To all whom it may concern:
Be it known that I, THEODORE T. YVOOD RUFF, a citizen of the United States, residing at Philadelphia, in the county of Philadelphi-a and State of Pennsylvania, haveinvented certain new and useful Improvements in L0- comotive-Engines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable :0 others skilled in the art to which it appertains to make and use the same.
This invention relates to locomotives, and particularly to the driving mechanism thereof.
The object of the-invention is to produce a driving mechanism whereby an equal number of foot-pounds of steam can be applied to the driving-wheels either at the minimum or at the maximum speed of the locomotive. Furthermore, the object is to produce a reliable 2o driving mechanism whereby the drivingwheels receive motion in such manner as to lessen the danger of Slipping and to render their respective speeds equal without the use of parallel rods. Furthermore, the object is to z 5 produce a device for imparting motion to the driven-heels, which shall be so. constructed as to render the change froma slow to a'fast n1otion easily accomplished.
Vith these objects in view my invention consists, essentially, in a driving-gear for locomotives, comprising drive-wheels. having their axles provided with toothed wheels, adrivingshaft mounted between the drive-wheels and provided with pinions meshing with the said toothed wheels, the pinions upon opposite sides being of different diameter and number of their cogs, and mechanism for applying the friction-coupling of the driving-shaft to the.
pinion upon it, which will transmit motionto the driving-wheels of the motor.
I'have illustrated the invention in the accompanying drawings, in which Figured is a plan view of my driving mechanism. Fig. 2 is a horizontal section thereof.
' 5 Fig. 3 is a side elevation showing the driving mechanism, with the boiler, &c., of the engine removed. Fig. 4 is a side elevation, partly In section, showing the drive-wheels, the
boiler, and a part of the mechanism whereby.
the shifting of the driving-gear is accomplished. Figs. 5, 6, 7, 8, 9, 10, 11', 12, 13, and l4 represent details of construction.
In the accompanying drawings, A representsthe driving-wheels of a locomotiveengine, and B represents the axles thereof. 5 5
E represents. a frame provided with depending portions L, whichrest upon the boxes of the drivingwheels. Upon each of the axles are placed two gear-wheels, 00, of different -diameters and numbers of cogs.
G represents a driving-shaft, which is placed centrally between the drivewheels, and is pro- .vided with a crank, F, at each end, through which motion is imparted to the drive-shaft from the pistons of the cylinders,'which are not shown. There are two cog-wheels, D D, i which are termed pinions, placed upon the driving-shaft, one near each end, and so arranged as to gear with the cogged wheels upon the axles of the drive-wheels. are fitted to revolve freelynpon their local sections against the collar S on the drive-shaft. Each of the pinions is so arranged relative to the cogged wheels upon the axles of the drivewheels as to gear with the cogged wheels with 7 5 each of the axles; and inasmuch as the diameter of the cogged wheels on different sides of the locomotive are different, the speed of the 1 drive-wheels may-be regulated by gearing the driving mechanism with" different sides, and in order that the speed may be changed'readily and at will, I provide means, which will be hereinafter clearly described, for coupling one of the pinions to a driving-shaft and for uncoupling the other pinion; or both may be uncoupled at the same time.
The pinions are fitted to revolvefreely against their respective collars, S, upon the driving shaft, and they are provided with means of rigidly coupling either one of the said go pinions D D to the drivingshaft G, so that when the crank or driving shaft is forced to revolve either of the pinions which may be coupled to the said crank or driving shaft will transmit force and motion to its fellow spur- 5 wheels 0 and G, which are made rigidly fast to each of their respective axles, B and Bi Upon the driving-shaft G there is placed a sliding friction-coupling cylinder, H H. The
The pinions 70 annular shell thereof and the piston O are made esaoas in two sections. The two sectionsdf the piston,
- ,which must revolve with the said The two sections H H of the said with their hemp packingrings Qupon them, are placed centrally between the two pinions D D, upon the driving shaft, where the two sections Gare made firmly and'rigidly fast to the drivingshaft and become as one piston,
shaft G. cylinder willbe coupled togetherover the pis- 10 ton by a series of bolts, as at]? P. The two same.- The hubs of the cylinder-heads extend heads N and N of the cylinder-are fitted 0 their local places upon the driving-shaft, that they can readily slide back and forth on the into a recess in the piston upon their respective sides of the piston, each of which are provided with hemp packing-rings Q, by which the said hemp packing will be set and held in its place bya series of bolts through the flanges of the said packing-rings Q.
the disks of the piston.
