OLIVER CROSBY, OF ST. PAUL, MINNESOTA.

LOCOMOTlVE-CRAN E.

SPECIFICATION forming part of Letters Patent No. 572,195, dated December 1, 1896.

Application filed April 6, 1896. Serial No- 586,419. (No model.)

To all whom, it may concern.-

Be it known that I, OLIVER CROSBY, of St. Paul, Ramsey count-y, Minnesota, have invented certain Improvements in Locomotive- Cranes, of which the following is a specification.

My invention relates to improvements in locomotive-cranes, its object being to provide an improved driving mechanism therefor so connected to traction-wheels on theopp'osite rails of the track whereby said wheels are positively operated so as to each do its proportionate work.

To this end my invention consists in mounting the platform of the crane upon four beams arranged one at each corner thereof, which beams in turn are supported each upon a pair of two-wheeled trucks, the connections between trucks and beam and beam and platform being pivotal to permit freedom of adjustment of the truck-wheels to the curvatures of the track. Intermediate of the front and rear trucks on each side .I arrange a driving or traction wheel, the two being connected by a cross-beam or truck and each being double-flanged to prevent derailment. It is apparent that in passing around curves there is of necessity relative lateral movement between the driver-truck and the platform. This is provided for by an intermediate traveling connection. This consists of a secondary platform upon each of said trucks, directly over its wheel, fitted with antifriction rollers,

weight of the platform and crane is carried, a suitable plane-surfaced plate resting upon the platform, and between this plate and platform are arranged heavy springs with adj usting-screws, by means of which any desired pressure of portion of the load is applied to the plate and its carrying-rolls. The driving-wheels are operated from a common source of power, so as to be driven at a uniform com bined speed by means of an interposed epicyclic train and connected gear. This train is mounted upon a counter-shaft having a sliding connection with the driving-gear which operatively engages the traction-wheels, so that the power is transmitted to these wheels no matter what their lateral position may be with relation to the platform, owing to the My invention further consists in the features of construction hereinafter particularly described and claimed. In the accompanying drawings, forming part of this specification, Figure 1 is a side elevation of my improved apparatus shown with the crane removed. Fig. 2 is a crosssection of the same, looking toward the carrying-wheels and showing the means for driving the same from a central vertical shaft. Fig. 3 is a similar enlarged detail of one of the carrying-wheels and its connected parts; and Fig. 4 is a detail side elevation of the'driving parts, looking toward the epicyclic train and driving-wheels beyond.

In the drawings, A represents the platform, each corner of which is mounted upon a beam 2, each beam in turn being mounted upon a pair of trucks 3 and 4:, each of the trucks havin g carrying-wheels 5. Thetrucks turn about vertical pivots 6, and the beam 2 also turns upon a vertical pivot 7, connecting it to the platform,whereby tl1e truck-wheels run freely upon the rail 8 without regard to its curvatures. trucks on each side of the platform is a driving. or traction wheel. 9. This is doubleflanged, as shown best in Fig. 3, so as to pre-' vent derailment or lateral slip in either direction upon the rail. These wheels carry and are rigidly connected together by the cross beam or truck-10. Upon the top and at each of the cross-beams is arranged a secondary platform 36, carrying series of antifriction- Arranged between the front and rear rolls 11, and upon these rests the plane-sun .of gears 10, one upon each end of the same,

by means of which it receives its driving power. These mesh with the pinions 17, carried by the shaft 18, turning in

bearings

10, 20, and 21. This shaft also carries the gear 22, which meshes with the pinion 23. This IOC pinion has an extended hub 24, which serves as a journal therefor, turning in the bearing and having an end flange 34, preventing longitudinal or sliding movement in the bearing. The connected member of the compound driving-shaft 26 slides freely through the hub of said pinion, but is held from turning by means of the spline of feather 27. The two members of the compound shaft are connected by the epicyclic train B, made up of the beveled gear 28, carrying the beveled pinions 29, which mesh with the pinions 30, keyed on the shaft 26. The gear 28 is driven by means of the gear 31 upon the vertical driving-shaft 32, which is connected to the source of power by any suitable means, such as the gear 35.

In operation the nuts 33 of the screws 15 are set to apply any desired and requisite load to the traction-wheels. Power then being applied to the driving mechanism the traction-wheels are both positively and uniformly driven, and on equal speeds on a straight track, but on meeting a curve in the track the epicyclic train distributes the power to the wheels, so as to drive them without slipping around curves, the traction-wheels and their cross-beam moving laterally with relation to the platform, the antifriction-rolls permitting of this movement and the pinions 23 sliding on the shaft 20.

I claim 1. In a locomotive-crane, the combination with the main platform and its groups of carr yin g-wheels arranged at each corner thereof, of the traction-wheel on each rail intermediate of the forward and rear carrying-wheels, their connecting beam or truck, the laterallyslidable connections between said cross-beam and platform, the driving-shaft, and the epicyclic train for transmitting power therefrom to both said traction-wheels.

2. In a locomotive-crane, the pair of con nected traction-wheels therefor arranged one on each rail, the antifriotion-rolls carried by I combination with the front and rear carryingwheels, of their intermediate traction-wheels, the rigid connection between said tractionwheels, means for driving said wheels, and the laterally-traveling connection between said wheels and said vehicle.

5. In a vehicle of the class described, the combination of the medially-arranged traction-wheels on both rails, their rigid connecting-bar, the common driving mechanism for said wheels, the interposed epicyclic train, and the laterally-traveling connection between said traction-wheels and vehicle.

6. In a vehicle of the class described, the combination with the front and rear carryin gwheels, of the intermediate traction-wheels, the bar connecting said wheels, the bearingplates and an-tifriction-rolls constituting a lat- .erally-traveling connection between said traction-wheels and the vehicle, means for applying any desired load to said traveling connections, the driving-shaft upon said vehicle, the pinions having hubjournals carried upon said shaft permitting relative sliding movement, and the operative driving connection between said pinions and traction-wheels.

7. In a vehicle of the class described, the combination of the flanged traction-wheels on opposite rails, their rigid connecting-bar, the laterally-traveling connection between said bar and vehicle, consisting of the series of antifriction-rolls, the plate bearing upon the same, and the springs and tension-screws interposed between said plate and the body of the vehicle, the common source of power, the epicyclic train connected therewith, the driving-gear for the opposite traction-wheels, and the interposed slidably-connected driving-shaft and pinion for operating said traction from said train.

8. In a vehicle of the class described, the combination with its main body or platform, the vertically-swiveled carrying-trucks at the corners thereof, the intermediate drivingwhcels, their rigid connection, the source of power carried by said vehicle, and the laterally-slidable driving connection between said source of power and said traction-wheels.

In testimony whereof I affix my signature in presence of two witnesses.
