MAIL-DELIVERING- DEVICE.

Patented Oct. e, 1908.

Application filed January 16, 1908. Serial No. 411,175.

To all whom it may concern:

Be it known that I, GEORGE. MALDElW.

and to provide a simple, inexpensive and ef-' ficient device of great strength and durability, adapted to be readily applied to a mail car, and capableof swinging into and out ofthe same to enable'a mail bag to be conveniently applied to it and to support the mail bag beyond the car in position to be caught by a mail bag catcher.

A further object of the invention is to provide a double mail bag catcher, adapted to take a mail bag from a train approaching it in either direction, and capable of firmly gripping a mailbag and of enabling the saine to be conveniently removed from it.

With these and other objects in view, the

invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resortedto without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings :-Figure 1 is a perspec tive view of a mail bag delivering device, constructed in accordance with this invention, a mail bag being shown in dotted lines. Fig. 2 is a vertical sectional view of the mail bag catcher. Fig. 3 is a horizontal sectional view of the same. Fig. 4 is a detail view of the upper portion of the crane. Fig. 5 is a detailperspective viewof the catch for lock-.

ing the crane in an extended position.

Like numerals ofreference designate corresponding parts in all the figures of the drawings.

The mail bag 1, illustrated in dotted lines in Fig. 1 of the drawings, is supported in an extended position beyond the side of a mail car 2 by means of a crane, comprising upper 4 and a vertically disposed hinged bar 5, provided withupper and of which swing upwardly modate the crane to mail bags of different the hinged bar 5 is extended lower perforated ears 6 passes a pintle rod 8. The pintle rod 8 is mounted in eyes 9 of upper and lowerbrackets 10, secured to the car 2 int-he door-way thereof in position to permit the crane to swing This will enable a mail bag to be applied to the crane while the latter is within the car andwithout danger to the mail clerks- The pintle rod, which is provided at its upper end with a suitable head, has its lower end threaded for the reception of a nut for retaining,it in the eyes of the brackets.

The arms 3 and 4 are provided at their outer ends with pivoted mail bag engaging devices 11 and 12, having horizontal ortions for engaging the loops 13' at the on s of the mail bag. The mail bag engaging deand 7 through which vices are substantially L-shaped, one arm or portion of each forming a pivot to permit the other arm to be turned in the opposite-direction from which the train is traveling, so that the mail bag will readily slip from the crane when it is engaged by the mail bag catcher hereinafter described. The upper mail bag engaging device pierces the upper arm and is retained ma perforation thereof by means of upper and lower nuts 14. The lower arm 4 is provided at its outer end with a block or head 15, which is provided with a perforation for the reception of the pivoted portion of the lower bag engaging device, and the latter is retained in the perforation of the block or head 15 by means of upper and lower nuts The upper arm 3 is pivoted at its inner end between cars 17 of the crane by means of a horizontal bolt 18, and it is adapted to and downwardly to accomlengths, and a coiled spring 19 is connected with the arm for stretching the mail bags, wherebythey are securely held by the engaging devices 11 and 12. The upper end of above the upper arm-and is pierced by an eye bolt 20 to which one end of the spring is connected by a link 21. The spring, which is arranged at an inclination, extends outwardly and downwardly from the ring 21 to the upper arm and is connected with the same at a point intermediate of the ends thereof by means ofa ring 22 and an eye bolt 23, which ierces the upper arm. The upward swing of t e arm3 is limited by means of a lug-24, formed integral with the hinged bar and projecting therefrom at a point above the ears 17 as. clearly illustrated horlzontally into and. out of the car.

in Fig. 1 of the drawings. The hinged bar is also equipped with a horizontally projecting lug 25, formed integral with the hinged bar and located at a point between the upper and lower arms 3 and 4 and arranged to be engaged by a catch 26. The catch 26 is pivoted at one end to the exterior of the car by means of a bolt 27, and it is provided with depending lugs or projections, forming an intervening recess 28 at its lower edge to reeeive the lug 25 of the hinged bar 5. The catch 26 is adapted to rigidly maintain the crane in its extended position, so that the crane will operate when the car is traveling in either direction.

The mail bag catcher comprises fixed and movable members 29 and 30, disposed horizontally and curved longitudinally to present inner convex faces, which form diverging mail bag engaging jaws at each end of the catcher, whereby the latter is adapted to receive a mail bag from a train approaching it in either direction. The members 29 and 30 are preferably constructed of sheet metal, having their side faces arranged in vertical lanes and reinforced by upper and lower ongitudinal metallic bars 3]. and supported by braces 32 and 33. The braces 32 extend from the outer portions of the fixed member 29 to vertical standards 34 to which the mail bag catcher is secured and which forms a support for the same, but any other suitable sup- 4 port may be provided at a station for the mail bag catcher.

The fixed member 29 is supported by rigid brackets 35, composed of upper and lower arms and a vertical connecting portion. The vertical portion is secured to the standards 34 at the upper ends thereof, and the horizontal portions have their outer ends bent at an angle to form attaching ortions, which are secured to the fixed member 29 by fastening devices that pierce the longitudinal reinforcing bars 31.

The member 30, which is movable inwardly and outwardly toward and from the fixed member 20, is supported by a pair of brackets 36, composed of upper and lower vertical portions and an intermediate horizontally disposed connecting portion. The upper vertical portions are secured to the member 30 by fastening devices, which pierce the upper and lower longitudinal reinforcing bars, and the lower vertical portions are pivoted at their lower ends to the standards by fastening devices 37, piercing the brackets and also horizontally disposed L-shaped bars 38, which are secured to the standard 34. The L-shaped pieces, which are constructed of metal, provide supports for the pivots of the bracket.

The movable member 30 is maintained at the limit of its inward movement by coiled springs 39, secured to the vertical portions of the pivoted brackets and to a frame 40,

disposed horizontally and mounted on the standards 34. The frame is substantially U-shaped being composed. of two sides and a connecting portion, which is provided with perforations into which the outer ends of the springs are hooked. The lower vertical portions of the pivotal brackets are provided with a plurality of perforations 4]., receiving the inner ends of the coiled springs and per mitting the same to be adjusted to increase the tension of the springs should it be neces sary to tighten the same.

Nhen. the mail bag moving in the direction of the arrow in Fig. 1 of the drawings engages the mail catcher, it is received between t h c ad jacent diverging end portions or jaws of the members 29 and 30. The force with which the mail bag comes in contact with the mail bag catcher is sufficient to cause the former to spread the jaws of the latter, whereby the mail bag will be securely clamped between the members 29 and 30. This will prevent the mail bag from falling from the mail bag catcher and there will be no liability of the mail bag being injured by the wheels of the train.

The mail bag is released by an operating device comprising a pair of cams 42, mount ed on a horizontal shaft 43 and arranged to enthe lower vertical portions of the pivot ed brackets. The shaft 43 is jouriniled in suit able bearings 44 of the staiulards 34 and is provided at one end with. an operating arm 45. The cams, which consist of disks llattened at one side, are eccentric/ally mounted on the shaft and the flattened sides lit a gainst the pivoted brackets, as illustrated in Fig. .I of the drawings when the movable member 30 is at the limit of its inward movement. i/V hen the shaft is partially rotated, the cams engage the pivoted brackets and swing the same outwardly thereby carrying the movable member 30 away from the fixed member 29 and enabling the mail bag to be readily removed from the device.
