To ctZZ whom it may concern.-

Be it known that we, HARRY N. CovnLL. of the city of New York, borough of Brooklyn, county of Kings, and State of New York, and CHARLES A. BAECHTOLD, of Westfield, Union county, and State of New Jersey, have invented a new and useful Improvement in Reversible Driving Devices, of which the following is a specification.

Our invention relates to an improvement in reversing driving mechanisms, and comprises novel features, which will be hereinafter particularly pointed out in the claims.

We have herein shown our device as applied to a winch-head in such manner that it may be reversed in direction of rotation, as desired. lit is, however, to be understood that our device may be used for connecting a shaft rotating constantly in one direction with any other device which it is desired to turn in both directions.

Figure 1 shows a longitudinal section of our device as applied to a winch-head. Fig. 2 is a section taken upon the line 2 2 of Fig. 1. Fig. 3 is a plan and partial section of a modification of our device.

The drawings accompanying herewith illustrate the form of construction now preferred by us, but not the only form of which we are aware in which our invention may be embodied. The construction of this form will now be described.

In the drawings, A represents the shaft, which is constantly rotated in one direction. In the case of a winch-head as applied to a hoisting-engine, for which use our device is particularly designed, this shaft would ordinarily be the shaft of one of the hoistingdrums. It will be so considered and described herein, although it is to be understood that our invention may be employed independently of ahoisting-drum. To this shaft is keyed or otherwise fixedly secured a sleeve B, which is provided near one end with aradially-extending flange B, one face of which is provided with teeth, forming a bevel-gear B Loosely mounted upon the end 6 of the sleeve B is a winch-head C, which is secured in place thereon by means of a washer'J and a bolt J, which screws into the shaft A. Loosely mounted upon the opposite end of the sleeve B or upon the section 6' thereof is a member which consists of a radial disk D, terminating at its outer edge in a circular ring D, thus forming a hood which incloses the operating mechanism and acts as a pinion-carrier. The inner face of the winch-head O is provided with teeth, forming a bevel-gear O, which corresponds in size and is located opposite the bevel'gear B Rad ially journaled upon shafts l, which are secured to the hood D, are beveled pinions I, which mesh with the two gears B and O. The outer periphery of the hood is provided with a friction-surface b adapted to be engaged by a frictionbrake of any character. The brake herein shown consists of a band E, which has its ends secured to pins in and carried by a lever K at unequal distances from a central shaft K. A disk F is secured to turn with the shaft A, but to slide longitudinally thereon, and carries one half of a friction-clutch, the other half being carried by the disk D. The friction-clutch may be of any desired construction, the construction herein shown consisting of annular disks or rings G and Gr, secured, respectively, to the disks D and F. Any other well-known form of friction device may, however, be substituted therefor, as the employment of the particular kind of friction device illustrated is not essential to the success of our invention. The disk D may he slid longitudinally of the shaft by any desired mechanism in order to apply the friction-clutch. If any other form of friction device is employed, a suitable applying mechanism therefor would be employed. The mechanism'herein shown consists of two cam-disks H and H, surrounding the shaft, the disk H being held against movement by engagement with the frame of the engine and the disk H being turnable upon the shaft. These two disks are f'zprovided with cam-surfaces it, so that whenjthe disk H- is turned the disk F will be moyed upon the shaft to engage or disengage the friction-clutch. The disk H is provided with an arm H which is connected, by means of a link L, with one end of the lever K upon the operating-shaft. The connections of the cams and the band-brake with the lever K are such that when one is applied the other is released. The shaft K may be mounted in any suitable manner and provided with an operating-handle at any convenient polnt.

From this description the operation of our improvement will be readily apparent. For instance, if it is desired to have the winchhead C turn in the same direction as the shaft the friction-clutch is thrown into operative position and the brake E is taken off the disk, so that the pinion carrying disk and the winch-head will be locked by the action of the friction device and will turn the shaft. If it is desired to reverse the direction of the Winch-head C, the friction-clutch is thrown out of operation and the band-brake E is brought into engagement with its brakingsurface, this holding the pinion-carrying disk stationary, so that as the sleeve member B turns with the shaft the radially-extending flange B will turn the pinions about their respective axes, and as such flange is fast with and turning in the same direction as the shaft the direction of rotation of the pinions intermeshing with the part C of the winch-head C will drive such winch-head in a direction opposite, or the reverse of the rotation of such shaft.

In the modification shown in Fig. 3 the winch-head C is not mounted upon the same shaft as that carrying the reversing mechanism. In this case the winch-head is mounted upon an auxiliary shaft A and is provided with a radial flange G which is provided with teeth forming a gear which is in mesh with a gear upon the shaft A, carrying the reversing mechanism. As herein illustrated, these gears are spur-gears. the gear C upon the winch-head being an internally-toothed gear. The reversing mechanism employed in this modification is similar in construction to that shown in Fig. l. The gear C corre- Sponds with the winch-head (l, as shown in Fig. 1.

It is evident that the reversing mechanism may be connected with a winch-head, which is separated from the main shaft A in any suitable or desired manner. The connections as herein shown are simply given as instances thereof. o do not, therefore, wish to be confined to the exact form of the device as herein shown, as the same is capable of many variations without departing from the spirit of the invention.

Among the characteristic features of our device is the use of two fixed and two loose members upon the revolving shaft and the use therewith of a single train of gears between the shaft and the winch-head or other object to be turned, the support for an intermediate gear of the train being engageable with friction devices, to be either held against rotation or to be turned about its axis.

One great advantage of our device is that the winch head or. drum being unobstructed at one end permits a rope being applied or removed without difliculty and enables the strain to be applied to pull upon either end of the rope without reversing the engine. It

is thus well adapted for use upon hoisting-em gines, and especially for the purpose of swinging a derrick.

We do not wish to be understood as limiting ourselves to the particular construction herein shown, butdesire to claim any constructions which are substantial equivalents or reversals of the construction herein illustrated.
