SPECIFICATION formingpart of Letters Patent No. 663,295, dated De embe 4, 1900.

Application filed April 5, 1900. Serial No. 11,730. (No model.) I

To all whom, it may concern:

Be it known that LERNsT HERRMANN N EU- BERT, residing in Washington, in the District of Columbia, have invented certain new and usefullmprovements in Velocipedes,of which the following is a specification.

lWIy invention is an improvement in velocipedes, and has foran object, among others, to provide a velocipede which maybe driven by the hands of the operator and in which the grips held in the hands may be moved to set the clutch devicesinto and out of adjustment to key the wheels upon the drive-shaft.

The invention has for a further object to provide an adjustable platform to form a support for the operator, which platform may be conveniently raised and lowered by the operator while the velocipede is in use.

The invention has for further objects other improvements; and it consists in certain novel constructions and combinations of parts, as will be hereinafter described and claimed.

In the drawings, Figure 1 is a perspective view of my velocipede. Fig. 2 is a front elevation thereof, parts being broken away and others shown in section. Fig. 3 is a detail sectional view illustrating a portion of one of the spindles and the crank-arm adjacent thereto. Fig. 4 is a detail section on about line 4 4 of Fig. 3. Fig. 5 is a detail perspective view illustrating the brake device. Fig. 6 is a side view, partly broken away, of the stand containing the operating and detent devices for the platform-belts. Fig. 7 is a detail perspective view, partly broken away, of the foot-plate. Fig. 8 is a detail perspective view of a portion of one of the detent-racks. Fig. 9 is a detail vertical section on about line 9 9 of Fig. 6. Fig. 10 is a detail perspective view of the clutch mechanism, partly broken away; and Fig. 11 is a sectional side elevation of the clutch mechanism.

The drive-shaft A is provided at its ends with the spindles B, on which the wheels 0 are free to turn, and between its ends the shaft A is provided with the central portion D, on which is loosely fitted the sleeve D, against which the operator may rest in driving the machine. Between the central portion D and the spindles B the drive-shaft is provided with the cranks E, which are alike and have the wrists E and the outer arms E the latter connecting with the spindles B and being adjacent thereto, as shown.

Clutch devices are provided by which the wheels C may be held at will to the spindles of the drive-shaft, and these may consist of the construction shown, in which the wheels are provided with toothed wheels C, having their teeth C projecting inwardly, andasimilar wheel B is keyed on and slidable along the main shaft and has outwardly-projecting teeth B which may be set into and out of the wheel C, being actuated by a spring G.

Within the spindle B and held at its outer end at G to said spindle and at its inner end to a crosspin H, which extends through a slot H in the non-circular portion F of the shaft and connects at H with the sleeve F on the Wheel B. By this construction the spring G is connected with and is arranged to operate the Wheel B outward into engagement with the wheel C of the supporting-Wheels at all times except when the wheel B is actuated out of engagement with the wheel C, which may be effected in the manner which I will now describe. To this end I provide on the wrists E of the cranks Esleeves I, which are keyed to and movable longitudinally on the said wrists and are connected by a Wire I or other suitable device with the wheel B, so the latter may be drawn out of mesh with the wheel C, when desired, by the longitudinal movement of the sleeve I inwardly upon its wrist E.

I have shown the crank-arm E tubular, with the wire I extended through the same and connected with the cross-pin H, and this construction may be preferred, because thereby the operating parts are incased and not likely to get out of order. I also connect the wire I with the sleeve I by the adjustable connection consisting of the bolt I and the the sleeve I.

nut securing the same to afiangeorear upon The grip-sleeve J is fitted loosely upon the wrist E and is engaged with the sleeve I so it can readily turn upon the said sleeve and yet may be slipped inwardly u on the wrist E and will corres ondin lv P s shift the sleeve I by such operation.

By the described construction the drivewheel 0 may be clutched upon the drive-shaft and may be operated by turning said driveshaft as desired.

while driving the machine and may also be shifted longitudinally upon their supportingwrists to free either or both of the drivewheels 0, as may be desired. By this means the wheels C may be operated or either of said wheels may be freed in order toproperly guide the velocipede during the operation thereof.

A mud or dust guard K fits over the joint between the wheels B and C and is preferably secured to the wheel 0 and extended over the other wheel, as shown.

The operator stands upon a platform K and works the drive-shaft by his hands. The platform K is carried from the drive-shaft and is preferably adjustable vertically. To this end I employ the hangers L, having bearings at L for the drive-shaft, and the platform is provided near its ends with the upright portions K in the form of sleeves, which slide upon the hangers L, so the platform K can be raised or lowered. In its lowermostposition the Weight of theplatform K is borne by suitable m eans-it may be the chains L connected with the hangers L, as shown in Fig. 2. hile the platform may be adjusted up or down on the hangers L in various ways and secured in any desired adjustment by various devices,- I prefer the construction shown, and which I will now describe. In this construction belts M are secured at their outer ends to the hangers L, extend thence under suitable guides K on the platform K,and connect with suitable operating means whereby the belts may be tightened or drawn upon to elevate the plat form K or may be slackened to permit the said platform to lower to any desired degree. As shown, I employ a stand N, mounted upon the platform slightly to one side of the center and having the lower guides N and the upper guides N over which the belts M pass and connect with the treadle 0, so the latter may be depressed to elevate the platform K or released to slacken the belt and allow the platform to descend. 'In connection with the treadle and belts I employ detent devices for holding the treadle in anyadjustment to which it may be depressed. To this end I provide racks P in the stand N, which racks are engaged by pins 0 on the treadle O,such treadle being arranged to rock, so its lower end, which bears the pins 0, may be set to any desired position to adjust such pins 0 into and out of engagement with the racks P. It will be noticed the racks P are Further, the grip-sleeves J may be held in the hands of the operator;

, insO' into and out of en a ement with the D c z:

racks P.

Now in operation the treadle may be engaged with the foot by putting the latter in the loop 0 of the treadle, when if the platform be down the treadle will be elevated and the operator may press the treadle down in the stand N to any desired degree, such movement of .the treadle operating to elevatethe platform. If now it be desired to lower the platfomn, {the treadle may berocked by the foot to the dotted-line position shown in Fig. 9, when the weight of the platform will cause the same to readjust itself to its lowermost position, such operation being aided whenever necessary .by the pressnreof the other foot of ttheioperatoron the said platform.

I prefer to provide casingsiQover that portion of the belts which extends between the stand N and the upright portions K at the sides of the platform.

While I have referred itO the parts M as belts,.it should beiunderstood that I intend to include in such term any suitable flexible devices which may be adapted .or suitable for the purposes of such parts as before described.

In Fig. 1 and in detail, Fig. .5, I show a brake device comprising a plate R, extending rearwardly from the platform K, so it can be pressed bythe foot of the operator upon the ground to brakethe velocipede. This is done by the-rider stepping on and thusapplying superior pressure to the rear portion of the platform, so that the latter swings forward, it being held thus tilted at a slight angle until the rider steps forward and stands at or near its center. The .plate R is preferably of spring metal, fitting at R over the head at the rear edge of the platform K and having the forwardly-projecting bail R held by the bolt R to the. platform. This brake is simple in construction, can be quickly applied, and can be readily renewed when desired.

It may be desired in some instances tocounterpoise the platform, to which end I have provided a weight S, having a stem S heldin guides S on the platform,as shown in Fig. 1.

By the described construction it is evident the platform may be raised or lowered to suit the height of the operator and also to accommodate the machine to stones or other obstructions upon or conditionsof the roads on which the machine may be used.
