SPIRAL SLIDEWAY.

Patented .April 17, 1906.

To aZZ whom it may concern:

Be it known that I, WILLIAM HUME Lo- GAN, a citizen of the United States, residing at Louisville, in the county of J efferson and State of Kentucky, have invented certain new and useful Im rovements in Spiral Slideways; and I do dec are the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, vand to the gures of reference marked thereon, which form a part of this specification.

My invention relates to amusement devices and package-chutes, and has for its object to provide'a spirally-arranged slideway for pleasure seekers or packages to slide down.

A further object of my invention is to pro.- vide a device for these purposes which is particularly simple in its construction, veasy to set up and knock down, safe, strong, and efficient.

With these objects in view my invention consists particularly in the novel spirally-arrarled outside safety-guard.

y invention further consists in the novel central supporting means. p

My invention further consists in certain other details of construction and in combination of parts, which will beirst fully described and` afterward specifically pointed out in the appended claims. i

Referring to the accompanyin drawings, Figure 1 is a perspective view of t e slideway constructed in accordance with my invention.' Fig. 2 is al; horizontal cross-section taken on ine 2 2 of Fig. '1. Fig. 3 is a fragmentary detail view of a part of slideway, 4vertical wall, safety-screen, and outer spiral screen. Fig. 4 is a fragmentary view showing a section of central. stand-pipe and illustrating the slideway directly supported b the outer vertical supports, the vertical wall and safety-screen not being shown. l Fig. 5 is a top plan of the construction shown in Fi 4. l

ike numerals of reference indicate the same parts throughout the several figures, in -which-- 1 indicates the spiral slideway, made of sections or nights 1 and suitably secured to a stand-pipe 2, composed of sections 2', each of said sections having a core 3, Fig. 4, which enters the section immediately above. By this construction the device may be coinpactly shipped and the parts rapidly assembled.

4 indicates the vertical wall, which follows the spiral slideway, to which it is secured, said wall being for the purpose of providing a stiffening for the slideway, greatly strengthening the same and acting to hold the roper curve or contour in the slideway, w `ch is shown, Fig. 3, having its outer edge higher than its inner edge, .said wall preferablynot extending above the edge ofthe slideway.

In Fig. 1 I illustrate a-series of outside vertical supports 5, preferably T-shaped in crosssection, and supportin the slideway 1 by means of the braces or 'brackets 6. Resting on said braces or brackets is a safety-screen 7, which follows the spiral slideway and fills the space between the same and vertical supports 5, which are at a distance and out of reach from the slideway, so that the passeners could not be injured by holding out their hands or arms during their descent, the safety-screen guarding against any one falling over the vertical wal 4. It will be noticed that this safety-screen is made, preferably, of a series of heavy wires or light iron rods 7 which are 'laid spirally upon the braces or brackets 6. This construction is preferable to that of a small-mesh wire, for

the reason that the interstices therein and.

the weave of the wire present a somewhat roughened surface, and would be injurious to the hands, arms, or garments of the passengers, while in my present construction the safety-screen would ofer little or no friction to any object in contact therewith. The

outside spiral guard-wall 8 is constructed simi-v larly to the safety-screen, as shown, and this construction is much more preferable than a cylindrical cage or covering inclosing the entire tower, principally on account of the much lower cost of my present construction and on account of the improved appearance,

and also because it allows a better view of the slideway and its passengers. A suitable passage '9 ,leads to the top of the slideway, and a suitable guard 10 is located at the bottom of slideway to shield any derangement of dress which might occur. I

n Fig. 4 I illustrate a section 2 of the central stand-pipe 2, showing also section of slideway 1 secured thereto.

Having thus described the several parts of my invention, its operation is obvious. The passengers are conveyed by any -suitable ,means to the passage lat the top of the slideway, where their descent is started, and they slide down spirally, making their exit at the bottom of the slideway. This device is particularly adapted also to be used as a package-chute to be used in stores for conveying packages and bundles from one Hoor to another.

What I claim as my invention, and desire to secure by Letters Patent of the United States, is-

1. A. spiral slideway having a central supporting means a safety-screen comprising a series of spirally-arranged wires, said safetyscreenbeing on the outside of said slideway,

and an cuter s iral guard-wall comprising a series of spira ly-arranged wires, substantially as described.

2. A spiral slideway having a central supporting means, a vertical stiffening-wall secured to said slideway, an outer guard-wall constructed of a series ci spirally-arranged wires, and a safety-screen interposed between the said slideway and the saidl outer guard- Wall, said safety-screen being constructed of a series of spirally-arranged wires, substantially as described. y

3. A spiral slideway having adish or curve therein and having a central supporting means constructed in sections, a spirally-arranged vertical stiHening-wall secured to the outer edge of said slideway, the top edge of said Wall extending only to the top edge of said slideway, whereby the dish or curve of the slideway is. preserved regular and unbroken, substantially as described.

4. A spiral slideway having its central supporting means constructed sections, a core 1n each of. said sections arranged to enter its adjacent section, and a series of flights constructed independent of the central sectional 1 supporting means and secured to thel said sectlonal central supporting means, substantially as described. v
