SPECIFICATION forming part of Letters Patent No. 583,843, dated June 1, 1897. Application iiled September 19, 1896. Serial No. 606,402. (Nomodel.)

To @ZZ whom it Worry concern:

Be it known that I, JUDSON P. CASSELMAN, a citizen of the United States, residing at Nebraska City, in the county of Otoe and State of Nebraska, have invented certain new and useful Improvements in Turn-Tables; and I do hereby 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.

My present invention relates to improvements in turn-tables for use in conjunction with railroad-roundhouses or points in railway systems where the construction is such as to necessitate the use of a turntable; and the primary object of the invention is to dispense with all manual labor possible and render the turning of the same automatic.

By means of this invention the engine may be quickly-and automatically placed in alinement with any tracks of a radiating` series or may be entirely reversed in position for travel upon the same track.

Vith these and other objects and advantages in view my invention consists in certain new and novel features of construction and combination of parts hereinafter described and claimed, and fully illustrated in the accompanying drawings, in which- Figure 1 is a plan View of the turn-table. Fig. 2 is a plan view of the crown-gear and connected parts. Fig. 3 is a transverse sectional view of Fig. 1. Fig. -t is a side elevation. Fig. 5 is a plan view of a modified form of turn-table. Fig. o is a sectional view of the saine on the line G 6. Fig. 7 is aV further modification in plan View. Fig. 8 is a sectional view of t-he same on the line 8 8. Fig. 9 is a sectional view taken on the line 9`9 of Fig. G. Fig. 10 is a detail sectional View taken on the line 10 10 of Fig. 1. Fig. 11 is a detail sectional viewr on the line 11 11 of Fig. 3, and Fig. 12 is a detail view of a modication.

Like numerals of reference designate like parts throughout all theligures of the drawings.

1 represents the pivoted track-section of the turn-table, the ties of which are connected by the side bars 2, having located thereon at a central point the vertical upright posts 3,

' situated in pairs and carrying the connecting These opposite pairs of npcross-beams 4..

rights and theircross-beams are firmly braced by the brace-rods 5, secured to the ends of each side bar 2 and running over the tops of' the cross-beams 4, and by the transverse brace G, connecting the cross-beams. Mounted on each of the cross-beams, centrally of the uprights 3, is a pulley 7, over which passes acable or chain 8, carrying at its outer end a' ed concentrically upon a bed-plate 12, pro-l vided with an ann ular toothed flan ge forming a crown-gear exterior to the annular 'flange of the circular table 11.

Interposed between the bed-plate 12 and the circular table 11 and supporting the latter are the friction-rollers 13. The rollers may be journaled all to the table 11 or all to the bed-plate 12, this being immaterial. The bedplate and the table are provided with central registering perforations or openings 14 and 15, leading down into the weight-cavity.

Mounted in diametrically opposite bearings on the table 11 is a tubular driving-shaft 16, carrying on each end a drum 17, upon which is wound the inner end of the cable or chain 8. Loosely mounted on this tubular shaft 16 is a clutch member 18, the companion of which, 19, is keyed upon said shaft. It is, however, allowed sufficient longitudinal movement to be readily thrown out of engagement with the clutch member 18 in a manner to be hereinafter fully described. Integral with the loosely-mounted member 18 is a drum 20, around which a cable 21, carrying at its lower extremity a weight 22, is given several turns and then passed upward between two pulleys journaled in an intermediate rail 23. The cable passes through a division in the rail and is secured to a sliding sleeve 24, mounted on the said rail and adapted to travel in both directions from said division in the intermediate rail. Attached to this sleeve is a link carrying areversible dog or catch 25. This dog or catchis adapted to be set-for an engine traveling in either direction on the track-section and to be lifted IOC into engagement with some suitable part of said engine, preferably a low transverse bar, by means of pins 2G, working in perforations in said intermediate rail and resting on leverbars 27, Afulcrumed at 2S and actuated by pins 29, resting on the opposite end of the weighted lever-bar 27. These pins 29 are set in the rail of the track proper and project slightly above the su rface thereof,su fiieien tly, however, to actuate the lever-bars 27 when pressed down by the tread of the enginewheels. It will be understood that this mechanism is duplicated on the other side of the intermediate rail division in order that the forward traction-wheels of the engine may lift the jaws of the catch 25 into positive engagement with the low transverse bar which follows.

