Specification of Letters Patent.

Patent ed June e, 1908.

Application filed Julyl, 1907. Serial No. 381,729.

To all whom it may concern: Beii known that-I, CARL STIELER, a citizen'of the United States, and're'siding at Chi:

cago, in the county of Cook and'State of Illi- 1101s, have invented a new and useful 1111-.

grovement in M old's for"Tapering Chimney onstructions, oflwhich the following is a com lete s ecification. q

s invention relates to molds for tapering chimney constructions, and more particularly to an adjustable mold by means of which the thickness as well as the diameter of the chimney may be regulated within certain limits. The object of this invention is to provide a -mold for concrete chimney constructions which is adaptedto be adjusted by removing or inserting segments thereof, so asto'vary the diameter of the chimney to meetthe requirements ofthe construction.

'It is afurther object of the invention to provide a simple construction adapted to be readilyset up or knocked down for filling and for removing from the completed section of the chimney.

Another object of the invention is to-provide a mold, which while it isjcollapsible, af-

fords when assembled a very rigid construction capable of holding its shape under the strain caused in operation.

The invention consists of the matters here-- tion. Fig. 2 is a fragmentary, top p an view of the same with parts removed. i fragmentary view of the shells showing one half thereof in elevation and the other. half in is a fragmentary, top plan view thereof.

Fig. 7 is an end view of one of the air space forms. Fig. 8 is a section taken on line A A of Fig. 7. Fig. 9 is an enlarged artialsection taken on any of the lines B- of Fig 2.

Fig. 10 is an enlarged section taken on.

of the segment sections of the mold, and Fig. 12 is a fragmentary elevation of the same.. i As shown in said drawings: a supportingv frame is. provided in whichthe mold is sup Fig. 11 is a plan view of one' ported and which may be of any preferred construction and material but, which as shown, comprises a pair of up er and a pair of lower concentric rings of cl iannel iron or other suitable material and indicated respectively by 1-1 and 1 1 Connecting the two outer rings and the two inner rings of said pairs are the uprights 2, which may likewise be of channel iron if referred, and the outer ones of which are rigidly bolted to the outer side of the rings 1 and 1 and the inner-ones to the inner sides of the rings 1 and 1 as shown more clearly in Figs. 2, 5 and 6. The

upper'ends 2 of said uprights 2 are bent transversely and across the rings to which tudinally as is shown in Figs. 2 and 6. Corresponding upper and lower rings may be of the same size if preferred but as shown the upper ones are of less diameter than the lower ones and a block 2 of woo'd or other preferred material is inserted between the flanges of each rin and the uprights are bolted therethroug and through the rings. The molds are adjustably supported between the outer and inner rings of said frame and comprise anouter and an inner shell 3 and 3., each constructed of tapered segments extending lon itudinally thereof, and which, vif preferred, tliough'not shown, may be constructed of varyingwidt-hs, so that the shells may be increased or decreased in diameter in varying degrees .by inserting or removing a 'segment or-segments of the desired sizes. Each of said segments comprises a transversely curved plate of sheet metal 3 havin on its outer side an n per, lower and centra pair of slide rails in ioated respectively by 3 3 and 3 Each of said rails comprises a barrigidly engaged by bolting or riveting to the plate, transversely thereof, and having onits outer edge a lon 'tudinal flange turned towards the other ar of the same .pair, thereby forming a slot opening into a channel beneath saidflanges. A connecting rod or bar 3 extends longitudinally of each plate on 'theouter side thereof and is rigidly engaged per and lower of; rails thereof by the adk or other preferred material is inserted in the justing bolts 5a1id 5. Inasmuch as all of said bolts are of like construction'a descrip- A threaded socket 6 is provided for each. bolt and has a bracket 6 thereon which is pivotally engaged to one tion of one will sul'lice.

of the rings ofthe supporting frame, thereby allowing the socket to swing about its pivot as an axis. The bolt, as 4, has threaded engagement in ,the socket and the head 4 thereof is inserted between the adjacent pair of rails, as 3 where it engages beneath the flanges of said rails. Said bolt is provided witlra collar 4?, which ma y be engaged on the bolt in any preferred manner in close cont-act with the rod or bar 3", so that as the bolt is turned in its socket it acts to move the shell or the segment if the segments are not connected' together. As shown, joint plates 7 overlap the joints between the segments, on the outer sides thereof, and are bolted to the plates 3 thereby firmly connecting them together. Said shells are further supported by means of hangers 8 which are adjustably engaged in the slotted ends 2 of the uprights 2 and have their lower ends bent at right angles and provided with a head 8 adapted to engage between the upper rails The operation is as follows: The support-j ing frame is set up and segments of the proper widths to form shells of the desired circumference are mounted thereon by means of the adjusting screws and their sockets and the hangers 8. Said bolts arethen turned to bring the segments into proper position where they are secured together by the joint plates 7. The concrete 9 or other plastic material is then poured between the shells and allowed to set, when the mold may be removed by removing the-segments separately or by simply removing one segment.

from each shell and then drawing the. remaining portion of the shell out of contact with the concrete by means of the adjusting screws, when it may be lifted away.

I If preferred, and as shown, air spaces may be leftin the concrete and for this purpose a collapsible form comprising U shaped sections 10 and 10 is provided. The flanges of said sections overlap and are bolted together asjshown in Fig. 7, and a wedgelO of wood shell to hold it in shape.

Obviously the diameter of the shells may be varied by inserting or removing segments, and by.varying the taper of the segments the taper of the chimney will be varied. Obviously also various details of construction may be varied without departing from the principles of my invention.
