I These angular flanges have in their edge-porplates 11 and screw-bolts 12. This fixation I ensures at the same time that all prejudicial bending moments acting upon the chimney are transformed into axial tensil or compressive stresses.

In chimneys ofthis 'ype the inconvenience makes itself felt which is due to the freely exposed upper flange, that destruction by rusting begins at the connecting joints of these flanges as shown in 5. The upper edge of the chimney is therefore covered by a ring 13 designed to protect it against rain. Thisring'13, which is loosely mounted, consists of a flat ring, bearing on the. upper edge of the chimney and of two

extensions

14 and 15. Fhe outer extension 14 isconical and designed to keep the; rain-water away from the chimney and the inner cylindrical extension 15 is cylindrical and of such length that no rain-water can get at the inner surfaces of the upper. portions ofv the iron-plates of the I chimney.

On the chimney shown in Fig. 1,- which is cylindrical, a platform 1 6'is mounted so that it can be raised and lowered. This platform 16"has a guard-rail 17. On the lower surface of the platform 16- double angular pieces 18 are fixed between which, on cross-bolts 19, grooved guide-rollers 21 are rotatably mounted. These guide-rollers roll with their grooves20 on the websof the longitudinal irons 8 (Figs. 6 and 7)'-so' that the hoisting and lowering of the platform can be carriedv out free of disturbances;

With regard toeach longitudinal iron the platform is fitted with two parallel "hearing pieces 22 being arranged in radial direction and formed for journalling a transverseiaxle 23 on which two bars 24 are loosely mounted. In the free ends of every two bars 24 a screwbolt 25 is fixed by means of which these bars 24 can be fixed on the webs of the longitudinal bars 8 by inserting the screw-bolts 25 through corresponding holes 26 of said longitudinal bars. For each longitudinal bar of the chimney one bearing piece 22' with oscillatablc bars 24 and screw-bolts 25 is provided. Any number of holes 26 may be provided in the longitudinal bars, according to the distance between the different working positions in which the platform is designed to be held on the chimney.

Lugs 28 are arranged on the upper edge of the chimney or on arms 27 extending from said upper edge, saidlugs being designed for pulleys blocks 29 hooked at the other end into come I sponding eyes 30 on the platform.

The movable platform presents the advantage that it may be used already at the buildwhen it is constructed,

as will be hereinafter by means of which the sections, designed for building the chimney can be hoisted to be swung to above the section which has been fixed in position. The freshsection is then lowered on the fixed section. I After the two sections have been connected the one. with the other by means of screw bolts 6, the blocks and tackles are detached and suspended again in the lugsofitlieuppen edge of the section which has been last put in position. After releasing" the platform by removing the screw-bolts 25, the platform can be hoisted again to be secured in the fresh position so that another'section canbe put-on.

When the chimney isfinished,,theplatform I remains the upper position, securedon the longitudinal bars 8, as shown in. Fig, 1'. The blocks and tackles mightbe removed to be stored to prevent premature destruction by weather and'wind.

up the blocks andtackles and hangsthersame on the upper edge.ofthe chimnemwhereupon the'platform may be lowered to; the: ground after thefix ationz-me ans have. been removed,

so thatthepainters". and the material can. be hoisted on theiplatform. to the top of the chimney. The chimney is painted as: usual from the top-end towards the bottom end.

After the painting the platform is hoisted to the top-end of the chimney and. secured in this position.

At the building of iron-plate. chimneys it has been found that-the outer circumference of the chimney is not accurately cylindrical, and that the circumferenceof the chimney is not regular from the topto the bottom so that the guide-rollers of the loaded; platform might not securely and uniformly bear against the longitudinal irons; The arrangements shownin Figs. 9- to 11 are signed to avoid this inconvenience; The platform 16 has on its lower side as many radial guide bars '31 as the-re are longitudinal irons on the chimney,- the central webs of said guide-bars bearing on guide-rollers 32, mounted in double brackets3'3 guided by means of rollers 34 onv the longitudinal irons 8 of the chimney. The brackets 33 are'preferably double so that the

rollers

32 and 34 can be mounted between the two brackets on rest loosely on the outer edge of the platform.

I For securing the platform in its-position the I free end of the arms 37 are fixed to the corid I responding longitudinal irons 8 by means of screw-bolts engaging with the holes 26 of said longitudinal irons.

The hoisting and lowering of the platform is effected, as mentioned above, by mean-s of blocks and tackles 29. A platform with the arrangements shown in Figs. 9 to 11 will be pulled downwards in its secured position by the weight of the brackets, wherefrom results an inwardly directed weight-component, by the action of which the rollers 34 of the brackets are constantly pressed tightly againstthe longitudinal-irons 8 so that any undesired turning of the platform is excluded and the work can be carried out securely, even when a strong wind is blowing and when the outer diameter of the chimney is irregular.

I claim 1. An iron-plate chimney composed of several sections forming together a cylinder, comprising in combination with the sections consisting each of several elements, longitudinal T-irons fixed by rivets in the joints of said section-elements, a platform surrounding said chimney, means for guiding said platform on said longitudinal T-irons, and means for securely fixing said platform on said chimney at any desired height.

2. An iron-plate chimney composed of several sections forming together a cylinder, comprising in combination with the sections consisting each of several elements, longitudinal T-irons consisting of profiled irons having holes in their web fixed by rivets in the joints of said section-elements so that they project radially over the outer surface of said sections, a platform surrounding said chimney, means for guiding said platform on said longitudinal T-irons, and means for securely fixing said platform on said chimney at any desired height.

3. An iron-plate chimney composed of several sections forming together a cylinder,

7 comprising in combination with the sections consisting each of several elements, longitudinal T-irons fixed by rivets in the joints of said section-elements, a platform surrounding said chimney, means for guiding said platform on said longitudinal T-irons, means for securely fixing said platform on said chimney at any desired height consisting of brackets fixed on the lower side of said plat form, pairs of link-arms rigidly connected to the lower side of said platform, a pair of guide rollers in each pair of arms adapted to run on said T-irons, and a pair of links connected to each pair of brackets adapted to be connected to said T-irons for securing said platform on said chimney at any desired height.

4;. An iron-plate chimney composed of several sections having flanges, screws connecting the flanges of the several sections, longitudinal T-irons fixed on said sections connected with each other and covering the longitudinal joint of said sections, a platform surrounding said chimney and having radial slots, pairs of brackets fixed on the lower side of said platform, rollers in the lower end of each of said brackets running on said T- irons, rollers mounted freely rotatable near the upper edge of each bracket in the horizontal plane and designed to guide said platform, radial bars on the lower side of said platform resting upon said pairs of rollers, pairs of links hingedly mounted on said brackets and upwardly projecting through said radial slots of said platform adapted to connect said brackets to said T-irons and for automatically adjusting said platform in radial direction.

5. In an iron plate chimney composed of several sections forming together a cylinder, in combination with said cylinder composed of sections consisting each of several elements, longitudinal T-irons fixed on the joints of said section-elements having holes at suitable points, a platform surrounding said chimney and having radial slots and an aperture for a winch-rope, brackets connected to the lower surface of said platform, link-arms pivotally connected to said brackets and extending through said radial slots in said platform, and means for fixing the ends of said link-arms in said holes ofsaid T-irons.

In testimony whereof I afiix my signature.
