'- TOWER. f

Application filed March26, 1924, Serial No, 701,952,

The present invention relates broadly to towers, and more particularly to towers for use with hoisting -apparatus, such as elevators. I i

j The-purpose of the invention is to provide a tower which is particularly adapted to form the shaft of an elevator employed for raising materials during the construction of a building. A preferred embodiment of the invention is. shown in the accompanying drawings, in which- 1 v Figure 1 is a. perspective view of a tower employed as an-elevator shaft; 4 Figure 2 is a view on an enlarged scale of a portion of one side of the tower;

Figure 3 is a detail view of the top por tion of the tower;

Figure 4 is a detail view showing the connecting means between a corner post of the tower and the base of the tower;

Figure '5 is a sectional plan view on the line V-V of Figure 4;

Figure 6 is a detail v1ew illustrating the coupling means at a joint in the tower;

Figure 7 is a detail view. illustrating one way of adjustably connecting a girt to a corner post of the tower;

Figure 7 is a View similar to Figure 7 showing a slight modification; and

Figures 8, 9 and 10 are detail views illustrating the manner of connecting the elevator guides to the tower. i Our improved 'tower is or knock-downtype and'coniprises ajbase 2,,a top 3 and corner postset, each made in sections, and the usual diagonal braces 5 and horizontal girts 6. a v

Each corner post is composed of a plurality of connected tubular sections and is secured at its lower end to the base 2 in the manner-illustrated in Fi uresl and 5. .The base of the tower is pre erably formed of four I-beams arranged, as, shown,-to form a rectangular frame. At each corner of the frame is a hollow casting 7 adapted to receive the lower end of'a corner postan'd having a flange 8 at its lower end resting upon the upper flanges of the two adjacent I-' beams of the base frame, the casting being secured to said I-beams by bolts 9. Each hollow casting is provided with an' internal shoulder 10 forming a seat for the lowerend of a corner post and each post isfastened of the collapsible in its casting by a bolt llj extending through the castlngand the lower end portion of the post. .Thus it will be seen that the hollow castings 7 form coupling members for the sections of the base of the tower, as well as supports for the corner posts of the tower.

A preferred manner of coupling. two adjacent sections of a corner post is illustrated.

in Figure 6. A plug or spool 12 is inter-" posed between the adjacent ends of the two sections and is provided at each end with a reduced portion 13 to fit into the bore of a section of the post and a shoulder 14 forming a seat for the end of the section. This plug therefore insures exact alignment of the ends of the two sections -of the post. Fitting around the plug and the end portions of the sections'of the post is a sleeve 15, the end portions of the sections being secured in the sleeve by fastening bolts 16 extending through the sleeve and said end portions of the sections. -The braces 5 and girts 6 are of tubular form with, flattened ends and are fastened to the corner posts at the joints thereof b bolts 17 which pass through openings in t e flattened ends ofthe braces and girts in the sleeves 1'5 and are tapped into the plugs 12.-

The top of the tower is also preferably constructed of I-beams connected by hollow castings 7 like those at the base of the tower, these castings having the upper end portions of the corner posts fastened therein. At the top and bottom of the tower the flattened ends of the diagonal braces are fastened to the castings 7 by bolts 18, as illustrated in Figure 4.

At opposite sides of the towerare guides 19 for the lift of they eleyator. areconstructed from angles having a T-section and eachguide is made in sections of a length corresponding approximately to the length of the 'sections'of the corner posts. The guides are secured to the girts 6 of the These guides tower in the mannershown in Figures 8,1)

and 10; Two U-bolts 20 and a plate 21 are employed at each joint, the plate being inter- )posed vbetween a girt and the abutting ends of two sections of a guide, the U-bolts em-- bracing the girt and having their ends extending through openings'in the plate and flanges of the guide sections, nuts 22 being mounted upon the screw threaded ends of the U-bolts, whereby when the nuts are tightened up, the parts are firmly clamped together and the sections of the guide held in perfect alignment by the backing plate 21. The

upper and lower ends of the guides may be secured to the base and top of the tower in any appropriate manner, as by bolts 23.

In erecting a building, a tower of this kind may be setup at any convenient point and the lift employed to elevate materials to any desired height. In order to' facilitateup or down on the corner posts, or removed,

as desired. One way of securing these girtsto the corner posts is shown in Figure? The opposite ends of each such girt are flattened and curved to conform to the curvature of the corner posts, and cooperating curved clamps 25 are removably fastened to such flattened ends by bolts 26. When it is desired to slide a girt 24 up or down, it is only necessary to loosen. the nuts on the bolts 26, or the girt may be removed, if desired, by removing the clamps 25.

In Figure 7 a slightly modified construction is shown in which Ll-bolts 27 cooperate with the curved flattened ends of the girts 2a to clamp these girts to the corner posts.

The stages or panels of the tower will preferably all be made of the same height,.

so that the sections of the corner posts and elevator guides may all be made ofthe same length, as well as the braces and glrts, thus simplifying and standardizing the manufac- Levarer Another advantage of theinvention arises from the provision of a tower of this character which is so constructed as to facilitate the loading and unloading'of materials at different elevations.-

While we have shown and descr bed a preferred embodlment of the lnventlon, 1t Wlll be understood that changes may be made in the various details of construction without departing from the spirit of. the invention or scope of the appended claim;

We claim:

A knockdown elevator tower comprised of sectional corner posts, a base structure in which the corner posts are removably set,

connectors uniting the sections between the corner posts, diagonal and horizontal girts on two sides of the tower having their ends bolted to connectors, sectional elevator guides secured to seine of the girts onsaid two sides of the tower, and horizontal girts on another side of the ,tower clamped to the leg sections thereof between the connectors.

In testimony whereof we have hereunto set our hands.
