To aZZ whom, it may concern: 7

Be it known that I, JAMEs R. HARRIS, a citizen of the United States, residing at OX- ford, in the county of Butler and State of Ohio, have invented new and useful Improvements in Mail-Delivery Apparatus, of which the following is a specification.

This invention relates to a mail-delivery apparatus especially adapted for rural free delivery uses.

The primary object of the invention is to provide simple and effective apparatus for conveying mail-matter from a roadway or route to a dwelling at a distance therefrom or from such dwelling to the roadway and dispose the mail-matter in convenient location for access either by a postman or an addressee, and thus enable persons remote from a roadway to dispose mail-matter within easy reaching distance of a carrier or messenger, the apparatus being entirely under the control of the owner, who may at any time draw the receptacle to its starting-point.

The invention consists in the construction and arrangement of the several parts, which will be more fully hereinafter set forth.

In the drawings, Figure 1 is an elevation of a portion of the apparatus, showing the bracket used on posts disposed in alinement. Fig. 2 is a sectional elevation showing the bracket in a plane at right angles to that illusrated by Fig. 1 and also a portion of the post and the mail-receptacle. Fig. 3 is a front elevation, partially broken away, of the ap p aratus. including the mail-receptacle, as illustrated by Fig. 2. Fig. 4 is an elevation of the post and remaining part of the apparatus at the delivery-terminal. Fig. 5 is a sectional elevation of the operating mechanism for the apparatus, located at the receivingterminal and under the control of the user. Fig. 6 is an elevation of one of the posts and brackets, showing a variation in the structure to accommodate slight curves in a straight-line series of posts and wires. Fig. 7 is a perspective view illustrating one of the posts and a decided curve structure. Figs. 8, 9, and 10 are detail views of different parts of the apparatus.

Similar numerals of reference are employed to indicate corresponding parts in the several views.

The apparatus comprises straight line means wherein at intervals may be disposed curve structures to accommodate the traverse of the conveyer in both direct and curved lines from a point adjacent to a road or a dwelling to places of mailing and delivery, respectively, and the apparatus may extend over any distance, the movement of the conveyer being at all times under the control of the occupants of the dwelling.

The numeral 1 designates a post simulating an ordinary telephone or telegraph pole of any suitable height, and a number of these posts will be arranged at intervals be tween a roadway and a dwelling, either in straight lines or irregularly disposed, as may be found necessary. Each post in the straight-line series of the posts has a bracket secured thereto and projecting outwardly therefrom, this bracket comprising a horizontal member 2 with an outer terminal drop 3, provided with an inner upturned extremity 4, which serves as a post and has a rail 5 attached thereto, to which a track wire or cable 6 is secured by clamps 7, the op osite extremities of the rail 5 being braced with respect to the bracket through the medium of a U-shaped brace or reinforcing device 8. The inner portion of the horizontal member 2 continues into an attaching member 9, which is firmly secured to the post 1, as shown by Fig. 2, and has an outwardly and downwardly inclined hanger member 10 continuous with a pulley-support 11, which in turn is provided with an outer upwardly-directed guide 12, having a vertical terminal 13. T o the upper portion of the horizontal member 2 and terminal drop 3 thereof an upwardly-inclined brace 14 extends and is secured to the postof pole 1, as at 15, and continued beyond and above its point of securement and shaped to provide a pulley-support 16. Within the pulley-supports 11 and J 16 grooved guidepulleys 17 and 18 are respectively mounted to engage upper and lower portions of the operating-wire 19, the pulley 17 having guards 20 depending over opposite parts of the upper portion thereof to always insure the disposition of the lower portion of the operating-wire 19 thereinto and avoid the passage of such wire down between the sides of the pulley and its support. The pulleys 17 and 18 are immovably supported by the portions of the bracket in which they are located, it being unnecessary in straight-line series of the posts to have these pulleys adjustable. As will be hereinafter explained, however, these pulleys may be adjustable to accommodate curves in the line.

