OLIVER O. JOHNSON, OF WINDOM, MINNESOTA.

MAIL-TRANSPORTATION SYSTEM.

Specification of Letters Patent.

Patented March 5, 1907.

Application filed June 27, 1906. Serial No. 323,664.

Minnesota, have invented certain new and useful Improvements in Mail-Transportation Systems; and I do hereby declare 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.

This invention relates to elevated carriers for transportating mail-matter and is designed especially for the use of persons living along the route of mail-carriers in rural districts.

The particular improvements consist in the construction of the hanger for supporting the cable-wires and the trackway and of the carrier itself, which passes through the hanger.

With these and other objects in view the invention consists in the construction, com

bination, and arrangement of parts, all as hereinafter fully described, pointed out in the claims, and illustrated in the accompanying drawings, it being understood that slight modifications and changes may be made in the size, shape, and material of the several parts and in other minor details within the scope of the claims and without departing from the spirit of the invention.

In the drawings, Figure 1 is a side elevation of a mail-transporting device constructed in accordance with this invention. Fig. 2 is a vertical sectional view on the line 2 2 of Fig. 1 looking in the direction of the arrow.

Fig. 8 is a bottom plan view of the hanger. l

Fig. 4 is a longitudinal vertical section through the carrier. tral section through. the hanger, taken approximately 011 the line 5 5 of Fig. 1. Fig. 6 is a side elevation of a modified form of the bottom plate for the hanger.

Like parts are designated by similar numerals in the several views.

Referring to the drawings, 10 designates the terminal post at the delivery or post-ofice end of the line, and 11 designates the post at the house end of the line, the latter being located adjacent the door of the house of the party using the line. Between the posts 10 and 11 is shown an intermediate post 12, carrying a hanger 13 for supporting the cable-a ires and trackway, as hereinafter re- Fig. 5 is a vertical cenferred to. In practice a plurality of intermediate posts and hangers may be used, but

as all are identical in construction the de scription of a single one will apply equally to the others. The hanger is fastened to its post by means of a metal strap 14, bolted thereto, as shown.

The delivery-post carries at its upper end a grooved pulley 15, while the house-post 11 carries a similar pulley 16, each of which is provided with a crank-handle 17, a rope or cable 18 passing around said pulleys and having its ends connected to the mail-carrier, as hereinafter described.

Attached to the terminal posts 10 and 11, between the upper and lower stretches of the cable, is an elevated trackway 19, likewise formed of rope or cable, and upon which the carrier 20 travels.

The hanger 13 is provided with a roller 21, journaled in an opening provided for that purpose in its upper portion, and has attached to its under face a bent rod 22, curved, as shown in Fig. 2, and provided with a grooved roller 23, upon which the lower stretch of the cable 18 runs, the upper stretch thereof in like manner being carried upon the grooved roller 21. The lower portion of the hanger is enlarged, as shown, and is provided with an opening 24 of sufficient extent to permit the carrier 20 to freely pass therethrough. The lower end of the hanger is provided with oppositely-facing shoulders 25, rounded, as shown, there being a space between the shoulders, (designated 6,) in which the trackway 19 fits, being retained in place therein by means of a plate 26, pivoted thereto and movable on the under face of the hanger. The outer end of said plate is provided with a curved shoulder 27, while the inner end is formed with a pair of projecting lingers 28.. Attached to the outer side of the hanger, as shown in Fig. 1, is a leaf-spring 29, the lower end of which extends below the hanger, engaging with one side or "the other of the shoulder 27 of the supporting-plate 26 to hold the same in one position or the other.

The carrier 20 consists of a body portion 30, having the upwardly and oppositely inclined ends 31, a shank 32 connected to said body portion, and a receptacle 33, carried by the shank and in which the mail-matter is received. The body portion is formed with an opening 34, through which the trackway 19 passes, there being a pair of grooved wheels 85 carried in the interior of the body portion within the opening 34 and running upon said trackway. Owing to the size of the opening 34 through which the trackway passes, there will obviously be some play oi said trackway when the carrier passes through the opening 24 of the hanger, due to the raising of the carrier as its inclined end 31 passes 1 over the shoulders 25 or the hanger, which 3 are curved in cross-section to a'll'ord easy passage thereover. To retain the trackwa in place against the periphery of the rollers 35 during this elevatioi oi the carrier, there is provided a third interior wheel 36 in the body portion of the carrier, which will serve vided with. an opening adjacent its lower end to hit the trackway during the passage of the carrier through the h force the trackway ar wheels 35, retaining the tract therein and prover during the elevation oi the ca '1 he width of the body port; rier is such that the plans 32 is directly in line with the ope: ing 8 between the shoulders 25 on the lower end oi the ha:.-. .ger, so that when the shank moves through said opening on the passage of the carrier through the hanger the plate 26 will lie directlv the path oi the shank, with ore of its lin 28 extending across the 0pc... 6, as SliOWIL in Fig. 3. 'lhe shank will theieiore contact with the adjacent i' ger, s. the plate slightly to one side to pein'nt its passage r-opeirmg, a2. st the gooves iii the i 111 place through the 01161- 11g, when the sprii g 29 will again lock the plate in POSltiOli with the other finger across the opelniig 6. 01 the return trip of the ca; r the same actio;t.s will be made by the shank and plate, as the plate is i'ieely movable lfl both directims, owing to its pivotal fasten ig, and may thus be said to reciprocate across the under face of the hanger.

The-ends of the cable 18 are attached to a roller 37, carried by the carrier-shz' ik b -1;- termediate its ends, a: d upon rot .1 ol the cable 111 either direction the ear ier Will be struction of bottom plate for the hanger.

This plate 38 ismade of cast-iron and is pro- ,vided with the curved upper portion 39 and ears 40. In use the formation of the shoul ders 25 will be obviated, as the opening 24 of ill extend completely through 1 ing and pulleys connected to the upper and lower portions of said hanger to sur port the the hanger I the lower end thereof. Two plates therefore will be used, one upon each leg of the hanger, attached thereto by bolts passing through. the ears ll), with the curved portions 39 opposite each other, there being a slight space any slipping theieol to permit the passage of the carrier therethrough; means adjacent said opening for supporting said trackway; a rod connected to the under .iace of said hanger and provided with a pulley for supporting the lower stretch of said cable and a pulley connected with the j upper portion oi said hanger for supporting 1r 1, i ii oi tue caithe upper stretch of said cable.
