Specification of Letters Patent.

Patented J une 23, 1914.

Application filed June 16, 1913. Serial No. 773,948.

To all whom it may concern Be it known that I, MATHEW S. SoHwIN- NEN, a citizen of, the United States, residing at South Bend, in the county of St. Joseph and State of Indiana, have invented certain new and useful Improvements in Windlasses, of which the following is a specification.

The invention relates to an improved Windlass, designed particularly for use in connection with electric street lamps, and serving in such connection for raising and lowering or otherwise adjusting the lamp with respect to the pole.

One of the objects of the invention is the provision of a Windlass including a separable operating member designed for detachable cooperation with the Windlass when desired, whereby the lamp tender may actuate any number of windlasses through the use of a single operating member.

Another object of the invention is the provision of means whereby the Windlass is au-. tomatically locked against operation except succeeding the introduction of the proper operating member therein.

Another object of the invention is the provision of a Windlass, including an operating member, with the cooperating parts so constructed and arranged that the operating member may be adjusted to impart diifer-' ent speeds to the drum at will.

The invention in its preferred form of details will be described in the following specification, reference being had particularly to the accompanying drawings, in which Figure l is a view in section partly in e'levation of the improved Windlass, the operating member being shown therein. Fig. 2 is a section on line 22 of Fig. 1. Fig. 3 is a section on line 3-3 of Fig. 1. Fig. 1 is a section on line H of Fig. 1. Fig. 5 is an elevation of the operating member.

Referring particularly to the acc0mpany-' ing drawings, the improved Windlass comprises end bearings 1 and2 designed, through the medium of ears 3, for fixed connection to the pole or other support. The bearing 1 is centrally formed with a laterally projecting spindlei, of reduced diameter at its inner end at 5 and a hollow construction throughout the length of such reduced portion' to form a socket '6. 'The head 2 is formed with a laterally projecting spindle 7, of less lengtlrjthanfthe sp'indle. and

opening 8 extending spindle 7 the drum, which is otherwise hollow, is formed with a transverse partition 11 having a central opening 12, the wall of the opening being extended inwardly beyond the partitionas at 13, to provide a comparatively elongated opening. The wall of the opening 12 is formed with diametrically opposed recesses 14, for a purpose which will later appear. That portion of the spindle 4: ad acent the end plate of the bearing 1 is formed with a dimetrically arranged recess 15 extending n'early through the spindle, and in the upper end of this recess is pivotally mounted at 16 what I term a locking lever 17. The lever is of greater length than the spindle and the wall of the portion 5 of the spindle is longitudinally slotted at 18 to receive the lever. That portion of the drum surrounding the enlarged portion of the spindle 4 is formed in the adjacent wall with a series of rearwardly arranged recesses 19 with any one of which the outer or free end of the lever is arranged to cooperate, a coil spring 20 mounted in the recess 15 bearing beneathsuch free end of the lever to normally maintain cooperation of the lever V with the immediately overlying recess 19 of the drum. The opposite end of the lever is formed with a depending triangular shaped projection 21 for cooperation with the'operating member, as will later appear. That portion of the drum overlying the spindle 7 is formed to present internal gear teeth 22, and a pinion 23 is pivotally mounted upon the head plate of the bearing 2 for,

cooperation with said internal gear, the pinion 23 operating in the opening of the spindle 7 previouslv described.

The operating member comprises a shaft 23 formed at one end for the reception of the handle 24 and at the opposite end with a series of spaced

locking collars

25, 26, and

27, the opposing side surfaces of these collars converging outwardly to provide for operating the locking lever, as will later 12 in the partition, and into the chamber 6,

appear. The shaft connection between the

end collars

25 and 26, and between the collar 27 and the shaft proper of the operating member, is of slightly less diameter than that of the shaft proper, as at 28, the ends of the shaft proper being inclined at 29 to oppose the inclination of the proximate surface of the adjacent collar; The shaft connection 30 between the

collars

26 and 27, however, is of materially less diameter than the shaft connection 28, for a purpose which will presently appear. Immediately adjacent that end of the shaft 23 remote from the locking collars, said shaft is'provided with a fixed annular series of ribs or teeth 81 formed for cooperation with the teeth of the pinion 23, said ribs or teeth 31 constituting what will be hereinafter termed the drive pinion. The shaft 23" is further provided with diametrically opposed fins 32 of a size to cooperate with the recesses 14 in the transverse partition of the drum, said fins however, being spaced a greater distance from the drive pinion 31 than are said recesses 14 from the intermediate pinion 23 in the drum.