The bracket just described is adapted for straight lines or straight runs of the wire or cable 6 but where slight curves are encountered and it is necessary to change the direction of the wire or cable 6 a modification in the guide-pulleys 17 and 18 is necessary, and, as shown by Fig. 6, the horizontal member 21 of the bracket is given a quarter-twist to present a vertical flat side and is provided with a plurality of openings 22. The support 23 for the lower sheave or pulley 24 in this instance has an arm 25 continuing from the inner member thereof and provided also with a plurality of openings 26 to coincide with the openings 22 of the horizontal member 21 of the bracket. The arm 25 may be adjusted at any angle desired and is held in its adjusted position by a clamp 27, as shown in detail by Fig.8, and comprising three partsnamely, a bolt 28 and two

members

29 and 30, having radial ribs 31 on their inner opposing faces, which are adapted to interlock when the two parts are brought in close engagement to prevent accidental movement of one part on the other after adjustment has been made. The extremities of the

members

29 and 30 opposite the extremities having the ribs 31 are respectively formed with grooves 32 and 33 to receive the arm 25 of the support 23' and the horizontal member 21 of the bracket, the bolt 28 acting as the clamping means when tightened to hold the

members

29 and 30 of the clamp in close engagement and also firmly secured to the arm 25 and bracket member 21. The clamp as an entirety is movable longitudinally on the bracket member 21, so as to vary the distance of the pulley 24 inwardly and outwardly with respect to the post on which. this modified form of the bracket is held. The support 23 in this instance also has a hinged guard 34, which may be adjusted at any angle in view of the fact that it is proposed to connect the same to the outer member of the support 23 by a suitable knucklejoint, which may be tightened or loosened, as desired and as indicated at 35. The upper inWardly-inclined brace 36 of this bracket is similar to that shown by Figs. 1 and 2 but the upper terminal of said brace, as at 39, is turned outwardly from the post or pole and has the upper pulley-support 38 connected thereto by a knuckle-joint 39", similar to the joint 34 heretofore described, the joint 39 being readily operative to loosen or tighten the same and hold the support and the pulley therein at any angle desired. The bracket, as shown by Fig. 6, is similar in all respects, except the particular changes of structure herein set forth, to the bracket illustrated by Figs. 1 and 2, and these brackets will be used with those shown by Figs. 1 and 2 at points where a slight deflection or curve of the wire 6 and a corresponding change in the direction of the portions of the operating-wire 19, engaging the pulleys at the upper and lower portions of the bracket, may be required.

Fig. 7 illustrates a bracket structure to accommodate a decided curve or Where it is necessary to change the direction of the wire or cable 6 at a positive angle with relation to the remaining portion thereof. The bracket 40 in this direct-curve structure is essentially the same as the bracket shown by Figs. 1 and 2, with the changes which will now be set forth; but in this instance a duplicate of the bracket or two of the brackets are secured to a single post in planes at right angles to each other, and a third bracket 41, somewhat shorter in length, is disposed in the same horizontal plane and attached to the post midway between the other two brackets or at an angle of forty-five degrees to the others. Each of these brackets has a member extending outwardly, as in the before-described bracket, and at the terminal of said member is a vertical drop 42, continuing into a horizontal member 43 at its lower extremity, and the member 43 terminates in an inner vertical attaching end 44. At its inner portion the member 40 of each bracket extends vertically downward, as at 45, and provides a securing means for the complete bracket, suitable fastenings beingpassed through the vertical portion 45 into the post or pole. From the vertical portion 45 an arm 46 extends outwardly and serves as a rest for a bar 47, which is curved similarly to thetrack, which will be more fully hereinafter explained. The one end of the bar 47 is down wardly deflected, as at 48, to facilitate movement thereonto of a portion of the conveyer. Depending from the horizontal outwardlyprojecting top member of the intermediate bracket 41 is a hanger-arm 49, having its lower terminal directed inwardly and then rebent in an outward direction to provide a pulley or sheave support 50, which is secured on the bar 47 and has therein a horizontallydisposed pulley or sheave 51, as clearly shown by Fig. 9, the pulley or sheave 51 having outer guards, as at 52*, to prevent the wire from passing in between the ends of the said sheave or pulley and the support tliere.

for. As many of these pulleys or sheaves 51 may be arranged on the bar 47 as desired, and in some instances it will be preferable to locate one under each of the upper horizontal members of the brackets, so as to provide an effective antifrictional guide for the lower portion of the operating-wire engaging the same. The advantage of having these pulleys or sheaves 51 attached to the bar 47 in the manner specified is that the small operating-Wire 19 is held taut in going around the curve and does not pull the conveyer side- Wise. Secured to each of the inwardly-extending horizontal supports 43 of the drop members of the brackets is the lower flange of an outwardly-curved or arcuate rail 52, which is of reverse L shape in cross-section, and. the inner upstanding or vertical flange of this rail has the ends of the track-wire 6 connected thereto. This rail 52 may have an extent as great as is demanded by the nature of the direct curve required at the point where such rail is used or as may be necessary to change the direction of the trackwire either to a full right angle with respect to some remaining portion of said. wire or to a less degree. By disposing and attaching the rail 52 as set forth and shown by Fig. 7 the use of bolts or rivets in the path of movement or in close proximity to the plane of movement of the conveyer is obviated, and hence there is no obstruction to the movement of the said conveyer in rounding the curve. To the inner depending vertical end 44 of each bracket a flat guard-rail 53 is secured and has the same arcuate contour as the rail 52 above, the ends of this guard-rail being directed or turned upwardly, as at 54, to meet or be in close relation to the ends of the rail 52 for a purpose which will be hereinafter explained. The upper inwardly-inclined braces 56 of the several brackets terminateat their upper ends in supports 57 for horizontal pulleys or sheaves 58, which are engaged by the upper portion of the operat ing-wire, as many of the pulleys or sheaves 58 being used as found necessary to guide the wire with the least possible friction around the post or pole.

