BOILER-COMPOUND HOLDER.

Specification of Letters Patent. Patented Apr. 15, 1919.

Application filed August 12, 1918. Serial No. 249,589.

The present invention relates to an im-- proved type of boiler compound holder, which is particularly applicable for use 1n steam boilers for dispensing the chemicals used to soften the water being used. The

primary object of the invention is to provide a simplified device which is easily manipulated and adapted for use in connection with boilers of various sizes or for softening diiferent quantities of water, which is durable, comparatively inexpensive in cost of production and maintenance, and efficient in furnishing to the water to be treated a uniform and regulated supply of material as required. i

With these ends in view the invention consists in certain novel combinations and arrangements of parts as will be hereinafter more fully pointed out and set forth in the claims.

In the accompanying drawings I have illustrated the construction of the invention according to the best modes I have so far devised for the practical application of the principles of my invention.

Figure 1 of the drawings is a central vertical longitudinal section of my invention.

Fig. 2 isan end view of Fig. 1 taken from the right of same.

Fig. 3 is a cross-sectional view taken on line 3-3 of Fig. 1.

Fig. 4 is a detail view of a portion of the outer casing taken on line 4.-4 of Fig. 2.

Fig. 5 is a side elevational view partly in section of a modified form of the device, showing an inner rack or crate designed to hold a number of receptacles containing chemicals. Fig. 6 is a cross-sectional view of Fig. 5

' taken on line 66 of Fig. 5. v

Fig. 7 is an end view of Fig. 5taken from the right of same. I 1

Figs. 1 to 4 inclusive of the drawings show more particularly the preferred form of the device, and Figs. 5 to 7 inclusive a modified form of the same;

.The numeral indicates a preferably cylindrical metallic tubular open-ended barrel designed to receive a number of inner receptacles 2 of similar cross-sectional form and adapted to contain a suitable boiler compound (not shown). The ends of the barrel 1 are closed by plugs or heads 3, which are provided with an annular inwardly turned flange 4 of proper size to fit neatly the inner peripheral face ofthe said barrel 1. Securing means for the heads is provided by means of thin metal strips 5 which are riveted to the inner wall of the barrel 1 at 6, and after the heads 3 are in place in the ends of the barrel, the strips 5 are bent over the, said heads at 7 thus securely fastening them in position. It will be seen that the rivetsv 6 are placed in the barrel 1 at the proper points longitudinally so that the edges 8 of the flanges 4 just bear against the inner heads of the rivets 6, so that the latter form convenient stops for the heads 3. As shown in Fig. '3 the flanges 4 of the heads 3 have to be slightly flattened at 9 to pass over the strips 5, but as the latter are made of tin their thickness is negligible. Attention is called to the fact that the barrel 1 is made preferably of heavier metal such as steel or wrought pipe, while the heads 3, and metal strips 5, and the inner cylinders 2, are made of thin metal such as tin. In connection with the cheapness of production of the device it may be stated that the inner cylinders or receptacles 2 can be made of the ordinary tin cans, or even second-hand or usedtin cans can be used, and the heads which have been opened in use can be resoldered shut after having been loaded with the chemicals used for softening the water, thus making the cost for inner receptacles very small. After the chemicals contained in the receptacles 2 have been dissolved and dissipated in a manner to be explained below, the outer barrel 1 can be reused by merely renewing the metallic strips 5, in case the latter have been injured at the point 7gby the bending which is necessary at this place.

Owing to certain ebullition movements of the water in the boiler (not shown), it

ment with the bottom of the boiler. 4 A bolt 7 12 clamps the band tightly around the barrel 1. If desired two such bands 10 can be used when it is necessary for the holder to be in a horizontal position, one "such being placed near each end. Each of the plugs or heads 3 is provided with perforations 13, one or more, at the right or elevated end of the barrel 1, and another (usually a single) perforation l-l at the oppositeor less elevated end'of the barrel. The purpose of these perforations is to admit the Water being softened by the chemical to enter the tube 1 at 14c and escape therefrom at 13, carrying with it the dissolved chemicals. Similarly each inner chemical containingreceptacle 2 is provided with perforations 15, and 16 (see Fig. 3), corresponding to

perforations

13 and 11 of the barrel 1, and for a similar purpose. It will thus be seen that the water enters the barrel 1 at 14, thence entering each of the inner receptacles 2 at 16, loosens some of the chemicals Within the same and carries them through theperforat-ions 15 into the mixing spaces 17 between and around the inner receptacles 2. In this connection it is noted that the receptacles 2 are maintained in spaced relation with respect to each other by means of the friction between the outer surfaces of the said receptacles 2 and the interior surface of the barrel ;1 andit is evident further that as sediment is deposited from the water of the boiler, between the receptacles 2 and within the barrel 1, the spacing shapes or mixing chambers 17 are readily maintained between the ends of the receptacles. After being more completely dissolved and mixed for a short period in these mixing spaces 17 within the barrel 1, the now thoroughly dissolved chemicals, and water are carried out through the perforations 13 inthe end plug of the barrel into the boiler. The-interior of the barrel 1, in this way performs the, function of a mixing chamber, where the chemicals are broken down into molecules which are more readily assimilated when they are later discharged into the boiler itself. It is noted in the drawings, thatthe-interstices or spaces 17 between the ends of the adjacent inner receptacles 2, 2, etc, and also the space between the perimeter of the innerreceptacles 2, and the inner circumference ofthe barrel 1, as clearly shown in the Fig. 3 of the drawings, have been made ofconsiderable size for the purpose of affording the necessary mixing space for the chemicals and water, prior to theiridischarge intothe boileritself. The amount of chemical bei'ng used can be controlled by making

asin'an'y perforations

15, and 13, etc., as 1s found necessary-,but

inpractice it is found-only one perforation atlpo1nts14t, and 16"is necessary, while two ,or three at 15 and, 13 give; the best results,

for ordinary sized boilers.

