WINDLASS.

Specification of Letters Patent.

Application filed April 7, 1908.

Patented April 20, 1909.

Serial No. 425,602.

To all whom it may concern.'

Be it known that I, 'WALTER J. VAIL, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Vindlasses g and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in windlasses and has relation more particularly to that class acting in conjunction with a chain and it is the primary object of a device of this character to be employed as a wire stretcher.

It is also an object of the invention to provide a novel device of this character, including aworm gear forthe operation of the same.

It is also an object of the invention to provide a novel device of this character which will be simple in construction, efficient and advantageous in practice and comparatively inexpensive to manufacture.

Vit-h the above and other objects in view, the invention consists in the details of construction and in the novel arrangement and combination of parts to be hereinafter more particularly referred to.

In describing the invention in detail, reference will be had to the accompanying drawings forming part of this specification, wherein like characters of reference denote corresponding parts in the several views, and in which,

Figure 1 is a view in elevation of the invention, and Fig. 2 is a view taken on line 2-2, Fig. 1.

In the drawings, 1 denotes the body portion of the invention, which is cup-like and has formed in the upper edges of the sides thereof, the alining recesses 2 which form bearings for the shaft 4. One end of the shaft extends beyond the body and is squared for the reception of an operating handle 5 or other operating means.

To the shaft 4 within the body 1, is fixed a worm 6, which meshes with a worm wheel 7 fixed on a shaft 8 mounted in the ears 9 projecting from the ends of the body 1.

Formed with one face of the wheel 7, is a drum 10 having side flanges 11. The inner face of each of these flanges has formed therewith a star wheel 12, a portion 13 be'- tween the succeeding points 14 being straight. The ortions 14 form a pocket in which rests a 15 of a suitable chain, while the connecting link at right angles thereto will extend between the star wheels. The points of the wheel hold the link 15 againstundue displacement until the drum 10 has revolved suiiiciently as to bring a second link in a position similar to the link 15 hereinbefore referred to.

The base of the body 1 is provided with a projection or lug 16 having a perforation 17 through which passes a bolt 18 for pivoting to the lug 16 a clevis 19 or other attaching means. This clevis 19 is engaged by any suitable anchor, after which the handle 5 is rotated and the chain 2O will move any article to which it may be xed.

When the device is employed as a Wire stretcher, it is only necessary that the end of the wire to be stretched, is secured to the end of the chain, as is believed to be obvious. Attention is also directed to the fact that the shaft 8 is removable and that in order to assemble the device, it is only necessary to place the shaft 4 in the recesses 2 and to move the Wheel 7 on the shaft 8 and said shaft 4 will be effectually held against displacement. In other words, it will be seen that the shaft 8 holds the various parts of the device in assembled position.

I claim:

A windlass comprising a body having an open recess, a shaft, said open recess permitting lateral insertion of the shaft therein, a worm on the shaft, ears carried by the body, a shaft mounted in the ears, a wormwheel fixed to the shaft between the ears meshing with the worm on the first named shaft, said wormwheel holding the first named shaft against displacement, a drum formed'with one face of the wheel and means for rotating the first named shaft.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

WALTER J. VAIL.