At the delivery end of the route and included in the apparatus means are provided for extending the track-wire, and consists of a bar 59, of steel or other suitable metal, extending across and bolted to a post 60. At each end when a carrier is used on each side of the line the track-wire 6 is attached to a common fence or other suitable ratchet 61, which is adapted to tighten the said wire. Held on the post 60 in operative relation to the bar 59 is a horizontally-disposed grooved guide pulley or sheave 62 for carrying the opcrating-wire 19 around the post 60. By the use of the parts just explained at the terminal of the apparatus the conveyer will be movable into convenient reaching distance by the mail-carrier or postman, and also at this end of the line the track wire or cable may be tightened, as may be found necessary.

Fig. 5 illustrates mechanism for actuating the small operating-wire 19 at the residence or dwelling end of the line, and it consists of a suitable casting 63, secured to a post 64 and supporting shafts 65 and 66, respec tively, having fixed on opposite terminals thereof a grooved pulley or sheave 67, which is vertically disposed, and an operating-wheel 68, provided with a crank-handle or analogous device 69. On the extremity of the shaft 65 opposite that carrying the grooved pulley or sheave 67 a pinion is fixed and meshes with a spur or analogous gear 71, fast on the shaft 66, and by operating the drive or crank wheel 68 and the shaft 66 the shaft 65 is set in motion and the pulley or sheave 67 caused to revolve and correspondingly move the operatingwire 19, which engages the said pulley, and by this means the conveyer may be caused to traverse the track-wire 6 and the rail devices carried by the several posts in opposite directions in accordance with the direction of rotation given to the pulley or sheave 67. The crank-wheel 68 operates as a fly-wheel and need not be used in all constructions of the apparatus, but is particularly advantageous with a long stretch of the line in that it will require less labor or power to move the operating-wire.

The conveyer embodies a carriage 72, having therein deeply-grooved track-wheels 73, which engage the track-wire 6 and the track-rails of the brackets. These trackwheels 73 are inclosed by the carriage 72 and held in perfect alinement. The carriage 72 is preferably formed from a single piece of sheet-steel bent to form an inclosure and having the lower portion thereof turned downwardly and inwardly, as at 72, and also flared outwardly to guide the carriage onto the rail 5, in view of the fact that it may be swayed by the wind or motion in traveling back and forth, and when the carriage comes up to or is about to reach the bracket these flaring edges, as at 7 2 ,guide said carriage to a vertical position and also bring it into place to dispose a pulley 74, embodied. in the carriage organization, for accurate engagement with the guide 7. Depending from the center of the inner side of the carriage is an arm 7 5, having its lower end secured to the upper central portion of a mail receptacle or tube 76, and as a further means of attachment of this receptacle or tube to the carriage divergent connectingbars 77 are employed, which are attached at their lower ends to the upper part of the receptacle or tube near the opposite extremities of the latter and at their upper ends to the carriage. A slide 78 is movably held between guides 79, secured to the carriage at the inner portion of the latter, said slide serving as a plunger and depending vertically to near the top portion of the recep tacle or tube 76 and then deflected horizontally outward, as at 7 9, and terminating in a vertical member 80, having a stud 81 inserted therethrough and projecting inwardly therefrom and on which the pulley 74 is mounted. Secured on the angular terminal 82 of the depending arm 75, which is attached to the top portion of the mail receptacle or tube 76, is a flat spring 83 of looped construction and having a substantially ICC llO

- pelling-arni 84.

