To all whom it may concern:

Be't known that I, Tuoon F. BnoWN, a

- citizen of the United States of America, and

resident of Newark, in the county of Licking and State of- Ohio,--have invented certam new and useful Improvements in Po'uch- Transferring Devices, of which the following is a specification.

This invention relates to mail or package transferring devices usually referred to inthe art as mail cranes, although applicants such as an aeroplane or dirigible, the said suspendmgmeans being equipped with a invention is capable of use in connection with the deposit and removal of pouches, bags or the like. i In the further description of the apparatus, it will be referred to as innse in connection with mail pouches or bags, hut-it is to beunderstood that the terms shall be regarded as including other objects or containers that may be released or gathered during the travel of an aeroequipment.

It is an object of, this invention to provide novel means forsuspending a pouch from an air transport of any appropriate type.

trip or release whereby the pouch 'is diseng'agedfrom its suspending means or car rier in order that pouches which are carried by the suspending mean may be deposited at certain stations with respect to which the transport is traveling, and it is a further object of this. invention to provide novel means whereby the said suspending device may be operative to collect pouches from stations equipped with a crane of the character indicated. I

, It is a furtherobject ofthis invention to provide a'crane having means for guiding asuspending device or collector in order that it will he directed into 0 erative relation to the pouch carrier or yo e which the said suspending device will engage ln removing' I the pouches from thecranein order thatthely may be transferred to the transport. t is a further object of this invention to so mount the crane as to permit it to turn in diderent directions in order that it may be relieved of undue strain when the pouch" carrier or yoke is dislodged from the crane; 1t is furthermore an object of this inven-- tion to produce an apparatus 'of the char,

acter indicated which-will be strong 'and durable, as well as efiiclcnt and satisfactory in use.

, With the foregoing and other objects in .view, the inventioniconsists in the details of construction, and. in the arrangement and combination ofpart to be hereinafter more fully set forth and claimed.

1 In describing the invention in detail, reference will be had to the accom anying drawings forming part of this app ication, wherein like characters denote corresponding parts in the several views, and in whic Figure 1: illustrates a view in perspective of a crane embodying the invention;

Figure 2' illustrates a sectional viewof a suspending head or bell with supports and operating means in elevation; and

Figure 3 illustrates a d agrammatic view of the crane with dotted line showings of atas zontally disposed arms 14 and 15 having their ends in spaced relation to each other. In order that acarrier or suspending device, whichwill be presently described in detail, may be properly guided for the purpose of depositing its loadat a station and.

further guided to engagement with the pouch carriers which it is to remove from the crane, two substantially horizontal rails.

or rods Hand 17 are attached to and carried by the arms 14 and 15 respectively. 'Preferably, the rails are oppositely curved at their rear ends for the purpose of producing a clearance between their ends s that the distributor or collector which depends from the transport will enter the crane without making it necessary for the distributor or collector to register too accurately with the axis of the crane. In other words, the flared rear end of the crane would allow cons1derable latitude of movement for the distributor or collector in entering the-space between the rails and the rails will act as guides to direct the distributor or collector to the interior-zone of the crane. The forward ends preferably flared slightlyas shown at 18 and then conve'rge at their ends, but their ends are .in spaced relation to each other so that a clearance-is produced through which "of the rails beyond the arms 14 and 15 are the suspending means may escape from the crane. The rear ends of the rails may be provided with a suitable support 19, but as the details of construction of the support .are immaterial, they will not be described.

The illustration is suflicient for an understanding of one embodiment of a support bythose skilled in the art.

In order that pouches may be supported on the crane for removal by the collecting 22 and 23 from which pouches such as 24 2 tion, the

. gaging it while the pouches are bein 001-.

may be suspended when the crane is set to permit collecting of the pouches.

As shown in the drawin the yoke en gages and is supported by t e crane and the loop 21 is located slightly in advance of the space between the front ends of the bars 16 and 17 so that as the collector passes the ends of the bar,"it engages the loop to later remove the yoke from the crane.

In the present embodiment of the invenpouch suspending and delivering device an the pouch collector comprises a head or bell 25 that is supported by suitable cable or rople 26 depbending from the transport and t e said ell should be of such size as to prevent the loop 21 from disenlected. The head has an internal ange or web 27 having a pivot 28 therein on intended to support pouches to be droppe or delivered as illustrated in Figure 1. Preferably, the pouches will be rovided with loops such as 30 or other hoo engaging elements so that the pouches will be suspended from the head until the hook is manipulated to release the load. As here shown the hook is held in operative relation to support the load. by a latch 30 movable on a pivot 31 within the head. The

latch is held approximately parallel with the lower edge 0 the head by a flange or wall 32 and the latch is of such length as to 'roject underthe hook. The latch pref' era 1y has a' camming surface 33 that will permit it to raise the hook when the end of the latch remote from the pivot is moved upwardlyin the headandthe said move- 5 ment will raise the free end of the hook until the latch passes the end of the hook after which the said hook will be released and it will swing downwardly andpermit the dislodgment of the pouch f om the hook. A

rope or cable 34 is nnected to the latch and it extends through an aperture 35 in the bell and must of course reach to an operator on the transport, which operator upon pulling the cable 34' when the parts are 1. In a. pouch transfer, a head havin a'lfi suspending means extending therefrom near its transverse center only, a pouch supporting and releasing means therein, and means extending to the releasing means whereby it is manually operated, the said releasing 8 means projecting from the head at a location near its transverse center, the outer surface of the head around the releasing means v and the head supporting means being unobstructed and capable of receiving and I supporting a pouch engagin element. which a. hook 29 is pivoted, the hook being 2. In a pouch transfer, a ead, a suitable supporting cable therefor, a pouch support pivoted in the head, a latch engaging a por-.

tion of the pouch support remote from its pivot for holding it in operative position, a flange integral with the head for holdin the latch in the said osition and'a latc movin means operative to disenga the latch em the pouch support, the sea moving means projecting through the head in proximity to the location of e support ing cable thereof.
