UNITED STATES PATENT OEEIUEo BLANCHARD OHAMBERLAIN AND AUGUSTUS G. WRIGHT, OF BELLE- FONTAINE, OHIO.

IMPROVEMENT IN MAIL-BAG HOLDERS.

x Specification forming part of Letters Patent No. 155,709, dated October 6, 1874; application tiled September 10, 1874.

To all whom it may concern:

. Be it known that we,-BLANoHARD CHAM- BERLAIN and AUGUSTUS G. WEIGHT, of Bellefontaine, in the county of Logan and State of Ohio, have invented a new and Improved Mail-Bag Holder; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing, forming a part of this specification, in which- Figure l is a side elevation; Fig.,2, an end elevation; and Fig. 3, a detail view, in section.

The invention relates to that class of devices employed to hold mail-bags in close proximity v to a railroad-track, and consists in the improvement thereof, as hereinafter fully described, and pointed out in the claims.

A represents a post, vertically slotted, in a fixed or removable base, B, and made in two sections, c a. These sections are attachedadjustably by slots and a clamping-bolt and nut, D E, one sliding in a guide-band, F. G H are the pivoted arms, that have ahorizontal position whenthe bag is in place, but fall into a perpendicular one at other times. Between their ends are fastened the mail-bags, the lower end supported and the upper end Weighted in the usual manner. Instead of the catch and trip which are now used in connection with the weighted lever, we employ a pair of angle or arc plates, I I, one side of the angle aligned with and extending above standard orpost A, while the other projects rearwardly therefrom. In or near the end of this rear part i is pivoted the weighted lever G, so that when the weight is counterbalanced by the gravity of the bag the lever will be supported in a horizontal position by the top of standard. l v

In order to prevent the space between plates I I from becoming lled with sand, grit, or

other matter, we pivot the plate-cover J just above the lever-plates I and over the leverfulcrum, bending it into a shape that corresponds withthe circular edges i2 2 of plates I I, so that it may make a close tit and yet move out easily as the lever assumes a horizontal position. Y

By constructing the standard or post A in two adjustable parts, a a', the arms are easily accommodated to changes of grade in the track or road, While by. using the fulcrumplates I I we dispense with mechanism, sim,