bowed form, the horizontal member 79 of the plunger extending downwardly into the upper central cavity of this spring, as clearly shown by Fig. 3, and in continual contact with theupper part of said spring. The spring 83 always tends to force the plunger 78 and the pulley 74 carried thereby in an upward direction, the pulley 74 also providing a third track-wheel, which is disposed below the track-wheels 73 and in vertical alinement with the center of the, carriage. Instead of this spring 83 any other suitable form of spring may be used in connection with the plunger to normally retract or hold the latter elevated. By the use of the spring 83 the lower track-wheel 7 4 is caused to closely engage the lower guide-rail 8 and also causes the track-wheels 73 to be held in close contact with the rail 5. The spring 83 and the track-wheels 74 also come prominently into play in cooperating with the curved structures hereinbel'ore specified, the object being in all instances to insure a positive contact and engagement of the trackwheels 73 with the several rails both in the straight form of the brackets and in the brackets having the curved rails. Secured to the top portion of the carriage 72 is a pro- 7 (Shown by Fig. 2 in edge elevation.) This arm is given rigidity by projecting it inwardly over the upper portion ofthe carriage. Said propelling-arms after attachment to the axles or spindles depend a short distance below the latter and then extend upwardly, as at 86, and terminate in inwardly-projecting horizontal members 87, carrying heads 88, to which the lower portion of the operating-wire 1.9 is attached, the members 87 standing over and projecting inwardly beyond the upper free vertical ends 13 of the guards 12, cooperating with the guide-pulley 17. The position of the propelling-arms 84 as set forth is especially effective in rounding curves and operating in conjunction with the structure illustrated by Fig. 7, and particularly the guide-pulleys 51, held on the bar 47.

.The mail receptacle or tube 76 preferably has the contour of a cylinder, one end being fully closed and the other provided with a dropd.oor 89, having a grip or hook 90 for operating the same. To the lower portion of the center of the end of the receptacle or tube at which the door 89 is located a casting 91 is secured and is shaped to receive a corresponding casting 92, secured to an adjacent portion of the door, the two castings being pivotally connected, as at 93, to form a hinge. The casting 92 has an extension 94, which is adapted to bear against a part of the casting 91 to prevent the door or cover 89 from falling below a horizontal plane, as indicated by dotted lines in Fig. 3. To the center of the inner side of the door or cover 89 one end of a coil-spring 95 is secured, the opposite end of said spring being attached to the receptacle or tube and located within the latter. The spring 95 operates to close and maintain the door or cover in closed position, and when the door or cover is open such movement thereof is against the resistance of the spring. The door or cover 89 fits snugly in the end of the receptacle or tube 76, and as the spring is located interiorly with respect to said receptacle it will not as rapidly deteriorate as it would if fully exposed to the atmosphere. Furthermore, the spring 95 by its position does not in the least detract from the efliciency of the receptacle or tube 76 as a holding means and is strong enough to maintain the door or cover 89 in closed position under all conditions during its movement or when it is desired to have the receptacle or tube tightly closed.

In Fig. 10 the guide-pulley 17 is shown in edge and side elevation-on an enlarged scale to clearly illustrate the advantages of the guards 20, said guards having depending semicircular members 96, fitting closely over the opposite flanges of the pulley 17 and terminating slightly below or in alinement with about the horizontal diameter of the said pulley to avoid or obstruct the least tendency of the lower portion of the operating-wire passing between the opposite portions of the pulley and the side members of the support therefor.

From the foregoing the operation of the apparatus will be readily understood. If it is desired to convey mail-matter to a roadway or route traveled by a rural carrier, such matter is placed in the receptacle or tube 76 and the wire 19 is operated to cause the conveyer to move over the track-wire 6 in the direction desired, and after the receptacle has reached its destination or the point of delivery of the mail-matter the actuation of the wire 19 is ceased. The rural-delivery mail-carrier removes the mail from the receptacle or tube 76 and deposits such other mail-matter which he may have therein for the person or persons controlling the apparatus. At any time desired after the mail is placed by the carrier in the receptacle or tube the apparatus may be operated in a reverse direction to cause the conveyer to travel backwardly to a residence of the controlling person or persons. It is obvious that it would require but simple exercise of good mechanical judgment to arrange the operating and track wires on both sides of the series of posts and provide for the use of two conveyers, the same brackets and curved de vices being used, and under such conditions while one conveyer is located at the point of receipt of mail-matter the other might be positioned at the point of delivery of such matter.

It will also be understood that changes may be adopted in the dimensions and pro- 2. A mail-delivery device, consisting of a I track-wire, supports for the latter, an endless operating-wire having parts thereof above and below the track-wire, means on the supports for engaging and directing the endless operating-wire, and a conveyer movably arranged on the track-wire and having a depending mail-receptacle.
