. .lo all 'whom 'it may concern.'

Be it knownthat I, IVALTER FERRIS, a citizen of the United States, and resident of South Milwaukee, 'county f Milwaukee, and invented certain new and useful Improvements in Turn-Table Mechanism for Railway Pile-Drivers and the Like; and I do hereby declare the following to be a full, clear, and exact descrlption of the invention, such as will 'enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to .railway pile drivers, steam shovels, snow plows, or other machines which may need to be reversed to enable them to get at their work.

It has special reference to apparatus of this kind in which the carbody .on which the machine is mounted carries atits under portion a turn table which may be supported on the railway track and on which the car and machine as a whole maybe turned end for end, in order to reverse its direction.

-The object of the invention is to provide an improved form of turn table, an improved arrangement of the turn table with respect vto the car body, and improved mechanism forraising and lowering the turn table as a whole4 with respect4 to the car, so that the latter may .be elevated and swung around through 180, after which. the turn table is ,moved upward from its operative position, wherein 1t supports the car, to a position directly beneath the bottom or1 deckof the latter, in which position it will not interfere with the track when the machine'is being transported from place to place.

I also aim to provide improved mechanism, operating in'con'necti0n with the turn 40 table, .by means of which the car body may be swung end for end by hand power after as just.

it has been lifted from the track, indicated.

. In carrying out the invention, the turn i' table is constructed of upper and lower frames that are mounted beneath the bottom of the c'ar and held together against relative vertical and turning movements when the turn table 1s not in' use, each frame being provided with al'ball race'between which vand the ball race of the other framev anti-friction balls are interposed, so" that the swinging about of thelcar may be effected with a--minimum of friction. Extending structed in accordance down from the side beams of the car at the corners of the turn table are suitable pedestals on which are pivoted bell crank levers, said levers being also pivoted to the upper member of the turn table. These levers are preferably arranged in sets at opposite sides of the car and they are operated by means of hydraulic cylinders which, when A'the lower member of the turn table is supported from the track by means of suitable jacks, effect uniform pivotal movements of said bell crank levers about the pivots carried by the upper turn table member,.whereby the car body as a whole is raised by upward pressure applied to the aforesaid pedestals. Ihe lower member or frame of the turn table is provided with an internal gear and when the car body has been raised as indicated, the swinging about of the same is produced by a manually operated geared connection vwith said interna-l gear. When the car body is raised, the two members of the turn table must be freed from each other in Patented Jan. 24, 1911.

order to allow the turning of the upper member on the lower one, as will be understood, lbut when the swinging around of the car body is completed, and after it has been lowered again onto the rails, the two turn" table members are again locked together, the

raised into shipping position by a movement of the bell cranks in that first indicated.

I n\ the accompanying drawing z-Figure 1 is a side elevation of a railway pile driver provi-ded with turn table mechanism c0n with the invention,- Fig. 2 is an enlarged side elevation of the turn table mechanism, with certain .parts 'removed and other parts shown in section,

means of pipes 44 and 45 to afour-way valve 46, which in turn is 47 illustrated diagrammatically in Figs. 2 and 3. Said pump, in practice, is placed at any suitable 'point` on the car body and it is preferably drlven by means of steam -froln the boiler of the pile driver.` The pipe 44 communicates with the interior of the cylinder through an opening in the cylinder head 48, while ythe pipe 45 is connected with the cylindrical Wall of the cylinder near the opposite end, so that water introduced through the pipe 45 acts on the rear surface ofthe piston head 32a while water introduced through the pipe 45 enters-the annular space between the cylinder wall and the annular shell 32b of the trunk piston. The four-way valve 46 may'be operated in any convenient way, as by the crank 49, and the'valvev is so constructed and arranged as to permit the exhaust water passing out of the- pipe 45 or 44, as the case may be, to escape through an 'exhaust pipe 50 connected -withv the valve casing, it being evidentl that when the pipe 44 is exhausting, water will be supplied from the pumpthr'ough the pipe 45, and vice Versa. It is to be understood, however', that this particular I nanner of controlling theoperation of: the cylinder and piston does not yail'ect. the gist of the invention.

