SPECIFICATION forming part of Letters Patent No. 776,994, dated December 6, 1904.

Application filed Tune 15, 1904. Serial No. 212,634. (No model.)

T0 all whom, t 71u14/ concern:

Be it known that I, DANIEL BRENNAN, J r., a citizen of the United States, and a resident of Havel-straw, in the county of Rockland and State of New York, have invented a new and Improved r1`raction-'1`rain, of which the following is a full, clear, and exact description.

The invention relates to an organism of elements in an engine and one or more wagons or vehicles, enabling the| engine to propel the vehicles in either direction and the entire train to be guided as desired.'

The invention also relates to certain special features of construction and arrangement of parts for attaining the end referred to.

lt has been proposed heretofore to provide a traction-train-. e., an arrangement of engines and wagons in such a Way that thetrain may bo propelled forward or backward and steered. The steering, however, has been iniperfectly attained, since with the mechanism heretofore devised the train was forced to approach and leave a curve on tangents, the running from one curve directlyinto a reverse curve being impossible without skidding the wheels, which of course is not practicable.l especially in the heavy work to whichV my invention is particularly adapted. By the arrangement which 1 have provided the control of the train is perfect, the steering being possible either from the end Wagon or from the engine itself and the train being movable either forward or backward, respectively, by the pushing and pulling actions of the engine. 1 attain this result by providing the exigirle with an axle arranged to swing to steer the engine and the swinging axle carrying with it an outwardly-projecting member adapted to have pivotal connection with the adjacent wagon. The wagons are provided with swinging axles to enable them to be steered, and said wagons having such interconnection as will cause the one to follow the movement of the wagon preceding it and the whole being controlled by theoperator, who imparts initial steering action to one of the wagons or to the traction-engine, as the case may be. By this mechanism the train may be advanced either forward or backward and the whole of the elements of the train caused to follow the various turns and other movements of the leading wagon or engine, according to whether .the engine is operating the train by pushing or pulling thereon.

Referenceis had to the accompanying drawings, which illustrate as an example one embodimentof my invention, in which drawings like figures of reference indicate like parts in the several views, and in which- Figure 1 is adiagrammatic plan View showing one traction-engine and three wagons and illustrating a possible position of the train in which the engine is pushing the wagons and is approaching a curve, the first wagon on the curve, the second wagon in reversing position-that is, with the wheels of one axle running in an arc reverse to the arc in which the wheels of the other axleare running-and the third wagon running in a straight line. Fig. 2 is an enlarged plan view showing the forward portion of the running-gear of the traction-engine and illustrating the swinging axle and also showing the running-gear at one end of one of the cars or Wagons. Fig. 3 is an enlarged side elevation showing the front part of the traction-engine and one end of one of the wagons with the traction-engine-steering axle and the axles of the Wagon in section on the line 3 3 in Fig. 2 to show the details of the preferred equipment. Fig. 4is afragmentary front elevation of the traction-engine boiler with the bolster, axle, and adjacent parts in transversesection on the line44in Fig. 3. Fig. 5 is a front elevation, with parts in section, on the line 5 5 of Fig. 3, of one of the wagons, showing the swinging axle and the connected parts; and Fig. 6 is a plan view showing the manner of preventing the Wagonwlieels from tracking.

Referring particularly to Fig. 1, 10 `indicates the body of the traction-engine, having its traction-wheels 11 mounted on anon-swinging axle, as usual. The steering or pilot Wheels 12 are mounted on an axle 14, which swings around aking-boltl. The Swingin" movement of the axle 12 is controv steering mechanism 16, which may form desired. Connected with sai buffer 17, which swings with the wagon-bodies 18 are provided v' 19, connected byking-bolts 2O with swinging axles 21, carrying the supporting-wheels 22 of the wagons. Said swinging axles 21 also carry to swing therewith buffers 23. rlhe traction-engine is coupled to the adjacent wagon by a link 24, pivoted at one end to the king-bolt and at the other end to a pin 47, mounted on the buffer 23 adjacentto the tractioirengine. The adjacent faces of the buffers 17 and 23 are convex, and working between these convex faces are buffer members 25, which are supported from thelinks24. Each wagon is provided at each end with a handoperated steering mechanism, here shown as composed of drums 26, mounted on diagonal corners of the wagonbodies and connected by chains 27 with the corresponding axles. The drums 26 may be provided with 'any desired devices for facilitating their operationfor instance, with the movable hand-spikes 28,

' as shown at the frontend of the train in Fig.

' to any wagon when necessary.

