clear, and exactdescription thereof, which will enable others skilled inthe art to make and use the-same, reference. being had to the ac-' companying drawings, forming partof this specification.

. Figure 1 is a front view of my improved dumb-waiter. Fig. 2 is avertica'l section of the same, taken .through the line-9p 0'0, Fig. 1. of referenceindicate corre- Similar; letters My invention has for itsobje ctflto improve the construction of dumb-waiters, so that they may be easily and conveniently raised and lowered to or from any story of' the building and fastened and unfastened by any one upon any story, whetherabove orv below the waiter,

and which shall at the same time be simple in construction and easily operated; and it 0011-.

sists in the construction and'combination of j various parts of. the machine, as hereinafter morefully described.

Afrepresents the she1f,.shelves, or closet of the dumb-waiter, whichmov'es up and down upon ways B, attached tothe frame or casing O of the well, in which the waiter is. placed.

and. its other endfis attached to the weight F,

that balancesthe-shelf or shelves A, and which moves up and down in a well chamber or space I at theback or side of the well or chamber in which the said shelf or shelves move.

To the lower end of the weight F is attached one end of the rope G, which passes around a pulley, H, in the lower part of the well, and

its other end isattached to the bottom of the shelf or; shelves A, as shown in Fig. 1. By

this construction 'a person in the upper part.

of the building may raise and lower the waiter by operating the upper rope, and a person in the lower part of the building may raise and lower it by operatingthe lower rope.

I are right-angled levers, which are pivotedand drop into a notch or catch, L, formedin said edge, so as to stop and hold the said closet until-released by again operating the rod J'.

The levers I K are held imposition to catch upon the notch or catch L by the weight of the rod I, assisted,when necessary, by one, or more.

springs, M, connected with the rod I or levers J, as shown in Fig. 2.

Having thus described my invention, I claim as new and desire to secure by Letters Patent ,11. The combination of the rope G and pulley H. with the shelf, shelves, or closet A, rope D, pulley E, and weight F, substantially in the manner herein shown and described, andfor the purpose set forth.
