- Deliverers, of which the following is a specification.

The mechanism of this invention is of the type particularly adapted for use in connection with the delivery and collection of mails between small stations and passing trains.

suspension of the mail bags to be delivered and collected, and embodies certain hereinafter pointed out improvements over prior devices of this nature.

Among the objects of this invention are a simplified construction without sacrificing any of the features found convenient and necessary for the use and operation of this class of devices; a durable and positively acting structure which may be economically installed, and a structure wherein the working parts thereof are protected as far as possible and without hindering the free opera tion of the same.

Other objects and advantages of this invention will be pointed out in the following detail description of the present embodiment thereof, the same being illustrated in the accompanying drawings in which- Figure 1 is a side elevation of the apparatus as applied to a car and a crane, the apparatus being shown in position for transferring the mail bags between the train and the crane. Fig. 2 is a top plan view of the car fork in set up position to receive a mail bag, a fragmentary view of the car being shown in section. Fig. 3 is a side elevation of a portion of a car showing the car fork in the raised position of Fig. 2 and show ing the mail bag support extended, the dotted. lines disclosing the car fork dropped down in inoperative position. Fig. 1 is a top plan view of the crane in position to receive a mail bag. Fig. 5 is a side elevation of the same partly in section, the dotted lines showing the crane in dropped position when out of use.

Referring to these figures wherein like parts are designated by similar characters of This mechanism is of the well. known forked type combined with chain reference throughout the several views, and referrlng particularly to Figs. 1, 2 and 3, 1O designates the car provided at the opposite sides of the doorway thereof with brackets 11. The car fork of this invention comprises a swinging frame having a rod 12 mounted near its opposite end for rotation in the opposite brackets 11, the rod 12 preferably having a longitudinal sliding movement in the brackets 11 for a purpose hereinafter brought out. The rod 12 carries an outer fork arm 13 projecting outwardly and forwardly from the rod 12 at a point near its rear end, the arm 13 being reinforced by a bar 14 extending from the rod 12 directly outward and joining the arm 13 at a point forwardly of its juncture with the rod 12. This structure is disclosed to advantage in Fig. 2 of the drawings, and wherein it will be seen that the arm 13 is offset inwardly at its intermediate portion to provide a retaining lip 15 for engagement with the mail bag chain as hereinafter pointed out. The rod 12 is further provided intermediate its ends with an arm 16- projecting from the rod diametrically opposite to the fork arm 13. Offset laterally from one side of the arm 16 is a handle 17 adapted to be grasped by the operator to swing the car fork upon the brackets 11. A spring latch 18 carried by the car 10, preferably depends from the top of the car and registers at its lower end with the inner extremity of the arm 16.. As may best be seen in Fig. 8, the latch 18 is apertured at its lower end as at 19 to receive the extremity of the arm 16 for the purpose of holding the arm from turning after the car fork has been adjusted into horizontal position as shown in Figs. 1, 2 and 3. The frame of the car fork is provided with an inner or second arm 20 hinged at its forward end upon a finger 21 extend ing forwardly from the base of the arm 16 and rod 12. The second fork arm 20 is curved in such a manner that its bulged part contacts with the lip 15 when the fork arm 20 is swung out against the outer fork arm 13. The inner arm 20 is provided upon its free end. with a guide22 preferably forked, and engaging about the brace 14, so as to steady the arm 20 in its swinging movement. The guide 22 is curved inwardly from the arm 13 m as to provide between the guide 22 and the arm 13 a loop for the reception of the mail bag chain. A yoke 23 straddles the rod 12 and arm 16, and extends in the longitudinal direction of the arm. The yoke 23 is hinged at its outer end upon the intermediate portion of the inner fork arm 20 and is secured at its inner end to a collar 24 slidable upon the arm 16. A spring 25 is secured at its inner end to the collar 2 1 and at its outer end to the rod 12 and exerts a tension upon the collar 2% and yoke 23 to yieldingly hold the fork arm 20 outwardly against the fork arm 13.

It will be noted particularly from Figs. 1 and 2. that the collar 2t is located in close proximity to the lower end of the latch 18 and that any slight movement imparted to the arm 20 to move it inwardly forces the collar 21 against the latch 18 and frees the arm 16 from the latch. Such operation allows the car fork to swing down into vertical position as shown in dotted lines in Fig. If preferred a spring 26 or other device may be placed upon the rod 12 between the rear bracket 11 and the fork arm 13 to take up jar incident to the sudden impact of the mail bag against the fork. Positioned preferably beneath the rear bracket 11 is the mail bag support used in the delivery of a mail bag to the crane. This support, as disclosed in Figs. 1 and 3, comprises parallel bars 27 with vertical pins 28 upon their inner ends for engagement in eyes 29 secured against the side of the car. The bars 27 are held in fixed relation to each other by braces 30, or other suitable means which produce a rigid supporting frame. Upon the outer end of each of the bars 27 is disposed, preferably adjustably, a clamp 31 extending outwardly and rearwzrdly from the bar 27. These clamps 31 are arranged preferably one above the other and are adapted to receive portions of the mail bag chain so as to hold the latter in stretched position and vertically to be caught by the crane as hereinafter set forth. Since the pins 28 of the support are mounted in the eyes 29, the support is permitted to swing upon the eyes so that the support may be drawn in against the side of the car.

