Be it known that I, HENRY LA CASSE, of Rochester, in the county of Monroe,'i1i the State ofNew York, haveinvented new and useful Improvements in- Bicycles, of which the following, taken in connection with the exact description. p I
My'invention-relates to improvements in bicycles, and has for its object the produc tion of a. simple and efiective device, which is economicallyproduced, and is extremely easyin use, obviating the customary jar ex- 1 perienced when passing over rough surfaces; and to this end it consists; essentially, in 'a frame having front'and rear. wheels, atront fork, a link between the lower end of the fork and the front axle, amovable support for the pedal shaft hinged to' the frame, and a seat supporting framecarried by the pedal shaft support whereby both the seat and'the pedal move with the same vibration. o p
The invention also consists in the detail construction and arrangement of the parts of my bicycle, all as *here'inaftermore fully described and pointed out in the claims.-
In describing this inventiomreferenceis had to the accompanying drawings, forming a part of this specificatiomin which, like letv .ters indicate corresponding parts in-all the views.

ing moreo'r less movement, and,,as his feet Io o iare'monnted bn the pedals secured to a rig'- idly moufrited pedal.shaft,-great ditficulty is minimum the transmission of jar to the riders body and feet, and causes said parts to move uniformly and simultaneously. 7
A-- represents the frame of my bicycle composed preferably of a pair of similarly arranged bars or tubes ahaving their" front extremities bent upwardly at a' and approximated a greater distance than the rear extremities -'"a The front bracket -'-B' is adapted to support the steering rod C, and is formed with a rearwardly extending arm b. having sockets b"in which the front endsof the frame bars a-aare suitably secured as by brazing. The outer sleeve D- for the lower end of the steer-- ing rod ---C is adapted to receive at its lower end the upwardly projecting nipple-erigidly secured to the front fork -E-. This sleeve D-- is formed with a bearing face -dbetween which and a likebearing face 7 ZJ2- on the front bracket B- are interposed anti friction balls -D- for reducing .to a minimum the friction efiected when turning the steering red -O. The upper end of the outer sleeve -D- is also formed with a roller bearing d' between which and a corresponding bearing b on' the upper end of the bracket. 'B areinterposed anti'friction balls --D and the said upper extremity is further supported by a nut --D screwing upon the sleeve -D- and formed with a depending flange D adapted to cap over the upper end of the bracket B--. The extreme upper end of the'sleeve -D' is slightly tapered andis slotted at 'd?- and screwing thereuponis a n nt--d which is formed with a slightly tapering innerper 'riphery and clamps the separate sections of said extreme'upper end ofthe sleeve -D-. against the. periphery of the steering ro'd -C- inserted: within said sleeve.
At the extreme upper end of the steering rod -(J- is a cap formed with upturn ed ears --fthrough which is passed the handle bar F' consisting of separate sections having their adjacent extremitiesprovided with'oppositely turned threads and engaged with a socket -f'- in the lever presently described, in connection with the brakemechanism; said oppositely threaded. ends being held in position bya pin F passed th rough an aperture in said lever, and a corresponding aperture in the, handle bar formed by a groove in the adjacent facesof its separate sections. The opposite arms -'-e' of the fork E- are arranged on opposite sides of the front wheel'-G.
with a central aperture =g in which are I rigidly secured the opposite metallic sections g --g having their outer ends formed flaring and provided with ball bearing seats ablyless diameter than the sections --g and is supported in position by means of anti friction. balls h-r-interposed between the bearings g and corresponding bearings h-- secured. to the axle l-I, or, as illustrated, to the inner face of the huh I'- formed on thelinks -I- for yieldingly supporting the lower ends of the fork arms e'- upon said front axle; The upper ends of the'links -I- are formed on their inner face with a recess -ihaving inner and outer flanges t"- and -t*- in which is mounted a spring-1 having one end t' secured to the link, and the other ito the lower end of the fork arms e'-. arms are formed with a hub -e*-- movable in The front axle H is of consider- These lower ends of the fork a slot -I in the outer flange 'i and .with a hollow boss e journaled withinthe innerflange --'i' of ,the link .I- and secured in position bya suitable clamp as a nut and bolt --I. The huh I of .the links -I, which, as previously stated, is formed with the ball bearing face h, is rigidly secured to the axle .-l-I being preferably screwed thereon and held in position by a locking nut--H', the end of the shaft -H being formed with a slot H for enabling the same to be firmly held wb 11 the nut-H'- is screwed in position.
In the use of my bicycle the spring -1 constantly forces the front face of the fork arms -e'-against the front wall or shoulder i of the slot i as best seen at Fig. 2, and, as the wheel encounters an obstruction, the axle moves upwardly against the action of the spring until the rear face of the fork encounters the rear wall or shoulder t'" of the slot, which can only happen when the wheelie excessivelyjarred so .as to entirely overcomethe force of the spring '-z.- The fork and its flexible connection reduce to a minimum the amount of jar ordinarily transmitted to the handle bar and renderthe riding of the bicycle much more pleasurable and healthful than when the same is c0ntinually jarred by passage over obstacles.
J-- represents any suitable construction of front. mud guard,.which may be su'itably supported, as by means of a suitable brace J'-- and downwardly projecting ears jupon a support j" for one of the brake 'actua'ting levers, presently described.

