IMPROVEMENT IN WRENCHES.

Specification forming part of Letters Patent No. 146,254,V datedJa'nuary 6, 1874; application filed June 18, 1873.

Vsh all be more rapid, powerful, and convenient in its operation than those heretofore made or known 5` and consists, first, fof an oscillating lever and a socket for embracing a nut, incon- .neetion with certain ratchets, pawls, and cogwheels, so arranged that both the forward and backward oscillations of the lever cause the socket to rotate in the same direction, all suital'ilymounted in aframe and adapted to be used upon a rail or Vrails for turning nuts upon Vtrack-bolts; second, in so constructing the ratchet and' cog wheels, and arranging them in relation to the lever and the socket for embracing the nut, that the movement of the lever in one direction will impart to the nut a slow, powerful movement, a-nd the movement of thelever in the opposite direction will impart to the nut a more rapid but less powerful movement in the same direction; third, in the construction and arrangement of the socket for embracing the nut in a case so constructed and arranged in relation to the other parts of the machine that the socket may be adjusted,

l and applied to, and removed from the nut while the other parts of the machine are at rest upon the `rail 5 fourth, in so constructing and adapting to a rail a wrench for turning nuts upon track-bolts that it may be easily and conveniently propelled along and upon the rails from bolt to bolt, and from joint to `joint, and stopped, and thereby made secure to the rail while turning the nut; f1ftl1,in a

clamping device for fastening the wrench to j the rail.

Figure 1, in the accompanying drawings, is a side elevation of my invention attached to the rails R, which are connected bythe splicebars S, which are held in place by the nuts n u n n. Fig. 2 is a plan. Fig. 3 is a partial `rear elevation, showing the clamping device. Fig. 4 is the socket-wheel, shown in detail, A being a front elevation, and a a side elevation. Fig. 5 is a front elevation of the ease in which the socket A has its bearings, and alsoa partial view of one ofthe wheels which conveys cog-wheel C, with the ease B, carrying the socket-wheel A, is placed upon the shaft b, Fig. 2, which has its bearings in the fralneK,` The construction at this' point issueh that the case B, with itscontents, may be movedlaterl ally in relation to the frame K and other parts, for the purpose of placing it in position on the` nut and relu oving it therefrom while the other parts of the machine are at rest uponthe`rai1, and it is also free to move in a rotary manner around or partially around the shaft I), for the purpose of adjusting the socket vertically to the varying position of the nuts on idifferent rails, and also to admitof swinging the case and socket into the space P, Fig. 2, when not in use. A cog-wheel, E, having upon a por-` tion of its periphery a double Iset of ratchetteeth, facing in opposite directions, 12, Fig. `2, iswso placed on a shaft in the frame K that its cogs will engage with those of the wheel C when the socket-wheel A is in position for turning the nut. to the wheel E, but differing therefromin this, that the portion of its. periphery having cogs is smaller in diameter,` is placed opposite it, and between them is placed the lever D, Figs.v

1 and 2, bearing upon Vits sides the double pawls l and e, which engage alternately with the wheels E and F as `the lever D isoseillated on its fulcrum, which is concentric' withthe` wheels E and F. A shaft, h, is provided, on which is fastened the cog-wheel I, which engages with the wheel E, and the cog-wheel H,

which engages with the wheel F through the intermediate wheel G. `A crank, m, is attachedv tothe shaft h, by means of which the nut may be turned without the use of the lever Dwhen but little power is required. The wheels Jj, :having flangeswhieh projecten each side of the rail R, are placed on suitable shafts in the frame, and serve to support and keep the ma- Another wheel, F, similar chine in position on thc rail, and also provide a means for moving it easily along from joint to joint and from bolt to bolt.

It is obvious that wheels without flanges might be used, and the flanges or guides attached to sonic other part of the machine, as the frame; or the wheels might be dispensed with altogether, and the machine, held in position and guided by the flanges, or their equivalent, might be,slid along upon the rail; but I-prefer the method here shown.