As above stated, while the clutch member 19 is keyed upon the said tubular shaft 1G it is designed to have sufficient longitudinal movement to be thrown into and out of engagement with the loosely-mounted companion member 1S by the bell-crank lever 30, pivoted at 31 and having the short arm of the said bell-crank lever bifurcated and in engagement with an annular groove 32 in the clutch member 1S. This member is normally pressed into engagement with the companion member 1S by a spring Then the catch 25 is in engagement with the engine, the parts 1S and 20, when engaged with the part 19, act upon the tubular driving-shaft 16 as a break mechanism to stop its revolution and that ofthe driven shaft, to be described later. T he bell-crank lever 30 is operated by the hand-lever 34, pivoted at the point on the inner side of the bar 2 indicated and limited in movement by a stop-pin 35, also by the lever 45, pivoted upon the outside of the bar 2 and connected to the sliding weight by the cable 4G, through which medium said weight, when it reaches its uppermost point, draws said lever and moves the bellcrank lever 30, thus throwing the clutch members out of engagement. Connected to the hand-lever 34, at a point between its contactwith the bell-crank lever. and its pivot, is a locking bolt or rod 36, adapted to lock the track-section into engagement with any of the tracks radiating from said turn-table and to which this track section may be turned. The spring-arm 37, by pressure upon the long arm of the bell-crank lever 30, indirectly secures the bolt 3o' in its locked position and also assists the clutch member 19 into engagement with the member 18.

Mounted in the tubular shaft 1G for rotation and carrying at each extremity a pinion 39 is a shaft 3S, somewhat longer than the diameter of the crown-gear 40. The length of the shaft 38 is such that one or the other of these pinions may be thrown into engagement with the crown-gear by the U-shaped lever 4l at will, and thus reverse the direction of travel or revolutions of the track-section. Secured to the shaft 3S and housed by the hollow sectional casing 43, attached to the tubular shaft 1G, is a ratchet 42, and pivoted at diametrically opposite points in the housing 43 and engaging with the said ratchet are the'spring-pressed pawls 44.

From the foregoing description of mechanism and arrangement of parts it will be seen that when an engine or locomotive enters upon the turn-table track-section and the dog or catch 25, engaged by the depending transverse bar thereof, raises the weight 22, which isV allowed vertical movement within a suitable central cavity beneath the bed-plate 12, and at the same time revolves the tubular shaft through the medium of the clutch members 1S and 19, the weights attached to the cay bles S will be raised to their greatest height.

This is due to the winding of the cables 8 upon the drums 17, which are integral with the tubular shaft- 1G. Then when the weights reach the uppermost point on the tracks 9 the lever 45, connected to one of the weights by the cable or chain 4G, is drawn, and acting upon the long arm of the bell-crank 30 moves the sliding' clutch member 19 upon its key and out of engagement with the loosely or revol ubl y mounted clutch member 18. Then the driving-shaft 1G is oppositely revolved within the clutch member 1b' and drum 2O by the unwinding of cables 8, caused by the descent of the thereto-attached weights. As the shaft 1G, provided with the housing 43, carrying the spring-pressed pawls, reverses its revolution the said pawls drop into engagement with the ratchet 42, keyed to interior shaft 3S and drives said shaft forward in the same direction as the shaft 1G. This driven shaft 38, it will be remembered, carries at its extremities the toothed pinions 39, either one or the other of which, according to the direction in which it is desired the turntable shall revolve, is in m csh with the crowngear 40. These pinions by traveling on said crown-gear give the desired movement to the turn-table. Accordingly as one or the other of the two pinions is in engagement with the crown-gear so is the table 1l and the tracksection 1 caused to revolve in one direction or the other and when in alinement with the desired track is locked by means of the locking bolt or rod 36. By allowing the tracksection so to turn the locomotive nray be turned end for end on the same track from which it came.

The disengagement of the clutch members, which can also be accomplished through the working of the hand-lever 34, renders the reverse revolution of the shaft 1G possible. This reversing of the revolution of shaft 16, it will be noticed, is dependent upon the disengagement of the clutch members, as it is not desirable nor convenient to remove the catch 25 from its connection with the locomotive at this moment, and without such removal or such mechanism as is above described it would be impossible to revolve the shaft 1G, as desired. Hence the clutch member 1S with its inte- IOO gral drum 20 is revol'ubly'mounted, and when the separation occurs the shaft 16 is free to revolve within said drum and said catch 25 to remain engaged with the -part of the loco'- motive designed for the purpose. Then the turn-table is alined with the desired track, the catch may be dropped by simply backing the engine until the catch-holding rod passes the division in the intermediate rail.

