. DEVICE FOR namo'rma s c'rIoNAL STEAM on HOT-WATER CAST-IRON BOILERS on THE LIKE.

Application filed Ju1y 1, 1924. Serial No. 723,608.

To all whom it may concerm j Be it lmown that I, ROBERT T. Wrrrrnns,

a citizen of the United Strtesyresiding .at

facturers to furnish,as'part of aboiler,- rods upon which the boiler sections are erected."

' Ordinarily these rods are provided. at one end, with an enlarged head and are additionally provided with a collar having set screws for forcing the boiler sections co-- gether. In assembling boiler sections with these devices the work is slow and tedious the method being a cumbersome one as after each boiler section is set in place it is necessary to put on the collar with the set screws" and tighten the enlarged head down to draw the sections together. It is thennecessary to loosen the set" screws in the collar and remove the same thereafter'placing another I boiler section in place and repeating the before-mentioned operation.

In erecting boilers the sections are given" a water-tight connection through the use of short tubes called push-nipples which provide a connection between the. interiors of 40 the several sections. The. sections arethen pushed or forced together over the push nipples squeezing these nipples into the apertures in the boiler sections thus providing a steam and Water tight joint be-,

4 tween thesections.

Having in mind the slow and cumbersome methods-now used in erecting sectional boilers, I have invented the-device hereinafter described and set forth in the accompany in drawings and specification.

I)ne of the objects of my invention is to provide a, device of simple construction specifically a slotted rod adapted to receive 7 which is adapted for use in assembling the sections of boilers, radiators orthe like. Another ob e'ct of my invention is to provide a novel construction of rod and wedge for assembling sectional boilers, radiators 'or the like. I I ;A still further object of my invention is to provide a device for the purpose descrlbed WhlCh is cheap and simple of manu- '-facture and highly eflicient in operation.

' Other further objects novel features of construction and improved results of my invention will appear in the following description and accompanying drawings.

In the drawings: Figure 1 1s a View in elevation showing the manner of erecting the boilerQthree of the sections having been assembled.

Fig. 2 is a View in vertical section showng the manner of using and applying my inventlon. r

' v Fig. 3 is an enlarged detailed View showing the wedge receiving openingof the rod. Fig. 4 is a detailed view" showing the wedge inserted'through the rod-opening.

Referring to the several parts which constitute my invention as shown in the accompanying drawings, 5, 6 and 7 represent the several sections of a boiler or radiaton Wlll of course be readily understood that the heating device can be constituted'of as many sections as 1s deslrable or as is necessary to accomplish the desired result. In the case of boilers the same are'supported on a uitable base 8 which is-common to constructions of this character. I

Sectional boilers or radiators are furnished withtie or assembling rods atboth their upper andlower ends. I have desig nated these rods by the numeral 9.

p The rods which I have provided however are of a particular construction. These rods 9 are screw-threaded at their'ends to receive the nuts 10 which carry in front of them the enlarged washers 11 or the like. These rods are provided of course .of a

' length to assemble a specified numberof sections. The rods shown in Fig. 1 are for assembl'mg a boiler having eight parts.

Ata plurality of ointsv intermediate the rods they are provided with openings 12 which are spaced apart a width equal to the width or thickness of the boiler sections. One wall of these openings 12 is tapered as designated at 13 so that the openings are of a size and shape to receive the wedge shaped pins or keys let.

Referring now again tothe boiler sections it will be seen that these sections are provided with apertures 15 adjacentboth their upper and lower ends. In the assembled boiler the contacting apertures of the sections are joined together by the push nippl'es1f6so' as to make water or steam tight joint between the sections.

In assembling the sections the nuts 10 and washers 11- are removed from one end of the rods and one of the, boiler sections is placed on the base 8. The rods are then inserted throughthe apertures in the upper and lower ends otthis section so that the washers 11 of the rods abut the outer face of this section and prevents the rod from being pulled inwardly through the opening 17 of the section, as clearly appears in Fig. 2 of the drawing.- a

Before the next section is placed the push nipples 16 are inserted inthe aperture 16 of the section. It will be seen that one half of the nipple extends outwardly beyond the opening. In placing the next section it is necessary to force this outstanding portion of the nipple intothe aperture of the section so that the faces of the two-sections w ill abut.

This is accomplished by the use of the wedge or'key 14. The wedge is placed in the tapered opening 18 of the rod behind the section which it is desired to force over the n'ipplef By driving. the wedge into the rod opening the boiler section will be pushed forward over thepirsh nipple until this section racefirm ly abuts the face 01 the first section" which has been put in place.

To erect the entire boiler it is only requiredto repeat the operation which is described.

If it is desired the rodsmary be withdrawn after "the assembling of the boiler has been completed and a set of; solid rods substituted" in their place. By substituting the solid rods myimproved slotted rods could then be used for assemblinganother boiler. However if-desired my slotted rods can be used as the permanent tie rods of the boiler 01 radiators In many instances my rods would probably be used as the permanent tie rods as their cost is not much greater than the cost of the ordinary solid rod and the saving in time by leaving them in as the permanent rods would probably offset the small saving accomplished by removing them and using them again when assembling another boiler.

In other instances'it would be necessary to use my rods as the permanent tie rods as theboil'er' 'orf'urnace room-in which the-turna'ce is erected would not be large enough to permit the rods to be withdrawn once the boiler had been erected. As my improved rods would be the proper length of the completely erected boil-er this of course would be permissible and the rods would be finished OK at their out'er'ends witlithe'usual bolts 10 and washers 11, before mentioned. The operation heretofore described can if desired be reversedto a certain extent." If desired after the first boiler section is in place the nuts 10 and washers 11 are removed from the end of the rods and" the wedge or key 14 inserted in the second aperture in the rod. The second boiler section is then placed on the base andthe'rod inserted through the two sections. To dra'w the second sect-ion intopl-a'ce it is" only necessary to again place the wasliersltand nuts" 1'0 'on the ends of the rods and: tighten dbwnthe nuts 10 until the secon'd' section; isdr'awn into place. A slight tal with afhai'nme-r or the like on v p then release the pressure of the nuts 10 sothat they can bebacked ofl handandthe rod removed from the sections so that the third section can be placed upon the base and drawn upinto place "i'nthe manner described in respect to the second boiler section. p

From the foregoing it will be seen that I have provided a device by whicl1"secti'onal boilers or radiators canloefii i'ucli' more rapidly and easily assembled than has been done heretofore. It will also be seen that the cost of my assembling device is very cheap, so cheap in fact that if desired my slotted rod can be used as the permanent tie rod for the completed boiler" orra'd'iator.

Having thus described my invention what I claim and desire to secure by Letters P'at 1. 18. device for assem bli'ng a sectional boiler or the like, comprising a tie' rod adapted to be assedthrou h sai'd sections, said tie rod carrying means intermediate the length of the ti e-rod for forcing the sections together. v I