The crane of this invention, which cooperates with the above described car fork, comprises a post 32 rising from theroad bed at one side of the track and carrying a pair of upwardly extending and inwardly curved bracket plates 33 at the upper end of the post. A transverse bar 34 is rigidly mounted in the ends of the bracket plates 33, the bar 34 being mounted so that it will not turn and being provided at its middle portion with a segment 35 provided with a downwardly facing shoulder 36 at its inner side. A loop frame 37 is mounted toward oneend for rotation. upon the bar 34 and carries at said end a beam 38 provided upon its extremity with counter-balancing sides 39 adapted to offset the weight of the outer end of the crane hereinbefore described. The loop frame 37 projects outwardly from the bar 31 to a considerable distance and is provided in its opposite sides with a pair of registering and longitudinally extending slots 4-0 receiving the opposite ends of a tripper rod 41.. The tripper rod 4 1 carries a pair of in 'ardly extending bars 4-2 secured at their inner ends upon a latch 13 adapted to engage beneath the shoulder 36 and hold the loop frame 37 in raised position. The latch 43 is provided with a guide pin ll projecting into the recessed inner end of the beam 38 to hold the latch from rising when released from the shoulder 30. The bars 42 each carry a spring 45 extend.- ing outwardly to the end of the frame 37 where each spring is secured to a hook 4:6 carried upon the outer end of a bar 4-7 projecting longitudinally within and beyond the frame 37. The bar 17 is secured to the frame 37 in fixed relation thereto and is adapted to swing therewith. A rail 48 extends transversely through the intermediate portion of the frame 37 and is secured at its riddle portion to the inner end of the bar 47. The rail 48 projects at either side from the frame 37 to a considerable distance and carries a fender 49. The fender -19 is shown in the present instance as comprising a pair of flatmetallic strips extending from the opposite ends of the rail 48 to the middle portion of the beam 33. A plurality of spaced apart parallel rods 50 are secured at their opposite ends in said metallic strips and the rail 18 respectively. The frame 37 is provided upon its outer end with a. double forked arm 51.. the same passing transversely through the frame 37 in parallelism with the rail 14.8 and having its opposite ends diverging outwardly from the rail -18 and extending a short distance beyond the extremities of the same. This construction is shown to advantage in Fig. 4: of the drawings. An inner fork arm 52 is pivoted to each end of the rail 48, the inner forked arms 52 extending toward the frame 37 and being curved outwardly into proximity to the ends of the outer arm 51. The inner free ends of the fork arms 52 are offset inwardly to provide spaces or loops for the re .ception of mail bag chains, and also to provide abutments for engagement with the tripper rod 41 when. the arms 52 are swung away from the arm. 51 as the mail bag chains pass between these arms. The rail 48 carries a pair of guiding straps 53 which project forwardly in parallelism with the frame 37 and pass against the upper and lower sides of the outer arm 51, the inner arm 52 and the tripper rod 41 at each side of the frame 37. The straps 53 admit of the free movement of the arms and the tri'pper rod and at the same time hold the same from displace ment. 7

Fixed upon the post 32 of the crane is an arm 54 which rises from the post and is offset outwardly toward the track. An arched lever 55 is hinged at one end adjustably upon the upper end of the arm 54:, while to the opposite end of the lever 55 is pivoted a. depending bar 56. The bar 56 is hinged at its lower end upon a bracket 57 fixed to the bar 47 carried upon the frame 37. From Fig. 5 it will be seen that when the frame 37 is swung down to the dotted line position the depending bar 56 will be drawn down thereby and will swing the arched lever 55 down into the dotted line position shown. The depending bar 56 is provided with a pair of outwardly extending supporting arms 58 hinged in spaced relation upon the bar 56,

and have their inner ends projecting beyond their pivotal connections with the bar 56. A link 59 connects the inner ends of the arms 58 insuring the movement of the arms in parallelism with. one another, A spring 60 is secured at one end to the link 59 and at its opposite end to the bar 56 and exerts a tension on the link 59 to raise the arms 58 and fold the same upwardly out of the way when it is not desired to deliver a mail bag to the train. The outer ends of the arms 58 are provided with adjustable clamps 61 for engagement with the chain of the mail bag to be delivered to the train. From Fig. 5 it will be noted that when the mail bag support of the crane is elevated into operative position the upper end of the link 59 strikes the arched lever 55 and limits the downward swinging of the arms 58 so as to support the mail bag in proper position.

