WlNDLASS-BEAM.

SPECIFICATION forming part of Letters Patent No. 348,370, dated August 31, 1886.

Application filed May 27, 1886. Serial No. 203,383.

To all whom it may concern..-

Be it known that I, EDWIN I-I. WHITNEY, of Providence, in the county of Providence and State of Rhode Island, have invented a.

certain new and useful Improvement in the manner of Securing the Loops of the Rods which Connect the Clamps to the Beam of a Ship-lVindlass, of which the following is a specification.

My invention relates to the construction of the wiudlassbeam; and it consists, particularly, in making it of such form that when the brake-levers areinserted into their sockets they will rest upon the upper side of the beam along portions which project beyond the entrance to the socket-openings.

Heretofore the sockets for the brake-levers have been made in either end of the beam, and the loops of the rods which connect the beam with the clamp arms or levers have hung over the top of the beam with the brakelevers inserted therein. Notches in the upper side of the beam have been used to keep the loops in the desired position on the beam; but Very frequently when the Windlass was in rapid operation the loop upon one side or the other would be thrown out of the notch where it had been placed and thus cause very disadvantageous operation.

My improvements effectually obviate the difficulties mentioned, for by forming the sockets for the brake-levers in a central portion of the beam which projects above the ends of the beam, and then making the notches or depressions for the loops of the beam-connections with the clamps along the lower or end portions of the beam, when the brake-levers are inserted in proper position in their sockets they will rest upon or over the loops and hold them securely in the notches where they have been placed.

In the drawings accompanying this specification, Figure 1 is a front elevation of my improved windlass-beam with the loop of a connecting-rodhungina notch upon either end of the beam and the end of one of the brake-levers inserted in its socket. Fig. 2 is an end View of the beam with a loop hung upon it. Fig. 3 is an end View of the beam with the end 50 portion in section cut through the lowest part (No model.)

of the notch nearest the socket for the brakelever. Fig. 4 is the loop. Fig. 5 shows a modification of the manner of making the notches for the loops by cutting them in the brake-leverinstead of thebeam. Fig. 6shows a still further modification by forming a depression in the end of the beam and holding the loop in the desired position by means of pins inserted in holes in the beam. Fig. 7 is a front elevation of a Windlass having myimproved beam attached thereto, and Fig. Sis an end View of the same.

Corresponding parts are indicated by the same letters in the several figures.

A is my improved Windlass-beam.

B are the brake-levers.

C are the loops of the rods which connect the beam with the clamp-levers.

o is the clamp-lever.

D is the frame of the Windlass.

a is the pivot on which the beam tilts.

b are cars on the ends of the beam to assist in holding the brake-levers.

e are the sockets for the ends of the brakelevers B.

9 are the notches or depressions for the loops 0.

Fig. 5, are the notches made in the brakelevers.

g'', Fig. 6, are the pins to be inserted in holes in the side of the beam on either side of the loops to hold them in the desired position.

1) are the pins to hold the brake-levers in their sockets.

p are the pins to hold the brake-levers in their sockets when constructed as shown in Fig. 5.

w is the loose drum or wild-cat.

It will be readily understood that when the loops 0 are hung over the beam A in the 0 notches therein and the brake-levers are inserted into their sockets and secured there by a pin, 1), that it will be impossible to throw the loops out of place as long as the brake levers remain.

As it would be a matter of some more expense and labor to make the notches in the brake-lever, as shown at Fig. 5, I ordinarily prefer to make them in the top of the beam, as shown in Figs. 1 and 7, where they can be formed when thebeam is cast. This form also 1 clamp-connections, whereby the loops are se- 10 seems preferable to the use of pins, as shown curelyuheld in the position desired by fixing in Fig. 6. the brake-levers in their respective sockets,

I claim substantially as described. A Windlass-beam havim the brake-1ever T sockets in a portion thereo? above the plane EDWIL WVHITNEY' of the upper surface of the ends of the beam Witnesses: and notches or depressions across such end HENRY B. RosE,
