IMPROVED VELOCIIPEIDE.

The Schedule referred to in these Let ers Patent and making part of the same.

To all whom t ina/y concern Beit known that we, (l. J. Dorr and Ani-nen S. DCKRvSON, of 'Vashington, in the county of Washington, and District of Columbia, have invented a new and useful Improvement in Velccipedes; and we do hereby declare that the following is a full, clear, and exact description of the saine, reference 1oeing had to the annexed drawings, making part ci this speciiication, in which- Figure 1 is a tcp or plan view oi' our velocipede, and

Figure 2 is a longitudinal vertical section on line x a: of iig. 1.

Corresponding letters refer to corresponlling parts in both igures.

This invention relates to an improvement in that class of devices denominated three-wheeled velocipedes3 and It consists in the combination and arrangement of the part-s of which it is composed, as will be more fully described hereafter.

A, in the drawings, represents a portion ofthe framework of the machine, the rear endsgof which are attached tothe rear axles B, from which part it extends forward for any required distance, when it is so bent as to ext-end transversely across the machine. A

B represents the rear axle, which is of the curved form shown in fig. l.

To this axle the two rear wheels ofthe machine are fitted. v

C O represent 'the wheels above alluded to, and

D represents the forward and guide or steeringwheel. p

E represents an axle, which has its bearings in th front, ends of the frame K, and to which the guidewheel is attached.

F F represent cranks, which are secured to the ends of shaft, or axle F, as clearly shown in iig. l.

G Grepresent connecting-rods, which extend from cranks F F to the upper and. lower ends of lever H, and are for the purpose of communicating the motion of such lever to the .cra-nhs, i'or propelling the device.

H represents a jointed leve-r, whiclnis pivoted to the spring-bars 1 I, ata-point just above the joint in the saine. The upper end is provided with handles on either side thereof, and also with the means of attaching to the'same, the connecting-rod G, which extends from thence to crank F'.

The lower arm of this lever is jointed to the arm above described, its lower end being provided with projections, upon which the operator can place his feet when operating the machine, and it is also provided with the means of attaching thereto the connectingrod G, which leads therefrom to crank F of the driving-shaft F.

l I represent spring-bars, which are attached to the end of frame K, in front of the bearing of shaft E, in

order that as much as possible of the weight of the operator may be thrown upon the drivingewheei of the machine. From the point of junction with the frame K, these bars extend, in an inclined direction, to a point in the rear of the jointed lever, suihciently great to secure the semicircular plate L, which joins their rear ends together.

'K represents a frame, or yoke, which is pivoted centrally to the front end of frame A, so that as the guidewheel is turned, to give direction to the machine, this frame may turn with it. In the forward ends of this frame are secured the boxes which hold the journals of' the driving and guide-wheel.

L' represents a plate, of metal, which is secured to the rear end of the spring-bars, and which unites them together. This plate also serves as a seat for the op erator, or as a device to which such seatV may be attached, and ais' as a support for the series of sheaves, or wheels around which the guiding or steering-rope passes.

M M' M?t represent wheels, or sheaves, around which the rope, or chain which controls thedirection of the machine passes. These sheaves are provided with a groove in their peripheries, for the rope, or chain to lie in.

It will Vhe observed that the wheel h is larger in diameter than the remaining ones, and that it is provided with a handle, and also that the rope, or chain passes .entirely around it.

This arrangement is for the purpose of causing it to be used as the means of giving direction to the machine by being manipulated by the operator, as he sits upon his scat, he using one oi' his hands for that purpose, while aiding in propelling the machine with the other; and at the same time he is enabled to apply a considerable amount of power by means of the lower arms of lever H and rod G, which may be operated with his feet. y

N representsa rope, or chain, which is to be secured to the staples a c, fixed in the frame A, it passing cntirely around wheel M", and behind or outside of wheels M and M', as clearly shown in fig. l.

` Having thus described our invention,

What we claim, and desire to secure by Letters The arrangement of the cranks F F', connectingrods G G', and jointed lever H, -with reference to the steering-apparatus, substantially as and for the purpose specified.

In testimony whereof, we have signed our names to this specication, in the presence of two subscribing witnesses.
