FEEDING- APPARATUS FOR STEAM-BOILRS.
Specification of Letters Patent No. 29,444, dated July 31, 1860.
To all whom it may concern:
Be it known that I, THOMAS SHAW, of the city and county of Philadelphia and State of Pennsylvania, have invented a new and Improved Mode of Constructing Feeding Apparatus; and I hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawing and to the letters of reference marked thereon.
My invention consists of the construction of a simple feeding apparatus, which possesses the following requisites: ease and small cost of construction, certainty of action, and has no ground or packed joints, that communicate with the outside, to cause leaks, &c.
A part of the invention is the peculiar construction of the body or stationary part, through which the crank shaft passes as described hereafter. Also in the construction and balancing of a disk, arranged with chambers by means of a cap, secured firmly to the body, and in operating the said disk without the necessity of a packed joint as set forth hereafter. Also in employing an air ball or valve in connection with the air or water chamber, for the purpose of the escape of air or steam when feeding water to steam boilers as described hereafter. Also in employing an exhaust pipe as described hereafter.
In order to enable others to practice my invention I will now proceed to describe the manner in which I carry it into effect.
On reference to the accompanying drawing, which forms a part of the specification, Figure l is a side View of the feeding apparatus, Fig. 2 a vertical transverse section on the line 5 and 6, Fig. 3, Fig. 3 a vertical transverse section on the line l and 2, Fig. l, Fig. l a transverse view of Fig. l with cap removed, Fig. 5 a vertical transverse section on the line 3 and 4, Fig. l, Fig. 6 a cross section of the disk.
Similar letters refer to similar parts throughout the several views.
A is the body or stationary part, secured firmly to the base E, via, of pedestal I. B the air or water chamber. G a cap for inclosing the disk, steam or air tight. The body A has chambers f, and z, of the peculiar form described on the drawing, one of which communicates with the chamber B,
the other with the opening M, from whence it may be conducted to any steam boiler or vessel by means of a pipe. The disk has four chambers z' z' z' i equal distance apart, the face of which plays upon the face of the chamber or body, as shown in Figs. 2 and 3, which faces are caused to lit closely by the means of a pressure between the cap G and the disk K. Said pressure is produced by leakage, when the pressure in chamber L, overbalances that between the disk and cap. By this means it keeps a tight joint without the aid of screws or clamps, and gets rid of the necessary friction and wear attending them.
It will be evident that when in the rotation of the disk K, any of its chambers passes f (when said f is filled with water) that the said chambers will be filled with water, caused to run in by its own gravity, and when the said chambers t', reach the chamber it, they will empty for the reasons aforesaid, and will take in its stead chambers full of steam or air, which when under a pressure will be partially exhausted, when passing over the aperture a Fig. 4 which has communication with the chamber B by means of the pipe D. The object of the eX- hausting is to insure the successful filling of every chamber. The disk is caused to revolve by means of a crank, secured to the shaft L at H, said shaft has a feather at 7c, which fits into a corresponding slot in the disk K. The set screw Gr prevents the falling back of the disk K when there is no pressure.
The floating ball valve J is intended to be used when the Water` is fed from a higher elevation than the chamber B, intended to float on the water that it may close the aperture Z), when the chamber B is full of water and the reverse to permit the steam or airto escape, when the said air or steam has created suflicient pressure to force the water back into the supply pipe F. By this means it is perfectlyreliable and requires but little or no attention. It will be evident that the chamber z' in the disk K can be made of any capacity and of an eXact measure, that it may be used for either measuring liquid or dry measure.
I do not claim the alternately filling and emptying of chambers, for the purpose of feeding steam boilers with water, as that is scribed, and the employment of the exhaust plpe D for the purpose speced.
