SPECIFICATION forming part of Letters Patent No. 380,168, dated March 27, 1888.

Application filed December 27. 1887. Serial No. 259.181. (N model.)

To all whom it may concern.-

Be it known that I, JOHN BLASDALE, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Locomotives, of which the following is aspecification.

My invention relates to that class of locomotives which are employed in lumbering regions and similar places, where the temporary IO track consists of poles or rough wooden stringers, which are rough and uneven. It is desirable in this class of locomotives to allow the driving-wheels to have a free lateral movement independent of each other.

The invention is fully illustrated in the accompanying drawings, in which- Figure 1 is a side View of a locomotive provided with my improvement. Fig. 2 is a plan view of the frame, showing the part relating to the invention. Figs. 3and 4 are side and top views, respectively, of a driving-wheel, master-shaft, and connecting-rod. Fig. 5 is a diametrical section of a driving-wheel and its connections. Fig. 6 is an inner side view of a driving-disk. I The letter A designates the frame; B, the driving-wheels, which may or may not have grooved rims a. The frame rests on vertical pedestals C, and the axle-boxes c fit in the pedestals and may move therein vertically. A spring, (1, is interposed between the frame and each axle-box. The wheels B turn loosely on the axle, and also have lateral movement endwise of the axle.

The axle-boxc is provided with an extension or sleeve, 0, which surrounds the axle e, and projects outward similar to that shown, described, and claimed in Letters Patent of the United States No. 367,335, granted to ine July 26, 1887.

A driving-disk, E, is mounted to turn loosely on the axle, and has position on theend of the axle outside of the wheel B. This driving-disk may be confined from coming off in any suitable way by a collar or plate, for instance, made fast to the end of axle. The drivingdisk turns, but has no lateral movement on the axle.

My invention consists of a flexible connec 50 tion between the driving-wheel B, mounted on the axle or on the sleeve 0, so as to have lateral two parallel bars.

movement endwise of the axle, and the driving-disk E, mounted on the axle, but immovable laterally or endwise of the axle. The flexible-connection in the present instance consists of the links h, one end of which is jointed at h to the driving-wheel B and the other end jointed at h to the driving-disk E. The link h may consist of a single bar, or, as shown, of

B; but three or four might be employed, if desired. .The particular construction here shown for joining the links consists of two eyebolts, z, secured to the wheel, and-two earsflc, secured to or cast on the disk. The link-bars h are then jointed, as already stated, to the said eyebolt and ear. Motion imparted to the disk E will (See Fig. 6.) Two links h are used to connect each disk E with a wheel,

cause the driving-wheel B to revolve. on the axle e, (or, as it is in the present instance on the sleeve c,) and at the same time the linkconnection will allow said driving-wheel to have play or movement in a direction endwise of the axle. This movement is indicated by broken lines on one'of the wheels B in Fig. 2.

The extension or sleeve 0, attached to the axle-box c, and on which the wheel B revolves, is not necessary to my present invention. I show it, however, and it is slightly modified in form from that shown in my patent aforesaid. In this instance the said sleeve 0' extends toward the end of the axle far enough to receive a part only of the thickness of the hub of the driving-wheel B, and the drivingdisk E, as here shown, has a similar sleeve, 0 which enters the hub of the wheel B and meets the axle-box sleeve of. Therefore the drivingwheel B, as here shown, revolves on the axlebox sleeve 0 and the disk-sleeve 0 Both of these sleeves may be dispensed with.

I may also state that my invention of the flexible or link connection may be used with the driving-disk E, revolving loosely onthe axle or fixed tight thereon. In the presentinstance it is loose.

A master-shaft, D, is suitably mounted onthe frame A, intermediate of the front and rear driving-wheels, B, and has at each end a crank, F. Each of the driving-disks E is provided with a crank-wrist, Z, and a connecting-rod, G, connects the said driving-crank F with each crank-wrist l.

ICO

desire to secure by Letters Patent of the United States- 1. In a locomotive, the combination of an axle, e, driving-wheels B, which have movement endwise of the axle, a driving-disk, E, on

the axle immovable in a direction endwise of the axle, and a flexible connection between the said driving-wheel and driving-disk, whereby rotary motion imparted to the driving-disk will revolve the drivingwheel and allow the latter to move endwise of the axle.

2. In a locomotive, the combination of an axle, e, driving-wheels B, which have movement endwise of the axle, a driving-disk, E,

on the axle immovable in a direction endwise 2 5 of the axle, and one or more links, h, connecting the said driving-wheel and driving-disk,

said links having one end jointed to the driving-wheel and the other end jointed to the driving-disk.

3. In a locomotive, the combination of a master-shaft, D, provided with a driving-crank, F, an axle, e, driving-wheels B, which have movement endwise of the axle, a driving-disk, E, on the axle outside of the driving-wheel, immovable in a direction endwise of the axle, and provided with a crank-wrist, l, a flexible connection between said driving-wheel and driving-disk, and a connecting-rod, G, be-- tween the said driving-crank F and crankwrist.

In testimony whereof Iaffix my signature in presence of two witnesses.

JOHN BLASDALE.
