JOHN F. METTEN, OF PHILADELPHIA, PENNSYLVANIA. ASSIGNOR TOYTHE WILLIAM CRAMP & SONS SHIP AND ENGINE BUILDING COMPANY, OF PHILADELPHIA, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA.

SPECIFICATION forming part of Letters Patent No. 780,368, dated .Tanuary 17, 1905. Application filed June 6, 1904. Serial No. 211,229.

T0 all 'wtmit it pta/y concern:

Be it known that I, JOHN F.'METTEN, a citizen of the United States,'residing in the city and county of Philadelphia, State of Pennsylvania, have invented a Novel Construction of Winches, of whichV the following is a specification.

My invention relates to Winches, and particularly to those provided with a connected motor.

It consists in providing an improved variable-speed gear between the motor and the winch-drums and in providing safety devices by which any interlocking of the gear that would endanger the motor or its connections is prevented.

It further consists of novel features of construction, all as will be hereinafter fully set forth.

Figure 1 represents in end elevation a winch embodying my invention, Figs. 2 and 3 are side elevations of the same, and Fig. 4 is a plan view, parts of these three views being removed for cle'arness of illustration. Fig. 5 represents, on an enlarged scale, a fragmentary section through line x, Fig. 4. Fig. 6 is a similar view through the line 1/ y of that figure. Figs. 7 and 8 are respectively left and right elevations of theshaft shown in Fig. 6.

Similar numerals of reference indicate corresponding' parts in the ligures.

Referring to the drawings, 1 designates the base or frame of a hoisting device or winch in the lower part of which may be provided a casing 2 for a resistance-box. Mounted on the frame 1 is a motor 3, having a projecting shaft 4, on one end of which is mounted a pulley 5, adapted to cooperate with a frictionband 6, connected. by means of suitable links 7 and 8, to'a foot-lever 9. At the other end of the shaft 4 is a pinion 10, which meshes with a gear-wheel 11, secured by a spline or otherwise to a collar 12, rotatable on the shaft 13, at each end of which shaft is mounted a winch-drum 14. Also secured on the collar 12, adjacent the gear-wheel 11, is the pinion 15, adjacent which is a gear-wheel 16, secured to rotate with the shaft 13.

Mounted to rotate in a bearing 17 in the frame 1 is a shaft 18, shown as having an eccentrically-extending portion 19, on which freely rotate the gear-wheel 2O and the pinion 21, which may be integral with or secured to each other. It will be understood that the construction of gearing operable in place of or with the clutch constitutes a system of back gearing and direct gearing, respectively providing for a change of speed.v

At the outer end of the shaft 18 is a lever 22, by which the shaft may be rocked. As shown in Fig. 2, it is provided with the usual locking device 23, engaging in notches 24 25 in an arc-shaped rack 26. From the inner end of the shaft 18 projects a pin 27, engaging' in a notch 28 of a lever 29, pivoted at 30 in the frame 1. The free end of the lever 29 is preferably curved upward, as shown at 31, and is adapted to be moved toward and from the shaft 13 for a purpose which will hereinafter appear. Mounted on the shaft 13 is a collar V32, adapted to enter into and engage with the collar 12, the two forming when engaged a jawclutch by which the gear-wheel 11 and pinion 15 are operatively connected to the shaft 13. The collar 32 is moved longitudinally on the shaft 13 by means of a bell-crank lever 33, shaft 34, and rod 35, which lead to alever 36, pivoted in a bracket 37, secured on the frame 1. The lever 36 may have a locking device 33, engaging in notches 39 and 40 in the seg'- mental rack 41, which forms part of the bracket 37. An ordinary controller 42, operated by a lever 43, is shown as mounted on the frame 1. It is of course unnecessary to show the connections of the controller and of the resistance-coils 44 with the motor 3, as these may be of any desired relation and form no part of the present invention.

The free end 31 of the lever 29 when inserted between the clutch members, as seen in Fig. 2, prevents movement of the clutch members. When the lever 29 is not thrown and the cluch members are brought into engagement, the space occupied by the free end 31 in Fig'. 2 is occupied by the clutch members, and movement of lever 29 is checked at that when the current is turned on the motor 3, the pinion 1() on the motor-shaft, as-well as the gear-wheel 11 and pinion 15 on the collar 12, will be continuously rotated. Then the parts are in the position shown in Figs. 2 and L of the drawings, the rotation of the motor will be communicated through the pinion 10, gear-wheel 11, pinion 15, gear-wheel 20, and pinion 21 to the gear-wheel 16, which is keyed to the drum-shaft 13. In this case the drums 141: will be moved at a relatively low speed, due to the three reductions caused by the difference in number of teeth betwcen'the gearwheels and the relatively small pinions. 1V hen the load on the winch is light or when for any reason it is desirable to rotate it ata higher speed, the lever 36 is thrown to the right of Fig. 2 of the drawings until the lock 38 engages in notch 40 on the rack 41. The effect of this is to cause jaws of the collar 32 to enter and engage the jaws in the collar 12, to which the gear-wheel 11 and pinion 15 are secured. It is obvious that to do this it is necessary to first remove the bar 29 from its proximity to the shaft 13, as in the position shown in Fig. 2 of the drawings. lt prevents the entrance of the collar 32 into the collar 12. 1t is therefore necessary for the operator to first throw the lever 22 to the position shown in Fig. 3, so that itsloek 23 engages with the notch 25 in the rack 26. The effect of this is to turn out the bar 29 as well as to rock the shaft 18, thereby releasing the gear-wheel 20 and the pinion 21 from their engagement with the pinion 15 and gear-wheel16, respectively. The levers 23 and 36 having been thrown, as thus described, the rotation of the motor 3 is communicated to the shaft 13 by means of the pinion 10 and gear-wheel 11. In this case the pinion 15 and gear-wheel 16 rotate idly, while the gear-wheel 2O and pinion 21 are at rest. It is evident that the operation of these trains of gears is independent of the direction of motion of the.motor, which may of course be provided with the usual reversing mechanism. I have shown the brakeband 6 as applied to a pulley 5, mounted on the motor-shaft4; but it is obvious that a similar band may be mounted on any other rotating portion or that any other form of brake desired may be employed.

It is evident that various changes may be made by those skilled in the art which may parting from the spirit of my invention or that a single lever may be substituted for the two'levers 22 and 36 shown.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
