T0 oil whom it may concern:

Be it lrnown that l, "i /murder A. Concern, a citizen of the United States, residing at Garden City, L. l, in the county of Nassau and Eitate of New York, have invented certein new and useful improvements in Truck- Siupported Knockdown Circle-Swings, or which the following is a specification, refer ence being; had therein to the accompanying drawings.

This invention relates to a truck-supported knockdown circle swing, and has for its obj -ct the provision of comparatively simple and efficient means for assembling the sections of? a tower, or taking down or disas senihling the sections placing or positioning these sections preferably upon a platform or a body of inotor truck. 7

Another object of the invention is the construction of an apparstusthat embodies peculiar and e'fiicient IEQRIIS for producing quickly assembled and disassembled parts upon a motor truck tor suspending swings or boat-like hodi-s upon 2. motor truck for amusement purposes.

"J'Vith these and other objects in view, my

invention comprises certain .novei cornhinations, constructions and arrangements of ports will be hereinafter described, illustrated in the ac'corn)anyingdrawings, and more particularly pointed out in the appended claims.

In the drawings:

Figure 1 i a view in side elevation of an eppa 'atus constructed in accordance with the present invention, the hoisting frame for elevating and loweringthe sections being removed.

2 a top plan view of the motor truck, showing the sections of the tower disassembled, or resting upon the platform of the truck, as they appear in transportation.

Fig. 3 is a view in side elevation of the tower, with the hoisting; apparatus attached thereto, showing in dotted lines the position of the sections upon the platform. as well as the manner of lifting or elevating; the sections and placing the some in position, one above the other, to produce the sectionel tower.

Fig. 4.- is perspective view of one oi. the sections of the tower.

'F is a perspective frame.

Referring to the drawings by numerals, 1 designates the truck, and 2 the platform view ot' the hoisting thereof. T sectional tower 3, carried by the platform 2, comprises the base section l, the intermediate sections 5, 6, and 7, and the top section These sections are detachable, being held together, 9, by removable plates of any ordinary tructure or arrangement, as l lllitlIQ no claim to these plates 9.

ilpon removing or detaching the plates 9 (F l and 5), the sections can he stacked one within the other, as shown in dotted lines in 5, or the sections can be elevated into place upon the manner: The hoisting frame 10 includes a body having a large opening 11, through which the sections rnav swing from the dotted position shown in 5 into the position shownin full lines, the sections losing arranged one above the other. The lower end oi the ia e 10 is provided with oreclrets l2, and a pipe 18 is securedat its ends within these U'shaped brackets 12; rotataolv mounted upon the pipe This a pair of supporting hooks 15:; these hooks are hooked over an edge 15 (nice. 5 snd o), detochably supporting; the frame upon a section ofthe tower. To the eve-bolt 16 is secured a pol icy if, and passed over the pulley is a hoistrng" le 18; the inner end of the cahle is tied ound the top or the section that is to he llnbed in place or lowered, as desired, and the outer end or": the cable is grasped by the operator, or may he connected to the drum of a windlass, as desired. An anchor rod 19 is connected, its upper end, to the top of the frame 10, and the lower end or the rod is connected to an anchor chain 20, which chain is suitably its tened to the section that has alreadv been secured in place; by slackinc; up on the anchorchain 20, the hoisting frame ca swing; out over the sections on the platform 2 to he lifted, then the inner end oi the hoisting cable can be attached to a section and the section lifted and swung through the opening 11. into place upon the tower, then the plates 9 are fastened in position. and the sections thereh v assembled. To disassemble or knock-down the sections. the plates 9 are removed in order and through the use of the hoisting cable 18. the anchor rod 19 and chain 21 and the hoisting frame 10., each section can be lowered, one at a time, and stacked in a nested position upon the platform 2, as indicated in full lines in Fig; 2 and in dotted lines Fig. 5.

From actual experience I found that my truclr, in the following which this invention relates, during the 'ex-' tensive manufacture of the same and 1, therefore, reserve the right to make such alterations or changes as shall fairl fall within the scope of the appended claims.

7 What I claim is:

1. In an apparatus of the class described, the combination with a sectional tower, of a hoisting frame provided with hooks, said hooks attached to said tower and permitting the hoisting frame to be removed against the towel" or swung, at its upper end, away from the tower, a pulley and a hoisting cable attached to the upper end of the hoisting frame,,said cable adapted to be attached to a section of the tower for lifting and swinging the section through the hoisting frame for positioning the section, and anchoring or holding means attached to the frame and a portion of the tower.

2. In an apparatus of the class described, the combination with a sectional tower, of a hoisting frame including a body provided with an opening, and with U-shaped brackets on its lower end, a pipe in said brackets, pivotally mounted hooks on the pipe, an

eye-bolt attached to the upper end of the body above the opening, said hooks adapted to engage the side of a section for holding the hoisting frame in a pivotally mounted position upon the tower, a pulley and a hoisting cable supported upon said eye-bolt, said hoisting cable adapted to be attached to a section for raising or lowering the sec tion by moving the same through the opening, an anchoring rod attached at its upper end to the upper end of the body, and an anchoring chain attached to the lower end of the anchoring rod and adapted to be attached to; a portion of the tower for securing the hoisting frame in different hoisting positions with respect to the tower, substantially as shown and described.

3. In an apparatus of the class described,

the combination with a support, of a hoisting frame detachably connectedat its lower end to said support, said hoisting frame pro- 'vided witha comparatively large opening for allowing a section of a tower to pass therethrough, means attached to the hoisting frame and to the support for retaining the frame indifferent adjusted positions with reference to the support, and means attached to the top of the frame having a portion adapted to swing through the opening and be attached to a sectionfof the tower foradjustingthe section or raising or lowering the same with respect to the support.

In testimony whereof I hereunto affix my signature.
