TRACTION-ENGINE.

SPECIFICATION forming part of Letters Patent No. 302,841, dated July 29, 188

Application filed April 528, 1854.

To all whom it may concern:

Be it known that I, ADAM H. HAFLEY, a citizen of the United States, residing at Ashley, in the county of \Vashington and State of Illinois, have invented certain new and useful Improvements in Traction-Engines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure 1 of the drawings is a perspective view of my traction-engine. Fig. 2 is a vertical sectional view of the same. Fig. 3 is a vertical sectional view of the cylinder, steamchest, 8:0. Fig. 4. is a detail view of the steering mechanism, and Fig. 5 is a transverse sec tion of one of the lantern-wheels.

This invention has relation to improvements in traction-engines; and it consists in thenovel arrangement and construction of devices, as will be hereinafter fully described, and particularly pointed out in the claims appended.

In the accompanying drawings, the letter A represents an upright boiler.

F is the steam-cylinder, and G the steamchest; H, the piston; H, the pistonrod; J the valve-rod; and J is the sliding valve, which may be of any approved construction.

To the outer end of the piston-rod H are secured narrow iron plates 1). These plates are secured at their ends to blocks 2/, which are secured to the vertical guide-rods I I in such a manner as to leave a slot, 0, between the plates, and in said slot is placed a tubular or hollow shaft, 0, capable of sliding in the slot. The guide-rods I I move vertically in the boxes 2, these boxes being secured and connected by the cross-pieces cl (1. The plates 1) Z) are inclosed between the two wheels K, which consist of two circular solid disks centrally secured to a horizontal shaft, M. These wheels are connected at points near their circumference by a pin, which passes through an aperture in the center of the tubular or hollow shaft 0. The pin 12 fits so closelyin the shaft 0' as to cause no jarring, but not so (No model.)

closely as to cause much friction. iy this construction, as the piston-rod ascends and descends, it will, through the wrist-pin,\ vhich will slide back and forth in the slot 0. impart rotary motion to the wheels K. The lanternwheels N, whose cogs engage the teeth of the wheels L L, turn loosely on the shaft M at its extremities. The wheels N are made to rotate by mechanism hereinafter to be described.

The wheelsL L are secured to the spokes of the rear wheels, 0 O, of the carriage by outwardly-curved pieces, the centers of the wheels L L being in the axis B of the wheels 0 0. Each of the lantern-wheels N are provided on each of their faces with ai'lange, j, extending around their circumference, so as to leave a recessportion in each face. The innersides of these flanges are provided with ratchetteeth, which are inclined in opposite directions. The circular plates A are keyed to the shaft M and rotate therewith.

In the recessed portion of the face of each wheel N are situated, above and below the shaft two pawls, c 0, adapted to engage'the teeth in the recess of the wheel N. I These pawls pass through slots in the plates A, and are pivoted at their outer extremities to links 1 y, thelinks being hinged at their farther endsto a collar, (1", fitted to the shaft, and capable of being moved in the direction of the length of the shaft.

Between the pawls c c and the hubs 011 the plates A are springs c, which are designed to throw the said pawls in engagement with the teeth of the wheel N.

Arranged loosely upon the horizontal portion of the pawls c c are grooved rings f, in which the shifting-rod is free to rotate. To these rings are loosely secured the vertical rods j j, having forked ends, the pairs being situated on opposite sides of each wheel, and connected above the lantern-wheels N by a cross-bar, 1. At the middle of this crossbar is pivoted the lever 0. This lever is similar to the reversing-lever of a locon1otive, and is pivoted, as at pivot a, having its lower end forked to engage a pin on the bar Z, and is capable of being set in any one of three positions by means of the circular are q, provided with three notches, s s s, and the dog p, adapted to fit in these notches. When the lever is set at s, the pawl on the right of the trundle-Wheel will engage in the teeth of the flange, and if the shaft is rotating in the proper direction the motion given to the pawl will be transmitted to the trundle-wheel N, and through it to the wheels of the carriage. When the engine is reversed and the carriage-shaft M is turned in the opposite direction, the lever 0 is set at s, and the pawl on the left of the trundle-wheel is thrown into engagement with the teeth on the opposite side of the wheel N. These teeth being inclined in the opposite direction to those on the right of the wheel, they will transmit the opposite rotary motion of the plates A to the trundle-wheel N. When the lever o is set at s, none of the pawls c 0 are in engagement, and the engine maybe used for driving other machinery.

Between the crank-wheel K and the lantern-wheel N is centrally fixed on the axis M the small wheel Q,'whose teeth engage the teeth of the wheel 1?, turning on. the axis B. This wheel has a bevel-pinion, S, on its outer face, whose teeth engage the teeth of two bevel-wheels, T T, which turn loosely on a shaft, Z. This shaft projects forward to a point above the guide-wheel U, and terminates in an endless screw, Y, whose thread engages the teeth of the horizontal wheel V. The axis of the wheel V is secured to the cross-piece 2, connecting the supports X X, which pass down on each side of the wheel U, so that when the toothed wheelV is turned the guidewheel U will be turned with it. The shaft Z has fixed at its rear a vertical wheel, f, having a handle, h, by which means the wheel V may be turned by hand, and with it the guidewheel U in either direction. By means of the bevel-wheels T T and connected gearing and levers, the guiding may also be done by steam. Two clutches, n n, capable of sliding on the shaft Z, and provided with collars t 23 may be thrown in or out of engagement with the corresponding clutches, m m, on the wheelsT T by mechanism hereinafter to be described. The portions of the shaft on which the clutches a n slide are polygonal in cross-section,so that when one of them is in engagement with the corresponding wheel the rotation of the wheel will cause the shaft Z to turn, and through the connected mechanism will turn the guide wheel one way or the other, depending on which clutch is thrown into engagement with those on the wheels T T. These clutches are thrown into engagement by means of the rods 70, forked at their lower ends, the fork fitting over the collars tv t and pivoted to the lever q, which is pivoted at s. The lever is similar to the reversing-lever of a locomotive, having a spring-dog which is capable of set in any one of the three notches mm 00, provided at the rear portion, the middle. and the forward portion of the circular arc is, so that the levermay be set in either the first or last of these positions, and either of the clutches be thrown into engagement with its adjacent wheel. When the lever is set at the middle notch, 00, neither clutch is in engagement, and the bevel-wheels T T turn loosely on the shaft Z without imparting any motion to it.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination, with the trundlewheels N, turning loosely on the shaft M, and provided with flanges j, and recesses in the sides, said recesses being provided with ratchet-teeth in contrary directions on the opposite faces of the wheel, of the circular plates A, keyed to the shaft M, the pawls c 0, links 3 y, collars d fitting loosely on the shaft M, slide collars f f, bar L, having forked ends J, and lever 0, substantially as and for the purpose set forth.

2. The combination,with the wheel Q, fixed on the driving-shaft M, of the wheel P, having a bevel-pinion, S, and two bevel-wheels, T T, turning loosely on the shaft Z, and having clutches m m on their outer faces, of the clutches n, which rotate with the shaft Z,endless screws y, wheel V, and the mechanism for throwing the clutches n in and out of engagement with the clutches m m, consisting of the rods pivoted to the lever q, substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

ADAM H. HAFLEY.
