SIGNORS, BY MESNE ASSIGNMENTS, TO THE JAEGER MACHINE COMPANY, OF

COLUMBUS, OHIO, A CORPORATION OF OHIO TOWER Application filed December 9, 1927.. Serial no. 238,800.

This invention relates to towers, such as are used by contractors in connection with the hoisting and distribution of concrete or other material, and it has particular reference to sectional steel towers and certain details entering into the construction thereof.

Towers of the type referred to are adapted to be erected on different jobs, being dismantled and moved from one place to another as conditions require,'and are exposed to all sorts of weather conditions. As a result of this exposure the bolts which hold the members in assembled relation frequently become rusty so that their removal is rendered very ditficult and requires an undue expenditure of time and labor.

An object of the present invention isto provide a tower which can be readily assembled and disassembled, and one in which the securing members arev protected from exposure to the elements.

Further objects and advantages to be de rived through practice of the invention will become apparent from a perusal of the following specification describing a preferred embodiment thereof. taken in connection with the accompanying drawings illustrating the invention. wherein- Fig. 1 is an elevational view illustrating the upper and one of the intermediate sections of our improved tower, the horizontals and diagonals of only one side of the tower being shown;

Fig. 13 is a horizontal sectional View taken I of sections, each comprising four uprights or columns 10 arranged in square formation and secured in spaced relation by means of girts 11, the structure being reinforced by means of diagonal braces 12, hereinafter termed diagonals, arranged on all four sides of the tower. Each of the sections is about twenty feet in length and when assembled includes approximately four girts on each side with pairs of diagonals arranged, as illustrated Figs. 1, 7, 8, 9 and 10, between adjacent girts on each side of the tower. be noted that the girts on one pair of diametrically opposite sides of the tower are arranged at a slightly different level than are the corresponding adjacent girts on the other pair of diametrically opposite sides, as clearly shown in Figs. 7, 8 and 9. Elevator guides 13 are provided on two opposite sides of the tower, being secured to the girts midway of the ends thereof in a manner to be described presently.

In some instances it is found desirable to use two elevators side by side, in which case six uprights or columns 10 are arranged to form two squares, the middle tier ofgirts carrying elevator guides for both shafts, as illustrated in Fig. 3.

As hereinbefore stated, trouble has been experienced in loosening the bolts which secure the different members, due to corrosion of the threaded portions, which has often resulted in great loss in time and labor in the dismantling of the tower. With the view to the elimination of such disadvantages, we have illustrated in Figs. 1, 7, 8, 9 and 11 the It should improved means which our invention provides for securing the girts and diagonals to the columns.

Referring particularly to Fig. 11, each girt 11 has its ends closed by means of a plug 17, having a reduced portion 18 which enters the end of the girt and is spot welded or other wise secured thereto at one or more points. The plug 17 is formed with a centrally disposed threaded aperture 1'? which is flared outwardly at its outer end to facilitate the proper starting of the bolt therethrough. The end of the plug is also formed with an are shaped transverse concavity 17 corresponding to the outer surface of the column 10. At the points where the girts are to be secured the columns 10 are provided with diametrically aligned apertures 20 adapted to receive bolts 21 which are passed therethrough and which enter the threaded apertures in the plugs 17 in the ends of the girts, the recesses 17 fitting snugly against the columns and the flared threaded portions serving to guide the bolts into proper position- The diagonals 12 are formed with flattened end portions 12 which are apertured to receive the bolts 21, a pair of diagonals being carried by each bolt adjacent the head thereof and between the head of the bolt and the column 10. A diagonal is secured to each of the bolts 21 at the top of the tower and extends downwardly diagonally across its respective side of the tower, being secured to the next lower belt of the other column 10 of that side. Of course, the intermediate bolts 21 each form the securing means for two of the diagonals, as illustrated in Figs. 1, 7, 8 and 9. As previously stated, the horizontal girts on one pair of opposite sides of the tower are at a slightly diflerent level than are the corresponding girts on the other pair of opposite sides with the result that the bolts 21 pass through the tower in pairs, the bolts of each pair being disposed at right angles to each other with one bolt located above the other (see Figs. 1, 7, 8, 9 and 10). It will be appreciated that only the heads of the bolts 21 are exposed, the threads being entirely protected so that even though the structure may stand for an indefinite period no trouble will be experienced in loosening the bolts when desired.

