, ATO alwhom 'it may concern: l

Be itknown that I, FRANK R. MCCUNE, av

height may be varied, that is increuisedprI lcitizen of the United States, and resident of St. Louis, Missouri, have vinvented certain new and useful Improvements in Hoisting- Towers, of which the following is a specification containinga full, clear, and exact description, reference being had tothe accompanying drawings, forming a part hereof.

My invention relates to improvements in hoisting towers especially designed for use in connection with a concrete hoistingbucket andl distributing hopper, the` object 'of my invention being to construct a tower cntirely of metalv in such manner'that its decreased,I withoutvarying the transverse A further ob3ect of .my vin-venti'onis tov construct an all-metallic tower, for the pur.

poses above mentioned, that is sectional and may be readily assembled or taken apart without injury to the parts entering into its construction.

For the above purposes myinvention consists incertain novel' features of" constructionand arrangement of parts as will be hereinafter more fully described, pointed outin the claim and illustrated by the aecompanying drawings, in which: Y

Figure 1 is a side elevation offene of my improved towers showing the 'hoisting bucket and distributing hopper therein; Fig.

2 is an end elevation of the tower; Fig. 3 '1s an enlarged plan of the tower, the bucket and hopper being removed; Fig. 4 is an enlarged, detail elevation partly in section showing one of the joints between sections of the tower; Fig. 5 is asectional plan taken on the line 5-5 of Fig..4;'Fig. `6 is a perspective illustrating the angle irons for joining the corner posts; and Fig. 7 is a perspective, similar to Fig. 6, and illustrates the relative positions ofthe ledgers and stay rods relative -to the angle irons for joining the uprights. y Y

Referring by numerals to the accompanying drawings: V1 designates l.shaped uprights constituting the corner posts ofthe tower.

2 designates the central uprights which may be interchangeably 'used to facilitate the erection of. the tower, it not being necessary to number the uprights as required when a special upright is designedor one. use only. c L 'f 3 designates the side ledgers and 4 the end ledgers, all of whichare L-,shaped, the side ledgers being of one length and the end ledgers of a lesser length.v lCoinciding perforations in the uprights and ledgers permit the employment of bolts 5 for securing the ledgers to the u rights. f y. 6 designates -shaped connecting plates secured to the outside faces of the uprights and 7 designates angularplates secured to the. inside faces of the uprights, thev plates 'lV being of less length than the plates 6 as shown in Figs. 6 and 7.' By this arrangement-.itis vobvious that when a second set of uprights are to be vsecured in posit-ionthe litting of the second upright to the first upright is greatly facilltated. Each of the plates 6 is perforated adjacent each of its ends to receive the bent Vends of the stay rods 8. The ends of the stay rods opposed to theirv bent ends are threaded and ,turn buckles 9 are threaded thereto.

Removably secured to the uppermost ledgers 4 are the channel bars 10 between which are pivotally mounted the pulleys 11,

` and removably secured to a pair of the ledgers 3 are the beams 12 arranged to slipport the hopper 13.r Bearings are detachably secured to one ot' the ledgers 4 and a pulley 15 iscarried thereby.

1- designatesthe track rails, preferably of T-iron which are vertically disposed in the tower and arranged in oppositely facing pairs as shown in Fig. 3. These track rails are substantially the same length as the uprights and are secured by bolts to the ledgers 3 as shown in Fig. 5. i f 17 designates a tilting bucket arranged, to slide between one pair of the track rails 16 ,and be operated by a cable 18 vto which is attached a'hoisting apparatus (not shown).

In setting up a tower, a section, the length of thel uprights, is assembled, as shown, with the lowermost ledgers in an inverted position relative to the vbalance of the ledgers and a concrete bed 19 is filled in around the lower ends of the uprights and said inverted ledger, thereby lirmly and securely holding the tower in position. The length of the up-v uilding story which, I have found to-be about twelve feet, thus, it is obvious that the sections of the tower are Asuiiicient to raise4 the tower one story at a time, and that after each' of the walls of the building are completed, one story at a time, the rails 10 andbeams 12 are 'tted to the added section oftower. l

In a tower built accordin to my invention, the operations of assemb ing and taking apart are greatly facilitated in that there is no fitting or cutting of parts required. Heretofore towers of this class have been constructed mostly of Wooden timbers requiring accurate fitting and cutting, which tlmbers, after being employed just a few times in the construction oftowers, would be unfit for use again by reason of the numerous spike and bolt holes necessary in their structure.

While I have illustrated and described my improved tower as being double, for the purposes of holding a hopper and a dumping bucket, it is obvious that, without departing from the spirit of my invention, the track rails 16, which are shown as seimaeee ...cured to the side ledgers, may be securedto.

tbeend ledgers and, when so secured, only a single pair ot tracks are used and that the intermediate cross ledgersmay he dispensed vcrossed adjustable stay rodconnecting di- -agonally opposite pairs of said plates servu t ing the double function of trus'singthe, eni tire structure and holding said ledgers in .place between the ends of the upriglits.

In testimony whereof, l have'sigaed'-myV name to this specification, in"pres|ncefo two subscribing witnesses.. .Y 4
