Specification of Letters Patent.

Patented N 0V. 1917.

Application area september 13, 1917. serial No. 191,194.

To aZZ whom t may concern.'

Be it known that I, JOHN H. SNELLING, a citizen of the United States, residing at East Orange, in the county of Essex and State of New Jersey, have invented a certain new and useful Improvement in Vindlasses, of which the following is a specilication.

The invention relates more particularly to ship windlasses, and the object of the invention is to providel a windlass of this type having a wildcat and gipsy'head, and their operating and controlling means, in compact form, easily and quickly assembled, and adapted to be readily installed on the vessel in proper position without requiring the service of skilled engineers.

The invention consits in certain novel features of constructionV and arrangement by which the above objects are attained, to be hereinafter described and claimed.

The accompanying drawings form a part of this specification and show the invention as it has been carried out in practice.

Figure l is a front elevation of the improved windlass.

Fig. 2 is a plan view thereof.

Fig. 3 is an end elevation.

Fig. 4e is a plan view of the base and bit head, showing the shaft in place, and corresponding to Fig. 3.

Fig. 5 is a vertical section, partly in elevation, on a larger scale, showing the wildcat and locking head and the means for connecting it to the latter.

Similar letters of reference indicate the same parts in all the figures.

A is the base-plate adapted to be bolted to the deck or other support, and A1 is a standard or bit head cast integral therewith, bored to receive a shaft B set longitudinally of the base with its ends projecting in each direction from the bit head which serves as its bearing.

On the front and rear faces of the standard are the bits A2 and on the upper face are the lugs or guides A3 adapted to serve as usual.

Each end of the shaft B is provided with a key-way, b and b1, and on one end is mounted the gipsy head C having a toothed wheel or ratchet C1 cast in one therewith, and secured by a key C2 in the key-way b to revolve with the shaft. On the opposite end of the shaft immediately adjacent to the bit head is a ratchet wheel D joined to the on one side and the ratchet wheel D on the j other, with freedom to rotate therein.

Next to the wheel D and loosely mounted on the shaft is the wildcat E of the usual form having a peripheral groove e on its outer rim in which is received the brakeband F, and adjacent the outer face of the Wildcat is a locking head or disk G secured to the shaft by a key G2 in the key-way 1.

The upper face of the base A is finished at AL and A5, the former to receive a yoke H carrying the brake opera-ting means, and the latter a bracket J carrying the clearing guard finger J1 for the wildcat, and A6 is the chain-pipe cast integral with the base in proper relation to the wildcat to receive the chain therefrom. i

K K1 are heavers mounted on bushings on the shaft B and equipped as usual to cooperate with the ratchets C1 and D to turn the shaft, and L L are pawls pivotally mounted on bosses vA7 formed on the bit head A1, adapted to engage and hold the ratchets.

lOn the outer face of the Wildcat is a series of radial lugs E1 El having spaces between them in which is received the inner end of a block-key G1 mounted to slide in ways g in the locking head G and its boss G3, and thus engage the Wildcat and compel it to rotate with the shaft. The block-key has a lip G4 arranged to strike a corresponding offset g1 in the ways g and limit its outward movement, and has a transverse hole in which is received a pin G5 thrust through corresponding holes in the boss G3 to insure maintenance of engagement. When disengaged by an outward movement of the blockkey the hole is exposed beyond the boss G3 and by reinserting the pin G5 the block-key is held reliably in the disengaged condition.

The brake-band F is attached at one end to the yoke H, and at its free end to a bolt F2 pivotally mounted in an eccentric or cam Fs having a socket F4 for the reception of a bar, not shown, by which the brakeband may be tightened or relaxed.

The functions performed by the several members are as usual and need not be described.

It will be noted that the arrangement permits the highest degree of compactness, and that the ratchets and heavers are located on opposite sides of the bit head and immediately adjacent thereto so that the shaft is Well supported against the strains at those points.

By locating the locking head G outside the Wildcat, the latter is confined on the shaft and the clutch or block-key conveniently presented and easily operated.

By removing the keys C2 and G2, the gipsy head, locking head, heavers, and Wildcat maybe removed and the shaft With the ratchet Wheel D thereon WithdraWn from its bearing in the bit head for storage or transportation; and by reason of the self-contained arrangement the Windlass may be easily and quickly assembled and readily installed by the ship carpenter or other mechanic in the desired location.

I claim:-

l. In a Windlass, a base-plate, a bit head thereon, a shaft rotatably mounted in said bit head With its ends overhung, a gipsy head secured on one end of said shaft and having a ratchet on its inner end adjacent said bit head, a ratchet Wheel on the other end of said shaft adjacent said bit head, heavers centered on said shaft, a locking head secured on said other end of said shaft, a Wildcat loosely mounted on said shaft betWeen said ratchet Wheel and locking head, and means for separably engaging said locking head to said Wildcat.

2. In a Windlass, a base-plate, a bit head thereon, a shaft rotatably mounted in said bit head With its ends overhung, a gipsy head secured on one end of said shaft and having a ratchet on its inner end adjacent Copies of this patent may be obtained for ve cents each, by addressing the said bit head, a ratchet Wheel on the other end of said shaft adjacent said bit head, heavers centered on said shaft, a locking head secured on said other end of said shaft, a Wildcat loosely mounted on said shaft betWeen said ratchet Wheel and locking head and having a series of radial lugs, and a block key slidably mounted in said locking head and adapted to engage said lugs.

3. In a Windlass, a base-plate having a bit head cast integrally thereWith, a shaft mounted to rotate in said bit head With its ends overhung, a gipsy head secured on one end of said shaft and having a ratchet on its inner end adjacent said bit head, a ratchet Wheel secured on the other end of said shaft adjacent said bit head, a locking head secured on said other end of said shaft, a Wildcat loosely mounted cn said shaft betWeen said ratchet Wheel and locking head, and having a brake drum, means for separably engaging said locking head to said Wildcat, a clearing guard finger for the latter, and a brake-band for said drum, said base-plate having a chain pipe cast integrally therewith in proper relation to said Wildcat, and finished surfaces for the reception of the brake-band operating mechanism and for the bracket of said finger, and said bit head having bosses formed thereon to receive paWls for said ratchets.

In testimony that I claim the invention above set forth I affix my signature, in presence of tWo Witnesses.
