Description of an improved File for Receipts and Letters, 

 By Richard White, Esq.^ of Essex-Street*. 



SIR, 



1- SEND herewith the model of a file for papers, which I 

 think will bcs found preferable to any in common use. A 

 voucher cannot be disengaged from the common file, with- 

 out defacing it by cutting it off, or by reuiovingmany others 

 to get at it; and to return it to its proper place is attended 

 with more trouble and inconvenience. All this is avoided 

 hy the contrivance in the file now sent, the wire of which 

 is passed through a cylinder, and fastened by a screw at the 

 Isottom. 



I am, Sir, 



Tour very humble servant, 



RICHARD WHITE. 



This file de- 

 scribed. 



Method of 

 using it. 



Explanation of Mr. Whitens improved Letter FilCy as sJiozcn 

 in Plate yin, Figs. 2 ^ 3,, 4, 5. 



This invention consists of a metal tube «, fig. 3, with a 

 convex circular plate soldered to its lower end, to keep the 

 papers from slipping off the file, and having attached to its 

 under side a piece of metal 6, fig. 4, with a screwed hole in 

 it, to receive a screw on the end of the wire c, fig. 5, the 

 other end of the wire being formed into a hook, sharpened 

 at its point, to receive the papers as usual. 



When any paper is wanted to be taken off the file, (in, 

 stead of taking oft" those above it, Avhich cannot be replaced 

 again without much loss of time and trouble, or, which is 

 still worse, tearing it off) the uppermost papers are to be 

 slipped up towards the top of the wire c, which must be 

 unscrewed, and, with the papers upon it, removed, asshpwn 

 in fig. 5 ; the paper wanted may then be taken away, the 

 wire replaced again into its tube «, and screwed fast, and 

 the other papers drawn down the tube as before. The up-
