DERRICK-ISWINGING MECHANISM.

SPECIFICATION forming part of Letters Patent No. 749,352, dated January 12, 1904.

Application filed January 31, 1901. Serial No. 45,402. (No model.) V

To a. whom it may concern: 7

Be it known that I, CHARLES A. BAEoHroLi), a citizen of the United States, and a resident of Westfield, in the county of Union and State of New Jersey, have invented'a new and Improved Derrick Swinging Mechanism, of which the following is a full, clear, and exact description.

My invention relates to an improvement in devices particularly designed for use in swinging a derrick, and comprises certain novel mechanisms by which a drum may be made to reverse its direction while receiving its power from a shaft revolving in a constant direction.

My invention further comprises the combination of'the various parts of the engine and the derrick with said drum and its reversing mechanism.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan view of my device connected with an engine. Fig. 2 is an end ele vation of the same. Fig. 3 is a longitudinal taken upon the line 3 3 of Fig. i. Fig. 4 is a cross-section'taken upon the plane which includes the journals of the bevel-pinions, and Fig. 5 shows the combined winch-head and pinion. My device is primarily intended as an attachment to hoisting-engines and to be used for the reception of a rope or cable which leads to opposite sides of a bull-wheel placed upon the mast of a derrick, whereby the derrick may be swung into any desired position.

It is'ev'ident that the device may be used 1 for other purposes than swinging derricks and 40 also may be built as a component part of the engine, and I do not, therefore, wish to be understood as limiting myself to the use of the device for this particular purpose nor to thedevice when built as an attachment.

In the drawings, A represents a drum of any type of hoisting-engine. The shaft A of this drum, which is usually non*reversible,'is provided with an additional pinion a, which jacent end of the drum.

meshes with a gear B, mounted upon the shaft O of my device. A form of construction whichis much preferred by me is partially shown in Fig. 1 and a detail thereof shown in Fig. 5. The pinion or gear a; is therein made as a part of the winch-head a. he shaft C is supported in suitable bearings in the frame C and is rotated constantly in one direction by means of the connection through the gears a and B with the shaft A" of the hoisting-engine. I have shown this power connection as with one of the drum-shafts. Itwill, however, be understood that the connection may be made with any convenient portion of the hoistingengine.

Upon the shaft O is loosely mounted a drum D, upon one end of which is formed a bevel gear-wheel d. Mounted upon this shaft and facing said bevel-gear is a friction-disk E, which issplined to the shaft so that it will turn therewith, butmay slide lengthwise thereof. This disk is provided with friction-blocks e, which enter a groove f in a loosely-mounted friction member or disk F, which lies between the friction-disk E and the end of the drum. The outer surface of this friction-disk receives a brake-band G or is otherwise engaged by any suitable brake mechanism, so that the rotation of the disk F may be prevented when desired. The friction-disk has a flange F projecting toward the drum and preferably terminating closely adjacent to the radial flange d of g the drum, so as to close the space lying between the body of the friction-disk F and the ad- A cup-shaped member is thus formed.

A bevel-gear H, corresponding in size with the bevel-gear d'of the drum, is fixedly se- V cured to the shaft C next to the friction-disk F and between the same and the end of the drum. A spider or frameI is loosely mounted upon the shaft between the bevel-gear H andthe end of the drum and preferably snugly filling the space between the same. This spider or frame has its periphery secured to suitable bearing-surfaces upon the cup-shaped frictiondisk F by means of bolts 2' or other suitable means, so that when the two are secured together they form substantially one member. This spider has openings 1 opposite each other and adapted to receive the bevel-pinions J. Said pinions are mounted upon pins or journals K, which have their inner ends screwed or otherwise secured into the hub of the spider 1. Locking set-screws Z2 are also shown. The spider or frame I, together with the friction-disk F, thus constitute a pinion-carrier, which is provided with friction-surfaces 'engaging, respectively, with the friction member e and the brake G. These pinions mesh with both of the bevel-gears H and d. Oilchambers k are provided in these pins or journals, extending lengthwise the axis thereof and reaching to the shaft C. Radial oil-openings 7c are provided, reaching to the bearingsurface of the pinions J thereof. The axial hole extends to the outer end of the pin and is closed by means of a screw L, which is threaded in an opening in the flange E, which lies in line with the axis of said pin or journal. By removing one of these bolts the pinion-journal,as well as the bearing of the spider upon the shaft, may be oiled, and the oilingopening may then be closed by the insertion of the bolt. Any suitable means are provided by which the friction-disk E may be moved, so as to be engaged or disengaged from the friction-disk E. A spring M of customary form is provided for pushing said disks out of contact.

The reversal of the drum is secured by the means described in the following manner: If the brake G be loosened upon the disk F and the friction-disk E be forced into engagement with the disk F, then the disk F is forced to revolve with the disk E-that is, with the shaft C. This carries the spider I and the pinions J carried thereby around the shaft at the same speed. Consequently as they engage with the bevel-gear H, which is secured to and rotates with the shaft, there is no rotation of the pinions upon their journals and they simply have amotion of translation about the shaft A and serve merely as levers connecting the bevel gears H and d. Consequently the drum D is made to rotate with the shaft and at the same speed. If, however, it is desired to reverse the direction of the drum, this is done by freeing the friction-disks E and F and by applying the brake to the disk F, so as to prevent or check its rotation. When this occurs, the spider carrying the pinions is either held stationary or is permitted to rotate with the shaft at a less speed. Consequently there will be a rotation of the pinions J upon their shafts, and this motion will be communicated to the drum D, causing the same to rotate upon the shaft and in the opposite direction therefrom. The speed of rotation of the drum D may be-made to vary from nothing to the same speed as the shaft in either direction by either setting the friction devices up hard or by applying them lightly, so as to permit slipping of the parts.

The mechanism herein shown for operating the friction-disk E is of the old and well-known construction, which employs a pin N, movable within a slot extending lengthwise the shaft, and the pin-actuating rod N, which lies within an axial bore in the shaft and at its outer end passes through a yoke N with which it is threaded, so that by means of rotation of the rod N the friction-disk E may be pressed against the disk F. To the outer end of the rod N is secured the arm or lever O. This being an old and well-known construction which is most frequently employed for such purpose, fuller description and illustration are unnecessary. Any other friction-applying device may be substituted therefor.

Alongside of and parallel with the axis of the drum is placed a shaft P, to which an operating-lever P is connected. This shaft has two arms p and p, to the first one of which the friction-operating arm 0 is connected by means of a link 0 and to the other of which the brake-band G is connected. These parts are so arranged that the friction is applied by movement of the lever in one direction, while the brake is applied by the movement of the lever in the opposite direction, while in the central position of the lever neither brake nor friction are in use.

It will be seen that my device is very compact and simple in its construction and may be operated to swing the derrick or to reverse the action of whatever mechanism the cable leading from the drum is connected with by the simple operation of throwing a lever in one direction or the other from its central position.

The device when mounted upon an independent frame may be attached to any form of engine. Whether mounted in this manner or built into the engine-frame, it provides a reversible drum in connection with a non-reversing engine. The rope used with the drum D is placed thereon so as to wind upon one end and to wind off of the other. If desired, the drum may be shortened and made as a winch, so that only a few turns will be needed upon the drum at one time. I

The device is well adapted for all uses where a reversible drum is desired in connection with a non-reversing engine.
