MAIL-BAG- DELIVERER.

Specification of Letters Patent.

Patented July 12, 1910.

Application filed April 6, 1910.. Serial No. 553,776.

. useful Improvements in Mail-Bag Deliverefs; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to mail bag deliverers, and is designed as an improvement on my Patent No. 948,217, patented February 1, 1910.

To more fully understand the invention reference is had to the accompanying drawings', and the particular features of novelty will be more succinctly pointed out in the claims.

In the drawings in which like characters designate the same parts in the several views Fi re 1 is a lon itudinal section through a hollow vertical standard, the operating mechanism of the mail deliverer being shown in side elevation. Fig. 2 is a flag mentary view showing the locking dogs positioned with relation to the hollow support. Fig. 8 is a section on the line 3-3 of Fig. 1, and Fig. 4 is a detail perspective view of the carrier.

In the present invention I have illustrated a hollow standard or pipe 1, which may be provided with the supporting feet 2, secured to a suitable base by bolts or otherwise, and it is evident that stay rods 2 may also be employed for anchoring the vertical support.

The upper end of the support is slotted, as at 3, and adjacent the slots are the pivoted locking dogs 4' adapted to swing laterally in a vertical plane.

In the drawings the movable carrier consists of the elongated member 5 having a neck portion 6 of a width adapted to fit snugly in the slot 3, and inside of the hollowstandard is a curved plate 7 disposed against said neck and securely atlixed to the elongated member in any suitable way, illustrated in the drawings as comprising the bolts and nuts 8.

On the outside face of the elongated memher, and held in position by theupper bolt 8, is a bracket or support having an upturned ofiset portion 9 adapted to engage the underneath face of the upper trigger arm 10, in order to limit the downward movement of same. The upper trigger arm 10 is suitably pivoted or hinged, as at 11, to the elongated member 5, and is provided with a rear extension or arm 12 extending through said slot 3 into the hollow standard and provided with a suspended weight 13. The lower trigger arm 14 is similarly pivoted or hinged, as at 11, to the elongated member 5, and this lower arm is provided with rearwardly extending otfset strips or fingers 15 adapted to rest on top of the lateral arms of the supporting dogs a and hold the carrier in its uppermost position when elevated.w These fingers extend from both sides of the lower trigger arm and straddle the elongated member, as shown in Figs. 3 and 4:. They also slightly diverge, as shown in Fig. 3, to properly engage the horizontal arms of the do s. I6 designates suitable,triggers, and in the drawings have simply been illustrated as shown in my former patent as consisting of laterally swinging members pivoted on the ends of the trigger arms, and having projecting fingers adapted to receive the rings at the top and bottom of the mail sack.

In the present construction the movable carrier is shown as suspended by means of a bail 17 secured to the end of the cable 18, reeving over a pulley 19 journaled in the upper partof the standard, the cable 18 passing out through a suitable opening 20 in said standard. The pulley 19 may be journaled in any suitable way, but in the drawings this has been simply illustrated by means of a bifurcated bracket 21 secured by means of a nut or rivet 22 to the top of a removable cap 23.

In Fig. 1, the carrier is shown in its uppermost position with the mail bag in position to be delivered, and in Fig. the trigger arms on the carrier is shown when the mail bag has been delivered and the carrier falls to its lowermost position, indicatedat a.

In its lowermost position it will be obvious that the carrier may be easily reached by the operator,with0ut the use of a platform or ladder, and when the mail bag is to be placed into position the trig or arms are swung forwardly toward eac other, the

movement of the upper arm beinglimited by 4. the position of the support 9 and the length of the bag being compensated for by the unrestricted vertical movement of the lower trigger arm. The mail bag being placed in position on the triggers, as clearly shown in Fig. 1, it will be obvious that the carrier may be elevated to its uppermost position by slightly hauling on the cable 18, and by the structure illustrated practically the only weight to be elevated is that of the mail bag plus the light weight of'the carrier.

As the carrier is elevated with the tri ger arms in their set position, when the 0 sets 15, engage beneath the lateral arms of the supporting dogs 4 (with which they are in vertical alinement) the ends of the dogs are swung outwardly, as shown in dotted lines in Fig. 2, so that the offset fingers 15 ride above the lateral arms of the dogs, when the latter swing back in place and are in position to support the offset fingers 15, and hence the carrier. Suitable stops are provided to prevent the lower arms of the dogs from swinging inwardly. These stops are illustrated in Fig. 2, as at 4, where the pin that forms the stop is bent over and also forms the axis for the swinging dogs.

When the collector arm on the train strikes the bag it will swing the triggers 16 in a horizontal plane, the bag being delivcred without any strain on the apparatus, and as soon as the bag is delivered the upper arm will swing upwardly, owing to its counterbalanced weight 13, and the lower arm will swing downwardly, owing to its weight, thus moving the fingers 15 away :t'romthe supporting dogs, allowing the whole carrier to drop into position for inserting a new bag in place.

In Fig. 1 there is also illustrated a counterweight cooperating to assist in elevating the carrier and mail bag, the counterweight being of a weight slightly less than the weight of the carrier. Any suitable form of counterweight may be employed, and this has been simply illustrated as an oval-shaped lead 18 carried by the flexible member such as a chain or cable 18, and from the position shown in Fig. 1 it will be obvious that when the mail bag is delivered the weight of the carrier will cause it to fall down to its lowermost position, the weighted lead 18 retarding its movement and providing against shocks. The counterweight also, of course, assists in elevating the carrier and bag.

Having thus described the invention, what I claim is 1. In a mail bag deliverer, the combination of a hollow upright provided with a longitudinal slot, a movable carrier operat-v ing along said slot, an upper and a lower trigger arm pivotally mounted on said carrier, means for detachably securing a mail bag on said trigger arms,-an extension on said upper trigger arm disposed within said scape 1 hollow support, a weight suspended on said extension,'means for elevating said carrier, and means for holding said carrier latched in its elevated position, substantially as described.
