ATuosrBEn'rc ENGINE.

To'all whom'fitmay concern." y

Be itknown that we, WILLIAM H. SPEras andfAN'roN HoLM citizens of the Uni-ted States, residing-at li'aterson, in the county of i 5 Passaic and State of New Jersey, have 'inl vented certain new. and useful Improvements c `1n Atmospheric Engines; and we do declare ,f the following to be a full, clear, and exact de- 'scription of the invention, such as will enable `110 others skilled in the art to which it appertains to make anduse the same.

.. Thisinvention vrelates to that class of engines in which the piston is driven in one di-' Lrection by atmospheric ressu're, the pressure yduced be ow that of the atmos heric by the condensation of highly rareiie air admitted -th`ereto.' l y' .The object of the present invention is to obtain ajgreatei'amount of work in an engine witha less consumption of fuel b supplying thereto a workingfcharge ofhig ly rarefied air and in quickl 'condensing and dischargthe same, T ese objects areobtained by iirst drawing the flame and products of combustion-from asu'itable bur-ner, into one end f of the cylinder, next in displacing the heated air from the hot end of the cylinder and deliverin it into the opposite or cooler end thereo and finally after a movement of the piston has been effected bythe condensation of the highly rarefied air and gases in discharginahesame from the cylinder.

ith these and other objects in view, the

-fiifi'nvention consists of certain novel features of,1 construction, combination and arrange# n, .ment of parts, as'will -be more fully described g and particularly `pointed out in the appended f vr4,0/*01 `In the accompanying drawings, Figure 1 is fa plan view lof an engine c'onstructed'in accordance kWlth the 'invention with partsv c 'broken away; and Fig'.4 2 is acentral longi- 1 Y tudinal section thereof. 1

on the o posits side o the piston being retween the partition and top wall of the cylnder. Th-e front end of the c linder is pro vided withv two longitudinaly spaced ap proximately rectangular ytransverse openings 6 and 7 respectively,' the former of which 1s rv1erasneed May e5', 190e.

formedin the top wall and partition 3 and 4 and communicates with the extremefrontv end of the cylinder land the latter of. which is formed in t e top wall of the cylinder and Ycommunicateswith the front en d ofthe hot.. vairlna'ssage `5. A piston. 8 of thepro er form is arranged in the 'cylinder-'beneath t e parti-A 'tion' or' Wall nthereo'r'. This piston is provided with the usual rod erstem 9 which exs tends through the rear wall of the cylinder and is connected with afpairofflaterally spaced links 10 fixed to the crank 11'- of a crank shaft 12, the latter being journaled in suitable bearings 13 mounted upon thebase.v

The numeral 14 indicates the .slide lvalve whichis mounted upon thei topwall` of the cylinder to cover theopenings (j` and 7, this -valve being so constructed las' to establish com'hiunication between these openings and consequently' between 'opposite .ends of the sinF cylinder iiv'hen in one lfposltion and to cut-off communication in the next position.' This valve is actuated in the roper movement in the work of the engine y a valve'stem 15 .which extends through .-an u iight guide plate 21- arranged at the rear en ofthe cylinder and is connected with the -upright arm 16- of a bell crank suitably mounted at the junction of its arms upon the base, the other arm 1'7 of l the bell crank carryinga roller 17 which is dis osedv in the path of a cam 18 .of the proper s ape fixed to the crankshaft 12.

Acoil spring 22 is arranged between the guide'plate vand a collai` 23 formed on the .valve rod or stem for movin the latter and the slide valve forwardly. iiamcgenerator 19-of any suitable form is mounted on the base in front ofthe cylinder v and, ahoodi20 arrangedv in position t'o conn voil burner or duct the flame and heated air directly'to the opening 6.' Ai1y-.-V wheel 18 is arranged at one end. of the crank shaft7V the purpose of which will be e vident. ,f i f In the operation o'fthis engine thus simply constructed as the piston 8 moves outwar the slide valve moves in thes'am'e direction 4 and discloses the opening G thfrou hwhich is fdravvnv the hotfilame frox'n` the. u'rner 19.

As the piston reaches the endof its outward stroke the slide valve closes the opening 6 andshuts ofi the inflow of hot'ai'rdllto the roof cylinder .and at the same time establishes communication between the openings 6 and to condense until the iston hascompleted 7, the piston in' receding forcing the rarefied air through saidopenin s' into the hot air passage and'behindt episton into the cooler end-of' the cylinder, Where it'continues its return stroke and as' 'thereby expelled .y all of the rareed air from the hot end'ofV the cylinder vto the cooler end thereof, under Whichconditions the vinternal ressure in the pylinder is far belowr atmosp eric pressure.

en the pistonreaches the end ofits return stroke the valve 14 again opens with the result that the full atmospheric pressure is brought to bear uponf the piston to force it outward and cause it to draw in a fresh sup- Aj ply of heated air'. 'AsA the piston moves voutv-topwallof the'cylinder. v

(Ward the charge of condensed air is forced 20 throughthe exhaust port 24 Vformed in the rom the foregloing' description, taken in lconnection with t e accompanying drawings, the constructionand operation of the inven-l tion Will be readily understood Without requiring a more extended explanation.'

Various changes in the form, proportion and the minor details of construction may be lresortedtowithout departing from-the princi-ple orsacn'icing any of the advantages of valve for controllin der, a piston arranged therein, a flame gener# ator near the cylinder, means for directing the llame from the generator in one end ol' the `cylinder in front of thepiston, a slide fiame into the cylin er, and for establishing or cuttin oi? communication between 'opposite en s thereof, a longitudinally dis iosd valve stem for operating the'slide valve, n, spring around the valve stem to move thc valve in one direction, an upright bell crank lever pivotally mounted near the cylinder.

and connected with the valve stem and l means for rocking said lever in one'direction against the .action of said spring.