J1, so that these hand-spikes may be applied are connected together by links 29, the ends of which are pivotally connected with the buffers 23 by pins 30. Attached both to the buffers 17 and 23 are springs 31, which are tw'o foreach buffer, and bear, respectively, on

- I the opposite sides of the adjacent links 24 and 29, tending yieldingly to hold the links in true longitudinal position. Theaxles of each vwagon have 'a peculiar connection with each other, this connection allowing the axles to swing toward each other at one end, so as to lie 4both vradial from a certain center or to swing out of parallelism with their bolsters, but re-v taining parallelism with eaeh other. rlhis connection allowing the above-described peculiar movement of the axles in its preferred form "com prises an intermediate part 32, the ends of which are conn'ected with branched end parts 33, the arms of the branches being attached to their respective axles at opposite sides of .the king-bolt thereof and said arms being drawn together by retractile springs 34, engaged with the arms, as shown.

The springs 34 tend to throw the axles and their connections into the position shown at the front end ofthe train in Fig. 1, and the peculiar connection enables the axles to swing into radial position, as shown, with respect to the rear ,wagon in Fig. 1 or to swing out of parallelism with the holsters, but retaining their parallelism, so that the axles turn in reversed arcs, the centers thereof being on opposite ,sides of the train.

The wagonsl versed to each other.

BEST AVAILABLE COF may place the necessary stress on the foi wardmost axle thereof. The steersman cants or cranks this forwardmost axle in one direction or another, according to the direction in which he desires to have the train move, and the front wagon will turn to one side or another, according to the strain placed on this front axle and the direction of said strain. The other wagons following the first will successively take the positions of the first wagon. Consequently the entire train will turn, following the direction of the front wagon. The turning movements of the following wagons and engine are due to the connections between the axles of each wagon, the peculiar connections between the wagons, and the peculiar connections between the engine and the adjacent wagon.

Referring to Fig. 1, it will be observed that the front wagon isrunning straight and that owing to the link 29 and buffers 23 the front wagon is exerting a strain upon the front axle of the second wagon, causing that axle to curve into the straight line being traveled by the first wagon. The flexible connections between the two axles of the second wagon will simultaneously tend to swing the rear axle of the second wagon, causing it to curve into the curve being taken by the front axle of the second wagon, the axles of the second wagon at the period indicated in the view turning, as before explained, in distinct curves re- Asthe rear axle of the second wagon changes its inclination to the bolster, as above explained, the front axle of the third wagon will by the action of th'e link 29 and buffers 23 be turned to follow the curves of the second wagon, and the rear axle of the third wagon will by the connection between the Vaxles ofthis wagon be turned also to follow the various curves executed by the preceding wagons, and, finally, the rear axle of the third wagon through the link 24 and buffers 23 and 17 will cause the swinging axle of the traction-engine to change its inclination and run into the iirst curve indicated on the diagram. These' various swinging movements of the axles are brought about bythe combined infiuence of the steersman on the front wagon and the pushing action of the engine-buffer 17, this buffer exerting on the convex face of the coacting buffer 23 a strain'in a direction corresponding to the inclination of the engineaxle at the time. In case the engine is drawing the train behind it the steering is done through the engine-axle 14, and the buffer 17 and link 24 then act to impart the various guiding movements to the following wagons, as well as to impart the power for moving the train. In that case the train may be made to take all of the curves as are indicated in Fig. 1, in which figure, however, the engineis supL posed to be pushing rather than pulling.

The various details of the construction and arrangement of the wagons and engine run- IOO ning-gears are not essential to my invention. A great latitude of variation may be resorted to without departing from the principle of operation above explained. In Figs. 2 to 5, however, l have shown the preferred arrangement of these details of construction, and they may be particularly described as follows:

As best shown in Figs. 2, 3, and 4, the boiler 10 of the traction-engine has a metallic bolster-block 35 fastened to the under side thereof at the front of the engine. The bolsterblock is formed with a vertical passage 35, crossed by a horizontal passage 35", in which fits the round -Lipper end 36a of the engine king-bolt Said king-bolt is held against vertical movement by a flange 36", bearing on the under side of the bolster-block 35, and a pin and collar 36, lying in the recess 35 and fastened to the king-bolt. The front axle 14 of the traction-engine is formed with a horizontal passage 14, passing longitudinally of the engine, and avertical passage 14", the latter passage flaring downward fromthe broken lines in Fig. 4. rlhe king-bolt has a square part 36d below the flange 36", lying in the upper part of the passage 14" of the axle 14.` Below the squared portion 36l the king-bolt is round, and the bolt is of suflicient length to project completely through the axle and downward ashort distance below the same. Fastened to the front corners of the lire-box 10" of the traction-engine are brackets 37, (best showninr Figs. 2 and 4,) to which brackets are joined the limbs of a V-shaped brace 38, 'this brace projecting forward -and having connection with the lower extremity of the king-bolt.

The said connection is made secure by a collar and pin 39, attached to the lower extremity of said bolt. It will therefore be seen that the axle 14 is mounted under the engine-boiler so as to allow the axle to swing freely, as before explained, and also to allow aslight vertical rocking of the axle with respect to the boiler and king-bolt, thus compensating for unevenness of the road over which the engine may be moving.