A clamp for fastening the machine rmly to the rail While turning the nuts is attached to the rear end of the frame K, or in any other suitable position; and consists of the jointed levers L, Figs. 1 and 5, connected at their longer ends by the notched bar c, to which the cam-lever f is attached. A spring, 3, Fig. 2, serves, by contact with the head of the track-bolt, to keep the bolt from being pressed out, when the socket is applied to the nut, and also to indicate, by its position on the head of the bolt, when the machine is in proper position for stopping it in its passage along the rail.

The manner of operation is as follows: The wrench or machine having been placed upon a line of rails, it is run forward upony the rails until the spring 3, Fic. 2, comes in contact with the head of a track-bolt. The long arms of the jointed levers L are then. brought toward each other, which closes the short arms or jaws upon the rail'. The notched connecting-bar c, Fig. 3, is then slid along through the slots, in which it rests until the cam-1ever f, presenting the thin side of its cam, is brought against one long arm, and one of the notches drops over a projection on the other. The cam-lever is now pressed down and the jaws are drawn forcibly together on the rail, thus fastening the machine securely to the rail. The case B, with its socket-wheel A, is now swung down out of the opening P, where it had rested, and is moved laterally until the socket embraces the nut, which is upon the bolt, and the cog-wheel C engages the wheel E, where it is held by the cap o dropping down over the end of the shaft b. The lever l) now being moved in one direction, the pawl e engages one of the ratchets in the wheel F, carrying it with the lever, and thus giving, with great power, through the connectingwheels and socket A, a slow rotary motion to the nut. In moving the lever D in the opposite direction, the pawl l engages one of the ratchets in the wheel E, vcarrying it with the lever, and thus revolving the nut in the saine direction as before, but with increased speed and less power, thus giving an alternate slow and fast motion to the nut, and enabling the Operator to turn the nut on or off quickly, and

also giving him power to force the nut'ovei rough places on the bolt, and to set it firmly to its bearing. This is accomplished in the following manner: Whenever a rough or uneven. place in the threads, either of bolt or nut, is encountered in turning the nut off or on the bolt, or when the nut comes to its bearing, the rapid motion may be dispensed with at will by raising the pawl d out of connection with the ratchet on E, and using as long as may be necessary the slow powerful movement.

When two nuts are used on one bolt, as is mostfrequently the case, after theirst nut has been turned onto the bolt so far that the end of the bolt projects slightly through the nut, the second nut is introduced into the socket and turned on at the same time with the rst. Vhen the first nut comes to its bearing, it becomes necessary to turn the second nut without turning the first, in order to set it firmly against the first. This is accomplished by moving the socket and its case laterally away from the first nut until the socket will revolve clear of it. It is retained in this position by the cap o falling into a groove in the shaft b, and the second nut is then revolved, by the same means as before, until it sits firmly against the rst. By reversing the position of the pawls d and e-that is, by turning them over, the other side up--they will engage with the sets of ratchet-teeth on the wheels E and F which were before idle, and the same motions of the lever which before turned the nut on will now turn it off the bolt.

What I claim as my invention is- 1. The laterally and vertically adjustable case B, provided with the cog-wheel A, having a nut-orice, and the cog-wheel C, substantially as and for the purposes set forth.

2. The combination of the cog-wheels E F, both having a double row of ratchet-teeth, facing in opposite directions, and mounted upon a shaft, with the lever D, reversible double pawls d e, and the wheels O A in the suspended case B, all substantially as and for the purposes set forth.

3. The combination of the frame K and the front and rear flanged wheels J j, or their equivalents, supporting a mechanism for'turning nuts on a railroad-rail, as set forth.

4. The combination, with the frame K, of the pivoted cross-levers L L, notched connecting-bar c, and cam-lever f, for holding the movable frame and its nut-turning mechanism rigidly to the rails, substantially as set forth.