Each of the two cylinder-heads N and N are coupled to the piston on their respective sides by a series of alternate projections and recesses upon the disks of the cylinder-heads and upon The projections and recesses are arranged concentric with the driving-shaft G, each of which occupy alternate spaces between lines radiating from the center of their revolving motion, so that the pro- Q jeetions uponv one of the parts will correspond said cylinder H and H with all of its parts is' made to revolve with'the said crank or drivwith and enter into the recess of its fellow, and in this way coupling the two heads to the piston so far as relates to rotary motion. By the above described means the coupling of the ing shaft, and at the same time is allowed to slide longitudinally upon its piston and upon the driving-shaft without uncoupling either-of 40 the cylinderfheads from thepiston. The annular opening between the two sections of the piston and cylinder is for the purpose of reach in g the packing-bolts.
0n eachof the two heads of the cylinder H and H t ere is a series of'Vshaped annular the grooves of its fellow coupling. Thus when the two pieces are brought together the surfaces of the flanges of one piece will cor respond with and fit to the surface of the grooves of their fellow couplings. When force is applied, the annular flan will bewedged one into the other, and constitute a firm revolving coupling.
7 shaft G is supported and held in position by a truss-hanger, T, at each endthereoi} the ends of thehanger being. adjusted torest upon the journal-boxes of the axles at .L. I
Upon the steam-boiler V; there is mounted a steam oil-pump, .with its cylinders A and B resting 'upon their supports W, which are sccuredto the oiler, the cylinders being cut through longitudinally on a vertical plane of 'riesof bolts, G.
provided with' the ordinary ges and grooves- The 'crank-' their centers. The steam and oil cylinders are each rigidly coupled'to the other by a se- The two pistons C and D are each upon the same rod E, and the pistonrod is provided with the ordinary stuflingboxes, at F, as shown. The steam-cylinder is sliding-valve steam-chest I, with valve-rod J with valverod support X, and valverlever Y, steam-inthrough the oil-ports R and Rintothe couplingcylinder. (See'Figs. 2, 4, 7, and 8.) There. will be a metallic wrapper, M, around the I annular opening between the two sections of the pistons O and cylinder H and H.
Since I have so fully described the mechanism of my invention, I may make it more clearly understood by describing its operation.
The engineer, by a movement of the hand lever, Y, admits steaminto the steam-pump cylinder A, which operates upon the oil-piston D, which is upon the same rod E, and forces the oil from'on'e of-thc oil-chambers of the pn mp-cylinder outthrough one ofthe oil-pipes,
. J, and through its coupling-box J and oil-port it into one of the chambers ofthesliding cylinder H H, and slides the cylinder longitudinally over the piston upon the drive-shaft and carries the annular flange and groove coupling into forced contiguity, which couples the drive shaft G to one: of the pinions D, which' then is the dominant when the opposite pinion may run loosely upon the drivingshaft. 4
ling from one driving-pinion to the other, the engineer will throw the valve-lever Y over To change the coup There are also or driving pinion;-
and admit steam into the cylinder A upon the v opposite side of the piston G, which will reve'rse the oil-pump piston D and force the oil from the other chamber of the pump-cylinder throughits train of pipes into the chamber of thesliding cylinder, which will, force the cyl- .inder awayifromf its first coupling into coup,-
ling-with the other pinion upon thedriveshaft, when it becomesv the dominant or driving pinion, all of which is produced by one thrust of the steam-pump, either when the motor is at a stand or running upd'n the rails. The oil or other fluid employed as theagent of force in the steamp-pump isin separate chambers, andis pumped back andiforth upon their respective sides of the piston.
Having thus fully described myinvent-ion,
what I claim, and desire to secure by Letters Patent, is-
tially as described.