The arms of a quadrant 40 are keyed to the axle 14, and, as best shown in Fig. 2, this quadrant lies at the rear of the axle and is engaged with any suitable steering-gear 16 for imparting t-o the axle its characteristic swinging movement. The buffer 17 of the axle 14 is mounted loose thereon, but is held yieldingl y connected with the lquadrant 40 by means of springs and lugs 42. These devices for yieldingly connecting the buffer and quadrant, and consequently the buifer and axle, may be of any type desired, numerous variations therein being obvious to skilled mechanics. The before-mentioned coupling-link 24`is entered into the cavity 14aL in the axle 14 and is pivotallyjoined to the king-bolt. The buffer 17 has side iianges 17 or other equivalent stops to limit the swinging movement of the coupling-link, and springs 43 are arranged to aser AVAILABLE coe 3 bear between the link and the buffer on each side of the link, so as to yieldingly hold the link in true longitudinal position with respect to the engine. It will therefore be apparent that as the axle is swung under action of the gear 16 and quadrant 40` a corresponding movement will be imparted to the buiiier and to the link 24, first through the action of the springs 43 and, as the limit of independent movement of the link is reached, subsequently through the action of the stops 17. It also may be seen that the buffer, with itslink, will be held yieldingly in the plane of the quadrant 40 or. allowed upon the yielding of the springs 42 to move vertically through a limited arc independently of the quadrant.

The wagon-body 18 is in no manner affected by my invention, it being of any desired form and mounted on the bolsters 19 in the usual manner. Said bolsters carry the king-bolts 20 in essentially the same manner that the engine king-bolt is mounted. The axles 21 of the wagon are horizontally recessed to receive the king bolts and the ends of the wagon-reach 44, the reach being pivotally engaged with the king-bolts, as shown. The buffers 23,0f the wagon are mounted loosely on the axles, but are held yieldingly in horizontal position by. means of spring connections 45, with cross-arms 46 attached to the reach 44 near the ends thereof, as shown in Figs. 2and 3. The coupling-links 24 and 29 are connected to the buffers 23 by means of the pins`36'or 47, and said links are allowed a swinging movement in the buffers independent thereof and limited by side stops 23a. Springs 48 bear on opposite sides of the coupling-links, so as to yieldingly hold them in longitudinal position. The intermediate portions 32 of the iexible connection between the axles may be made up of a single 'link or of a number of links, as desired, and the forked end parts 33 of said connections may be made of uniform links or, as best shown in Fig. 2, they may be made up of turnbuckles 33, connected by rings 33, to which rings the springs 34 are also connected, and the Aturnbuckles being connected one to the intermediate part 32 of the connection through the medium of links 33c and the other to the axles 21 or other part connected to the axles through the medium of hooks and clips 33". Preferably the hooks and clips 33b are applied directly to the axles, as shown in Fig. 1, but they may with the same results be applied to the side portions of the buffers 23, as shown in Fig. 2, or in any other manner which will insure their action directly or indirectly on the axles, as explained.

rlhe buffers are provided with quadrants 49 to serve the double function of limiting the rocking movement of the body and bolsters on the axles and also of furnishing a connection for the steering-gear 26. The steeringgear may be lof any convenient sort, and, as

IIO

hereinbefore explained, two gears are preferably provided for each wagon, the drums being located on diagonally opposite corners on the wagon-bodies, as shown.

The bearing or buffer members 25 may be vof any desired form and act between the op-l posing surfaces of the buffers to transmit the -pushing strain from one to the other. Preferably these members 25 are formed of tough metal strips bent into the form essentially of a linch-pin or cotter, as shown in Fig. 5, this forni enabling the members 25 to be readily placed and held in position.

In heavy hauling the tracking of the wagonwheels is disadvantageous, inasmuch as ruts are formed in the roads and the road-beds seriously injured. It is an important feature of my invention that this tracking of the wheels may be prevented when desired without, however, interfering with the performance of the other functions of the tractiontrain. Fig. 6 illustrates this function, and it is attained simply by changing the relative length of the arms of each branched end portion 33 of the connections between the wagonaxles. This may be done either by lengthen ing one arm and shortening the other or by merely lengthening one arm. For this purpose the turnbuckles in the arms of the branches 33 are especially provided. In effecting this adjustment the lengthened arm of one branch 33 should be on the side opposite the lengthened arm of the other branch. (See Fig. 6, in which a indicates the lengthened arms.) It may be seen that with the adjustment an uneven strain will be placed on the axles, causing them to Swing into a slightly-cranked position, but in parallelism with each other, and then the wagon-body goes slightly diagonally on its course, while the wheels run true with the course of the train, but out of track with each other to a degree dependent upon the degree of the change in the relative length of the arms of the branches 33.

Various changes in the form, proportions, and minor details of my invention may be resorted to at will without departing from the spirit and scope thereof. Hence'I consider myself entitled to all such variations as may lie within the terms of my claims.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl.
