MAIL-BAG RECEIVING AND DELIVERING APPARATUS.

Specification of Letters Patent.

Patented Dec. s, 1908.

Application filed July 20, 1908. Serial No. 444,480.

To all whom it may concern:

Be it known that I, GUsTAvEs LINDAHL, citizen of the United States, residing at New Carlisle, in the county of St. Joseph and State of Indiana, have invented certain new and useful Improvements in Mail-Bag Receiving and Delivering Apparatus, of which the following is a specification.

This invention relates to certain new and useful improvements in mail bag receiving and delivering apparatus.

The invention has for its object the production of an apparatus of this character by means of which mail sacks may be received by a moving car and simultaneously effect a safe delivery of the local mail sack for the station which said car is passing.

A further object is to provide an improved form of catch constructed to automatically and securely engage a mail sack supported from a crane adjacent to the railway track.

A further object is to provide an improved catch automatically operated to deliver the local sack into a suitable receptacle adjacent said track.

The invention will be hereinafter fully set forth and particularly pointed out in the claims.

In the accompanying drawings :Figure 1 is a perspective view of the catcher and deliverer. Fig. 2 is a perspective view illustrating my improved mail receiving and delivery apparatus. Fig. 3 is a plan view of the same. Fig. 4 is a sectional view on the line 3-3 of Fig. 3.

Like characters of reference designate corresponding parts.

Referring to the drawings, 10 designates a T-shaped operating arm pivotally mounted in the door-opening of a car and free to be swung in a horizontal plane, said arm being provided with an operating handle 11. The extension 12 of said arm 10 is provided with an integral rigid finger 13, and adjacent thereto is pivotally mounted a gripping finger 14 which is held normally in contact with said rigid finger by means of a spring 15. A setting link 16 is ivotally connected to finger 14, and provi ed with an angular uide 17 through which is projected a pivoted latch 18 carried by the angular projection of an L- shaped operating arm 19 ,which is also pivotally connected to said setting links as indi cated at 20. The shank of the operating arm 19 isprovided with a slot 21 through serving as a guide for the latter. A spring 22 acting against operating arm 19 serves to retain the latch 18 normally in engagement with a catch 23, carried by finger 13. The extension 12 terminates in a vertical arm 24, provided with a curved arm 27 and at'its lower end with a channel or guide 25. The discharging lever 26, is pivotally supported by bar 24, with its lower end moving in guide 25, and provided with a rearward extension 28, projected through a suitable opening in.

arm 27. A spring 29 carried by a curved horn 30 serves to hold the lever 26 with extension 28 normally in engagement with arm 27.

Adjacent the track at the point where it is desired to deliver mail, is located a crane 31, having an overhanging arm 32 and a basketlike receptacle 33.

In practice the mail sack to be taken up by the train is suspended from arm 32 by any suitable clip-device 34. The operator in the car draws back gripping finger 14 until latch 18 is caused to engage catch 23, thus setting the said gripping fingerin operative position. The sack to be delivered is provided with a suitable ring through which extension 27 is.

passed, the spring 29 serving to prevent acciental disengagement thereof. As the train approaches the crane 31, the operating arm 19 strikes the mail sack, whereupon the impact will disengage latch 18 from catch 23, and finger 14, under the influence of spring 15, coacting with finger 13, will grip the sack and securely retain the same until the apparatus is drawn into the car. At the same time as the foregoing, the upper end of discharging lever 26 strikes arm 32, disengaging the extension 27 from the mail sack and depositing thelatter into the receptacle 33.

From the foregoing it will be seen that I have produced a simple and inexpensive apparatus for receiving and delivering mail sacks, which apparatus is provided with improved devices for securely holding the mail sacks and preventing accidental isengagement thereof. It will also be observed that my improved mail bag receivin and delivering apparatus being ccnstructe of few parts,

is not liable to readily get out of order or be-' come deranged.

Claims.

1. An apparatus of the character described, comprising an operatingarm provided with an integral finger, a gripping finger pivotally which the gripping finger 14 is projected and I connected to said arm, a setting link connected to said gripping finger, and provided with a latch, a catch carried by said integral finger and coacting with said latch, and an operating arm for disengaging said latch when struck by a mail sack.

2. An apparatus of the character described, comprising an operating arm provided with an integral finger, a gripping finger pivotally cgnnectei to said arl 'irlrli, a setting link connecte to sai ri pin er, a tri in arm iv otally con iie ted to siid llIIk SHd PI'OVi ElGd with a latch, and a catch cooperatlng with said latch.

3. An apparatus of the character described comprising an operating arm provided with an integral finger, a gripping finger pivotally connected to said arm, a setting link connected to said gripping finger, an L-shaped operating arm pivotally connected with said link, a latch pivoted to said arm, and a catch cooperating with said latch.

4. An apparatus of the character described comprising an operating arm provided with an integral finger, a gripping'finger pivotal ly connected to said ar-m, a-settmg link c'o nn'ected to said gripping finger, an operating arm for disengaging said l-inlk, said arm being provided with a guide slot through which one end of said gripping finger is projected.

5-. An apparatus of the character described comprising an operating arm, and a sprite pressed discharge lever pivotally sup orte thereby and provided with a rearwar ringengaging extension.

6. An apparatus of thecharacter described comprising an operating arm, a spring pressed discharge lever pivotally sup orted thereby and provided with a rearwarc ring engaging extension, and means for guiding the lower end of said discharge lever.

7. An apparatus of the character described comprising an operating arm, and a spring pressed discharge lever pivotally sup orte thereby and provided with a rearwar ringengaging extension, said arm being provided with a channel or guide for the lower end of said discharge lever.

8. An apparatus of the character described comprising an operating arm having an upright portion provided with a guide channel and a guide finger, and a spring-pressed discharge lever supported by said upright portion and having its lower end in engagement with said guide channel, said lever being also provided with a rearward extension normally engaging said guide finger.

9. The combination with a mail bag crane having an overhanging arm, and a receptacle below said arm, of a receiving and delivery device comprising an arm provided with gripping fingers adapted to engage a mail sack supported from said overhanging arm, and a discharge lever adapted to engage said over hanging arm to effect the deposit of a mail sack into said receptacle.

In testimony whereof I affix my signature, in presence-of two witnesses.