From the foregoing description taken in connection with the accompanying drawings, the following described operation of the device will be readily understood. Referring to Figs. 1 and 3, when the car 10 approaches a crane and it is desired to discharge a mail bag A, the support 27 is swung out at the side of the car after the usual chain of the mail bag A has been secured upon the clamps 31. With reference to Figs. 1, 1 and 5, it will be noted that when the car 10 reaches the crane the chain of the mail bag A is in the path of the fork arm 51 of the crane and that the chain slides inwardly against the fork arm 51 and will strike the free end of the inner fork arm 52, swinging the same inwardly and effecting the gripping of the chain between the fork arms. At this time the chain is drawn out of engagement with the clamps 31 of the car bracket. Also, the inner movement of the fork arm 52 causes the latter to strike against the tripper rod 451 which moves the bars 42 inwardly and displaces the latch 43 from beneath the shoulder 86. The weight of the mail bag between the fork arms 51 and 52 now swings the frame 37 down about the stationary rod 3 1 as a pivot, into the position disclosed in dotted lines in Fig. 5. lVhen it is desired to deliver a mail bag to the car 10 from the crane, and assuming the crane to be in the position shown in Figs. 1, 4t and 5, or in elevated position, the mail bag B is suspended by its chain upon the clamps 61 so that the chain is stretched vertically by the clamps. The link 59strikes the arched lever 55 and holds the mail bag in hanging and extended position as may be seen in Fig. 1, As the car 10 approaches the crane the operator grasps the handle 17, Figs. 1, 2 and 3, and swings the car fork, into raised position as shown to advantage in Fig. 1. As soon as the car fork reaches its horizontal position the latch 18 snaps over the end of the arm 16 and locks the car fork in position. As the car 10 moves past the crane, the fork arm 13 engages between the supporting arms 58 of the crane and strikes the chain ofthe mail bag B, drawing the chain. away from the clamps 61 and between the fork arm 13 and the inner fork arm 20. As the chain passes between the fork arms 13 and 20, the fork arm 2O is swung inwardly and. pushes the yoke 23 toward the extremity of the arm 16. This movement slides the sleeve 21- over against the latch 18 and forces the latch from engagement with the arm 16. As the arm 16 is released from the latch the train fork falls with the mail bag B into the dotted line position shown in Fig. 3 of the drawings, The spring 25 immediately returns the sleeve 24-, yoke 23 and the inner fork arm 20 to their normal position. As is usual, the mail bag chains are provided with the disks or plates near their upper ends, as is shown in Fig. 1, so as to hold the chains from slipping down between the forks of the car and the crane.

As soon the mail bag B is released from the arms 58, the spring 60 draws the link 59 down from engagement wit-h the arched lever and swings the arms 58 u out of the way as is shown in dotted lines in Fig. hen the crane is released from the segment 35 and caused to swing down, as shown in Fig. 5, in dotted lines, the bar is drawn down with the crane and pulls with it the arched lever which holds the bar 55 close against the crane and out of the way when the apparatus is inoperative. Since the arched lever 55 is adjustably connected to the upper end of the arm 5a by means of the row of openings shown, the depending bar 56 may be adjusted into the desired angle and consequently move the supporting arms 58 toward or from the crane as desired.

It will be observed from Figs. 2 and Set the accompanying drawing that the car bracket 27 is provided upon its inner end with rearwardly extending shoulders 62 at the inner ends of the arms constituting the car bracket. lVhen the arms 27 are swung out into the position shown in Figs. 2 and 3 the shoulders 62 strike rebound blocks 63, formed preferably from rubber although any other suitable material may be used, secured to the side of the car 10. \Vhen the car bracket 27 is in extended position to support a mail bag A, as shown in Fig. 1, the bracket remains in such position until the train passes the crane fork. The impact of the crane fork striking the bag A and seizing the same is exerted through the bracket 27 to the shoulders 62 causing the same to press into the blocks 63, and the sudden release of the mail bag from the bracket 27 frees the latter and the rebound blocks 63 throw the bracket :27 inwardly against the car, as

into the dotted line position shown in Fig. 3

and crosses the upper arm of the car bracket 27 and prevents the same from swinging-Youtwardly into extended position. This interlocking of the bracket and the car fork is shown in dotted lines in Fig. 3.
