MAlL-BAG-DELIVERY DEVICE.

Specification of Letters Patent.

Patented Jan. 22, 1907.

Application filed November 21 1906. Serial No. 344,386

To all whom, it may concern.-

Be it known that I, PETER J. A. SoI-INooR, a citizen of the United States, and a resident of Holstein, in the county of Ida and State of Iowa, have invented. an Improved IVIail-Bag- Delivery Device, of which the following is a specification.

This invention relates to mail-bag-delivery devices for railway-cars and it consists, substantially, in the construction, organization,

and combination of parts hereinafter described, and illustrated in the accompanying drawings.

One object had in view is to rovide devices of this character which sha 1 be simple detail view of the track-derrick or mail-bag support viewed as indicated by the arrow in Fig. 1that is, looking at the free end of the derrick-arm when it is adjusted to position adapted for holding a mail-bag ready to be taken. up by 0 eration of catching devices or crane carried y a mailcar. Fig. 4 is an eX- ternal view of a maiL-car door and adjacent portion of the car side. In the view the bagcatching device or crane is shown arranged in place on the car. Fig. 5 is a detail plan view of the crane-head and a portion of its su porting-arm.

efore proceeding with a more detailed description it may be stated that in the form bf my improvements herein shown I employ a specially-constructed derrick at each of the railway-stations or other places at which the mail-bags are to be delivered and taken up by the devices on the car. On the car I employ a specially constructed oscillatory catching device or crane adapted to be adjusted into position fortaking up a mail-bag supported in position on the derrick adapted to be taken up and delivered into the moving car, the catching device or cranebeing also adapted for depositing a mail-bag from a moving car, leaving it supported on the track -.derrick ready to be removed therefrom.

In operation a mail-bag is suspended from one of two supports on the derrick at the station or railway side, and a bag is also suspended from the head at the free or outer eX- tremity of crane, the latter obviously being adjusted outwardly from the side of the car. As the car moves along the mail-bag on the derrick will be taken up by the crane, and the mail-bag on the crane will be taken up by the derrick.

In the following detail description of my invention reference is had to the drawings by the designating characters marked thereon.

In carrying out my invention I employ a derrick A, constructed-with a post B, supported, in upright position near the railwaytrack, locating same at. a station or other desired position of mail delivery or deposit.

On the upper end of the post B a horizontallysupported arm O is provided the same being supported adapted to turn one hundred and eighty degreesin other words, ninety degrees on its support from adjusted position thereof ready to take up a mail-bag or support a bag ready to be taken up by the crane on a passing car.

D designates an arm located on the post B above position of the arm O. The arm D has pivotal support near one end thereof on trunnions E, fixedly secured to the post B. In constructing the pivoted end of the arm D, I employ two similar castings F, adapted to be bolted together and fashioned at one end adapted for attachment of the arm member D. The other end of the casting-that is, its extension beyond the pivotal supports E-is weighted adapted to overweight the member D portion of the arm, as will be understood, upon reference to Figs. 1 and 2.

The object of thus constructing and support- 9 ing the arm D is chiefly to adapt its mail-bagsupporting end to be swung upwardly when set free by removal of a bag thereon, as indicated by the arrow in Fig. 1. At the outer end of the vertically-swinging arm D, I secure irons G, constructed with oppositelyprojecting flanges or jaws H. I

The lower arm C is constructed with a member C, having an iron or casting I at its inner end, the iron I being constructed in two similar parts adapted to be bolted together and adapted to clampedly hold the adjacent end of the arm member O and, further, to surround or have journaled support on the post B, permitting free lateral turning there- TOC arms W (see Figs. 3 and 4) will engage the rope Q and the latter, through forward impact movement, be forced between the dogs A A to position against the roller A Obviously continued motionof the car will pull the rope-head Q from between the jaws H on the derrick-arms D, whereupon the latter will by gravity find supporting-seat upon the said forward arms W and be retained in the seated position stated through confining action of the rear side of the dogs During operation or movement of parts just described the bag suspended from the rear arms N of the device U will carry the rope Q between the arms P at the outer end of the derrick-arm O and force same between their dogs P" to position contacting the stop device or roller'PK Now it is apparent that, as both sides of the abutting ends of the dogs A are rounded, as the crane take-up device is carried along the rope Q will be pulled, forcing the dogs A apart, and thus permitting the rope-head Q to be seated upon the arms P at the outer end of the derrick-arm C.

'ihe dogs P on the bag-supporting arms P being constructed with rear flat sides similar to the like dogs A on the crane tal e-up d evice U, obviously the bag-holding rope Q" will thereby be held, and thereby insuring detachment from the crane take-up arms.

I claim 1. In mail-bag-delivery devices for cars, a derrick at the station of delivery, comprising a horizontally-adjustable arm, a verticallyadjustable arm, means adapted to hold the arms in bag-supporting position, means effecting vertical adjustment of one arm when it is released, means adapted to hold the vertically-adjustable arm drawn down to bag holding position, means adapted to secure both the arms at bag-holding position, and means providing support for said arms.

2. The combination in a mail-bag delivcry for cars, of a derrick comprising a post, an arm at the upper end of the post, said arm having pivotal support' 011 the post providing it with vertical adjustment, a

counterweight at one end of said verticallyadjustable arm, a lower arm on the post, the lower arm having horizontal adjustment, oppositely-projecting arms at the bag-suspending ends of said adjustable arms, means for attachment to a bag, adapting the bag to be suspended on the derrick-arms, and removed therefrom, and a crane on a car,

adapted to deliver a bag to supported position on the derrick-arms, and also adapted to take up a bag from supported position on the derrick-arms.

3. The combination with a derrick, comprising horizontally and vertically adjustable bag-supporting arms, and means adapted for suspending the bag, of a crane carried bya car, the crane being adapted for adjustment to deliver and take up bags, a take-up device at the outer end of the crane, the take-up device being constructed with oppositely-projecting bag-engaging arms and dogs on said arms adapted to secure the bags at suspended position.

4. A mail-bag-delivery device, comprising a post, horizontally and vertically adjustable arms on the post, the vertical arm having pivotal support, and counterweighted at one end, a shoulder on the post having a pro j ection on its upper side, the inner end of the horizontally-adjustable arm being provided with a recess adapted to receive said projection on the shoulder, and stop devices whereby to limit movement of the horizontally-adjustable arm.

5. A derrick constructed with upper and lower supporting-arms, jaws on the upper arm, parallel transversely-arranged project ing arms on the lower derrick-arm, dogs and a stop device on the parallel arms, and projecting pins on the lower derrick-arm, said pins being located projecting from one side of the lower derrick-arm.
