We give here, weeh by wccli, a terse description of sxtch of the many 

 ini^entioiis as ice think may he of use to our readers. Wliere it is 

 possible, the number of the patent is quoted, to enable those who 

 desire fuller information to procure the specification from the 

 Patent Office in Cursitor-street, Chancery-lane. We shall, gene- 

 rally speaking, confine ourselves to the more recent inventions ; but 

 it often happens that an article comes under our notice which, 

 although not quite novel, is ivorthy of mention for its utility and 

 ingenuity. In such a case we sliould not hesitate to refer our 

 readers to it. And wliile we thus increase theinterest of our pages, 

 we at the same time assist the inventors by giving greater publicity 

 to their inventions (Knowledge being a popular magazine) than 

 is accorded by the most excellent trade journals 



end of the etretcher-bar up or down the slot shown at the lower end 

 of t!ie central bar. The opening and closing is effected instanta- 

 neously by merely pulling apart or pressing together the two front 

 legs. It is claimed to be the only folding easel which will stand 

 firm on a polished floor without the aid of adjustable and compli- 

 cated ties. The easel is exhibited at the Inventions Exhibition, in 

 the East Gallery. 



PARALLEL ENDORSING PRESS. 



(Patent No. 16,397. 1884.)— This invention, by Mr. Harold 

 Savage, of Cheapside, London, E.G., has for its object the adap- 

 tation of the parallel press to carry movable type, which may be 

 altered at pleasure to any required wording ; to carry dates, 

 numbers, or other movable pieces, in addition to any set 

 wording which may form the ordinary die. The press will still 

 curry t'.? ordinary die, or any number of dies, the plates carrying 



LETTER-FILE OR BINDER. 



(Patent No. 5,102. 1884.)— The file illustrated has been patented 

 by Mr. A. Blackwood, of i'. Manor-street, Ardwiek, Manchester. It 

 is intended for the reception of letters and other loose papers. It 

 is made in box form, with a flange lid, keeping all papers placed 

 therein clean, free from dust, and in order. A " binder," consisting 

 of a piece of millboard, extends the whole length of the case, so that 

 the smallest size of paper may be placed in the largest sized file and 

 kept in position. The front, C, of the file, as soon as the lid is 

 raised, falls down, giving easy access to refer to any paper, which 

 can be taken out or replaced, or added to, without trouble or 

 injury. The files may be made to hang up on wall, or book- 

 shape, to stand on shelf. They are composed partly of wood 

 and partly of millboard ; they are covered with cloth or leather ; a 

 hinge is formed at the up]')er edge, and placed at the back of the 

 file ; an eyelet-hole is placed at each end of the clip or binder, at 

 the lower edge, and two small rings are fixed in the back of the 

 file in corresponding position to the eyelet-holes ; a round or flat 

 elastic band is passed through the holes and rings, and then tied, 

 the effect of which is to bring the clip or binder firmly on the papers 

 in the file and keep them in position. A jointed ring is jjlaced ir, 

 the binder, by which it is very easily raised. No damage to papers 

 can occur, there being no spikes or anything that can injure or 

 deface them. 



The invention is practically designed, and should prove of great 

 value to those wishing to preserve letters, &c. The fact of their 

 being entirely covered up, and the means provided for hanging the 

 file on a nail, are good recommendations. 



THE HATHERLEY EASEL. 



(Patent No. 8,602. 18S1.)— This easel, patented by Mr. C. A. 

 Jones, of Hatherley Court, Gloucester, has several features, of 

 which the following are the chief. All three legs arc connected 

 together in such a manner as not to interfere with the opening 

 and closing of the easel, and at the same time to prevent the pos- 

 sibility of accidental collapse. The width at the top, when open, 

 enables a short easel to do the work of a much longer one of the 

 ordinary kind. In all positions the easel is perfectly rigid. The 

 ledge may be adjusted to a nicety at any height by means of a 

 thumbscrew at either end, without the aid of holes or notches in 

 the easel. The inclination can be adjusted liy merely sliding tVe

 the die being interchangeable. The pad is made reversible, so 

 that the ink on one side being exhausted, it may be turned over 

 am! used without the trouble of re-inking. The press is provided 

 v;ith four guide-rods of suflicient length to admit of a die-plate 

 about half an inch thick being secured to the top plate, and to 

 allow the die-plate and die to fall fair on the jjad. The die- 

 plates are secured to the top plate by a screw fixed in the 

 centre of the die -plate, this screw passing up through the 

 central hole in the top plate, the handle is screwed on and the plate 

 held secure ; the side pieces, or flanges of the top plate, being a 

 little lower than plate itself, ensure the die plate being held in a 

 true hue. For ordinary dies the plate is cast solid, or with a solid 

 face. For carrying a date, or other movable pieces in addition to 

 the ordinary die, a slot is cut in the die-plate, of a suitable size. 

 For carrying movable types, the plate is so cut away as to leave a 

 frame or "chase" only, into which the types may be set, and secured 

 by means of screws, &c. The pad is made reversible ; a metal plate, 

 having two lugs or projections, is covered on both sides with cloth 

 or felt. The pad is held in its place by the lugs, which fit into 

 corresponding recesses cut into the flanges or sides of the pad bed. 

 The parts are all made interchangeable ; the die-plate may be 

 easily and quickly changed by unscrewing the handle ; the plates 

 may then be changed, and the handle screwed on again. The total 

 weight is about 6i lb., and the press appears capable of doing all 

 t'nac is said of it.
