AUTOMATIC MAIL-DELIVERY APPARATUS.
SPECIFICATION forming part of Letters Patent No. 751,464, dated February 9, 1904.
' Application filed November 19, 1902. Serial No. 132,036. (No model.)
To all whom, it may concern: I
Be it known that I, IsAAo F. COLE, a citizen of the United States, residing at Williamsfield, in the county of Knox and State of Illinois, have invented certain new and useful Improvements in Automatic Mail-Delivery Apparatus; and I do hereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to an apparatus for automatically delivering mail.
The object of the invention is to provide an apparatus consisting of a car and an overhead track for the same which is arranged to carry mail over rural routes and automatically deliver the mails to their respective destinations, all of which will be described in the following specification.
Figure 1 is a view showing a building from which tracks extend supported by poles and showing a mail-car suspended on such tracks. Fig. 2 is a perspective view of the mail-car,
showing the track from which it is suspended.
and wires above which convey power to -a m0- tor situated within the car, but not shown, such figure also showing a mail-box with which the said car contacts in its onward movement.
Fig. 3 is a side elevation in section of the car, showmg 1ts 1nter10r arrangement. Flg. 41s a plan view of the same 1n section. Flg.
5 is a perspective view of portions of the interior mechanism of the car. 7
In Fig. 1 is illustrated a building which may be the post-oflice from which the mail is to'be delivered. A track A extends from the building along poles B set at intervals to support the same, and a car 0 is suspended from said track by means of hangers D and wheels E.
said wheels being attached to the side of the 5 car in any good manner. The lower vertical flange of the track is provided with teeth G, with which engages a pinion-gear H, driven from the motor (not shown) from a gear I.
It will be seen that power applied to drive the 5 5 gears will propel the car by means of the said teeth G. However, it is not my purpose to confine myself to this particular propelling means, as I may drive directly by means of the wheels E on the track A. Other means 6Q of propulsion may of course be used, if desired. 1
Attention is now directed to the interior arrangement of the mail-car;;and the same may be understood from the following: Two s I shafts J and K are suitably journaled inthe sides of the car and eachcarries two sprocketwheels J and K, respectively. These pairs of wheels are located opposite each other near each end of their shafts-and carry sprocket- 7o chains L and M. The said chains are provided with plates N, which are secured thereto in rigid manner, said plates being held at right angles to the length of the chain, as shown, and being attached to a separate link in any good manner are permitted to pass around the sprocket-wheels in the onward movement of the chains. Adjacent to said plates N are other plates 0, which are held by means of pins P, passing therethrough, which are held at one end in rigid manner in the plates N. Such pins. pass through the plates 0, and the latter are adapted to slide upon them and held in place by means of springs Q. Between the plates N and O the articles to be mailed are held. Suflicient space is left between the chains in which to insert the longest articles usually carried in the mails, and the postmaster merely separates the plates. against the pressure of the springs and in- 9 serts the mail to be delivered, and on releasing the spring-held plate 0 the mail is firmly held and cannot be dropped until liberated by the proper means, which will be described presently. In placing the mail within this car the various articles are placed in the order in which they are to be delivered-that is to say, in rural delivery perhaps fifty or one hundred lots of mail are to be deliveredin doing which the mail-carriers usually have the various deliveries arranged in the order in which they successively arrive at their various destinations. Therefore the postmaster will place each lot of mail within the inclosing plates in the same order until all the mail to go out is distributed through the various compartments, and when the car is thus loaded the chains are adjusted so that the first lot to be delivered is brought just above an opening at R in the bottom of the car.
The means for delivering the mails may now be described. It consists in placing a rockshaft S in the opening R and provided at one end thereof with a pinion-gear T, with which meshes a larger gear U on a shaft V, having a bearing at V on the floor of the car out of reach of the plates N and O. At the outer end of the shaftV is an arm X, (better shown in Fig. 2,) which is controlled by a spring Y, attached at one end to the upper end of said arm and at the other to the side of the car. On the shaft S are two jointed curved arms Z Z, one at each end of the said shaft and each in position to engage a projecting car on each end of each of the plates 0. The arms Z are so located that the movement of the plates N and O, with the chains, is not interfered with, and when in their normal positions the said arms lie Withimthe opening R, as shown in Fig. 3. The arm X at the outside of the body is adapted to engage a projecting arm 2 on the side of the mail-box, as shown in Fig. 2. Said box (designated by the letter a) has a curved cover 3 designed to slide within suitable guides, which are not shown, because they form no part of my invention, and a lug 4 on said cover is met by the car as the latter approaches the box, and the box is at once opened by sliding the cover back, and said cover is held open as long as the car is above it, since the lug 4: is continually held by the sliding car. Now during this time the arm X meets the arm 2 on the box and is moved against the pull of the spring to turn the wheel U, whose movement imparts a movement to the gear T to raise the arms Z Z to contact with the said projections of the plate 0. As this movement takes place the plate 0, which is just above the opening R, is moved against the tension of the springs holding it and releases the mail held between it and the plate N and allows it to drop into the box a beneath. It now becomes necessary to shift the entire lot of mail to a position whichwill bring the next mail-compartment above the opening R, so that its contents may be dropped into the next box in the manner just described. To do this, I have provided on the shaft J a ratchet-wheel 5, which is secured rigidly thereto, and with such wheel engages a pawl 6, which is loose on the shaft, so as to swing thereon, and to it is pivoted one end of an arm, whose lower end is in turn loosely attached to a bell-crank or lever 8, pivoted at 9 to a bracket 10 on the side of the car. The other extremity of such bell-crank is in engagement with an arm 11, secured to a vertical shaft 12. journaled to the outside of the car, as shown at 13. The lower end of said shaft carries a horizontal arm 14 for engaging the vertical portion of the arm 2 of the.
mail-box a. It will be seen that a spring 15 normally holds the arm 14 at an angle to the side of the car, as shown in Fig. 5, and it is intended that the said arm 2 will contact with such arm 14 at a point just forward of the shaft 12, and as the car moves forward said arm 14.- will be turned with the shaft against the pull of the said spring 15, and this action will operate the bell-crank 8 to raise the pawl 6 and turn the ratchet-wheel and the sprockets and their chains a suflicient distance to bring the desired mail-compartment above the opening R. Before this movement takes place the spring Y has placed the arms Z out of the way of the oncoming plates. However, if for any reason said arms are met before they reach their normal positions or position of rest I have provided that they may have a hinged joint at Z, so that they may freely double over after the manner of a jack-knife when the plates meet them, and after such plates pass a spring Z on each returns the portions to their proper positions. On the shaft K, I provide a friction-drum K around which is placed a band K whose ends are secured to a block K in the top of the car. This device keeps an even friction which prevents the sprockets revolving except when turned positively by the pawl mechanism described. By the means described it will be seen that as each mail-box is met and passed said box is opened, the mail is deposited therein, and the next compartment to be delivered of its contents is brought into position above the opening in the bottom of the car for the next delivery. A spring is employed on the mailbox afor closing the cover 3 after the car has passed over.
In erecting the system the wires and tracks are carried high above the street, so as to interfere with nothing, and when reaching the country the tracks are then lowered and carry the car over the mail-boxes.
I may use any other kind of power for operating the cars than that already mentioned and may change the various means of dropping the mail into the boxes and for shifting the mail-compartments for bringing the desired one above the delivery-opening of the car and, in fact, may change the entire arrangement without departing from the spirit and intent of my invention.
