GEORGE W. PENDLETON, OF MINEOLA, TEXAS.

STEAM-CONDENSER.

Specification of Letters Patent.

Patented Nov. 5, 1907.

Application filed March 26. 1907. Serial No. 364.695-

To all whom it may concern:

Be it known that I GEORGE W, PENDLETON, a citizen of the United States, residing at Mineola, in the county of Wood and State of Texas have invented new and useful Improvements in SteamCondensers, .of which the following is a specification. v

This invention relates to a steam condenser of the surface type and relates more particularly to a combined condenser and re-boiler by which the noxious gases that are suspended in the water of condensation are effectually liberated before leaving the condenser, thus eliminating a re-boiling device from the live steam system as is generally employed in ice manufacturing.

The invention has for one of itsobjects to improve and simplify the construction and operation of devices of this character so as to be comparatively easy and inexpensive to manufacture, highly eflicient and reliable in service and adapted to operate'with a minimum of back pressure.

A further object of the invention is the provision of a sheet metal condenser over the exterior of which the cooling water is adapted to flow and provided with means that serves as a re-boiler for operating on the water of condensation so as to liberate any noxious gases therefrom.

With these objects in view and others as will appear as the description proceeds, the invention comprises the various novel features of construction and arrangement of parts which will be more fully described hereinafter and set forth with particularity in the claims appended hereto.

In the accompanying drawing, which illustrates one of the embodiments of the invention, Figure 1 is a central vertical section taken longitudinally of the con denser and re-boiler. Fig. 2 is a vertical transverse section on line 22, Fig. 1.

Similar reference characters are employed to designate similar parts throughout the several views.

Referring to the drawing, 1 designates the sheet metal body of the condenser which may be of any desired shape and size. In. the bottom of the body is a horizontal partition 2 suitably spaced from the bottom plate 3 so as to divide the interior of the condenser into a re-boiler compartment 4 and a condensing compartment 5, the compartments communicating through an opening 6 adjacent one end of the partition and having a deflector 7 for directing thepassage of the steam from the lower to the upper compartment. The compartment 4 has an inlet 8 that is adapted to be'connected with the engine 01' other apparatus exhausting steam to be condensed, said inlet being located at a point remote from the opening 6, so that the steam will traverse-the full length of the compartment 4. In the bottom 3 is a drain opening 9 that may be connected with a suitable valved pipe for leading off the water of condensation that might accumulate in the compartment 4.

In the condensing compartment 5 are a plurality of oppositely inclined plates 10 and 11 that are arranged with their upper ends in contact with the side walls of the body 1 while their lower ends are spaced apart from the adjacent side walls and bent downwardly at 12 to form chutes whereby each inclined plate discharges the water of condensation upon the one next below. The plates 10 and 11 divide the condensing compartment into a tortuous passage through which the steam is conducted. Each plate is provided adjacent its upper end with an opening 13 each having a deflector 14 that serves to direct the steam in the proper direction. At the bottom of the compartment 5 and arranged on the level with the partition 2 is an outlet 15 for the water of condensation that in practice is connected with a pipe leading the water through the usual course to the ice cans, as desired. At the top, of the casing is an outlet 16 through which the non-vaporizable and noxious gases mixed with the steam passes off from the condenser.

Extending along the top of the machine and secured to the front and back walls thereof are gutters or troughs 17 into which the cooling water is supplied and from which the water is evenly distributed so as to rundown the front and'back surfaces of the condenser and thus effectually condense the steam passing through the latter. On the front and rear sides of the condenser are longitudinally extending deflector plates 18 that shed the water from the sides of the compartment 4 so as to I prevent the cooling of the steam while passing through the same.

In practice, the steam passes into the compartment 4 and heats the partition 2 to a high temperature while moving first under and then over the latter in transit from the inlet 8 through the opening 6 to the opening 13 of the first inclined plate 10. The deflector 7 directs the steam longitudinally through the space directly over the partition 2 and toward the opening 13 and the upper stratum .of the steam is acted upon by the cold or water cooled front and rear sides of the condenser, while the lower stratum of steam assists in keeping the partition 2 hot. The steam passing through the opening 13 of the lower plate 10 is directed by thedeflector 14 toward the opening of the upper inclined plate 11 and after passing through the latter opening, the steam is directed toward the outlet 16, but is practically completely condensed before reaching the said opening. While passing through this course, the steam is condensed and the water of condensation flows down the inclined plates and through the chutes formed by the bent portions 12 until it finally reaches the partition 2. While passing over the partition, the water of condensation is re-boiled so that any suspended noxious gases are effectively liberated from the distilled Water and these gases finally discharge through the outlet 16.

Having thus described the invention, what I claim 1, In a device of the class described, the combination of a casing having a steam inlet and water and gas outlets, a partition dividing the casing into a re-boiler compartment and a condensing compartment, and means in the condensing compartment for directing the water of condensation along the partition for boiling the Water to liberate the suspended gases therein.

2. In a device of the class described, of a casing. a par tition dividing the same into compartments, means for admitting steam to the bottom compartment, means for sepa rating the gases from the steam in the upper compartment, means for supplying cooling water to condense the steam while passing through the upper compartment, and deflector plates on the casing for shedding the cooling water from the sides of the bottom compartment.

3. In a device of the class described, the combination of a casing, a horizontal partition therein dividing the easing into separate compartments, oppositely inclined plates in one 01 the compartments, chutes at the bottom ends of the plates, and means for conveying the steam successively over the plates.

4. In a device of the class described, the combination of a casing, a partition having an opening adjacent one end, an inlet for the compartment below the partition, oppositely inclined spaced plates in the compartment above the partition and having their lower ends bent to form chutes, and means for directing the steam successively over the plates and for preventing the steam from passing through the chutes.

5. In a device of the class described, the combination of a casing, a horizontal partition adjacent the bottom thereof dividing the casing into separate compartments, an inlet for the lower compartment for discharging'steam into the same, means arranged at the outside of the lower compartment for preventing; the condensation of steam therein, a plurality of oppositely inclined plates in the upper compartment on which the water-of condensation flows to the partition, an outlet for the water-of condensation, an outlet for the gases liberated from the steam, and gutters or troughs on the casing for discharging water over the exterior of the casing for condensing the steam in the upper compartment.

In testimony whereof, I aflix my signature in presence of two witnesses.

GEORGE W. PENDLETON.
