[August, 



For " an Improvement in the connecting rods for connrctins: the crank 

 pins of three or more dricing wheels of locomotives." Hulmes Hiuckley, 

 iiosluu, Mass. 



The object of tills Improvenipnt is to connect three, four, or more, driving 

 wheels with a single connectin;^ rod, and permit those h-'tween tlie two 

 end ones to have a veriical and lateral play, which is eliVcted by having 

 the crank pins of the interriicdiaie wheels work in boxes that slide verti- 

 cally in the comiectint; rods, tlie said crank pins being made of suDicient 

 Jenf^tli to give end play to the axles. 



Claim — " I claim makin;; the bixes to slide vertically in the connecting 

 rod, in combination with extendmg or lerii^tlM'ning ilie rrarik piiH of the 

 wheels beyond the siid boxes, so as to slide throui^h them in the direction 

 of their axes, as set forth ; ihe whole being for the purpose of convening 

 all of the several wheels of the engine into drivers, as described, 



¥or " Imprnremints in the aurilmnj steam engine for supplying steam 

 ioilers irilh water." John Cochrane, lialtiniore, Md. 



The pateolee says, " The intention of an auxiliary supply engine is not 

 only to supply water lo a hjiler, hut to preserve the same at a uniform 

 height therein, widiout its being alTeeted hy any irregularity in the con- 

 sumption or evaporation of that fluiil; said auxiliary engine slopping and 

 starling, and working; quickly or slowly, as the demands of the boiler may 

 require. Under the arrangement thai I prefer, the admission of steam to 

 the auxiliary engine is goverued by a float and balanced valves, placed in 

 a chamber outside the boiler, but commuMicalin; therewith by l»o branch- 

 es, one above and the other below the water line ; so that llie water may 

 have the same level boUi in the chamber and boiler. The float is furnished 

 with a tubular stem at bottom, openiug into it, for the purpose of carrying 

 off any leakage ; this stem passes out iliningh a stufling-box in the lower 

 part of the chamber, the arrangement of tins part being subslaniially Ihe 

 same with that represented and described in the speciticaiion and drawings 

 accompanying letters patent of the United Stales, griuled to me on the 

 13th day of July, lS4t, for regulaling the supply of water in steam boil- 

 ers. The float, however, may be oilierwise arranged and modilied, the 

 only requisite being lliat its action on the steam valve should be goverued 

 by the height of water in the boiler. 



"It is not pretended that an auxiliary engine for the supplying of water 

 to steam boilers is in itself new, such engines having been heretofore em- 

 ployed for that purpose ; but I have, as 1 believe, succeeded in so con- 

 structing and arranging the parls of such an engine as to obviate the main 

 difficulties heretofore encountered in the alteiupts lo employ them,'' 



Claim. — ■' Having thus fully described the nature of my improvements 

 in the auxiliary supply engine, wliat 1 claim therein a-i new and desire to 

 secure by letiers patent, is, first, the manner herein described of complet- 

 ing the stroke, or traversing mulion, of ihe valve, by the commencing 

 return stroke of the piston operating on Ihe spring arms, substantially in 

 the manner and for the purpose herein set forth. 



" I likewise claim tlie niauuer of regulating the stroke of Ihe water 

 pump, by adjusting the same by means of a valve, or cock, as set forth, so 

 tiiat a smaller and regulated quantity of steam shall be admitted to the 

 lifting, than is admitted to the forcing, side of the piston, as described." 



For " an improved method of supplijing water to steam boilers ht/ means 

 of an uuxUiarij steam entwine." Isaac N, Cirllin, Washington, D. C. 



Claim. — " What I claim as new, and desire lo secure by letters patent, 

 is the combination of the float with the valve, steam engine, and supply 

 pumps, substantially as herein described, so that the depression of the 

 float, caused by a deficiency of water, shall open a valve, and that Ihe 

 steam which escapes through said opening shall drive an engine to operate 

 the supply pumps." 



VoT " a hydrostatic power machine." John Gregg, Rochester, Monroe 

 county, N. Y. 



The patentee says, — " There are many siiiialions in which the power of 

 water can be obtained under a very considerable head which, from local 

 rauses, cannot be rendered availilile by means of waler wheels without an 

 expenditure of money greater llnu coiiM be made wilh prudence; it is 

 principally in such sitiialiuns tliat it is inlended to employ the machinery 

 jnvenled l)y nie. To eli'ect this object, I employ two cylindrical or other 

 formed waler receivers, into which receivers, water is alternalely admitted 

 under any desired head, and is made by its pressure lo condense alnios- 

 plieric air, which air, so condensed, is lo be conveyed by tubes to a cylinder 

 furnished with a piston, valves, and other appurtenances, similar to those 

 usually employed in a steam cylinder; the air being, in fact, sub,tiiuted 

 for steam in such manner as that an ordinary sleam cylintler* will not re- 

 quire any alteration to adapt it to use by means of condensed air." 