Where it is desirable to stop the table at a point short of where the completed descent of the Weights would naturally stop it, the hand-lever 34 is employed to operate a brake mechanism or parts performing the functions of a brake mechanism. The parts which combine to form a brake mechanism, and which are fully set forth in the following description, act positively upon the driving-shaft 16 to stop its revolutions. By removing the pressure of lever 34 from the elbow-lever 30 the clutch member 19 is permitted to spring into engagement with its companion member 18 and thereby lock the shaft against revolution, as above stated. This is owing to the adverse force exerted on the said shaft by the tension of the cable or chain 21, which remains attached to the enginel by the reversible catch 25 until the bolt 36 has been shot by lever 34 and the table locked in alinement with the desired track and against rotation. The catch 25 may then be dropped by lthe engine and-service completed.

In Fig. 12 I have illustrated a slight change in the member having the drum by substituting for said drum a sprocket-wheel 46 and replacing the cable with a sprocket-chain 47, and to cause the chain to hug the sprocketwheel I employ and idler-pulley 48. By this construction I avoid the winding of the cable around the clutch member.

In Figs. 5 and 6 I have illustrated a modication of my weight-lifting mechanism, the

construction otherwise practically remaining the same as in the rst form. I provide a separate shaft for the clutching device, which said shaft 49 is provided with a fixed clutch member 50 and a loosely mounted clutch member 51, having gear-teeth formed integrally therewith, which are designed to mesh with a gear 52 of somewhat smaller diameter than the diameter of the gear of the clutch member. This clutch member 51 is formed with an annular depression,into which the bifurcation of the bell-crank lever 30 is adapted to take and throw said member into or out of contact with said fixed clutch member 50. This shaft 49 has its ends reduced, and on the same are loosely-mounted the segmental gears 53, carrying the pawls 54, engaging with the ratchets 55, keyed fast to the reduced ends of said shaft 49. Springs 56 bear upon the upper surfaces of the pawls and force them into close contact with said ratchets. These segment-al gears 53 are partially revolved byV rack-bars 57, secured to the extremities of a centrally-pivoted rock-bar 58,

which pivot is the end of a rock-shaft 59, ar-

ranged longitudinally of the track-section and beneath the ties thereof. This rock-shaft is provided with the oppositely-disposed rockarms 60, having projections extending upwardly therefrom and lying in the intervals between the rails. These rock arms are spaced some distance apart on the rock-shaft in order that they may be actuated at different periods of time and alternately oscillate the rock-bar 58 or cause first one rack-bar and then the other to move downwardly. It will thus be seen that when the clutch members are in engagement with each other the pressure of the treads of the locomotivewheels will rock the shaft 59, oscillate the bar 58, and by means of the rack-bars 57 partially revolve rst one and then the other segmental gear, cause the pawls attached thereto to actuate the ratchets, and so revolve the shaft 49, which, through the medium of the fixed clutch and the gearingbefore mentioned, will cause the tubular shaft 16 to revolve and then to raise the weights through the mechanism contained in the housing on said tubular shaft, consisting of the pawls engaging with the ratchet fixed on the shaft 38, to communicate motion to said shaft 38, when the bell-crank 30 is operated, and to the pinions 39, as in the first form before described. In this modification the tracks 9 are done away with and the cable 8 passes over the pulley 7 and is secured to the framework of the superstructure and a weight suspended from said cable by the pulley 7, as illustrated. The pulleys 7 will be changed from the position shown in Fig. 1 and will be journaled on the inside of each cross-beam 4.

In Fig. 7, a further modification, I have shown the mechanism of Fig. 5 placed longitudinally of the tracks and substituted for the mechanism for actuating the shaft 49, which in this form will be considerably lengthened. I provide a ratchet 61, actuated bya gravity-pawl 62, pivoted to one of a pair of crossed arms 63, pivoted at 64 and 64aL and provided with track projections 65, normally pressed above the tread ofthe rails by a spring 66. A series of these crossed armssor ratchet actuating devices may be placed along the length of the shaft 49, and thus rapidly raise the central weight 22, which in this form of mechanism directly influences the revolution of the shaft 38 through the pawl and ratchet mechanism before mentioned. The clutch member 19 is keyed upon the shaft 49, the same as in the first form, Fig. 1, to allow longitudinal play and is thrown into and out of engagement with the loose pinion-formed clutch member 18 by the lever-rod 67, actuated by the lever 34 in a manner similar to that in Fig. 1, and a like lever-rod 68, attached to lever 69, actuates shaft 38 longitudinally.

It'will be seen from the foregoing description of mechanism and arrangement cf parts that I have constructed an automatic turntable both simple and durable and suitable.
