rendered completely suitable for cllher

To James Harcourt, of Bimmiglinm, 



in the County of Warwick, Brass- 

 founder ; for an Improvement in 



Castors applicable to Tables and other 



Articles.— Suno 21, 1820. 



This improvement in castors, appli- 

 cable to tables and other articles, 

 consists in the adaptation of anti-fric- 

 tion rollers, which are intended to take 

 off tlie friction when the castors turn 

 liorizontalh'. The principal novelty 

 of this invention, and, indeed, that 

 alone which is claimed, consists in a 

 conductor guide-plate, by which the 

 action of the auti-friclion rollers are 

 confined to a certain course, and 

 enabled to revolve without nioviii^ 

 upon poles or axles. Its action is as 

 follows : tke lepj of a piece of furniture 

 beinj;; fitted into the socket, its weight 

 would rest upon the plate of the wheel- 

 carriage ; and, as the castor turned 

 horizontally, very considerable fric- 

 tion would take place ; but, to prevent 

 this, the anti-friction rollers are so 

 placed, that by bearing; upon the bed, 

 and receiving the whole weight of the 

 socket by its false bottom, the anti- 

 friciiou rollers, conducted by the 

 moving guide plate, take off the fric- 

 tion which would olherwise be pro- 

 duced by the bearing of the socket. 



To Samuel Fletcher, of Walsall, for 



fin Improvement on or Addition to 



Sadd/fs, Saddle-straps, Saddle-girths, 



and Saddle-cloths, by the Application 



cf certain Jmown Materials hitherto un- 



rtsedfor that Purpose. — July 11,1 S20. 



The improved girth consists of an 



apparatus, by the use of which saddles 



are more permanently secured on tlie 



horse's back than can be done by the 



girths heretofore in use. 



The web required for these uew- 

 invented girths differs in no respect 

 from that in general use, and is 

 attached to the apparatus already de- 

 scribed in the ordinary way of making 

 girths. The iiDproved saddle-girtlis 

 being now comi)leted according to the 

 above description, they are to be buck- 

 led to the saddle in the usual masimr, 

 and, when it is girthed tight upon the 

 horse, the strap with the buckle 

 attached to it should be drawn about 

 one inch and half out of the leather 

 case at each end of the girliis. It will 

 then be found, that, when the hor.se's 

 carcase shrinks up, the elastic nature 



[Feb. 1, 



of the girths being brought Into action, 

 will still cause them to press closely to 

 the horse, and thus prevent the saddle 

 from moving out of its proper place. 



To James 'Dv.l.VZXV,ofWardour-street, 

 Musical Instrument-maker ; for cer- 

 tain Improvements on Harps. 

 The pedals arc arranged in any 

 way that may be found convenient, so 

 as to allow the leading rods or wires to 

 pass up through the pillar to the neck 

 of the harp. Mr. D. docs not claim 

 any particular construction or arrange- 

 ment of the pedals, or to the move- 

 ments to cflect the shortening of the 

 strings to produce the semi-tones ; 

 but ho confines his claim entirely to 

 the new mode of making or arranging 

 the bottom part or pedestal of the 

 harp, and tho branched or divided 

 part of the pillar as therein described, so 

 as to obtain a greater length of sound- 

 ing-board, and a more perfect connec- 

 tion between the pillar and iho pedes- 

 tal, in proportion to the size of the 

 harp, than by the means at present 

 adopted in the pedestals and sounding- 

 boards of tl)e harps in common use.