In Figs. 3, 4, 5 and 6 we have illustrated the manner in which the elevator guides are secured to the horizontal members or girts. The guides 13 are formed of sections of tubular metal, the sections being of such length that the joints therebetween always fall opposite one of the girts. Each of the guide sections has secured to one end, preferably by welding, a curved plate 22 having a threaded aperture in alignment with a similar aperture adjacent the end of the guide. The plate 22 is of such length as to project beyond the end of the guide sectionand into the next succeeding section of the guide. It

is, of course, necessary that the inner opposed faces of the guides be uninterrupted so as to form a track for the elevator, and to this end the securing means is located inside the tube which forms the guide. The guide is spaced relatively to the girt by means of a spacer 23, which consists of a short tubular member having its ends cut away so as to engage snugly the girt and the guide respectively. Bolts 24 are passed through aligned apertures in the girt, the threaded portions entering the threaded apertures in the plate 22. Thus each section of the guide-way is locked securely to the preceding section until the desired height is reached, and as in the case of the girts and diagonals the threaded portions of the bolts are entirely protected from exposure.

In the double shaft construction, that is to say where two shafts are erected side by side, the middle tier of girts support elevator guides for both shafts in a manner now to be described.

Referring particularly to Figs. 3 and 4 of the drawings, which illustrate the means for connecting the guides in the double shaft structure, the numeral 25 designates a member formed preferably of cast iron metal and comprising portions 26 and 27, each being provided with an arc shaped outer surface 28. The portions 26 and 27 are off-set with respect to each other and are provided with apertures adapted to receive bolts which extend into the threaded apertures in the plates 22 and serve the double function of securing the guides to the girts and locking the guide sections in assembled relation.

It is necessary to provide landings for the elevators at certain points along the shaft and at these points, as a measure of safety, socalled landing panels are secured. One of these panels is illustrated in the lower portion of Fig. 1 of the drawings, and the means employed in the mounting thereof is illustrated in Fig. 12. The landing panel comprises a rectangular frame having braces extending diagonally from its corners at opposite ends. The panels are secured at their ends to the columns 10 by means of U-bolts 29, which embrace the columns and extend through apertures formed in a flange member 30, having a reduced portioni3l which enters the end of the tubular horizontal frame member 11?) and is preferably spot welded thereto.

After a sufiicient number of sections have been joined together to give the desired height to the tower, a top section is mounted thereon, as illustrated in Figs. 10 and 13. The top section is relatively short and includes posts or columns 32, similar to the columns 10, each being surmounted by a cap 33 for preventing moisture from entering the ends of the columns. The cap is secured in position by means of bolts passing through i...

aligned apertures in the column and the cap. The top section is provided adjacent its upper end with rails 32a formed of channel iron, which extend entirely around the tower and are secured to the columns 32 by means of U- bolts 34 and also by means of bolts 35 which are passed through aligned apertures in the columns and the web of the channel. Reinforcing plates or bars 86 positioned between the channel and the columns provide a rigid bearing between these parts. The lower ends of the column 32 are provided with sleeves 37 (shown in dotted lines in Fig. 10) which extend into the tops of the columns 10, so that this section may be readily lifted out when it is desired to dismantle the structure.

It will thus be apparent that our invention provides a tower which is extremely simple in construction, which may be quickly and easily erected or dismantled, and one in which the threaded portions and members are so positioned that they are not subjected to exposure to the elements.

Although preferred embodiments of the invention have been illustrated and described herein, it should be understood that the invention is susceptible of various modifications and adaptations within the scope of the appended claims.