In normal position, with the operating member removed, it will be understood that the spring 20 will force the operating end of the locking lever 17 into the particular overlying recess 19 of the drum, so that the drum is locked against rotation. Upon the introduction of the operating member, the same being passed longitudinally through the opening 8 in the bearing 2, the opening in the spindle 4, the respective locking collars will, through cooperation with the projection 21 on said locking member, lower the locking end of said lever, until when said member is in the position shown in Fig. 1,

the projection 21 will bear upon the shaft connection 28 and maintain the locking end of said lever free of connection with the re-. cesses 19 of the drum. In this position of;

the parts the drive pinion of the operating member is in cooperation with the interme-' diate pinion 23 of the drum, so that upon rotation of the operating member through the handle, the drum is rotated. If a reduced speed of the drum is desired, the operating member is moved longitudinally in the outward direction until the fins 32 cooperate with a diametrically opposed pair of the recesses 14 in the partition of the drum, whereupon the rotation of the operating member drives the drum at a reduced speed and in the opposite direction from that of the pin-1 ion drive.

The parts are so proportioned that in the movement of the operating member to uti-.

lize the fins as the driving means the locking collars will be moved past the locking lever projection until such projection rests upon the shaft connection 28 between the

collars

25 and 26. In this position the lever will be maintained in unlocked position, though it will be obvious that in moving from one position to the'other the projection 21 of the lever will cooperate with the reduced shaft connection 30, and in this co-' operation will permit such movement of the lever as will induce a locking cooperation of the operative end thereof with the particular recess 19 of the drum. Therefore, in the change of the operating member from one drive'to the other, the drumis temporarily locked against rotation. r

The improved Windlass provides a means whereby a single operating lever may be used for cooperation with a number of wind-' lass structures; in which the Windlass is automatically locked against rotation in the absence of the operating member; ,and in which the parts are constructed to permit adjustment of the operating member to actuate the windless in either direction.

That is claimed is Y 1. A Windlass including a rotatable drum,

means for normally locking the drum against rotation, a separable operating member arranged for detachable connection with the drum, and cooperating means carried by the drum and member for actuating the drum in either of two positions of the member therein.

2. A Windlass including a rotatable drum, means for normally locking the drum against rotation, a separable operatingmember arranged for detachable connection with the drum, and cooperating means carried by the drum and member for reversely actuating the drum in either of two positions of the member therein.

3. A Windlass including a rotatable drum formed with an internal gear, a lever for locking the drum against rotation, an operating member arranged for detachable connection with the drum, 2. drive pinion carried by said member, a pinion arranged intermediate said drive pinion and gear, and means carried by the member to actuate the lever to release position.

4. A Windlass including a rotatable drum, independent drive members carried by the drum, an actuating member adapted for removable connection with the drum, and spaced driving members carried by the member, said driving members being arranged to permit cooperation of but one thereof with one of the drive members of the drum in any one position of the actuating member.

5. A windless including a rotatable drum, independent driven elements carried thereby, an actuating member adapted for removable connection with thedrum, independent drive elements on the said member-for cooperation respectively with'the driven elements of the drum in different positions of said member within the drum, and actuating member controlled locking means for the drum.

6. A Windlass including a rotatable drum, independent driven elements carried thereby, an actuating member adapted for removable connection with the drum, independent drive elements on the said member for cooperation respectively with the driven elements of the drum in different positions of said member within the drum, a lever for normally locking the drum against rotation, and means carried by the actuating member for moving thelever to release position.

7 A Windlass including a rotatable drum, independent driven elements carried thereby, an actuating member adapted for removable connection with the drum, independent drive elements on the said member for cooperation respectively with the driven elements of the drum in diflerent positions of said member within the drum, a lever for normally locking the drum against rotation, and means carried by the actuating member for moving the lever to release position, said means permitting locking movement of the lever in the position of the actuating memher when both of the drive elements are out of cooperation with the driven elements.

8. A Windlass including bearings, a drum rotatably mounted therebetween, said drum being formed with an internal gear and with a series of locking notches, a locking lever pivotally mounted on one of the bearings and adapted to cooperate with the locking notches, a pinion carried by one of the bearings and cooperating with the internal gear, a drum partition, formed with an opening and with diametrically opposed notches in the wall of said opening, and an actuating member having a series of collars to cooperate with and move the lever to release position, a pinion formed on said member to cooperate with the pinion on the bearing, and diametrically opposed fins carried by the member to cooperate with the opposed notches in the drum partition.

In testimony whereof I afiix my signature in presence of two witnesses.
