MAIL-BAG CATCHER AND DELIVERER.

SPECIFICATION forming part of Letters Patent No. 686,933, dated November 19, 1901.

Application fil d January 11, 1901. Serial No. 42,899. (No model.)

To all whom it may concern:

Be it known that I, BLANCHARD CHAMBER- LAIN, a citizen of the United States, residing at Bellefontaine, in the county of Logan and State of Ohio, have invented certain new and useful Improvements in Mail Catchers and Deliverers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable oth ers skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in mail catchers and deliverers; and it consists in the construction and combinations of parts as hereinafter described and claimed.

In the accompanying drawings, Figure 1 represents a side view of my improved device.

Fig. 2 is a top view of the same. Fig. 3 is a side View of the same with the hook broken away, showing the catcher in the position it assumes after a mail bag or pouch has been caught or delivered. Fig. 4 is a side view of the sling. Fig. 5 is a cross-section of a part of said sling, and Fig. 6 is an end view of part of said sling.

a represents the usual supporting-post, which is placed at the side of the railwaytrack. This post is shown square; but it is preferably provided with a smaller cylindrical portion near its top. Just below this cylindrical portion is mounted the stationary support I), which is usually made of iron and in two halves, united together around the post a by bolts or pins 6. The lower part of the support I) is rectangular and the upper part cylindrical for the reception of the revoluble annular iron holder 0 of the catcher-arm d. This holder is usually made in two halves, which are united together by pins or bolts f and encircles the cylindrical part of the support I). The holder 0 revolves freely around the cylindrical part of the support b. Each half of the holder 2) isprovided with an extension g, between which the catcher-arm d is free to move up and down, being pivoted therebetween on the bolt h. Above the holder 0 the support b is enlarged, each half of said support terminating in a large flat cam-plate t, having a cam-surfacej and a vertical rib is.

This plate 7 keeps the holder 0 always horizontal no matter how far said holder may be rotatedaboutthesupportb. Each of theribs has a projecting portion Z.

The catcher-arm d is preferably a hollow iron tube with its inner endthat is, the end next the postbeveled off, as shown at m. This beveled end is closed bya wooden plug, beveled off to correspond to the shape of the inner end of the arm d. This plug is soaked in hot oil and then driven into the end of the arm (1, this soaking in oil serving the double purpose of excluding water or moisture from the arm d, especially when the latter is in the position shown in Fig. 3, and of supplying a lubricant to the pin 71. The arm at has a squared portion at, "through which the pin or pivot it runs, enabling the extensions g to properly guide said arm as it swings up and down. A small rope or chain 0, carrying a key 1), is attached to said arm d, which is perforated for the reception of said key. The outer end of the arm d is provided with oppositely-located slots q. A cable or chain 1' runs from a hook s onthe post at around the arm d, the upper end of said chain or cable 7" being prevented from undue slipping on said arm by the chain 0, especially when the arm d is in its proper position, as shown in Fig. 1.

The catcher-hook is provided with two diverging arms a: and w, which serve to catch the sling and guide it to the pocket or corner If, in which it is securely held. This hook has a substantially cylindrical portion c, which is adapted to be slipped into the outer end of the catcher-arm d. of the hook is provided with oppositely-located lugs tb, (formed by driving a pin through the part '0 and Welding it there,) which are adapted to fit into the slots q, rendering it possible to swing the hook over, so that it will face the opposite Way by slightly withdrawing the hook, turning it over, and pushing it back. The portion 1; is also perforated for the reception of the pin 19, which pin, together This cylindrical portion with the lugs to, hold the hook and catcherr when struck by the sling of the mail-pouch, after which the key is forced back into its normal position by the spring.

The sling, which forms an important part of my invention, is shown in Figs. 4, 5, and 6. The upper part of the sling is a knob 1, preferably of wood, approximately hemispherical in shape and provided witha groove in which is located a loop of a doubled rope 2, the other loop passing through the eye 3 of the clamp. Metal tubes 4 and 5 encircle the parts of this rope near the knob or ball 1 and the eye 3, and a longer flattened metal or leather tube 6 extends nearly the whole distance between said tubes, and the two strands of the rope are secured in the tube 6, bolts 7, provided with washers 8, serving to firmly secure said rope and tube together.

