SPECIFICATION forming part of Letters Patent No. 783,920, dated February 28, 1905.

Application filed November 30, 1904. Serial No. 234,853-

To all whom it may concern.-

Be it known that W8,'GHARLES F. ZIMMER- MAN, HARRY C. ZIMMERMAN, and CHARLES Z M MERMAN, citizens of the UnitedStates, and residents of Araby, in the county of Frederick and State of Maryland, have made a certain new-and useful Invention in Mail or Package Transmitters; and we declare the following to be afull, clear, and exact description of the same,'such as will enable others skilled in the art towhich it appertains to make and use the invention, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification. v

Figure 1 is a perspective view of our invention as applied. Fig. 2 is a side view of the .carrierp and one of the track-hangers. Fig. 3 is a vertical cross-section through the carrier 92, showing oneot' the guide loops or rings k. Fig. 4 is a fragmentary vertical section through one end of the carrier with hinged end or cover open. Fig. 5 is a perspective View of one of the guide loops or rings A, showing the track-wire and pull-cord.- Fig. dis a detail perspective view. Fig. 7 is a perspective view showing an end post and the pullcord connection thereto. Fig.8 is a detail view showing track-hanger connection to post.

The invention relates to means of transmis-I sion for letters or packages; and it consists in. .the novel construction and combinations of parts, as hereinafter set forth.

The object of the invention is chiefly to carry mail-matter from a house to the road along which the postman passes; but it may be used for carrying parcels in stores and for similar purposes wherever needed.

' In the accompanying drawings, illustrating the in vention, the letter a designates the track wire, which is supported by means'of hangers I; from posts a. Along straight courses the posts are provided with arms (Z, from which the hangers 7) depend.

The hanger consists. usually, of a hook e. which is connected to a ring in the arm of the post. To the hook is connected the sheet metal ear f, which is attached by its lower edge portion to the track-wire, as indicated at the body of the carrier.

g. in such wise that said edge portion neatly surrounds the wire, while the thin plate of the ear extends axially therefrom, so that there is on each side of thelower portion of said .plate sufiicient projection of the wire and its covering to provide a lateral track-bearing for the inclined wheels of the carrier.

Where the course is curved, the arm of the post is unnecessary, because the hanger of the track-wire will be held off at an angle by the tension of the track.

The pulling-cord h is guided by the loops or rings A, which are attached to the track wire by means of cylinder connections m, which, like those of the hanger-ears f, provide lateral track bearings. These guideloops are designed to be large enough for the carrier to passthrough them.

Thecarrier 11 is designed to be of cylindrical form, having the hinged conical ends t, by opening which access is bad to the interior.

To the bottom of the carrier are attached the hooks q for the pulling-cord it, which pulls the carrier to inclined position to pass the hangers on a curve of the track. To the upper portion of the body of the carrier the upward and outward inclined arms 1* are secured, and to these arms are pivoted thecarrier-whecls w, whose planes of rotation are inclined to each other at an angle of about ninety degrees, so that their rim-bearings s, which engage the lateral bearings of the track-wire, are inclined to each otherat a similar angle. Between the rims of each pair of carrier-wheels is a small interval which is suificient to enable the wheels to pass the hanger-ears and the guideloop connections without obstruction. construction shown a pair of wheels is provided at or near each end of the carrier-body,

and the wheels of each pair are pivotcd to theinclined doubled arms of the V-form-strap connection .2, the ends of which are riveted to In this manner it is designed to make these inclined arms quite strong andto insure their relative angular position by the bracing angular bend a at the middle of the strap connection.

The pulling-cordh of the carrier is designed to pass at the house end of the course over a in the and around a pulley at the road end-of the course to cause the carrier to move on the trackway.

Gearing may be arranged in connection with the shaft and crank in order to-increase thespeed of rotation of the pulleys if it is desired to have the carrier move very rapidly.

The lower branch of the pulling-cord is designed topass through the small eye-bearings r of the guide-loops and serves to stay them in position.

Having described the invention, what we claim, and desire tosecure by Letters Patent,

1. The combination with a carrier and the inclined slightly-separated carrier-wheels, 0fthe track-wire, its hanger-ears, hangers and supports, substantially as specified.

2. The combination with a carrier, and the inclined slightly-separated carrier-wheels, of the track-wire,-its hanger-ears, hangers and supports, the pulling-cord and pulleys,-substantially as specified.

3." The combination with .a carrier and the inclined'slight]y separated-carrier-wheels, the

track-wire and its hanger ears, of the supports and hangers, the pulling-cord and its pulleys, and the guide-loops for said pullingcord, substantially as specified.

4. The combination with a carrier and the inclined slightly-separated carrier-wheels, the supports and hangers, the pulling-cord and. pulleys, loops, of the track. wire, and its hanger-ears, substantially as speci ed.
