The Schedule referred to in these Letters Patent and making part of the some To all whom it may concern:

I Be itknown that I, Jonzs'EConv, of the city al county of New York, and State of New York, have invented certain new and useful Improvements in Noiseless Bell-Pulls; and I do hereby declare that the fol! lowing is a full and exact description thereof.

By noiseless bell-pulls, I mean those in which a cushion of rubber or other soft material is employed to soften the concussion produced, when the handle of the bell-pull is suddenly liberated. v

My invention is intended more particularly for use in the pilot-houses of steamers, but it may be employed with advantage in manyother situations.

A good example of the old arrangement of the cushion is found on the ferry-boat Pavonia, at New York city, finished, andprovided with the bell-pulls, in or about 1863. p A box is provided in the stationary work, which contains a piece of rubber, through which the slide of the bell-pull operates. The slide, after being drawn up, to cause the bell to strike, may be liberated as suddenly, and allowed to drop as rapidly as we please,

without noise or concussion, because, on descending, an enlargement of the slide is received on the rubber, and the blow is noiseless.

But an objection to this arrangement is foundin the fact that any lubricating-material applied to the slide is liable to get upon the rubber and dissolve it, fatty matter being peculiarly destructive to rubber. My inventionconsists in reversing the arrangement, and carrying the rubber on the slide. It obyiates the abovenamed objection, and, in a great measure, protects the rubber from the oil or other material, which might be vspilled. upon the bell-pull. It also conceals the rubber,

so that the device can be made more tasty in appear-- ance. V

. I will proceed to describe what I consider the best means of carryingout my invention.

Figure-1 is a side elevation of the entire apparatus.- 4

Figure 2 is alongitudinalvertical section. Figure 3 is a front view; Figure 4 is a horizontal section, on the line S S, in 3. 4 Similar letters of reference indicate like parts in all the figures. y v 3 A a is the fixed part, which is screwed or otherwise secured firmly. The portion A is a flat plate. The portion a is a casing, cast on A, and enclosing the slide.

The slide-rod B is attached byits lower end to the I wire, 0,, which operates the bell. It is provided with a stop, I), which prevents it being drawn up too far with the handle B, which receives the grasp of the hand,

and with a box, B open on the lower and back side, which contains rubber, as indicated by D.

The box B is of such size as to enclose the casing a loosely, Without contact therewith.

Some pilots habitually lower the bell-pull gently, by

- lowering the hand with it, after drawing it up to strike the bell. For the use of such, my invention, or, any othernoiseless bell-pull, ,is of little importance; but when, as is the case with many pilots, the hand is allowed to slide off the handle, and release itat the top of its motion, the slide drops at a high velocity, and

i would, except for the rubber, strike a severe blo'w upon the casinga, or some other metalliopart. My bellpull receives the blow entirely on the rubber D, and

.eflects this by the aid of my invention, with the rubber D, and its enclosing-box B in the reverse position, car:

ried on the slide, and striking against the fixed part a, instead of, as heretofore, being held on the fixed part,

"and struck by the slide or any attachment thereto. 3

I have tested the invention in the form above described, and consider it the preferable form, though many successful modifications may be made by any good mechanic, closed at the back,instead of open, and in such case, should correspondinglycut down the recess or upper part of the casing a, at the rear, .so'as to' receive the back of the box without striking, except on the rubber.. I can, if preferred in any case, provide another pieceof rubber, properly fastened, which shall stand in a fixed position below, to receive the force of the blow," insteadof the upper edge of the casing a. In case this arrangement is adopted, the rubber carried on the slide, according to my invention, will strike rubber on its descent, andthus two surfaces of rubber anda double elasticity willbe availed of. I do not'considerit of much importance thus to duplicate the provisions for cushioning the blow in ordinary cases, but there may be situations where it will be of use.

Having now fully described my invention,

What 1 consider new, and desire to secure by Letters Patent, is as follows: 7 1

I claim the carrying of the rubberJD'on the slide B,

attached to the wire, 0, leading to the bell, so that it I propose, if desired, to make the box B" Y
