This invention relates to devices for physical exercise and pleasure, particularly for childrenvwhere large numbers of them are to be entertained in public parks and school and other playgrounds, and the object of the invention is to provide a strong and durable structure capable of being shipped in sections and assembled and erected by unskilled labor, and a further object is to provide a coaster-slide with a series of waves which will ailord a` corresponding number of thrills to the person using it and finally leave them in an easy sitting posture on the lower end oi' the slide.

l accomplish the above, and other objects which ewill hereinafter appear, by the mech:

anisi'n illustrated in the accompanying drawy) ing, 1n which- Figure l is a perspective view of my de vice comprising a double coaster-slide. Fig. 2 is a vertical section longitudinally of one of the slides. Fig. 3 shows a Jfragment or the slide and middle supporting post and the casting inside elevation for attaching the post to the slide and for uniting' the two portions of the slide which are here joined together. Fig. is a section on the line 4 4 of 3 and Fig. o is a cross section or the slide on the line 5-5 of Fig. Q.

like characters of reference indicate lilre parts throughout the several views of the drawings.

A platform 6 is elevated by tour posts i' to the height from which the slides 8 are to descend, and the posts 7 are continued above the platform to aid in supportingl suitable guard-rails 9. l have shown two coaster slides 8 descending from the platforni in two diametrically opposite direc-- tions, but in many installations in practice, only one slide is used.

A stairway l0, leads from the `ground to the top of the platform and slides and pro.

vides the means for reaching the platform preparatory to the use ot the slide. lt is provided with hand-rails' ll to avoid accidents and also to aid the climber. l have Specification of Letters Patent.

shown three hand-rails il in middle one dividing the stairs l .into two runs for separate use girls respectively.

The slide 8 comprises a pair of risers 9, preferably of wood, which extend 'the full length of the slide and are longitudinally sinuous to impart the desired wave nievernent to the person coasting, and to check his speed and to land him in a com itortable sitting position at the lower end ot' the slide. A series of undulations which vary the speed oi' the coaster and give him a series of thrills, one at each quickening of descent, is more enjoyable than a single glide. l

l, the and platform by boys and ward curves 13, i3 at the upper portion oi the slide and 'a longer downward curve 14. at its lower end, each or' said curves merging into the substantially equal upward curves 15, as shown. lhese upward curves tend to slacken the rate oi' travel of the person coasting, whereas the descent into the downward curves accelerates it.

The lower downward curve lll is much `longer than the two downward curves higher up, and it terminates with sub stantially horizontal portion at the end of the slide, whereby the speed oi the coaster is checked and he cornes to a stop there instead of being violently discharged.

rl`he two risers are connected at their lower curved edges by a sheet ci smooth instal lll, which is nailed thereto and provides a smooth surface down which the coaster glides by direct co 3 therewith. r'liis instal is rein'iiorciul and supported by a wooden door 17 ot' preferably n'ig'ued and grooved boards placed transverzly or' the slide and nailed to thc risers. Sho corners of the slide where the floor joins bound and reinforced by a sheet metal angle-stripv i8, which laps the joints between the risers and flooring and underlaps the slide and is nailed at each longitudinal edge as shown.

The lower end oli' the slide is supported above the ground by legs 2G. at a suitable height to enable a childls toet to reach. the ground by the bend of his knees, when he arrives at the lower end of the slide when coasting1 down it.

About midway of the oit.' the slide provide a pair of post-supports 2l, and' it this location l also p f l' transversely into two 'therefore shape the risers with two downtions :forconvenience in manufacture, stor- 1 age and transportation.' Dowel pins 22 enter the abutting ends of -the joint thus formed, and a plate 23 of cast iron overto receive the end of post 2l. The post 21 is secured by a set screw.

In assembly, the platform 6 can be erected and the upper portion of the slide to and including the posts 21, placed. Then the lower portion of theslide can be readily brought into position with the dowel pins inserted and the joint closed by the aid of a bolt 24 passing through a perforated lug on plate 23 and through a screw-threaded hole in a lug 25 in a plate bolted to the lower riser member, as shown in Fig. 3, and when the joint vis thus drawn tight the bolts securing the plate 23 to the lower riser-memberA may be easily placed. The joint can be kept tight by the'aid of the bolt 24. l

The sheet metal iioor pover 16 is bent down against the edges of the floor at the joint, as shown in dotted lines in Fig. 4, and there held when the vends are drawn togathers The risers for the upper slide member can be cutout of one piece of timber with security but size of the curve in the lower slide member requires the use of two pieces of timber to secure the strength of the grain, and these I unite by a bevel scarf joint 25. As the risers form hand-rests for the coasters I avoid splinters by bending a capstrip of wood 26 and nailing it upon the upper edges of the risers.

The bases of the legs 20 andV posts 21 are embedded in concrete 27, in the manner shown. 1,

' While I have described my invention with more or less minuteness as regards details of construction and arrangement' and as being embodied in certain precise forms,

I do not desire to be limited thereto unduly or any more than is, pointed out in the claims. On the contrary, I contemplate all proper changes inform, construction and arrangement, the -omission of immaterial elements and' the substitution of equivalents as circumstances may suggest or as necessity may render expedient.

1. A coaster slide having a plurality of downward curves and a plurality of upward curves merging therewith, said slide comprising a pair of sinuous risers and a smooth metal covered iioor connecting them, said slide being in two transversely separable members, a socket plate bolted toone member of the slide and havingv an extension overlapping the other slide member, means fixed to said other slidesmember to engage said plate and .draw said slide members together, and a post inthe socket supporting the socket. plate.

2. A coaster slide having a plurality of downward curves and a plurality of upward curves merging therewith, said slide comprising a pair of sinuous risers and a smooth-floor connectingthem, said slide being in two transversely separable members, ,dowel pins in their meeting ends, a metal plate bolted tothe outside of one member of the slide, said plate having an under side post socket and a perforated lug on an 'extension of the plate which overlaps the other slidemember, a second plate with a perforated lug bolted to the last named slide member, a bolt connecting the two lugs to draw the slide members together, means -to secure the plate to said last slide member and a po'st to enter the socket in the plate and extend to the ground to support the slide at said joint.

In witness whereof, I have hereunto set my han'd and seal at Anderson, Indiana, 'this 8th day of July, A. D. one thousand nine hundred and sixteen.