raise the car body when it is supported on the chairs of the lower turn table frame,l and I will now proceed to describe the devices by. which the 'car body may be swung end for erid by hand powerafter itlias been I raised up from the rails. This mechanism comprlses an internal gear 5 1 sultably se-- cured to the upper part of the lower ball race 23, and meshing .with Asaid gear is a pinion 52 carried by right stud shaft 53 journaled in fixed brackets or bearings 54 that are applied to transverse bars 55 carried by the upper ball race casting 14h.' At the intermediate portion of the stud shaft 53, the same carries a worm wheel 56 that engages a worm 57 carried by:

y latter is rigidly held in its' proper relation with the worm wheel 56. Applied 'to the opposite ends ofI the operating shaft 59 are It is to be uu'- dei-stood that although the internal gear is carriedl by the lower ball race, the rest of the swinging mechanism comprising the pinion, Worm gear, and worm" shaft, is-all carried by the frame of the upper 'ba-ll'race,

connected -to a pump The mechanism just described serves to the lower end'of an upsothat when the cranks 61 are rotated the p1n1on 52 Awill be rotated and moved along' .the inner circumference of the internal gear, which, of course, is fixed the result beingthatthe upper turn table, frame and the car body will be swung around until the pile for end.

.The operation-of the apparatus may be A briefly described as follows:.-When it is de# sired to swing the pile driver end for end, the chair frames 16, 41

or` bars 42 of the lower. turn table frame and placed on the rails beneath the jacks 42 at the .corners -of saidframe, being 'so' adjusted that their n ear the tops of the chairs 16.

lower ends are At this time,

the turntable will be in its uppermost position, each trunk piston '32 being' located adjacent the cylinder head 4'8 and the levers 17-18 having the position indicated in Fig. 2. Pressurel water lwill then be pumped from the Vpump 47 through the cylinder heads 48 by Way of the pipes 4 4, the fouragainst. rotation,.

driver is placed' end will -be removed v from their `shipping position on the brackets Y.'

80 the jack screwsway valve 46 being-suitably manipulated to produce this result, and it is `obvious that the'pressure'of the water. in each cylinder 19 will cause the piston rod 31to be thrust outward, as indicated in Fig. 3. This movement of the piston rod will cause the upp end of the correspondingbell crank 17 Vto move a short distance about, the correspond- 1 inw pin 28 as a pivot,'until the'pin 27 carries L'J l v the turn table down onto the. chairs wlth. the jacks resting on the latter, whereupon; the lever is moved about the pin' 27 as a pivot because said pin is maintained againstv further depression by reason ofthe fact that' the turn table is held up by the chairs'and jacks. Accordingly, the lpin 28,' that is carf ried by the pedestal 29, will be forced upward, as shown in Fig; 3, carrying with-it thev pedestal and the entire car' body, to which latter the pedestal is'bolted.. The car.

body will therefore be raised to such an ex-` -tenlt that itswwheels will clear the rails, the' center bearings of the car trucks being suit` ably constructed to effect this' result.; The movement of eachlever 17 is transmitted to the corresponding'lever 18- by means-of the connecting rod 33; as before explained, 'and' all four of the leversi'vill therefore operate" inthe same way. If the center of gravity' is at one side of the car center line, the cross shaft 38 connecting the two levers17, willv transmit from the lifting cylinder on-xfth light side to the pair of levers on 4the h" s1 e sufiicient. lifting force to bring then- '1:95

gravity whereby the same raising effect will beproduced at all four corners of the turn` ter of lifting eiiort under the-center ot`1A table.

lVhen the parts have reached the positiorr'shown in Fig. 3, the c'ar body can .be

swung,r end for end bymeans of the man ually operated worm shaft 58, as before indicated, the upper ball race rolling freely on the balls ,A; lVhen the car has been swung through 180, it can be lowered again, and this can be eii'ected by so manipulating the four-way valve 4G that the pressure water acting on the piston head will be exhausted, whereby the car is permitted Ato settle down onto the rails., the levers being moved back toward theirpnitial position. This'manipulation of the tour-.way valve also causes pressure water to be admitted to the cylinder through the pipel 45, which Vater Willtill the space between the shell ot' the piston and the cylinder Wall and act against the front face of the piston over a relatively narrow annular surface, whereby'the levers 17 andv 18 will be brought all the way back to their initial position in o 1der to restore the effectively prevented. lt will be noted that.`

the flower vvLt'rame'or member l5 of the turn table is' substantially below the side beams oit the car infall ofits positions, and accorde ingly itl does not interfere with the car body or any parts carried thereliy'unhen the pile driver is swung around.
