JAMES H. TUDOR, OF LEXINGTON, KENTUCKY.

MAIL-BAG GATCHER.

Specification of Letters Patent.

Patented June 23, 1908.

Application filed March 30, 1908. Serial No. 424,070.

To all whom it may concern:

Be it known that I, JAMEs H. TUDOR, a citizen of the United States, residing at Lexington, in the county of Fayette and State of Kentucky, have invented certain new and useful Improvements in Mail-Bag Catchers, of which the following is a specification.

My invention relates to an improvement in mail bag catchers, and the device consists in having the crane attached to the car and to a post or platform along side the track, both cranes having features in common for catching and delivering the mail pouch.

The object is to provide a simple and efiicient means for catching and depositing a mail pouch or pouches whereby the sack can be drawn into the car and to the platform.

The invention consists still further in certain novel features of construction and combinations of parts which will be hereinafter described and pointed out in the claims.

In the accompanying drawings :Figure 1 is a plan view showing the frame of the car in horizontal section, Fig. 2 is a view in side elevation. Fig. 3 is a transverse section through the car door and showing the post in the rear, Fig. 4 is a view in side elevation showing the crane in its elevated position and attached to the post, Fig. 5 is a top plan view showing the arm for holding one end of the sack supported on the posts. Fig. 6 is a view of the catcher head partly broken away to show the means for holding the catcher arm when in closed position, and Fig. 7 is a detail. Fig. 8 is a view of one of the clips for holding the sacks, and Fig. 9 is a view of the clips on the arm which is supported on the posts.

A, represents the crane which is preferably U shaped and is made of tubing or solid metal, having a boiler plate 1 secured thereto by rivets 2, 2, which areprovided with partially rounded ends 3, 3, which act as bufl'ers and prevent any injury to the body of the crane, or the crane may be made of steel casting with raised edges. The ends 4, 4 of the crane extend through

boxes

4, 4 on the side of the car door in which they are capable of turning axially and sliding endwise. Springs 5, 5 encircle the ends of the crane and are held in the tubing 6 by nuts 7, 7.

A catcher head 8 similarly constructed to the crane A is connected to the crane A, and is capable of being reversed so that the catcher arm can be used in any direction in Which the car may be traveling. -A bar 9 is connected to the catcher head 8 and is held on the crane A by a clamp 10. The end of the bar is preferably screw-threaded as at 11, and a clutch nut 12 is laced on the screw-threaded end which 110 ds the bar in the position desired. A hand Wheel 13 is placed on the screw end of the bar whereby the bar is operated. At the forward end of the crane a clutch 14 engages the bar for holding it in either of its positions. On the ends of the crane A are male sockets or

projections

15, 15. On the inner end of the catcher head afemale socket 16 is formed which is adapted to receive the male socket therein for holding the head in position.

When it is desired to reverse the catcher head when, the train is traveling in a different direction from whichthe crane is set, the wheel 13 is turned, causing the head 8 to be moved outwardly releasing the clutch 14 from the brackets 14 14, and at the same time releasing the engagement of the

sockets

15 and 16 of the head and crane, and permitting the head to be reversed so that the socket 16 will engage with the male socket 15 on the crane Awhen the catcher head is drawn in toward the crane A so that the engagement will be made between the

socket

15 and 16 when the clutch will be received in

brackets

51, 51. By this means I obtain a mechanical adjustment or mechanism for reversing the catcher head. The usual catcher arm 17 is pivoted to the end of the catcher head as at 18, and the longer arm of the catcher arm 17 is provided with a curved spring 19 which is adapted to engage a pin 20 on the catcher head to hold the arm in position when a mail bag is to be caught. When the sack or pouch has been caught on the catcher arm, the impact of the catching operation will cause the catcher arm 17 to swing inwardly whereby the short arm will lie against the head 8, and a dog 21 which is pivoted to the head will engage the end of the shorter arm and hold the same in locked position. A spring 22 is adapted to press against the dog 21 to keep it in engagement with the short arm of the catcher arm. A rod 23 is connected to the free end of the dog and extends through the head 8 and to the free end of the rod a ring 24 is connected whereby the dog can be pulled from engagement with the catcher arm when it is desired to release the sack from the catcher arm. On the catcher head, and preferably along the forward end, are spring clips 25 25. Between these

clips bolts

26, 26 extend, which are spring controlled. These bolts are adapted to hold the mail sacks, and the bolt 26 is drawn inwardly by a ring 27, which is connected to one end of the bolt, sufliciently to allow the ring on the mail sack to enter between the clips, when the bolt is released and slides through the ring to sup port the sacks, and the clips 25 are adapted to engage the end of the bolt to hold it in position and prevent the bag from slipping off the bolt.

Pivotally connected to one side of the crane A is a link 28 which is provided with a forked end 29. Pivotally connected between the forked arms or ends 29 of the link 28 is a link 30 which in turn is connected to a shorter link 31 which is connected to the top or head of the car door. The forked ends 29 of the link 28 are provided with a handle 32 which is grasped by the mail clerk when it is desired to draw the crane into the car after a catch and delivery has been made. By pulling on the handle 32 and by the pivotal connections of the different arms, the crane will be drawn inward into the car for the removal of the sacks, and when it is desired to simply place the crane in a position so that it will be out of the way of anything passing along the track, it will be held in the door-way of the car in the position indicated by dotted lines in Fig. 3.

On the link 28 is a lug or projection 33 which is adapted to engage the arm 30 to retain it between the forked portion 29 of arm 28, and

to hold the crane in position for delivering and catching sacks and to hold the crane in an approximately horizontal position when drawn into the car. Hinged to the bottom of the car is an arm 34 which is provided with spring clips 35 similar to the cli s 25 which are adapted to engage and hold t 1e lower end of the sack which is suspended from the catcher head 8. The arm 34 is pivotally connected to a lever 36 which is connected to the body of the crane whereby the arm 34 is caused to be raised and lowered by the different movements of the crane.

The post or posts for supporting the crane may be made of any approved construction, but I have connected the posts 37 to a base 38 whereby it is capable of horizontal and ver tical adjustment through a slot 39 in the lower frame-work 40, through which slots bolts 41, 41 extend into and through the post 38. When it is desired to give a vertical adj ustment wedges (not shown) may be inserted between the base and frame work. The mechanism used and connected to the post is practically identical with that described in connection with the crane on the car, and duplicate numbers have been applied for corresponding parts on the posts and crane, and it will therefore be unnecessary to describe the details of construction further as to these similar parts. Secured to the top of the post are and between the end of the forked

armsare iron loops

43, 43. A board 44 is secured to the forked arms and upon which the pivoted arm 45 is pivoted as at 46. The arm 45 is adapted to pass .through the

loops

43, 43. Connected at the outer end of the arm 45 is a plate 47 having

clips

48, 48 at each end upon which clips the mail sacks are suspended. Connected to the free end of the arm is a chain 49 which is capable of engaging a hook 50 whereby the arm can be adjusted to suit requirements, and for holding back the sack in rigid position until the catch is made. The lower end of the sack or sacks which are suspended from the clips 48 are adapted to be held by clips 25 on the catcher head 8.

It is evident that more or less slight changes might be made in the form and arrangement of the several parts described without departing from the spirit and scope of my invention, and hence I do not wish to limit myself to the exact construction herein set forth, but:

Having fully described my invention, what I claim as new and desire to secure by Letters Patent, is
