. n ROTARY ENGINE.
SPECIFICATION forming part ofl Letters Patent No. 259,966, dated June 2, 1882. Application inea February 20,1882. (No model.)
To all whom t't may concern:
Be it known that I, LEANDER J. WING, of
Lexington, in the county of Middlesex andk State of Massachusetts, have invented certain in such a manner that the cylindermay be bored out and nished, and when put together the parts will be in perfect alignment, and thus insure the most perfect action of the piston with the least expenditure of power, and
consequent wear of the piston or cylinder bore.
With this end in view my inventionconsists in certain features of' construction and combination of parts, as will hereinafter he described, and pointed out in the claims.
In the accompanying drawings, Figure l1 is a view in side elevationof an engine-cylinder embodying my invention, a portion of the cylinder being broken away to illustrate its interior construction. the innerv side of one section of a modified construction of cylinder. view of the same.
F represents the annular bore of the cylinder, in which the piston revolves. :The abut'- ment N, mounted on the shaft N', is caused to rotate within the slot L, formed in the upper section of the two half-cylinders shown in Fig. 1, which are joined together on aline with the abutment. ,z
The. two halves of the cylinder are each cou.- structed with fianges E, through which are inserted the bolts E9, by which the sections of the cylinder are securely fastened together.
Each halt or section of the cylinder is provided with four lugs or projections, E5, cast integral' therewith. These lugs or projections` are lo.- cated on opposite sides of each end of thehub portion of the cylinder-sections, and are arranged toproject outwardly from the divisionline of the two sections, so that .the lugs or projections on one section `will overlap and en- Fig. 2 is a plan view'of.
Fig. 3 is a sectional7 gage the hub portion of the opposite section and so that the lugs of one section will engage those of the opposite section. Thus it will be observed that this construction of parts prevents any vlateral or rotary displacement of the hub-sections, as the lugs serve to securely lock the two sections of' the cylinder against any independent movement. Y
In order that both sections ot' the cylinder may be cast from a single pattern, and, further, toallow them to be reversed in their posilions, if desired, the lugs or projections E5 on one cylinder are arranged to fit against the lower and plain faces of' the lugs E5 of the other section of the cylinder; or, in other words, the lugs on one cylinder are arranged above and the lugs of the other cylinder are arranged below the li ne of contact when locked together, and thus the two sections are rendered interchangeable. This feature ot' my withdrawn and the cylinder set up for use, with its piston, packing-rings, &c. When the sections of the cylinder are put together they will always be in proper alignment, and thus the wear of the piston and friction of parts will be reduced to the minimum. This form or manner of dividing the cylinder also furnishes proper facilities for finishing the packinggrooves F4, surrounding the bore of the cylinder on each side of the abutment-chamber L, and also for drilling the holes for the temperedsteel coil-springs which engage with the packing-rings situated in the grooves F4 F4. This form et' construction obviates the necessity of fitting the cylinder-extensions info the abutment-chamber L to contain the packing-rings surrounding the annular bore.
It ,will be seen in' Fig. 2 that while the bore ofthe cylinder is annular in form it is anunbroken section in cross-section, except in that part whichl is filled by the piston-disk, which IOO vdisk-is packed steam-tight on either side by packing-ringe fitting in the grooves HH, which rings (not shown) are made in a half-circle and round that partof the abutment-Nnotinclosed joined together by tongue and groove or other similar devices on the line where the two sections E and E ot' the cylinder are joined.
Ou the outsides of the cylinder, near the hub, and over the packing-grooves H H, are formed bosses for the purpose of being bored out to contain the tempered-steel coil-springs which press against the packing-rings in the grooves I"4 F4. rlhese bosses are also provided with caps screwed over or into them tofurnish suitable end bearings for said coil-sprin gs. Each section of the cylinder E and E is formed with projections E3 E3, which furnish suitable supports for the thrust and main bearings of the abutment-shaft N. The ears E2 are also formed on the outside of the sections E and E' of the annular cylinder. double-abutment cylinder, like Figs. 2 and 3,
projections similar to E3 E3 are east on oppof site sides of the ears E2 in order to furnish bearings for abutment-shafts on opposite sid es of the cylinder. This form ot' cylinder admits of the application of a steam-jacket, upon the principle shown in my patent the application for which was tiled November 29,1881, and
which contains a description ofthe other parts of this invention.
0n the outside of the sections or anges which, when the cylinder is bolted together, j form the abutment-chamber L are securedf pockets, with a cap upon the top, (neither of which is shown,) which pockets and cap surin the abutment-chamber L, by which means the abutment or rings may be removed withv out necessitating the taking apart of the two l sections E and E of the annular cylinder. The Hanges ofthe caps forming the sides of the abutmen t-chamber are wider than the sections they are to cover, and are formed with a rim or projection on each side which tits closely over the outer edges of the projections, and so counteract any tendency of the sections E and E' of the cylinder from beingthrown apart by the pressure ofthe steam between the piston and abutment.
The double-abutment cylinder shown in Figs. 2 and 3 may be used in connection with one or with two pistons. When two pistons are employed steam is-admitted simultaneously between each pistou and the closed abutments in rear of the pistons, and, owing to the fact that the pressure on opposite sides of the piston-disk, the cylinder, and drivin g-shat'tis thus equalized and balanced,jl am enabled to einploy an immense pressure of steam without danger of creating any unequal strain or increasing the friction or wear ot' thenioving parts. This form ot' construction ofthe annular cylinder not only avoids the necessity of forming a steam-tight joint around the outer surface of the bore, requiring more labor and more strength of metal, but simplifies the process of construction, and by the use ot' the special tool made for that purpose allows the cylinder to be completelytinished inside without removing the tool therefrom. A
This engine may be constructed with two cylinders, with one piston in each cylinder, andthe cylinders placed in such relation to each other as that one abutment shall suce for both cylinders, the main shafts being so geared together that the steam shall alternatel y till each cylinder, and yet only one abutment be required.
Having fully described my invention, what l claim as new, and desire to secure by Letters Patent, is
l. A cylinder for rotary engines, consisting oftwo sections having one or more abutmentrecesses located at right angles to the bore, and flanges between the hub and abutmentrecesses for the insertion of bolts for fastening the sections together, substantially as shown and described, and for the purposes herein set forth.
2. A cylinder for rotary engines, consisting of two sections, each provided with a semicircular bore for the piston and a connectingchamber for the piston-disk, and furnished with abutment-flanges on one or both sides, and with flanges between the huh and abutmentanges, through which are inserted bolts for securing the sections together, substantially as shown and described, and for thepurposes herein set'ii'orth.
3. A cylinder for rotary engines, consisting of 'two sections, each provided with a semi circular bore forv the piston, a packing-ring groove located on ythe inside of the bore, and -with flanges between the hub and bore for the insertion of bolts for securing the sectionsto'- getlier, substantially as shown and described, and for the purposes herein set forth.
4. A cylinder for rotary engines, consisting of sections provided with interlocking lugs, substantially as shown and described, and for the purpose herein set forth.
