TRANSPORTATION SYSTEM.

. Specification oi' Letters Patent. vApplication led June 12, 1998. Serial No. 438,069.

Patented March 30, 1909.

i To all whom it may concern:

B'e it known that I, WILLIAM O. CARR, a citizen ofthe UnitedStates, residing at Buffalo', in the county of Erie and State of New York,`have invented a certain new and useful Im roved Transportation System, of which t e following is a specification. I

This invention relates to an improved underground system of transportation, which is. preferably designed for use in carrying mails, packages,etc.

The object of the invention is to provideA a 4 very strong t andw comparatively cheap conduit which 1s reinforced at intervals by metal reinforcements which are embedded in the body of `the conduit and have rojections extending into the interior of tiie conduit which serve as supports for the rails, constituting. the' track upon which the car travels.

TheI invention also relates to certain details-of construction which will be hereinafter describedand claimed, reference being had t0` the accompanying drawings in which a .preferred structureof the invention is shown.

Figure 1 is a transverse section through the underground tube of the im roved system, the section being taken t rough the concrete wall, the support for the ralls and the? railsalso4 showing a front elevation of` the car. Fig. 2 is a longitudinal section on a reduced scale through a portion of the underground tube of the improved system on line a a, Fi 1showing a side elevation of the car in p ace upon the rails. Fig. 3 is an enlarged' fragmentary verticalsectionon line b b, 4 through one of the rail supports and a rail, showin the method of securing thel rail thereto an supporting it therefrom. Fi 4 is a transverse section through the ra4 support showing a plan view of the rail fastening.` F' 5 1s a fragmentary inside view of one o the rail supports and a rail secured thereto.

In referrin to the drawings in detail, like numerals designate like parts. This improved system which is to be installed at a suitable distance beneath the surface of the ground consists of a tube of circular, oblong or other desirable form in cross section, metal reinforcements for the said tube whichv are embedded at intervals in the tube body and rails which are supported from the ,metal reinforcements.

The body 1, of the tube is of concrete or' other suitable material and has a series of metal reinforcements embedded therein and extending completely around the same in a transverse direction and forming encircling loop reinforcements. These reinforcements are each preferably constructed in two sections 2 and 3 which are joined at the top and bottom res ectively by bolts 4 or other fasteners whic extend through abutting lateral end flanges of the sections. v

- The sections about midway of their length are enlarged to form lateral inwardly extending members which project through the inner wall of the concrete body into the interior of the tube and constitute supports to which the rails are fastened. These su ports are preferably of the form shown in 3, 4 and 5 consisting of an inwardly extending portion-6, a vertical flange 7 extending u ward from its inner end and a transverse y extending strengthening web, 8, which extends between about the middle of the flange and the inner surface of the reinforcement connecting at its bottom edge to the' portion 6, and serving as a stiffening and strengthening bridge.

The rails 9 are preferably of angle form in cross section and are fastened to the supports by bolts 10 which pass through the vertical flanges 7 of the supports and the vertical portion of the rails.

A horizontal ledge 11 is formed on each sup ort which extends inwardly from about the ower end of the flange 7 and extends beneath the vertical portion of the rail serving to support the same', see Fig. 3.

lnsulating'iber or similar non-conducting material is fitted between the vertical portion of the rail and the flange 7 and ledge 11 of the support'as shown at 12 in Fig. 3 and cach bolt 10 is also surrounded by a sleeve 13 of insulating material .which enlarges at one end to form a washer 14 between the nut of Athe bolt and the outer surface of the fiange 7, see Fig. 3.

The car adapted to travel on the rails is preferably of the conventionalA form described in my Patents Numbers 831,263 and 851,649 granted September 18th 1906 and April 30th 1907, respectively to which reference it to be had for a more extended description. This car is of lskeleton form having a frame 15 upon which a package carrier Q. einser 16 is mounted end from which e series of indiyiduei muil boxes 17 ere detechebiysupported.

An electric motor i8 is inounted directly upon one or both exles 19 oi the csr end is driven by electric ower teken froml the under surface ci the orizontel ortion of the angie reiiby s suitebie trolley w eel 20.

rihe reiis ere elec'tricoily energized from eny -suitable source of electric power.

The chief edyenteges of this im roved system reside in the greet strength lo structure obtained, coupled with moderete cost of construction und the utilization of the loop reinforcements to support the rails.
