the position shown in Figs. 1 and 4, and at the same time causing the eccentric of the trip-lever to clamp the bar in place. The saddle is thus thrown forward and upward under the rider automatically without requiring the saddle to be manipulated, it being only necessary to tilt the saddle preparatory to mounting.

Z represents a stop arranged on the curved bar E, and which is adapted to strike against the rear side of the clip F, so as to limit the forward movement of the curved bar in the clip. This stop preferably consists of a screw seated in one of a series of holes arranged lengthwise in the curved bar, so that the in clination of the saddle may be varied to suit the rider by placing the screw in the proper hole.

As represented in Fig. 3, the front portion of the flexible seat is divided to form two parts or members. Each part of the flexible seat is provided at its front end with a plate on, and these plates are secured, respectively, to the upper ends of the front spring, the plates being formed with sockets, in which the ends of the spring are seated. The front spring preferably consists of a single piece of spriiig-wire,which is doubled at its center, and

having its doubled portion secured to the front end of the curved bar E by a bolt 12.

O 0 represent supporting springs or levers attached at their lower portions to the front end of the connecting-bar E and having their upper free ends seated in sockets or cavities formed in the under sides of the seat members. The springs 0 cross each other, as shown in Fig. 6, and are preferably formed of a single piece of wire,which is bent to form a crossbar 0', which connects the springs, the clasticity of the latter being increased by coils formed at the junction of the cross-bar and the springs, as shown. The springs are connected to the curved bar E by a plate P,having an eye, in which the connecting-bar o of the spring is confined, and which is secured to the curved bar E by the same bolt which secures the front spring to the bar.

\Vhen the machine receives an unusual shock, as in striking a stone, the front portion of the saddle moves downward and backward about in the line indicated byl Zin Fig. 1, and the sides of the saddle tend to move inwardly toward each other. This movement depresses the crossed springs O. causing the same to move outwardly and spreading apart the members of the saddle, as approximately shown by dotted lines in Fig. Ordinary ham mock-saddles give way at their outer edges under unusual strains and leave the central part alone to bear the riders weight, causing the central part to sag and producing the trouble known as perineal pressure. By myimprovement the sides of the flexible saddle are forced outward sufficiently to cause the strain to be exerted principally against the fleshy parts of the thigh, thereby relieving the central part of the saddle and preventing undue sagging thereof. The main front spring I) and auxiliary spring 0 both support the front portion of the saddle, and as they extend from the curved bar or frame E to the saddle on diderent lines or at different angles they hold the saddle against undue backward movement, while still permitting the saddle to yield sufficiently to render it comfortable.

It will be observed that the crossed springs act as flexible levers fulcrumed at their lower ends, and that rigid levers might be substituted for the springs, the levers operating to expand the parts of the divided saddle when depressed and being returned to their normal position by the reaction of the front springs D. In either 'case the springs or levers act as an expending device, which causes the parts of the saddle to spread apart when depressed.

In the modified construction of the tilting saddle represented in Figs. 9, 10, 11, and 12 the automatic trip and locking lever is omitted and a clamping device which is operated by hand is substituted therefor. This clamping device consists of a clip P, having a transverse loop 11, through which the curved bar E passes, and a set-screw g and clamping-plate q, whereby the bar is secured in the clip. The lower portion of the clip, through which the pillar-extension A passes, opens into the loop 19, as shown in Fig. 11, so that the under side of the curved bar E bears against the extension, as clearly shown in Figs. 11 and 12, the extension being flattened on its upper side, as shown, to prevent the clip from turning or twisting on the extenmom.

I claim as my invention- 1. The combination,with the saddle-pillar, the seat, and a clip adjustably secured to the saddle-pillar, of a curved bar supporting the seat and capable of sliding lengthwise in said clip to change the inclination of the seat, and
