PAT NT OFFICE HERBERT H. GRUBB, or BARAIBOO, Wisconsin, ASSIGNOR TO HUMANE STANGHION worms, or BARABOO, WISCONSIN, A CORPORATION on WISCONSIN SWING Application filed January 27, 1930. Serial No. 423,610.
This invention relatesto an improvement in swings of the type in which a plank or swing board is pivotally supported at spaced invention is to simplify and strengthen a swing of this character, to enhance its capacity to afiord healthful and exhilarating recreation and exercise for children, and to minimize the possibilities of the users of the swing being injured.
Other objects and advantages reside in certain novel features of the construction, ar-
rangement and combination of parts which will be hereinafter more fully descrlbed and particularly pointed out in the appended; j claims, reference being had to the accompany-w .1
ing drawings forming a part of this specification, and in which:
Figure 1 is a view in end elevation showing a swing constructed in accordance wlth the present invention;
Figure 2 is a view thereof in longitudlnal vertical section taken in the plane of line 2-2 of Figure 1;
Figure 3 is a detail view in vertical section taken on line 33 of Figure 1, parts being shown in elevation for the sake of illustration Figure 4 is a detail view in horizontal section taken on line 44 of Figure 1, with parts shown in elevation for the sake of simplicity in illustration; and
Figure 5 is a similar view taken on line 55 of Figure 2.
Referring to the drawings it will be seen that the swing embodying the present invention includes a pair of spaced supports or end frames designated at 1 and 2 and of inverted U-shape. The end frames 1 and 2 are of identical construction and, as clearly shown in Figure 1, each has spaced vertical legs 3 connected by an integral arch-like upper portion 4. Suspended from each end frame or support is a U-shaped hanger, the hanger suspended from the end frame l-being designated at 5 and the hanger being suspended from the end frame 2 being designated at 6. The hangers 5 and 6 are of identical construc- ,tion and each'has spaced side rods or hanger rods 7 connected at their lower ends by an integral andhorizontally disposed connecting portion 8. The horizontal portion 8 of v each hanger is engaged beneath spaced portions of, a swing board or plank 9. Bearing straps 1O embrace the horizontal portions of the hanger rods below the swing board and are connected to the swing board by means of fastening devices 11 thereby pivotally interconnecting the swing board and the hangfers. The upper ends of the spaced side rods of each hanger are pivotally connected as at 12 to connecting brackets 13 clamped and otherwise suitably secured to the arched portions of the supports 1 and 2.
The supports 1 and 2 are braced and strengthened by means of longitudinal connecting rods 14, there being one such con- Jnecting rod 14 at each side of the swing.
Each connecting rod 14 is alined with the legs 3 of the end frames 1 and 2 with which it is associated and is fastened at its ends to these legs by the fittings 15 shown in detail 15 is of two-part construction, the parts being adapted to form a socket 16 for the end of the connecting rod 14 which the fitting recei'ves. Bolts and nuts 17 secure the parts of each fitting 15 together and to the leg 3 of the frame with which it is associated. Braces 20 are provided betweeneach leg 3 of the supporting frame and the adjacent portion of the rod 14 connected thereto, these braces 20 being extended at an angle as shown in Figure 2 and being connected to the rod 14 and to the legs 3 by bolts and nuts 21 and connecting fittings 22 as shown in detail in Figure 5.
The arched type end frames 1 and 2 are each constructed of a single piece of metal and may be tubular. This end frame construction has substantial inherent strength and when the end frames are suitably interconnected and braced a very rigid and durable construction is provided. Further than this, the arched portions of the end frames are utilized to directly pivotally support the hangers for the swing board and as a consequence the swing board and the hangers,