, the device.

In Figs. 5, 6 and 7 I have shown a'rack or crate 18 composedof; four or more longitudinal strips of metal, 19, 2d of thin material preferably, and secured by two or more metal bands 20 riveted to same as shown. At one-end of the rack 18, the strips 19, 2% cross each other as shown dotted at 21-Fig. 7, Whileat theopposite end the strips are bent over as at 22, after the inner chemical receptacles 23 have been placed in the rack injsimilar fashion to that described in connection withthe barrel 1.

It Will'be seen that the charged racklS can "belplaced'i'vithin the outer barrel. 1, as shown in Fig. 5, the purpose of the rack being for convenience in loading andshipping purposes. It will'be understood that periodically the devicehasto be reloaded with inher receptacles -2 and 23 containing afresh supply of chemicals, and the'utility of such a rack as 18' is at onceappreciated.

It is also 1 found that the sediment of muddy waters will settle in the receptacles 2, and assist in clarifying same. This in itself is a minor matter but this feature adds somewhat tothe utility ofthe device as a whole. p p p I have a specially prepared boiler'cornpound which I use inthe holderin soluble form, and the boiler compoundifs dissolved by the entrance and circulation of water in the interior of the holder, so that the solution passing through the perforations will permeate the water in which the device is readily appreciated.

The dispensation of the chemicals from both the inner receptacles2 into the chamber of the barrel at 17, of the properly mixed chemicals and fluid from thebar'rel into the boileritself, may beaccelerated or retarded according to the capacity of the boiler, or the time period in which it is desired to replenish the chemicals of the device, by making a greater or lesser number of perforations in the ends of the inner'receptacles, and the barrel; the methods above described the device canbe adapted to suit the capacity of various boilers,'and to carry a boiler of any certainsizefover any desired time period without replenishing the chemicals in the innerreceptacles of -'I imeperiodsofj a month or more are common withffmy type of' boiler compound holder, due tothe'side 'wallsfof the inner receptaclesan d thej' holder itself forming substantially closed compartments,

therebypreventing the wasting away of the chemicals, commonly occurring when holders having open sides and ends are used. With the latter type constant renewal of the chemicals is imperative, due to the latter not having protection from the direct action of the water, and the water currents within the boiler.

"With my type of holder, the objections above delineated are overcome, and it is seen that I have provided a boiler compound holder of marked novelty and utility for the purpose specified.

What I claim is 1. A boiler compound holder comprising an open ended barrel, perforated plugs for closing said ends, and strips on said ends adapted to fold over and engage against said plugs for locking them in said ends.

2. A boiler compound holder comprising a barrel having closed side walls and open ends, a number of closed receptacles within the barrel, and having perforations in their opposite ends for controlling the flow of liquid therethrough, spaces between and around the inner receptacles within the barrel forming a mixing chamber, perforated plugs closing the ends of the barrel adapted to control the flow of the completely mixed chemicals and fluid through the barrel, and means for locking the said plugs in the ends of the same.

3. A boiler compoundholder comprising an outer open ended barrel, a plurality of inner receptacles having closed side walls and ends, and perforations in opposite ends of the latter for controlling the flow of fluid and chemicals therethrough, perforated plugs closing the ends of the barrel adapted to regulate the passage of mixed chemicals and fluid through the latter, a number of metal strips riveted to the end walls of the barrel adapted to fold over the end plugs and form locking means therefor.

4. In a boiler compound holder having an open ended barrel, perforated plugs of lighter Weight material having inwardly turned flanges engaging against the inner end walls of the barrel, a number of metal strips riveted to the walls of the barrel, said rivets forming a stop for the inner edges of the plug flanges and the metal strips folded over the ends of the said plugs to hold same in'position.

5. In a boiler compound holder having an open ended barrel, perforated plugs of lighter weight material having inwardly turned flanges engaging against the inner end Walls of the barrel, a number of closed inner chemical containing receptacles provided with flow control means, a number of metal strips riveted to the walls of the barrel, said rivets forming a stop for the inner edges of the plug flanges, and the metal strips folded over the ends of the plugs to hold same in position.

6. In a boiler compound holder, an open ended barrel having closed side walls, a number of closed inner chemical holding receptacles in spaced relation with respect to each other, and each provided with means for controlling the flow of liquid therethrough, a rack for holding a series of inner receptacles, slida'bly enterin the barrel, and plugs closing the ends '0 the barrel provided with means for controlling the flow of fluid through the latter.

In testimony whereof I afiiX my signature in the presence of two witnesses.