For " Improvements in the sleam engine." Rslpli Pomero'y, Belleville, 

 Essex county, N. J. 



' ■ Within the cylinder of this engine there are four pistons, the two end 

 ones being conuecled together and operating one crank ; and of the other

two, each operates a separate crank ; and the three cranks being on th» 

 same shaft and dividing the circle into three equal parts. All tlie pistoQ 

 rolls, except the last, are hollow, and pass through each other, and the 

 steam is to be admitted alternately lo the dilTerent pislnos, and so cut oOT, 

 that whilst it is expanding in one division, another division is receiving the 

 sleam directly from the boiler, but the manner of operating and arraogiog 

 the valves for this purpose is not described or represented. 



Claim — •' What I claim as my invention and deiire to secure by letters 

 patent, is combining four pistons, conitructed and arranged subslantiallj 

 in the manner set forth, in one cylinder ; said pistons being connected with 

 three cranks placed at about aa angle of l'iO° from each other, all M 

 bereio described."

MOULDING IRON. 



William Mitshet and Robert Mushet. iron-founders, of Dalkeith, 

 Scotland, for " Improvements in moulding iron." Granted Dec. 10, 1845 ; 

 Enrolled June 10, 1S4G. 



This invention consists in the application of stampers and rollers or other 

 suitable apparatus for pressing the sand into the boxes instead of perform- 

 ing such operation by hand as heretofore. In carrying out this invention, 

 the patentees propose lo employ a machine having one or more stampers, 

 or rammers, worked by means of "ccentric or other convenient means, or 

 the same may be effected by a roller or rollers in the following manner: 

 that is lo say, the sand after being put into the lower box, is placed npon 

 a carriage and passed under the machine, for the purpose of compressing 

 it into ihe box, the mould being inserted and suitable sand employed to 

 form the parting; the top box is theo put upon the lower one and filled 

 wilh sand in Ihe usual manner, when it is again suiijected to this improved 

 mode of ramming, after which the mould is finished in the ordinary man- 

 ner. The patentees state that the moulding of railway chairs ami other 

 similar articles, when a great number of the same sort are required, will 

 be greatly facilitated by the process above described. 



STEAM ENGINE IMPROVEMENTS. 



William M'Naiigiit, of Glasgow, Scotland, engineer, for" certain «m- 

 prorements in steam ingines." — Granted December 10, 1815 ; Enrolled 

 June 10, 1840. 



This invention, which relates to certain improvements in steam engines, 

 consists in the application of what the inventor terms a non-condensing 

 cylinder, in adJilion to the present c\ Under in beam engines, which 

 present cylinder may be supposed to be the condensing cylinder. In car- 

 rying out these improvements, Ihe patentee proposes to have a second 

 sleam cjlinder placed between the centre of the beam and the connecting 

 rod. the piston rod of such cylinder being attached to the beam by means 

 of links, and to that part thereof about midway between the connecting 

 rod and beam gudgeons. This auxiliary cylinder is provided with a valve 

 of the ordinary construction, and worked by a rod, one end of which is 

 attached lo a lever keyed upon the weigh shaft of the ordinary cylinder, 

 the other end being attached to a lever on the weigh shaft of the auxili- 

 ary cylinder, so that the valves of both cjliuders are worked by one ec- 

 centric. The action of Ihe engine is as follows : that is to say, ihe steam 

 from the boiler is first ailraitted into the auxiliary cylinder, and having 

 acted upon the piston so as to force the same from the top of the cylinder 

 to the bottom, it passes through the eduction pipe into the ordinary cylin- 

 der at the opposite end of the beam, and into such cylinder at Ihe upper 

 part thereof, so as to force the piston down after performing the stroke ; the 

 sleam passes through the eduction pipe into the condenser, which is of the 

 ordinary c instruction. So that the steam from this additional or auxiliary 

 cylinder, after having performed a stroke — say the up stroke — passes from 

 the underside of the piston of that cylinder to the underside of the piston 

 of the ordinary cylinder, which latter, it will be observed, is at the bottom 

 of its cylinder when Ihe oiher is at the lop, so that the luventor works with 

 high pressure steam iu one cylinder and low pressure in the other, from 

 which latter the steam passes into the condenser. 



The specilicilion shows a mode of applying the invention to marine steam 

 engiues, in which case there is a cylinder placed at each end of the beam, 

 one of which, that is, the high pressure cylinder, being somewhat smaller 

 in diameter than the other ; by this means the power is said to be mure 

 equally distributed than in engines having but one cyliuder. 



R.4ILWAY CARRIAGE WHEELS. 



JosF.ni RoMNALD UozF.K, of Clieapside, mechanic, for "Improvement* 

 in Ihe coiixlruct'vn and application of railway carriage wheels."— Gcaated 

 January li ; Enrolled .June 24, 184G. 



The improvements relate to the application of the flange of railway 

 wheels on the outside instead of on the inside of the wheel.