The lever -L when in its normal position extends upwardly and forwardly from the lower arm --F- of the leverL and the'lever -L' extends rearwardly from the forwardend of said lever -L as best seen at Figs. 1, and
2, thus requiring the smallest possible space for said knuckle, and causing the same to be extremely firm, although capable of instantly yielding to preventtransmission of jar to the The rider as more clearly shown hereinafter.

sprocket wheel --X is rigidly secured to the adjacent sleeve w' and is engaged by a nut X' formed with an inwardly extending hub .r having a bearing face a" for the adjacent anti friction balls 'w and is also formed with a flange X on the outside of the hub w'. Upon the opposite section of the axle is adj ustably mounted a shoulder Y having a bearing face yfor the anti friction balls w-- and formed with a series of apertures y-- with which is engaged at suitable stop Y' for preventing the retraction of said shoulder.
It will be readily noted that, by means of the. nuts -w the supports -W may be readily adjusted for taking up all slack in the sprocket chain X In order to facilitate mounting of the bicycle one extremity of therear axle is extended outwardly and formed with a foot engaging portion W. V I
The brake mechanism P- consists of a suitable shoe P' jo'urnaled onj the hub L- of the pedal supporting lever -L and suitable connections between the upper extremity of said shoe and the lever 'f secured to the handle bar -F---. As preferably constructed these connections consist V of a lever ;p',- pivoted at Pp to a support '-p upon the frame -A, and coni 1 nected by a link -p passed through the arm f 0- to the brake shoe.P- a I lever pivoted to a lug -p'*- on the rear arm of the front bracket -B-, and connected: to the lever p' by a link ---.p"
passed through the spring S- ahd a third lever --p pivoted to the support -;7"- previously described, and connected by a horizontally jointed link -p to the lever ;-p and by a link p to the end of the ,lever tween said arms -p and a shoulder ,-p
on the link -p constantly forces said link p 9-- downwardly and throws the shoe out of engagement with the rear wheel -W-.
7 When desired to utilize the brake the rider bears downwardly in a natural movement of stronglyigr'ipping the handle bar when danger is apparent, and the connections between the brake shoe and the lever secured to said handlebar force the brake shoe firmly against the rear wheel against the act-ion of thespring ---P. This forms a particularly simple and eflfective style of brake, and is an essential feature of my invention.
The'operation of my invention will be readilyper'ceived from the foregoing description and upon reference tothe parts. It will be particularly noted that the handle bar is almost entirely preventedfrom' jar, and that, when the frame-is jarred, this motion is not transmitted to the rider, as both his feet and his body are supported yieldingly upon the frame by means of the yielding support for the treadle shaft and the seat supporting frame, which is carried upon the support for the treadle shaft. J
It will be understood that the detail construction and arrangement of the parts of my invention may be somewhat varied from those shown and described without departing from the spirit thereof, hence I donot herein limit myself to such detail construction and arrangement.
