fNiTED STATES PATENT @Tirion HENRY F. COLVIN, OF PHILADELPHIA, PENNSYLVANIA.
INJECTOR.
`SPECIFICATEONforming part of Letters Patent No. 284,614, dated September 11, 1883 f Application filed November 17, IFF?. (Model.)y
To all 107mm/ t may concern,.-
Beit known that I, HENRY F. CoLvIN, a citizen of the United States, residing in the city and county of Phil adelphia, State of Pennsylvania, have invented a new and useful Improvement in Injectors, which improvement is fully set forthfin the following specification and accompanying drawings, in which- Figure l is a central longitudinal vertical section ofthe injector embodying my invention. Fig..2 is a section of the portion vin the line x x, Fig. l.
Similar letters of reference indicate corresponding parts in the two figures.
My invention relates to improvements in injectors for feeding steam-boilers, and has for its object the adaptability of removing and replacing the inner tubes without disturbing any of the couplings or pipe-connections.
A further object is the disposition of the checlcvalve in the injector in suoli manner that the inj ector may be used either vertically, i
horizontally, or at any angleas most desired or required.
Referring to the drawings, A represents the body or shell ofthe injector, the same having an inlet branch, B, a discharge branch, C, a branch, D,lwitl1in which is screwed the steam tube or plug E, and a branch, F, which is closed by a cap, G, it being noticed that the branches B C are opposite each other. The branches D F are opposite each other, the branches BC being at yor about a right angle to the branches D F.
H Krepresents. the combining-tube, J the discharge-tube, and K the check-valve, of the injector, it being noticed that the steam-tube E, combining-tube H, dischargetube J, checkvalve K, and cap G extend in the same right line in the direction from the branch D to the branch F.
The steam-tube E is screwed to the inner wall of the cnd of the branch D, and formed on its inner end with recesses a a, which admit of the application of a suitable wrench to the tube for rotating the same, in order to apply it to and remove it from position.
The ycombining-tube H, has, at the end opposite to the tube E, a flange, b b, which is iitted snugly within the annular partition L, the latter being formed with the body of the injector between the inlet and .discharge branches B C, and the inner face of said partition has a shoulder, c, against Which abuts a shoulder, d, formed on the exterior face of the flange b of the combining-tube.
'The discharge-tube J has, at the end adjacent to the combining-tube, a flange, e, which is threaded and engages with threads on the inner face of the annular partition L, said discharge-tube J thus abut-ting and tightening against the combining-tube H and holding it firmly in position, forming tight joints between the part-s. On the exterior ofthe tube J, outside of thepartition L, are recesses j', which are so disposed that they may be engaged by a suitable wrench in order to rotate said tube and apply it in and remove it from position.
The check-valve K encircles the end ofthe discharge-tube J opposite to the ilange e, said end being exteriorly of cylindrical form to accord with the interior cylindrical form of the body ofthe check-valve, the latter being closed by its -base-plate K', which abuts 'against the end of the tube J as a seat for the valve, the side of the body adjacent to the base-plate being perforated or having ports g, which are uncovered when the valve moves from its normal position. rlhe cap G is recessed or hollow, formin g a chamber, M, which receives a spring, N,whicl1 bears against the valve K and forces it against its seat on the tube J.
P represents the overflow, which is formed by coincident openings in the wall ofthe shell A, the partition L and ilange b of the combiningtube H thus leading to the space between the combining and discharge tubes.
By removing the cap G, the spring N and check-valve K maybe withdrawn and a wrench applied through the branchy F to the dischargetube, vso as to unscrew and remove the same. The combining-tube is then slipped from position and the wrench applied to the steamtube E, so as to unscrew and remove the same, whereby the shell or body A is cleared of all removable parts.
To t together the injector, the tube G is screwed into position, thec-ombining-tube litted in the partition L against the shoulder c, the discharge-tube J screwed to said partition, the check-valve placed over the dischargetube, the spring N located, and the cap G IOO screwed to the branch F, it being noticed that in both cases the parts, excepting the cap G, are applied and removed through the branch F, and said cap, when in position, closes said branch, the operations being accomplished without disturbing any of the couplings or pipe-connections.
As the check-valve is held on its seat by the spring N, it is evident that said valve is operative in any position of the injector.
In lieu of the recesses a f, lugs may be cast with or connected to the plug E and dischargetube J, respectively, for forming means o engagement of the wrench or tool employed to rotate said parts.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
l. An injector-body provided with inlet branch B and discharge branch Cf, said branches being on opposite sides, and partition L, which closes their inner ends, except the necessary passages, in combination. with a combining-tube, H, and discharge-tube J. which are attached to said lpartition, and forni a continuous passage at an angle to said branches, and extending above and .below them, substantially as shown.
2. In an injector, the body or shell and the annular partition having a shoulder on its inner face, in combination with a combiningtube having a shoulder on its exterior face,
and the discharge-tube which tightens against the combining-tube and forms a continuous passage therewith, extending above and below the inlet and discharge branches of the injector body, substantially as and for the purpose set forth.
3. An injector having a check-valve guided by the outside of the discharge, and having its seat thereon, substantially as and for the purpose set forth.
4. In an injector, the discharge-tube and a check -valve iitted thereon, in combination with a spring'bearing against said valve, subst-antially as and for the purpose set forth.
5. -In an injector, a cap closing one of thc branches, and formed with a chamber which receives the spring which closes the cheekvalve, in combination with the discharge-tube, substantially as and for the purposeset forth.
6. An injector having a tubular branch, D, a removable steam-plug, E, with recesses a, a removable combiningtube, I-I, a partition, L, a removable.discharge-tube, J, with recesses f, a removable check-valve, K, and a remov-Y able cap, G, said parts being arranged in the same right line, and combined and operating substantially as and for the purpose set forth.
