To all. whe/m, may concern.' Be it. known that I, JOHN S. Srmnwrxr, Jr., a cltizen 'of the United States, and resident of yMilwaukee in the, county of Mib waukee. and Statelof Wisconsin, have invented cert-ain'new `and useful Improvements in Carriers;.and I do hereby declare thatthe tion thereof.

M y invention consists lnwhat .1s herein particularlyset -forth with reference to the' mcornpanyin drawings aid pointed out in thefciaims o this. specification,- its main obf -ject beingl .to provide for economic rapid transportation of mail matterbetwecn sta-- tions- A Figure 1 of the .drawings represents a partlytransverse section view of an electric.

' line and carrier in. which my improvements a f between stations, and the ends of each cross aref'embodied," the section being indicated by line `1-1 in the next describe Fig. 2,"a 'side elevatic'm` of the same partly in s`ection,"the view being indicated by line 2-2' in Fig-1, and Fig. 3, a sectional view of a 3-3 in Fig. 1

fragment of the carrier indicated byline Referring by numerals tothe drawings, 4.

indicates o nefof -a'seiies of posts and 5 a cross arm of the same. A cap 6 of .each post terminates ina seatjfor a track-wire 7 arm are in connectionwith an velectric-current line wire'S.. Astraddle of the4 track- -wire are tractiontrolley-wheels@ 10, hung in. a carrier, which carrie'r is constructed to clear the posts and cross arms thereof. The carrier is also constructed to provide' compartfr'nnts in Whichito store mail matter or other material 'for transportatin, side openlngs to the compartmentsof-said carrier be;

' ing closed'by doorsll.

The axle 12- of the tract-ion trolley-wheel 9-has its bearings in a braclret 12 depending into a central spacel'of the carrier adjacent Q o one end of the same, and the axle 13 of the trolley-wheel` 1 0 has its bearingsy in gearcases '14 of said carrier,- there being two-of these cases, l0ne eachsideof the track-wire 711pon whichfsaid trolley-wheels' travel. -In

eachv gear-case va spur-pinion 15 is fast 0n -the trolley-.wheel axle 13, and lin meshwith gear-cases. Fast on the spindle 17,- intermediate of the' gear-cases.' 14' is a. wormcarrier, is, a 'spiral-spring 2 illustration; I
