I The construction of the conveyor involves a plurality of suitably spaced posts ‘I and the , “The principal object ofvthe invention is1topro¢ "roadway post 8. At the building 5 a suitable vide. aymail conveyor of the=character stated support or bracket 9 has the drive means gen which/can be easily controlled ‘for transporting erally referred tobyz'numeral l 0 mounted thereon mail from the point of depos‘itby the mailman to‘ the house without any inconvenience. and in a rapid and ‘fool-proof manner. ' ‘ Still another important object-of the invention ‘is to provide a mail ‘conveyor of the character lstatedl'which is substantially automatic in oper ration. These and various other important objects and advantages of the invention will become apparent 20 to the reader of the following speci?cation. In the drawings:-—- 7 Figure '1 represents a side elevational view of the apparatus.

Figure 67 is a top plan view of the pulley and mount at the roadway end of the conveyor. IE2. _As is. ‘shown in Figures land 6, the post 8 has the elongated plate i3rsecured to the top thereof and into this plate I3 can be driven the threaded studs or screws 14, these studs or 15 screws passing through the slot I5 01’ the shank iii of the yoke I‘? in which the pulley I8 is mounted. Obviously, by loosening and tighten .ing these studs or screws Hi the shank Hi can be adjusted on the plate l3 for regulating the tautness of the cable I!) which is trained over the pulleys ll-—l8. Figure 8 is a section on‘ the line 8-—8 of Fig ure "7. ' Figure 9 is an enlarged side elevational view of the mail receptacle. ' Figure 10 is a sectional view on the line [0-40 of Figure 9. ' . Figure 11 is an enlarged edge elevational view of one of the pulleys. 45 Figure 12 is a top plan view of the drive means and control therefor. Figure 13 is a side elevational view of the structure shown in Figure 12 with a portion 50 broken away. Figure 14 is a perspective of the cable operated arm. Figure 15 is a sectional View on the line [5-45 of Figure 12. 55 7 Referring to the drawings wherein like numer ' It will be observed in Figure 11 that each of the pulleys‘ is provided with an anti-slipping cover 20, preferably of rubber, so that the ovate 25 shaped enlargements 2l—22 on the cable l9 can easily pass thereover. These enlargements 2 l-22 are at substantially diametrically opposite points ' on the cable. Numeral 23 generally refers to the mail recep 30 tacle which‘ is an elongated rectangular-shaped box 24 open at each end and provided with a hinged closure 25 at each end adapted to be held in closed position by suitable spring latch Figure 7 is a side elevational view of the cable . means 26. showing one of the‘ enlargements thereon. 10 and this includes apulley ll onthe driven shaft Obviously, the mailman uses one of these closures in gaining access to the box 24, while the person receiving the mail uses the other closure in gaining access to the box for retrieving the mail. A U-shaped member 2'! is secured to the top of the box 24 and has eyes at the upper ends of its leg portions denoted by numeral 28 to which the ends of the cable are secured as at 29. A pair of strap members 30-30 extend up wardly from each side of the box 24 and converge 45. over the box and then further extend upwardly as at 3!. Each of these portions Si is equipped with a roller wheel 32 for riding engagement on the horizontal ?anges 33 of the inverted T-beam 50 34. (See Figure 4.) As shown in Figure 2, each post ‘I has a U shaped framework 35 secured by its end portions to the posts as at 36. Inside of the frame 35 is the small square 55 52,108,453 frame 31 an upstanding shank 38 of which is se cured as at 39 to the upper leg of the frame 35, while the depending shank 40 has the straps a—a thereof spread apart as at b to straddle the up standing ?ange of the beam 34 where it is secured as at 42 to the beam, thus suspending the beam in a substantially horizontal position as shown in Figure 1. The mail receptacle 23 is supported on the thus supported track as suggested in 10 Figure 2. The drive means consists of the box-like struc ture 44 through the end portions of which the driven shaft I2 is journaled. Upon the platform 9 is mounted the electric 15 motor 45 the armature shaft 46 of which is con nectible with the driven shaft 12 by the clutch generally referred to by numeral 41. This clutch 41 is provided with the collar 48 with whichthe yoke 49 is engaged; this yoke depending from the 20 slide bar 50 which is slidable through the guides 5I—5! on the box 44. A horizontal rockable arm 52 is pivotally mount ed on the post 53 and has a laterally disposed por tion 54 at one end to avoid the pulley II. This 25 lateral portion 54 is provided with the slotted ?nger 55 through which the cable I9 extends. The remaining end of the arm 52 is provided with the cam 55 abutting against the plate 5'! 30 on the adjacent end of the slide bar 50. Switches 58—59 are provided on the dielectric panel 60 and these have the arms (SI-62, respec the motor and connect the clutch 41, while in its reverse movement the cam 56 releases the plate 5‘! to disconnect the clutch and open the motor cir cuit simultaneously. Thus the box 23 is stopped automatically at the end of the trackway 24. It can be seen in Figures 2 and 3 that guide means is provided for the cable, guide rollers 63 for the upper ?ight of the cable, while an elon gated roller 64 is mounted on the lower leg of each frame 35 for guiding the lower ?ight of the cable l9. , While the foregoing speci?cation sets forth the invention in speci?c terms, it is to be understood that numerous changes in the shape, size and ma 15 terials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter. Having described the invention what is claimed as new is: 20 An article carrier of the character described comprising an endless cable, drive means for said cable, spaced pulleys over which the cable is trained, supporting means for said pulleys, a post, a trackway supported by the post, a receptacle 25 attached to the cable and mounted for longi tudinal movement on the trackway, a frame-like structure on the post through which the recep tacle is movable, said frame-like structure being provided with a depending portion supporting 30 tively, rising therefrom and in the path of the the trackway, said depending portion provided with a loop-like structure, said loop-like struc arm 52. These switches 58—59 are for the motor 45 which is reversely wound so that as the en ture serving as a guide for one ?ight of the largement 2! or 22 strikes the portion 55 of the arm 52, for operating one of the switches to start cable, and anti-frictional means in the said loop like structure for said cable. 35 GUY SPENCER.
