CLARENCE B. STEWART, OF ALHAMBRA, MISSISSIPPI.

MAIL-POUCH LIFTING- ANI) DUMPING DEVICE.

To all whom 'it may concern.'

Be it known that I, CLARENCE B. STEWART, a citizen of the United States, residing at Alhambra, in the county of Washington, State of Mississippi, have invented certain new and useful Improvements in Mail- Pouch Lifting and Dumping Devices; 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 improvements in postoflice or mail car apparatus.

The principal object of the invention is to provide a simple device for mechanically lifting and dumping a mail bag on to the sorting table.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawings.

In the drawings: Figure 1 is a front elevation of my pouch dumping device showing the parts in normal position. Fig. 2 is a side elevation of the same. Fig. 3 is a side elevation showing the position of the parts when the bag has been lifted. Fig. 4 is a top plan View.

Referring particularly to the accompany ing drawings, 10 and 11 represent suitable uprights secured at any convenient point, and formed preferably of steel angle strips. These uprights are held to the floor by the fastening means 12 and braced by the bars 13. o A suitable bracing and spacing strip 14 is secured to the bars near their upper ends. Secured on the upper end portions of the uprights 10 and 11 are the journal brackets 15 and 16, these brackets supporting a transverse shaft 17. Secured to the uprights 10 and 11 at equal distances below the brackets 15 and 16 are the brackets 18, these brackets carrying a suitable shaft 19 on which is mounted a sprocket 20. On one end of the shaft 17 is a sprocket wheel 21 slightly larger than the sprocket 20, and on the opposite end of the shaft is an Operating Specification of Letters Patent.

Application led May 20, 1913.

Patented Apr. 28, 1914.

Serial No. 768,885.-

lever 22,- this lever carrying a suitable handlever grip 23 connected to a pawl 24 which engages with the stationary rack segment 25 mounted on the bracket 15. Secured to the segmental sprocket 2O and extending outwardly in a direction away from the uprights 10 and 11 are the converging rods or bars 26, the outer ends of which are connected together and carry a hook 27, this hook being adapted for engagement with the loop 28 on the end of the mail pouch 29. Trainedaround the sprockets 2O and 21 is a chain 30.

In operating the device, the handelever 22 is in the position indicated in Fig. 2, and upon releasing the pawl 24 by means of the grip 23, and lifting the said lever, the shaft 17 will be rotated. This will, through the medium of the sprocket 21 and chain 30, rotate the sprocket 2O and lift the hooked bars 26. The pouch 29 which is engaged on the hook 27 will be lifted above the table 31 and the contents of the pouch dumped onto the table.

The construction and arrangement of the parts are such that a small movement of the lever 22 will cause the hook 27 to be raised to a greater height than could be reached by a man in an attempt to dumpr the pouch. 'Ihe pouch is simply laid on the table in such position that the hook 27 engages on the hook at the bottom of the pouch, whereupon the operator grasps the handle 22 and lifts the lever and sets the same by engagement of the pawl 24 with the segment 25 so that the bag` is inverted and held in a suspended position. In this position, the contents of the pouch will readily be dumped onto the table.

IVhat is claimed is:

1. In a mail pouch dumping device, uprights, a shaft mounted on the uprights, a pouch engaging and lifting arm mounted on the uprights, means for locking the said shaft and connections between the lifting arm and the shaft whereby the movement of the shaft will communicate movement to the arm.

'IIS

l 5 an operating lever also carried by the shaft,

a sprocket mounted on certain other of the brackets, a pouch lifting arm carriedby the last named sprocket, means for holding the lever in Various eleva-ted positions, and a chain trained around said sprockets.

In testimony whereof, I affix my signature, in the presence of tWo Witnesses.
