“_A_ represents the hind axle, whereon the two hind wheels, _B_, are fitted by means of the well-known rose-clutch device _C_, the frame _H_, and turned by hand-cranks _I_, to be worked by the operator, who sits upon the saddle _J_. “We have also arms, _Y_, for the application of the feet of the operator to steer the vehicle, while the lever ranges rearward towards the operator for being conveniently worked by hand. “The construction is very simple and cheap, and the arrangement is calculated to afford a convenient and easily-operated hand-power vehicle.” * * * * * Messrs. Hull and O’Rear find that it is better to steer with the feet and propel the machine by the arms. The rider is peering anxiously forward as though somebody was ahead of him, and he appears rather disconcerted from some cause; which makes us think the picture has been taken from real life.

Patented January 8, 1884.] SCHAFFER SPECIFICATION. “The object of my invention is to furnish a safe and convenient velocipede of the unicycle type; and to that end my invention consists in certain novel features of construction and arrangement, as hereinafter described and claimed. “The operator may stand erect, and in order to obtain the necessary vertical space without too large a wheel the rim or felly is made of considerable width, as shown in Fig. 2. With this wide tire the wheel will stand without support, and I prefer to use a recessed tire or two smaller tires, as shown, between which is a rubber or elastic band to prevent concussion and noise. “To allow of entering the machine, a portion, _c′_, of one felly is made separate, and the hub _a_ made with a hinged segment, _a²_, to which the spokes from the felly-segment _c′_ connect, so that the latter can be swung out.” * * * * * Mr. Schaffer does not seem to have provided any very ready means of escape for the bird in case the cage should run away or collide with another.

Patented June 3, 1884.] BURLINGHAUSEN SPECIFICATION. “My invention relates to improvements in one-wheel velocipedes; and it consists in certain features of construction and in combination of parts hereinafter described, and pointed out in the claim. “As the operator must sit some distance back of the axis of the wheel, some force is required to support or balance the seat and operate in the required position, and this is furnished by the sliding weight _H_ secured by a set-screw on the rod _G_. “What I claim is,—
