LOCOMOTIVE REVOLVING CRAN E.

SPECIFICATIOIYT forming part of Letters Patent No. 682,703, dated September 1'7, 1901.

Application filed December 26, 1900. Elorial No. 41 107. (No model.)

To all "whom, it may concern;

Be it known that I, FRANK E. HULETT, a

. resident of Akron Summit county, Ohio, have A further object of my invention is to pro-' vide a crane of this character comprising improvements in the construction and arrangement of the hoisting'and motive machinery,

whereby the working of the crane is greatly facilitated and a considerable reduction is secured in the cost of operating-the same.

My invention therefore consists in providing means for steadying and retaining. the crane on the track of a trestle or similar structure by coupling the truck thereof to a movable ballast or counterweight.

' My invention also consists in constructing a crane of this character provided with a motive engine and a hoisting-engine, each capable ofv operating independently of the other, and meansfor supplying both of the engines from the same boiler or steam-s11 pply.

My invention further consists in the fea tures of construction and combination of parts hereinafter fully described in the specification, pointed out in the claims, and illustrated in the drawings.

The locomotive-cranes to which my invention particularly relates are designed to travel on standard-gage tracks, and are used for excavating coal, ore, or other material and loading it into cars. This employment generally necessitates that the tracks upon which the crane travelsbe elevated upon a trestle or similar structure. Heretofore great difficulty has been experienced when operating a crane upon a trestle in preventing the crane from being overturned by the weight of {the load in the grapple-bucket or through the reaction caused by the sudden releasing of the load from the grapple-bucket. As it is impossible to block up or prop the crane on a trestle in the same manner as can be done on the level ground, this difficulty has been overcome to some extent by clamping the truck of the crane to the rails; but this method has been found cumbersome and ineXpedient.

By my invention I provide means located at each of the four corners of the framework of the truck of the crane adapted to engage the adjacent corners of cars coupled at either end of the said crane. By these means the weight of the cars used for hauling the material excavated may be utilized as a ballast or counterweight to prevent theoverturning of the crane. A great advantage of thus steadying the crane by the weight of an adjacent'tender or car coupled thereto results from the fact that the stability of the crane will be the same whether the crane is moving or stationary upon the tracks. The crane can'therefore be used for excavating atone place and filling in at an adjacent place without loading the material into cars, which would be impractical in case the truck of the crane had to be clamped to the rails each time the grapple-bucket was swung.

Referring to the drawings, Figure I represents a side elevation of my crane. Fig. II shows afsection on lines II II, Fig. I. Fig. III is a section on lines III III, Fig. I. Fig. IV is an enlarged view of the sheaves. Fig. V is a sectional view on lines V V, Fig. IV. Fig. VI is an enlarged view showing the swivel-joint in the steam-pipe connecting the boiler and motive engine. Fig. VII is an enlarged view of a portion of the rod for operating the reversing mechanism of the motive engine.

Again referring to the drawings, a represents the truck of the crane, which is mounted.

in the usual way upon suitable sets of wheels a. At each of the four corners of the truck are secured the arms I), b,-b and 6 These arms project beyond the respective ends of the truck a sufficient distance to pass under boiler e, an engine f, and the standards g and g, which support a shaft 9 On the shaft g are loosely mounted the sheaves h, t', and

j. The sheaves h and j are provided with clutch members it and j for securing them so as to revolve with the shaft g The shaft g is operatively connected with the engine fby means of a gear-wheel g which is rigidly mounted on the shaft g and a gear Z, which is connected in the usual way with the 10 piston-rod of the enginef. A steam-pipe f connects the boiler c with the hoisting-enginef. Between the sheaves h and z a bar m is mounted so as to revolve freely on the shaft 9?. The sheaves h and z are provided with lugs 7L2 and t respectively. When the sheave h is revolved, it will make about one turn and will then pick up the bar m and will carry it around another revolution until the bar engages the lug t on the sheave t and the two sheaves will revolve together. Likewise, when the sheave h is reversed it will revolve once, then pick up the bar on, and then turn once more before engaging the sheave 2'.

To the floor of the truck a is secured a double-cylinder engine 19, which is connected in the usual way with the driving-wheels of the truck. A reversing-valvet is secured to the floor of the truck and is connected with the cyl- 0 inder of the engine by pipesp. A steam-pipe 6 leads from the boiler e to the upper part of a vertical pipe or cylinder 0, which passes through the center of the turn-table. The pipe 6 is secured to the cylinder 0 by means of a 3 5 swivel-joint 0, which allows the upper portion to turn while the lower portion remains stationary. A steampipe e connects the lower portion of the cylinder 0 with a reversingvalve t. A lever r is mounted on the platform 0, one end of which is connected to a rod 0", which passes down through the cylinder 0 and is connected at its lower end to a bellcrank lever s. The openings in the cylinder 0 are well packed to prevent the escape of 3 steam. The bell-crank lever is in turn connected to a rod 5, which is secured to the operating-arm of the reversing valve.- This allows the engine to be started or reversed from the platform 0.

As a means for reversing the driving-engine I have shown a reversing-valve located between the steam-supply and cylinders of the driving-engine; but I do not claim this as part of my invention, as my means for actuating the reversing mechanism can be adapted to operate any style of reversing mechanism, either reversing valves or links.

What I claim is- 1. The combination of a truck, a derrick mounted upon said truck, and means formed integral with and arranged at the respective corners of the said truck adapted to engage the adjacent corners of a car coupled to the said truck.
