THOMAS SPENCER MILLER, OF SOUTH ORANGE, AND JOSEPH II. DICKINSON, OF MONTGLAIR,

NEW JERSEY.

PORTABLE DERRICK.

Specification of Letters Patent.

Patented June 9, 1908.

Application filed. November 18, 1903. Serial No. 181,714,

T all whom it may concern:

Be it known that we, THOMAS SPENCER MILLER, a citizen of the United States, and a resident of South Orange, county of Essex, and State of New Jersey, and JOSEPH II. DICK- INSON, a citizen of the United States, and a resident of Montclair, county of Essex, and State of New Jersey, have invented a new and useful Improvement in Portable Derricks, of which the following is a specification.

In that class of derricks which straddle a railway track so as to permit cars to pass freely beneath the derrick platform, the transfer of the support of the derrick from its own supports to a carrying car has heretofore been accomplished by operative mechanism controlling the effective length of the derrick supports so that by shortening the same the derrick platform was lowered. until it rested upon the car.

The object of our present invention is to enable the derrick to be loaded upon the car in a more expeditious and simple manner and it consists in interposing between the derrick and the car, supports by the movement of which in contact with the car, the derrick may substantially lift itself until its supports are raised from the ground and it is loaded bodily upon the car.

In the accompanying drawings, Figure 1 is a side elevation of a derrick containing our invention carried by an ordinary logging car beneath it. Fig. 2 is a plan view of the derrick-platform and the apparatus carried thereon with the superstructure above the platform removed. Fig. 3 is an end view of the same corresponding with Fig. 1, partly in section. Fig. 4 is an end view of the same but showing the derrick standing upon its own supports with the car free to run beneath its platform. Figs. 5 and 6 are modifications. Fig. 7 shows propelling mechanism in the combination.

1 are the railway ties; 2, the tracks.

3 is an ordinary logging car carrying the log-bunkers 4.

5 is the derrick-platform from the opposite sides of which project downwardly the rigid supports 6, 7, so as to straddle the car and stand upon the ends of the ties.

8 is the boom.

9 is the hoisting-rope-drum.

10 is the hoisting-rope.

11 is the car spotting-rope and 12 the ropedrum for the same.

13 is the boiler and 14 the water-tank.

15 and .16 are members which are forced down from the derrick-platform against the bunkers of the car to load the derrick onto the car and lift the derrick- supports 6 and 7 clear of the ties. As exemplified in the drawings, these members consist of two longitudinal. sills adapted to extend from bunker to bunker of the car and movable up and down in slots through the derrick-platform.

The mechanism for o crating the mem bers 15 and 16 is exemp lied by two forms in the accompanying drawings. In Figs. 1, 2, 3, and 4 it consists of the two pairs of owns 17 each fixed to a shaft 18 to which are fixed the s )rocket-wheels 19 connected with the sleeve 20 on the shaft 21 of the drum 12 by the chains 22 and sprocket-wheels 23. 24 is a clutch splined to the shaft 21 and adapted to interlock with a clutch 25 on the end of sleeve 20. 26 are chains suspending the members 15 and 16 from the hubs of cams 17. 27 are stops fixed to the shafts 18 whereby the rotation of said shafts in a direction to unwind said chains is limited. When the derrick is in operation and standing upon its own supports, the clutch 24 will stand disengaged. When it is desired to load the derrick on the car, the clutch 24 will be moved longitudinally into engagement with the clutch 25 and the derrick-engine run in such direction as to rotate the cams 17 downwardly until the support of the derrick is transferred from the supports 6, 7 to the supports 15, 16, on the car. I/Vhen it is desired to unload the derrick from the car, the engine is run in the opposite direction with the clutches in engagement and the cams 17 are thus moved upwardly while the chains 26 ,compel the members 15 and 16 to follow the upward movement of the cams.

In the forms shown in Figs. 5 and 6, we substitute for the cams 17 above described, the levers 32 pivoted to the derrick structure at 28 and connected with the members 15 and 16 by hangers 29. Each pair of said levers 32 is coupled with the piston-rod 30 of a cylinder 31 that may be operated by steam from the derrickboiler, or other power, such as by hydraulic power taken from the pump of the derrick.

In Fig. 7, we have shown traction mechanism on the car and driving mechanism therefor on the derrick, so that after the car has coacted with the derrick to enable it to lift itself off of its supports it continues to coact to enable the derrick to act as its own locomotive. 41 is a spur-wheel on the derrick platform driven in any suitable way from the derrick engine. 33 is a spur-wheel on the car adapted to be engaged or disengaged therewith by therocking of the frame 34. 35 are sprocket-wheels fixed on the car axles and 36 are chains by which the same are driven from sprocket wheels ,37 fixed on the counter shaft 38 of spur-wheel 33. A form of this is also shown in our applications 181204 filed Nov. 14, 1903, and 169862 filed Aug. 18, 1903. In Fig. 7, we have also com bined with the mechanism above described log bunkers consisting of a central portion 39 adapted to support the lifting members 15, 16, and into which the bunker ends 40 telescope so as to be capable of an inboard movement to permit the car to ass between narrow derrick supports. A orm of this is also shown in our application 181205 filed Nov. 14., 1903.