The clamp consists of three members 9, 10, and 11, the latter two of which are pivoted on the member 9 by means of the pivot- pins 12 and 13, which run at right angles to each other. The pivot-pin 12 passes through the central rib 14 and the shorter side rib 15. The member 10, therefore, can swing freely through an arc of ninety degrees in one direction, as shown in Fig. 6, but is prevented from swinging beyond the perpendicular position on its return by the casing 16 of the member 9. The lower part of themember 10 is curved in two directions, as shown in Figs. 5 and 6, and is provided with teeth 17 to enable it to firmly grip the rope, as shown in dotted lines in Fig. 4. The upper face 18 of the member 11 is inclined slightly from the horizontal, as shown in Fig. 6. This member 11 has a depression 19 in its rear, into which fits the point of a thumb-piece 20, supported on a pivot-pin 21 and normally held by a spring 22 in engagement with a depression 19 on the member 11. The thumb-piece 20 when in engagement with member 11 holds it normally in a substantially horizontal position, as shown in Figs. 4and 5, in which position the two members 10 and 11 are designed to bite or grip a rope 23, (see Fig. 4,) which rope is designed to be passed around a mail-pouch and is of sufficient length to encircle any of the mailpouches in use. When it is desired to release the pouch, the thumb-piece 20 is pressed and the member 11 drops,thus setting free the rope 23 and the mail-pouch inclosed thereby. The pivot-pin 13 is extended beyond the sides of the member 11 and on this pin is carried a swinging link 24 of the peculiar shape shown in Fig. 6-that is to say, the lower side of the link slopes downward and terminates in a depression 25. In this depression 25 is pivoted an ordinary link 26, which engages a loop 27 in the rope 23. The reason for the peculiar shape of the link 24 is that it is desirable to have the link 26 always occupy one position relatively to the clamp, and this is accomplished by the peculiar shape of the link already described.

The operation of my device is as follows:

In receiving a mail-pouch from a train the rope 23 is doubled around the pouch and the end of said rope is drawn up between the members 10 and 11. Any-pull upon the rope after it has once been adjusted between these two members simply tightens it on account of the teeth and the peculiar shape and arrangement already described. The mail -pouch and sling are then hung up upon a hook, the knob or ball 1 serving to hold the whole in their proper positions relatively to the catching device. The sling carrying the mailpouch hangs down vertically from the delivery-hook on the car and is so arranged that the ball or knob 1 is some little distance above the arms 10 and a: of the catcher-hook. As the train moves along the diverging arms of the catcher-hook come upon either side of the sling, preferably about the metal or leather part 6 thereof. This part strikes the key y, which yields and permits the sling to pass it, immediately springing back, however, into position after the sling has passed it. The distance between the rear part of the arms cow, which, as shown in the drawings, are for some distance nearly parallel with each other, is great enough to allow the free passage of the part 6, but not to permit the passage of the ball or knob 1. Consequently when the part 6 strikes the rear part of the catcher-hook the sling is thus disengaged from the delivery-hook and falls, the knob 1, however, preventing it from falling through the catcher-hook. The shock of the sling striking the catcher-hook causes said hook and the catcher-arm which carries it and the holder 0 to rotate in a substantially horizontal plane. As soon as the end of the arm d passes beyond the projecting portion Z of the rib is the weight of the arm and pouch would naturally cause the arm and hook to fall into the position shown in Fig. 3. To insure positive action, however, and to make it inevitable that the arm (1 must fall I, have provided the camplate 2' with the cam-surface j. This camsurface, catching under the inclined beveled portion m of the catcher-arm d, throws this end up, causing the catcher-arm to fall. Moreover, the chain or cable 1' as the arm revolves around the post a prevents the arm 01, with the catcherhook and mail -pouch carried thereby,from swinging around too far. When, therefore, the catcher-hook is struck by the sling it is swung to one side and simultaneously dropped into a substantially vertical position. This of course draws it away from IIO the train, thus preventing accidents either to the pouch or to the train. My improvement may also be used for delivering a pouch to a train by turning the hook in the opposite direction and allowing the sling to be supported by said hook, the ball being supported by the arms as 10 thereof. Of course the catching device, which is located on the moving train, must be so adjusted as to strike the sling below the knob or ball 1.

It is obvious that many changes might be made without departing from the spirit of my invention, and I wish it to be expressly understood that I do not limit myself to the exact details shown and described.
